Description

Technical Field

[0002] Embedding is a method for preparing immobilized enzymes or immobilized cells, which is to embed enzymes or cells in a solidifiable carrier. For example, the enzyme is encapsulated in a polymer gel such as polyacrylamide gel, or in a semipermeable polymer membrane such as nitrocellulose. The former is embedded in a lattice type, and the latter is embedded in a microcapsule type. The embedding method is commonly used for the immobilization of microorganisms, animals and plant cells. The gel embedding method is the most widely used cell immobilization method. Embedding is an important step in pathological technical work, which is to place the fixed, dehydrated, transparent and wax-impregnated specimens with tweezers in an embedding frame filled with melted paraffin. After the paraffin solidifies, the tissue will obtain a certain hardness and toughness for easy slicing.

[0003] However, such paraffin embedding forceps in the prior art have a heating requirement, the purpose of which is to slightly heat the tweezers so that when clamping the paraffin package, the paraffin package can be slightly melted to prevent the smooth surface of the paraffin package from being difficult to clamp, so as to improve the clamping efficiency, and also prevent the clamped tissue from adhering to the tweezers. Such paraffin embedding forceps in the prior art, such as the Chinese patent application number CN202010526256.1, a paraffin tissue embedding forceps that can emit light and heat, has an added heating module when in use, which can heat the front end of the tweezers to play a role of heating and clamping, but the entire heating part is exposed to the outside regardless of whether it is clamping or not. In this way, when the device is not in use, the head of the tweezers is exposed to the outside, and there is a risk of burns. Therefore, in view of this problem, a paraffin embedding forceps with a heating function is needed to be improved. Utility Model Content

[0022] The outer surface of the heat insulating sleeve 8 is provided with a groove 12, and the friction force of the outer surface of the heat insulating sleeve 8 can be increased by the groove 12, so as to facilitate the user to hold and use the device;

[0023] A control box 13 is fixedly provided at one end of the connecting wire 7. The heating wire 5 and the thermistor 6 are electrically connected to the control box 13 through the connecting wire 7. The operation of the heating wire 5 can be controlled by the control box 13, and the operating temperature of the heating wire 5 can be monitored in real time by the thermistor 6, so as to facilitate the temperature control of the control box 13; so as to ensure that the heating temperature of the heating wire 5 is maintained at a suitable temperature;

At the same time, the heating head cover of the tweezers 1 can be isolated when it is temporarily placed or not in use, thereby effectively improving the safety of the device when in use to prevent others from accidentally touching it. The adjustment principle of the device is that the heat insulation sleeve 8 of the device is a flexible rubber insulation material. When its position needs to be adjusted, the staff can always hold it with their hands. At the position of the elastic connector 2, pinch the groove 12 of the insulation sleeve 8, and then pull the insulation sleeve 8 downward or upward, so that the insulation sleeve 8 can be deformed under the action of its own elasticity, and at this time, the arc-shaped buckle is engaged with the slot 9, so that the slot 9 of the insulation sleeve 8 is more easily deformed, so that the insulation sleeve 8 can be pulled to move, and when the insulation sleeve 8 moves to the appropriate slot 9 position, the arc-shaped buckle 10 is inserted into another slot 9, so that the insulation sleeve 8 is not easy to move without human operation.

[0027] Working principle: When using the device, the plug 14 is connected to the power supply, and then the power supply is used to power the heating wire 5, so that the heating head 3 can be heated to play the role of heating and clamping the paraffin package; at this time, the working temperature of the heating wire 5 is monitored in real time by the thermistor 6 to facilitate the temperature control of the control box 13; to ensure that the heating temperature of the heating wire 5 is maintained at a suitable temperature, and when the thermistor 6 feeds back the temperature information to the control box 13, the control box 13 can display the temperature of the heating head 3 at this time through the display screen 11; to facilitate the use of the staff, and to further ensure the safety of the use of the device, to prevent the staff from touching the heating head 3 without knowing the temperature;

[0028] When the device is in use, the position of the heat-insulating sleeve 8 can be adjusted by snapping the arc-shaped buckle 10 into different slots 9, so as to adapt to the holding needs of different users. At the same time, when the power is temporarily placed without being turned off, or when the heating head 3 is not in use and has not yet cooled to room temperature, the heating head 3 of the tweezers 1 can be isolated, thereby effectively improving the safety of the device when in use to prevent others from accidentally touching it.
