A universal robot for interventional imaging and therapeutic surgery

Abstract

The invention relates to a general-purpose robot for interventional radiography and therapeutic surgery, which solves the problem that the existing interventional surgery robot cannot complete the two processes of interventional surgery at the same time, and detects the axial friction force of the guide wire, and solves the difficulty in installing the force detection device. , cannot meet the clinical needs, the structure of the robot in the actual operation is relatively complicated, and the volume is too large to be suitable for the actual operation environment. It realizes the general purpose of contrast surgery and therapeutic surgery, simple overall structure, good stability, adopts modular structure design, easy disassembly and assembly, small size, and is very suitable for the surgical environment. By measuring the push-pull force of the micro-force sensor at the main end, the force change of the axial friction force of the guide wire can be judged, and the operation reminder can be given to the doctor in time to protect the safety of the patient. According to the feedback value from the high-precision weighing sensor at the end, the clamping degree of the guide wire can be adjusted at any time to prevent slippage and meet the needs of the guide wire for vascular interventional surgery.

Description

technical field [0001] The invention relates to the technical field of minimally invasive vascular equipment, and more specifically relates to a universal robot for interventional imaging and therapeutic operations. Background technique [0002] The complete process of interventional surgery includes angiographic diagnosis, balloon expansion, stent placement and other treatment processes. Among them, interventional angiography is the basis for the diagnosis of cardiovascular and cerebrovascular diseases, and it is also the prerequisite for further treatment. Therapeutic surgery is a necessary step to relieve the pain. The two surgical techniques are different, and the implementation process is different. Domestic robots for interventional contrast surgery have the following problems: (1) The device is bulky, complex in structure, and not stable enough to be suitable for actual clinical operations; (2) Most robots do not have a force feedback system, which cannot guarantee t...

AI Technical Summary

Problems solved by technology

Domestic robots for interventional contrast surgery have the following problems: (1) The device is bulky, complex in structure, and not stable enough to be suitable for actual clinical operations; (2) Most robots do not have a force feedback system, which cannot guarantee the accuracy of surgery. Safety; (3) The installation and disassembly of the system is inconvenient; (4) The disinfection of the robot is cumbersome and does not meet the actual surgical needs

(5) Most robots can only perform interventional radiography or interventional therapy, and there is a lack of interventional robots that can complete radiography and treatment at the same time
