Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of smoking pipe connecting structure and with the structure
Electric knife.
Background technology
Electric knife is a kind of common surgical knife tool, because when surgical cut is carried out, can produce substantial amounts of smog, is hidden
The sight of doctor is kept off, what influence was performed the operation is normally carried out, so present most of electric knifes all carry fume absorbent function, by true
To perform the operation smog etc. for producing of suction adsorption device is suctioned out and gone, it is ensured that operation normal and be smoothed out, and for example number of patent application is
CN 200920053974.0, the applying date：2009-04-03 Chinese utility model patent discloses a kind of smoking electrotome pen,
Its structure includes body housing, electrode knife head and a Smoking pipe, and a body housing is provided with control button, is provided with circuit structure, inhales
Smoke pipe and a body enclosure interior formation smoking passage, its structure improved is to be additionally provided with swivel head, electrode knife head and Smoking pipe
It is removably mounted on swivel head, swivel head drives electrode knife head and Smoking pipe to be rotatably installed in a body housing forward end, swivel head
The electric connection structure that rear end is electrically connected provided with electrode knife head in holding rotation process with circuit structure.
But, actual production and sales and in use, more complicated operation need be frequently not an electrode just
It is can completing, it is necessary to change electrode, and in such operation, many hospitals and doctor, often not very willing use band
There is the existing electric knife with Smoking pipe so that the application of electric knife is restricted.
The content of the invention
It is an object of the invention to provide there is provided a kind of smoking pipe connecting structure and electricity in view of the deficiencies of the prior art
Knife, its is simple in construction, easy to make, and the replacing of Smoking pipe and length adjustment are convenient, expand the application of electric knife, improve
The efficiency of operation.
In order to solve the above-mentioned technical problem, technical scheme is as follows：Smoking pipe connecting structure, including it is plugged on electricity
Smoking pipe in knife housing handle, the locking annular groove being located on the Smoking pipe outer circumference surface, it is arranged in the locking annular groove
