J.M.S.W.S Type Uterine Dilator 7mm, Fig.7

Clinical Application

Designed to provide controlled cervical and uterine dilation, this 7 mm dilator is used to create and maintain a predictable working channel for intrauterine procedures. Common applications include preparation for hysteroscopy, insertion of intrauterine devices, endometrial biopsy, dilation prior to curettage, and other diagnostic or operative gynecologic interventions. The 7 mm diameter corresponds to a moderate dilation step in progressive dilator sets and is typically used in sequence with smaller and larger diameters to achieve desired cervical access with minimal trauma.

Design & Configuration

The straight, single-ended geometry with a tapered, smooth tip facilitates atraumatic entry through the cervical canal while allowing the operator to feel tissue resistance and control dilation progression. A dedicated grip area at the proximal end supports secure manual control and gentle advancement or withdrawal. The uniform cylindrical shaft provides consistent diameter along its working length, enabling predictable sizing when used in a serial dilation protocol.
