Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to a multi-purpose artificial ossicular measuring device. Background Art

[0002] Conductive hearing loss is generally caused by middle ear diseases, including otitis media, otosclerosis, ossicular chain deformity, etc., and severe cases will affect daily communication. The most commonly used treatment method is ossicular chain reconstruction. Ossicular chain reconstruction requires the use of ossicular prostheses, and various artificial ossicular prostheses are available for clinical use. The required length of artificial ossicles varies from person to person, and accurately selecting artificial ossicles of appropriate length is crucial for postoperative hearing recovery. However, the three-dimensional spatial relationship between the human body's ossicles or between the ossicles and the eardrum is difficult to measure using current middle ear measuring instruments. Doctors can often only estimate the height of the ossicles by combining visual inspection with experience, which inevitably leads to errors and poor results in artificial ossicular implantation.

[0003] Therefore, we designed a multi-purpose artificial ossicular measuring device, which can conveniently measure the distances of multiple ossicular bones. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art. The utility model provides a multi-purpose artificial ossicular measuring device, which can be used to measure the distances of multiple ossicular bones.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a multi-purpose artificial ossicular measuring device, comprising:

[0006] A first circular sleeve, one end of which is connected to a second circular sleeve, and the first circular sleeve and the second circular sleeve are vertical;

[0007] A rotating rod is rotatably connected to the internal connection of the first circular sleeve and the second circular sleeve, a pulley is fixedly connected to the outer wall of the rotating rod, a measuring guide core is sleeved on the outer wall of the pulley, the lower measuring guide core of the pulley is arranged parallel to the first circular sleeve, and the upper measuring guide core of the pulley is arranged parallel to the second circular sleeve;

[0008] A notch is provided on the first circular sleeve, a hand-push adjustment button is provided at the notch, the measuring guide core is fixedly connected to the hand-push adjustment button, a measuring scale mark is provided at the notch, and the hand-push adjustment button and the measuring scale mark are used together to display the forward distance of the measuring guide core, thereby obtaining the distance between the auditory ossicles of the human body or between the auditory ossicles and the eardrum.

[0009] Furthermore, the hand-push adjustment button is slidably connected to a limiting slide groove provided in the first circular sleeve in a left-right limiting manner.

[0010] Furthermore, one end of the measuring guide core is fixedly connected with a rubber ball, and the initial position of the rubber ball is placed in the second circular sleeve.

[0011] Furthermore, an outer wall of the first circular sleeve is sleeved with an arc-shaped mounting plate, and a leading edge plate is fixedly connected to one side of the arc-shaped mounting plate.

[0012] Furthermore, the measuring guide core is made of flexible steel wire.

[0013] Compared with the prior art, the beneficial effects of the utility model include:

[0014] The measuring direction of the front end of the first circular sleeve after turning 90 degrees is exactly parallel to the direction of the stapes, which is suitable for measuring the distance between the stapes and the handle of the malleus or the tympanic membrane, which is also the length required for implanting the artificial ossicle.

[0015] The measuring guide starts from a certain point and can be extended to the measuring target directly, which provides a better observation field and makes the measurement more convenient and accurate.

[0016] By skillfully rotating or shaking the first circular sleeve, you can achieve multi-directional and multi-angle measurements.

[0017] After adding the front edge plate, the part of the front edge plate beyond the turning point can be placed on the surface of the long leg of the incus, and the measuring guide core can be extended downward to measure the distance between the long leg of the incus and the window point of the stapes base plate;

[0018] In the past, the measuring scale was at the front end, which was difficult to see clearly in the surgical field. The scale reading of this measuring instrument is on the first circular sleeve, which is convenient for reading. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0026] Example:

[0027] like Figure 1-4 As shown, the right end of the first circular sleeve 1 is connected to the second circular sleeve 2, and the first circular sleeve 1 and the second circular sleeve 2 are vertically arranged.

[0028] A rotating rod 10 is rotatably connected at the internal connection point between the first circular sleeve 1 and the second circular sleeve 2, a pulley 11 is fixedly connected to the outer wall of the rotating rod 10, a measuring guide core 7 is sleeved on the outer wall of the pulley 11, the measuring guide core 7 at the bottom of the pulley 11 is arranged parallel to the first circular sleeve 1, the measuring guide core 7 at the top of the pulley 11 is arranged parallel to the second circular sleeve 2, and a rubber ball 12 is fixedly connected to the top of the right end of the measuring guide core 7.

[0029] The measuring guide core 7 is made of flexible steel wire material.

[0030] A notch 3 is provided at the top of the limit slide 6, and a metering scale mark 4 is engraved on the notch 3. A hand-push adjustment button 5 is slidably connected to the notch 3, and the highest level of the hand-push adjustment button 5 is higher than the highest level of the first round sleeve 1. The limit slide 6 is slidably connected to the limit slide 6 inside the first round sleeve 1 in a left-right limit sliding manner. The measuring guide core 7 is fixedly connected to the hand-push adjustment button 5.

[0031] An arc-shaped mounting plate 8 is sleeved on the first circular sleeve 1 , and a front edge plate 9 is fixedly connected to one side of the arc-shaped mounting plate 8 .

[0032] In specific implementation, when in use, the turning point of the first circular sleeve 1 and the second circular sleeve 2 can be used as a fulcrum to rest on a target structure of the middle ear, and then the measuring guide core 7 is pushed out, and the tip of the measuring guide core 7 can be directly seen to reach another measurement target. The measured length can be read from the scale on the handle push button;

[0033] By using the turning point of the first circular sleeve 1 and the second circular sleeve 2 as a fulcrum to shake the first circular sleeve 1, or by rotating the first circular sleeve 1, multi-directional three-dimensional spatial measurement of the middle ear can be achieved, such as the distance measurement between the stapes head and the handle of the malleus, and the distance measurement between the handle of the malleus and the bottom plate of the stapes. After adding the front edge plate 9, the part of the front edge plate 9 that exceeds the turning point can be placed on the surface of the long leg of the incus, and the measuring guide core 7 extends downward to measure the distance between the long leg of the incus and the window point of the bottom plate of the stapes. By flexibly using this measuring device, it is possible to accurately select artificial ossicles or artificial stapes of appropriate length for precise hearing reconstruction.
