The viewing hole of mountable endoscope.
Preferably, the expanding sheath in-core edge is axially arranged with attraction channel.
Preferably, seal wire or surgical instrument are operated by the operating walk way.
Preferably, the expanding sheath in-core edge is axially arranged with waterflood path.
Preferably, the epitheca is stretched out in expanding sheath core front end, the expanding sheath core front end is tapered.
Preferably, the expanding sheath core bendable front end.
Preferably, it is described it is outer it is intrathecal can be inserted into sheath, can be inserted into miniature kidney in the instrument channel which forms
Mirror.
Preferably, forming ring cavity between the interior sheath inner cavity and miniature kidney mirror, the ring cavity and setting are on the interior sheath
Water filling fittings.
Preferably, there are gap between the epitheca and interior sheath, the epitheca is equipped with suction tube, the suction tube and institute
State gap connection.
Preferably, the epitheca is equipped with suction device, which connect with the suction tube.
As can be known from the above technical solutions, the present invention, can be in visual state by the way of epitheca and the cooperation of expanding sheath core
The lower upper sheath operation for carrying out epitheca, to establish and expand operation path；Again using epitheca, the fit system of interior sheath and miniature kidney mirror
Rubble, clear stone are carried out by operation path, entire expansion, surgical procedure need to only use a kidney mirror, and under visibility status
It carries out, not only performs the operation at low cost, but also operation safety is reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of expanding sheath core in the present invention.
Fig. 2 is the A-A the schematic diagram of the section structure of Fig. 1.
Fig. 3 is the structural schematic diagram of epitheca of the invention.
Specific embodiment
The present invention is discussed in detail below with reference to Fig. 1, Fig. 2 and Fig. 3, illustrative examples of the invention and illustrates to use herein
Explain the present invention, but not as a limitation of the invention.
The present invention provides a kind of combined type ureterorenoscope, including epitheca 2, the outer intrathecal pluggable expanding sheath core 1, institutes
It states expanding sheath in-core and is provided in the axial direction with operating walk way 12, the built-in miniature kidney mirror of the operating walk way or seal wire etc., the expansion
Set in-core is provided in the axial direction with the viewing hole 13 of mountable endoscope.In implementation process, seal wire can be passed through to operating walk way, and
Guarantee that seal wire is guided under visibility status by endoscope and viewing hole, provides and clearly regard for the expansion of this set core
Open country, to complete the upper sheath operation of epitheca, the damage of ureter caused by avoiding because of blindmate.In addition, being built in operating walk way micro-
Type kidney mirror also can guarantee that upper sheath of the epitheca under visibility status operates using the lighting system of miniature kidney mirror.
In implementation process, the expanding sheath in-core is additionally provided with attraction channel 14 along axial direction, and thus forming triple channel can
Depending on expanding sheath core, the attractions such as waste liquid, slag can be come out by attraction channel, and operate seal wire under conditions of visual, safety
Effectively.Merging set core under conditions of visual simultaneously, so that more convenient operation, has saved operating time.The expanding sheath in-core
It is additionally provided with waterflood path 15 along axial direction, the clear visual field of visually upper sheath can be kept.Thus it then forms with independent waterflood path
The visual expanding sheath core of four-way, operate it is more convenient, time saving.The epitheca, the expansion are stretched out in expanding sheath core front end
It is tapered to cover core front end, facilitates the guiding expanding of expanding sheath core；And expanding sheath core bendable front end, that is, flexible material system can be used
At being further ensured that set core carries out safe and convenient expansion.
The surgical instruments such as miniature kidney mirror 3 can be used directly in the operating walk way of expanding sheath core of the invention, due to miniature kidney
Optical imagery lighting system is had on mirror, the cone cell front end of expanding sheath core can directly carry out guiding expansion, and optical imagery illuminates
System can provide sufficient illumination, be oriented to expanding sheath core precisely, to guarantee that cover core is expanded under the clearly visual field, is kept away
Exempt to damage ureter.In implementation process, when expanding sheath core is constantly expanded, epitheca takes out expansion also with ureter is protruded into
After covering core, then operation path is established, to facilitate the clear stone of rubble.The present invention is guaranteed using epitheca and the expanding sheath core of special designing
The accurate foundation and expansion of operation path, are greatly saved operating time, improve surgical procedure.
It is arranged with interior sheath 6 in epitheca of the invention, interior sheath inner cavity shaper tool channel can be inserted into miniature kidney in instrument channel
Mirror 3.After establishing operation path from outer intrathecal taking-up expanding sheath core, it is inserted into interior sheath, the instrument channel which forms
It is built in miniature kidney mirror to be operated, realizes the purpose of rubble, clear stone.In implementation process, the interior sheath inner cavity with it is micro-
Be formed with ring cavity 61 between type kidney mirror, i.e., in there is radial spacing between sheath inner cavity and miniature kidney mirror, including the ring cavity and setting
Water filling connector 4 on sheath is connected to, to fill the water by filling the water connector into ring cavity, the clarity of surgical field of view can be improved, reduce
The heat that Bladder stone generates reduces thermal damage and reduces the generation of postoperative complication.There are gaps between the epitheca and interior sheath
5, the epitheca is equipped with suction tube 7, which is connected to the gap, to pass through gap for rubble, waste residue, useless blood etc.
It is sucked out from suction tube, avoids the surgical procedure for influencing rubble kidney mirror.In implementation process, the epitheca is equipped with suction device
8, which connect with the suction tube, to adjust the size of the attraction of suction tube by suction device.Attract dress
Set such as cooperation of vacuum suction instrument, air bag and air compressor machine, air exhauster.
From the foregoing, it will be observed that the present invention realizes the upper sheath operation of epitheca by epitheca and expanding sheath core, to establish operation path, and
The purpose of rubble, clear stone is realized by epitheca, interior sheath and miniature kidney mirror；Since expanding sheath core is equipped with operating walk way, this is logical
It can directly be illuminated using miniature kidney mirror in road, place epitheca using seal wire guidance expanding sheath core with the prior art and more pacify
It is complete and effective；It saves a mark compared with the prior art is expanded placement epitheca, used rubble kidney mirror rubble using standard mirror
Quasi- mirror, so that cost be greatly saved.
Above embodiment is used for illustrative purposes only, and is not limitation of the present invention, related technical field
Those of ordinary skill without departing from the spirit and scope of the present invention can be with various changes can be made and modification, therefore institute
There is equivalent technical solution also to should belong to scope of the invention.
