  • Patent number: 11096681
    Abstract: An all-suture suture anchor system includes an all-suture anchor, an inserter, and a specially designed drill. The drill is used to enlarge the hole and create a pocket under the bone surface from the pre-drilled hole. The created pocket is intended to accommodate the expansion of the anchor when deployed into the bone, generating a true mechanical interference under the bone surface. The anchor is loaded on the inserter and placed at full length vertically inside the drilled hole. While holding the inserter on top of the drilled hole, so that a feature on the inserter keeps the anchor to a desired depth below the bone surface, tension is applied to the suture limb that is connected to the bottom end of the anchor. This tensioning step causes the length of the anchor to contract vertically and the anchor is simultaneously expanded circumferentially to fill the pocket previously created by the drill.

  • Patent number: 11019241
    Abstract: Methods and apparatus are disclosed for selecting a lens control mode for a camera in external magnetic fields or other types of non-magnetic interference. In embodiments, when the camera is activated, a test of a position sensor for the camera lens is performed by moving the camera lens through a range of positions and collecting values from the sensor. In embodiments, the sensor readings are analyzed to determine conditions such as (a) whether the sensor is saturated by an external magnetic field or non-magnetic interference, (b) whether the sensor's readings are within an error margin, and (c) whether a computed position offset for the sensor is valid. Based on the analysis, the camera is placed into a first control mode where movement of the lens is controlled using the position sensor, or a second control mode where lens movement is controlled without the position sensor.

    Abstract: A medical or dental device for determining a bone's quality by cutting a thread into the bone with a rotating threaded element comprises a control unit having a measurement circuit configured: (i) to determine values of the motor current via a first electrical contact device with which the motor drive is supplied for rotational drive of the threaded element that can be connected to the motor drive, the current values being a measure of the bone's quality; (ii) to monitor and/or to determine the penetration depth of the threaded element into the bone, and (iii) to generate measurement signals which show the relationship between the penetration depth and the determined current values or parameters derived therefrom, and to transmit these signals to a display unit, which displays the relationship between the determined current values or parameters derived therefrom, in particular the bone's quality, and the penetration depth.

  • Patent number: 10966703
    Abstract: A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.

  • Patent number: 10952752
    Abstract: A posterior cervical fixation system includes a facet lock comprising an elongate member having distal and proximal ends. A tapered wedge projects axially from the distal end and defines a wedge axis, the wedge being sized and configured for insertion into a facet joint of a cervical spine. The facet lock includes opposing first and second dovetail recesses. The system further includes a tubular guide having distal and proximal ends and a lumen extending therethrough along a central axis. The tubular guide has a plurality of dovetail projections extending exteriorly outwardly, each dovetail projection terminating in an engagement surface that is spaced respectively at a different radial distance from the central axis. Each dovetail projection is configured for individual releasable attachment to one of the facet lock first or second dovetail recesses to selectively space the wedge axis and the central axis at different distances for lateral mass screw placement.

  • Patent number: 10869686
    Abstract: A surgical method utilizes a cutting blade having a thickness along a cutting edge of between about 0.0005 inch and about 0.020 inch and preferably between about 0.001 inch and 0.010 inch. The blade is moved in contact with relatively hardly tissues which are disposed adjacent to softer tissues at a surgical site in a patient. The blade is ultrasonically vibrated during the moving of the blades, whereby the hard tissue is cut with a modicum of damage being inflicted on the soft tissue.

A proximal end of the first broach comprises a first base having a first maximum area. The body portion can be releasably coupled to the proximal end of the first broach so as to define a first offset between a medial end of the neck portion and a longitudinal axis of the first broach, or releasably coupled to the proximal end of the second broach so as to define a second offset between the medial end of the neck portion and a longitudinal axis of the second broach. The first offset is smaller than the second offset.

  • Patent number: 10835264
    Abstract: A drill guide includes a body, a stabilizing member, a tubular guide sleeve, and an engagement member. The body includes a first channel aligned with a longitudinal axis and a second channel transverse to the longitudinal axis. The first channel is dimensioned to receive the sleeve, while the second channel is dimensioned to receive an engagement member. The engagement member is adapted to move within the second channel between an engaged position, where the engagement member inhibits proximal motion of the sleeve, and a second position, where motion of the sleeve is not inhibited. An alignment member is further mounted to the distal end of the sleeve that includes a distally extending member, spaced from the sleeve. In use, the distally extending member may be employed to exert a force upon a bone or other tissue lateral to the longitudinal axis for improved positioning of the bone or tissue.

  • Patent number: 10820914
    Abstract: A method for automated opening of craniotomies includes, under the control of a computer processor, drilling into a skull for a predetermined distance and determining when there is a conductance drop near the drilling tip that indicates skull breakthrough. If the conductance is not below a predetermined threshold, drilling continues iteratively manner until conductance is below the threshold. A craniotomy pattern may be predetermined and automatically drilled under control of the processor. A cranial window may be created by drilling along a path that interpolates between holes to form the circumference of the window. An automated craniotomy opening apparatus includes a drilling apparatus with a drilling tip, at least one drilling apparatus positioning device, a detection device, and a computer processor that controls the drilling apparatus, the positioning device, and the detection device according to the method. Determining conductance may include use of an impedance detection circuit.
