A minimally invasive, fluoroscopically guided system is disclosed for stabilizing the articular facet joints of adjacent vertebrae. Ring and dowel implants are disclosed for installation into the facet joint. The invention includes a novel spine surgical training aid used in the initial surgeon training process for refreshing the surgeon's perspective of the critical three dimensional anatomy of the vertebrae. The invention also includes a surgical kit having a range of size-specific drills, inserters, impactors and custom-length long k-wires matched to the internal diameter of the instrumentation system.

A kit management system for use in microsurgery is disclosed. The kit management system includes a plurality of tubing, surgical instruments, connectors, an instrument tray, a connector tray, and a tubing organizer. A tubing organizer for removably receiving and holding a plurality of tubing in a spaced relationship during microsurgery is also disclosed.

This system is composed by mechanical telemanipulators, with master-slave configurations, working together with suitable solutions for image acquisition and display, which are able to transmit, with optional magnification, images from the surgical area to the surgeon. Therefore, the surgeon's capacities and comfort are increased by enhancing the surgeon's motor and visual skills as well as the ergonomics while doing different surgical tasks through access incisions on the patient body. Aside from offering improved performance during procedures involving microsurgical techniques, this system also brings safety, intuitiveness, and cost-effectiveness advantages over current alternatives. Due to the compatibility with current visualization systems for microsurgery, together with the light weight and the compact configuration of the mechanical telemanipulator, this surgical system can be very easily brought to and removed from the surgical area, which enables its intermittent use on several surgical procedures requiring microsurgical techniques. Therefore, it does not require drastic changes in the workflow and setup of current operating rooms and can be more easily adopted by several surgical teams.

In order to develop an electric probe for microsurgery, which is provided in particular in ophthalmology for intraocular treatments of the eye, in such a way that the probe is constructed in a simple manner, can be produced inexpensively, is easy and safe to handle, and at the same time can be used for multiple functions as an illuminated intraocular probe, it is suggested that the electric probe comprises an outer electrode, an inner electrode and a light guide. The inner electrode has a contoured electrode end face and projects out over a front end of the light guide or is embedded in the light guide so as to terminate with it. When the electrodes and light guide are constructed cylindrically, the hollow space remaining between the electrodes and the light guide is provided as a suction channel for sucking out tissue particles, and in various embodiment forms, including an embodiment as an illuminating endoprobe, the electric probe is connected to an operating and controlling device by which pre.-defined, changeable parameter sets which are adapted depending on the probe characteristics can be adjusted and retrieved.

The transplanted cornea attachment method in eye microsurgery and the implant for attaching transplanted corneas, both donor and artificial, without the use of sutures consisting in the cutting of a fragment of the donor tissue (2) and, subsequently, the incision of the corresponding fragment (1) in the recipient tissue (3) so that the donated fragment (2) and the recipient incision (1) have teeth that interlock with each other, and the circular incision (5) in the stroma of the donor and recipient corneal stroma which is less in diameter in the donor tissue and more in diameter in the recipient tissue wherein the fastening implant (4) is subsequently inserted.

A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye.
