Description
Technical field
The present invention relates to medical instruments field, a kind of endoscope casing tube formula circular cutter is particularly related to.
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 in lacrimal passage under non-direct-view
Dredging or laser therapy easily cause the damage of lacrimal passage mucous membrane, in addition pierce through lacrimal passage formed via.The appearance of Lachrimal endoscope makes
The diagnosis and treatment for obtaining lacrimal passage disease have 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.
The content of the invention
The present invention proposes a kind of endoscope casing tube formula circular cutter, solves the problems, such as above-mentioned in the prior art.
The technical proposal of the invention is realized in this way：
A kind of endoscope casing tube formula circular cutter, including：
Circular cutter, including the head body portion connected with the head and the blade connected with the body portion；
Probe, through the head and the body portion and is movably arranged in the blade；
Wherein, the probe is matched as blunt circle head with the blade.
Preferably, the length in the body portion is 45~55mm, a diameter of 1~1.2mm in the body portion.
Preferably, the length in the body portion is 50mm, a diameter of 1.1mm in the body portion.
Preferably, the length of the blade is 1~3mm, a diameter of 1~1.2mm of the blade.
Preferably, the length of the blade is 2mm, a diameter of 1.1mm of the blade.
Preferably, the blade is open circles taper type.
Preferably, the probe is illumination probe.
Further, endoscope casing tube formula circular cutter of the present invention, also includes：
Length scale, is arranged in the body portion.
Beneficial effects of the present invention are：
Endoscope casing tube formula circular cutter of the present invention, in lacrimal passage disease examination, inserts a probe into circular cutter, makes two
Person's tight connecting is integral, and it is blunt circle head that now probe is matched with blade, and head end blunt circle, the sharp blade of circular cutter is not manifested
Come, so as to there is no any cutting safely and smoothly to insert lacrimal passage tissue to lacrimal passage tissue；When discovery stenosis of lacrimal passage or obstruction
During place, probe is exited into suitable distance, the blade for making circular cutter sharp is revealed, then by popping one's head under direct-view along tear
Road tube wall ring cutting pathological tissues back and forth, now circular cutter is the breakthrough in face, and functional diameter (FD) is big, pathological tissues scale off after by punching
Wash and can remove；Due to without laser or micro- brill dynamical system is needed, reducing unnecessary operation repeatedly and additional fire damage
Or mechanical damage；It is that circular cutter is directly sleeved in illumination probe to work when using, without the 3rd service aisle, can matches more
The illuminator of pixel high, improves operation definition, implements lacrimal passage ring cutting by probe and circular cutter and dredges plasty, there is provided
A kind of new Lachrimal endoscope menisectomy mode.
