技术领域technical field
本发明涉及到医疗器械领域，具体的说是一种乳腺皮瓣游离装置。The invention relates to the field of medical equipment, in particular to a device for freeing breast flaps.
背景技术Background technique
所谓的乳腺皮瓣游离是指切开皮肤后，用数把组织钳将皮下夹住，组织钳间距在2—3cm，勿夹皮肤，提起组织钳，使整个被提起的乳腺在同一层面上，然后用电刀、或手术刀片、或组织剪插入皮下，沿脂肪浅层进行剥离（皮下仅留少量薄层脂肪），由近到远，步步推进，逐步游离到整个乳腺腺体范围，应用电刀、刀片或组织剪时刀头方向尽量与乳腺皮肤方向平行，避免穿透皮肤。The so-called free breast flap means that after the skin is incised, several tissue forceps are used to clamp the subcutaneous tissue. The distance between the tissue forceps is 2-3cm. Do not clamp the skin. Lift the tissue forceps so that the entire raised breast is on the same level. Then use an electric knife, surgical blade, or tissue scissors to insert into the subcutaneous layer, and peel off the fat along the superficial layer (only a small amount of thin layer of fat is left under the skin), advancing step by step from near to far, and gradually dissociate to the entire range of breast glands. When using electric knife, blade or tissue scissors, the direction of the knife head should be as parallel as possible to the direction of the mammary gland skin to avoid penetrating the skin.
现有的乳腺皮瓣游离主要为电刀皮瓣游离、皮下注射肾上腺素盐水后用手术刀片游离皮瓣和应用组织剪游离皮瓣，上述皮瓣游离方式存在以下问题：Existing breast flap dissociation mainly includes electrocautery skin flap dissociation, subcutaneous injection of adrenaline saline followed by surgical blade dissociation of skin flap and application of tissue scissors.
1）术中出血：以应用刀片、组织剪为明显；1) Bleeding during operation: it is obvious when using blades and tissue scissors;
2）术后皮下积液：应用电刀、刀片或组织剪，不好把握游离一直处于同一平面，以致游离皮瓣高低不平，术中应用电刀游离导致高温、脂肪液化、坏死，以上均可引起术后积液较多；2) Postoperative subcutaneous effusion: use electric knife, blade or tissue scissors, it is difficult to control the dissociation in the same plane all the time, so that the dissociated skin flap is uneven, and the dissociation of the electric knife during the operation will lead to high temperature, fat liquefaction, and necrosis. All of the above can be used Cause more effusion after operation;
3）术中皮瓣游离过厚或过薄；3) The skin flap is too thick or too thin during the operation;
4）术后皮瓣坏死：由于游离皮瓣太薄、皮瓣血供差、术中电刀高温、脂肪液化、血栓形成、皮下积液、感染等。4) Postoperative flap necrosis: due to too thin free flap, poor blood supply of flap, high temperature of electric knife during operation, fat liquefaction, thrombosis, subcutaneous effusion, infection, etc.
