Abstract

The utility model discloses a multi-function medical traction-frame which is a medical appliance for the orthopedic department and is composed of a U-shaped frame, a spiral type fixture, a pulley block and a sliding type regulating device. A screw rod of the spiral type fixture can be rotated to be fastened to a cross-rod or a flat plate. The sliding type regulating device can be regulated to alter the height and the direction of the pulleys. Overcoming the defects of the present bed-head traction-frame of being used only for the ordinary bed-head traction, unstable fixation, non regulation of the height and the direction of the pulleys, etc., the traction-frame has wide application, stable fixation, easy operation, a broad range of traction and adjustability of the height and the direction. Having the additional functions of safety-height bed-head traction for the pediatric department, flat-cart traction, operating-table traction, etc., the traction-frame is used for various bed-head tractions.

Description

Multi-function tractor

This utility model is a kind of orthopedic medical device.

Be to constitute now by U type framework and assembly pulley with bedside traction shelf.U type framework two upper ends only have double hook to hang on the head of a bed cross bar, no fixture, and the displacement of easily sliding needs to tie up with rope fixing, both insecure, also inconvenient, not attractive in appearance.Framework and assembly pulley are welded as a whole, and assembly pulley can not lifting, can not rotate, and only can be used for common head of a bed traction.The department of pediatrics safety height of bed head of a bed does not have suitable traction frame at present, children's's bone, and the folding patient can not get effective traction.Be not installed at present the traction frame on horizontal sliding car and the operating-table, the patient of fracture of cervical vertebra is in passing on the way and can not get safe and effective continuous traction in the operation process, has increased the danger of the further spinal cord injury of this type of patient, even threat to life.

This utility model is at above-described shortcoming and defect, developed a kind of traction frame that is applicable to the traction of the various head of a bed, the traction of horizontal sliding car and operating-table traction, for society provides that a kind of of many uses, fixation, operation are nimble, traction height and direction scalable, medical multi-function traction frame that locking tweezers is big.

The medical multi-function traction frame of this utility model is realized by following manner: the traction frame of being made up of U type framework, spiral holder, assembly pulley (11) and slidingtype fixture.There is double hook (1) at U type framework two ends, and double hook (1) has group (2) with trailing arm (3) continuation.Spiral holder is made up of first quarter moon card (5) and screw rod (6), first quarter moon card (5) is corresponding with double hook (1), and double hook (1) hangs on the cross bar, and double hook (1) end and group (2) can be positioned on the flat board, on revolve screw rod (6), first quarter moon card (5) rises and plays fixation.Slide bar (12) can be in sleeve pipe (13) longitudinal sliding motion and axial rotation,, assembly pulley fixing with wing screw (14) slides up and down and rotates with slide bar, i.e. scalable traction height and lead are of many uses, operate nimble.

Spiral holder is made up of first quarter moon card (5) and screw rod (6), be fixed on the trailing arm (3) with fixed sleeving (7), relative with double hook (1), on revolve screw rod (6), first quarter moon card (5) rises, cross bar or flat board be clipped between double hook (1) and the first quarter moon card (5) and play fixation, the slidingtype adjusting device is made up of sliding sleeve (13), slide bar (12) and wing screw (14), sliding sleeve (13) is welded on U type framework bar (4) central authorities, with trailing arm (3) certain angle is arranged.Slide bar (12) is longer metallic rod, is installed in the sliding sleeve (13), can slide up and down and axial rotation, and sliding sleeve (13) sidewall has screw, and wing screw (14) is by screw fixed slip bar (12).Assembly pulley (9) for several pulley longitudinal arrangements be fixed in form in the pulley frame assembly pulley (9) and slide bar (12) with vertical pole (11) by two fixedly spiral shell dish (10) be connected.Slide bar (12) slides up and down, and assembly pulley (9) moves up and down, thereby regulates the traction height.Slide bar (12) axial rotation, assembly pulley (9) rotates thereupon, thereby regulates the angle of traction.

The advantage of this utility model in clinical practice:

1, be used as bedside traction shelf, fixation is operated nimble, traction height and direction scalable, locking tweezers is big, traction effect good.

2, be used as department of pediatrics safety height of bed bedside traction shelf.Slide bar (12) is oppositely packed in the sliding sleeve (13), and assembly pulley (9) reversal of the natural order of things is applicable to the traction of the department of pediatrics head of a bed.

3, be installed on the horizontal sliding car, make the fracture of cervical vertebra patient in transporting the way, can obtain effective continuous traction.

4, install on the operating-table, make the fracture of cervical vertebra patient in operation, can obtain effective continuous traction, can prevent because of the movable spinal cord injury that causes of operation technique vertebral body.

Accompanying drawing is an outward appearance overall scheme of the present utility model: 1-double hook among the figure; The 2-group; The 3-trailing arm; The 4-cross bar; 5-first quarter moon card; The 6-screw rod; The 7-fixed sleeving; The 8-nut; The 9-assembly pulley; 10-is the spiral shell dish fixedly; The 11-vertical pole; The 12-slide bar; The 13-sliding sleeve; The 14-wing screw.
