Description
Technical field
The present invention relates to area of medical devices, particularly a kind of safe locking device.
Background technology
Under the guiding of ultrasonic bronchoscope/ultrasonic endoscope, after puncture suction, obtain tissue or cytological samples, be clinical
The upper EBUS/EUS often claimed checks.EBUS can be by particular location (conventional the gas of the outer pathological changes of localization by ultrasonic bronchus
Guan Jing can only see the pathological changes being positioned at trachea-bronchial epithelial cell), and avoid blood vessel under the guiding of color Doppler, pass through
Pin inhales the cell with biopsy acquisition corresponding site and tissue, thus reaches the purpose of diagnosed disease.EUS checks pancreas
The primary tumo(u)r of cancer and local tuberosity accuracy by stages are higher.
What EBUS/EUS checked it is critical only that the tissue needed for obtaining smoothly or cytological samples, for the biopsy needle of sampling
Particularly important.When existing EBUS pin/EUS pin uses, after predetermined depth of needle is determined by safety lock, manually
Driving handle goes out pin, and present safety lock is all to use to rotate fixing or screw fixation method, typically needs two people to coordinate, increases
Add the operation requirement of doctor, implemented to bring inconvenience to clinical operation.
In prior art, COOK product uses screw tightened-up structure, and this structure operation is more complicated, needs very great
Ability lock-screw, wastes time and energy when doctor operates, and MG uses half-twist mode to reach to unlock and the function of locking,
Easily obscure during operation, sometimes do not know toward which side rotate, and need nurse to assist when rotating.
Summary of the invention
Goal of the invention: the technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of safety locking
Device.
In order to solve above-mentioned technical problem, the invention provides a kind of safe locking device, manage including pin regulation and can lock
Being scheduled on the safety lock on pin regulation pipe, described pin regulation tube outer surface is provided with tooth slot structure, and described safety lock includes safety lock
Lid, unblock button and spring, unblock button is become an entirety and is coated on pin regulation by described safe locking closure with enclosing springs
Guan Shang, described unblock button is provided with the projection adaptive with tooth slot structure, is provided with between described pin regulation pipe and unblock button
Spring；
Not during mobile security lock, spring both sides back down unblock button and pin regulation pipe respectively so that unlock the bulge-structure on button
It is stuck in the tooth slot structure on pin regulation pipe；
During mobile security lock, being unlocked by pressing button, spring compression, unlock the bulge-structure on button from pin regulation pipe
Removal in tooth slot structure, controls safety lock and moves along pin regulation tube-surface.
In the present invention, described tooth slot structure is two row, is symmetrically arranged at pin regulation pipe both sides.
In the present invention, described unblock button and spring are two, each unblock button and spring one lock cell of composition
It is symmetricly set on the both sides of pin regulation pipe.
In the present invention, described tooth slot structure is spaced tooth, and two tooth centre positions are groove, groove size and solution
Protruding adaptation on lock button.
In the present invention, described tooth slot structure side is correspondingly provided with scale marker.
In the present invention, described safety lock lid is provided with and unlocks the through hole of the press surface adaptation of button, unlocks the pressing of button
Face is buckled in the through hole of safe locking closure under the force of a spring.
In the present invention, described safe locking closure is detachable structure.
Beneficial effect: have only to press safety lock button during the operation of safety locking device and do not put, i.e. can move up and down safety lock,
One-handed performance can be realized completely, and owing to safety lock Impact direction is vertical with button Impact direction, the mistake reduced further
The risk triggered, so this safety lock location is reliable, can meet doctor and use requirement, have wide market potential.
Accompanying drawing explanation
With detailed description of the invention the present invention done below in conjunction with the accompanying drawings and further illustrates, the present invention above-mentioned or its
Advantage in terms of him will become apparent.
Fig. 1 is the explosive view of embodiment 1；

Fig. 5 is design sketch.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
Embodiment 1；
Such as Fig. 1 and Fig. 2, the present invention includes pin regulation pipe 1, safe locking closure 2, tooth slot structure 3, unlocks button 4, bullet
Spring 6, through hole 9 and needle tubing 10, pin regulation 1 liang of symmetric outer surface of pipe is equipped with tooth slot structure 3, and safe locking closure 2 has two
Individual, can mutually block fixing, in safe locking closure 2, be provided with unblock button 4, safe locking closure 2 is detachable structure, group
Form an entirety after conjunction and be coated on pin regulation pipe, the present embodiment is split as two parts, safe locking closure 2
It is provided with and unlocks the through hole 9 that the press surface of button 4 is adaptive, unlock the press surface of button 4 under the active force of spring 6
It is buckled in the through hole of safe locking closure 2.
In the present embodiment, graduate on tooth slot structure 3.
Such as Fig. 3, unlocking button 4 and be provided with protruding 5, projection 5 can stick in tooth slot structure 3.
