Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1-3 as shown,

[0024] A slave hand of a vascular interventional surgery robot for controlling a catheter-guide wire, which includes two hollow ultrasonic motors 22, 23, two linear ultrasonic motors 24, 25, and two ordinary motors 18, and the linear ultrasonic motor drives the hollow ultrasonic motor along the guide rail Move to drive the guide wire or catheter to move linearly, and two ordinary motors are used to drive two locking mechanisms 27, 29 to clamp the guide wire 12 and catheter 21; the two locking mechanisms are respectively connected to the rotors of the corresponding hollow ultrasonic motors In solid connection, the guide wire and catheter are respectively positioned in their respective locking mechanisms and are coaxial with the rotation center of the hollow ultrasonic motor, pass through the hollow ultrasonic motor...

Abstract

A robot hand slave for vascular interventional surgery that manipulates a catheter-guide wire, which is characterized in that it includes two hollow ultrasonic motors, two linear ultrasonic motors, and two ordinary motors, and the linear ultrasonic motor drives the hollow ultrasonic motor to move along the guide rail to drive the guide rail. The wire or catheter moves linearly, and two ordinary motors are used to drive two locking mechanisms to clamp the guide wire and catheter respectively; the two locking mechanisms are respectively fixedly connected with the rotors of the corresponding hollow ultrasonic motors, and the guide wire and catheter are positioned separately In the respective locking mechanisms, they are coaxial with the rotation center of the hollow ultrasonic motor, pass through the hollow ultrasonic motor, and rotate with the rotation of the hollow ultrasonic motor. The invention has the advantages of simple structure, good operability and convenient use, and is beneficial to improving operation efficiency.

Description

technical field [0001] The present invention relates to a medical device, in particular to an interventional treatment catheter guide wire delivery technology, in particular to a vascular interventional robot slave hand for manipulating a catheter-guide wire based on hollow motor and linear motor technology. Background technique [0002] At present, minimally invasive vascular interventional surgery has become an important means of treating cardiovascular diseases and tumors recognized by the medical community due to its characteristics of small trauma, high safety, light patient pain, fast postoperative recovery, and few complications. Combining robotic technology with minimally invasive vascular interventional surgery, and assisting interventional doctors in delivering interventional devices such as guide wires and catheters by designing a dedicated surgical robot system is one of the important ways to improve the effect of interventional therapy. [0003] Before the vascu...
