Device and method of assisted anatomical localization The invention relates to a method and a device (2) of anatomical localization.The method comprises: obtaining an image (IM1) of a subject (UR2); detecting at least two first anatomical points (PT1) associated with the subject's skull; determining a first value (V1) representing a reference distance (D1) separating the first two anatomical points; detecting two second anatomical points (PT2) associated with the subject's shoulders; locating a sternal midline equidistant from the second anatomical points (PT2), the sternal midline intersecting at a point of intersection a segment defined by the second anatomical points (PT2); and determining coordinates (C1) of at least one target anatomical point (PT3) by calculating second distances (D2x, D2y) of said at least one target anatomical point with respect to the point of intersection, the second distances being determined from the first value (V1). Figure for the abstract: Fig. 1.

This utility model discloses a duckbill-shaped intraoperative suction device, comprising a suction head, a suction tube, and a negative pressure suction device connected in sequence. The suction head is a flat tubular structure with a thickness smaller than its length and width. One end of the suction head along its length is directly or indirectly connected to and communicates with the suction tube, while the other end of the suction head along its length is a closed end or has an end through hole. Multiple through suction holes are also distributed on the suction head. This duckbill-shaped intraoperative suction device replaces the traditional cylindrical suction head with a duckbill-shaped, flat tubular structure. The suction head has a thin and flat shape, making it better suited for patients undergoing reoperation, especially children. It can be inserted behind the sternum in a very small space and increases the area of ​​protection behind the sternum, helping to avoid damage to the heart and major blood vessels behind the sternum during a second thoracotomy.

The utility model relates to puncture tool technical field, concretely for bone marrow puncture needle, including needle tube, needle tube is used for puncture extraction bone marrow, the lower extreme of needle tube is installed with needle tube seat, the inside of needle tube is provided with core needle, the lower extreme of core needle is installed with core needle seat, the end of adjusting sleeve is provided with inclined annular surface to adapt the use condition of 45 degree -60 degree inclined needle insertion of sternum bone marrow puncture, core needle seat is equipped with the lock catch, the limiting block is set up on needle tube seat, when the tip of core needle is pressed, the lock catch is hooked needle tube seat through the cooperation with limiting block, prevents core needle from retreating, the convex point is equipped on core needle seat for preventing core needle seat from rotating freely and taking out. In the bone marrow puncture needle, the inclined annular surface of adjusting sleeve end head, perfect adaptation 45 degree -60 degree inclined needle insertion of sternum bone marrow puncture use condition, solve the problem that the small observation field of operator can be observed when the traditional puncture needle punctures, and the discomfort of patient skin, make puncture operation more accurate, convenient.
