The internal fixation tail enters the insertion hole 102 and further enters the inside of the housing 101, and the internal fixation tail is bent inside the housing 101.
The housing 101 includes a first assembly portion and a second assembly portion, which can be spliced together to form the complete housing 101. Further, the first combination portion and the second combination portion are axially combined, and a boundary line of the first combination portion and the second combination portion is along the axial direction of the housing 101.
In some examples, the internal fixation tails curve in an arc in a certain direction within the housing 101, i.e., the center of gravity of the internal fixation assembly is offset in the direction of the curve. In order to save labor during the insertion process of medical staff and prevent internal fixation movement, the position of the projection center of the shell 101 is properly deviated in the bending direction. Since the insertion hole 102 is not bent at the time of internal fixation, the projection position of the insertion hole 102 is deviated from the center of the cross section of the housing 101 in the direction opposite to the bending direction, that is, the projection center of the housing 101 is deviated in the bending direction.
In some examples, a portion of the housing 101 near the insertion hole 102 has a gradually decreasing cross-sectional area, and the cross-sectional area is smallest at the insertion hole 102.

The shaping channel 103 is disposed inside the housing 101, and the shaping channel 103 is used for bending the inner fixing tail into a set shape. It will be appreciated that the shaped passage 103 communicates with the insertion hole 102, and the inner fixing tail enters the shaped passage 103 when entering the inside of the housing 101. The internal fixation increases in the course of gradually entering the housing 101, the internal fixation length within the housing 101 increases, and the internal fixation extends along the shaping channel 103 towards the inside of the housing 101.
In some examples, by setting a specific shape of the sizing channel 103, it can be ensured that the internal fixation tail passing through the sizing channel 103 is sized into a corresponding shape, and then the length of the internal fixation tail is set according to actual conditions.
Further, in order to form the shape of the internal fixation tail into a smooth arc and prevent the internal fixation tail from damaging human tissues, the shaping channel 103 is arc-shaped inside the shell 101, and the internal fixation tail is shaped into an arc when passing through the shaping channel 103; design passageway 103 extends to the position that is close to patchhole 102, guarantees that the internal fixation afterbody passes through the arc and stereotypes the back, and the afterbody returns to the position that is close to the straight part of internal fixation to avoid the internal fixation afterbody sharp-pointed part to appear, damage human tissue.
Specifically, the shaping channel 103 is a pipeline arranged inside the housing 101, and the inner fixing tail part completes shaping through the pipeline; or the shaping channel 103 is provided as a groove on the first combination part and the second combination part, and the inner fixing tail part is shaped by the limitation of the groove.
