11452844 · 2022-09-27 · ·

A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter.

20220265283 · 2022-08-25 ·

Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.

CIRCUMCISION DEVICE
20220265299 · 2022-08-25 ·

Described herein is a circumcision device including a support having a glans penis locating member mountable thereto. The support is provided with at least one pillar that includes a proximal end and a distal end, the distal end being fastened to a crush plate. The pillar facilitates movement of the crush plate relative to the support. A locking device is moveable between a locked position and an unlocked position, such that axial movement of the pillar is inhibited in the locked position and enabled in the unlocked position. The locking device is at least partially hidden by the support. A blocking device is interposed between the support and the crush plate to block movement of the crush plate towards the support past a predefined point to inhibit the locking device from becoming exposed.

Surgical bone preparation instrument and assembly comprising such an instrument
11234717 · 2022-02-01 · ·

This surgical bone preparation instrument (1) comprises a main body (5) terminated by a contacting surface (50) adapted to abut on a bone (B), and a sliding body (7) equipped with a cutting element (3) and which is movable in translation with respect to the main body (5). The bone preparation instrument (1) includes a cutting depth control ring (11) that is adjustable by a single hand, which forms an abutment surface (110) against the movement of one of the main body (5) and the sliding body (7) when the sliding body (7) reaches an adjusted cutting depth (D) corresponding to an adjustment position of the control ring (11).

Forceps jaw flanges

Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.

Collet for an endoscopic needle knife

An endoscopic needle knife may include a collet coupled to a distal end of a tubular member of the needle knife. A cutting wire may be disposed within a cutting wire lumen of the tubular member and a central lumen of the collet. An inner surface of the collet body may create a frictional force between the cutting wire and the inner surface so that the cutting wire is resistant to longitudinal movement relative to the tubular member caused by external forces. The frictional force may also be less than a longitudinal force exerted on the cutting wire by a handle assembly or other control mechanism that is used to longitudinally move the cutting wire within the tubular member and the collet.

REMOVABLE SPLIT CANNULA FOR PLACEMENT OF ELECTRODES
20220265335 · 2022-08-25 ·

A method of inserting an electrode into a cranial cavity of a cranium can include determining a length, between a target within the cranial cavity and a proximal end of a multipiece cannula, of the electrode for insertion of the electrode to the target. A distal end of the electrode can be inserted through a multipiece cannula supported by an instrument holder of a surgical arm. The surgical arm can be positioned such that a distance from the target to the proximal end of the cannula is equal to the length. The electrode can be fed through the cannula and through the anchor bolt into the cranial cavity. Feeding of the electrode through the cannula and into the cranial cavity can be stopped when the length of the electrode fed into the cavity reaches the length between the proximal opening of the multipiece cannula and the target.

Medical intervention instrument

A grasping forceps 1 includes: a pair of guide sections 7A and 7B that guide maneuvering wires 6A and 6B in a direction of an axial line C of a sheath; an extending-and-retracting member (transmission section) 8 that transmits displacement information of the maneuvering section to the maneuvering wires 6A and 6B and outputs the displacement information to the intervention instrument; a distal direction movement inhibitor section (specific directional movement-inhibitor section) 10 that allows the sheaths of the maneuvering wires 6A and 6B toward the distal end; a proximal direction movement inhibitor section (specific directional movement-inhibitor section) 11 that allows the sheaths of the maneuvering wires 6A and 6B toward the distal end; and an locked-state-releasing section 12 that releases an engaging state of the guide sections 7A and 7B with the distal direction movement inhibitor section 10 or the proximal direction movement inhibitor section 11 based on the displacement input by the maneuvering section. Accordingly, an medical intervention instrument can be provided that can maintain a certain attitude of the intervention instrument once established during intervention even if an external force is applied, and that can carry out identical operations simultaneously, i.e., manipulating of the intervention instrument and releasing of a certain attitude of the intervention instrument.
