Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The utility model is shown in fig. 1 to 5, including the electrotome pen 1 of upper and lower direction, the downside of electrotome pen 1 is equipped with circular truncated cone-shaped smoking pipe 2, the internal surface of smoking pipe 2 can laminate with the inclined plane of electrotome pen 1 lower extreme, the inside cavity of smoking pipe 2 and its lower extreme have seted up through-hole 3, the right side of smoking pipe 2 upper end is equipped with rectangular shell 4 rather than inside intercommunication, both sides are articulated respectively around rectangular shell 4 upper end have arc 5, two arc 5 openings are relative, two arc 5 free ends are dismantled and are connected, rectangular shell 4 right-hand member is equipped with left and right sides axial and opening right cylinder 6 through the connecting pipe, coaxial smoking cotton 7 is equipped with in the cylinder 6, cylinder 6 right-hand member threaded connection has opening left lid 8.

In order to enable the free ends of the two arc-shaped plates 5 to be detachably connected, the free end of the arc-shaped plate 5 at the front side is provided with a clamping ring 9, and the free end of the arc-shaped plate 5 at the rear side is provided with a clamping block 10 capable of being clamped in the clamping ring 9.

In order to prevent impurities from entering the smoking pipe 2, a filter screen 11 is arranged at the lower end in the smoking pipe 2.

To facilitate connection to the negative pressure system, the right end of the cover 8 is provided with a cannula 12.

For better smoking effect, the through holes 3 are distributed uniformly along the circumferential direction of the smoking pipe 2.

In order to prevent smoking from impressing the operative field, the left end of the smoking tube 2 is not closed.

When the utility model is used, the snap ring 9 is firstly pulled leftwards to separate the clamping block 10 from the snap ring 9, then the pen point of the disposable electrotome pen 1 passes through the smoke absorbing pipe 2 from the top to the bottom, so that the inclined plane at the lower end of the electrotome pen 1 is attached to the inner surface of the smoke absorbing pipe 2, at the moment, the two arc plates 5 are positioned above the button of the electrotome pen 1, so that the two arc plates 5 are attached to the outer edge surface of the electrotome pen 1, and then the clamping block 10 is clamped in the snap ring 9 by force;

the cover 8 is rotated anticlockwise to separate the cover 8 from the cylinder 6, new smoking cotton 7 is put into the cylinder 6, then the cover 8 is rotated clockwise, the cover 8 is fixed on the cylinder 6, the insertion tube 12 is connected with a negative pressure system of a hospital, then the power supply is switched on for the electrotome pen 1, the electrotome pen 1 is started, the tissue to be cut off on the patient body is cut off by the electrotome pen 1, the smoke generated in the cutting process enters the smoking pipe 2 through the through holes 3 and then enters the cylinder 6 through the rectangular shell 4, and then the smoke is absorbed by the smoking cotton 7, and the left end of the smoking pipe 2 is not closed, so that the operation visual field is not influenced;

after the operation is finished, the power supply of the electrotome pen 1 is cut off, the insertion tube 12 is separated from the negative pressure system, the clamping block 10 is separated from the clamping ring 9, then the two arc plates 5 are opened, the disposable electrotome pen 1 is taken out from the smoking pipe 2, the cover 8 is rotated anticlockwise, the cover 8 is separated from the cylinder 6, the disposable smoking cotton 7 is taken out, the cover 8 is fixed on the cylinder 6 again, then the device is stored, the filter screen 11 can effectively prevent external foreign matters from entering the smoking pipe 2 through the through hole 3 in the storage process, and the smoking effect in the follow-up operation is prevented from being influenced.

The utility model provides an electrotome pen 1 is prior art, and here no longer describes in detail its inner structure.
