Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
As Fig. 1, the present invention includes nook closing member joint 1, conduit mount 2, pin adjustable pipe 3, proximal lock gripping members 4, go out pin regulating handle 5, go out pin and regulate lock 6, handle 7, remote lock gripping members 8, outer tube adjustable pipe 9, pin 10 and outer tube 11, wherein pin 10 is connected on nook closing member joint 1, nook closing member joint 1 is provided with conduit mount 2 successively to the far-end of pin 10, pin adjustable pipe 3, proximal lock gripping members 4, go out pin regulating handle 5, go out pin and regulate lock 6, handle 7, remote lock gripping members 8 and outer tube adjustable pipe 9, wherein nook closing member joint 1 and conduit mount 2 are threaded connection, conduit mount 2 and pin adjustable pipe 3 are threaded connection, nook closing member joint 1, proximal lock gripping members 4, go out pin and regulate that to be equipped with perpendicular to direction of rotation outside lock 6 and remote lock gripping members 8 convex stupefied, be convenient to rotate.
As Fig. 2, go out pin and regulate lock 6 to comprise directed cavity 12, directed cavity 12 is provided with screens groove 13, and screens groove 13 is symmetricly set on directed cavity both sides, and screens groove 13 is L-type groove, and comprise axial gathering sill 14 and radial lock groove 15, lock groove 15 is at the far-end of gathering sill 14.
As Fig. 3, go out in pin regulating handle 5 position blocking pin 16 be provided with going out pin and regulate screens groove 13 adaptation on lock 6, position blocking pin 16 can slide along gathering sill 14, and position blocking pin 16 may be stuck on lock groove 15.
As Fig. 4, go out pin regulating handle 5 inner spring 17 uncompressed, for spring goes out pin mode, position blocking pin 16 is positioned at gathering sill 14, go out pin regulating handle 5 and promote out pin under external force, after external force release, go out pin regulating handle 5 proximally withdraw of the needle automatically under compression spring 17 acts on.
As Fig. 5, go out pin regulating handle 5 inner spring 17 and compress, for manually going out pin mode, position blocking pin 16 is positioned at lock groove 15, goes out pin regulating handle 5 and go out pin to regulate lock 6 to be fixedly connected as entirety.
The present invention in use, operation consent, doctor can first according to self situation and different Curing circumstance select optimal go out pin mode.Select spring when going out needle mould formula, guarantee that position blocking pin 16 is positioned at gathering sill 14, then spring is in free state, can discharge by pressing pin regulating handle 5, and the position blocking pin 16 going out pin regulating handle, going out pin and regulate in the gathering sill of lock 6 to slide, realizes spring and goes out pin.Select when manually going out pin, then will go out pin and regulate lock 6 proximally move and rotate, and make position blocking pin 16 be positioned at lock groove 15, then can go out pin and regulate lock 6 and go out pin regulating handle 5 and be fastenedly connected and be integrated also locking spring thus realize Non-follow control and go out pin.
After selecting out pin mode, prepare vacuum injector (not shown), after syringe shifts the end onto, syringe is in without gaseity.Three-way valve (not shown) is threaded to OFF position, syringe piston of pulling back, until subscribe position.
By near-end locking member 4 with go out pin regulating handle 5 and move to near-end of the present invention locking, pin is regained in outer tube 11 completely.
Holding position, inserts endoscopic biopsy duct by the present invention, Handleset and scope are fixed by spun outer tube adjustable pipe 9.
Unclamp remote lock gripping members 8, sliding handle 7 makes outer tube 11 far-end arrive ideal position and lock remote lock gripping members 8, and this step is the length regulating outer tube to stretch out scope, when ensureing that pin stretches out in effective ultrasonic range.
Unscrew proximal lock gripping members 4, by near-end locking member 4 with go out pin regulating handle 5 and distally promote, until subscribe go out pin size till, locking.The numeral of now proximal lock gripping members 4 most proximal end display is out the total depth of pin.
Promote out pin regulating handle 5 and insert a needle into focus, now go out pin and regulate lock 6 can arrive handle 7 near-end.Take out nook closing member, connect ready vacuum injector, open three-way valve switch, open negative pressure, prepare to make a collection of specimens.For ease of collecting sample, repeatedly pin can be gone out by a small margin at biopsy sites.Be in spring when going out needle mould formula, one hand holds handle 7, and discharge by pressing pin regulating handle 5 (spring goes out pin mode) realizes automatically going out pin back stitching by the restoring force of spring.Be in when manually going out needle mould formula, manually promote/pull back out pin regulating handle 5 and can realize out pin/back stitching.
In the present embodiment, as one of another preferred version, also lock and handle can be regulated to be threaded connection by going out pin, when go out pin mode be spring go out pin time, go out pin regulate lock with handle by screw thread screw carry out spacing, make it not affect syringe push-and-pull, do not affect proximal lock gripping members and go out the promotion of pin regulating handle, when going out pin mode for manually going out pin, pin of outwarding winding out regulates the screw thread between lock and handle, is used pin regulating handle 5 and gone out pin to regulate lock 6 to be fixedly connected as entirety by position blocking pin and the combination of screens groove.
The invention provides a kind of ultrasonic pin; the method and access of this technical scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
