The invention is directed towards tools for use in performing surgery or examination via the oral cavity, in particular in the region of the oral cavity, oropharynx, larynx, and hypopharynx, devices and systems incorporating these tools, and procedures using these tools. More specifically, the tools, devices, systems and procedures are directed towards Transoral Robotic Surgery or any non-robotic transoral surgical approach.

Cheek and lip expansion devices including an upper frame portion configured to extend about an upper dental arch, and a lower frame portion configured to extend about a lower dental arch. The upper and lower frame portions may each include first and second side members, each with anterior and posterior regions. An upper connecting member may extend between the anterior regions of the upper side members. A lower connecting member may extend between the anterior regions of the lower side members. The posterior regions of the upper and lower side members on respective sides of the frame are joined to one another to form a bendable radius that resists bending at a distinct point. The bendable radius on opposed sides permits the frame to be collapsed top to bottom. The frame may be collapsible side-to-side. A posterior crossbar may be provided extending between the posterior regions of the side members.

An example apparatus for use in obtaining digital open bite registration is described herein. The apparatus can include a bite fork configured to fit in a subject's mouth. The bite fork can include at least one molar pad and at least one incisor pad, each of the at least one molar pad and the at least one incisor pad having respective upper and lower bite surfaces. The apparatus can further include a lingual band extending between the at least one molar pad and the at least one incisor pad.

The present invention relates to a cough treatment device, and in order to treat coughs, which are the main symptoms of a respiratory disease, provided is the cough treatment device having: a horizontal bar formed in a bar shape so as to press, while being bitten by the upper and lower teeth, the tip of the tongue such that the tongue enters the mouth, thereby expanding an airway; and wing parts for guiding air flowing into the mouth such that the air passes the surface of the mouth, thereby buffering air flowing into the airway and changing the temperature of the air and, simultaneously, allowing moisture in the air.

Systems and methods for measuring analytes in fluid samples are disclosed. The systems and methods employ test strips which are generally comprised of a substrate, at least one electrical connection, at least one sensing chemistry and at least one additional layer. The test strips can be batch calibrated.

Disclosed herein are multiple cannulas defining a lumen sized and dimensioned to receive one or more medical instruments, an inflatable outer membrane attached to an outer surface of the cannula, and at least one activator that reversibly activates the cannulas to push a fluid contained in the cannulas into the outer membrane to fill or pressurize the outer membrane. Also disclosed are methods for operating these cannulas.

Provided is a tongue separation device including: a body unit including a contact surface fixing a tongue; a support unit arranged at one end portion of the body unit and supporting the body unit from outside a mouth; a tooth mounting unit arranged at one surface of the support unit adjacent to a first region of the body unit, mounting the teeth in a state where the body unit is inserted into the mouth, and including an upper surface mounting upper teeth among the teeth and a lower surface mounting lower teeth among the teeth; and a tongue position checking unit including an opening formed at the support unit to check a position of the tongue from outside the mouth, wherein a first portion of the contact surface of the body unit adjacent to the one end portion of the body unit is arranged over a virtual extension surface that passes through a center of the support unit and crosses between the upper surface and the lower surface of the tooth mounting unit, and a second portion of the contact surface of the body unit adjacent to the other end portion of the body unit is arranged under the virtual extension surface.
