Deep Channel Suture Device With Segmented Needle Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional single needle suture devices are inefficient for deep channel sutures, as they are difficult to operate and can cause more tissue damage due to their design, limiting their effectiveness in deeper wounds.
Innovation Solution
A suture device with a hollow suture hooking rod, a hollow tubular puncture needle, and two push needles, featuring a segmented pinhead and elastic components for quick operation, allowing for easier insertion and retrieval of sutures and reducing tissue damage through a double-needle segment structure that minimizes puncture resistance while maintaining strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional single needle suture device is used, then the suture process can avoid needle scratching tissue during shuttling, but the device is difficult to operate and causes more tissue damage in deep channel sutures
Solution Approach 1:
The suture device is divided into multiple functional segments: a puncture needle for creating the initial opening, a suture rod for delivering the suture material, and a push rod for advancing the suture rod. This segmentation allows each component to perform its specific function efficiently, reducing unnecessary tissue manipulation and damage while improving ease of operation in deep channel sutures
Solution Approach 2:
The suture rod acts as an intermediary component between the puncture needle and the suture material. It is pushed through the puncture needle's opening and carries the suture material through the deep channel, allowing the suture to be delivered without repeatedly shuttling the puncture needle through the tissue, thereby reducing tissue damage
2Productivity
If a traditional single needle suture device is used, then the suture needle can shuttle back and forth, but the operation becomes difficult and time-consuming for deep wounds
Solution Approach 1:
The puncture needle first creates an opening and positions itself in the deep channel before the suture rod is introduced. This preliminary action eliminates the need for repeated needle shuttling, allowing the suture material to be delivered through the pre-established pathway, thereby improving both productivity and ease of operation
Solution Approach 2:
The functions of needle shuttling and suture delivery are extracted into separate operations: the puncture needle creates the pathway and is then withdrawn, while the suture rod is pushed through the opening to deliver the suture. This separation eliminates the complexity of shuttling the needle back and forth through deep tissue, improving operational ease and efficiency

AI summary
It is provided a suture device for a deep channel, including a casing and a suture assembly. The suture assembly includes a suture hooking rod, a puncture needle, a first push needle and a second push needle. The suture hooking rod is of a hollow structure with two ends opened, a top end of the suture hooking rod is provided with a bending portion. The bending portion is inverted L-shaped, and a transverse portion of a top end of the bending portion is provided with a hole for the puncture needle to pass through. The puncture needle is of a hollow tubular structure with a top end opened, and a side of the puncture needle is further provided with a first opening. The puncture needle is arranged in the hollow structure of the suture hooking rod. The first push needle and the second push needle are both arranged in the hollow tubular structure of the puncture needle. The first push needle is configured to push the first suture rod, and the second push needle is configured to push the second suture rod. The present disclosure reduces difficulty of suturing operation, is conducive to recovery of the sutured wound and can also be used within a channel with a length of more than 300 mm.
