4 Planning Manual for the Leica OHC4 / Leica OHC5 Ceiling Mount

About this Planning ManualThe Manual before you answers questions related to plan-ning for the ceiling mount Leica OHC4 and Leica OHC5 from Leica Microsystems. With a weight of 500 kg and a boom radius of 1.43 m, it places particular requirements on the room planning and structural engineering. The following pages help all involved with the necessary clarifications: hospital technicians, architects, structural engineers, and electricians find here all the information and technical re-quirements necessary for a successful installation.

In addition to the structural requirements, personal pref-erences should also be taken into account. Each operat-ing room is shaped by the way its staff works. Therefore you will also find draft proposals in this Manual that help you find the optimum location for your Leica OHC4 / Leica OHC5.

But even the best manual is no substitute for personal sup-port. If at any time questions arise that are not answered in this Planning Manual, please get in touch with your con-tact person at Leica Microsystems directly. You can find all contact information on page 6.

We wish you success!

Product Information


About this sectionThis section helps with checking the structural require-ments. The load capacity of the ceiling plays just as much of a role here as the available space or the kind of opera-tions that are performed.

If the operating room does not meet one of the requirements, it does not mean that the installa-tion is impossible – it simply means that additional clarifications must be made. Most problems can be solved by adapting standard components.

What happens after the clarification?Every operating room is unique, and the responsible sur-geon knows exactly what is important to him or her. There-fore send the completed checklists and data sheets by fax or e-mail to your contact person at Leica Microsystems. He or she will closely examine the state of affairs and discuss with you how to proceed.

Your benefits Ϙ You and your customer know with certainty whether

the project can be implemented

Ϙ In the case of special requirements, the necessary actions can be initiated at an early stage

Ϙ There will be no project interruptions caused by the need for subsequent clarifications or improvements

Radius of action

This is a recommended standard positioning. In each case, however, the surgeon must check that proper work is ensured in this position. (Taking into consideration the patient's position, the kind of operation, operating room table, operating room lamps and the position of the assistants and nurses. Also particularly critical is the use with MRI systems.)

This is also the range of movement of the arms and weights of the ceiling mount. Ideally, there should not be any secondary devices in this range. A part of the range can be protected from collisions by rotation stops on the ceiling mount. This “dead” range can be freely selected via two stops (minimum 90°).

Work is not allowed without a rotation stop, since otherwise the cables are in danger.

Overview of the Control Unit locationand the cabling of the system:

The Leica OHC system requires installation of the control unit in the wall. For this reason, an opening of exactly 340×730 mm must be created with a mounting hole pattern in accordance with the drawing next to this paragraph. The depth must be at least 300 mm.

The transformer is placed on the base, which requires a height of the CU opening of at least 600 mm .

All cables needed for the system operation, incl. Leica FL400 / Leica FL800, are provided along with the Leica OHC. The cables are 20 m long. If the distance from the CU to the stand is longer than 20 m, Leica Microsystems must be notifi ed (see contact information on page 6).

The standard cables are long enough if the stand control unit and the documentation system (Leica MDRS, HDMD) are located at the same place. Some cables are too short for other placements. In this case, contact Leica Microsystems (see page 6).

Questions for the Surgeon


About this sectionThe Leica ceiling mount OHC serves one purpose only: It should make work as easy and comfortable as possible for the surgeon. Every doctor has his or her way of operating, with a unique style and an arrangement that is best suited to him or her.

For these reasons, it is of great importance that the doc-tor's needs and desires be taken into consideration during the planning. Where is the illumination located? The anes-thesiologist? The assistant? Even the difference between left and right-handedness can be significant.

Unlike most other fixtures, the position of the Leica OHC cannot be changed again. The better the setup is planned, the more pleasant it will be to work with the ceiling mount.

Every question has its purposeThis section poses various questions that are important for the planning and setup. Please read through these ques-tions carefully. In the column on the right, you also find a short explanation of why these questions are significant.

These responses provide an important foundation so that your Leica system can fulfill the most stringent require-ments later as well.


General questions

Question Explanation

What kind of operations is the Leica OHC4 used for? The response helps determine the optimum positioning. In any case, it must be established that the operating fi eld lies within the range of the Leica OHC and that the operating room illumination is not cast in a shadow.

Is the operating room table moveable?■ Yes ■ No

A moveable table grants more freedom for different procedures and is very advantageous in any case.

Is the operating room table fi xed on a base?■ Yes ■ No

A base limits the table's movability or even prevents movement entirely. This requires exact consideration of all possible procedures. In addi-tion, it must be judged whether the combination of the Leica OHC and the position of the operating room lamps enable these procedures.

In what range is the operating room table moveable? From which direction will the surgeon operate?

Example

90°

The operating room lamps cannot be oriented to-wards the operation area from the side of the Leica OHC, since otherwise collisions with the Leica OHC may result. Therefore lateral procedures on the skull with operating room illumination are not pos-sible on the side of the Leica OHC.

Specifications for the Structural Engineer


Vibrations in general

Vibrations of the microscope itself are absorbed by the damping material between ceiling mount and horizontal arm. Vibrations of the ceiling are reduced, because the ceiling mount does have a patented damping system for vibrations in the range of 10 – 60 Hz. The microscope allows a verti-cal amplitude of less than 0.4 mm (peak to peak value) for all used working distances and the whole zoom range with eyepiece 10×.

Ϙ Extrapolated to a vibration of the ceiling, the amplitude of the ceiling related to the floor must be smaller than ±1 mm.

Ϙ Short wavelengths are worst, longer wavelengths of a few seconds duration will reduce the perceptible effect.

Ϙ For better efficiency and reduced costs we recom-mend to absorb vibrations directly at their source (compressors, elevator machines, etc.).

�

amplitude x = max. 1 mm

wavelength

Vibration absorber

The vibration absorber is used for maximum stabi-lization of the microscope. Reducing the vibrations ensures a stable, clear image.

Only vertical vibrations are absorbed, not lateral vibrations.


General questions

Question Explanation

Is the facility in question a new construction or an existing operating room?■New ■ Modification

For a modification, a special solution may need to be found in some cases.

Is the operating room located near the helicopter landing site?■Yes ■ No

Additional vibrations occur in the vicinity of the helicopter landing site, which must be reduced by additional measures, or they could poten-tially hinder use of a ceiling mount.

Is the clinic located by a heavily traveled road with heavy goods traffic?■Yes ■ No

Additional vibrations can occur in the vicinity of such streets, which must be reduced by additional measures, or they could potentially hinder use of a ceiling mount.

Are there any sources of vibration in the immediate vicinity of the mounting point or directly above it? (For example, an elevator, compres-sors, walkways or drivable passageways.)■Yes ■ No

Additional disruptive vibrations can occur in the vicinity of such sources of emissions, which must be reduced by additional measures, or they could potentially hinder use of a ceiling mount.

Are there any elements already present that must be taken into consideration? This would include, for example, ventilation equipment, electrical equipment, etc.■Yes ■ No

If unobstructed positioning of the stand cannot be ensured due to exist-ing fixtures, other clarifications must be made first.

Does the operating room in question have a concrete or steel con-struction?■Concrete ■ Steel

With a concrete construction, a standard solution is possible in most cases. A steel construction requires a custom solution (see the sketch “Basics of calculation for the ceiling plate construction”).

Basics of calculation for the ceiling plate construction

With steel constructions, it is particularly important that sufficient rigidity is achieved in order to prevent vibrations and residual shaking. The solution proposal above has been tried in practice and provides for a reliable, vibration-free mount.

Planning Aids for the Architect


Planning aid

Collisions with other fixtures are a high risk. Since Leica Microsystems does not know the local condi-tions, we cannot assume any responsibility.

To minimize the risks, however, the existing 3D data of the hospital can be

Ϙ supplemented with the stand data,

Ϙ prepared

Ϙ and checked for possible collisions by Leica Microsystems.

Usable formats are DXF and DWG files. The costs for integration into the existing 3D plans amount to approx. 1000.00 Swiss francs per 3D plan.

This cost estimate refers to typical data integration. If additional expenses arise from special require-ments, then an individual quotation will be created.
