Abstract

Hand-held surgical assembly for use in performing a laparoscopic medical procedure, comprising a housing. An actuator tube having a bore therein is slidably mounted in the housing. A handle operated mechanism is carried by the housing for causing reciprocatory movement of the actuator tube assembly within the housing.

Claims

1. A hand-held surgical device for use with a tool having proximal and distal extremities, the tool having tool parts and an actuation mechanism for operating the tool parts, the tool parts being disposed at the distal extremity of the tool and the proximal extremity being sized to be adapted to be grasped by the human hand and for use in performing a laparoscopic medical procedure comprising a handle assembly having proximal and distal extremities and having a bore extending therethrough from the proximal extremity to the distal extremity, said bore being sized so that the tool can be removably positioned within the bore so that the tool parts extend out of the bore at the distal extremity of the handle assembly and so that the proximal extremity of the tool remains out of the bore at the proximal extremity of the handle assembly to permit the tool to be grasped by the human hand to facilitate positioning of the tool within the bore, said handle assembly including hand operated means adapted to cause operation of the actuation mechanism of said tool and for causing rotational movement of the tool.

2. A device as in claim 1 wherein said hand operated means includes a handle member movable towards and away from the housing.

3. A device as in claim 1 wherein said handle assembly is formed so that it is adapted to be engaged by the human hand and to be held in a generally vertical position and a trigger handle movable in a direction generally perpendicular to the vertical position.

4. A device as in claim 3 wherein said handle assembly includes means for mounting said trigger handle so that it moves in a parallelogram-like fashion.

5. A device as in claim 3 together with means carried by the housing adapted to be grasped by the thumb of the human hand so as to provide a counterforce to the finger actuation of the hand on the trigger handle.

10. A device as in claim 1 wherein said tool parts are in the form of serrated jaws.

11. A device as in claim 10 wherein said serrated jaws are formed of a metal and further including a covering mounted on said jaws and having spaces therein exposing the metal of the jaws.

12. A device as in claim 11 wherein said tool parts are in the form of opposed clam shells.

13. A device as in claim 12 wherein said clam shells have exposed exterior surfaces and metal knife-like edges and further including insulating material covering substantially all of the exterior surfaces of the clam shells but excluding the knife-like edges.

6. In a hand-held surgical assembly for use in performing a laparoscopic medical procedure, a hand-held endoscopy device having distal and proximal extremities and having a bore extending therethrough from the distal extremity to the proximal extremity, said hand-held endoscopy device having a handle assembly adapted to be grasped by the human hand, operable tool means removably mounted in said bore of the device and having a proximal portion thereof extending out of the proximal extremity permitting the same to be grasped by the hand to aid in inserting the operable tool means into the bore in the device and removal of the operable tool means from the bore of the device, said operable tool means including tool parts and an actuation mechanism for operation of the tool parts, said operable tool means and said handle assembly including cooperative means for establishing a substantially fluid-tight seal in said bore between the handle assembly and said operable tool means and hand-operated means carried by the handle assembly and connected between the handle assembly and the operable tool means to cause operation of the tool parts of the operable tool means.

7. An assembly as in claim 6 together with an adapter removably and rotatably secured to said operable tool means, said operable tool means having a bore therein in communication with the bore in the device, said adapter having a bore therein in communication with the bore in said operable tool means, means carried by said operable tool means for establishing a fluid-tight connection between the bore in said operable tool means and the adapter.

8. An assembly as in claim 7 further including switch means carried by the device for causing a liquid to be delivered to the bore in said device or alternatively to provide a vacuum to the bore in said device.

9. An assembly as in claim 7 further including switch means carried by the device for supplying electrical energy to the operable tool means to perform electrocautery operations and electrical cable means carried by the adapter and connected to said switch means.

14. A device as in claim 6 wherein one of said tool parts is provided with a hook-like portion.

15. In a method for performing a medical procedure in a patient by the use of a hand-held endoscopy device having a bore extending therethrough and a plurality of surgical tools, introducing the endoscopy device into the patient, introducing one of the surgical tools through the bore in the endoscopy device and performing electrocautery operations during the time that the tool is in place in the hand-held endoscopy device, removing the tool after the medical procedure has been completed and thereafter removing the hand-held endoscopy device from the patient.

16. A surgical tool for use with a hand-held endoscopy device comprising an elongate tubular member having proximal and distal extremities, first and second jaw members pivotally mounted on the distal extremity of said elongate tubular member, means carried by the elongate tubular member for moving the first and second jaw members between open and closed positions, said first and second jaw members being formed of metal and molded coverings formed on the said jaw members formed of a durable hard plastic material and having serrations therein.

17. A tool as in claim 16 wherein said plastic material is a polymeric material.

18. A tool as in claim 16 wherein said covering is formed to provide spaces therebetween to expose the metal of the jaws so that the tool can be utilized for electrocautery.

19. A tool as in claim 18 wherein said serrations extend transversely of the jaws and wherein said coverings are formed to provide an elongate space extending longitudinally of the jaws.
