摘要: A surgical apparatus having a locking mechanism that receives a cutting burr and that may include a loading and running position. The locking mechanism may include a motor driven spindle that carries a locking pawl and a detent pawl that lock the cutting burr in place an prevent the cutting burr from inadvertently falling out of the surgical drill instrument when in its load position. A diamond-shaped portion of the cutting burr may be formed in a six-sided diamond configuration and a perpendicular back end surface. The end of the cutting burr may include another diamond-shaped portion formed in a six-sided diamond shape surface that mates with a complementary surface formed in the receiving end of the spindle of the motor/locking mechanism. In an aspect, the attachment of the cutting burr is such that the cutting burr has substantially zero axial movement and runs true in the running condition.

摘要: The present application discloses a quick-action coupling (100) for a rotary surgical tool having a rotary shaft (20), in the distal end surface of which there is formed a tool receptacle (24) which is adapted to receive a rotary surgical tool for conjoint rotation. The rotary shaft (20) has, in the region of its distal end (21), at least one radial protrusion (22) and at least one radial aperture, wherein a locking body is arranged in the at least one aperture, said locking body being movable in the radial direction with respect to the rotary shaft (20). A sleeve (10), the proximal end of which is pushable over the distal end (21) of the rotary shaft (20), is additionally provided in the quick-action coupling. The inner surface of the sleeve (10) contains a region in which the inside diameter of the distal section (102) is enlarged compared with the inside diameter of the proximal section (101), and the sleeve (10) has at least one slot (11, 11′, 12, 12′, 13, 13′, 13″, 14, 15, 16, 17) which has a first slot section (11, 11′) and at least one further slot section (12, 12′, 13, 13′, 13″, 14, 15, 16, 17), wherein the first slot section (11, 11′) extends from the proximal end of the sleeve (10) and the further slot section (12, 12′, 13, 13′, 13″, 14, 15, 16, 17) is connected to the first slot section (11, 11′). An elastic element (30) urges the sleeve (10) in the distal direction relative to the rotary shaft (20).

摘要: Devices are described relating to the retaining of surgical tools within the chuck of a reciprocating surgical instrument, such as a reciprocating saw. A securing chuck is disclosed for securing a surgical tool to a reciprocating surgical instrument that comprises a shaft and a securing member. The shaft defines an axis and has a cylindrical bore extending along the axis. The bore is shaped to receive a substantially rounded tool shank. A pair of transverse slots extends into the shaft along a plane passing through the axis for receiving a substantially flattened tool shank. The transverse slots intersect with the cylindrical bore. The securing member is carried by the shaft and is radially movable relative to the bore both inwardly and outwardly to secure the surgical tool in the chuck.

摘要: A cutting tool has a cutting insert and a holder. The cutting insert has a cutting portion and an insert shank with a cylindrical portion and a non-cylindrical portion. The holder has a clamping portion which has a clamping sleeve and a cage located therein. The cage includes a load member housing with a load member. The cage has a major abutment wall adjacent to a minor abutment wall. The clamping sleeve has first and second inner sections defined by points P1 and P2. A point P3 divides the second inner section into first and second portions. The clamping sleeve is rotatable between a secured and a released position of the cutting tool. In the secured position, the non-cylindrical portion abuts the major abutment wall, the cylindrical portion abuts both the minor abutment wall and the load member, and the load member abuts the first portion.

摘要: The invention relates to a clamping device (8) for connecting a saw blade (12) to a reciprocating rod (6) of a jig saw, in particular a hand-operated compass saw (2), comprising a mounting (20), which is connected to the reciprocating rod (6) and has a recess (22) for receiving a head end (10) of the saw blade (12), a locking sleeve (30), which can be turned about the axis (40) with respect to the mounting (20) against the force of a torsion spring (60) to lock the head end (10) of the saw blade (12) in a locking position in the recess (22) and to allow removal of the saw blade (12) in a removal position. It is intended that a stop (78) interacts with a part (80) of the torsion spring (60), in order to prevent movement of the locking sleeve (30) beyond the removal position.

摘要: A chuck includes a driver disposed on a chuck body and in engagement with the jaws so that at least one of rotation and axial movement of the driver with respect to the body opens or closes the jaws. A first detent is disposed in the body in communication with the jaws. At least one of the jaws defines a catch at a predetermined position so that the catch engages the first detent when the jaws are at a predetermined position on the body with respect to a chuck bore.
