Definitions
- the present invention relates to the field of creating channels for surgery. More particularly, the present invention relates to less intrusive methods and apparatus for creating surgical channels during procedures such as spinal surgeries.
- Chronic back pain is often caused by a herniated disc or a variety of degenerative spinal disc conditions where the anatomical function of the disc has been disrupted.
- the partially collapsed disc space causes adjacent vertebrae to pinch the nerves extending laterally from the spinal column resulting in chronic pain.
- the prevalent surgical treatment for correcting these types of conditions is to fuse the two vertebrae surrounding the affected disc.
- the first class of procedures accesses the vertebrae from the anterior portion of the spinal column.
- These procedures include a fairly invasive incision through the patient's body, for example through the abdomen, to expose the anterior lumbar portion of the spinal column.
- the affected disc space 110 is distracted to a normal spacing and a pair parallel of cylindrical holes are drilled and tapped in disc space 110.
- Cages 122 and 124 are then inserted into the holes, enabling the vertebrae adjacent to disc space 110 to fuse with the cages over time.
- Figure IB illustrates the second class of procedures which access the vertebrae from the posterior portion of the spinal column. Briefly, this procedure includes exposing the spinal column, and removing portions of the lamina 118 of both the upper and lower vertebrae adjacent to disc space 110. The spinal nerves can now be laterally displaced to access the posterior portion of disc space 110. A pair of holes is drilled and tapped into the distracted disc space 110. Cages 122 and 124 are then inserted in the holes.
- Disadvantages of the posterior approach include the need to remove the protective lamina portion of the vertebrae, and the risk of trauma to the nerve roots and duramater.
- a method and apparatus for creating safer and less intrusive surgical channels is provided. Such procedures reduce risk of trauma and recovery time for the patient.
- the dilatory apparatus includes a guide wire, two or more cannulated dilators, and a guide tube.
- the guide wire is inserted into the patient through a small skin incision.
- a cannulated dilator is inserted over the guide wire.
- Additional cannulated dilator(s) of increasing internal diameter(s) are inserted over the previously inserted dilator(s).
- the guide tube is inserted over the outermost dilator.
- the dilators can now be removed to create a surgical pathway formed by the guide tube.
- lumbar spinal surgery a pair of diagonally aligned cavities are drilled in a spinal disc space using guided pathways created by the dilatory apparatus of the present invention. A pair of vertebrae fusion cages can then be inserted the respective cavities, allowing the vertebrae to fuse together over time.
- the less intrusive channel or pathway may also be useful for other therapeutic and/or diagnostic procedures such as laparoscopy, retroperitoneal surgery and intraperitoneal surgery.
- FIGS. 1A and IB illustrate exemplary conventional anterior and posterior vertebrae fusion procedures, respectively.
- FIG. 2 is a flow diagram illustrating the vertebrae procedure and apparatus of the present invention.
- FIG. 3 is sectional view of a guide wire inserted into a disc space between adjacent vertebrae.
- FIGS. 4A and 4D are sectional views showing the deployment of one embodiment of the serial dilators in accordance with the present invention.
- FIG. 5 shows the deployment of a guide tube of the present invention over dilators of Figures 4A and 4D.
- FIG. 6 shows the guide tube with the dilators removed.
- FIGS. 7 and 8 show the drilling and tapping, respectively, of a disc space in accordance with the invention.
- FIGS. 9 and 10 show the insertion of a cage diagonally from one side of the disc space.
- FIG. 11 show a second cage inserted diagonally from the other side of the disc space.
- Figure 2 is a flowchart illustrating a less invasive procedure for implanting vertebrae fusion cages into a disc space of a patient.
- Figure 3 shows a guide wire inserted into the disc space.
- Figures 4A through 4D, 5 and 6 illustrate the operation of serial cannulated dilators and guide tube of the present invention.
- Figures 7 through 10 show the drilling, tapping and insertion of a cage diagonally into the disc space using the guide tube.
- Figure 11 show both cages inserted into the disc space.
- One method of distraction includes inserting a pair of rigid metal pins (not shown), coupled together by to a lateral direct ion, into a corresponding pair of adjacent vertebrae.
- Pins can be formed from cylindrical stainless steel rods with a threaded leading end.
- the pins are rigidly secured in parallel to each other and perpendicular to the spinal column.
- a distraction tool (not shown), known to one skilled in the art, is used to provide distracting force between the pins, thereby returning disc space 110 to a normal spacing without introducing any relative rotation between the vertebrae (step 210).
- U.S. Patent 4,898,161 teaches a suitable distracting tool and is herein incorporated by reference.
- a guide wire 310 is inserted diagonally into disc space 110 for a depth of approximately 15 to 25 mm (step 220). This depth is preferable because guide wire 310 functions as a guide rod in a manner described below.
- Guide wire 310 can be a Kirschner wire (K-wire) available from SSR/Miltex of Oyster Bay, New York.
- Figure 4 A shows a first cannulated dilator 420 being inserted into the patient using guide wire 310 as a guide.
- first cannulated dilator 420 is inserted over guide wire 310, the surrounding tissue is distended to the diameter of dilator 420.
- a second cannulated dilator 430 is then inserted over first dilator 420, further distending the surrounding tissue.
- a third cannulated dilator 440 is inserted over second cannulated dilator 430. See step 230.
- a skin incision of about 20 mm is made prior to the insert of dilators 420, 430 and 440.
- cannulated dilators While three serial cannulated dilators are described in this embodiment, other embodiments which include one or more cannulated dilators are possible. In addition, depending on the surgical procedure, it is also contemplated that the cannulated dilators have varying wall thickness and a variety of lengths. For example in spinal surgery, the wall thickness may range from 2 to 5 mm and the length may range from 100 to 200 mm. Suitable materials for cannulated dilators 420, 430 and 440 include metals, plastics, and ceramics known to one skilled in the surgical instrumentation art, such as titanium or hardened aluminum.
- a guide tube 550 is inserted over the plurality of dilators 420, 430 and 440, which can then withdraw leaving a surgical channel 665 within guide tube 550 (steps 240 and 250).
- guide tube is about 16 to 20 mm in diameter and 100 to 150 mm in length.
- the wall of guide tube 550 is approximately 1 mm.
- Suitable materials for guide tube 550 include metals, plastics and ceramics used for surgical instruments, such as stainless steel, titanium, and aluminum.
- a hole is drilled into disc space 110 via surgical channel 665 (step 260).
- Guide tube 550 and K-wire 310 function together to protect the surrounding tissues while guiding the drill into disc space 110.
- Figure 8 shows a tap 880 with its threading head in disc space 110 and its tool body in guide tube 550 (step 270). Drills, drill bits and taps are commercially available from Stryker Corporation of Kalamazoo, Michigan, and Medtronic Sofamor-Danek of Memphis, Tennessee.
- a fusion cage 122 is inserted into the tapped hole in disc space 110 using an insertion tool 990 (step 280).
- fusion cages available commercially, including BAKTM cage from Spine-Tech of Minneapolis, Minnesota, and LT-CAGETM and INTER FIXTM cages from Medtronic Sofamor-Danek of Memphis, Tennessee.
- steps 220 through 280 are repeated to insert a second fusion cage 124 diagonally opposed to the first fusion cage 122.
- guide tube 550 may have a rough leading edge so that it can secure the vertebrae adjacent to disc space 110, thereby increasing the stability of surgical channel 665. Drilling and tapping of disc space 110 may be accomplished without guide wire 310.
- dilators 420, 430 and 440 without guide wire 310.
- a relatively small surgical channel 665 in needed, and a single dilator 420 may be sufficient.
- guide tube 550 is preferably thinner than dilators 420, 430 and 440, conceptually, guide tube 550 is a thin-walled outmost dilator.
- Surgical channel 665 can be used with different types of diagnostic and surgical procedures.
- Exemplary diagnostic and therapeutic applications for surgical channel 665 include placement of internal distractor for correction of scoliosis, retroperitoneal surgery and intraperitoneal surgery.
