Hysteroscopy Injection Needle for Pre-Resection Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visual field of a hysteroscope can be obscured by bleeding from surrounding tissues during medical procedures, limiting the ability of healthcare providers to perform diagnostics and treatments safely, leading to longer operation durations and increased health care costs.
Innovation Solution
A hysteroscopy injection needle with a thinner, longer shaft designed to fit through a hysteroscope's sheath, featuring a beveled tip and a handle for precise tissue penetration, delivers a vasoconstrictor reagent like vasopressin to reduce bleeding and improve visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a standard hysteroscope is used for tissue resection, then the procedure can be performed, but bleeding from surrounding tissues obscures the visual field, limiting safe operation
Solution Approach 1:
The patent applies preliminary action by injecting vasoconstrictor medication into the tissue surrounding the fibroid before performing tissue resection. This pre-treatment causes blood vessels to constrict in advance, reducing bleeding during the subsequent surgical procedure and improving visual field clarity throughout the operation.
2Reliability
If bleeding occurs during hysteroscopic surgery, then the visual field is obscured, but stopping the procedure to address bleeding increases operation duration
Solution Approach 1:
By administering vasoconstrictors before tissue resection begins, the patent prevents excessive bleeding from occurring during the procedure. This eliminates the need to pause surgery to address bleeding, maintaining both safety and efficiency throughout the continuous operation.
3Reliability
If multiple procedures are performed to address bleeding and resection separately, then treatment completeness improves, but health care costs and anesthesia exposures increase
Solution Approach 1:
The patent merges two separate procedural steps into one integrated procedure: (1) injecting vasoconstrictor medication to control bleeding, and (2) performing tissue resection. This combination allows both hemostasis and tumor removal to be accomplished in a single surgical session, eliminating the need for separate procedures and reducing overall healthcare costs and anesthesia exposures.
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 needle allows for controlled bleeding and sustained visualization during hysteroscopic surgeries, reducing the need for additional procedures and anesthesia exposures, and decreasing health care costs.
Implementation Method 1
The liquid comprises a vasoconstrictor reagent. The vasoconstrictor reagent comprises vasopressin.

AI summary
The disclosure is directed to devices, systems, and methods for a hysteroscopy injection needle. One device for injecting a fluid into a tissue includes a shaft having an elongated lumen configured to deliver a fluid from a proximal end of the shaft to a distal end of the shaft; a handle fixed with the shaft, the handle configured to maneuver the distal end of the shaft at a tissue; and a connector at the proximal end of the shaft, the connector configured to receive a liquid handling device.
