The hip joint using 3D for peace

Kycelní kloub s pomocí 3D na míru - January 10, 2017

Translated segments:

Kladenska Beznoska company is a purely Czech family-owned company engaged in the development and production of instruments and implants for traumatology and orthopedics. It was founded in 1992 with the privatization operation Surgery former Poldi Kladno and followed it for more than twenty years of experience whose history began as early as 1969. Today, the firm generated turnover amounting to one hundred and fifty million a year, and in the Czech Republic occupies an important position in the production joint replacements. Its products are currently exported to nineteen countries, with thanks to former ties focused on markets in Central and Eastern Europe, the Middle East and the newly established close contacts with distributors from Portugal. It has several patents and recognized awards.

Processing computer-aided design, prototype production and subsequent then the fi sional layman product can be characterized as follows: 1. Using a computerized tomography (CT) data are obtained, which accurately describe the current status of the patient. 2. Such information, divided into roughly three hundred cuts, designer loads the appropriate applications with which each of the cuts manually define bone tissue. 3. The result is a computer model of the pelvis, which is still smooth surface and then is ready for processing on the 3D printer. 4. In the 3D printer is creating a plastic model of the current state of the basin of ABS plastic material, which serves to preoperative preparation. His gradual construction of the printer takes about seventy hours. 5. After printing, the plastic model of pan-fabricated temporary deprived of aid, dried and sent to the treating team of doctors who are on the mark the area of ??resection. 6. Computer model of the basin is loaded into Pro / Engineer, where the designer is adjusted according to the assignment of physicians, ie. "Cut" into it planned resection resection based on the designated physician and suggests the shape of a metal implant. 7. When the computer design of the implant mutually agreed, will use the resulting data outside contractor to create a metallic implant, which creates 3D printing method EBM (Electron Beam Melting). 8. Now - already in the form of a physical prototype - ABS plastic model pans trimmed according implied resection and the resulting space compared with the fi nal product implant. If everything is in order, the implant sends doctors who will prepare the appropriate surgical procedure and make appropriate patient treatment. Despite high knowledge-used applications, and more than a decade of experience with Pro / Engineer, evaluated processing tasks such Ing. Milan Sekerka very complicated. It should advance to anticipate changes shape, resulting from consultations with doctors, and thus compose a tree forming commands. Pro / Engineer it still relishes - complex shape geometry cope without problems, and the system helps us greatly in dealing with changes in the structure of the implant, which are based on consultations. The emergence of the draft and final solution to the implant design engineer working with the client on the one hand, a medical team treating the patient, and specialists in orthopedics with years of clinical experience. Consultant is also important external supplier of the implant, creating the 3D printing of titanium alloy. Challenging joint replacements that arise in the development team at Beznoska, are intended mainly for oncology ill patients with irreversible damage to the bone structures. The implant replaces only the removal of bone tissue, but also allows the implant prosthetic replacement of the entire joint.
