In the endoscopic surgery operation, the first clamping portion 13 of the first clamping piece 10 and the second clamping portion 23 of the second clamping piece 20 cooperate with each other to clamp the bleeding tissue so as to press the bleeding tissue to stop bleeding.
By attaching the first collar 30 to the first clip 10 or the second clip 20, the first collar 30 can facilitate the medical staff to use the surgical instrument to pass through the first collar 30 for gripping. Therefore, medical personnel can stably lift the first collar 30 and the clamped tissues through the surgical instrument, the situation that the surgical field of vision is shielded by the first collar 30 and the clamped tissues is avoided, the field of vision of the endoscopic surgery is ensured, and the difficulty of surgical operation is reduced.
The hemostatic clamp further comprises a tube body 40 which comprises an extending direction, wherein the two ends of the tube body in the extending direction are provided with tube openings, and the tube openings at the two ends of the tube body are communicated to form a tube cavity. And the sliding unit is slidably arranged in the tube cavity along the extending direction and can slide from a first position to a second position.
It should be noted that the sliding unit and the pipe body in the present invention may be any conventional ones. For example, the technical solution disclosed in application No. 202010241538.7 can realize the function of the sliding unit. Therefore, the slide unit will not be described here.
The first clip 10 includes a first segment 11 and a second segment 12 arranged at an angle. The first segment 11 is connected to the sliding unit. The second clip 20 includes a third segment 21 and a second segment 12 arranged in a clip angle manner. The third segment 21 is connected to the sliding unit.
The sliding unit drives the first clip 10 and the second clip 20 to slide from the first position to the second position, the inner wall of the tube 40 limits the first section of sheet body 11 and the third section of sheet body 21, so that the first section of sheet body 11 and the third section of sheet body 21 elastically deform and approach each other, and the first section of sheet body 11 and the third section of sheet body 21 slide into the tube cavity of the tube.
Fig. 1 shows the first clip 10 and the second clip 20 in the first position, i.e. the first clip 10 and the second clip 20 are in an open, undamped state. Fig. 2 shows the first clamping piece 10 and the second clamping piece 20 in the second position, i.e. the first clamping piece 10 and the second clamping piece 20 are in the closed clamping state.
First section lamellar body 11 and second section lamellar body 12 through setting up the contained angle formula and arranging form first clamping piece 10 to and third section lamellar body 21 and fourth section lamellar body 22 that the contained angle formula was arranged form second clamping piece 20, the slip unit drives first clamping piece 10 and second clamping piece 20 by first position slip to second position, first section lamellar body 11 and third section lamellar body 21 support by the pipe wall in the body and elastic deformation, first section lamellar body 11 and third section lamellar body 21 roll back to in the lumen of body 40, second section lamellar body 12 and fourth section lamellar body 22 are close to each other and are the clamping status.
Ensures that the first and second jaws 10 and 20 can be stably closed and reliably clamp the bleeding tissue.
Prevent the collar 30 from backing into the lumen together with the second segment 12 and prevent the first collar 30 from affecting the first and second clamping portions 13, 14 to clamp tissue. Thus, the body 12 is connected to the first collar 30 at the second segment of the first clip 10. Or the fourth segment 22 of the second clip 20 is connected to the first collar 30.
The connection of the first segment 11 or the fourth segment 22 with the collar 30 ensures that the first collar 30 can be lifted by the surgical instrument and avoids the interference of the first collar 30 with the normal clamping action of the first and second clamping portions 13, 14.

Not only is the first collar 30 stable on the second segment 22 ensured, but also the connection structure of the second segment 22 and the first collar 30 is simple, and the production and the manufacture are convenient.
In addition, a second through hole may be formed in the third segment body 21 of the second clip 20. The hemostatic clamp further comprises a second sleeve ring, and the second sleeve ring is sleeved on the second through hole. The second through hole and the second collar are not shown in the figures.
The angle theta formed by the length direction of the first-stage sheet body 11 and the length direction of the second-stage sheet body 12 is 120-160 degrees. It is ensured that only the first 11 and third 21 segments are retracted into the lumen of the tube 40.
Two specific shapes for the first collar 30 are as follows.
First, the first collar 30 is annular, and the diameter of the first collar 30 is 4mm to 5 mm.
Secondly, the first collar 30 is in an elliptical ring shape, the long axis of the first collar 30 is 5-6 mm, and the short axis of the first collar 30 is 3-4 mm. Like this after the hemostatic clamp centre gripping is accomplished, swing joint's first lantern ring 30 can be attached on the second section lamellar body 12 of first clamping piece, reduces the space that first lantern ring 30 occupied in the human body, reduces the risk that the hemostatic clamp used, improves the result of use of hemostatic clamp.
Specifically, the length of the first section of the first clip 10 is 4mm to 5mm, and the length of the second section of the first clip 10 is 5mm to 6 mm. The distance between the first clamping part 13 and the second clamping part 23 is 8-12 mm.
As shown in fig. 3, the present invention further provides a hemostatic assembly, which includes two hemostatic clamps of the above embodiments, the two hemostatic clamps are disposed adjacently, and the first clamping piece of one hemostatic clamp is inserted into the first collar 30 of the other hemostatic clamp.
Like this hemostatic clamp can overlap each other and establish together, and in the operation process, surgical instruments can wear to overlap in first lantern ring 30 together, can carry and draw two hemostatic clamps in the lump, further improves the field of vision scope of operation, reduces the operation risk.
