Forcing fixing belt for lateral rotary knob type skin transplantation operation

Abstract

The invention relates to a forcing fixing belt for a lateral rotary knob type skin transplantation operation. The forcing fixing belt comprises a press plate of which the two ends are connected with a left fixing belt body and a right fixing belt body respectively. The tail ends of the fixing belt bodies are provided with suture holes respectively. A connection button is arranged in the middle of the left fixing belt body. The press plate comprises a plate-shaped body of which the upper surface is provided with a protruding block with a threaded hole in a side. A knob is arranged at the outer end of a threaded pillar in the threaded hole and the other end of the threaded pillar is connected with a sliding block. The end, facing the right fixing belt body, of the plate-shaped body is provided with a bar-shaped through hole in the width direction. The front end of the right fixing belt body penetrates through the through hole to be connected to the sliding block. The left fixing belt body is connected with the left end of the plate-shaped body. The forcing fixing belt for the lateral rotary knob type skin transplantation operation is simple in structure, easy to manufacture and capable of adjusting the tightness of packaged and forced dressing through an adjusting device so as to maintain relatively-fixed pressure on a transplanted skin piece. Meanwhile, according to the clinic needs, the forced dressing can be opened at any time to detect whether the hematoma occurs under the transplanted skin piece or not and find out surviving conditions of the skin piece. The forcing fixing belt for the lateral rotary knob type skin transplantation operation has the obvious clinic use effect.

Description

technical field [0001] The invention relates to a side knob type 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...

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
