Nasal mucosal protective device for endoscopic sinus surgery passage

Abstract

The invention discloses a nasal mucosal protective device for an endoscopic sinus surgery passage; the protective device is surrounded by a nylon textile layer; a passage is formed at the interior after the nylon textile layer surrounding; one end of the passage is a stretching-out end, and the other end of the passage is a stretching-in end. The device also includes an air bag used for supportinga nasal cavity opening and arranged between the stretching-out end and the stretching-in end. The device can effectively protect mucosa of the inner wall of a nasal cavity by putting the device in the nasal cavity in advance, and unnecessary damage to the mucosa of the nasal cavity and a normal anatomical structure caused by the repeated access of an instrument in the operation process is avoided; moreover, the device can well adapt to the environment in the nasal cavity, even if the instrument impacts on the nasal passage, the device can also well decompose the impact force, and plays a highprotection effect on the inner wall of the nasal cavity. At the same time, even if a small amount of bleeding blood exists in the nasal cavity mucosa, through a self-woven dense mesh structure of theprotective device, the protective device can prevent the bleeding blood from flowing to an operation region of the bottom of the nasal cavity, maintains clearness of an operation field and an endoscopy lens, greatly saves the operation time, increases the safety of operation and reduces the risk of operation.

Description

technical field [0001] The invention belongs to the technical field of instruments for minimally invasive surgery, and in particular relates to a nasal mucosa protection device for a transnasal endoscopic surgery channel. Background technique [0002] With the continuous improvement of medical technology, more and more minimally invasive surgery has been applied in clinical practice, and achieved very good results. Minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. Minimally invasive surgery also reduces the damage to the human body caused by traditional surgery, and greatly reduces the inconvenience and pain caused to patients during the treatment of diseases. Therefore, the degree of acceptance of patients High, good satisfaction rate. In minimally invasive surgery, transnasal endoscopic surgery is a commonly used method in neurosurgery. It can fully expose and maximize the removal of diseased tissues at the base of the skull by ...

AI Technical Summary

Problems solved by technology

However, there are still some problems in transnasal surgery. Transnasal surgery is equivalent to using the nasal cavity as a passage for surgical instruments. Because the nasal passage is narrow and there are turbinates, nasal septum and other physiological and anatomical structures inside, it is very easy to appear when instruments repeatedly enter and exit the nasal cavity. During the process, collisions and damages are caused to the mucous membrane of the inner wall of the nasal cavity, and the mucous membrane of the inner wall of the nasal cavity is very fragile and delicate, and has a rich blood supply. Accidental injury will inevitably cause damage and bleeding of the mucous membrane, which is not only unnecessary harm to the patient, but also Moreover, the bleeding of the mucous membrane on the inner wall of the nasal cavity will cause repeated pollution of the neuroendoscopic lens, resulting in unclear vision, interfering with the surgical process, and increasing the risk of surgery
