Embodiment 1

[0036] Embodiment one is basically as figure 1 , figure 2 , image 3 with Figure 4 As shown, a heel restorer includes a collar 1, a number of airbags 2 arranged along the axial direction of the collar 1 are bonded to the inner wall of the collar 1, and an air supply part is provided on the outer wall of the collar 1 for supplying The air parts include an air pump 3 fixedly connected to the outer wall of the collar 1 by screws. The air pump 3 can adopt the air pump equipped with Yuwell brand anti-decubitus air mattress. The inflation or deflation between the airbags 2 is carried out alternately.

[0037] Such as figure 1 As shown, the lower end of the collar 1 is provided with a sliding part, and the sliding part includes a sliding bar 4 and a sliding block 5, combined with figure 1 with Figure 4 , the number of sliding rods 4 is three and the three sliding rods 4 are all arranged along the axis of the collar 1, such as figure 1 , the upper end of the slider 4 is weld...

Embodiment 2

[0046] The difference between embodiment two and embodiment one is: as Figure 5 As shown, the air pump 3 is arranged on the right side wall of the collar 1, and a support 14 is welded on the left side wall of the collar 1, and the support 14 is threaded with a fixed screw rod 15 arranged parallel to the slide bar 4. , in order to make the fixed screw rod 15 transmit stably, a plurality of support rings 16 are arranged on the side wall of the collar 1 along the axial direction of the collar 1; the bottom end of the fixed screw rod 15 is fixedly connected with a fixed block 17 by screws, and the fixed block 17 is vertically slidably connected to the slide bar 4, and the slide bar 4 plays a guiding role to the fixed block 17; the fixed block 17 is fixedly connected with a steel needle for fixing the patient's calcaneus through thread fit.

[0047] After utilizing the horizontal pushing block 7, the vertical pushing block 10 and the auxiliary pushing block 12 to complete the redu...

Abstract

The invention relates to the technical field of fracture traction restorers, in particular to a heel restorer. The restorer comprises a lantern ring and a plurality of air bags fixedly connected to the inner wall of the lantern ring, the air bags are arranged in the axis direction of the lantern ring, and an air supply piece communicating with the air bags is fixedly connected to the lantern ring;and one end of the lantern ring is slidably connected to a sliding piece in the axial direction of the lantern ring, the sliding piece is connected to a transverse fixing mechanism and a longitudinalfixing mechanism, and the fixing directions of the transverse fixing mechanism and the vertical fixing mechanism are perpendicular to each other. Before calcaneus is restored, the air bags are used for fixing a leg of a patient, then the transverse fixing mechanism and the longitudinal fixing mechanism are used for restoring the calcaneus, and the problem that in the prior art, the calcaneus fracture cannot be restored conveniently, accurately and rapidly is solved.

Description

technical field [0001] The invention relates to the technical field of fracture traction reducer, in particular to a heel reducer. Background technique [0002] Calcaneal fractures are the most common type of tarsal fractures. At present, the surgical options for calcaneal fractures are mainly open reduction and internal fixation and minimally invasive closed reduction and internal fixation. No matter what method is adopted, the width and height of the calcaneus must be restored. In the process of reducing the width of the calcaneus, both sides of the heel must be squeezed to ensure the partial reduction of the fracture. In the prior art, manual operation is generally used. The palms of both palms squeeze the heel, but this operation is very labor-intensive. Therefore, during the reset process, it is often impossible to quickly and accurately reset due to insufficient strength, causing pain to the patient; at the same time, when resetting the width of the calcaneus Finally,...
