Embodiment 1

[0059] like figure 1 , figure 2 , image 3 As shown, a catheter guide wire control device for interventional surgery in this embodiment includes a housing 1, a clamping mechanism 3, a sleeve driving assembly 4 and a brake assembly 5, the clamping mechanism 3, and the sleeve driving assembly 4 And brake assembly 5 are all arranged in the housing 1.

[0060] Among them, such as figure 1 As shown, the housing 1 is a U-shaped structure with front and rear side walls. figure 1 In order to clearly see the internal structure of the device, the front wall of the housing 1 has been removed; the top opening of the housing 1 can be detachably installed with the upper cover 2, specifically, an ear is installed on each of the two opposite sides of the upper cover 2. The plate 201, the ear plate 201 and the housing 1 are connected by screws. After the housing 1 is covered with the upper cover 2, a relatively closed space is formed to protect its internal components, which is beneficia...

Embodiment 2

[0069] Using the catheter guide wire control device for interventional surgery in the first embodiment, the catheter or guide wire can be clamped, pushed and pulled, and twisted. Here, the catheter is used as an example to illustrate, and the details are as follows.

[0070] ①Conduit clamping operation

[0071] Firstly, the conduit passes through the brake part 320, the clamp part 330 and the sleeve 310 of the clamping mechanism 3; then, the brake assembly 5 works to brake the brake part 320, specifically, the push-pull electromagnet 530 Get electricity, pull the brake block 520 close to the brake disc 322 of the brake member 320, and contact and press the brake disc 322, the brake member 320 brakes; then, the sleeve drive assembly 4 drives the sleeve 310 of the clamping mechanism 3 to rotate, Specifically, the motor 430 is energized to drive the small herringbone gear 420 to rotate, the small herringbone gear 420 and the large herringbone gear 410 are meshed for transmission,...

Embodiment 3

[0078] A catheter guide wire control device for interventional surgery in this embodiment, on the basis of Embodiment 1, a dynamometer 7 is set between the support plate 460 and the lower support plate 640 on which the brake assembly 5 is installed, for detecting The pushing force of the catheter guidewire. Using this device can not only realize the clamping, pushing and pulling, and twisting operations on the catheter or guide wire in Embodiment 2, but also detect the pushing resistance of the catheter or guide wire. Here, the guide wire is used as an example to illustrate, and the details are as follows.

[0079] The clamping operation of the guide wire is the same as that in Embodiment 2. After the guide wire is clamped, the brake assembly 5 releases the brake part 320 of the clamping mechanism 3, and the clamping mechanism 3 moves along with the guide wire together under the push action of external force. Axial movement, the guide rail slider assembly 6 follows the sliding...

Abstract

The invention discloses a catheter and guide wire control device for an interventional operation and a control method of the catheter and guide wire control device, belonging to the technical field of minimally invasive vascular interventional operations. The device comprises a clamping mechanism, a sleeve driving assembly and a brake braking assembly, wherein the clamping mechanism comprises a sleeve, a braking part and a clamping part, after the clamping part with a clamping end is mounted in the braking part, the braking part is in threaded connection with the sleeve, a notch is formed in one end, with the clamping end, of the clamping part, and the clamping end is in conical fit with the sleeve; the sleeve driving assembly is used for driving the sleeve to rotate; the brake braking assembly is used for clamping or loosening the braking part. With the method, a catheter or a guide wire can be clamped, pushed and twisted, and force measurement also can be realized; the efficient, accurate and nondestructive clamping and loosening for the guide wire and the catheter can be realized, and the catheter and the guide wire can be cooperatively operated.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive vascular interventional surgery, and relates to a control technology for a catheter guide wire in an interventional operation, and more specifically relates to a catheter guide wire control device for an interventional operation and a control method thereof. Background technique [0002] The increasing incidence of cardiovascular and cerebrovascular diseases has seriously affected national health and social life, and brought enormous pressure to China's medical and health system. Cardiovascular and cerebrovascular diseases have become one of the three major causes of human death. Every year, 16.7 million people die from cardiovascular and cerebrovascular diseases in the world, accounting for 29.2% of all disease mortality. Every year, there are 9 million patients with cardiovascular and cerebrovascular diseases in my country. 2.5 million people died. [0003] Cardiovascular and cerebrov...
