초록 ▼

An improved medical needle is disclosed which has a bioabsorbable gelatin cutting or puncturing tip formed therein. The gelatin characteristic renders the needle incapable of penetration after initial use. Additionally, the gelatin partially dissolves to leave a coating on the punctured tissue margin which acts to minimize hemorrhaging complications. Hemorrhaging complications are alternatively addressed by a non-bioabsorbable in situ sheath positioned at the punctured tissue site which compresses the tissue.

대표청구항 ▼

A biopsy needle for taking a biopsy specimen from a patient, said needle having an unactuated position defined by a relative position of its parts prior to insertion in the patient, an actuated position defined by the relative position of its parts while said specimen is being taken and a retracted position defined by the relative position of its parts when said needle is removed from the site where the biopsy was taken, said needle comprising: a) an inner cutting cannula having a distal portion for insertion into said site and a contiguous proximal portion extending from said distal portion, said distal portion defined as the length of said inner cannula which is inserted into said patient in said actuated position, and including means to sever said specimen from said patient; b) an outer hollow cannula co-axial with and receiving said inner cannula, said outer cannula having a proximal portion and a separable distal portion, said separable distal portion being separated from said proximal portion and remaining at said site in said retracted position of said needle; c) position means associated with said proximal portions of said inner and outer cannulas to cause movement of one of said cannulas relative to the other when said needle moves from one of said positions to the other; and d) said separable distal portion of said outer cannula remaining at said site and being sized relative to said inner cannula to compress site tissue thereat for minimizing bleeding or gas escape from said site after said needle is removed from said site.
