Portable high-frequency electric knife controller

Abstract

The invention discloses a portable high frequency electric knife controller which comprises a central control module, a driver module, a power output module, a signal acquisition module and a power supply nodule. For the central control module, (A) is used to provide a PWM driving signal for the driver module; (B) is used to detect a system power supply signal feed backed by the power supply nodule; (C) is used to control the working model of an inverted rectifying circuit in the power supply nodule; (D) is used to scan and detect an electric knife handle and a patient counter electrode; (E) is used to provide a man machine interface connected with an external parts; the combined application of the controller and the high frequency accessory of the invention is wider than the application scope of the common high frequency electric knife. The invention is particularly suitable for the first aid of field wounded personnel, the first aid of war wounded personnel and the first aid of traffic accident wounded personnel, suitable for the first aid of field engineer wound personnel, suitable for the first aid of offshore wounded personnel, suitable for all occasions without a power supply condition, suitable for the cutting and the arrest bleeding of open wounded personnel, and suitable for the first aid of an accident event, such as the first aids of earthquake wounded personnel, water flood wounded personnel, typhoon wounded personnel, war wounded personnel and traffic accident wounded personnel.

Description

technical field [0001] The invention relates to a controller of a high-frequency electric knife, more particularly, refers to a portable high-frequency electric knife controller using an Atmega16 single-chip microcomputer as a control platform. Background technique [0002] High-frequency electric knife (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. [0003] At present, the high-frequency electric knife is composed of accessories such as a controller (commonly known as the host), an electric knife handle, a patient plate, bipolar tweezers, and a foot switch. Generally, the main engine includes a casing, and control circuits and electronic components instal...

Problems solved by technology

[0005] However, in places where some emergencies occur, due to the disadvantages of large size and heavy weight, the existing high-frequency electric knife is not suitable for portability, and is not conducive to providing blood coagulation treatment for the wounded, causing the wounded to lose blood due to excessive blood loss. chance of rescue
