Abstract
The invention relates to a bile duct tumor biopsy sampling device which comprises a catheter. A control handle is connected to one end of the catheter, a side hole is formed in the side wall of a port at the other end of the catheter, an inner core is disposed in the catheter with one end extending into the control handle while the other end provided with a sampling unit in a winding manner, the control handle controls the inner core to rotate in the catheter and slides axially, the sampling unit is a sheet made of an elastic metal material, straight ports extending outwards are formed in the sampling unit or arc-shaped plane cutters are arranged on the sampling unit, the direction of cocking portions of the plane cutters is identical to the winding direction of the sampling unit, and the sampling unit is matched with the side hole and extends out or retracts in from the side hole through the control handle. The bile duct tumor biopsy sampling device has the advantages that tumor tissue on the wall of the bile duct is cut through the sampling with a blade to obtain tissue samples directly.
Description
Technical field
The invention belongs to tumor of bile duct tissue operation sampling device, particularly relate to a kind of tumor of bile duct biopsy extraction device.
Background technology
In the time of the ERCP of scope Wicresoft treatment cancer of biliary duct, need clear and definite whether cancer of biliary duct, existing method is to utilize the inspection of biliary tract cytology brush to carry out Immunohistochemistry, but the method positive rate is very low, cannot meet clinical needs.At present also do not find can be applicable to clinical tumor of bile duct biopsy extraction device.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tumor of bile duct biopsy extraction device, by the sampler with cutting edge, the tissue in bile duct wall is cut, and directly obtains tissue samples, whether can make a definite diagnosis cancer of biliary duct.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tumor of bile duct biopsy extraction device is provided, comprise conduit, described conduit one end connects joystick, on the sidewall of described conduit other end port, have a side opening, in described conduit, inner core is housed, described inner core one end is stretched in joystick, in conduit, rotate and slide axially by joystick control inner core, the described inner core other end is reeled sampler is installed, described sampler is the thin slice of being made up of elastic metallic material, on described sampler, have outside straight mouthful or arc planing tool, the direction of described planing tool perk part is consistent with sampler coiling direction, described sampler and side opening match and stretch out from side opening by joystick or retract.
The conduit of described side opening one side is provided with perspective witness marking.
Described side opening is 2 centimetres apart from conduit other end end face distance.
On described sampler, be evenly equipped with the planing tool of straight mouth or arc port.
Beneficial effect
The invention has the advantages that, by the sampler with cutting edge, the tumor tissues in bile duct wall is cut, directly obtain tumor tissues sample, whether can make a definite diagnosis cancer of biliary duct.
Brief description of the drawings
Structural representation when Fig. 1 is end of conduit sampler ejection of the present invention.
Fig. 2 is that end of conduit sampler of the present invention is wound on inner core contracting end view in the time of catheter interior.
Fig. 3 is the end view that end of conduit sampler of the present invention ejects state.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figures 1 to 3, a kind of tumor of bile duct biopsy extraction device, comprise conduit 1, described conduit 1 one end connects joystick, on the sidewall of described conduit 1 other end port, have a side opening 2, in described conduit 1, inner core 6 is housed, described inner core 6 one end are stretched in joystick, by joystick control inner core 6 in the interior rotation of conduit 1 and slide axially, described inner core 6 other ends are reeled sampler 3 are installed, described sampler 3 is thin slices of being made up of elastic metallic material, on described sampler 3, have outside straight mouthful or arc planing tool 4, the direction of described planing tool 4 perk parts is consistent with sampler 3 coiling directions, described sampler 3 matches and stretches out from side opening 2 by joystick or retract with side opening 2.
The conduit 1 of described side opening 2 one sides is provided with perspective witness marking 5.
Described side opening 2 is 2 centimetres apart from conduit 1 other end end face distance.
On described sampler 3, be evenly equipped with the planing tool 4 of straight mouth or arc port.
In actual use, patient inserts conduit 1 in bile duct, under perspective, witness marking 5 is placed in to suspicious lesions position in bile duct, joystick control inner core 6 slides axially in conduit 1, sampler 3 is moved to conduit 1 head end side opening 2 positions and rotates inner core 6 sampler 3 is ejected, then clockwise direction rotary guide pipe 1, the cutting edge 4 of sampler 3 above in rotary course cut bile duct wall, organizing after cut in bile duct wall enters conduit 1 through the through hole under cutting edge 4, in this way tumor tissues in bile duct be cut into strip and collect in the conduit 1 of hollow.Like this, just can get the tumor tissues of more amount, whether can make a definite diagnosis cancer of biliary duct.
