Description

Technical Field

[0001] The utility model relates to the technical field of paraffin slicers, in particular to a rotary slicer. Background Art

[0002] In the field of pathology, paraffin pathology sections are an essential pathology sectioning scheme in pathology technology. After the specimen is embedded in a wax block, the wax block needs to be placed on a paraffin slicer and a mechanical device is used to slice the wax block pathologically, usually with a thickness of 3μm. The pathology sections are then placed in a preheated water tank to complete the sectioning, that is, using the surface tension of the hot water to gently stretch the pathology sections to eliminate the wrinkles produced during slicing.

[0003] Currently, after the pathology section is completed, the operator needs to transfer the continuous pathology sections to the preheated water tank with extreme caution. If the operation is not careful, the pathology sections are easily stacked or broken, thereby reducing work efficiency. In addition, the wax block is easily affected by temperature and melts slightly. After long-term pathology sectioning, the continuous cutting friction between the wax block and the blade and the influence of room temperature will affect the temperature of the wax block, causing the shape of the wax block to change slightly.

[0025] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0028] A rotary slicer comprises a slicer body 1, a hand wheel 11 is rotatably mounted on the right side of the slicer body 1, a sample clamping seat 12 is mounted on the front side of the slicer body 1, a mounting seat 13 is arranged at the bottom of the front side of the slicer body 1, and a slice spreading mechanism 2 is arranged on the mounting seat 13. A waste trough 3 is arranged on the front side of the slicer body 1, and the waste trough 3 surrounds the slice spreading mechanism 2.

[0029] The slice spreading mechanism 2 includes a knife holder seat 21 and a preheating water tank 25 arranged in front of the knife holder seat 21. A blade 22, a pre-spreading channel 23 and a conveying water channel 24 are arranged on the top of the knife holder seat 21 from back to front. The sample slices cut by the blade 22 are sequentially sent to the preheating water tank 25 after passing through the pre-spreading channel 23 and the conveying water channel 24.

[0030] The height of the pre-expanding film channel 23 gradually decreases from the back to the front, and the rear end of the pre-expanding film channel 23 matches the blade 22, and the front end of the pre-expanding film channel 23 matches the conveying water channel 24. The top and left and right sides of the pre-expanding film channel 23 are provided with an air guide 231, and the bottom of the pre-expanding film channel 23 is provided with a plurality of air outlet holes 232, and the air outlet holes 232 all blow air to the front and upper side of the pre-expanding film channel 23. The slicing and spreading film mechanism 2 also includes an air outlet pump 26 connected to the air outlet holes 232.

[0031] The airflow forms an air cushion to hold up the sample slices, which can prevent the sample slices from curling up and facilitate the subsequent further unfolding of the sample slices. The airflow blown out of the air outlet 232 forms a stable forward airflow in the air guide cover 231, thereby assisting in pushing the sample slices forward and allowing the sample slices to enter the rear end of the conveying water channel 24.

[0032] The conveying water channel 24 and the preheating water tank 25 are both filled with hot water. The conveying water channel 24 is arranged horizontally, and a small flow nozzle 241 is arranged at the rear bottom of the conveying water channel 24. The small flow nozzle 241 sprays water forward and upward, forming continuous surging waves under the water surface, and forming a water film on the water surface that flows toward the preheating water tank 25. The water film pushes the sample slices floating on the water surface to move toward the preheating water tank 25, and the surging waves vibrate the sample slices on the water surface, further promoting the sample slices to unfold under the surface tension of the hot water. At the same time, a small flow pump 27 is used to prevent the sample slices from being damaged by excessive thrust of the water.

[0033] The top of the conveying water channel 24 is provided with a water inlet interface 242 connected to a small flow nozzle 241, and the bottom of the preheating water tank 25 is provided with a water outlet interface 251. A small flow pump 27 is provided in the tool holder seat 21, and the small flow pump 27 is connected to the water inlet interface 242 and the water outlet interface 251. The small flow pump 27 is used to send water from the water outlet interface 251 to the water inlet interface 242 to realize the recycling of hot water.

[0034] The preheating tank 25 is used to collect the unfolded sample slices and further unfold the incompletely unfolded sample slices. The side wall of the preheating tank 25 is also provided with an ultrasonic generator 252, so as to vibrate the sample slices entering the preheating tank 25, further promote the flattening of the sample slices, and avoid adhesion between adjacent sample slices.

[0035] In addition, a filter 253 is provided in the preheating water tank 25, and the water in the upper part of the preheating water tank 25 enters the lower part after passing through the filter 253. The filter 253 can filter out impurities entering the preheating water tank 25, and prevent impurities from entering the small flow pump 27.

[0036] The utility model integrates the preheating water tank 25 in the paraffin slicer and transports the sample slices through the conveying water channel 24, thereby avoiding the damage of the sample slices caused by manual movement of the sample slices and improving the work efficiency.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
