In describing the operation of the endoscope manipulation apparatus in the following description, the directions in which the respective components are driven will be described with reference to the upper, lower, left, and right directions of the attached drawings for convenience of explanation and understanding. Of course, the direction in which each constituent element is driven can be changed in accordance with the arrangement and operation of the endoscope manipulation apparatus, so that it should not be understood that the direction in which each constituent element described below is driven is limited to the scope of the present invention will be.

3 to 5 are operation diagrams showing the operation of the endoscope manipulation apparatus according to the present embodiment.

3 through 5, the user connects the probe 200 to the handpiece 300. That is, the user connects the probe connection unit 250 to the handpiece connection unit 370. The first wire connecting terminal 271a is connected to the first round wire connecting terminal 354a and the second wire connecting terminal 272a is connected to the second round wire connecting terminal 355a. Since the first wire connection terminal 271a and the first round wire connection terminal 354a are connected to the second wire connection terminal 272a and the second round wire connection terminal 355a as described above, Operation is possible.

At this time, the first elastic body 356 and the second elastic body 357 are supported by the support step 358 with a uniform elastic force, and the first round bar connection terminal 354a and the second round bar connection terminal 355a are elastically . The first round bar connecting terminal 354a and the second round bar connecting terminal 355a are spaced the same distance from the latching jaw 359 and the first rack 352 and the second rack 353 are located at the same height . A space is provided between the first and second round wire connecting terminals 354a and 355a and the engaging protrusion 359 so that the first and second round bars 354 and 355 can be linearly driven.

Subsequently, the user can upwardly drive the lever 330 to bend the probe 200 in the right direction. As the lever 330 is rotationally driven upward, the driving pinion 331 is rotationally driven in one direction.

If the acceleration / deceleration pinion (not shown) is connected to the drive pinion 331, the rotational direction of the driven pinion 351 can be determined according to the number of the acceleration / deceleration pinions (not shown) A description will be given of an embodiment in which the driven pinion 351 is connected to the drive pinion 331 for convenience of explanation and understanding.

Subsequently, the driven pinion 351 connected to the drive pinion 331 is rotationally driven in the other direction opposite to the drive pinion 331. As the driven pinion 351 is rotationally driven in the other direction, the first rack 352 is upwardly linearly driven and the first round bar 354 is upwardly linearly driven together with the first rack 352. As the first round bar 354 is driven upward, the first elastic body 356 made of a compression coil spring is compressed. The second rack 353 is driven in a downward straight line and the second round bar 355 is driven in a downward straight line together with the second rack 353 as the driven pinion 351 is rotationally driven in the other direction.

The first wire 271 connected to the first round bar 354 is pulled upward by the first round wire connection terminal 354a and the first wire connection terminal 271a as the first round wire 354 is driven upward . The second wire 272 connected to the second round bar 355 by the second round wire connection terminal 355a and the second wire connection terminal 272a is moved downward as the second round wire 355 is driven downward, Lt; / RTI > Thus, one end of the probe 200 can be bent in the rightward direction.

Thereafter, when the user releases the lever 330, the first rack 352 is downwardly linearly driven by the elastic force of the first elastic body 356. As the first rack 352 is downwardly linearly driven, the driven pinion 351 is rotationally driven in one direction. As the driven pinion 351 is rotationally driven in one direction, the second rack 353 is rotationally driven upward. Thus, the first rack 352 and the second rack 353 can be returned to the initial position before the user operates the lever 330 as described above.

Conversely, the user can drive the lever 330 to rotate downward in order to bend the probe 200 in the leftward direction. As the lever 330 is driven to rotate downward, the drive pinion 331 is rotationally driven in the other direction.

Subsequently, the driven pinion 351 connected to the drive pinion 331 is rotationally driven in one direction opposite to the drive pinion 331. As the driven pinion 351 is rotationally driven in one direction, the first rack 352 is downwardly linearly driven, and the first round bar 354 is downwardly linearly driven together with the first rack 352. As the first round bar 354 is driven downward, the first elastic body 356 made of a compression coil spring is compressed. As the driven pinion 351 is rotationally driven in one direction, the second rack 353 is driven in the upward direction and the second round bar 355 is driven in the upward direction with the second rack 353.

The first wire 271 connected to the first round bar 354 by the first round wire connection terminal 354a and the first wire connection terminal 271a is pulled downward as the first round wire 354 is driven downward . The second wire 272 connected to the second round bar 355 is moved upward by the second round wire connection terminal 355a and the second wire connection terminal 272a as the second round wire 355 is driven upward Lt; / RTI > Therefore, one end of the probe 200 can be bent in the left direction.

Thereafter, when the user releases the lever 330, the first rack 352 is linearly driven upward by the elastic force of the first elastic body 356. As the first rack 352 is linearly driven upward, the driven pinion 351 is rotationally driven in the other direction. As the driven pinion 351 is rotationally driven in the other direction, the second rack 353 is driven to rotate downward. Thus, the first rack 352 and the second rack 353 can be returned to the initial position before the user operates the lever 330 as described above.

As the user rotates the lever 330, the first round bar 354 and the second round bar 355 are spaced apart from each other as the lever is rotated and driven, And the probe 200 is linearly driven in the opposite direction while maintaining the distance, so that the probe 200 can be bent.

Therefore, the endoscope manipulating apparatus 100 according to the present embodiment can prevent interference between the components in the handpiece 300 during the bending operation of the probe 200, and the bending operation of the probe 200 can be smoothly performed .

The endoscope manipulating apparatus 100 according to the present embodiment is configured such that the first and second round rods 354 and 355 are linearly driven by an accurate gear ratio of the driven pinion 351 and the first and second racks 352 and 353, Since the distance is determined, precise bending control of the probe 200 is possible.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
