摘要:
The invention relates to a disposable flexible membrane (1) suitable for adhesion to an objective lens, especially an objective of a camera for laparoscopic operations, the membrane (1) being transparent and comprising two opposite faces, a first face (4) comprising a hydrophobic surface, and a second face (6) comprising a surface of reversible adhesiveness. The invention further relates to a method for temporarily protecting the objective lens of a camera comprising the step of manually positioning such a membrane onto said lens and further manually removing said membrane from said lens.

The present disclosure relates to systems and methods for controlling pressure during percutaneous and endoscopic surgeries, including percutaneous renal procedures, endoscopic uterine procedures, transurethral endoscopic procedures for the bladder or prostate, or any percutaneous or endoscopic procedure. The system can include a sheath and/or endoscope each having an inflow port providing access to an inflow channel extending from the inflow port to a distal portion of the sheath, and an outflow port providing access to an outflow channel extending from the outflow port to the distal portion of the sheath. The sheath can also include a pressure sensor configured to generate a pressure measurement, and an electronic processor configured to control fluid through at least one of the inflow port and the outflow port based on the pressure measurement.
摘要:
The present invention relates to methods and systems for endoscopic fasciotomies. In certain embodiments such methods include dissecting tissue down to the fascia using an endoscopic dissector, lifting the fascia off tissue, vascular structures, muscle, and/or nerves, cauterizing and cutting the fascia using a bisector/bipolar device inserted through a cannula, retracting the cannula, and closing the incision site. A suction device introduced via the cannula may be used to apply suction to remove blood, tissue, irrigation fluid and/or other debris with the cannula in situ.

A treatment tool for an endoscope includes a forcep sheath, a first forcep cup and a second forcep cup which are attached to a distal end of the forcep sheath, and which cooperate with each other to be openable/closable as a whole, an operation wire which is movably arranged in the forcep sheath along an axial direction thereof, which is connected to the first forcep cup and the second forcep cup, and which opens/closes the first forcep cup and the second forcep cup when moved in its axial direction, wherein a sharp needle-shaped portion is formed on a distal end of the first forcep cup, the sharp needle-shaped portion extending farther than a distal end of the second forcep cup, and the sharp needle-shaped portion is arranged so that at least a portion thereof overlaps the second forcep cup.
摘要:
The present invention provides a system and method for creating a percutaneous fluidic connection. In one embodiment, the system includes an endoscope having an end cap with a tube that defines a distal cavity and an internal magnet circumferentially arranged around the distal end of the tube. The internal magnet is delivered into the patient's stomach and pressed against an inner wall of the stomach. An external magnet is placed on an external surface of the patient's skin corresponding to the location of the internal magnet and the inner and external magnets are coupled together. An incision is made through the skin to access the distal cavity, and an overtube containing a PEG device is inserted into the distal cavity. The magnets are decoupled and removed, leaving the overtube in place, which is subsequently retracted from the PEG device, allowing the PEG device to be anchored in place.

A medical treatment instrument includes an insertion tube configured to be inserted into a body of a patient; an image information acquisition device configured to be inserted in a withdrawable manner in the insertion tube; and a first conveyance path configured such that an object is conveyable into the insertion tube via the first conveyance path, the first conveyance path being located at an intermediate portion of the insertion tube so as to communicate with the insertion tube. The medical treatment instrument is configured such that the image information acquisition device is retractable to a retracted position proximal of the conveyance path when the object to be conveyed is conveyed through the insertion tube via the conveyance path.
摘要:
An apparatus including a cap that can be placed onto or removed from a bottle with an interference fit, for instance using a snap-type motion. The cap has a top portion and at least partially open bottom portion, where the cap is defined in part by an outer top portion, outer side portion, inner top portion, and inner side portion. The top portion of the cap has a tubing interconnect, and the tubing interconnect includes a passage therethrough. The cap includes one or more venting passages.
摘要:
An endoscopic device includes a proximal side contact portion coming into air-tight contact with an outer peripheral portion of the insertion section, and a cavity is defined between the insertion section and a fixed member to a distal direction side of the proximal side contact portion. In a protruding state of a hood, a first path which makes an inside of the hood communicate with the cavity is defined, and the hood is in air-tight contact with the fixed member over an entire circumference in circumferential directions at a distal side contact portion. In a housed state of the hood, a second path which makes the cavity to communicate with an outside of the fixed member is defined.
摘要:
The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.
摘要:
A valve apparatus device provides surgical instruments with sealable access to an inlet port of an endoscope instrument channel. The valve has a hollow body with a distal end that releasably attaches to the inlet port, and a flexible diaphragm seal dividing the body into a proximal chamber and a distal chamber. An instrument opening extends through the diaphragm seal for the passage of instruments therethrough, and connects the chambers together. The diaphragm seal is configured to seal with a surgical instrument inserted into the instrument opening. At least one fluid transfer member is provided to fluidly interconnect the proximal chamber to the distal chamber when the surgical instrument is sealed within the instrument opening.
