A system for dilating the sinus ostia with a device including a series of elongated members, each having a central channel and increasing outer diameters where the members are positioned one over the other such that the members are advanced to incrementally dilate the sinus ostia. The central channels of each member allow for various procedures to be performed including, for example, the application of wireless energy (e.g., ultrasonic, RF, etc.) to the sinus ostia, the introduction of an irrigating fluid and aspiration from the sinus ostia, and the introduction of a drug to the sinus ostia.

Embodiments of the present disclosure are directed to systems and methods for device exchange in an endoscopic procedure. In one implementation, a system for device exchange in an endoscopic procedure includes an elongated device having a slit extending from a distal end to a proximal end of the elongated device, a main block, and an adapter. The main block is configured to be affixed to a port of an endoscope. The main block includes a main channel for receiving a guidewire and the elongated device. The adapter can be engaged with the main block and configured to merge the guidewire into the elongated device. The adapter includes a working channel for receiving the elongated device and a working member raising from an inner wall of the working channel. When the elongated device passes through the working channel, the working member wedges open a portion of the slit of the elongated device such that a portion of the guidewire merges into the elongated device through the opened portion of the slit.

A control device for a dental microscope includes a control module and a driving module. The dental microscope includes an adjustment knob operable to adjust an operating parameter of the dental microscope. The control module includes at least one pedal and a signal transmitter coupled to the pedal. The signal transmitter generates and outputs a control signal upon the pedal being pressed. The driving module includes a motor connected to the adjustment knob, and a signal receiver configured to receive the control signal and to activate the motor to turn the adjustment knob according to the control signal.

An instrument driving mechanism includes an instrument drive assembly (140) including a first set of wheels (136) coupled to a first end portion and a second set (138) of wheels coupled to a second end portion opposite the first end portion. The first set of wheels is configured to engage an elongated instrument (104) therein such that a rotation plane of the first set of wheels is coplanar with a longitudinal axis of the instrument. The second set of wheels is configured to engage the elongated instrument therein such that a rotation plane of the second set of wheels is obliquely oriented with the longitudinal axis of the instrument wherein motion of the instrument is controlled by controlling rotations of the wheels. The instrument drive assembly mounts to a mounting position (149) of a medical device that permits the instrument to pass therethrough and is configured to fix a position of the instrument drive assembly to enable positioning of the instrument.

The present application relates to the technical field of oral care devices, and discloses an oral endoscope, the oral endoscope comprising: a housing; an image acquisition module, which is fixedly mounted within the housing and which is used for acquiring an external image through the housing, the image acquisition module comprising at least two camera units, which are relatively positionally calibrated and which are used for acquiring three-dimensional image information; an illuminating unit, which provides illumination for each camera unit; a wireless communications module, which is used for wirelessly communicating with an external device and for sending image information, which is acquired by the image acquisition module, to the external device. The oral endoscope may acquire three-dimensional images at various positions in an oral cavity; the oral endoscope need not scan various positions in the oral cavity according to a set sequential requirement, thus the operational requirements thereof are low, and the present invention may be used for self-serviced dentition molding by an ordinary user.

An imaging device according to an embodiment of the present technology includes a first polarization section, a second polarization section, a rotation control section, and a generation section. The first polarization section irradiates a body tissue with polarization light of a first polarization direction. The second polarization section extracts a polarization component of a second polarization direction that intersects with the first polarization direction, from beams of reflection light that are the polarization light reflected by the body tissue. The rotation control section that rotates each of the first polarization direction and the second polarization direction while maintaining an intersection angle between the first polarization direction and the second polarization direction. The generation section that generates an image signal of the body tissue on the basis of the polarization component of the reflection light extracted by the second polarization section in accordance with rotation operation performed by the rotation control section.

An endoscope includes a prism disposed in a distal end portion of an insertion section and configured to change a direction of a field of view in an upward, downward, leftward, or rightward direction, an operation lever disposed in an operation section, being turnable from a neutral position around a third axis and a fourth axis that are perpendicular to each other, and including a second longitudinal axis, a cylindrical member disposed such that turning around a fourth axis of the lever is transmitted and configured to turn around the fourth axis by inclining the operation lever, a transmission wire configured to transmit turning around a first axis to the prism in response to an inclination operation around the third axis of the lever, and gears configured to transmit turning around a second axis to the prism in response to a turning operation around the fourth axis.
