A visual tweezer includes a main shell, a connecting shank, a tweezer assembly, a driving assembly, a circuit assembly and a camera assembly. The driving assembly including a press member, a push member, and a connector, wherein the push member is arranged on one side of the connecting shank close to the main shell; the connector is connected to the push member and is connected to the tweezer assembly through the second opening and the second storage cavity; the press member is abutted with the push member and is used for driving, when pressed by an external force, the push member to move in the preset direction, so that the connector moves in the preset direction to drive the tweezer assembly to be opened or closed. It can be convenient to control opening and closing of the tweezer, and operations of the user are facilitated.

A surgical clamp including a pair of jaws, which may be used to ablate or create lesions in tissue. In an exemplary embodiment, the jaws are movable between an articulated position in which the jaws are separated and not parallel to one another, an opened position in which the jaws are separated and substantially parallel to one another, and a closed position in which the jaws are adjacent and substantially parallel to one another.

An endoscopic includes a handle, a tubular member, a control member, and an end effector assembly. The handle has a stationary member and a movable member. The movable member includes a constrained curved path for passage of the control member. The tubular member has an end coupled to the stationary member and a distal end rotatably coupled to the end effector assembly. The control member extends through the curved path, the tubular member, and is coupled to the end effector assembly. A knob is attached to the movable member and control member. Displacement of the movable member relative to the stationary member causes actuation of the end effector assembly, and rotation of the knob on the movable member causes the control member to rotate within both the constrained curved path and the tubular member, and results in rotation of the end effector assembly.

A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.

A surgical clamping device includes a tool assembly having a first jaw and a second jaw. The first jaw includes a mount portion and a clamping portion and the second jaw includes a proximal portion having first and second side walls defining a central cavity. The mount portion of the first jaw is received within the central cavity of the second jaw. One of the mount portion of the first jaw or the proximal portion of the second jaw includes first and second cam members and the other of the mount portion of the first jaw or the proximal portion of the second jaw defines at least one cam slot that receives the first and second cam members. The at least one cam slot is configured to cause parallel closure of the first and second jaws.

According to exemplary embodiments of the present disclosure, devices, systems, and methods for endoscopic procedures may include an end effector of a grasping system having a first arm and a second arm. The first and second arms may extend from a common proximal joint. The first and second arms may be formed of a self-expanding material and may have a spring force to set the arms in an unconstrained open position. The first and second arms may have an arc shape such that a distal tip of each first and second arm are configured to close as the first and second arms are actuated to a constrained closed position. A catheter may include a locating element at a distal end of a flexible tube. The locating element may be configured for locating the grasping system.

According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

A stone retrieval device includes a sheath and a stone retrieval basket that includes a distal region with a plurality of basket wires and a proximal region with one or more core wires. The stone retrieval basket is contained within the sheath and is movable out a distal opening of the sheath to cause the plurality of basket wires to open into a basket shape. The stone retrieval device further includes a lock mechanism that locks the position of the stone retrieval basket with respect to the position of the sheath and a basket force controller that includes a first and a second control stage. The first control stage includes a sensor for measuring force on the stone retrieval basket when the lock mechanism is in an unlocked position, and the second control stage includes a sensor for measuring force when the lock mechanism is in a locked position.

A surgical instrument handle operates a microsurgical instrument on a surgical instrument head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a ring mounted on the rod for reciprocating movement. The ring is operatively associated with the surgical instrument head for operation of the microsurgical instrument of the head. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod to cause operation of the surgical instrument head.

Laparoscopic Knot Applicator is a tool designed to facilitate application of surgeons Knot (FIG. 2) to ligate vessels and structures during laparoscopic procedures. Applying the secure surgeons knot in any surgical procedure is a life saving basic skill but it is a difficult task in laparoscopic surgeries. Operation of this tool (FIG. 3) ensures application of safer and secure knots compared to currently available techniques like clips, loops and Harmonic scalpel. Simple design of this tools enables laparoscopic surgeon to apply very secure conventional surgeons knot easily during laparoscopic surgeries even in a very limited surgical space. Cleaning and the sterilization of the instrument which is essential in surgical procedures is very easy as there are no electronic parts incorporated.
