  • Publication number: 20240065747
    Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

The proximal section of the elongate shaft is detachably coupled to an electrosurgical controller such that the ring-shaped active electrode is operable with the electrosurgical controller and a dispersive electrode to electrosurgically make a circular-shaped incision through a tissue wall, carving a cylindrical-shaped tissue plug as the ring-shaped active electrode is advanced through the wall. The access sheath is advanced through the surgically created opening and without further dilation of the opening. The invention has particular applicability to the lung, and minimally invasive bronchoscopic procedures. Related methods are also described.

  • Publication number: 20240065761
    Abstract: A laser system for hard and soft biological tissues utilizes a laser (206), dye spray applicator (205), and a rinse spray applicator (212) in concert within a single handpiece (200) to create a computer programmable system that delivers a precise means of controlled ablation. The handpiece (200) is first used to apply dye (209) to a targeted treatment surface (210). Then it is used to apply a laser beam to the dyed treatment surface. This is followed by applying a rinse agent (215) through the same handpiece (200) to remove debris and combustion by-products. The steps are then repeated until the operation is complete.

  • Publication number: 20240065762
    Abstract: The disclosed technology provides for printing a 3D structure in-situ within a patient during a surgical procedure. The disclosed technology can include generating instructions for a 3D printer of a surgical robot to print a structure within the patient's body, simulating and verifying the instructions, and autonomously or semi-autonomously executing the instructions, once verified, during a surgical procedure. Generating the instructions for printing the 3D structure within the patient can be based on image data of the patient. Generating the instructions can also include selecting substrate materials that are both safe for the patient and having desired properties of the final printed structure. Modifications can be made to the instructions based on results from the simulation. The disclosed technology provides for application of safe substrate material directly to hard and/or soft tissues within the patient's body via an additive manufacturing process, such as 3D printing.

The disclosed apparatus designs and installs customized surgical implants to minimize the recovery of the patient. The system uses imaging data to identify the least invasive installation path, and determines the maximum dimensions of the surgical implant components. The system virtually segments the surgical implant into subcomponents, and modifies the subcomponents such that they can be inserted following the identified least invasive path.

    Abstract: Technologies for providing assistance to a surgeon during a surgical procedure are disclosed. An example method includes identifying a medical condition of a patient and recommending surgical procedures for treatment. An optimal surgical procedure is then determined based on correlations between the medical condition of the patient and outcomes of previous surgical procedures for other patients previously suffering from the medical condition. A 3D model of the patient may be created using current images of an affected area of the patient. Successively, a surgeon is trained using a Virtual Reality simulation. During the training, the surgeon may be allowed to provide annotations. Further, the recommended surgical procedures are based on medical data of the patient, including medical images.
