Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing iridectomy procedures face challenges in accurately controlling the size and position of iris incisions, leading to iris hemorrhage and increased surgical complications, particularly in glaucoma and corneal transplantation surgeries.
Innovation Solution
A punching-type iridotomy instrument with a grip manipulation part, extension shaft, and punching operating unit, featuring interchangeable incision members and adjustable components to precisely form holes in the iris, mimicking the operation of scissors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgical scissors are used to cut the iris, then the surgery can be performed, but it is difficult to control the exact location and size of the iris incision and may cause iris hemorrhage
Solution Approach 1:
The iris incision tool is divided into separate functional components: a positioning fork that defines the incision location and size, and a separate cutting blade. This segmentation allows independent optimization of positioning accuracy and cutting precision, eliminating the control difficulties associated with using scissors.
Solution Approach 2:
The patent introduces a positioning fork as an intermediary element between the surgeon's control and the iris tissue. The fork's tip distance from the cornea surface precisely determines the incision location and size, acting as a mechanical mediator that translates surgical intent into accurate tissue intervention without direct contact control issues.
2Productivity
If traditional iridectomy method is used, then the procedure can be completed, but the surgery time is extended and operational convenience is reduced
Solution Approach 1:
The patent combines multiple functions into a single integrated tool: positioning, measurement, and cutting are all performed by one instrument. The positioning fork and cutting blade work together as a unified system, eliminating the need for separate positioning and cutting steps, thus reducing surgery time while maintaining ease of operation.
Solution Approach 2:
The positioning fork is designed to be inserted and positioned before the cutting action. The fork's predetermined geometry establishes the exact incision location and size in advance, allowing the subsequent cutting step to be performed quickly and accurately without repeated adjustments or measurements during surgery.

AI summary
The present invention relates to a punching-type iridotomy instrument, and more particularly, to a punching-type iridotomy instrument which, in iridectomy, increases the size and positioning accuracy iris incision through structural improvement in a perforation method, thereby shortening the surgery time and facilitating the convenience of surgical procedures. According to the present invention, the punching-type iridotomy instrument includes a grip manipulation part configured to be manipulated to be opened or closed by a user while being held by the user's hand, an extension shaft extending from the grip manipulation part, and a punching operating unit extending from the extension shaft and configured to perform an operation of forming a hole in a predetermined site of a peripheral portion of an iris in conjunction with an operation of the grip manipulation part performed by the user's manipulation, in which the grip manipulation part includes a first round shaft extending from a rear side of the extension shaft and having a first finger grip ring formed at an end of the first round shaft and configured to be fitted with the user's thumb, a second round shaft hingedly coupled to a predetermined position on the extension shaft by a pivot pin and having a second finger grip ring formed at an end of the second round shaft and configured to be fitted with the user's ring finger, the second round shaft being configured to implement a rotational operation related to a motion of the ring finger fitted into the second finger grip ring, a spring disposed between the first and second round shafts and configured to exert elasticity for pushing the second round shaft, and a wire configured to connect the second round shaft and the punching operating unit while passing through the extension shaft and operate the punching operating unit in conjunction with a rotational operation of the second round shaft.
