Problems solved by technology

[0004] However, it is found during the use of the current hemostatic clip that after the two clamp arms are closed, the clamping force between the two clamp arms is insufficient, and it is easy to fall off, which makes the ligation of the pipeline tissue and the effect of hemostasis Affected, there are certain defects and risks in the use of security

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 2 As shown, the strong anti-off hemostatic clip in this embodiment includes a first clip arm 1 and a second clip arm 2, similar to the existing hemostatic clip, the first clip arm 1 and the second clip arm 2 are integrally connected , roughly V-shaped before closing;

[0018] Of course, the first clamping arm 1 and the second clamping arm 2 can also be movably connected by a hinge.

[0019] The mating surfaces of the first clamping arm 1 and the second clamping arm 2 have an arc-shaped structure that matches each other, and a fastening structure is provided between the first clamping arm 1 and the second clamping arm 2 so that they can be tightly closed and fastened together. After being combined, the mating surfaces of the first clamping arm 1 and the second clamping arm 2 are closely attached to each other and closed...

Abstract

The invention relates to a powerful anti-disengaging hemostatic clip. The powerful anti-disengaging hemostatic clip comprises a first clip arm and a second clip arm connected with the first clip arm. The first clip arm and the second clip arm have matched arc-shaped structures, a buckling structure is arranged between the first clip arm and the second clip arm, and the first clip arm and the second clip arm can be tightly buckled together. An elastic deformation body arching towards one side of the second clip arm is arranged on the folding face of the first clip arm, the two ends of the elastic deformation body are integrally connected with the first clip arm, and a hollowed-out part is formed between the elastic deformation body and the first clip arm. The elastic deformation body is additionally arranged, the portion between the first clip and the second clip arm has effective elastic deformation capacity, the hollowed-out part between the elastic deformation body and the first clip arm is a deformation region of the elastic deformation body, tight clamping force to the pipeline structure is most directly and effectively improved, ligation and hemostasis effects are guaranteed, and the surgical safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a strong anti-off hemostatic clip, which is especially suitable for ligation or hemostasis in minimally invasive operations. Background technique [0002] The hemostatic clip is a surgical instrument that is frequently used in surgical operations. It is used for ligation or hemostasis of pipeline tissues, and is especially suitable for ligation and hemostasis in small-field minimally invasive operations such as laparoscopic surgery. Such as figure 1 As shown, it is a hemostatic clip structure of polymer materials commonly used in surgical operations at present, which mainly includes a first clamp arm 1', a second clamp arm 2', a first clamp arm 1', and a second clamp arm 2 connected integrally. 'both have a certain radian, and the radians of the two coincide to seamlessly close each other. The connection of the first clamp arm 1' and the second clamp arm 2' has a cre...
