Description

A kind of expander locking device

Technical field

The utility model belongs to medical instruments field, more particularly, to a kind of expander locking device.

Background technology

When the cavities such as the physiology inspections of female sex organs, rectal examination check, it will usually use expander.It uses at present Expander, be generally made of fixed leaf and movable leaf and handle, pass through the opposite of the hand-held handle portion of the upper page of control and inferior lobe Angle is opened and closed, to control the opening and closing degree of upper leaf and inferior lobe, achievees the purpose that retract cavity.

However when operating, since expander gos deep into that internal front space is limited, the lock setting of general fixed expander exists On rear side of expander, such design must operate shank by grip, and when retracting operation, be locked with another hand, It brings inconvenient.

Utility model content

For the disadvantages described above or Improvement requirement of the prior art, the utility model provides a kind of expander locking device, Its object is to the triggers and locker by facilitating index finger to operate, and thus solve existing to be expander locking device needs The technical issues of both hands operation locking.

To achieve the above object, according to the one side of the utility model, a kind of expander locking device is provided, including The trigger of control expander activity leaf folding and the lock being fixedly connected with handle, the trigger have trigger tongue, the lock With to the inclined pawl of handle orientations, when the trigger stress, moved to handle orientations, trigger tongue is slided along pawl, institute When stating trigger and not stressing, trigger tongue catches on the pawl to lock expander activity leaf.

Preferably, the expander locking device, trigger tongue and the movable connection of trigger, the trigger root of the tongue is according to its position It sets in locking or non-locking state；When the trigger tongue is in non-locking state, disengaged with the pawl of the lock.

Preferably, the expander locking device, trigger tongue are existed by being set to the control device of the trigger side Switch between lock-out state and non-locking state.

Preferably, the expander locking device, trigger tongue are connect by connecting rod with trigger, the connecting rod with pull Machine tongue is fixedly connected, with trigger edge and the movable connection of the trigger so that the trigger tongue is in the lock pawl Track or be detached from it is described lock pawl track so that the trigger tongue be in locking or non-locking state.

Preferably, the expander locking device, trigger both sides are connect equipped with button with the connecting rod.

Preferably, the expander locking device is set on front side of dilator handle.

Preferably, the expander locking device, lock are connect with handle by shrapnel.

Preferably, the expander locking device, lock use polystyrene plastics, the trigger tongue to be moulded using ABS Material.

Preferably, the expander locking device, the button in trigger tongue both sides is arranged, and there are different colours, button to adopt Use ABS plastic.

In general, the above technical solutions conceived by the present invention are compared with the prior art, due to trigger sample Locking device, setting with handle on front side of, can facilitate hold handle when, directly with index finger operation expander folding, can obtain Facilitate the advantageous effect of one-handed performance.

In all the appended drawings, identical reference numeral is used for indicating identical element or structure, wherein：

1 is trigger, and 11 be trigger tongue, and 12 be connecting rod, and 2 be lock, and 3 be shrapnel, 4 devices in order to control

Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.In addition, institute in the various embodiments of the present invention described below The technical characteristic being related to can be combined with each other as long as they do not conflict with each other.

Expander locking device provided by the utility model is preferably disposed on front side of dilator handle, as shown in Figure 1, packet Include trigger 1 and lock 2；

The trigger 1 has trigger tongue 11, the trigger tongue as shown in Fig. 2, for controlling the folding of expander activity leaf 11 are in locking or non-locking state with 1 movable connection of trigger, the trigger tongue 11 according to its position；The trigger tongue 11 is logical It crosses and is set to the control device 4 of 1 side of the trigger and switches between lock-out state and non-locking state.The trigger 1, preferably Using ABS plastic, it is suitble to ergonomic designs.

The lock 2, is fixedly connected with handle, has to the inclined pawl of handle orientations, is connected by shrapnel 3 with handle It connects；It is preferred that polystyrene plastics is used, and it is environmental-friendly, it is suitble to one-pass molding.

As shown in figure 3, when trigger tongue 11 is in the lock state, 1 stress of the trigger is then moved to handle orientations, is pulled Machine tongue 11 is slided along pawl, and when the trigger 1 does not stress, trigger tongue 11 catches on the pawl to lock expander activity Leaf；When the trigger tongue 11 is in non-locking state, disengaged with the pawl of the lock 2, the trigger 1 for being can backward lever side To movement, to return to original state.

It is embodiment below：

As shown in Figures 1 to 3, expander locking device provided by the utility model is set on front side of dilator handle, including Trigger 1 and lock 2；

The trigger 1, it is preferred to use ABS plastic is connect with the movable upper leaf of expander by reverse gear, has trigger Tongue 11, the trigger tongue 11 are connect by connecting rod 12 with trigger 1, and the connecting rod 12 is fixedly connected with trigger tongue 11, with institute State trigger 1 along with 1 movable connection of the trigger；1 both sides of the trigger are connect equipped with button with the connecting rod 12；By next The button of side may make connecting rod 12 to be displaced sideways with trigger action tongue 11, to be detached from the track of pawl so that the trigger tongue 11 are in non-locking state；Opposite, the button of the other side is pressed, connecting rod 12 may make to be resetted with trigger action tongue 11, to Return to the track of pawl so that the trigger tongue 11 is in the lock state.The button of 11 both sides of trigger tongue setting is respectively Green and red, when pressing the green button so that the trigger tongue 11 is in the lock state, when pressing red button so that The trigger tongue 11 is in non-locking state.
