Description
Technical field
The present invention relates to a kind of auxiliary facilities for colonoscopy, be specifically related to colonoscope Multifunctional coat pipe device.
Background technology
Existing colonoscope is soft scope, when by crooked positions such as sigmoid colon, splenic flexure, hepatics flexure of colon, scope easily forms curved button loop, the endoscopic surgery for nose gastroscope of performance delicate: with nose gastroscope be intestinal mirror person under inspection almost no pain more easily bend into button loop, cause difficulty can to the insertion of scope.The cavity method of seeking of colonoscope is divided into water injection type and gas injection type two kinds.When in intestinal, water injection rate is too much, liquid can be discharged by anus, causes the clothing of examinating couch and person under inspection contaminated.Inflate too much person under inspection when intestinal tube and can think that abdominal distention is uncomfortable.
Summary of the invention
The present invention in order to solve soft scope enter in mirror process pollute examinating couch especially by easily forming curved button loop during sigmoid colon position and causing liquid to be discharged by anus to water filling in enteric cavity, clothing and gas injection too much can bring abdominal distention discomfort problem to person under inspection, colonoscope Multifunctional coat pipe device is provided.
Colonoscope Multifunctional coat pipe device of the present invention comprises trocar sheath, four-way pipe and the first steel wire, described first steel wire spiral is arranged in the wall thickness of trocar sheath, four-way pipe is arranged on the lower end of trocar sheath, four-way pipe and trocar sheath tight fit connection, the upper end of described trocar sheath is provided with inclined-plane, the oblique angle on described inclined-plane is 30 ° ~ 60 °, described outer sleeve upper sidewall is provided with conduction hole, described four-way pipe axially opens flexible pipe by first, first slide fastener, first point of flexible pipe and second point of flexible pipe composition, first slide fastener is arranged on the axial open end that first axially opens flexible pipe, first slide fastener axially opens flexible pipe composition sealed tube by first, first point of flexible pipe and second point of flexible pipe are arranged on the both sides of sealed tube, and first point of flexible pipe and second point of flexible pipe and first axially open flexible pipe make one.
The present invention has following beneficial effect:
One, the liquids and gases crossed in person under inspection's intestinal are discharged through outside drainage tube by four-way pipe by the present invention, balance the liquids and gases pressure in intestinal; To avoid in intestinal water injection rate too much, liquid can be discharged by anus, causes the contaminated problem of the clothing of examinating couch and person under inspection and avoids the problem that gas in intestinal too much causes person under inspection's abdominal distention to be suffered from abdominal pain.
Two, the elastic resistance that trocar sheath is suitable can be complied with scope and be slided, the elastic resistance can resisting intestinal tube makes trocar sheath can form one relatively without the stable passage of curved button loop in straight-ethyl-descending colon region, scope can not form curved button loop, and scope is easily inserted to ileocecus by difficult position.
Three, when meeting special circumstances transverse colon or the relatively tediously long person under inspection of sigmoid colon then can use air bag, filled up by air bag by gas injection conduit, make air bag relative with intestinal tube fixing, pulling back, trocar sheath can shorten, cut-off intestinal tube.Trocar sheath can form a metastable passage in enteric cavity, helps scope and inserts ileocecus, makes to operate the discomfort not only becoming smoothly but also alleviate patient.
Four, the invention solves the closed type trocar sheath laid in advance before scope inserts and partially grow, affect scope performance, cause unhandy problem to operator.Solve the problem that can not extend as required after partially short trocar sheath inserts.
