[0003] Since the temperature of the ultrasonic knife head is required to be lower than 38°C during use, it is necessary to cool the ultrasonic knife head. The cooling method used in the prior art is to use water droplets to cool the ultrasonic knife head. Although it can reach For the purpose of cooling the head of the ultrasonic scalpel, but the water droplets will flow into the incision of the patient, resulting in unclear operation field, which will affect the doctor's smooth operation for the patient; secondly, the ultrasonic osteotome in the prior art directly uses the mains power supply to carry out the operation. power supply, it is difficult to ensure that the ultrasonic bone knife can still be used normally during a power outage; in addition, the ultrasonic bone knife in the prior art is not easy to store, resulting in inconvenient use, and is also easy to be damaged due to contact or impact of the knife head

Embodiment 1
[0044] A kind of ultrasonic bone knife for spinal surgery, such as figure 1 and 4 As shown, it includes a housing 1, a liquid cooling mechanism 3, an ultrasonic bone knife body 2, a power supply structure 4, and a storage mechanism 5. The liquid cooling mechanism 3 is fixedly installed inside the housing 1, and the ultrasonic bone knife body 2 is set Outside the shell 1, and the ultrasonic bone knife body 2 communicates with the liquid cooling mechanism 3, the power supply structure 4 is fixedly installed inside the shell 1, and the power supply structure 4 is respectively connected to the The ultrasonic osteotome body 2 is electrically connected to the liquid cooling mechanism 3 , the storage mechanism 5 is fixedly installed on the outer side of the housing 1 , and the storage mechanism 5 is used to store the ultrasonic osteotome body 2 . In the above technical solution, the ultrasonic osteotome body 2 is used to perform surgery on patients, specifically cutting bones; the l...

[0056] The difference from Example 1 is that the surface of the housing 1 is also provided with a protective layer, and the protective layer is prepared by the following method:
[0057] Take the following raw materials and weigh them by weight: 14-19 parts of epoxy resin, 7-10 parts of titanium dioxide powder, 10-12 parts of nano-silver powder, 8-10 parts of mica powder, 10-15 parts of acrylic emulsion, 6-8 parts of melamine resin 2-4 parts of alcohol ester twelve, 2-4 parts of ferric chloride, 1-3 parts of high-carbon alcohol fatty acid ester complex and 40-50 parts of water;
[0058] S1. Add the weighed acrylic emulsion, melamine resin, alcohol ester twelve, ferric chloride, high-carbon alcohol fatty acid ester compound and water into the mixer and stir for 20-30min at a stirring speed of 600-900r / min , making a mixed solution;
[0059] S2, adding epoxy resin, titanium dioxide powder, nano-silver powder, and mica powder into a pulverizer for pulverization until the particl...

Abstract
The invention discloses an ultrasonic bone knife for spinal surgery, which comprises a shell, a liquid cooling mechanism, an ultrasonic bone knife body, a power supply structure and a storage mechanism, the liquid cooling mechanism is fixedly installed inside the shell, and the ultrasonic bone knife The main body is arranged outside the shell, and the ultrasonic bone knife body communicates with the liquid cooling mechanism, the power supply structure is fixedly installed inside the shell, and the power supply structure is respectively connected to the ultrasonic bone knife The body is electrically connected with the liquid cooling mechanism. In the present invention, it can prevent the cooling liquid from flowing in the incision of the patient, thereby effectively ensuring the clear operation field, and further ensuring that the doctor can perform the operation on the patient smoothly. Instead of directly using the mains for power supply, it can effectively ensure the ultrasonic The bone knife can still be used normally, and it is more convenient to store, thereby making it more convenient to use, and can also effectively prevent the knife head from being damaged due to contact or impact.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic osteotome for spinal surgery. Background technique [0002] Ultrasonic osteotome is an innovative technology with many characteristics and advantages that traditional manual and electric orthopedic surgical instruments cannot match. It uses high-intensity focused ultrasound technology to convert electrical energy into mechanical energy through a transducer, and through high-frequency ultrasonic vibration, the water in the contacted tissue cells is vaporized, and the hydrogen bond of the protein is broken, so that the bone tissue that needs to be cut during the operation is completely cut. destroy. When in use, the temperature of the ultrasonic knife head is lower than 38°C, and the surrounding propagation distance is less than 200 microns. Since the high-intensity focused ultrasonic wave only has a destructive effect on bone tissue with a specific hard...
