A surgical system includes a robotic device, and a surgical tool coupled to the robotic device and comprising a distal end. The system further includes a neural monitor configured to generate an electrical signal and apply the electrical signal to the distal end of the surgical tool, wherein the electrical signal causes innervation of a first portion of a patient's anatomy which generates an electromyographic signal, and a sensor configured to measure the electromyographic signal. The neural monitor is configured to determine a distance between the distal end of the surgical tool and a portion of nervous tissue based on the electrical signal and the electromyographic signal, and cause feedback to be provided to a user based on the distance.

Devices and systems used to ablate tissue of a tumor using laser energy are disclosed. The devices and systems include a laser probe and a magnetic resonance (MR) safe temperature probe. The MR safe temperature probe includes an optical sensor. A bone anchor fixture separates the laser probe and the MR safe temperature probe to prevent interference in the MR safe temperature probe data. Proton Resonance Frequency (PRF) thermometry is used to model a temperature of a pixel of an MR image located adjacent the optical sensor. The modeled pixel temperature and the measured temperature are compared and monitored. Exceeding a threshold difference value causes an intervening action to occur.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit one or more signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the one or more signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply one or more instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element.

The invention proposes an automatic throat swab sampling system, which comprises an automatic to-be-tested person identity information checking and collection prompting unit, a to-be-tested person head positioning unit, a navigation positioning unit which enters the oral cavity of a to-be-detected person along with the tail end of the sample collection execution unit for collecting a throat image and determining depth information between a depth sensor and the throat of the to-be-detected person, a sample collection execution unit including a three-degree-of-freedom guide rail type device and a one-degree-of-freedom end execution mechanism, an automatic throat swab loading and unloading unit and a remote monitoring unit which are arranged on a working platform. In a throat swab collecting process, the real-time information of all units communicates with the remote monitoring unit, and medical staff monitors the collected person and all the units in real time through a computer in a remote safety room, so that measures can be taken timely to guarantee the safety and effectiveness of the whole process when an accident occurs. The system realizes the full-automatic throat swab collection process.

An apparatus for performing surgery includes a first link that includes a first end and a second end, a second link that includes a first end and a second end, and an end effector positioned at the first end of the first link. The first end of the second link is coupled to the first link by a hinge. The end effector traces along a surface, which may be spherical or hemispherical. A system that includes the apparatus and an imaging device, such as a CT scanner, is also described.

Ultrasound transducers adjust the B.sub.1.sup.+ and/or B.sub.1.sup.− field distribution in an MRI apparatus to improve the signal sensitivity and homogeneity at a region of interest. Approaches employed include strategic placement of field-altering features such as slots and/or dipoles along the exterior surface or, in some cases, the interior of the transducer. In various embodiments, the field-altering features are (or behave as) passive resonators.
