Irrigation and/or aspiration devices and methods may be configured to aspirate and irrigate alone, sequentially, or concurrently. The devices and methods may provide a base with a removable head, and adapted for partial or complete separation of the irrigation and aspiration functions. The devices and methods can be configured to aspirate and/or irrigate the nasal and sinus cavities. The devices and methods may be manually and/or automatically controlled. The devices and methods may include removable, and/or replaceable, and/or refillable, and easily cleanable reservoirs for aspirant and irrigant. The device head and/or aspirant reservoir may comprise a diagnostic device, i.e., test device and/or container after use of the devices and methods.

A nose cleaning swab system including a cleaning swab having a handle and an auger swab head. The auger swab head has a swirled profile including a plurality of spaced ribs. As a user twists the handle, the auger swab head efficiently removes material out of a bodily orifice when the auger swab head is inserted into the bodily orifice such as a nose. The auger swab head is tapered from a tip to a base where the auger swab head is connected to the handle creating a continuous one-piece the cleaning swab.

An irrigation and aspiration system is disclosed. The system can be configured to aspirate and irrigate alone, sequentially or concurrently. The system can be configured to aspirate and irrigate the nasal cavity. The system can be manually controlled. The system can have removable and easily cleanable reservoirs for aspirant and irrigant.

Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.

An array of sensors may be used to perform touchless registration of landmarks of a patient's face before an ENT procedure in order to associate those landmarks with pre-operative images in three-dimensional space, which is required for image guided surgery features such as navigation. Touchless or light-touch registration may improve accuracy by avoiding the need for substantial pressing against a patient's skin, which may deform and thereby introduce erroneous registration data. A sensor may also be implemented in forms other than an array such as handheld probe having a single sensor as opposed to an array.

One embodiment provides a system, method, and wireless endoscope for performing internal imaging. A first portion of a wireless endoscope including at least a lens and a light emitter for physical connection to a second portion of the wireless endoscope is received. The first portion is interchangeable. The first portion is inserted into a body while the second portion remains outside the body. The wireless endoscope is powered on in response to receiving user input from a user. A distal end proximate the lens is illuminated utilizing a light in communication with the light emitter. Video inside the body is captured utilizing a camera in communication with the lens. The video is wireless communicated to a receiver associated with a display.

An aspirator including an impeller driven by a driving component to create a suction through a fluid inlet; a housing surrounding the impeller; and a disposable tip. The disposable tip is removeably couplable to the housing at the fluid inlet, defines a fluid intake port in fluid communication with the outside environment and the fluid inlet, and has an aspirated bodily fluid collection region that collects and retains aspirated bodily fluids drawn into the disposable tip by the impeller's suction.

An apparatus includes a body, a guide member, an elongate translating member, an actuator, and a force measuring feature. The guide member is coupled to and extends distally from the body, and defines a longitudinal axis. The elongate translating member is operatively coupled with the body and is slidably disposed relative to the guide member. The elongate translating member is configured to translate relative to the body between a retracted position and an extended position for accessing an anatomical passageway. The actuator is coupled to the elongate translating member, and is selectively movable relative to the body to actuate the elongate translating member between the retracted and extended positions. The force measuring feature is operatively coupled with the actuator, and is configured to detect and measure an axial force exerted on the elongate translating member by the actuator when the elongate translating member moves between the retracted and extended positions.

A hygiene device for use with a body orifice of a living being, the hygiene device including a head adapted for use in the body orifice, the head being formed of one or more absorbent materials that are adapted to collect substances from the body orifice and a handle connected to the head to enable the head to be inserted into and removed from the body orifice with the collected substances. Method of using the hygiene device are also provided.

A surgical instrument and method of removing a portion of a tissue mass includes a shaft, a cutting member, and an aspiration vent. The shaft has a shaft lumen, a shaft window, and a shaft edge. The cutting member is disposed within the shaft lumen and is configured to cyclically move from a first position to a second position relative to the shaft. The cutting member includes a cutting window opening, a cutting edge, and a suction lumen to cut the tissue portion with the cutting member in the first position. The aspiration vent extends through at least one of the shaft or the cutting member for fluid communication with the suction lumen to suction an airflow for urging the tissue portion away from the cutting edge and along the suction lumen.
