Wash convenient smokeless laser tool bit

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a smokeless laser knife head convenient and fast to clean.

Background

The laser scalpel is used as a scalpel for surgical operation by utilizing the characteristic of high concentration of laser energy, can greatly reduce the labor intensity of doctors in the specific operation process and relieve the pain of patients, and is more and more widely used. However, when laser is used to vaporize human tissues, a lot of harmful smoke and peculiar smell can be generated at the same time, which is beneficial to the propagation of bacteria, harmful to human bodies after human bodies are inhaled and influences the working visual field of operators. At present, the hospital generally adopts a range hood, a dust collector or a fan to solve the harmful smoke and peculiar smell, but the range hood, the dust collector or the fan has certain limitation, or the effect is not good, and the cost is too high. Therefore, it is necessary to design a laser tool bit capable of smoking, which can reduce the diffusion of smoke and peculiar smell;

in order to overcome the technical problems, Chinese patent (patent publication No. CN208355555U) discloses a laser smoking tool bit, which comprises a tool bit seat, an inner tube, an outer tube, a connecting tube and an air duct, wherein the inner ring of the tool bit seat is provided with a first joint, the inner tube is connected with the first joint, the outer ring of the tool bit seat is provided with a second joint, the outer tube is connected with the second joint, a first cavity is formed inside the inner tube, a second cavity is formed between the outer wall of the inner tube and the inner wall of the outer tube, and the first cavity and the second cavity are of mutually independent structures;

although the technical scheme adopts the way that the smoke suction channel, the smoke exhaust channel and the second cavity are communicated with each other, and one end of the connecting pipe is connected with the negative pressure air source, smoke and peculiar smell generated during laser cutting are exhausted through the smoke exhaust channel; however, after the laser cutter head is used for a period of time, the second cavity is contacted with harmful smoke and peculiar smell for a long time, some substances in the smoke can be adhered to the outer surface of the second cavity, the efficiency of discharging the smoke can be reduced over time, and therefore the laser cutter head has to be cleaned frequently.
