Description
技术领域technical field
本实用新型属于医疗器械技术领域，尤其涉及一种胫骨外置接首板。The utility model belongs to the technical field of medical devices, in particular to an external tibial head plate.
背景技术Background technique
在胫骨开放骨折后，存在皮肤外伤或者严重皮肤肿胀的情况下，进行骨折的复位及固定，需要对软组织进行广泛切开剥离才能手术，剥离骨块上附着的骨膜。广泛的软组织剥离对骨折端的供血造成不良影响，不利于骨折的恢复，甚至导致骨折不愈合。特别是当骨折是开放情况时，在对胫骨伤口清创后，伤口内放置内固定接骨板螺钉，容易引起局部的感染，甚至导致慢性骨髓炎、感染性骨不连，增加治疗难度及治疗时间。在胫骨的开放骨折清创后，缝合软组织伤口，通过适当的固定方式来稳定骨折，有利于骨折的愈合及伤口的愈合，减少伤口感染的发生。传统的方法是采用外固定架来稳定骨折，但是传统的外固定架体积大，舒适度比较差；同时这一固定方式是是弹性固定，稳定性程度相对差，容易导致骨折的延迟愈合及不愈合。After an open fracture of the tibia, in the case of skin trauma or severe skin swelling, the reduction and fixation of the fracture requires extensive incision and stripping of the soft tissue before the operation, and the periosteum attached to the bone block is peeled off. Extensive soft tissue stripping will adversely affect the blood supply of the fracture, which is not conducive to the recovery of the fracture, and even leads to nonunion of the fracture. Especially when the fracture is open, after debridement of the tibial wound, internal fixation plate screws are placed in the wound, which is likely to cause local infection, and even lead to chronic osteomyelitis and infectious nonunion, increasing the difficulty and time of treatment . After the debridement of the open fracture of the tibia, the soft tissue wound is sutured, and the fracture is stabilized by proper fixation, which is conducive to the healing of the fracture and the wound, and reduces the occurrence of wound infection. The traditional method is to use an external fixator to stabilize the fracture, but the traditional external fixator is bulky and relatively poor in comfort; at the same time, this fixation method is elastic and relatively poor in stability, which can easily lead to delayed union and incomplete fracture heal.

所述的安装孔4在胫骨板1上竖直设置有两排。The mounting holes 4 are vertically arranged in two rows on the tibial plate 1 .
所述的安装孔4内安装有锁定螺钉。Locking screws are installed in the mounting holes 4 .
上下两个安装孔4之间的距离为5mm，第一安装头2的宽度为35mm，第二安装头3的宽度为30mm。The distance between the upper and lower mounting holes 4 is 5 mm, the width of the first mounting head 2 is 35 mm, and the width of the second mounting head 3 is 30 mm.

克氏针孔7设置在第二安装头3的近端。The Kirschner wire hole 7 is arranged at the proximal end of the second mounting head 3 .
本实用新型的工作原理：将胫骨外置接骨板安放到胫骨内铡皮外，与皮肤之间有5-10mm的距离，没有接触皮肤。通过接骨板的锁定螺钉孔内经皮拧入锁定螺钉，固定骨折近端。在牵引复位状态下，通过接骨板的锁定螺钉孔内经皮拧入锁定螺钉，固定骨折远端。并且通过X光透视确定骨折的复位情况。骨折部位不需要进行加压固定。接骨板体部通过锁定螺钉孔再经皮拧入锁定螺钉，达到骨折的稳定固定。通过胫骨外置接骨板固定后，骨折达到的稳定程度与加压内固定无差别，而且较传统外固定架体积小，舒适，宜于长期固定骨折。将胫骨板1贴附在断骨处，通过第一安装头2和第二安装头3将胫骨板1的上下端固定，在骨折复位固定的同时可以不用切开局部软组织，减少软组织破坏，保护骨折端血供，利于骨折的愈合。不用切开局部软组织，同时减少局部切口感染的发生，减少创伤后骨髓炎的发生。手术部位远离骨折端损伤，可以早期手术，利于骨折的闭合复位及固定。减少传统外固定支架的固定相对不稳定而导致的骨折不愈合的发生；传统外固定支架体积大，操作复杂，配带时给患者带来极大的不方便，明显影响患者的生活质量，而外置胫骨锁定接骨板体积小，不影响正常的穿裤子，明显提高患者的生活质量的舒适度；为了保证胫骨远端骨折处的骨面的血液循环顺畅，加速骨折处的愈合，所述接骨板头部开设有减压孔。克氏针孔，既能临时固定骨块或接骨板，又能缝合修补周缘软组织、半月板。The working principle of the utility model is as follows: the tibial external bone plate is placed outside the inner skin of the tibia, with a distance of 5-10mm between the skin and the skin, without touching the skin. Locking screws are screwed percutaneously through the locking screw holes of the bone plate to fix the proximal end of the fracture. In the state of traction reduction, the locking screw is percutaneously screwed into the locking screw hole of the bone plate to fix the distal end of the fracture. And the reduction of the fracture was determined by X-ray perspective. The fracture site does not require compression fixation. The body of the bone plate passes through the locking screw hole and then the locking screw is percutaneously screwed in to achieve stable fixation of the fracture. After fixation with external tibial bone plate, the stability of the fracture is no different from that of pressurized internal fixation, and it is smaller and more comfortable than the traditional external fixator, which is suitable for long-term fixation of fractures. The tibial plate 1 is attached to the broken bone, and the upper and lower ends of the tibial plate 1 are fixed by the first installation head 2 and the second installation head 3. During the reduction and fixation of the fracture, there is no need to cut the local soft tissue, which reduces soft tissue damage and protects the bone. The blood supply to the fracture end is conducive to the healing of the fracture. There is no need to cut local soft tissues, and at the same time reduce the occurrence of local incision infection and post-traumatic osteomyelitis. The operation site is far away from the injury of the fracture end, and early operation can be performed, which is beneficial to the closed reduction and fixation of the fracture. Reduce the occurrence of fracture nonunion caused by the relatively unstable fixation of traditional external fixation brackets; traditional external fixation brackets are bulky and complicated to operate, and bring great inconvenience to patients when wearing them, which significantly affects the quality of life of patients. The external tibial locking bone plate is small in size, does not affect the normal wearing of trousers, and significantly improves the comfort of the patient's quality of life; in order to ensure smooth blood circulation on the bone surface of the distal tibia fracture and accelerate the healing of the fracture, the bone plate There are relief holes on the head of the board. The Kirschner wire holes can not only temporarily fix the bone block or bone plate, but also suture and repair the peripheral soft tissue and meniscus.
以上所述仅是对本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制，凡是依据本实用新型的技术实质对以上实施例所做的任何简单修改，等同变化与修饰，均属于本实用新型技术方案的范围内。The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modifications made to the above embodiments according to the technical essence of the present utility model are equivalent to changes and modifications. All belong to the scope of the technical solution of the utility model.
