Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to choledochoscope guide in a kind of laparoscopy.
Background technology
Choledochoscope inspection is the effective ways that biliary tract disease checks, its apparatus have rigid mirror and soft mirror point, firmly
Formula mirror can only observe common bile duct, and scope can be delivered to 2～3 grades of common hepatic ducts by soft mirror, therefore use soft choledochoscope the most more.Logical
The mode of often choledochoscope entrance biliary system has two kinds: cut insertion, biliary tract after common bile duct in abdominal or laparoscopic surgery
Postoperative through T-shaped pipe sinus tract entrance bile duct.
In operation on biliary tract, the more understanding biliary system situation persons of palpus, such as: with or without calculus of intrahepatic duct, narrow, tumor；Always
Bile duct hypomere is the most unobstructed, with or without calculus, narrow, tumor, all can carry out choledochoscope inspection in art.
At present, in art, choledochoscope inspection comprises the following steps: (1) in the case of ductus choledochus fully exposes, before common bile duct
Wall does the stringer otch of an about 1cm length, sends into choledochoscope through this otch and detects biliary tract.The most upwards detect common bile duct, left and right
Common hepatic duct, detects common bile duct and Vater ampulla still further below.For making to get a clear view, it is necessary to ceaselessly irrigate in bile duct through choledochoscope
Sterile saline, because the saline injected can flow to intraperitoneal through common bile duct otch, therefore the water flowed out must be inhaled by assistant at any time
Only.(2), time as found tumor or needing biopsy, biopsy forceps pincers can be sent into through choledochoscope pincers deferent and take tumor tissues, send pathology to examine
Looking into (3) has calculus, available basket to directly take out in finding bile duct, or after determining calculus position, exits choledochoscope, guides art
Person takes stone with surgery special vice.(4) as found stenosis of common bile duct, air bag can be sent into, to narrow under direct-view through choledochoscope pincers deferent
Expand for narrow section.(5) every checked after, exit choledochoscope, continue surgical operation.
In art, choledochoscope inspection is compared more much more difficult with postoperative choledochoscope.Postoperative choledochoscope: common bile duct places T-shaped pipe,
Due to surrounding tissue and the parcel that oozes out fiber around postoperative T pipe, forming sinus tract, in postoperative February, tunnel is firm, extracts T
Pipe, carries out choledochoscope inspection through sinus tract and takes stone, and owing to there being the support of sinus tract, choledochoscope can convenient, repeatedly, quickly pass in and out biliary tract,
Under normal saline flushing, having the sealing process of sinus tract, bile duct can well be expanded, and gets a clear view, and choledochoscope inspection, takes stone energy
It is easily accomplished.Choledochoscope in art: in laparoscopy, choledochoscope inspection takes stone, owing to lacking support and closing, the gallbladder of T pipe sinus tract
Road mirror shank is soft, transmits difficulty in vivo, enters biliary tract by bile duct opening and becomes extremely difficult, often needs to help hand instrument
Clamp auxiliary turnover biliary tract, is so easily damaged the plastic peel of choledochoscope head, and is difficult to keep coordinating system with operator
One.And the normal saline rinsed can go out from slit flow between choledochoscope and bile duct, and biliary tract can not well be expanded, and the visual field becomes mould
Sticking with paste unclear, so choledochoscope inspection in art, to take stone difficulty very big, the time is long, and operator is the most tired.
Summary of the invention
According to above the deficiencies in the prior art, the present invention provides choledochoscope guide in a kind of laparoscopy, can be easily
Guiding choledochoscope to pass in and out bile duct in laparoscopic surgery, have the closing of air bag, biliary tract can fully be expanded, and gets a clear view, and allows abdominal cavity
Choledochoscope inspection in mirror art, take stone and become convenient, easy, shorten the choledochoscope review time, lower the manipulation strength of operator.
Choledochoscope guide in a kind of laparoscopy of the present invention, it is characterised in that: this guide is saved spiral section by n
The tubular structure being formed by connecting, the cross-sectional structure of described spiral section includes two horizontal segments being positioned at Different Plane and company
Connecing the changeover portion between two horizontal segments, the described horizontal segment being positioned against medial plane is extended with pressing part A to inner side, described
The horizontal segment being positioned against inner side plane be extended with pressing part B laterally, pressing part A and the adjacent spiral shell of described arbitrary spiral section
The pressing mutual pressing of part B of rotation section, the pressing part B of described arbitrary spiral section and the pressing mutual pressing of part A of adjoining spiral section；
Being provided with cylindrical airbag on described guide tail end outer wall, described cylindrical airbag connects appendix, and described is defeated
Trachea is arranged along guide outer wall.
In the present invention, guide connects between bile duct and stomach wall, primarily serves choledochoscope and guides the effect supported, needs
Having certain intensity and also can bend, although traditional silica gel tube can bend but intensity is low, it is impossible to have choledochoscope
The guiding of effect.Therefore, on structure designs, take n joint spiral section to be laminated and form, along caliber axle between adjacent spiral section
Line direction is rigidity, is unlikely to deform, but can deform upon with stress in a direction perpendicular to the axis, thus meets existing
Certain intensity and also can bend.The part being placed in common bile duct, cylindrical airbag expands after appendix gas injection, will draw
Lead device to be fixed on common bile duct inwall, and also the saline being prevented from injecting can flow to intraperitoneal through common bile duct otch, fully
Expansion extrahepatic duct, it is ensured that get a clear view.
Wherein, the preferred version of the present invention is as follows:
The internal diameter of described guide is 8mm.
Described spiral section uses galvanized steel, rustless steel or aluminium alloy to be made.
Described guide internal channel is provided with 1～3 rubber septum, and each rubber septum is provided with cross-cut, its
In, preferred scheme is for being provided with 2 rubber septums, and the spacing distance of 2 rubber septums is 2～3cm.Choledochoscope is through cross
Incision site through rubber septum continue inwardly into, owing to laparoscopic surgery needing do artificial pneumoperitoneum, therefore, add rubber
Partition primarily serves the effect preventing gas leak.
Described guide is provided with peritoneoscope stamp card with the outer wall of contact human skin position, and peritoneoscope stamp card is used for
By fixation between guide and stomach wall, prevent from operating process occurs bigger displacement.
It is an advantage of the current invention that: (1) guide takes the mode of the mutual pressing of more piece spiral section to be formed by connecting, and defines
There is certain intensity can bend again, it is provided that the pull strength in choledochoscope bootup process, again can according to enter internal enter
The certain adaptive angle adjustment of row；(2) guide can be fixed on common bile duct inwall by cylindrical airbag, and also can
Prevent the saline injected from can flow to intraperitoneal through common bile duct otch, fully expand extrahepatic duct, it is ensured that get a clear view；(3) draw
Lead whole during simple to operate, the shortest, the labor intensity of operator is greatly reduced, shortens the operating time, improve
Work efficiency；(4) guide cost of manufacture is low, draws materials conveniently, can use after carrying out sterilization before using.
