AI Technical Summary

Technical Problem

Existing clamping devices have a large radial dimension of the sleeve, which causes discomfort when inserted into the patient and makes it difficult to effectively clamp large wounds.

Method used

A traction-type clamping device is designed, which adopts an avoidance groove structure to reduce the radial dimension of the clamping component, and achieves the switching between the clamping state and the opening state through the cooperation of the conversion component and the movable arm, which is suitable for clamping large wounds.

Benefits of technology

It enables the clamping component to move normally within a small radial dimension, effectively clamping large wounds, reducing discomfort for the patient, and improving clamping efficiency.

Abstract

一种牵拉式夹闭装置及其夹闭结构，其用于驱动活动臂相对固定臂张开和闭合的转换件在运动过程中，具有朝向夹闭组件的装配腔的腔壁的运动轨迹。本结构中装配腔的腔壁设有避让槽，该避让槽位于转换件的运动轨迹之上，以使得转换件的一部分能够伸入至避让槽内，因此夹闭组件可以较小的径向尺寸，实现转换件的正常运动。
