Surgical stapling devices are disclosed herein that improve on the disclosures of previous surgical stapling devices.

A multifunctional surgical instrument (1) is provided. The multifunctional surgical instrument (1) comprises a proximal portion (13) and two legs (14), each leg comprising a distal end (11, 12), wherein a default position of the multifunctional surgical instrument is an open position, wherein the distal ends (11, 12) of the legs (14) do not meet in the open position, characterized in that each leg (14) comprises an aspiration half-channel (26, 27), the proximal portion (13) comprises an aspiration connection (29) and at least one of the distal ends (11, 12) comprises at least one aspiration orifice (28), wherein the two half-channels (26, 27) are configured to form an air-tight and water-tight continuous channel (25) connecting the at least one aspiration orifice (28) to the aspiration connection (29) when the multifunctional surgical instrument is in a fully closed position and are configured to open the aspiration channel (25) when the multifunctional surgical instrument is not in the fully closed position.

Disclosed are an assembly for a surgical instrument and a surgical kit. The assembly comprises a separation member and a packaging box. The separation member and a surgical instrument switch between a first state and a second state by means of a clipping mechanism. In the first state, the separation member is connected to the surgical instrument. In the second state, the separation member is detached from the surgical instrument. The packaging box comprises an accommodation portion, and further comprises an operating member. The operating member drives the clipping mechanism to switch the separation member from the first state to the second state. The separation member is used for stripping the target tissue. The packaging box can not only provide packaging for the separation member, but also serve as a disassembling tool of the separation member relative to the surgical instrument.

An access system includes a proximal handle, an overtube coupled to the handle, and an endoscope port extending through handle and overtube sized for receiving an endoscope therethrough. The overtube includes anatomic wall securing system that secures a distal portion of the overtube within a hole in the anatomic wall. The overtube is provided with a shaped distal portion or a controllably shapeable distal portion that aids in directing an endoscope inserted through the port to a particular location within the peritoneal cavity. The access system includes a system for insufflating/deflating the peritoneal space separately from the body cavity accessible via a natural orifice. The access system includes a closure system to cinch closed the hole made in the anatomical wall after the access system has been removed from the hole. Methods are provided for inserting the access system through the anatomical wall to perform intra-abdominal surgery.

A medical instrument has a shaft with a longitudinal axis, a jaw head on a distal end of the shaft having two jaw parts, at least one of the jaw parts being pivotable about a pivot axis extending transversely to the longitudinal axis, the pivotable jaw part having a wheel portion with toothing mounted about the pivot axis, at least one actuation element having a distal end portion with toothing that meshes with the toothing of the wheel portion such that movement of the actuation element along the longitudinal axis pivots the pivotable jaw part, control elements at a proximal end of the shaft controlling movement of the actuation element, said distal end portion with toothing is flexible, one of the jaws having a hollow space arranged distally to the pivot axis, wherein the distal end portion comes in or out of the hollow space when moving the actuation element.

A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

A device and method for visualization of the intravascular creation of autologous valves, and particularly venous valve, is disclosed herein. One aspect of the present technology, for example, is directed toward a delivery catheter that can include a lumen configured to receive a dissection assembly and a trough having a plurality of transducers electrically coupled to a proximal portion of the delivery catheter. At least one of the transducers can be configured to emit a signal towards a portion of a blood vessel adjacent the trough, and at least one of the transducers can be configured to receive a reflection of the emitted signal.

Apparatus and methods for internal surgical procedures are disclosed. The apparatus and methods may involve supporting internal body locations, creating submucosal separations (blebs), and/or for resecting mucosal tissue separated from underlying tissue by a bleb.

Described are methods and apparatus for use in supporting tissue in a patient's body. In some embodiments, the patient's breast is supported. In some embodiments, the methods provide ways of supporting and adjusting tissue, and the apparatus includes components and embodiments for supporting and adjusting the tissue. Some embodiments include a supporting device, having a first portion, a second portion, and a support member positioned between the first portion and second portion. Some embodiments include advancing the first portion of the supporting device into the body to a first location in the body; advancing the second portion of the supporting device into the body to a second location in the body; securing the first portion of the supporting device at the first location; and shifting soft tissue in the body with the support member.
