Abstract
The utility model belongs to the field of medical equipment, and particularly relates to a percutaneous transhepatic puncture choledochoscope. The percutaneous transhepatic puncture choledochoscope comprises a puncture choledochoscope body and a sheath catheter. The puncture choledochoscope body comprises a needle-shaped hard operation end portion, an operation portion, a light source connector, an image output end and a drainage channel used for drainage, wherein the needle-shaped hard operation end portion, the operation portion, the light source connector, the image output end and the drainage channel are mutually communicated. The sheath catheter comprises a hard sheath catheter end portion, a water inlet channel and a water outlet channel. The hard sheath catheter end portion is placed on the periphery of the needle-shaped hard operation end portion and the front end portion of the needle-shaped hard operation end portion is provided with an optical lens and an optical fiber output end. According to the percutaneous transhepatic puncture choledochoscope, the advantage that a puncture needle can puncture the skin and the tissue to enter the human body and the advantage that an endoscope can provides inside view images for a doctor are combined, so that when the percutaneous transhepatic puncture choledochoscope is used for puncturing by the doctor, the phenomenon that puncture is blindly conducted only depending on the experience and the judgment of the doctor is avoided and puncture is conducted under the direct view of a monitor, and therefore the safety of an operation is improved.
Description
Technical field
This utility model belongs to field of medical appliances, and specifically percutaneous is through the liver puncture choledochoscope.
Background technology
Puncture needle, comprise the pin heart and needle stand, and with scale, it belongs to the interventional radiology equipment, and in the interventional radiology operation, skin puncture, enter in body further to guide the interventional radiology equipment.Present puncture needle is divided into: single wall puncture needle, the two parts trocars, the three parts trocars, Interaurcular septum puncture needle and peeling puncture needle.
In addition, someone has also developed a kind of patent No. is 201020129258.9, notification number is CN201759972U, name is called the patent of biliary tract puncturing device, and described biliary tract puncturing device comprises micro-wire, convergent divergent channel, and this convergent divergent channel comprises the inner chamber before and after running through, described convergent divergent channel is coaxial toughness side opening convergent divergent channel, described inner chamber is divided into forward and backward inner chamber, and the diameter of front interior cavity and micro-wire match and merge less than rear interior cavity, in the front end side wall of expansion tube, is provided with the side opening that is communicated with rear interior cavity.This biliary tract puncturing device can reduce the program of puncture operation technique, reduce patient's misery and risk, reduced operating time, and the situation of the biliary tract of radiography understanding in real time, but this puncture needle is when reality is used, still need to rely on doctor's judgement and experience to carry out for the puncture puncture position, have certain risk.Therefore, research and develop a kind of endoscope that arranges in puncture needle, can monitor when solving lancet puncture that the percutaneous of problem of puncture situation is extremely urgent through the liver puncture choledochoscope.
The utility model content
Technical purpose of the present utility model is to overcome the deficiencies in the prior art, provide a kind of percutaneous through the liver puncture choledochoscope, this percutaneous through the liver puncture choledochoscope effectively in conjunction with puncture needle advantage and endoscope's function, make the user also can obtain simultaneously image when completing puncture, make the user have better experience.
In order to reach above-mentioned technical purpose, this utility model is realized by following technical scheme:
A kind of percutaneous described in the utility model is through the liver puncture choledochoscope, comprise puncture mirror main body and sheath pipe, described puncture mirror main body comprises needle-like hard work end, operating portion, light source joint, the output end of image that is interconnected and the drainage channel that is used for drain, described sheath pipe comprises hard sheath tube end and intake tunnel and exhalant canal, described hard sheath tube end is placed in the periphery of needle-like hard work end, and the leading section of described needle-like hard work end is provided with optical lens and fiber-optic output.
In this utility model, the maximum gauge 6mm of described needle-like hard work end.
As the further improvement of above-mentioned technology, the leading section of described needle-like hard work end is for being with bevelled pin taper, and described optical lens and fiber-optic output are placed in the incline position of this pin taper, this pin taper length 20mm.
For better protective action is provided, the front end inclined-plane of described optical lens and fiber-optic output is provided with cover plate.
