Surgical Suture Holder with Tapered Insertion and Recessed Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hemostatic clamps used in cardiovascular surgery occupy too much space near incisive openings or thoracic surgical fields, making it difficult for surgeons to manage small incisions or temporarily close thoracic surgical fields without increasing infection risk or prolonging recovery time.
Innovation Solution
A surgical suture holder designed to be compact and adaptable, featuring an insertion section for easy placement into a tubular snaring object, a holding section with recessed slots to securely hold surgical sutures, and a winding section to manage suture tension, allowing for efficient use of space during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hemostatic clamp is used to hold a surgical suture, then the suture can be securely held, but the clamp occupies too much space in areas near an incisive opening or thoracic surgical field
Solution Approach 1:
The suture holder is divided into distinct functional sections: an insertion section with tapered surface for inserting into the tubular snaring object, and a holding section with a holding board that has holding slots for securing the suture. This segmentation allows each part to perform its specific function efficiently while keeping the overall device compact.
Solution Approach 2:
The suture holder is designed to be inserted into and nested within the tubular snaring object, which itself is positioned within the surgical field. This nested configuration allows the suture holding function to be achieved within the confined space of the existing surgical apparatus, eliminating the need for additional external clamp space.
2Adaptability or versatility
If multiple conventional hemostatic clamps are used in surgery, then multiple sutures can be held, but the surgical field requires larger incisive opening or remains partially closed, increasing infection risk
Solution Approach 1:
The holding board can accommodate multiple holding slots to secure multiple sutures simultaneously, and the tubular snaring object can receive multiple suture holders. This multi-functional design allows a single surgical field configuration to handle multiple sutures without requiring multiple separate clamp applications, thereby maintaining surgical field closure integrity.
3Reliability
If a conventional hemostatic clamp is used in a small incisive opening, then the suture can be held, but the surgeon has difficulty in using the clamp due to space constraints
Solution Approach 1:
The insertion section has a tapered surface specifically designed with a gradual angle to facilitate easy insertion into the tubular snaring object through small openings. This localized geometric feature addresses the specific operational challenge of inserting the device through constrained access paths while maintaining the overall structural integrity needed for reliable suture holding.

AI summary
A surgical suture holder is adapted to be disposed on an opening of a tubular snaring object, is adapted for holding at least one surgical suture, extends along a holder axis, and includes an insertion section and a holding section. The insertion section is adapted to be inserted into the opening of the tubular snaring object and being tapered toward the tubular snaring object. The holding section has a holding board that has a periphery surrounding the holder axis, and at least one holding slot that is recessed from the periphery of the holding board, that extends through the holding board in an extending direction of the holder axis, and that is adapted for the at least one surgical suture to fit thereinto so that the holding slot holds the at least one surgical suture.
