Problems solved by technology

[0005] However, the current automatic slide changing devices all simulate the process of changing slides manually. The scanned pathological slides are removed, and then the unscanned pathological slides are put into the instrument. The whole process requires four separate serial The action can only be completed, and it takes a long time to change the film
For batch-type pathological slide scanning instruments, long-term slide change actions will lead to low slide scanning efficiency, and complex actions will increase mechanical damage and reduce system stability. Therefore, a simple and capable A device for quickly changing pathological slide samples to improve the operating efficiency of fully automatic slide scanners

Embodiment 1

[0031] See figure 1 , this embodiment includes a feed drive mechanism 60 , a double-clamp slide holder 70 and a slide holder 20 .

[0032] The feed drive mechanism 60 is used to fix the double-clamping slide holder 70 and drive the double-clamping slide holder 70 to move relative to the slide holder 20;

[0033] In this example, see figure 2 , double-clamp slide clamp 70, used for clamping and transporting slides, including a longitudinal displacement mechanism 701, a clamp base 702 and a movable clamping piece 705; one side of the clamp base 702 is provided with an upper clamping plate 703 and a lower Clamping plate 704; the longitudinal movement mechanism 701 is fixed on the clamp base 702, and one end of the longitudinal movement mechanism 701 is provided with a movable clamping piece 705, and the movable clamping piece 705 is positioned between the upper clamping plate 703 and the lower clamping plate 704. The vertical up and down movement of the displacement mechanism ...

Embodiment 2

[0047] See Figure 4 On the basis of Embodiment 1, the present invention further adds a lifting mechanism 50, and the driving mechanism 60 and the double-clamping slide clamp 70 are installed on the lifting mechanism together to drive the feed driving mechanism 60 and the double-clamping mechanism. The holding type slide holder 70 moves longitudinally, so the height of the double holding type slide holder 70 can be flexibly adjusted to suit the height of the slide storage box or the slide holder 20

[0048] The lifting mechanism 50 is composed of a stepping motor screw mandrel slide table in this example. When the stepping motor is fed, the stepping motor drives the screw mandrel to rotate and drives the slide table to move longitudinally.

Embodiment 3

[0050] See Figure 5 On the basis of Example 2, a rotating mechanism 10 is further added, and the rotating mechanism 10 is installed at the bottom of the lifting mechanism for driving the feed drive mechanism 60 and the double-clamping slide holder 70 to rotate in a plane. In practical applications, the slide storage box and the slide holder 20 are probably not in the same orientation, so through the flexible rotation of the rotating mechanism, the double-clamping slide holder 70 can be aligned with the slide storage box when taking the slide, When sending the slides, the double clamping slide holder 70 rotates an angle to align with the slide holder 20 .

[0051] In this example, the rotating mechanism 10 is composed of a stepping motor and a worm gear structure. When the stepping motor is fed, the rotation of the stepping motor drives the worm gear structure to rotate.

Abstract

The present invention discloses a pathological slide replacement device, comprising a feeding drive mechanism, a double-clamping slide fixture, and a slide holder; wherein the feeding drive mechanismis used to drive the double-clamping slide fixture to perform feeding movement relative to the slide holder; the double-clamping slide fixture is used to hold a carrier slide, forming upper and lowerclamping slots that can be activated asynchronously; the slide holder is used to carry a slide during imaging process and is provided with two steps at ends. An upper clamping slot is activated first,holds the slide to be imaged to a slide slot, and a first step presses and fixes the slide; then a lower clamping slot is activated, and the lower clamping slot holds the imaged slide to exit the slot; then the first step releases the slide to be imaged, and the slide to be imaged falls into bottom of the slide slot; and finally, a second step presses and fixes the slide and waits for imaging. The process of taking the slide and the process of feeding the slide are completed in a same action, and the serial four-step action process is turned into two-step operation of one release and one take, greatly improving efficiency of continuous slide scanning.

Description

technical field [0001] The invention relates to the field of biomedical instrument design, and more specifically, to the field of an automatic slide changing device in a pathological slide scanner. Background technique [0002] At present, the traditional pathological examination in clinical practice uses optical microscope and human eyeglass examination, which heavily depends on the experience and professional level of a single doctor, and there is a certain probability of false detection. Not only is the detection efficiency low, but the storage and carrying of tissue samples are also extremely unchanged. , creating great obstacles to pathology teaching and remote consultation. At the same time, due to the needs of follow-up visits and teaching, hospitals need to preserve pathological slides for several years or even decades. With the increase in the number of pathological slides, the storage and management costs of pathological slides are also getting higher and higher. ...
