Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of percutaneous and gets involved special sheath pipe box part through transhepatic cholangiography.
Background technology:
Percutaneous transhepatic puncture cholangiography (percutaneoustranshepaticcholangiography, PTC): refer to the puncture needle or the thin puncture needle of Chiba that use band plastic tube epitheca, from right midaxillary line or front side pathway, under x-ray tv or B-mode ultrasonic apparatus monitor guiding, puncture into stones in intrahepatic bile duct, the contrast agent that reinjects gets final product clear display extrahepatic duct, can understand diseased region in bile duct, degree and scope, contribute to the discriminating of jaundice.Be mainly used in patients with obstructive jaundice, to understand obstruction of biliary tract position, scope and reason.
Biliary tract intervene operation is based on above-mentioned percutaneous transhepatic puncture cholangiography (PTC), according to different therapeutic modalities, develops further again and PTCD (percutaneous transhepatic cholangiography and drainage) art, biliary tract rack implantation etc.
Existing radiography sheath pipe is mostly relatively short, only has front hole, when to cholangiography, will distinguish radiography, with the situation of lesions showed to far-end and near-end; Sometimes contrast medium loss is very fast, diseased region can be caused to show and owe clear, the situations such as measurement Numerical accuracy is not good enough.
Utility model content:
Short for radiography sheath pipe in above-mentioned prior art, and only have a front hole, during radiography, the dispersion force of simple stomidium becomes point-like, operating time is long, opereating specification is limited, and cause display to owe clear, the defect such as accurate owed by measured value, it is simple that the purpose of this utility model is to provide a kind of structure, easy and simple to handle, during radiography, wide, the speed of Spread scope is fast, and the good percutaneous of display effect gets involved special sheath pipe box part through transhepatic cholangiography.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of percutaneous gets involved special sheath pipe box part through transhepatic cholangiography, comprises catheter sheath, it is characterized in that: convergent divergent channel is set in catheter sheath, and catheter sheath is removably connected with convergent divergent channel; Described catheter sheath comprises the sheath handle of rear end and the sheath pipe of front end, is provided with multiple side opening in the front end of sheath pipe, and sheath handle is provided with the manifold be communicated with sheath pipe, and manifold end is connected with three-way valve, in sheath handle, be provided with haemostatic valve; Described convergent divergent channel comprises the tip of the handle of rear end, the body at middle part and front end; Convergent divergent channel is inserted in catheter sheath by haemostatic valve, and when the two has assembled, the tip of convergent divergent channel just stretches out outside catheter sheath.
Further setting of the present utility model is:
Described sheath length of tube is set to 30cm.
Described side opening quantity is at least 3, is evenly arranged on the long tube wall in sheath pipe front end 1/3.
Preferably, described side opening quantity arranges 20, is evenly arranged in the both sides of sheath pipe front end tube wall.
The beneficial effects of the utility model: this utility model is by doing length by sheath pipe, long sheath can cover whole biliary system substantially, and offer multiple side opening in sheath pipe front end, the distance that arranges of side opening reaches certain length, injection disposablely can complete the radiography of near-end and far-end, the speed of disperse is fast, the scope of disperse is wide, be conducive to measuring lesion region more accurately, and sheath pipe can be convenient for changing the intervention such as conduit, inner support delivery system equipment, simultaneously can the reducing time, reduce the amount of radiation that patient and doctor accept in art.
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, this utility model to be described in further detail.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model embodiment split;
Fig. 2 is the structural representation of this utility model embodiment zoarium.
Detailed description of the invention:
Shown in Fig. 1, Fig. 2, a kind of percutaneous of the present utility model gets involved special sheath pipe box part through transhepatic cholangiography, comprise catheter sheath 1, convergent divergent channel 2 is set in catheter sheath 1, and catheter sheath 1 is removably connected with convergent divergent channel 2, and described catheter sheath 1 comprises the sheath pipe 11 of front end and the sheath handle 12 of rear end, multiple side opening 16 is provided with in the front end of sheath pipe 11, sheath handle 12 is provided with the manifold 13 be communicated with sheath pipe 11, and manifold 13 end is connected with three-way valve 14, is provided with haemostatic valve 15 in sheath handle 12; Described convergent divergent channel 2 comprises the tip 23 of the handle 21 of rear end, the body 22 at middle part and front end, convergent divergent channel 2 inserts in catheter sheath 1 by haemostatic valve 15, when the two has assembled, the tip 23 of convergent divergent channel 2 has just stretched out outside catheter sheath 1, forms percutaneous and gets involved special sheath pipe box part through transhepatic cholangiography.
In the present embodiment, described sheath pipe 11 length is set to 30cm, and longer sheath pipe 11 length can cover whole biliary system substantially, is more conducive to carrying out of biliary tract intervene operation.
In the present embodiment, described side opening 16 quantity is at least 3, is evenly arranged on the long tube wall in sheath pipe 11 front end 1/3; As shown in Figure 2, preferably, described side opening 16 quantity arranges 20, in the tube wall left and right sides, sheath pipe 11 front end, 10 side openings 16 are set respectively, the side opening 16 of dense distribution, and be evenly arranged in the both sides of sheath pipe 11 front end tube wall, and can synchronously to pathological changes distance end radiography, the length enabling pathological changes narrow, degree show sooner, more accurately.
By convergent divergent channel 2 and catheter sheath 1 external member with the use of, during injection, disposablely can complete the radiography of pathological changes near-end and far-end, the speed of contrast medium disperse is fast, and the scope of disperse is wide, enables the length of diseased region, degree shows sooner, more accurately, be conducive to measuring lesion region more accurately, and catheter sheath 1 can be convenient for changing conduit, inner support delivery system etc. and gets involved equipment, simultaneously can the reducing time, reduce the amount of radiation that patient and doctor accept in art.
The above; be only preferred embodiment of the present utility model; not in order to limit this utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
