TISSUE HOLDER FOR EXPERIMENTAL

AND DEMONSTRATION SURGERY 
A problem in experimental and/or demonstration 
surgery is the difficulty of holding fresh tissue in a proper 
position. This difficulty has been overcome by the use of 
a tissue holder employing vacuum or suction (see photo-
graph). 
The problem of holding excised animal eyes for surgery 
arose from a project concerned with the development and 
evaluation of a new eye surgical tool and technique. 
Because of the softness and slipperyness of the eye tissue, 
holding the eye in a proper position while surgery was 
performed was very difficult. The problem was solved by 
constructing a plastic dish having in its center a hemis-
pherical recess approximately the size of the excised eyes. 
A hole drilled in the bottom of the recess is connected to 
a vacuum line. A low vacuum applied to the hole holds 
the eyeball firmly in the recess. The walls of the 
hemisphere are grooved vertically from the vacuum hole 
upward nearly to the surface of the dish. These grooves 
keep the eyeball from rotating in the recess during surgery 
(see sketch).
NOTES: 
1. With slight modifications, the holder can be used for 
retaining other types of tissue for examination and/or 
surgery. 
2. No additional documentation is available. Specific 
questions, however, may be directed to:
