Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a great saphenous vein stripper. Background Art

[0002] Varicose vein of lower extremity (VVLE) is a common chronic venous vascular disease in clinical practice. When the disease occurs, patients often show symptoms such as widening, protrusion, and bending of the subcutaneous superficial veins. In severe cases, subcutaneous skin ulceration, bleeding, infection, etc. may occur, which seriously affects the limb function. If timely and effective treatment measures are not taken, the daily life and work of patients will be seriously affected. The main cause of varicose veins in the lower extremities is the poor structure and function of the great saphenous vein valve. Surgery is the main means of clinical treatment of VVLE, among which high ligation and stripping of the great saphenous vein is one of the commonly used procedures. In addition, foam sclerotherapy (mainly lauromacrogol or polidocanol) and endovascular laser closure are also routinely used. The former has the advantages of less trauma and low cost, and the disadvantages are that it can only close superficial varicose veins, cannot cure the great saphenous vein problem, and is very easy to relapse; the latter has the advantages of less trauma than traditional stripping, and the disadvantages are high cost, and the clinical effect is extremely dependent on the level and experience of the operator. Therefore, high ligation and stripping of the great saphenous vein is still the main treatment method. During the operation, the stripper is usually inserted along the direction of the great saphenous vein (from the distal end to the proximal end), and the main trunk of the great saphenous vein is stripped in reverse segments.

[0003] For example, patent CN215349151U discloses a permeable vein stripping device. The use of the stripper in this patent has been improved compared with the most traditional great saphenous vein stripping technique, but it still has the following disadvantages: the length of the stripper is limited and cannot penetrate the entire great saphenous vein trunk. The reason why it cannot be extended is that the stripper probe is relatively thick and cannot smoothly reach the proximal end when the trunk is severely varicose vein. In addition, the stripper connecting section is too soft and not rigid enough to move forward easily. During the stripping process, due to the limited thickness of the probe, it is easy to make the venous bed difficult to loosen, resulting in incomplete stripping of the great saphenous vein and residual. Summary of the invention

[0004] The present application provides a great saphenous vein stripper to solve the above-mentioned technical problems.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: a great saphenous vein stripper, comprising: a guide wire and a stripper, one end of the guide wire is connected to a fixed component, and the stripper is provided with a through hole passing through the middle, wherein one end of the guide wire is inserted twice from one side of the through hole.

[0006] Furthermore, the stripper is cylindrical, and the ends of the stripper are round heads, and through holes penetrate the round heads on both sides, wherein the diameter of the middle part of the stripper is greater than the diameter of the ends of the stripper.

[0007] Furthermore, the stripper is made of plastic and has annular patterns on its surface.

[0008] Furthermore, the fixing assembly includes a conical clamping portion for clamping the lead-in wire and a handle, the clamping portion includes three clamping seats arranged in a Y shape, and the holding seats are slidably arranged at the end of the handle; a thread is provided on the outer side of the clamping seat, and a conical nut is provided on the outer side of the clamping seat for controlling the opening and closing of the clamping seat.

[0009] Furthermore, the handle includes a rotating rod connected to the clamping portion and a grip connected to the rotating rod. A threaded hole is provided in the grip near one end of the rotating rod, and a screw sleeved in the threaded hole is fixedly connected to the center of the end of the rotating rod.

[0010] Furthermore, a buckle is provided on the outer side wall of the end of the rotating rod close to the gripping rod, and a clamping block corresponding to the buckle is provided on the outer side of the gripping rod.

[0011] Furthermore, three Y-shaped sliding grooves are provided at the end of the rotating rod connected to the clamping portion, and sliding blocks corresponding to the sliding grooves are fixedly connected to the bottom of the clamping seat.

[0012] Furthermore, the threading wire is a sterilized steel wire folded and twisted into two strands, wherein the head end of the sterilized steel wire in the threading wire is connected to the tapered clamping portion.

[0013] The beneficial effects of the present application are as follows: the present application folds ordinary sterilized steel wire into a guide wire, thereby enhancing the rigidity of the guide wire and preventing the guide wire from being too soft to be inserted into the vein. At the same time, the clamping seat of the fixed component can effectively clamp the guide wire and drive the guide wire to rotate through the rotating rod, so that the guide wire can pass through the vein smoothly. At the same time, when the guide wire reaches the high-position disconnection point at the proximal end of the outgoing wire, the fixed stripper is fixed. The stripper has a larger head than the traditional stripper. During the process of extracting the great saphenous vein, it can ensure that the trunk vein is not easy to slip off, and the trunk is completely extracted. Generally, there is no need for segmented extraction, which ensures minimal trauma, and the required consumables are extremely cheap. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] See also Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the great saphenous vein stripper 2 of the present application. The great saphenous vein stripper 2 comprises: a threading wire 1 and a stripper 2, one end of the threading wire 1 is connected to a fixing component 3, and the stripper 2 is provided with a through hole 21 running through the middle, wherein one end of the threading wire 1 is inserted twice from one side of the through hole 21. The threading wire 1 in the above design is inserted into the vein, and then the wire head is extended to the high-position disconnection at the proximal end, and the stripper 2 is fixed by two insertions, so that the threading wire 1 is recovered from the distal end, and the stripper 2 is driven to be withdrawn from the great saphenous vein, which can ensure that the main vein is not easy to slip off, and the main trunk is completely extracted, and generally no segmented extraction is required.

[0018] See also Figure 2 , Figure 2 yes Figure 1 The schematic diagram of the structure of an embodiment of the stripper 2 in FIG. The stripper 2 is cylindrical, and the ends of the stripper 2 are round heads. The through holes 21 penetrate the round heads on both sides, wherein the diameter of the middle part of the stripper 2 is larger than the diameter of the ends of the stripper 2. The larger diameter of the middle part of the stripper 2 in the above design prevents the stripper 2 from slipping off the middle part of the great saphenous vein when being withdrawn.

[0019] The stripper 2 is made of plastic and has annular patterns on its surface. The stripper 2 in the above design is made of cheap materials such as plastic, which reduces the cost of use. At the same time, the annular patterns can further increase the friction on the surface of the stripper 2 to prevent the great saphenous vein from slipping.

[0020] See also Figure 3-4 , Figure 3 yes Figure 1 A schematic structural diagram of an embodiment of a fixing assembly in FIG. Figure 4 yes Figure 3 A schematic diagram of the structure of an embodiment of the clamping part in the embodiment. The fixing component 3 includes a conical clamping part 31 for clamping the threading wire 1 and a handle 32. The clamping part 31 includes three clamping seats 311 arranged in a Y shape, and the clamping seats are slidably arranged at the end of the handle 32; the outer side of the clamping seat 311 is provided with a thread, and the outer side of the clamping seat 311 is provided with a conical nut 4 for controlling the opening and closing of the clamping seat 311. The Y-shaped clamping seat 311 in the above design can be controlled to open and close by rotating the conical nut 4, so that the end of the threading wire 1 can be clamped at a distance, ensuring stable clamping while facilitating the rotation of the threading wire 1.

[0021] See also Figure 5 , Figure 5 yes Figure 3 The structural schematic diagram of an embodiment of the handle in the figure. The handle 32 includes a rotating rod 321 connected to the clamping portion 31 and a gripping rod 322 connected to the rotating rod 321. A threaded hole 323 is provided in the gripping rod 322 near one end of the rotating rod 321, and a screw 324 sleeved in the threaded hole 323 is fixedly connected to the center of the end of the rotating rod 321. The gripping rod 322 in the above design is used for medical staff to hold, and the rotating rod 321 can drive the threading wire 1 to rotate, which is convenient for inserting the saphenous vein. At the same time, when the screw 324 rotates, it moves away from the gripping rod 322, thereby slowly pushing the threading wire 1 forward, thereby reducing the patient's pain in the puncturing vein. According to different usage requirements, the length of the screw 324 of the rotating rod 321 can be reasonably adjusted to facilitate threading.

[0022] A buckle 51 is provided on the outer side wall of the end of the rotating rod 321 close to the gripping rod 322, and a block 52 corresponding to the buckle 51 is provided on the outer side of the gripping rod 322. The buckle 51 in the above design can clamp the block, so as to ensure that when the screw rod 324 is completely screwed into the threaded hole 323, the rotating rod 321 and the gripping rod 322 are stably connected to prevent the rotating rod 321 from rotating; when the rotating rod 321 needs to be rotated, the buckle can be opened and the rotating rod 321 can be rotated, so that the rotating rod 321 is separated from the gripping rod 322.

[0023] See also Figure 6 , Figure 6 yes Figure 3 The structural diagram of an embodiment of the handle end in FIG. The end of the rotating rod 321 connected to the clamping part 31 is provided with three Y-shaped slide grooves 325, and a slider 312 corresponding to the slide grooves 325 is fixedly connected to the bottom of the clamping seat 311. The clamping seat 311 in the above design can slide back and forth along the slide grooves 325 through the slider 312. When the conical nut 4 is rotated outward, the conical nut 4 squeezes the clamping seat 311 to slide toward the center, thereby completing the clamping operation; when the conical nut 4 is rotated inward, the conical nut 4 loosens the clamping seat 311, thereby facilitating the removal of the threading wire 1.

[0024] See also Figure 7 , Figure 7 yes Figure 1 The structural diagram of an embodiment of the threading wire in the embodiment of FIG. The threading wire 1 is a sterilized steel wire folded and twisted into a double strand, wherein the head end of the sterilized steel wire in the threading wire 1 is connected to the tapered clamping portion 31. The head end of the sterilized steel wire in the above design is used to be clamped by the clamping portion 31, so that the round head end can be used for threading, because the round head end is blunt and it is not easy to puncture the blood vessel when passing through the starting section of the large vein. Since the round head end is smaller than the heads of the two ends of the conventional stripper, it is much easier to insert, and due to the problem of steel wire stiffness, when encountering difficulty in moving, gently rotating the direction can generally still pass smoothly.

[0025] In the specific operation process, the sterilized steel wire is folded and twisted into two strands to make the threading wire 1, and the head end of the sterilized steel wire is inserted into the clamping part 31, and the conical nut 4 is rotated outward at the same time, and the conical nut 4 squeezes the clamping seat 311 to slide toward the center, and the threading wire 1 is operated from a stable clamping. Then, the round head end of the threading wire 1 is inserted into the vein from the distal end, and the rotating rod 321 of the handle 32 is rotated to allow the threading wire 1 to slowly enter and rotate into the vein until it reaches the high-position disconnection at the proximal end, and the round head end of the threading wire 1 is extended, and then the round head end is inserted from one end of the stripper 2 twice and tightened to complete the fixation of the stripper 2. Subsequently, the tail of the threading wire 1 is pulled at the distal end by gripping the handle 32. When the stripper 2 reaches the proximal trunk, the vein and the stripper 2 are ligated and fixed, and the distal wire is pulled again to strip the great saphenous vein trunk to the starting section in a "stripping" manner. Because the head of the stripper 2 is larger than that of the traditional stripper, the main vein is not likely to slip during the extraction of the great saphenous vein, and the main trunk is completely extracted. Generally, there is no need for segmented extraction, which ensures minimal trauma and extremely low prices for the required consumables.
