A torque generated as a result of rotation of the second transmission screw 322 actuated by the second driver 324 is transmitted to drive movement of the second slider 323 along the second guide rails 321 in the first direction 801.

In this embodiment, each of the first driver 315 and the second driver 324 is composed of a drive motor, such as a step motor, and a gear speed reducer. Since the construction of the first and second drivers 315, 324 is of a known type, a detailed description thereof is dispensed with.

With reference to FIGS. 1, 3, 4 and 5, the seat mechanism 4 is mounted on the second slider 323 to be moved horizontally with the second slider 323. The seat mechanism 4 includes a mounting seat 41 which is mounted below the second slider 323, a rotary seat 42 which is rotatably mounted on the mounting seat 41 about a horizontal axis in the first direction 801, and a rotation driver 43 which is mounted on the mounting seat 41 and coupled with the rotary seat 42.

Specifically, the first height adjusting driver 513 includes a first transmission rack 514 which is securely disposed on the first holder 512 and which extends in the up-down direction, a first drive motor 515 which is mounted within the first housing 511, and a gear speed reducer 516 which is coupled with the first drive motor 515 and which meshes with the first transmission rack 514. The first drive motor 515 is controlled and operated to transmit a drive through the gear speed reducer 516 and the first transmission rack 514 to move the first holder 512 relative to the first housing 511 in the up-down direction so as to adjust the downward extending length of the first holder 512 relative to the first housing 511. In this embodiment, the first drive motor 515 is a step motor which is coupled with the gear speed reducer 516 to minutely adjust the height of the first holder 512.

The microscopic image capturing unit 52 includes a suspending arm 521 which is mounted on a lower end of the first holder 512 and which extends in the first direction 801 to have two opposite ends, two shafts 522 which are telescopically mounted on the suspending arm 521 and which respectively extend from the ends in the first direction 801, a driving module 523 which is mounted on the suspending arm 521 and which are coupled with the shafts 522, and two microscope lenses 524 which are respectively mounted on the shafts 522.

The driving module 523 is composed of a drive motor and gear speed reducer assemblies coupled with the drive motor and the shafts 522. Since the construction of the driving module 523 is of a known type, a detailed description thereof is dispensed with.

The microscope lenses 524 are electronic microscope lenses which microscopically capture images, and sends the captured images to a display device (not shown) for processing and display output.

Each of the microscope lenses 524 is disposed to microscopically capture images of the biosamples 901 in the sample container 900. In this embodiment, the microscope lenses 524 respectively have optical axes which extend and are inclined toward the second direction 802 and which extend downwardly and toward each other to intersect each other at a lower portion of the processing mechanism 6. In other embodiments, the optical axes of the microscope lenses 524 intersect by an adjustable angle, such as 45 degrees, 90 degrees, etc. Moreover, through the adjustment of the shafts 522 relative to the suspending arm 521, the direction of the optical axes of the microscope lenses 524 may be adjusted.

With reference to FIGS. 3, 7 and 8, the processing mechanism 6 is mounted on the rotary seat 42 to be rotated with the rotary seat 42. The processing mechanism 6 includes a second height adjusting unit 61 which is mounted on the rotary seat 42, a third height adjusting unit 62 which is mounted on the second height adjusting unit 61, and a processing unit 63 which is mounted on the third height adjusting unit 62.

Specifically, the second height adjusting unit 61 includes a second housing 611 which is securely mounted on the rotary seat 42 and which extends in the up-down direction, a second holder 612 which is movably mounted on the second housing 611 in the up-down direction and which is connected with the third height adjusting unit 62, and a second height adjusting driver 613 which is mounted on the second housing 611 and which is coupled with the second holder 612. The second height adjusting driver 613 includes a second drive motor 614 which is mounted on an upper end of the second housing 611, and a second transmission rack 615 which is securely mounted on the second holder 612 and which extends in the up-down direction. The second drive motor 614 is coupled with the second transmission rack 615 and is controlled and actuated to transmit a drive through the second transmission rack 615 to move the second holder 612 relative to the second housing 611 in the up-down direction so as to adjust the downward extending length of the second holder 612 relative to the second housing 611. In this embodiment, the second drive motor 614 is a step motor.

The third height adjusting unit 62 is mounted between the second height adjusting unit 61 and the processing unit 63. The third height adjusting unit 62 includes a third housing 621 which is securely mounted on the second holder 612, a third holder 622 which is movably mounted on the third housing 621 in the up-down direction, and a third height adjusting driver 623 which is mounted on the third holder 622 and which is coupled with the third housing 621. The third height adjusting driver 623 includes a third transmission rack 624 which is securely mounted on the third housing 621 and which extends in the up-down direction, a third drive motor 625 which is mounted on the third holder 622, and a gear speed reducer 626 which is mounted on the third holder 622 and which is coupled with the third drive motor 625 and the third transmission rack 624.

The third drive motor 625 is controlled and operated to actuate movement of the third holder 622 relative to the third housing 621 in the up-down direction through the gear speed reducer 626 and the third transmission rack 624.

The processing unit 63 is mounted on the second holder 612. Thus, the third height adjusting unit 62 is controlled and actuated to move the processing unit 63 relative to the sample container 900 in the up-down direction. The second height adjusting unit 61 is driven to move the processing unit 63 in the up-down direction through the third height adjusting unit 62.

In this embodiment, the tooth pitch of the third transmission rack 624 is smaller than that of the second transmission rack 615. That is, the processing unit 63 is moved by the second height adjusting unit 61 with a moving route that is different from a moving route with which the processing unit 63 is moved by the third height adjusting unit 62. Specifically, by the second height adjusting driver 613, the second holder 612 is adjusted and moved at a relatively larger range. By the third height adjusting driver 623, the third holder 622 is adjusted and moved at a relatively minor range.

The processing unit 63 may be in the form of a tube which is connected and in communication with a driving equipment (not shown), or an electronic device which is in signal connection with a driving equipment (not shown). For example, the processing unit 63 may be a sampling cannula, an injection syringe, a laser device, an etching device, etc.

The processing unit 63 is movable downwardly with the second holder 612 to be interposed between the microscope lenses 524 and to reach a field of view of the microscope lenses 524 and into the sample container 900. Also, the processing unit 63 is operable and driven to perform suction, injection, etching or perforation process on the biosamples 901 in the sample container 900. The injection process may include a process of injecting sperm, DNA, cell tissues, etc. Besides, the processing unit 63 may be adapted, but not limited, to hold an injection unit, a pipette unit, a piezoelectric unit, a laser unit, etc.

The tip camera 7 is mounted on a bottom end of the third holder 622, and has a vision which is parallel to the direction of the processing unit 63 to capture image of the bottom portion of the processing unit 63 to feedback the captured vision in the tip camera 64 for facilitating positioning of the processing unit 63 and monitoring the operation of the processing unit 63.

With reference to FIGS. 1 and 2, when the microscopic operating device is operated to perform a processing operation on the biosamples 901 in the sample container 900 therebelow, the first drivers 315 and the second driver 324 of the movement adjusting mechanism 3 are operated to adjust the position of the second movement adjusting module 32 in the second direction 802 and further adjust the position of the second slider 323 in the first direction 801 such that the seat mechanism 4 is moved to bring the microscopic image capturing mechanism 5 and the processing mechanism 6 to a desired horizontal position above the sample container 900.

With reference to FIGS. 2, 6 and 9, subsequently, the first height adjusting driver 513 is operated to move the microscopic image capturing unit 52 downwardly through the first height adjusting unit 51 such that the sample container 900 is placed within the field of view of the microscope lenses 524. Also, according to the imaging requirement, the driving module 523 is operated to actuate movement of the shafts 522 in the first direction 801 so as to adjust the field of view of each microscope lens 524. Moreover, with the operation of the rotation driver 43 to actuate rotation of the rotary seat 42, an angular movement of the first height adjusting unit 51 and the second height adjusting unit 61 is actuated for further adjusting the fields of view of the microscope lenses 524.

When the microscopic operating device is operated to perform a processing operation to the biosamples 901 in the sample container 900, the second height adjusting unit 61 is operated to move the second holder 612 downwardly, and the third height adjusting unit 62 and the processing unit 63 are moved rapidly so as to place the processing unit 63 in the field of view of the microscope lenses 524. Hence, the position of the processing unit 62 relative to the biosamples 901 in the sample container 900 can be observed from different angles. Meanwhile, cooperating with the tip camera which captures the image of the bottom portion of the processing unit 63, the position of the processing unit 63 relative to the biosample 901 to be processed is observed to monitor the operation of the processing unit 63.

Subsequently, through operation of the third height adjusting driver 623 of the third height adjusting unit 62 (see FIG. 8), the processing unit 63 is minutely moved downwardly relative to the biosamples 901 in the sample container 900. The user, with the aid of the microscopic images captured by the microscope lenses 524, can precisely operate the third height adjusting driver 623 so as to perform the processing procedure on the predetermined biosamples 901, such as sampling, injection, etching, perforation, etc.

With reference to FIG. 1, moreover, through the movement adjusting mechanism 3 which is movable to adjust the seat mechanism 4, the microscopic image capturing mechanism 5 and the processing mechanism 6 in the first direction 801 and the second direction 802, a plurality of the sample containers 900 with biosamples 901 therein can be placed below the processing mechanism 6 and spaced apart from each other. Then, with the horizontal adjustment of the seat mechanism 4 by means of the movement adjusting mechanism 3, the microscopic image capturing mechanism 5 and the processing mechanism 6 are adjusted synchronously relative to the sample containers 900 so as to perform the processing procedure on each sample container 900.

As illustrated, with the microscope lenses 524 of the microscopic image capturing mechanism 5 and the processing unit 63 of the processing mechanism 6 adjustable and movable to be placed within the field of view of the microscope lenses 524, during the processing procedure, the position of the processing unit 63 relative to the biosamples 901 in the sample container 900 can be observed from different angles by the microscope lenses 524 so as to conduct a precise processing procedure. Further, through the second height adjusting unit 61 and the third height adjusting unit 62 with different moving routes, the processing unit 63 can be adjusted by a larger range and more rapidly by the second height adjusting unit 61, and adjusted by a smaller range by the third height adjusting unit 62.

Further, with the seat mechanism 4 operable to angularly move the microscopic image capturing mechanism 5 and the processing mechanism 6, the processing unit 63 can be adjusted to be inclined relative to the biosamples 901 in the sample container 900 by different inclined angles. Furthermore, with the movement adjusting mechanism 3 for adjusting the microscopic image capturing mechanism 5 and the processing mechanism 6 in both the first direction 801 and the second direction 802, a sampling operation on a plurality of sample containers 900 can be conveniently performed.

Moreover, with the movement adjusting mechanism 3, the seat mechanism 4, the microscopic image capturing mechanism 5 and the processing mechanism 6, the microscopic operating device is suitable for intelligent control with automation equipment.

While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
