Scalpel rod structure and ultrasonic scalpel including scalpel rod structure

Abstract

The invention provides a scalpel rod structure and an ultrasonic scalpel including the scalpel rod structure. The length of the scalpel rod structure is 343.5 mm. The scalpel rod structure comprises atail part, a coupling area I, a coarse-fine alternate area and a coupling area II, wherein the tail part, the coupling area I, the coarse-fine alternate area and the coupling area II are sequentiallyconnected. The coarse-fine alternate area is formed by alternately arranging cylinders with different diameters. The tail part is a cylinder body. The coupling area I is a cylinder body. The couplingarea II is a cylinder body. The coarse-fine alternate area is provided with six fine structures and six coarse structures. All the coarse structures have the same diameter. All the fine structures have the same diameter, and the diameter difference between the coarse structures and the fine structures is less than 0.3mm. The coupling area I is connected with the fine structures in the coarse-finealternate area, and the coupling area II is connected with the coarse structures in the coarse-fine alternate area. The ultrasonic scalpel can work safely in a fixed frequency range without causing difficulty in operation or unsafe use due to frequency drift; and when an ultrasound wave passes through the coarse-fine alternate structure, the amplitude of an ultrasonic scalpel head can be enhanced, and the electrical energy conversion efficiency can be improved.

Description

Technical field [0001] The invention belongs to the field of ultrasonic medical treatment, and in particular relates to a knife bar structure and an ultrasonic scalpel containing the knife bar structure. Background technique [0002] In clinical practice, ultrasonic scalpel has very good effects, such as: neat cutting edge, fast hemostasis, small thermal damage range, less smoke, etc. It has now become an important tool for clinical surgery. With the continuous development of technology, ultrasound The requirements for scalpels are also getting higher and higher. These problems are mainly manifested in the fact that ultrasonic scalpels are prone to external interference and load effects during the work process, and it is easy to change the vibration mode from pure longitudinal vibration to other vibrations.

Problems solved by technology

[0002] Clinically, the ultrasonic scalpel has very good effects, such as: neat knife edge, fast hemostasis, small thermal damage range, less smoke, etc., and has now become an important tool for clinical surgery. The requirements for the scalpel are getting higher and higher. These problems are mainly manifested in the fact that the ultrasonic scalpel is easy to receive external interference and load during the working process, and it is easy to change its vibration mode from pure longitudinal vibration to other vibrations. mode, thus affecting the working efficiency and cutting ability of the ultrasonic scalpel, thus causing certain difficulties for clinicians in the precise control of the scalpel, which in turn affects the surgical effect and even endangers the personal safety of patients. The traditional ultrasonic scalpel cannot solve the problem gradually. these needs
