Abstract
The utility model discloses a spiral-flow type smoke absorbing knife head cover for a laser therapy device. The tangent direction of the column-shaped side surface of a big knife head [1] along the inner surface of the column shape is provided with an air pumping pipe [2]; an isolating cover [4] whose diameter is less than the inner diameter of the column shape is arranged at the center of the big knife head; the side of a taper absorbing mouth at the front end of a knife head cover is provided with an aided absorbing mouth [6] which can carry out tangency with the taper inner surface. The utility model has good smoke and smell removing action. The utility model can not influence the visual field and can not pollute the lens. The utility model can extend the service life so as to ensure the operation effect.
Description
This utility model belongs to the auxiliary device of medical apparatus and instruments.
During laser surgery, because acting on tissue, laser scalpel can produce smog and the band abnormal flavour that is harmful to human body, when intracavity operation, smog also can influence the operation visual field, once obtains the ZL95235163.0 patent for getting rid of smog, has solved the problems referred to above, but the influence that quickened by the air-flow straight line because of the dust in the smog in use, can pollute lens, influence light transmittance, reduce the delivery efficiency of laser.
This utility model is the improvement of ZL95235173.0 patent, and purpose provides a kind of more efficiently spiral-flow type smoking tool bit casing that does not pollute lens.
A kind of spiral-flow type smoking tool bit casing of laser therapy aparatus with arm, it is characterized in that along the tangential direction of cylindrical inner face an exhaust tube [2] being arranged in the cylindrical sides of tool bit casing [1], the separation sleeve [4] of a diameter less than cylindrical inner diameter put at the center, in the conical suction inlet side of tool bit casing front end the auxiliary suction inlet [6] tangent with conical inner face arranged.
When using, this utility model bleeding point is connected with the filtration smoke consuming apparatus with conduit, the smog that operation produces, because the tangential direction air-flow that negative pressure in the tool bit casing and suction inlet and auxiliary suction inlet enter produces spiral-flow type air-flow space vapour discharge through separation sleeve and tool bit casing inwall in tool bit casing.
The utility model has the advantages that smoke abatement goes flavor to make good use of, do not influence the visual field, do not pollute lens, increase the service life, guaranteed surgical effect.
Accompanying drawing is the structural representation of laser therapy aparatus with spiral-flow type smoking tool bit casing, and wherein Fig. 1 is a front view, and Fig. 2 is a vertical view.
Lens 6--on the 1--tool bit casing 2--exhaust tube 3--suction inlet 4--separation sleeve 5--therapy apparatus assists suction inlet
When this utility model is implemented, with metal garden material through car, mill, bore be processed into inside and outside for the rear portion be that cylindrical, front portion is the tool bit casing that conical threaded mouth and front end have mouth, all side mouths all are oriented in a tangential direction with inwall, and process step in the rear end, certainly technology advanced person's also available forging type processing, in addition with the separation sleeve of material processing diameter in same material garden less than cylindrical inner diameter band edge, the separation sleeve edge is placed in the step, reuse thin garden of the same race material is processed threaded exhaust tube, twists on the screw thread mouth of tool bit casing to get final product.
