[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0016] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, in the description of this specification, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0017] The ankle is the bone point where the lower end of the tibia and fibula of the lower leg is connected to the foot. Generally, in ordinary life, walking often sprains the foot, which can cause pain at the mildest and ligament sprain and even periosteum damage at the worst. The ankle bone generally does not fracture, and most of the time, the bone fracture occurs after the foot is twisted. Ankle fracture is a disease caused by partial or complete fracture of the bone due to trauma or pathology. The main manifestations are local swelling, pain, cyanosis, dysfunction, deformity and bone friction sound of the ankle. At this time, medial malleolus fracture repair surgery is needed for treatment. In the surgical treatment of medial malleolus fracture, in order to reduce the patient's pain and speed up the patient's postoperative healing speed, the current ankle reduction surgery adopts minimally invasive surgery, and it is very inconvenient to reduce the broken ankle bone at the tiny incision, and manual operation is very inconvenient, and the current holding forceps either cannot stably hold the ankle bone, or are not suitable for working in the tiny incision, making the surgical operation inconvenient.

[0018] The medial malleolus fracture reduction forceps according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0019] In the specific implementation mode 1 of the present application, Figure 1 and Figure 3 As shown, the present medial malleolus fracture reduction forceps, by setting a clamping hook base 3-1 of the ankle bone clamping hook 3 at the end of the clamp handle 2, is convenient for installing two clamping hooks 3-3 with adjustable hook spacing, so that the clamping hooks 3-3 can cooperate with the ankle bone clamping nail 4 capable of adjusting the pitch angle at the end of the clamp handle 1 to form a triangular clamping structure, so that the medial malleolus fracture reduction forceps (hereinafter referred to as "this patent") can clamp the ankle bone 5 more stably, and at the same time, with its compact characteristics, it can clamp the ankle bone 5 into the minimally invasive incision to adjust the position, so that the ankle bone 5 can better dock with the fracture, and complete the surgical purpose.

[0020] The utility model number of surgical ankle fracture reduction and fixation forceps is CN205268267U (hereinafter referred to as "this patent"). The Kirschner wire sleeve of this patent makes it impossible to clamp the ankle bone firmly in a tiny incision and move it accordingly. However, this patent uses an arc-shaped clamping hook 3-3 in combination with an ankle clamping nail 4 with adjustable pitch angle, which can clamp the ankle bone 5 more stably. At the same time, with the help of a relatively flat overall structure, it can adjust the posture of the ankle bone 5 in a relatively tiny incision and place it in the correct position.

[0021] The second embodiment is based on the first embodiment, and the other structures are the same, the only difference is that Figure 2 As shown, the ankle bone clamping hook 3 is made of stainless steel as a whole. There is an angle of 110 degrees between the handle and the hook of the clamping hook 3-3, and the handle is arc-shaped. In order to enable the clamping hook 3-3 to better adapt to different types of ankle bones 5 from multiple angles, the arc of the handle of the clamping hook 3-3 allows medical staff to adjust the angle of the clamping hook 3-3 by simply loosening the clamping hook fixing knob 3-2 and then pulling the handle of the clamping hook 3-3, which greatly expands the scope of application.

[0022] In order to further optimize the working efficiency of the present application, in order to increase the contact area between the ankle bone clamping nail 4 and the ankle bone 5, the ankle bone clamping nail 4 uses a metal plate to install two rows of four clamping bone nails. In order to further improve the clamping stability of the ankle bone clamping nail 4, the two rows of clamping bone nails on the metal plate of the ankle bone clamping nail 4 are inclined to each other.

[0023] When in use, the medial malleolus fracture reduction forceps are installed and sterilized, and the angles of the clamping hook 3-3 and the ankle bone clamping nail 4 are adjusted, and then the forceps can be put into use.

[0024] When the utility model is in use, the specific operations are as follows:

[0025] When in use, first disinfect this patent, after completion, rotate the clamping hook fixing knob 3-2 to loosen the clamping of the clamping hook 3-3, adjust the length of the arc-shaped handle of the clamping hook 3-3 at the lower end of the clamping hook base 3-1 according to the size of the ankle 5, to adjust the angle of the clamping hook 3-3, and then adjust the distance between the two clamping hooks 3-3. After the adjustment is completed, tighten the clamping hook fixing knob 3-2 to fix the clamping hook 3-3 so that it can cooperate with the back of the ankle 5, loosen the fixing knob 4-1, so that the ankle clamping nail 4 can change the pitch angle as needed at the lower end of the clamp handle 1, and after determining the angle, re-tighten the fixing knob 4-1 to clamp the ankle 5 for ankle reduction surgery.

[0026] In summary, the medial malleolus fracture reduction forceps of the utility model embodiment can clamp the ankle bone 5 in a triangular shape by two clamping hooks 3-3 with adjustable angles and spacings and an ankle bone clamping nail 4 with adjustable angles, can stably clamp the ankle bone 5 and control the reduction of the ankle bone 5 in a tiny incision, and can effectively improve the efficiency of the operation.
