Hemostatic Sheet and Gel for Combined Oral Nasal Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ENT surgical practices require multiple operative sessions for multiple procedures, causing patient trauma, increased costs, and inefficiencies due to the need for prolonged hemostatic packs in nasal cavities, which obstruct airflow and preclude simultaneous oral and nasal surgeries.
Innovation Solution
The method employs hemostatic sheet material and gel treatments instead of conventional sutures or cauterization, allowing for multiple oral and nasal surgical procedures to be performed in a single session by using an endotracheal tube for breathing and removing packs post-surgery, with disposable kits containing necessary instruments and medications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hemostatic packs are used to stop bleeding after surgery, then hemostasis is achieved, but nasal airflow is obstructed requiring mouth breathing which causes throat irritation and precludes simultaneous oral surgery
Solution Approach 1:
The patent extracts the hemostatic function from the obstructive cotton/gauze packs and implements it through a different mechanism - electrocautery sealing of blood vessels. This removes the harmful nasal packing while maintaining effective hemostasis, allowing patients to breathe through their noses post-operatively and enabling combined oral and nasal procedures
Solution Approach 2:
The patent replaces the mechanical compression method (cotton/gauze packs) with an energy-based method (electrocautery). The electrocautery device uses electrical energy to seal blood vessels, achieving hemostasis without physical obstruction of the nasal airway, thus resolving the contradiction between effective bleeding control and maintained nasal airflow
2Reliability
If multiple surgical procedures are performed in separate operative sessions, then each procedure can be optimized, but patient trauma increases, costs rise, and hospital efficiency decreases
Solution Approach 1:
The patent merges multiple separate surgical procedures into a single combined operative session. By eliminating the requirement for nasal packing through electrocautery hemostasis, the surgeon can simultaneously or sequentially perform nasal procedures (requiring nasal packing in traditional approaches) and oral procedures (such as tonsillectomy or adenoidectomy) without compromising patient comfort or safety, thereby improving hospital productivity and reducing patient trauma
Solution Approach 2:
The electrocautery device serves multiple functions: it provides hemostasis during nasal surgery, enables safe combined oral-nasal procedures, and eliminates the need for post-operative nasal packing. This multi-functionality allows a single surgical approach to address multiple procedural needs, improving overall surgical efficiency and reducing the number of separate operative sessions required
3Reliability
If multiple surgical procedures are performed in separate operative sessions, then healing can be monitored between procedures, but additional anesthesia risks accumulate and treatment time increases
Solution Approach 1:
The patent combines multiple procedures that would traditionally require separate sessions into a single operative session. By using electrocautery to eliminate the need for nasal packing, the surgeon can perform nasal surgery alongside oral surgery without extending recovery time or requiring multiple anesthesia exposures, thus reducing total treatment time while maintaining appropriate healing monitoring through a single post-operative course
4Reliability
If cotton or gauze packs are used for hemostasis, then bleeding is controlled, but the packs must remain in place for one to two days causing patient discomfort and requiring mouth breathing
Solution Approach 1:
The patent substitutes the mechanical compression hemostasis method (cotton/gauze packs requiring prolonged insertion) with electrocautery energy-based hemostasis. This provides immediate bleeding control during surgery without the need for prolonged nasal packing, thereby eliminating patient discomfort associated with mouth breathing and nasal obstruction while maintaining effective hemorrhage control

AI summary
The method of performing multiple oral and nasal surgical procedures in the head and neck region provides a systematic procedure for the performance of multiple operations for correcting various ear, nose, and throat conditions that cause snoring and obstructive sleep apnea (OSA) in the patient. The method allows the surgeon to perform multiple operating procedures in the nose, mouth, and/or throat in a single operating session, due to the use of hemostatic sheet and gel treatments in lieu of suturing and post-operative nasal hemostatic packs that preclude nasal breathing. The various surgical implement kits allow the surgeon to select the appropriate kit according to the procedure(s) to be performed. The procedure(s) is/are selected in accordance with a specific customized treatment plan that is developed by the surgeon for the individual patient, which other surgeons involved in snoring or OSA surgery can comprehend.
