Cold head for medical laser equipment

Abstract

The invention relates to a cold finger for a medical laser device, which comprises a working part, a main body part, a cold air supply device, a semiconductor refrigeration piece and a cold air sleeve. An annular air cavity is arranged in the main body part. The main body part is far away from the working part end face and is provided with a main body air inlet and outlet which are communicated with the air cavity. The cold air supply device is provided with a temperature adjusting button. One end of the main air inlet pipe is connected with the air inlet of the main body, and the other end ofthe main air inlet pipe is connected with the cold air supply device. One end of the main air outlet pipe is connected with the air outlet of the main body and the other end is communicated with theoutside. The semi-conductor refrigeration piece is arranged on the outer surface of the main body part. The cold air sleeve is sleeved outside the semiconductor refrigeration piece, and a cold air inlet and outlet are arranged on the cold air sleeve. One end of the air inlet pipe branch is connected with the cold air inlet, and the other end of the air inlet pipe branch is connected with the mainair inlet pipe. One end of the air outlet pipe branch is connected with the air outlet of the cold air, and the other end of the air outlet pipe branch is connected with the main air outlet pipe. Thetemperature of the cold head for the medical laser device of the present invention is adjustable.

Description

technical field [0001] The invention relates to a cold head for medical laser equipment. Background technique [0002] Existing medical lasers include a host and an operating end, and the operating end includes a housing, a cold head disposed at the front end of the housing, a laser cavity disposed adjacent to the rear of the cold head, a laser diode disposed in the laser cavity, and a laser diode disposed on the cold head. Cooling device, laser cavity, laser diode and cooling device are in the housing. [0003] The front end of the cold head protrudes from the shell and directly contacts the skin, and the cooling device can reduce the temperature of the cold head to the freezing point, so that the human body will not feel the pain caused by the laser heating. [0004] The existing cooling device includes a cooling plate and a cooling water circulation system, and the cooling temperature is not adjustable and cannot be adjusted according to the needs of patients.
