Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0030] In addition, in t...

The invention discloses an ultrasonic scalpel with a self-cleaning function and a self-cleaning method thereof. The ultrasonic scalpel comprises a transducer, an amplitude-change pole, a scalpel head, first piezoelectric ceramic and an atomization sheet, wherein one end of the amplitude-change pole is connected with the transducer, the other end of the amplitude-change pole is connected with the scalpel head, a first channel is formed in the amplitude-change pole, the inlet of the first channel is formed in the side wall of the amplitude-change pole, the outlet of the first channel is formed in the end, connected with the scalpel head, of the amplitude-change pole, an atomization groove and an atomization channel are formed in the scalpel head, the area of the atomization groove corresponds to the range of a hole in the atomization sheet, and the first piezoelectric ceramic is arranged between the atomization sheet and the outlet of the first channel. According to the ultrasonic scalpel, when water flows into the first piezoelectric ceramic and the atomization sheet through the first channel, the atomization sheet vibrates at high frequency, the liquid-state water molecule structure is scattered into tiny water mist, and the water mist is sprayed to the scalpel head through the atomization channel, so that the self-cleaning effect is achieved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic scalpel with self-cleaning function and a self-cleaning method thereof. Background technique [0002] With the rapid development of ultrasonic technology, ultrasonic scalpels based on ultrasonic vibration have been widely used in medicine. The ultrasonic scalpel head has no current passing through the human body during work, and is known as a bloodless scalpel. It has the advantages of less bleeding and faster postoperative recovery. The vibration amplitude of the knife head is small, but the vibration frequency is extremely high, so the biological tissue that the knife head can contact is cut quickly without damaging the surrounding tissue. [0003] However, during the use of the ultrasonic scalpel, some biological tissues will inevitably adhere to the cutting surface of the blade. After wiping and cleaning, the larger attachments can be removed, but i...
