Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

A surgical drain for monitoring an internal site in a patient. The surgical drain can include an outer flexible tube, a first tube, and a second tube. The outer flexible tube can include a plurality of ports extending from a proximal end to a distal patient end. The first tube can be inserted within the first port, having at least one lumen side extending therethrough in fluid communication with a collection device. The first tube is configured to drain fluid from an internal site in the patient to the collection device. The second tube can extend through a second port having a camera at the distal patient end of the second tube.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

A system for controlling a robotic tool includes a memory that stores instructions and a processor that executes the instructions. When executed by the processor, the instructions cause the system to perform a process that includes monitoring sequential motion of tissue in a three-dimensional space. The process also includes projecting locations and corresponding times when the tissue will be at projected locations in the three-dimensional space. An identified location of the tissue in the three-dimensional space is identified based on the projected locations. A trajectory of the robotic tool is set to meet the tissue at the identified location at a projected time corresponding to the identified location.

A teleoperated system comprises a display, a master input device, and a control system. The control system is configured to determine an orientation of an end effector reference frame relative to a field of view reference frame, determine an orientation of a master input device reference frame relative to a display reference frame, establish an alignment relationship between the master input device reference frame and the display reference frame, and command, based on the alignment relationship, a change in a pose of the end effector in response to a change in a pose of the master input device. The alignment relationship is independent of a position relationship between the master input device reference frame and the display reference frame. In one aspect, the teleoperated system is a telemedical system such as a telesurgical system.

A method for disengagement detection of a surgical instrument of a surgical robotic system, the method comprising: determining whether a user's head is unstable prior to disengagement of a teleoperation mode; determining whether a pressure release has occurred relative to at least one of a first user input device or a second user input device for controlling a surgical instrument of the surgical robotic system during the teleoperation mode; and in response to determining the user's head is unstable or determining the pressure release has occurred, determining whether a distance change between the first user input device and the second user input device indicates the user is performing an unintended action prior to disengagement of the teleoperation mode.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to obtain one or more operating characteristics of an instrument located in a surgical space; obtain one or more anatomical characteristics associated with the surgical space; and direct a computer-assisted surgical system to automatically perform, based on the based on the one or more operating characteristics of the device and the one or more anatomical characteristics associated with the surgical space, an operation with the instrument located in the surgical space.

The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined. The desired relationship between markers may then be programmed into, for example, the detection device. Next, actual physical reduction and/or manipulation of the bone may begin. During the manipulation procedure, the orientation of the markers may be continuously monitored and when the markers substantially align with the virtual or simulated orientation of the markers in the desired restored orientation, an indicator signal is transmitted.

Surgical systems and methods are provided that utilize augmented reality navigation and visualization techniques for transferring aspects of a preoperative surgical plan to an actual surgical site. The surgical systems and methods may be utilized to achieve accurate alignment of a surgical positioning object, such as a guide pin for guiding surgical reaming procedures, between the preoperative surgical plan and the intraoperative anatomy associated with the actual surgical site. Augmented reality may be utilized to achieve visualization of both an entry point and a drilling trajectory of the surgical positioning object in a manner that avoids occluding the intraoperative anatomy during the procedure.

Disclosed is a method for providing guidance to a user on where to arrange an object of interest in an operating room. The method includes obtaining a spatial pose of an item arranged within the operating room and obtaining a requirement on a spatial relationship between an object of interest and the item. The method also includes determining (a) a first spatial portion in which the object of interest is recommended to be arranged, the first spatial portion being larger than the object of interest, and/or (b) a second spatial portion in which the object of interest is not allowed to be arranged. Moreover, the method includes triggering display of a visualization of the first and/or second spatial portion to guide a user on where to arrange the first object of interest in the operating room.
