Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical technology, and specifically relates to a skin suture hook. Background Technology
[0002] In clinical practice, it is common for skin wounds to be unable to be directly sutured due to excessive wound tension. Skin traction is used to treat such wounds that are difficult to suture directly. Skin traction utilizes the extensibility of the skin, applying continuous mechanical tension to the soft tissue of the skin to increase the skin area and cover the wound, which is then finally sutured closed.
[0003] Existing skin traction fixation devices connect a tension controller to a traction line that pulls on the soft tissue of the skin. Several skin anchors are installed on the traction line to fix the soft tissue of the skin. The skin anchors are installed on the soft tissue of the skin on both sides of the wound, with an even number of anchors symmetrically arranged. The tension controller applies force to the traction line, thereby causing the skin anchors on both sides of the wound to move towards each other, achieving stable traction of the soft tissue of the wound required for skin traction surgery, making the skin traction surgery safe. However, existing skin anchors are prone to falling off during skin traction, cannot be stably anchored on the soft tissue of the skin on both sides of the wound, and are prone to exerting oblique traction force on the skin, causing skin damage.
[0004] Therefore, in order to address the above-mentioned technical problems, designing skin suture retractors that can be more stably embedded in the wound skin without causing excessive damage to the skin is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a skin suture retractor that allows the retractor to be more stably embedded in the wound skin without causing excessive damage to the skin.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] A skin suture retractor includes a hook portion connected to a traction suture, a connector disposed on the hook portion, and a first hook and a second hook disposed on the connector. The first hook and the second hook are arranged in parallel. The connector is a U-shaped pull rod. The first hook and the second hook are respectively connected to the support arm of the U-shaped pull rod. The hook portion is connected to the closed end of the U-shaped pull rod. The hook portion includes a connecting rod connected to the closed end of the U-shaped pull rod, a bend portion connected to the connecting rod and bending in the opposite direction to the first hook and the second hook, and a stop rod connected to the bend portion.
[0008] Preferably, both the first hook and the second hook are integrally formed with the U-shaped tie rod.
[0009] Preferably, the stop bar extends toward the connecting rod and forms a traction line passage between it and the connecting rod.
[0010] Preferably, the connecting rod is provided with a baffle for closing the traction line passage, and the baffle abuts against the stop rod at the end away from the connecting rod.
[0011] Preferably, the baffle is connected to the connecting rod via a torsion spring hinge.
[0012] Preferably, the traction wire has an opening size of 1mm to 10mm.
[0013] Preferably, the angle between the first hook and the second hook and the U-shaped tie rod is 5° to 45°.
[0014] Preferably, the end of the first hook away from the connector is provided with a first conical tip, and the end of the second hook away from the connector is provided with a second conical tip.
[0015] The present invention achieves the following technical advantages over the prior art:
[0016] By setting the first and second hooks, the hooks can effectively penetrate the soft tissue around the wound, allowing the retractor to be more stably embedded in the wound skin. Furthermore, by setting the first and second hooks parallel to each other, when the traction line is tightened by the controller, the force exerted on the first and second hooks after they penetrate the skin is perpendicular to the skin, without any oblique component force, effectively preventing excessive skin damage. The U-shaped pull rod, with its two parallel arms, ensures that the first and second hooks are not subjected to forces from other directions, further preventing excessive skin damage. Finally, the stop bar prevents the traction line from detaching from the hook section, allowing the hook section to connect to the traction line more stably. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] The purpose of this invention is to provide a skin suture retractor that allows the retractor to be more stably embedded in the wound skin without causing excessive damage to the skin.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] refer to Figures 1-2The skin suture retractor disclosed in this embodiment of the present invention includes at least a hook portion connected to a traction suture. The hook portion is provided with a connector, and the connector is provided with a first hook 1 and a second hook 7 embedded in the soft tissue surrounding the wound. The first hook 1 and the second hook 7 are arranged in parallel. By setting the first hook 1 and the second hook 7, the retractor can effectively pierce the soft tissue surrounding the wound, allowing it to be more stably embedded in the wound skin. Furthermore, by arranging the first hook 1 and the second hook 7 in parallel, when the traction suture is tightened by the controller, the force exerted on the first hook 1 and the second hook 7 after piercing the skin is a force perpendicular to the skin, without any oblique component force, effectively avoiding excessive skin damage. The connector is a U-shaped pull rod 2. The first hook 1 and the second hook 7 are respectively connected to the support arm of the U-shaped pull rod 2. The hook part is connected to the closed end of the U-shaped pull rod 2. By setting the U-shaped pull rod 2, since the two support arms of the U-shaped pull rod 2 are also parallel to each other, it can be ensured that the first hook 1 and the second hook 7 will not be subjected to the component force in other directions, further avoiding excessive damage to the skin. The hook part includes a connecting rod 3 connected to the closed end of the U-shaped pull rod 2. A bending part 5 is provided on the connecting rod 3. The bending direction of the bending part 5 is opposite to the bending direction of the first hook 1 and the second hook 7. A stop bar 4 for preventing the traction line from coming off is connected to the bending part 5. By setting the stop bar 4, the traction line can be prevented from coming off from the hook part, so that the hook part can be more stably connected to the traction line.
[0027] It should be noted that the hook section is located in the middle of the closed end of the U-shaped tie rod 2.
[0028] refer to Figures 1-3 As one implementation method, the first hook 1 and the second hook 7 are both integrally formed with the U-shaped tie rod 2, which can ensure a simple structure.
[0029] refer to Figures 1-4 In one embodiment, the stop lever 4 extends toward the connecting rod 3, and a traction line passage is formed between the stop lever 4 and the connecting rod 3, extending the stop lever 4 toward the connecting rod 3 (i.e., as per the instruction manual). Figure 4 The included angle B is greater than 0°, which can prevent the traction line from coming off, and the passage opening can ensure that the traction line can pass through smoothly during installation.
[0030] refer to Figures 1-4 As one implementation method, a baffle is provided on the connecting rod 3 to close the passage of the traction line. The end of the baffle away from the connecting rod 3 abuts against the baffle. By setting the baffle, the baffle can be opened during installation to allow the traction line to pass through. When traction is required, the passage of the traction line can be closed by the baffle to further prevent the traction line from coming out.
[0031] refer to Figures 1-4In one implementation, the baffle is connected to the connecting rod 3 via a torsion spring hinge. By setting the torsion spring hinge, the opening and closing of the baffle can be guaranteed, thereby realizing the closure and opening of the traction line passage.
[0032] refer to Figures 1-4 As one implementation method, the size of the traction line passage is 1mm to 10mm. The traction line passage can be set as small as possible, as long as the traction line can pass through.
[0033] refer to Figures 1-4 As one implementation method, the angle between the first hook 1 and the second hook 7 and the U-shaped pull rod 2 (i.e., as per the instruction manual) Figure 4 The value of A is 5° to 45°, which allows the first hook 1 and the second hook 7 to be more stably embedded in the wound skin.
[0034] refer to Figures 1-4 In one embodiment, the first hook 1 and the second hook 7 are provided with a first cone tip 6 at the end away from the connector, and the second hook 7 is provided with a second cone tip 8 at the end away from the connector, which makes it convenient for the first hook 1 and the second hook 7 to pierce the wound skin.
[0035] In practical application, when the tension controller applies force to the traction line, thereby causing several skin suture hooks on both sides of the wound to move towards each other, the angle between the first hook 1 and the second hook 7 and the U-shaped pull rod 2 is 5° to 45°, which can stably fix the first hook 1 and the second hook 7 to the soft tissue of the skin. As the skin tension increases, the first hook 1 and the second hook 7 can be further embedded in the skin, realizing the stable wound soft component traction required for skin traction surgery, making skin traction surgery safe and avoiding excessive skin damage. The hook part can prevent the traction line from falling off during traction.
[0036] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0037] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the utility model.
