An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.

An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

Disclosed is an assembly for holding a tool. The assembly may selectively reduce and/or eliminate vibrations received and felt by a user. Reducing vibrations may reduce or eliminate chatter at a working end of a tool.

A chuck assembly for a medical device is provided. The chuck assembly includes a mounting base structured to couple to a tool; a housing coupled to the mounting base; and a cam sleeve within the housing and movable with respect to the housing between a locked position and an unlocked position, the cam sleeve having an annular base, an arm extending from the annular base, and a cam extending laterally from the arm.

A protected drill is disclosed. The drill may include a housing, and a drill bit disposed at a distal end of the drill. The drill may have a rotatable drive shaft that is configured for coupling to a driver and a main shaft portion extending in a longitudinal direction through the housing. The drill may further include an angled tip portion disposed at a distal end of the drill, and the angled tip portion may be angled with respect to the longitudinal direction and define a drilling axis of the drill bit. The drill may further include a mechanism configured to transfer a rotational force applied to drive shaft through the angled tip portion to the drill bit. The drill may further include a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating.

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.

Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.

A drill bit comprises a shank extending along an axis and an interface comprising at least one outermost drive portion spaced at a first interface distance from the axis. The drill bit further comprises a resilient arm extending from a proximal end of the shank. The resilient arm comprises an outer arm surface facing away from the axis and a retention surface facing toward a distal end of the shank. The retention surface may be radially aligned about the axis with respect to the outermost drive portion. The resilient arm is movable between: a first position where the outer arm surface is spaced from the axis at a first arm distance greater than the first interface distance, and a second position where the outer arm surface is spaced from the axis at a second arm distance less than or equal to the first interface distance.

The device of the present disclosure is configured for laparoscopic use, particularly to insert a fastener into a plate at an angle of up to 180° from the plane of insertion. The device is further configured to carry a plurality of fasteners, a tightening tool, a cutting device, and tweezers simultaneously to facilitate a rapid procedure while lessening the chance of infection by limiting the amount of times the device must be removed and re-inserted.

A surgical device (600) includes an articulating portion (604) for navigating the device within a bodily cavity. The articulating portion (604) includes an articulating sheath (1000) and an articulating torque transmission wrist within the articulating sheath (1000). The articulating sheath (1000) may define one degree of freedom or two or more degrees of freedom. The articulating portion (604) may be part of a surgical device shaft (602) connected to an end effector (603) rotated by an internal torque transmission shaft including the articulating torque transmission wrist. The articulating portion (604) may be articulated while the torque transmission shaft is being rotated.
