A medical device includes an endoscope head which is designed to be detachably connected to endoscope tubes. The endoscope head has a longitudinal channel between a proximal end and a distal end of the endoscope head for receiving an endoscope tube. At least one measuring channel is arranged in the endoscope head. The measuring channel has at least one inner connection opening, which is connected to the longitudinal channel, and at least one outer connection opening, which is arranged on the outside of the endoscope head. The outer connection opening can be connected to at least one measuring channel in a measurement adapter which can be detachably coupled to the endoscope head.

An endoscope connector for connecting an endoscope to an external apparatus, includes: an exterior member including a first opening and a second opening on end part side, the first opening and the second opening respectively exposing, to an outside, predetermined members of the endoscope to be connected to the external apparatus; and a supporting member that is disposed inside the exterior member and holds the predetermined members, in which the supporting member includes an insertion hole that faces a region on the end part side of the exterior member, the region being different from the first opening and the second opening.

The invention discloses a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same. The system comprises a main tube, which is contiguous with the sheath tube and has an end for an endoscope insertion. The sheath tube comprises an inner sheath and an outer sheath joined together in a sleeve type. There is a space between inner and outer sheath. The inner sheath is connected to main tube, together building a channel via which the endoscope is inserted and withdrawn. The sheath tube is connected to main tube after completing puncture and dilation, then endoscope system is introduced for observation and operation. The present invention provides a percutaneous puncture and dilation visible irrigation-suction system and a method of using the same, with a continuous controllable visible negative pressure aspirator, achieving high irrigation and powerful suction efficiency, as well as clear endoscopic view.

In various aspects, a microsurgical apparatus disclosed herein includes a shaft having a shaft distal end, a shaft proximal end with a handle mounted to shaft proximal end. The microsurgical apparatus includes a tool package having an actuator at a tool package proximal end of the tool package and a tool at a tool package distal end of the tool package. The actuator cooperates mechanically with the tool. A sleeve lumen disposed within the tool package slidably receives the shaft for releasable lockable engagement of the tool package proximal end with the handle and with the shaft distal end being generally coextensive with the tool package distal end. Light source(s) and image sensor(s) located proximate the shaft distal end allow viewing of the tool when the tool package is mounted to the shaft. Exemplary methods of use of the microsurgical apparatus are also disclosed herein.

An endoscope for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

An endoscope having a handle including a frame, a fluid handling device secured to the frame via an interface, the fluid handling device comprising a fluid passage having a first fluid opening, a tube in fluid communication with the fluid opening of the fluid handling device, and shell parts enclosing a cavity accommodating the frame, the tube, and at least partly the fluid handling device therein, wherein, at least prior to enclosing the frame, the tube, and at least partly the fluid handling device within the cavity of the shell parts, the interface and the tube are configured to permit movement of the fluid handling device relative to the frame within a pre-determined boundary comprising a first position and a second position separated by a distance.
