Rotary compression fixing band for skin grafting operation

Abstract

Disclosed is a rotary compression fixing band for skin grafting operation. The rotary compression fixing band comprises a pressing plate with two ends respectively connected with a left fixing band and a right fixing band. Stitch holes are respectively formed at tail ends of the left fixing band and the right fixing band, and a fastener is arranged in the middle of the left fixing band. The pressing plate comprises a plate body and a screwdriver; a protrusion with a lateral thread hole is arranged on the upper surface of the plate body, a bolt penetrates the thread hole, a nut is arranged at the left end of the bolt, a slider is connected to the right end of the bolt, and a slotted through hole is formed at the end, facing the right fixing band, of the plate body along the width. The front end of the right fixing band penetrates the through hole to be connected to the slider, and the left fixing band is connected to the left end of the plate body. The screwdriver is matched with the nut. The rotary compression fixing band is simple in structure and easy to manufacture. Tightness of packed compression dressings can be regulated by a regulator so as to keep a relatively fixed pressure to skin graft. With the rotary compression fixing band, the compression dressings can be opened at any time according to clinical needs, so that doctors can check whether hematoma form under skin graft or not and check skin graft surviving conditions. Accordingly, the rotary compression fixing band has remarkable clinical service effect.

Description

technical field [0001] The invention relates to a rotary pressure fixation belt for skin transplantation, which belongs to the technical field of auxiliary medical devices in skin transplantation. Background technique [0002] Skin grafting, also known as skin grafting, is a method of using autologous or allogeneic skin grafts to skin defect areas to heal wounds; or to reconstruct body surface organs due to plastic surgery. When the wound surface in the skin defect area is fresh, a large free skin graft is often used to cover it, and the surrounding edges are sutured and fixed with silk thread. The specific method is as follows: cover the wound with the skin graft under appropriate tension, and suture the edge of the skin graft and the wound margin. In view of the thinness of the skin graft, it is not suitable to suture too much, so as to avoid tearing of the skin graft. Before bandaging, flush the blood under the skin graft with normal saline. Cover the skin graft in the ...

Problems solved by technology

[0003] However, the existing method needs to wait 7-9 days to remove the packed and pressurized dressing and observe the healing of the skin graft, which is not conducive to the observation and treatment of complications such as early hematoma, and the pressure cannot be adjusted after the suture is knotted
