Definitions

  • the present invention relates to arthroscopic surgical instruments.
  • the present invention relates to arthroscopic surgical instruments which incorporate a suc ⁇ tion capability.
  • Arthroscopic surgical instruments are instruments used in the surgical repair of joints where the joint is not exposed by a large incision.
  • Arthroscopic surgical instru ⁇ ments generally include an actuating handle coupled by a tube and push rod to an end effector assembly.
  • the end effector assembly typically includes a pair of jaws, one of which is rotatably coupled to the other, thereby allowing articulation of one jaw relative to the other.
  • Arthroscopic cutting instruments typically include jaws which achieve a cutting action through a punch and die configuration which severs the tissue from the joint by punching the tissue with a sharp edged jaw through a die.
  • the die typically takes the form of a fixed jaw, while the punch takes the form of a movable jaw which rotates relative to the fixed jaw from an open position to a closed position when cutting.
  • Arthroscopic surgery is performed on joints of the body to remove damaged cartilage, bone tissue, and spurs, and to repair ligament damage.
  • small incisions are made around the joint, and a cutting tool, a fiber optic device, and a suction tube are inserted through the incisions.
  • the practitioner cuts away damaged cartilage using the cutting tool while viewing the surgical site through the fiber optic device.
  • the cut cartilage is removed from the body either by grasping the cut cartilage with the cutting tool and removing the cutting tool from the incision, or by using the suction tube to vacuum the cartilage out of the joint area.
  • a disadvantage of removing the cut cartilage with the cutting tool is that the practitioner needs to remove the cartilage after every cut, thereby inserting and withdrawing the cutting tool many times over.
  • U.S. Patent 4,522,206 to hipple et al. shows an arthroscopic surgical instrument having an outer tube, an inner tube which is in contact with, extends axially within, and moves within the outer tube, a suction source coupled to the outer tube at a proximal end thereof, a movable upper jaw, and a fixed lower jaw.
  • the movable upper jaw has an upper portion coupled to the inner tube at a flexible exten ⁇ sion thereof, and the fixed lower jaw is formed at the distal end of the outer tube.
  • the movable jaw is coupled to the fixed jaw by a pivot pin or stub pins near the lower portion of the outer tube.
  • Axial movement of the inner tube causes the movable jaw to open and close relative to the fixed jaw.
  • the outer tube and inner tube together provide a fluid path from the suction source at the proximal end of the instrument to the jaws at the distal end of the instru ⁇ ment.
  • the provided configuration facilitates suctioning of the cartilage (and fluid) out of the joint area via the jaws and fluid path after the cartilage is cut.
  • the inner tube is coupled to the movable jaw by a flexible portion of the inner tube which is used to close the jaw by pushing the inner tube toward the jaws.
  • This arrangement is incapable of achieving a strong cutting action because the pushing force cannot be arranged to be as great as a pulling force, and because the location of attachment relative to the movable jaw does not provide a large mechanical advantage.
  • a second disadvantage of the Whipple et al. instrument is that the movable jaw is con ⁇ nected to the fixed jaw by means of a pivot pin or stub pins. The pivot or stub pin connection is a common failure point for the instrument because of its weakness.
  • the instrument is that the inner tube which is attached to the movable jaw and is used to actuate the movable jaw, moves axially inside the hollow tube.
  • the axial movement creates friction while opening and closing the upper movable jaw relative to the lower fixed jaw and makes the instrument more difficult to actuate.
  • the closing action is accomplished when a push rod pulls the jaws closed, which permits a higher force to be applied.
  • Construction of the jaw assembly of the parent application requires that the bottom of the fixed jaw be open. As a result, there is no way to provide suction at the distal end of the instrument.
  • the arthroscopic surgical instrument of the invention broadly includes a surgical punch end effector assembly, a hollow tube defining a fluid passageway, a push rod extending through the hollow tube, an actuating mechanism coupled to a proximal end of the push rod, and a fluid coupler extending into the hollow tube at a proximal portion thereof and coupled to a vacuum source which applies suction through the fluid passageway.
  • the end effector assembly has a movable punch end effector which is coupled to the push rod, and a stationary die end effector.
  • the stationary die end effector includes a separate upper die portion and a separate lower cup portion, both of which are coupled to the distal end of the hollow tube.
  • the upper die and lower cup portions are fixed together at the end of an assembly procedure.
  • the upper die portion of the sta ⁇ tionary die end effector has a groove into which a tongue of the movable end effector is fitted prior to fixing the separate portions of the stationary end effector.
  • the cavity is essen ⁇ tially defined on the bottom by the lower cup portion, at the front by the lower cup portion and the upper die por ⁇ tion, and at the top by the movable end effector.
  • the actuating mechanism for the push rod preferably includes a fixed handle portion which is coupled to the proximal end of the hollow tube and a movable lever portion which is coupled to the proximal end of the push rod.
  • the movable lever portion pivots relative to the fixed handle portion and imparts a reciprocal axial motion to the push rod which causes the opening and closing of the end effector assembly.
  • Preferred embodiments of the arthroscopic surgical instrument include: providing the proximal end of the annu ⁇ lar passageway with a fluid seal which extends around the push rod; providing the fluid coupler as a socket on the fixed handle portion of the actuating mechanism; and provid ⁇ ing the upper die portion and lower cup portion of the stationary die end effector with locking mechanisms so that they attach together as well as attaching to the distal end of the hollow tube without welding.

  • the shank segments 44e, 46e of the stationary end effector 40 enter the hollow tube 12.
  • Con ⁇ tinued movement of the push rod 19 with the end effector assembly 18 causes the outer radial projections 62 and 72 of the shank segments 46e, 44e to enter the hollow tube 12 and to slightly deflect the slightly resilient undercut portions 60, 70 of the shanks.

  • the fluid seal 135 is shown fitting frictionally within the proximal end 16 of the hollow tube 12 which is located within the fixed handle portion 20a of the actuating assembly 20. In this manner, and with the flange 139 of the fluid seal 135 abutting the proximal end 16 of the hollow tube 12, the fluid seal 135 blocks and seals the annular passageway 27. As shown in Fig. 4, the push rod 19 extends axially through the hollow tube 12, through the center bore 136 of the fluid seal 135, and through the O-rings 138.
  • the inner radial groove 137 of the fluid seal 135 prevents the O-rings 138 from slipping out of the fluid seal 135 when the push rod 19 is moved axially through the hollow tube 12 and rubs against the O-rings 138.
  • the O-rings 138 thus provide a mechanism for permitting movement of the push rod 19 while preventing leakage out the proximal end of the hollow tube 12.

Abstract

Un instrument chirurgical arthroscopique (10) comporte un ensemble effecteur chirurgical d'extrémité (18) à poinçon, un tube creux (12) définissant un passage de fluide, un poussoir (19) s'étendant dans le tube creux, un levier d'actionnement (20b) accouplé à une extrémité proximale (16) dudit poussoir, un accouplement (28) pour fluide s'étendant dans le tube creux et assurant la liaison avec une source de vide permettant de produire une aspiration dans le passage de fluide (27). L'ensemble effecteur d'extrémité (18) présente un poinçon mobile et des effecteurs d'extrémité stationnaires à matrice (42, 40). Lorsque l'effecteur d'extrémité mobile à poinçon est monté pivotant dans l'effecteur d'extrémité stationnaire (40) à matrice, et que les effecteurs d'extrémité sont en position fermée, une cavité pratiquement fermée ou creuse (104) présentant un ouverture proximale donnant dans le tube est formée dans les effecteurs d'extrémité. Le tissu découpé par l'effecteur d'extrémité mobile (42) tombe dans la cavité et, la cavité étant pratiquement fermée, le tube d'aspiration s'étend dans la cavité, aspire le tissu et l'envoie dans le passage de fluide (27).
