The present invention describes an improved surgical mouth gag for the exposure of the palatal and oropharyngeal region of a patient comprising a frame (2) adapted to be arranged in use around the mouth of the patient and a tongue depressor system (21, 30) insertable in the oral cavity of the patient and movable with respect to the frame (2), the tongue depressor blade (21, 30) comprising two elements articulated to each other, able to mobilise fully in a graduated way the entire tongue base both in the caudal and posterior-anterior direction. The metal arch (2) supports and anchors the aforesaid tongue depressor system, by resting on the upper premolar and molar teeth (respecting the incisors) and acts as an anterior window adapted to guarantee both optimal exposure of the palatal structures and of the isthmus of the fauces and to facilitate palatal and oropharyngeal surgery in general and that of obstructive sleep disorders in particular.

The present invention provides laryngeal mask airway for sedative endoscopy, including: a laryngeal mask/endoscope guide unit which is positioned in a larynx region inlet through a patient's oral cavity and guides a supply of air to a respiratory tract and insertion of an endoscope into an esophagus; an airway unit which is connected to the laryngeal mask/endoscope guide unit to supply air to the patient's respiratory tract and to allow the patient's breathing state to be visually checked; a mouthpiece unit which is installed outside the airway unit and fixed between the patient's teeth to protect a tube of the airway and an endoscopic probe inserted into the oral cavity; and an indication end which is positioned at a portion of the mouthpiece positioned outside the oral cavity and moves in accordance with the patient's breathing state to allow spontaneous breathing to be checked, such that the patient's safe airway may be ensured, the insertion of the endoscopic probe and the procedure may be smoothly performed, the patient's spontaneous breathing is easily checked even in a dark space, and as a result, the endoscopy may be safely performed.

An obesity treatment apparatus comprises at least one operable stretching device implantable in an obese patient and adapted to stretch a portion of the patient's stomach wall, and an operation device for operating the stretching device when implanted to stretch the stomach wall portion such that satiety is created.

A vaginal speculum that includes a fixed blade and a movable blade. The movable blade designed to be extended or retracted as required in order to adjust to the length of the vaginal canal of the patient undergoing surgery. A vaginal speculum is further designed with a blade angle mechanism and a blade pivoting mechanism that allows and controls the angle and rotation of the blades in relation to its base. Vacuum connection and a light can also be provided.

A female urethral catheterization assist device is provided. The female urethral catheterization assist device includes a first lateral arm pivotally secured to a second lateral arm. Each lateral arm includes a platform placed opposite a handle. A paddle extends upward from each platform on an interior lateral side of each platform. The paddles are designed to engage the labia minora and labia majora of a patient and to assist with urethral catheterization.

A visualized medical system with a cavity expanding device includes a cavity expanding mechanism and an observation mechanism. The cavity expanding mechanism includes an expanding end arranged at a front end of the operating mechanism and configured to expand a cavity at the front end of the observation mechanism to expand a field of view of the observation mechanism. The observation mechanism includes a lighting module, a lens module, a signal processing module, and a housing. An image and a video observed in the lens module in a light field of the lighting module are processed by the signal processing module, and then outputted to a display system by a circuit system for displaying. The visualized medical system with a cavity expanding device can introduce a surgical instrument into a body from a sheath to perform various surgical operations such as biopsy sampling, electrocution, electrocoagulation, and ablation during observation.

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.
