Abstract
The utility model discloses a snare integrating cold and heat. The snare comprises a snare body, a pull cable connected with the snare body and a hand ring connected with the pull cable; the hand ring is fixed to a core rod; a limiting block is arranged at one end, close to the snare body, of the hand ring; a positioning cap is arranged at the front end of the core rod; an electric conduction plug which is electrically connected with the pull cable is arranged on the positioning cap; the snare body is formed by weaving sharp metal wires; the metal wires are coated with a color layer used for measuring the size of polyp. The snare can be used for polyp resection operation directly without energization. Compared with the traditional electric snare, the operation time is greatly reduced, and the risks of bleeding in an operation or post-operation delayed bleeding are reduced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind ofly can realize energising and no power carries out the cold-hot integrated snare of EMR (EMR) simultaneously.
Background technology
Endoscopic inferior mucosa excision (EMR), refers to the technical method that cuts bulk mucosal tissue after injectable drug forms liquid pad in focus (as sessile polyp, smooth or shallow depression type polyp, leiomyoma, esophagus, stomach, colon early cancer's etc.) tela submucosa.Its advantage is to operate on operation, can be by lesion resection under scope.
Traditional electric snare excision polyp, is often accompanied by perforation, art, postoperative hemorrhage and the patient's that burns risk.For anticoagulant therapy patient, carry out EMR operation and go to toward withdrawing anticoagulation.Because causing the histological examination of the polyp of excision, tissue ablation has obstruction, and one of basic principle of polypectomy is exactly, complete excision polyp is to provide sufficient histological examination, this point is when for small-sized polyp (≤9mm), and electric snare cannot meet the demands.
Utility model content
Utility model object: technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of snare of cold-hot integrated.
In order to solve the problems of the technologies described above, the utility model discloses a kind of snare of cold-hot integrated, comprise snare, connect the drag-line of snare, connect the bracelet of drag-line, bracelet is fixed on core bar, bracelet front end is provided with limited block, and core bar is provided with positioning cap near snare one end, and positioning cap is provided with the conductive plug that is electrically connected to drag-line, described snare is formed by sharp metal wire knitted, applies for measuring the color layers of polyp size on tinsel.
In this utility model, described snare is any one in ellipse, hexagon, semilune, rhombus and tear drop shape.
In this utility model, described zip is provided with epitheca pipe outward.Epitheca pipe is by the plastic tube of strengthening, or the bourdon tube of flexing design makes, and amount of contraction is little, for cutting provides maximum support.
In this utility model, described positioning cap is connected with the protecting pipe of covered section epitheca pipe towards snare one side.
Snare of the present utility model, can realize energising and no power excision polyp.The metal wire of snare has guaranteed the sharp of cutting.
Described snare is realized opening, withdraw, rotating of lasso by bracelet, limited block and core bar.
This utility model is the snare for a kind of cold-hot integrated of EMR design, on lasso with different colours labelling, be used for measuring polyp size, outside polyp exceeds mark line, can power-on servicing, can be used as traditional snare uses, when polyp is in labelling, polyp is less than 9mm, can directly carry out polypectomy hands art by no power, compare and greatly reduced operating time with traditional electrical snare, reduced intraoperative hemorrhage, and the hemorrhage risk of postoperative delay, the tissue that cold cut simultaneously removes can fully provide histological examination, also for carrying out polypectomy, anticoagulant therapy patient provides a kind of more effective method simultaneously.
This utility model beneficial effect is as follows: a. lasso carries measurement markers, can be according to Marker selection cold cut or fervent; While b. switching on, can be used as traditional snare and use; C. during cold cut, without energising, reduce the patient's that burns risk, operation time shortens; D. in art, at once go out insufficiency of blood; E. postoperatively postpone insufficiency of blood; F. without prophylactic postoperative clamp.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is done further and illustrated, above-mentioned and/or otherwise advantage of the present utility model will become apparent.
Fig. 1 is snare schematic diagram.
Fig. 2 is snare structural representation.
Fig. 3 is snare schematic cross-section.

The specific embodiment
Embodiment
Each Reference numeral implication of the present embodiment is as follows: 1: lasso; 2: drag-line; 3: epitheca pipe; 4: protecting pipe; 5: conductive plug 6: positioning cap; 7: limited block; 8: hands ring; 9 core bars.
As shown in Figure 1, Figure 2 and shown in Fig. 3, the present embodiment discloses a kind of snare of cold-hot integrated, comprise rhombus snare 1, connect the drag-line 2 of snare, connect the bracelet 8 of drag-line, bracelet 8 is fixed on core bar 9, bracelet 8 front ends are provided with limited block 7, and core bar 9 is provided with positioning cap 6 near snare one end, and positioning cap 6 is provided with the conductive plug 5 that is electrically connected to drag-line, described snare 1 is formed by two sharp metal wire knitted, applies for measuring the color layers of polyp size on tinsel.Described zip is provided with epitheca pipe 3 outward.Described positioning cap is connected with the protecting pipe 4 of covered section epitheca pipe towards snare one side.In Fig. 3, Lycoperdon polymorphum Vitt filling part is polyp tissue.
In the present embodiment, slide block 8 can slidably reciprocate on core bar 9, by drag-line 2, controls opening and withdrawing of lasso 1.Limited block 7, can be fixed on core bar 9 distance moving around for controlling slide block 8.Core bar 9 and positioning cap 6, for being slidably socketed, core bar 9 can be around its axial rotation, and drag-line 2 is synchronously steel wire rope or the monofilament of transmitting torque, transmits the moment of torsion of core bar 9 to lasso 1, can realize the synchronous rotary of lasso 1 and core bar 9.Conductive plug 5 contacts with drag-line 2, and drag-line 2 is connected with lasso 1, forms conductive path.
During use, under the auxiliary supervision effect of endoscope, mosquito forceps is transported to pathological changes assigned address, the conductive plug at handle place is connected to high frequency electric source, slide block recession, binding clip is closed, now can be used as high frequency incision knife and uses, and pathological tissues is carried out to labelling, cutting; If occur hemorrhagely in operation process, can advance handle place slide block, binding clip is opened rotate core bar to take the lead binding clip rotation simultaneously, now can be used as mosquito forceps and stopped blooding in hemorrhage place.The pathological tissues that also can gripping after having performed the operation goes out to cut down.
As shown in Fig. 4 a～Fig. 4 d, certain described snare can be also any one in ellipse, hexagon, semilune and tear drop shape from left to right in figure.
This utility model provides a kind of snare of cold-hot integrated; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; not departing under the prerequisite of this utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
