摘要： In an insertion configuration, an endoscope assembly includes an insertion member with a distal end face and a working channel and further includes an instrument shaft extending through the working channel and an operative tip connected to the instrument shaft and extending in a plane oriented perpendicularly to the instrument shaft. The operative tip is positioned along the distal end face of the endoscope insertion member. The operative tip is separable from the distal end face of the endoscope insertion member by a distally directed motion of the instrument shaft along the working channel.

摘要： A medical instrument usable with an ultrasound-endoscope for performing a needle biopsy on a patient's internal body tissues usable at a surgical site not visible to the unaided eye or viewed endoscopically, comprises an elongate tubular member with a hollow needle element connected at its distal end, a sheath member housing said tubular member and needle element, an actuator subassembly with a shifter member operatively connected to elongate tubular member's proximal end, and a distal camming subassembly, said subassembly enabling a rotating motion of said needle member while handle actuator is moved in the forward direction. Upon inserting an ultrasound-endoscope into a patient and locating a mass, the fine needle with sharply pointed spoon shaped distal end is inserted into the mass aided by endoscopic and ultrasonographic guidance. Once in the mass, a camming action is initiated, causing rotation of the fine needle within the mass, resulting in a scooped out core biopsy. This instrument enables the performance of a fine needle aspiration requiring only one or two needle introductions, with a resultant core biopsy substantial enough for diagnostic purposes.

摘要： An endoscope sheath includes a web member disposable in a tubular configuration in engagement with an endoscope insertion member, the member being provided with a tear string in the form of a tensile member. The tear string preferably extends longitudinally along the web member. In addition, the tear string preferably extends from one end of the web member to an opposite end thereof and is disposed along a weakened area of the web member. The web member is provided in a plurality of regions with a layer of adhesive material. The adhesive material of at least one of the regions is permanent adhesive, whereas the adhesive material of at least another of the regions forms a separable bond. These regions extend along opposing longitudinal edges of the web member.

摘要： A needle biopsy instrument for retrieving a tissue sample from an internal organ such as needle biopsy forceps, includes a pushing surface for safely dislodging a tissue sample from the needle after the instrument containing the sample is retrieved from the patient using mechanical control means operated from the proximal handle to thereby avoid the risk of accidental cuts, punctures and other injuries to medical personnel while trying to manually remove the sample. The instrument has a cam mechanism, or other mechanical links scissor links for operating the cups and producing relative movement between the pushing surface and axis of the needle to cause a tissue sample to be moved toward and eventually off of the tip of the needle into a sample receiving cup. An axial reciprocating control member attached to either the needle or the pushing surface produces the relative movement and is manually controlled by a handle or other grip at the proximal end of the forceps. The needle is either retracted axially from the distal toward the proximal end of the device, or a pushing member attached to the distal end of an actuating cable or cable is moved distally along the axis of a stationary needle. A latch mechanism can be provided on the proximal end to release a biasing force to provide the relative movement between the needle and pushing member to slide a tissue sample off the needle.
