Description
Technical field
The present invention relates to the field of medical instrument technology, especially a kind of incision knife and its application method.
Background technique
Incision knife is widely used to medical field, especially in Minimally Invasive Surgery in use, since its cutter head is unique
Moulding and size are small, and have coagulation effect, can be more accurate to the assurance of size when cutting tissue film, and guarantee
The safety and stability of Minimally Invasive Surgery.
Existing monopole incision knife, the main connection type fixed using cutter head and syringe needle, syringe needle cannot be transported in cutter head
It is dynamic, and since cutter head needs to carry out coagulation operation, syringe needle is usually mounted in cutter head plane, therefore, cutter head is being resisted tissue
When surface is injected, needing firmly to press cutter head makes cutter head submerge organization internal, to provide biggish injection pressure for syringe needle
Power is to pierce through tissue surface.
Above-mentioned existing incision knife design has the following deficiencies: that syringe needle cannot be moved with respect to cutter head, can not adjust coagulation with
The relative position of cutter head and syringe needle, inconvenient during injection two；The design that syringe needle is located in cutter head plane can not be not
Syringe needle is smoothly inserted into organization internal in the case where firmly pressing；Firmly pressing cutter head guarantees that syringe needle pierces through tissue surface, is easy
The injury to tissue bottom is caused, and strength is difficult to grasp, it is more demanding to the proficiency of user, it is with higher to use wind
Danger.
And existing adjustable incision knife, although being not fixed using cutter head and syringe needle, syringe needle can move in cutter head,
It is when syringe needle and cutter head move, to need to operate mobile core bar part, then the conducting wire on electrode tip will be with core bar
Movement and move, cause falling off between conducting wire and electrode tip.
Summary of the invention
The object of the present invention is to provide a kind of incision knife, following defect existing for existing incision knife can solve: in syringe needle
With cutter head movement when, need to operate mobile core bar part, then the conducting wire on electrode tip will with the movement of core bar and
