Multifunctional laser surgical instrument

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multifunctional laser surgical instrument.

Background

The cutting hemostatic instruments commonly used in the current operation comprise an ultrasonic knife, a bipolar hemostatic forceps, a monopolar electric coagulation hook and the like, and along with the continuous updating of the development of laser surgical instruments and the continuous improvement of the quality of optical fibers, a laser surgical system has the development trends of small volume, high power, low price and the like, and provides a good energy source for surgical tools.

During surgical procedures, it is common practice to perform hemostasis by cutting with the aid of surgical instruments. In the age of minimally invasive surgery, how to perform a perfect operation is of great importance. The surgical instruments used in clinical practice at present include traditional cold knife, electric knife (monopolar and bipolar), electric coagulation hook, electric coagulation hemostatic forceps and ultrasonic knife, but have advantages and disadvantages in the operation process.

The cold knife can accurately cut tissues but can not effectively stop bleeding; although the electric coagulation and excision equipment is low in price, the thermal damage range is large, much smoke is generated, the cutting efficiency is not high (or the cutting cannot be performed), and the hemostatic capacity is limited during operation; with the development of ultrasonic instruments, ultrasonic knives are widely applied to operations, however, smoke generated by acting tissues in the operation process caused by the working principle of the ultrasonic knives is difficult to remove in time, particularly, the lenses need to be wiped in time in laparoscopic operations, the operation efficiency is affected, and the ultrasonic knives are more expensive than common electrosurgical instruments.

With the continuous development of laser medicine and the continuous research and development of lasers, laser surgical instruments gradually show the advantages of small size, high power, stable energy, low price and the like, and surgical instruments related to lasers are continuously developed and mature to apply. There are still many areas that have not been addressed and there is a need to develop applications to better facilitate the development of minimally invasive surgery.

The present invention is directed to the application of laser-like ultrasonic knives in surgical procedures in general. The related report of the assumption is not found at present through retrieval. The invention designs a multifunctional laser surgical instrument.
