Endoscopic vessel harvester with gyrosensor on handle for rotating camera view

An endoscopic vessel harvesting tool uses an optics system to present of a video image to a user. As the tool is manipulated around all sides of the vessel to dissect and cut surrounding tissue and side branches, the orientation of the captured image rotates. A motion tracker (e.g., gyrosensor) in the tool detects the rotation. By detecting a rotational angular velocity of the harvester handle during the harvesting procedure, the camera view orientation is compensated before display to the user. When the handle is rotated, the detected rotation is used to provide an opposite (canceling) rotation of the camera view so that a steady orientation is presented on the display. Thus, a vertically upward direction (or any other desired reference direction) remains substantially fixed in the displayed video images.

Method for obstructive sleep apnea syndrome remedy

FIELD: medicine. SUBSTANCE: pre compression-distraction osteogenesis is performed by cutting through the transitional fold of the oral mucosa from the retromolar area to the second premolar of the lower jaw. Then the lower jaw branch and/or body is skeletonized. The outer cortical layer is cut, and the outer and inner cortical plates on the front and rear edge of the lower jaw branch are cut. An intraoral extramedullary compression-distraction device is installed which is fixed with mini-screws passing through the two cortical layers, followed by inner cortical bone fracturing, bone fragments compression and lower jaw distraction. After the retention period, bilateral sagittal-plane osteotomy of the mandible is performed with removal of compression-distraction devices and upper jaw osteotomy with its subsequent extension forward with further upper and lower jaw fixation in orthognathic position. Then, by lower jaw trapezoidal osteotomy with chin forward projection, augmentation genioplasty is performed. EFFECT: method allows to increase the missing bone tissue amount in the lower jaw body and branch areas, as well as to reduce process trauma due to gradual stretching of the inferior alveolar nerve in order to create conditions for further orthognathic surgery. 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 617 120 C1 (51) МПК A61B 17/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2016113154, 07.04.2016 (24) Дата начала отсчета срока действия патента: 07.04.2016 Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 07.04.2016 (45) Опубликовано: 21.04.2017 Бюл. № 12 (56) Список документов, цитированных в отчете о поиске: RU 2289343 C1, 20.12.2006.

Method of direct dental implantation

FIELD: medicine. SUBSTANCE: invention relates to medicine, namely to maxillofacial surgery, and is intended for use in the treatment of patients with partial tooth loss in the anterior section using dental implants. Removal of the tooth and pathological tissues, the treatment of the hole with an antibiotic, the formation of the bone bed in the interior of the alveolar process, the marking of the position of the implant and its installation, the filling of the free space between the walls of the alveolus and the implant with biomaterial stimulating osteogenesis. After processing the well with the antibiotic, 0.9% solution of sodium chloride. Immediate dental implantation is carried out simultaneously with soft tissue plasty. In this case, the preparation axis is displaced by 20-22° from the axis of the alveolus of the removed tooth. Install the implant and the plug, in the area of the marginal gingiva from the vestibular side. Carry out an intra-groove incision in such a way that a “pocket” is formed inside, bounded on one side by the periosteum, with the other mucosa. From the donor zone on the upper jaw - the hard palate or the upper jawbone area - the combined free gingival graft is sampled in such a way that it consists only half of the connective tissue and the other includes the epithelium. With the help of ceramic boron, remove the surface layer of the epithelium by 2 mm from the edge, obtaining an autotransplant with three zones: an epithelial strip in 2 mm, a diepithelial and connective tissue zone. Place the transplant in the formed “pocket” of the recipient bed and fix the nodular seam to the mucosa from the vestibular side so that the graft is immersed to the epithelial stripe. Space between the vestibular wall and the implant is filled with osteoplastic material based on hydroxyapatite. Plug is replaced with a gingiva former. On mucous membrane impose a U-shaped seam. EFFECT: method, through the use of a one-step method of implantation, reducing the ...
