Description
Technical field
The present invention relates to a kind of loaded reset device treating fracture of calcaneus, belong to orthopedic medical device technical field.
Background technology
Fracture of calcaneus is modal fracture of tarsus.During how because of high falling or traffic accident, heel portion suffers caused by external force collision.Wherein intra-articular fracture accounts for the 60%-75% of fracture of calcaneus, may result in foot long pain even afunction if dealing with improperly.At present, the operation plan for fracture of calcaneus is broadly divided into traditional incision redution-in-fixed and Wicresoft's closed reduction internal fixation two kinds.No matter take which kind of art formula, it is necessary to width of calcaneus to be recovered and height (Bohler ' s angle), correct the inside and outside talipes varus of calcaneus, rebuild the anatomic form of subtalar joint posterior articular facet.Traditional incision redution-in-fixed takes to expand outside L-shaped otch, although be conducive to the reduction of the fracture, but postoperative infection, skin edge necrosis probability are high.In recent years, along with less invasive techniques developing rapidly in ankle surgery, minimally-invasive treatment fracture of calcaneus is increasingly becoming main flow.It mainly includes that percutaneous reduction by leverage internal fixation, Limited exposure coordinate reduction by traction internal fixation, arthroscope auxiliary reset internal fixation and Nephrolithotomy Percutaneous etc..But, can be used for not yet occurs at present closed reduction calcaneus in clinical position broaden the operating theater instruments of deformity, patient often to carry out rectification and recovery by free-hand extruding, but often be difficult to reach satisfied reset effect not because of strength, and this also becomes the principal element of restriction minimally-invasive treatment fracture of calcaneus.Therefore, develop for calcaneus broaden deformity reduction instrument be extremely to be necessary.
Summary of the invention
The technical problem to be solved is to provide a kind of fracture of calcaneus loaded reset device, this loaded reset device carries out the operation that resets when keeping the soft tissue such as skin, muscle intact to fracture of calcaneus, correct calcaneus to broaden deformity, to avoid the defect of traditional surgical approaches, create more advantage for carrying out Minimally Invasive Surgery.
The technical scheme solving above-mentioned technical problem is:
A kind of fracture of calcaneus loaded reset device, it includes clamping plate, handle, rotating shaft, pressure ball, spring, two clamping plates is rectangle, and two clamping plates is connected with two handles respectively, and two handles intersect in junction, infall is connected by rotating shaft and forms clamp-type structure, the plate face of the two clamping plates of rotating shaft side is parallel relatively, and two handles of rotating shaft opposite side are relative, have multiple circular hole uniform on the opposite plate face of two clamping plates respectively, being embedded with pressure ball in circular hole, there is spring the lower end of pressure ball.
Above-mentioned fracture of calcaneus loaded reset device, the internal diameter of described circular hole matches with pressure ball, screw thread is had along aperture inwall at the aperture of circular hole, annulus is had at aperture, the periphery of annulus has screw thread to match with aperture circumferential thread, and annulus is spun at the aperture of circular hole, the upper plane of annulus and clamping plate planes align, the diameter of bore of annulus protrudes above the upper plane of annulus less than the diameter of pressure ball, the upper end of pressure ball.
Above-mentioned fracture of calcaneus loaded reset device, pressing plate is had respectively on the plate face that described two clamping plates is relative, the plate face area of pressing plate is corresponding with the plate face area of clamping plate, there is multiple circular hole the most relative with the circular hole in cleat plate face on pressing plate plate face, the Circularhole diameter in pressing plate plate face is less than the diameter of pressure ball, the upper end of pressure ball is protruded above the upper plane in pressing plate plate face, and pressing plate is connected as one by bolt with cleat plate face.
The invention has the beneficial effects as follows:
The present invention uses clamp-type structure, the plate face of two clamping plates is parallel relatively, clamping plate are clipped in the calcaneus both sides needing to reset, hold with a firm grip two handles, two clamping plates is pressure in the middle of calcaneus two is lateral, carries out the reset operation of fracture of calcaneus, reaches to correct calcaneus and broadens the purpose of deformity, simultaneously by the pushing back and forth along calcaneus major axis, make the width that the recovery of the uneven calcaneus broadened is original.Pressure ball and spring on two clamping plates can have more preferable suitability to fracture site, along with the differing heights of fracture site carries out overall uniform flexible pressurizing, reaches more preferable loaded reset effect.
The present invention is the pioneering of calcaneus fracture diaplasis apparatus, there is simple in construction, easy to use, advantage the most reliable, that reset effect is good of pressurizeing, when keeping the soft tissue such as skin, muscle Guan Bi, fracture of calcaneus can be carried out the operation that resets, correct calcaneus to broaden deformity, avoid the defect of traditional surgical approaches, create advantage for carrying out Minimally Invasive Surgery.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional view of a kind of structure of Fig. 1；
Fig. 3 is the sectional view of the another kind of structure of Fig. 1.
In figure, labelling is as follows: clamping plate 1, handle 2, rotating shaft 3, pressure ball 4, spring 5, annulus 6, pressing plate 7.
Detailed description of the invention
The present invention includes clamping plate 1, handle 2, rotating shaft 3, pressure ball 4, spring 5.
Showing in figure, two clamping plates 1 is rectangle, and two clamping plates 1 is connected with two handles 2 respectively, two handles 2 intersect in junction, infall is connected by rotating shaft 3 and forms clamp-type structure, and the plate face of the two clamping plates 1 of rotating shaft 3 side is parallel relatively, and two handles 2 of rotating shaft 3 opposite side are relative.Holding with a firm grip two handles 2, two clamping plates 1 is moved to centre by rotating shaft 3, the calcaneus both sides pressure being placed in the middle of two clamping plates 1 can be carried out the reset operation of fracture of calcaneus, reaches to correct calcaneus and broadens the purpose of deformity.
