Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

The first embodiment:

referring to fig. 1, an improved bone traction arch, comprising: the suspension plate comprises a suspension plate 1, a connecting piece 2, a first traction arm 3 and a second traction arm 4, wherein the first traction arm 3 and the second traction arm 4 are symmetrically arranged on the connecting piece 2 and are respectively hinged with the connecting piece 2; and the fixing nails 5 are respectively arranged at the movable ends of the first traction arm 3 and the second traction arm 4.

In the embodiment, the first traction arm 3 and the second traction arm 4 are respectively and independently hinged on the connecting piece 2, and each traction arm can independently move. The movable end of each traction arm is provided with a fixing nail base, the base body is in a bolt shape and penetrates through the axial direction of the base body to form a through hole for inserting a fixing nail. When the traction bow is used, holes are respectively drilled from two sides of the bone at the traction part, and the fixing nails penetrate through the through holes of the base of the traction arm to respectively fix the bone to be dragged from two sides. The fixing mode does not need to penetrate through bones, two sides of the fixing mode are separately positioned and fixed, and the problems that the traditional Kirschner wire is high in operation precision requirement, prone to drilling deviation and the like are solved. Simultaneously, the traction arm which moves independently can be independently fixed from two sides, one side is fixed and the other side is fixed during operation, and the operation is more convenient.

Preferably, the width of the suspension plate is 6cm, and the distance between the two hinged ends of the connecting piece is 9cm, so that the standard size of the traction bow is met. The whole arc that is of trailing arm, the human surface radian of laminating more easily of arc structure can not too much oppress the skin, can set up different sizes according to the actual demand simultaneously, satisfies the traction treatment of different positions such as skull, shin bone.

Furthermore, fastening devices (6) are respectively arranged at the joints of the first traction arm (3), the second traction arm (4) and the connecting piece (2).

In the embodiment, fastening devices are arranged at the hinged parts of the first traction arm 3 and the second traction arm 4 and the connecting piece 2, when the traction arms are adjusted to a proper angle, the traction arms can be locked by screwing the fastening devices, and the traction arms cannot rotate after being locked, so that the influence of shaking on the traction effect in the use process is avoided. When in use, the angle of one or two traction arms can be adjusted in advance according to the size of the traction part and locked by the fastening device, and then the traction bow is fixed to the traction part.

Furthermore, the connecting piece 2 is of an arc-shaped structure and is integrally formed with the suspension plate 1.

Preferably, the connecting piece 2 is of an arc-shaped structure, the arc-shaped structure is easier to fit with the radian of the surface of a human body, the skin cannot be pressed too much, the arc-shaped structure is simpler to process, and the cleaning is more sanitary due to the fact that no corner or other gaps exist during cleaning. Meanwhile, different sizes can be set according to actual requirements, the radian of different parts can be better fitted, and the traction treatment of different parts such as the skull, the tibia and the like can be met. The arc design main function is the laminating human body, improves the comfort level, can be applied to the use of pulling at a plurality of positions of human body simultaneously, does not influence holistic effect of pulling. The suspension plate 1 and the connecting piece 2 are integrally formed, the size is relatively fixed, the operation is more convenient, and the suspension plate cannot be loosened during traction.

In other embodiments the trailing arm and the link 2 may be arranged in other shapes, such as straight lines or right angles, as shown in fig. 2 and 3.

Second embodiment:

referring to fig. 4, the connector 2 includes a fixing rod 21 and two sliding connection rods 22, and the sliding connection rods 22 are slidably connected to the fixing rod 21.
