摘要:
A surgical device, comprising: an elongated shaft (20) having a first coupling (26); and a surgical instrument (250,2250) including at least one movable element (256,2256,264,2264), the elongated shaft including at least one rotatable drive shaft (30,32) configured to effect movement of the at least one movable element; characterised in that the surgical instrument has a second coupling, the second coupling being complimentary to and configured to couple with the first coupling; wherein the elongated shaft is configured to be inserted into a body via a first orifice and the surgical instrument is configured to be inserted into the body via one of the first orifice and a second orifice; and wherein the elongated shaft is configured to be-coupled with the surgical instrument via the first coupling and the second coupling after the elongated shaft is inserted into the body via the first orifice and after the surgical instrument is inserted into the body via the one of the first orifice and the second orifice.
摘要:
One embodiment of the apparatus comprises a housing with a sheath portion projecting distally therefrom. The sheath portion has a sheath with a lumen, and a bearing surface in the sheath lumen or aligned with the sheath lumen, and located at or near a distal end of the sheath. The implant is at least partially positioned in the apparatus, and comprises an implant body and a tether connected to the implant body. The tether extends from the implant body distally within the sheath portion and around the bearing surface, where the tether changes direction, and extends back proximally from the bearing surface along and within the sheath portion. The apparatus is configured to move the first tether portion proximally and thereby draw the implant body distally along and within the sheath lumen.
摘要:
This disclosure provides tools and implant techniques utilizing such tools to gain access to and implant a medical device, such as a medical electrical lead, within extravascular spaces. In one example, this disclosure provides a tool for creating a sub-sternal tunnel in a patient. The tool comprises a relatively straight guide member extending from a first end thereof to a second end thereof, a tunneling member extending from a first end thereof to a tip thereof, the tunneling member extending alongside and coplanar with the guide member, the first end of the tunneling member and the first end of the guide member being joined together, and a handle coupled to the guide member.
摘要:
A surgical instrument with a tissue-clamping end effector, where actuation of the instrument is locked out when the thickness of the tissue clamped in the end effector is not within a specified thickness range. The end effector may comprise a tissue thickness module that senses the thickness of the tissue clamped in the end effector. The surgical instrument also comprises a control circuit in communication with the tissue thickness module. The control circuit prevents actuation of a working portion of the end effector when the thickness of the tissue clamped in the end effector is not within the specified thickness range.
摘要:
A medical device includes a control handle (2-4) having an articulation joint actuator (4), a surgical end effector (1), and a passive articulating joint (10) connecting the end effector (1) to the control handle (2-4). The articulation joint actuator (4), when unactuated, holds the passive articulation joint (10) and, thereby, the end effector (1), in a substantially fixed articulation position, and, when actuated, releases the passive articulation joint (10) into a freely articulating state to permit free articulation of the end effector (1) with respect to the control handle (2-4) dependent upon external forces acting upon the end effector (1).
摘要:
An end effector assembly configured for use with a surgical instrument or surgical system includes first and second jaw members each including an outer jaw housing, a tissue-treating plate, and a longitudinally-extending channel therethrough. At least one of the first or second jaw members is pivotable relative to the other between a spaced-apart position and an approximated position. A cutting mechanism is configured to cut tissue grasped between the jaw members. The cutting mechanism may include an activation member coupled to a knife and configured to advance the knife transversely between the jaw members, a heat-activated elongated sheet configured to un-roll to advance a cutting edge thereof transversely between the jaw members, or a clutch and spring mechanism configured to deploy a knife longitudinally between the jaw members.
摘要:
Methods and devices are provided for preparing and implanting tissue scaffolds. Various embodiments of scribing tools (10,50) are provided that are configured to mark one or more predetermined shapes (38) around a defect site (36) in tissue (40). The shape or shapes marked in tissue can be used to cut a tissue scaffold (102,106,136,158) having a shape that matches the shape or shapes marked in tissue. In one embodiment, the scribing tool used to mark a shape in tissue can also be used to cut the tissue scaffold.
