摘要： A surgical system and corresponding methods for identifying tissue or vessels and assessing their conditions includes a probing signal source for applying a probing signal to the tissue and a response signal monitor for monitoring a response signal that varies according to the level of blood circulation in the tissue or vessels. The response signal monitor monitors the response signal over an interval equal to or longer than an interval between two successive cardiac contractions. The surgical system includes a microprocessor that analyzes the amplitude and/or phase of the response signal to determine the level of blood circulation in the tissue or in different portions of the tissue, and determines a tissue parameter based upon the level of blood circulation. The surgical system may monitor a cardiac signal related to cardiac contractions and correlate the response signal and the cardiac signal to determine a level of blood circulation in the tissue.

摘要： The present invention provides devices and methods for applying radiation to the retina of a patient. In one embodiment, an apparatus includes a radiation source for generating a radiation beam suitable for absorption by retinal pigment epithelial cells. One or more optical components are included to direct the beam onto the retina. A scanner is optically coupled to the radiation source to control movement of the beam in two dimensions to allow a scan over the retina. A controller applies control signals to the scanner to adjust beam movement to illuminate a plurality of retinal locations in a temporal sequence according to a predefined pattern. The device can be operated in one mode to effect selective targeting of retinal pigment epithelial cells, or in another mode to effect thermal photocoagulation of the retina.

摘要： A surgical device based on the concept of controlling the laser power during laser surgery based on optical and other signals from the tip and the tissue is described. A laser surgical system generally comprises several basic components, such as a laser, a delivery system, a tip and a control system. A tip may be considered as a particular case of a thermo-optical tip (TOT). TOT is an optical and mechanical element which could be used to modify or treat soft and hard tissues, including cutting, coagulation, vaporization, carbonization, and ablation of tissues.

摘要： An electrosurgical generator apparatus controls a variable output signal to electrodes. The generator apparatus operates in a cut mode, a coagulation mode or a stimulate mode. The generator apparatus comprises a DC power supply that provides regulated low voltage and high voltage outputs and a radio frequency (RF) waveform generator circuit that provides pulse duration modulation (PDM) of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes. A control circuit controls a variable output signal to electrodes used in electrosurgical procedures. The control circuit comprises a DC power supply circuit that provides regulated low voltage and high voltage outputs and an RF waveform generator circuit that provides pulse duration modulation of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes.

摘要： A fractional treatment system can be configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue increases as the tissue is heated by the laser (e.g., 1390-1425 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 8 cm−1 to about 30 cm−1. An adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. The system may be designed to be switchable between a treatment mode that is semi-ablative and a treatment mode that is not semi-ablative. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements.

In one aspect, the fractional treatment is configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue decreases as the tissue is heated by the laser (e.g., 1480-1640 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 7 cm−1 to about 26 cm−1.
