Described herein are examples of orthopedic reamer heads for preparing a bone to receive an implant, as well as methods of assembling reamer heads. An illustrative example of a modular reamer head can include a body and a cutting system. The body can include a generally dome shape having an outer surface extending from an apex region to a base. The outer surface can have a recess including one or more arcuate channels that extend from the apex region towards the base of the dome. The cutting system can have one or more arcuate elements having cutting elements. One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.

The present application provides an endoscopic device having at least one shaft, which has at least one portion deflectable in at least one plane, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member. The first connection member is formed at least partially from a first material, and the second connection member is formed at least partially from a second material, of which the elasticity differs from that of the first material.

A reamer head assembly comprising: a base member supporting a reaming member, the reaming member comprising a reaming member configured to ream bone; wherein the reaming head assembly comprises a plurality of recesses arranged about the reaming surface, the plurality of recesses configured to allow manual gripping of the reaming head assembly.

A medical instrument and a semi-finished instrument. The semi-finished instrument includes an instrument body part blank for forming an instrument body part of the medical instrument. The instrument body part blank is made of a metal, in particular an instrument steel. The semi-finished instrument also includes a distal end region and a recess on the distal end region for accommodating a hard metal element. The recess has an abutment face for the hard metal element. The instrument body part blank includes a solder chamber for accommodating solder. The solder chamber is fluidically connected to the recess.

The invention relates to a novel multivalent atrial appendage occluder of hybrid design based on two different atrial appendage occluders, one having a proximal disk-shaped cover and a second version without a proximal cover. The two occluder variants each provide relevant application solutions by themselves. The invention further relates to multiple specified, universal devices composed of predominantly rotationally symmetrical individual parts for producing these different LAA occluders (LAA=Left Atrial Appendage) which are graded in different sizes, for the interventional, catheter-based closure of the left atrial appendage. Axially and radially oriented hooks support the secure and gentle anchoring of the occluders 1 in the retaining area of the atrial appendage 26. As a result, the use of substantially smaller access ports in the interventional application is possible. The two atrial appendage occluder variants, with and without proximal cover 14, can be inserted using the same controllable access port and can be implanted in various sizes individually or in combination with one another and likewise as a hybrid variant of two occluders, one without a proximal cover (14) and one subsequently with a proximal cover (14) in one and the same atrial appendage (24) as shown in FIG. 17. The two atrial appendage occluder variants can each be released during the implantation phase in three stages until they are fully unfolded.

Systems and methods are provided to plan a spinal correction surgery. The method includes measuring parameters of a spine in a two-dimensional (2D) spinal image including a thoracic Cobb angle and a thoracic kyphosis (TK) and transforming the 2D image to a three-dimensional (3D), spinal image representation. The transforming includes performing segmentation of spine elements in the 2D image, and applying a formula based on the thoracic Cobb angle and the TK to the spine elements. The method includes identifying a TK goal having a post-operative TK value to selected spine elements, transforming a gap of the spine elements representative of a difference between the pre-operative TK in 3D spinal image representation and the TK goal to create a 3D post-operative spinal image representation, and determining a first rod design based on the 3D post-operative spinal image representation to achieve the post-operative TK value in the spine elements.

A computer system receives readings from sensors embedded in a spinal implant implanted in a patient during surgery. The sensor readings are indicative of a load applied by a spine of the patient on the spinal implant. The load causes physical discomfort to the patient. A feature vector is extracted from the implant sensor readings using a machine learning module. The feature vector is indicative of the physical discomfort caused by the load. Electrical signals are generated using the machine learning module based on the feature vector. The machine learning module is trained based on patient data sets to generate the electrical signals to balance the load, such that the physical discomfort is reduced. The electrical signals are transmitted to one or more actuators embedded in the spinal implant to cause the one or more actuators to configure the spinal implant, such that the load is balanced.

A spinal surgery retractor and method of use. The retractor includes a slotted keyway for integrating a keyed spinal distractor. The retractor and distractor combination slide together to displace a portion of the intervertebral disk space to restore or maintain intervertebral spacing and facilitate retraction of surrounding soft tissues while disk space surgery is performed. The distractor head and mating portion of the retractors have matching profiles that enable the retractor to maintain distraction of the vertebra after removal of the distractor portion of the tool, permitting access to increase at the operating site.

A hybrid radiolucent screw having radiopaque components and radiolucent components, which collaboratively define a tip of the screw and a head of the screw. In this manner, distortion is minimized during fluoroscopy or radiography of the screw while visualization of the screw and surrounding area is enhanced.

An apparatus including a basket device including a basket section; and a sheath on the basket device. The basket device and the sheath are configured to longitudinally slide relative to each other. The basket section includes at least two groups of loop petals including a first group having at least two first loop petals and a second group having at least two second loop petals, where the first loop petals have a different size than the second loop petals.
