摘要:
Surgical instruments are disclosed. Various non- limiting embodiments may include an elongated shaft (14) that has a distal end portion that is configured to operably support a circular staple cartridge (30) therein. A tissue acquisition shaft may be rotatably supported within said elongated shaft and have a distal portion that protrudes distally beyond the distal end portion of the elongated shaft. At least one tissue acquisition member may be pivotally attached to the distal end portion of the tissue acquisition shaft such that the tissue acquisition members are selectively pivotable from a retracted position to deployed positions upon application of a deployment motion thereto. A rotatable cutting member may be operably supported adjacent to the tissue acquisition member and being selectively rotatable about the central axis upon application of a cutting actuation motion thereto.

A tunneling tool for creating a pathway for implanting a therapy delivery element in a living body. The tunneling tool includes a malleable elongated shaft having a distal end. A sheath having a lumen is slidably positioned over a portion of the shaft. A primary handle secured to proximal end of the shaft permits a user to advance and manipulate the shaft and the sheath in the living body. A secondary handle with an opening is slidably positioned on the shaft between the primary handle and the sheath. The opening has a diameter less than an outside diameter of a proximal end of the sheath. A locking mechanism releasably engages the secondary handle to the primary handle. The sheath is retained in a desired location within the living body by securing the secondary handle relative to the living body as the primary handle is used to remove the shaft from the sheath.

A single use morsellator utilizes a disposable housing, cutting tube, battery and motor in combination with an attached and adjustable trocar to enable the surgeon to selectively utilize the cutting edge of the tube. The battery and control circuit are completely contained within the integral morsellator such that no separate components are needed.

An undercutting system ( 30 ) for preparing a region between ilium and sacrum for sacroiliac fusion. The undercutting system includes an insertion apparatus ( 34 ) and a cutting assembly ( 32 ). The cutting assembly is operably attached to the insertion apparatus. The cutting assembly is movable with respect to the insertion apparatus between a retracted configuration and an extended configuration.
摘要:
A motor-driven surgical instrument having a control assembly for controlling a switch of the instrument. The surgical instrument may comprise a motor control circuit, a drive member, and a slider. The drive member comprises a first shoulder at a first position and a second shoulder at a second position. A first portion of the slider interfaces the drive member such that the slider is moveable in a direction of movement of the drive member when either the first shoulder or the second shoulder of the drive member engages the first portion of the slider. A second portion of the slider actuates a switch of the motor control circuit when the drive member moves the slider to a first position relative to the first switch. In various embodiments, the switches of the control circuit are not embodied as a part of an IC.
摘要:
A device and method for extracting tubular structures are provided. An incision is made at a proximate and at a distal end of a tubular structure. An extracting device is inserted into and passed through a tubular structure until the operational head of the device extends past the distal incision. An actuator on the handle of the device is actuated, longitudinally extending the operational head of the device. The edge of a tubular structure is positioned axially in the mouth of a hook wire on the operational head. The actuator on the handle is released and the hook wire engages and captures the tubular structure. The user manually pulls the tubular structure, invaginating and removing it.
摘要:
End effectors with redundant closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises an elongate shaft having a proximal end and a distal end, a tool body disposed at the distal end of the shaft, a jaw movable relative to the tool body between a clamped configuration and an open configuration, a first actuation mechanism coupled with the jaw and operable to vary the position of the jaw relative to the tool body between the clamped configuration and the open configuration, and a second actuation mechanism coupled with the jaw. The second actuation mechanism has a first configuration where the jaw is held in the clamped configuration and a second configuration where the position of the jaw relative to the tool body is unconstrained by the second actuation mechanism.
摘要:
A subcutaneous fasciotomy is performed to relieve pressure due to compartment syndrome. A small incision is made in a patient's skin. A surgical instrument is advanced through the entry location, and moved between the skin and the fascia of the patient to a remote location, with a cutter of the instrument in a stowed configuration. After reaching the remote location, the cutter is deployed to pierce an initial opening in the fascia at the remote location. The fascia is maintained adjacent a blade of the cutter via a notch shape that traps the fascia. The instrument is then withdrawn back toward the entry location with the blade incising the fascia to relieve pressure in the muscle compartment. The surgical instrument is then removed through the entry incision.
摘要:
Apparatuses, systems, and methods involve using reduced pressure to position a portion of tissue in a cutting head and cutting the tissue to debride a tissue site. A cutting head includes a debridement conduit having a distal end and a proximal end. A portion of the debridement conduit adjacent to the distal end comprises a tissue treatment area. The cutting head also includes an opening to the tissue treatment area formed at the distal end of the debridement conduit. The tissue treatment area is adapted to receive the portion of tissue through the opening under reduced pressure. The cutting head also includes a selectively moveable cutting member associated with the debridement conduit at the tissue treatment area. The cutting member is for cutting the portion of tissue from the tissue site while the portion of tissue resides in the debridement conduit. Other methods, systems, and apparatuses are disclosed.
