Intermediate position offers cavity groove on the inside of the ceramic head, and described ceramic head one end is installed with adjustable knife bar and coupled
It connects, physiological saline instillation mouth is offered on the adjustable knife bar, adjustable knife bar one end end cap is set to fixing piece
Interior, described fixing piece one end is equipped with knife handle and connect with it in rotary separated, and the knife handle outer surface is equipped with antiskid thread.
First through hole and the second through-hole are offered in the knife handle as a further improvement of the utility model, attracts punching
It washes pipeline to extend in cavity groove through in first through hole and to one end, instillation pipeline prolongs through in first through hole and to one end
Extend to physiological saline instillation mouth.
The external surface of fixing member is equipped with thread protrusion, the knife handle inside as a further improvement of the utility model,
Thread groove is offered in cavity groove, the thread protrusion is connect with thread groove in rotary separated.
Described knife handle one end is installed with power cable as a further improvement of the utility model, and the power cable passes through
It is through at knife handle and is extended in perforation to one end and is electrically connected with point electrode.
The adjustable knife bar casts the knot that is integrally formed by memorial alloy as a further improvement of the utility model,
Structure.
The attraction flushing pipe and instillation pipeline are by polycarbonate injection moulded as a further improvement of the utility model,
Integrated formed structure.
Using the above structure, the beneficial effect is that:
Intermediate position offers cavity groove on the inside of the utility model ceramic head, and ceramic head one end is installed with adjustable knife bar simultaneously
Coupled, adjustable knife bar is an integral molding structure by memorial alloy casting, and memorial alloy can be according to different patients
Ear canal structure and lesion locations carry out bending and be adjusted, convenient for electrode knife head to the cuttings of pathological tissues, ablation and only
Blood only needs single scalpel, without other surgical instruments, without the ear canal structure and lesion locations according to different patients
It replaces the scalpel of suitable different model different size, saves the time of replacement scalpel, substantially reduce operation
Time, while the shape for making adjustable knife bar revert to script by heating adjustable knife bar after the completion of operation, peace
It is complete convenient；At least one perforation is offered in ceramic head, point electrode is plugged in perforation, and point electrode is in hook-shape structure, energy
It is enough so that point electrode to the pathological tissues of ear canal structure corners part carry out it is comprehensive cut off, point electrode bending angle
Degree is small in the range that 45 ° of -60 ° of designs enable to point electrode to act in cutting, enables to the amount of bleeding of tissue small, has
The precision and effect of the guarantee cutting of effect；Adjustable knife bar one end end cap is set in fixing piece, and fixing piece one end is equipped with knife handle
And connect with it in rotary separated, it is stronger to may make that fixing piece is connect with knife handle, while being easily installed and dismantling, outside knife handle
Surface is equipped with antiskid thread, and antiskid thread meets ergonomics, so that medical staff is stronger in grasping, it is effective to guarantee
The safety of operation.
