Interventional operation catheter guide wire driving mechanism

Abstract

An interventional operation catheter guide wire driving mechanism relates to medical instruments. Comprising a linear motion unit, a hollow rotating table, a wire feeding mechanism and a pipe feeding mechanism. The hollow rotating table is connected with the linear motion unit through a connecting piece, the hollow rotating table comprises a guide wire rotating platform and a catheter rotating platform, the guide wire rotating platform is vertically fixed on a linear motion unit moving platform, and the catheter rotating platform is vertically fixed at the foremost end of a linear motion unit main body; the wire feeding mechanism and the catheter feeding mechanism are located on the guide wire rotating platform and the catheter rotating platform respectively and rotate along with rotation of the hollow rotating table. The wire feeding mechanism and the catheter feeding mechanism are consistent in height and are respectively used for pushing a guide wire and a catheter; the linear motion unit cooperates with the wire feeding mechanism and the catheter feeding mechanism to drive the guide wire and the catheter to advance and retreat, and the hollow rotating table drives the guide wire and the catheter to rotate. By introducing linear driving and friction wheel hybrid driving, pushing and rotating movement of the catheter and the guide wire can be driven at the same time.

Description

technical field [0001] The invention relates to a medical device, in particular to an interventional operation catheter guide wire driving mechanism capable of simultaneously driving the catheter guide wire to push and rotate. Background technique [0002] Minimally invasive interventional surgery is "sending special instruments, physical energy or chemical agents into the human body through minimal trauma or natural channels to complete surgical operations such as inactivation, resection, repair or reconstruction of lesions, deformities, and trauma in the human body." It has the advantages that traditional surgical operations do not have, such as reducing the pain of patients, reducing the risk of infection, and reducing the difficulty of healing, and is gradually replacing traditional surgical operations with large wounds. [0003] In interventional liver surgery, the microcatheter is inserted into the human body through the blood vessel, and the catheter guide wire approa...

AI Technical Summary

Problems solved by technology

[0004] Existing interventional liver surgery requires doctors to operate manually in the X-ray environment. There are the following problems: the time of liver interventional surgery varies with the patient's condition and surgical needs In 1~3h; X-ray radiation for a long time will cause immeasurable harm to doctors

Standing for a long time and performing delicate surgical operations will bring a huge workload to doctors, cause back pain, and even cause related occupational diseases
