Description

Technical Field

[0001] This utility model relates to the field of ultrasonic scalpel technology, and in particular to an ultrasonic scalpel with a negative pressure suction device. Background Technology

[0002] In current minimally invasive surgery procedures, when using an ultrasonic scalpel, the temperature difference between the operating room and the body often causes the scalpel lens to fog up. This requires removing the scalpel and wiping the lens, which prolongs the surgery time. Existing anti-fogging measures involve applying an anti-fogging agent to the lens surface, but this method has a short-term effect and can easily cause chemical pollution inside the body.

[0003] Therefore, in order to solve the existing problems, this application provides an ultrasonic scalpel with a negative pressure suction device, which can effectively prevent lens fogging during surgery and greatly shorten the operation time. Utility Model Content

The coating on the surface of the cover can also prevent the surface of the cover from getting dirty.

[0009] Furthermore, the intelligent temperature control system includes a temperature sensor and a PID controller. The PID controller is connected to the temperature sensor and performs temperature control based on the temperature feedback from the temperature sensor. The intelligent temperature control system intelligently regulates the temperature and airflow inside the enclosure, making it simple to operate and convenient to use.

[0022] The fluid channel 4 includes a suction channel 6 and a gas input channel 7. The suction channel 7 has a flared end inside the cover 3 to enhance suction efficiency. The gas input channel 7 uses a spiral airway, and its surface has spirally arrayed air outlets. The cover 3 is made of transparent material, and its inner wall is covered with a conductive film 8. The cover 3 is detachably connected to the ultrasonic scalpel body 1, and a sealing gasket 9 is provided at the connection point. The sealing gasket is made of medical-grade silicone to ensure that the inside of the cover 3 is under negative pressure.

[0023] The cover 3 is made of transparent AlON ceramic, the thickness of the cover 3 is 1.0-1.5mm, and the light transmittance is ≥92%. The surface of the cover 3 is provided with a nano hydrophobic coating. Using the cover 3 will not affect the clarity of the lens, and it can also prevent the lens from fogging. The coating on the surface of the cover 3 can also prevent the surface of the cover 3 from getting dirty.
