Manual-automatic integrated light spot adjusting device for operating shadowless lamp

Abstract

The invention discloses a manual-automatic integrated light spot adjusting device for an operating shadowless lamp. The manual-automatic integrated light spot adjusting device comprises a shell, a plurality of lifting guide rails are fixed in the shell, a lifting sleeve is arranged on the lifting guide rails in a matched mode, a motor base is fixed to the top ends of the lifting guide rails, a motor is fixed on the motor base, a screw is arranged in the lifting sleeve in a penetrating mode and is connected to the lifting sleeve in a threaded mode, one end of the screw is connected to an outputshaft of the motor through a first electromagnetic clutch, the other end of the screw is connected to a focusing handle through a second electromagnetic clutch, and the focusing handle is arranged atthe bottom of the shell in a penetrating mode. According to the manual-automatic integrated light spot adjusting device, one end of the screw is connected to the motor through one electromagnetic clutch, the other end of the screw is connected to the handle for adjusting light spots through the other electromagnetic clutch, when the motor is started or the handle is manually rotated, the screw rotates to drive the lifting sleeve to move up and down so as to drive an LED lamp panel to rotate, and therefore the purpose of adjusting the light spots is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a manual and integrated light spot adjustment device for a surgical shadowless lamp. Background technique [0002] The surgical shadowless lamp is a medical device used to illuminate the surgical site, and is used to observe small, low-contrast objects at different depths in the incision and body cavity during surgery. Since the operator's head, hands and instruments may cause interference shadows on the surgical site, the surgical shadowless lamp can eliminate shadows as much as possible and minimize color distortion, ensuring that the operator can clearly see the surgical cavity. Organs, tissues and blood vessels, as well as to see clearly the deep part of the inner cavity, so the shadowless lamp is a necessary equipment in the hospital operating room, and plays an important role in lighting during the doctor's operation. The adjustment mechanism of the existing shad...
