Abstract

A medical device having a handle with a clamp configured to hold the device in two different modes of operation. The medical device includes a needle, a sheath, a sheath handle, a needle actuator and a locking device. The distal end of the needle actuator is connected to the proximal end of the needle. The distal end of the sheath handle is connected to the proximal end of the sheath. The locking device limits distal movement of the needle actuator relative to the sheath handle when the medical device is in one of two operational states. In the inactive state, the distal end of the needle is received within the distal end of the sheath. In an activated state, the distal end of the needle is remote from the distal end of the sheath.

Description

technical field [0001] The present invention relates to medical device handles for tissue sampling. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Some handle designs for medical devices, such as those used with needles used to collect samples from target tissue, use simple cantilever springs, friction fits, or O-rings. Earlier O-ring designs provided some "locking" capability using grooves to seat the O-ring. However, those grooves are generally shallow, which may also allow accidental advancement of the needle without user input, causing potential safety issues or scope damage. Contents of the invention [0004] The present invention provides an exemplary medical device for sampling tissue. The exemplary medical device includes a handle with a clamp configured to hold the device in two different modes of operation. [0005] According to asp...
