An endoscopic surgical device that can suitably puncture a body wall with an overtube that having two insertion passages is provided. In a case where a body wall is punctured with the overtube that has two insertion passages through which medical instruments are inserted and that has openings of the insertion passages in a distal end surface, distal end parts of two needle parts of an inner needle are disposed to protrude from the openings in a case where the inner needle is mounted. Accordingly, a distal end portion of the overtube has a tapered shape, cutting blade parts are disposed in the same straight line as seen from a distal end side, and an insertion load is reduced.

This endoscopic surgical device includes: an endoscope; a treatment tool; and a mantle tube. The inside of the mantle tube is partitioned by a partition wall member provided with an endoscope guide groove and a treatment-tool guide groove, to form an endoscope insertion passage and a treatment-tool insertion passage. An endoscope fixation tool and a treatment-tool fixation tool are respectively disposed inside the endoscope guide groove and the treatment-tool guide groove. The endoscope fixation tool advances and retracts in conjunction with the endoscope insertion part inserted through the endoscope insertion passage. The treatment-tool fixation tool moves in conjunction with the treatment-tool insertion part inserted through the treatment-tool insertion passage. When a coupling ring externally fitted to the partition wall member interlocks the endoscope fixation tool with the treatment-tool fixation tool, the endoscope insertion part also moves in conjunction with the advancement and retraction of the treatment-tool insertion part.

A cannula assembly for use in robotic surgery is disclosed that includes a robotic cannula having a housing with an open end and a tubular portion extending distally from the housing, the tubular portion being dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, an adapter assembly configured for engagement within the open end of the cannula housing and including a tubular body with a passage supporting a primary seal dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, and an insert tube dimensioned to extend through the passage of the body portion of the adapter assembly and the tubular portion of the robotic cannula, the insert tube including a head portion with a passage supporting a secondary seal dimensioned to accommodate a surgical instrument having an 8 mm diameter.

A teleoperable medical system comprises a manipulator arm and a cannula mount coupled to the manipulator arm. The manipulator arm comprises an interface configured to operably couple with a medical instrument. The cannula mount is configured to removably mount a cannula to the manipulator arm in a position to permit removable insertion of the medical instrument through the cannula. The cannula mount comprises a receptacle configured to receive an attachment portion of the cannula in a mounted state of the cannula, and a reader positioned to be in magnetic field sensing proximity to the attachment portion of the cannula in the mounted state of the cannula. The teleoperable medical system comprises a controller configured to receive output signals from the reader and determine identification information about the cannula based on the output signals.

A treatment device used together with an endoscope, has a guide pipe and a movement mechanism. The guide pipe has a first pipe having a curving portion and a second pipe continuous with a proximal side of the curving portion. The curving portion has, in its inner circumferential surface, a bent surface bent to the second pipe, and bending the flow direction of the fluid discharged from the distal end of the sheath in a state where the distal end of the sheath is located near the distal end of the second pipe. The movement mechanism protrudes a distal surface of the insertion portion from the distal end of the sheath and brings the distal surface closer to or into abutment with the bent surface in a state where the distal end of the sheath is disposed near the distal end of the second pipe.

Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

An interrogation and detection system for detection of surgical implements within a patient's body, the system including One or more RFID tags affixed to a surgical implement within the patient's body. Each RFID tag being configured to transmit a return signal when energized, and a remote signal generator configured to generate an energizing signal for the one or more RFID tags. The signal generator operably coupled to the in-vivo introducible antenna via a communication cable. The system further includes an in-vivo introducible antenna configured to be inserted through a trocar-cannula assembly into a surgical site within the patient's body. Wherein the tubular channel defines a shape having a dimension “D1”, such that the dimension “D1” of the tubular channel is less than the dimension “D2” of the in-vivo introducible antenna.

A cannula for passing surgical instruments through tissue. In some instances, the cannula may include a distal flange flexible between a radial configuration and a longitudinal configuration. In some instances, the cannula may also include an actuator configured to move the distal flange between the radial configuration and the longitudinal configuration. In some instances, the cannula may include a valve disposed within the lumen of the cannula, and a cap configured to secure the valve to the cannula. The valve may include a body member having a base and first and second opposing walls extending from the base. In some instances, the valve has an arcuate cutout in the lower surface configured to fit around an instrument shaft inserted therethrough. In some instance, the cannula includes a slit extending an entire length of the cannular to permit an instrument shaft to be inserted and/or removed laterally.

Interspinous process implants are disclosed. Also disclosed are systems and kits including such implants, methods of inserting such implants, and methods of alleviating pain or discomfort associated with the spinal column.
