Abstract

The invention provides an in-vitro distal blood-supply device for free skin flap for plastic surgery. The device comprises a vein puncture needle, a first catheter, a precision peristaltic pump, a second catheter, a venous skin flap anastomosis needle, an arterial puncture needle, a third catheter, a three-way head, a fourth catheter, a precision syringe pump, a replaceable filter cartridge structure, an arterial skin flap anastomosis needle, a heating box, a circulating copper tube, a disassembly tube, a constant temperature water tank, a water pump, a disassembly and fixing belt structure, an auxiliary traction storage board structure, an auxiliary support plate structure, a fifth tube and a sixth tube, and the vein puncture needle is inserted at the upper end of the first catheter. Thedevice has the beneficial effects that through the arrangement of the replaceable filter cartridge structure, when a plug-in board frame is pulled or pushed, different filter screens can be correspondingly connected with a communication tube, during use, the filter screen can be replaced for use, and the influence of easy obstruction of the single filter screen is avoided.

Description

technical field [0001] The invention belongs to the technical field of plastic surgery equipment, and in particular relates to a remote blood supply device applied to free skin flaps used in plastic surgery. Background technique [0002] A skin flap is a tissue flap containing skin and subcutaneous fat, which provides blood circulation through the pedicle, and can be transferred or transplanted to cover defective wounds, repair deformities or reconstruct tissues and organs. In some specific cases, the operation needs to cut off the vascular pedicle of the flap to make the flap completely free, and under the operation of microsurgical techniques, the arterial and venous ends of the flap should be anastomosed with the blood vessels in the recipient area. It is free flap surgery. However, when the tissue vessels near the wound are damaged or occluded, there will be no suitable blood supply vessels around the wound, and it will be difficult to anastomose the vascular pedicles d...
