In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

An endoscope includes a handle including a handle housing, an irrigation inlet port adapted to receive irrigation fluid, and an irrigation channel; and an insertion cord extending distally from the handle. The insertion cord includes an insertion tube; a bending section extending from the insertion tube; a distal tip extending from the bending section and including a tip housing; a camera at least partially enclosed in the tip housing; interstitial space within the insertion tube in fluid communication with the irrigation channel; and at least one interstitial flow opening in fluid communication with the interstitial space and adapted to discharge the irrigation fluid.

Foreign matters of variable size in the interior of one's auditory canal are removed infallibly.

An image capturing tube 220 adapted to be inserted into one's auditory canal to output an image of an interior of the auditory canal, a suction tube 230 provided along the image capturing tube 220 to suck a foreign matter in the interior of the auditory canal, and a main body unit 200 provided with the image capturing tube 220 and the suction tube 230 are included. The image capturing tube 220 includes a camera 240 adapted to capture the image of the interior of the auditory canal, and to a tip end of the suction tube 230, a dust collecting tube 232 is attached.

A resectoscope for endoscopic surgery, having a tubular shaft which includes an elongated sheath tube, and an irrigation tube arranged in the sheath tube for supplying irrigation fluid, as well as a rod-shaped lens and an electrode instrument, characterized in that the lens and the electrode instrument are arranged between the outer wall of the irrigation tube and the inner wall of the sheath tube. In addition, an electrosurgical system including the resectoscope and an irrigation fluid supply device.

An eardrum incision device includes a main body, a replaceable inserting portion and a display device. The replaceable inserting portion is detachably connected to the main body. The replaceable inserting portion has an insertion end located on a side far away from the main body and adapted to be inserted into an ear canal of a user. The replaceable inserting portion includes an image-capturing device, a mounting hole and a replaceable incision component. The image-capturing device is disposed at the insertion end. The mounting hole extends in a direction from the insertion end toward the main body. The replaceable incision component is removably disposed in the mounting hole and adapted to pierce out of the mounting hole in a direction toward the insertion end, so as to incise the eardrum of the user. The display device is disposed on the main body and electrically connected to the image-capturing device.

A laparoscopic flexible suction/irrigation device of the present invention encases a inner rigid cannula with an outer flexible cannula. Upon translating the distal end of outer flexible cannula beyond the distal end of the inner rigid cannula, the outer flexible cannula returns to a preexisting curvilinear shape. This curved extension can thereafter be positioned via a proximal handle to concavities within the surgical site for precise and effective fluid retraction.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

An endoscope sheath comprising: (a) a proximal end, (b) a distal end having a distal end region, (c) a surface extending between and connecting the proximal end and the distal end, (d) a plurality of positioning devices located along the surface; and (e) one or more drip retention features; wherein the sheath is configured to: (i) receive all or a portion of an endoscope and (ii) provide a conduit for communicating fluid between the proximal end of the endoscope sheath and the distal end of the endoscope sheath when the endoscope is inserted inside the sheath; and wherein the plurality of positioning devices are located in a distal end region at the distal end of the endoscope sheath so that the endoscope is secured within the endoscope sheath; and wherein the one or more drip retention features are configured to produce a region bounded by the endoscope sheath and the endoscope to retain a volume of liquid by capillary action.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.
