The Lotke Double Action Cartilage Graspers are designed for controlled grasping and secure handling of cartilage and soft tissues during orthopedic surgical procedures. Their double-action mechanism provides increased mechanical advantage at the working end, helping the user securely hold tissue during manipulation.
Two configurations are available: a Standard version and a Ratcheted version. Both have an overall length of 7.5" (19.1 cm), while the ratcheted configuration adds a ratcheting mechanism for maintaining the selected grip.
Key Features
- Double-action design for increased gripping strength
- Designed to securely hold cartilage and soft tissues
- Available in Standard and Ratcheted configurations
- 7.5" (19.1 cm) overall length for both configurations
- Ratcheted version provides an additional grip-maintaining mechanism
- Suitable for controlled tissue grasping and manipulation
- Designed for orthopedic surgical applications
Double-Action Mechanism
The double-action construction is designed to increase the mechanical movement of the jaws in relation to the handle movement. This provides a controlled gripping action while helping generate the force needed to securely engage soft tissue and cartilage.
The design can be useful when a firm, controlled hold is required during tissue manipulation.
Standard Configuration
The Standard configuration provides the double-action gripping mechanism without the additional ratcheting feature.
Specifications:
- Configuration: Standard
- Overall Length: 7.5" (19.1 cm)
- Mechanism: Double Action
This version is suitable when continuous manual control of the grasp is preferred.
Ratcheted Configuration
The Ratcheted configuration incorporates a ratcheting mechanism in addition to the double-action design. This allows the selected grip to be maintained through the ratchet rather than requiring continuous manual pressure.
Specifications:
- Configuration: Ratcheted
- Overall Length: 7.5" (19.1 cm)
- Mechanism: Double Action with Ratchet
The ratcheted design can be useful when maintaining a consistent grasp on cartilage or soft tissue is required during a procedure.
Working-End Function
The grasping jaws are designed to securely engage cartilage and soft tissue while the double-action mechanism provides controlled jaw movement.
The instrument should be positioned carefully around the intended tissue structure, with the appropriate amount of pressure applied for the specific surgical task.
Surgical Applications
The Lotke Double Action Cartilage Graspers are intended to assist with:
- Cartilage grasping
- Soft-tissue grasping
- Controlled tissue manipulation
- Holding tissue during orthopedic procedures
- Maintaining a secure grip during surgical manipulation
The appropriate configuration should be selected according to the surgeon's preferred handling technique and whether a ratcheting mechanism is required.
