Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of flexible transbronchial needle biopsy puncture needle,
Damage of the flexible reduction of needle body to endoscope, while guaranteeing the toughness of puncture needle.
It is a kind of flexible through bronchus needle technical solution adopted by the utility model to solve its technical problems is providing
Inhale biopsy needle, including needle body and syringe needle, the syringe needle is fixed on the front end of needle body, the needle body be by several pipe threads successively
Retaining ring connects the chain type pipe structure to be formed, and the both ends of the pipe thread are respectively internal buckle and outward buckle, and the internal buckle is tube wall varus
The first U-shaped latch closure for being formed, the first U-shaped latch closure opening are located inside pipe thread, and the outward buckle is that tube wall turns up the 2nd U to be formed
Type ring button, the second U-shaped latch closure opening are located at outside pipe thread, and the outward buckle of a pipe thread and another pipe thread is interior between adjacent pipe thread
Detain retaining ring connection.
The external annulus of the outward buckle pipe thread radially positioned at internal buckle internal ring wall and external annulus between, the internal buckle
Internal ring wall is between the radially internal ring wall and external annulus positioned at outward buckle of pipe thread.
Connection pipeline section between the internal buckle and outward buckle is conical pipe.
The depth of the distance between the taper tube wall and the first U-shaped latch closure opening less than the first U-shaped latch closure, the cone
The depth of the distance between shape tube wall and the second U-shaped latch closure opening less than the second U-shaped latch closure.
Connection between the conical pipe and internal buckle and outward buckle is smooth transition.
The pipe thread is stainless steel tube.
The long 0.55cm of the syringe needle, blade angle are 27 °, and the length of the needle body is 11.0cm.
Beneficial effect
In the present invention, the needle body of puncture needle is that successively retaining ring connects the chain type tube body formed by pipe thread, independent
Pipe thread is rigid structure, and the chain type tube body for connecting formation ensure that enough toughness on the whole, facilitates puncture procedure, adjacent tubes
There are certain distortion spaces between button, therefore the needle body has flexible on the whole, when Microendoscopic operates with,
The damage to endoscope can be reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged structure schematic diagram of the utility model needle body.
Fig. 3 is the structural schematic diagram of the utility model pipe thread.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
A kind of flexible transbronchial needle biopsy puncture needle as shown in Figs. 1-3, including needle body 1 and syringe needle 2, syringe needle
2 are fixed on the front end of needle body 1, and the long 0.55cm of syringe needle, blade angle are 27 °, and the length of needle body is 11.0cm.
Needle body 1 is that successively retaining ring connects the chain type pipe structure formed by several pipe threads 3, and pipe thread 3 is stainless steel tube rigidity
Structure.The both ends of pipe thread 3 are respectively internal buckle 301 and outward buckle 302, and internal buckle 301 is the first U-shaped latch closure that tube wall is inverted to form, the
One U-shaped latch closure opening 303 is located inside pipe thread 3, and outward buckle 302 is that tube wall turns up the U-shaped latch closure of to be formed second, the second U-shaped latch closure
Opening 304 is located at outside pipe thread 3.Connection pipeline section between internal buckle 301 and outward buckle 302 is conical pipe 305, conical pipe 305 with it is interior
Connection between button 301 and outward buckle 302 is smooth transition.
The outward buckle 302 of a pipe thread 3 is connect with 301 retaining ring of internal buckle of another pipe thread 3 between adjacent pipe thread 3.Outward buckle 302
External annulus pipe thread 3 radially positioned at internal buckle 301 internal ring wall and external annulus between, the internal ring wall of internal buckle 301 is in pipe thread 3
Radially positioned at outward buckle 302 internal ring wall and external annulus between, to prevent adjacent pipe thread 3 from falling off radially.Cone
The depth of the distance between 305 tube wall of shape pipe and the first U-shaped latch closure opening 303 less than the first U-shaped latch closure, 305 tube wall of conical pipe
The distance between second U-shaped latch closure opening 304 less than the second U-shaped latch closure depth, to prevent adjacent pipe thread 3 in the axial direction
It falls off, ensure that the stability of 1 structure of needle body.
The flexible transbronchial needle biopsy puncture needle is that successively retaining ring connects the chain type tube body formed by pipe thread 3,
Independent pipe thread 3 is rigid structure, and the chain type tube body for connecting formation ensure that enough toughness on the whole, and puncture is facilitated to grasp
