Study of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...

15 صفحه اولMenorrhagia: endometrial ablation or hysterectomy?
BACKGROUND For many woman who suffer from menorrhagia, treatment would previously have meant hysterectomy. Today there are a number of less invasive surgical options available, such as endometrial ablation, which involves removal of the endometrium and part of the myometrium. This article compares two endometrial ablative techniques--transcervical resection of the endometrium and thermal balloo...
متن کاملLate-onset endometrial ablation failure
Endometrial ablation, first reported in the 19th century, has gained wide acceptance in the gynecologic community as an important tool for the management of abnormal uterine bleeding when medical management has been unsuccessful or contraindicated. The introduction of global endometrial ablation (GEA) devices beginning in 1997 has provided unsurpassed safety addressing many of the concerns asso...
متن کاملEndometrial ablation with paracervical block.
OBJECTIVE To evaluate the safety, feasibility and efficacy of endometrial ablation under local anesthesia. STUDY DESIGN A prospective cohort study was performed at the gynecology department of a large teaching hospital. Women with dysfunctional uterine bleeding were included to undergo NovaSure endometrial ablation with paracervical block. We measured the acceptability, pain score (visual ana...
