Lose.At present, the operation plan for fracture of calcaneus is broadly divided in traditional incision redution-in-fixed and minimally invasive closed reduction solid
Determine two kinds of art.No matter which kind of art formula is taken, it is necessary to width of calcaneus to be recovered and height（Bohler ' s angles）, in correction calcaneus,
Valgus deformity, rebuilds the anatomic form of subtalar joint posterior articular facet.Traditional incision redution-in-fixed is taken to expand on the outside of L-shaped and is cut
Mouthful, although be conducive to the reduction of the fracture, but postoperative infection, skin edge necrosis probability is high.In recent years, as less invasive techniques are in ankle surgery
In develop rapidly, minimally-invasive treatment fracture of calcaneus is increasingly becoming main flow.Which mainly includes percutaneous reduction by leverage internal fixation, limited
Cut and coordinate reduction by traction internal fixation, arthroscope auxiliary reset internal fixation and Nephrolithotomy Percutaneous etc..However, at present
Not yet there are can be used in clinical position closed reduction calcaneus to broaden the operating theater instruments of deformity, patient often will be by free-hand extruding
Rectification and recovery is carried out, but often because strength is not enough difficult to reach satisfied reset effect, this also becomes restriction minimally-invasive treatment calcaneus bone
The principal element of folding.Therefore, develop for calcaneus broaden deformity reduction instrument be extremely to be necessary.

Above-mentioned fracture of calcaneus loaded reset device, the internal diameter of the circular hole are matched with pressure ball, along hole at the aperture of circular hole
Mouth inwall has screw thread, and the periphery for having annulus, annulus at aperture has screw thread to match with aperture circumferential thread, and annulus is spun on circular hole
At aperture, the upper plane of annulus and clamping plate planes align, the diameter of the diameter of bore of annulus less than pressure ball, the upper end of pressure ball is protruded
Above the upper plane of annulus.
Above-mentioned fracture of calcaneus loaded reset device, has pressing plate, the plate face of pressing plate respectively in the relative plate face of the two clamping plates
Area is corresponding with the plate face area of clamping plate, has multiple circular holes relative one by one with the circular hole of clamping plate plate face, pressing plate in pressing plate plate face
Diameter of the Circularhole diameter of plate face less than pressure ball, the upper end of pressure ball are protruded above the upper plane of pressing plate plate face, pressing plate and clamping plate
Plate face is integrated by bolt connection.
The beneficial effects of the utility model are：
This utility model adopts clamp-type structure, and the plate face of two clamping plates is parallel relative, clamping plate be clipped in need to reset with
Bone both sides, two handles of holding with a firm grip, two clamping plates pressure in the middle of calcaneus two are lateral carry out the reset operation of fracture of calcaneus, reach
Correct calcaneus to broaden the purpose of deformity, while by the pushing back and forth along calcaneus major axis, make uneven broaden with bone recovery
Width originally.Pressure ball and spring on two clamping plates can have more preferable suitability to fracture site, with fracture site
Differing heights carry out overall uniform flexible pressurizing, reach more preferable loaded reset effect.
This utility model is the pioneering of calcaneus fracture diaplasis apparatus, uniformly may be used with simple structure, easy to use, pressurization
Lean on, the advantage that reset effect is good, fracture of calcaneus can be carried out in the state of skin, the soft tissue such as muscle closure is kept multiple
Bit manipulation, corrects calcaneus and broadens deformity, it is to avoid the defect of traditional surgical approaches, is carry out Minimally Invasive Surgery to create favourable bar
Part.
