A method for acquiring at least one two-dimensional image of a part of arches of a patient includes steps carried out by the patient or other person who is not a dental health professional, for example, including placing a dental separator in the mouth of the patient in order to separate the lips of the patient and improve the visibility of the teeth during the acquisition of said at least one two-dimensional image, and acquiring, in a mouth closed position and with a personal image acquisition apparatus, said at least one two-dimensional image.

An intraoral imaging apparatus, a medical apparatus, and a program capable of providing auxiliary data for determination regarding diseases having differences in intraoral findings are provided. The intraoral imaging apparatus includes: an imaging device that acquires an intraoral image; a light source that emits light to a subject of the imaging device; a storage apparatus that stores an algorithm for performing determination of a specific disease; and an arithmetic apparatus, in which the arithmetic apparatus executes: a determination process of determining a possibility of the predetermined disease based on the image and the algorithm; and an output process of outputting a result of the determination process.

An apparatus for treating obesity in a human or animal mammal patient. The apparatus comprising a first volume filling device segment and a second volume filling device segment. The first and second volume filling device segments are adapted to be assembled into an implantable volume filling device of a controlled size. Each one of the first and second volume filling device segment comprises at least one interconnecting structure. The interconnecting structure of the second volume filling device segment is adapted to be formed fitted, such that the first and second volume filling device segment can be assembled into the volume filling device. The assembled volume filling device is adapted to be at least substantially invaginated by a stomach wall portion of a patient, with the outer surface of the device resting against the stomach wall, such that the volume of the food cavity is reduced in size.

Medical packaging is provided for enclosing a single-use medical device with multiple frangible operating lines and corresponding frangible connections to define a removable first end which reveals at the time of use an operative part forming the key part that is to come into contact with the patient. The remaining part of the device including the controlling part is retained in the rest of the packaging but can be used to control the device without hindrance. Each of the multiple frangible operating lines indicating on the packaging the difference between the key part that forms the operating part of the device for one of a plurality of predefined medical procedures wherein the identification of the frangible operating lines immediately educates and instructs the user in the correct usage in a sterile and clean manner.

A camera system for use with retractors. The system includes a camera assembly configured for mounting on the proximal end of a retractor system, such as the proximal end of a blade such that the entirety of the camera assembly is disposed at the proximal end of the retractor system may be disposed such that the distal-most optical element overhangs the working channel established by the retractor, and includes a reflector and a rotatable mount for the reflector, camera assembly viewing axis may be altered without changing the position of the entire camera assembly.

This disclosure relates to the field of luminal surgery. Specifically, the present disclosure relates to medical devices that expand within a body lumen for accessing a target tissue. In an aspect, an expandable device for a body lumen may include a filament comprising a proximal end, a distal end, and a length. The device may include a plurality of segments. Each segment may comprise a middle portion comprising a longitudinal axis extending axially therethrough, a projection portion extending from an end of the middle portion along the longitudinal axis, and a receptive portion extending from an opposing end of the middle portion away from the longitudinal axis, the receptive portion configured to receive the projection portion of an adjacent one of the plurality of segments. An aperture may be disposed through the projection portion, the middle portion, and the receptive portion.

A surgical retractor includes a mounting base, a first rod member, a connecting member, a compression spring, a second rod member, an expansion member, an extension spring and a position member. One end of the first rod member is assembled on the mounting base, and the other end of the first rod member includes a blocking part; the connecting member is assembled on the first rod member and includes a shoulder and a first connecting part; the compression spring is arranged on the connecting member and abuts against the shoulder and the blocking part; the second rod member is slidably arranged on the first rod member; the expansion member is arranged at the end of the second rod member and includes a second connecting part; an extension spring connects the first connecting part and the second connecting part; a position member selectively abuts against the first rod member.
