Transducer for ultrasonic scalpel

Abstract

The invention discloses a transducer for an ultrasonic scalpel. The transducer comprises a protective shell, wherein an installation cavity is formed in the protective shell, a first through hole is formed in the left side surface of the protective shell, a collector is fixedly connected to the inner side wall of the protective shell, the left end of the collector communicates with the right sidesurface of the first through hole, the scalpel is put on the left side of the protective shell, and the right end of the scalpel extends into the first through hole. The transducer has the advantage of the reasonable design structure, the transducer is connected with a switch, a threaded rod is driven to rotate by rotating a handle, the threaded rod rotates to move through a threaded hole so as todrive a bearing to move, the bearing moves so as to drive a pull plate to move, the pull plate moves so as to drive a connecting plate to move, and the connecting plate moves so as to drive a connecting ring to move, so that the power conversion of the transducer is realized, and the condition that the treatment of a patient is delayed due to the replacement of the scalpel because the operation cannot be performed due to different diseases during operation is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a transducer for an ultrasonic scalpel. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including required computer software; their effects are mainly obtained through physical means, not Acquired through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role. [0003] With the development of science and technology, most of the operations at this stage are bloodless operations. Ultrasonic scalpels are used in bloodless operations, and the current transducers for ultrasonic scalpels cannot adjust the power of the transducers according to the different conditions of the patient. Furthermore, it is necessary to change ...

Problems solved by technology

[0003] With the development of science and technology, most of the operations at this stage are bloodless operations. Ultrasonic scalpels are used in bloodless operations, and the current transducers for ultrasonic scalpels cannot adjust the power of the transducers according to the different conditions of the patient. Furthermore, frequent knife changes are required, and the concentration effect of the sound waves is poor. The poor concentration effect of the sound waves will lead to imperfect operations. Therefore, we propose a transducer for ultrasonic scalpels to solve the above problems.
