摘要： A surgical retractor assembly for providing a generally constant retracting force at a fixation site on a patient despite possible movements of the fixation site during application of the retracting force. The retractor assembly comprises a support structure engaging element for providing communication between the surgical retractor assembly and a support structure; a retractor guide for receiving a first end of a retracting member, the retractor guide being coupled to the support structure engaging element, wherein the retractor guide is displaceable relative to the support structure engaging element; and a biasing structure that provides the retracting force.

摘要： A needle biopsy system (10) includes a biopsy needle (210), and a needle support assembly (200). The needle support assembly (200) holds the biopsy needle (210) and manipulates the biopsy needle (210) in response to received control signals. A needle simulator (250) having an input device (252) generates the control signals in response to manipulation of the input device (252) by an operator. The operator, in turn, receives feedback from the needle simulator (250) in accordance with forces experienced by the biopsy needle (210). In a preferred embodiment, the feedback received by the operator includes tactile sensations experienced by the operator as the operator manipulates the input device (252). The tactile sensations mimic those the operator would have received had the operator directly manipulated the biopsy needle (210). Optionally, a curved needle guide (280) is employed to restrict the biopsy needle's progression longitudinally therethrough.
摘要翻译：针活检系统（10）包括活检针（210）和针支撑组件（200）。针支撑组件（200）保持活检针（210）并响应于接收的控制信号操纵活检针（210）。具有输入装置（252）的针模拟器（250）响应于操作者对输入装置（252）的操纵而产生控制信号。操作者又根据活检针（210）所经受的力从针模具（250）接收反馈。在优选实施例中，由操作者接收的反馈包括当操作者操纵输入装置（252）时由操作者经历的触感。如果操作人员直接操纵活检针（210），则触觉感觉模拟操作者将接收的触感。任选地，使用弯曲的针引导件（280）来纵向地限制活检针的进展。

摘要： An imaging apparatus (18) includes a frameless stereotactic arm apparatus (30) including a first base portion (42) mounted in a fixed relationship to the imaging device. A second free end (40) of the arm assembly is adapted to move into varied positions near a specimen disposed on the imaging apparatus. At least one pivot joint (44, 48, 52, 56, 60) is provided between the first base portion and the free end of the arm for permitting selective relevant movement between the arm members. Electro-mechanical and electro-magnetic brake devices are provided at respective joints to selectively lock the free end of the arm assembly to the base portion. The brakes are responsive to a brake command signal (210) generated by the imaging device. A low pass filter (240) conditions the brake command signal to substantially eliminate high frequency electromagnetic switching noise in the stereotactic arm. So that the arm is movable in emergency situations, the brakes are adapted to rebase in response to application of a force in excess of a predetermined breakaway threshold force.
摘要翻译：成像装置（18）包括无架立体定向臂装置（30），该装置包括与成像装置成固定关系的第一基部（42）。臂组件的第二自由端（40）适于移动到设置在成像装置上的样本附近的不同位置。至少一个枢转接头（44,48,52,56,60）设置在第一基座部分和臂的自由端之间，以允许臂部件之间的选择性相关的运动。机电和电磁制动装置设置在各个接头处以选择性地将臂组件的自由端锁定到基部。制动器响应于由成像装置产生的制动指令信号（210）。低通滤波器（240）调节制动指令信号，以基本上消除立体定向臂中的高频电磁开关噪声。因此，臂在紧急情况下是可移动的，所以制动器响应于施加超过预定的分离阈值力的力而被适应。
