Abstract

A trocar gripper with means for facilitating suturing of an insertion site thereof. The gripper includes a tubular housing provided with gripping structure for gripping a trocar guide tube. The housing is also provided with structure for fixing the axial position of the housing within an incision in a patient. A pair of opposed openings are formed through the tubular wall of the housing into the axial bore thereof. A plug is provided which may be inserted the axial bore of the housing, and fixed in place by the gripping structure of the housing. The plug is provided with an elastomeric seal which engages the surface of the axial bore through the housing. Radially outwardly extending lugs are formed on a second end of the plug. The plug is provided with a pair of opposed, longitudinally extending recesses formed in the outer surface thereof. Each recess extends from the second end of the plug to a point adjacent the associated opening through the wall of the housing. An axial bore may be provided through the plug to permit the insertion of laparoscopic surgical instruments with the plug in place.

Claims

1. A device for facilitating suturing of laparoscopic surgery puncture wounds comprising:

a hollow housing including a wall having an opening formed therethrough; and

a plug disposed within said hollow housing and including an outer surface having a recess formed therein, said recess having an end which is inclined toward said outer surface and aligned with said opening formed through said hollow housing.

2. The device for facilitating suturing defined in claim 1 wherein said plug includes a first end and a second end, said recess extending between said second end and a point intermediate said first end and said second end.

3. The device for facilitating suturing defined in claim 1 further including means for positioning said plug at a predetermined position within said opening of said housing.

4. The device for facilitating suturing defined in claim 3 wherein said means for positioning said plug includes a lug extending radially outwardly from said plug and a locating notch formed in said housing.

5. The device for facilitating suturing defined in claim 1 further including a gripping member coupled to said housing for selectively securing said plug within said opening of said housing.

6. The device for facilitating suturing defined in claim 1 wherein said plug includes an axial bore therethrough.

7. The device for facilitating suturing defined in claim 6 further including a flap coupled to said plug for covering said axial bore through said plug.

8. The device for facilitating suturing defined in claim 6 wherein said axial bore is in communication with said recess.

9. A device for facilitating suturing of laparoscopic surgery puncture wounds comprising:

a tubular housing having a first end, a second end, and a wall defining an axial bore, said wall further defining a pair of opposed openings through said wall into said axial bore intermediate said first end and said second end;

a plug having a first end and a second end adapted to be inserted into said housing for selectively sealing a portion of said axial bore of said housing, said plug having an outer surface and defining a pair of opposed, longitudinally extending recesses formed in the outer surface of said plug, said recesses extending between said second end and a point intermediate said first end and said second end; and

means for positioning said plug at a predetermined position within said axial bore of said housing, whereby when said plug is positioned at said predetermined position within said axial bore of said housing, each of said axially extending recesses in said plug extends from a point radially inward of a respective one of said opening through said wall of said tubular portion of said housing to said second end of said plug.

10. The device for facilitating suturing defined in claim 9 further including a gripping member coupled to said housing for selectively securing said plug within said opening of said housing.

11. The device for facilitating suturing defined in claim 9 wherein said plug includes an axial bore therethrough.

12. The device for facilitating suturing defined in claim 11 further including a flap coupled to said plug for covering said axial bore through said plug.

13. The device for facilitating suturing defined in claim 11 wherein said axial bore is in communication with each of said recesses.

14. The device for facilitating suturing defined in claim 9 wherein each of said recesses is outwardly inclined from said second end of said plug.

15. The device for facilitating suturing defined in claim 9 wherein said means for positioning said plug includes a lug extending radially outwardly from said plug and a locating notch formed in said housing.

16. A device for facilitating suturing of laparoscopic surgery puncture wounds, comprising:

a tubular housing having a first end, a second end, and a wall defining an axial bore, said wall further defining a pair of opposed openings through said wall into said axial bore intermediate said first end and said second end;

a plug adapted to be inserted into said housing for selectively sealing a portion of said axial bore of said housing, said plug having an outer surface and defining a pair of opposed, longitudinally extending recesses formed in the outer surface of said plug, said plug having an axial bore therethrough; and

a flap coupled to said plug for coveting said axial bore through said plug.

17. The device for facilitating suturing defined in claim 16 wherein said axial bore is in communication each of said recesses.

18. The device for facilitating suturing defined in claim 16 wherein said plug includes a first end and a second end, each of said recesses extending between said second end and a point intermediate said first end and said second end.

19. The device for facilitating suturing defined in claim 16 further including means for positioning said plug at a predetermined position within said axial bore of said housing.

20. The device for facilitating suturing defined in claim 19 wherein said means for positioning said plug includes a lug extending radially outwardly from said plug and a locating notch formed in said housing.

21. A device for facilitating suturing of puncture wounds including a conical body having a distal end for inserting into a puncture wound, a proximal end, an outer surface having a helical thread formed thereon, and a pair of opposed recesses formed in said outer surface extending from said proximal end to a point intermediate said distal and proximal ends.
