Description

Technical Field

[0001] The utility model is applicable to the technical field of medical burn plastic surgery, and particularly relates to a burn plastic surgery skin grafting auxiliary device. Background Art

[0002] At present, in the burn department, some patients will undergo skin grafting surgery due to severe burns. When performing skin grafting on the surface of the patient's limbs, in order to facilitate the surgical operation on the limb to be grafted, corresponding auxiliary support frames are often used to support the patient's limbs and make it easier for medical staff to perform the operation.

[0003] However, when placing the patient's limbs on the support frame for support, the limb lengths of patients of different body shapes are different, which results in the inability to adjust the binding position of the binding ropes on the support frame surface, making it very easy for the support position to hinder the injured limb and affect the subsequent skin grafting quality. Therefore, we propose a burn plastic surgery skin grafting auxiliary device. Utility Model Content

[0011] By adopting the above technical solution, the vertical positions of the supports of the mounting plate and the movable plate can be conveniently adjusted for suitability through the rotational transmission of the lifting sleeve by the rotating screw.

[0013] By adopting the above technical solution, the power source required for adjustment is provided through the driving action of the rotating motor and the servo motor.
