Endoscopic ultrasound fine needle aspiration device

摘要

A handle for a medical device comprises a proximal segment (102) defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein (103). A medial segment (104) is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment (106) is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism (120) limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism (122) limiting advancement of an endoscope attached to the distal body portion.
