Description

Oral cavity anesthesia mouth gag

Technical Field

The utility model relates to the field of medical instruments, in particular to an oral cavity anesthesia mouth gag.

Background

The traditional oral anesthesia mouth gag, also called mouth gag, is an instrument for expanding the oral cavity when dyspnea, tonsil operation or patient's mind is not clear and need gastric lavage. Is suitable for coma, special examination of opening mouth and choking caused by respiratory tract obstruction, and can open the upper and lower jaws of the patient with closed teeth in emergency. The existing oral cavity anesthesia mouth gag is U-shaped, and two ends of the mouth gag body are fixedly connected with a handle respectively. The opening device body has elasticity, and two side arms of opening device body can be to inside or outside the bending of opening device body when receiving the oppression by external pressure, when external pressure disappears, two side arms of opening device body resume original position again.

However, there are still some disadvantages of the current oral anesthesia mouth gag, for example, chinese patent literature (CN 210055958U) discloses an oral anesthesia mouth gag, including the supporting seat, the supporting seat groove has been seted up to the inside of supporting seat, the equal swing joint in both ends in supporting seat groove has the guide rail, the guide rail groove has been seted up to the inside of guide rail, the inside in guide rail groove is equipped with the pillar, both ends and the supporting seat groove fixed connection of pillar, the upper end fixedly connected with opening arm of guide rail, the one end outside that the opening arm kept away from the guide rail has cup jointed the protective sheath, one side upper end fixedly connected with opening fender arm of protective sheath, one side upper end fixedly connected with anticreep barb that the opening fender arm kept away from the protective sheath, the inboard of opening arm is equipped with the LED lamp.

Because the oral cavity anesthesia mouth gag generally adopts a half-opening structure, the mouth gag can not be conveniently and safely kept in an opening state by a patient. After the patient opens, only the limiting device is arranged, the opening degree can not be freely adjusted, the locking device is not arranged, the opening state can not be stably maintained, and the tongue pressing drag hook can not be freely replaced according to the age and the size of the patient. The infant patient uses chest support frame panel to fix, crushes the thorax easily without design use support frame panel and support post, pulls open-ended size state through hand power simultaneously, has both hard and easily drops and causes the secondary injury to the patient. In addition, in use, the tongue body, the tracheal catheter and the anesthetic tube are pressed to the other side through the tongue pressing drag hook, and when one side operation is finished, the positions of the tongue pressing drag hook and the tracheal catheter are adjusted to expose the tonsils at the other side, so that the operation time is prolonged, unnecessary repeated traction operation of oropharyngeal tissues is increased, postoperative pain and uncomfortable feeling of a patient are aggravated, the risks of shifting and slipping of the tracheal catheter are increased, and the patient cannot be effectively protected.

The uvula palatopharyngectomy is a common operation for treating obstructive sleep apnea and snoring, and the excision of part of uvula, tonsils and part of soft palate can enlarge pharyngeal cavity and reduce upper respiratory resistance during sleep, improving ventilation. The existing oral anesthesia mouth gag especially lacks a device for pulling the small tongue of a patient, and when the small tongue is operated, the pulling is realized by means of an additional pulling device, so that the operation is not easy to carry out.
