Description

Technical Field

[0001] The invention relates to the field of bone surgical instruments, and in particular to a universal surgical fixation titanium plate used for fixing adjacent bone ends in various fracture or osteotomy operations. Background Art

[0002] Surgical fixation titanium plates are currently commonly used medical devices for bone surgery. They are widely used for splicing, resetting, and other types of fractures and osteotomy ends to facilitate normal bone healing. When it comes to complex bone structure fractures or complex multi-bone fractures, a variety of titanium plates of different shapes that are adapted to different bone positions are required. Therefore, the various types of structures developed by relevant medical device companies still cannot meet the needs of some rare and special fractures. Generally, when the clinic encounters a situation where it is impossible to find a suitable titanium plate, it will ask the relevant company to customize it, which is time-consuming and labor-intensive, delays treatment opportunities, and also wastes the human costs of the medical device company. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a universal surgical fixation titanium plate in view of the deficiencies in the prior art.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a universal surgical fixation titanium plate, comprising a plurality of titanium plate bodies and connecting bolts, wherein a plurality of through holes are provided on the titanium plate bodies, and the plurality of titanium plate bodies are hingedly connected by connecting bolts passing through the through holes;

[0005] The titanium plate body is provided with a limiting structure to limit the opening and closing angle between any two titanium plate bodies.

[0006] The beneficial effect of the present invention is that by opening a through hole on the titanium plate body and setting a limiting structure on the titanium plate body, the present invention can adapt and insert the bolts on the two titanium plate bodies that need to be connected, and can realize the splicing and forming of multiple titanium plate bodies to meet different fracture needs and adapt to the needs of clinical individualization.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the opening and closing angle is 45°-120°.

[0009] Furthermore, the titanium plate body is a long plate-like structure, and the limiting structure is a plurality of recessed structures opened on one side of the titanium plate body, and the plurality of recessed structures are arranged in a row along the length direction of the titanium plate body, and the plurality of through holes are opened one by one at the bottom of the plurality of recessed structures; the recessed structures on the two titanium plate bodies are crimped to each other to limit the opening and closing angle between the two connected titanium plate bodies.

[0010] The beneficial effect of adopting the above further solution is that by providing a recessed structure on the titanium plate body, the limited hinge connection between the two connected titanium plate bodies can be facilitated.

[0011] Furthermore, the two sides of the recessed structure are open and are penetrated on the titanium plate body along the width direction of the titanium plate body.

[0012] The beneficial effect of adopting the above further solution is that by setting the two sides of the recessed structure to be open, the thickness of the connecting portion of the two titanium plate bodies can be made equal to the thickness of a single titanium plate body.

[0013] Furthermore, the width of the recessed structure along the length direction of the titanium plate body is greater than the width of the titanium plate body.

[0014] Furthermore, the middle portions of the two side walls of the recessed structure are both in an arc-shaped structure protruding toward the corresponding through holes opened at the bottom thereof.

[0015] The beneficial effect of adopting the above further scheme is: by setting the two side walls of the recessed structure into an arc structure, the two hinged titanium plate bodies can rotate along the arc structure by a certain angle, which facilitates the adjustment of the fixing method of the titanium plate body on the human skeleton.

[0016] Furthermore, the depth of the recessed structure is equal to 1 / 2 of the thickness of the titanium plate body.

[0017] The beneficial effect of adopting the above further solution is that by limiting the depth of the recessed structure, after the two titanium plate bodies are connected, the thickness of the connecting portion can be equal to the thickness of a single titanium plate body.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2As shown, a universal surgical fixation titanium plate of this embodiment includes multiple titanium plate bodies 1 and connecting bolts. The titanium plate body 1 is provided with multiple through holes 11, and the multiple titanium plate bodies 1 are hinged by connecting bolts inserted into the through holes 11; a limiting structure is provided on the titanium plate body 1 to limit the opening and closing angle between any two connected titanium plate bodies 1. In this embodiment, by providing through holes on the titanium plate body and setting a limiting structure on the titanium plate body, the bolts can be adapted and plugged into the two titanium plate bodies that need to be connected, and multiple titanium plate bodies can be spliced ​​and formed to meet different fracture needs and adapt to clinical individual needs.

[0024] The opening and closing angle of the present embodiment is 45°-120°. By reasonably limiting the opening and closing angle between the two connected titanium plate bodies, the possibility of shape change between the titanium plate bodies can be increased.

[0025] like Figure 1 As shown, the titanium plate body 1 of this embodiment is a long strip-shaped structure, and the limiting structure is a plurality of recessed structures 12 opened on one side of the titanium plate body 1, and the plurality of recessed structures 12 are arranged in a row along the length direction of the titanium plate body 1, and the plurality of through holes 11 are opened at the bottom of the plurality of recessed structures 12 in a one-to-one correspondence; the recessed structures 12 on the two titanium plate bodies 1 are pressed against each other to limit the opening and closing angle between the two connected titanium plate bodies 1. For example, the two titanium plate bodies are superimposed on each other into a cross structure, and then the recessed structure of one titanium plate body is inserted into the recessed structure on the other titanium plate body. At this time, the opening and closing angles of the two titanium plate bodies are limited by the side walls of the recessed structures, which, on the one hand, avoids the thickness of the connection between the two titanium plate bodies being too thick to affect the use effect, and on the other hand, avoids the opening and closing angles between the titanium plate bodies being too large to be inconvenient to operate during actual surgery.

[0026] like Figure 1 As shown, the two sides of the recessed structure 12 of this embodiment are open and are arranged on the titanium plate body 1 along the width direction of the titanium plate body 1. By setting the two sides of the recessed structure to be open, it is convenient for the recessed structures of the two titanium plate bodies to be mutually engaged. The width of the recessed structure 12 along the length direction of the titanium plate body 1 is greater than the width of the titanium plate body 1.

[0027] like Figure 1 As shown, the middle of the two side walls of the recessed structure 12 of this embodiment are both arc-shaped structures protruding toward the corresponding through hole 11 at the bottom thereof. By setting the two side walls of the recessed structure into an arc-shaped structure, the two titanium plate bodies after being hinged can be rotated along the arc-shaped structure by a certain angle, so as to facilitate the adjustment of the fixing method of the titanium plate body on the human skeleton.

[0028] like Figure 2As shown, the depth of the recessed structure 12 in this embodiment is equal to 1 / 2 of the thickness of the titanium plate body 1. By limiting the depth of the recessed structure, the thickness of the connecting portion after two titanium plate bodies are connected can be equal to the thickness of one titanium plate body.

[0029] The process of using the universal surgical fixation titanium plate of this embodiment is to first select the appropriate titanium plate body and the number of titanium plate bodies according to the actual fracture and osteotomy end, and then fix the titanium plate body and the human bone according to the actual situation. If the bone injury surface is too large, multiple titanium plate bodies can be used to form a mesh structure fixed net after being locked and fixed by bolts to achieve the purpose of fixing the fracture or osteotomy end.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
