Abstract
This utility model relates to a kind of medical apparatus and instruments, especially a kind of Medical electric snare.A kind of Medical electric snare, comprise electricity circle, drag-line and core bar, described drag-line overcoat has pipe sheath, the end of described pipe sheath is connected with protecting pipe, described protecting pipe is connected with core bar by turncap, described core bar is provided with the slip ring slided along it, described slip ring is provided with electrode plug, described electrode plug and drag-line are electrically connected, described slip ring and core bar are provided with the finger-hole for finger manipulation, the inwall of described finger-hole is provided with encapsulate layer, the half-turn that described encapsulate layer touches with finger side grafting is evenly equipped with touch block, in addition half-turn has elastomer block.Increase encapsulate layer at the slip ring of finger manipulation use and the finger-hole inwall of core bar, increase comfort level when using and feel, half-turn tactile with finger side grafting on encapsulate layer is evenly equipped with touch block, in addition half-turn has elastomer block, prevent finger slippage, use more comfortable.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of Medical electric snare.
Background technology
Snare coordinates high-frequency electrical to the excision of various polyp and excess tissue under being mainly used in scope.The core bar of existing electric snare is set with the finger ring circle of slip, operate time, have the situation of finger slippage, and use feel and comfort level not good enough yet, the effect of operation can be affected.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides the Medical electric snare of a kind of comfort level when increasing use and feel.
This utility model solves the technical scheme that its technical problem adopts: a kind of Medical electric snare, comprise electricity circle, drag-line and core bar, described drag-line overcoat has pipe sheath, the end of described pipe sheath is connected with protecting pipe, described protecting pipe is connected with core bar by turncap, described core bar is provided with the slip ring slided along it, described slip ring is provided with electrode plug, described electrode plug and drag-line are electrically connected, described slip ring and core bar are provided with the finger-hole for finger manipulation, the inwall of described finger-hole is provided with encapsulate layer, the half-turn that described encapsulate layer touches with finger side grafting is evenly equipped with touch block, in addition half-turn has elastomer block.
Further, described touch block is convex dot shape structure, and described elastomer block is trapezoidal shape structure.The touch block of convex dot shape structure can increase friction, and the elastomer block of trapezoidal shape structure has certain damping action, jointly plays anti-skidding object.
The beneficial effects of the utility model are: increase encapsulate layer at the slip ring of finger manipulation use and the finger-hole inwall of core bar, increase comfort level when using and feel, the half-turn that encapsulate layer touches with finger side grafting is evenly equipped with touch block, in addition half-turn has elastomer block, prevent finger slippage, use more comfortable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
In figure: 1. electricity circle, 2. pipe sheath, 3. drag-line, 4. protecting pipe, 5. turncap, 6. slip ring, 7. core bar, 8. electrode plug, 9. encapsulate layer, 10. finger-hole, 11. touch block, 12. elastomer block.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Fig. 1 ~ Fig. 2, a kind of Medical electric snare, comprise electricity circle 1, drag-line 3 and core bar 7, drag-line 3 overcoat has pipe sheath 2, the end of pipe sheath 2 is connected with protecting pipe 4, protecting pipe 4 is connected with core bar 7 by turncap 5, core bar 7 is provided with the slip ring 6 slided along it, slip ring 6 is provided with electrode plug 8, electrode plug 8 and drag-line 3 are electrically connected, and slip ring 6 and core bar 7 are provided with the finger-hole 10 for finger manipulation, and the inwall of finger-hole 10 is provided with encapsulate layer 9, the half-turn that encapsulate layer 9 touches with finger side grafting is evenly equipped with and touches block 11, half-turn has elastomer block 12 in addition.
Further, touching block 11 is convex dot shape structure, and elastomer block 12 is trapezoidal shape structure.The touch block 11 of convex dot shape structure can increase friction, and the elastomer block 12 of trapezoidal shape structure has certain damping action, jointly plays anti-skidding object.
When excision polyp or excess tissue, pipe sheath 2 is input to the affected site in human body through endoscopic forceps channel, when core bar 7 moves forward slip ring 6 relatively, the front end from pipe sheath 2 is stretched out by electricity circle 1, and automatically form lasso, by endoscopic views, electricity circle 1 is enclosed within polyp or excess tissue, more gradually slip ring 6 is moved backward relative to mandrel 7, lasso diminishes thereupon gradually, polyp or excess tissue until be locked, then enclose 1 electrified regulation by electricity, makes polyp or excess tissue be solidified excision from normal structure.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
