Problems solved by technology

In many studies, the design of the catheter operation robot device at the surgical site is based on the friction roller method, which is easy to cause damage to the catheter, and the damaged catheter may also cause damage to the blood vessel. At the same time, there is a propulsion error in the friction push itself
Acquisition and feedback of catheter axial operating force has become an important point, but catheter rotational torque is often neglected
At the same time, in the detection of the force on the front end of the catheter, the detection of the contact force on the side wall of the catheter does not almost involve or only detects whether there is a contact force and its magnitude, without distinguishing the direction of the force

Abstract

A master slave minimal invasive blood vessel interventional surgical assistant system is characterized in that the system is formed by a master side part and a slave side part; a work method of the system comprises detection, transmission, processing and action of signals; the system has the advantages that when the information transmitted in the catheter operation is real-time and accurate and the surgery safety can be effectively improved; real-time detection on abnormal operation and system faults is realized and the system safety is effectively ensured; the propelling error is low; a contact force sensor at the side wall of a catheter can be used for detecting the size of a contact force and distinguishing the stress direction.

Description

(1) Technical field: [0001] The invention belongs to the technical field of medical equipment, and in particular is a master-slave minimally invasive vascular interventional operation auxiliary system, which is especially suitable for angiography, removal of thrombus or foreign body, treatment of tumor or vascular malformation, dissolution of thrombus, and the like. (two) background technology: [0002] Cardiovascular and cerebrovascular diseases have become one of the three major causes of death in humans, seriously threatening human health. Vascular diseases mainly include vascular tumors, thrombosis, vascular malformations, vasoconstriction, and vascular sclerosis. Catheter interventional surgery is currently the most effective method for treating cardiovascular and cerebrovascular diseases. Compared with "open" surgery, it has the advantages of less trauma, safety, faster postoperative recovery, and fewer complications. However, there are also some problems in tradition...
