VACUUM ACTUATED TISSUE LIFTING DEVICE |
摘要 |
<p>A vacuum-actuated tissue lifting medical device for creating an operative space in a patient for a surgical procedure is disclosed. The device includes a housing having an opening for resting on a tissue surface of a patient. The housing defines an expansion space between the housing and the tissue surface for application of a negative pressure in the expansion space. A penetrator device located within the housing can penetrate into the tissue surface of the patient. A vacuum system is in fluid communication with the housing for creating a negative pressure in the expansion space for advancing the tissue surface onto the penetrator device such that an operative work space is created beneath the tissue surface. A regulator controls the negative pressure in the housing when (i) the negative pressure in the expansion space exceeds a value; (ii) the pressure in the operative work space exceeds a value; or (iii) a combination of (i) and (ii).</p> |
