A medical device may comprise a handle having at least one actuator, a shaft having a proximal end and a distal end, the proximal end connected to the handle, and a distal assembly connected to the distal end of the shaft, the distal assembly including an end effector. The handle may be configured so that a single hand of a user can operate the at least one actuator to (1) actuate the end effector, (2) rotate the end effector relative to the shaft, and (3) articulate a distal portion of the shaft.

A delivery system for delivering an implant to a first space within a body of a patient including an elongate delivery member having a proximal portion, a distal portion, a lumen and a receiving area, the receiving area dimensioned for receipt of the implant. A deforming member is movable with respect to the delivery member from a first position to a second position to apply a force to the implant to deform the implant positioned in the receiving area of the delivery member.

A tissue dissector includes a handle assembly including an actuator, a head portion including a blade member defining an aperture configured to receive tissue therethrough, and a lighting assembly configured to provide lighting to the aperture of the blade member. The blade member is operatively coupled with the actuator for rotation about the aperture.

In a handle unit for interventional procedure, a master device for interventional procedure, and a remote control interventional procedure system, the handle unit is gripped by an operator. The handle unit includes a gripper, a mode selection module and a linear motion module. The gripper is gripped by the operator. The mode selection module is equipped to the gripper, and selects one of motion modes including a linear motion mode, a rotational motion mode and a plane motion mode. The needle linearly moves with one degree of freedom in the linear motion mode. The needle rotationally moves with two degrees of freedom in the rotational motion mode. The needle moves in a plane with two degrees of freedom in the plane motion mode. The linear motion module performs the linear motion of the needle based on the selection of the mode selection module, and is equipped to the gripper.

A surgical instrument includes an outer tube configured to be gripped by a user, and a needle slidably disposed within the outer tube. The needle includes a needle lumen, a distal needle tip configured to pierce tissue, and an electrode disposed at the distal needle tip. The needle lumen opens to the distal needle tip such that the distal needle tip is configured to deliver fluid from the needle lumen to tissue. The electrode is operable to deliver RF energy to tissue for ablating the tissue. The needle is translatable relative to the outer tube between a proximal retracted position in which the distal needle tip is housed coaxially within the outer tube, and a distal extended position in which the distal needle tip is exposed from the outer tube and configured to pierce tissue.

A Catheter for the transfer of human embryos including an outer catheter characterized by an integrated element of transverse folds in the shape of an “accordion” at a specific distance from its tip. When being compact, the element of transverse folds is 1 cm long while the distance of its center from the tip of the catheter is 5.5 cm but can vary +/−1 cm. The element of transverse folds has the ability to bend, expand, compress and generally be configured in the desired shape and angle by the operating clinician in order to facilitate its passage through the cervical channel. The shape and angle are capable of being re-configured by the operating clinician if deemed necessary. The element of transverse folds is also capable of automatically adjusting in shape and angle during its passage through the cervix, following the anatomy of the cervical channel.

A purse-string applicator for use in an anastomosis procedure includes an introducer sleeve, a handle assembly, and a support ring. The introducer sleeve includes a tubular body portion having proximal and distal portions. A handle portion is disposed on the proximal portion of the tubular body, and an introducer portion is disposed on the distal portion of the tubular body. The handle assembly includes an elongate shaft portion and a release mechanism. The release mechanism is positionable distal of the distal portion of the introducer sleeve. The support ring is releasably engageable by the release mechanism of the handle assembly and includes an annular body portion and first and second rim portions. The release mechanism releasably retains the support ring adjacent the distal portion of the introducer sleeve. The purse-string applicator may be included in a kit along with an anvil assembly, an adapter assembly, and/or a circular stapling instrument.

A medical device comprising a handle extending between a first end and a second end, a first actuator coupled to the first end of the handle, a first shaft coupled to the second end of the handle, and a second shaft extending from the first shaft, the second shaft including a first articulation section and a second articulation section, wherein an articulation of the first actuator relative to the handle is configured to articulate the first articulation section, an articulation of the handle relative to the first shaft is configured to articulate the second articulation section, and the first articulation section and the second articulation section are restricted to articulating only in a first plane.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A surgical instrument (10), comprising: a surgical execution component (100), a linkage part (200), and a manipulation component (300), the distal end of the linkage part (200) being connected to the surgical execution component (100) and the proximal end of the linkage part (200) being connected to the manipulation component (300). The surgical instrument (10) uses the linkage part (200) having two rotational degrees of freedom, such that when the manipulation component (300) drives, by means of the linkage part (200), the surgical execution component (100) to rotate at a fifth rotational degree of freedom (R5) and/or a sixth rotational degree of freedom (R6), the swing directions of the surgical execution component (100) and the manipulation component (300) at a first rotational degree of freedom (R1) and a second rotational degree of freedom (R2) are consistent. Therefore, the surgical instruction (10) implements technical effects of improving the moving direction accuracy of the surgical execution component (100), improving the accuracy of the action of the surgical instruction (10), and facilitating surgical operations.
