Gravity-Driven Anesthetic Applicator for Hiatal Hernia Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hiatal hernia surgeries often result in significant postoperative pain, requiring high doses of pain medication and prolonging recovery, due to extensive tissue dissection and trauma during the repair process.
Innovation Solution
A method involving the use of gravity-driven anesthetic applicators to directly apply anesthetic to the area of repair, including the hiatus and diaphragm, without pressurization, to reduce pain and enhance recovery by numbing the affected areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive tissue dissection is performed during hiatal hernia repair, then the hernia can be effectively repaired, but postoperative pain increases and recovery is prolonged
Solution Approach 1:
The anesthetic solution is applied to the area of repair before the surgical incision is closed, providing preliminary anesthesia to the tissue that will be manipulated during the repair procedure. This preliminary action reduces pain during and after the extensive tissue dissection required for effective hernia repair.
Solution Approach 2:
An anesthetic solution is introduced as an intermediary substance between the surgical tissue and the patient's nervous system. The solution contains local anesthetics that block pain signals, mediating the harmful effect of tissue dissection by preventing pain perception without affecting the surgical repair itself.
2Object-affected harmful factors
If high doses of pain medication are administered, then postoperative pain is controlled, but recovery time is prolonged and patient comfort is reduced
Solution Approach 1:
By applying anesthetic solution to the area of repair before closing the surgical incision, the procedure establishes preliminary pain control that lasts for several hours after surgery. This preliminary action reduces or eliminates the need for high doses of postoperative pain medication, thereby accelerating recovery and improving patient comfort.
Solution Approach 2:
The patent replaces the mechanical system of intravenous pain medication administration with a direct local application system. The anesthetic solution is delivered directly to the tissue through applicators, substituting the need for systemic pharmacological intervention and its associated recovery delays.
3Speed
If pressurization is used to apply anesthetic, then anesthetic delivery is rapid, but tissue trauma and pain increase
Solution Approach 1:
The patent replaces pressurization-based anesthetic delivery with a gravity-driven system. The anesthetic solution flows from a reservoir through applicators powered solely by gravity, eliminating the need for mechanical pressurization devices. This substitution maintains adequate anesthetic delivery speed while completely avoiding the tissue trauma and pain associated with pressurization.
Solution Approach 2:
The gravity-driven system allows the anesthetic solution to flow automatically from the reservoir to the applicator without external power or pressurization. The system serves itself using the natural force of gravity, providing continuous anesthetic delivery without requiring additional mechanical intervention that could cause tissue trauma.

AI summary
An improved hiatal hernia treatment enhances recovery after surgery by reducing a patient's pain at an area of treatment. The area of treatment contains the hiatal hernia and must be extensively divided before the hiatal hernia can be treated. The improved hiatal hernia treatment reduces the patient's pain through directed application of an anesthetic via an applicator positioned within the area of treatment. The reduction of the patient's pain increases the patient's comfort, reduces the need for pain medication, and lowers the patient's blood pressure to enhance recovery.
