Justtach ASM 2

Background:

We have been doing Endoscopic ear surgeries since 2013. After developing and using Justtach for three years we realised that there were certain concerns related to its functions. The main concern of Justtach is that it could interfere with the long axis working distance during drilling. Hence in 2016, we modified Justtach so as to incorporate the rotating handle into it and made it more user friendly.

Need for invention:

The objective of the modification is to overcome the difficulties encountered with the first generation of endoscope holder, Justtach and to add more features [11]. With inclusion of new features, the comfort and ease of the technique has increased tremendously.

Technical description (figure 15,16):

It has two parts:

The main body
The rotatable handle

The main body is rectangular in shape and measures 130 x 80 x 10 mm in dimensions with a square slot is 110mm x 60mm x10mm for gripping onto the microscope with a tightening screw. The rotatable handle is thinner and measures 120 x 10 mm with a circular slot measuring 16mmx16 mm in diameter. It is connected to the main body with a screw for tightening action. The advantage of the rotatable handle is that it can be fixed in any angle (away from the working long axis of the microscope) convenient to the surgeon so that the operating space is away from the axis of the microscope. Hence it is more beneficial in endoscopic ear surgery with drilling, where during mastoidectomies, the shaft of the drill could previously interfere with the body of Justtach. There is a protector sheath for the endoscope provided along with it.
