Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically to a positioning aid for surgical resection of tumors on the body surface. Background Technology
[0002] Superficial tumors refer to tumors originating from superficial sites such as the skin, skin appendages, and subcutaneous tissue. These tumors can be benign or malignant, and their manifestations and effects on the body vary. The presence of superficial tumors often affects appearance. For example, hemangiomas may cause noticeable purplish-red lumps on the skin, or skin cancer lesions may cause ulceration, scab formation, and other changes, all of which negatively impact a patient's appearance. For individuals concerned about their appearance or those who are particularly self-conscious, plastic surgery to remove superficial tumors is crucial.
[0003] Currently, during surgery for superficial tumors, benign tumors are typically removed at a certain distance from the tumor margin. This distance usually depends on the type and size of the tumor. To assist plastic surgeons in determining the resection extent, a tumor resection localization aid device is often used for positioning before resection. For example, there is a tumor surface localization device with publication number CN219230155U.
[0004] Positioning aids for surgical resection of superficial tumors typically use rings placed around the outside of the tumor for positioning. However, because the shapes of tumors vary from patient to patient, fixed-size and fixed-shape positioning rings are difficult to fit different tumor shapes. This means that during surgery, doctors often need to frequently change positioning rings of different sizes to meet positioning requirements. When changing positioning rings of different sizes, doctors also need to cut out corresponding surgical incisions on sterile drapes or replace the sterile drapes directly, which not only affects the efficiency of the surgery but also increases the cost. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a positioning auxiliary device for surgical resection of superficial tumors. The positioning frame is adjustable in size, eliminating the need for frequent replacements and thus improving surgical efficiency. Furthermore, multiple positioning plates are used in conjunction to locate the superficial tumor, preventing tumor displacement from affecting the removal efficiency. In addition, the positioning frame can both fix the sterile drape and avoid the waste caused by cutting the sterile drape, thereby reducing the cost of surgical procedures.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning auxiliary device for surgical resection of superficial tumors, comprising a positioning frame, wherein at least one positioning plate is provided inside the positioning frame for assisting in the positioning of superficial tumors, the positioning frame comprising multiple telescopic frame plates, each telescopic frame plate comprising two slidably connected sliding plates, and both sliding plates having grooves machined at their top ends, and both sliding grooves having the same adjusting component for adjusting the position of the positioning plate, adjacent sets of telescopic frame plates being detachably connected by two sliding plates, each sliding plate having a rectangular groove on the side away from the positioning plate, and a pressure plate being provided inside the rectangular groove, the pressure plate and the rectangular groove fixing sterile surgical drape.
[0007] Preferably, the number of telescopic frame plates is set to four sets, and the four sets of telescopic frame plates form a frame-shaped positioning frame. The length of each set of telescopic frame plates can be adjusted, so the size of the positioning frame can be adjusted.
[0008] Preferably, the adjustment assembly includes an adjustment block located at the top of two sliding plates. The adjustment block has a cavity inside, and a connecting rod is slidably arranged inside the cavity. One end of the connecting rod passes through the adjustment block and is fixed to the positioning plate. The connecting rod can support the positioning plate to locate tumors on the body surface.
[0009] Preferably, a compression spring is connected between the connecting rod and the cavity, and a pull rod is fixedly provided at the end of the connecting rod away from the positioning plate. The pull rod at the end away from the connecting rod passes through the compression spring and the adjusting block in sequence and extends out of the outside of the adjusting block.
[0010] When the positioning plate comes into contact with the tumor on the body surface, the tumor compresses the spring, generating a reverse force. This reverse force then pushes the positioning plate to remain in contact with the tumor.
[0011] Preferably, each adjusting block has at least one fastening bolt through its top. The fastening bolt is threaded to the adjusting block. Tightening the fastening bolt so that its bottom end contacts the inner wall of the groove can fix the adjusting block and prevent it from shaking.
[0012] Preferably, each rectangular groove has at least one storage slot on its bottom inner wall, and each pressure plate has a compression spring two fixedly connected to its bottom end in the same number as the storage slot. The bottom end of the compression spring two is connected to the bottom inner wall of the storage slot. The storage slot can both store the compression spring two and limit the compression spring two to prevent it from shifting during extension and retraction.
[0013] Preferably, each pressure plate extends outward from a rectangular groove at one end, allowing the plastic surgeon to quickly adjust the height of the pressure plate.
[0014] Preferably, each skateboard and each adjustment block is made of polyethylene material, and each positioning plate is made of medical-grade silicone. Medical-grade silicone is soft and will not put too much pressure on the patient's skin.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. This utility model uses multiple telescopic frame plates to form a positioning frame. The size of the positioning frame is adjustable, which has a wider range of applications and does not require frequent replacement, thereby improving surgical efficiency. At the same time, the positioning plate is stably in contact with the tumor on the patient's body surface under the support of the adjustment component. Multiple positioning plates are used to locate the tumor on the body surface, avoiding the displacement of the tumor and affecting the removal efficiency.
[0017] 2. By using a pressure plate in conjunction with multiple compression springs, the sterile surgical drape can be directly fixed to the positioning frame. This not only secures the sterile drape but also avoids the waste caused by cutting the drape, thus reducing the cost of surgical procedures. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Refer to the instruction manual appendix Figure 1-5This utility model provides a positioning auxiliary device for surgical resection of tumors on the body surface, including a positioning frame 1. The positioning frame 1 is provided with at least one positioning plate 2 inside, which is used to assist in positioning tumors on the body surface. Each positioning plate 2 is made of medical silicone. The positioning frame 1 includes multiple telescopic frame plates 101. The number of telescopic frame plates 101 is set to four groups, and the four groups of telescopic frame plates 101 form a frame-shaped positioning frame 1.
[0028] Each telescopic frame plate 101 includes two slidingly connected slide plates 1011, and the top of each slide plate 1011 is machined with a groove 1012. The same adjustment component 3 for adjusting the position of the positioning plate 2 is provided in the two grooves 1012. The two adjacent sets of telescopic frame plates 101 are detachably connected by the two slide plates 1011.
[0029] Furthermore, the adjustment component 3 includes an adjustment block 301 located at the top of the two sliding plates 1011. The adjustment block 301 has a cavity 302 inside, and a connecting rod 303 is slidably arranged inside the cavity 302. One end of the connecting rod 303 passes through the adjustment block 301 and is fixed to the positioning plate 2. The connecting rod 303 can support the positioning plate 2 to locate tumors on the body surface.
[0030] A compression spring 304 is connected between the connecting rod 303 and the cavity 302. A pull rod 305 is fixedly provided at the end of the connecting rod 303 away from the positioning plate 2. The end of the pull rod 305 away from the connecting rod 303 passes through the compression spring 304 and the adjusting block 301 in sequence and extends out of the outside of the adjusting block 301. When the positioning plate 2 comes into contact with the tumor on the body surface, the tumor on the body surface squeezes the compression spring 304 to generate a reverse force. The reverse force of the compression spring 304 then pushes the positioning plate 2 to always come into contact with the tumor on the body surface.
[0031] To facilitate the adjustment of the position of the adjusting block 301, at least one fastening bolt 6 is passed through the top of each adjusting block 301, and the fastening bolt 6 is threadedly connected to the adjusting block 301.
[0032] Each slide 1011 and each adjustment block 301 is made of polyethylene material. Polyethylene material has a low density, so the slide 1011 and adjustment block 301 are lightweight and will not put too much pressure on the patient's skin. At the same time, polyethylene material has good recyclability, which makes it easy to recycle and reuse the positioning frame 1, thereby reducing the cost of surgery.
[0033] During the actual surgery, the plastic surgeon first visually assesses the size of the tumor on the patient's body surface. Then, the surgeon grasps two symmetrical telescopic frame plates 101 on the left and right sides to adjust their width, and then grasps two symmetrical telescopic frame plates 101 on the front and back to adjust their length, thereby expanding the entire positioning frame 1. After the positioning frame 1 is placed on the tumor, the positioning frame 1 is then reduced by multiple telescopic frame plates 101, so that multiple positioning plates 2 are in contact with the tumor. This eliminates the need for frequent changes of positioning devices of different sizes, thus improving surgical efficiency. Since the positioning plates 2 are made of medical-grade silicone, their soft material does not cause excessive pressure. At the same time, when the positioning plates 2 are squeezed by the tumor, they compress the spring 304 through the connecting rod 303. The compression spring 304 contracts and generates a counterforce, thus pushing the positioning plates 2 in the opposite direction to squeeze the tumor. Multiple positioning plates 2 work together to position the tumor, preventing the tumor from shifting and affecting the removal efficiency.
[0034] Refer to the instruction manual appendix Figure 2 and Figure 4 Each slide plate 1011 has a rectangular groove 4 on the side away from the positioning plate 2. The rectangular groove 4 has a pressure plate 5 inside. The pressure plate 5 and the rectangular groove 4 fix the sterile surgical cloth. Each rectangular groove 4 has at least one storage slot 7 processed on the bottom inner wall. Each pressure plate 5 has a compression spring 8 with the same number as the storage slot 7 fixedly connected to the bottom end. The bottom end of the compression spring 8 is connected to the bottom inner wall of the storage slot 7.
[0035] Furthermore, to facilitate the installation and removal of sterile drapes by plastic surgeons, a rectangular groove 4 extends outward from one end of each pressure plate 5 to facilitate adjustment of the height of the pressure plate 5.
[0036] After adjusting the size of the positioning frame 1, the plastic surgeon first presses down on the pressure plate 5 inside the rectangular groove 4. At this time, the multiple compression springs 8 at the bottom of the pressure plate 5 are squeezed. Then, when the doctor inserts one side of the sterile drape covering the patient's skin between the rectangular groove 4 and the pressure plate 5, as... Figure 2 As shown, after releasing the pressure plate 5, the multiple compression springs 8 are no longer under pressure, so they push the pressure plate 5 upward to fix the sterile cloth. By fixing the sterile cloth on the positioning frame 1, the sterile cloth can be fixed and the waste caused by cutting the sterile cloth can be avoided, making it more convenient to use.
[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
