Manual control operation device based on vascular interventional operation training system

Abstract

The invention provides a manual control operation device based on a vascular interventional operation training system, and belongs to the technical field of medical training equipment, and the manualcontrol operation device comprises a catheter, a guide shaft, a force / moment detection mechanism and a mechanism for realizing two-degree-of-freedom motion and force tactile feedback, the force / torquedetection mechanism is used for detecting an operating force applied to the axial direction of the guide shaft and detecting an operating torque applied to the circumferential direction of the guideshaft; the force / moment detection mechanism comprises a transmission block capable of coaxially rotating with the guide shaft, a first detection assembly used for detecting the operating force of thetransmission block in the axial direction and a second detection assembly used for detecting the operating moment of the transmission block in the circumferential direction, and the first detection assembly is located in the axial direction of the transmission block; the second detection assembly is located in the circumferential direction of the transmission block. The manual control operation device is used for accurately detecting the force / moment of an operator in a vascular intervention training operation, timely realizing movement and force tactile feedback, and providing a real trainingenvironment for the operator so as to improve the operation skill of the operator.

Description

technical field [0001] The present invention relates to the technical field of medical training equipment, in particular to a manual operation device based on a vascular interventional surgery training system. Background technique [0002] Vascular interventional surgery is a very effective treatment that has gradually emerged in the past ten years. It has the advantages of less trauma, less bleeding, and accurate intervention sites. At the same time, the incidence of complications of vascular interventional surgery was negatively correlated with the number of angiography cases, indicating that the more skilled the operation, the lower the possibility of complications. [0003] However, compared with the increasing incidence of cardiovascular and cerebrovascular diseases year by year, the number of doctors who can really skillfully perform vascular interventional surgery is far behind, so it is necessary to train more excellent and skilled doctors for vascular interventional...

Problems solved by technology

[0004] Traditional vascular interventional training methods include: cadavers, human phantom models, animals, etc. Training operations are performed through training equipment. During the training process, it is often difficult to grasp the movement trajectory of the catheter, such as how to correctly advance, retreat or rotate. When obstacles are encountered during training, how to realize force feedback so as to train more accurately

[0005] Existing patent CN201210185159 - a device for real-time measurement of catheter intervention force and torque in cardiovascular interventional surgery. This patent wears the doctor's thumb and index finger in the device respectively, and performs detection and feedback through the device of force and torque. The device Although it is possible to have direct contact with the doctor's finger operation, because the vascular intervention requires precision and the doctor's work time is long, the doctor is prone to fatigue in such a posture for a long time, which will cause a large surgical error, so this device is not conducive to the doctor operation; in addition, the pressure sensors in the above-mentioned patents are 3 groups, which are equally spaced on the inner wall of the outer cylindrical shell, and there will be certain errors when detecting force and moment
