Detailed ways

As shown in Figure 1, it is the structural representation after the tympanic membrane perforation measuring instrument of the present utility model is assembled, as can be seen from the figure, the tympanic membrane perforation measuring instrument of the present utility model comprises: the first clamp rod and the second clamp rod hinged to each other; A measuring rail part for measuring the size of the tympanic membrane perforation connected to the front end of the pliers rod and the second pliers rod; The size of the divided rail caliper part.

Specifically, as shown in FIGS. 1-4 , the measuring rail part of the present utility model includes: a first measuring leg 3 and a second measuring leg 4 that can be opened and closed; wherein, a pair of measuring legs are arranged at the front end of the first clamp rod And the middle part is hinged with the first clamp rod respectively; wherein, the rear end of the pair of measuring feet and the front end of the second clamp rod are hinged respectively. The rail-dividing caliper part includes: a rounded square 5 fixedly installed at the rear end of the second clamp rod, which is an arc-shaped frame with a scale on the upper part for identifying the size (as shown in Figures 1 and 5, only a few are shown in the figure). scale); the pointer 6 whose lower part is hinged with the rear part of the first clamp lever and the rear part of the second clamp lever respectively, is located in the arc-shaped frame, and the arrow end of the upper part points to the scale on the rounded square 5. In design, the rounded square 5 and the pointer 6 can be installed on the same side of the rear of the first and second tongs (as shown in Figure 2).

As shown in FIG. 4 , the first pliers rod includes: a first pliers rod body 1 ; a first handle rod 10 which is perpendicular to the first pliers rod body 1 and is located at the rear part thereof and is easy to hold; The branch rod has a parallel rod body 12 parallel to the first clamp rod body 1 . The first measuring foot 3 is hinged with the front end of the first clamp rod body 1 , the second measuring foot 4 is hinged with the front end of the parallel rod body 12 , and the pointer 6 is hinged with the rear of the first clamp rod body 1 .

In addition, the first clamp rod may also include a pair of vertical rod bodies (as shown in Figure 3, Figure 4, Figure 1 ) that fixedly connect the two sides of the rear end of the parallel rod body 12 to the two sides of the first clamp rod body 1, respectively, A pair of vertical rod bodies, parallel rod bodies 12 and the first clamp rod body 1 enclose a cavity for the front end of the second clamp rod to pass through. Alternatively, a vertical plate (not shown in the figure) can also be used to connect the first clamp rod body 1 and the parallel rod body 12 together up and down, and a through hole for the front end of the second clamp rod to pass through is opened in the middle of the vertical plate. The front end of the second clamp rod passes through the cavity or through hole and is hinged with the rear end of the pair of measuring legs through the hinge shaft, so that the pair of measuring legs can rotate around the hinge shaft to open or close at a certain angle.

It should be noted that the pair of measuring feet is a pair of feet that are separated by a short distance, which is easy to enter the external auditory canal and then open. The front ends of the pair of measuring feet (that is, one end used to measure the perforation of the eardrum) can refer to the structure of the tool for measuring the diameter of the perforated eardrum in the prior art, so that the broad sides of the front ends of the pair of measuring feet can touch the edge of the perforated eardrum, here The front-end structure is not described in detail.

As shown in FIG. 1 and FIG. 5 , the second pincer bar of the present invention includes: a second pincer bar body 2 whose length extending direction is parallel to the first pincer bar body 1 , and can be positioned parallel to the bottom of the first pincer bar body 1 ; The middle and rear part of the pliers rod body 2 is connected obliquely and the second handle rod 13 is hinged with the first handle rod 10; wherein, the bottom of the fillet 5 is fixedly connected with the rear part of the second pliers rod body 2 (such as by bonding or welding or by screwed together, etc.).

Wherein, the middle and rear parts of the first tongs rod and the middle and rear parts of the second tongs rods are hinged together, so that the relative movement of the first tongs rod and the second tongs rod can drive the pair of measuring feet of the measuring rail to slightly stretch Open and drive the pointer of the track-dividing caliper to rotate relative to the circular scale, so that the tympanic membrane perforation size measured by a pair of measuring feet is displayed through the scale indicated by the pointer on the circular scale.

In order to make the first clamp rod and the second clamp rod hinged, correspondingly, the upper part of the first handle rod 10 for connecting the first clamp rod body 1 is the first hinge part, and the first hinge part is provided with a through-the-first hinge part. The thickness of the first hinge hole 11, the upper part of the second handle rod 13 for connecting the second clamp rod body 2 is the second hinge part, and the second hinge part is provided with a second hinge hole 14 that penetrates the thickness of the second hinge part, By passing the rotating shaft 9 through the first hinge hole 11 and the second hinge hole 14, the upper parts of the first handle rod 10 and the second handle rod 13 are hinged together, so that the first clamp rod can be relative to the second handle rod around the rotating shaft 9. Clamp lever rotates.

In order to facilitate the slight rotation of the first clamp rod relative to the second clamp rod, a ring-shaped handle 8 is provided at the lower part of the first handle rod 10 , and an annular handle 7 is also provided at the lower part of the second handle rod 13 . When in use, it can be operated with one hand to make the first handle rod 10 rotate slightly relative to the second handle rod 13, and through a slight angle of rotation, the first clamp rod body is driven to produce a horizontal direction (that is, with the second clamp rod body) relative to the second clamp rod body. The displacement of the rod body in the same direction as the extension direction of the length of the rod body, thereby driving a pair of measuring feet to open slightly to measure the size of the perforation of the eardrum through the pair of measuring feet. At the same time, driven by the first clamp rod body, the pointer moves Rotate (the bottom of the pointer is hinged to the second lever body) and point to the scale on the upper part of the rounded ruler. The difference between the scale when the pointer is not rotated and the scale after rotation is the size of the measurement hole after the pair of measuring feet are opened.

It should be noted that, since the first clamp lever and the pair of measuring feet are hinged respectively, in order to prevent the relative hinged components from interfering with each other during relative movement, the hinged hole used in the hinged connection can be a circular hole, or It can be an oblong hole (not shown in the figure).

The tympanic membrane perforation measuring instrument of the utility model operates a pair of hinged clamp rods for opening and closing a pair of measuring feet, pushes the pair of measuring feet to open and close and drives the pointer to rotate relative to the rounded ruler through the lever principle, the principle is simple and the operation is convenient. The first clamp rod and the second clamp rod are hinged to each other. When the first clamp rod rotates relative to the second clamp rod, it can drive the measurement rail part at the front end and the rail division caliper part at the rear end to act accordingly. The diameter of the tympanic membrane perforation can be opened at a small angle, and the size of the perforation measured by opening the small angle can be accurately displayed by the tracking caliper part. The size of the tympanic membrane perforation can be directly obtained at the site of the patient's examination, thus solving the problem that the perforation size cannot be directly obtained when the diameter of the tympanic membrane perforation is measured by conventional measuring tools.

Although the present utility model has been described in detail above, the present utility model is not limited thereto, and those skilled in the art can make modifications according to the principles of the present utility model. It should be understood as falling within the protection scope of the present invention.
