Description

Fracture fixing device with adjustable tightness

Technical Field

The utility model relates to a medical instrument, in particular to a fracture fixing device with adjustable tightness.

Background

The prior art generally needs to be fixed by adopting a traditional splint or plaster for patients with limb fracture clinically. Because the clamping plate has small plasticity, the clamping plate is easy to shift during movement, and the fixing effect is not ideal; and the plaster fixation needs to be carried out on site according to the fracture part, so that the operation is complicated and the plaster fixation is not suitable for emergency treatment. Chinese patent CN201516100U discloses a fracture fixator, adopts a plurality of ordinary fixed splint when its splint are fixed, binds at the fracture position with the bandage, generally needs two people to go on in coordination, and one alone adjusts the position of fixed splint, and one alone twines the bandage, sometimes even needs many people to cooperate and just can accomplish to bind, and the operation is troublesome, and it is poor to bind the effect, and the operator hardly grasps the elasticity degree of binding.

Because the splint is rigid structure, difficult regulation, along with the progress of treatment, patient fracture's position is detumescence gradually, and is improved, and splint very easily be in not hard up state, splint become flexible and lead to fracture position to take place the aversion easily, need in time fasten again, and fastening operation has increased medical personnel's work load. Chinese patent CN212395166U discloses a tightness-adjustable splint for orthopaedics, which has the advantages of complex structure, complex operation and inconvenient use. There is a need in clinical practice for a fracture fixation device that is simple in construction and that can be conveniently adjusted for tightness.

Disclosure of Invention

The utility model aims to provide a fracture fixing device with adjustable tightness.

The utility model adopts the following technical scheme: the lifting device comprises a plurality of clamping plates, wherein the clamping plates are provided with an upper plate and a lower plate, and the upper plate is assembled on the lower plate through two lifting seats; the lifting seat comprises an adjusting screw rod and a pair of lifting guide clamping heads, the lifting guide clamping heads are arranged on two side edges of the lower plate, and a pair of bayonets matched with the lifting guide clamping heads are arranged at corresponding positions of the upper plate; the adjusting screw is arranged on the plate body of the upper plate through a nut, and the adjusting screw can adjust the distance between the upper plate and the lower plate; the utility model also comprises a pair of U-shaped buckles which are arranged on the upper surface of the upper plate and can be penetrated with bandages.

The principle and the operation method are as follows:

the upper plate and the lower plate of the device are respectively adjusted to be in a mutually attached state through the adjusting screw, at the moment, the lower end of the adjusting screw does not lean against the lower plate, and the lifting guide clamping head is positioned in the bayonet to keep the lower plate and the upper plate in movable fit and not to fall off. A plurality of splints (generally 4 splints) of the device are respectively penetrated into a serial connection state from U-shaped buckles at the upper end and the lower end by two bandages, the splints in the serial connection state are bound around the fracture part by a conventional method, and the primary tightness degree can be moderately maintained at a looser degree. After preliminary binding, the binding can be adjusted to proper tightness through an adjusting screw. In the use process, along with the gradual detumescence and improvement of the fracture part of a patient, the clamping plate is in a natural loosening state, and the clamping plate can be fastened in time through the adjustment of the adjusting screw.

The utility model has the following advantages: 1. the tightness is convenient to adjust. The adjusting screw is arranged on the plate body of the clamping plate, the tightness of binding can be adjusted at any time along with the recovery condition of the affected limb in the use process, the binding adjusting clamping plate is not required to be removed, and the problems that secondary displacement and the like possibly occur in the binding removing process are avoided. 2. The two adjusting screws are respectively arranged at the upper end and the lower end of the splint, the upper end and the lower end of the lower plate can be respectively adjusted, the adjusting range is larger, the accurate positioning force application can be carried out on the fracture part, the blood disorder of limbs can be avoided, and the treatment effect of fracture reduction is ensured.

Drawings

Fig. 1 is a schematic perspective view of an embodiment of the present utility model.

Fig. 2 is a schematic view of the structure of a plurality of splints for wearing a bandage.

In the figure: the clamping plate comprises a clamping plate 1, an upper plate 2, a lower plate 3, a lifting seat 4, an adjusting screw 5, a lifting guide clamping head 6, a bayonet 7, a U-shaped buckle 8 and a bandage 9.
