Description

Open pull tab pliers

Technical Field

The utility model relates to medical equipment, in particular to an opening tongue pulling clamp.

Background

Currently, medical personnel are required to pull the front of the patient's tongue out of the mouth when examining the patient's mouth to prevent the patient's tongue from tampering with the patient's tongue and impeding handling and examination. The existing method is that medical staff wraps the tongue of a patient with gauze and pulls the tongue of the patient out of the oral cavity by hands, but the tongue of the patient is easy to slip, which is time-consuming and labor-consuming. In order to lighten the working intensity of medical staff, tongue forceps are developed later, and the medical staff can clamp the tongue of a patient out of the oral cavity easily by using the tongue forceps, but the patient is difficult to keep a large caliber of the mouth, the patient is easy to unconsciously shrink the caliber of the mouth, the operation and the examination of the medical staff are hindered, and the working efficiency of the medical staff is reduced.

The Chinese patent of CN207444920U, which is announced in 2018, 06 and 05, discloses a medical oral pull tab clamp, which comprises two handles, wherein the right ends of the two handles are rotationally connected through a pin shaft, the right ends of the two handles are respectively welded with a first clamp head and a second clamp head, clamping pieces are adhered to the first clamp head and the second clamp head, the clamping pieces are formed by equally distributing trapezoid protruding points and spherical protruding points, the right part of the handle is connected with a mouth gag through a supporting rod, the right end of the mouth gag is formed by splicing a first loop bar and a second loop bar, the right end of the second loop bar is welded with an arc-shaped support, and the end part of the arc-shaped support is welded with a tooth-shaped sleeve. The utility model can enable the patient to keep the mouth open with a larger caliber, so that the tongue of the patient can be easily clamped out of the oral cavity; but still has the disadvantages: the size of the opening device is fixed, medical staff breaks off the mouth of a patient first or actively opens the mouth of the patient, then plugs the opening device into the oral cavity, if the mouth of the patient opens to have smaller caliber, the opening device is not easy to plug, and the opening device is forced to plug, so that the patient feels uncomfortable.
