Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and more particularly to an external ear measuring instrument for plastic surgery. Background Art

[0002] An external ear meter is a device used to measure the structure of the external auditory canal. It is mainly used for otology diagnosis, hearing aid fitting, ear canal health assessment, and ear-related scientific research. This type of equipment is usually used to measure various physical parameters of the ear, such as the shape, size, and angle of the ear canal, etc., and these measurement data can help doctors make diagnoses or choose appropriate ear devices.

[0003] In the prior art, the diameter of the curved part of the external auditory canal is measured mainly by manual measurement or digital otoscope. Manual measurement mainly uses an otoscope to observe the internal structure of the external auditory canal and roughly judge the diameter of the ear canal through the lens field of view. In some cases, the doctor will use a ruler to measure the diameter. Although this method is relatively simple and does not require expensive equipment and can directly observe the health of the external auditory canal, the accuracy obtained is limited and it is more dependent on the experience and skills of the operator. For this reason, the prior art proposes a digital otoscope, which uses a high-resolution endoscope to examine the ear canal, take clear images and videos of the ear canal, and calculate the diameter of the ear canal through dedicated image analysis software. Although this method can make the measurement result more accurate, the cost of this equipment will increase geometrically compared to manual measurement, and the difficulty of operation will also increase.

[0004] In view of the above situation, the present invention designs an external ear measuring instrument for plastic surgery to solve the above technical problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an external ear measuring instrument for plastic surgery, which solves the problem that when measuring the external auditory canal diameter, the curved part of the external auditory canal has a complex shape and the ruler cannot be inserted for accurate measurement, thereby reducing the accuracy of the measurement result.

[0007] Preferably, a connection block is provided on one side of the fixing disk, and an airbag is provided on the other side of the fixing disk, and the diameter of the airbag is consistent with the diameter of the fixing disk.

[0008] Preferably, a limiting groove is provided above the movable groove, and the limiting groove passes through the connecting block, and mounting grooves are symmetrically provided on both sides of the limiting groove, and scale blocks are provided in the mounting grooves.

[0009] Preferably, a limiting column is provided on one side of the moving rod, and the limiting column is arranged in the limiting groove, an arc block is provided at one end of the moving rod away from the limiting column, and a sponge block is provided at one end of the arc block away from the moving rod.

[0010] Preferably, the control mechanism includes a control rod, a connecting rod and a connecting spring. The control rod is slidably arranged in the motion cavity, and one end of the control rod is arranged in the sponge block. The other end of the control rod is provided with a rectangular groove, and a control spring is arranged in the rectangular groove. One end of the control spring is connected to the control rod, and the other end is connected to the inner wall of the motion cavity. Connecting rods are symmetrically arranged on both sides of the control rod, and the connecting rods are arranged in sliding grooves provided on the limit columns, and the connecting rods are connected to the inner wall of the motion cavity through connecting springs.

[0011] Preferably, one end of the control rod is symmetrically provided with inclined surfaces, and the control rod reciprocates in the motion cavity, and the connecting rods arranged on both sides of the control rod are pushed toward the inner wall of the motion cavity through the inclined surfaces.

When the connecting rod moves toward the inner wall of the motion cavity, the conical protrusion contacts the scale block.

[0013] Beneficial effects of the present invention:

[0014] 1. The present invention provides an external ear measuring instrument for plastic surgery. The device inputs compressed gas into a circulation cavity through a hose, and the compressed gas in the circulation cavity flows toward the bellows. When the compressed gas fills the circulation cavity and the bellows, the bellows pushes the moving rod to move toward one side of the moving groove. At this time, the sponge block arranged at the front end of the moving rod fits the inner wall of the external auditory canal. Since the inner wall of the external auditory canal is not a regular shape, multiple moving rods are pushed to fit the inner wall of the external auditory canal through multiple bellows. When one group of moving rods fits the inner wall of the external auditory canal, the compressed gas pushes the remaining moving rods to fit the inner wall of the external auditory canal. The fit of multiple moving rods to the inner wall of the external auditory canal can accurately measure the diameter of the curved part of the external auditory canal. The sponge block can prevent the patient from experiencing pain when the moving rods fit the patient's external auditory canal.

[0015] During the chip lamination operation, another set of stages can perform chip pre-installation. When one set of stages completes the chip lamination operation,

[0016] 2. The present invention provides an external ear measuring instrument for plastic surgery. The device uses a control mechanism. When the moving rod fits the inner wall of the external auditory canal, the control rod inside the moving rod moves inward. The movement of the control rod pushes the connecting rod to move toward the scale blocks on both sides, and an indentation is left on the scale block through the conical protrusion on the connecting rod. When the fixed plate is removed from the patient's external auditory canal, the doctor can restore the diameter of the patient's internal external auditory canal by moving multiple moving rods to the scale position, thereby not only obtaining the accurate diameter of the curved part of the external auditory canal, but also explaining the ear condition to the patient. The air bag on one side of the fixed plate can prevent the patient from feeling uncomfortable during the measurement process. BRIEF DESCRIPTION OF THE DRAWINGS

The device body 1 transports compressed gas to the circulation cavity 211 through the hose 11. The compressed gas pushes the bellows 3 to expand through the air inlet 221. The expansion of the bellows 3 drives the moving rod 4 to move toward the inner wall of the external auditory canal. When one end of the moving rod 4 fits against the inner wall of the external auditory canal, the control mechanism 5 expands, thereby marking on the connecting block 21. When the compressed gas is discharged through the hose 11, the control mechanism 5 contracts and resets.

[0027] Specifically, a connection block 21 is provided on one side of the fixing disk 2 , and an air bag 24 is provided on the other side of the fixing disk 2 . The diameter of the air bag 24 is consistent with the diameter of the fixing disk 2 .

[0028] Specifically, a limiting groove 222 is provided above the movable groove 22 , and the limiting groove 222 penetrates the connecting block 21 , and mounting grooves 23 are symmetrically provided on both sides of the limiting groove 222 , and a scale block 231 is provided in the mounting groove 23 .

[0029] Specifically, a limiting column 41 is provided on one side of the moving rod 4, and the limiting column 41 is arranged in the limiting groove 222, an arc block 42 is provided at one end of the moving rod 4 away from the limiting column 41, and a sponge block 43 is provided at one end of the arc block 42 away from the moving rod 4.

[0030] Specifically, the control mechanism 5 includes a control rod 51, a connecting rod 52 and a connecting spring 53. The control rod 51 is slidably arranged in the motion cavity 44, and one end of the control rod 51 is arranged in the sponge block 43. A rectangular groove 512 is provided at the other end of the control rod 51. A control spring 513 is provided in the rectangular groove 512. One end of the control spring 513 is connected to the control rod 51, and the other end is connected to the inner wall of the motion cavity 44. Connecting rods 52 are symmetrically arranged on both sides of the control rod 51. The connecting rods 52 are arranged in the sliding grooves provided on the limit column 41, and the connecting rods 52 are connected to the inner wall of the motion cavity 44 through the connecting springs 53.

[0031] Specifically, an inclined surface 511 is symmetrically provided at one end of the control rod 51 . The control rod 51 reciprocates in the motion cavity 44 , and the connecting rods 52 arranged on both sides of the control rod 51 are pushed toward the inner wall of the motion cavity 44 through the inclined surface 511 .

[0032] Specifically, the connecting rod 52 has a "Z"-shaped structure, one end of the connecting rod 52 is connected to the inner wall of the motion cavity 44 through a connecting spring 53, and the other end of the connecting rod 52 is provided with a conical protrusion 521. When the connecting rod 52 moves toward the inner wall of the motion cavity 44, the conical protrusion 521 contacts the scale block 231.

[0033] Working process and principle: the operator first places the fixing plate 2 on the curved part of the patient's external auditory canal through the hose 11. After the fixing plate 2 is inserted into the curved part of the external auditory canal, the operator delivers compressed gas into the hose 11. The compressed gas enters the circulation cavity 211 through the hose 11. When the circulation cavity 211 is filled with compressed gas, the compressed gas flows into the bellows 3 through the air inlet 221. After the bellows 3 and the circulation cavity 211 are filled with compressed gas, the bellows 3 will push the moving rod 4 to move toward the inner wall of the patient's external auditory canal. The sponge block 43 at one end of the moving rod 4 is connected with the inner wall of the patient's external auditory canal. When the inner wall of the external auditory canal is in contact with the patient, the control rod 51 inside the moving rod 4 is squeezed by the patient's external auditory canal and moves in the movement cavity 44. The control rod 51 is pushed to both sides by the inclined surface 511 set at one end during the movement. At this time, the conical protrusions 521 on both sides of the connecting rod 52 squeeze the scale block 231. Since the scale block 231 is made of a material similar to soft mud, when the scale block 231 is squeezed, an indentation will be left on the scale block 231. When one group of moving rods 4 is in contact with the inner wall of the external auditory canal, the moving rod 4 is squeezed. When the compressed gas is continuously delivered from the hose 11 to the circulation cavity 211, the compressed gas will drive the remaining moving rods 4 to fit the inner wall of the external auditory canal. When all the moving rods 4 fit the inner wall of the patient's external auditory canal, the control rods 51 provided inside all the moving rods 4 will push the corresponding connecting rods 52 to leave an indentation on the scale block 231. At this time, the delivery of compressed gas into the hose 11 is stopped, and the compressed gas is discharged through the hose 11. Since there is no compressed gas inside to expand the bellows 3, the bellows 3 contracts and drives the moving rods 4 to move inward. Move, the control rod 51 and the connecting rod 52 have no limit, the control rod 51 is reset by the corresponding control spring 513, and the connecting rod 52 is reset by the connecting spring 53. After the operator takes out the fixed plate 2, the position of the moving rod 4 can be reset according to the indentation left on the scale block 231, so as to calculate the diameter of the inner wall of the external auditory canal, and at the same time, the internal situation of the ear canal can be better explained to the patient, thereby obtaining a more accurate diameter of the inner wall of the external auditory canal on the one hand, and avoiding discomfort to the patient during the measurement process through the sponge block 43 and the air bag 24 on the other hand.
