A surgical apparatus generates energy that is input onto an appliance. The appliance is one of an implant to be implanted in human or animal bone tissue by the input of the energy, and of a tool being an ultrasonic bone cutting and/or punching tool for cutting and/or punching living human or animal bone tissue by input of energy onto the implant in a surgical operation. The apparatus includes a control device and at least one handpiece, the handpiece being equipped to be held by a surgeon during the operation and to couple the energy into the appliance. The apparatus further includes a reading device equipped to read out, from an appliance data carrier, appliance data dedicated to the appliance. The control device checks, depending on the appliance data, whether the handpiece is suitable for the appliance and chooses operating parameters depending on the appliance data.

The handpiece includes; an outer housing of a bar shape; a cylindrical core inserted into the outer housing and having an air hole and a water hole; pipes respective inserted into the air hole and the water hole of the core; a rotor made with a cylindrical magnetic material and inserted into the core; cylindrical support rings forcedly fit to both sides of transfer shafts of the rotor; a pair of bearings respectively disposed at the front side and the rear side of the support rings; a coupling disposed in front of the rotor; a front housing joined to the front of the outer housing; a front cap disposed at the rear of the core; a rear cap disposed at the rear of the front cap and having a power supply terminal disposed at one side thereof; and a rear housing joined to the rear of the outer housing.

A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.

A tool for a bone implant includes a sleeve and a transmission rod including a transmission member disposed on an end of a shaft. Another end of the shaft is located outside of the sleeve. The transmission member is received in the sleeve and includes a first compartment and a plurality of first teeth surrounding the first compartment. A drilling rod includes a second compartment and a plurality of second teeth surrounding the second compartment. A coupling portion is disposed between the second compartment and a bit. The coupling portion is coupled with the sleeve. The bit is located outside of the sleeve. Two magnets are disposed in the first and second compartments, respectively. Two same poles respectively of the two magnets face each other.

A dental implant drill bit is internally irrigated and guided by markings. The dental implant drill bit also uses a collar to stop the drill. Any size of implant hole required for placing an implant directly corresponds with one size of implant drill bit, thus allowing a single drill bit osteotomy. Using the internally irrigated dental implant drill reduces the time and number of drill bits during osteotomy.

A surgical tool that includes a nose through which a cutting accessory extends. The nose is formed with an enclosed channel through which irrigating fluid is flowed. The enclosed channel has a helical shape such that as the channel extends longitudinally along the nose, the channel curves around the nose and the cutting accessory disposed in the nose.

A medical drill bit comprises an accommodating slot disposed concavely on a main body of the medical drill bit, a separate board disposed in the accommodating slot to separate the accommodating slot into a first slot and a second slot, and a lid engaging with the separate board and covering the accommodating slot. The lid and the separate board do not rotate with the main body when the main body in rotation. The accommodating uses to fill with cooling liquid which able to be pumped out from the accommodating slot, and fresh cooling liquid is able to inject into the accommodating slot for cooling the drill bit in rotation.

An orthopaedic tool cluster clamp includes a pair of jaws held together and defining a distance therebetween, the jaws being movable relative to one another to adjust the distance; a connector holding the jaws together, with actuation of the connector adjusting the distance between the jaws; a cam base including a ramped portion statically associated with one of the jaws; and a cam lever pivotally connected to the connector about an axis of rotation and held against the cam base. The cam lever defines a profile such that rotating the cam lever along the ramped portion and pivoting the cam lever about the axis of rotation both cause actuation of the connector.

A surgical drill type cutting tool includes a shank and an active portion extending in the extension of the shank, with chip areas extending along the active portion, and a ring surrounding a part of the active portion, an inner surface of the ring engaging the active portion without closing off the chip areas, allowing irrigation fluid to provides useful irrigation over most of the length of the active portion of the surgical drill bit.

Disclosed herein is a surgical device. The surgical device includes a cutting burr, a flexible/deflectable shaft, an elongated fluted shaft, a sheath, and an outer tube. The cutting burr has a fluted extension. The flexible/deflectable shaft has a distal end and a proximal end, the distal end is configured to be connectable to the fluted extension of the cutting burr. The elongated fluted shaft is configured to be connectable to the proximal end of the flexible shaft. The sheath is configured to receive all or portion of the flexible shaft and the elongated fluted shaft. The outer tube is configured to receive the sheath such that there is enough space for fluid irrigation between the outer tube and the sheath.
