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.

A cup remover instrument assembly for removing an acetabular cup in a revision hip procedure comprising: a positioning member supporting a cutting assembly having a cutting blade and a detachable drive member for selectively rotating the cutting assembly to cut around a cup to detach the cup from a patient's natural acetabulum. In embodiments, the positioning member is sized and configured to operate in a main incision, while the drive member is sized and configured to operate in a portal incision. In embodiments, the cutting blade is detachable for use in selecting blades for cup sizes. In embodiments, the cutting blade is selectively extendable from the cutting assembly. In other embodiments, the cutting blade is hemispherical and is rotated by a power driver.

This disclosure relates to reaming assemblies and methods for repairing bone defects. The reaming assemblies disclosed herein may be utilized for removing bone prior to positioning a graft and/or implant at a surgical site.

A drill assembly including a cutting tool slidably movable along a longitudinal axis of the drill assembly and drivable to cut an object. In an active configuration, a pressure loaded drive control assembly transfers energy from a motor to the cutting tool to drive the cutting tool. In an inactive configuration, the pressure loaded drive control assembly prevents energy transfer from the motor to the cutting tool. A biasing member of the pressure loaded drive control assembly is configured to bias the pressure loaded drive control assembly in the inactive configuration. Depressing the cutting tool against the object moves the cutting tool along the longitudinal axis and moves the pressure loaded drive control assembly to the active configuration. The biasing member returns the pressure loaded drive control assembly to the inactive configuration when the cutting tool is no longer depressed against the object.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.
