Description

Intraoperative esophageal ultrasound mouth gag

Technical Field

The utility model relates to a middle-course of art esophagus is seaming ware for supersound belongs to medical instrument technical field.

Background

Transesophageal ultrasound has been used extensively in surgery for the last decade, particularly in cardiac surgery, and has significant implications for pre-operative diagnosis, intra-operative monitoring of cardiac function, and assessment of the outcome of surgery. When transesophageal ultrasound is used, a mouthpiece is conventionally used which is used to protect the patient's teeth and lips on the one hand and the esophageal ultrasound probe on the other hand to prevent the teeth from biting the probe.

Present seaming ware is mostly general type, can be used to through esophagus supersound, gastroscope inspection, fiberbronchoscope inspection etc. this kind of general type seaming ware is wider, has occupied most space between the upper and lower tooth, has inserted trachea cannula in the patient's oral cavity in the operation, causes to place the mouth gag more difficult, can prop oral cavity opening degree very big usually, harms lip of a mouth and gum mucosa easily, still has the possibility of bumping off the tooth to the patient that has the tooth to become flexible. The universal mouthpiece is integrated, when in use, the mouthpiece is sleeved into the esophagus ultrasonic probe, and the mouthpiece is placed after the esophagus ultrasonic probe is inserted into the esophagus, so that the mouthpiece cannot be placed if the esophagus ultrasonic probe is inserted first.

Retrieval and query of the current state of the art, application number: 201620499849.2 discloses a side-open type intraoperative esophageal ultrasound bite block, which comprises an occlusion tube, wherein an opening is arranged on the tube wall of the occlusion tube along the axis direction, one end of the occlusion tube is connected with a baffle, the baffle is also provided with a dividing line corresponding to the opening of the occlusion tube, and the baffle is divided into an upper baffle and a lower baffle by the dividing line.

The lip protecting plate integrated with the occlusion tube is a rectangle which is long up and down and narrow left and right, and mainly aims to press close to and protect the upper lip and the lower lip, and the left and right narrow design reduces the extrusion with the trachea cannula in the oral cavity and reduces the stretching damage to the lips and the corners of the mouth. The raised lip at the inside end of the bite tube serves to prevent the occluder from falling out of the mouth.

The smooth design of the whole edge of the articulator increases the comfort of use and prevents the damage to the oral mucosa. The round holes are arranged on the inner sides of the four round corners of the lip protecting plate, so that the connection between the two bite plates can be reinforced as required, and the bite device can be fixed behind the neck of a patient.

The utility model discloses no matter be shape design or concatenation mode all simple and novel, form by two identical snap-in boards splicing combination, the requirement to production technology is greatly simplified. The material may be resin or plastic, and it is preferable that the material has sufficient hardness and is slightly flexible. Can be used as a disposable product, which has a plurality of advantages for medical consumables used in the oral cavity.
