  • Patent number: 11364045
    Abstract: An ultrasonic forceps comprises a housing, an acoustic assembly, and a tine. The housing joins the acoustic assembly and the tine to the forceps and permits the tine to pivot relative to the acoustic assembly. The acoustic assembly comprises a transducer, a waveguide, and ultrasonic blade, and a waveguide sheath. The transducer is configured to generate ultrasonic vibrations directing the ultrasonic vibrations to the waveguide. The waveguide communicates the ultrasonic vibrations distally to the ultrasonic blade. The ultrasonic blade is configured to vibrate in response to the ultrasonic vibrations generated by the transducer. When the tine is pivoted relative to the transducer, the tine is configured to move toward the ultrasonic blade. Tissue may be grasped between the tine and the ultrasonic blade. The tissue may be denatured when the ultrasonic vibrations generated by the transducer vibrate the ultrasonic blade, thus resulting in the tissue being cut and/or sealed.

  • Patent number: 11266470
    Abstract: Described herein are systems, apparatus, and methods for precise placement and guidance of tools during surgery, particularly spinal surgery, using minimally invasive surgical techniques. Several minimally invasive approaches to spinal surgeries were conceived, percutaneous technique being one of them. This procedures looks to establish a skin opening as small as possible by accessing inner organs via needle-puncture of the skin. The percutaneous technique is used in conjunction with a robotic surgical system to further enhance advantages of manual percutaneous techniques by improving precision, usability and/or shortening surgery time by removal of redundant steps.

  • Patent number: 11259818
    Abstract: Methods for creating a void within a bone. An elongate member is directed into a tube of an access cannula, and a handle is positioned adjacent the access cannula. A working tip and pre-bent elbow are disposed within the tube such that the pre-bent elbow is straightened. The device remains slidable relative to the access cannula. A control assembly is actuated to distally move the shaft relative to the handle. Bone adjacent the tube of the access cannula may resist the working tip from protruding from the access cannula so as to displace the handle of the device proximally, or the handle may be manually maintained adjacent the access cannula. The pre-bent elbow and the working tip are moved beyond the distal end of the tube to be freed from the constraint of the tube of the access cannula to assume a curve within the bone.

  • Patent number: 11248686
    Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. The three axes of rotation for the three levers are parallel. Two of the levers may have half-cylinder surfaces at an end of the lever to receive a support point of the input gimbal plate. Two of the levers may be supported with one degree of rotational freedom orthogonal to the axis of rotation of the fulcrum. A spring may draw the second and third levers toward one another. Two levers may have stops that bear against the support points. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.

  • Patent number: 11241290
    Abstract: An apparatus includes a wrist, an end effector, a cable pair, and a transmission. A proximal wrist portion is coupled to a distal end portion of a shaft. Actuation of the wrist moves a distal wrist portion relative to the proximal wrist portion. The end effector is coupled to the distal wrist portion, and can be actuated to move relative to the wrist. The transmission is coupled to a proximal end portion of the shaft, and can move an end of the cable pair to actuate the end effector. The end of the cable pair is routed through a transmission cable path within the transmission. The transmission includes an adjustment mechanism having an input portion that receives a force exerted by the end of the cable pair. The adjustment mechanism is configured to change a length of the transmission cable path in response to a change in the force.

  • Patent number: 11234814
    Abstract: In one representative embodiment, a gripping and pushing device for a medical instrument comprises an elongated main body defining a lumen. The elongated main body comprises one or more deflectable portions that can be pressed radially inwardly toward a shaft of the medical instrument extending through the lumen. One or more elastomeric gripping layers can be secured to the inner surface of a respective deflectable portion at axially spaced apart attachment locations. The one or more gripping layers are axially deformable relative to the one or more deflectable portions between the attachment locations when manual pressure is applied to the one or more deflectable portions to press the one or more gripping layers against the shaft and move the shaft longitudinally into a patient's body.

  • Patent number: 11234705
    Abstract: An implant (500) comprises an elastic deformation portion (51) and a connection portion (52) connected with the proximal end (511) of the elastic deformation portion (51), wherein the elastic deformation portion (51) is covered by an elastic outer layer (55); the proximal end of the connection portion (52) is surrounded by a tightening ring (58); and the proximal end of the elastic outer layer (55) is covered by the tightening ring (58). Since the proximal end of the elastic outer layer (55) of the implant (500) is surrounded by a tightening ring (58), the elastic outer layer (55) is closely attached on the connecting portion (52) of the implant (500), such that the elastic outer layer (55) can be prevented from being rolled over from the surface of the implant (500) when the implant (500) is implanted, thereby improving safety of lung volume reduction surgery.

  • Patent number: 11234724
    Abstract: An instrument including an actuation gear mechanism that provides two functions of a tool. The actuation gear mechanism comprises a cam mechanism and a gear segment mechanism. The circumference of the cam disk of the cam mechanism—in a first section (?1)—is a spiral curve for generating a stroke for closing the forceps tool, while the circumference of the cam disk—in a second, adjoining, angular range (?2)—is circular. When the cam disk with the circular curved line biases the spring means, no further movement takes place on the output of the cam mechanism. Preferably, two congruent cam disks are provided, whereby these—together with the driving gear and the segment gear, as well as the shaft—form a one-piece plastic injection-molded part. The installation space between the cam disks can be utilized for a slide with a gear rack for shifting the knife.
