Devices for surgical navigation systems

Trajectory frame assemblies for image guided surgical systems have a trajectory frame with a support column that can removably secure different components such as a tracking probe and an MER driver adapter to define and/or follow a desired intrabody trajectory. The trajectory frame assemblies include fins attached to the column support and a platform optionally with an X-Y table and/or arcuate reference brackets that are attached to the trajectory frame assemblies and can hold a reference frame with fiducials.

Minimally invasive surgical system

A patient-side support system includes a base, a platform movably coupled to the base, manipulator assemblies coupled to the platform, instruments, each of the instruments being coupled to a different one of the manipulator assemblies, each of the instruments including a body and a shaft extending from the body, and a guide tube common to the instruments. A first part of the shaft of each individual one of the instruments extends distally from the guide tube to the body. a second part of the shaft of each individual one of the instruments extends through at least a portion of the guide tube. The first part of the shaft of a first instrument of the instruments is articulatable between the body of the first instrument and the guide tube. The guide tube and the instruments are collectively rotatable about a longitudinal axis of the guide tube.

Method and apparatus for in-vivo cauterization of lesions and malignancies
09788883 · 2017-10-17 · ·

An in vivo capsule has a cauterization element that may be deployed by physician while in vivo for cauterizing a lesion, such as bleeding. Energy is transferred from outside of the patient's body to the capsule and specifically to the ablating element, such as via a resonance circuit. Accordingly, it is the object of the present invention to provide a method and apparatus for precisely cauterizing or ablating tissue in-vivo. Embodiments of the invention may provide an in-vivo device having a cauterization or ablation element incorporated therein and a system and method for controlled navigation of the in-vivo cauterization device through a body lumen.

Locally invasive surgical apparatus with manipulator for bone fracture treatment

The present invention provides a locally invasive surgical apparatus including a manipulator for scratching the bone at a fracture site, a drive arm on which the manipulator is mounted, and a controller for controlling the manipulator and the drive arm. Therefore, it is possible to carry out minimally invasive surgery during bone fracture surgery, thereby enabling simple and quick bone fracture surgery for a speedy recovery.

Endoscope with guide
09737196 · 2017-08-22 · ·

An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.

System and method for advancing, orienting, and immobilizing on internal body tissue a catheter or other therapeutic device

This invention provides a system and method that allows a therapeutic device, such as an atrial fibrillation microwave ablation catheter or ablation tip to be guided to a remote location within a body cavity and then accurately immobilized on the tissue, including that of a moving organ, such as the heart. In various embodiments, the system and method also enables accurate movement and steering along the tissue, while in engagement therewith. Such movement and engagement entails the use of vacuum or microneedle structures on at least two interconnected and articulated immobilizers that selectively engage to and release from the tissue to allow a crawling or traversing walking across the organ as the therapeutic catheter/tool tip applies treatment (AGE devices). In further embodiments that lack a movement capability (AID devices), the immobilizers allow a predetermined position for the introduced device to be maintained against the tissue while a treatment is applied to the location adjacent thereto. In the exemplary AID devices, variety of steering mechanisms and mechanisms for exposing and anchoring a catheter against the underlying tissue can be employed. In the exemplary AGE devices, a variety of articulation and steering mechanisms, including those based upon pneumatic/hydraulic bellows, lead screws and electromagnetic actuators can be employed.

FLEXIBLE SURGICAL DEVICES

A surgical device comprises a tube including a proximal segment and a distal segment and a plurality of force transmission elements coupled to the tube. The force transmission elements are actuatable to alter the distal segment of the tube between a flexible state and a stiffened state. The device also comprises a plurality of routing members. Each routing member is coupled to a wall of the tube. The routing members are configured to receive and route the force transmission elements along a length of the tube while permitting the length of the tube to flex and compress. The device also comprises a decoupling structure that generates a reduced force transmitted to the proximal segment when an applied force is applied to the distal segment by the force transmission elements.

20220031409 · 2022-02-03 ·

A medical device (10), preferably a micro robot for application inside a body, and more preferably for application inside a human body (2). The medical device (10) includes a body part (11) and a tail part (12). A recapture line (13) is attached to the tail part (12). The recapture line (13) has a tensile strength which is sufficient to pull back the device while the column strength of the recapture line (13) not sufficient to push the medical device (10).

Insertable device and system for minimal access procedure

The present invention provides a system and single or multi-functional element device that can be inserted and temporarily placed or implanted into a structure having a lumen or hollow space, such as a subject's abdominal cavity to provide therewith access to the site of interest in connection with minimally invasive surgical procedures. The insertable device may be configured such that the functional elements have various degrees of freedom of movement with respect to orienting the functional elements or elements to provide access to the site from multiple and different orientations/perspectives as the procedure dictates, e.g., to provide multiple selectable views of the site, and may provide a stereoscopic view of the site of interest.

SIGNAL-EMITTING AND RECEIVING MEDICAL DEVICES WHICH PROVIDE DATA FOR REAL-TIME MULTI-DIMENSIONAL ANATOMIC VISUALIZATION MAPS
20220304626 · 2022-09-29 ·

The present invention relates to the process of using signal-emitting and/or receiving objects or smart medical devices for image acquisition, and which can utilize a variety of external energy sources which are directly applied and/or incorporated into the host subject to produce a continuous and dynamic visual representation of the host subject on a computer display, which representation hereafter will be referred to as a visualization map. The derived images can be targeted, to small (i.e., focal) areas of clinical interest, to organ systems, or the entire body. The present invention provides a scalable method for continuous and dynamic imaging over prolonged periods of time, as dictated by the clinical context.
