阅读说明：本技术 治疗跟骨骨折复位使用的撑扩器 (It treats the support that calcaneus fracture diaplasis uses and expands device ) 是由 杨勤翼 孙京艳 张鑫 于 2018-05-22 设计创作，主要内容包括：本发明提供一种治疗跟骨骨折复位使用的撑扩器,两个并列对应一致的套板在中间采用螺栓连接在一起,在两个并列夹板内面的螺栓上装有可调间距的螺母,两个并列的夹板上均分布有数个可穿入钢针的穿孔。治疗骨折时,在钢针插入骨折位置后,可通过旋转螺母调节两个夹板之间的距离,以此可达到较小创伤而达到骨折复位。(The present invention provides a kind of support expansion device treating calcaneus fracture diaplasis and using, two correspond to consistent cage plate side by side and are bolted together in centre, the nut of adjustable spacing is housed on the bolt of two clamping plate inner faces arranged side by side, is distributed with several perforation for penetrating steel needle on two clamping plates arranged side by side.When treatment fracture, after steel needle is inserted into fracture, the distance between two clamping plates can be adjusted by rotating nuts, with this can reach smaller wound and reach the reduction of the fracture.)

1. a kind of support expansion device treating calcaneus fracture diaplasis and using, including steel needle (5), it is characterised in that: two correspond to one side by side The cage plate (1) of cause is linked together in centre using bolt (2), and being equipped on the bolt (2) of two clamping plate (1) inner faces arranged side by side can The nut (3) of spacing is adjusted, is distributed with several perforation (4) for penetrating steel needle (5) on two clamping plates (1) arranged side by side.

Technical field

The present invention relates to a kind of instrument treating fracture of calcaneus and using, specifically a kind of calcaneus fracture diaplasis for the treatment of makes Device is expanded in support.

Background technique

Doctor will do a L shape notch in outside of heel when treating patient's fracture of calcaneus, carry out reattachment surgery Afterwards, then with Interal fixation it being allowed to rehabilitation, this traditional method be easy to cause local infection, cutaneous necrosis since wound is larger, The postoperative complications such as plate exposure, medical profession came into effect small notch Minimally Invasive Surgery in recent years, and this small notch Minimally Invasive Surgery needs The sclerotin that collapses is strutted to be resetted, but existing operation tool can not reach the satisfied reduction of the fracture under small wound, only The methods of fracture site can be dialled using sled, both influence treatment operation and the reduction of the fracture is undesirable.

Summary of the invention

It is above-mentioned it is an object of the invention to solve the problems, such as, a kind of support expansion treating calcaneus fracture diaplasis and using is provided The both ends of fracture can be strutted under small wound and carry out reduction therapy by device.

The present invention includes steel needle, and used technical solution is: two correspond to consistent cage plate side by side and use in centre It is bolted together, the nut of adjustable spacing is housed on the bolt of two clamping plate inner faces arranged side by side, on two clamping plates arranged side by side It is distributed with several perforation for penetrating steel needle.

The present invention has following advantageous effect: device is expanded in the dedicated support thus constituted, when treating fracture of calcaneus, in fracture site Small wound is opened up, insertion steel needle positions the both ends of fracture, adjusts by rotating nuts and struts fracture site, then passes through X Line, which is had an X-rayed, to be resetted, and is allowed to reset operation quickly, simply, reliably, solves small wound treatment calcaneus fracture diaplasis behaviour now Make inconvenient problem, favourable therapeutic is more convenient and reduces patient suffering.

Detailed description of the invention

The invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is schematic structural view of the invention.

Specific embodiment

Shown in Fig. 1: two are corresponded to consistent cage plate 1 side by side and are linked together in centre using bolt 2, are pressed from both sides side by side at two The nut 3 of adjustable spacing is housed on the bolt 2 of 1 inner face of plate, is distributed on two clamping plates 1 arranged side by side and several penetrates steel needle 5 Perforation 4.

Steel needle 5 according to the present invention is the present common Kirschner wire of hospital's fractures.
