Description

Technical Field

[0001] The utility model relates to a cryostat microtome, in particular to a cryostat microtome. Background Art

[0002] A cryostat microtome refers to an instrument that can quickly produce tissue sections for observation by making tissue reach a certain hardness at low temperature. A cryostat microtome consists of a sectioning device and a refrigeration system, and usually consists of a main body (devices such as a freezing box, a sample head, a quick-freezing table, etc.), a tool rest and a blade to form a complete cryostat microtome system.

[0003] When a cryostat microtome is in use, for convenient observation, a slidable glass door is generally provided at the freezing box. When installing a specimen, the glass door needs to be opened for operation. Usually, the opening time of the glass door is short. However, the inventor found during actual operation that during the sectioning of the specimen, in order to ensure that the thin slices cut during continuous sectioning do not wrinkle, a sweeping operation is usually required. During the sweeping operation, the staff's arm needs to reach into the interior of the cryostat microtome for operation, and at this time the glass door is in an open state;

[0004] When the above-mentioned glass door is opened, the cold air inside the cryostat microtome will dissipate. On the one hand, it will cause the temperature inside the cryostat microtome to rise. On the other hand, the external hot air will enter the equipment interior, and the hot air and cold air will exchange, generating an air flow inside the cryostat microtome, which is likely to blow the thin slices and reduce the section quality. At the same time, the external hot air contains more water vapor. After pre-cooling and liquefaction, it will cause liquid water to adhere to the inside of the cryostat microtome, further deteriorating the sectioning environment inside the cryostat microtome. Therefore, a cryostat microtome is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0005] Based on the above description, the utility model provides a cryostat microtome to solve the problem that hot air is likely to enter the equipment interior during operations such as sweeping of the cryostat microtome.

[0033] Please refer to Figures 1 - 3 , a cryostat, comprising:

[0034] The cryostat main body 1; and

[0035] A glass door 2, which is arranged inside the cryostat main body 1 and includes a mounting hole 22. The glass door 2 includes a door panel 21, and the upper surface of the door panel 21 is provided with the mounting hole 22;

[0036] Based on the above, the door panel 21 is the prior art of the cryostat main body 1, and the mounting hole 22 serves to provide an installation space for the connecting member 3.

[0037] Such as Figure 2 and Figure 6 shown, a connecting member 3, which is arranged inside the mounting hole 22 and includes a clamping hole 33 and a transverse groove 34;

[0038] The connecting member 3 includes a first connecting ring 31 and a second connecting ring 32. The diameters of the opposite sides of the first connecting ring 31 and the second connecting ring 32 are equal to the inner diameter of the mounting hole 22. The diameters of the opposite sides of the first connecting ring 31 and the second connecting ring 32 are greater than the inner diameter of the mounting hole 22. The clamping hole 33 and the transverse groove 34 are sequentially arranged on the upper surfaces of the first connecting ring 31 and the second connecting ring 32, and the clamping hole 33 and the transverse groove 34 communicate with each other;

[0039] Based on the above, the first connecting ring 31 and the second connecting ring 32 are connected by screws. The two connecting rings are respectively arranged on the upper and lower sides of the glass door 2. After the connecting rings are connected, the connecting member 3 is connected to the glass door 2 at this time. At this time, the clamping hole 33 and the transverse groove 34 cooperate with each other to provide a space for the clamping of the replacement part.

[0040] Such as Figure 7 and Figure 8 shown, the operating member 4 includes gloves 41 and goggles 42, and mounting half-rings 5 are arranged on the exteriors of the gloves 41 and the goggles 42;

[0041] Based on the above, the glove 41 enables the operation of the specimen without opening the glass door 2, and the provision of the protective goggles 42 serves as an alternative to the glove 41. When the glove 41 is not needed, the protective goggles 42 facilitate the sliding opening of the glass door 2 more conveniently.

[0042] As Figure 4 , Figure 5 , Figures 7 - 10 shown, the mounting half-ring 5 is installed outside the operating member 4 and inside the connecting member 3. The mounting half-ring 5 includes a ring plate 51. Elastic sheet grooves 53 are provided on opposite sides of the ring plate 51. The elastic sheet grooves 53 are distributed at equal intervals in a circular shape. Elastic sheets 6 are provided inside the elastic sheet grooves 53. The elastic sheets 6 extend outside the elastic sheet grooves 53. Clamping blocks 52 are provided on the outer surface of the ring plate 51. The clamping blocks 52 are distributed at equal intervals in a circular shape along the outer circle of the ring plate 51. The clamping blocks 52 extend into the transverse groove 34.

[0043] The elastic sheet 6 is provided inside the mounting half-ring 5 and is in contact with the inner wall of the connecting member 3.

[0044] Based on the above, the two mounting half-rings 5 are connected to each other by screws. Before connection, the elastic sheets 6 can be placed inside the elastic sheet grooves 53, thus fixing the elastic sheets 6. After the two mounting half-rings 5 are connected, the operating member 4 can be clamped to the connecting member 3 through the mounting half-ring 5. During the clamping process, the elastic sheets 6 will undergo elastic deformation to generate a reverse elastic force, making the installation tight enough after installation.

[0045] In actual use of this embodiment, by respectively arranging the first connection ring 31 and the second connection ring 32 on the upper and lower sides of the glass door 2, after the connecting member 3 is inserted into the installation hole 22;

[0046] the replacement part can be rotated after passing through the clamping hole 33, and then the replacement part is clamped into the transverse groove 34. During this process, the elastic sheets 6 are stressed and elastically deformed. Under the action of the elastic force, the elastic sheets 6 are closely attached to the inner wall of the connecting member 3, realizing the installation of the replacement part. If disassembly is required, reverse operation can be performed;

[0047] By providing the glove 41, the replacement part can perform the sweeping operation without opening the glass door 2. At this time, the glass door 2 is in a closed state, thus avoiding the negative impacts caused by opening the glass door 2 for a long time;

[0048] When the glove 41 is not needed for operation, the replacement part can be disassembled and then replaced with a replacement part with protective goggles 42. The advantage of the provision of the protective goggles 42 compared to the glove 41 is that the sliding of the glass door 2 will not affect the operation of the internal components of this cryostat microtome;

[0049] Compared with traditional cryotomes, this cryotome has replacement parts in two forms. Through the setting of the replacement parts, specimens can be operated without opening the glass door 2.

[0050] 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 within the protection scope of the present invention.
