Sterile isolation method and system for rotational hand clamp in vascular intervention operation

Abstract

The invention provides a sterile isolation method and system for a rotational hand clamp in a vascular intervention operation. The method comprises the following steps: M1, connecting an overall isolation membrane sleeve, a left rotational harmonium sheath, a right rotational harmonium sheath, a moving hand clamp left sheath, a moving hand clamp right sheath, a moving hand clamp sealing membrane,a fixed hand clamp left sheath, a fixed hand clamp right sheath and a fixed hand clamp sealing membrane so as to form a sleeve bag of which the sealing degree is greater than a set threshold; M2, fixing the sleeve bag on a rotational hand clamp through a closing line; M3, sleeving the rotational hand clamp by the sleeve bag, respectively correspondingly sleeving a moving hand clamp left finger anda moving hand clamp right finer of the rotational hand clamp by the moving hand clamp left sheath and the moving hand clamp right sheath; M4, respectively correspondingly sleeving a fixed hand clampleft finger and a fixed hand clamp right finger of the rotational hand clamp by the fixed hand clamp left sheath and the fixed hand clamp right sheath; and M5, mounting the left rotational harmonium sheath and the right rotational harmonium sheath on a palm. The system is reasonable in structure and convenient to mount and dismount.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a method and system for aseptically isolating a spinner in vascular interventional surgery. Background technique [0002] Vascular interventional surgery robots generally adopt a master-slave teleoperation mode. The doctor operates the handle to transmit the operation command to the robot on the patient side through remote communication, and the robot operates the interventional equipment to complete the operation. The most important end effector in the operation is the clamp hand, which usually completes two actions, that is, clamping the catheter guide wire and then rotating it. Since the catheter guide wire is a device that directly enters the human body, it has very high requirements for sterility. [0003] At present, the device operation method of the master-slave teleoperation surgical robot for vascular intervention generally uses two rollers to press the catheter ...

AI Technical Summary

Problems solved by technology

This method of clamping with fingers is flexible, and the catheter guide wire is very convenient to install and disassemble, but the difficulty lies in how to strictly isolate the rotating mechanism, dynamic clamping mechanism, fixed clamping mechanism and interventional consumables to meet clinical needs
