A surgical implant (10) comprising an implant body (12) and a bone interface layer (18). The implant body comprises a polymer material and has a bone-facing surface (14). The bone interface layer is provided over at least a portion of the bone-facing surface. The bone interface layer is formed of a material having a higher stiffness than the polymer material. The bone interface layer includes a polymer barrier layer (40) at least 0.5 mm thick across a majority of the surface area of the bone interface layer, the polymer barrier layer being impermeable to the polymer material. A method of manufacturing the surgical implant comprises over moulding the polymer material over the bone interface layer to form the implant body.

Provided is a surface treatment method for a surgical implant that improves fatigue strength of the surgical implant while maintaining the microscopic surface structure of the surgical implant. A surface treatment method for a surgical implant, including: placing an additive manufactured surgical implant in a processing liquid, the surgical implant including a microscopic surface structure having a complete penetration area and an incomplete penetration area; and causing a nozzle immersed in the processing liquid to eject a cavitation jet of the processing liquid to the surgical implant to remove the incomplete penetration area remaining on a surface of the surgical implant and apply a compressive residual stress to the surface of the surgical implant.

A device for manipulating an orthopedic implant includes a base graspable by a user, a bending assembly including a pin having an outer surface extending between a first end of the pin that is coupled to the base and an opposing second end of the pin, and a gripper coupled to the outer surface of the pin and including a jaw, and a slider coupled to the bending assembly and slidable relative to the bending assembly to shift the jaw of the gripper between a flexed state for gripping an orthopedic implant and an unflexed state for releasing the orthopedic implant.

The present disclosure relates to a method and system for displaying an image of an anatomical structure generated during a surgical procedure. The method includes: segmenting at least one vertebral body from at least one image in a first three-dimensional image dataset. The method includes: receiving at least one image in a second three-dimensional image dataset. The method includes the steps of: registering the segmented at least one vertebral body from the at least one image in the first three-dimensional image dataset with the at least one image in the second three-dimensional image dataset. The method includes: determining the position of the at least one surgical implant based on the at least one image in the second three-dimensional image dataset and a three-dimensional geometric model of the at least one surgical implant. The method includes: overlaying a virtual representation of the at least one surgical implant on the registered and segmented at least one vertebral body from the at least one image in the first three-dimensional image dataset.

A nanocomposite derived from organic sources, including waste date seeds, pomegranate peels and camel knee bone. The nanocomposites can be used for the synthesis of surgical implants, are biodegradable, and do not require surgery for their removal. The nanocomposites contain nanoparticles of date seeds, pomegranate peels, camel knee bone, polymers, organic substances, and organic dyes. A method for the preparation of the nanocomposites includes molding the nanocomposites into organic bone screws, bone plates, and dental prosthetics.

The invention relates to a device for assisting the attachment after placement of a surgical implant, i.e. An interbody fusion cage, in particular a fusion cage for a zygopophyseal joint, in which the implant (2) is intended to be inserted into a bone cavity, through the bone tissue before reaching the implant (2) and into a hole (20) therein, by at least one screw or the like, the invention relates to a device (1) for fixing an implant (2) in a bone cavity, then screwed into bone tissue, comprising: a combination of means (31) for holding the implant (2) designed to be able to hold the implant (2) when the implant is arranged in the bone cavity, and drilling guide means (42), the drilling guide means (42) being connected to the implant (2) by means of configurable connection means (40, 40 '). 41) is fixedly connected to the retaining means (31) such that the drilling axis (X) is aligned with the hole (20).

The utility model discloses steam sterilization equipment for dental implants, which relates to the technical field of surgical implants and comprises a sterilization device, a sterilization bin is arranged on one side in the sterilization device, guide rails are fixedly connected to the inner walls of the two sides of the sterilization bin, a tray with a hole is slidably sleeved in the guide rails, and the tray with the hole is connected with the sterilization bin. Sliding rods are fixedly connected to the four corners of the upper end face of the sterilization bin, jacking plates are slidably connected to the sliding rods in a sleeving mode, a plurality of supporting cylinders are fixedly connected to the upper ends of the jacking plates, supporting shafts are slidably connected to the supporting cylinders in a sleeving mode, and contacts are fixedly connected to the upper ends of the supporting shafts; by arranging the tray with holes, the jacking plate, the supporting cylinder, the supporting pad, the supporting shaft, the supporting spring, the lead screw, the sliding block and the connecting plate, the effect of more comprehensive sterilization is achieved, the problem that sterilization dead angles exist due to the fact that a traditional implant and the tray have a contact surface is solved, and practicability is achieved.

An apparatus for eye surgery may include an implant support, a folding arm (330), an edge roller (335), and a dial (320). Some embodiments of the implant support may include an implant bay, a tab rail, a tab slot, and a pawl. The folding arm may be coupled to the implant support and may include a dial pin. The edge roller may be coupled to the implant support and may include a roller track. Some embodiments of the dial may include an arm track, a roller pin, a plurality of ratchet teeth, and a tab. The dial can be configured to be rotated relative to the implant support so that the ratchet teeth rotate relative to the pawl, the dial pin travels the arm track and causes the folding arm to rotate, and the roller pin then travels the roller track to cause the edge roller to rotate.
