[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way.
[0023] See Figure 1-5 Orthopedic reduction forceps include forceps heads 1, which are symmetrically arranged. One end of each forceps head 1 is pointed. A first connecting block 2 is fixed to the other end of one forceps head 1, and a second connecting block 201 is fixed to the other end of the other forceps head 1. The first connecting block 2 and the second connecting block 201 are rotatably connected by a pin. The other ends of the first connecting block 2 and the second connecting block 201 are respectively fixed to one end of a forceps handle 3. The other end of the forceps handle 3 is respectively fixed to a hand ring 5.
[0024] The first connecting block 2 and the second connecting block 201 are rotatably connected by a pin, forming a lever fulcrum. When the doctor grasps the hand ring 5 and applies external force, the force is transmitted through the forceps handle 3 to the first connecting block 2 and the second connecting block 201, thereby driving the symmetrically arranged forceps heads 1 to open and close, thus grasping and reducing the fracture site.
[0025] The other end of the clamp handle 3 is fixedly connected to the limiting strip 4. The two limiting strips 4 are arranged opposite to each other and abut against each other. The other end of the clamp handle 3 is provided with a groove 301 corresponding to the position of the limiting strip 4, and the limiting strip 4 can be placed in the groove 301.
[0026] The limiting strip 4 can move along the groove 301 with the clamp handle 3, thereby increasing stability and providing limiting support to a certain extent.
[0027] Each of the limiting bars 4 includes an arc-shaped rod 401 and a serration 402. The arc-shaped rod 401 fixes the clamp handle 3. The opposite side of the arc-shaped rod 401 is planar and is fixed with a set of evenly arranged serrations 402. Adjacent serrations 402 form a slot, and the corresponding serration 402 can be inserted into the slot.
[0028] In this embodiment, the limiting strip 4 is pried open to both sides to disengage the serration 402 from the slot (the serration 402 disengaging from the slot will not cause the limiting strip 4 to break, and the limiting strip 4 is within the deformable range). The hand ring 5 is manually pulled to move the pliers handle 3, which in turn moves the limiting strip 4. The angle between the pliers handle 3 is adjusted to achieve the opening angle between the pliers heads 1. After adjustment, the limiting strip 4 is released so that the serration 402 of the limiting strip 4 re-engages into the slot, thereby limiting the limiting strip 4.
[0029] The serrations 402 on the opposite side of the arc-shaped rod 401 on the limiting strip 4 cooperate with the slot. When it is necessary to fix the opening degree of the pliers 1, the serrations 402 on the two limiting strips 4 are engaged into the corresponding slots. By using the meshing action of the serrations 402 and the slots, the further opening and closing of the pliers 1 is restricted, thereby achieving the limiting function.
[0030] The pliers head 1 includes a connecting part 100, a working part 101, a connecting rod 102, a limiting groove 103, a fixing block 104, a stop block 105, a set screw 106, a threaded hole 107, a moving rod 108, and a round shaft 109. One end of the connecting part 100 is fixedly connected to the connecting block, and the other end of the connecting part 100 is connected to the working part 101.
[0031] The arc-shaped wall surface at the other end of the connecting part 100 is fixedly connected to the fixing block 104. Limiting grooves 103 are respectively formed at the other end of the connecting part 100. Each limiting groove 103 has two ends rotatably connected to one end of the working part 101. The working part 101 is L-shaped, and two pairs of working parts 101 are symmetrically arranged. The outer end of each working part 101 is pointed. The lower middle part of one side of each working part 101 is rotatably connected to one end of the connecting rod 102. One of the connecting rods 102 in each pair... The other end of 02 is fixedly connected to the circular shaft 109. The circular shaft 109 is rotatably connected to the other end of another corresponding connecting rod 102. The circular shaft 109 is rotatably connected to one end of the moving rod 108. The moving rod 108 passes through the fixed block 104. The moving rod 108 is provided with a plurality of evenly arranged threaded holes 107. The moving rod 108 is slidably connected to the fixed block 104. The other end of the moving rod 108 is fixedly provided with a stop block 105. The diameter of the stop block 105 is larger than the diameter of the moving rod 108.
[0032] After the bolt (106) passes through the through hole on one side of the fixing block 104, it is threaded to connect to the threaded hole 107.
[0033] In this embodiment, when it is necessary to adjust the angle of the working part 101, loosen the bolt 106 that passes through the through hole of the fixing block 104 and engages with the threaded hole 107 on the moving rod 108, remove it, and then move the moving rod 108. The moving rod 108 drives the working part 101 to rotate around the rotation point in the limiting groove 103 through the connecting rod 102, thereby changing the angle of the working part 101. After adjusting to the appropriate position, tighten the bolt 106 to fix the moving rod 108, so that the working part 101 is kept at the required angle. The opening angle of each pair of working parts 101 can be adjusted, and the working part 101 has multiple gripping points, resulting in a better gripping effect.
[0034] The working process of this utility model is as follows: The doctor holds the hand ring 5 of the reduction forceps. If it is necessary to adjust the angle of the working part 101 of the forceps head 1, loosen the bolt (106), move the moving rod 108, adjust the working part 101 to a suitable angle, and then tighten the bolt (106) to fix it. Align the sharp forceps head 1 with the fracture site and slowly apply external force to close the forceps head 1. The forceps handle 3 will drive the limiting strip 4 to move. The limiting strip 4 moves from the groove 301 and drives the saw teeth 402 to move along the slot. During this process, the saw teeth 402 undergoes elastic deformation. After the forceps head 1 clamps the fracture fragment, the forceps head 1 hooks the fracture fragment and limits the two sides of the fracture site. The forceps handle 3 no longer moves. The saw teeth 402 are inserted into the corresponding slot to achieve the limiting.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present invention shall still fall within the scope of the present utility model.
