Cerebrovascular intervention puncture positioning device for neurological intervention

Abstract

The invention discloses a cerebrovascular intervention puncture positioning device for neurological intervention. The device comprises a circular ring, the inner surface of the circular ring is provided with four threaded concave grooves, the inner surface of each threaded concave groove is in threaded connection with a first threaded rod, and the first threaded rod is in rotated connection with an extrusion block away from one end of the circular ring. According to the invention, the circular ring is fixed on the patient's head by rotating the first threaded rod, then rotating cylinders are rotated to rotate an arc-shaped plate to the puncture position, the positions of rotating shafts and the rotating cylinders are locked, a I-shaped block is pushed to move along a sliding through-hole to the puncture position, the position of the I-shaped block on the arc-shaped plate is locked, rotating plates are rotated, the rotating plates are provided with steel wires in a wound mode to pull aball to rotate in a incomplete spherical through-hole, the rotation of the rotating plates is locked after adjusting the angle of a plug-in through-hole, and then a catheter is connected to a punctureinstrument at the puncture site by passing through the ball through the plug-in through-hole, which achieves the effects of fixing the catheter and adjusting the angle of the catheter from multiple angles.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a cerebrovascular intervention puncture positioning device for nerve intervention. Background technique [0002] At present, when performing cardiovascular and cerebrovascular interventional treatment for patients, most of them use a puncture needle to directly pierce the blood vessel, then remove the syringe, and then insert the catheter. Since the catheter is relatively long, it needs to be fixed, usually by sticking it with medical adhesive tape. However, this fixing method is not stable enough, and the fixing angle is difficult to adjust, which makes it inconvenient to use and affects the therapeutic effect, and needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a cerebrovascular interventional puncture positioning device for nerve intervention, which has the advantages of fixing the catheter and a...
