Surgical aspiration device for use in surgical operations, whereby the aspiration device is intended for use in atraumatic aspiration, tissue aspiration and disection. The surgical aspiration device comprises a handle with an inner tube and an outer tube which extend from the handle and which are arranged concentrically, with an interstice formed between them. Adjacent to the handle is an inlet opening which allows air into said interstice. When a vacuum is applied to the inner tube for aspiration, air passes into the interstice and into the inner tube, whereby the aspirated liquid column is broken and atraumatic aspiration can take place. |

DETAILED DESCRIPTION The above mentioned problems have now unexpectedly become capable of solution by the present invention, whereby the liquid column mentioned may be broken and suction adheration is counteracted.
The invention relates to a surgical aspiration device comprising a tubular handle, which at one end thereof has an outlet for connection to a vacuum source, and which at the other end thereof has a projecting point aspirator shaped as a tube which at least at its front end is provided with an axially (frontally) arranged aspiration opening.
The invention is characterized in that the handle further is provided with an outer tube arranged substantially concentically with the point aspirator, which outer tube extends along the entire point aspirator and which has an opening at its front end adjacent to the front end of the point aspirator, whereby an interstice is arranged between the outer tube and the point aspirator, and whereby the outer tube has an air inlet opening adjacent to the handle, through which opening air is allowed to pass along the outside of the point aspirator to the aspiration opening thereof.
An embodiment of the invention is characterized in that the outer tube extends further beyond the front end of the point aspirator.
A further embodiment of the invention is characterized in that the point aspirator is arranged without any joint to the outer tube at its front end.
A still further embodiment of the invention is characterized in that the outer tube and the point aspirator are joined to each other at the front ends thereof, whereby the point aspirator has at least one laterally arranged opening adjacent to the front end thereof, for connection between the interior of the point aspirator and the interstice.
A further preferred embodiment of the invention is characterized in that the point aspirator at its front end has at least one further laterally arranged opening connecting the interior of the point aspirator with the interstice.
Another preferred embodiment of the invention is characterized in that the outer tube is held axially displaceable in relation to the handle
