Description
Technical field
The invention belongs to technical field of surgical instruments, particularly the smokeless high frequency electric knife of one.
Background technology
High frequency electric knife is operating conventional operating theater instruments, as shown in Figure 1, high frequency electric knife of the prior art comprises handle (1), the front end of handle (1) is electrode (2), handle (1) has the connecting line (3) for being connected with electric knife main frame.High frequency electric knife is heated tissue when contact with human body by the high-frequency high-voltage current that active electrode tip produces, and realizes the separation of when injected organism tissue and solidifies, thus playing the object of cutting and stopping blooding.Current high frequency electric knife instead of mechanical operation cutter substantially, and its cutting is very rapid, and haemostatic effect is good, can make again wound limit automatic disinfection simultaneously.But high frequency electric knife in use easily makes when injected organism tissue gasify, and produce a large amount of gas, patient easily sucks, negative unhealthy.On the other hand, the gas of generation causes surgical field of view unintelligible, and the electrode of high frequency electric knife is often lived by the stick shift of handle or patient again, affects operation technique, even produces accidental injury, electric injury etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of smokeless high frequency electric knife, it can siphon away the gas that when injected organism tissue gasification produces in time, provides good surgical field of view to doctor.
To achieve these goals, technical scheme of the present invention is as follows: a kind of smokeless high frequency electric knife, comprise handle, the front end of handle is electrode, handle there is the connecting line for being connected with electric knife main frame, the front end of described electrode is a kink, kink there is a through hole, electrode is provided with smoking channle, handle is connected with an airway be communicated with suction device, one end of smoking channle is positioned at the through hole of kink, and the other end of smoking channle is communicated with suction device by airway, and suction device has switch.
Because the front end of electrode is a kink, the front end avoiding electrode is lived by the stick shift of handle or patient, makes patient directly can see the position that electrode contacts with when injected organism tissue.When producing gas when performing the operation, open the switch of suction device, gas is entered by airway carrying-off after smoking channle by through hole, thus provides 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 a wherein lateral buckling of electrode, and subsidiary layer is positioned at the relative opposite side of electrode, and described through hole is communicated with the space of the above-mentioned both sides of electrode, and described smoking channle is arranged in subsidiary layer.
Due to electrode in the form of sheets, the gas of subsidiary layer side is blocked can not overflow to opposite side by the electrode of lamellar, but is directly siphoned away by the smoking channle being positioned at subsidiary layer.The gas of the relative side of subsidiary layer is also drawn onto smoking channle by through hole.Electrode adds the space shared by electrode after arranging kink, motility reduces relatively compared with the electrode of column in prior art, normal when injected organism tissue also may be burnt by the sidewall of electrode, and the setting of subsidiary layer is in order to avoid the contact aside of electrode to normal when injected organism tissue.
As further improvement, the width of described subsidiary layer is not less than the width of electrode.The program is conducive to the side comprehensively blocking electrode, prevents from producing normal when injected organism tissue accidentally injuring evil.
As further improving, the switch of described suction device is positioned on handle.The program is conducive to starting fast or closing suction device.
As further improving, described subsidiary layer is that insulant is made.
As further improving, the leading section of described kink is rectangular.
The advantage of the program is: when when injected organism tissue is cut in the leading section of kink, in prior art, the electrode of column is not easy the degree of depth judging incision when injected organism tissue, the leading section of kink is rectangular, with the right angle incision when injected organism tissue of rectangle, can judge the degree of depth cut by other parts of rectangle.
In sum, the present invention has that structure is simple, the advantage of practical function, can siphon away the gas that when injected organism tissue gasification produces in time, provide good surgical field of view to doctor, can reduce and do harm to the accidental injury of patient while being conducive to doctor's health.
