1.0 INTRODUCTION
1.1 General Description
The model 6850 PROfx Pelvic Reconstruction Orthopedic Trauma Table (6850 Table) is
designed to safely hold a patient in the proper position undergoing orthopedic or surgical
procedures.
It is a stand-alone, single-pedestal electrically operated table designed to position a patient in a
prone, lateral or supine position during surgical procedures. The table has three primary
electrically powered functions. Up/down, left/right lateral roll, Trendelenburg/Reverse
Trendelenburg tilt. Electromechanical actuator-motors perform these motions.
The table is controlled by means of a hand pendant control with functions clearly labeled.
Positive floor locks are employed to stabilize the table in the operating location.

at any point within its physical range. The table has a height range of 30 to 40 inches. The width
of the tabletop is 21 inches. The length of the tabletop is 62 inches. With leg spars is 125 inches.
The lateral roll range is +/- 20 degrees and the Trendelenburg range is +/- 15 degrees. The
maximum deflection of the tabletop under full load is less than 1 inch at the cantilever end. The
tabletop has a radiolucent equivalency of less that 1-mm of aluminum. The input power
requirement is 110 VAC, 60Hz or 230 VAC AC 50 Hz as indicated on the table label. This is a
Class 1 exempt type B Medical Device with an IPX-0 rating, 10% duty cycle or 6 minutes per
hour.
1.3 Shipping
The 6850 Table must be shipped using appropriate Shipping Crate (OSI part number [p/n] 6800-
400) and Shipping Instructions (p/n NW0408). During shipment the 9650 Table is to be kept in
an environment within the following limits:
1. Ambient temperature -20 degrees C to + 50 degrees C

all sides.
4. Perform Pre-Operational function check.
3.2 Preoperative
Perform Pre-Operational function check.
3.3 Postoperative
Perform Pre-Operational function check.
3.4 Annually
• Inspect and test the 6850 Table as described Pre-Operational function check. Thoroughly
clean the table as described in the CLEANING and MAINTENANCE section of this manual.
Pay special attention to the cleanliness of the controls as excessive soil could affect function.
