Puncture assisting device

Abstract

The invention discloses a puncture assisting device. The device comprises a rotating plate and a fixed plate, the rotating plate rotates around one axis perpendicular to the side wall of the fixed plate; a first angle indicating device used for indicating the opening and closing angle of the rotating plate and the fixed plate is arranged between the rotating plate and the fixed plate, a needle guide device is rotationally connected to the rotating plate, and a second angle indicating device used for indicating the relative rotating angle of the rotating plate and the needle guide device is arranged between the rotating plate and the needle guide device. The medical staff adjusts the opening and closing angle between the rotating plate and the fixed plate and the relative rotating angle between the needle guide device and the rotating plate according to the actual clinical situation, then the medical staff pushes and inserts a puncture needle into the body of the patient, and the puncture assisting device guides the puncture needle. According to the puncture assisting device, the stability and the accuracy of a puncture angle are ensured to a great extent when a clinician performs puncture, and the probability of puncture failure caused by misoperation can be reduced. The invention is applied to the technical field of medical instruments.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture assisting device. Background technique [0002] Common vascular interventional catheters, such as central venous catheters, hemodialysis catheters, PICCs, catheter sheaths, etc., are generally inserted by Seldinger puncture method: the basic principle of Seldinger is to insert a puncture needle into the catheter before placing the catheter. In the blood vessel, a guide wire is used to establish a tube channel, and then the catheter is sent into the blood vessel along the guide wire. [0003] In clinical catheterization, due to differences in puncture sites, patients' own conditions, and doctor's operating habits, the angle and direction of puncture also need to be adjusted according to the actual situation. At present, when clinicians perform puncture operations, they generally directly insert blood vessels directly by controlling the puncture angle and direct...

AI Technical Summary

Problems solved by technology

At present, when clinicians perform puncture operations, they generally directly insert blood vessels directly by controlling the puncture angle and direction with their hands. Doctors operate more based on their own experience. For doctors with insufficient clinical experience, there may be certain errors in each operation, which affects Puncture success rate and stability
