Surgical methods and devices that facilitate registration of arthroscopic video to preoperative models are disclosed. With this technology, a machine learning model is applied to diagnostic video data captured via an arthroscope to identify an anatomical structure. An anatomical structure in a three-dimensional (3D) anatomical model is registered to the anatomical structure represented in the diagnostic video data. The 3D anatomical model is generated from preoperative image data. The anatomical structure is then tracked intraoperatively based on the registration and without requiring fixation of fiducial markers to the patient anatomy. A simulated projected view of the registered anatomical structure is generated from the 3D anatomical model based on a determined orientation of the arthroscope during capture of intraoperative video data. The simulated projected view is scaled and oriented based on one or more landmark features of the anatomical structure extracted from the intraoperative video data.

A laser treatment system includes a sensor configured to detect a targeted therapy region. A processing unit is configured to generate a treatment path that consists of sequentially arranged laser spots to enable the treatment path to fully encompass a targeted therapy region to receive laser therapy. A steering device is alerted to move to a plurality of positions based on the treatment plan generated by the processing unit. A treatment laser provides laser therapy to the plurality of positions and targeted therapy region based on the treatment plan generated by the processing unit.

Disclosed herein are systems for implanting anchors and method of use thereof. The systems and methods can include an anchor punch, an anchor inserter, and a controller. The anchor punch can include an anchor punch sensor. The anchor inserter can include an anchor inserter sensor. The controller can be in electrical communication with the anchor punch sensor and the anchor inserter sensor. The controller can be operative to perform operations that include receiving an anchor punch sensor signal from the anchor punch sensor, recommending a number of anchors to be implanted in the bone based on a first estimate of the bone quality, receiving an anchor inserter signal from the anchor inserter sensor, and recommending a number of additional anchors to be implanted in the bone based on a second estimate of the bone quality.

A surgical instrument with pressure sensing and vision feedback functions has an instrument body and a piezochromic device. The instrument body includes a work piece with a visible surface. The piezochromic device is disposed on the visible surface of the work piece of the instrument body and performs color change when the piezochromic device senses pressure. Therefore, when a doctor performs surgery using the surgical instrument, the doctor can directly see the piezochromic device. When the piezochromic device contacts other surgical instruments or presses organs or tissues within a patient's body, the piezochromic device will change color when the piezochromic device senses the pressure enabling the doctor to adjust the surgical instrument accordingly.

A method for treating tissue through a branched luminal network of a patient is provided. A pathway to a point of interest in branched luminal network of a patient is generated. An extended working channel is advanced transorally into the branched luminal network and along the pathway to the point of interest. The extended working channel may be positioned in a substantially fixed orientation at the point interest. A tool is advanced though the extended working channel to the point of interest. Tissue at the point of interest is treated.

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

A basket apparatus is described that assists in removing objects from within a patient. The apparatus includes a number of pull wires, each pull wire physically coupled to a different capstan that individually actuates one of the pull wires. The apparatus also includes an outer support shaft itself including a number of channels through which the pull wires traverse. The portions of the pull wires extending out of the outer support shaft form a basket of adjustable size, shape, and position. The pull wires are attached together at a tip located at a distal end of the basket apparatus. By controlling the actuation of the various pull wires, the basket's shape, position size can be manipulated to reposition the basket around an object located within a patient, independent of or in conjunction with motion of the remainder of the apparatus or an associated endoscope.

Methods and systems for outputting depth data during a medical procedure on a patient. Depth data is outputted, representing at least one of relative depth data and general depth data. Tracking information about the position and orientation of a medical instrument and depth information about variations in depth over a site of interest are used. Relative depth data represents the depth information relative to the position and orientation of the instrument. General depth data represents the depth information over the site of interest independently of the position and orientation of the instrument.

A method is disclosed. The method includes delivering staples from a surgical staple cartridge of a surgical instrument to a first tissue during a first procedure; removing the surgical staple cartridge from the surgical instrument; and delivering radio-frequency energy from a radio-frequency cartridge of the surgical instrument to a second tissue during a second procedure.

An ultrasonic surgical instrument is disclosed including an ultrasonic blade, an ultrasonic transducer operably coupled to the ultrasonic blade, and a control circuit. The ultrasonic transducer is configured to transmit ultrasonic vibrations to the ultrasonic blade based on a drive signal. The control circuit is configured to provide the drive signal to the ultrasonic transducer, monitor a vibration frequency of the drive signal, and modify the drive signal based on a change in the vibration frequency of the drive signal.
