Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vascular surgical instruments and relates to a multi-point clamping vascular clamp. Background Art
[0002] Vascular clamps are used to clamp blood vessels, which facilitates suturing and clamping of blood vessels during surgery. Currently, most vascular clamps are two hinged single-arm clamp structures with a very small clamping surface. In order to avoid damaging the blood vessels, a rubber hose is usually put on the clamp head of the vascular clamp. However, this can easily cause the rubber hose to fall off and remain in the tissue. In addition, when clamping the artery, single-point clamping sometimes fails to achieve a hemostatic effect. Utility Model Content
[0003] The purpose of the utility model is to provide a multi-point clamping blood vessel clamp to solve the above problems in the prior art. The technical problem to be solved by the utility model is how to increase the clamping surface and improve the clamping effect.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a multi-point clamping blood vessel clamp, characterized in that it includes two clamp arms hinged by a pin shaft, the clamp arm includes a clamp head and a clamp handle respectively located at both ends of the hinge point, the clamp head has two clamp arms parallel to each other, an elastic sheet is connected between the two clamp arms, the middle part of the elastic sheet is convex, and the elastic sheets of the two clamp arms are symmetrically distributed.
[0005] Furthermore, the pliers handle is provided with a positioning rack.
[0006] Furthermore, the elastic sheet is detachably connected between the two clamping arms.
[0007] When in use, you can choose to install the elastic sheet or not. When using the elastic sheet, the blood vessel is clamped with two rigid points and one flexible point, that is, the two sets of clamp arms are rigid clamping points, and the point between the two elastic sheets is a flexible clamping point. Since the elastic sheet has elastic restoring force, the pressing force on the blood vessel during clamping is relatively smooth and gentle. The three-point clamping shares the clamping force on the blood vessel, reduces the damage to the blood vessel by clamping and achieves the clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the multi-point clamping vascular clamp includes two clamp arms hinged by a pin shaft, and the clamp arms include a clamp head 1 and a clamp handle 2 respectively located at both ends of the hinge point. The clamp head 1 has two clamp arms 3 parallel to each other, and an elastic sheet 4 is connected between the two clamp arms 3. The middle part of the elastic sheet 4 is convex, and the elastic sheets 4 of the two clamp arms are symmetrically distributed.
[0014] The clamp handle 2 is provided with a positioning rack 5 for positioning the swing angle, that is, locking the clamp.
[0015] The elastic sheet 4 is detachably connected between the two clamping arms 3. The clamping arms are provided with slots, and the two ends of the elastic sheet are arranged in the slots.
[0016] When in use, you can choose to install the elastic sheet 4 or not. When using the elastic sheet 4, the blood vessel is clamped with two rigid points and one flexible point, that is, the two groups of clamp arms are rigid clamping points, and the area between the two elastic sheets 4 is a flexible clamping point. Since the elastic sheet 4 has elastic restoring force, the pressing force on the blood vessel during clamping is relatively smooth and gentle. The three-point clamping shares the clamping force on the blood vessel, reduces the damage to the blood vessel caused by clamping, and achieves the clamping effect.
[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
