If it is not cooled, the life of the syringe will be reduced. Existing methods for cooling syringes mainly use external cooling plates, which have certain requirements on the size of the syringe. Therefore, existing bone cement syringes have the following main problems: (1) It is impossible to directly mix the raw materials of bone cement, which is time-consuming and labor-intensive; (2) The heat is not recovered and used for cooling, resulting in a larger syringe size and inconvenient operation.

[0008] The outer shell of the stirring blade is attached with a temperature difference plate A, and the inner side of the inner sleeve is attached with a temperature difference plate B. The temperature difference plate A and the temperature difference plate B are both provided with semiconductors of two different materials and a metal plate. One end of the semiconductors of two different materials is connected to the metal plate. The two semiconductors on the temperature difference plate A and the two semiconductors on the temperature difference plate B are connected by wires, and one of the wires is connected to the control system.

[0009] A plurality of cooling plates are arranged on the stirring blades, and semiconductors and metal plates of two different materials are arranged on the plurality of cooling plates. The semiconductors of the two different materials on the cooling plates are connected to the metal plates, and the semiconductors on the cooling plates are electrically connected to the control system through wires.

[0010] Multiple groups of telescopic plates are installed on the opposite side of the two groups of follower plates, and the multiple groups of telescopic plates are directly opposite to the sliding groove. The two ends of the multiple groups of telescopic plates are respectively installed on the stirring blade and the follower plate. The telescopic plates are telescopic structures. The multiple groups of telescopic plates block the sliding groove. The telescopic plates follow the movement of the stirring blade to ensure the sealing of the sliding groove and prevent bone cement from falling through the sliding groove.

[0011] A liquid level sensor is installed on the outer shell of the stirring blade, and the liquid level sensor detects the volume of the bone cement and feeds back the data to the control system. The liquid level sensor is located on one side of one of the temperature difference plates A. The barrel is provided with multiple groups, and the multiple groups of barrels are installed on the outer shell. A valve and a displacement sensor are installed in the barrel, and the valve is installed in the middle of the barrel, and the displacement sensor is installed on the lower side of the barrel. The valve and the displacement sensor are both electrically connected to the control system;

[0012] The inner sleeve is mounted on the outer shell, and is provided with a liquid inlet communicating with the interior, and a plurality of the liquid inlets are provided, and the plurality of the liquid inlets are respectively connected to the barrel through pipelines.

[0013] A push plate is installed on the outer shell near the inner sleeve through a spring sliding, and the push plate is connected to a connecting rod through the outer shell, and the connecting rod is connected to the feeding plate. The inner sleeve is connected to the injection tube, and a mark is set on the push plate, and a scale is set on the outer shell near the push plate. The mark on the push plate and the scale on the outer shell can facilitate the staff to inject bone cement.

[0014] A feed port is provided on the shell near the stirring blade, and a switch valve is installed on one side of the feed port. The switch valve is installed on the shell and is electrically connected to the control system. When multiple raw materials are mixed, the switch valve discharges the gas generated by the mixture to the outside.

[0015] A variety of raw materials are put into the feed port, and the staff pulls the driving rod to make the driving rod slide clockwise on the outer shell, and the driving rod drives the rotating plate to rotate a certain angle, and the fixed plate on the rotating plate slides on the guide ring, and one of the fixed plates compresses the energy storage spring, and the toothed structure inside the rotating plate drives the first gear to rotate, and the first gear drives the second gear to rotate, and the second gear transmission shaft rotates, and the transmission shaft drives the universal joint to rotate, and the universal joint drives the stirring blade to rotate, and the stirring blade drives the following plate to rotate, and the stirring blade drives the various raw materials to mix. After that, the staff releases the driving rod, and the energy storage spring is released, and the energy storage spring drives the rotating plate to rotate in the opposite direction, and the toothed structure on the rotating plate drives the first gear to reverse, and the first gear drives the second gear to reverse, and the second gear drives the universal joint to rotate in the opposite direction, and the universal joint drives the stirring blade to rotate in the opposite direction, and the stirring blade drives the various raw materials to mix. By rotating the driving rod forward and reversely, the stirring blade can continue to reverse forward and reverse, thereby achieving the purpose of mixing various raw materials.

[0016] After the various raw materials are mixed, bone cement is formed. The control system opens the valve in the barrel, and the bone cement enters the barrel through the valve and is transported to the inner sleeve through the barrel and the pipeline. The displacement sensor in the barrel feeds back the displacement data to the control system, and the control system then obtains information on whether bone cement has entered the barrel. When the bone cement completely enters the inner sleeve, the displacement sensor feeds back the data to the control system, and the control system closes the valve in the barrel. The buzzer in the control panel alarms to remind the user that the mixing is completed and injection processing is required.

[0017] After the buzzer alarm sounds, the staff pushes the push plate to move, the push plate compresses the spring, the push plate drives the feeding plate to move through the connecting rod, the feeding plate pushes the bone cement in the inner sleeve into the injection tube, and transports it to the injection position through the injection tube to achieve bone cement injection.

[0018] When the stirring blade is rotating, the control system connects the two semiconductors on the cooling plate to the circuit. The semiconductors and metal plates on the cooling plate are the cooling ends in the Peltier effect. The cooling plate cools down various raw materials through the cooling ends. The semiconductors and metal plates on the temperature difference plate A are the hot ends of the Seebeck effect, and the semiconductors and metal plates on the temperature difference plate B are the cold ends of the Seebeck effect. The heat generated by the mixing of various raw materials is transferred to the metal plate on the temperature difference plate A. Since the temperature difference plate A is located on the outer shell of the stirring blade, and the temperature difference plate B is located in the inner sleeve, the temperature of the temperature difference plate A is higher than that of the temperature difference plate B. Therefore, the hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system transmits the current to the two semiconductors in the cooling end after rectification and voltage transformation, so that the cooling plate cools down various raw materials. When the control system detects that the current generated through the hot end and the cold end is small, the cooling end is directly powered by the control system to ensure normal cooling of the cooling plate.

[0019] During the rotation of the stirring blade, the control system energizes multiple sets of electromagnets, and the magnetic material on the transmission shaft rotates with the transmission shaft. When the magnetic material and the electromagnet are close, the electromagnet attracts the magnetic material to move outward, and the magnetic material drives the transmission shaft to move outward. The transmission shaft slides in the sliding groove and compresses the first spring. After that, the magnetic material follows the transmission shaft away from the electromagnet, the first spring is released, and the first spring pushes the transmission shaft to move inward. Therefore, during the rotation of the magnetic material, the stirring blade moves back and forth inward and outward, and the stirring blade vibrates, so that the various raw materials are mixed more thoroughly, thereby improving the mixing effect.

[0020] A driving rod is arranged on the upper side of the rotating plate, and the driving rod is slidably connected to the housing.

[0021] The feed port and the shell are connected in a snap-fit ​​manner, and a handle is installed on the other side of the feed port, and the handle is installed on the shell.

[0022] A control panel is installed on the outer shell, a control system is arranged inside the control panel, and a through groove communicating with the external atmosphere is arranged on the outer shell outside the inner sleeve.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. Compound stirring process makes the bone cement mix more thoroughly. The stirring blade drives the mixing of various raw materials. The driving rod rotates forward and reversely to make the stirring blade continuously rotate forward and reverse to achieve the purpose of mixing various raw materials. The magnetic material on the transmission shaft follows the rotation. When the magnetic material and the electromagnet are close, the electromagnet attracts the magnetic material to move outward, and the magnetic material drives the transmission shaft to move outward. The transmission shaft slides in the sliding groove and compresses the first spring. After that, the magnetic material follows the transmission shaft away from the electromagnet, and the first spring is released. The first spring pushes the transmission shaft to move inward. Therefore, during the rotation of the magnetic material, the stirring blade moves back and forth inward and outward, and the stirring blade vibrates while rotating, forming a compound stirring process to make the mixing of various raw materials more thorough.

[0025] 2. Heat can be recovered and used to cool bone cement. The semiconductor and metal plate on the thermocouple plate B are the cold end of the Seebeck effect. The heat generated by the mixture of multiple raw materials is transferred to the metal plate on the thermocouple plate A. Since the thermocouple plate A is located on the outer shell outside the stirring blade, and the thermocouple plate B is located in the inner sleeve, the temperature of the thermocouple plate A is higher than that of the thermocouple plate B. Therefore, the hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. After rectifying and transforming the current, the control system transmits it to the two semiconductors in the cooling end, so that the cooling plate cools down the various raw materials. When the control system detects that the current generated by the hot end and the cold end is small, the cooling end is directly powered by the control system to ensure the normal cooling of the cooling plate, which can reduce the structural size of the syringe without external cooling.

[0042] The working principle of the present invention is as follows: a variety of raw materials are put into the feed port 14, and the staff member moves the driving rod 2 to make the driving rod 2 slide clockwise on the housing 11, and the driving rod 2 drives the rotating plate 24 to rotate a certain angle, and the fixed plate on the rotating plate 24 slides on the guide ring 21, and one of the fixed plates compresses the energy storage spring 23, and the toothed structure 241 inside the rotating plate 24 drives the first gear 25 to rotate, and the first gear 25 drives the second gear 251 to rotate, and the transmission shaft 26 of the second gear 251 rotates, and the transmission shaft 26 drives the universal joint 22 to rotate, and the universal joint 22 drives the stirring blade 3 to rotate, and the stirring blade 3 The upper and lower groups of follower plates 27 are driven to rotate, and the stirring blades 3 drive the various raw materials to be mixed. After that, the staff loosens the driving rod 2, and the energy storage spring 23 is released. The energy storage spring 23 drives the rotating plate 24 to rotate in the opposite direction. The toothed structure 241 on the rotating plate 24 drives the first gear 25 to reverse, and the first gear 25 drives the second gear 251 to reverse, and the second gear 251 drives the universal joint 22 to rotate in the opposite direction. The universal joint 22 drives the stirring blades 3 to rotate in the opposite direction. The stirring blades 3 drive the various raw materials to be mixed. By driving the driving rod 2 forward and reversely, the stirring blades 3 are continuously reversed forward and reversed to achieve the purpose of mixing various raw materials.

[0043] After the various raw materials are mixed, bone cement is formed. The control system opens the valve in the barrel 16, and the bone cement enters the barrel 16 through the valve and is transported to the inner sleeve 17 through the barrel 16 and the pipeline. The displacement sensor in the barrel 16 feeds back the displacement data to the control system, and the control system then obtains whether bone cement enters the barrel 16. When the bone cement completely enters the inner sleeve 17, the displacement sensor feeds back the data to the control system, and the control system closes the valve in the barrel 16. The buzzer in the control panel 1 alarms to remind the user that the mixing is completed and the injection process needs to be carried out in time.

[0044] After the buzzer alarm, the staff pushes the push plate 15 to move, the push plate 15 compresses the spring, and the push plate 15 drives the feeding plate 28 to move through the connecting rod 151. The feeding plate 28 pushes the bone cement in the inner sleeve 17 into the injection tube 18 and transports it to the injection position through the injection tube 18 to achieve bone cement injection.

[0045] During the rotation of the stirring blade 3, the control system connects the two semiconductors on the cooling plate 42 to the circuit.

The semiconductors and metal plates on the temperature difference plate A4 are the hot ends of the Seebeck effect. The semiconductors and metal plates on the temperature difference plate B41 are the cold ends of the Seebeck effect. The heat generated by the mixing of the various raw materials is transferred to the metal plate on the temperature difference plate A4. Since the temperature difference plate A4 is located on the outer shell 11 of the stirring blade 3, and the temperature difference plate B41 is located in the inner sleeve 17, the temperature of the temperature difference plate A4 is higher than that of the temperature difference plate B41. Therefore, the hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system transmits the current to the two semiconductors in the cooling end after rectification and voltage transformation, so that the cooling plate 42 cools down the various raw materials. When the control system detects that the current generated through the hot end and the cold end is small, the cooling end is directly powered by the control system to ensure the normal cooling of the cooling plate 42.

[0046] During the rotation of the stirring blade 3, the control system energizes multiple groups of electromagnets 29, and the magnetic material on the transmission shaft 26 rotates accordingly. When the magnetic material and the electromagnet 29 are close to each other, the electromagnet 29 attracts the magnetic material to move outward, and the magnetic material drives the transmission shaft 26 to move outward. The transmission shaft 26 slides in the sliding groove and compresses the first spring. After that, the magnetic material follows the transmission shaft 26 away from the electromagnet 29, and the first spring is released. The first spring pushes the transmission shaft 26 to move inward. Therefore, during the rotation of the magnetic material, the stirring blade 3 moves back and forth inward and outward, and the stirring blade 3 vibrates, so that the various raw materials are mixed more thoroughly.
