Split type portable ultrasonic scalpel

Abstract

A split type portable ultrasonic scalpel comprises a power source assembly, a winder connected with the power source assembly, a grip transducer assembly connected with the other end of the winder and a detachable scalpel head assembly arranged on the front portion of the grip transducer assembly. Electric energy is output through the power supply assembly, is output to an ultrasonic transducer in the grip transducer assembly through the winder, is converted into high-frequency mechanical vibration through the ultrasonic transducer, is output to the tool bit working part through the conduction shaft rod to generate high-frequency ultrasonic vibration, and is used for adjusting the frequency of an output signal according to a clamped tissue and output feedback so as to achieve the optimal efficiency; the split type design is adopted, so that the arm burden of an operator is relieved; compared with a traditional ultrasonic scalpel, the ultrasonic scalpel has the advantages that the overall size and weight of the system are greatly reduced, and meanwhile, the weight of a handheld part is not increased; the system disclosed by the invention is reasonable in mass distribution and relatively high in use portability, comfort and controllability.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a split-type portable ultrasonic scalpel among surgical instruments. Background technique [0002] Ultrasonic cutting and hemostasis system (hereinafter referred to as "ultrasonic scalpel") is one of the widely used surgical instruments in the clinical medical process, and it is a precise and efficient energy surgical instrument. The ultrasonic scalpel integrates the three functions of tissue separation, cutting and hemostasis, which significantly improves the efficiency and safety of surgical operations. [0003] The ultrasonic scalpel is powered by an AC power supply, and a high-frequency electrical pulse signal is generated by a function generator and a signal amplifier, which is converted into a high-frequency mechanical vibration by the piezoelectric material of the ultrasonic transducer, and then transmitted to the The working part of the cutter head finally ou...

AI Technical Summary

Problems solved by technology

However, because the wireless ultrasonic scalpel has strict volume restrictions on each component while pursuing practical convenience, it still has many technical deficiencies and defects.

First of all, due to the size limitation of the power supply components, there are serious shortages in output power, cutting efficiency and continuous workability

When the operation time is long, the battery needs to be replaced frequently, which increases the risk of extra operation and infection during the operation

Secondly, most of the components are concentrated on the hand-held handle of the ultrasonic scalpel, resulting in an unreasonable overall weight distribution. Unexpected movement and tremors will occur at the head of the working knife during operation, which seriously affects the precise operation of the operation and greatly increases the Reduced the risk of secondary injury to important nerves and blood vessels during the operation

In addition, the heavy hand-held operating parts increase the physical burden of the operator, and are prone to fatigue during long-term operation, which affects the refinement and precision of the operation.

Finally, the cost of existing wireless ultrasonic scalpels is relatively high, and wide-scale use will significantly increase hospital operating costs, and thus increase the medical economic burden of patients
