A phacoemulsification simulation apparatus includes a trigger device, at least two sensors, and a processor. The trigger device configured to apply, to fluid at an inlet of a needle of a phacoemulsifier, a pressure profile as a function of time in response to an input waveform. The at least two sensors are configured to measure a pressure of the fluid at respective points in the phacoemulsification simulation apparatus. The processor is configured to (a) drive the trigger device with the input waveform, thereby causing the trigger device to apply the pressure profile to the inlet while the fluid is aspirated via an aspiration line, (b) receive measurements of the pressure of the fluid from the at least two sensors, and (c) analyze an aspiration performance of the phacoemulsifier in response to the measurements.

Described are fibula malleolus caps and surgery devices with fibula malleolus caps. The fibula malleolus caps may be patient-specific fibula malleolus caps. The devices with patient-specific fibula malleolus caps overcome the sliding and rotational errors during fibula flap harvesting. A comparative clinical study demonstrates that the fibula malleolus cap enhances the accuracy of fibula flap harvesting, leading to accurate location and angulation of simultaneous dental implants.

A method for powered surgical stapling instrument rotation adjustment includes measuring a change in position of a first motor shaft of the surgical stapling instrument relative to a stored rotation verification position of the first motor shaft resulting from manual rotation of an adapter assembly of the surgical stapling instrument in relation to a handle assembly of the surgical stapling instrument, determining a distance traveled by a first drive assembly of the adapter assembly of the surgical stapling instrument resulting from the change in position of the first motor shaft, comparing the determined distance traveled to a first stored rotation verification position of the first motor shaft, determining if the compared distance falls into a predetermined acceptable range of rotation positions, and adjusting the position of the drive shaft if the compared distance is not within the predetermined range.

This disclosure relates to planning systems and methods. The planning systems and methods disclosed herein may be utilized for planning orthopaedic procedures to restore functionality to a joint, and may include one or more calibration objects for calibrating images of patient anatomy.

Disclosed is a system for determining a location and configuration of an expandable member. A flexible coil can be provided on a shape changing portion, such as an expandable portion, to measure a signal as the shape changes.

According to the present disclosure, a method of monitoring a patient on an operating room table is provided. The method comprises receiving image data captured by at least one image capture device; and determining a position of the patient relative to the operating table in dependence on the image data. A corresponding system, computer program and non-transitory memory are also provided.

A method is provided for navigating an endoscopic device through an anatomical luminal network of a patient. The method comprises: (a) commanding a distal tip of an articulating elongate member to move along a pre-determined path; (b) concurrent with (a), collecting positional sensor data and kinematics data; and (c) computing an estimated roll angle based on the positional sensor data and the kinematics data.

A splint device for guided robotic surgery, includes an arcuate splint body having first and second ends and opposing concave and convex surfaces. The splint body defines a plurality of holes spaced apart between the first and second ends, with each hole extending between the concave and convex surfaces. A tracking portion is engaged with the convex surface of the splint body between the first and second ends such that at least one of the holes is disposed between the tracking portion and each of the first and second ends. The tracking portion extends outwardly from the convex surface and has a kinematic mount engaged therewith.

A method and system for guiding knee replacement procedures, the method comprising receiving first data values from one or more sensors and one or more functional measurement devices, performing a reference measurement based on the first data values from the one or more sensors and the one or more functional measurement devices prior to a femoral cut, generating joint replacement recommendations based on the reference measurement, receiving second data values from the one or more sensors and the one or more functional measurement devices, performing a control measurement based on the second data values from the one or more sensors and the one or more functional measurement devices after a femoral cut based on the joint replacement recommendations, receiving third data values from the one or more functional measurement devices, and performing a pressure test that measures loading, balance, and kinematic behavior at medial and lateral condyles based on the third data values.

The bypass syringe is used in combination with an expandable or inflatable bladder or balloon that is circumferentially wrapped around a patient designed to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The bypass syringe is designed to pre-inflate the balloon, allow the balloon to relax based on how tightly the band is wrapped around the patient, and then be inflated with a volumetric amount of fluid. The bypass syringe's pre-inflation step will reduce complications caused by variabilities in band securement or tightness. A pre-inflation step combined with a venting of excess air step or controlled pressure inflation steps will absorb/take up/consume excess space caused by variability in band securement and help to reduce complication caused by securement variability.
