The utility model relates to the technical field of tip testers, and provides an inspection module and an inspection system of a sharp tip tester, the inspection module comprises a base, the base is at least fixedly connected with a first inspection column, a second inspection column and a third inspection column, the first inspection column, the second inspection column and the third inspection column are vertically connected to the base, and the heights of the first inspection column, the second inspection column and the third inspection column are gradually increased; the first inspection column and the second inspection column are configured such that when the sharp tip tester is in a standard state, the first inspection column is not turned on, the second inspection column is turned on, and the height difference between the first inspection column and the second inspection column is 0.02 mm-0. 50 mm. The method has the advantages that whether the lighting depth of the tester has a large error or not is directly detected through the lighting condition, the method is efficient and convenient, the reliability of the detection result of the toy sharp point can be ensured during production, meanwhile, the scheme also provides an adjustment reference for calibration work, and the efficiency of the calibration work is improved.

A vitrector for removing material from an eye includes a hand piece, a shaft coupled at a first end to a first end of the hand piece, the shaft having a sharp second end opposite the first end of the shaft, and a cutting device positioned within the shaft and configured for removing the material from the eye. The sharp second end of the shaft is configured for piercing a pars plana of the eye and a sclera of the eye. A method for removing material from an eye includes forming a single opening through a pars plana of the eye and a sclera of the eye using a sharp point of a shaft of a vitrector, cutting the material using a cutting device incorporated within the shaft, and removing the material from the eye using the vitrector.

A pain relief hand tool device is disclosed, which is a series of hand tools for promoting healing. The pain relief hand tool device comprises an elongated handle component with a head component. The handle component is available in three different designs that can be applied to different areas of the body with ease. The head component is typically either round or rectangular-shaped. The head component also comprises nails or sharp points arranged to apply pressure to the skin but not puncture it. Users can choose a desired tool design and apply it to the body. The pressure applied can help relieve aches and pains, reduce stress, reduce inflammation, promote better cell health, improve circulation, etc.

This utility model relates to the field of skeleton assembly, and more particularly to a skeleton shell shaping mechanism. The clamping mechanism includes multiple shaping blocks that converge toward the center point. These shaping blocks, through convergence, form a shaping platform that applies uniform pressure to the outside of the positioning teeth. The inner top mechanism includes an inner top block and a lower pressure plate surrounding the inner top block. The inner top block passes through the shell on the lower pressure plate and compresses the positioning teeth that intersect with the movement path of the inner top block. It also forms a positioning mechanism that fixes the shell during shaping by constraining the positioning teeth with the shaping platform. First, the positioning teeth of the annular structure of the shell are shaped internally and externally. Through the cooperation of the clamping mechanism and the inner top mechanism, a structural repair effect is achieved. Second, since the positioning teeth have sharp points, the clamping mechanism is chosen to avoid contact with the sharp points and apply pressure from the side of the sharp points, thus avoiding the problem of secondary bending of the sharp points.

A hook assembly (18) is provided for use with an entanglement projectile (12). The hook assembly includes at least one hook (19) comprising an apex portion (22) and a sharp point (20) extending distally from the apex portion. A protective cover (26) is positioned adjacent to the apex portion of the at least one hook. The protective cover includes at least one substantially flat surface (28). The protective cover is positioned relative to the at least one hook such that the sharp point of the at least one hook extends distally from the protective cover and is therefore exposed while the protective cover is worn adjacent to the apex portion of the at least one hook.
