Needle holders are utilized for which purpose?

1. To dissect tissues

2. To grasp and manipulate curved needles

3. To clean surgical instruments

4. To apply pressure to wounds

The correct answer is: To grasp and manipulate curved needles

Needle holders are specifically designed to grasp and manipulate curved needles during surgical procedures. Their primary function is to securely hold the needle while suturing tissues, ensuring precision and control during the stitching process. The design of needle holders often features a ratchet mechanism, which allows the user to lock the needle in place, providing stability and preventing the needle from slipping. This feature is crucial when a surgeon is operating on delicate or deep tissues, where accuracy is vital. In contrast, the other options present different tools or techniques. Dissecting tissues typically involves scissors or scalpels, which are designed for cutting rather than holding needles. Cleaning surgical instruments requires specific cleaning tools and solutions, not needle holders. Applying pressure to wounds is generally done using gauze or direct pressure with gloved hands, rather than with needle holders, which are not intended for this purpose. Therefore, the focus of needle holders is distinctly on their ability to manipulate needles effectively in surgical settings.
