Title:
METHOD AND DEVICE FOR PROMOTION OF TISSUE REGENERATION ON WOUND SURFACES
Document Type and Number:
WIPO Patent Application WO2005009256
Kind Code:
A3
Abstract:
The invention relates to the promotion of tissue regeneration on wound surfaces (1), which, for example, should heal with other wound surfaces, heal over an implant, or heal to form tissue surfaces, whereby mechanical vibrations are introduced into said wound surfaces. A treatment instrument (2), coupled to a vibration source (electromechanical vibration converter), is used for the above, or an implant is subjected to vibrations during and/or after the positioning thereof in the tissue. Ultrasound vibrations are particularly suitable for the treatment. The vibrations have a mechanical and thermal effect in the region of the treated wound surface (1) and have a stimulating, traumatic, necrotic or cell-destroying effect according to intensity, whereupon biological elements which interfere with tissue regeneration are destroyed or denatured and the metabolism in the region of the wound surface is stimulated. The effect can also be mechanical, whereupon the tissue is lightly compressed or partly dislodged. The treatment can be carried out during or after the positioning of an implant thus the necrosis concerns in particular, undesired cells introduced to the wound surface with the implant, such as connective tissue cells, mucal cells or diseased cells which can interfere with the healing over of tissue and implant. The treatment instruments (2) or implants used for the treatment are embodied as vibrating bodies and are coupled or may be coupled to a vibrating drive or comprise a coupling surface on which a sonotrode may be placed. The above have surfaces for contact with energy guided transmitters.
