[0019] The utility model will be further explained in detail in connection with the drawings and implementation:

[0020] As Figure 1 Indicated, a new type of metacarpal phalangeal fracture reduction instrument, including clamp handle 1, clamp head 2 and limiting device 3, clamp head 2 is arranged on clamp handle 1, clamp head 2 is provided with multiple pincers 4, the gripping surface of pincers 4 is provided with anti-slip structure 5, limiting device 3 is arranged on clamp handle 1, and clamp handle 1 can be locked. Wherein clamp head 2 part length 40mm, clamp handle 1 part length 120mm, the size is more suitable for the reduction of metacarpal phalangeal bone.

[0021] As one of the embodiments of the utility model, clamp head 2 is provided with three pincers 4, the width of pincers 4 is 5mm, the interval between two pincers 4 is 5mm, and tooth-shaped anti-slip structure 5 is arranged on pincers 4, is grabbed by multiple pincers 4, so that the utility model discloses more easily hold metacarpal phalangeal bone this kind of small and narrow bone, and the dispersed pincers 4 can increase the friction force when clamping, more firmly grab metacarpal phalangeal bone, and the anti-slip structure 5 arranged on pincers 4 makes the utility model discloses clamping stable, not easy to slide and affect reduction effect.

[0022] As Figure 2 shown, as one of the embodiments of the utility model, the limiting device 3 includes the threaded rod 6 and the knob 7, one end of the threaded rod 6 is hinged to one of the handles 1, the other end passes through the perforation 8 set up on the other handle 1, the knob 7 is screwed on the threaded rod 6, and the handle 1 is clamped and fixed by the knob 7. By screwing the knob 7, the knob 7 and the threaded rod 6 are matched to clamp and fix the handle 1, which is beneficial to reset and maintain, and does not need external force to maintain reset, which is convenient for the surgeon to implant the internal fixation device to complete the operation. The knob 7 is provided with the anti-skid knurl 9, which is not easy to slip and reduces the risk of operation.

[0023] As Figure 3 shown, as one of the embodiments of the utility model, the limiting device 3 includes the ratchet plate 10, the ratchet plate 10 is provided with a plurality of pawls 11, and the two handles 1 are respectively provided with the ratchet plate 10. The two ratchet plates 10 are buckled relative to each other, and the pawls 11 are embedded relative to each other. Due to the characteristics of the pawls 11, when the utility model is clamped, the two ratchet plates 10 can be smoothly slid relative to each other to complete the clamping action. When the doctor holds the bone, the pawl 11 is not easy to retreat, and at this time, the handle 1 has a certain pre-tightening force, which stably clamps and maintains the reset of the bone, and is convenient for the surgeon to implant the internal fixation device to complete the operation.
