Sklar's Tischler Elliptical / Oval Biopsy Punch is a non-ratcheted, double spring OB/GYN instrument most commonly used in colposcopy procedures to obtain cervical tissue samples for biopsy. The bite of this standard Tischler punch is 3mm x 7mm and it produces an oval shaped tissue sample. It features a single, lower tooth used to grasp difficult to reach tissue and a locking mechanism above the horn on the handle so the jaws can lock the tissue sample into place while the instrument is removed from the cervical canal. This reduces the risk of losing the tissue sample as the instrument is withdrawn. A standard size biopsy punch may produce cause more bleeding and pain than a mini or baby punch; however, with certain diagnoses it is necessary to obtain a larger tissue sample. The length of the cannula/tip is approximately 8 inches. This product has a pistol style handle with one large ring for multiple fingers.
