Contact type laser surgical knife

Abstract

The invention discloses a contact type laser surgical knife. The contact type laser surgical knife comprises a knife handle, a knife rod and an optical fiber assembly, wherein a mounting slot is formed in one end of the knife handle, a second servo motor is mounted in the mounting slot, a gear sleeve is fixed at the terminal of an output shaft of the second servo motor, a third gear is inserted into the gear sleeve, and a U-shaped mounting seat is fixed on the edge of the third gear; a first servo motor is mounted in the mounting seat and is of a double-shaft motor structure, and first gears fixedly sleeve two output shafts of the first servo motor; rotating shafts are rotatably inserted into inner walls on two sides of the mounting seat, second gears fixedly sleeve the rotating shafts; and a boss is fixed at one end of the knife rod. According to the contact type laser surgical knife, a laser knife head can be advantageously adjusted to a proper position, so that operation is very convenient, and the operational convenience of the surgical knife is greatly improved.

Description

technical field [0001] The invention relates to the technical field of laser scalpels, in particular to a contact laser surgical scalpel. Background technique [0002] Laser scalpel, using the characteristics of highly concentrated laser energy, uses it as a surgical "knife" in surgery, which has its unique features. The commonly used carbon dioxide laser "knife", the blade is the focal point where the laser beam gathers, the focal point can be as small as 0.1 mm, and the power density at the focal point can reach 100,000 watts per square centimeter. Wherever such a light "knife" goes, whether it is skin, muscle, or bone, it will be solved easily. One of the outstanding advantages of the laser "knife" is that it is very light. There is no mechanical impact when using it for surgery; after using a laser "knife" with a power of 50 watts, the speed of skin incision is about 10 cm per second, and the incision depth is about 1 mm, which is similar to that of ordinary scalpels. ...

AI Technical Summary

Problems solved by technology

[0003] The existing laser scalpel has a straight-rod structure, and the blade head cannot be bent during use. However, we know that in actual operations, some corners are often encountered that cannot be directly touched, which leads to the ineffective operation. It brings great trouble and also limits the application of laser scalpel. To solve such problems, we propose a contact laser surgical scalpel
