Abstract
The invention provides an anti-shifting stomach and liver anastomosis stent which comprises a stent body. One end of the stent body is provided with a stomach expanding end and extends to the stomach, and the other end of the stent body is provided with a liver non-expanding end and extends to the liver. A membrane body is arranged on the surface of one side of the stent body close to the stomach expanding end. The surface of one side of the stent body close to the liver non-expanding end is smooth and free of attachments. The stomach expanding end of the stent body is of an expanded structure extending outwards in the radial direction of the stent body to form a ring-shaped flange, so that the stent can be placed stably and reliably and is prevented from being shifted towards the liver. The anti-shifting stomach and liver anastomosis stent is of a half covering membrane structure, i.e., the membrane body is arranged on the surface of one side of the stent body close to the stomach expanding end, and the surface of one side of the stent body close to the liver non-expanding end is not provided with a membrane body. The stent can be prevented effectively from being shifted towards the stomach and can also be prevented effectively from being shifted towards the liver, and the position of the stent is stabilized.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of anti-moving type stomach liver anastomosis bracket.
Background technology
Obstructive jaundice is common clinical, and its main cause comprises calculus of bile duct, bile duct injury, cancer of biliary duct, cancer of pancreas, hepatocarcinoma, duodenal carcinoma, metastatic carcinoma, chronic pancreatitis and parasite etc.Releasing is blocked to Main Means comprises operation, percutaneous to drive in the wrong direction bile duct (ERCP) drainage through liver puncture drain (PTCD) and through duodenoscope.Operative treatment wound and risk are all comparatively large, for the patient that primary affection cannot excise, generally do not consider that using the mode of operation to remove blocks.PTCD is easy and simple to handle, is easy to be accepted by patient, 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.When there is the complication such as ascites as patient, external drainage treatment is taboo.Current research proves, the inner drainage treatment through human body natural's path is a kind of method being more suitable for Preserving time drainage system, and therefore ERCP just progressively becomes the first-selected therapeutic modality removing obstructive jaundice at present.For experienced scope doctor ERCP intubate is that mortality can reach 3%-5%.When patient there is topography variation, operation change gastrointestinal tract structure, duodenum or stenosis of bile duct time, mortality will be higher.When patient after intubation defeat is again by face PTCD or surgical operation drain.
Over nearly 5 years, metal rack starts to be applied to puncture drainage between digestive tract and biliary tract, treatment malignant obstructive jaundice.Another kind except ERCP is efficient, the inner drainage treatment mode of Wicresoft to make this technology be expected to become.And the metal rack be not still applicable at present coincide for stomach liver, the incidence rate of conventional stent displacement is high.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of anti-moving type stomach liver anastomosis bracket.
In order to solve the problems of the technologies described above, the invention provides a kind of anti-moving type stomach liver anastomosis bracket, comprising: rack body, one end of rack body has stomach expansion end, extends to stomach, and 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 the surface near the side of stomach expansion end.
Further, described rack body near the side smooth surface of liver's on-expansible end without attachment.
Further, described anti-moving type stomach liver anastomosis bracket is metal material.
Beneficial effect:
1, the stomach expansion end of rack body of the present invention is the expansion structure of the annular flange that extends radially outwardly out along rack body, stentplacement can be made reliable and stable, prevent to liver internal shift.
2, the present invention's anti-moving type stomach liver anastomosis bracket adopts half structure of film, namely rack body arranges film body on the surface near the side of stomach expansion end, and rack body does not arrange film body near a side surface of liver's on-expansible end, can support be effectively prevented to be shifted to gastric, also can effectively prevent support to liver internal shift, center rest position.
3, the present invention's anti-moving type stomach liver anastomosis bracket can reduce patient's misery in malignant biliary obstruction treatment, extends patient's life span.
4, the present invention's anti-moving type stomach liver anastomosis bracket applied range, easy to operate.
5, the present invention's anti-moving type stomach liver anastomosis bracket structure is simple, easily manufactured, and one-shot forming, can realize large-scale industrial production, cost is lower.
Accompanying drawing explanation
To do the present invention below in conjunction with the drawings and specific embodiments and further illustrate, above-mentioned or otherwise advantage of the present invention will become apparent.
Fig. 1 is the anti-moving type stomach liver anastomosis bracket structural representation of the embodiment of the present invention, wherein, and 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, the present invention is elaborated.
As shown in Figure 1, a kind of anti-moving type stomach liver anastomosis bracket, comprising: 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.
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 the surface near the side of stomach expansion end 3, for preventing the support in liver from coming off and being shifted, and center rest position.Rack body 1 near the side smooth surface of liver's on-expansible end 4 without attachment.Film body 2 is silica gel material, for preventing the liquid spill flowing through support, prevents support surrounding tissue from wrapping up network structure and cannot reclaim simultaneously.
Described anti-moving type stomach liver anastomosis bracket in use, try out inserter by ultrasonic gastroscope and place stomach liver anastomosis bracket, 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 enters abdominal cavity for preventing bile and gastric juice, rack body 1 is not provided with film body 2 near liver's on-expansible end 4 side, adopts this half position of structure of film energy rigid support in liver.
Described anti-moving type stomach liver anastomosis bracket is metal material.
The invention provides a kind of anti-moving type stomach liver anastomosis bracket; the method and access of this technical scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
