Description

Orthopedic splint

technical field

Background technique

A fracture is a complete or partial break in the continuity of the bone structure. When the bone is subjected to great external force (such as: impact, fall from a height, car accident, etc.), it will lead to fractures. After fracture surgery, it is necessary to use orthopaedic splints to fix the fractured parts.

Currently commonly used orthopaedic splints generally include two corresponding splints, which are then tied to the fracture site by a tie to achieve the purpose of assisting the fixation of the fracture site. However, in the process of use, the splint cannot be adjusted according to the shape of the patient's diseased part, the fixation effect is poor, and during the patient's recovery, the fractured part will gradually reduce swelling.

In a further preferred embodiment, the horizontal plate 91 is fixedly connected with the mounting plate 5, and the two are coaxially arranged.

According to a preferred embodiment of the present invention, a suspension mechanism is provided at the lower part of the horizontal plate 91 , and the suspension mechanism includes a rotating shaft 94 , a reel 95 and a suspension rope 96 .

The inventors of the present invention have found that, when an orthopedic splint is used to fix the fractured part of the arm, it is necessary to take a rope separately for hanging, which is complicated and affects the efficiency of fixation. Therefore, in the present invention, the suspension mechanism is preferably installed on the base, so that the suspension rope can be easily taken.

In a further preferred embodiment, the rotating shaft 94 is inserted between the first side plate 92 and the second side plate 93 , and the rotating shaft 94 can rotate relative to the first side plate 92 and the second side plate 93 .

In a further preferred embodiment, fasteners are provided between the first side plate 92 and the rotating shaft 94 and between the second side plate 93 and the rotating shaft 94 to fix the position of the rotating shaft,

The fasteners are thumbscrews.

According to a preferred embodiment of the present invention, there are two reels 95 , which are coaxially arranged on the outer wall of the rotating shaft 94 ;

The suspension rope 96 has two sections, which are respectively wound on two reels.

In a further preferred embodiment, the ends of the two suspension ropes 96 are connected by a buckle 97 .

In the non-use state, the suspension rope is wound on the reel, and the ends are connected by clips. When the fracture of the patient is fixed, loosen the fasteners, pull the buckle connection of the suspension rope to move down, and hang the The rope drives the reel to rotate, which in turn drives the rotating shaft to rotate; when the suspension rope moves down to an appropriate position, tighten the fasteners to fix the position of the rotating shaft, and then hang the suspension rope on the patient's neck to suspend and operate Convenient and fast.

According to a preferred embodiment of the present invention, as shown in FIG. 5 , a shock absorbing component is arranged at the bottom of the base 9 to shock the entire device in a non-suspended state;

The shock absorber assembly has two groups, which are detachably arranged at the bottom of the first side plate 92 and the second side plate 93 .

The inventors have found that, with the gypsum board fixed in the traditional technology, the patient needs to hoist the diseased part (such as the leg) when the patient is in bed, so as to avoid the gypsum board from contacting the bed surface for a long time. In order to expand the scope of application of the orthopaedic splint, in the present invention, a shock absorption component is preferably arranged at the bottom of the base, so that shock absorption can be achieved in a non-suspended state and the flexibility of use is improved.

In a further preferred embodiment, sliding grooves 921 are provided on the inner walls of the lower ends of the first side plate 92 and the second side plate 93,

In the present invention, the shock absorbing assembly is detachably connected to the first side plate and the second side plate through the slider. When the fracture site does not need to be lifted or the site is inconvenient to hoist, the shock absorbing assembly is connected to the first side plate and the second side plate. The lower part of the side plate and the second side plate makes the sliding block fit in the chute to realize shock absorption; when the fractured part needs to be lifted, the shock absorption component can be removed to reduce the overall weight of the device.

The working process of the utility model is as follows: connect the first gypsum layer, the drug layer and the second gypsum layer with the bonding layer in sequence, and fix them together on the inner walls of the first splint and the second splint, and place the fracture site on the second splint. Between the plaster layers, close the first bracket and the second bracket, and then open the air pump to inflate the air bag, so that the fixing pressure of the first splint and the second splint is appropriate. A through hole is used to observe the swelling of the fracture site, and the airbag can be inflated or deflated to adjust the fixation pressure to maintain a better fixation effect.

When the fractured part is the hand, after fixing the fractured part, pull the buckle connection of the suspension rope to move down, the suspension rope drives the reel to rotate, and then drives the rotation shaft to rotate. When it is in position, tighten the fasteners to fix the position of the rotating shaft, and then hang the suspension rope on the patient's neck for suspension.

When the fractured part is the leg, after the fractured part is fixed, the orthopaedic splint can be suspended through the lifting ears, or a shock absorbing component can be installed at the bottom of the base for non-suspension treatment.
