Description
Technical field
The invention belongs to technical field of surgical instruments, particularly to a kind of smokeless high frequency electric knife.
Background technology
High frequency electric knife is the conventional operating theater instruments of surgical operation, as shown in figure 1, high frequency electric knife of the prior art includes handss
Handle (1), the front end of handle (1) is electrode (2), and handle (1) is had the connecting line (3) for being connected with electric knife main frame.High-frequency electrical
Knife is heated to tissue when being contacted with human body by the most advanced and sophisticated high-frequency high-voltage current producing of active electrode, realizes to when injected organism tissue
Separation and solidification, thus play cutting and hemostasis purpose.High frequency electric knife instead of mechanical operation knife substantially at present, and it is cut
Cut extremely rapid, and haemostatic effect is good, wound side automatic disinfection can be made simultaneously again.But, high frequency electric knife is in use
So that when injected organism tissue is gasified, produce a large amount of gases, patient easily sucks, negative unhealthy.On the other hand, the gas of generation is led
Cause surgical field of view unintelligible, the electrode of high frequency electric knife is often lived by the stick shift of handle or patient again, affects operation technique, or even produces
Accidental injury, electric injury etc..
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of smokeless high frequency electric knife, it can siphon away in time
The gas that when injected organism tissue gasification produces, provides good surgical field of view to doctor.
To achieve these goals, technical scheme is as follows：A kind of smokeless high frequency electric knife, including handle, handle
Front end be electrode, handle had the connecting line for being connected with electric knife main frame, the front end of described electrode is a kink, bends
One through hole is had on portion, electrode is provided with smoking channle, handle is connected with an airway being connected with suction device, smoking channle
One end is located at the through hole of kink, and the other end of smoking channle is connected with suction device by airway, and suction device has switch.
Because the front end of electrode is a kink, it is to avoid the front end of electrode is lived by the stick shift of handle or patient, makes patient
It can directly be seen that the position that electrode is contacted with when injected organism tissue.When operation produces gas, open the switch of suction device, gas
By airway carrying-off after through hole enters smoking channle, thus providing good surgical field of view to doctor.
As improvement, in the form of sheets, electrode has a subsidiary layer to described electrode, and kink is to the wherein side bending of electrode, attached
Belong to the relative opposite side that layer is located at electrode, described through hole connects the space of the above-mentioned both sides of electrode, and described smoking channle is arranged on attached
In layer.
Due to electrode in the form of sheets, the gas of subsidiary layer side is blocked and will not spill over opposite side by the electrode of lamellar, and
It is directly to be siphoned away positioned at attached in the layer smoking channle.The gas of subsidiary layer opposite side is also drawn onto smoking channle by through hole.
Electrode increased the space shared by electrode, motility relative reduction compared with the electrode of column in prior art after arranging kink
, normal when injected organism tissue is likely to be burnt by the side wall of electrode, subsidiary layer be disposed to avoid the contact aside of electrode
To normal when injected organism tissue.
Improve as further, the width of described subsidiary layer is not less than the width of electrode.The program is conducive to keeping off comprehensively
The side of live electrode, prevents normal when injected organism tissue is produced and accidentally injures evil.
As further improving, the switch of described suction device is located on handle.The program is conducive to quickly starting
Or closing suction device.
As further improving, described subsidiary layer is made up of insulant.
As further improving, the leading section of described kink is rectangular.
The advantage of the program is：During the leading section incision when injected organism tissue of kink, in prior art, the electrode of column is not allowed
Easily judge the depth of incision when injected organism tissue, the leading section of kink is rectangular, cut when injected organism tissue with the right angle of rectangle, use rectangle
Other parts i.e. can determine whether cut depth.
In sum, the present invention has the advantages that structure is simple, practical function, can siphon away when injected organism tissue gasification in time and produce
Gas, provide good surgical field of view to doctor, can reduce the accidental injury to patient while being conducive to doctor's health and do harm to.
