A locking volar oblique head type bone plate

Abstract

This application discloses a locking palmar oblique-head type bone plate, comprising a strip plate body and a palmar plate body formed at one end of the strip plate body. The end of the strip plate body away from the palmar plate body has a wedge-shaped body for easy implantation. The total length of the palmar plate body and the strip plate body is 183 mm. One end of the palmar plate body is slightly bent upwards. Both the front and back surfaces of the strip plate body are arc surfaces that conform to the bone surface. The radius of the arc on the front surface of the strip plate body is 20 mm, and the radius of the arc on the back surface is 22 mm. The strip plate body has multiple first threaded holes arranged along its extension direction. Blood supply grooves that promote bone healing are arranged on the back surface of the strip plate body, and these blood supply grooves are formed in pairs between adjacent first threaded holes. This utility model is designed with an extended type, so that only one bone plate is needed for effective fixation when the distal radius and radial shaft are fractured simultaneously.

Description

Technical Field

[0001] This application relates to bone plates, and more particularly to a locking palmar oblique head type bone plate. Background Technology

[0002] Most radial plates on the market are distal plates, which are relatively short. When the distal radius and the radial shaft are fractured simultaneously, they cannot be properly treated, and sometimes two plates are needed for fixation. This results in insufficient overall stability. Utility Model Content

[0003] The purpose of this invention is to provide a locking palmar-side oblique head type bone plate, which is designed with an extended bone plate to overcome the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution.

[0005] This application discloses a locking palmar oblique-head type bone plate, including a strip plate body and a palmar plate body formed at one end of the strip plate body. The end of the strip plate body away from the palmar plate body has a wedge-shaped body for easy implantation. The total length of the palmar plate body and the strip plate body is 183mm. One end of the palmar plate body is slightly bent upward. The front and back sides of the strip plate body are both arc surfaces that conform to the bone surface. The arc radius of the front side of the strip plate body is 20mm, and the arc radius of the back side of the strip plate body is 22mm. The strip plate body has a plurality of first threaded holes arranged along its extension direction. The back side of the strip plate body has blood supply grooves arranged to promote bone healing. The blood supply grooves are formed in pairs between two adjacent first threaded holes. The two ends of the strip plate body near the middle have shaping grooves. The surface of the palmar plate body has a plurality of second threaded holes.

[0006] Preferably, in the above-mentioned locking palmar-side beveled bone plate, the first threaded hole is an elongated hole for easy position adjustment.

[0007] Preferably, in the above-mentioned locking palmar oblique head type bone plate, Kirschner wire holes are provided on the palmar plate body and the strip plate body.

[0008] Preferably, in the above-mentioned locking palmar oblique head type bone plate, a cavity is formed at the connection between the palmar plate body and the strip plate body.

[0009] Preferably, in the above-mentioned locking palmar-side beveled type bone plate, the end of the strip plate away from the palm plate body is bent to one side.

[0010] Compared with existing technologies, the advantages of this technical solution are: by designing an extended type, only one bone plate is needed for effective fixation when the distal radius and the radial shaft are fractured at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Combination Figure 1-4As shown, the locking palmar oblique head type bone plate 100 includes a strip plate body 101 and a palmar plate body 102 formed at one end of the strip plate body 101. A wedge-shaped body 103 for easy implantation is formed at the end of the strip plate body 101 away from the palmar plate body 102. The total length of the palmar plate body 102 and the strip plate body 101 is 183 mm. One end of the palmar plate body 102 is slightly bent upwards. Both the front and back sides of the strip plate body 101 are arc-shaped surfaces that conform to the bone surface. The arc radius of the strip plate 101 is 20mm, and the arc radius of the back side of the strip plate 101 is 22mm. Multiple first threaded holes 104 are arranged along the extension direction of the strip plate 101. Blood supply grooves 105, which promote bone healing, are arranged on the back side of the strip plate 101. The blood supply grooves 105 are formed in pairs between adjacent first threaded holes 104. Shaping grooves 106 are formed at both ends of the strip plate 101 near the middle. Multiple second threaded holes 107 are formed on the surface of the palm plate 102. The first threaded holes 104 are elongated holes for easy position adjustment. Kirschner wire holes 108 are provided on the palm plate 102 and the strip plate 101. A cavity 109 is formed at the connection between the palm plate 102 and the strip plate 101. The end of the strip plate 101 away from the palm plate 102 is bent to one side.

[0018] In this embodiment, most radial plates on the market are distal plates, which are relatively short. This makes them unsuitable for treating simultaneous fractures of the distal radius and radial shaft, sometimes requiring two plates for fixation. This design, with its extended plate, effectively solves these problems. Both the front and back of this product feature rounded designs, conforming better to the bone surface and reducing foreign body sensation. The circular groove design on the back facilitates shaping while accelerating blood flow and promoting bone healing. This product utilizes a computer-generated titanium plate, achieving a perfect anatomical fit for a natural and aesthetically pleasing appearance. In specific implementation, an extended length of 183mm is used to ensure adequate treatment when simultaneous fractures of the distal radius and radial shaft are difficult to manage.

[0019] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
