Abstract:
A suction device comprises a first element, a second element, and an intermediate element. The first element comprises a first control volume having a first pressure. The second element comprises a second control volume having a second pressure. The intermediate element is controlled by the first pressure of the first control volume of the first element and the second pressure of the second control volume of the second element. When the first control volume of the first element is varied, the varied first control volume of the first element can substantially have the first pressure under automatic pressure compensation by the second pressure of the second control volume of the second element via the intermediate element.
Abstract:
A selecting apparatus for selecting cell/tissue mass includes a base, a feeding mechanism and a dividing mechanism. The base has a platform for placing the cell/tissue mass. The feeding mechanism, disposed on the base, moves relative to the platform. The dividing mechanism, disposed on the feeding mechanism, includes a first cutting set and a second cutting set connected therewith. The second cutting set reciprocally moves between a first position and a second position, toward the first cutting set. The feeding mechanism moves the dividing mechanism above the platform, aligning the dividing mechanism with a portion of the cell/tissue mass, and moves the first cutting set toward the cell/tissue mass, cutting into the portion of the cell/tissue mass. The second cutting set moves from the first position to the second position, limiting the portion of the cell/tissue mass between the first cutting set and the second cutting set.
Abstract:
A cell colonies dissecting and transplanting apparatus comprises: a base, a platform, a feeding mechanism having at least three axis feeding means, a movable holder, a cutting means, a transplanting means, and a CCD image capturing means. The platform having the CCD image capturing means therebottom is disposed onto the base, and on the platform is defined with the holder for receiving a plurality of loading trays, so as to the original cell colonies and a plurality of media boards of subculture can be placed on the loading trays of holder, the holder can displace from a first axis feeding means and a second axis feeding means of feeding mechanism to moveably align with a first axis and a second axis. In addition, the cutting means and the transplanting means respectively capable of vertically move along a third axis feeding means of feeding mechanism are arranged onto the base, wherein the cutting means is provided with an array of invertable blades, and the transplanting means is defined with a bent capture needle for capturing the cell masses, whereby enabling to use operational analysis of controller to precisely cut, capture and pickedly place the original cell colonies.

Abstract:
A micro pump device comprises a structure of chamber with centrally symmetric crossection, a needle compression unit and a traditional fluid extraction and injection unit. The needle compression unit combines with the chamber. The symmetric crossection is utilized to generate fine change in volume for fluid withdraw or discharge. It can be applied as a basic element to products requiring fine fluid withdraw and discharge resolution.
Abstract:
A dissection device for organisms includes a table bearing an organism and at least one blade lifted or lowered to approach the table. The blade includes a connecting portion, a cutting portion having a curved edge, and a neck portion connecting the connecting portion and the cutting portion. When the blade is lowered to contact the table, the cutting portion is rotated with respect to the neck portion to have rolling contact with the table from a first point to a second point of the edge.
Abstract:
A device and method for capturing a biological tissue, comprises cutting a minute biological cellular tissue using a contactless cutting apparatus, wherein, by inverting a biological tissue slide provided with a sample thereon, and after cutting a cellular tissue profile using said contactless cutting apparatus, an impact lever moving mechanism applies from up to down a proper impact force or vibration force onto the target area thus cut, and thereby render said cellular tissue specimen thus captured dropping exactly through a tissue sampling hole into a sampling mortar located therebelow so as to achieve the object of capturing the desired minute biological cellular tissue.

Abstract:
A dissection apparatus is disclosed. The dissection apparatus includes a supporting mechanism, a holder, a driving element rotating the holder, a cam fixed to the supporting mechanism, a first sliding element, a second sliding element, a dissecting device disposed on the first sliding element, an aspirating device disposed on the second sliding element. When the holder rotates to move the dissecting device from a first idle position to an operating position, the first sliding element is lowered by the guide of the cam enabling the aspirating device to move from the operating position to a second idle position. When the holder rotates to move the aspirating device from the second idle position to the operating position, the guide of the cam lowers the second sliding element, thus, allowing the dissecting device is able to move from the operating position to the first idle position.
Abstract:
An aspiration device for cells or tissues loaded on a container includes a tubular body, a scraper disposed on the tubular body. The scraper scrapes cells or tissues from the container, and the scraped cells or tissues are suctioned into the tubular body. The scraper includes a connecting portion connected to the tubular body, an elastic portion connected to the connecting portion, and a scraping end connected to the elastic portion. When the scraper scrapes the cells or the tissues, the elastic portion deforms elastically to enable the scraping end to abut the surface of the container, thus, the cells or tissues are scraped.
