Embodiment 1

[0026] refer to Figure 2-4 : A distraction fixator for interdigital burn rehabilitation, comprising a body 1, a support plate 2 is fixedly connected to the inside of the body 1, a motor 3 is fixedly connected to one side of the support plate 2, and the output end of the motor 3 is provided with a transmission mechanism , the interior of the body 1 is symmetrically provided with a linkage mechanism and a control mechanism. The transmission mechanism includes a limit mechanism, a worm 4, a two-way threaded rod 6 and a worm wheel 7. One side of the worm wheel 7 meshes with the worm 4 for transmission, and the output end of the motor 3 is connected to The worm 4 is fixedly connected.

[0027] In the present invention, the transmission mechanism includes two balance plates 5 that are fixedly connected to the support plate 2. The two balance plates 5 are both provided with installation holes, the two-way threaded rod 6 is movably sleeved inside the two installation holes, and the w...

Embodiment 2

[0031] refer to figure 1 , image 3 , Figure 5 : This embodiment provides a technical solution on the basis of the first embodiment: the limit mechanism includes limit baffles 20 that are fixedly sleeved with both ends of the bidirectional threaded rod 6, two adjacent limit baffles 20 and The adjacent side of the balance plate 5 is fixedly connected to the limit spring 21, and both ends of the two-way threaded rod 6 move through the interior of the two limit springs 21. A moving plate 9 performs the movement limit treatment, and at the same time, the two-way threaded rod 6 continues to maintain the idling treatment, and simultaneously drives the rotation of the two third bevel gears 17 through the two first bevel gears 8 .

[0032] In the present invention, the first moving plate 9 is threadedly sleeved on the bidirectional threaded rod 6 , and the second moving plate 12 is threadedly sleeved on the two reciprocating screw rods 10 . The tops of the first moving plate 9 and ...

Abstract

The invention discloses a distraction fixator for rehabilitation of interphalangeal burns, relates to the field of medical equipment, and aims to solve the problems that skin tissues are adhered together after burns, particularly interphalangeal wounds need to be separated when hands are burnt, wound skin adhesion is avoided, wound recovery is slow, and wound infection is caused. According to the scheme, the device comprises a device body, a supporting plate is fixedly connected to the interior of the device body, a motor is fixedly connected to one side of the supporting plate, a transmission mechanism is arranged at the output end of the motor, and a linkage mechanism and a control mechanism are symmetrically arranged in the device body; according to the device, the two reciprocating lead screws are driven to rotate through rotation of the two-way threaded rod, meanwhile, the two first moving plates and the two second moving plates are driven to synchronously move in the opposite directions, two adjacent fingers are separated, skin adhesion of scalded parts between the fingers is effectively avoided, the recovery effect of a wound is improved, and infection of the wound is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a distraction fixator for interdigital burn rehabilitation. Background technique [0002] Burns include burns caused by flames, hot water, ultraviolet rays, rays, chemicals, electrical burns, etc. We will collectively refer to them as "burns". Wound treatment can be done to recover burns: mainly to treat the wound, remove necrotic tissue, remove blisters, and medical disinfection. Afterwards, do bandage therapy with medication. Bandage therapy: apply a layer of fine gauze to the wound, and add degreased gauze and cotton pads on the outside, so that the wound can be fully drained, protect the wound, and facilitate the use of external medicine. [0003] After burns, the skin tissue will stick together, especially for hand burns, the wound between the fingers needs to be separated. A distraction fixator for the rehabilitation of interdigital burns. SUMMARY OF THE INVENTION [0...
