[0048] refer to Figure 1 ~ Figure 3 , the present embodiment provides a bone plate, the bone plate includes a bone positioning part 1, which matches the shape of the part to be boned; The two sides are used to surround and fix the bone-synthesis site;

[0049] All the embracing arms are divided into two groups, the first embracing arm group 2a located on one side of the bone positioning part 1 and the second embracing arm group 2b located on the other side of the bone positioning part 1;

[0050] The bone positioning part 1 is divided into at least two sub-positioning parts 10, among the two sub-positioning parts 10 connected to each other, one of the sub-positioning parts 10 has an accommodation space 11, and the other sub-positioning part 10 has an insert 12, and the insert 12 is inserted into the accommodation space After 11, the two sub-positioning parts 10 are fixedly connected, and the insert 12 can be pulled out from the accommodating space 11.

[0076] Compared with the first embodiment, the differences of this embodiment are:

[0077] refer to Figure 4 , the first embracing arm set 2a' includes two first embracing arms 21', and the second embracing arm set 2b' includes two second embracing arms 22'. This can meet the need for embracing when the length of the bone-synthesized part is long, and multiple embracing arms are integrally fixed on the corresponding sub-positioning parts, the structure is compact, and the installation and disassembly save time and effort.

[0078] refer to Figure 4, the first sub-positioning part 10a' has a fixed end C, the inserts 12' are fixed on the fixed end C, and the two first embracing arms 21' in the first embracing arm group 2a' are fixed on the fixed end C. The first embracing arm 21 ′ includes an extension portion 210 and an embracing portion 211 , the extension portion 210 is fixed on the first sub-positioning portion 10 a, and the embracing portion 211 is used for embracing a...

Abstract

A bone plate comprises a bone positioning part and at least two embracing arms, wherein the bone positioning part is matched with the shape of to-be-set bone part; the embracing arms are connected with the bone positioning part, located on two sides of the bone positioning part and used for embracing and fixing the to-be-set bone part; all the embracing arms are divided into two groups including a first embracing arm group located on one side of the bone positioning part and a second embracing arm group located on the other side of the bone positioning part; the bone positioning part is at least divided into two auxiliary positioning parts which are mutually connected, one auxiliary positioning part is provided with accommodating space, the other auxiliary positioning part is provided with an insertion piece, the two auxiliary positioning parts are fixedly connected after the insertion piece is inserted into the accommodating space, and the insertion piece can be pulled out from the accommodating space. According to the bone plate in the scheme, the two auxiliary positioning parts in the connecting state require no external assistant connection pieces, the bone plate is simple in structure and quite convenient to mount and dismount, a short time is consumed, and surgical risks are reduced accordingly.
