Description

A kind of safe locking device

Technical field

This utility model 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 (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 determined by safety lock, manual driving handle Going out pin, present safety lock is all to use to rotate fixing or screw fixation method, typically needs two people to coordinate, adds the behaviour of doctor It is required, implements 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 Energy lock-screw, wastes time and energy when doctor operates, and MG uses half-twist mode to reach to unlock and the function of locking, holds during operation Easily obscure, sometimes do not know toward which side rotate, and need nurse to assist when rotating.

Utility model content

Utility model purpose: technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that one Plant safe locking device.

In order to solve above-mentioned technical problem, this utility model provides a kind of safe locking device, including pin regulation pipe and Can be locked in the safety lock on pin regulation pipe, described pin regulation tube outer surface is provided with tooth slot structure, and described safety lock includes peace Full locking closure, unblock button and spring, unblock button is become an entirety and is coated on pin tune by described safe locking closure with enclosing springs On pipe joint, described unblock button is provided with the bulge-structure adaptive with tooth slot structure, between described pin regulation pipe and unblock button It is provided with spring；

Not during mobile security lock, spring both sides back down unblock button and pin regulation pipe respectively so that unlock on button is convex Play structure to be 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 this utility model, described tooth slot structure is two row, is symmetrically arranged at pin regulation pipe both sides.

In this utility model, described unblock button and spring are two, each unblock button and spring one lock of composition Cell is symmetricly set on the both sides of pin regulation pipe.

In this utility model, described tooth slot structure is spaced tooth, and two tooth centre positions are groove, groove size Adaptive with the bulge-structure unlocked on button.

In this utility model, described tooth slot structure side is correspondingly provided with scale marker.

In this utility model, described safety lock lid is provided with and unlocks the through hole of the press surface adaptation of button, unlocks button Press surface be buckled under the force of a spring in the through hole of safe locking closure.

In this utility model, 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, can realize one-handed performance completely, and owing to safety lock Impact direction is vertical with button Impact direction, reduce further The risk of false triggering, so this safety lock location is reliable, doctor can be met and use requirement, there is wide market potential.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is elaborated.

Embodiment 1；

Such as Fig. 1 and Fig. 2, this utility model includes pin regulation pipe 1, safe locking closure 2, tooth slot structure 3, unlocks button 4, 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, can mutually block Living fixing, be provided with unblock button 4 in safe locking closure 2, safe locking closure 2 is detachable structure, forms an entirety also after combination Being coated on pin regulation pipe, be split as two parts in the present embodiment, safe locking closure 2 is provided with and unlocks the pressing of button 4 The through hole 9 that face is adaptive, the press surface unlocking button 4 is buckled in the through hole of safe locking closure 2 under the active force of spring 6.

In the present embodiment, graduate on tooth slot structure 3.

Such as Fig. 3, unlocking button 4 and be provided with bulge-structure 5, bulge-structure 5 can stick in tooth slot structure 3.

Such as Fig. 4, tooth slot structure 3 is arranged on the outer surface of pin regulation pipe 1, and bulge-structure 5 can be stuck in different grooves, Tooth slot structure is spaced tooth, and two tooth centre positions are groove, and tooth slot structure includes two groups, is symmetrically arranged at pin The both sides of regulation pipe 1.

Such as Fig. 5, safety is locked in use, it is possible to use more than one, this embodiment takes two, is separately positioned on work The two ends of fixed handle 8, interval in order to limit the position of flexible handle 8.

Safety is locked in use, and safety lock is placed on the top of pin regulation pipe, outside so ensureing that pin does not expose Pipe, then puts in endoscopic forceps channel by ultrasonic biopsy needle, is fixed on scope by ultrasonic biopsy needle, regulate the ultrasonic biopsy needle mouth of pipe Position just can be seen on scope, unclamps outer tube safety lock, latched position；Then according to the distance of pin to be gone out, pin is adjusted The position of safety lock, can start after regulating to puncture, and the effect of safety lock is to prevent from puncturing apart from overproof, it is to avoid taking out need not The tissue wanted, and can avoid patient is produced injury.
