Reusable ultrasonic scalpel

Abstract

The invention discloses a reusable ultrasonic scalpel. The scalpel comprises a handle assembly and an ultrasonic scalpel rod which is in extending arrangement at the far end of the handle assembly andis used for transmitting ultrasonic mechanical energy, and a sleeve assembly sleeves the outer portion of the ultrasonic scalpel rod and is detachably connected to the handle assembly through a quickconnection mechanism. The reusable ultrasonic scalpel has the main advantages of being reliable in installation, and easy to disassemble, assemble, clean and disinfect, the sleeve assembly as a consumable material is quickly replaced, and other parts can be reused and sterilized through cleaning and high-temperature steam; the material consumption cost of an operation is greatly reduced, the burden of a patient is reduced, and the cross infection risk of the ultrasonic scalpel rod in the use process is also reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an ultrasonic scalpel. Background technique [0002] Ultrasonic scalpel is to further amplify the ultrasonic vibration obtained through the piezoelectric converter (the electrical energy is transmitted 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 scalpel. An instrument that uses amplified ultrasonic vibrations to cut and coagulate soft tissues. Clinical use of this device enables lesion resection at lower temperatures and less bleeding, and ensures minimal lateral thermal damage to tissue. With the popularity of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. [0003] Generally speaking, an ultrasonic scalpel includes a transducer, a handle, and a knife rod assembly arranged at the far e...

AI Technical Summary

Problems solved by technology

After completing one or even several operations, the structure and performance of the ultrasonic scalpel are still intact, but the inside of the blade cannot be thoroughly cleaned and disinfected

Therefore, the above-mentioned ultrasonic scalpel can only be used as a one-time surgical instrument according to the regulations, and should be discarded after the operation is completed, but its price is high, and there is also a huge potential risk of medical ethics: In order to seek economic benefits, the used ultrasonic scalpel is privately disposed of. After incomplete cleaning and disinfection, it is inevitable to increase the risk of cross-infection before using it on the next patient

[0005] In view of this, Chinese patents CN201410023651.2, CN201810130712.3, CN201810871843.7, and CN201811114966.2 have designed some replaceable tool bar assemblies, but some of these assemblies have complex structures, high manufacturing costs, and inconvenient assembly. The base of the casing assembly on the outer periphery of the cutter bar is made of metal, so that the setting of the inner and outer casings needs to be realized by expanding tubes, turning grooves, etc., and the processing efficiency and cost remain high; some do not have the function of preventing reverse rotation , may cause slight displacement during ultrasonic vibration and affect the accuracy of surgery
