Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to a kind of polyp withdrawing device of endoscope.
Background technology
Endoscope is a kind of common medical instrument, and what is used at present is mostly fujinon electronic video endoscope, and fujinon electronic video endoscope generally wraps
It includes：External light source, scope and attached mechanical composition, wherein, scope include sequentially connected front end, bending section, insertion tube,
Operation portion, the guide-lighting optical cable for meeting mesh portion and being connect with external light source.Front end is the hard component of scope, equipped with multiple apertures and
Window, respectively aspirated and water sending outlet opening, biopsy channel outlet opening, object lens and guide-lighting window.Crooked position is in front end and insertion tube
Between, the multi-angle observation to realize front end can be bent to different directions.Insertion tube inner containment has and aspirated and water sending
The aspirated and water sending valve passage of outlet opening thereof, the light being connect with the biopsy channel of biopsy channel outlet opening thereof, with guide-lighting window
Light guide bundles and the image guide bundles being connect with object lens.In use, by scope front end, bending section and the insertion tube of endoscope through human body
Natural hole or the small notch done of underwent operative enter in human body, can directly pry through the variation in relation to position.Scope at present
Biopsy channel opening be respectively positioned below operation portion, be biopsy forceps and various treatment instrument inserting ports, biopsy forceps and various control
Treatment is stretched out after being inserted into instrument by biopsy channel from the biopsy channel outlet opening of front end.
Polyp, refers to the extra swollen object that human tissue surface grows, and modern medicine is usually being grown in human body mucomembranous surface
On neoplasm be referred to as polyp.Suffer from polypiferous patient, generally extract and cut through high-frequency electrical under endoscope (such as Gastrointestinal Endoscopes)
Pathological biopsy is carried out except postoperative polyp needs whole knurl to take out.And the biopsy channel aperture of common fujinon electronic video endoscope generally exists
2.8mm-3.5mm can only take out the polyp that diameter is less than 5mm；It is more than the polyp of 5mm for diameter, is plucked at present in Microendoscopic
During except polyp, need to through it is special grab object pincers enter human body in take out or through vacuum suction scope front end object lens minute surface, with interior
Mirror front end exits；The polyp of part excision slips into enteric cavity, it is difficult to capture, doctor abandons capturing, it is desirable that patient is noticed with stool
It excretes, then send biopsy；And for polyposis, it is removed in endoscope incision, after crawl polyp is needed to exit scope, again
Into mirror, second piece of polyp is found, cuts off, passes in and out repeatedly again, increased patient's pain, while operation delay, cause many inconvenience.
Utility model content
The utility model takes out time-consuming, inconvenient and increase patient's pain to solve the lower polyp of current endoscope treatment
The problem of bitter, provides a kind of polyp withdrawing device of endoscope, it is suitable for the taking-up of multiple, larger polyp, for it is multiple, compared with
The excision of big polyp provides convenient, effective mode.
In order to realize the utility model aim, the utility model devises following technical solution：
A kind of polyp withdrawing device of endoscope, including：Circular pipe ontology, described this body sidewall of circular pipe be equipped with
The parallel slit of circular pipe axis, the slit since the nozzle of circular pipe ontology one end, the length of the slit with
The scope front end of endoscope, bending section are consistent with the total length of insertion tube three；The circular pipe ontology with slit one
End pipe mouth is equipped with hyaline cap, and the other end is held round pipeline；The described one end of circular pipe ontology with slit from pipe to nozzle
