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

[0055] see Figure 1-4 , a guidewire / catheter delivery device for a vascular interventional robot, if in this embodiment it is mainly used to deliver guidewires, it includes:

[0056] The driving part 1 includes a first driving unit 101 and a second driving unit 102;

[0057] At least one set of advancing and retreating wire modules 21, the first driving unit 101 is used to drive the advancing and retreating wire modules 21, so as to realize the movement of the guide wire 6 along its axial direction;

[0058] The wire rotation module 22 further includes a clamping assembly 221, the clamping assembly 221 is used to clamp the guide wire 6, the second driving unit 102 is connected to the clamping assembly 221, and is used to drive the clamping assembly 221 to rotate along the axis of the guide wire 6 , and then drive the guide wire 6 to rotate;

[0059] In this embodiment, two groups of advancing and retreating wire modules 21 are included. Along the axis direction of the guide...

Embodiment approach

[0070] In a preferred embodiment, the first pressing wheel adjustment assembly includes a first sliding member 2214 and a first locking member. The first sliding member 2214 is slidably arranged on the clamping seat 2211. The first sliding member 2214 and the first pressing wheel The axle of 2213 is fixedly connected;

[0071] Push the first sliding member 2214, and the first sliding member 2214 slides along the straight line where the axis of the first pressing wheel 2213 and the axis of the fixed wheel 2212 are located, so as to adjust the axial distance between the first pressing wheel 2213 and the fixing wheel 2212 ;

[0072] The first locking part is connected with the first sliding part 2214, and is used for locking the state where the first sliding part 2214 slides to the target position.

[0073] There are many implementations of the first pressure wheel adjustment assembly, such as screw nuts, slide rail sliders, etc., using motor control to lock the slider or nut to...

Embodiment 2

[0098] The present invention also provides a vascular interventional surgery robot, including the guide wire delivery device of the vascular interventional surgery robot in the above embodiment.

Abstract

The invention discloses a guide wire / catheter conveying device of a vascular interventional surgical robot and the vascular interventional surgical robot. The conveying device comprises a driving part, one or more groups of wire feeding and retreating modules and a wire rotating module, wherein the driving part comprises first driving units and a second driving unit; the first driving units are used for driving the wire feeding and retreating modules so that a guide wire / catheter can move in the axial direction of the first driving units; and the wire rotating module further comprises a clamping assembly, the clamping assembly is used for clamping the guide wire / catheter, and the second driving unit is connected with the clamping assembly and used for driving the clamping assembly to rotate along the axis of the guide wire / catheter so as to drive the guide wire / catheter to rotate. By adopting an automatic mode, guide wire / catheter rotation and wire feeding and retreating are performed synergistically or independently, the two hands of a doctor are liberated, the working time of the doctor in a radiation environment is shortened, the failure rate of an operation is reduced, and the accuracy and precision of pushing and rotation are guaranteed, so that the safety of the operation is greatly improved, and the working efficiency of doctors is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a guidewire / catheter delivery device for a vascular interventional surgery robot 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 wir...
