Description
- The present application claims priority to, and the benefit of, U.S. Provisional Patent Application No. 60/995,023, filed on Sep. 24, 2007, the entire contents of which are hereby incorporated by reference.
- 1. Technical Field
- The present disclosure relates generally to a surgical apparatus for use during anastomosis procedures. More particularly, the present disclosure relates to methods and apparatus to deliver an anvil assembly to a surgical site.
- 2. Description of the Related Art
- Surgical anastomosis is the surgical connection of severed or separate of hollow organs. Typically, an anastomosis procedure follows another surgical procedure where a diseased or defective section of hollow tissue is removed and the remaining end sections are joined. The end sections may be joined by circular, end-to-end, or side-to-side organ reconstruction methods.
- In a circular anastomosis procedure, the two ends of the organ sections are joined by means of a stapling instrument that drives a circular array of staples through the end section of each organ section and simultaneously cores any tissue interior of the driven circular array of staples to free the tubular passage. Examples of instruments for performing circular anastomosis of hollow organs are described in U.S. Pat. Nos. 7,168,604; 6,053,390; 5,588,579; 5,119,983; 5,005,749; 4,646,745; 4,576,167; and 4,473,077, each of which is incorporated herein in its entirety by reference. Typically, these instruments include an elongated shaft having a handle portion at a proximal end to actuate the instrument and a staple holding component disposed at a distal end. An anvil assembly including an anvil rod with an attached anvil head is mounted to the distal end of the instrument adjacent the staple holding component. Opposing end portions of tissue of the hollow organ(s) to be stapled are clamped between the anvil head and the staple holding component. The clamped tissue is stapled by driving one or more staples from the staple holding component so that the ends of the staples pass through the tissue and are deformed by the anvil head. An annular knife is concurrently advanced to core tissue within the hollow organ to free a tubular passage within the organ.
- Certain circular anastomosis procedures entail minimally invasive techniques. In these procedures, surgeons often position an anvil assembly in the desired hollow organ by inserting an anvil delivery system through a patient's esophagus. U.S. Pat. No. 7,179,267, for example, describes a method and apparatus for delivering an anvil assembly through a patient's esophagus. Although surgical apparatus that can deliver an anvil assembly into a hollow organ are well-known in the art, there is a need for more versatile anvil delivery systems.
- The present disclosure relates to an anvil delivery system including an anvil assembly, a flexible tube, and a fitting coupled to the flexible tube. The fitting includes a body having a proximal end portion and a distal end portion, and a tip on the distal end portion. The proximal end portion is adapted to attach the body of the fitting to the flexible tube. The tip is configured for insertion into a body lumen.
- The present disclosure also relates to an anvil delivery system comprising an anvil assembly, a flexible tube having a first end portion and a second end portion, and a fitting. The fitting has a proximal end portion and a distal end portion, wherein the proximal end portion is removably coupled to the second portion of the flexible tube and the distal end portion includes a tip for advancing through tissue.
- In one embodiment, anvil delivery system further includes a bore extending through the distal end portion of the fitting to receive a suture. In one embodiment the anvil delivery system includes a plurality of protrusions disposed on a proximal end portion of the body of the fitting. In one embodiment, the anvil is pivotable with respect to the flexible tube.
- The present disclosure also relates to a kit. The kit includes a flexible tube having a distal end an open proximal end, an adapter configured to be releasably secured to the flexible tube, and a fitting configured to be attached to the flexible tube after the distal end of the flexible tube has been cut. The fitting includes a body having a proximal end portion configured to attach to the flexible tube and a distal end portion.
- In one embodiment, the kit also includes the anvil assembly.
- In one embodiment, the proximal end portion of the body of the fitting is dimensioned to be supported within the flexible tube.
- In one embodiment, the tip is blunt and configured for insertion into a body lumen. In one embodiment, the fitting includes a bore extending through the distal end portion of the body. In one embodiment, the plurality of protrusions is adapted to operatively attach the body of the fitting to the flexible tube.
- The present disclosure also relates to method of performing a surgical procedure comprising:
- providing an anvil assembly having an anvil head and a flexible tube having a first end portion extending from the anvil assembly;
- cutting a second end portion of the flexible tube, the second end portion being disposed on an opposite end of the flexible tube from the first end portion;
- attaching a fitting to the second end portion of the flexible tube, the fitting having an insertion tip;
- inserting the second end portion of the flexible tube into a body;
- positioning the anvil assembly within the body using the flexible tube; and
- detaching the flexible tube from the anvil assembly while the anvil assembly is positioned within the body.
- The fitting may include a bore to receive a suture and the inserting step may include the step of grasping the suture to pull the insertion tip to advance the fitting, flexible tube and anvil assembly. The step of attaching the fitting may include the step of inserting a portion of the fitting within the second end portion of the flexible tube to frictionally engage the tube.

Further,center rod 20 includesflexible legs 26 configured to capture at least a portion ofadapter 14 therebetween. - With continued reference to
FIGS. 2 and 3 ,adapter 14 includes afirst end 14 a dimensioned to be received withinopen end 12 a offlexible tube 12 and a second end 14 b configured to be received in thecenter rod 20 ofanvil assembly 16. First end 14 a includes a series ofannular rings 22 dimensioned to frictionally retainfirst end 14 a ofadapter 14 withinopen end 12 a offlexible tube 12. It is envisioned that other retaining structure can be provided to retain first end 14 b ofadapter 14 toflexible tube 12, e.g., clamps, pins, threads, etc. Second end 14 b ofadapter 14 includes alongitudinal guide member 24 dimensioned to be received betweenflexible legs 26 ofcenter rod 20 ofanvil assembly 16. In addition, second end 14 b ofadapter 14 is dimensioned to allowcenter rod 20 ofanvil assembly 16 to freely slide on and off second end 14 b ofadapter 14. - Referring to
FIG. 4 ,anvil head 30 ofanvil assembly 16 includes spaced apartopenings 32 that are in communication with each other.Adapter 14 includes afirst throughbore 40 formed in acentral hub portion 14 c and asecond throughbore 42 formed infirst end 14 a. As will be discussed below,anvil delivery system 10 includes asuture 50 to secureanvil assembly 16 toadapter 14. - Referring to
FIGS. 2 and 4 ,suture 50 has afirst end 50 a and asecond end 50 b. To secureadapter 14 toanvil assembly 16,first end 50 a ofsuture 50 is inserted into oneopening 32 ofanvil head 30 and pulled out of theother opening 32 such that the ends 50 a and 50 b ofsuture 50 are positioned on opposite sides ofcenter rod 20 ofanvil assembly 16. Next, second end 14 b ofadapter 14 is positioned withincenter rod 20 and each end 50 a and 50 b ofsuture 50 is inserted through an opposite end ofthroughbore 40 ofcentral hub portion 14 c ofadapter 14 to define a first suture loop 54 (seeFIG. 2 ). Eachend suture 50 is pulled tight such thatadapter 14 is held againstcenter rod 20. Thereafter, each end 50 a and 50 b is inserted through an opposite end ofthroughbore 42 offirst end 14 a ofadapter 14 to define a second suture loop 56 (seeFIG. 2 ).Second suture loop 56 extends aboutfirst end 14 a ofadapter 14. The frictional contact betweenrings 22 offirst end 14 a ofadapter 14 and the inner surface offlexible tube 12 securesadapter 14 toflexible tube 12 and preventssuture 50 from loosening up. - With reference to
FIGS. 1A and 1B , after operatively connectingflexible tube 12 toanvil assembly 16 viaadapter 14, a healthcare professional may decide to shortenflexible tube 12. In some bariatric surgeries, for instance, shortflexible tubes 12 are beneficial. Therefore, the healthcare professional may decide to cutflexible tube 12, thereby creating another open end 12 b on the new distal end offlexible tube 12. Because the cut end offlexible tube 12 may be abrasive and/or include jagged or irregular surfaces, a fitting 62 may be attached to open end 12 b oftube 12 to facilitate smooth atraumatic passage oftube 12 through or into a body lumen. - With reference to
FIGS. 5-9 , fitting 62 includes abody 64 having aproximal end portion 66 adapted to be supported in open end 12-b offlexible tube 12, adistal end portion 68, and amiddle portion 70.Distal end portion 68 has bore 74 defined therethrough and ablunt tip 72 configured for insertion into a body lumen such as the esophagus. In a preferred embodiment, thetip 72 is bullet-shaped to aid insertion.Bore 74 may be dimensioned to receive a suture (not shown) so it can pulled through the lumen if desired.Middle portion 70 is betweenproximal end portion 66 anddistal end portion 68.Proximal end portion 66 includes a plurality ofprotrusions 76 adapted to frictionally retainproximal end portion 66 of fitting 62 within open end 12 b offlexible tube 12. - In operation, a surgeon employs
anvil delivery system 10 to positionanvil assembly 16 in the body during minimally invasive procedures. During such procedures, the surgeon initially securesadaptor 14 to openend 12 a offlexible tube 12 andsutures anvil assembly 16 tocentral hub portion 14 c ofadapter 14.Flexible tube 12 may then be cut at any desired length. The cut creates a distal open end 12 b from the blunt closed end inflexible tube 12. After cuttingflexible tube 12, the surgeon secures fitting 62 in open end 12 b. Specifically,proximal end portion 66 of fitting 62 is inserted into open end 12 b. The frictional contact betweenprotrusions 76 ofdistal end portion 66 of fitting 62 and the inner surface offlexible tube 12 secures fitting 62 toflexible tube 12. - For transoral applications, once fitting 62 has been secured to
flexible tube 12, the surgeon inserts fitting 62 in the patent's mouth and moves fitting 62 along withflexible tube 12 down through the esophagus to the surgical site, e.g., stomach. It is also contemplated that the anvil delivery system can be used for other applications besides transoral insertion, such as transgastric and transanal approaches for colorectal, bariatric and other applications. This can be achieved due to the bullet shaped tip which can penetrate tissue, e.g. the stomach wall to deliver the anvil assembly. Other penetrating tip configurations could be provided. - After insertion, the surgeon should then make a small incision at the surgical site to create an inner access to the fitting 62. After making the incision, the surgeon pulls fitting 62 through the incision, thereby pulling
anvil assembly 16 through the esophagus (or other body tissue or organ depending on the procedure) to the surgical site. If a suture is used throughbore 74, the suture can be grasped and pulled to pull the anvil assembly. Asflexible tube 12 is pulled through the incision, the distal end ofcenter rod 20 ofanvil assembly 16 advances through the incision. Whenanvil assembly 16 is properly positioned at the surgical site, the surgeon may releaseadapter 14 fromanvil assembly 16 by cuttingsuture 40 and slidingcenter rod 20 from end 14 b ofadapter 14. Next, the flexible tube 12 (with fitting 62) andadapter 14 may be pulled from the body through the incision. The surgeon can now mountcenter rod 20 ofanvil assembly 16 on a surgical stapling device (not shown) and perform the desired surgical procedure. - The components of
anvil delivery system 10 may be provided in kit form. The kit may include aflexible tube 12 adapted to be secured to theanvil assembly 16, anadapter 14 configured to secure ananvil assembly 16 to theflexible tube 12 and a fitting 62 configured to be attached toflexible tube 12. Fitting 62, in turn, may include abody 64 having aproximal end portion 66 and adistal end portion 68, ablunt tip 72 disposed on thedistal end portion 68, and a plurality ofprotrusions 76 disposed on theproximal end portion 66.Proximal end portion 66 ofbody 64 may be dimensioned to be supported withinflexible tube 12. The plurality ofprotrusions 76 may be adapted to operatively attach thebody 64 of the fitting 62 toflexible tube 12.Blunt tip 72 may be configured for insertion into a body lumen. Fitting 62 may include abore 74 extending throughdistal end portion 68 ofbody 64. The kit may further include ananvil assembly 16. In one embodiment, theanvil assembly 16, theflexible tube 12, andadapter 14 are fastened together with asuture 50, as discussed above, and the fitting 62 is provided to blunt the end offlexible tube 12 if theflexible tube 12 has to be cut and to provide an insertion tip. - With reference to
FIGS. 10A and 10B , another embodiment ofanvil delivery system 10 includes analternative fitting 82. Like fitting 62, fitting 82 is attached to open end 12 b oftube 12 to facilitate smooth atraumatic passage oftube 12 through or into a body lumen. Since the structure and operation of ananvil delivery system 10 with fitting 62 is substantially identical to the structure and operation of ananvil delivery system 10 with fitting 82, the present disclosure only discusses in detail the structural features of fitting 82. - Referring to
FIGS. 11-14 , fitting 82 includes abody 84 having aproximal end portion 86 supported in open end 12 b offlexible tube 12, adistal end portion 88, and amiddle portion 90.Distal end portion 88 has abore 94 defined therethrough and ablunt tip 92 configured for insertion into a body lumen such as the esophagus.Body 90 of fitting 82 has a taperedsurface 98 leading toblunt tip 92.Tip 92 is bullet-shaped to aid insertion.Bore 94 is dimensioned to receive a suture (not shown). The suture is attached to tip 92 and pulled to pulltube 12 through a lumen if desired.Proximal end portion 86 includes a plurality ofprotrusions 96 adapted to frictionally retainproximal end portion 86 of fitting 82 within open end 12 b offlexible tube 12.Protrusions 96 are disposed around an outer periphery ofproximal end portion 86. - It will be understood that various modifications may be made to the embodiments disclosed herein. For example, the particular configuration of fitting 62 need not be exactly as shown but rather may be configured in any manner capable of facilitating atraumatic passage of
tube 12 through a body lumen. Therefore, the above description should not be construed as limiting, but merely as exemplifications of the embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
