AI Technical Summary

Technical Problem

In current coronary artery bypass grafting procedures, the anastomosis needs to be exposed by a surgical assistant holding a blower, which increases the allocation of medical resources and labor intensity, and the field of vision is not clear enough, affecting the efficiency and safety of the operation.

Method used

A device for exposing anastomosis during coronary artery bypass grafting was designed, comprising multi-dimensional adjustment components and an exposure structure. It can accurately locate and direct airflow to expose the anastomosis, and is equipped with a camera for real-time recording, reducing the need for assistant resources and improving surgical efficiency and safety.

Benefits of technology

It achieves clear exposure of the anastomosis, reduces the need for assistant resources, improves surgical efficiency and safety, reduces labor intensity, and provides a clear field of vision and real-time recording support.

Abstract

This invention provides an anastomosis exposure device for coronary artery bypass grafting, relating to the field of anastomosis exposure, comprising: a frame; a set of spreading columns fixedly disposed at the end of the frame; a positioning component fixedly disposed at the top of the spreading columns, and a first adjustment component disposed inside the positioning component; a second adjustment component fixedly disposed inside the first adjustment component; a connecting mechanism rotatably disposed outside the second adjustment component, and an exposure structure fixedly disposed at the bottom of the connecting mechanism; through the second adjustment component, the connecting mechanism, and the exposure structure; the exposure structure can be precisely adjusted in multiple dimensions according to the actual position of the anastomosis; at the same time, the exposure structure can generate directional airflow to effectively blow away the blood and fluid accumulated around the anastomosis, creating a clear and unobstructed field of vision for the surgeon; solving the problem of blood and fluid and other bodily fluids accumulating around the anastomosis, making it difficult for the surgeon to clearly and unobstructedly observe the anastomosis.
