[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 2 and Figure 3 As shown, the present invention provides a great saphenous vein stripping device head, which makes it easier to control the rhythm of pulling mainly by changing the direction of force.

[0023] The head of the great saphenous vein stripping device comprises a fixed box 1, inside which a rotating shaft 2 is rotatably connected via a bearing, the rotating shaft 2 passes through both sides of the fixed box 1, and one end of the rotating shaft 2 is fixedly connected to a winding drum 3 for winding a guide wire, and the other end is fixedly connected to a handle 4, a fixed frame 5 is fixedly connected to the outer surface of the winding drum 3, a first opening 6 is provided on the side of the fixed frame 5 away from the winding drum 3, a support plate 7 fixedly connected to the fixed box 1 is provided above the winding drum 3, and a guide 8 for guiding the guide wire to pass through is detachably connected to the bottom of the support plate 7;

[0024] The length of the first opening 6 is greater than the diameter of the guide wire, and the length of the fixing frame 5 is less than the length of the handle.

[0025] As shown in the attached figure Figure 1 As shown, currently when stripping the great saphenous vein, the user holds the handle with the hand and pulls the guide wire out by pulling the handle. The whole process is very laborious and it is not easy to control the rhythm of pulling, which makes the pulling process intermittent and even causes the stripped blood vessel to be broken. When the guide wire is too long, the handle is only at one end of the guide wire. As the guide wire is pulled out, subsequent force will become more difficult. Therefore, it is necessary to develop a great saphenous vein stripping device head with easy-to-control pulling rhythm.

[0026] This embodiment uses the device to drag the guide wire and change the direction of the force, which can easily control the rhythm of pulling, so that the guide wire is pulled out at a uniform speed, preventing the occurrence of detached blood vessels being pulled out, and no matter how long the guide wire is, or whether it is in the early or late stages of dragging the guide wire, it will not affect the force used to drag the guide wire and the speed of withdrawal.

[0027] In actual use, 1. place the device on one side of the handle, and make the extension direction of the guide wire perpendicular to the horizontal setting direction of the winding drum 3;

[0028] 2. Hold the handle and pass the guide wire through the guide member 8;

[0029] 3. Place the handle on the side of the fixing frame 5 away from the guide wire, and place the guide wire connected to the handle in the first opening 6;

[0030] 4. Turning the handle 4 will drive the winding drum 3 to rotate. Since the fixed frame 5 limits the handle, the guide wire is pulled as the winding drum 3 rotates, so that the guide wire is wound on the winding drum 3. Only by turning the handle 4, the rhythm of pulling the guide wire can be controlled, and the operation is easier.

[0031] As a preferred embodiment of this embodiment, the specific structure of the guide member 8 is further defined as follows: Figure 2 and Figure 4 As shown, the guide member 8 is configured to be in a spherical shell shape, and a receiving cavity 9 is formed inside the guide member 8. An inlet 10 is provided at one end of the guide member 8, an outlet 11 is provided at the other end, and a second opening 12 is provided on the outer surface of the guide member 8, and the second opening 12 is connected to both the inlet 10 and the outlet 11.

[0032] The guide member 8 is made of elastic material so that the guide member 8 can be deformed under stress.

[0033] When passing the guide wire through the guide member 8, the specific operation is to allow the guide wire to enter the inside of the guide member 8 from the second opening 12, and then place the guide wire at the inlet 10 and the outlet 11. When the guide wire passes through the guide member 8, the waste liquid on the outer surface of the guide wire is removed and retained in the accommodating cavity 9, so that the winding drum 3 is easier to clean.

[0034] Furthermore, the diameter of the inlet 10 is greater than the diameter of the outlet 11 , the outlet 11 is arranged on the side of the guide 8 close to the fixed frame 5 , and the height of the second opening 12 is higher than the height of the center of the guide 8 .

[0035] When pulling the guide wire, the guide wire first passes through the inlet 10 and then through the outlet 11. Since the diameter of the inlet 10 is large, the waste liquid on the outer surface of the guide wire will not be retained. When the guide wire passes through the outlet 11, the waste liquid on the outer surface of the guide wire is retained and retained inside the accommodating chamber 9. The height of the second opening 12 is higher than the height of the center of the guide member 8, and the retained waste liquid will not fall from the second opening 12.

[0036] The guide member 8 is detachably connected to the support plate 7 by means of snap connection or screw fixing, so that the guide member 8 is easily replaced and cleaned.

[0037] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
