There are different cutting or biting mechanisms employed in various
Transforaminal Endoscopic Rongeur forceps designs to suit different surgical needs and applications. The choice of rongeur design often depends on the specific characteristics of the tissue or bone being removed, as well as the surgeon's preferences and the requirements of the surgical procedure. Here are some common cutting or biting mechanisms found in different rongeur designs:
Cupped Jaws:
Rongeurs with cupped jaws have a concave cutting surface, resembling a cup. This design is effective for grasping and removing larger fragments of bone or tissue. Cupped jaws are often used in orthopedic and spinal surgeries.
Concave Jaws:
Similar to cupped jaws, concave jaws have a curved cutting surface, but the curvature is less pronounced. This design is suitable for more precise cutting and is commonly used in neurosurgical procedures.
Angled Jaws:
Some rongeurs have jaws that are angled relative to the handle. Angled jaws provide better access to specific anatomical structures and can be useful in confined spaces, such as during spinal surgeries.
Straight Jaws:
Rongeurs with straight jaws are versatile and can be used for a variety of applications. They are often employed when a straightforward cutting action is required without a specific curvature.
Double-Action Jaws:
Double-action rongeurs have jaws that open laterally, allowing for a larger opening and better access to the surgical site. This design is advantageous when dealing with larger bones or tissues.
Basket Grasping Mechanism:
Some rongeurs have a basket-like mechanism that facilitates the grasping and removal of bone or tissue fragments. This design is particularly useful in spinal surgeries where fragments need to be extracted through a narrow opening.
Fenestrated Jaws:
Rongeurs with fenestrated jaws have openings or perforations in the cutting surface. This design helps in reducing the weight of the instrument and allows for improved visibility during surgery.
Rotating Jaws:
In certain rongeur designs, the jaws may have a rotating mechanism. This feature allows the surgeon to reposition the jaws without manipulating the entire instrument, enhancing precision during the cutting process.
Ratchet Mechanism:
Some rongeurs incorporate a ratchet mechanism in the handles, providing a controlled and incremental closing action. This can be beneficial for exerting precise force during cutting or biting.
Fine Tip Design:
Rongeurs with fine tips are designed for delicate procedures where precision is crucial. The fine tips allow for controlled cutting in small or intricate spaces.
