A blunt dissector for endoscopic vein harvesting has a generally-cylindrical sheath for retaining an elongated endoscope. The sheath is elongated between a distal end and a proximal end. A transparent tip is disposed at the distal end of the sheath.A handle is disposed at the proximal end of the sheath. The sheath includes a selectably closable longitudinal slot having an opened configuration such that the endoscope can be inserted radially into the sheath. The longitudinal slot has a closed configuration that retains the endoscope within the sheath and presents a substantially it) smooth outer surface for use during dissection.

A laser annealing apparatus comprises a laser oscillator having a Q switching action, one or a plurality of partially reflective mirrors for split a laser beam emitted from the laser oscillator into a plurality of laser beams, a plurality of optical fibers which respectively transmit the plurality of laser beams split by the partially reflective mirrors, and whose respective emission ends are arranged linearly in one direction, a first optical system for synthesizing and homogenizing the plurality of laser beams emitted from the optical fibers, and a second optical system for focusing the laser beam emitted from the first optical system on the work piece surface as a rectangular laser beam whose beam shape is long in the lateral direction and short in the longitudinal direction. As a result, laser power transmission by means of slender optical fibers is possible even in cases in which a green laser such as the second harmonic of an Nd:YAG laser having a Q switching action or the like is used as a heating light source. Accordingly, a compact laser annealing apparatus that has a high-quality working performance and does not require a laser amplifier or high-frequency generating apparatus can be obtained.

The invention discloses an air purifier. The air purifier comprises a shell with an air inlet and an air outlet; the air purifier further comprises a flowerpot assembly, a microorganism box, an ecological purifying system of a water tank, a filtering system and a control system used for controlling, wherein the flowerpot assembly, the microorganism box, the water tank ecological purifying system, the filtering system and the control system are arranged in sequence; water of the ecological purifying system flows through the filtering system so as to bring dust and VOCs which are absorbed by the filtering system into the ecological purifying system for purification; the flowerpot assembly comprises a flowerpot, water of the water tank enters the flowerpot through a water inlet, and when the water level is higher than a water outlet, the water flows through the microorganism box to enter the water tank so as to form water circulation. The air purifier is simple in structure, easy and convenient to operate and low in cost; the purification efficiency on air pollutant, in particular to the VOCs, is high, the dust and the VOCs are blocked when air flows through the filtering system and are brought into the microorganism box under the effect of the water flow, the VOCs are decomposed and purified through microorganisms, and the dust is brought into the flowerpot assembly under the effect of the water circulation so as to be absorbed and used by roots of plants; the ecological purification technology is used, so that environmental protection is achieved.
