摘要:
A dual one-way check valve arrangement (300) that may be used for assessing an operating condition of at least one of first and second check valves (304, 308) situated in series along/within a section of a patient-specific section of tubing (244). A pressure sensor (332) may be associated with at least part of the flow path between the first and second check valves (304, 308) and may be operable to provide an indication of a failed condition of at least one of the first and second check valves (304, 308). In one embodiment, the pressure sensor (332) may change from a first state to a second state upon fluid pressure within the flow path between the first and second check valves (304, 308) falling below a predetermined level. For instance, the predetermined level may be a cracking pressure of at least one of the first and second check valves (304, 308). The change in state may be visually discernible on an exterior of the pressure sensor (332).

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.

In certain embodiments, a syringe mount of the invention may include a plate, an actuator, and one or more movable members located between the plate and the actuator. Each of the plate and the actuator may have an orifice defined therein, and an imaginary reference axis of the syringe mount may extend through one or both of these orifices. The actuator may be movable relative to the plate in a direction substantially perpendicular to the reference axis. Further, the moveable member(s) may be designed to move (e.g., pivot) toward the reference axis due to movement of the actuator from a first position to a second position and to move (e.g., pivot) away from the reference axis due to movement of the actuator from the second position to the first position.

An injection device (120) used in delivering medical fluids to a patient is provided. The injection device (120) may include a syringe plunger driver (126a) and a syringe (140). The syringe (140) may include a syringe data storage device (134). The injection device (120) may include a communication device (132a) disposable in each of attached and detached conditions. The communication device (132a) may be operable to read a data storage device (134) within its field of view. When the communication device (132a) is attached to the injection device (120) and the syringe (140) is installed on the injection device (120), the communication device (132a) may be operable to read the data storage device (134) associated with the syringe (140). When in a detached condition, the communication device (132a) may be operable to be hand manipulated such that various other data storage devices (134) may be read.
摘要:
A syringe plunger drive assembly (132) for advancing a syringe plunger (90a/b) in at least one direction (e.g., to deliver fluid). In one embodiment, this syringe plunger drive assembly (132) may be constructed of all non-ferrous components and includes a piezoelectric pump (110) that supplies pressurized hydraulic fluid to a syringe plunger driver (134). The syringe plunger driver (134) may be in the form of a single acting hydraulic cylinder including a piston rod (140) movable in first and second generally opposing directions (e.g. forward and rearward). A valve (152) and a reservoir (154) may be fluidly interconnected between the piezoelectric pump (110) and the syringe plunger driver (134) to facilitate the pumping of hydraulic fluid to the syringe plunger driver (134).

An ultrasonic surgical instrument includes a reusable handle assembly and a removable and disposable shaft assembly. The handle assembly includes a trigger, a housing having a distal aperture formed in a distal end of the housing, and a drive member in communication with the trigger to actuate the drive member. The shaft assembly includes a proximal shaft portion, a rotator knob having a coupling feature, a transmission assembly extending distally from the proximal shaft portion, and an end effector coupled to the distal end of the transmission assembly. The drive member of the handle assembly is removably coupled to the proximal shaft portion of the shaft assembly. Another version includes a drive member of the handle assembly configured to removably engage a proximal shaft portion of the shaft assembly via a biasing member. Another version includes a waveguide of the transmission assembly non-threadably coupled to a transducer.

An electrosurgical device includes a body, an end effector, a cutting member, and a shaft. The end effector comprises a pair of jaws and at least one electrode that is operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively articulate the end effector relative to the shaft. The body includes a controller operable to selectively actuate the articulation section. The controller may include a trigger that also drives the cutting member, a rotator that also rotates the shaft and end effector, a wedge-shaped pivoting member, a pivotally coupled pair of housing portions, or a pivoting cam member, etc. A release member may selectively release the articulation section from the controller, allowing a resilient bias to return the end effector into alignment with the shaft.
摘要:
The disclosed embodiments provide for a syringe mount for a medical fluid power injector. The syringe mount is designed to hold a syringe so that a drive of the medical fluid power injector can move a plunger of the syringe to expel medical fluid from the syringe. The syringe mount comprises a first syringe clamp comprising a first arcuate surface, and a second syringe clamp comprising a second arcuate surface, wherein the first and second syringe clamps are in opposing relation to one another such that the first arcuate surface faces the second arcuate surface, and wherein the first and second syringe clamps are adapted to translate in opposite linear directions toward and away from one another to engage and disengage a syringe located therebetween.
摘要:
A surgical instrument includes a temperature sensor and a control unit that is operable to deactivate an end effector of the surgical instrument. In some versions the temperature sensor detects the temperature of a transducer, while in others the temperature sensor detects the temperature of the end effector. The surgical instrument may also include a trigger and a trigger position sensor. A force sensor or a position sensor may be included to determine the force and/or position of the transmission assembly. The end effector may also include a force sensor or a micro coil. A surgical instrument having a sensor may be included in a surgical system that includes a control unit and a remote controller. In some instances the remote controller may have one or more force-feedback components. In addition, a device interface and a surgeon interface may be included to remotely adjust the settings of the control unit.

An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.
