A cautery pen tip accessory cover comprises a cylindrical member that can receive a cautery pen in a first end and the tip of the cautery pen can extend from a second opposite end when the cover is in a retracted configuration. The cylindrical member has an opened lateral exposure that allows the feel of the cautery pen therethrough. A cover exposure opening in the cylindrical member to provide access to a trigger of the cautery pen when the cautery pen tip cover is in the retracted configuration. A resilient member urges the cautery pen tip cover to the non-retracted configuration where access to the cautery pen trigger is prevented. The cylindrical member is easily retracted by a finger ring configured permanently into the cylindrical member, allowing easy retraction of the cover by the operator squeezing the cover to a resistance bar stabilization system accessory configured over the cautery pen.

Devices and methods are disclosed for preventing injury to a target tissue in proximity to the heart. The methods may include the use a device to externally manipulate the heart to move a portion of the heart away from the target tissue. The methods may also include applying therapy to the heart with the device.

The present disclosure is directed to a planning and navigation method. The planning and navigation method includes obtaining a plurality of images, rendering the plurality of images in three dimensions, automatically segmenting the plurality of images to demarcate a target area, and automatically determining a treatment plan based on the target area. The planning and navigation system also includes obtaining an ultrasound image of a scan plane including the target and obtaining a fiducial image of a fiducial pattern disposed on an ultrasound device using an image capture device on a surgical device. The obtained fiducial image is corrected for lens distortion and a correspondence between the fiducial image and a model image is found. After which a camera pose is a position of the surgical device is transformed to model coordinates. Then the ultrasound image and a virtual image of the surgical device is displayed based on the model coordinates to allow a surgeon to navigate the surgical device to the target using the displayed ultrasound image and the virtual image and treating the target based on the treatment plan.

Proposed is a local cooling anesthesia device for spraying a coolant on a treatment site. The local cooling anesthesia device includes a housing which forms an outward form and from which the coolant is sprayed and a spraying unit installed in the housing to spray the coolant. The device also includes a cooling temperature regulator connected to the spraying unit to apply thermal energy to the sprayed coolant for temperature regulation and a control unit connected to the cooling temperature regulator to control the cooling temperature regulator. The cooling anesthesia device has functions of measuring and regulating the temperature of the coolant, and thus can apply the coolant to the treatment site within a safe temperature range according to the purpose of treatment, thereby enabling a desired treatment purpose such as local anesthesia to be safely and rapidly accomplished without side effects such as cytoclasis.

A first subassembly includes a body and an ultrasonic blade. A second subassembly is configured to removably couple with the first subassembly and includes a first clamp arm and a first clamp arm actuator. The first clamp arm is configured to be located on a first side of the longitudinal axis of the body, and the first clamp arm actuator is configured to be located on a second side of the longitudinal axis, when the second subassembly is coupled with the first subassembly. The third subassembly is similar to the second subassembly except that the second clamp arm of the third subassembly is configured to be located on the second side of the longitudinal axis of the body when the third subassembly is coupled with the first subassembly.

Apparatus and techniques for blocking radiation in a medical environment are described. In one or more embodiments, a lock-block shield device includes a base that is configured to adhesively couple to an object associated with a patient. In some embodiments, the base includes a lock mechanism for securing a work piece that has a generally tubular shape. A shield that is configured to at least partially block transmission of radiation can be coupled to the base in a releasable manner. For example, a clasp is used to secure the base and shield together. In embodiments, a ball and socket joint couples the shield and base to permit, for example, the shield to pivot and articulate with respect to the base.

The instant disclosure relates to electrophysiology catheters for tissue ablation within a cardiac muscle, for example. In particular, the instant disclosure relates to an electrophysiology ablation balloon catheter with a combination of coated and uncoated surfaces for focusing ablation energy at a desired portion of tissue.

A robotic surgical arm including a receiver configured to receive wireless communications from a robotic surgical instrument attached to the robotic surgical arm and a shield including a plurality of fingers each having a common shape and a connector being in contact with each of the fingers. When the connector is electrically connected to ground, the shape, dimensions and arrangement of the fingers causes attenuation of the transmission of electric fields through the shield.

Certain aspects of the present disclosure provide methods and apparatus for managing an esophagus of a subject during a medical procedure, such as cardiac tissue ablation or bronchial tissue ablation. Managing the esophagus may include displacing the esophagus, imaging the esophagus, and/or measuring temperature at one or more locations inside the esophagus. One example esophageal management system generally includes a tube configured for insertion through a mouth and into the esophagus of the subject. The tube generally includes a first port located at a proximal end of the tube and in fluid communication with a distal portion of the tube via a first path, a second port located at the proximal end of the tube, and a third port located between the proximal end of the tube and a distal end of the tube and in fluid communication with the second port via a second path.
