Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of magnetic kiss being applicable to Cholangio-jejunostomy under peritoneoscope
Clutch.
Background technology
In many operations of Genneral Surgery, carry out coincideing to bile duct and small intestinal and recover gastral seriality to operation extremely
Close important.And the size of abdominal incision brings different mental pressure to patient, and affect patient's recovery and quality of life.Abdominal cavity
Mirror technology is a kind of Minimally Invasive Surgery technology, and its appearance avoids the drawback of the big otch of tradition hepatobiliary surgery, the most more meets careful
Aesthstic requirement.But, carry out biliary enteric anastomosis under current peritoneoscope and still use traditional method (i.e. suture), be
The operation of one great difficulty, postoperative there are the complication probabilities such as anastomotic leakage, anastomotic stricture, anastomotic stoma foreign body residual very
Height, often jeopardizes patient vitals.Even if the doctor through specialty laparoscopic technique training for many years completes abdominal cavity with absorbable suture
Mirror biliary enteric anastomosis, however it remains higher complication rate.Therefore, under peritoneoscope, suture carries out biliary enteric anastomosis and exists
Clinical practice application is extremely restricted, it is difficult to promote.Magnetic pressure squeezes the one that anastomosis is squeezing anastomosis, to be anastomosed
The identical pressure of tissue is provided by magnetic force, and anastomotic stoma is coincide tightly after being formed and foreign residual.Domestic and international many passes magnetic pressure is squeezed
For the experiment coincideing and application confirm that magnetic pressure squeezes the more traditional anastomosis of anastomosis repeatedly, there are quick, safety, anastomotic stoma
The advantages such as foreign residual, anastomotic stricture and anastomotic leakage incidence rate are low.
But there is no at present for use under the peritoneoscope designed by this special art formula of biliary enteric anastomosis under peritoneoscope
Gallbladder intestinal magnetic coinciding machine, thus gallbladder intestinal magnetic this technology of coincideing cannot be allowed to be widely popularized and benefit patient all over the world.

Magnet ring the 1, first magnetic shield shell 3 being partially embedded outside bile duct 21 intracavity, the only portion distal end of central canal 5 in addition to central canal 5
Dew；
Second step (Fig. 7): the fixing shell 6 of the second magnet ring 2 body is connected solid with the anastomat bar end of operation handle 7
Fixed；Then insert via the stump opening of the intestinal tube 22 of small intestinal, make puncturing lever 18 be stabbed out by the intestinal wall of intestinal tube 22 to be anastomosed；
3rd step (Fig. 8): the first magnetic shield shell 3 making puncturing lever 18 expose after embedding with bile duct 21 purse string suture exposes
Central canal 5 connects fixing；Rotating threaded adjusting handle 13 can make puncturing lever 18 drive first magnet ring the 1, first magnetic shield shell 3 to come and go
Motion；When, after bile duct 21 stump with intestinal tube 22 stump sidewall patch jail, pressing magnet ring release lever 12 makes magnet ring release lever 17 move forward,
Triggering lever spline structure 20 extrudes the tuning fork-like structure of puncturing lever 18 and is allowed to shrink disengaging in central canal 5；Continue pressing magnet ring
Release lever 12 makes magnet ring release lever 17 continued advancement, contacts the second magnetic shield shell 4, promotes the second magnetic shield shell 4 to make it from solid
Determine shell 6 departs from；I.e. first magnet ring the 1, first magnetic shield shell the 3, second magnet ring the 2, second magnetic shield shell 4 and 7 points of handle of operation
From, so far complete to coincide；
As it is shown in figure 9, after having coincide, remain first magnet ring the 1, first magnetic shield shell the 3, second magnet ring 2 at anastomotic stoma
(2), the second magnetic shield shell 4 magnetize squeezing coincide effect, the remaining component of device exits with operation handle 7 and takes out of；When coincideing
After mouth healing, first magnet ring the 1, first magnetic shield shell the 3, second magnet ring the 2, second magnetic shield shell 4 is tear-away, gets rid of with intestinal peristalsis promoting
External, reach anastomotic stoma foreign and coincide.
A kind of magnetic anastomat being applicable to Cholangio-jejunostomy under peritoneoscope of the present invention, by squeezing anastomosis and abdomen by magnetic pressure
Chamber mirror technology designed in conjunction go out gallbladder intestinal magnetic stapling apparatus under a kind of peritoneoscope, Sutureless gallbladder intestinal quick, reliable kiss can be realized
Close.The use of this device can reduce the operation easier realizing Cholangio-jejunostomy under peritoneoscope, increases processing safety；Avoid simultaneously
Tradition is coincide anastomotic stoma foreign body that method causes, anastomotic stricture, anastomotic leakage, the generation of the complication such as Anastomotic bleeding.Should
Device realize gallbladder intestinal magnetic coincide after, operation handle 7 can be taken off sterilization after Reusability, can reduce medical treatment cost, save doctor
Treat resource；Magnet ring can excrete simultaneously, internal without metal object residual, makes patient be benefited and maximizes.
Above in conjunction with embodiment, the present invention done further narration, but the present invention has been not limited to above-mentioned embodiment,
In the ken that one skilled in the relevant art is possessed, it is also possible to make on the premise of without departing from present inventive concept
Various changes.
