Abstract
The utility model discloses an outer fixing device for the fracture of calcanei. The utility model is characterized in that both ends of a cylinder 3 are respectively provided with leftwards screwed threads and rightwards screwed threads. Both ends of the cylinder respectively match with a leftwards screwed and a rightwards screwed threaded rods 4 and 6 whose ends are provided with lantern rings 2 and 8, and fastening screws 1 and 7 are arranged on the lantern rings 2 and 8 respectively. A small plane with scale 9 is arranged on the leftwards screwed and the rightwards screwed threaded rods 4 and 6 respectively. The utility model has the advantages that the utility model matches with a Kirschner needle to accurately restore, fix and adjust calcanei damaged by fracture out of the calcanei.
Description
This utility model relates to medical apparatus and instruments, particularly a kind of external fixer for the treatment of fracture of calcaneus.
To the treatment of fracture of calcaneus, generally adopt the method for operation, the effect instability in the prior art.Also have and adopt methods such as steel nail, shellfish Lei Shi folder, Elastic bandage be fixing, but have, can not control the angle of corpora calcanei and the shortcomings such as recovery of articular surface effectively the vertical compression of correcting fracture and the involutory deficiency of talocalcaneal joint face.Deficiency at above technology exists has proposed the purpose of this utility model.
The purpose of this utility model is in order to overcome the deficiency there to be technology to exist, to design a kind of fracture of calcaneus external fixer.
The purpose of this utility model realizes according to structure described below, fracture of calcaneus external fixer of the present utility model, it is characterized in that having left-handed and right-handed thread respectively at the two ends of a cylinder 3, the two ends of this cylinder cooperate with the left-handed and right handed screw 4 and 6 that an end has the collar 2 and 8 respectively, and a trip bolt 1 and 7 are respectively arranged on the collar 2 and 8.Use for convenient, on left-handed and right handed screw 4 and 6, a facet with scale 9 is arranged respectively.
The utility model has the advantages that under the fit applications of one group of Kirschner wire can carry out the external fixation treatment to fracture of calcaneus, method is simple and reliable, can avoid postoperative complication.To correct calcaneal tuberosity on move with the effect of turning up of the broadening of corpora calcanei and corpora calcanei better.By adjusting the extension of cylinder 3 gradually, the compression problem after the fracture of calcaneus body is resolved, be particularly suitable for the treatment of the fracture of calcaneus of old.
The following drawings explanation, accompanying drawing is a topology view of the present utility model, the sequence number of each parts in the accompanying drawings is: 1,7, trip bolt, and 2,8, ring set, 3, cylinder, 4,6, the left and right screw rod that revolves, 5 spanner positions, 9, scale.
Below in conjunction with the embodiment in the accompanying drawing, describe structure of the present utility model and use in detail.With reference to the structure in the accompanying drawing, fracture of calcaneus external fixer of the present utility model, two ends at a cylinder 3 have left-handed and right-handed thread respectively, revolve screw thread about the two ends of this cylinder and cooperate with the left-handed and right handed screw 4 and 6 that an end has the collar 2 and 8 respectively, a trip bolt 1 and 7 are respectively arranged on the collar 2 and 8.On left-handed and right handed screw 4 and 6, a facet with scale 9 is arranged respectively.During use, generally be divided into two groups of uses with six fixtures of the present utility model.When fracture of calcaneus being carried out fixed reset when operation, earlier with one piece of Kirschner wire with patient's cuboid and nut bone traverses fixed and the two ends of Kirschner wire are all exposed outside foot and vertical substantially with the longitudinal axis of foot; Another piece Kirschner wire crosses vertical substantially with tibia with the tibia lower end, and on articular surface about two centimetres, also all expose at the two ends of this Kirschner wire; Get one piece of Kirschner wire again and cross following rear in calcaneal tuberosity.The position of three pieces of Kirschner wires is substantially parallel, all puts fracture of calcaneus fixture of the present utility model at the both ends of each Kirschner wire, makes ring set 2 and 8 be enclosed within the end of Kirschner wire, triplet.The end that is each Kirschner wire all is with two collars 2 or 8, forms the triangle of two sealings in patient's foot both sides, and with trip bolt 1 and 7 collar 2 and 8 is fixed in the both ends of Kirschner wire.Like this, when adjust or rotating cylinder 3 on spanner position 5 time, about revolve screw rod 4 and 6 and this device is extended or shortening.According to the classification of fracture and the degree of injury of calcaneus, by adjusting cylinder 3, screw rod 2 and 8 is elongated or shortened, reach make fracture and articular surface reset and involutory.By the scale on screw rod 4 and 69, make the adjustment basically identical of both sides, i.e. the adjustment of this device of same position is extended from the home position or is shortened identical scale (displacement), or as required, extends or shorten different scale (displacement).Need not perform the operation and to carry out simple external fixation, the maximum to the greatest extent displacement that may recover calcaneal tuberosity angle and talocalcaneal joint face.For the fracture of calcaneus of old, can this device be installed after the osteotomy by operation again, and extend the compression of solution calcaneus body gradually, avoided the operation of bone grafting and patient's misery.The profile of cylinder 3 can adopt the version of prism or directly use two connecting rods connect the left and right sides, two ends spin nuts form one with about revolve the cylinder that screw rod cooperates version, to make things convenient for use.
Claims (2)
1, a kind of fracture of calcaneus external fixer, it is characterized in that having left-handed and right-handed thread respectively at the two ends of a cylinder 3, the two ends of this cylinder cooperate with the left-handed and right handed screw 4 and 6 that an end has the collar 2 and 8 respectively, and a trip bolt 1 and 7 are respectively arranged on the collar 2 and 8.
2,, it is characterized in that on the said left-handed and right handed screw 4 and 6 facet with scale 9 being arranged respectively according to the described fracture of calcaneus external fixer of claim 1.
