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...

Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, a skin-fixable breast cancer skin flap peeling device includes a skin fixing plate 1, a thickness adjusting frame 2, a knife holder fixer 3 and a cutting knife frame 4, and one side of the skin fixing plate 1 is provided with a thickness adjusting frame 2, The skin fixing plate 1 and the thickness adjusting frame 2 are connected through the rotating shaft 5 and the fixing nut 6, the relative angle between the skin fixing plate 1 and the thickness adjusting frame 2 is adjustable, and after adjustment, it is fixed by the fixing nut 6, and the thickness adjusting frame 2 is two There is a toothed structure 401 on the inner surface of the side, and the outside of the two sides of the knife rest holder 3 also has a toothed structure 401, and the two toothed structures 401 match each other. The shape of the upper and lower inner surfaces is consistent with the shape of the lower surface 303 of the skin fixing plate.

Embodiment 2

[0031] Such as image 3 As shown, the skin fixation plate 1 has a hollow structure 301, the side of the hollow structure 301 near the lower surface 303 of the skin fixation plate has micropores 302 communicating with the outside world, the side of the hollow structure 301 has a negative pressure joint 305 communicating with the outside world, the skin fixation plate The shape of the lower surface 303 can be flat or curved, and the upper surface of the skin fixing plate is provided with a grip handle 304, and the shape of the upper surface of the skin fixing plate is not particularly limited.

Embodiment 3

[0033] Such as Figure 4 As shown, the inner surface of both sides of the thickness adjustment frame 2 has a toothed structure 401, and the outer surface of both sides of the knife holder holder 3 also has a toothed structure 401. The two toothed structures 401 match each other, and the specific shape of the toothed structure 401 is not limited. It can be a triangle as shown in the figure, or it can be a square or a semicircle, etc. The relative position of the knife holder holder 3 in the thickness adjustment frame 2 can be adjusted.

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 ...
