Abstract

The utility model discloses an eardrum catheterization device. The eardrum catheterization device comprises a casing, a core bar, a buckling reset mechanism and a pistol-like handle, wherein the core bar is movably sleeved in the casing, the buckling reset mechanism is connected with the rear end of the core bar, and the pistol-like handle is connected with the rear end of the casing and forms an included angle of 50-90 degrees with the casing. In the operation process of the eardrum catheterization device, the thumbs and the middle fingers can not block ear holes, thus greatly improving the operation visual field and improving the accuracy of catheterization operation.

Description

A kind of Tube adapter for drum membrane

Technical field

This utility model belongs to field of medical appliances, is specifically related to a kind of Tube adapter for drum membrane.

Background technology

Used Tube adapter for drum membrane employing forefinger of the prior art and middle finger are combined the mode of withholding and breather are inserted in the otch of tympanum, in aforesaid operations process, because thumb and middle finger can cover earhole, and make the visual field of operation limited, cannot accurately reliably breather be placed accurately.

Utility model content

The purpose of this utility model is to overcome prior art defect, and a kind of Tube adapter for drum membrane is provided.

The technical solution of the utility model is as follows:

, comprise that a sleeve pipe, is movably set in the resetting-mechanism of withholding that core bar in sleeve pipe is connected with the rear end of core bar with, also comprise a pistol shape handle being connected with the rear end of sleeve pipe, the angle between this handle and sleeve pipe is 50-90 degree.

In a preferred embodiment of the present utility model, described handle and described sleeve pipe are structure as a whole.

In a preferred embodiment of the present utility model, the described resetting-mechanism of withholding comprises a button of withholding for forefinger, a back-moving spring and a pressure connecting rod, described handle is provided with through hole, described pressure connecting rod is set in described through hole, its rear end connects the rear end of described core bar after bending, and its front end connects described button, and described back-moving spring is set in presses outside connecting rod, button described in its one end contact, handle described in its other end contact.

In a preferred embodiment of the present utility model, the rear end of described pressure connecting rod is fixedly connected with the rear end of described core bar.

In a preferred embodiment of the present utility model, the front end of described pressure connecting rod is fixedly connected with described button.

The beneficial effects of the utility model are:

1, Tube adapter for drum membrane of the present utility model comprises a pistol shape handle being connected with the rear end of sleeve pipe, angle between this handle and sleeve pipe is 50-90 degree, makes in operating process, and thumb and middle finger can not block earhole, greatly improve the operation visual field, improved the accuracy of putting pipe operation;

2, the rear end of pressure connecting rod of the present utility model and the rear end of core bar are fixedly connected with, and press the front end of connecting rod to be fixedly connected with button, make it simple in structure, and parts are few, and not fragile, reliability is high.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below by the specific embodiment in connection with accompanying drawing, the technical solution of the utility model is further detailed and is described.

As shown in Figure 1, a kind of Tube adapter for drum membrane 1, what comprise that a sleeve pipe 11, is movably set in that core bar 12 in sleeve pipe 11 is connected with the rear end of core bar 12 with one withholds resetting-mechanism 13, also comprise a pistol shape handle 14 being connected with the rear end of sleeve pipe 11, the angle between this handle 14 and sleeve pipe 11 is 50-90 degree.

The described resetting-mechanism 13 of withholding comprises a button 131 of withholding for forefinger, a back-moving spring 132 and a pressure connecting rod 133, described handle 14 is provided with through hole 141, described pressure connecting rod 133 is set in described through hole 141, its rear end connects the rear end of described core bar 12 after bending, its front end connects described button 131, described back-moving spring 132 is set in presses outside connecting rod 133, button 131 described in its one end contact, handle 14 described in its other end contact.

Preferably, described handle 14 is structure as a whole with described sleeve pipe 11, and the rear end of described pressure connecting rod 133 is fixedly connected with the rear end of described core bar 12, and the front end of described pressure connecting rod 133 is fixedly connected with described button 131.

Operating process of the present utility model is as follows: the front end that breather is placed in to core bar 12 and sleeve pipe 11, hand-held handle 14, so that stretching in auditory meatus and by breather, the core bar 12 of sleeve pipe 11 is accurately placed in tympanum incision, forefinger is withheld button 131, so that core bar 12 retreats disengaging breather, and then by handle 14, core bar 12 is extracted out from auditory meatus, complete and put pipe operation.

The above, it is only preferred embodiment of the present utility model, therefore can not limit according to this scope that this utility model is implemented, the equivalence of doing according to this utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that this utility model contains.
