Description

Measurer for otolaryngological department

Technical Field

The utility model belongs to otolaryngology branch of academic or vocational study surgical instruments field especially relates to a carry out measuring caliber for otolaryngology branch of academic or vocational study to the stapes.

Background

In some otorhinolaryngological procedures, the surgeon needs to measure multiple dimensions on the stapes, which includes the stapes head, curved foot, straight foot, and the stapes fundus. The existing measuring tool is generally a vernier caliper, a doctor takes out a stapes from a human body and places the stapes under a microscope, the vernier caliper is used for measuring the size of a part to be measured of the stapes, the stapes are very small (the length is generally between 2-4 mm) and the structure is complex, the vernier caliper is very thick and bulky, the stapes cannot be clamped on the part to be measured and can only be suspended on the stapes for measurement, the doctor lacks an impact point during measurement, the weight of the vernier caliper is large, the gravity center is located at a measuring end (the end where two measuring claws are located), the gravity center is far away from a holding end, so that the doctor is easy to generate slight shake during measurement and operation deviation occurs, and therefore, the requirement on the operation of the vernier caliper is high. Meanwhile, the thickness of the measuring claw is large, when a microscope focuses on the stapes, the measuring claw is suspended above the stapes, the focal point of the microscope is far away, the edge of the measuring claw is fuzzy, a doctor is difficult to judge whether the measuring claw is aligned with the edge of the part to be measured, judgment deviation easily occurs, the doctor needs to measure for multiple times and take an average value to obtain a more accurate numerical value, and the requirement on the operation of the vernier caliper is also improved.

Therefore, measuring the stapes with the existing measuring tools has the disadvantage of high operational requirements.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a caliber for otolaryngology branch of academic or vocational study. With the utility model discloses measure the stapes and have the lower advantage of operating requirement.

The technical scheme of the utility model: the measurer for the ear-nose-throat department comprises a handle, wherein one end of the handle is connected with an outer tube, a stop block is arranged at the end part of the outer tube, a sliding groove close to the outer tube is formed in the handle, scales are arranged on two sides of the sliding groove, a push block is arranged in the sliding groove, a through hole is formed in the handle in the axial direction, a sliding block connected with the push block is arranged in the through hole, and a measuring wire penetrating through the outer tube is arranged.

In the above-mentioned measuring device for otolaryngological department, the outer tube is a hollow tube with a bending included angle.

In the above-mentioned measuring device for otolaryngological department, the handle is provided with concave surfaces located at both sides of the chute, and the scale is arranged on the concave surface.

In the above-mentioned caliber for otolaryngological department, the handle is provided with a through groove for communicating the chute with the through hole, the through groove is internally provided with a screw, and the push block is connected with the slide block through the screw.

In the above-described measuring instrument for otorhinolaryngological use, the measuring wire and the outer tube are both made of stainless steel.

In the above measurer for otolaryngological department, the top surface of the push block is provided with anti-slip lines.

Compared with the prior art, at first, the doctor adopts the utility model discloses when measuring the stapes, dog and stapes contact have given doctor's point of application of force, the production of reducible slight shake, moreover, the utility model discloses a structure is smaller and more exquisite, weight is lighter, and the focus is on holding end (handle), and the doctor of being convenient for is held, and the doctor is more difficult to produce slight shake when measuring, so the doctor is difficult to produce the operation deviation, and is consequently right the utility model discloses a requirement of operation is lower. Secondly, the utility model discloses a measure the silk and measure the position that awaits measuring, measure the silk thinner, be located near microscopical focus, the end that stretches out of measuring the silk can be compared to the clear observation of doctor, and whether the doctor judges the tip of measuring the silk easily and aligns with the edge at the position that awaits measuring, is difficult to appear judging the deviation, and the doctor once measures and can acquire comparatively accurate numerical value, and this has also reduced the utility model discloses requirement on the operation.

Thus, measuring the stapes with the present invention has the advantage of lower operational requirements.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. Measurer for otolaryngology branch of academic or vocational study, as shown in fig. 1, including handle 1, the one end of handle 1 is connected with outer tube 2, the tip of outer tube 2 is equipped with dog 3, the preceding terminal surface of dog 3 aligns with the tip of outer tube 2, be equipped with spout 4 near outer tube 2 on handle 1, the both sides of spout 4 all are equipped with scale 5, be equipped with ejector pad 6 in the spout 4, be equipped with through-hole 7 on the handle 1 axial, be equipped with the slider 8 of being connected with ejector pad 6 in the through-hole 7, be equipped with the measuring wire 9 that passes outer tube 2 on the slider 8, the tip of measuring wire 9 aligns with the tip of.

The outer tube 2 is a hollow tube with a bending included angle.

The handle 1 is provided with a concave surface 10 positioned at two sides of the sliding groove 4, and the scale 5 is arranged on the concave surface 10.
