Abstract

The existing backbone fracture reconstruction installment has many disadvantages such as the limitation of the place is big which needs to rectify, binding the patient's joint by the T shape nylon tack-dry belt makes the bar of the obstruction mechanism be limited by the jack and the use is inconvenient, the connection of the support mechanism and the hauling mechanism is only a spot, hauling mechanism's end is easy to rock, thus increasing patient's insufficiencies and so on. The utility model provides a backbone fracture reconstruction installment, two body fixing mechanisms are separately arranged on the hauling wire pole 5 with right and left screws, stably and firmly fixes patient's wound body on the reconstruction installment by the clamping bracket 6 of the body fixed mechanism. The installment tows both sides of the wound body evenly and overcomes the organism resisting force effectively, causes both sides of the doctor-patient to feel no pain and tiredness and enhances the reduction effect.

Description

The shaft fracture reposition device

Technical field the utility model relates to a kind of shaft fracture reposition device, especially AT shaft fracture is not had the used shaft fracture reposition device of wound ground reduction operation.

Background technology is present, in most of hospitals, mostly prolongs reduction by hand for the no wound reduction of AT shaft fracture, and the pain and the effect of the tired pain that doctor and patient is tired are bad.For reducing doctors and patients' inconvenience and painful, people have proposed the reduction apparatus of several fracture.As application number is 89221605.0, and the Chinese patent application of by name " portable fracture of upper limb reset device " is an example wherein.It is made up of the solid mechanism of supporting mechanism, haulage gear and retaining, wherein haulage gear is the dextral inside and outside composite screw screw mandrel in a left side, external screw rod is installed in the female thread of supporting mechanism, the tail end of inner screw bends up structure, be used for patient's fracture distal joint being tied to make drawn by haulage gear with the sticking fixing band of T shape nylon, in operation, the solid mechanism's (pin) of the shelves that are installed in and install on the same base plate of supporting mechanism being saved in patient's fracture near-end pass fixes.But this structure exists many weak points significantly: at first, but the limitation at the position of reduction is bigger, only can be used for upper limb; Secondly, use inconvenience, glue fixing band colligation patient joint with T shape nylon, and the lever of the solid mechanism of retaining is subjected to the solid effect of the made retaining to the patient joint of jack restricted; Once more, the connection of supporting mechanism and haulage gear has only a point, and the tail end of haulage gear rocks easily, thereby increases patient's misery.

Summary of the invention is at this defective, and the technical problems to be solved in the utility model will make the spendable expanded range of shaft fracture reposition device exactly; Use more convenient; More stable.

The shaft fracture reposition device that this utility model provides, form by base, supporting mechanism, haulage gear, limbs fixed mechanism, wherein said supporting mechanism is mounted on the base two bracing frames 10 that an axis hole is arranged on it, and the centrage of the axis hole on described two bracing frames is on the same line; Haulage gear is one and respectively is shaped on the traction screw mandrel 5 of left and right sides spiral with axle mid point branch both sides, and each is installed in the two ends of traction screw mandrel respectively in the axis hole of two bracing frames with the end axle, and traction screw mandrel two end axles is passed on the outer end of bracing frame a handwheel 12 respectively is installed; Also each forms with adjustable shelf 8 and clamping support 6 the limbs fixed mechanism by two, wherein adjustable shelf with female thread be installed in the traction screw mandrel on and on the helical screw of the left and right sides each one, adjustable shelf and one is parallel to the slide rail that draws screw mandrel and cooperates, this slide rail stops the limbs fixed mechanism to rotate according to the traction screw mandrel, clamping support is two and is installed in armful plate 16 that adjustable shelf makes progress above, and have at least a slice to embrace plate and the active installation of adjustable shelf, be furnished with between two upper ends that two are embraced plates and can make two to embrace the tight fishbolts 13 of plate holder.

The shaft fracture reposition device that this utility model provides, in the limbs fixed mechanism, clamping support 6 is installed on the adjustable shelf 8 through axial rotating shaft mechanism.Generally adopt this structure on a limbs fixed mechanism, this structure can make clamping support comply with axial rotating shaft and rotate, to reach the purpose of reduction lateral displacement when carrying out the reduction operation.

The shaft fracture reposition device that this utility model provides, there is an X-ray machine 4 to be installed in the haulage gear top through installing rack, also each installs an end plate 9 movingly on two end axles of traction screw mandrel 5, there is connecting rod 3 to connect between the two end plates 9, as U type tube body, two end plates export-oriented bracing frame 10 directions of traction fiber rod end axle connect axle sleeve and with this axle sleeve in bearing 11 is installed in axis hole on the bracing frame.That is to say that traction screw mandrel 5 is installed on the bracing frame 10 through end plate 9.In when work, rotate in the axis hole of traction screw mandrel on can end plate, and end plate can related haulage gear and the limbs fixed mechanism rotate according to the axis hole of bracing frame together.This structure makes the doctor can easily check patient's traumatic condition before, during and after operation, and is rotated according to the traction fiber rod axis together by haulage gear and limbs fixed mechanism, to reach from different perspectives to hindering the purpose that limb is observed.

The shaft fracture reposition device that this utility model provides, base that its supporting mechanism installs and operating-table are one, and the table top of operating-table can be flat with the bottom surface of supporting mechanism, also can be flat with the bottom surface of clamping support.

The using method of the shaft fracture reposition device that this utility model provides: patient's the limb of hindering is placed on embracing in the plate of two clamping supports, make and embrace plate and will hinder limb backbone's two ends and clamp to embrace fishbolt on the plate, rotate handwheel and make adjustable shelf under the effect of left and right sides spiral, shift to two ends and clamping support is affectedly bashful with the key two ends traction of patient's fracture and through the doctor carry out reduction.Reduction is finished and is carried out clamping plate and fix hindering limb after inspection, opens fishbolt subsequently and patient's the limb of hindering is made suitable post surgery treatment.The shaft fracture reposition device that this utility model provides, its construction features can make it be applied to reduction to any limbs shaft fracture of people, it utilizes two limbs fixed mechanisms that are installed in respectively on the helical screw of the left and right sides, with the clamping support on the limbs fixed mechanism, stable and securely the patient hindered that limb is fixed on the reposition device, uniform balance ground draws and hinders the limb two ends and effectively overcome the human body drag, make all senses of no pain and fatigue of when operation doctor and patient, raising reduction effect.
