Abstract

The utility model relates to a fixer for resetting a flail chest, which is composed of a fixing frame, a tracing bow and a pair of tracing tongs. The utility model is characterized in that a chute is arranged on the fixing frame and is matched with sliding bars at both heads of the tracing bow; a chute is arranged on the tracing bow; a screw rod of the tracing tongs passes through the chute and is locked and fixed with the tracing bow by nuts which can be adjusted up and down; the lower end of the screw rod of the pair of tracing tongs is provided with a pair of opening tongs which forms four connecting-bar connection with the screw rod of the pair of tracing tongs. The utility model has the advantages of simple structure, stability, reliability and convenient use.

Description

Device for oseosynthesis

Many multistage fractures of rib cause " floating thoracic wall " (that is Durian cangue breast) and serious abnormal breathing, often cause whole body anoxia and intrathoracic internal organs severe complication, so the palpus emergent management is to stablize thoracic wall.The outer doctor of past breast is not because of there being suitable fixture, the thick cotton pad pressure dressing of normal employing is with temporary transient elimination abnormal breathing, again with reset with intramedullary needle fixing and steel wire rib jewel hole or be fastened of operation method, the traction of human towel clamp towel forceps and pulley is also arranged, and that the operative treatment person often only is adapted to body constitution is better or young, the traction of towel clamp towel forceps pulley, loaded down with trivial details and not firm.

The purpose of this utility model is to provide a kind of Durian cangue breast reduction fixture device, and it both can reach and reset, and the fixing purpose of thoracic wall is unlikely operation again or draws with loaded down with trivial details towel clamp towel forceps pulley, and it is simple in structure, and is reliable and stable.

Durian cangue breast reduction fixture device of the present utility model is made up of fixed frame, traction bow and traction tongs, it is characterized in that having on the fixed frame chute, the slide bar at traction bow two cooperates with it, also have chute on the traction bow, the screw rod of traction tongs passes from chute, and be locked with up and down adjustable nut and traction bow, there are individual open mouth tongs the lower end of traction tongs screw rod, and open mouth tongs become four connecting rods to be connected with the traction tongs screw rod.

Holder framework of the present utility model can be made whole, also can make dismountablely, when making with four bars dismountable the time, is convenient to go out to carry.

Fig. 1, structural representation of the present utility model.Wherein, 1 fixed frame, 2 traction bows, 3 traction tongs.

Fig. 2, the structure chart of fixed frame, traction bow among Fig. 1.Wherein, 4 nuts, 5 chutes, 6 chutes, 7 slide bars.

Fig. 3, traction tongs structure chart among Fig. 1.Wherein, 8 screw rods, 9 top nuts, 10 lower nuts, 11 quadric chains, 12 traction tongs.

Be described further below in conjunction with accompanying drawing.

This device mainly is made up of 3 parts, i.e. fixed frame 1, traction bow 2 and traction and fixation pincers 3.Fixed frame 1 is by 4 each length of side 150MM, and wide 20MM, the metal aluminum sheet of thick 4MM form a square or rectangular framework, connects (the time spent is not detachable) with 4 pieces of screws, and width scalable (deciding according to floatability fracture of rib scope); High 50MM "

" the stainless steel traction bow 2 of shape; also be slidingly matched with slide bar 7 and fixed frame 1 and also can lean on its screw thread lock with it, its width and thickness are identical on one side with framework, middle dead slot 6 wide 6MM; the screw rod of traction and fixation pincers 3 is passed from bow, lean on last

lower nut

9,10 to fix; 3-4 clamps 3 to traction and fixation, long 80MM, and the lower end is open mouth tongs 12, the upper end is a screw rod 8, connects with four connecting rods 11 between the two.

Using method.

Preferably can photograph lateral chest film before 1 use, with definite fracture of rib position, radical and hop count, whether the displacement situation has the thoracic cavity organ complication.

2 sterilization skins, local anaesthesia, in floatability rib middle part, costal margin is subcutaneous with the thick needle prick skin up and down, lives unsteady rib middle part with special rib fixed traction pincers clamp, has how many roots are then how many roots of clamp.

3 peaces have been gone into fixed frame, to up and down according to wound district thoracic wall profile two blocks of aluminium sheets are moulded the arcuation that adapts with the thoracic wall profile with hands, layer overlay gauze below each limit of framework, the inside and outside both sides of fixed frame aluminium sheet should place many multiple fracture line places, and promptly the longitudinal fracture line should be pushed down in its both sides.The screw rod of traction and fixation pincers passes the nut of screwing in the middle of traction bow.

4 with the stubborn nut of suitable dynamics, and nut is down tightened more, and rib more up traction rises, so the thoracic wall that subsides resets.Many multistage fracture of rib reset height, level should be consistent, can not the school toward excessively just.

Fixing before and after the special-purpose strap of 5 usefulness (or binder), do not make the fixed mount displacement.

This apparatus structure is simple, and is reliable and stable, easy to use.After using this device and since floating thoracic wall resetted fixing, so thoracic wall regains one's integrity, stable, abnormal breathing Lock-out, pain relief, allow to deeply breathe and effectively cough, the whole body anoxia is improved, thus the generation that reduces or alleviate intrathoracic internal organs (mainly being lung) complication.

This device also can be used for the more tangible non-floatability fracture of rib of displacement.

Claims

1, a kind of Durian cangue breast reduction fixture device, form by fixed frame, traction bow and traction tongs, it is characterized in that having on the fixed frame chute, the slide bar at traction bow two cooperates with it, also have chute on the traction bow, the screw rod of traction tongs passes from chute, and with adjustable nut and traction bow are locked up and down, there are individual open mouth tongs the lower end of traction tongs screw rod, and open mouth tongs become four connecting rods to be connected with the traction tongs screw rod.

2, Durian cangue breast reduction fixture device framework as claimed in claim 1 is characterized in that fixed frame can make wholely, also can make dismountable with four bars and screw.
