A sheath assembly is adapted for an ultrasonic probe and includes a plug portion and a sheath portion connected to each other. One end of the plug portion of the sheath assembly is used for detachably and fixedly connecting with a connecting butt joint portion of the ultrasonic probe, so that the plug portion and the connecting butt joint portion are detachable after the ultrasonic probe is used.

An endoscope eyepiece grasping mechanism includes a base part engaging a tab member via a connected engagement member. An annular part has an outer engagement surface and an inner camming surface disposed coaxially with the base part and axially moveable relative to the base part. The engagement surface is moveable with the camming surface to move the tab member radially outwardly, with a movement of the annular part relative to the base part in a first axial direction, toward a receiving position, and to move the tab member radially inwardly, with movement of the annular part relative to the base part in a second axial direction, toward a grasping position. A biasing device acts to bias the annular part toward the grasping position. An endoscope eyepiece is engaged by the tab member upon the annular part moving from the receiving position to the grasping position.

An apparatus, system and process for identifying one or more different tissue types are described. The method may include applying a configuration to one or more programmable light sources of an imaging system, where the configuration is obtained from a machine learning model trained to distinguish between the one or more different tissue types captured in image data. The method may also include illuminating a scene with the configured one or more programmable light sources, and capturing image data that includes one or more types of tissue depicted in the image data. Furthermore, the method may include analyzing color information in the captured image data with the machine learning model to identify at least one of the one or more different tissue types in the image data, and rendering a visualization of the scene from the captured image data that visually differentiates tissue types in the visualization.

A visualization device for a robotic surgery apparatus includes a housing configured to be removably attached to a mounting interface of the apparatus and be positioned adjacent an insertion device of the apparatus. The housing includes first and second openings positioned on an exterior of the housing. The housing includes a substantially flexible camera tube with a first end attached to the housing and a second end including at least one camera. The second end is inserted through the first opening in the housing, pass through interior of the housing, and exit the housing through the second opening in the housing. The second end extends away from the housing toward a region of interest outside the housing or retract away from the region of interest and back toward the housing. The camera tube forms a loop around a portion of the housing.

A device for attaching an optical element, such as an otoscope, to a smart phone for diagnosing and/or identifying problems of an outer ear, a middle ear, and/or an ear canal of a patient. The device may comprise a main body. The main body may comprise an aperture and a first engagement member configured to engage with a second engagement structure that belongs to the optical element. A first surface may be connected to the main body and configured may be to contact a first smart phone surface. A piston may be provided that may comprises a second surface that may be parallel to the first surface and may be configured to contact a second smart phone surface. A threaded knob may be provided and may be connected to the piston through the aperture.

A retractable syringe device includes: a handle including a hollow body for receiving a syringe through an opening of the handle, the hollow body including a syringe actuator that moves the syringe between a distal position and a proximal position; and an instrument distally extending from the handle, the instrument including a channel extending through the instrument, the channel configured to receive a needle coupled to the syringe. When the syringe is in the distal position, a distal end of the needle distally extends from the instrument, and when the syringe is in the proximal position, the distal end of the needle is retracted into the channel. The handle of the device can include a fixed or removable structure for removably coupling to a proximal end of a shaft of an endoscope.

There is provided an endoscope that allows the distal end portion of a wire and a treatment tool-elevator to be easily connected to each other. An engaging portion (100) is provided at the distal end portion of a wire (60). An elevator (30) is provided with a contact portion (101) that applies a rotational moving force acting in a fallen direction to the elevator (30) in a case where the engaging portion (100) is in contact with the contact portion. The elevator (30) is provided with a housing portion (102) in which an opening (104) is formed. A wall portion (81) is provided at a position that faces the movement trajectory of the engaging portion (100) in a case where the elevator (30) is moved between an elevated position and a fallen position in a state where the engaging portion (100) is in contact with the contact portion (101). In a state where the engaging portion (100) is in contact with the contact portion (101), the wall portion (81) regulates the movement of the engaging portion (100) in a direction where the engaging portion (100) enters the opening (104) in a case where the elevator (30) is present between the elevated position and the fallen position and allows the movement of the engaging portion (100) in the direction where the engaging portion (100) enters the opening (104) in a case where the elevator (30) is present between the fallen position and an attachment/detachment position.

A medical system includes an insertion device including a delivery shaft with an internal lumen, a coupling tube coupled to the delivery shaft and configured to receive a medical device, and a liner tube inserted through the internal lumen of the delivery shaft.

A surgical access device includes a housing, a tubular member extending from the housing, a valve disposed on the housing, and a tip member at a distal end of the tubular member. The housing includes a seal and the tubular member includes a plurality of lumens extending therethrough. The valve is fluidly coupled with a first lumen of the plurality of lumens and the tip member includes a first port that is aligned and fluidly coupled with the first lumen of the plurality of lumens. The first port is configured to direct a fluid towards a predetermined location.
