Stent length simulation device applied to coronary intervention operation

Abstract

The invention discloses a stent length simulation device applied to a coronary artery interventional operation, and relates to the technical field of coronary arteries, the stent length simulation device comprises a lead, the outer wall of the lead is slidably connected with a sliding block, and the outer wall of the sliding block is provided with a measurement adaptation mechanism. By arranging the measurement adaptation mechanism, a plurality of small sliding blocks can be automatically attached to a protective film to achieve attachment to the inner wall of a blood vessel, the contraction condition of an affected part of the inner wall of the blood vessel can be accurately simulated, automatic printing and dyeing are conducted through pigment, accurate judgment can be conducted according to marks of the pigment position, and the accuracy of the measurement is improved. Therefore, the pigment can be pushed out only after the small sliding block is tightly attached to the inner wall of the blood vessel, the pigment dyeing accuracy is further improved, long-term repeated use can be achieved, the one-time cleaning effect can be achieved by replacing the protective film, the economic benefits are greatly improved, a large amount of cost and data are saved, and the production efficiency is improved. The environment is protected.

Description

technical field [0001] The invention relates to the technical field of coronary arteries, in particular to a stent length simulation device applied to cardiac coronary intervention operations. Background technique [0002] The shape of the heart is like an inverted, slightly flattened cone. If it is regarded as a head, the coronary artery located on the top of the head and almost surrounding the heart is like a crown, which is the origin of its name. Coronary arteries are the arteries that supply blood to the heart. They originate in the aortic sinus at the root of the aorta, divide into two branches, and run on the surface of the heart. Using the classification principles of Schlesinger et al., the distribution of coronary arteries was divided into three types: 1. Right-dominant type; 2. Balanced type; 3. Left-dominant type. At present, before the placement of stents in coronary artery interventional surgery, the length of the affected area below 2mm is measured by a ballo...

AI Technical Summary

Problems solved by technology

At present, before the placement of stents in coronary artery interventional surgery, the length of the affected area below 2mm is measured by a balloon, but when the affected area exceeds 3mm, the measurement is prone to inaccurate situations, resulting in the occurrence of stents due to inaccurate measurement of the position of the affected area. If the length is too short, it is necessary to add a bracket, and if the length of the bracket is too long, the probability of lifting the bracket to be unloaded will occur
