Problems solved by technology

[0003] The purpose of the present invention is to provide a catheter interventional device with delivery resistance feedback function to solve the problem that the existing catheter interventional device is not compact enough, has no delivery resistance feedback function, and interventional surgeons must operate on the surgical site
[0005] The present invention has the following beneficial effects: 1. Since the present invention adopts a differential mechanism and has a relatively large length-to-diameter ratio, it solves the problem that the current interventional device is not compact in structure and easily interferes with other surgical equipment

Abstract

The invention relates to a catheter intervention device with the conveying resistance feedback function, belonging to a catheter intervention device, and aiming at solving the problems that the existing catheter intervention device is not compact in structure, does not have the conveying resistance feedback function and is operated at the surgical site by doctors getting involved the surgery. Output shafts of a left and a right motors are fixedly sheathed with a left side driving gear and a first-stage driving gear; the left side driving gear is meshed with a left side driven gear; the first-stage driving gear is meshed with a first-stage driven gear; a second-stage driving bevel gear is fixedly connected with the first-stage driven gear; the second-stage driving bevel gear is meshed with a second-stage driven bevel gear; a third-stage driving gear is fixedly connected with the second-stage driven bevel gear; the third-stage driving gear is meshed with a third-stage driven gear; a driving friction inner wheel is fixedly provided with a touch force sensor; the driving friction inner wheel is connected with a driving friction outer wheel by the touch force sensor; a signal output end of the touch force sensor is connected with a signal input end of an amplification circuit board; and an amplifying signal output end of the amplification circuit board is connected with a signal input end of an inner ring of a second electric conduction sliding ring. The catheter intervention device is used for continuously conveying a catheter and feedback of the force.

Description

technical field [0001] The invention relates to a catheter intervention device, in particular to a catheter intervention device with a delivery resistance feedback function used in intravascular minimally invasive interventional operations. Background technique [0002] In the traditional minimally invasive vascular interventional surgery, the intubation operation is performed manually by the doctor at the surgical site. There are many disadvantages in this operation method: (1) The environment of the surgical site is poor. The doctor not only suffers from radiation damage, but also has to bear heavy pressure Lead clothing; (2), the operation is not stable enough, and the accuracy is not easy to guarantee. Therefore, it is necessary to develop a dedicated catheter intervention device to replace the doctor to complete various operations at the operation site, so that the doctor can perform master-slave operations in the operating room separated from the operating room. Since...
