Total core biopsy devices and methods of use are provided for taking a total core biopsy sample and a means for using the devices that provide for an adequate sample size and quality while being light-weight, easy to use, small, inexpensive, and permitting one-handed operation and beveled edges to reduce trauma to the surrounding tissue and organs from which a total core biopsy sample may be taken.

Total core biopsy device and method of use

Among other things, there is disclosed a biopsy needle capable of taking samples of varying size. In particular embodiments, a user selects one of a plurality of sample-size settings, which sets the needle to a particular cannula throw-length by moving an internal wall against which a spring engages. For a shorter throw, the wall is in a forward position and the cannula is retracted the smaller amount to compress the spring. For a longer throw, the wall is in a rearward position and the cannula is retracted a larger amount to compress the spring.
