Abstract
The utility model provides an intestines and stomach mirror pincers way surgical instruments, including the pincers way that the sheath pipe constitutes, the sheath is intraductal to be equipped with an injection syringe and a metal seal wire along length direction, the end of injection syringe is equipped with hollow syringe needle, and the top of injection syringe links to each other with external syringe, metal seal wire top links to each other with external operating handle, and the end -to -end connection has metal snare ware, and metal snare ware is equipped with the sawtooth foremost.
Description
Technical field
This utility model relates to medical instruments field, especially a kind of Gastrointestinal Endoscopes pincers road operating theater instruments.
Background technology
Utilize Gastrointestinal Endoscopes pincers road, apply various special equipment, under Gastrointestinal Endoscopes direct cut-out gastrointestinal mucosa, be mesh
Before the Gastrointestinal Endoscopes Minimally Invasive Surgery the most extensively carried out.This operation is broadly divided into two classes.Obvious, in there being the base of a fruit to cease for protuberance
The focus that meat sample changes, can give coagulation TURP with its base of a fruit of electricity consumption snare direct snare；And for relatively flat disease
Stove, because electricity snare cannot entangle focus mucosa, then needs mucosa decollement (Endoscopic under row scope
Submucosal dissection, ESD).
But the operating difficulty of ESD art and operation risk are far longer than electricity snare excision.
Summary of the invention
Goal of the invention: the utility model proposes a kind of Gastrointestinal Endoscopes pincers road operating theater instruments, it is possible to use the method for electricity snare excision
Excise relatively flat focus so that it is avoid row ESD art.
Technical scheme: for realizing above-mentioned technique effect, the technical scheme that the utility model proposes is: a kind of Gastrointestinal Endoscopes pincers road
Operating theater instruments, the pincers road constituted including sheath pipe 1, it is provided with a syringe 2 and a metal in sheath pipe 1 along its length
Seal wire 3；The end of syringe 2 is provided with hollow needle 8, and the top of syringe 2 is connected with external syringe；Metal is led
Silk 3 tops are connected with external operation handle, and end connects has metal snare 6, metal snare 6 to be provided with saw foremost
Tooth 7.
Further, it is provided with sleeve pipe outside wire guide 3.
Beneficial effect: first this utility model is placed on outside smooth focus mucosa with the electric snare metal snare opened
In week, block focus far-end with the zigzag agnail that metal snare is most advanced and sophisticated, then by the entry needle of electricity snare root to glutinous
Film hemostasis physiological saline and so on liquid, makes focus mucosa protuberance, praises, enter in wire guide circle, tighten up metal simultaneously
Guide chase ring makes it entangle the focus mucosa of protuberance and be excised.
Endoscopic injection pin and electricity snare are all existing mature technologies, with scope entry needle to submucosal injection normal saline
Being excised after making focus mucosa protuberance Deng liquid, praise also is common practice again, in order in focus mucosa and basis set
Form liquid cushion between knitting, prevent the electric knife damage to deep tissues.But the mucosa protuberance that the injection of endoscopic injection pin causes is main
If uniformly swelling, smooth focus also is difficult to make electricity consumption snare excise after injection protuberance.
Entry needle and electricity snare are integrated into one structure by this utility model, are not the simple additions of two apparatuses, and
It is to achieve " first snare, afterwards injection ".First launch snare, and block focus with the zigzag agnail that snare is most advanced and sophisticated
Far-end, then inject cause smooth focus mucosa protuberance with the entry needle of snare root, enter in snare, finally tighten up,
Excision.
This utility model simple in construction, it is simple to realize, can solve smooth mucosa under Gastrointestinal Endoscopes by better simply mode part
Excision problem, simplify surgical procedure, reduce sufferer painful.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment mesotheca pipe internal structure schematic diagram；
Fig. 2 is the external structure schematic diagram that this utility model is implemented.
In figure: 1, sheath pipe, 2, syringe, 3, wire guide, 4, slide block, 5, slide rail, 6, metal snare,
7, sawtooth, 8, hollow needle.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described.
As Fig. 1 to 2 show a kind of embodiment of the present utility model, it includes: sheath pipe 1 and being connected with sheath pipe 1 top
Operation handle, operation handle is hollow structure, and operation handle outer wall is respectively provided on two sides with an injection nozzle 9 and along operation
The slide rail 5 that decreased food direction extends；A syringe 2 and a wire guide 3 it is provided with along its length in sheath pipe 1；
The end of syringe 2 is provided with hollow needle 8, the top of syringe 2 stretch out from injection nozzle 9 and with external syringe phase
Even；Wire guide 3 top connects a slide block 4, and slide block 4 and slide rail 5 form guide rail slide block structure, wire guide 3 end
End connection has metal snare 6, metal snare 6 end to be provided with zigzag agnail 7.
In use, comprise the steps:
(1) first sheath pipe 1 is stretched into patient's gastral cavity by the pincers road of gastroscope；
(2) slide block 4 on regulation operation handle, makes metal snare 6 stretch out from sheath pipe 1 end, launch, be placed on
Focus mucosa periphery, and block focus far-end with the zigzag agnail that metal snare is most advanced and sophisticated；
(3) external syringe stretches into from injection nozzle 9 top with syringe 2 to be connected, promote syringe 2 from
And make hollow needle 8 penetrate lesions position, inject medicament to lesions position and make focus protruding；
(4) retract syringe 2, make hollow needle 8 be retracted to sheath pipe 1；
(5) slide block 4 on regulation operation handle, tightens up metal snare 6 thus removal of lesions tissue.Because wire guide 3
The most mutually be wound around impact with syringe 2 and use function, for solving this problem, also include following preferably
Embodiment:
It is provided with sleeve pipe outside wire guide 3, by sleeve pipe, syringe 2 and wire guide 3 is isolated, form two operations
Passage.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
