example 1

[0037] see figure 1 , which is a schematic structural diagram of the endoscope 10 involved in this example. As can be seen from the figure, the endoscope 10 mainly includes a front base 11 and a front insertion part 12 arranged on the front base 11 in terms of composition.

[0038] The ear endoscope 10 with such a structure does not have a flushing and suction function, and it needs to cooperate with other instruments to perform operations such as cutting, peeling, and grinding, and to perform different operations such as sucking blood, flushing wounds, and sucking liquid tissues. The operator (for example: a doctor) only holds the instrument with one hand behind the endoscope, and the operating space is very limited, causing the operator to change various operating instruments back and forth.

[0039] For this endoscope 10, this example presents a solution of an externally-mounted flushing tube 20, which is hung outside the insertion part 12 of the endoscope 10 in a disposab...

example 2

[0073] This example provides a disposable flushing pipe 20 with an external hanging structure on the basis of the scheme of Example 1. Unlike the fixed setting of the flushing pipe in Example 1, the flushing pipe in this example scheme can be telescopically operated, which can further improve its performance.

[0074] see Figure 4 , which shows an example of the composition of the externally-mounted flushing pipe with a telescopic structure given in this example.

[0075] It can be seen from the figure that the composition structure of the external hanging suction pipe 20 mainly includes a connection base 21, a sleeve 22, a suction pipe assembly 23, a coupling part 24, a driving part 25, a connecting pipe and a control valve assembly (not shown in the figure) .

[0076] The basic structure and function of the connection base 21 in this example are the same as those in Example 1. It is used as the base part of the whole external flushing pipe 20 for connecting other componen...

Abstract

The invention discloses an external hanging type flushing and sucking pipe for an endoscope, and the endoscope. According to the invention, a flushing and sucking pipe assembly in the external hangingtype flushing and sucking pipe is connected with a base at the front end of the endoscope through a detachable structure and can be distributed on the outer side of an insertion part at the front endof the endoscope in the length direction of the insertion part at the front end of the endoscope; and according to the scheme provided by the invention, the inertia design thinking that a fixed structure needs to be adopted for guaranteeing the reliability of a product in the existing endoscope front-end function improvement scheme is abandoned, a reverse design scheme is innovatively adopted toform a disposable flushing and sucking pipe scheme externally hung on the endoscope, so that the endoscope has a flushing and sucking function under the conditions that the endoscope is not changed orimproved and the original function or performance of the endoscope is not influenced, and the convenience of endoscopic surgery operation is greatly improved.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an endoscopic instrument technology. Background technique [0002] The endoscope can enter the human body through the natural orifice of the human body, or a small incision made by surgery. Based on this, the minimally invasive surgery using the endoscope, because the patient has less trauma, lower surgical risk, faster postoperative recovery, and less impact on the appearance of the wound. Small and many other features have been widely valued and developed in various surgical fields in recent years. For example, ear endoscopic surgery has made important progress in many applicable diseases such as cholesteatoma and otitis media, and has been widely used. [0003] As we all know, one of the major constraints of ear endoscopic surgery is that the ear canal is generally only 4 to 5 cm in diameter, the operating space is very limited, and the doctor's hands are very crowded. For different o...
