Surgical Clamp with Predetermined Breaking Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical tools with clamps used in bone surgery often cause damage to body tissue due to sharp edges formed during staple separation, and they require additional tools for drilling holes, cutting, and insertion, which can be cumbersome and difficult to adapt.
Innovation Solution
A surgical tool with a clamp and handle connected via predetermined breaking points, which minimizes sharp edge formation during staple separation, and includes a drilling aid integrated with the handle, allowing for precise hole positioning without the need for additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamp is separated from the handle at predetermined breaking points, then the clamp can be easily detached and used, but sharp edges are formed at the separation points which can damage body tissue
Solution Approach 1:
The patent applies preliminary action by pre-forming rounded contours at the predetermined breaking points before separation occurs. The handle and clamp are designed with pre-curved edges at the separation locations, so when breaking points are separated, no sharp edges are generated. This preliminary preparation eliminates the harmful effect of sharp edges while maintaining the ease of detachment.
2Adaptability or versatility
If additional tools are provided for drilling holes, cutting and insertion, then the surgical procedure can be completed, but the device complexity increases and tools must be individually adapted
Solution Approach 1:
The patent merges multiple surgical functions into a single integrated tool. The handle is designed to accommodate various surgical instruments (drills, cutters, insertion tools) through integrated receptacles or attachment mechanisms. This combining of multiple tools into one unified device reduces the number of separate instruments needed while maintaining complete surgical functionality.
Solution Approach 2:
The handle is designed with universal adaptability to perform multiple surgical functions. It can accommodate different types of surgical instruments through standardized interfaces or interchangeable components, allowing one tool to serve multiple purposes (drilling, cutting, insertion) without requiring individually adapted tools for each function.

AI summary
Disclosed are surgical tools (10) comprising a surgical clamp (20) having at least two, preferably exactly two legs (21) and a base (22) connecting the legs (21). The tools (10) comprise one or more of the following further elements: a handle (30) integrally connected to the clamp (20), wherein the handle (30) is connected to the base (22) of the clamp (20) via at least one first predetermined breaking point (91); a drilling aid (40) having at least two openings (41) whose distance (D) is greater than the distance (d) of the legs (21) of the clamp (20); a drill (50) which is connected, in particular at a first end (51), to the handle (30) via at least one third predetermined breaking point (93); a separation opening (42) which is designed in such a way that, in particular after separation of the drilling aid (40) from the handle (30), the clamp can be received in the separation opening (42), in particular in the region of the first predetermined breaking point (91), in such a way that the clamp (20) can be separated from the handle (30) at the first predetermined breaking point (91). More generally, there are also disclosed one-piece surgical tools (10; 10′) having at least two elements interconnected by predetermined breaking points.
