Embodiment 1

[0028] Please refer to figure 1 , This embodiment provides a bridge locking plate, including a plate body 1-6 and a plurality of locking holes 1-4 arranged on the plate body 1-6, the plurality of locking holes 1-4 along the plate body 1-6 The longitudinal direction is distributed on both sides of the fracture line 1-3 to form a bridge structure; among them, the bridge structure is a single bridge type. Specifically, such as figure 1 As shown, there are two locking holes 1-4 on each of the longitudinal ends of the plate body 1-6. The plate body between the locking holes at both ends spans the fracture area 1-5, like a bridge, connecting the normal bones at both ends Part 1-1, 1-2. Generally, the locking plate in this embodiment is used to treat comminuted fractures or shaft fractures with multiple fractures and thick surrounding muscles. Because of the partial loss of the original mechanical strength of this type of fracture, it is difficult to use screws to fix the plate throu...

Embodiment 2

[0032] Please refer to Figure 2 to Figure 3 , The bridge locking plate provided in this embodiment has a double bridge type of bridge structure; specifically, it is provided with multiple or more groups of locking holes 1-4 in the longitudinal direction of the plate body 1-6, multiple or more groups The locking holes 1-4 are distributed on the longitudinal ends of the plate body 1-6 and the middle part of the plate body 1-6, and there is a fracture between the locking hole at each of the longitudinal ends and the locking hole in the middle part respectively. Line 1-3. Such as figure 2 As shown, the longitudinal ends of the plate body 1-6 are respectively provided with two locking holes 1-4, the middle part of the plate body 1-6 is provided with two locking holes 1-4, each of the longitudinal ends is locked There is a fracture line 1-3 between the hole and the locking hole of the middle part respectively. Of course, the number of locking holes in the middle part can also be d...

Embodiment 3

[0036] Please refer to Figure 4 , The bridge locking plate provided by this embodiment has a multi-bridge type of bridge structure; specifically, two locking holes 1-4 are provided at both longitudinal ends of the plate body 1-6, and the middle part of the plate body 1-6 is provided There are two locking holes 1-4, a fracture line 1-3 is corresponding between the two locking holes in the middle part, and the locking hole at each end of the longitudinal ends corresponds to the locking hole in the middle part near the end There is 1 fracture line 1-3.

[0037] Generally, the fractures that the locking plate is used to treat are between comminuted fractures and transverse fractures. Because of the mechanical strength of this kind of fracture block, the mechanical strength is higher than the strength of comminuted fracture, and the size is not enough to accommodate more than two screws. Therefore, the locking hole in the middle part of the plate is a single locking hole.

Abstract

The invention discloses bridging locking plate and belongs to the field of medical instruments. The bridging locking plate comprises a plate body and a plurality of locking holes arranged in the plate body, wherein the locking holes are distributed on two sides of a fracture line along the longitudinal direction of the plate body to form a bridging structure, and the bridging structure is a single-bridging type structure, a double-bridging type structure or a multi-bridging type structure. The bridging locking plate has the advantages that corresponding types of bridging locking plates can be provided according to different fracture types and positions, the locking holes are not located at a fracture position, the equivalent bending strength of a bone plate after surgery is increased, the fatigue service life of the bone plate is prolonged, and the safety and effectiveness of a steel plate and a facture block are guaranteed.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and particularly relates to a bridge locking plate. Background technique [0002] At present, in the treatment of fractures, bone screws are generally used to pass through the through holes on the bone plate to fix the bone plate across the fracture line, and to temporarily strengthen the fixation of the fracture site. Due to the randomness of the fracture location, the location of the fracture line and the direction of the fracture line depend on the person and the injury state. The existing bone plates are designed with corresponding positioning structures according to the specificity of the bones in different parts of the human body. The positions of the faces on the bone plates are all equidistantly distributed along the longitudinal axis of the bone plates, that is, any two adjacent The distance between the holes of the through holes is equal. Therefore, there is a high possibility that the fra...
