Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multifunctional electrocoagulation suction knife. Background Art

[0002] At present, the high-frequency surgical electrocautery in the prior art can effectively stop bleeding while cutting tissues such as skin, fat, and muscle, so it is widely used clinically. The surgical electrocautery on the market at present consists of a handle shell, an electrosection button, an electrocoagulation button, and a circuit board. The circuit board is inside the handle shell, and an electrocautery head socket is provided at the front end, and the electrocautery head socket is relatively short, resulting in the inability to adjust the length of the electrocautery head. Therefore, during the operation, when a long electrocautery head is needed, the short electrocautery head needs to be unplugged and replaced with a long electrocautery head. Moreover, during one operation, due to the need to target different incision depths, the electrocautery head needs to be replaced multiple times, which is time-consuming and inflexible in operation, and may even delay the operation time. Losing the electrocautery head is also a common problem.

[0009] Further, the reset device can transmit a control signal to the motor by pressing the electric button, and the motor can control the telescopic movement of the protruding part through the control signal.

[0010] Further, a connecting piece is further included, and the electrode cutter head and the suction tube are connected to the head end of the housing through the connecting piece.

[0011] Further, an insulating sleeve is further included. The insulating sleeve is arranged between the electrode cutter head and the suction tube and the connecting piece.

[0012] Further, the housing specifically includes an upper housing and a lower housing, and the upper housing and the lower housing are connected by snap fit;

[0013] Further, the electrode tip is specifically a needle-shaped electrode tip.

[0014] A multifunctional electrocoagulation aspirator of the present invention realizes the telescopic movement of the electrode tip through the setting of a reset device. When the electrode tip extends, it can become a needle-shaped electrocautery knife with both aspiration and electrocoagulation cutting functions, and when the electrode tip retracts, it can become an aspirator with both aspiration and electrocoagulation functions. The advantage of the multifunctional electrocoagulation aspirator of the present invention is that the length of the electrode tip can be flexibly adjusted according to the surgical needs, greatly improving the flexibility and efficiency of surgical operations.
