Angled Surgical Power Tool Handle for Slippage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical power tools often result in slippage during procedures, leading to potential injuries to the patient due to the need for significant effort to maintain accurate control and apply pressure effectively.
Innovation Solution
A surgical power tool with a head portion and shaft where the tool axis is angled relative to the shaft axis, featuring a handle portion with a clamping element to securely attach the handle to the shaft, allowing for precise pressure application and adjustable angles to facilitate easier access to the surgical site, and optionally including illumination, rinsing, and viewing devices.

Engineering Contradiction Analysis
1Force
If the surgeon exerts pressure on the gripping shaft to maintain control and apply force, then the force transmission to the tool is improved, but the risk of slippage and patient injury increases
Solution Approach 1:
The device is divided into a gripping shaft and a handle portion that can be independently positioned and secured. The handle portion can be clamped to the shaft at different positions and angles, allowing the surgeon to apply force on the handle while the tool remains secured to the shaft, separating the force application point from the tool attachment point.
Solution Approach 2:
The handle portion can be positioned at different angular orientations relative to the shaft through the clamping mechanism. This angular adjustment capability allows the surgeon to find an optimal handling angle that provides better leverage and control, reducing the need for excessive force application.
2Ease of operation
If the tool axis is angled with respect to the shaft axis, then the access to surgical site is improved, but the control stability deteriorates
Solution Approach 1:
The handle portion can be dynamically adjusted to different angular positions relative to the shaft using the clamping element. This allows the surgeon to optimize the angle for accessing difficult surgical sites while maintaining a secure, stable configuration through the clamping mechanism. The system transitions from a fixed rigid structure to an adjustable dynamic structure that can be optimized for each surgical scenario.

AI summary
A surgical power tool (1) is described. The surgical power tool comprises a head portion (20) having a tool (21) with a tool axis, a shaft (10) which is connected to the head portion for guiding the head portion to the surgical site and a handle portion (30) for exerting pressure to the head portion along the tool axis. The shaft has a longitudinal axis that is angled with respect to the tool axis.
