Abstract

A surgical instrument having a body, a tissue engaging and manipulating finger, and first structure for mounting the finger to the body. The finger has second structure thereon at first and second spaced locations to allow tissue engaged thereby to bridge the first and second spaced locations to allow a needle to be conveniently directed into a tissue engaged by the finger.

Claims

1. A surgical instrument comprising:

a body;

a tissue engaging and manipulating finger; and

first means for mounting the finger to the body,

said finger having second means thereon including first, second and third projections having unjoined free ends which are in fixed, spaced relationship to allow tissue engaged thereby to bridge the first, second and third projections to allow a needle to be directed into a tissue engaged by the finger,

wherein the finger has a body made from a first material and there is a second material that is different than the first material on the finger between at least two of the projections to allow a needle directed through tissue engaged by the finger to be directed against the second material.

2. The surgical instrument according to claim 1 wherein the second material is a resilient material that is penetrable by a suturing needle.

3. The surgical instrument according to claim 2 wherein the resilient material is rubber.

4. A surgical instrument comprising:

a body;

a tissue engaging manipulating finger; and

first means for mounting the finger to the body,

said finger having second means thereon including first, second and third projections having unjoined free ends which are in fixed, spaced relationship to allow tissue engaged thereby to bridge the first, second and third projections to allow a needle to be directed into tissue engaged by the finger,

wherein there is a convex surface on the finger to deflect a needle passed through tissue engaged by the finger away from the finger.

5. A surgical instrument comprising:

a body;

a tissue engaging and manipulating finger; and

first means for mounting the finger to the body,

said finger having second means thereon including first, second and third projections having unjoined free ends which are in fixed, spaced relationship to allow tissue engaged thereby to bridge the first, second and third projections to allow a needle to be directed into a tissue engaged by the finger,

wherein the first means comprises means for mounting the finger to the body for movement relative thereto between first and second positions.

wherein the first means comprises means for mounting the finger to the body for pivoting movement about a first axis between the first and second positions.

6. The surgical instrument according to claim 5 including means on the body for repositioning the finger selectively between said first and second positions from a location remote from said finger.

7. The surgical instrument according to claim 5 wherein the first means includes means for removably connecting the finger to at least a portion of the body.

8. The surgical instrument according to claim 5 including means on the body for biasing the finger towards one of the first and second positions.

9. The surgical instrument according to claim 5 including means on the body for releasably maintaining the finger in each of the first and second positions.

10. The surgical instrument according to claim 5 including means on the body for releasably maintaining the finger in a third position between the first and second positions.

11. A surgical instrument comprising:

a body;

a tissue engaging and manipulating finger; and

first means for mounting the finger to the body,

said finger having second means thereon including first, second and third projections having unjoined free ends which are in fixed, spaced relationship to allow tissue engaged thereby to bridge the first, second and third projections to allow a needle to be directed into a tissue engaged by the finger,

wherein the first means comprises means for mounting the finger to the body for movement relative thereto between first and second positions,

wherein the first means includes an elongate rod, an actuator, means for mounting the actuator to the body for movement between actuated and released positions, means cooperating between the elongate rod and actuator for moving the elongate rod between first and second positions as the actuator moves between the actuated and released positions, and means cooperating between the elongate rod and finger for moving the finger between the first and second positions as an incident of the elongate rod moving between its first and second positions.

12. The surgical instrument according to claim 11 wherein the body includes a gripping portion that can be grasped by the hand of a user in such a manner that the actuator is accessible to and operable by a finger on the hand of a user grasping the surgical instrument.

13. The surgical instrument according to claim 12 wherein the body has a pistol-type shape with an elongate body portion and a gripping portion extending transversely to the length of the elongate body portion.

14. A method of manipulating body tissue through a cavity bounded by the tissue, said method comprising the steps of:

providing a surgical instrument having an elongate body with a finger at an end thereof, said finger having a length extending transversely to the length of the body and first, second, and third projections having unjoined free ends which are in fixed, spaced relationship to allow tissue engaged thereby to bridge and be supported by the first, second and third projections;

directing the finger into the tissue cavity and bearing the first, second and third projections on the finger against the tissue to stabilize the tissue; and

directing a needle into the tissue stabilized by the finger between at least two of the projections.

15. The method of manipulating body tissue according to claim 14 wherein the step of directing a needle into the tissue comprises the step of directing a needle through a vaginal wall.

16. The method of manipulating body tissue according to claim 15 including the step of attaching the vaginal wall to a fixed pelvic structure by directing the needle into a fixed pelvic structure after the needle is directed into tissue engaged by the finger.

17. The method of manipulating body tissue according to claim 16 including the step of lifting the vaginal wall with the finger to facilitate connection of the vagina to a fixed pelvic structure.

18. The method of manipulating body tissue according to claim 16 wherein the step of providing a surgical instrument includes the step of providing a resilient material on the finger and including the step of directing the needle into the resilient material after it is directed into the tissue stabilized by the finger.

19. The method of manipulating body tissue according to claim 16 wherein the step of providing a surgical instrument comprises the step of providing a surgical instrument wherein the step of providing a surgical instrument comprises the step of providing a surgical instrument wherein the free ends on the first, second and third projections are spaced relative to each other so that they do not reside in a single line.

20. The method of manipulating body tissue according to claim 14 including the step of varying the orientation of the finger relative to the body from a first orientation, wherein the length of the finger is substantially aligned with the length of the body, to a second orientation, wherein the length of the finger extends transversely to the length of the body, after the finger is directed into the cavity.
