Abstract

A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. Additionally, one or more of the blades, distracting mechanism, and handles are offset with respect to the other to facilitate visualization and to increase the space available for an implant holder. The blades are configured to enhance versatility of the distractor. In a first embodiment, the blades are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. In a second embodiment, curved portions are provided between the blades and jaws such that the blades are offset from the jaws in a smooth transition which does not expose sharp edges to internal organs or vasculature of the patient. In a third embodiment, a pair of blades is provided on each jaw such that an implant may be inserted between the spaced apart blades without having a blade engage an external blade-receiving slot in the implant.

Description

SPINAL DISC SPACE DISTRACTOR
The present invention relates to a device and method for spreading apart adjacent vertebrae of a vertebral column so that an implant may be inserted therebetween. More particularly, the present invention relates to a distractor device shaped and configured for minimally invasive insertion and use, such as for distraction of vertebrae using an anterior or anterolateral approach.
Back pain can be caused by either one or a combination of the folowing: a loss of disc height, compression of nerve roots, degenerative disc disease, spondylolisthesis, etc.
The current standard of treatment for people suffering from severe back pain requiring sur, i~cal intervention due to different types of pathology is by intervertebral fusion.
Intervertebral fusion is achieved by fusing two adjacent vertebral bodies together by removing the affected disc and insertion of a suitably sized implant that allows for bone to grow between the two vertebral bodies bn'daing the gap left by the disc removal.
Typically, the intervertebral fusion procedure involves the steps of removing a portion or all of the affected disc material, spreading apart adjacent vertebrae with a distractor, and inserting an implant into the space previously occupied by the removed disc material. This procedure can be done either from the front of the patient (anterior interbody fusion) or from the back (posterior interbody fusion). If done from the front, it is important to reduce the size of the distractor so that the procedure is as minimally invasive as possible and thus minimally interferes with and traumatizes the organs and vasculature between the vertebral region being treated and the insertion point.
Current implants used for interbody fusion include allograft rings/dowels and cages such as threaded cages. However, the technique for the insertion of these implants generally does not achieve distraction because of their height limitations, thus making it difficult to restore the natural disc height. The force necessary to insert such implants (such as a result of drilling and tapping) may cause damage to the vertebrae or vertebral endplates at the insertion site. Moreover, allograft products and cages made out of other brittle materials (e.g., carbon fiber and ceramics) may break during insertion, particularly when distraction is not used and external force is necessary to insert the implant.
Threaded cages on the other hand do not restore lordosis, and do not allow for atraumatic E~~nted ~8 ~-~ ~;
distraction to restore disc height. Thus, there remains a need for improvements in this area.
A surgical instrument set for the insertion of intenrertebral endoprostheses is known fcorn US 4,997,432 KELLER. This known surgical instrument comprises spreading forceps that have, at their front end on each spreading jaw, an essentially U-shaped recess for supporting part of an implant. The arms for the U-shaped recess are angled relative to the longitudinal axis of the forceps. The spreading jaws and the arms remain essentially parallel and evenly spaced from each other when they are spread apart by the scissor-like articulation of the spreading forceps.
In accordance with the principles of the present invention, a spinal disc distracter is provided to allow for an implant insertion technique to be performed during distraction of the disc space. The implants are slid into the disc space between the distracter blades, preferably while the blades are in contact with the upper and lower surfaces of the adjacent vertebral bodies. The distracter of the present invention is formed to be as minimally invasive and atraumatic as possible such that it may readily be used in an anterior or anterolaterlal approach. Thus, the distracter of the present invention is configured to be used in the confined spaces of the human anatomy through a small surgical incision and permits laparoscopic approaches like Balloon Assisted Endoscopic Retroperitoneal Gasless ("BERG"~ approach to be used.
In a preferred embodiment, the distracter of the present invention has a scissor-tike configuration with a pair of handles pivotally connected together. A
distracter jaw is coupled to a distal end of each handle such that movement of the handles together draws the jaws apart to separate the vertebrae being treated. In an even more preferred embodiment, the jaws and handles are pivotally coupled together in a double..
acting scissor-like configuration to further reduce the space required to move the jaws apart and thus further minimizes the invasiveness of the device and procedure.
Although the handles, jaws, and distracter mechanism of the present invention may all lie in the same plane, in order to facilitate visualization of the treatment site during distraction and insertion of an implant, at least handles may be angled away from the plane of the distracter jaws. In a prefer-ed embodiment, the dfstractor mechanism fs AMENDED SHEET

29-12-2000 . CH 009900459 2a angled downward with respect to the jaws and the handles are angled downward vv~th respect to the distractor mechanism to further enhance visualization and also to permit greater space for the implant holder adjacent the proximal end of the distractor during insertion of the implant.
A locking mechanism preferably is provided adjacent to or in the handle to maintain distraction. ThQ locking mechanism may indude a spindle mounted on a first handle and passing through the second handle. An internally threaded speed nut is rotatably AMENDED SHEET
mounted on the threaded bolt such that movement of the speed nut along the bolt selectively inhibits movement of the second handle away from the first handle and thus maintains the vertebrae at the desired distracted position.
The blades of the distractor of the present invention are configured to increase versatility of the distractor. In a first embodiment of the present invention, the blades are removably coupled to the distractor jaws. Thus, the blades may be changed, as necessary or desired, for a given procedure or patient.
In another embodiment, the blades of the distractor are gradually curved to be out of the plane of the distractor mechanism. Because of the gradual curve, the distal end of the jaws may safely be manipulated through the patient's body with as minimal contact as possible with organs and vasculature including major blood vessels such as the vena cava and aorta. Moreover, such curvature permits insertion through a smaller incision because of the increased manipulability of the gradually curved blades through small openings and spaces.
In yet another embodiment, the blades of the distractor are configured to permit insertion of any type of implant. In particular, although certain implants may be provided with slots for engagement with a surface of the distractor blades during insertion, other implants do not have such slots. The blades of the third embodiment of the present invention are configured and sufficiently spaced apart to permit insertion of either type of implant, regardless of whether slots are provided for engaging distractor blades.
The spinal disc distractor of the present invention is thus designed to distract disc space atraumatically with respect to both the vertebrae and the implant during endplate preparation, implant sizing, and implant insertion. The distractor may be used in a straight anterior, anterolateral, or lateral approach, and may be used in either an open or a laparoscopic procedure. Moreover, the distractor is designed to ensure the selection of an anatomically correct implant size by permitting the annulus to be fully stretched so that the largest possible implant may be inserted and compressed upon release of the vertebrae, thereby enhancing stability and assuring correct placement of the implant. Thus, the present invention permits disc height and lordosis to be restored.
The jaws are shaped and configured to preserve the endplate and the vertebral body during distraction, as well as to permit insertion of an implant during distraction. The risk of breakage of ailograft implants and other cages made from brittle materials during insertion is thereby reduced.

In accordance with the principles of the present invention, a distractor 10 is provided with a pair of handles 12a, 12b movable with respect to each other to actuate a pair of jaws 14a, 14b coupled thereto, as shown in Fig. 1. Although distractor 10 may be used for a variety of procedures, a preferred procedure for which distractor 10 is used is spinal disc distraction. Thus, distractor 10 is preferably configured such that actuation of handles 12 (12a, 12b) moves jaws 14 (14a, 14b) apart substantially along distraction axis 16 to a working position corresponding to the desired resulting relative position of the endplates. For example, the blades may be moved to a substantially parallel or lordotic position to separate adjacent vertebrae to be treated.
In order to be optimally useful for use in an anterior approach, handles 12 and jaws 14 are configured to move jaws 14 apart along distraction axis 16 a sufficient amount to adequately separate adjacent vertebrae to be treated (typically 5mm - 20mm, most typically 13mm - 15mm) yet to occupy a minimal amount of space within the insertion region during the procedure. Thus, handles 12 and jaws 14 preferably are pivotally coupled together in a scissors configuration such that movement of handles 12a and 12b together causes jaws 14a and 14b to move apart and effect distraction of vertebrae between which jaws 14 are positioned. Thus, proximal ends 18 of handles 12 are configured to facilitate gripping. In a preferred embodiment, the outer surface of handle proximal ends 18 are contoured to increase user comfort, as shown in Fig. 2.

A biasing element 20, such as a pair of leaf springs, maintains handles 12a, 12b in a spaced apart configuration such that jaws 14a, 14b are dose together, ready for insertion through a small incision and narrow passage through the patient in the neutral configuration cf Fig. 1. A locking mechanism 22 is provided to counteract biasing element 20 as desired, such as to maintain Jaws 14 at a desired spaced apart position for operation on the distracted vertebral region. Locking element may be in any desired configuration, such as a threaded bolt 24 coupled (typically pivotally) to one handle and slidably passing through the other handle, and a locking nut 26 threadedfy and rotatably mounted on the end of bolt 24 extending past the other handle (i.e., the portion not between handles 14). Movement of nut 26, as a result of rotation, along bolt 24 thus shortens the length of bolt 24 between handles 14 and prevents the handles from moving apart, thus maintaining handles 14 in a position closer together than the neutral position.
A distractor mechanism 30 is provided such that movement of handles 12 to actuate distractor mechanism 30 causes jaws 14 to move apart to effect distraction of adjacent element such as vertebrae. Distractor mechanism 30 may be have a simple scissors configuration {such as in Figs. 1A; 14-16 described below) such that handle 12a and Jaw 14a are at opposite ends of a first lever arm and handle 12b and jaw 14b are on opposite ends of a second lever arm pivotally coupled to the first lever arm.
In a preferred embodiment, distractor mechanism 30 is in the form of a double-acting scissor configuration having greater than one pivot point, thus reducing the amount of space required along distraction axis 16 and laterally away from distractor mechanism longitudinal axis 31 to effectuate distraction. As may be appreciated with reference to Figs. 1 and 3, in order to form a double-acting sdssor configuration, handles 12 and jaws 14 are provided on separate lever arms which are pivotally coupled together. In particular, handle 12a is formed at a proximal end of proxtmal lever arm 31 a, handle 12b is formed at a proximal end of lever arm 31 b, jaw 14a is formed at a distal end of distal lever arm 32a, and jaw 14b is formed at a distal end of distal lever arm 32b.
Distal end 34a of proximal lever amp 31 a is pivotally coupled to proximal end 36a of distal lever arm 32a and distal end 34b of proximal lever arm 31b is pivotally coupled of proximal end 36b of distal lever arm 32b. In order to actuate the double-acting mechanism to effectuate distraction and hence movement of jaws 14a, 14b apart upon movement of handles 12a, 12b tagether, one set of lever arms is laterally pivotally AMENDED SHEET

coupled together and the other set of lever arms is crosswise pivotally coupled together. In distracter mechanism 30 of Figs. 1 and 3, proximal lever arms 31a, 31b are laterally pivotally coupled together and distal fever arms 32a, 32b are crossed over each other and pivotatiy coupled together. However, It will be appreciated that, instead, proximal lever arms 31a, 31b may be crossed-over each other and distal lever arms 32a, 32b may be laterally pivotally coupled. The double-acting configuration breaks the pivoting action into two components, reducing the total movement of distracter mechanism 30 required along distraction axis 16.
An additional feature of distracter 10 which facilitates use thereof during distraction is the relative offset positions of jaws 14a, 14b, handles 12a, 12b, and distracter mechanism 30 with respect to one another, as may be appreaated in the side elevational view of Fig. 2. In particular, in a preferred embodiment, distal jaw ends 38a, 38b are to be positioned to properly distract adjacent vertebrae and distracter mechanism 30 and handles 12a, 12b are offset relative to distal jaw ands 38a, 38b to permit optimal visualizafion of distal jaw ends 38a, 38b from the proximal end of distracGor 90 outside the patients body) during distraction. For example, a distal bend 40 may be provided immediately proximal of distal jaw ends 38a, 38b, as may be appreciated with reference to Fig. 2. Thus, the remainder of distracter 10 (i.e., the proximal portions of distracter 10 such as distracter mechanism 30 which ties in vertical plane HH shown in Fig. 2 and handles 12a, 12b which lie in vertical plane HH shown in Fig. 2) is in a different plane from distal jaw plane JJ of distal jaw ends 38a, 38b and the distraction site, With such an offset, visualization of the distraction site and of insertion of the implant therein is enhanced. Additionally or alternatively, a proximal bend 42 may be provided immediately distal of handles 12a, 12b such that proximal handle ends 18a, 18b lie in plane HH
which is offset from distal jaw plane JJ of distal jaw ends 38a, 38b and the distraction site.
The provision of either or both of bends 40, 42 causes at least a proximal portion of distracter 10 to be in a plane different from tire plane of distal jaw ends 38a, 38b and the distraG9on site such that the line of site to view distraction is not obstructed by the distracter. Moreover, such offset of portions of distracter 10, such as distracter mechanism 30 and handles 12a, 12b, from the distal jaw ends 38 accommodate an implant holder for insertion of the implant to permit a substantially straight insertion of the implant holder. Bend 40 may be between 0°-30°, most preferably 10', and bend 42 may be between 0°-30°, most preferably 15°, to achieve the desired improved visualization and increased area for the implant holder.
AMENDED SHEET

A distracter provided in accordance with the principles of the present invention is configured to distract adjacent vertebrae so that an implant may be inserted therebetween. Preferably, each jaw of a distracter formed tn accordance with the principles of the present invention is provided with a blade shaped and configured to contact a vertebral endplate and also to permit insertion of an implant therebetwaen.
Once the implant is properly positioned between the vertebral endplates, the distracter, along with its blades, may be removed from the distraction site in the patient.
In the embodiment of Figs. 1-3, blades 44a, 44b are provided on jaws 14a, 14b, respectively, to engage the vertebrae to be distracted. In a preferred embodiment, blades 44a, 44b are configured and shaped to correspond to a slot 45 in an implant such as cage 46 of Fig. 4 or femoral ring 48 of Fig. 5. The blades 44a; 44b lie in vertical plane BB shown in Fig. 2. Thus, as the selected implant is moved toward the treatment site with a desired insertion tool, implant contacting surfaces 50a, 50b (Fig.
3) of blades 44a, 44b contact respective slots 45. Preferably, implant contacting surfaces 50a, 50b of blades 44a, 44b are closer together than the point of connection 51 a, 51 b of blades 44a, 44b to n3spective jaws 14a, 14b. Thus, jaws 14a, 14b are sufficiently spaced apart to permit insertion of the thictcest dimension of the implant therebetween, yet blades 44a, 44b are closer together to acco~rnt for the narrower dimension of the implant in the region of slots 45 and thereby to securely grasp the implant via slots 45.
Blades 4.4 may converge toward each other in a distal direction before actuation of distracter mechanism 30 as may be appreciated with reference to Fig. 1. Thus, upon actuation of distracter mechanism 30 and pivoting apart of jaws 14, blades 44, and particularly outwardly facing distracting surfaces 52a, 52b (positioned to contact the endplates in the treatrnent site), may be moved into an orientation appropriate for the vertebral region being treated. For example, actuation of distracter mechanism 30 may move distracting surfaces 52a, 52b into a parallel orientation with respect to each other to securely engage endplates which are parallel with respect to each other.
Distracting surfaces 52a, 52b of blades 44a, 44b preferably are shaped to securely engage the vertebrae being treated, particularly the endplates thereof. In a preferred embodiment, distracting surfaces 52a, 52b are configured to securely engage the anterior lip of the vertebral endplates being treated, as shown in the isolated view of AMENDED SHEET

blade 44 in Fig. 6. For instance, distracting surfaces 52a, 52b may be provided with vertebral engagers 54a, 54b (Figs. 2 and 6). such as in the form of ridges.
which engage the endplates. Transverse engagement walls 56a, 56b (Figs. 2 and 6) may be spaced from vertebral engagers 54a, 54b such that an anterior lip of the vertebral endplates fits therebetween. Engagement surface 58a, 58b (Figs. 2 and 6) between vertebral engagers 54a, 54b and engagement walls 56a, 56b preferably is curved to accommodate the anterior lip of the vertebral endplates as well as to provide a smooth transition from distracting surfaces 52a, 52b to transverse engagement walls 56a, 56b.
In accordance with the principles of the present invention, the distractor blades preferably are configured to increase versatility of use of the distractor of the present invention. It will be appreciated that distractor 10 preferably is formed from a surgical grade sterilizable metal such that the same distractor may be used for different patients.
In order to increase the versatility of distractor 10 and its usefulness for different patients and situations, at least one of blades 44a, 44b may be removably coupled to its respective jaw 14a, 14b, as illustrated in Fig. 7. Thus, in such embodiment, jaws 14a, 14b are provided with a socket 60a, 60b shaped to receive a mounting post 62 of a blade 44, as shown in Figs. 7 and 8: Post 62 may be releasably held within a bore 60 of a jaw 14 in any desired manner. For example, a ball detent attachment may be formed by providing a detent 64 in post 62 (Fig. 8) for matingly receiving a biased engagement ball 66 housed within a transverse bore 68 in jaw 14 (Fig. 9). Blade post 62 preferably is fitted within socket 60 to permit pivotable movement of blade 44 about longitudinal axis 70 of blade post 62. Such pivotable movement facilitates manipulation of blade 44 with respect to the vertebral endplates to ease removal of blade 44 and distractor 10. If desired, in order to limit the range of pivotal motion of blade 44, a stop plate 72 (Figs. 6-8) may be provided on post 62 to fit within range limiting groove 74 (Fig. 7) in jaw 14.
Stop plate 72 extends transversely from post 62, as may be appreciated with reference to Fig. 6 and has stop surfaces 76a, 76b engaging respective range limiting surfaces 78a, 78b of range limiting groove 74.
Removable attachment of blades 44 to jaws 14 permits a plurality of differently configured blades to be used with distractor 10 depending on the situation or application. For example, the size of the blade may be selected based on the implant to be inserted, different implants potentially having differently sized slots for receiving a AO
distracter blade. The size of the blade may also be selected depending on the size of the vertebrae being treated or the curvature of the vertebral column. For example, it may be desirable to select blades of different insertion lengths IL1, IL2, as shown in Fig.
10, to account for spondylolisthesis which results in one vertebra V7 being closer to the distracter than the other vertebra V2. Blade selection may also depend on the vertebral region being treated, which may affiect the difficulty of the approach. For example, in the pelvic region organs and bony structures may complicate insertion and blades 44 which are angled, such as 20°-30°, with respect to the longitudinal axis 31 of distracter mechanism 30. Such angled blades 44 would permit an angled approach of distracter to avoid bony structures such as the pelvis.
Although the removability of blades 44 of distracter 10 provide a significant versatility advantage over prior art distracters having blades which are rigidly and fixedly connected to the remaining elements of the distracter, versatility is achievable in accordance with the principles of the present invention in other manners as well. For instance, distal end 102 of distracter 100 of Figs. 92 and 13 is curved such that biades 144 lie in a plane BB, shown in Fig. 12, which is spaced from the remainder of distracter 100 (i.a., the proximal portions of distracter 100 such as distracter mechanism 130 and and handles 172). Such curvature provide several advantages over prior art distracters thus increasing versatility thereof.
For instance, in prior art . distracters, the insertion hole commonly is sized to accommodate the distance between spaced apart elements of the distracter.
However, the gradual and smooth curvature of jaws 714 and blades 144 permits distracter 100 to be manipulated to fit through the insertion hole such as by "snaking"
distracter 100 through. Thus, the curvature of jaws 114 of distracter is selected and configured such that the insertion hole may be sized based on the single element of the distracter with the largest cross-section. Additionaily, the curvature of jaws 114 and blades 144 is smooth and selected such that upon insertion, no sharp edges are present which may injure vasculature, organs, etc., along the insertion path. The curvature thus is sufficiently gentle and wide such that jaws 114 and blades 144 are readily manipulated through the patient's body without causing internal injuries or damage.
Preferably the curvature has an S-shape to permit such manipulation and rounded surfaces.
AMENDED SHEET

In order to provide the above-described curvature in the distal end of distractor 100, a smooth (e.g., radiused without sharp edges) curare 140 which gradually results in distal _ jaw ands 138 being at an obtuse angle with respect to proximal jaw ends 136 may be provided in jaws 114. Additionally, a similarly smooth and gradual curve 141 preferably is provided between distal jaw ends 138 and blades 144 to result in at least a proximal portion of dtstractor 100 being in a different plane than vertical plane BB of blades 144 for enhanced visualization as described with respect to bend 40 of distractor 10.
Preferably, curve 141 results in an angle A between blades 144 and proximal jaw ends 136 of between 0°-30° and most preferably 10°. A bend 142 may also be provided fn handles 112 such that proximal handle ends 118a, 118b are not in the same plane as distal jaw ends 138a, 138b and the distraction site to further enhance visualization, as described above with respect to bend 42 of distractor 10. Bend 142 may be between 0°-30° and most preferably 15°.
It will be appreciated that distractor mechanism 130 is similar to distractor mechanism 30 and the description of distractor mechanism 30 thus is applicable to distractor mechanism 130 and is not repeated herein. Preferably, if dlstractor mechanism 130 is similar to distractor mechanism 30, then blades 144a, 144b converge towards each other in a distal direction, as may be appreciated with reference to Fig. 13, as do blades 44 to permit a rela5ve working orientation appropriate for the treatment site, as described above.
Like blades 44 of distractor 10, blades 144a, 144b preferably are closer together than distal law ends 138a, 138b, as may be appreciated with reference to Fig. 13, such that blades 144a, 144b securely fit within slots 45 of an implant (as in Figs. 4 and 5) to grasp the implant yet jaws 114 permit insertion of an implant therethrough.
Additionally, vertebral engagers 154a, 154b and transverse engagement walls l5fia, 156b, similar to above-described Vertebra! engagers 54a, 54b and transverse engagement walls 56a, 56b, may be provided to enhance engagement of blades 144a, 144b with the endplates at the treatment site as described above in connection with distractor 10.
However, unlike blades 44 of distractor 10, blades 144 of distractor 100 preferably are fixedly secured to jaws 114, such as by formation of blades 144 and jaws 114 as a unitary AMENDED SHEET

piece. Thus. distracter 100 may readily be used in severely calcified areas requiring significant strength and durability of the distracter blades.
The dimensions of blades 44a. 44b of distracter 10 and blades 144a, 144b of distracter 100 are preferaby similar. The thickness T (Figs. 8 and 12) of blades 44a, 44b, 144a, 144b (the working surface, e.g., distracting surfaces 52a, 52b) is preferably approximately 2-15 mm and most preferably approximately 6-10 mm. The width W
(Figs. 6 and 13) of blades 44a, 44b, 144a, 144b is preferably approximately .5-4 mm and most preferably approximately 1.5-1.8 mm. The length L (Figs. 6 and 12) of blades 44a, 44b, 144a, 144b is preferably approximately 5-50 mm and most preferably approximately 25-35 mm.
Versatility of a distracter formed in accordance with the principles of the present invention may alternatively be achieved by the provision of a distracter 200 as shown in Figs. 14-16 with jaws 214 which .permit insertion of any kind of implant, including those not provided with slots as described above with respect to implants 46, 48 of Figs. 4 and 5. Accordingly, each jaw 214 has a pair of blades 244 sufficiently spaced apart to permit insertion of an implant therebetween without necessarily contacting the implant.
Most preferably, blades 244a, 244b are spaced apart a distance D (Fig. 16) to permit insertion of an implant with a medial-lateral width and/or an anterior-posterior width of at least 50% of the corresponding dimension (i.e., medial-lateral or anterior-posterior) of the endplates between which the implant is to be inserted.
As may be appreciated upon comparison of Figs. 12 and 13, blades 244 have a width W along distraction axis 216 greater than thickness T perpendicular to distraction axis 216 (along the working surface). Such dimension minimizes distracting surfaces 252a, 252b to minimize the surface of the endplates contacted by blades 244 and to permit sufficient space for insertion of an implant between blades 244. Thus, contact thickness T of distracting surfaces 252a, 252b is selected to be as small as possible (such that a minimum amount of annulus need be removed and a sufficient amount of space is provided for the insertion of an implant between blades 244a, 244b) while still permitting safe distraction of adjacent vertebrae without causing damage thereto.
Additionally, the width W of blades 244 along distraction axis 216 preferably is selected to ensure the strength of blades 244 so that blades 244 do not deform or buckle during distraction despite the relatively small thickness T of distracting surfaces 252a, 252b.
Preferred dimensions are approximately 3-15 mm (most preferably approximately mm) for width W and approximately .5-8 mm (most preferably approximately 1.5-3 mm) for thickness T. Because of such dimensions. blades 244a, 244b preferably overlap one another when distractor mechanism 230 is in a neutral configuration (with blades 244a. 244b are in their closest relative positions), thereby minimizing the space along distraction axis 216 occupied by blades 244a, 244b and the size of the insertion path necessary for insertion of blades 244 into the treatment site. The length L of blades 244, like length L of blades 44 and 144, is preferably approximately 5-50 mm and most preferably approximately 25-35 mm.
Vertebral engagers 254a, 254b and transverse engagement walls 256a, 256b, similar to above-described vertebral engagers 54a, 54b and transverse engagement walls 56a, 56b, may be provided to enhance engagement of blades 244a, 244b with the endplates at the treatment site as described above in connection with distractor 10.
Blades 244 of distractor 200 preferably are fixedly secured to jaws 214, such as by formation of blades 244 and jaws 214 as a unitary piece. Thus, distractor 200 may readily be used in severely calcified areas requiring significant strength and durability of the distractor blades.
It will be appreciated that distractor mechanism 130 is similar to distractor mechanism 30 and the description of distractor mechanism 30 thus is applicable to distractor mechanism 130 and is not repeated herein.
It will be appreciated that distractor mechanism 230 of distractor 200 may be a simple scissors configuration with handles 212 and jaws 214 formed along the same lever element, as may be appreciated with reference to Figs. 12 and 14. However, distractor mechanism 230 may instead have substantially the same configuration as distractor mechanism 30 of distractor 10 or distractor mechanism 130 of distractor 100.
The description of distractor mechanism 30 thus is applicable to distractor mechanism 230 and is not repeated herein. Conversely, it will be appreciated that distractor mechanism 30 or distractor mechanism 130 may have substantially the same configuration as distractor mechanism 230. Preferably, if distractor mechanism 230 is either scissors-type configuration (single scissors as in Figs. 12-14 or double-scissors as in distractor mechanisms 30 and 130), then blades 244 converge towards each other in a distal direction as do blades 44 to permit a relative working orientation appropriate for the treatment site, as described above.
While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various additions and/or substitutions may be made therein without departing from the spirit and scope of the present invention as defined in the accompanying claims. One skilled in the art will appreciate that the invention may be used with many modifications of structure, forms, arrangement, proportions, materials, and components and otherwise, used in the practice of the invention and which are particularly adapted to specific environments and operative requirements, without departing from the principles of the present invention. The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, and not limited to the foregoing description.
