Problems solved by technology

In vascular interventional surgery, due to the small size of the operation object, the doctor's operation skills are high, and long-term training is required, and the interventional operation generally takes a long time, which may cause the doctor to experience hand tremors due to fatigue, thereby increasing the operating time. potential risk of
At the same time, due to the existence of medical imaging equipment, doctors need to be exposed to radiation for a long time, which will cause great harm to the body

Embodiment 1

[0060] see Figure 1-9 , a guidewire / catheter delivery device for vascular intervention, in this embodiment, a guidewire is taken as an example, including:

[0061] The clamping assembly 21 is used to clamp the guide wire 4. The clamping assembly 21 includes a clamping seat 2101, at least one driving wheel 2102 and at least one driven wheel 2103. The driving wheel 2102 and the driven wheel 2103 are rotatably mounted on the clamping seat 2101, and symmetrically arranged on both sides of the guide wire 4, considering the stability of the guide wire 4, there are two driving wheels 2102 and two driven wheels 2103 in this embodiment, of course, multiple driving wheels 2102 and multiple a driven wheel 2103, which is not limited here;

[0062] The driving part 1 includes an advancing and retreating wire driving unit 101 and a rotating wire driving unit 102,

[0063] The advancing and retreating wire driving unit 101 is connected with the driving wheel 2102 and drives the driving wh...

Embodiment approach

[0074] The preferred embodiment also includes a spinning wire transmission unit 23, the spinning wire driving unit 102 is connected to the clamping seat 2101 through the spinning wire transmission unit 23, and the spinning wire driving unit 23 is used to change the direction of the rotation center line of the spinning wire driving unit 102, and the The rotation centerline of the spinning drive unit 102 is changed from the vertical direction to the horizontal direction, and there are also many ways to realize it. As stated above, in this embodiment, bevel gear transmission is also used to change the direction.

[0075] That is, the spinning transmission unit 23 includes a fifth bevel gear 2301 and a sixth bevel gear 2302 meshing with each other, the fifth bevel gear 2301 is arranged horizontally, the sixth bevel gear 2302 is vertically arranged, and the fifth bevel gear 2301 is connected with the spinning drive unit 102 , the sixth bevel gear 2302 is connected with the clamping ...

Abstract

The invention discloses a guide wire / catheter delivery device for vascular intervention and a using method of the guide wire / catheter delivery device and a vascular intervention surgical robot. The delivery device comprises a clamping assembly used for clamping a guide wire / catheter, and a driving part, wherein the clamping assembly comprises a clamping base, one or more driving wheels and one or more driven wheels, the driving wheels and the driven wheels are rotationally mounted on the clamping base, and are symmetrically arranged on the two sides of the guide wire / catheter; the driving part comprises a wire feeding and retreating driving unit and a wire rotating driving unit, the wire feeding and retreating driving unit is connected with the driving wheels and drives the driving wheels to rotate, and the driving wheels rotate to drive the guide wire / catheter to move in the axial direction; and the wire rotating driving unit is connected with the clamping base and drives the clamping base to rotate in the axial direction of the guide wire / catheter, and then the guide wire / catheter is driven to rotate. The guide wire / catheter rotates around a shaft and axially moves independently or rotates around the shaft and axially moves synchronously in an automatic mode, guide wire propelling accuracy and precision are improved, and therefore the operation safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a guide wire / catheter delivery device for vascular intervention and a vascular interventional surgery robot. Background technique [0002] Vascular interventional surgery is a method in which doctors, under the guidance of subtractive angiography (DSA) equipment, manipulate interventional instruments to move in human blood vessels, and finally accurately reach the lesion and perform treatment. Common interventional devices include venous catheters, guide wires, filters, and spring emboli. Vascular interventional surgery has become an important means of treating cardiovascular diseases. Compared with traditional surgery, it has the characteristics of small incision, fast recovery and good effect. [0003] At present, the traditional operation method of vascular interventional surgery is that the doctor manually sends the catheter and guide wire into the patien...
