Postoperative drainage device for breast cancer

Abstract

The invention belongs to the technical field of medical drainage devices, and particularly relates to a breast cancer postoperative drainage device which comprises a negative pressure bin and a partition plate arranged in the negative pressure bin. The negative pressure bin is divided into an equipment chamber and a negative pressure chamber by the partition plate; a piston is arranged in the negative pressure chamber, and the negative pressure chamber is divided into a front chamber and a rear chamber through the piston; the front chamber is communicated with a liquid accumulation chamber through a pipeline, and the liquid accumulation chamber is communicated with a drainage tube; a piston rod is connected to the piston, the piston rod penetrates through the partition plate through the rear cavity and extends into the equipment cavity, and a driving device capable of driving the piston rod to move and further driving the piston to move back and forth in the negative pressure cavity is arranged in the equipment cavity. The driving device is arranged to drive the piston to move towards one end close to the equipment cavity, so that negative pressure formed by the hydrops cavity acts on an operation wound surface connected with the drainage tube, and negative pressure drainage force is achieved; and the adjustment of the negative pressure can be realized by adjusting the output power of the driving device.

Description

technical field [0001] The invention belongs to the technical field of medical drainage devices, and in particular relates to a drainage device after breast cancer surgery. Background technique [0002] At present, the surgical methods for breast cancer in my country mainly include the following types, namely, classic radical mastectomy, modified radical mastectomy, extended radical mastectomy, simple mastectomy and partial mastectomy, etc. Generally, except for partial mastectomy, the rest of breast cancer Drainage is required after surgery. The reason is that the surgical wound is large, and at the same time, the lymph nodes in the armpit must be cleaned. Under the skin, therefore, it is necessary to prevent the drainage tube and use continuous negative pressure suction to continuously suck out the accumulated blood and exudate, so that the skin flap can stick to the wound surface, which is conducive to wound healing and prevents necrosis and infection of the skin flap.
