Abstract

The utility model discloses a reset fixing frame for the department of orthopaedics, and belongs to the technical field of medical equipment for clinical bone setting. The reset fixing frame is provided with two fixing base plates and six supporting rods, wherein the two ends of each supporting rod are hinged to the two fixing base plates respectively and the effective length of each supporting rod is adjustable. Each supporting rod is composed of a casing pipe and a sliding rod inserted into the casing pipe, wherein the casing pipes and the sliding rods are installed on the fixing base plates through spherical hinges. The supporting rods are retractably adjusted through the sliding rods, the active movement of the supporting rods is changed into the passive movement driven by the base plates, six movements such as compressing lengthening, left-and-right angulation, front-and-back angulation, left-and-right horizontal movement, front-and-back horizontal movement and rotation can be carried out according to bone stump counterpoint demands, the positioning is accurate, operation is easy and convenient, and the application range is wide.

Description

Orthopaedics is with the fixed mount that resets

Technical field

This utility model relates to clinical synthetism technical field of medical instruments, and is particularly a kind of for the orthopedic external fixer that resets of fracture.

Background technology

In recent years, orthopaedics is very fast with the fixed apparatus development, has occurred the orthopedic resetting means of multiple fracture clinically.For example by the universal adjustable fracture external fixator of inventor design, position and the direction in staple hole are adjusted arbitrarily, make distance and the direction of holing in the operation limited by the strictness of holder, thereby reduced operation easier, but the translation of this device and rotation must be operated respectively, and degree of accuracy is low.Other three-dimensional external fixer, 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 translation and angle adjustment simultaneously, 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, though degree of accuracy height, but complex operation, the use cost height has limited it and has applied.

Summary of the invention

The purpose of this utility model provides and a kind ofly can need the orthopaedics resetting orthopedic fixed mount that can carry out translation and angle adjustment and aggregate motion thereof simultaneously according to the bone stump para-position, not only accurate positioning, and need not to pass through COMPUTER CALCULATION, simple to operation, fixation is reliable, and use cost is low.

For achieving the above object, this utility model orthopaedics with the technical scheme of the fixed mount that resets is, it has two fixed underpans and 6 two ends and is hinged on support bar on two fixed underpans respectively, 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 has external screw thread, by cooperating the end that ball pivot is installed in sleeve pipe with the pressure cap that has female thread.The other end of sleeve pipe has the clamping head that slide bar can be blocked, and the clamping head rear portion is equipped with locking nut by being threaded.Outer end at slide bar has external screw thread, by cooperating the end that another ball pivot is installed in slide bar with the pressure cap that has female thread, is connected with double-screw bolt on the above-mentioned ball pivot respectively, and double-screw bolt cooperates respectively with nut ball pivot is installed on two fixed underpans.

Above-mentioned clamping head has certain taper, has several breach on vertically, can inwardly oppress clamping head when moving behind the rotational lock nut so that slide bar is fixedly clamped.Have at least one axial chute on the slide bar surface, have the fin that cooperates with this chute in the clamping head inboard, the two can make sleeve pipe and slide bar can not produce relative rotation in use.The shape on said fixing chassis is preferably annular.

This utility model is regulated 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, about become the angle, front and back become the angle, 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 the fracture fixation 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 utility model comprise upper and lower two fixed underpans 1,3 and two ends be hinged on 6 support bars 2 on two fixed underpans 1,3 respectively, 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.Sleeve pipe 4 has the clamping head 9 that slide bar 12 can be blocked with the end that slide bar 12 is pegged graft, sleeve pipe 4 ends at clamping head 9 rear portions have external screw thread, locking nut 11 is housed on it, clamping head 9 has certain taper, have several breach 10 vertically, 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 end in addition of sleeve pipe 4 also has external screw thread, by cooperating the end that ball pivot 5 is installed in sleeve pipe 4 with the pressure cap 7 that has 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 bigger have an externally threaded screw rod head 13, screw rod head 13 ends have groove, screw rod head 13 ends that ball pivot 14 is installed in by the pressure cap 16 that has 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.Have at least one axial chute 18 on slide bar 12 surfaces, have the fin 19 that cooperates with this chute 18 in clamping head 9 inboards, the two can make sleeve pipe 4 and slide bar 12 can not produce relative rotation in use.Two fixed underpans 1,3 are toroidal, and each support bar 2 and fixed underpan be angled the connection all.
