Abstract
The utility model relates to an external fixing frame for fracture resetting in medical treatment. The utility model is composed of a regulating screw, a fixed needle, a rainbow-shaped needle clamp, a connecting needle clamp and a plate needle clamp which are assembled according to practical operation requirement. The middle part of each needle clamp has an adjusting slotted hole in which a rotary needle locking device is arranged, and the needle locking device is provided with a fixed needle. The utility model can be disassembled or assembled according to the required strength of fracture fixation and the requirement of needle threading direction in order to meet the requirements of fracture fixation of the shaft of the femur, the neck of the femur, the intertrochanter of the femur, the tibiofibula, the humerus and the ulnar flexible bone.
Description
This utility model belongs to medical apparatus and instruments, is a kind of reduction of the fracture and multifunctional assembled external fixer of fixed many rainbows of being used for.
At present, existing like product has " one-sided multifunctional external fixation apparatus ", and its structure is a garden cylindricality articulated structure, its principle be by this apparatus to fracture carry out one-sided, monoplane, half pin is fixed.The locking pin of this structure is far away from fracture end, and from the mechanics principle analysis, the major defect of this fixed mount is a poor stability.
It is strong to the objective of the invention is to design a kind of stability, regulates the multifunctional assembled external fixer of many rainbows of fixed position, distance arbitrarily.
Concrete scheme of the present utility model is: with some adjusting screw(rod)s is main bone, is equipped with rainbow type needle clamp, connects pin card, straight needle clamp, according to the clinical practice needs, is combined into the one-sided or bilateral multi-form fixed mount in many planes; The design of rainbow shape pin khaki two ends has slide opening to debug the joint screw rod, and by the nut location, the rainbow type needle clamp middle part has the adjusting slotted eye, regulates dress rotation purl device in the slotted eye, and the nut location is arranged, and adorns locking pin on the purl device; Connect the pin card, it is basic identical with rainbow type needle clamp, and just at one end design has pin card line mutual connection structure; Straight needle clamp, the design of its two ends has bolt head, is loaded on two rainbow type needle clamps or two and connects pin card or rainbow type needle clamp and be connected between the pin card, and use the nut location, the middle part design of straight needle clamp has the adjusting slotted eye, dress rotation purl device, the nut location is arranged, adorn locking pin on the purl device.
Structure of the present utility model can realize the adjusting of any fixed position, distance, excellent stability, and can require to dismantle combination according to the desired intensity of fracture fixation and the direction of threading a needle, scratch the needs of bone fracture fixation to satisfy femoral shaft, neck of femur, intertrochanteric fracture of the femur and tibiofibula, humerus and chi.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a single side type schematic perspective view of the present utility model;
Fig. 2 is a double-flanged end schematic perspective view of the present utility model.
Embodiment 1: referring to Fig. 1, this utility model constitutes main body by two adjusting screw(rod)s 1 and eight setscrew nuts 2 and four rainbow type needle clamps 3, have two at the middle part of each rainbow type needle clamp 3 and regulate slotted eye 4, between last two rainbow type needle clamps 3 straight needle clamp 5 is housed, the bolts at two ends head of straight needle clamp 5 interts locatees in the adjusting slotted eye of rainbow type needle clamp and with nut; Four purl devices 7 that are equipped with are contained on the adjusting slotted eye of straight needle clamp and rainbow type needle clamp with nut by the diagram preparation, and one piece of locking pin 6 is equipped with in each locking on four purl devices 7.
During the practical clinical operation, be as required, at first with adjusting screw(rod) 1, rainbow type needle clamp 3, straight needle clamp 5 location, refill purl device 7 in suitable position, in the purl device, insert locking pin 6, rotation location then, in body, squeeze into locking pin 6, screw purl device 7 locking pin 6 lockings.
Embodiment 2, referring to Fig. 2, this utility model is by five adjusting screw(rod)s 1, three rainbow type needle clamps 3, four connect pin card 8 and seven a kind of typical double-flanged end fixed mounts that purl device 7 is combined into by figure with four locking pins 6, in this, four mutual connection structures that connect pin card 8 are the simplest a kind of mutual connection structures.Every pair connects pin khaki mutual connection end and is fixed with bolt 9 by two one side of something head butt joint backs.
The clinical practice operating principle of this double-flanged end fixed mount and mode are substantially with example 1.
This utility model also can be combined into other forms of fixed mount according to the clinical practice needs.
Claims (1)
