Abstract
A mammary flap extrication device comprises a cutting blade and a clamping part, wherein the cutting blade is installed on a fixing part, the fixing part is connected with the clamping part through a connecting rod arranged at one end of the fixing part, the distance between the clamping part and the fixing part can be adjusted through the connecting rod, and a handle perpendicular to the cutting blade is arranged at one end, provided with the connecting rod, of the fixing part. Due to the fact that the clamping part is arranged and attached to the skin, extricated flaps are positioned in the same plane, and postoperative hydrops is reduced. Compared with an electrotome extrication method, the mammary flap extrication device avoids flat liquefaction and necrosis caused by high temperature of an electrotome, less skin superficial layer blood vessels are injured, and the occurrence rate of postoperative subcutaneous hydrops and flap necrosis is lowered.
Description
Technical field
The present invention relates to medical instruments field, specifically the free device of a kind of mammary gland flap.
Background technology
So-called mammary gland flap is free refer to and cut skin after, with several, tissue forceps is clamped subcutaneous, the tissue forceps spacing is at 2-3cm, bark pocket skin not, mention tissue forceps, make the whole mammary gland be raised on same aspect, then use electric knife or knife blade or tissue shear to insert subcutaneous, peeled off (subcutaneous only stay a small amount of thin layer fat) along fatty shallow-layer, 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, the cutter head direction is as far as possible parallel with the skin of mammary gland direction, avoids transdermal.
Existing mammary gland flap is free is mainly that the 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 in art, the application electric knife is free causes high temperature, liquefaction of fat, necrosis, abovely all can cause that postoperative hydrops is more;
3) in art, flap is free blocked up or excessively thin;
4) postoperative skin flap necrosis: because free skin flap is too thin, flap of blood is for electric knife high temperature, liquefaction of fat, thrombosis, hypohydrops, infection etc. in poor, art.
Summary of the invention
The inhomogeneous series of problems caused of free skin flap existed for solving the free mode of existing mammary gland flap, the invention provides the free device of a kind of mammary gland flap.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of mammary gland flap device that dissociates, comprise cutting blade and clamping part, described cutting blade is arranged on fixed part, fixed part is connected with the connecting rod that clamping part arranges by fixed part one end, and the spacing between clamping part and fixed part is by the connecting rod adjustment, the rear end of clamping part and fixed part is positioned at same vertical, and fixed part arranges on an end of connecting rod and is provided with the handle perpendicular with cutting blade;
Described cutting blade comprises the afterbody of thickness homogeneous and the cutting part of varied in thickness, and the upper surface of afterbody and cutting part forms smooth flat, described afterbody is arranged on fixed part, the arc that the both sides of cutting part are outwardly convex, the front end of cutting part is that projection is the cut end of arc forward, and the thickness of cutting part reduces backward gradually from cut end.
The edge of described clamping part is arc, or between described clamping part bottom surface and end face, is arc-shaped transition.
Described clamping part be shaped as rectangle or bar shaped.
The free end of described connecting rod passes clamping part, and is connected by threaded engagement with clamping part.
Being shaped as of described fixed part is cylindrical;
The front end of described cutting blade lags behind the front end 0.5cm of clamping part.
The cylinder list structure that described clamping part is long 10cm, thick 1cm, wide 2cm, the length of cutting blade is 10cm, width is 1.5cm.
Described cutting blade and clamping part be arranged in parallel or are obliquely installed, and both are while being obliquely installed, and both spacings increase gradually from a side direction opposite side that is provided with connecting rod.
In the present invention, fixed part can adopt the two halves structure, and by tighting a bolt, cutting blade is fixed to clamp between two halves, the length of the cutting blade afterbody that then can clamp by the adjustment fixed part is adjusted the effective cutting length of cutting blade, to be applicable to different patients; Simultaneously, the distance of adjusting between clamping part and cutting blade by connecting rod can be adjusted the subcutaneous fat thickness of reservation.
In the present invention, the relative position of clamping part and cutting blade can be any, that is to say, before clamping part protrudes from cutting blade, also can lag behind cutting blade, also can be mutually concordant, being advisable slightly forward with respect to cutting blade in the position that preferred mode is clamping part, that is to say that the front end of cutting blade lags behind the front position of clamping part.
Using method of the present invention is: after cutting skin, first from an end the mammary gland seam of dissociating, then free device insertion, skin is embedded between clamping part and cutting blade, and skin is stretched at same plane, the pull handle of then taking advantage of a situation, free skin flap fast.
Beneficial effect: the present invention compared with prior art has the following advantages:
1) by clamping part being set and making clamping part be close to skin, make free flap at same plane, reduced postoperative hydrops;
2) with electric knife free phase ratio, avoid liquefaction of fat, necrosis due to electric knife high temperature, skin shallow-layer angiolysis is relatively less, and postoperative hypohydrops, flap necrosis may incidence rate reduce;
3) free speed is accelerated, and reduces operating time.
