Embodiment 1

[0045] figure 1 It is a schematic diagram of the assembly structure of the first fracture external fixation clip 170 provided in this embodiment, figure 2 A schematic diagram of the exploded structure of the first fracture external fixation clip 170 provided in this embodiment. Please refer to figure 1 and figure 2 , this embodiment provides a fracture external fixation clip 100 .

[0046] The fracture external fixation clip 100 includes a central insertion shaft 110 , a locking member 150 , a first clamping leg 120 and a second clamping leg 130 . Both the first clamping leg 120 and the second clamping leg 130 are connected to the central insertion shaft 110, and a clamping space 161 for clamping the bone is formed between the first clamping leg 120 and the second clamping leg 130. The first clamping leg 120 and the second clamping leg 130 directly extend into the body to clamp and fix the bone at the fracture site. It is easy to use, has small surgical wounds, and short...

Embodiment 2

[0070] image 3 It is a schematic diagram of the assembly structure of the second fracture external fixation clip 180 provided in this embodiment, Figure 4 It is a schematic diagram of the exploded structure of the second fracture external fixation clip 180 provided in this embodiment, Figure 5 The structure of the second clip leg 130' in the second fracture external fixation clip 180 provided by this embodiment. Please refer to Figure 1-Figure 5 , the present embodiment provides a second type of fracture external fixation clip 180, the second type of fracture external fixation clip 180 is roughly the same structure as the first type of fracture external fixation clip 170 provided in Embodiment 1, and the similarities will not be repeated. The difference is that the second clamping leg 130 ′ and the third clamping leg 140 are included.

[0071] The structure of the third clamping leg 140 is substantially the same as that of the first clamping leg 120. Specifically, the t...

Abstract

The embodiment of the invention provides a fracture external fixation clamp and a system thereof, and relates to the technical field of medical instruments. The fracture external fixation clamp provided by the embodiment of the invention comprises a central insertion shaft, a locking piece, a first clamping leg and a second clamping leg, wherein the first clamping leg and the second clamping leg are both connected to the central insertion shaft, and the clamping space used for clamping the bone is formed between the first clamping leg and the second clamping leg. In the using process, the first clamping leg and the second clamping leg can directly extend into the body to clamp and fix the bone at the fracture position, using is convenient, the surgical wound is small, the surgical time is short, meanwhile, after clamping, the size of the part, located outside the body, of the fracture external fixation clamp is far smaller than that of an existing fracture external fixation medical instrument, and influences on later rehabilitation activities of a patient can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fracture external fixation clip and a system thereof. Background technique [0002] The current clinical treatment of fractures can be divided into two types: internal fixation and external fixation. Internal fixation is to place a steel plate that fits the surface of the bone at the fracture site, and fix the plate and bone together with screws. After the bone at the fracture site is completely healed, the plate and screws are removed. This method of fixation has large surgical trauma, long operation time, and long recovery time in the later stage. The patient needs to undergo two operations and it is also more painful. The commonly used instruments for external fixation include plaster, splint, external fixator, etc. The advantage of external fixation is that the surgical incision is small, sometimes there is no surgical incision, the postoperative recovery is quicke...
