Abstract

A gutclamper includes two hard rod-like bodies having flexible belts on one ends, a joint at which the rod-like bodies are joined, and at least one through hole made in one of the belts. The gut tract is clipped by using the two hard rod-like bodies and the joint as a pivot. By clipping the gut tract by side surfaces of the rod-like bodies, it can be clipped while the width of the gut is pressed and widened, so that the gut is prevented from being excessively clamped and torn. In addition, the two rod-like bodies are made different in length from each other, a through hole is made in the belt connected to the shorter rod-like body, and the tip end of the longer rod-like body is fit into the through hole and locked, so that reliable clipping is realized without an excessive burden being placed on an operator.

Claims (23)

1. A gut clamp comprising:

first and second rigid and elongated straight rods, each having a proximal end and a distal end, wherein the first rod is shorter than the second rod;

first and second flexible and elongated belts, each having a proximal end and a distal end, wherein the proximal ends of the first and second belts are fixed to the first and second rods, respectively, and the first belt is fixed to the first rod and the second belt is fixed to the second rod, respectively;

a pivot joint at which the first and second rods are joined, wherein the pivot joint is located at the proximal ends of the first and second rods; and

at least one through hole made in the first belt, wherein

the rods extend longitudinally between the pivot joint and the proximal ends of the belts,

by inserting the distal end of the second belt into the through hole, the two rods clip an object by using the pivot joint as a pivot,

a distance from the pivot joint to the through hole is approximately the same as the longitudinal length of the second rod, and

by inserting a whole of the second belt entirely through the through hole, the distal end of the second rod can be fitted in the through hole and locked to transition the gut clamp from an unclamped position to a clamped position,

wherein the distal end of the second belt is tapered so that the second belt is easily inserted in the through hole, and

wherein the gut clamp is released from the clamped position by pulling the first belt and deforming the through hole into an oval shape to release the distal end of the second rod from the through hole.

2. The gut clamp according to claim 1 , wherein the surfaces of the rods are covered by covers made of a flexible resin.

3. The gut clamp according to claim 2 , wherein the belts, covers, and pivot joint are integrally molded by using the resin.

4. The gut clamp according to claim 1 , wherein the material of the rods is a metal.

5. The gut clamp according to claim 1 , wherein the material of the rods is a hard resin.

6. The gut clamp according to claim 1 , wherein the sectional shape of the rods is circular, oval, or polygonal.

7. The gut clamp according to claim 1 , wherein the lengths of the rods are 30 to 70 millimeters.

8. The gut clamp according to claim 1 , wherein the length difference between the first and second rods is 3 to 7 millimeters.

9. The gut clamp according to claim 1 , wherein at least one projection is provided on a part of the second belt so that the second belt resists escaping from the through hole after the second belt is inserted in the through hole.

10. The gut clamp according to claim 1 , wherein a serrated portion is formed on a part of the second belt so that the second belt resists escaping from the through hole after the second belt is inserted in the through hole.

11. The gut clamp according to claim 1 , wherein the color of the belts is a complementary color of red.

12. The gut clamp according to claim 11 , wherein the colors of the belts are different from each other.

13. The gut clamp according to claim 1 , wherein the length of the first belt is shorter than that of the second belt.
