Description
Technical Field
The utility model relates to a mechanical insulation performance detection device especially relates to an electrosurgery instrument insulating properties detection device.
Background
Reference is made to WS 310.1-2016, the hospital disinfection supply center health industry standard, issued in 2016, where two sections mention surgical tape power supply instrument insulation performance testing. According to WS 310.1-2016, Hospital Disinfection supply center part 1: the management standard stipulates that the device inspection tire, the cleaning article, the device cabinet, the dressing cabinet, the packaging material cutting machine, the medical heat sealing machine, the cleaning article loading equipment, the magnifier with a light source, the pressure air gun, the insulation detector and the like are required to be arranged. According to WS 310.1-2016, Hospital Disinfection supply center part 2: the technical operating specifications of cleaning, disinfection and sterilization stipulate that safety inspection such as insulation performance and the like should be carried out on instruments with power supplies.
In hospital surgery, an electrosurgical instrument has become an indispensable device in an operating room, performs cutting, coagulation and other operations by using a thermal effect generated by high-frequency high-voltage current on biological tissues, and is widely applied to dermatology, gynecology, cardiac surgery, orthopedics, ophthalmology, spinal department, otolaryngology, orthopedics, urology, neurosurgery and the like, general surgery and certain dental operations. Electrosurgical instruments are inherently dangerous due to the use of high frequency voltage current, and their insulation is the most important safety protection for patients and surgeons. When leaving the factory, the manufacturers of the electrosurgical instruments can use the insulating layers to wrap the conducting layers of the instruments, except for the working areas required by the operation, other parts such as handles and cables contacting the body cavities of patients and hands of operators are protected by the insulating layers, so that the non-operation parts of the patients and the operators are prevented from being burnt by high-frequency high-voltage current, and medical accidents are avoided.
According to the circuit backflow principle of the electrosurgical instrument, the electrosurgical instrument can be divided into a monopolar instrument and a bipolar instrument, wherein the working voltage of the monopolar instrument is (1350-9000) V; the working voltage of the bipolar instrument is (300-1200) V. The insulating layer can be said to be the only means by which these high-frequency voltages can be isolated. In actual operation, the insulating layer is used for preventing improper use, abrasion and tearing, failures caused by poor operation or damage of mechanical accidents, but at the same time, the possibility of thermal breakdown and electrochemical breakdown is gradually accumulated along with the increase of the using time and the using frequency of the instrument through long-term work, namely, the damage of the insulating layer can be accumulated along with the passage of time, and once the damage occurs, medical accidents are easily caused.
In clinic, the most common accidents of insulating layer damage are: electric shock injury, such as operation respiration and sudden cardiac arrest; electric burn; organ burns; electrically injuring medical personnel and even causing operating room fires. In the recommended practice of electrosurgical instruments, the american society of operating rooms and nurses mentions that the insulation layer is mainly damaged on the instruments and the connecting wires of the instruments, and that knotting and collision may occur during the use, recycling, cleaning, packaging, sterilization, etc., which may result in the damage of the insulation layer on the surface of the instruments and the insulation layer on the connecting wires.
The detection of the insulating property of the electrosurgical instrument before operation is very important. The traditional insulation performance detection method comprises the following steps: visual inspection combined with resistance gear detection of a multimeter is time-consuming and labor-consuming, and many hidden insulation layer damages can be omitted.
At present, the development of domestic related detection devices is relatively laggard, developed countries use an insulation detector to carry out insulation layer detection on powered surgical instruments, and the instruments after cleaning and drying are subjected to insulation performance measurement, and two detection modes are mainly used: monopolar and bipolar modes, using different detectors for different powered surgical instruments, such as: the long-strip-shaped instruments and instrument connecting cables are monitored by using a cable detector, and the detection parts of the long-strip-shaped instruments and the instrument connecting cables are wrapped by 360 degrees by using special structures and move back and forth; the insulating detection brush is used for detecting the irregularly-shaped surgical instrument with the power supply, so that the damage of the insulating layer can be effectively detected.
The repeated processes of wrapping and brushing need to be in close contact with each other or even extruded to ensure the integrity of detection, the whole detection process is a process of damaging the insulating layer, and the wrapping and brushing are currently suitable detection methods on the premise of no better detection device.
