Auxiliary device in cerebrovascular interventional operation

Abstract

The invention relates to the field of medical equipment, in particular to an auxiliary device in a cerebrovascular interventional operation. The auxiliary device comprises a positioning seat, a puncture positioning hole is formed in the middle of the top end of the positioning seat, a cold compress ring is fixed at the bottom end of the puncture positioning hole in a clamped manner, an upward inclined slope from the inside to the outside is arranged on the side wall of the upper end of the puncture positioning hole, an annular rotating groove is arranged, around the top end of the slope, at the top end of the positioning seat, the annular rotating groove is rotationally connected with an annular rotating disc, the top end of the annular rotating disc is fixedly connected with an annular support, the rear end of the annular support is provided with a locking mechanism, an arc-shape support stretching across the annular support is fixedly connected with the rear side of the top end of the annular support, the upper side of the front end of the annular support is provided with a first arc-shape sliding chute. The invention provides the auxiliary device in the cerebrovascular interventional operation which can accurately control an orientation and a needle insertion angle of a femoral artery puncture, and meanwhile, can well fix a puncture needle and a puncture catheter.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary device in cerebrovascular interventional operations. Background technique [0002] Cerebral endovascular interventional therapy utilizes catheter operation technology, with the support of digital subtraction angiography (DSA system) under computer control, to diagnose and treat lesions involving the inner blood vessels of the nervous system. Cerebrovascular interventional technology is a newly developed method to prevent and treat cerebrovascular diseases. Compared with traditional cerebrovascular disease treatment methods, it has certain advantages, and has changed the traditional mode of diagnosis and treatment of cerebrovascular diseases. With the rapid development of science and technology, cerebrovascular interventional surgery has better accuracy and trauma Small, so that the effect of surgical treatment has been significantly improved. [0003] The devices...

AI Technical Summary

Problems solved by technology

[0003] The devices used to assist cerebrovascular intervention in the prior art are often unable to assist the puncture of the femoral artery without precise control of the orientation of the puncture and the angle of the needle, and at the same time the puncture needle and the puncture catheter cannot be well punctured. Fixed, the catheter is easy to move inside the femoral artery, which affects the effect of cerebrovascular interventional therapy
