Description

Technical Field

[0001] This application relates to bone plates, and more particularly to a locking calcaneal anatomical bone plate. Background Technology

[0002] The calcaneus is the largest tarsal bone in the foot, located in the lower posterior part of the foot. It consists of the anterior part, body, tuberosity, talus suspensory process, and calcaneocuboid part. The anterior part includes the anterior talar articular surface and the calcaneocuboid articular surface. The medial cortex of the body is thicker and contains vascular and nerve passages. The tuberosity is the attachment point of the Achilles tendon. The talus suspensory process forms the midtalar articular surface. Below the calcaneocuboid part, there are dense pressure trabeculae that form the posterior articular surface with the talus. Together with the talus and cuboid bones, it forms four articular surfaces, of which the anterior, mid, and posterior talocalcaneal joints and the calcaneocuboid joint participate in foot movement.

[0003] Existing calcaneal plates often lack sufficient holding power and are not stable enough. Utility Model Content

[0004] The purpose of this invention is to provide a locking calcaneal anatomical bone plate, which proposes an encircling method to improve the reliability of calcaneal fracture treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] This application discloses a locking calcaneal anatomical bone plate, including an annular plate and a rectangular plate formed on one side of the annular plate. The annular plate has a plurality of first threaded holes arranged circumferentially thereon. A shaping groove is formed on both sides of the annular plate between two adjacent first threaded holes. A first arm plate is formed by protruding outward from the end of the annular plate away from the rectangular plate. A first arm plate is provided on the first arm plate. A second arm plate and a third arm plate are formed by protruding from the right side of the upper end and the left side of the lower end of the rectangular plate, respectively. A second arm plate and a third arm plate are provided on the second arm plate and the third arm plate, respectively. A plurality of second threaded holes are provided on the surface of the rectangular plate.

[0007] Preferably, in the above-mentioned locking calcaneal anatomical bone plate, the surfaces of the annular plate and the rectangular plate are arc-shaped, and the concave surface fits the calcaneus.

[0008] Preferably, in the above-mentioned locking calcaneal anatomical bone plate, Kirschner wire holes are respectively provided on the annular plate and the rectangular plate.

[0009] Preferably, in the above-mentioned locking calcaneal anatomical bone plate, the first threaded hole includes a locking hole and a normal hole.

[0010] Preferably, in the above-mentioned locking calcaneal anatomical bone plate, the second threaded hole includes a locking hole and a normal hole.

[0011] Preferably, in the above-mentioned locking calcaneal anatomical plate,

[0012] Compared with existing technologies, the advantages of this technical solution are: by extending the triangular surface, i.e., three arm plates, and connecting them with screws, the reliability of calcaneal treatment is improved. Attached Figure Description

[0017] 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.

[0018] Combination Figure 1-3As shown, the locking calcaneal anatomical bone plate 100 includes an annular plate 101 and a rectangular plate 102 formed on one side of the annular plate 101. The annular plate 101 has multiple first threaded holes 103 arranged circumferentially thereafter. Shaping grooves 104 are formed on both sides of the annular plate 101 between adjacent first threaded holes 103. A first arm plate 105 protrudes outward from the end of the annular plate 101 away from the rectangular plate 102, and a first arm plate 105 is provided on the first arm plate 105. A second arm plate 107 and a third arm plate 108 protrude from the right side of the upper end and the left side of the lower end of the rectangular plate 102, respectively. A second arm plate 109 and a third arm plate 110 are provided on the second arm plate 107 and the third arm plate 108, respectively. Multiple second threaded holes 111 are provided on the surface of the rectangular plate 102. The surfaces of the annular plate 101 and the rectangular plate 102 are arc-shaped, with concave surfaces conforming to the calcaneus. Kirschner wire holes 112 are respectively provided on the annular plate 101 and the rectangular plate 102. The first threaded hole 103 includes a locking hole and a normal hole. The second threaded hole 111 includes a locking hole and a normal hole.

[0019] In this embodiment, commercially available calcaneal plates are generally small in size and only suitable for specific types of fractures. In cases of comminuted fractures, two plates are sometimes required for fixation. This design features an extended and enlarged plate that can completely enclose the entire calcaneus, effectively solving these problems. The pre-formed design of this product significantly shortens surgical time. Its multi-porous design retains the micro-motion principle of the locking plate and allows for the selection of cancellous bone screws based on bone condition, greatly improving the product's holding power. Furthermore, this product utilizes a computer-generated digitally formed titanium plate, achieving a perfect anatomical fit and a natural aesthetic appearance.

[0020] This technical solution makes the treatment more secure by extending the triangular support, the gourd-shaped shaping groove improves the convenience of shaping, the anatomical lining design makes the fit to the bone surface higher, and the combination of locking holes and ordinary holes facilitates clinical selection.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely 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.
