Detachable traction device for orthopedics department

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a detachable tractive device for orthopedics.

Background

In the process of orthopedic surgery, the skin tissue of a human body is often required to be pulled open by using a surgical retractor so as to expose the surgical field and facilitate the surgery on internal tissues such as bones and the like. The existing orthopaedics traction device is generally composed of a handle, a pull arm and a hook body, and because ligaments and muscles on the surface of bones are thick, the traction is very strenuous, so that the labor intensity of medical staff is increased, and the working difficulty of the medical staff is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a detachable tractive device for orthopedics, includes the base, sets up the layer board that is used for placing the affected limb above the base, the symmetry sets up the drag hook in the layer board both sides and is used for the differential screw rod subassembly of lateral adjustment drag hook interval, and differential screw rod subassembly sets up in the base of layer board below, and the drag hook setting is in the base top.

Furthermore, the differential screw assembly comprises a differential screw transversely arranged in the base and sliding blocks symmetrically sleeved at two ends of the differential screw, and hand-operated wheels used for driving the screw to rotate are arranged at the end parts of the differential screw.

Furthermore, differential screw rod subassembly still includes the fixing base that sets up under the layer board and the scalable connecting rod that is used for connecting, and the slider passes through scalable connecting rod and is connected with the fixing base.

Furthermore, the drag hook is horizontally arranged above the supporting plate, the end part of the drag hook is provided with a pneumatic rod for vertical adjustment of the drag hook, and the pneumatic rod is vertically arranged on the sliding block.

Further, the upper surface of the base at the two sides of the supporting plate is symmetrically provided with strip-shaped grooves for the left and right transverse movement of the sliding block.

The utility model has the advantages that the adjustment of the space between the hooks is realized through the hand-operated driven differential screw, the slide block can synchronously move inwards or outwards under the rotation of the screw, the traction is stable, and the labor burden is lightened for medical staff; the pneumatic rod drives the draw hook to lift, and the height of the draw hook can be adjusted according to the thickness of the affected limb, so that the applicability is improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of the upper surface of the base of the present invention.

In the figure, 1, a base, 2, a supporting plate, 3, a draw hook, 4, a differential screw, 5, a sliding block, 6, a hand wheel, 7, a fixed seat, 8, a telescopic connecting rod, 9, a pneumatic rod and 10, a strip-shaped groove are arranged.

Detailed Description

Fig. 1 is the utility model discloses a schematic structural diagram, a detachable tractive device for orthopedics, including base 1, set up and be used for placing the layer board 2 of suffering from the limb, the differential screw rod subassembly that the symmetry set up the drag hook 3 in layer board 2 both sides and be used for the lateral adjustment drag hook 3 interval above base 1, differential screw rod subassembly sets up in the base 1 of layer board 2 below, and drag hook 3 sets up in base 1 top.

During the use, will suffer from the limb and steadily place in layer board 2 top, according to suffering from the limb thickness degree, adjust the height of drag hook 3, establish drag hook 3 hook on the both sides wall of affected part, then rotate hand wheel 6 clockwise, drive both sides drag hook 3 and outwards slide, carry out the tractive to the affected part to convenient operation, according to the demand in the art, can be at any time through hand wheel 6 adjustment tractive distance, the tractive is effectual.

The differential screw assembly comprises a differential screw 4 transversely arranged in the base 1 and sliders 5 symmetrically sleeved at two ends of the differential screw 4, and hand-operated wheels 6 used for driving the screw to rotate are arranged at the end parts of the differential screw 4. Differential screw 4 comprises the screw thread that both ends symmetry set up about by, and hand wheel 6 drives differential screw 4 and rotates, clockwise rotation hand wheel 6, and clockwise rotation is followed to differential screw 4, and both sides slider 5 moves to both ends simultaneously, and tractive distance grow, anticlockwise rotation hand wheel 6, and anticlockwise rotation is followed to differential screw 4, and both sides slider 5 moves to the middle part simultaneously, and the tractive distance diminishes.

The differential screw rod component further comprises a fixed seat 7 arranged right below the supporting plate 2 and a telescopic connecting rod 8 used for connecting, and the sliding block 5 is connected with the fixed seat 7 through the telescopic connecting rod 8. Fixing base 7 passes through the bolt fastening and sets up in base 1 bottom, and scalable connecting rod 8 is through the round pin hub connection slider 5 and fixing base 7 at its both ends, and at the slider 5 in-process that slides, the connecting rod is flexible along with slider 5, plays the effect of strengthening support and connection.
