Systems and methods for intraoperatively measuring anatomical orientation
Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.
Adhesion-preventing composition
[Problem] An adhesion-preventing material having a high adhesion-preventing effect has been demanded. [Solution] An adhesion-preventing material including a sterilized biocompatible sponge-like laminate, wherein the sponge-like laminate comprises a sponge-like first layer and a sponge-like second layer each of which is at least partially crosslinked with a curing agent and comprises a low-endotoxin alginic acid monovalent metal salt, the alginic acid monovalent metal salt in the first layer has a weight average molecular weight of 10,000 to 2,000,000, the alginic acid monovalent metal salt in the second layer has a weight average molecular weight of 1,000 to 1,000,000, the weight average molecular weights are measured by a GPC-MALS method after a decrosslinking treatment, and the weight average molecular weight of the alginic acid monovalent metal salt in the first layer is higher than that in the second layer.
Surgical stapling apparatus with firing lockout assembly
A surgical stapling apparatus includes a loading unit having first and second jaw members, a drive beam, and a firing lockout assembly. The drive beam is axially movable within the loading unit during a firing sequence. The firing sequence includes an advancement stroke which moves the first and second jaw members to an approximated position and a retraction stroke which moves the first and second jaw members to an unapproximated position. The firing lockout assembly includes an iterating plate, a capture gear, and a lockout pin. The iterating plate is disposed adjacent to the drive beam and is incrementally movable proximally within the loading unit during the firing sequence. The capture gear is rotatable between first and second positions during the firing sequence and is configured to move the iterating plate. The lockout pin is configured to lock the drive beam after a pre-determined number of firing sequences.
A STORING DEVICE AND A SYSTEM FOR TRACKING ABSORPTION PRODUCTS
The invention is referring to a storing device and a system for tracking absorption products and their use, which comprises said storing device and a verification device for tracking the use of absorption products in terms of their number and time of use, and which alerts the user about the status of the storing device and of potentially hazardous use of the absorption products.
INSERT ASSEMBLY WITH RADIOFREQUENCY IDENTIFIER FOR MEDICAL DEVICE
An insert assembly, insertable in a handpiece of a medical device, has an insert having an insert metal tang, a ferromagnetic layer in contact with the insert metal tang, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer, having an insert antenna metal element and configured to receive and transmit electromagnetic fields, and an identification chip operatively connected to the insert antenna and configured to transmit information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of an electromagnetic field caused by parasitic effects due to interaction of a transmitted or received electromagnetic field with metal parts of the insert metal tang, liquids present in the insert, and the insert antenna metal element. The ferromagnetic layer dielectric layer and insert antenna form a transceiver device putting the identification chip in communication with a handpiece antenna.
PRIMING INSTRUMENT FOR MEDICAL DEVICE, MEDICAL DEVICE SYSTEM, AND METHOD FOR PRIMING MEDICAL DEVICE
A priming instrument for a medical device, a medical device system, and a method for priming a medical device, which are capable of priming the medical device having a plurality of lumens that open in a living body. The medical device includes a liquid delivering lumen having a first opening portion and a discharge lumen having a second opening portion. The priming instrument includes an instrument body having a hollow portion that covers the first opening portion and the second opening portion of the medical device, the hollow portion includes a distal portion and a proximal portion, the distal portion of the hollow portion is closed, the proximal portion of the hollow portion has an insertion port into which the medical device is insertable, and the insertion port includes a sealing portion that seals an inside of the hollow portion when the medical device is inserted into the hollow portion.
TIP PROTECTOR FOR A SURGICAL INSTRUMENT, ASSEMBLY AND METHOD
A tip protector, for a surgical instrument having a shaft and an instrument tip near a distal portion of the shaft, includes a tip housing for releasably receiving the instrument tip; a clamp system suitable for gripping a portion of the surgical instrument to position the tip protector; and a distal through opening at or near the distal end of the tip housing. The distal through opening has an opening size that is adjustable.
Bone-anchoring device for a pedicle access
A bone anchoring device for anchoring and fixing vertebrae and for insertion into a pedicle canal is disclosed. A fork head having a U-shaped cut-out in a side view for a correction element, a connecting rod with two legs which terminate proximally and form a threaded section which engages with an adjusting means, wherein the legs have a radially outer circumferential area in which at least one retaining groove or other instrument attachment point is formed for gripping the fork head by a handling instrument, and a bone anchoring element with a proximal end facing away therefrom in the axial direction such that a distal direction and a proximal direction are also defined. The bone anchoring element has a spherical head at the proximal area, and the bone anchoring element is polyaxially pivotable with respect to the fork head, and has a pressure piece distally partially surrounds the bone anchoring element at the ball head, and proximally forms a seat for the connecting rod.
Mixed-reality surgical system with physical markers for registration of virtual models
An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
BARRIER DISPENSER AND METHOD OF USING THE SAME
Apparatus and methods for applying a barrier to a medical scope are provided. An apparatus may comprise a source of film and a housing. The housing may comprise a chamber configured to support therein the source of film, and an opening provided through a wall of the housing to permit a portion of the film to extend out of the chamber when the film is dispensed. The housing may comprise a recess located such that the extended portion of the film is permitted to hang freely in proximity to the recess. The recess may be sized to receive a distal portion of the medical scope. The recess may be adapted to allow the extended portion of the film to be applied to the distal portion of the medical scope when the distal portion is placed into the recess with the portion of the film located therebetween.
