Breast cancer flap dissection apparatus capable of fixing skin

Abstract

The invention discloses a breast cancer flap dissection apparatus capable of fixing skin. The apparatus comprises a skin fixing plate, a thickness adjusting frame, a knife rest fixator and a cutting knife rest, wherein the thickness adjusting frame is arranged at one side of the skin fixing frame; a relative angle between the skin fixing plate and the thickness adjusting frame is adjustable, and after adjusting and fixing, a connecting angle between the skin fixing plate and the thickness adjusting frame is fixed; the knife rest fixator can move up and down in the thickness adjusting frame; and a cutting head mounting hole is formed in the front end of the cutting knife rest. According to the breast cancer flap dissection apparatus provided by the invention, rapid fixation and separation of breast skin can be achieved through negative-pressure suction, so that the uniformity of flap dissection thickness in a breast cancer radical operation can be improved; and various flap dissection modes can be switched in one flap dissection apparatus by replacing cutting heads.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin flap peeling device for breast cancer. Background technique [0002] At present, radical surgery is still the most important treatment method for breast cancer. The commonly used surgical methods include: radical mastectomy and modified radical mastectomy. Regardless of the surgical method, the breast skin and subcutaneous fat layer need to be peeled off first to form a skin flap. . Radical surgery for breast cancer has high requirements for skin flap stripping, and the thickness of the skin flap should be controlled at 3-4mm. Existing breast cancer skin flap peeling methods mainly include: simply using high-frequency electrocautery to peel the skin flap, subcutaneously injecting adrenaline saline and then using a scalpel to peel the skin flap, and using tissue scissors to peel the skin flap. The most obvious problem with the above-mentioned flap stripping methods is that ...

AI Technical Summary

Problems solved by technology

The most obvious problem with the above-mentioned flap stripping methods is that the thickness of the flap stripping is poorly controlled, and the quality of the flap stripping is greatly affected by the operator's personal experience, and the flap is prone to over-thickness, thinness, and uneven thickness.

Skin flaps that are too thin may cause the skin to detach from the underlying arteries and veins, leading to poor blood circulation and flap necrosis, while flaps that are too thick may result in residual cancer and ultimately lead to a significant increase in the early recurrence rate of breast cancer

[0003] In order to solve the problem of too thick, too thin or uneven thickness of breast cancer surgery skin flaps, some people have designed more reasonable skin flap stripping blades. This design can improve the quality of skin flaps in breast cancer surgery to a certain extent, but the skin flap knife cannot control the shape of the breast skin, so it still cannot fundamentally control the distance and angle between the skin flap knife and the breast skin, so it is still easy Skin flaps that are too thick, too thin, and uneven in thickness
