  • Patent number: 9597092
    Abstract: A piece of mechanized surgical equipment is provided, which includes an instrument holder having an element for receiving and retaining a surgical instrument for mechanized use. Also provided is a surgical instrument for mechanized use and configured to be mounted on the instrument holder. The element for receiving and retaining is mobile between an unlocking position, in which the element enables insertion of the instrument into the instrument holder or withdrawal thereof, and a locking position, in which the element prevents the withdrawal of the instrument from the instrument holder. Furthermore, the equipment includes a case in which an active blade of the instrument can be removably housed, the case having an engaging element for engaging with the receiving and retaining element so as to cause the element to move from the unlocking position to the locking position, or vice versa.

  • Publication number: 20110129795
    Abstract: The invention relates to a device for axial retention of a dental instrument shank and for transmitting the rotational driving of the instrument. The device is arranged in a head of a contra-angle or handpiece. The shank has an annular groove in which at least one stud is able to engage radially, and a flat permitting rotational driving of the shank. The rotational movement is communicated by an output pinion of a mechanical transmission assembly coupled to a drive motor and arranged in a sleeve joined to the head of the contra-angle. The device is formed by a shaft traversed axially by the instrument shank, at least one elastic lever, and at least one pin. There is cooperation of the pin or pins with the flat provided on the instrument shank.

  • Publication number: 20100099057
    Abstract: The invention relates to a method for designing and producing a package intended for the protection and/or transportation of a product. All of the digital design steps for the package are integrated in the method for digitizing the product, which includes a step of laminating a virtual key form of the product used to define geometrical data of each layer of the package to be cut. Then, the cutting is carried out followed by the stacking of the layers of the package defined by the design steps for said package to form a real package. The invention also relates to the package obtained by the method.

  • Publication number: 20090142730
    Abstract: The invention relates to a device for holding a dental instrument in the head of a contra-angle, an instrument of the type comprising, in its upper part which is inserted into the head of the contra-angle, a lateral flat for rotating it and an annular groove for axially retaining it, characterized in that the shank receiving the handle of the instrument, comprises a transverse cutback (7d), offset with respect to the longitudinal axis (7e) of the shank, made in the end of the shank and emerging in the bore (7b), the width (1) of the cutback being such that it allows the handle of the instrument to be engaged so that, on the one hand, the lateral flat of the handle is in contact with the wall (7f) of the cutback, closest to the longitudinal axis (7c), so as to ensure rotational coupling, and that, on the other hand, the shoulder of the flat of the handle abuts against the bottom (7c) of the longitudinal bore (7b) of the shank, in order to act as an axial stop in the direction of insertion.

  • Publication number: 20090118737
    Abstract: The invention relates to a contra-angle for implantology or surgery with a head for holding and rotating an instrument about its longitudinal axis, and a handpiece containing, in a non-limiting manner, a connection providing the connection with an external motor drive, and a reducing assembly with an output gear. The contra-angle is formed of removable subassemblies, and principally of a subassembly called the intermediate support, including an input gear meshing with the output gear of the reducing assembly and an end gear mounted on the same rotating shaft and inside a hollow cylindrical body. The intermediate support is mounted so as to slide freely along an axis inside a central part of a head body and enabling positioning in the head and rotational driving of a removable head cartridge, when all the subassemblies are mounted together to form the contra-angle.

  • Publication number: 20080182226
    Abstract: The invention relates to a device for attaching instruments. The device includes a rotary shaft intended to accept the instrument and rotationally drive it. The device also has at least one peg that can be retracted elastically until it can fit into the latching groove, thus axially retaining the instrument. A catch rotates as one with the rotary shaft and, in combination with the rotary shaft, gives the shape combined with that of the driving flat of the shank of the instrument. There is the particular feature of retracting radially or longitudinally if the flat is correctly orientated and resuming the position in which it rotationally drives the instrument. The flat of the instrument generally adopts the appropriate position when turned as soon as the slightest rotational force is applied to it. The instrument is released by action on a push-button, which moves the peg aside or radially retracts it.
