Reusable ultrasonic scalpel

Abstract

The invention discloses a reusable ultrasonic scalpel, which comprises a shell, a handle, a scalpel bar component, universal wheels and a moving mechanism, wherein the scalpel bar component runs through the shell; the handle is partially located in the shell and is connected to the scalpel bar component; the universal wheels sleeve the scalpel bar component; the scalpel bar component comprises a core scalpel bar, an inner sleeve and an outer sleeve; the core scalpel bar runs through the inner sleeve; the outer sleeve sleeves outside the inner sleeve; the core scalpel rod is fixed to the handlein an axial direction and gets into limiting connection to the outer sleeve by virtue of a shaft pin in a radial direction; the moving mechanism is arranged in the shell and is connected to the innersleeve; notches are formed in the ends, facing the outer sleeve, of the universal wheels; silica gel plugs are arranged in the notches; a cleaning notch is formed in a connecting portion; and the cleaning notch is sealed by the silica gel plug. Therefore, cleaning and disinfecting can be conducted between the outer sleeve and the inner sleeve, so that the core scalpel bar, the outer sleeve and the inner sleeve can be disinfected, and the scalpel bar component and the ultrasonic scalpel can be repeatedly used; and therefore, waste is avoided.

Description

technical field [0001] The invention relates to the field of reusable ultrasonic surgical knife, in particular to a reusable ultrasonic surgical knife. Background technique [0002] Ultrasonic scalpel is to further amplify the ultrasonic vibration obtained through the piezoelectric converter (the electrical energy is transferred to the piezoelectric converter through the energy generator, and the piezoelectric converter converts the electrical energy into ultrasonic mechanical energy), and is amplified by the head of the knife. An instrument that uses amplified ultrasonic vibrations to cut and coagulate soft tissue. Clinical use of this device can achieve lesion resection at lower temperature and less bleeding. [0003] The cutter bar assembly of the existing ultrasonic scalpel has a core cutter rod, an inner sleeve and an outer sleeve, and the inner sleeve is located between the core cutter rod and the outer sleeve, and can move a certain distance in the axial direction, t...

AI Technical Summary

Problems solved by technology

However, this ultrasonic scalpel has a defect, that is, the ends of the inner sleeve and the outer sleeve are in contact with biological tissue, and the biological tissue will enter the gap between the end of the inner sleeve and the outer sleeve, which is very troublesome to clean. Only the entire ultrasonic scalpel can be discarded

resulting in a greater waste
