A medical device operation training apparatus, used in performing training for operation of a medical device, includes: an affected-area simulated organ holding unit configured to hold a sheet-like affected-area simulated organ able to be incised or excised at least in part; and a path simulated organ holding unit configured to hold a path simulated organ for guiding the medical device to the affected-area simulated organ. With this apparatus, trainees can train for various manipulations with simple preparatory operations.

The present invention discloses an endoscope apparatus and an endoscopic method. The endoscope apparatus includes a release source, a tether connected to the release source, an elastic clamp member and a capsule endoscope. The elastic clamp member includes an elastic clamp cavity being interconnected to an air outlet of the release source through the tether. In a clamped state, at least a portion of the capsule endoscope is within the elastic clamp cavity, wherein the elastic clamp member has a tendency to recover from deformation to apply a clamping force to the capsule endoscope. In a released state, the elastic clamp member is expanded by the air pressure from the tether, and the capsule endoscope is released from the elastic clamp cavity.

An ultrasound device (10) includes a probe (12) including a tube (14) sized for insertion into a patient and an ultrasound transducer (18) disposed at a distal end (16) of the tube. A camera (20) is mounted at the distal end of the tube in a fixed spatial relationship to the ultrasound transducer. At least one electronic processor (28) is programmed to: control the ultrasound transducer and the camera to acquire ultrasound images (19) and camera images (21) respectively while the ultrasound transducer is disposed in vivo inside the patient; and construct a keyframe (36) representative of an in vivo position of the ultrasound transducer including at least ultrasound image features (38) extracted from at least one of the ultrasound images acquired at the in vivo position of the ultrasound transducer and camera image features (40) extracted from one of the camera images acquired at the in vivo position of the ultrasound transducer.

A multifunctional catheter includes a catheter main body (1) and a distal tube (2) that are in a multi-channel structure. The distal tube (2) includes a soft end (21) at a proximal end and a functional end (22) at a distal end; a working channel (3) and a lens channel (6) are provided in the catheter main body (1) and the soft end (21), and the functional end (22) is also provided with a through hole communicating with the lens channel (6); the lens channel (6) is of a circular tubular-cavity structure extending along the catheter main body (1) and the soft end (21); and a plurality of accommodating slots (61) are provided on an inner wall of the lens channel (6) to accommodate a photosensitive chip in a lens assembly by the plurality of accommodating slots (61).

The disclosure provides a diagnosis and treatment integrated soft medical robot for gastrointestinal endoscopy, including a robot body, a camera, illumination devices, a flexible dielectric elastomer actuator, air cylinders, linear motors, a controller and external hoses. Wherein the robot body is a multichannel hose, and includes a central channel and circumferential channels, the central channel is configured to accommodate conducting wires and signal wires, the circumferential channels include at least three microfluid channels. The front end of each microfluid channels is a sealed end, a rear end of each of the microfluid channels is an open end. The open end of each microfluid channels communicates with an end opening of a flow channel of one air cylinder. The linear motors control fluid pressures in the microfluid channels by driving piston rods of the air cylinders so that the robot body steers through being driven by fluid. The camera performs real-time image acquisition. The controller controls the flexible dielectric elastomer actuator to capture a target. The disclosure realizes the real-time image acquisition on a digestive tract, particularly a lesion, and can integrally and fast complete diagnosis and treatment.

TNE provides the opportunity to make the care of children with EoE and other gastrointestinal or aerodigestive conditions safer, more efficient, and less costly while simultaneously advancing our understanding of the pathophysiology and natural course of this condition. A pediatric endoscope was developed to facilitate TNE in children with EoE. The pediatric endoscope (combined gastroscope, bronchoscope, laryngoscope) includes a 3-4 mm flexible, fiber optic endoscope that allows HD TV viewing with the head of a pediatric bronchoscope that allows four way tip deflection, a scope stiffening apparatus to minimize the endoscopes flexibility when needed, a foot and hand activation to allow air/water insufflation and image/video capture, a light source, 2 mm biopsy channel.

Novel airway devices and methods address complications of ventilating a patient with a mask; placing an endotracheal tube in an awake patient; and need for a bite block during flexible bronchoscopy and gastroscopy. The airway device features notches for engaging maxillary and mandibular teeth in a manner protracting the patient's mandible relative to the maxilla to open up the airway. This way, an open airway is easily maintained simply by holding the jaw closed against the device with the same hand used to operate a bag ventilator. A longitudinal channel in the device features a downwardly curved end wall for improved guidance of the endoscope into position. The channel is open sided at the top or bottom to allow rolling of the airway device off the endoscope into an offset position serving as a protective bite block and allowing feeding of the endotracheal tube along the endoscope.

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.
