Description

Technical Field

[0001] The present invention belongs to the technical field of interventional treatment equipment, and in particular relates to a peripheral vascular interventional treatment device and a method of using the same. Background Art

[0002] Peripheral vascular interventional therapy is a technique that uses percutaneous puncture under the guidance of medical imaging equipment to diagnose or treat blood vessels other than intracranial blood vessels and coronary blood vessels. This treatment method is a branch of interventional therapy, between surgical and medical treatment. The interventional therapy guidewire is an important device in interventional surgery, mainly used to guide and operate the treatment device into a specific part of the body.

[0003] When the doctor introduces the guide wire into the patient's blood vessel, he needs to rub the guide wire with his hands to make it turn, and push the guide wire with his hands to make it move forward in the blood vessel. This control method requires the doctor to directly touch the guide wire with his hands. The guide wire is relatively small. When using the hand to rotate it to make it turn, often a small rubbing of the hand will cause the guide wire to make a large turn, which is difficult to operate. In addition, the doctor's gloved hands are prone to slipping when they come into contact with the smooth surface of the guide wire, which is not conducive to controlling the guide wire.

[0004] To this end, those skilled in the art have proposed a peripheral vascular interventional treatment device and a method of using the same to solve the problems raised by the background art.

[0036] The bearing mechanism includes a base 3 and a first positioning plate 1 and a second positioning plate 2 fixedly mounted at both ends of the upper surface of the base 3. The first positioning plate 1 and the second positioning plate 2 are both circular plate structures. The first positioning plate 1 and the second positioning plate 2 are respectively provided with a first slot 4 and a second slot 5 on one surface. The first positioning plate 1 is provided with a scale line 8 on one surface.

[0037] The control mechanism includes an extrusion assembly arranged on the side of the second positioning disk 2. There are two extrusion assemblies. One end of each of the two extrusion assemblies is connected with a clamping plate 17. The clamping plate 17 is an arc-shaped plate structure. The clamping plate 17 is located in the first slot 4. A catheter 13 is arranged between the two clamping plates 17. A guide wire 14 is arranged in the catheter 13. A steering groove 6 is arranged on the side of the first positioning disk 1. A steering slider 7 is arranged in the steering groove 6. The steering slider 7 is slidably matched with the steering groove 6. One end of the steering slider 7 is connected to a connecting bin 9. One end of the connecting bin 9 is fixedly connected with a sleeve bin 10. The sleeve bin 10 and the connecting bin 9 are both located in the first slot 4. A positioning assembly is arranged inside the sleeve bin 10. The positioning assembly is extruded and matched with the side of the guide wire 14.

[0038] Specifically, the extrusion assembly includes a threaded barrel 15 arranged on the side surface of the second positioning plate 2, and a push screw 16 and a connecting rod are arranged inside the threaded barrel 15. The push screw 16 is threadedly matched with the threaded barrel 15, one end of the connecting rod is connected to the clamping plate 17, and the connecting rod is slidably matched with the inside of the threaded barrel 15.

[0039] Specifically, the positioning assembly includes a positioning hole 12 formed in the sleeve compartment 10 , and a first clamping seat 28 and a second clamping seat 29 are fixedly disposed on the inner peripheral side surface of the positioning hole 12 .

[0040] Specifically, the first clamping seat 28 and the second clamping seat 29 are respectively provided with a first groove 30 and a second groove 31 . The first groove 30 and the second groove 31 are both semicircular groove structures. The first groove 30 and the second groove 31 are both clamped and matched with the guide wire 14 .

[0041] Specifically, a mounting frame 20 is provided on the upper surface of the steering slider 7 , and a first movable shaft 34 and a second movable shaft 26 are respectively inserted into the mounting frame 20 and the connection chamber 9 , and movable rollers 24 are provided on the first movable shaft 34 and the second movable shaft 26 .

At the same time, the toggle block 21 on the mounting frame 20 is manually moved to drive the rubber push roller 27 to rotate through the transmission effect of the belt 25, and then the rubber push roller 27 conveys the guide wire 14 outward through the friction between it and the guide wire 14:

[0049] Specifically, there is damping between the steering slider 7 and the steering slot 6 .

[0050] As can be seen from the above, the present invention can install the device on a fixed platform by providing an extension plate 18 with a mounting groove 19, thereby providing a stable carrier for the use of the device, thereby providing stability when the guide wire 14 is introduced, and by providing a clamping plate 17 and a sleeve bin 10 with a first groove 30 and a second groove 31, limiting measures can be provided for the catheter 13 and the guide wire 14 respectively, and the entry direction of the guide wire 14 can be adjusted by sliding the steering slider 7, and at the same time, the rotation of the rubber push roller 27 can drive the guide wire 14 to extend forward into the patient's blood vessel.
