Adjustable Pressure Surgical Clamp with Remote Manipulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laparoscopic and endoscopic surgeries require instruments that can apply adjustable pressure to tissues without causing trauma, while minimizing the number of instruments in the surgical site to ensure precise and comfortable movement for surgeons, as traditional forceps often lead to longer surgeries and tissue damage.
Innovation Solution
A surgical clamp with a remote manipulator and adjustable pressure clamp, featuring two jaws that open and close simultaneously, allowing for secure grip and release of tissues with adjustable force, and suture thread apertures for connection with other instruments, designed to accommodate various tissue types and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional forceps are used for tissue manipulation, then the surgical procedure can be performed, but the surgical time increases and tissue trauma occurs
Solution Approach 1:
The clamp incorporates an adjustable pressure mechanism that allows dynamic modification of clamping force during surgery. The spring-loaded system with adjustable preload enables the clamp to adapt to different tissue types and surgical requirements, providing sufficient grip without excessive force that causes trauma.
Solution Approach 2:
The invention changes the pressure parameter from fixed to variable through the adjustable spring mechanism. By modifying the spring preload, the clamping force can be optimized for each specific surgical situation, preventing both tissue release and trauma while improving surgical efficiency.
2Adaptability or versatility
If multiple surgical instruments are placed in the surgical site, then various surgical tasks can be performed, but the surgical site becomes cluttered and movement precision decreases
Solution Approach 1:
The clamp is designed with multiple functions: tissue grasping, secure holding with adjustable pressure, and suture attachment capability through apertures. This multi-functionality reduces the need for multiple separate instruments in the surgical site, improving movement precision while maintaining versatility.
Solution Approach 2:
The invention combines the gripping function, pressure adjustment mechanism, and suture attachment capability into a single integrated clamp device. This consolidation reduces instrument clutter in the surgical site while providing comprehensive surgical capabilities.
3Device complexity
If fixed pressure clamps are used, then the device structure is simple, but the clamp cannot adapt to different tissue types and may cause tissue release or trauma
Solution Approach 1:
The clamp transitions from a static fixed-pressure design to a dynamic adjustable-pressure system. The spring mechanism with adjustable preload allows the clamp to adapt to different tissue types and surgical requirements, improving versatility while maintaining reasonable structural simplicity.
4Ease of manufacture
If non-adjustable clamps are used, then the manufacturing is simpler, but the clamp cannot provide optimal grip for different tissue types
Solution Approach 1:
The invention introduces adjustable pressure as a variable parameter through the spring mechanism. This allows optimization of grip security for different tissue types while maintaining a relatively simple manufacturing process compared to more complex actuation systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise and trauma-free tissue manipulation, reducing surgical time and tissue damage by providing adjustable clamping force and allowing for efficient use of multiple instruments without cluttering the surgical site.
Implementation Method 1
A compression spring is positioned around the pressure bar and is secured thereon and partially compressed by a nut positioned on the threaded end section of the pressure bar. Adjustment (rotation) of the nut varies the compression on the spring and thereby varies the gripping force between the jaws of the clamp.

AI summary
A surgical clamp for laparoscopic or endoscopic surgeries provides autonomous adjustable pressure and placement with a releasable or integrated remote manipulator. Two jaws move simultaneously with respect to the main body of the clamp to open and close to secure or release tissue and/or organs. In a first embodiment, the instrument is made up of two separable components; a remote manipulator component, and a releasable adjustable pressure clamp component that is linked or separated at an interlocking connection point. The main body of the clamp includes a central tubular port through which a pressure bar passes. An assembly of cam arms connects the push rod to jaws, allowing for symmetrical and simultaneous actuation. A compression spring is positioned around the pressure bar and is secured by an adjustable nut on the threaded end of the pressure bar. Adjustment varies the compressive force of the spring and thereby the gripping force.
