The various embodiments disclosed herein relate to arms or forearms of medical devices that are configured to couple with quick-release end effectors, quick-release end effectors for use with such medical devices, and arms or forearms coupled to such quick-release end effectors. Certain forearms and end effectors have magnetic couplings, while others have mechanical couplings, and further implementations have both magnetic and mechanical couplings.

An assembly allowing retraction of soft tissue away from a reference plane; the assembly including at least one retracting element each having a distal end with a formation allowing anchorage of the at least one retracting element. The assembly also includes a proximal end of the at least one retracting element capable of movement through at least one degree of freedom relative to the anchorage.

A surgical retractor is disclosed herein. In some embodiments, a surgical retractor includes a body extending from a proximal end to a distal end and having a first portion coupled to a second portion via a hinged connection, wherein the first and second portions are configured to rotate about a body axis; a first radiolucent tip coupled to a distal portion of the first portion; a second radiolucent tip coupled to a distal portion of the second portion; a holder coupled to one of the first or second portions; and a deformable member extending through the holder, wherein the deformable member is configured to be deformed to facilitate fixation of the surgical retractor at a desired location.

An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.

A pin removal tool includes a first arm member and a second arm member opposing the first arm member and connected to the first arm member at a pivot axis. The first and second arm members form a first interface therebetween at a first end of the tool configured to remove a headless pin and a second interface therebetween at a second end of the tool configured to remove a headed pin.

A method for performing an orthopaedic surgical procedure on a knee joint of a patient includes resecting a proximal end of a patient's tibia to create a resected surface of the patient's tibia and positioning a tibial paddle of a sensor module on the proximal end of the patient's tibia. The tibial paddle includes a sensor array generating sensor signals indicative of the joint force of the patient's knee joint. The method also includes performing a number of orthopaedic surgical steps while monitoring a display of the sensor module that provides a visual indication of the medial-lateral balance of the joint force of the patient's knee joint.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable is housing is configured to be releasably coupled to at least one of the shafts and an electrode assembly is configured to be releasably coupled to the disposable housing. The electrode assembly includes electrodes releasably coupled to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A tissue stop has a knife slot that aligns with the knife channel to receive the knife blade. An actuation mechanism advances the knife blade through the knife channel to cut tissue.

An electrocautery unit for connecting to a handle of an electrocautery device, the unit comprises a body, a light unit and an electrode. The body has a body proximal end and a body distal end, and a body axis extending lengthwise along the center of the body. The body’s proximal end comprises a connecting element for connecting said body to a handle having a handle axis extending lengthwise along the center of the handle, so that said body axis is coaxial with said handle axis when said body is connected to said handle. The light unit may be constructed and arranged to emit a light having a central axis coaxial with said body axis. The electrode comprises a proximate end connected to the body distal end, and an electrode tip at a distal said. When the electrode is connected to the body, the electrode lays outside of the body axis and extends into said body axis such that the electrode tip is within said body axis, wherein said light and said electrode tip are coaxial to said body axis and said handle axis.

An end effector assembly suitable for use with a forceps includes opposing first and second jaw members pivotably mounted with respect to one another. The first jaw member includes one or more pivot holes defined therein configured to receive a portion of a pivot pin therein. The end effector assembly also includes an electrically-insulative hinge configured to electrically isolate the first and second jaw members from one another including one or more pivot-hole locators having an aperture defined therein. The electrically-insulative hinge is attached to the first jaw member such that the one or more pivot-hole locators align with the one or more pivot holes of the second jaw member.

Treatment tool includes a fixed handle, a shaft extending distally from the fixed handle, a treatment portion projecting distally from the shaft and configured to treat biological tissue, a jaw pivotably rotatably with respect to the shaft and, with the treatment portion, configured to grasp the biological tissue therebetween, a movable handle extending proximally from the jaw and causing the jaw to open and close relative to the treatment portion by proximally approaching or separating from the fixed handle, and a first adjusting member provided on the movable handle and having an extension protruding toward the fixed handle and, when the movable handle is brought into close proximity to the fixed handle, abutting the fixed handle. Changing the amount (length) by which the extension of the first adjusting member protrudes from the movable handle, adjusts an amount of the stroke of the movable range of the movable handle.
