Abstract
The invention discloses an integrated device of an nasal endoscope, a washing tube and a negative pressure suction tube and an automatic system. The invention solves the technical difficulty that the nasal endoscope is separated from the flushing pipe and the negative pressure suction device, not only can keep the continuous and clear view field in the operation, but also effectively reduces unnecessary and complicated operations in the operation and improves the operation efficiency and the operation effect.
Description
Technical Field
The invention belongs to the technical field of medical instruments, relates to a conventional device, namely an endoscope, in the conventional operation and daily operation of an ear-nose-throat-head-neck surgery, and particularly relates to a simplified connection control device for organically integrating and integrating a nose endoscope lens, an endoscope body, a flushing pipe and a negative pressure suction device in the nose operation, and a multi-dimensional endoscope holding automation system in the nose endoscope operation.
Background
The nasal endoscope operation is one of the most common main operation modes of the ear-nose-throat department, and the nose lesion can be treated very finely by a matched surgical instrument, so that the operation can reach the region which can not be reached by the traditional operation. At present, the nasal endoscope is not only an effective means for treating the conventional nasal diseases, but also has important functions and significance in the field of lateral skull base operation. Meanwhile, the technology is not only limited to the operation of the ear-nose-throat department, but also widely applied to the preliminary diagnosis and treatment of the ear-nose-throat-head-neck surgical diseases and the postoperative review and evaluation.
At present, the nasal endoscope technology is developed more mature at home and abroad, and the used matched surgical instrument, namely the nasal endoscope, is a core hardware device component of the technology. The nasal endoscope is an optical hard tube endoscope capable of carrying out detailed examination on the nasal cavity, the diameter of a lens of the nasal endoscope is about 2.7-4mm, and the nasal endoscope can conveniently pass through the narrow nasal cavity and structures in a nasal passage to carry out examination on the nasal cavity and the nasopharynx part and even internal structures of paranasal sinuses. However, the device does not comprise the lens and the two functions of the irrigation and the negative pressure suction of the operation area, namely, the lens body, the lens, the irrigation tube and the negative pressure suction device of the nasal endoscope are not integrated but separated from each other. In the operation process, an operator often needs to hold a left hand mirror and a right hand to hold a washing tube or a negative pressure suction apparatus, and can complete the action of cleaning an operation area and clearing an operation field only by operating two hands simultaneously, if surgical instruments such as nasal cutting forceps and sieve opening forceps are needed to clean lesions, the operator needs to immediately withdraw from the negative pressure suction apparatus of the right hand and replace the surgical instruments for next operation, however, for some special diseases with large bleeding amount or deep lesion parts in the operation, the situation that the instruments are just replaced in the right hand and the operation area is immediately covered by blood or other special secretions often exists, and the operator often needs to replace the negative pressure suction apparatus and the surgical instruments again or even repeatedly to achieve the operation purpose as much as possible. Meanwhile, because the definition of the nasal endoscope head and the operation area greatly affects the visual field in the operation, when the lens is polluted by bloodstains or tissues in the operation, the nasal endoscope head must be withdrawn, the operation is continued after the operation is cleaned outside, or the operation area can be washed by the assistance of an operator, thereby increasing unnecessary complicated operation in the operation process, seriously affecting the operation efficiency and even the operation effect.
Meanwhile, the current nasal endoscope system can only be used for lighting and snooping a lesion area, still lacks an intelligent multi-dimensional management module based on the internet big data background, cannot perform high-quality reading, storage and integration on operation audio and video materials and related data materials, and further cannot perform corresponding adjustment and assistance aiming at different operation modes and different operation habits of operators.
In summary, the current nasal endoscope apparatus has the following disadvantages in the operation and examination process: (1) the surgical field definition in the surgical process is influenced, and the surgical difficulty is increased; (2) unnecessary and complicated operation actions are added for the operator, so that the operation time is prolonged, the related operation risks are increased, and the operation efficiency and even the operation effect are influenced to a certain degree; (3) it is difficult to realize the automatic collection and storage of the operation data, so that the related data lack the precise big data management, and the remote guidance, the operation teaching and the high-quality and detailed operation data reading, storage and integration can not be completed.
