Hydraulic operating table: energy supply for height adjustment in confined spaces

Energy chain, drum and guide trough in operating table solve space and reliability problems.

This mobile operating table is hydraulically operated. Data and electrical cables as well as hydraulic hoses are routed along the column to control and feed the reclining surface. Due to the great height adjustment, they must be reliably guided in the smallest of spaces. After the igus e-chains of the E2/micro product range initially excelled in guiding the electrical cables, the hoses are now also guided in several predefined radii. A guide plate prevents the e-chains from getting caught on the side of the column.

Profile

What was needed: Energy chain for the guidance of electric cables and hydraulic hoses
Requirements: Small installation space, swerving and tilting of the first energy supply solution in the column of the table due to the high drive forces
Industry: Medical technology
Success for the customer: The energy chain E2 micro with several predefined radii proves to be a reliable and trouble-free system in the mobile operating table

Surgical table

Problem

This mobile operating table from Schaerer Mayfield can be adjusted in height as required and is hydraulically operated. A Can-Bus cable and hydraulic cables are guided along the column to control system and power the lying surface. Due to the extreme height adjustment of the column, these must be reliably guided in a very small space. Various guides were not up to these requirements and broke during endurance tests or were extremely complex in design.

Solution

The solution was finally found in an E2 micro energy chain, which the designers initially tested to guide the electric cables. The result was so convincing that tests were also carried out with various hydraulic hoses. The hoses are guided through the E2 chain in several predefined radii. These radii are selected in such a way that the hoses deliver their full performance even in the lowest positions. A retaining bracket and a guide plate are used to position the energy chains correctly so that they cannot get caught on the side of the column.
