CUTTING TOOL
A cutting tool for severing a non-metallic material includes a holding element and a cutting element held on the holding element for cutting contact with the non-metallic material. A boundary region adjoins a holding material region of the holding element and a cutting material region of the cutting element. The precise severing of, for example, bone materials of human or animal origin, is possible in that a deformation resistance against an elastic deformation of the holding material region is greater than a deformation resistance against an elastic deformation of the cutting material region.
Surgical systems and tools for moving energy applicators in superimposed modes
A surgical tool may move a saw blade in a sagittal plane. The saw blade has a distal blade end with teeth. The surgical tool comprises a handpiece body and a carrier operatively attached to the handpiece body. The carrier is configured for oscillating movement about a pivot axis. A retainer is operatively attached to the carrier for concurrent movement and releasably secures the saw blade in the sagittal plane relative to the handpiece body. An actuator is coupled to the handpiece body to selectively oscillate the carrier relative to the handpiece body such that the retainer and the saw blade pivot back and forth about the pivot axis within the sagittal plane. An ultrasonic transducer is operatively attached to the handpiece body to selectively generate ultrasonic energy to resonate the saw blade such that the teeth at the distal blade end reciprocate proximally and distally within the sagittal plane.
SURGICAL CUTTING BLADE USING COMPOSITE MATERIALS
A guide is disclosed that operates to guide in the creation of a bone spur to facilitate harvesting a quadriceps tendon and includes an end having a width equal to a desired graft width with a terminal slope equal to a cutting angle desired. In use, the guide may be initially positioned parallel to the femur to form guide cuts in the patella. The guide is then rotated ninety degrees to allow an angled cut at the guide cut. The guide is again rotated, this time one hundred eighty degrees and a second angled cut made on the other guide cut. A final lateral cut is made and the bone spur may be lifted from the patella.
Surgical system and method for triggering a position change of a robotic device
The present disclosure relates to a surgical system for treating an anatomical structure according to a plurality of target planes and/or axes, comprising: a robotic device (1) comprising: an end effector (2) defining a current plane or axis, an actuation unit (11) coupled to the end effector (2), a tracking unit (3) configured to determine a pose of the current plane or axis, a control unit coupled to the tracking unit and configured to control the actuation unit (11) to align the current plane or axis of the end effector (2) with each one of the plurality of target planes and/or axes to treat the anatomical structure, the robotic device being operable in at least the following modes: a working mode wherein a treatment is being performed with the end effector constrained to one target plane or axis by the actuation unit, and a waiting mode wherein no treatment is being performed and the actuation unit is operable to move the end effector in alignment with another target plane or axis, wherein the control unit is further configured to: (a) determine that the robotic device (1) is in the waiting mode; (b) detect a triggering force applied to the end effector (2) and/or the actuation unit (11) in at least one first direction; (c) as a result of determination (a) and detection (b), trigger a position change of the end effector (2) by the actuation unit (11) to align the current plane or axis with a next target plane or axis.
SURGICAL INSTRUMENTS INCLUDING A SET OF CUTTING BLADES FOR PERFORMING AN OSTEOTOMY
Surgical instruments and methods for performing an osteotomy are disclosed herein. A surgical instrument includes a body with a distal end, a proximal end, a first surface, and a second surface. The surgical instrument can include cutting blades positioned on the first surface and the second surface. The surgical instrument can include columns of cutting blades positioned on the first surface and/or the second surface. The surgical instrument can include rows of cutting blades positioned on the first surface and/or the second surface.
DATA MODULES FOR SURGICAL INSTRUMENTS
In general, data modules for surgical instruments and methods of using data modules for surgical instruments are provided. In an exemplary embodiment, a data module is configured to be removably attached to a powered surgical tool such as an electrosurgical tool. The data module is a standalone device including electronic components that are configured to, with the data module attached to the electrosurgical tool, interact with the electrosurgical tool.
Surgical saw blade
A surgical saw blade has an upper surface and a lower surface, and includes a first end having right and left side edges, where the first end is configured to connect to an oscillating head of a powered saw. The saw blade also has a cutting end; and an elongated shank connecting the first end and the cutting end. The first end of the saw blade may be narrower than the shank, and a stopping surface may connect the first end to the elongated shank. The stopping surface is configured to engage the oscillating head of the powered saw, so as to ensure correct positioning of the saw blade relative to the oscillating head. The elongated shank of the saw blade may have an elongated hole through the shank, where the size and shape of the elongated hole are configured to optimize a resonant frequency and/or a dynamic stiffness of the saw blade. The cutting end of the saw blade may have a plurality of first teeth thereon, where each first tooth is mounted on a distal end of a tine. Each pair of adjacent tines is separated by a longitudinal slot, with a distal end of each longitudinal slot being bridged by a web connecting a corresponding pair of adjacent tines.
OSCILLATING TOOL
A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.
SURGICAL SAW BLADE FOR WEDGE OSTEOTOMIES
A surgical blade having an attachment base positioned at a proximal end and a wedge-shaped blade. The wedge-shaped blade includes a cutting tip having a first plurality of cutting teeth, which define a cutting edge along the distal end for starting an osteotomy. The wedge-shaped blade includes a second plurality of teeth positioned along rows. Each row is positioned at offset planes from adjacent rows along the wedge-shaped blade.
MULTIPLE THICKNESS SAW BLADE FOR PRECISION ORTHOPEDIC CUTS
A saw blade for use in an orthopedic procedure may have multiple regions of different thickness across the length of the saw blade. The saw blade may include at least one region that is comparatively thicker. The saw blade may also include at least one region that is comparatively thinner and position closer to an end of the saw blade having cutting teeth. In some configurations, the thicker region of the saw blade is an intermediate region located between two comparatively thinner regions. The intermediate thicker region can interface with a slot of a cutting guide while the comparatively thinner regions can be sides for engaging with a driver and controlling the kerf width of a bone cut made using the saw blade, respectively.
