Abstract

There is provided a forcepts providing for positive and rapid ligation in surgery. The forceps comprises a manual actuator, a grasping members connected to the actuator through a body member and including two grasping members adapted to open or close in response to the corresponding action of the actuator, and a suture guide stationary with respect to the body member or either one of the grasping members, the suture guide being adapted to engage a suture and guide it to a space within reach of the grasping members.

Claims

1. A forceps comprising

a manual actuator,

a grasping means operatively connected to said actuator to open and close in response to an action of said actuator, and

a suture guide having an opening facing a grasping plane traced by the opening and closing of said grasping means and adapted to engage a suture and guide said suture to a space such that said suture can be grasped by said grasping means.

2. The forceps according to claim 1 wherein said suture guide comprises

an arm member and

a ring member rigidly secured to a forward end of said arm member for passage of said suture therethrough.

3. The forceps according to claim 2 wherein said ring member comprises a closed ring.

4. The forceps according to claim 3 wherein:

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of a body member, and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

5. The forceps according to claim 2 wherein said ring member has a suture inlet defined by resiliently splayable edges on its circumference to radially admit said suture.

6. The forceps according to claim 5 wherein:

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of a body member, and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

7. The forceps according to claim 2 wherein

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of a body member and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

8. The forceps according to claim 1 wherein said grasping means is directly connected to said actuator.

9. The forceps according to claim 1 wherein said grasping means is connected to said actuator through a body member.

10. A forceps comprising

a manual actuator,

a grasping means operatively connected to said actuator through a body member and having two grasping members adapted to open and close in response to an action of said actuator, and

a suture guide stationary with respect to said body member and having an opening facing a grasping plane traced by the opening and closing of said grasping means and adapted to engage a suture and guide said suture into a space such that said suture can be grasped by said grasping means.

11. The forceps according to claim 10 wherein said suture guide comprises

an arm member and

a ring member rigidly secured to a forward end of said arm member for passage of said suture therethrough.

12. The forceps according to claim 11 wherein said ring member comprises a closed ring.

13. The forceps according to claim 12 wherein:

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of said body member, and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

14. The forceps according to claim 11 wherein said ring member has a suture inlet defined by resiliently splayable edges on its circumference to radially admit said suture.

15. The forceps according to claim 14 wherein:

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of said body member, and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

16. The forceps according claim 11 wherein

said grasping plane traced by said grasping means is angled with respect to a longitudinal axis of said body member and

said ring member is disposed on the same side as said actuator with respect to the position of said grasping means.

17. A forceps comprising

a manual actuator,

a grasping means operatively connected to said actuator and having two grasping members adapted to open and close in response to an action of said actuator, and

a suture guide stationary with respect to one of said grasping members and having an opening facing a grasping plane traced by the opening and closing of said grasping means and adapted to engage a suture and guide said suture into a space such that said suture can be grasped by said grasping means.
