An extracorporeal remote blood supply device for free skin flaps used in plastic surgery

Abstract

The present invention provides an external remote blood supply device for plastic free flaps, comprising a venipuncture needle, a first conduit, a precision peristaltic pump, a second conduit, a flap venous anastomosis needle, an arterial puncture needle, a third conduit, a third conduit Through head, fourth catheter, precision syringe pump, replaceable filter cartridge structure, flap arterial anastomosis needle, heating box, circulating copper tube, disassembly and assembly tube, constant temperature water tank, water pump, disassembly and assembly fixed belt structure, auxiliary traction storage plate structure , the auxiliary support plate frame structure, the fifth conduit and the sixth conduit, and the venipuncture needle is inserted into the upper end of the first conduit. The beneficial effects of the present invention are: through the arrangement of the replaceable filter cartridge structure, when the plug-in plate frame is pulled or pushed, different filter screens can be corresponding to the communication pipes, and then during use, they can be replaced accordingly. The filter screen is used, and the blockage of the single filter screen is avoided, which affects the use.

Description

Technical field [0001] The present invention belongs to the technical field of plastic devices, and in particular, the present invention relates to a distant blood supply device applied to the shaping free flap. Background technique [0002] The flap is a tissue flap comprising skin and subcutaneous fat, which provides a blood circulation by a trip, which can cover the wounds of defects, repair deformity or reconstruction organizers by transfer or transplant. In some particular circumstances, the surgery needs to cut off the blood vessels, so that the flaps are completely free, and under the operation of micro-surgery, the moving flap, the venous vessel breakage is consistent with the vascular portion of the zone, which is It is a free skin. When the creation of the vascular damage, occlusion, it will have a situation where the free flap is transplanted, and there is no suitable blood vessel, vascular, vascular, vascular, distressed, for the above situation, there are some surger...
