Manufacturing and Analysis of Microsurgical Pen Needle Holder

Studies addressing the most fundamental surgical methods, like suturing or tying, are seldom ever found in the literature. The issues and effects of using needle holder equipment for extended periods of time are examined in this work. Within the manufacturing sector, 3D printing is growing in importance and promise. The industry for additive manufacturing currently anticipates producing a wide range of products shortly. The goal is to use finite element analysis for creating and simulating the new pen needle holder design. This work offers a novel method for improving surgical instrument design to help surgeons do procedures with greater comfort, accuracy, and reduced tremors. Pen Needle Holder was manufactured as part of the new modification process by 3D printing a metal version of the SOLIDWORKS 22 model. The mechanical ANSYS 22 program was used to carry out a number of computational simulations, and titanium was chosen as the material for the design parts. The safety factors of every junction are more than 1, as demonstrated by the numerical data (minimum 3.6842 − maximum 6.0185). Mechanically speaking, a safe model has a safety factor (safety factor = yield stress/working stress (unitless)) of at least 1. 176.91 MPa is the highest equivalent pressure that the model can produce. Those stresses are lower compared to the material's Young's modulus. Maximum equivalent strains generated from the produced stresses are acceptable (0.0018). Maximum resulted in deformations (0.78007 mm) that were barely seen. The results state the distribution of stress and total deformation on the new design to identify the regions of maximum stress and maximum deformation, representing the weak points. Finally, we prove that the geometrical pen needle holder surgical instrument is mechanically safe and usable for cases of tissue suturing in all needle orientations by simulation mechanical analysis of total deformation and equivalent stress and strain be all acceptable and appropriate.
