Hemostatic clipping devices and methods

A tissue clipping apparatus, comprises a flexible, elongate member, a proximal end of which remains external to the body accessible to a user while a distal end of the flexible member is inserted into the body to a location adjacent to target tissue to be clipped and a control wire extending through the flexible member in combination with a capsule releasably coupled to a distal end of the flexible member and a clip a proximal portion of which is received within the capsule. A joint releasably coupling the clip to the control wire, includes a yoke extending around a proximal end of the clip and a frangible link which fails when subject to a predetermined force to separate the clip from the control wire.

A device (10) for capturing a guide wire (50) comprises a snaring device (20, 30) and an auxiliary catheter (40). The auxiliary catheter (40) is configured to slidingly accommodate the guide wire to be caught so as to extend a distal end (47) thereof beyond the distal end of the guide wire in order to be caught by the snaring device (20, 30) while the guide wire (50) is in a retracted position in the auxiliary catheter (40). The auxiliary catheter preferably comprises a portion which is at least partially echo-transparent and/or radio-transparent and an end portion (44) which is radio-opaque and/or echo-opaque.

Systems and methods for tissue removal

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Adapter assemblies for interconnecting surgical loading units and handle assemblies

An adapter assembly configured to be coupled to a surgical loading unit includes a switch, an elongated member, and an annular member. The switch is configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly. The elongated member is in communication with the switch and is resiliently biased in a distal direction toward a locking position in which the switch is toggled. The annular member is disposed adjacent the elongated member and is rotatable between a first orientation, in which the annular member prevents distal movement of the elongated member, and a second orientation, in which the elongated member moves distally to toggle the switch.

ENDOSCOPIC STAPLER AND STAPLE REMOVER

Disclosed is an endoscopic stapler that can be operated through the small working channel of a laryngoscope, other rigid endoscope, or a natural orifice to safely and effectively connect tissues permanently or semi-permanently. The endoscopic stapler apparatus includes a handle including a trigger, an outer shaft coupled to the handle, and an inner shaft with prongs positioned at a distal end of the inner shaft. The endoscopic stapler further includes a hook, wherein the hook and prongs are positioned to capture a staple at a tip of the prongs, wherein a proximal end of the inner shaft is coupled to the trigger, and wherein activation of the trigger causes the prongs to translate away from the handle causing the prongs to bend and close the staple.

SURGICAL TOOL
20230210509 · 2023-07-06 · ·

A surgical tool includes a slider, converters, and transmission wires. The slider is disposed movably in a linear direction relative to a main body, the main body including at least a treatment portion configured to perform a medical procedure. The converters move for a converted movement amount which is obtained by converting a movement amount of the slider with a magnification factor. The transmission wires transmit the converted movement amount to a treatment portion of the surgical tool.

STEERABLE MEDICAL DEVICE, HANDLE FOR A MEDICAL DEVICE, AND METHOD FOR OPERATING A MEDICAL DEVICE
20230211127 · 2023-07-06 ·

A handle for a medical device includes a handle body and a knob that is rotatable with respect to the handle body. A first gear is associated with the knob. A slide assembly is housed within the handle body or the knob. The slide assembly includes a first lead screw. A second gear is associated with the slide assembly. A third gear is housed within the handle body or the knob and is coupled between the first gear and the second gear. Rotation of the knob drives rotation of the first gear, rotation of the first gear drives rotation of the third gear, rotation of the third gear drives rotation of the second gear, and rotation of the second gear drives rotation of the lead screw.

Apparatus for connecting body tissues
11547402 · 2023-01-10 ·

The invention relates to a device for connecting body tissues with a head part, which has a longitudinal axis and can be pushed into a body opening, wherein a plurality of tissue staples are accommodated in the head part in a storage position which tissue staples consist of a linear main section and two engagement sections projecting perpendicularly therefrom and are each aligned in a first plane which is substantially perpendicular to the longitudinal axis. Optimal usability in the human body is achieved in that a hydraulic cylinder and/or a cylinder rod are at least partially arranged in the interior of the space which lies between the engagement sections of the tissue staples in the storage position, and preferably that the cylinder rod is firmly connected to a slider.

Optical bulb for surgical instrument port

An optical bulb for a medical device includes first and second bodies. The first body has a substantially hemispherical distal side. The second body extends from the first body and includes a mechanical connection point at or near the proximal side of the second body. An instrument channel extends through the optical bulb from the proximal side of the second body to the distal side of the first body. An imaging channel extends an aperture defined in the proximal side of the second body and terminates between the proximal and substantially hemispherical distal sides of the first body. The distal end of the imaging channel is substantially hemispherical. The first body is configured and arranged to provide a substantially uniform image path within a field of view of a camera disposed in the imaging channel.

Redeploy able tissue retrieval system

A tissue retrieval system including a tissue retrieval bag deployable by an actuator from an introducer and suspended in an open configuration by support arms can be serially redeployed between a partially or fully stowed configuration and a first deployed configuration to be used in procedures to collect multiple samples. The system can include defeasible proximal and distal stop mechanisms to limit movement of the actuator for serial redeployment. The tissue retrieval system can include a retention latch to couple a bead of the tissue retrieval bag to the actuator with the retrieval bag in the first deployed position and a user-selectable deployment release to allow deployment of the retrieval bag to a fully deployed position where it is released from the actuator. A bead stop is positioned to engage the introducer to prevent reintroduction of the bead and bag into the introducer once the bag has been fully deployed.
