Abstract
The invention relates to a reset fixing frame for orthopedics, belonging to the technical field of medical apparatus and instruments for clinical bone-knitting. The reset fixing frame for orthopedics is provided with two fixed base plates and six support rods with adjustable effective lengths, wherein both ends of the support rod are respectively articulated on the two fixed base plates; each support rod is composed of a sleeve and a sliding rod inserted in the sleeve; and the sleeve and the sliding rod are respectively arranged on the fixed base plates through spherical hinges. The support rods are extended and adjusted by utilizing the sliding rods, active movement of the support rods is changed into passive movement driven by the base plates, and six actions such as compression prolongation, left-right angulation, fore-and-aft angulation, left-right translation, for-and-aft translation and rotation can be carried out according to the alignment requirement at bone stump, so that the reset fixing frame for orthopedics is accurate for positioning, simple and convenient to operate and wide in range of application.
Description
Technical field
The present invention relates to clinical synthetism technical field of medical instruments, particularly a kind of be used to the orthopedic external fixer that resets of fracturing.
Background technology
In recent years, the development of fixator for orthopedics department tool is very fast, the orthopedic resetting means of multiple fracture occurred clinically.The universal adjustable fracture outer fixer that is for example designed by the inventor, position and the direction in staple hole are adjusted arbitrarily, the strict restriction that makes the distance of holing in the operation and direction no longer be subjected to holder, thereby reduced operation easier, but the translation of this device and rotation must operate respectively, and degree of accuracy is low.Other three-dimensional external fixator, needed translation in the time of can not satisfying the reduction of the fracture simultaneously too such as Yi Lizhanuofu frame, Brazilian Nissl frame etc., rotation etc. are action all.The patent No. is that the Tai Leshi frame that the spatial frame of ZL96193657.6 is namely used has clinically solved the problems referred to above, it can be only by changing the effective length of six roots of sensation strut, just can carry out simultaneously translation and angle adjustment, but its strut is screw connection structure, namely relatively rotate the adjusting effective length by bolt and nut, needing at first the distortion limbs to be carried out X-ray during operation measures, draw every bar adjusting position according to the bone stump motion value by COMPUTER CALCULATION, although degree of accuracy is high, but complex operation, use cost is high, has limited it and has applied.
Summary of the invention
The purpose of this invention is to provide a kind of orthopaedics resetting orthopedic fixed mount that can simultaneously can carry out translation and angle adjustment and aggregate motion thereof according to bone stump para-position needs, not only accurate positioning, and need not by COMPUTER CALCULATION, simple to operation, fixation is reliable, and use cost is low.
For achieving the above object, orthopaedics of the present invention with the technical scheme of the fixed mount that resets is, it has two fixed underpans and 6 two ends and is hinged on respectively support bar on two fixed underpans, and the effective length of every support bar can be regulated, and each support bar and two fixed underpans are angled the connection all.Every support bar is made of the sleeve pipe of outside and the slide bar that is inserted in the sleeve pipe, and an end of sleeve pipe is with external screw thread, by cooperating the end that ball pivot is installed in sleeve pipe with pressure cap with female thread.The another end of sleeve pipe is with the clamping head that slide bar can be blocked, and the clamping head rear portion is threaded connection locking nut is installed.With external screw thread, by cooperating the end that another ball pivot is installed in slide bar with pressure cap with female thread, be connected with respectively double-screw bolt on the above-mentioned ball pivot in the outer end of slide bar, double-screw bolt cooperates respectively with nut ball pivot is installed on two fixed underpans.
Above-mentioned clamping head is with certain taper, and is vertically upper with several breach, can inwardly oppress clamping head when moving behind the rotational lock nut so that slide bar is fixedly clamped.With at least one axial chute, stepping up the head inboard with the fin that cooperates with this chute on the slide bar surface, the two can make sleeve pipe and slide bar can not produce relative rotation in use.The shape of above-mentioned fixed underpan is preferably annular.
The present invention regulates the screw rod rotation of prior art support bar and is improved to the slide bar telescopic adjustment, change the active exercise of support bar into driven by the chassis passive exercise, can compress prolongation according to bone stump para-position needs, left and right sides angulation, the front and back angulation, left and right sides translation, the front and back translation, six actions such as rotation, to behind the good position locking nut spin locking on the every support bar being got final product, need not COMPUTER CALCULATION, accurate positioning, easy and simple to handle, fixation is reliable, the any hospital that can do fracture fixing operation all can use this product, be convenient to the penetration and promotion in China, accelerating bone healing alleviates patient's misery.

The specific embodiment
The accompanying drawing illustrated embodiment, overall structure of the present invention comprise upper and lower two fixed underpans 1,3 and two ends be hinged on respectively 6 support bars 2 on two fixed underpans 1,3, every support bar 2 is made of the sleeve pipe 4 of outside and the slide bar 12 that is inserted in the sleeve pipe 4, thereby its effective length can telescopic adjustment.The end that sleeve pipe 4 and slide bar 12 are pegged graft is with the clamping head 9 that slide bar 12 can be blocked, sleeve pipe 4 ends at clamping head 9 rear portions are with external screw thread, locking nut 11 is housed on it, clamping head 9 is with certain taper, vertically upper with several breach 10, when moving behind the rotational lock nut 11, clamping head 9 can inwardly be oppressed so that slide bar 12 is fixedly clamped in its inboard.The another end of sleeve pipe 4 is also with external screw thread, by cooperating the end that ball pivot 5 is installed in sleeve pipe 4 with pressure cap 7 with female thread, is connected with double-screw bolt 6 on the ball pivot 5, and double-screw bolt 6 is connected on the fixed underpan 1 by nut 8, thereby makes sleeve pipe 4 and fixed underpan 1 hinged.The outer end of slide bar 12 be diameter larger with externally threaded screw rod head 13, screw rod head 13 end bands are fluted, screw rod head 13 ends that ball pivot 14 is installed in by the pressure cap 16 with female thread, be connected with double-screw bolt 15 on the ball pivot 14, double-screw bolt 15 is connected on the fixed underpan 3 by nut 17, thereby makes slide bar 12 and fixed underpan 3 hinged.With at least one axial chute 18, with the fin 19 that cooperates with this chute 18, the two can make sleeve pipe 4 and slide bar 12 can not produce relative rotation in use in clamping head 9 inboards on slide bar 12 surfaces.Two fixed underpans 1,3 are toroidal, and each support bar 2 and fixed underpan be angled the connection all.
