A range of Leica Ophthalmology microscope compatible adapters has been developed to enhance ergonomics during surgical procedures. These adapters are specifically designed for use with microscopes that have "short" heads. To achieve a neutral positioning of the surgeon's head and neck, it is recommended to use tiltable binoculars in conjunction with these adapters. The adapters are available in various sizes, ranging from 10cm to 20cm at intervals in this segmented version. Whole-body versions of 5cm and 7,5 cm are available.
To facilitate customization and testing, it is suggested that certain 3D parts be printed using a local 3D printing service with the whole-body version of this part. This allows surgeons to evaluate different sizes and select the most suitable adapter for their specific surgical environment. However, it is important to note that these 3D printed parts should not be used for extended periods as they may become fragile and pose risks to both patients and staff.
Once the ideal-sized adapter has been identified, it is advisable for surgeons to have the corresponding part manufactured in metal by a local locksmith, using aluminum as the preferred material. This ensures durability and long-term safety during usage. The segment version of the adapter is intended for metal part creation. The 3 parts will have to be assembled using screws before use. Intermediate parts of various sizes are interchangeable and upper and lower parts are always used in the segmented version.
It is worth mentioning that sizes of 5cm and 7,5cm are available exclusively in the whole-body versions. If the ideal size exceeds 10.0cm, it is recommended to utilize the segmented version of the Leica adapter for the creation of the metal part. This is to prevent excessive weight, which could potentially compromise the stability of the microscope's counterweight and hinder proper positioning of the microscope's head.
Intermediate part sizes refer to the final length of the assembled part.
One downside of using these adapters is that they reduce the visual field by around 20 to 40%. However, this is not a major issue when it comes to anterior segment surgery, as it is relatively easy to adjust to.
The development of these adapters aims to assist surgeons in achieving improved ergonomics during their daily use of microscopes. It is important to note that these adapters are intended for non-commercial purposes only and do not infringe upon any copyrights held by microscope manufacturers.
Two types of files are provided for the adapters, with the "stl" extension intended for 3D part creation and the "stp" extension intended for the creation of metal parts.
I have tested and used these adapters in my surgeries in more than 3,000 cases and no other issues were observed. Enjoy, and take care of your health!
