Definitions

  • the present invention relates to an apparatus for use in the performance of ankle arthroscopy procedures and, more particularly, to an improved clamp assembly for use with a non- invasive ankle joint distraction system in support of arthroscopic procedures.
  • a removable strap is attached to the patient's foot and the opposite end of the strap is strung to an outrigger fixed to and extending several feet away from the foot of the operating table.
  • Variable distraction force is applied in a direction generally axially of the patient's leg with a manually operated crank and pulley system.
  • the method provides good distraction and the ability to control the amount of the distraction force.
  • the horizontal position of the leg and foot results in difficult access to posterior portals of the ankle and also results in the problem of water or saline solution running down the arthroscope and into the camera.
  • the outrigger mechanism may also create an obstacle to the surgeon.
  • the need to convert to invasive distraction means requires complete repositioning of the patient which is cumbersome and time consuming.
  • the patient is positioned supine at the end of the operating table with the hip and knee flexed and the lower leg depending downwardly from the end of the table over a padded horizontal bar behind the knee.
  • Distraction of the ankle joint is provided by pulling vertically downward on a strap attached to the foot of the patient and secured to a pivotal cantilevered arm below the table.
  • This method does not offer much variation in position and requires careful attention to the potential circulatory problems attendant the application of pressure to the popliteal area with the knee acutely flexed over the padded bar.
  • My prior U.S. Pat. No. 5,290,220 describes a non-invasive distraction technique which allows variable positioning of the ankle above the operating table to accommodate access to the ankle joint from any direction.
  • the non- invasive methods disclosed in this patent utilize an adjustable distraction device attached between the foot of the patient and the Clark rail on the operating table to provide a variable level of joint distraction.
  • a deficiency in the system disclosed in this patent has been noted.
  • the deficiency is that the serrated surfaces on the adjustable clamp only allow the distraction system to be fixed in a specified number of angular positions with respect to the operating table.
  • a conventional operating table is used to support the patient on his back in a generally horizontal position.
  • a conventional urology leg holder is used to support the patient's leg posteriorly of the knee joint where it may be maintained in a selected position between full extension (horizontal) and acutely flexed, with the leg holder attached directly to the operating table below the knee and including means for adjusting the height at which the knee joint is held above the table.
  • the distraction means includes an elongate body having an axially adjustable length and a first end by which it is attached to the foot of the patient.
  • a manually operable or rotatable lever arm has one end attached to the operating table and an opposite end attached to the second end of the body of the distractor.
  • An improved adjustable clamp assembly is attached to one edge of the operating table and includes first clamping means to fix the position of the clamp assembly along the table edge and a second clamping means to which the opposite end of the lever arm is attached, permitting the lever arm to be rotated manually in a generally vertical plane and clamped in an initial selected position to impose a tensile load on the distractor and an initial level of distraction of the ankle joint.
  • the initial level of ankle joint distraction may be varied by adjusting means on the distractor device.
  • the improved clamp assembly includes high friction, knurled surfaces on the engagable portions of the second clamping means.
  • the knurled surfaces can be engaged in any orientation and allow the lever arm secured by the second clamping means to be placed in an infinite number of angular positions with respect to the operating table.
  • the clamp assembly may also include a washer formed of a deformable material positioned between the knurled surfaces to enhance the engagement of the knurled surfaces with each other.
  • FIG. 1 is a side elevation view showing the apparatus of the present invention attached to a patient with the leg in a slightly flexed position.
  • Fig. 2 is a side elevation view similar to Fig. 1 showing the leg of the patient in a more acutely flexed position.
  • Fig. 3 is a side elevation view showing the apparatus of the present invention utilized with the hinged end of the operating table tilted downwardly.
  • Fig. 4 is a side elevation view similar to Fig. 3 showing the hinged end of the table tilted further downwardly.
  • Fig. 5 is an end elevation view of the apparatus and patient taken on line 5-5 of Fig. 4 and in a plane generally parallel to the hinged end of the table.
  • Fig. 6 is a cross-sectional view along line 6-6 of Fig. 5.
  • Fig. 7 is a cross-sectional view along line 7-7 of Fig. 6.
  • Fig. 8 is a sectional view along line 8-8 of Fig. 6.
  • Fig. 9 is an exploded view of the clamp assembly of the present invention.
  • a conventional operating table 10 includes a standard Clark rail 11 attached to one lateral edge of the table in a well known manner.
  • the patient is positioned supine on the operating table 10 with the leg 12 of the patient supported at the back of the knee vertically above the table.
  • the leg is only slightly flexed (nearly horizontal).
  • Leg support is provided by a conventional gynecological or urological leg holder 13 attached in a known manner to the Clark rail 11.
  • the leg holder 13 includes a support arm 14 adjustably attached to the
  • Clark rail 11 by a clamp 15 which allows the assembly to be slid along the rail, pivoted in a horizontal plane, and moved vertically up or down.
  • the upper end of the support arm 14 is connected to the leg holder 13 with a pivot mechanism 16 that allows the holder to be adjustably pivoted in either a horizontal or a vertical plane.
  • the leg holder 13 can easily be adjusted in three planes of rotation and its height readily varied as will be described hereinafter.
  • the leg is generously padded with a heavy foam rubber padding 17 to provide as much cushioning as is practicable, thereby minimizing as much as possible pressure on the posterior thigh and leg, primarily in the popliteal area.
  • the distraction apparatus of the present invention includes an axially adjustable distractor 18 attached by a first end 20 to the foot of the patient and by a second end 21 to the operating table, via a lever arm 22 having one end 23 pivotally attached to the Clark rail and the other end 24 connected to the second end 21 of the distractor 18.
  • a foot strap 25 including an adjustable VELCRO fastener band 26 placed around the ankle above the heel and instep and a connecting strap 27, including looped ends 28 on either side of the foot through which the VELCRO fastener band 26 is threaded.
  • the doubled connecting strap 27 is threaded through a connector loop 30 attached to the first end 20 of the distractor by a swivel joint 31.
  • the main body of the distractor 18 comprises a threaded bolt 32 to which the swivel joint 31 is attached.
  • the threaded bolt 32 can be any desired length in order to reduce the cost of the distractor 18, so long as the bolt is of a sufficient length to provide the desired function.
  • a length adjustment mechanism 33 is attached to the second end 21 of the threaded bolt 32.
  • the adjustment mechanism includes a manually operable, threaded adjustment nut and an attached mount 35 for an attachment strap 36.
  • the mount 35 is connected to the adjustment nut 34 with a swivel connection so that the adjustment nut 34 can be rotated on the threaded bolt 32 to change the position of the adjustment mechanism therealong without rotating the mount 35 or attachment strap 36.
