Description
Technical field
This utility model relates to technical field of medical instruments, is a kind ofly to be used to guide colonoscope to advance the conduit of mirror in enteric cavity.
Background technology
Colonoscopy is a clinical very general inspection.Because the trend of colon has the big bending in many places, shank is very easy to form " button loop " at the intestinal knee in the colonoscope insertion process, causes colonoscope to advance the mirror difficulty.What this pusher colonoscope advanced that the mirror method extremely depends on the operator advances the mirror skill, even but skilled operators advance mirror certain difficulty also arranged.In March, 2006 " ENDOSCOPY " report colonoscope advances the mirror mortality and is approximately 5% one 20%.This push type advance the mirror method, also may cause malpracticees such as intestinal perforation.
Summary of the invention
The purpose of this utility model provides a kind of colonoscope and advances the mirror conduit, this conduit can insert from the biopsy hole of common colonoscope, and under the guiding of conduit, common colonoscope advances mirror along conduit, thereby become drawbacks such as button loop or perforation when avoiding into mirror, reach the purpose of advancing mirror smoothly.
This utility model is made up of guiding air bag, double channel catheter and tee T.Double channel catheter is made up of inner catheter and outer catheter.Inner catheter is elongated, and it is coniform that head is, and nose-circle is blunt, leads directly to the top of head in the pipe for inner chamber.Inner catheter is positioned at the outer catheter tube chamber, and the space between two pipes is an exocoel.The outer catheter front end is short than inner catheter, and by the sealing that links to each other of guiding air bag, the air bag blister cavities communicates with the exocoel of double channel catheter between the head trailing edge of its head end and inner catheter.The guiding air bag is one the thin-walled air bag of strong elasticity to be arranged, and is wasp waist shape depression in the middle of it during inflation.At the afterbody of double channel catheter, inner catheter passes and is fixed in this from the wall of outer catheter, and each joins interior outer catheter with a tee T.Inflate or aerofluxus for the exocoel of double channel catheter by tee T, so that the guiding air bag fills or dwindles; Also can perhaps inject or absorb the liquid of cleaning intestinal by the inner chamber injection or the interior gas of absorption intestinal of double channel catheter.During use, will insert anus with the air bag anus sleeve pipe of anti-gas-leak earlier, routinely common colonoscope be inserted in the rectum enteric cavity, again this utility model conduit be inserted the biopsy hole of colonoscope, and make the guiding air bag of conduit head end stretch out the front end of colonoscope.Then, give the guiding airbag aeration through exocoel, make airbag wall be close to intestinal wall by tee T.Flicking colonoscope control section gas injection button, injecting hole by colonoscope is to the enteric cavity gas injection, after enteric cavity is expanded to a certain degree, because it is external that anal orifice has the fixation balloon obstruction to prevent that gas from spilling, therefore with the increase of air pressure, guiding air bag cyst wall pressurized constantly moves forward along enteric cavity, drives conduit and extends forward, and colonoscope can be pushed ahead along conduit.Because the guiding airbag wall is smooth flexible, can not cause intestinal wall impaired.The air bag of wasp waist shape depression can prevent that like double barrier the gas that injects enteric cavity from leaking, thereby can guarantee that the colonoscope of air bag under clearing the way advances mirror speed.Colonoscope moves ahead along conduit not only can not abrade intestinal wall, and can stop into the appearance of situations such as button loop or intestinal perforation, and making into, mirror becomes smoothly and safety.If the gas obstruction is arranged in the intestinal before the guiding air bag or has filth to exist, then can be by the inner chamber aerofluxus or the cleaning of double channel catheter.When the intestinal mirror is advanced to caecum portion target endpoint, just can air bag be shunk by gas in the exocoel eliminating guiding air bag of double channel catheter, extract whole conduit from intestinal mirror biopsy hole again, surplus operation can be carried out inspection or treatments such as biopsy, cover bundle as common intestinal mirror.
This utility model is simple in structure, and is with low cost.When using clinically, need not change conventional intestinal mirror and work station thereof, not rely on operator's skill, improve safety and efficient that colonoscope advances mirror greatly, obviously alleviate patient's misery, and can reduce complication.

The specific embodiment
Now in conjunction with the accompanying drawings and embodiments, this utility model is described in detail.
This utility model is made up of guiding air bag 1, double channel catheter 2 and tee T 3,4.Double channel catheter 2 is made up of outer catheter 6 and inner catheter 7.Inner catheter 7 is elongated, and head 5 is coniform, and nose-circle is blunt, leads directly to the top of head 5 in the pipe for inner chamber.Inner catheter 7 is positioned at the tube chamber of outer catheter 6, and the space between two pipes is an exocoel.Outer catheter 6 front ends are short than inner catheter 7, and by the sealing that links to each other of guiding air bag 1, air bag 1 blister cavities communicates with the exocoel of double channel catheter 2 between head 5 trailing edges of its head end and inner catheter.Guiding air bag 1 is one the thin-walled air bag of strong elasticity to be arranged, and is wasp waist shape depression in the middle of it during inflation.At the afterbody of double channel catheter 2, inner catheter 7 passes and is fixed in this from the wall of outer catheter 6, and inside and outside tail end of conduit joins with tee T 3,4 respectively.Inflate or aerofluxus for the exocoel of double channel catheter 2 by tee T 3, so that guiding air bag 1 fills or dwindles; Can give the inner chamber injection of double channel catheter 2 or absorb gas in the intestinal by tee T 4, perhaps the liquid of intestinal is cleaned in injection or absorption.As shown in Figure 4, during use, to insert anus with the anus sleeve pipe 12 of anti-gas-leak fixation balloon 11 earlier, routinely common colonoscope is inserted in the rectum enteric cavity, inflate to stop up anus by 10 pairs of fixation balloons of tee T 11, again this utility model conduit is inserted the biopsy hole 9 of colonoscope, and make the guiding air bag 1 of conduit head end stretch out the front end of colonoscope.Then, give the guiding air bag 1 inflation through exocoel, make airbag wall be close to intestinal wall by tee T 3.Flicking colonoscope control section 8 gas injection buttons, injecting hole by colonoscope is to the enteric cavity gas injection, after enteric cavity is expanded to a certain degree, because it is external that anal orifice has fixation balloon 11 obstructions to prevent that gas from spilling, therefore with the increase of air pressure, guiding air bag 1 cyst wall pressurized constantly moves forward along enteric cavity, drives conduit 2 and extends forward, and colonoscope shank 13 can be pushed ahead along conduit 2.Because guiding air bag 1 cyst wall is smooth flexible, can not cause intestinal wall impaired.The air bag 1 of wasp waist shape depression can prevent that like double barrier the gas that injects enteric cavity from leaking, thereby can guarantee that the colonoscope of air bag 1 under clearing the way advances mirror speed.Colonoscope moves ahead along conduit 2 not only can not abrade intestinal wall, and can stop into the appearance of situations such as button loop or intestinal perforation, and making into, mirror becomes smoothly and safety.If the gas obstruction is arranged in the intestinal before the guiding air bag 1 or has filth to exist, then can be by the inner chamber aerofluxus or the cleaning of double channel catheter 2.When the intestinal mirror is advanced to caecum portion target endpoint, just can air bag be shunk by gas in the exocoel eliminating guiding air bag 1 of double channel catheter 2, extract whole conduit from intestinal mirror biopsy hole 9 again, surplus operation can be carried out biopsy, cover bundle etc. and check or treatment as common intestinal mirror.
Embodiment 1: a kind of colonoscope advances the mirror conduit
According to the colonoscope different model, the colonoscope that can be made into corresponding different model advances the mirror conduit.
