The gyro stick according to an embodiment of the present invention includes: an external casing (140); and a gyroscope (150) which is received in the external casing (140).

Description

A medical gyro stick

The present invention relates to a gyroscope, and more particularly to a medical gyroscope usable for measurement of a tilt of a calibration object or a tilt of a calibration assistant.

A gyro sensor is a sensor that provides information about how far an object has been tilted in the x, y, and z directions.

In other words, it refers to a sensor that can sense the tilted direction while sensing the tilted direction of the object.

This has been widely used not only in general industry but also in medical field.

However, the conventional medical gyro sensor has a very complicated structure, so that the manufacturing cost is high and the durability can not be secured.

The prior art German Patent No. 1,9942,573 provides a groove-like rod-shaped gyro sensor.

The gyro sensor of German Patent No. 1,9942,573 is formed in a rectangular parallelepiped shape and is characterized by a vibrator composed of a piezoelectric body.

However, according to such a conventional gyro sensor, there is a problem in that there is a limit to the measurement of the angular velocity more precisely because the vibration is generated.

Meanwhile, US Patent No. 8,720,270 discloses an apparatus for inserting a sensor into a joint and analyzing movement of X, Y, Z in three axial directions through data transmission.

However, the sensor and communication-related equipment of the conventional U.S. Patent No. 8,720,270, as in the related art, have a very complicated structure as in the prior art, so that the durability can not be secured.

As shown in FIG. 5, the mounting groove 531 may have a rectangular box shape. However, the mounting groove 531 is not limited thereto, and may be variously changed if the main body 600 has a shape that can be matched.

The pair of fixing grooves 512 and 522 are for fixing the gyro stick 1000 to the object. The gyro stick 1000 may be fixed to the inclination measuring object through a fixing means such as a ball valve or a fixing valve, wherein the fixing means is attached to the gyro stick 1000 through the pair of fixing grooves 512 and 522 .

In this embodiment, the portion of the outer casing 610, which is inserted into the mounting groove 531, has a rectangular box shape corresponding to the shape of the mounting groove 531.

A filling hole 611 is formed in the outer casing 610. The battery 650 in the main body 600 can be charged by inserting the terminal of the charging cable through the charging hole 611.

The gyroscope 630 corresponds to a sensor portion for measuring the tilt of the object on which the gyro stick 1000 is mounted.

The communication module 640 receives the tilt data measured by the gyroscope 630 and transmits the tilt data to an external computer (for example, a PC). For example, the communication module 640 can transmit data to an external computer through wireless communication with an external Bluetooth receptor (not shown).

The battery 650 is configured to supply power necessary for the operation of the gyroscope 150 and the communication module 160. By way of example, the battery 650 may be a battery. As another example, the battery 650 may be equipped with a rechargeable battery, in which case the battery 650 may be charged from time to time through the connection of the charging cable through the charging hole 611 described above.
