Description

Local skin flap pressurizer

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a local skin flap pressurizer.

Background

After a local skin flap is transplanted by an orthopedics surgeon, a circle of suture is reserved at the suture position of a wound surface and the skin flap, a disinfection bandage with a certain length is cut according to the size of the wound surface, kneaded into a ball and filled on the skin flap, and then the bandage is bundled by the suture for pressurization. Then covering with cotton pad or gauze for bandaging. In the second method, gauze is cut into pieces, and then the pieces of gauze are packed, and the wound surface is pressurized. The third approach is direct compression of the cotton pad.

The existing local skin flap pressurizing method is used for bundling a bandage by utilizing a suture between a skin flap and a wound surface, so that a circle of skin around the skin flap can be lifted, the attachment of the edge of the skin flap and the wound surface is not facilitated, and skin scars are easy to occur after an operation. In addition, the gauze stacking method needs to sew a circle of tight suture around the wound, so as to prolong the operation time; the pressure dressing after the skin flap transplantation is very important, the pressure is moderate, a dead space is left under the skin flap with over-low pressure, and the blood circulation of the wound surface of a receiving area is blocked by over-high pressure, so that the survival of the skin flap is influenced. The existing pressure binding method can not flexibly/freely adjust the pressure. In the existing binding method, gauze is piled for suture packaging, the pressure distribution applied to the wound surface is unclear, local subcutaneous hematocele can be caused, infection is caused, and skin flap transplantation failure is caused. The existing packing method is not suitable for being opened within ten days after operation, and the operation is very inconvenient because of repacking and pressurizing, so that the skin flap recovery condition cannot be observed well.
