Description

humerus surgical neck shoulder splint

technical field

The utility model relates to a medical device, in particular to a humeral surgical neck shoulder sealing splint which is not easy to slide and fall off, has firm fixation and good elasticity.

Background technique

After the fracture is reset, redisplacement will occur. When the bone is broken and displaced, the shape of the broken bone tends to be displaced in the direction of displacement. The periosteum on the displaced side is torn, and the soft tissue on the displacement path is damaged. A series of unstable factors have been formed. The bone after reset has a tendency to redisplace along the original displacement path through these weak links. The weight and muscle pull of the distal limb on the injured side promotes redisplacement. Small splint is one of the achievements of external fixation of traditional Chinese and Western medicine in the treatment of fractures, and small splint fixation technology is a more commonly used method in fracture external fixation technology. Modern research shows that the principle of small splint fixation to treat fractures is to combine the fixation force of small splints and paper pressure pads with the restraint force of belts to achieve the purpose of resetting and braking the fracture end and restoring the internal dynamic balance of the limbs. After the splint is fixed, through the combined effect of the cable tie, splint, and pressure pad, it can control the redisplacement activities such as angulation, rotation, and separation of the fracture end, while retaining the activities of opposing compression to facilitate fracture healing.

The surgical neck of the humerus is located 2 to 3 cm below the anatomical neck. It is the junction of the cancellous bone of the humeral head and the cortical bone of the humeral shaft, and is prone to fracture. And utilize splint to treat fracture at this position, adopt four splints to bandage usually, four splints are divided into front, rear, inside and outside four, after four splints are put, fix by bandage. However, in actual use, due to consideration of the patient's blood circulation and patient comfort, the bandage is usually not very fastened, resulting in the phenomenon that the front, rear and outer splints are prone to leaning towards each other, and Due to the lack of centripetal force constraints, the three splints open, causing the splints to slide and loosen up and down, and lose the fixing effect, so that the reduced fracture is displaced again, which affects the rehabilitation of patients with humeral surgical neck fractures.

Contents of the invention

What the utility model aims to solve is the problem that in the treatment process of the existing surgical neck fracture of the humerus, due to the consideration of the patient's limb sensation, the bandage will not be very fastened, so that the splint is easy to slide and loses the fixing effect. Stable and elastic humerus surgical neck splint.

The shoulder seal splint for humerus surgical neck of the utility model includes four splints, front, back, inside and outside, and is characterized in that an airbag is fixed on the inner wall of the four splints, and an air nozzle is arranged on each airbag, through which the air The mouth inflates the air bag.

Fix the four splints on the front, back, inside, and outside of the patient's humerus surgical neck fracture, and make the airbag on the inner wall of each splint close to the patient's body, and then use the air nozzle to inflate the airbag after tightening it with a bandage , after the patient feels pressure within the tolerable range, stop inflating and close the air nozzle. At this time, the immobilization effect is effectively improved by the air pressure, which is beneficial to the recovery of the patient.

The air nozzles are arranged on the top of the airbags, and the four air nozzles are all connected to an air intake pipe, through which the four airbags are inflated at the same time, so as to avoid unbalanced inflation and cause unstable splint fixation or discomfort of the patient.

The air intake pipe is provided with a one-way air intake valve to avoid air leakage in the air bag.

The upper parts of the front, rear and outer three splints are all bent inward, which is beneficial to reduce the possibility of the splints opening after being fixed with bandages.

The humerus surgical neck shoulder seal splint of the utility model has scientific design, reasonable structure and convenient use. An airbag is fixed on the inner wall of the four splints. After the splint is fixed, the airbag is inflated to increase the fixity of the splint and avoid Sliding, falling off, and setting the air nozzle on the top of the airbag at the same time, and connecting the four air nozzles with the air inlet pipe. After fixing, the air inlet pipe can be used to increase the centripetal force of the splint, which effectively prevents the splint from opening and is more conducive to the rehabilitation of patients.

detailed description

Embodiment 1: A kind of lateral condyle neck splint of humerus, including front, back, inside and outside four splints 1, all are fixed with an air bag 2 on the inner wall of four splints 1, and each air bag 2 is all provided with an air nozzle 3 , inflate the airbag 2 through the air nozzle 3 . The air nozzle 3 is arranged on the top of the airbag 2, and the four air nozzles 3 are all connected to an air intake pipe 4, and the four airbags 2 are inflated simultaneously through the air intake pipe 4, so as to avoid unbalanced inflation and cause the splint 1 to be unstable or uncomfortable for the patient. The air intake pipe 4 is provided with a one-way air intake valve 5 to avoid air leakage in the air bag 2 . The upper parts of the front, rear and outer three splints 1 all bend inward, which not only reduces the length of the intake pipe 4, but also can be matched with the intake pipe 4 to increase the centripetal force of the splint 1, effectively preventing the splint 1 from opening.

Fix the four splints 1 on the front, back, inside and outside of the patient's lateral condyle neck fracture respectively, and make the air bag 2 on the inner wall of each splint 1 close to the patient's body. The trachea 4 and the air nozzle 3 inflate the air bag 2. After the patient feels the pressure within the tolerable range, the inflation is stopped and the air nozzle 3 is closed. At this time, the fixation effect is effectively improved by the air pressure, which is beneficial to the patient's recovery.
