Outer diameter 0.6mm, internal diameter 0.5mm, optical fiber are inserted into 28 internal diameter 2.0mm of fixed ring.
It should be noted that herein, " distal end " refers to instrument or member distance patient farther away one under use state
End, correspondingly, " proximal end " refers to instrument or the closer one end of member distance patient under use state.Present inventor is based on
Research experience abundant, invented it is a kind of video auxiliary anal fistula endoscope guide under deep fistula and cavity are examined
The new art formula looked into, while fistula wall and depth lesion are handled using laser equipment, and provided based on this of the invention
Video for Treatment of Anal Fistula assists endoscope set.It is performed the operation using methods and apparatus of the present invention row anal fistula, fistula is detected
With treatment can a step complete, no replacement is required in art instrument is easy to operate, saves the time.View for Treatment of Anal Fistula of the invention
Frequency auxiliary endoscope set is equipped with telescopic blade 32 and is hidden in cutter groove 31 when without using blade 32, is encountering
When fistula is narrow or adhesion, the i.e. extended blade 32 of the promotion of simple push-pull ring 24 operation can be passed through and cut adhesion group in fistula
It knits, further helps to detect complete fistula and internal orifice, improve procedure efficiency, it is very easy to use.The cutter groove, the quantity of blade
Preferably 2-8, more preferably 4-6, on the one hand there is enough blades effectively to cut to fistula adhesion part, on the other hand
Quantity is unlikely to excessive and causes entire instrument excessively complicated.The design of the fixing groove 231, spring 291, hoodle 292 makes knife
The flexible of piece 32 can be braked, and improve the stability of surgical procedure, and the design use it is very convenient.The stop collar
22 can further improve safety, prevent blade 32 from stretching out too long.The distal end end face of the epitheca 2 is the side of the i.e. tube wall of passivity
Edge track is arc, facilitates in art to strut fistula narrow positions, fast and easy is detected, and not injury tissue, avoids vacation
Road.The optical fiber insertion fixed ring 28 and fiber operation channel 27 cooperate, and help to improve the stability of optical fiber, are precisely grasped
Make, promotes surgical effect.Video auxiliary endoscope set for Treatment of Anal Fistula of the invention has the function of water filling and water suction,
The operation visual field can be made to become apparent from, avoid cardia from being not thorough, cause to remain, cause postoperative recurrence.The epitheca 2 may be designed to
Plurality of specifications, endoscope casing tube 21, fiber operation channel 27 and the optical fiber insertion fixed ring 28 of the epitheca 2 of different size can have
Different diameters, therefore can be selected according to the actual conditions of operation, the scope of application is wider, it helps obtains preferably treatment effect
Fruit.First fitting joint 12 and the second fitting joint 26 are preferably the threaded connection of the present embodiment, this kind of connection type is most
To be solid and reliable, but it is not limited only to this, can also be other dismountable fastening means.
Video auxiliary endoscope set due to the present invention for Treatment of Anal Fistula has the function of video direct-view, and laser fiber closes
Function is closed, and there is cutting function, no replacement is required in operating process instrument, fistula is detected and treated to carry out under direct-view, and can
One step is completed, and procedure efficiency is high, and effect is good, the treatment of clinically Complex Anal Fistula is therefore particularly suitable for, when reducing operation
Between, surgical effect is promoted, operating difficulty is reduced.
