Description
Technical field
The present invention relates to area of medical devices, especially a kind of safe locking device.
Background technology
Under the guiding of ultrasonic bronchoscope/endoscopic ultrasonography, tissue or cytological samples are obtained after puncture suction, are clinical
On the EBUS/EUS that often claims check.EBUS can pass through the specific location (conventional bronchoscope of lesion outside localization by ultrasonic bronchus
Can see the lesion in trachea-bronchial epithelial cell), and blood vessel is avoided under the guiding of color Doppler, pass through needle suction and biopsy
The cell and tissue for obtaining corresponding site, to achieve the purpose that diagnosed disease.EUS checks the primary tumo(u)r drawn game to cancer of pancreas
The accuracy of portion's tubercle by stages is higher.
The key that EBUS/EUS is checked is smoothly to obtain required tissue or cytological samples, biopsy needle for sampling
It is particularly important.After existing EBUS needles/EUS needles are in use, scheduled depth of needle determined by safety lock, manual driving handle
Go out needle, present safety lock is all to use rotation fixed or screw fixation method, generally two people is needed to coordinate, increases the behaviour of doctor
It is required, carrys out inconvenience to clinical operation out tape.
In the prior art, COOK products use screw tightened-up structure, and the structure operation is more complicated, need very great
Can lock-screw, doctor is time-consuming and laborious when operating, and MG using being rotated by 90 ° the function that mode reaches unlock and locking, hold by when operation
Easily obscure, which side does not know sometimes rotate toward, and need nurse to assist when rotation.
Invention content
Goal of the invention：The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of safety lock
Determine device.
In order to solve the above technical problem, the present invention provides a kind of safe locking device, including needle regulation pipe and can
The safety lock being locked in needle regulation pipe, the needle adjust tube outer surface and are equipped with tooth slot structure, and the safety lock includes safety lock
Unblock button and enclosing springs at an entirety and are coated on needle regulation pipe by lid, unblock button and spring, the safe locking closure
On, the unblock button is equipped with the protrusion being adapted to tooth slot structure, and spring is equipped between the needle regulation pipe and unblock button；
When mobile security is not locked, open-top unblock button and needle regulation pipe are distinguished in spring both sides so that convex in unblock button
Structure is played to be stuck in the tooth slot structure in needle regulation pipe；
When mobile security is locked, being unlocked by pressing button, spring compression, the bulge-structure in unblock button is from needle regulation pipe
It is removed in tooth slot structure, control safety lock adjusts pipe surface along needle and moves.
In the present invention, the tooth slot structure is two row, is symmetrically arranged at needle regulation pipe both sides.
In the present invention, the unblock button and spring are two, and each unblock button and spring form a locking list
Member is symmetricly set on the both sides of needle regulation pipe.
In the present invention, the tooth slot structure is spaced tooth, and two tooth centre positions are groove, groove size and solution
Lock the protrusion adaptation on button.
In the present invention, the tooth slot structure side is correspondingly provided with scale marker.
In the present invention, the safety lock is covered equipped with the through-hole being adapted to the press surface of unblock button, and unblock button is pressed
Pressure surface is buckled under the force of a spring in the through-hole of safe locking closure.
In the present invention, the safe locking closure is detachable structure.
Advantageous effect：Safety locking device only needs pressing safety lock button not put when operating, you can to move up and down
Safety lock may be implemented one-handed performance, and since safety lock Impact direction is vertical with button Impact direction, is further reduced completely
The risk of false triggering can meet doctor's requirement so safety lock positioning is reliable, have a vast market potentiality.
Description of the drawings
The present invention is done with reference to the accompanying drawings and detailed description and is further illustrated, it is of the invention above-mentioned or
Otherwise advantage will become apparent.
Fig. 1 is the explosive view of embodiment 1；
Fig. 2 is the structural schematic diagram of safety lock；
Fig. 3 is bump diagrams；
Fig. 4 is tooth slot structure schematic diagram；
Fig. 5 is design sketch.
Specific implementation mode
It elaborates to the present invention below in conjunction with attached drawing.
Embodiment 1；
Such as Fig. 1 and Fig. 2, the present invention includes needle regulation pipe 1, safe locking closure 2, tooth slot structure 3, unblock button 4, spring 6, leads to
Hole 9 and needle tubing 10,1 liang of symmetric outer surface of needle regulation pipe are equipped with tooth slot structure 3, and there are two safe locking closures 2, can mutually block solid
It is fixed, unblock button 4 is equipped in safe locking closure 2, safe locking closure 2 is detachable structure, forms an entirety after combination and coats
In needle regulation pipe, two parts are split as in the present embodiment, safe locking closure 2 is equipped with suitable with the press surface of unblock button 4
The press surface of the through-hole 9 matched, unblock button 4 is buckled under the active force of spring 6 in the through-hole of safe locking closure 2.
In the present embodiment, scale is divided on tooth slot structure 3.
Such as Fig. 3, unblock button 4 is equipped with protrusion 5, and protrusion 5 can stick into tooth slot structure 3.
Such as Fig. 4, tooth slot structure 3 is arranged in the outer surface of needle regulation pipe 1, and protrusion 5 can be stuck in different grooves, tooth socket
Structure is spaced tooth, and two tooth centre positions are groove, and tooth slot structure includes two groups, are symmetrically arranged at needle adjusting
The both sides of pipe 1.
Such as Fig. 5, safety is locked when in use, can use more than one, this embodiment takes two, is separately positioned on work
The both ends of fixed handle 8, to limit the position section of flexible handle 8.
Safety is locked when in use, and safety lock is placed on to the top of needle regulation pipe, and it is outer to ensure that needle does not expose in this way
Ultrasonic biopsy needle, is then put into endoscopic forceps channel, ultrasonic biopsy needle is fixed on scope by pipe, adjusts ultrasonic biopsy needle nozzle
Position can be seen just on scope, unclamp outer tube safety lock, latched position；Then according to the distance that go out needle, needle is adjusted out
The position of safety lock can start to puncture after regulating, and the effect of safety lock is to prevent from puncturing apart from overproof, and avoiding taking out need not
