Description

Technical Field

[0001] The present application relates to the technical field of cell specimen fixation and detection, and in particular to a device for fixing and detecting specimens after neck dissection. Background Art

[0002] During oral cancer surgery, the lymph nodes, adipose tissue, and possibly involved lymphatic vessels in the neck area are surgically removed en bloc to completely eliminate potential latent cancer cells and reduce the risk of cancer cell metastasis through the lymph nodes. After resection, the lymphatic tissue is sampled, fixed, and detected for pathological analysis to provide ideas for subsequent treatment. Lymphocyte fixation methods usually involve immersing the specimen in appropriate chemical reagents, such as formaldehyde and ethanol. These reagents can coagulate, precipitate, or denature the proteins in the cells, thereby maintaining the cell morphology and antigenicity. Lymphocyte detection is usually performed through a series of experimental methods, including but not limited to flow cytometry, immunohistochemistry, and microscopic observation. These methods can qualitatively and quantitatively analyze the number, type, proportion, and functional status of lymphocytes.

[0003] The existing fixation and detection device can only fix one lymphatic specimen at a time. When comparing and detecting multiple specimens, they need to be fixed and removed one by one, which is not only time-consuming but also requires alignment with the observation microscope, making it not very practical. Utility Model Content

[0004] The purpose of the present application is to provide a specimen fixation and detection device after neck lymph node dissection, which solves the problem that the existing fixation and detection device proposed in the background art can only fix one lymph specimen at a time, and needs to fix and remove multiple specimens one by one when performing comparative detection, which is not only time-consuming but also requires alignment with the observation microscope, making it not very practical.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a device for fixing and detecting specimens after cervical lymph node dissection, comprising a workbench, a slide plate, a light groove and a specimen placement plate, a light groove being provided at the top center of the workbench, and two parallel adjustment grooves being provided on the workbench surface on the left and right sides of the light groove, the bottom protrusion of the slide plate being connected to the inner side of the adjustment groove for transverse sliding, and a slider being connected to the inner side of the top slide of the slide plate for transverse sliding, the top of the slider being fixedly connected to a round rod, circular holes of the same size as the round rod being provided at both ends of the surface of the specimen placement plate and being movably plugged into the round rod, a storage groove being provided on the front surface of the workbench, a plurality of groups of brackets being fixedly connected to the inner wall surface of the storage groove, and a recovery dish being movably placed on the inner bottom of the storage groove.

[0006] In this technical solution, the two end surfaces of the specimen placement plate are inserted into the round rod, and then slid down and fit into the slider, which is relatively convenient to install. Several specimens are arranged on the surface of the specimen placement plate and observed by the microscope structure above. When it is necessary to switch specimens, it is only necessary to slide the slider to move the specimen placement plate to quickly switch specimens, and the adjustment groove can adjust the position of the entire slide plate, which is convenient for aligning the microscope and improving the detection efficiency of the device. At the same time, the specimen placement plate can be quickly replaced and recovered through the storage slot, bracket and recovery dish. The specimen placement plate to be detected is placed in advance on the bracket in the storage slot. When replacing the specimen placement plate, the specimen placement plate prepared on the bracket is taken out and installed on the slider. The replaced specimen is placed in the recovery dish with disinfectant liquid for recovery, thereby improving the specimen detection efficiency and recovery efficiency of the device.

[0007] As an optional solution of the technical solution of the present application, a light bulb is fixedly installed on the inner bottom of the light trough, and a light-transmitting glass is fixedly connected to the top opening of the light trough.

[0008] As an optional solution of the technical solution of the present application, the surface of the slider on one side of the round rod is threadedly connected to a limiting bolt, and the top edges of the slide plates on both sides of the light groove are threadedly connected to extrusion bolts.

[0009] As an optional solution of the technical solution of the present application, a movable plate is movably connected to the inner bottom edge of the storage tank.

[0010] As an optional solution of the technical solution of the present application, a microscope structure is fixedly connected to the workbench surface on the side of the light trough away from the storage trough.

[0011] As an optional solution of the technical solution of the present application, the two ends of the specimen placement plate are in a horizontal state when located on the surface of the slider.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This application uses an adjustment slot, a slide plate, a slider and a specimen placement plate to facilitate quick switching of specimens. The two end surfaces of the specimen placement plate are inserted into the round rod, and then slid down to fit the slider. The installation is relatively convenient. Several specimens are arranged on the surface of the specimen placement plate and observed by the microscope structure above. When the specimen needs to be switched, only the slider needs to be moved to move the specimen placement plate to quickly switch the specimen. The adjustment slot can adjust the position of the entire slide plate, thereby facilitating alignment of the microscope and improving the detection efficiency of the device.

[0014] 2. This application uses a storage tank, a bracket and a recovery dish to facilitate the quick replacement and recovery of specimen placement plates. The specimen placement plates that are about to be detected are placed in advance on the bracket in the storage tank. When replacing the specimen placement plates, the prepared specimen placement plates on the bracket are taken out and installed on the slider. The replaced ones are placed in a recovery dish with disinfectant liquid for recovery, thereby improving the specimen detection efficiency and recovery efficiency of the device.
