A tissue splitting device for splitting a harvested soft tissue to provide a layer of tissue having a uniform thickness and methods for tissue transplantation using uniform layers of tissue.

Sterile connectors for robotic or robot-assisted surgery and related systems and methods can be used to establish a sterile barrier between a non-sterile robot arm and a surgical site. More particularly, a sterile connector can include a first component connector to couple to a distal end of a robot arm, a second component connector to couple to an end effector, and a sterile drape extending from the sterile connector. The sterile drape can drape the robot arm and can maintain a sterile barrier around the robot arm throughout the course of a surgical procedure. In this manner, an end effector can be swapped out during the procedure without the need to re-drape or re-establish the sterile surgical field. In some embodiments, the sterile connector can facilitate the passage of electrical signals and/or light between the sterile connector and at least one of the robot arm and end effector.

A surgical saw apparatus, includes: A) a housing; B) a drive unit with a drive axle having a central axis; C) a deflection device, including: a connecting rod that is arranged movably in the housing, with a longitudinal axis, with a rear section and with a front section with members for a fixation of a sawblade; an eccentric shaft with at least one first section, which is arranged coaxially with the central axis of the drive axle and is connected with the drive axle, and with a second section which is eccentric relative to the first section, wherein the rear section of the connecting rod is a bearing for the eccentric second section of the eccentric shaft, and the front section of the connecting rod is a fixation device for a sawblade; and a guiding device for the connecting rod, wherein D) the guiding device includes first members for a limitation of a movement of the connecting rod, which are movable relative to the housing and which force a translational movement of the connecting rod coaxially with the longitudinal axis of the connecting rod, and E) the guiding device includes second members for a limitation of a movement of the first members, which are movable relative to the housing and which force a movement of the first members transversally to the longitudinal axis of the connecting rod.

A system and method for tracking position and orientation of a surgical tool during a surgical procedure and providing feedback to a user are described. For example the system includes a surgical tool configured to perform at least a portion of the surgical procedure, a tracking system configured to monitor and record position information related to the surgical tool, a processing system, and a display. The processing system can be configured to receive the position information, determine optimal position information for the surgical tool during the surgical procedure, compare the received position information against the optimal position information to determine a conformance level for the user, and generate a user performance record. The display can be configured to receive and display the user performance record.

A surgical cutting tool for keyhole surgery comprises: a handle 2 at a proximal end of the tool; an elongate member 4 extending from the handle to a distal end of the tool; and a saw 6 at the distal end of the tool, the saw being supported by the elongate member 4. The elongate member 4 has a length allowing for insertion of the saw 6 into the body by a distance of at least 150 mm. The tool is arranged for insertion of the saw 6 into the body during keyhole surgery; and the saw 6 is able to cut bone when pressed against the bone.

A tissue splitting device for splitting a harvested soft tissue to provide a layer of tissue having a uniform thickness and methods for tissue transplantation using uniform layers of tissue.

A passive end effector of a surgical system includes a base connected to a rotational disk, and a saw attachment connected to the rotational disk. The base is attached to an end effector coupler of a robot arm positioned by a surgical robot, and includes a base arm extending away from the end effector coupler. The rotational disk is rotatably connected to the base arm and rotates about a first location on the rotational disk relative to the base arm. The saw attachment is rotatably connected to the rotational disk and rotates about a second location on the rotational disk. The first location on the rotational disk is spaced apart from the second location on the rotational disk. The saw attachment is configured to connect to a surgical saw including a saw blade configured to oscillate for cutting. The saw attachment rotates about the rotational disk and the rotational disk rotates about the base arm to constrain cutting of the saw blade to a range of movement along arcuate paths within a cutting plane.

A method for the removal of a bone insert for a shoulder prosthesis, which provides for: forming a hole inside a proximal bone portion; inserting in the hole an operating end of an instrument provided with a moveable cutting element deep-cutting a distal base of the bone insert, by rotating the instrument through 360 degrees around its longitudinal axis; removing the instrument from the hole; inserting and fixing a pin element inside the hole; milling the bone insert; removing the bone insert and the pin element attached thereto.

A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.
