Abstract

The invention discloses a welding device for a minimally-invasive scalpel. The welding device comprises a laser, a concave reflection mirror and a working platform, wherein the laser comprises a working substance area, a total-reflection mirror and a semi-reflection mirror which are positioned in a shell, and the working substance area is positioned between a first total-reflection mirror and the semi-reflection mirror; the concave reflection mirror is used for changing a transmission direction of a laser beam from the laser and forming light spots; and the working platform is used for bearing a to-be-processed minimally-invasive scalpel and is formed by a bottom board, two side boards and a hanging board, bottom ends of the two side boards are respectively and fixedly arranged at the left side and the right side of the bottom board, the hanging board is fixedly arranged between the two side boards, and the inner side surface of the hanging board is fixedly provided with at least one support base which is used for containing a knife bar of the minimally-invasive scalpel and a fixing base which is used for fixing a knife handle of the minimally-invasive scalpel. The welding device disclosed by the invention is beneficial for accurately fixing the minimally-invasive scalpel, and thus the accuracy and the safety for welding are increased; and pulse heating duration time is extremely short, the size of welding spots can be smaller in dozens even hundreds of micrometers, and the welding accuracy is further increased.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a welding device for a minimally invasive scalpel. Background technique [0002] Minimally invasive surgery has a high degree of accuracy, does not cut off muscle fiber tissue, cuts out the diseased tissue in the body with less trauma, less bleeding, no large-scale wounds and no contact between intracavitary tissues and air, reducing the chance of infection, so the trauma is small and the pain is light , Quick recovery and welcome by patients. However, due to the narrow head of the minimally invasive scalpel, the precision requirements are extremely strict. Therefore, how to weld the handle and blade of the minimally invasive scalpel has become the direction of efforts of those of ordinary skill in the art. Contents of the invention [0003] The invention provides a welding device for a minimally invasive scalpel, which is beneficial to accurately fix the minimally invasive...
