Description

Technical Field

[0002] A paraffin slicing machine is an auxiliary machine that is widely used in medical and biological research to slice tissues embedded in wax. The slices made by the paraffin slicing machine can be used to detect various clinical lesions to ensure that doctors can make more accurate judgments, or to help researchers explore at the tissue and cell levels.

[0003] Common paraffin slicing machines can be manually sliced through a rotating wheel, so they are also called rotary slicing machines by those skilled in the art. The slicing machine includes a rotating handwheel, a sample head base, a tool holder, and a Y-axis driving module. The Y-axis driving module is a structure that controls the sample head base to move towards or away from the tool holder through a motor. This structure mainly plays the role of feeding the paraffin sample.

[0004] When the paraffin slicing machine is actually used, it is necessary to first control the Y-axis driving module to work through a remote control so that the paraffin block is fed to the blade. This feeding amount needs to be observed by the experimenter with the naked eye. At the same time of observation, the handwheel needs to be rotated manually to confirm whether the paraffin contacts the blade. This process of adjusting the distance between the paraffin block and the blade has high requirements for eyesight. If the experimenter is fatigued after working for a long time, the observation difficulty will increase, which will make the time for adjusting the position during paraffin slicing longer, resulting in low efficiency. Therefore, a Y-axis driving module of a rotary slicing machine is proposed to solve the above-mentioned problems. Summary of the Utility Model

The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0030] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprises / comprising" or "has / including" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0031] Please refer to Figure 1 and Figure 2 , the Y-axis drive module of the rotary slicer, comprising:

[0032] A drive mechanism, which includes a base 1, a fixed seat 2, a Y-axis moving block 3, a lifting block 4 and a motor 5. A fixed seat 2 is provided at the top end of the base 1. A motor 5 is provided at one end of the fixed seat 2. The motor 5 is in transmission connection with the Y-axis moving block 3 through a threaded rod. A lifting block 4 is provided on one side of the Y-axis moving block 3. A sample head base 6 is provided at one end of the Y-axis moving block 3;

[0033] Based on the above, the base 1, the fixed seat 2, the Y-axis moving block 3, the lifting block 4 and the motor 5 are all existing structures of the paraffin slicer, that is, the prior art. Among them, the paraffin slicer also includes structures such as a controller, a tool rest, a handwheel and a display screen. These structures do not belong to the technical features protected by this solution, so the specific structures and principles are not described herein.

[0034] As Figures 1-4 shown, an adaptive contact frame, which includes a fixed rod 7, a movable rod 8, an adaptive spring 9, a fixing screw 10 and a movable block 11. Among them,

[0035] The fixed rod 7 is connected to the Y-axis moving block 3 by screws. The fixed rod 7 is a hollow rod. An installation ear is provided at one end of the fixed rod 7. The installation ear is provided at one end of the Y-axis moving block 3 by screws;

[0036] The movable rod 8 includes a rod body 81. The rod body 81 is arranged inside the fixed rod 7. A partition block 82 is provided at one end of the rod body 81. The diameter of the partition block 82 is larger than the inner diameter of the fixed rod 7 near the movable block 11. An adaptive spring 9 is provided between the partition block 82 and the Y-axis moving block 3;

[0037] The movable block 11 is connected to the movable rod 8 through a fixing screw 10. The movable block 11 includes a block body 111. An installation hole 112 is provided on the surface of the block body 111. The fixing screw 10 is arranged inside the installation hole 112. The fixing screw 10 is threadedly connected to the rod body 81. A hinged vertical plate 113 is provided on the upper surface of the block body 111;

[0038] Based on the above, the adaptive contact frame has an adaptive effect. When the Y-axis moving block 3 moves towards the direction close to the movable block 11, the movable block 11 contacts the tool rest. At this time, the distance between the Y-axis moving block 3 and the movable block 11 decreases, that is, the adaptive spring 9 is compressed by force. Under the action of the elastic force, it is ensured that the movable block 11 is closely attached to the tool rest.

[0039] As Figures 4-7 shown, the connecting plate 12 is respectively hinged to the movable block 11 and the hinge frame 13 through screws and nuts. The connecting plate 12 is an H-shaped connecting plate. The connecting plate 12 is hinged to the hinged vertical plate 113 through screws and nuts. The hinge frame 13 includes a hinge frame body 131. The hinge frame body 131 is hinged to the connecting plate 12 through screws and nuts. A fixed vertical plate 132 is provided on one side of the hinge frame body 131;

[0040] The photoelectric sensor 14 is connected to the hinge frame 13 through a screw. The photoelectric sensor 14 includes a sensor main body 141. The sensor main body 141 is connected to the hinge frame 13 through a screw. A limiting plate 142 is provided on the opposite side of the sensor main body 141;

[0041] Based on the above, the movable block 11, the connecting plate 12 and the hinge frame 13 cooperate with each other. By changing the included angle between the connecting plate 12 and the movable block 11 and the included angle between the connecting plate 12 and the hinge frame 13, the device can be adjusted according to the actual situation of the tool rest so that the detection device fits the tool rest. Through the setting of the limiting plate 142, the optical fiber emitted by the sensor main body 141 is in the vertical plane with the blade, so as to ensure that when the paraffin block moves above the blade, it can be sensed in time.

[0042] When this embodiment is actually used, the signal emitted by the photoelectric sensor 14 can be displayed by means of an indicator light or a prompt sound. The indicator light or the prompt sound can be completed through an external LED light or directly through software and then displayed on the display screen. This method only reacts to the signal transmitted by the photoelectric sensor 14, which is an existing and commonly used technology. Therefore, the specific working principle and structure are not described here to remind the experimenter that the paraffin block is in a position where it can be sliced;

[0043] When the paraffin slicing machine is in use, the tool rest is arranged atFigure 1 The position of the middle movable block 11, at this time the adaptive contact frame is closely attached to the tool rest, and the connecting plate 12 and the articulated frame 13 are attached to the surface of the tool rest. At this time, the photoelectric sensor 14 includes a receiver and a transmitter. Since the photoelectric sensor only plays a role of detection, that is, to detect whether the paraffin block reaches the position and has no requirements for other performances, any model of photoelectric sensor can be used. Therefore, the specific model is not described in detail here and is directly above the blade;

[0044] When the paraffin block moves together with the sample head base, that is, when adjusting the distance between the paraffin block and the blade, if the paraffin block moves to the position of the photoelectric sensor 14, the paraffin block blocks the light irradiation, so that the photoelectric sensor 14 transmits a signal to the controller of the paraffin slicer, which is a structure inherent in the paraffin slicer itself and plays the functions of control and signal transmission. Through prompts such as indicator lights, the tester knows that the paraffin block has moved to the appropriate position;

[0045] Compared with the drive module in the traditional paraffin slicer, the Y-axis drive module is provided with a detection mechanism that can detect the position of the paraffin block. By using the photoelectric sensor 14 to replace the human eye observation, it not only has higher efficiency, but also will not have the situation of misreading due to fatigue. Moreover, the detection mechanism can adapt to paraffin blocks of different thicknesses and will not have the situation of inaccurate position adjustment after replacing the paraffin block.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
