A human-computer interaction device, system and method for a wire feeding mechanism in vascular interventional surgery

Abstract

The invention discloses a human-computer interaction system, device and method of a wire feeding mechanism for vascular interventional surgery based on surface electromyography. The system includes: an active guide wire, a first electrode piece, an arm, a second electrode piece, a myoelectric signal acquisition channel, a myoelectric signal acquisition instrument, a driven guide wire, a wire feeding mechanism and a control device; the first electrode piece It is used to be attached to the abductor pollicis brevis of the user; the second electrode sheet is used to be attached to the biceps of the user; the electromyographic signal acquisition instrument is used to collect electromyographic signals; The electric signal generates a control instruction; the wire feeding mechanism controls the radial stepping motor and the axial stepping motor to perform actions according to the received control instruction, and the radial stepping motor is used to rotate the driven guide wire, so The axial stepper motor is used to push the driven guide wire. The invention solves the problems of poor human-computer interaction transparency of the vascular interventional robot, low operation efficiency, changes in the natural operation habits of doctors, and the like.

Description

technical field [0001] The invention relates to the field of signal processing and pattern recognition, in particular to a human-computer interaction device, system and method of a wire feeding mechanism for vascular interventional surgery based on surface electromyography. Background technique [0002] At present, vascular interventional surgery robots have become an important tool to assist doctors in the treatment of cardiovascular and cerebrovascular diseases. Robot-assisted vascular interventional surgery means that the doctor, under the guidance of the digital subtraction angiography (DSA) system, manipulates the joystick or the operating handle to control the robot to push the guide wire (a soft wire with rigidity) to move in the human blood vessel. , to treat the lesion to achieve the purpose of embolization of malformed blood vessels, dissolution of thrombus, and expansion of narrow blood vessels. Through master-slave control, vascular interventional surgery robots...

Problems solved by technology

[0005] However, although these methods have carried out a lot of processing on the EMG signal and achieved good recognition results, they have not been applied to vascular interventional surgery, nor have they combined the surface EMG signal with the doctor's natural operation in vascular interventional surgery. linked, the existing technology does not take this into account
