Abstract

The utility model provides a formula stomach liver that prevents shifting support that coincide, include: the support body, the one end of support body has stomach expansion end, extends to the stomach, and the other end of support body has liver's on -expansible end, extends to the liver. One side that the support body is close to stomach expansion end sets up the film body on the surface. The support body is close to one side surface of liver's on -expansible end does not smoothly have the attachment. The utility model discloses the radial expansion structure of outwards extending ring shape flange of stomach expansion end for following the support body of support body, it is reliable and stable to make the support place, prevents to the liver internal shift. The utility model discloses formula stomach liver that prevents shifting support that coincide adopts half tectorial membrane structure, and the support body sets up the film body near one side of stomach expansion end on the surface promptly, and the side surface that the support body is close to liver's on -expansible end does not set up the film body, can prevent effectively that the support from to the stomach internal shift, can prevent effectively also that the support is to liver internal shift, stabilizing support position.

Description

A kind of anti-displacement formula stomach liver anastomosis bracket
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of anti-displacement formula stomach liver anastomosis bracket.
Background technology
Obstructive jaundice is common clinical, and its main cause includes calculus of bile duct, bile duct injury, cancer of biliary duct, cancer of pancreas, hepatocarcinoma, duodenal carcinoma, metastatic carcinoma, chronic pancreatitis and parasite etc. For release block Main Means include operation, percutaneous transhepatic puncture drain (PTCD) and through duodenoscope drive in the wrong direction bile duct (ERCP) drainage. Operative treatment wound and risk are all relatively big, for the patient that primary affection cannot excise, are generally left out using the mode of operation to release and block. PTCD is easy and simple to handle, it is easy to be accepted by patients, but long-term drainage, bile loss causes severe electrolyte, weakens intestinal mucosa defense function, affects digestive function. And external drainage nursing is loaded down with trivial details, easily occurs to infect and de-pipe, should not place for a long time. Occur that as patient during the complication such as ascites, external drainage treatment is taboo. Studying proof at present, be a kind of method being more suitable for Preserving time drainage system through the inner drainage treatment of human body natural's path, therefore ERCP currently progressively becomes the first-selected therapeutic modality releasing obstructive jaundice. What intubate for experienced scope doctor ERCP is that mortality can reach 3%-5%. When patient exists topography variation, operation change gastrointestinal tract structure, duodenum or stenosis of bile duct, mortality will be higher. When after intubation defeat patient again by face PTCD or surgical operation drain.
The metal rack puncture drainage that starts to be applied between digestive tract and biliary tract over nearly 5 years, treats malignant obstructive jaundice. Make this technology be expected to become except ERCP another kind of efficiently, the inner drainage treatment mode of Wicresoft. And the metal rack not still being suitable at present coincide for stomach liver, the incidence rate of conventional stent displacement is high.
Summary of the invention
Utility model purpose: technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that a kind of anti-displacement formula stomach liver anastomosis bracket.
In order to solve above-mentioned technical problem, this utility model provides a kind of anti-displacement formula stomach liver anastomosis bracket, including: rack body, one end of rack body has stomach expansion end, extending to stomach, the other end of rack body has liver's on-expansible end, extends to liver.
Further, described rack body is cylindrical mesh structure.
Further, described stomach expansion end is the expansion structure of the annular flange that extends radially outwardly out along rack body.
Further, described rack body arranges film body on a side surface of stomach expansion end.
Further, described rack body near the side smooth surface of liver's on-expansible end without attachment.
Further, described anti-displacement formula stomach liver anastomosis bracket is metal material.
Beneficial effect:
1, the stomach expansion end of this utility model rack body is the expansion structure of the annular flange that extends radially outwardly out along rack body, it is possible to support is placed reliable and stable, it is prevented that to liver internal shift.
2, this utility model anti-displacement formula stomach liver anastomosis bracket adopts half structure of film, namely rack body arranges film body on a side surface of stomach expansion end, and rack body is not provided with film body near a side surface of liver's on-expansible end, can effectively prevent support from shifting to gastric, also can effectively prevent support to liver internal shift, center rest position.
3, this utility model anti-displacement formula stomach liver anastomosis bracket can reduce patient's misery in malignant biliary obstruction is treated, and extends patient's life span.
4, this utility model anti-displacement formula stomach liver anastomosis bracket applied range, easy to operate.
5, this utility model anti-displacement formula stomach liver anastomosis bracket simple in construction, easily manufactured, one-shot forming, it may be achieved large-scale industrial production, less costly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments this utility model being done and further illustrate, of the present utility model above-mentioned or otherwise advantage will become apparent.
Fig. 1 is the anti-displacement formula stomach liver anastomosis bracket structural representation of this utility model embodiment, wherein, 1-rack body, 2-film body, 3-stomach expansion end, 4-liver on-expansible end.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is elaborated.
As it is shown in figure 1, a kind of anti-displacement formula stomach liver anastomosis bracket, including: rack body 1, one end of rack body 1 has stomach expansion end 3, extends to stomach, and the other end of rack body 1 has liver's on-expansible end 4, extends to liver.
Anti-displacement formula stomach liver anastomosis bracket is metal material. Rack body 1 is cylindrical mesh structure.
Stomach expansion end 3 is the expansion structure of the annular flange that extends radially outwardly out along rack body 1.
Rack body 1 arranges film body 2 on a side surface of stomach expansion end 3, for preventing the support in liver from coming off and shifting, and center rest position. Rack body 1 without attachment, is not provided with film body 2 near the side smooth surface of liver's on-expansible end 4.
Described anti-displacement formula stomach liver anastomosis bracket is in use, stomach liver anastomosis bracket is placed by ultrasonic gastroscope inserter on probation, liver's on-expansible end 4 is made to be in liver, stomach expansion end 3 is in stomach, film body 2 in the middle part of stomach expansion end 3 to rack body 1 is used for preventing bile and gastric juice from entering abdominal cavity, rack body 1 is not provided with film body 2 near liver's on-expansible end 4 side, adopts this half structure of film energy rigid support position in liver.
This utility model provides a kind of anti-displacement formula stomach liver anastomosis bracket; the method and the approach that implement this technical scheme are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
