Abstract: Disclosed are a contact-type laser operating head and a device for use in medical treatment and cosmetology with laser. The contact-type laser operating head mainly comprises a light emitting port fixture (8) and several light emitting modules forming a light emitting port. The light emitting modules on the periphery and the light emitting port fixture (8) as well as the adjacent light emitting modules are connected by connectors (7). The connector (7) itself or an adaptive connecting structure thereof enables the light emitting modules to be driven to rotate independently so as to follow and attach to the surface to be treated. The light emitting module comprises a lens fixing frame (5) and an optical fibre fixture (6), wherein the lens fixing frame (5) is used to mount a functional lens (2), and the optical fibre fixture (6) is fixedly mounted behind the lens fixing frame (5) for packaging a coupled optical fibre (4) and keeping a light beam output from the optical fibre (4) perpendicular to a lens surface.
