While the \u003cspan class=\"keyword-focus\"\u003euterine sound\u003c\/span\u003e measures depth, a dilator (like a Hegar or Pratt) is used to physically widen the cervical canal. Sometimes, a graduated dilator is used for \"sounding,\" but a dedicated \u003cspan class=\"keyword-focus\"\u003euterine sound\u003c\/span\u003e is thinner and safer for initial exploration.\u003c\/p\u003e\n\u003cp style=\"margin-top: 10px;\"\u003e\u003cstrong\u003eWhat is the use of uterine sound forceps?\u003c\/strong\u003e This is often a misnomer in clinical settings. Forceps (such as tenaculum forceps) are used to grasp and stabilize the cervix, whereas the \u003cspan class=\"keyword-focus\"\u003euterine sound\u003c\/span\u003e is used to enter the cavity. The tenaculum and the \u003cspan class=\"keyword-focus\"\u003euterine sound instrument\u003c\/span\u003e work in tandem: the forceps provide traction to straighten the cervical-uterine angle, facilitating the smooth entry of the sound.\u003c\/p\u003e\n\u003cdiv class=\"warning-hover\"\u003eSAFETY WARNING: Never use a uterine sound to attempt dilation of a stenotic cervix.
