The suction pressure regulator 105 is formed in an arc shape having a radial groove on the outer circumferential surface so as to provide a good grip feeling so that the mounting groove 104 is exposed or concealed in accordance with the rotation angle of the suction pressure regulator 105, 104a are opened and closed.

The driving body 2 has a driving shaft 201 protruding forwardly and a motor connecting shaft 202 formed at the rear thereof and a motor connecting shaft 202 is decelerated by the deceleration means 203 to rotate the front drive shaft 201. [

It is preferable to use a planetary gear for the deceleration means 203, but it is not limited to this.

The rotating body 3 is coupled with the driving shaft 201 and rotates integrally with the driving shaft 201.

A suction passage 302 is formed in the center of the rotary body 3 and an annular groove 303 connected to the suction passage 302 is formed on an outer circumferential surface of the rotary body 3, Saline, blood, inflammation, and the like, which are introduced into the suction passage 103a through the suction passage 302, are discharged into the annular groove 303 and then discharged to the suction device through the suction connection pipe 103a.

A male coupling portion 301 is formed in front of the rotating body 3 so that a female coupling portion 406 formed behind the saber 405 of the saber blade 4 can be engaged and engaged, 3 or the like flows through the suction passage 302 of the rotating body 3 and is discharged into the annular groove 303 of the rotating body 3, do.

The saver blade 4 is integrally formed with a protective pipe 402 having an exposure hole 402a formed at one end thereof at a front end thereof and a saline solution supply pipe connection part 403 communicating with the inside of the protective pipe 402 is formed at one side thereof A tube support (401); And a body 404 formed at a front portion thereof with a saber 405 to be inserted into the protective pipe 402 and having a female coupling portion 406 engaged with the male coupling portion 301 at the rear thereof.

The saline solution supply pipe connection part 403 is connected to the saline solution supply device and the saline solution supply pipe 403a so that the saline solution supplied through the saline solution supply device can be discharged to the outside through the exposure hole 402a formed at the front end.

The saver 405 is formed in a tubular shape and has a serrated portion 405a formed at the front end portion thereof for scratching and removing the inflammation of the affected portion while rotating inside the protective tube 402, The inflammatory decomposition product removed by the exposed serrated portion 405a is sucked through the inside of the saber 405 and discharged through the suction device.

It is to be noted that the saline supply device and the suction device can use known devices commonly used in the technical field of the present invention.

Hereinafter, the operation of the medical handpiece to which the technique of the present invention is applied will be described with reference to the accompanying drawings.

1 to 5, a saber blade 4 is coupled to a chucking portion 101 formed on the front of the body 1, and a motor connecting portion 102 formed on the rear of the body 1 is provided with an inner motor connecting shaft 202 are engaged with the rotation axis of the motor 5 so as to be engaged with each other.

The suction connection pipe 103a formed on the body 1 is connected to the suction device by a suction hose 103a and the connection pipe 403 formed on the saber blade 4 is connected to a saline solution supply device and a saline solution supply pipe 403a .

Therefore, when the user inserts the end of the protective tube 402 of the saber blade 4 into the internal lesion of the patient who has developed inflammation or the like, approaches the exposure site 402a of the protection tube 402 to the inflammation site, When the operation of the motor is controlled by using the apparatus, the serpent 405 of the saber blade 4 rotates at a high speed by the motor, and the tooth portion 405a formed at the end of the saber 405 scrape off the inflammation of the affected part .

In the case where the irritation site is cleaned or the bleeding site is washed in the irritation site during the inflammation removal process, if the saline solution is supplied using the saline supply device, the saline solution is supplied by the supply pressure of the saline supply device. Through the exposure hole 402a of the protective pipe 402 as shown in Fig.

As described above, the inflammatory decomposition product removed by the saber 405 or the saline solution used in the inflammation removal process is introduced into the tubular saber 405 through the toothed portion 405a formed at the end of the saber 405 And is discharged through the annular groove 303 formed on the outer peripheral surface of the rotating body 3 after moving to the rotating body 3 in which the suction passage 302 is formed by the suction pressure of the suction device.

Since the annular groove 303 of the rotating body 3 is connected to the inside of the suction connection pipe 103a formed at one side of the outer circumferential surface of the body 1 in spite of the rotation of the rotating body 3, The saline solution, the blood, the inflammatory decomposition product, etc. that have flowed through the suction passage 302 of the suction passage 302 are discharged to the annular groove 303 and then quickly discharged through a suction device connected to the suction connection pipe 103a and the suction hose 103a .

An annular mounting groove 104 is formed on an outer circumferential surface of the body 1 and a valve hole 104a is formed in a bottom surface of the mounting groove 104 to pass through the inside and outside of the circumferential wall. A suction pressure adjusting member 105 for selectively opening the suction hose 103a and the suction hose 103a is rotatably installed in the mounting groove 104 to connect the suction connection pipe 103a and the suction hose 103a, The suction pressure regulator 105 is rotated to regulate the degree of opening of the valve hole 104a so that outside air can be introduced through the valve hole 104a and the suction pressure can be easily adjusted.
