Abstract

The utility model relates to an adjustable external-expanding fixing rack, belonging to an external fixing tool for reduction in bone surgery. The utility model mainly comprises a parallel main frame capable of adjusting space transversely. A fixing slot board made of shapeable material is fixed on the main frame through a nut, and the expanding angle of the fixing slot board can be adjusted flexibly. The shapeable fixing slot board can be shaped according to the shapes and the sizes of limbs, so that the limbs and the fixing slot board can be matched. Moreover, angles of the limbs rotating inwards or outwards can be controlled. The utility model has the advantages that the range of application is wide; the utility model doesn't influence an x-ray review; when hip joints flex and extend outwards, the utility model ensures that the movement of the hip joints and knee joints can not be influenced; a user can move with the rack; the adjustment is convenient; particularly, the utility model can adjust space, external-expanding angles and angles of rotating inwards and outwards. The utility model also has the advantages of firm fixation, comfortableness, durability, etc. The utility model is particularly suitable to be used for the external fixation of the reduction and the treatment of patients with pedo-congenital dislocation of hip joints, ischemic necrosis of femoral heads, fracture of hips, etc.

Description

Adjustable abduction fixed mount

This utility model relates to a kind of external fixer, particularly adjustable abduction fixed mount.

The utility model of granting patent should possess novelty, creativeness and practicality.Novelty, be meant in the applying date do not have same invention or utility model to publish on the publication in the past at home and abroad, public use is crossed or otherwise for known to the public at home, do not have in the patent application document that same invention or utility model announced after Patent Office proposed to apply for and was documented in the applying date by other people yet.Creativeness is meant with existing technology before the applying date and compares that this invention has outstanding substantive distinguishing features and obvious improvement, and this utility model has substantive distinguishing features and progress.Practicality is meant that this invention or utility model can make or use, and can produces good effect.

Congenital dislocation of hip joint (CDH) is common congenital malformation clinically, and its fixed problem in back that resets is not well solved always.Breast-stroke Gypsum Fibrosum or breast-stroke support are fixed behind many both at home and abroad at present employing manual reductions, and the hip spica cast fixes after the surgical orthopaedic.Adopt plaster fixation that more shortcoming is arranged, during as operating cost, X ray examination image is unclear, be not easy to keep skin health, can not go adjustment after fixing again, and limit the hip joint activity, give the plaster fixation infant for a long time and also be difficult to bear, and traditional frog leg position will influence capital blood circulation, and the serious complication of ischemic necrosis of femoral head might take place.And the breast-stroke support that adopts at present both at home and abroad, as Pavlik harness, Von Rosen support etc., have again fixing uncertain, adjust inconvenient, can not be with defectives such as change of illness state dynamic adjustments, and the contrast price is expensive.

The purpose of this utility model is intended to avoid the deficiency of above-mentioned prior art and utensil and provides a kind of easy and simple to handle, the X ray examination there is not influence, when guaranteeing hip joint flexing abduction, do not influence the hip and knee activity, and can the tape holder activity, regulate easy, particularly can adjust spacing, abduction angle and inside and outside swing angle degree simultaneously, fixing certain adjustable abduction fixed mount.

The purpose of this utility model is achieved in that

A kind of adjustable abduction fixed mount by parallel body frame, fixedly frid and bandage are formed, is characterized in that: staggered up and down by 2 long 20 centimetres, wide 1 centimetre, thick 0.2 centimetre corrosion resistant plate, two twist drill holes are with the fixing side arm as parallel body frame of nut; Staggered up and down by 2 long 15 centimetres, wide 1 centimetre, thick 0.2 centimetre corrosion resistant plate, two twist drill holes are with the fixing after-frame as parallel body frame of nut.Every plate all bores 10 number holes with spacing, between two at a distance of 2 centimetres.To be fixed on the body frame with nut by the fixedly frid that the shaping material is made, the frid liner is with rubber cushion, and each frid is provided with two of adjustable bandages.

Action principle of the present utility model is such: parallel body frame plays a supportive role, but the equal lateral adjustments length and control two holddown groove distances between plates and abduction angle of front and back frame.The shaping fixedly effect of frid is according to infant lower limb form and varies in size mouldingly that making fixedly, frid and limbs better mate.The effect of frid liner rubber cushion is to increase limb skin and holddown groove interleaf friction power, prevents that limbs from sliding, and plays cushioning effect simultaneously, prevents to damage by pressure skin.Bandage plays the pressurization fixation, prevents that support from getting loose.

Below in conjunction with accompanying drawing and example this utility model is further described:

Fig. 1 is the contour structures sketch map of adjustable abduction fixed mount, among the figure: 1. fixing frid 4. rubber cushions 5. bandages of side arm 2. after-frames 3..

Fig. 2 is a block diagram, among the figure: 1. fixing frid 3. rubber cushions 4. bandages of nut 2..

Studies show that in a large number: a mortar is the prerequisite of hip joint normal development with one heart, during use, select suitable abduction angle concentric to guarantee a mortar, and frame length before and after the lateral adjustments in view of the above, obtaining suitable interval, fixing really after, adjust fixedly frid according to infant lower limb form and size, make the two coupling, and adjust the inside and outside swing angle degree of two lower limb as required, suitable back fastening bandage is fixed.

This adjustable abduction fixed mount has the characteristic of existing breast-stroke support, and is better than existing breast-stroke support aspect following five: the first, passive body frame is made up of the front and back frame that is arranged in parallel, and is sturdy and durable, and can flexible spacing and abduction angle; The second, fixedly frid is made by the shaping material, and is really fixing with trouble limb coupling, and can regulate inside and outside swing angle degree easily; Three, fixedly the frid liner with rubber cushion, increase and skin between frictional force, behind the tighten bandage really fixed limb in the inside and outside swing angle degree of needs; Four, can dynamically adjust spacing, abduction angle and inside and outside swing angle degree with change of illness state; Five, low price.

Claims
