[0002] Reduction forceps are an orthopedic surgical instrument typically consisting of two arms with a movable joint. By adjusting the position and angle of the forceps, the surgeon can apply force to reposition a bone or joint. These forceps feature strong jaws, a strong grip, and excellent plasticity, enabling them to accurately reposition fracture ends.

[0003] Reduction forceps come in a variety of shapes and structures for different bone or joint reduction surgeries. For example, Chinese utility model patent publication number CN 221750739U discloses a radial fracture reduction forceps with a flexible ring position that can be adjusted based on user needs and preferences, allowing medical personnel to find a more comfortable angle for operation and improving the device's effectiveness in the long term.

[0004] However, when using the reduction forceps, since the clamping part and the forceps arm are integrally formed, medical staff cannot flexibly replace the clamping part according to usage needs, which leads to a relatively limited scope of use of the reduction forceps and to a certain extent increases the cost of purchasing reduction forceps with various shapes and structures.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a reduction clamp.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 4 As shown, a reduction forceps in one embodiment of the present invention includes a pair of forceps arms 1 and a pair of clamping parts 2.

[0032] The pair of clamp arms 1 are hinged to each other, and a connecting portion 101 is fixedly connected to the clamp arm 1. The connecting portion 101 is used to install the clamping portion 2 so that the pair of clamping portions 2 can be used to clamp bones or joints.

[0033] In addition, an insertion groove 1011 is provided at the end of the connecting portion 101 to facilitate the insertion of the fixing portion 201 , thereby enabling the installation and fixation of the clamping portion 2 .

[0034] like Figures 1 to 4 As shown, a fixing mechanism is installed on the connecting portion 101, which can be used to quickly install and disassemble the clamping portion 2, so that medical staff can rotate different clamping portions 2 according to different usage requirements to increase the use range of the reduction forceps, and to a certain extent, reduce the cost of purchasing the clamp arm 1.

[0035] The fixing mechanism includes a protruding portion 1012 , which is integrally formed with the connecting portion 101 , and the protruding portion 1012 is used for installing a pin 1013 .

[0036] In addition, a pin 1013 is slidably connected to the protrusion 1012. When the pin 1013 is inserted into the fixing hole 202, the fixing portion 201 can be fixed in the insertion groove 1011, thereby fixing the connecting portion 101 and the clamping portion 2. When the pin 1013 is disengaged from the fixing hole 202, the fixing portion 201 can be removed from the insertion groove 1011 to replace the clamping portion 2.

[0037] Specifically, the side wall of the pin 1013 is connected to the limiting ring 1014, and a movable groove 1015 matching the limiting ring 1014 is provided in the connecting part 101, so that the limiting ring 1014 can move in the movable groove 1015 to achieve the engagement or separation of the pin 1013 and the fixing hole 202.

[0038] In addition, a spring 1016 is provided in the retaining ring 1014. The spring 1016 is provided outside the pin 1013 and contacts the retaining ring 1014. The retaining ring 1014 and the spring 1016 cooperate with each other to allow one end of the pin 1013 to be naturally inserted into the insertion groove 1011. That is, when the fixing portion 201 is inserted into the insertion groove 1011, the pin 1013 is inserted into the fixing hole 202, thereby achieving installation and fixation of the clamping portion 2, making it difficult for the clamping portion 2 to separate from the connecting portion 101.

[0039] like Figures 1 to 4 As shown, an elastic pad 1017 is embedded in the side wall of the insertion groove 1011. The elastic pad 1017 is made of rubber. The elastic pad 1017 can contact the fixing portion 201 so that the fixing portion 201 can be firmly fixed in the insertion groove 1011.

[0040] like Figures 1 to 4 As shown, one of the forceps arms 1 is fixedly connected to a hinge buckle 102, and a screw 103 is hingedly connected to the hinge buckle 102. The other forceps arm 1 is provided with a relief groove, and one end of the screw 103 passes through the relief groove, making it easier for medical personnel to hold the pair of forceps arms 1 and use the pair of clamping parts 2 to clamp bones or joints for reduction.

[0041] The screw 103 is threadedly connected to an adjusting nut 104, which is located at the end of the screw 103 away from the hinge clasp 102. The screw 103 and the adjusting nut 104 cooperate with each other to fix the opening distance between the pair of clamping parts 2, so that medical staff do not need to hold the pair of forceps arms 1 all the time.

[0042] like Figures 1 to 4 As shown, the clamping portion 2 is fixedly connected to the fixing portion 201. One end of the fixing portion 201 is inserted into the insertion slot 1011. The fixing portion 201 corresponds to the fixing mechanism. By inserting the fixing portion 201 into the insertion slot 1011 and then inserting the pin 1013 into the fixing hole 202, the clamping portion 2 can be installed on the connecting portion 101, ensuring the secure and stable installation of the clamping portion 2.

[0043] Preferably, this application is attached Figure 1 Two structures of the clamping portion 2 are shown, so that the clamp arm 1 can be adapted to clamping portions 2 of different shapes and structures, thereby expanding the overall application range of the clamp arm 1 and reducing the cost of purchasing the clamp arm 1 to a certain extent.

[0044] Among them, the side wall of the fixing part 201 is provided with a fixing hole 202, and one end of the pin 1013 is inserted into the fixing hole 202. When the pin 1013 is inserted into the fixing hole 202, the clamping part 2 can be installed on the connecting part 101, making it convenient for medical staff to use the reduction forceps as a whole.

[0045] In addition, a chamfer 203 is provided on the fixing portion 201 , and the chamfer 203 corresponds to the elastic pad 1017 , so as to facilitate better insertion of the fixing portion 201 into the insertion slot 1011 .

[0046] When in use, medical staff rotate the clamping part 2 according to the use requirements. Figure 1 Two shapes and structures of the clamping part 2 are shown. When installing the clamping part 2, first pull the pin 1013, and the limiting ring 1014 on the side wall of the pin 1013 will slide in the movable groove 1015 and compress the spring 1016, so that the limiting ring 1014 is completely received in the side wall of the connecting part 101.

[0047] The fixing portion 201 is aligned and inserted into the insertion slot 1011. The elastic pad 1017 exerts a compressive force on the fixing portion 201. The pin 1013 is released, and the pin 1013 returns to its original position under the cooperative action of the retaining ring 1014 and the spring 1016. That is, the pin 1013 extends into the insertion slot 1011 and is inserted into the fixing hole 202. At this point, the fixing portion 201 is fixed under the cooperative action of the pin 1013 and the elastic pad 1017, making it difficult for the fixing portion 201 to separate from the connecting portion 101, thereby completing the installation of the clamping portion 2.
