Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a hook buckle for preventing skin burns in breast surgery. Background Art

[0002] Retractors are often called incision dilators or incision spreaders. These instruments are used to temporarily open the incision during surgery so that the surgeon can more easily perform the operation, observe the internal tissues or organs, and complete the required treatment;

[0003] During breast surgery, surgeons need to make incisions to access breast tissue for examination, tumor removal, or other treatments. Incision expanders can help spread the incision and stabilize the surrounding tissue, allowing surgeons to operate more easily while minimizing damage to surrounding normal tissue.

[0004] In summary, the existing devices still have the following technical problems: most of the retractors currently used hook one end on the inner side of the skin, and then expand the incision by pulling the other end. At that time, this method requires long-term manual support, which wastes physical strength and reduces the surgical operation space. At the same time, the skin retractors for breast surgery are made of metal materials. Therefore, during the operation, when the electric knife cuts tissue or burns tissue blood vessels, it will come into contact with the skin retractor, thereby scalding the skin tissue through the thermal conductivity of the skin retractor. For this reason, it is necessary to propose a breast surgery anti-retractor skin burn buckle to provide a new technical solution to solve the technical problems mentioned in the above patents.

[0028] As described in the background technology, most of the retractors currently used hook one end on the inner side of the skin, and then expand the incision by pulling the other end. At that time, this method requires long-term manual support, which wastes physical strength and reduces the surgical operation space. At the same time, the skin retractors used in breast surgery are made of metal materials. Therefore, during the operation, when the electric knife cuts tissue or burns tissue blood vessels, it will come into contact with the skin retractor, thereby scalding the skin tissue through the thermal conductivity of the skin retractor.

[0029] In order to solve this technical problem, the utility model provides a breast surgery anti-retractor skin burn buckle, which is used for breast surgery incision expansion.

[0030] Specifically, please refer to Figure 1-Figure 5 The breast surgery anti-retractor skin burn buckle specifically includes an expansion mechanism 1 and a transmission locking mechanism 2. The expansion mechanism 1 is used to expand the surgical opening, and the top of the expansion mechanism 1 is provided with a transmission locking mechanism 2 for locking the expansion mechanism 1;

[0031] The expansion mechanism 1 comprises a first crossbar 3, a second crossbar 4, an extension assembly and a hook assembly. The second crossbar 4 is mirror-disposed on one side of the first crossbar 3.

[0032] The breast surgery anti-retractor skin burn buckle provided by the utility model is provided with an expansion mechanism 1. After the breast incision is completed, the buckle 11 is extended to the underlying skin, and the first cross bar 3 and the second cross bar 4 are pulled to both sides at the same time to expand the incision, thereby achieving the purpose of wound expansion.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 2-Figure 5 A breast surgery anti-retractor skin burn buckle, comprising an expansion mechanism 1 and a transmission locking mechanism 2, wherein the expansion mechanism 1 is used to expand the surgical opening, and the top of the expansion mechanism 1 is provided with a transmission locking mechanism 2 for locking the expansion mechanism 1;

[0036] The expansion mechanism 1 comprises a first crossbar 3, a second crossbar 4, an extension assembly and a hook assembly. The second crossbar 4 is mirror-disposed on one side of the first crossbar 3.

[0037] Specifically, the extension assembly includes a first shaft rod 5, a first connecting rod 6, a second shaft rod 7, a third shaft rod 8 and a second connecting rod 9. The first cross bar 3 is fixedly connected to the first shaft rod 5 at both ends, and the surfaces of the two first shaft rods 5 are respectively rotatably connected to the first connecting rods 6. The end of the first connecting rod 6 away from the first shaft rod 5 is rotatably connected to the second shaft rod 7. The second cross bar 4 is fixedly connected to the third shaft rod 8 at both ends, and the surfaces of the two third shaft rods 8 are respectively rotatably connected to the second connecting rods 9. The end of the second connecting rod 9 away from the third shaft rod 8 is rotatably connected to the surface of the second shaft rod 7.

[0038] Specifically, the hook assembly includes a bracket 10 and a buckle 11. The bottom surfaces of the first cross bar 3 and the second cross bar 4 are respectively fixedly connected to two brackets 10. One end of the four brackets 10 away from the first cross bar 3 and the second cross bar 4 is buckled and connected to the buckle 11.

[0039] Specifically, the transmission locking mechanism 2 includes a first guide frame 12, a bidirectional threaded rod 13, a first limit block 14, and a screw block 15 guide assembly. The top surfaces of the first cross bar 3 and the second cross bar 4 are fixedly connected to the first guide frame 12 in a mirror-image manner. The middle parts of the two first guide frames 12 are connected to the bidirectional threaded rod 13. The bidirectional threaded rod 13 is threadedly connected to the two first guide frames 12. The two ends of the bidirectional threaded rod 13 are fixedly connected to the first limit blocks 14, and the middle part of the bidirectional threaded rod 13 is fixedly connected to the screw block 15.

[0040] With the above structural design, when the device is used, an incision is first made at the diseased part of the patient, and then the tripod 10 is inserted into the inside of the incision. When the buckle 11 on the surface of the tripod 10 contacts the inner wall of the incision, the first cross bar 3 and the second cross bar 4 are pulled to both sides at the same time. During the process of pulling the first cross bar 3 and the second cross bar 4 to both sides, the incision can be opened through the buckle 11 at the bottom, thereby quickly completing the expansion of the incision.

[0041] Embodiment 2:

[0042] The anti-scalding hook buckle for breast surgery provided in Example 1 is further optimized. Specifically, Figure 2-Figure 4 As shown, the guide assembly includes a second guide frame 16, a sliding rod 17 and a second limit block 18. The top surfaces of the first cross bar 3 and the second cross bar 4 are fixedly connected to two second guide frames 16 in a mirror-image manner. The middle parts of the two second guide frames 16 are slidably connected with the sliding rod 17, and the two ends of the sliding rod 17 are fixedly connected with the second limit blocks 18.

[0043] Specifically, the extension components in the expansion mechanism 1 are two groups, and the two groups of extension mechanisms are respectively connected to the two ends of the first cross bar 3 and the second cross bar 4.

[0044] Through the above structural design, the incision is expanded by setting a transmission locking mechanism 2 to cooperate with the expansion mechanism 1. When the tripod 10 is inserted into the inside of the incision and the buckle 11 contacts the inner surface of the incision, the bidirectional threaded rod 13 is driven to rotate by rotating the screw block 15. The rotation of the bidirectional threaded rod 13 can push the first cross bar 3 and the second cross bar 4 on both sides to move to both sides at the same time through the first guide frame 12. At the same time, the second guide frame 16 on the surface of the first cross bar 3 and the second cross bar 4 slides on the surface of the slide bar 17. When the first cross bar 3 and the second cross bar 4 move away from each other, the second connecting rod 9 and the first connecting rod 6 in the middle respectively rotate with the first shaft rod 5, the second shaft rod 7 and the third shaft rod 8 as the axis, thereby completing the expansion of the incision and facilitating the auxiliary role in the later surgery.
