Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. Pistol-type nasopharyngeal and laryngoscope, it has an endoscope (5), and the endoscope (5) is inserted in the mirror slot (11) of the bracket, and the bracket is managed by (1) and integrated with it Linked handles (15) form. A sharp point (3) extends obliquely forward and upward from the end of the trusteeship. The pointed tip (3) is used to raise the uvula upwards, so as to observe the nasopharynx and throat tissues covered by the uvula. The length of the tube of the trusteeship (1) is slightly shorter than the full length of the endoscope (5), the two are parallel to each other and the starting ends are aligned up and down. Therefore the endoscope (5) end exposes a small section in the mirror slot (11), and the exposed length can be set as about 5mm. After the optical fiber fitting (7) of the endoscope (5) is connected with the optical fiber tubes of other auxilia...

Abstract

The invention relates to a pistol sight glass for nasopharynx and larynx, which is medically used for inwardly observing the nasopharynx and the larynx of a patient through the opened oral cavity thereof. The sight glass is provided with an endoscope (5), and is characterized in that the endoscope (5) is inserted in an endoscope channel hole (11) of a supporting seat; the supporting seat comprises a supporting tube (1) and a handle (15) integrally connected with the supporting tube (1); a picking point (3) is upwards and slantwise extended from the operational end of the supporting tube (1); the supporting tube (1) is a little shorter than the full length of the endoscope (5) and is parallel to the endoscope (5), and the starting ends of the supporting tube (1) and the endoscope (5) are aligned with each other up and down; and the starting end of the cavity in the supporting tube (1) is a bell-mouthed supporting tube view-finder (13). The invention has the advantages of tight combination of endoscope and supporting tube; stable handling, more natural tube peep under the application of two observation windows, wider field of vision, and the like.

Description

technical field [0001] The invention relates to a pistol-type nasopharynx and laryngoscope, which is used in medicine to observe the nasopharynx or laryngeal cavity from the patient's open mouth. Background technique [0002] To peek at the nasopharynx and throat, the method is to insert the fiber optic tube of the endoscope from the nostril to a depth of nearly 7 cm. Find lesion, use biopsy forceps instrument to enter from oral cavity and cut living tissue on lesion very inconvenient. Currently, there are no nasopharyngeal and laryngoscopes that observe from the mouth inward. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, to provide a kind of handgun type nasopharynx and laryngoscope that are convenient to observe inwardly from the oral cavity and for biopsy forceps to pass through and bite the living tissue. [0004] The object of the present invention can be achieved like this: p...
