Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a novel bone holder for small fractures. Background Technology

[0002] Bone holders are commonly used medical instruments in orthopedic surgery, primarily used to hold bones in place for reduction and fixation during fracture surgery. By providing stable fixation, they help maintain the fracture site in the correct position during the procedure, thus promoting fracture healing.

[0003] Existing orthopedic bone holders are mostly designed for large fractures such as the tibia, fibula, and femur, lacking options for smaller fractures. Bone holders used in large fracture surgeries typically employ a relatively rigid design to ensure force distribution and stability, failing to achieve a balance between rigidity and flexibility. Conversely, surgical instruments for small fracture surgeries generally do not require high rigidity but necessitate a degree of flexibility in the bone holder. Furthermore, bone holders designed for large fracture surgeries often have complex structures, making single-handed operation difficult. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a novel bone support for small fractures. To achieve the above objective, this invention adopts the following technical solution:

[0005] A novel small fracture bone holder includes two opposing clamping arms, which are hinged together. The clamping arms form a clamping part above the hinge position and a hand-held part below the hinge position.

[0006] The clamping part includes a curved arm that bends outward and a clamping head disposed on the curved arm, the surface of which is provided with a groove;

[0007] The handheld part is equipped with a limit lock.

[0008] As an improvement, the clamping head has a flat section at the top and an arc-shaped section at the bottom, so that the clamping head gradually contracts downwards.

[0009] As an improvement, the groove is positioned perpendicular to the clamping head.

[0010] As an improvement, the limiting latch includes a long locking plate and a short locking plate, which are respectively disposed on two clamping arms;

[0011] The long and short card plates are provided with mutually cooperating card blocks and card slots;

[0012] The clamping arm with the short card plate has a second groove for the long card plate to pass through.

[0013] As an improvement, the end of the clamping arm is provided with a ring handle for the hand to pass through.

[0014] The advantages of this utility model are:

[0015] 1. This utility model has a curved arm on the clamping part, which can effectively increase the toughness of the clamping part of the bone holder. With the limit lock of the hand part, after the limit lock is locked, the clamping point can be moderately pressed by the toughness of the curved arm, so that the fracture site is tightly pressed, thereby improving the success rate of bone setting and improving the bone healing effect.

[0016] 2. The clamping head of this utility model can effectively increase the friction between the clamping head and the bone, improve the clamping effect, and prevent relative slippage during the clamping process.

[0017] 3. The present invention has a simple and reasonable structure, and the limiting lock is easy to operate. The entire device can be operated with one hand, which facilitates adjustment during fracture fixation and frees the surgeon's hand, making it easier and faster to complete fracture fixation.
