Pull assistance device for varicosity stripping

Abstract

Provided is a pull assistance device for varicosity stripping. A cavity is formed in the front upper portion of a handle (1) to serve as a machine cabin (102), the upper end of the machine cabin (102)is provided with an opening, the upper end of a puller (2) extends out of the opening, the lower portion of the puller (2) is connected with a wire compression block (3) through a transmission mechanism, a wire clamping groove (4) is longitudinally formed in the lower portion of the front end of the handle (1), a pressure bearing block (6) is fixed to the lower edge of the wire clamping groove (4), the bottom surface of the wire compression block (3) is at the upper portion of the wire clamping groove (4), the bottom surface of the wire compression block (3) is provided with compression teeth(303), and the top surface of the pressure bearing block (6) is provided with bearing teeth (601). By arranging the transmission mechanism, the pull assistance device can be easily operated in use, astable and enough guide wire clamping action force can be obtained, an assembly structure design is exquisite and reasonable, the operation is flexible, stripping and penetration are implemented easily, tissue damage is less, the pain of a patient is relieved, the bleeding time is shortened, wounded surfaces are decreased, installation and replacement are quick and convenient, the accurate efficiency of stripping diseased great saphenous veins and cirsoid branch veins is improved, and the surgical risk is reduced.

Description

technical field

[0001] The invention relates to the structure improvement technology of IPC classification A61B17 / 00 surgical instrument or A61B17 / 32 surgical cutting instrument, especially a varicose vein stripping and pulling aid. Background technique

[0002] Varicose veins refer to tortuous and dilated veins due to factors such as blood stasis and weak venous walls. Varicose veins can occur in multiple parts of the body. For example, hemorrhoids are actually a type of varicose veins. Clinically visible varicose veins include esophageal and gastric fundus, varicocele, and abdominal wall varicose veins. The most common site of varicose veins is the lower extremities. It is worth emphasizing that varicose veins are secondary manifestations of other lesions. There are many causes of varicose veins of the lower extremities, the most common being simple superficial varicose veins of the lower extremities, the main cause of which is the insufficiency of the femoral saphenous ...

Embodiment 1

[0038] Embodiment 1: as attached figure 1 , 2 As shown in and 3, there is a cavity in the front upper part of the handle 1 as the machine compartment 102, the upper end of the machine compartment 102 is open, the upper end of the puller 2 protrudes from the opening, the lower part of the puller 2 is connected with the wire pressing block 3 through a transmission mechanism, and the handle 1 The lower part of the front end is longitudinally provided with a wire clamping groove 4, and a pressure bearing block 6 is fixed along the lower wire clamping groove 4. The bottom surface of the wire pressing block 3 is on the upper part of the wire clamping groove 4, and the wire pressing block 3 has pressing teeth 303 on the bottom surface of the wire clamping block. 6 top surfaces have bearing teeth 601.

[0039] In the foregoing, the pin shaft 101 is fixedly installed horizontally on the upper part of the machine compartment 102, the lower end of the puller 2 is connected to the cam 7,...

Embodiment 2

[0046] Embodiment 2: as attached Figure 7 As shown, the pin shaft 101 is fixedly installed horizontally on the upper part of the machine compartment 102, the cam 7 is installed on the pin shaft 101, and the lower part of the cam 7 is connected to the wire pressing block 3 by transmission; the motor 8 and the battery 9 are installed inside the handle 1, and the motor 8 is connected to the cam 7 shaft , The puller 2 is connected to the motor 8 and the battery 9 through a circuit. A bite force sensor 10 is installed on the top surface of the pressure block 6 or the bottom surface of the wire pressing block 3 . Wherein, the battery 9 is a rechargeable battery, or the battery 9 is replaced by an external power supply.

Embodiment 3

[0047] Embodiment 3: as attached Figure 8 As shown, the lower part of the machine compartment 102 is horizontally fixed with a sliding nail 107, and the corresponding position on the pressing block 3 is vertically provided with a lifting groove 305, and the fixing sliding nail 107 is inserted into the lifting groove 305 to slide. The wire pressing block 3 moves up and down along the lifting groove 305 driven by the cam 7 .
