Abstract: A method and an apparatus for sharing an App, an electronic device and a storage medium are provided. The method includes in response to detecting a preset trigger operation for an App, displaying associated regions for associated devices; in response to a selecting operation for any of the associated regions, determining an associated device corresponding to the any of the associated regions as a target device; and sending interface display data of the App to the target device, so that the target device displays a program interface of the App based on the received interface display data.

Abstract: A minimally invasive ultrasonic osteotome head and a minimally invasive ultrasonic powered system for bone; the minimally invasive ultrasonic osteotome head comprises an osteotome rod (11, 21, 31, 41, 51, 61) and a head end (12, 22, 32, 42, 52, 62), the head end (12, 22, 32, 42, 52, 62) being located at a front end of the osteotome rod(11, 21, 31, 41, 51, 61), and the head end (12, 22, 32, 42, 52, 62) being bent laterally at a certain angle, wherein knurled teeth or skewed teeth are provided on the bent portion. By means of bending the head end (12, 22, 32, 42, 52, 62), bone tissue around the transforaminal endoscope may be removed. Therefore, a surgeon may, as much as possible, have more operation space under the limited endoscope channel, thereby increasing bone removal efficiency.

Abstract: A holder for intervertebral foramen endoscope fusion includes an inner rod, an anti-torsion sleeve and an outer sleeve which are sleeved from inside to outside and are movable relatively along an axial direction. The inner rod is configured for pushing the expanding part inside a fusion cage. A head end of the anti-torsion sleeve is provided with an external thread section, the external thread section is configured for matching and connecting with the screw plug mounting hole of a holding body of the fusion cage, and the tail end of the anti-torsion sleeve is provided with a matching structure for matching with the bone grafting funnel. A head end of the outer sleeve is matched with the holding body of the fusion cage to restrict the rotation of the fusion cage along an axis of the fusion cage. A surgical instrument assembly is also provided.

Abstract: A minimally invasive ultrasonic cutter head and a minimally invasive ultrasonic powered system for bone; the minimally invasive ultrasonic cutter head comprises an cutter rod (11, 21, 31, 41, 51, 61) and a head end (12, 22, 32, 42, 52, 62), the head end (12, 22, 32, 42, 52, 62) being located at a front end of the cutter rod (11, 21, 31, 41, 51, 61), and the head end (12, 22, 32, 42, 52, 62) being bent laterally at a certain angle, wherein knurled teeth or skewed teeth are provided on the bent portion. By means of bending the head end (12, 22, 32, 42, 52, 62), bone tissue around the intervertebral foramen may be removed. Therefore, a surgeon may, as much as possible, have more operation space under the limited foramen channel, thereby increasing bone removal efficiency.
