Separated ablation catheter and sheathing canal combined driving device

Abstract

The invention provides a separated ablation catheter and sheathing canal combined driving device. The device comprises a driving platform, a driving structure panel and adaptive consumables, and the driving platform comprises a catheter axial propelling and retreating driving module, a catheter head bending driving module and a sheathing canal axial propelling and retreating driving module; the driving structure panel is provided with a plurality of mounting holes, the adaptive consumables are fixed on the driving platform through the mounting holes, the adaptive consumables comprise a catheter and a motion control consumable thereof as well as a sheath and a motion control consumable thereof, and the catheter axial propulsion and retraction driving module is used for controlling axial propulsion and retraction operations of the catheter; the catheter head bending driving module is used for controlling the catheter head bending operation; and the sheath tube axial propulsion and retraction driving module is used for controlling sheath tube axial propelling and retreating operation, reducing the complexity of combined operation of the catheter and the sheath tube, meeting the requirement that an ablation target point reaches satisfactory catheter attachment or stable attachment is long enough, and improving the success rate and efficiency of an operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined drive device for a separate ablation catheter and a sheath tube. Background technique [0002] In radiofrequency ablation surgery, when it is difficult to accurately locate the ablation target with the catheter, it is often necessary to operate the sheath at the same time or separately, and through the rotation or advance and retreat of the sheath, the catheter can be assisted to reach the difficult target. At present, the linked operation of the catheter and the sheath can only be realized through manual manipulation by the operator, and the assistance of a surgical assistant is required when necessary. [0003] The basic methods of operating the ablation catheter in vitro to locate the endocardial target include: advancing and withdrawing the catheter, bending the tip of the catheter at a desired angle in one direction, and rotating the catheter in a positive...

AI Technical Summary

Problems solved by technology

[0005] The combined operation of the above-mentioned catheter and sheath requires the operator to keep the sheath and catheter stable for a long time during the operation, because the operation technique is complicated and the operation risk is high, so that many ablation targets cannot achieve satisfactory catheter abutment or cannot be stabilized Adhesion long enough to result in ineffective and inefficient procedures
