Abstract: Catheter placement in the brain has traditionally been done largely blindly, utilizing surface landmarks (such as entry at the mid-pupillary line anterior to the coronal suture, with catheter target aiming at the medial canthus and tragus for the ventriculostomy procedure). This invention relates to methods and devices for placement of catheter(s), more particularly to guided modality for catheter placement, and more particularly to guided modality placement of intracranial catheters using intra-luminal ultrasound, employing a drill, surgical navigation, non-real-time-navigated external guide, or any combination thereof.

Abstract: A device for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions using intra articular localization has a guide, a locating arm, a set of attachment assemblies and a tubular sleeve. The device comprises a device body and an attachment assembly mounted on the device body. The attachment assembly includes a main body and at least one closure body. The main body has an elongated recess therein. The elongated recess is configured for receiving an elongated member therein along an entire length thereof. The at least one closure body is rotatably mounted on the main body. The elongated member may be positioned within the elongated recess via lateral movement when the at least one closure body is in a first rotational position relative to the main body. The elongated member may be retained within the elongated recess when the at least one closure body is moved away from the first rotational position toward a second rotational position relative to the main body.

Abstract: 一种椎骨钉道血管成像方法、系统及椎骨钉道创建引导装置，该成像方法包括以下步骤：1)采集多帧重复频率的回波时间序列数据；2)分割成相邻之间有一定重叠率的多个深度窗；3)将时序信号转变成声谱图；4)提取最大多普勒频移曲线，计算该深度窗的加强功率谱指数；5)输出加强功率谱指数曲线；6)获取一周内各个角度位置的加强功率谱指数曲线；7)综合所有的加强功率谱指数曲线，得到二维血流图像，提取得到椎骨钉道外周的血管位置信息。采用多普勒功率谱并提取相关指数，通过滑动深度窗获取加强功谱勒指数曲线，反映血流信号强度随深度的变化，能检测到被骨壁衰减后的血流信号，可获得骨壁后血流的位置信息。

Abstract: A bone fusion assembly includes a bone plate having a plurality of through openings extending therethrough. The through openings include at least one fusion screw opening sized to allow a screw guide to be at least partially inserted therein and a plurality of fixation screw through openings. The screw guide includes a body having a proximal end, a distal end, and a through-passage extending between the proximal end and the distal end. A K-wire a sized to extend through the through-passage in the body of the screw guide.

Abstract: A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.

Abstract: In accordance with one or more embodiments herein, a metatarsal implant (300) for repairing damage in a metatarsophalangeal joint of a patient is provided. The metatarsal implant (300) is adapted to be attached to an implant receiving surface (420) which has been created on a metatarsal head (410) of the patient by sawing off sections of the metatarsal head (410), and an articulating surface (310) of the metatarsal implant (300) is designed to correspond to the curvature of a simulated healthy articulating surface of the undamaged metatarsal head (410) at a site of diseased cartilage and/ or bone. A bone contacting surface (330) of the metatarsal implant (300) is designed to correspond to the implant receiving surface (420), and the contour curvature of the articulating surface (310) is generated based on a determined surface curvature of the cartilage and/or the bone in a predetermined area at the site of diseased cartilage and/or bone, to mimic the original, undamaged, articulating surface of the metatarsal head (410).

Abstract: A personalized implant (100) for bone replacement comprises an implant body (101) as a reconstruction of a bone portion. The implant body comprises a closed cavity (106) and a solid impervious layer (105) of material defining an outside surface of the implant body exposed to an exterior of the implant. The solid impervious layer fully encloses the closed cavity inside the implant body. The closed hollow interior can comprise an open support structure to reinforce the solid outside layer.

Abstract: The invention relates to a device for intramedullary nailing of the tibia which comprises the frame of a framework which consists of vertical supports (2) and longitudinal (3, 4) and transverse horizontal supports (5, 5', 5", 6, 6') and a guide (21): which is slidably coupled to the longitudinal horizontal support (4) of the device. The guide (21) comprises a first finder (11) for adjusting the position of the traction needle (20) in the lateral direction, and a second finder (13) for adjusting the position of the traction needle (20) in the vertical direction and for passing the traction needle (20) through the tibia in the transverse direction of the tibia, and attachment arms (22, 24) attached to the frame, to which the ends of the traction needle (20) outside the tibia are attached.
