Embodiment Construction
[0011] Various preferred embodiments of the invention are discussed below. However, those skilled in the art should understand that the detailed description herein is not intended to limit the protection scope of the present invention, and the present invention can also be realized through the modification of the following embodiments or other equivalent methods.
[0012] The stent processing technology includes laser dry cutting and wet cutting. In one embodiment of the present invention, dust, water mist and metal vapor produced during the process are absorbed by a dust collection device, and recycled into the dust collection box of the dust collection device. During the laser wet cutting process, the water guide mechanism guides the pure water to the cutting point to assist in the processing, and the sewage generated during the processing is collected into the water collection pipe. As an example, the separation and recovery device proposed by the present invention may inc...

The invention discloses a device for recovering residues produced by medical support laser processing. The device comprises 1, a dust retention tank which is used for collecting and cooling flue dust, water mist and metallic vapor produced by cooling processing, 2, a water collection pipe which is used for receiving the cooled water flow from the dust retention tank and collecting other sewage produced by processing, 3, a setting tank which is used for receiving the sewage from the water collection pipe and carrying out primary filtration, 4, a first scroll separator which is used for receiving the primary filtration purified liquid from the setting tank and carrying out secondary filtration, 5, a residue collection device which is used for collecting solid residues from the dust retention tank, the setting tank and the first scroll separator and flushing the solid residues by purified water, 6, a magnetic separator which is used for carrying out magnetic separation of the flushing liquid containing the solid residues to obtain magnetic solid particles, 7, a second scroll separator which is used for receiving the separated flushing liquid and carrying out filtration to obtain non-magnetic solid particles, and 8, a drying tank which is used for respectively drying the recovered magnetic solid particles and the non-magnetic solid particles.
Description
technical field [0001] The invention relates to the technical field of laser micromachining, in particular to a device for separating and recycling waste generated during laser processing of medical brackets. Background technique [0002] A stent is a metal mesh structure implanted in vascular lesions to dredge blocked or stenotic areas, improve blood flow in lesions, and support blood vessels. At present, laser processing is the main processing method of medical stents, which is to move the overlapping laser pulse points along the cutting line on the pipe, and at the same time input high pressure oxygen to assist melting and cutting. The material at the laser focus point is melted and gasified, and the slag is blown out by the gas, forming a cutting track on the metal pipe wall. [0003] At present, most of the stent pipes rely on foreign imports, which are extremely expensive. During laser processing, the molten metal particles carried away by the high-pressure auxiliary...
