Abstract
Description
Technical Field
[0001] This utility model belongs to the field of microscope technology, and specifically relates to a microscope electrification device. Background Technology
[0002] In the field of medical pathology diagnosis, pathological slide analysis is a key means of disease diagnosis, especially for tumors. Clinicians need to determine the type of disease by observing the morphology of pathological slides under a microscope, and then formulate targeted treatment plans. Routine pathological slides are thin sections of lesion tissue with a thickness of 3-4 μm, which need to be examined and analyzed area by area by medical staff under a microscope.
[0003] Currently, most microscopes used in hospitals are traditional manual operation types, which have many drawbacks in actual diagnostic work: First, medical staff need to frequently manually perform slide alignment and objective lens focusing operations, and prolonged repetitive actions can easily cause physical fatigue and reduce diagnostic efficiency; Second, medical staff need to keep their eyes close to the eyepiece for observation for a long time, and the strong light from the microscope continuously stimulates the eyes, which can easily induce eye diseases such as conjunctivitis and eye strain, and endanger the vision health of medical staff; Third, if ready-made electric microscopes and matching slide pulling equipment are purchased from outside, not only is the equipment purchase cost high, but the equipment customization, delivery and installation and debugging cycle is also long, making it difficult to quickly meet the immediate needs of hospital pathological diagnosis.
[0004] Based on the aforementioned industry pain points, there is an urgent need to develop a device that can perform low-cost, highly adaptable, and electrically powered retrofits on existing manual microscopes. This device would enable electric focusing, automatic displacement, and digital image display of the microscope without replacing the original microscope body, thus addressing the shortcomings of existing technologies. Utility Model Content
[0005] In view of the problems raised in the background art above, the purpose of this utility model is to provide an electric microscope device.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An electric microscope device includes a microscope module with a slot and a camera mounting mount. A module mounting plate is fixed to the side wall of the working area of the microscope module. An electric Z-axis module is mounted on one side of the microscope module, and the mounting interface of the electric Z-axis module is compatible with the Z-axis mounting interfaces of microscopes from different manufacturers. An X / Y displacement platform module is fixed on the module mounting plate. An electric microscope module is mounted in the slot. A C-mount camera module that is electrically connected to an external computer is mounted on the camera mounting mount. This solution can realize the integrated electric transformation of traditional manual microscopes. It not only meets the transformation needs of microscopes from multiple brands through the adaptable electric Z-axis module, but also realizes the digital display of pathological slide images through the C-mount camera module, effectively avoiding damage to the eyes of medical staff from strong light. At the same time, the electric displacement and focusing structure significantly reduces the operating intensity of medical staff.
[0007] Preferably, the system also includes a slide fixture for supporting and fixing the slide, which is mounted on the X / Y displacement platform module. This solution can provide stable support and positioning for the slide, preventing the slide from shifting or slipping during X / Y displacement, and ensuring the accuracy of the pathological slide observation area.
[0008] Preferably, the electric Z-axis module further includes a motor mounting bracket, a coupling, a cylinder, a rotary motor, and a knob. The cylinder is coupled to the Z-axis mounting interface of the microscope module. The rotary motor is connected to the cylinder through the motor mounting bracket, and its power output shaft is connected to the Z-axis mounting interface via the coupling. The knob is mounted on the manual adjustment end of the rotary motor. This solution realizes the dual functions of electric automatic focusing and manual emergency focusing, which not only meets the automation requirements of routine diagnosis, but also allows focusing to be performed by turning the knob in case of power failure or motor failure, thereby improving the operational reliability and emergency adaptability of the device.
[0009] Preferably, the mounting interface is an adjustable inner diameter elastic metal interface with an anti-slip rubber pad on its inner wall and several threaded adjustment holes on its outer wall. This solution can flexibly adapt to the Z-axis mounting interface specifications of microscopes from different manufacturers through elastic deformation and thread adjustment. The anti-slip rubber pad enhances the stability of the connection, eliminating the need to customize a special Z-axis module for different microscope models, thus greatly reducing the modification cost and adaptation difficulty.
[0010] Preferably, the X / Y displacement platform module includes an a-direction motor module, a b-direction motor module, a circular interface, and a platform base plate. The circular interface is fixed to the bottom of the platform base plate and bolted to the X / Y displacement platform module mounting plate. The a-direction motor module and the b-direction motor module are embedded in the bottom of the platform base plate, and their power output ends are engaged with the slide fixture. This design ensures the stability of the connection between the X / Y displacement platform module and the microscope through bolted connections. At the same time, the engagement of the dual motors with the slide fixture enables flexible movement of the slide in the horizontal two-dimensional direction, thus broadening the observation coverage of pathological sections.
[0011] Preferably, both the a-direction motor module and the b-direction motor module contain stepper motors, which drive the slide fixture to move via lead screws. This solution utilizes the precise stepping characteristics of stepper motors and the stable transmission advantages of lead screws to achieve high-precision displacement control of the slide fixture, which can accurately locate the area to be observed in the pathological section and improve the accuracy and reliability of pathological diagnosis results.
[0012] This invention utilizes a modular design, comprising an electric Z-axis module, an X / Y displacement platform module, an electric objective lens module, and a C-mount camera module. This enables electric focusing, automatic slide displacement, electric objective lens switching, and digital image display of the microscope. The electric Z-axis module connects to the microscope's existing Z-axis interface via an adjustable mounting interface, replacing manual focusing and eliminating fatigue and inefficiency caused by frequent manual operation by medical staff. The X / Y displacement platform module drives precise slide movement, eliminating the tedious manual alignment process. The C-mount camera module transmits microscopic images to a computer screen in real time, allowing medical staff to observe without prolonged close proximity to the eyepiece, effectively avoiding the risk of eye diseases caused by strong light stimulation. The entire device is modular and highly compatible, allowing for low-cost and rapid modification of existing microscopes while retaining the original microscope body. This addresses the industry pain points of high cost and long lead times associated with purchasing electric microscopes, offering practical advantages such as low cost, wide applicability, ease of operation, and improved diagnostic comfort and efficiency.
