Description
Technical field
This utility model relates to a kind of recoverable support, particularly a kind of through the special recyclable overlay film frame of natural tract endoscopic surgery, belongs to medical instruments field.
Background technology
Through natural tract endoscopic surgery (naturalorificetransluminalendoscopicsurgery, hereinafter referred to as NOTES) be a new term, namely insert soft scope through the natural duct of health, insert through scope mine the operation that operation equipment carries out outside digestive tract wall by its otch.Popular saying is exactly that gastroscope enters esophagus, stomach by oral cavity, and coat of the stomach is made a call to a hole, and gastroscope enters abdominal cavity by this hole, completes the surgical operations such as gallbladder removal, and the gallbladder of excision is all taken out by oral cavity through stomach, esophagus.Closed the otch on coat of the stomach by methods such as metal clips, finally withdraw from gastroscope.
First the advantage of NOTES operation is definitely do not have cicatrix, while obtaining gratifying beauty treatment and psychological Wicresoft effect, the unnecessary wound that conventional surgical and laparoscopic surgery cause can be reduced, alleviate postoperative pain, and avoid infection of incisional wound, incisional hernia and chronic stomach wall pain.With open compared with abdomen or laparoscopic surgery, NOTES operation contact less to peritoneum with abdominal viscera, the peritoneum reaction that causes of performing the operation is comparatively light, and the chance of postoperative ileus, intestinal adhesion generation significantly reduces.Post-operative recovery time is short, reduces medical expense.Current remedial endoscopic can carry out only using under tranquilizer, and therefore, clinical NOTES operation has completely likely come without tracheal intubation and general anesthesia, alleviates depth of anesthesia, corresponding anesthetic risks also reduces greatly.The high obesity patient that NOTES also cannot treat for routine operation and high-risk, unsound special sufferer provide operative treatment may.
The method entering abdominal cavity conventionally by gastral cavity utilizes needle-like electric knife to puncture on coat of the stomach, then with sphincterotome or balloon dilation otch, also some other technological means is had to carry out the puncture of gastral cavity ostomy, no matter but which kind of mode all needs the holostrome of coat of the stomach to cut, wound is relatively large, the muscle layer of coat of the stomach is cut off, in addition electric knife burning wound, and these all affect closed effect at a specified future date.The otch of NOTES is different from abdominal and laparoscopic surgery, and the former carries out under nonsterile conditions, and the latter aseptically completes.In the process of operation, the gastrointestinal wall cut closure of NOTES sternly will not cause gastro-intestinal Fluid person who lives in exile abdominal cavity, cause abdominal cavity infection, peritonitis, and even intra-abdominal abscess is formed.In addition in the process of the last closed coat of the stomach wound of operation, because wound may be comparatively large, closed difficulty can cause wound healing slowly easily to occur to infect and fistula.Enter then can solving the problem of abdominal cavity by coat of the stomach, but be not specifically designed to the device importing scope at present.
Utility model content
Summary of the invention
The purpose of this utility model is, there is provided a kind of through the special recyclable overlay film frame of natural tract endoscopic surgery, solve the difficult point entering abdominal cavity technology and closure techniques through natural tract endoscopic surgery, for the development through natural tract endoscopic surgery from now on provides an optimal platform.
The technical solution of the utility model: a kind of through the special recyclable overlay film frame of natural tract endoscopic surgery, it is characterized in that: comprise metal rack and overlay film, the passage that can pass through for scope is formed in this metal rack, wherein, pellosil is provided with in metal rack, the center of pellosil is provided with opening, this opening passes for scope, and this open design becomes when scope passes Silicon moulds by this opening, this pellosil can be tighter what wrap around scope cable, at utmost to prevent pellosil as the water on these barrier film both sides of barrier film or mutually ganging up of vapour.
Advantageously, aforementioned opening is the opening being slightly less than scope cable, this be conducive to barrier film by the gas of barrier film or water mutually isolated.
Advantageously described opening is a kerf further, and this otch is formed as unconspicuous finedraw when scope does not pass.
In addition, described opening can be poroid.
Advantageously, the two ends of described metal rack are horn mouth shape.This is conducive to the discrepancy of scope.
In addition, one end of described metal rack is connected with draught line.This is conducive to the support described in traction.
It is advantageous that described metal rack is made up of the B alloy wire being woven into pipe network structure, overlay film is wrapped in outside metal rack.
As for material aspect, the material of described overlay film is politef, terylene, polyester or polyurethane.
And the material of described metal rack is Ti-Ni alloy.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, the diameter of described through hole is 6mm ~ 8mm.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, the diameter of described through hole is 6-8mm.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, the material of described overlay film is politef, terylene, polyester or polyurethane.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, the material of described metal rack is Ti-Ni alloy.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, under duty, the tube chamber portion diameter of metal rack is 10mm ~ 13mm, and the horn mouth diameter at two ends is 13-15mm.
The diameter of the through hole on described pellosil is 6-8mm, metal rack official jargon diameter 10-13mm, horn mouth diameter 13-15mm.
Aforesaid in the special recyclable overlay film frame of natural tract endoscopic surgery, under duty, the tube chamber portion diameter of metal rack is 12mm, and the horn mouth diameter at two ends is 15mm.
Compared with prior art, this utility model using self-inflated metal rack as importing the innovation that device that scope enters abdominal cavity is this case, namely expand after metal rack passes through coat of the stomach and set up operative approach and guarantee scope smoothly by metal rack inner chamber, its advantage is:
(1) reduce to greatest extent to the wound of digestive canal wall and blood vessel injury hemorrhage: the holostrome not needing to cut coat of the stomach, seal wire through entering abdominal cavity sends into support, the passage between stomach and abdominal cavity is set up in expansion by means of support, damage for coat of the stomach is minimum, muscularis propria is only subject to the expansion of support and opens (not from disconnected muscle bundle), and the reparation of postoperative muscularis propria is rapid.
(2) scope can enter abdominal cavity freely through metal rack inner chamber, and scope is handling stronger;
(3) make the closure techniques of otch more easily, effect is more reliable: metal rack can be extracted by draught line at any time after completing dependent diagnostic, biopsy or therapeutic procedure, and exit scope.Due to the method and traditional coat of the stomach window and blunt separation to set up the method for operative approach different, after extracting metal rack, local mucous layer cut is regular, is easy to Titanium clip folder under scope and closes stitching.
(4) the different site of puncture of gastric can be selected to adapt to the needs of intraperitoneal different operating: as detected for abdominopelvic cavity, peritoneal biopsy and appendectomy etc. can select traditional body of stomach antetheca point of puncture; Gallbladder removal can select gastric antrum antetheca less than normal curved, imports soft scope can to go directly margo interior hepatis cholecyst bed by metal rack, does not need the inverted status keeping gastroscope, more easily carries out operation on gallbladder and liver biopsy; Pancreatic surgery can select body of stomach rear wall entrance, has and enters by recoverable metal support the successful case that pancreatic abscess carries out debridement.
