Abstract
The utility model relates to the field of medical equipment, especially, relate to a stalk huang leads to dedicated biliary tract support of animal models again. It includes interior sleeve pipe of support and support outer tube, in the support sleeve pipe one end be opening, the other end be coniform and remain silent the structure and the outer wall threaded, support outer tube one end be opening, the other end for cylindric structure and the inner wall of remaining silent threaded, the drum surface of the cylindric structure of remaining silent adopts plastic film to make, there is the protruding shear fracture that just is that is the circumference and describes the distribution outside the open end of interior sleeve pipe of support and outer tube, is convenient for to increase contact and frictional force with the bile duct, is difficult for the slippage, easily puts into in the bile duct. The utility model has the advantages of simple structure, can avoid frictional force undersize between bile duct and the inside and outside sleeve pipe of biliary tract support well and the shortcoming of easy slippage, be convenient for block the switch -on of animal bile duct and secondary and be difficult for the weeping, have low cost, convenient to use's characteristics.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of Huang that obstructs and leads to the special biliary tract rack of animal model again.
Background technology
Obstructive jaundice is one of common disease of the mankind, and obstructive jaundice is the jaundice caused by extrahepatic bile ducts or stones in intrahepatic bile duct block, and the former is called extrahepatic cholestatic jaundice; The latter is called liver internal congestion jaundice.
In order to study the mechanism of correlated pathophysiologic or the effect such as medicine, surgical intervention further, usually adopting animal to simulate obstructive jaundice and then carrying out the experimentation of being correlated with.The method adopted be mostly first in animal body to its BDL from disconnected to cause obstructive jaundice, then the bile duct blocked and bile duct or bile duct and intestinal lead to by the second phase more again, suture is adopted to coincide when leading to more difficult again, so usually use biliary tract rack to carry out bridge joint in this process, make to lead to operation again and become easier.But, the finished product of this type of biliary tract rack is not had in currently available technology, preoperative needs adopts common drainage tube to prune, and the smooth easy slippage of its tube wall of drainage tube of pruning, and due to second operation abdominal adhesions, be separated relevant bile duct intestinal tube again Stent Implantation obviously can increase operating difficulty, extend operating time, and easily hemorrhage, cause various inconvenience.
In sum, in actual production, lack a kind of convenience block bile duct, be easy to connect, facilitate the yellow biliary tract rack that logical animal model is special again of the stalk of operation technique, reduction operating difficulty.
Summary of the invention
The technical problems to be solved in the utility model how to overcome the deficiencies in the prior art, provide a kind of convenience to block bile duct, be easy to connect, can not leakage, not easily slippage, facilitate operation technique, reduce the yellow biliary tract rack that logical animal model is special again of the stalk of operating difficulty.
The technical scheme that this utility model adopts for achieving the above object is: a kind of Huang that obstructs leads to the special biliary tract rack of animal model again, comprise support inner sleeve and support trocar sheath, described support inner sleeve one end is opening, the other end is coniform closed configuration and outer wall has helicitic texture, described support trocar sheath one end is opening, the other end is cylindric closed configuration and inwall has helicitic texture, the drum surface of described cylindric closed configuration adopts plastic sheeting manufacture, there is the projection of circumferentially shape distribution outside the opening of described support inner sleeve and support trocar sheath and be shear fracture.
Further: have outside the opening of described support inner sleeve and support trocar sheath two circumferentially shape distribution projection.
The utility model has the advantage of conveniently block bile duct, be easy to connect, can not leakage, not easily slippage, facilitate operation technique, reduce operating difficulty.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Detailed description of the invention
Embodiment 1:
A kind of Huang that obstructs leads to the special biliary tract rack of animal model again; comprise support inner sleeve 1 and support trocar sheath 2; described support inner sleeve 1 one end is opening, the other end is coniform closed configuration 3 and outer wall has helicitic texture 6; described support trocar sheath one end is opening, the other end is cylindric closed configuration 4 and inwall has helicitic texture 7; the drum surface of described cylindric closed configuration 4 adopts plastic sheeting manufacture, has the projection 5 of circumferentially shape distribution and be shear fracture outside the opening of described support inner sleeve 1 and support trocar sheath 2.During use, the bile duct of animal and bile duct or bile duct and intestinal tube are disconnected, support inner sleeve is inserted respectively in the fracture of two ends, support trocar sheath, and by support inner sleeve, projection outside support trocar sheath opening is fixed, shear fracture is easy to insert in bile duct, in time needing the bile duct of animal and bile duct or bile duct and intestinal tube again to connect, only the tip surgical scissors of the coniform closed configuration of support inner sleeve need be cut off sub-fraction, again with the plastic sheeting of the cylindric closed configuration of the nubbin stamp overdraw frame trocar sheath of the coniform closed configuration of support inner sleeve, support inner sleeve is threadingly inserted in support trocar sheath, the bile duct of animal and bile duct or bile duct and intestinal tube can be made to recover UNICOM, and have can not leakage, slippage can not be easy to the advantage of again separating, .
Embodiment 2:
Have outside the opening of described support inner sleeve 1 and support trocar sheath 2 two circumferentially shape distribution projection 5, remainder is identical with embodiment 1.
Above-described embodiment, just in order to technical conceive of the present utility model and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.The change of every equivalence done by the essence of this utility model content or modification, all should be encompassed in protection domain of the present utility model.
