Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of disposable fast single-hand biopsy gun.
Background technology
We know, biopsy is the conventional diagnosis and treatment means of hospital's Medicine and Surgery, generally to complete sampling by puncture, used tool is mainly various puncture needles or cell taking gun, rifle formula movable detecting apparatus have sampling rapidly, damage feature little, convenient operation, but cell taking gun is mainly by overseas-built at present, and cell taking gun is complex structure mostly, expensive, need bimanualness to complete, use inconvenient.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of disposable fast single-hand biopsy gun is provided, and adopts the design of rifle body formula, low cost of manufacture, and operation sampling is convenient.
This utility model is achieved through the following technical solutions: a kind of disposable fast single-hand biopsy gun, comprise rifle body, the front end muzzle of the bore of described rifle body upper end is provided with needle body holder, the rear end of bore is provided with installing hole, wherein said needle body holder is installed fixing puncture needle, described installing hole is used for installing needle tubing, and described needle tubing front end face leans with the shifting part that is arranged on bore two side, and described bore two side is provided with the turn Fastener that withstands syringe rear end face.
Further, in described needle tubing, be provided with piston, described piston connects piston rod, and the bar head of described piston rod is positioned at the outside of installing hole.
Further, the trigger of described rifle body is connected with piston rod, and described trigger one side is provided with safety lock.
Further, described bore both sides are provided with sliding tray, and described shifting part is arranged in sliding tray, and described shifting part slides by stirring along sliding tray.
Further, described needle body holder is by preventing the axially movable fixed cover I of puncture needle and preventing that fixed cover II two parts that puncture needle radially wobbles from connecting to form.
Compared with prior art, the beneficial effects of the utility model are: this utility model adopts rifle body that needle tubing and fixing needle body are installed, the bore rear end of rifle body upper end is provided with the installing hole that needle tubing is installed, bore both sides are provided with shifting part and the turn Fastener of fixing needle tubing, puncture needle is installed fixing by the needle body holder of bore front end, the trigger of rifle body is connected with the piston rod in needle tubing, only needs singlehanded cocking just can carry out sampling operation, low cost of manufacture, operation sampling is convenient.
Accompanying drawing explanation
