技术领域technical field
本发明属于医疗器械领域，涉及一种股骨远端骨折后骨不连翻修手术时使用的钢板。The invention belongs to the field of medical devices and relates to a steel plate used in revision surgery of nonunion after distal femur fracture.
背景技术Background technique
股骨远端骨折约占全身骨折的6%，为临近关节骨折，保守治疗效果较差，绝大多数学者提倡手术治疗，经外侧入路解剖锁定钢板内固定，逐渐成为治疗股骨远端骨折经典的内固定方法。虽然手术治疗取得了良好的效果，但术后骨不连，内固定断裂文献中时有报道。对于内固定断裂的患者，再次行翻修手术时，由于外侧钢板为解剖锁定板，再次选择同一类型钢板时，往往会放置在与第一次手术相同位置。由于钢板放置于相同位置，锁定钉也会置于与第一次手术相同位置，这就会导致固定不牢固，甚至再次手术失败的问题。Fractures of the distal femur account for about 6% of all fractures in the whole body. They are fractures near the joint, and the conservative treatment effect is poor. Most scholars advocate surgical treatment. Anatomical locking plate internal fixation through the lateral approach has gradually become a classic treatment for distal femoral fractures. Internal fixation method. Although surgical treatment has achieved good results, postoperative nonunion and internal fixation fractures have been reported in the literature. For patients with broken internal fixation, when the revision operation is performed again, since the lateral plate is an anatomically locked plate, when the same type of plate is selected again, it is often placed in the same position as the first operation. Since the plate is placed in the same position, the locking nail will also be placed in the same position as the first operation, which will lead to weak fixation and even failure of the second operation.
发明内容Contents of the invention
本发明要解决的技术问题是提供一种股骨远端解剖锁定翻修钢板，可以显著改进翻修手术时钢板固定的牢固程度。The technical problem to be solved by the present invention is to provide a distal femur anatomical locking revision plate, which can significantly improve the firmness of plate fixation during revision surgery.
为解决上述技术问题，本发明采取如下技术方案：股骨远端解剖锁定翻修钢板，包括钢板本体；所述的钢板本体上设置有钉孔；所述的钉孔的直径大于原先固定在股骨远端的解剖锁定板的钉孔的直径；所述钢板本体的远端设置把持段；所述的把持段与所述的钢板本体一体成型；所述把持段设置钉孔。In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: the distal femoral anatomical locking revision plate includes a plate body; the plate body is provided with nail holes; the diameter of the nail holes is larger than that previously fixed on the distal femur The diameter of the nail hole of the anatomical locking plate; the distal end of the steel plate body is provided with a holding section; the holding section is integrally formed with the steel plate body; the holding section is provided with a nail hole.
进一步地，所述的把持段和所述的钢板本体连接形成L型结构。Further, the holding section and the steel plate body are connected to form an L-shaped structure.
进一步地，所述的把持段钉孔采用固定（角度）锁定设计或者万向锁定设计；所述的把持段钉孔直径3.5毫米。Further, the nail hole of the holding section adopts a fixed (angle) locking design or a universal locking design; the diameter of the nail hole of the holding section is 3.5 mm.
进一步地，所述的钢板本体钉孔直径大于4.5毫米（4.5毫米为常规股骨远端解剖锁定钢板钉孔大小），且小于5.5毫米（防止过大后影响钢板强度）。Further, the diameter of the nail hole in the steel plate body is greater than 4.5 mm (4.5 mm is the size of the nail hole in the conventional anatomical locking plate of the distal femur) and less than 5.5 mm (to prevent the strength of the steel plate from being too large).
本发明的有益效果：本发明的钢板在钉孔以及与钉孔配合使用的钉子直径增加后，对于骨组织的把持力显著增加，有效解决常规钢板用于翻修时不能够有效固定的问题。Beneficial effects of the present invention: After the diameter of the nail hole and the nail used in conjunction with the nail hole is increased, the steel plate of the present invention has a significantly increased holding force on bone tissue, effectively solving the problem that conventional steel plates cannot be effectively fixed when used for revision.

具体实施方式Detailed ways
下面将通过具体实施方式对本发明的技术方案进行清楚、完整地描述。The technical solutions of the present invention will be clearly and completely described below through specific embodiments.
本发明的股骨远端解剖锁定翻修钢板，股骨远端解剖锁定翻修钢板，包括钢板本体1；钢板本体上设置有钉孔2；所述的钉孔2的直径大于原先固定在股骨远端的解剖锁定板的钉孔的直径；所述钢板本体1的远端设置把持段3；所述的把持段与所述的钢板本体1一体成型；把持段和所述的钢板本体连接形成L型结构;所述把持段设置钉孔2。钢板本体1上钉孔直径大于4.5mm（4.5毫米为常规股骨远端解剖锁定钢板钉孔大小）,且小于5.5mm，把持段钉孔的直径为3.5mm（防止过大后影响钢板强度）。固定（角度）锁定设计或者万向锁定设计；所述的把持段钉孔直径3.5毫米。The distal femur anatomical locking revision plate of the present invention comprises a plate body 1; a nail hole 2 is arranged on the plate body; the diameter of the nail hole 2 is larger than the anatomical locking plate originally fixed on the distal femur. The diameter of the nail hole of the locking plate; the distal end of the steel plate body 1 is provided with a holding section 3; the holding section is integrally formed with the steel plate body 1; the holding section and the steel plate body are connected to form an L-shaped structure; Nail holes 2 are set on the holding section. The diameter of the nail hole on the plate body 1 is greater than 4.5mm (4.5mm is the size of the nail hole in the conventional distal femur anatomical locking plate), and less than 5.5mm, and the diameter of the nail hole in the gripping segment is 3.5mm (to prevent the strength of the plate from being too large). Fixed (angle) locking design or universal locking design; the diameter of the nail hole in the holding section is 3.5mm.
实施例2Example 2
患者股骨远端骨折术后1年余，骨不连，钢板断裂。如果采用相同类型钢板翻修时，由于钢板是解剖钢板，放置位置固定，钉孔固定，因此固定不牢。如果采用本发明的干板，钉孔和钉子直径增加，可以有效固定。同时把持段的设置增加了钢板本体远端（钢板本体下端）的面积，进一步增加把持力。More than 1 year after the operation for the distal femur fracture, the patient suffered from nonunion and fracture of the steel plate. If the same type of steel plate is used for revision, because the steel plate is an anatomical steel plate, the placement position is fixed and the nail holes are fixed, so the fixation is not firm. If the dry plate of the present invention is adopted, the diameter of the nail holes and nails increases, which can be effectively fixed. At the same time, the setting of the holding section increases the area of the far end of the steel plate body (the lower end of the steel plate body), further increasing the holding force.
上面所述的实施例仅仅是本发明的优选实施方式进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计构思的前提下，本领域中普通工程技术人员对本发明的技术方案作出的各种变型和改进均应落入本发明的保护范围，本发明的请求保护的技术内容，已经全部记载在技术要求书中。The embodiment described above is only a description of the preferred implementation of the present invention, and is not intended to limit the concept and scope of the present invention. Various modifications and improvements made should fall within the scope of protection of the present invention, and the technical content claimed for protection in the present invention has been fully recorded in the technical requirements.
