Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of medical apparatus and instruments, and relates to an auxiliary device, in particular to a maintenance device for an ultrasonic scalpel, and more particularly to a cleaning device for an ultrasonic hemostatic scalpel head of the ultrasonic scalpel. BACKGROUND
[0002] An ultrasonic scalpel (also referred to as an ultrasonic hemostatic scalpel) is a surgical instrument that cuts and separates biological tissues by high-speed vibration. The ultrasonic scalpel system comprises three main components: an ultrasonic excitation power supply (main generator), a driving handle (ultrasonic transducer), and an ultrasonic hemostatic scalpel (instrument). The main function of the ultrasonic excitation power supply is to generate high-frequency and controllable electric power, and during the tissue cutting process, the power can be adjusted according to the coagulation speed and cutting speed. The function of the driving handle is to convert high-frequency electric energy into ultrasonic mechanical (vibration) energy. A sandwich piezoelectric transducer is usually used to realize the conversion of electric energy into mechanical energy. Ultrasonic vibration is transmitted to the blade at the scalpel head through the scalpel rod, and the blade radiates acoustic energy from the scalpel head. The blade can be in the form of a thin sheet, an arc, a sphere, or a pair of scissors, etc., to meet the needs of different operations. The ultrasonic scalpel can also be designed to suck out the cut or emulsified tissues from the body using negative pressure while cutting, realizing the integration of multiple functions.
[0003] The ultrasonic hemostatic scalpel head is arranged at the end of the scalpel rod and comprises a blade and a clamping piece, and the blade and the clamping piece together form a jaw. The scalpel rod comprises a sleeve, an axially movable tubular connecting rod arranged in the sleeve, and a central rod arranged in the tubular connecting rod and axially movable. The blade is connected to the central rod, and the clamping piece is hingedly connected to the sleeve and the tubular connecting rod, respectively, and the three components form a slider-rocker mechanism. Axial movement of the tubular connecting rod drives the clamping piece to swing, so that the jaw formed by the clamping piece and the blade is opened or closed.
[0004] During the operation, the scalpel head contacts human tissues and tissue fluids, and the high temperature generated during the cutting work of the scalpel head causes the human tissues and tissue fluids to stick to the scalpel head, resulting in contamination of the scalpel head. Therefore, the scalpel head needs to be cleaned frequently during the operation. Since the ultrasonic hemostatic scalpel head cannot be in contact with hard objects, the current method for cleaning the scalpel head is to use alcohol cotton to wipe it by hand. This cleaning method has the following problems. On the one hand, the soft alcohol cotton cannot easily remove the human tissues and tissue fluids that stick to the scalpel head, and the cleaning effect is not good, which affects the quality of the surgical incision. On the other hand, manual cleaning takes a long time, which seriously affects the progress of the operation and endangers the safety of the patient, because the operation needs to be completed as soon as possible to ensure the safety of the patient.
