Binding clip, binding clip seat, conduit, connecting rod and the handle being sequentially connected with；The binding clip includes two and half by the first hinge
Caliper, the rear ends of two half-calipers are hinged with pull bar, and the rear ends of two pull bars is by the second hinge, and described first
Bearing pin is installed on the front end of binding clip seat, and second bearing pin can slide back and forth along binding clip seat；The front end of the conduit takes the shape of the letter U, institute
State and chamber is in axial direction provided with connecting rod, and the chamber is connected with conduit；Being provided with conduit can be along conduit axial direction side
To mobile seal wire, the front end of the seal wire is connected with the second bearing pin, and the rear end of seal wire is stretched into the chamber of connecting rod, connection
Slidably connected on bar for controlling the movable sliding handle of seal wire.
Preferably, in axial direction it is provided with graduation mark on the needle guard.
Preferably, in axial direction it is provided with graduation mark on the conduit.
Preferably, the rear end of handle is in ring tab shape.
Further, the conduit is made up of niti-shaped memorial alloy, and seal wire is made up of stainless steel wire.
The utility model sets the cutting part that can widen biopsy specimen using the anterior U-shaped of biopsy nook closing member, passes through
Needle guard and supravasal graduation mark can control aspiration biopsy depth, and an open and close for binding clip are realized by sliding handle control seal wire
Close, each biopsy of pleura success rate can be improved, reduce tissue damage, mitigate patient suffering.

Embodiment
As shown in Fig. 1 ~ 5, a kind of biopsy of pleura device, including needle guard, needle point nook closing member and biopsy nook closing member, the needle guard is in flat
Sliding tubular, and the surface of needle guard is in axial direction provided with graduation mark, and the depth of the wall of the chest, the pin are entered available for recording needle set
Prong core and biopsy nook closing member are adapted with the internal diameter of needle guard, can be respectively placed in needle guard, coordinate needle guard to use；The needle guard
Other structures and needle point nook closing member structure it is identical with the structure of existing Pleura biopsy needle, therefore be no longer described in detail herein.Institute
State binding clip, binding clip seat 10, conduit 4, connecting rod 2 and handle 1 that biopsy nook closing member includes being sequentially connected with from front to back.The binding clip bag
Two half-calipers being hinged by the first bearing pin 6 are included, the half-caliper includes being used for the pincers valve 501 of biopsy sampling and for power transmission
Clamp handle 502, the rear end of two clamp handles 502 is hinged with pull bar 7, and the rear end of two pull bars 7 is cut with scissors by the second bearing pin 8
Connect；First bearing pin 6 is installed on the front end of binding clip seat 10, and second bearing pin 8 can slide back and forth along binding clip seat 10.It is described to lead
The front end of pipe 4 takes the shape of the letter U, and chamber is in axial direction provided with the connecting rod 2, and the chamber is connected with conduit 4；Conduit 4
It is interior provided with the seal wire 9 that can be moved along the axial direction of conduit 4, the front end of the seal wire 9 is connected with the second bearing pin 8, after seal wire 9
End is stretched into the chamber of connecting rod 2, is slidably connected in connecting rod 2 for controlling the movable sliding handle 3 of seal wire 9.The hand
The rear end of handle 1 is in ring tab shape, is easy to hold.
Wherein, the conduit 4 is made up of niti-shaped memorial alloy, and is in axial direction provided with graduation mark on conduit 4,
Biopsy nook closing member is placed in needle guard, the graduation mark of needle guard can be exposed by observing the rear portion of conduit 4, to calculate biopsy of pleura sampling
Depth；The seal wire 9 of conduit 4 is made up of stainless steel wire, by shifting sliding handle 3 onto, sliding handle 3 is slided along connecting rod 2, drives seal wire
9 move along conduit 4, so as to the second bearing pin of push/pull 8, due to the first bearing pin 6 and binding clip seat 10 can not occur it is relative slide so that
