    摘要： A tissue biopsy system includes a biopsy device, a display, and a processing unit in communication with the biopsy device and the display. The biopsy device includes a handle body, a transducer, and a needle. The transducer is disposed within the handle body. The needle is configured to be deployed from the handle body and into tissue. The display is configured to display an ultrasound image of the tissue based on data collected by the transducer. The processing unit is configured to identify an area of interest, located in the tissue, based on the ultrasound image and visually indicate the area of interest on the display.

    摘要： A sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.

    摘要： Provided in accordance with the present disclosure are systems for identifying a position of target tissue relative to surgical tools using a structured light detector. An exemplary system includes antennas configured to interact with a marker placed proximate target tissue inside a patient's body, a structured light pattern source, a structured light detector, a display device, and a computing device configured to receive data from the antennas indicating interacting with the marker, determine a distance between the antennas and the marker, cause the structured light pattern source to project and detect a pattern onto the antennas. The instructions may further cause the computing device to determine, a pose of the antennas, determine, based on the determined distance between the antennas and the marker, and the determined pose of the antennas, a position of the marker relative to the antennas, and display the position of the marker relative to the antennas.

    摘要： A desiccation device for operation on a target tissue includes a handle, a shaft extending distally from the handle, and a head. The shaft defines a lumen therethrough, and the head has a loop configuration supported on a distal end of the shaft. The head is hollow and defines a lumen therethrough. The lumen of the head is in fluid communication with the lumen of the shaft. At least a portion of the head is electrically connected to a source of electrosurgical energy. A fluid is circulatable through the lumens of the shaft and the head.

    摘要： An electrosurgical instrument includes a housing, an elongated shaft, and an end-effector assembly. The proximal end of the shaft is operably associated with the housing. The end-effector assembly is operably coupled to the distal end of the shaft and includes first and second jaw members. Each of the first and second jaw members includes a sealing plate and a bipolar electrode. Either one or both of the first and second jaw members is movable from a position in spaced relation relative to the other jaw member to at least one subsequent position wherein the sealing plates cooperate to grasp tissue therebetween. The electrosurgical instrument includes a semiconductor switch operably coupled to at least one of the sealing plates and at least one of the bipolar electrodes. The semiconductor switch is configured to enable user selection between energizing the at least one sealing plate or the at least one bipolar electrode.

    摘要： An electrosurgical suction coagulator is disclosed having improved thermal insulation between the active electrode and adjacent tissue. In embodiments, passive insulation is used to control the transfer of thermal energy from an electrosurgical electrode into surrounding tissue. Braided, closed-sell foam material, and open cell foam materials may be used to thermally insulate the outer surface of a suction coagulator shaft from an inner electrode. In embodiments, a suction coagulator shaft includes an external covering formed from open-cell foam material, which may be saturated with a coolant, such as water or saline, to increase the thermal mass of the shaft. In other embodiments, active cooling delivers coolant to the operative site. In yet other embodiments, a suction coagulator shaft includes a cooling jacket through which coolant is passed to actively cool the instrument. The improved electrosurgical suction coagulator disclosed herein may have a reduced operating surface temperatures which may result in reduced risk of undesirable effects to adjacent tissue, and may result in reduced operative times and improved patient outcomes.

    摘要翻译： 公开了一种电外科吸入式凝结器，其具有改善的活性电极和相邻组织之间的热绝缘。 在实施例中，被动绝缘用于控制从电外科电极到周围组织的热能传递。 可以使用编织的封闭泡沫材料和开孔泡沫材料来将吸入式凝结器轴的外表面与内部电极进行热绝缘。 在实施例中，抽吸凝结器轴包括由开孔泡沫材料形成的外部覆盖物，其可以被诸如水或盐水的冷却剂饱和，以增加轴的热质量。 在其他实施例中，主动冷却将冷却剂输送到操作部位。 在其它实施例中，抽吸凝结器轴包括冷却套，通过该冷却套通过冷却剂来主动冷却仪器。 本文公开的改进的电外科吸入式凝结器可以具有降低的操作表面温度，这可能导致对相邻组织的不良影响的风险降低，并且可能导致减少的手术时间和改善的患者结果。
