Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0054] It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in the following examples are only relative concepts or refer to the normal use status of the product, and should not be ...

Abstract

The invention is applicable to the field of medical devices and discloses a catheter push control method and a catheter push device for a vascular interventional surgical robot. The catheter push control method includes a force measuring step and a regulating step. The regulating step is a step of setting a controller for regulating motion parameters during the catheter pushing process to prevent the blood vessel from being punctured during the catheter pushing process. The force measuring step comprises: providing a pressure sensor on a friction block assembly for clamping and rotating a catheter to twisting the catheter for detecting the pressure of the friction block assembly against the catheter; and providing a torque sensor for a catheter to pass through on a support base to detect the torque of the catheter. Through indirect measurement method, the method can measure the resistance applied to the head of the catheter and the torque of the catheter at the same time to effectively control the movement of the catheter. As the method allows doctors to operate and control remotely, the method reduces harm of surgeries to medical staff and patients.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a catheter pushing control method and catheter pushing equipment of a vascular interventional surgery robot. Background technique [0002] In recent years, the incidence of cardiovascular disease has been increasing year by year, and it has been recognized as one of the important killers threatening human health. In my country, with the rapid increase of population aging, cardiovascular disease poses an increasingly serious threat to the health of the elderly, and people pay more and more attention to this type of disease. The treatment of cardiovascular diseases includes drug therapy and interventional therapy. Among them, interventional therapy is a method of directly exposing and treating lesions without using a large-scale incision. Specifically, the operation method of interventional therapy is: incision in the skin with a diameter of A few millimeters, can only...
