Description
Technical field
The utility model is related to medical instruments field, particularly relates to a kind of endoscope casing tube formula circular cutter.
Background technology
Lacrimal passage disease is ophthalmology frequently-occurring disease, and current primary treatments are lacrimal passage dredging plasty, dacryocystorhinostomy
With lacrimal passage by-pass operation etc..Wherein lacrimal passage dredging plasty is the most minimally invasive side taken on original lacrimal passage structure is not changed
Method, is clinically widely used at present.
Traditional lacrimal passage dredges plasty due to technology and the limitation of operating equipment, is blindly carried out under non-direct-view in lacrimal passage
Dredging or laser therapy easily cause the damage of lacrimal passage mucous membrane, in addition pierce through lacrimal passage formation via.Lachrimal endoscope makes
Obtaining the diagnosis and treatment of lacrimal passage disease has breakthrough progress.Under Lachrimal endoscope, can routinely carry out Laser surgery for lacrimal duct obstruction and
Miniature electric drill lacrimal passage plastic surgery.By Lachrimal endoscope, lacrimal passage mucous membrane can be looked at straight and positioning and qualitative is carried out to lesion, used
Laser and Miniature electric drill at utmost reduce Lacrimal path damage, the risk via formation, so as to obtain more minimally invasive in direct-view menisectomy
More effective therapeutic effect.
But laser and electric drill plasty are only drawback is that the two is put in lesion under Lachrimal endoscope
Break through, need to adjust energy multi-pass operation repeatedly for the extensive person of lesion, additional injury easily is had to surrounding tissue, while this
Two kinds of operations are preferable to lacrimal passage centre stenosis or occlusion effect, and not easy to operate for lesion around, are additionally inserted into lacrimal passage group
Knitting may be to lacrimal passage organizational composition cutting damage.
