Abstract
This utility model is a kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assemblies, comprise gastroscope, sphincterotomy cutter, seal wire, biopsy forceps, fixed mount, described fixed mount is a sleeve pipe, described sleeve pipe is provided with gap, and its side is provided with bullport, described seal wire can insert the bullport of described fixed mount, and can be free to slide.By the guiding of lead-in wire to biopsy forceps, accurately biopsy forceps is sent into focus, biopsy sampling is carried out to pathological tissues.Can accurately position seal wire by sphincterotomy cutter and contrast imaging technology and adjust.Design is light and handy, convenient operation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, refers in particular to a kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assembly.
Background technology
Biopsy forceps is that endoscopy gets the indispensable instrument of Pathologic specimen, also right and wrong a kind of medical examination means usually in endoscopy, and what developed is very ripe, it is the affected area being entered human body by endoscope in daily work, the tissue of pathological changes is sampled, then by judging a kind of method of the state of an illness to the detection of pathological tissues.
Biliary tract retrograde urography (ERC) technology is widely used in clinical; But, in clinical practice for many years, wish to carry out biopsy sampling by endoscope to biliary tract, even gallbladder always, long and narrow due to bile duct and the biopsy forceps pliability of endoscope is inadequate, be difficult to reach focus by bile duct, pathological tissues accurately located and samples; In order to achieve the above object, needing one badly can accurately locate, and enters bile duct smoothly, and carries out the Novel biliary tract biopsy forceps instrument of living body sampling to focus.
Summary of the invention
The purpose of this utility model is to provide kind of an a kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assembly, and solving existing biopsy forceps cannot smoothly by bile duct, to the problem that pathological tissues is accurately located and sampled.
This utility model adopts following technical scheme:
A kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assembly, comprise endoscope (1), sphincterotomy cutter (2), seal wire (3), biopsy forceps (4), fixed mount (5), described fixed mount (5) is a sleeve pipe, described sleeve pipe is provided with gap (51), and be provided with in its side along the axially through bullport (52) of sleeve pipe, described seal wire (3) inserts the bullport (52) of described fixed mount and is free to slide.
The internal surface of sleeve pipe of described fixed mount (5) clamps conduit (41) outer wall of described biopsy forceps, and described fixed mount (5) length is 1 centimetre.
After the conduit (41) of described biopsy forceps (4) is sandwiched into described fixed mount (5), insert in endoscope (1) under entering the described seal wire (3) in endoscope (1) and guiding.
Advantage of the present utility model is as follows:
1. by the guiding of seal wire to biopsy forceps, accurately biopsy forceps is sent into bile duct inner disease foci, biopsy sampling is carried out to pathological tissues.
2. can accurately position seal wire by sphincterotomy cutter and contrast imaging technology and adjust.
3. design is light and handy, convenient operation.
Accompanying drawing illustrates:
Fig. 1 is this utility model external member first work process view;
Fig. 2 is this utility model external member second work process view;
Fig. 3 is this utility model external member fixed mount schematic diagram;
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Following examples are only for this utility model example is clearly described, and the restriction not to embodiment of the present utility model.For those of ordinary skill in the field; can also make other multi-form change or variations on the basis of the following description, and these belong to this utility model spirit apparent change of drawing or variation is still among protection domain of the present utility model.
According to Fig. 1-3; A kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assembly, comprise endoscope 1, sphincterotomy cutter 2, seal wire 3, biopsy forceps 4, fixed mount 5, it is characterized in that: described fixed mount 5 is a sleeve pipe, described sleeve pipe is provided with gap 51, and be provided with in its side along the axially through bullport 52 of sleeve pipe, described lead-in wire 3 inserts the bullport 52 of described fixed mount and is free to slide.The internal surface of sleeve pipe of described fixed mount 5 clamps conduit 41 outer wall of described biopsy forceps, and described fixed mount 5 length is 1 centimetre.
A kind of Transhepatic Cholangiobiopsy in Malignant Obstructive Jaundice pincers assembly according to claim 2, is characterized in that: after the conduit 41 of described biopsy forceps (4) is sandwiched into described fixed mount 5, insert in endoscope 1 under entering the described lead-in wire 3 in endoscope 1 and guiding.
Specific operation process is as follows:
First work process: first endoscope 1 enters human body, seal wire 3 enters human body by endoscope 1 under the help of sphincterotomy cutter 2, go between 3 front end flexible elongated, adjusted by the direction of sphincterotomy cutter 2 pairs of seal wires 3 and angle, under the help of contrast imaging technology, seal wire is sent into affected area by bile duct.
Second work process: described sphincterotomy cutter 2 is detached, only described lead-in wire 3 is stayed in the body, the conduit 41 of described biopsy forceps 4 is sandwiched by the gap 51 of described fixed mount, so described fixed mount 5 cannot be free to slide on the seal wire 41 of biopsy forceps, but the distance between described fixed mount 5 and the binding clip of described biopsy forceps 4 can be adjusted by external force.Then by the bullport 52 on described fixed mount, biopsy forceps is sent into focus by seal wire 3, pathological tissues is sampled.
Claims (3)
