摘要： Various surgical devices and methods are provided for monitoring and regulating tissue compression and cutting to improve tissue effect. In general, these devices include a handle portion, an elongate shaft, and an effector disposed at a distal end of the shaft and configured to engage tissue. In one embodiment, one or more sensors can be positioned at various locations on the device and can determine a force applied to tissue engaged by the end effector. When the force exceeds a threshold, a notification signal can be issued to a user. In another embodiment, a sensor can determine an amount of current moving between jaws of the end effector and a controller can slow a speed of the cutting element when the sensed current exceeds a threshold amount.

摘要： Various embodiments of surgical robot control systems are disclosed. In one example embodiment, the surgical robot control system comprises a housing. A controller is located within the housing and is coupled to a socket. The socket receives a handheld surgical user interface therein to control a surgical instrument. The surgical instrument is connected to the surgical robot and comprises an end effector and a mechanical interface to manipulate the end effector. The mechanical interface is coupled to the controller. At least one sensor is coupled to the controller and the socket to convert movement of the handheld surgical user interface into electrical signals corresponding to the movement of the surgical instrument. At least one feedback device is coupled to the controller to provide feedback to a user. The feedback is associated with a predetermined function of the surgical instrument.

摘要： Surgical devices and methods are described herein that provide improved motor control and feedback, thereby combining advantages of manually-operated and powered surgical devices. In one embodiment, a surgical device includes a proximal handle portion that includes a motor, a distal end effector coupled to the handle portion, and a cutting element configured to cut tissue engaged by the end effector, wherein the motor is configured to supply power that moves the cutting element. The device also includes a motor control mechanism configured to cause the amount of the power to dynamically change in response to a manual user input when the cutting element is moving.

摘要： Methods and devices for allowing articulation of an end effector on a surgical instrument are provided. In one embodiment, a surgical device can include a flexible neck portion having an end effector coupled to a distal end thereof. The flexible neck portion is configured to bend to as to allow the end effector to articulate. The flexible neck portion can include a monolithic flexible outer shell defining an inner lumen extending therethrough. At least one flexible divider can be disposed within the inner lumen such that it separates the outer shell into elongate pathways configured to receive articulation members extending through the shaft assembly and the flexible neck and coupled to the end effector to cause articulating movement thereof.

摘要： Surgical devices are provided having power-assisted or fully powered jaw closure. The devices herein generally include a handle portion, an elongate shaft, and an effector having first and second jaws configured to engage tissue. A motor and one or more compression springs can be operatively coupled, and activation of the motor can compress the spring(s) to reduce the amount of user supplied force to compress tissue between the jaws. In some embodiments, the devices can be configured to regulate an amount of compression applied by the jaws prior to, during, and/or after cutting of the tissue to promote hemostasis. For example, the devices can include sensors, processors, and/or other components that analyze data indicative of tissue type and tissue load. Based on this feedback, the device can automatically adjust the amount of compression or energy applied to the tissue to seal the tissue.

摘要： An apparatus includes a body, a shaft assembly, an articulation section, an end effector, an articulation connector, and an articulation drive assembly. The shaft assembly extends distally from the body. The end effector is connected to the articulation section such that the end effector is configured to deflect relative to the longitudinal axis of the shaft assembly. The articulation connector is configured to translate relative to the shaft assembly to deflect the end effector relative to the longitudinal axis. The articulation drive assembly is configured to translate the articulation connector relative to the shaft assembly. The articulation drive assembly includes a rotatable housing and a first lead screw assembly. The first lead screw assembly includes a first half and a second half. The first lead screw assembly is slidably coupled with the shaft assembly and is configured to translate in response to rotation of the rotatable housing.

摘要： A surgical instrument including a handle assembly and an end effector, including a first jaw pivotably coupled to a second jaw, is disclosed. The handle assembly may comprise a jaw position sensor comprising a switch, a closure trigger, and a clamp spring actuatable by the closure trigger. The closure trigger may be configured to: rotate between a first position and a second position, wherein the first position corresponds to the first and second jaws in an open position and the second position corresponds to the first and second jaws in a closed position, and activate the switch of the jaw position sensor at a predetermined rotated position. The clamp spring may be configured to: cause the first and second jaws to transition between the open position and the closed position, and apply a force to the first and second jaws.
