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 gastroscope, after puncture suction, obtain tissue or cytological samples, be clinical
The upper EBUS/EUS often claimed checks.EBUS can (conventional bronchoscope be only by the particular location of the outer pathological changes of localization by ultrasonic bronchus
The pathological changes being positioned at trachea-bronchial epithelial cell can be seen), and avoid blood vessel under the guiding of color Doppler, inhaled by pin and biopsy
Obtain cell and the tissue of corresponding site, thus reach the purpose of diagnosed disease.EUS checks the primary tumo(u)r drawn game to cancer of pancreas
Tuberosity accuracy by stages in portion's is 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 locked by safety lock, manual driving handle
Going out pin, present safety lock mainly uses rotation fixing or screw fixation method, typically needs two handss to coordinate, adds the behaviour of doctor
Make difficulty, implement to bring inconvenience to clinical operation.
In prior art, the brand product such as COOK, Boston science, Olympus mainly uses screw tightened-up structure, should
Structure operation is more complicated, needs to apply bigger strength ability lock-screw, wastes time and energy when doctor operates, MG brand product
Main employing rotation mode reaches to unlock and the function of locking, and during operation, the direction of rotation of unblock and locking easily causes and obscures,
Make troubles to doctor's practical operation.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of reliable locking device of more convenient operation.
In order to solve above-mentioned technical problem, the invention provides a kind of safe locking device, including pin regulation pipe and safety
Lock, described pin regulation tube outer surface be provided with tooth slot structure, described safety lock include safety lock lower cover, safety lock upper cover, unlock by
Button and spring, safety lock lower cover and safety lock upper cover can mutually block fixing, unlock button and are arranged in safety lock lower cover, spring
Being arranged at safety lock lower cover and unlock between button, described safety lock lower cover and safety lock upper cover will unlock button and enclosing springs
Becoming an entirety and be coated on pin regulation pipe, described unblock button is provided with the projection adaptive with tooth slot structure,
Not during mobile security lock, spring top unwinds lock button so that unlocks the projection on button and is stuck on pin regulation pipe
In tooth slot structure；
During mobile security lock, being unlocked by pressing button, spring compression, unlock the teeth groove from pin regulation pipe of the projection on button
Removal in structure, controls safety lock and moves along pin regulation tube-surface.
Unblock button of the present invention includes pedestal and is positioned at the elastic arm of pedestal both sides, is provided with convex outside elastic arm
Rising, be provided with block and the groove suitable with projection inside safety lock lower cover, elastic arm both sides pass described block, described
Spring is unlocking between button and block.Bulge-structure design guarantees when not mobile security is locked, and bulge-structure is tied with teeth groove
Structure coordinates more closely more firm.When mobile security is locked, unlock button press relatively short stroke and i.e. can ensure that bulge-structure and teeth groove
Structure separates.
Tooth slot structure of the present invention is two row, is symmetrically arranged at pin regulation pipe both sides.
Tooth slot structure of the present invention can also be single-row, is arranged on pin regulation pipe side.
Spring of the present invention can be two or more.
Projection of the present invention is V-type, U-shaped, rectangle, trapezoidal or round.
Tooth slot structure of the present invention is horizontally disposed with or arbitrarily angled setting at pin regulation Guan Shangwei.
Tooth slot structure side of the present invention is correspondingly provided with scale marker, and it is fixed to carry out more accurately during mobile security lock
Position.
Tooth slot structure of the present invention is spaced tooth, and two tooth centre positions are groove, groove size and unblock
Protruding adaptive on button, interval arrange so that bulge-structure coordinate with tooth slot structure tightr more firm.
The invention have the benefit that safety locking device has only to press safety lock button and do not puts when operating,
To 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 risk of the false triggering reduced further, so this safety lock location is reliable, can meet doctor and use requirement, have wide city
Field potentiality.
