Abstract
The invention belongs to the field of medical instruments and particularly relates to a percutaneous transhepatic puncture choledochoscope which comprises a puncture choledochoscope body and a sheath. The puncture choledochoscope body comprises a needle-like rigid operating end, an operating part, a light source connector, an image output end, and a drainage passage, wherein the needle-like rigid operating end, the operating part, the light source connector and the image output end are mutually communicated, and the drainage passage is used for drainage. The sheath comprises a rigid sheath end, a water inlet passage and a water outlet passage. The rigid sheath end is disposed outside the needle-like rigid operating end. The front end of the needle-like rigid operating end is provided with an optical lens and a fiber-optic output end. The percutaneous transhepatic puncture choledochoscope has the advantage of the puncture needle that the puncture needle can puncture skin and tissue to enter a human body and the advantage that the endoscope provides doctors with inside images, a doctor directly watches a monitor to operate with no need of aimless operation relying on experiences and judgments when puncturing with the percutaneous transhepatic puncture choledochoscope, and surgical safety is improved.
Description
Technical field
The invention belongs to field of medical appliances, specifically is that percutaneous is through the liver puncture choledochoscope.
Background technology
Puncture needle comprises the pin heart and needle stand, has scale, and it belongs to the interventional radiology equipment, and in the interventional radiology operation, skin puncture enters in the body with further guiding interventional radiology equipment.Present puncture needle is divided into: single wall puncture needle, the two parts trocars, the three parts trocars, atrial septal puncture pin 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 bile duct puncture device, and described bile duct puncture 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, is provided with the side opening that is communicated with rear interior cavity in the front end side wall of expansion tube.This bile duct puncture 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 in puncture needle, arranges, can monitor when solving lancet puncture that the percutaneous of problem of puncture situation is extremely urgent through the liver puncture choledochoscope.
Summary of the invention
Technical purpose of the present invention 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 when finishing puncture, also can obtain image simultaneously, make the user have better experience.
In order to reach above-mentioned technical purpose, the present invention realizes by following technical scheme:
A kind of percutaneous of the present invention 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 places 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 the present invention, 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 the pin taper that has the inclined-plane, and described optical lens and fiber-optic output place 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.
In the present invention, the diameter of described optical lens is more than or equal to 1.0mm, and its transmission system is fibre light guide system or glass optical system.
In the present invention, described operating portion comprises pressing close to the assurance part of staff, and described drainage channel places on the operating portion.
In addition, for the ease of using, described intake tunnel and exhalant canal axially stretch out respectively to the left and right along the sheath pipe.
Compared with prior art, the invention has the beneficial effects as follows:
Percutaneous of the present invention is through the liver puncture choledochoscope, combining puncture needle can skin puncture and the tissue advantage that enters human body, and endoscope can provide the advantage of doctor's internal view picture, the doctor is by using percutaneous when the liver puncture choledochoscope punctures, no longer rely on experience and judgement, have necessarily and carry out blindly, but under the direct-view of monitor, operate, improved the safety of operation.
