Description

Locking tibia inner side hook plate

Technical Field

The present application relates to medical devices, and more particularly to a locking tibial medial hook plate.

Background

The proximal tibial mediastinum plates on the market are many, but are generally flat plates and need to be locked by screws.

Disclosure of Invention

The invention aims to provide a hook plate for locking the inner side of a tibia, which is designed to be in a distal end pointed hook shape, so that a fracture end can be firmly held, and fracture blocks are prevented from dissociating.

In order to achieve the above object, the present invention provides the following technical solutions.

The embodiment of the application discloses locking shin bone inboard hook plate, the package rubbing board body, the one end of plate body is protruding to stretch side by side and is formed with two hook bodies, two be formed with the elongated slot between the hook body, the other end surface of plate body is formed with the locking hole, the middle part surface of plate body is formed with long type hole, long type hole with be formed with the kirschner wire hole between the locking hole.

Preferably, in the above-described locking tibia medial hook plate, the top of the hook body is formed with a sharp corner.

Preferably, in the above-described locking tibia inside hook plate, the cusp protrudes toward the locking hole.

Preferably, in the above mentioned locking tibia inner hook plate, the inner arc surface formed by the hook body is fitted to the bone surface.

Preferably, in the above locking tibia inside hook plate, the top surface outer periphery of the plate body is formed with a chamfered slope.

Preferably, in the above-described locking tibial medial hook plate, the elongated slot extends to be adjacent to the elongated hole.

Preferably, in the above-described locking tibial medial hook plate, the locking hole is a counter-bore design.

Preferably, in the locking tibia inner side hook plate, two sides of the plate body at the kirschner pin hole are formed with concaves.

Compared with the prior art, the invention has the advantages that the invention designs the hook-shaped distal end, can firmly hold the fracture end and prevent the fracture block from dissociating.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the locking tibia inside hook plate includes a plate body 100, two hook bodies 101 are formed at one end of the plate body 100 in a protruding manner side by side, an elongated slot 102 is formed between the two hook bodies 101, a locking hole 103 is formed on the surface of the other end of the plate body 100, an elongated hole 104 is formed on the surface of the middle portion of the plate body 100, and a k-wire hole 105 is formed between the elongated hole 104 and the locking hole 103. Slot 102 extends to near elongated hole 104.

In the embodiment, the hook-shaped distal tip is designed to firmly hold the fracture end and prevent fracture block from dissociating. The kirschner wire holes are used for temporarily fixing the bone fracture plate, and the long holes are designed to facilitate the adjustment of the position of the bone fracture plate in the operation; and the long groove is designed to be overlong, so that the stress is dispersed.

Further, the top of the hook 101 is formed with a sharp corner 106. The pointed corner 106 projects in the direction of the locking hole 103.

In this embodiment, it is made to hold the fracture end firmly.

Further, the hook 101 forms an inner arc surface to be fitted to the bone surface.

In the embodiment, the radian is dissected, the bone surface is perfectly attached, and the effect is improved.

Further, a chamfer slope 107 is formed on the periphery of the top surface of the plate body 100.

In this embodiment, the sheet thickness is reduced, reducing soft tissue irritation.

Further, the locking hole 103 is a counterbore design.

In this embodiment, the locking nail and the normal nail are satisfied at the same time.

Further, the plate body 100 is formed with recesses 108 on both sides of the k-wire hole 105.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrases "comprising a," "8230," "8230," or "comprising" does not exclude the presence of additional like elements in a process, method, article, or apparatus that comprises the element.
