Device for draining necrotic tissues after tumor microwave ablation

Abstract

The invention discloses a device for draining necrotic tissues after tumor microwave ablation. The device comprises a containing cylinder, a motor and a plurality of drainage mechanisms, wherein a supporting plate is arranged on the inner wall of the containing cylinder; a bottom plate which is rotatably connected to the containing cylinder is arranged below the containing cylinder; a supporting column is arranged on the supporting plate; a fixed plate is arranged at the top of the supporting column; a magnetic attraction mechanism which is used for adjusting the size of magnetic force is arranged on the periphery of the fixed plate; a plurality of movable mechanisms are uniformly arranged on the outer wall of the containing cylinder; the drainage mechanisms are arranged on the movable mechanisms; a reset mechanism is arranged in each movable mechanism; a magnet is arranged on the reset mechanism; the magnetic attraction mechanism is mutually attracted with the magnet; a plurality of the output end of the motor is provided with a plurality of a plurality of connecting rods; the connecting rods are connected to the inner wall of the containing cylinder; an ablation needle; each drainage mechanism is provided with ablation needles; and the drainage mechanisms are connected to the bottom plate through ropes. The ablation needles of the device can adjust the puncture angle and adapt to tumor ablation work of different sizes and shapes.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to a necrotic tissue drainage device after microwave ablation of tumors. Background technique [0002] When performing tumor ablation surgery, it is necessary to promptly suck out the necrotic tissue from the human body and perform debridement in time to avoid inflammation or even deterioration of the wound. Since the position and shape of the tumor are not fixed, it is not possible to perform ablation surgery. Adjust the corresponding angle according to the shape and position of the tumor, and the heating temperature of the ablation needle is limited to a certain extent. When encountering a larger tumor, the heat will gradually cool down during the transfer process. When it reaches the edge of the tumor At this time, due to the low temperature, the tumor cannot be completely killed, resulting in a poor surgical effect. Contents of the invention [0003] The problem to be solved by ...
