Catheter pushing device and method for vascular interventional procedures

Abstract

The invention provides a catheter pushing device and method for vascular interventional surgery. The device comprises a base, a catheter, a cradle-type rotating bracket with a balance weight, a firstfixing bracket, a second fixing bracket, a first hollow shaft, a second hollow shaft, a first motor, a coupling, a blood splash prevention cover, a linear drive member and a detachable roller member,the blood splash prevention cover is mounted on the upper surface of the detachable roller member through a cover groove of the upper surface of the detachable roller member; the linear drive member is fixedly connected to the cradle-type rotating bracket by a bottom plate on the linear drive member, and the linear drive member is separated from the blood splash prevention cover and rotates with the rotation of the cradle-type rotating bracket, so that closed space is formed between the blood splash prevention cover and an isolation structure; it is avoided that blood is splashed into other parts of a pushing device during the movement of the catheter, parts which need to be disinfected and replaced for each operation are reduced, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vascular interventional surgery devices, in particular to a catheter pushing device and method for vascular interventional surgery. Background technique [0002] Although vascular interventional surgery has greatly cured vascular diseases and reduced the suffering of patients, it also resulted in doctors needing a longer actual exposure to X-rays, especially for the needs of guiding wires and catheters. X-ray machines often need to be turned on frequently, which brings damage to the doctor's health, and because of the need to wear heavy lead clothing, it also leads to frequent occupational diseases of the doctor's lumbar spine. For this reason, both at home and abroad are devoting themselves to developing auxiliary devices for vascular interventional surgery, so as to liberate doctors from X-ray radiation and reduce the work intensity of doctors. [0003] In vascular interventional procedures, the guide ...

Problems solved by technology

[0004] According to the search and analysis of the published domestic and foreign patents, the main problem is that the catheter is not closed and the equipment is polluted

Although the patent of Corindus Inc. of the United States directly drives the catheter through the mechanical arm, which avoids the problem of polluting equipment, it increases the complexity of the problem
