Abstract
A mammary gland flap dissociating device comprises a cutting blade and a clamping portion, wherein the cutting blade is arranged on a fixed portion, the fixed portion is connected with the clamping portion through a connecting rod arranged at one end of the fixed portion, the distance between the clamping portion and fixed portion is adjusted through the connecting rod, and the end, provided with the connecting rod, of the fixed portion is provided with a handle perpendicular to the cutting blade. According to the mammary gland flap dissociating device, the clamping portion is arranged and tightly attached to the skin, and therefore dissociating flaps can be in the same plane, and post-operation dropsy is reduced; compared with electrotome dissociating, flat liquefaction and thanatosis caused by the high temperature of an electrotome are avoided, angiolysis in the shallow layer of the skin is relatively little, and the possible occurrence rate of post-operation dropsy and flap thanatosis can be lowered.
Description
Technical field
This utility model relates to medical instruments field, specifically the free device of a kind of mammary gland flap.
Background technology
Free the referring to of so-called mammary gland flap cut after skin, with several, tissue forceps is clamped subcutaneous, tissue forceps spacing is at 2-3cm, bark pocket skin not, mention tissue forceps, make the whole mammary gland being raised in same aspect, then use electric knife or knife blade or tissue shear to insert subcutaneous, along fatty shallow-layer, peel off (subcutaneous only stay a small amount of thin layer fat), from the near to the remote, advance step by step, progressively dissociate to whole corpus mamma scope, when application electric knife, blade or tissue shear, cutter head direction is as far as possible parallel with skin of mammary gland direction, avoids transdermal.
Existing mammary gland flap is free is mainly that electric knife flap is free, after subcutaneous injection epinephrine saline with knife blade free skin flap and application tissue shear free skin flap, there is following problem in the free mode of above-mentioned flap:
1) intraoperative hemorrhage: take application blade, tissue shear as obvious;
2) postoperative hypohydrops: application electric knife, blade or tissue shear, bad assurance is free always in same plane, so that free skin flap is uneven, and applies that electric knife is free causes high temperature, liquefaction of fat, necrosis in art, all can cause that postoperative hydrops is more above;
3) in art, flap is free blocked up or excessively thin;
