Tubbs Dilator

Description

Tubbs Dilator

The Tubbs mitral dilator stretches a narrowed mitral valve by opening its blades inside the orifice. Its range runs from 8 to 42 mm.

Tubbs mitral dilator: a wide 8 to 42 mm span

The blades start at 8 mm and open as far as 42 mm. So a single instrument handles both tight and fairly roomy openings. It also saves space compared with a row of fixed sizes.

Classic mitral use

Surgeons historically used this pattern for closed mitral commissurotomy. However, many teams still keep one for valve work and teaching. Its large range makes it useful whenever stepwise dilation helps.

Working in steps

First, the surgeon places the closed blades within the valve. Then the opening widens a little at a time while the team watches the result. In that case, the operator keeps full control of the final size.

Choosing between dilators

For openings under 15 mm, a smaller dilator may feel more precise. By contrast, the Tubbs mitral dilator covers adult mitral dimensions up to 42 mm. Plus, having both lets the team work across ages.

Reprocessing Tubbs mitral dilator

Rinse the blades while they stand open so blood cannot settle between them. Next, inspect the tips under good light for any nicks. Then dry the dilator completely and lay it flat in a padded tray.
