An intelligent surgical laser knife

Abstract

The invention relates to an intelligent surgery laser knife comprising a laser emitter, a laser controller, a self-focusing lens, an optical fiber connector, an optical fiber, a coupler and a scalpel body. Laser beams output by the laser emitter are converged at a point via the self-focusing lens, and then enter the optical fiber via the optical fiber connector, then are coupled by the coupler via the optical fiber; then laser energy is transmitted to a laser knife pen; the laser controller comprises a microprocessing chip, a high-temperature temperature sensor, an analog-digital conversion circuit, a laser pulse width modulation circuit and a laser pulse peak value modulation circuit; the microprocessing chip comprises a temperature determining unit, a pulse width calculation unit, a pulse peak calculation unit, a pulse width control unit and a pulse peak control unit. The intelligent surgery laser knife has great reliability; and laser can be automatically adjusted via the laser knife, so high temperature stability produced by the laser knife can be effectively maintained.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a laser knife, in particular to an intelligent surgical laser knife. Background technique [0002] Traditional surgical cutting equipment cuts tissue by releasing high-frequency current, and there are unsafe factors when the current flows through the patient's body, and high-frequency equipment cannot be applied to patients with metal implants in the body. There are unsafe risks affecting other surgical instruments. The laser scalpel achieves cutting and disinfection through high-temperature cutting. No current flows through the patient and will not affect other patients with metal implants in the body. Because the laser does not emit radio frequency, it will not interfere with other surgical instruments, so , the advent of the laser scalpel will absolutely replace the high-frequency electrosurgical equipment. [0003] Laser is monochromatic light with certain penetrating power a...
