Embodiment 1

[0020] Refer to attached figure 1 , 2 , 3, 4:

[0021] The gynecological smoking knife system includes an electric knife handle 3, a suction tube 2, and a gynecological electrode 1. One end of the electric knife handle 3 is connected to the smoking machine through a hollow connecting tube 4, and the gynecological electrode 1 is installed on the suction tube 2. Above, the front end of the electric knife handle 3 is detachably connected to the rear end of the suction tube 2 through the guide nozzle 7, and conducts current.

[0022] The guide nozzle 7 is provided with a cross-section longitudinal groove at the front end of the electric knife handle 3, and a longitudinal protrusion cooperating with the longitudinal groove is arranged at the rear end of the suction tube 2.

[0023] Alternatively, the guide nozzle 7 is provided with a cross-sectional longitudinal groove at the rear end of the suction tube 2 , and a longitudinal protrusion matched with the longitudinal groove is pr...

Embodiment 2

[0026] Refer to attached figure 1 , 2 , 5, 6:

[0027] The difference between this embodiment and Embodiment 1 is that the shape of the guide nozzle 7 is different.

[0028] The guide nozzle 7 is provided with a trapezoidal longitudinal groove in cross section at the front end of the electric knife handle 3, and a longitudinal protrusion cooperating with the longitudinal groove is arranged at the rear end of the suction tube 2.

[0029] Alternatively, the guide nozzle 7 is provided with a longitudinal groove with a trapezoidal cross section at the rear end of the suction tube 2 , and a longitudinal protrusion matched with the longitudinal groove is provided at the front end of the electric knife handle 3 .

Abstract

The invention discloses a gynaecologic smoke absorbing knife, which comprises an electrotome handle, a suction tube, and a gynaecologic electrode, wherein one end of the electrotome handle is connected with a smoke absorbing machine through a hollow connection tube; the gynaecologic electrode is arranged on the suction tube; and the front end of the electrotome handle is connected with the rear end of the suction tube through a guide nozzle in a detachable mode and conducts current. The gynaecologic smoke absorbing knife has a simple structure, is convenient to use, and has a good smoke absorbing effect, and cutter bits which are provided with the electrode and the suction tube, and have different lengths and different shapes can be changed.

Description

technical field [0001] The invention relates to an electric knife for gynecological surgery, in particular to an electric knife with smoking function. Background technique [0002] In the prior art, when operating with a scalpel in gynecological surgery, the structure of the surgical site should be narrow, and a large amount of smoke will be generated, which hinders the doctor's field of vision during the operation and causes a series of problems such as long operation time; in order to ensure Due to the clear vision during the operation, the doctor had to use a dilator with suction effect during the operation. However, the distance between the source of smoke generated during the operation and the dilator with suction effect is relatively far, so the suction effect is poor , and its connecting tube is likely to cause surgical involvement, cause surgical obstacles, and affect the surgical process. [0003] In the prior art, the smoking knife can absorb waste such as smoke, ...
