Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical stripping aids, and in particular to a stripping aid for varicose vein surgery. Background Technology
[0002] Varicose veins refer to the tortuous and dilated veins caused by factors such as blood stasis and weak vein walls. Varicose veins can occur in many parts of the body; for example, hemorrhoids are a type of varicose vein. Clinically, other examples include esophageal and gastric varices, varicocele, and abdominal wall varices. The most common site for varicose veins is the lower extremities. Common surgical treatments typically use specialized stripping instruments with a stainless steel wire as a guidewire. Two semi-circular cylindrical stripping heads are fixed in the middle of the guidewire. The instrument is inserted proximal or distal to the incised great saphenous vein and exited through an incision at the other end. By slowly pulling and tightening the vein bound to the semi-circular cylindrical stripping heads in different directions, the diseased vein is stripped inward or outward. During varicose vein stripping surgery, the surgeon often encounters the challenge of having to exert considerable force to tear the diseased varicose veins from under the skin and within the muscle.
[0003] Existing traction devices generally require the surgeon to grip the device tightly and pull it to one side, meaning the surgeon must maintain a constant grip strength for a long time, which can lead to muscle tension or overwork in the surgeon's hand, affecting subsequent surgical procedures. Therefore, we propose a stripping aid for varicose vein surgery to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a stripping aid for varicose vein surgery to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A varicose vein stripping aid for surgery includes: a shell, two top blocks fixedly connected to the top of the shell, two hollow frames fixedly connected to the bottom of the shell, pressure plates slidably connected inside the two hollow frames, a handle slidably connected inside the shell, an extension plate fixedly connected to the top of the handle, two rectangular plates fixedly connected to the top of the extension plate, round bodies fixedly connected to the top of the two rectangular plates, positive cones fixedly connected to the top of the two round bodies, inverted cones slidably connected to the outside of the two positive cones, and two limiting triangular plates slidably connected inside the two top blocks. The outside of the positive cones and inverted cones on the same side movably abut against the tops of the corresponding limiting triangular plates on the same side.
[0006] Preferably, a hollow plate is fixedly connected inside each of the two top blocks, a trapezoidal plate is fixedly connected to the side of each of the two limiting triangular plates on the same side that are far apart from each other, a second spring is fixedly connected to the side of each of the two trapezoidal plates on the same side that are far apart from each other, one end of each of the two second springs on the same side that are far apart from each other is fixedly connected to the inner wall of the two hollow plates on the same side, and the two trapezoidal plates on the same side are slidably connected inside the two corresponding hollow plates on the same side.
[0007] Preferably, each of the two pressure plates has a vertical plate fixedly connected to its top, and each of the two vertical plates has a connecting rod rotatably connected inside. The two connecting rods are rotatably connected to the inside of the same extension plate on their respective sides. The outer shell has two longitudinal columns fixedly connected inside, and the two connecting rods are rotatably connected to the outside of the corresponding longitudinal columns.
[0008] Preferably, both sides of the outer shell are provided with built-in grooves, and a second guide post is fixedly connected to the inside of each of the two built-in grooves. A side plate is fixedly connected to the side of each of the two vertical plates that are close to each other, and the two side plates are slidably connected to the outside of the corresponding second guide post.
[0009] Preferably, a first guide post is fixedly connected to the inner top of the outer shell, two side blocks are fixedly connected to the outer side of the first guide post, and two side grooves are provided inside the extension plate, with both side blocks slidably connected inside the corresponding side grooves.
[0010] Preferably, two columns are fixedly connected inside the outer shell, and two circular grooves are provided inside the extension plate, with both columns slidably connected inside the corresponding circular grooves.
[0011] Preferably, a third spring is fixedly connected to the outside of both columns, and the bottom ends of both third springs are fixedly connected to the top of the same extension plate.
[0012] In this utility model, a stripping aid for varicose vein surgery is described. By passing the guide wire through the inside of two hollow frames, the surgeon further grasps the outer shell and places his fingers under the handle, further contracting and exerting force to make the handle move upward. Then, the upward movement of the handle drives the two connecting rods on the side that are close to each other to rotate clockwise and counterclockwise respectively, which causes the two vertical plates on both sides to move downward, and then drives the two pressure plates on both sides to move downward to clamp and fix the guide wire. In this invention, a stripping aid for varicose vein surgery is described. After the surgeon clamps and fixes the varicose vein, continuing to grip the handle causes the extension plate to move upwards. At this point, the rectangular plates on both sides move upwards, causing the two conical bodies to abut against the tops of the two limiting triangular plates on the same side. Further upward movement causes the bottoms of the conical bodies on the same side to abut against the bottoms of the two limiting triangular plates on the same side. Therefore, even when the surgeon releases their grip, the guidewire remains stably clamped, effectively relieving muscle tension. When the guidewire is no longer needed, only... To continue gripping firmly, the same-side positive cone continues to move upward. At that time, the bottom of the two limiting triangular plates on the same side abuts against the outside of the same-side inverted cone. Since the same-side inverted cone slides outside the corresponding round body, when the two limiting triangular plates on the same side abut against the outside of the corresponding inverted cone, the surgeon releases the grip. At that time, the same-side inverted cone will abut against the bottom of the corresponding positive cone, which will cause the two limiting triangular plates on the same side to finally slide against the top of the same-side positive cone. This will cause the rectangular plate to move downward, and finally drive the pressure plates on both sides to move upward to release the clamping of the guidewire. This utility model has a reasonable structural design. The combination of connecting rod, extension plate, vertical plate and pressure plate realizes the function of clamping and fixing guide wire, which improves surgical efficiency. The combination of limiting triangular plate, second spring, positive cone, circle and inverted cone realizes the function of relaxing the surgeon's hand muscles, which improves the working efficiency of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figure 1-4 A stripping aid for varicose vein surgery includes: a shell 1, two top blocks 2 fixedly connected to the top of the shell 1, two hollow frames 3 fixedly connected to the bottom of the shell 1, pressure plates 10 slidably connected inside the two hollow frames 3, a handle 4 slidably connected inside the shell 1, an extension plate 5 fixedly connected to the top of the handle 4, two rectangular plates 12 fixedly connected to the top of the extension plate 5, a round body 13 fixedly connected to the top of each of the two rectangular plates 12, a positive cone 14 fixedly connected to the top of each of the two round bodies 13, an inverted cone 15 slidably connected to the outside of each of the two positive cones 14, and two limiting triangular plates 19 slidably connected inside the two top blocks 2. The outside of the positive cone 14 and the inverted cone 15 on the same side are movably abutting against the top of the two limiting triangular plates 19 on the same side.
[0017] In this embodiment, a hollow plate 16 is fixedly connected inside each of the two top blocks 2. A trapezoidal plate 18 is fixedly connected to the side of each of the two limiting triangular plates 19 on the same side that are far apart from each other. A second spring 17 is fixedly connected to the side of each of the two trapezoidal plates 18 on the same side that are far apart from each other. The ends of the two second springs 17 on the same side that are far apart from each other are fixedly connected to the inner wall of the two hollow plates 16 on the same side. The two trapezoidal plates 18 on the same side are slidably connected inside the two corresponding hollow plates 16 on the same side, thereby realizing the reset function of the limiting triangular plates 19.
[0018] In this embodiment, vertical plates 11 are fixedly connected to the top of both pressure plates 10, and connecting rods 24 are rotatably connected inside both vertical plates 11. The sides of the two connecting rods 24 that are close to each other are rotatably connected to the inside of the two sides of the same extension plate 5. Two longitudinal columns 23 are fixedly connected inside the outer shell 1, and two connecting rods 24 are rotatably connected to the outside of the corresponding longitudinal columns 23, thereby realizing the clamping function of the guide wire.
[0019] In this embodiment, both sides of the outer shell 1 are provided with built-in grooves 20. The interior of each of the two built-in grooves 20 is fixedly connected with a second guide post 22. The two vertical plates 11 are fixedly connected with side plates 21 on the side that is close to each other. The two side plates 21 are slidably connected to the outside of the corresponding second guide post 22. The outside of each of the two pillars 7 is fixedly connected with a third spring 25. The bottom ends of the two third springs 25 are fixedly connected to the top of the same extension plate 5, thereby realizing the reset function of the extension plate 5.
[0020] In this embodiment, a first guide post 6 is fixedly connected to the top of the inner shell 1, and two side blocks 9 are fixedly connected to the outside of the first guide post 6. Two side grooves 8 are provided inside the extension plate 5, and the two side blocks 9 are slidably connected inside the corresponding side grooves 8. Two columns 7 are fixedly connected inside the inner shell 1, and two circular grooves are provided inside the extension plate 5. The two columns 7 are slidably connected inside the corresponding circular grooves, thereby realizing the guiding function of the side blocks 9.
[0021] In this embodiment, during surgery, the guidewire is passed through the interior of the two hollow frames 3. The surgeon then grips the outer shell 1 and places their fingers under the handle 4, further contracting the grip to move it upwards. This upward movement of the handle 4 causes the two connecting rods 24 on the adjacent sides to rotate clockwise and counterclockwise respectively, causing the two vertical plates 11 to move downwards. This, in turn, causes the two pressure plates 10 to move downwards, clamping and fixing the guidewire. After the surgeon has clamped and fixed the guidewire, they continue to grip the handle 4, causing the extension plate 5 to continue moving upwards. At this time, the two rectangular plates 12 move upwards, causing the two positive cones 14 to abut against the tops of the two limiting triangular plates 19 on the same side. Continuing upwards, the bottoms of the positive cones 14 abut against the bottoms of the two limiting triangular plates 19 on the same side. Thus, even when the surgeon releases the handle 4, the guidewire is still stably clamped, effectively relieving the surgeon's muscle tension. Furthermore, when it is no longer necessary to clamp the guidewire... At that time, as long as the handshake 4 is continued to be gripped tightly, the conical body 14 on the same side will continue to move upward. At that time, the bottom of the two limiting triangular plates 19 on the same side will abut against the outside of the inverted cone 15 on the same side. Since the inverted cone 15 on the same side slides on the outside of the corresponding circular body 13, when the two limiting triangular plates 19 on the same side abut against the outside of the corresponding inverted cone 15, and the surgeon releases the handshake 4, the inverted cone 15 on the same side will abut against the bottom of the corresponding conical body 14, thereby making the two limiting triangular plates 19 on the same side... Finally, the sliding contact with the top of the same-side positive cone 14 causes the rectangular plate 12 to move downward, ultimately driving the pressure plates 10 on both sides to move upward and release the clamping of the guidewire. The clamping and fixing function of the guidewire is achieved through the cooperation of the connecting rod 24, the extension plate 5, the vertical plate 11 and the pressure plate 10, which improves the efficiency of the operation. The relaxation function of the surgeon's hand muscles is achieved through the cooperation of the limiting triangular plate 19, the second spring 17, the positive cone 14, the circular body 13 and the inverted cone 15, which improves the working efficiency of the device.
