Description

Technical Field

[0001] The utility model belongs to the technical field of surgical reduction forceps, and in particular relates to a surgical reduction forceps. Background Art

[0002] Reduction forceps, also known as bone holding forceps, are a type of medical device used to clamp bones and perform fixation and reduction in orthopedic surgery. They are usually composed of a forceps handle, a forceps head, and a branchial screw. The inner surface of the forceps head is often provided with teeth, and a locking device can be provided between the forceps handle. They are generally made of stainless steel. At present, the locking structure of orthopedic surgical reduction forceps generally adopts a screw and nut tightening method for fixing. However, this fixing method is relatively cumbersome during the operation, whether it is clamping or removing, which brings certain inconveniences to medical staff. Therefore, the utility model proposes a surgical reduction forceps, which can easily achieve the effect of clamping broken bones firmly, without the need for additional operating steps, simplifying the surgical operation process, and improving the convenience of the operation.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surgical reduction forceps comprises two forceps handles, the two forceps handles are symmetrically arranged, one end of the forceps handles is provided with a clamping part, and the other end of the forceps handles is provided with a gripping part, the two forceps handles are rotatably connected near the front end of the clamping part, and the two forceps handles are provided with a self-locking mechanism near the middle of the rotation connection, the self-locking mechanism comprises a locking rod and an opening, the bottom end of the locking rod body is rotatably connected to one of the forceps handles, the opening is opened on the other forceps handle, the locking rod body passes through the opening, a spring sheet is installed on one side of the locking rod body in the opening, and the other side of the locking rod body is evenly provided with latch teeth, and a locking device is provided on one side of the forceps handle located at the opening, and the locking device comprises a pressing paddle, the bottom of the pressing paddle is rotatably connected to the forceps handle, and a torsion spring is installed at the rotation connection, and the end of the pressing paddle is adapted to the latch teeth.

[0005] As a preferred technical solution of the utility model, the thickness of the pliers handle gradually decreases from the gripping portion to the clamping portion.

[0006] As a preferred technical solution of the utility model, clamping grooves are arranged inside the clamping parts of the two clamp handles, and the clamping grooves of the two clamp handles are symmetrically arranged.

[0007] As a preferred technical solution of the utility model, the inner side of the clamping groove of the clamping part of the clamp handle is evenly provided with retaining teeth.

[0008] As a preferred technical solution of the utility model, the pliers handle is provided with anti-slip patterns on the outer side of the gripping portion.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model sets a self-locking mechanism between the two clamp handles. During the operation, the medical staff only needs to hold the gripping part of the clamp handle until the broken bone is clamped and reset, and then the broken bone can be clamped and fixed. Compared with the traditional screw and nut tightening and fixing method, the utility model can easily achieve the effect of clamping the broken bone firmly without additional operation steps. This design not only simplifies the surgical operation process, but also improves the convenience of the operation, providing medical staff with more efficient and safe surgical tools.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] See also Figure 1-3The utility model provides the following technical solutions: a surgical reduction forceps, comprising two symmetrically arranged forceps handles 1; one end of each forceps handle 1 is equipped with a clamping portion 2, and the other end is provided with a gripping portion 3; the two forceps handles 1 are rotatably connected near the front end of the clamping portion 2, and the clamping portion 2 can be clamped by gripping the gripping portion 3; and a self-locking mechanism is provided in the middle near the rotation connection, which includes a locking rod 4 and an opening 5; the bottom end of the locking rod 4 is rotatably connected to one of the forceps handles 1, and the opening 5 is opened in the other forceps handle 1, the locking rod 4 passes through the opening 5; inside the opening 5, a spring sheet 6 is installed on one side of the locking rod 4; the other side of the locking rod 4 is evenly provided with latch teeth 7; on the pliers handle 1, a locking device 8 is also provided on the side close to the opening 5; the locking device 8 includes a pressing paddle 9, the bottom of which is rotatably connected to the pliers handle 1, and a torsion spring 10 is installed at the rotatable connection; the end of the pressing paddle 9 matches the design of the latch teeth 7, ensuring that the end of the pressing paddle 9 can be inserted between the latch teeth 7.

[0018] In order to ensure that the force is concentrated and to save effort when clamping broken bones, in this embodiment, as a preferred technical solution of the utility model, the thickness of the clamp handle 1 gradually decreases from the gripping part 3 to the clamping part 2.

[0019] In order to clamp the broken bone and increase the friction between the broken bone, in this embodiment, as a preferred technical solution of the utility model, a clamping groove 11 is provided on the inner side of the clamping part 2 of the two clamp handles 1, and the clamping grooves 11 of the two clamp handles 1 are symmetrically arranged, and retaining teeth 12 are evenly arranged on the inner side of the clamping groove 11 of the clamping part 2 of the clamp handle 1.
