Disposable Surgical Containment Shield for Spatter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Orthopedic surgical procedures involving power tools result in spatter of biological material, reducing visibility and increasing contamination risks for operating room personnel and equipment, due to inadequate containment and rebounding debris.
Innovation Solution
A disposable containment shield that mounts on surgical cutting instruments, featuring a transparent, pliable body with angled faces and a mounting hole, designed to block spatter and include a suction port for smoke and vapor removal, reducing secondary contamination and improving visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If surgical cutting instruments are used to increase cutting speed and accuracy, then surgical procedure efficiency is improved, but spatter of biological material increases causing reduced visibility and contamination risks
Solution Approach 1:
A transparent shield is introduced as an intermediary component between the surgical cutting instrument and the surgeon's face. The shield intercepts and contains biological material spatter before it can reach the surgeon's face, while maintaining visual clarity through its transparent construction. This allows the surgeon to continue using high-speed power tools efficiently without compromising visibility or safety.
Solution Approach 2:
The shield is constructed from a transparent, flexible material that can be contoured to fit various surgical instrument configurations. This thin film structure provides effective spatter containment while maintaining optical transparency, allowing the surgeon to see through the shield clearly during the procedure.
2Reliability
If face shields are used to protect against spatter, then personnel protection is improved, but visibility is reduced due to inadequate cleaning and spatter accumulation
Solution Approach 1:
The transparent shield is designed as a disposable component that can be easily replaced between procedures. Rather than requiring extensive cleaning and maintenance of permanent face shields, the disposable nature of this shield ensures optimal visibility for each use while providing reliable protection, as each new shield starts free from spatter accumulation.
Solution Approach 2:
The shield's transparent flexible material maintains high optical clarity while providing spatter containment. The transparency allows unobstructed vision during surgery, and the smooth surface prevents spatter adhesion that would otherwise degrade visibility over time.
3Object-affected harmful factors
If standard face shields are used, then primary contamination is reduced, but secondary contamination occurs due to rebounding debris affecting back, top, and underside surfaces
Solution Approach 1:
The shield extends beyond the traditional face shield configuration to create a three-dimensional containment structure that wraps around the surgical instrument. This dimensional extension captures rebounding debris that would otherwise travel backward, upward, or downward, containing it within the shield's protective envelope and preventing secondary contamination of the operating room environment.
Solution Approach 2:
The shield acts as an intermediary barrier that not only protects the surgeon's face but also intercepts rebounding spatter before it can reach other surfaces in the operating room. By positioning the shield strategically around the instrument, it serves as a first line of defense against both direct and rebounding contamination pathways.
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
The containment shield effectively reduces biological and non-biological material spatter, enhancing surgical visibility and safety by containing debris and smoke, thereby minimizing contamination and improving operating room cleanliness.
Implementation Method 1
The containment shield substantially blocks or contains spatter from impacting the patient or subject, operating room personnel, and operating room equipment
Implementation Method 2
include a suction port for smoke and vapor removal

AI summary
A disposable containment shield is operable to mount on an output housing of a surgical cutting instrument to keep spatter off of a surgeon's face shield enabling quick and complete restoration of visibility while cutting biological material. The containment shield includes a body that is substantially transparent and has a generally consistent thickness such that the body is pliable and resilient. The body is substantially planar and sterile when in the package. The containment shield forms into a three dimensional shape having a distal face and a proximal face, and a mounting hole of the containment shield engages onto the output housing of the surgical cutting instrument such that the distal face is at an acute angle with respect to a longitudinal axis through the mounting hole and faces toward a cutting device of the surgical cutting instrument.
