Embodiment 1

[0029] like Figure 2 to Figure 3 As shown, it is a medical blood vessel clip provided in the first embodiment of the present application, and the medical blood vessel clip includes: a hard clamping part 1 , a soft buffer part 2 and a clamping radius adjusting part 3 .

[0030] Wherein, the hard clamping part 1 is in a cylindrical shape, and when the blood vessel is clamped by the hard clamping part 1, the surrounding force of the blood vessel can be made uniform, and the damage to the blood vessel can be avoided during the process of clamping the blood vessel. .

[0031] The circumferential direction of the hard clamping part 1 is provided with an opening, and when the blood vessel is clamped, the blood vessel can be sent into the inside of the hard clamping part through the opening, so that the hard clamping part 1 can be used to Blood vessels are clamped. The material of the hard clamping part 1 can be selected from materials such as medical hard plastic or medical stainl...

Embodiment 2

[0043] like Figure 4 to Figure 5 As shown, a medical vascular clip provided in the second embodiment of the present application includes: a hard clamping part 1 , a soft buffer part 2 and a clamping radius adjusting part 3 .

[0044] Wherein, the hard clamping part 1 is in a cylindrical shape, and an opening is provided in the circumferential direction of the hard clamping part 1 for blood vessels to enter; the soft buffer part 2 is arranged on the hard clamping part 1. The inner side of the clamping part 1; the clamping radius adjusting part 3 is arranged on the hard clamping part 1, and the clamping radius adjusting part 3 is connected to the area at both ends of the opening of the hard clamping part 1 touch.

[0045] Specifically, the hard clamping part 1 is tapered as a whole, including a thick end 18 and a thin end 19; the outer diameter of the hard clamping part 1 gradually The diameter of each part inside the hard clamping part 1 is the same.

[0046] The outer peri...

Embodiment 3

[0055] like Image 6 As shown, a medical blood vessel clamp provided in the third embodiment of the present application is different from the second embodiment in that openings are provided in the circumferential direction of the clamping radius adjustment member 3; the clamping radius adjustment A threaded hole 23 is arranged on the peripheral surface of the member 3, and a fastening nut 24 is arranged in the threaded hole 23 .

[0056] The specific usage method of the medical vascular clip of the present embodiment is as follows:

[0057] During use, first remove the clamping radius adjusting member 3 or open the opening of the clamping radius adjusting member 3, and then open the openings of the hard clamping part 1 and the soft buffer part 2, Place the required clamping blood vessel in the columnar hole 20 of the soft cushioning part 2. After placing the blood vessel, gently rotate the clamping radius adjustment member 3 until it reaches the required tightness. The rotat...

Abstract

An embodiment of the invention discloses a medical vascular clamp which comprises a hard clamping portion, a soft buffering portion and a clamping radius adjusting member. The hard clamping portion iscylindrical, an opening is formed in the circumferential direction of the hard clamping portion, the soft buffering portion is arranged on the inner side of the hard clamping portion, and the clamping radius adjusting member is arranged on the hard clamping portion and used for adjusting clamping radius of the hard clamping portion. During a surgery, a blood vessel is clamped through the medicalvascular clamp, the soft buffering portion contacts with the blood vessel, and contraction degree of the hard clamping portion is adjusted through the clamping radius adjusting member so as to realizeclamping of the blood vessel. The hard clamping portion is cylindrical, so that four sides of the blood vessel are stressed more uniformly, and damage to the blood vessel is reduced.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a medical blood vessel clip. Background technique [0002] In surgery, in order to carry out the operation smoothly, it is often necessary to clamp the main blood vessels with the help of some medical instruments, so as to reduce the outflow of blood and avoid excessive blood loss of the patient during the operation. [0003] At present, the medical devices clinically used to clamp blood vessels to reduce blood outflow mainly include sutures, vascular clamps and vascular clamps. Among them, the use of sutures to ligate blood vessels has the advantages of small space occupation, firm fixation of blood vessels, and little damage to blood vessels. However, using sutures to ligate blood vessels is more complicated. Therefore, in surgical During the operation, blood vessel clamps or blood vessel clamps are often used to clamp blood vessels. like figure 1 As shown,...
