Description

A semiconductor lighting surgical instrument

technical field

The invention relates to a surgical instrument, in particular to a semiconductor lighting surgical instrument.

Background technique

At present, there are blind spots in plastic surgery, such as liposuction, breast augmentation, lower forehead and other skin incision superficial operations. To overcome the phenomenon of "partial blind operation" in outpatient operations, one person needs to hold a lighting device during the operation, and the other person Carry out plastic operation with surgical instrument, bring a lot of inconvenience to operation.

Contents of the invention

The object of the present invention is to provide a semiconductor lighting surgical instrument in order to overcome the phenomenon of "partial blind operation" in outpatient surgery.

The technical solution of the present invention is a surgical instrument for semiconductor lighting, which includes an operating terminal, an instrument body, and a handle. There are built-in wires, and a lithium battery is built in the handle. The interface at the operation terminal, the semiconductor cold light source chip, the wires connected to the lithium battery, and the pressing electrodes constitute a disposable semiconductor lighting cold light source.

The semiconductor cold light source chip adopts a high-power semiconductor blue light LED chip or LD chip, and the connection interface between the cold light source and the operation terminal adopts excessive fit, and is soft-sealed with silicone rubber to form a non-leakage interface.

The invention adopts cold light semiconductor lighting technology, integrates with conventional surgical instruments through a special anti-seepage interface, and provides sufficient lighting and indication needs for surgery without affecting the original use and inherent characteristic characteristics of the instrument. Since the cold light source is connected with the original surgical instrument and the added lithium battery through the interface, the plug-in electrode, it is easy to assemble and disassemble, and can be sealed and aseptically packaged for one-time use. The interface of the instrument body part is located in the handle part, that is, the non-contact part. In order to prevent the contamination of bacteria-carrying drops and bacteria diffusion during the operation, this development process considers plasma sterilization at room temperature for non-one-time use metal instruments and interfaces to achieve Requirements not to destroy the original material properties of the device and interface. The instrument equipped with a disposable lighting source forms an irradiation area of 4-5 square centimeters at the operating terminal. Since the light source used is a cold light source, it has no thermal effect on the cut biological tissue and has good color rendering. During the operation, the coordinate position of the surgical instrument and the position of the blood vessel that changes color under the cold light can be determined by two methods of incision and skin penetration, so as to achieve the limited displacement of the instrument and the function of avoiding blood vessels. Without the use of endoscope, it can Fully guarantee the safety and effectiveness of the operation.
