2results about How to "Guaranteed drilling effect" patented technology

The utility model discloses a surgical electric drill collimating device, including base, the top of base is installed electric sliding table, the movable end fixed mounting of electric sliding table has the support frame, the top of support frame is installed electric telescopic handle, the movable end fixed connection of electric telescopic handle has the ball seat, the outer surface one side of ball seat is rotatively inlaid with the sphere, the outer surface one side fixed connection of sphere has the long pole, the outer surface rotatively connected with four mounting seats of ball seat, two sides inner wall of four mounting seats all are rotatively connected with first electric push rod, and the movable end all with long pole between first electric push rod rotatively connected. In the utility model, through cross -positioning and visual camera cooperation can realize collimating positioning, and through mechanical structure cooperation can realize automatic drilling, replace original manual drilling operation, reduce the requirement to the doctor skill, can prevent the phenomenon such as slippage, deviation, guarantee drilling effect.

This utility model relates to the field of rechargeable drills with protective structures, and discloses a rechargeable drill with a protective structure, including a charging box, a drill body disposed on the upper side of the charging box, and a drill bit fixedly connected to one side of the drill body. A support and positioning mechanism is disposed on the outer side of the drill bit, and a protective mechanism is disposed on the upper side of the drill body. The support and positioning mechanism includes a slide cylinder, which is fixedly connected to one side of the drill body. A sliding plate is slidably connected inside the slide cylinder. A support rod is fixedly connected to the side of the sliding plate away from the drill body. The support rod is slidably connected inside the slide cylinder. A spring is fixedly connected between the side of the sliding plate away from the support rod and the inner wall of the slide cylinder. The protective mechanism is used to absorb and separate the debris that may be generated when the drill bit is working, achieving the effects of protection, debris separation, and long-lasting use. The support and positioning mechanism is used to provide planar positioning and scale coordinates for users when drilling, increasing practicality.
