Textured Syringe Grip Assembly for Cystotome Capsulotomy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard syringe barrels lack ergonomic optimization and grip enhancement, making it difficult for practitioners to manipulate cystotomes during capsulotomies, especially during continuous curvilinear capsulorhexis procedures.
Innovation Solution
A syringe assembly with a grip featuring an elongated body having a textured outer surface and luer fittings for mounting a cystotome, providing enhanced grip and handling capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard syringe barrel is used, then the device structure remains simple, but the practitioner cannot grip or manipulate the cystotome effectively during capsulotomy
Solution Approach 1:
A grip component is introduced as an intermediary element between the syringe barrel and the cystotome hub. This grip includes a first female luer fitting that receives the syringe luer tip, and a second male luer fitting that receives the cystotome hub, thereby mediating the connection and providing an ergonomic gripping surface with textured outer surface for enhanced practitioner control.
2Ease of operation
If a smooth syringe barrel is used, then the manufacturing process is simple, but the practitioner lacks rotational control during continuous curvilinear capsulorhexis
Solution Approach 1:
The grip's outer surface is provided with a textured finish at the specific location where practitioner contact occurs, while the rest of the assembly maintains simple manufacturing. This localized texturing provides enhanced grip and rotational control during CCC procedures without complicating the overall manufacturing process of the syringe and cystotome components.

AI summary
In one aspect of the subject invention, a grip is provided for mounting to a syringe, the grip including: an elongated body extending along a longitudinal axis between first and second ends, the first end defining a female luer fitting configured for mounting onto the syringe, an inlet opening being defined in the female luer fitting, the second end defining a male luer fitting defining an outlet opening, and, a liquid passageway defined through the body between the inlet opening and the outlet opening to allow liquid flow therebetween. The body further defines an outer surface encircling the longitudinal axis, the outer surface being at least partially textured. Advantageously, with the subject invention, a grip is provided which is configured to both mount to a syringe and to mountingly receive a cystotome, in providing an enhanced gripping surface for a practitioner performing a capsulotomy.
