Pipe.
Beneficial effects of the present invention take stone without needing to cut choledochus as usual, stay postoperative choledochus needs
The bile of T Tube Drain for a period of time is set, but by incision cystic duct, then carry out taking stone, since cystic duct is thinner, need to be put into
Support ring can just prop up cystic duct, then display mirror and holding forceps are extend into cystic duct, and calculus is taken out.Due to first
Optical fiber and the second optical fiber carried out shading treatment, so two optical fiber settings are also mutually unaffected in the same connecting tube, the
External optical transport to the optical fiber on mirror ring, can be played the role of illumination when display mirror is in cystic duct, helped by one optical fiber
The position of doctor's searching calculus；Second optical fiber, can be by the picture that captures mirror surface due to the illuminating effect of the first optical fiber
It is transferred on the eyepiece on outside, to the situation inside physician feedback cystic duct；Support ring, the second conduit and the first conduit
Material is silica gel, and the first fixed ring is equipped with inside support ring, connecting rod is equipped in the first conduit, one is played when support ring protrudes into
The effect of fixed fixation, also facilitates and support ring is protruded into and taken out.Support ring is communicated with the first conduit, is inflated when to the first conduit
When, gas leads to support ring simultaneously, and gall-bladder tube stay is big, facilitate insertion display mirror and holding forceps, takes out calculus.
First using methyl ethylene silica gel as base-material, preliminary packet roller is carried out, white carbon black is added after spreading out as enhancing
Agent, Lai Zengqiang integral material intensity, while octamethylcyclotetrasilazane, hexamethyl cyclotrisilazane, trivinyl front three is added
Base cyclotrisilazane, 1,3-, bis--n-propyl -1,1,3,3- tetramethyl-disilazanes, dimethyl silicone polymer changing as a whole
Property agent, to change the intensity of 2- methyl ethylene silica gel, so as to reduce Compression Set intensity, especially only have
In octamethylcyclotetrasilazane, hexamethyl cyclotrisilazane, trivinyl trimethyl cyclotrisilazane, 1,3-, bis--n-propyl-
1,1,3,3- tetramethyl-disilazane, dimethyl silicone polymer according to aforementioned proportion carry out compounding be that can reach best effect
Fruit.Pass through octamethylcyclotetrasilazane, hexamethyl cyclotrisilazane, trivinyl trimethyl cyclotrisilazane, 1,3- bis--simultaneously
N-propyl -1,1, the group having on 3,3- tetramethyl-disilazanes, dimethyl silicone polymer, can be effectively improved 2- methyl
The intensity of vinyl silica gel is particular enable to resist the erosion of bile, operation in gallbladder is suitble to use in gallbladder operation.
Meanwhile mixing glue is divided into component A and B component, one can be played and mix catalyst chloroplatinic acid one step ahead
The effect of conjunction carries out that better mixed effect can be played in mixed process in later period component A and B component.
The viscosity of component A and B component can be adjusted in later period addition isopropanol, acetylene alcohol, prevents its from coking, L- benzene occurs
Ala amide, nervonic acid amide are smooth dose well, enable to Silica Surface to have preferable smoothness after addition, subtract
Lack tissue and blood in surgical procedure to be adhered to above.
