发明名称 Improved surgical needle configuration with spatula geometry.
摘要 <p>A spatulated needle is provided wherein a six-sided cross-sectional portion results from a parallel or tapered pair of upper and lower surfaces (14, 16) connected by needle walls (20a, 20b) and a pair of fluted edges (18a,18b). At the tapered end of the needle, the upper surface (14) alternates resulting in a five-sided cross-section (16, 18a, 18b, 20a, 20b). This improved configuration results in ease of tissue penetration, minimized tissue distortion, and minimized wound trauma. The resultant needle therefore is desirable for usage with refined surgery such as ophthamology, microsurgery and plastic surgery.</p>
