Description
Technical field
This utility model relates to a kind of easily rotation snare, belongs to medical instruments field.
Background technology
Snare is mainly used in coordinating under scope the excision of high-frequency electrical to various polyps and unnecessary tissue.In clinical use procedure, need to adjust snare direction according to lesions position, direction by swivel ferrule realizes, the common snare using clinically is at present difficult to reach the requirement of the even smooth and easy swivel ferrule of energy, main cause is that common Cable cannot meet the demands, Ye You company solves Rotation by the method that customizes special rotating wire rope, but cost is very high, is not suitable for the requirement of disposable use to economy.Therefore the snare of traditional structure is badly in need of improving.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of easily rotation snare is provided, and when it has avoided rotation, ferrule heads is beated and rotates the phenomenon having some setbacks, and rotate effect is good.
In order to solve the problems of the technologies described above, this utility model take technical scheme be: a kind of easily rotation snare, it comprises lasso, drag-line, outer tube, turncap, guide pipe, slip ring, electrode and hands handle, drag-line plug-in mounting within the outer tube, the tail end of outer tube is fixedly connected on turncap, and be connected to the head end of handle this turncap card slot type, slip ring sleeve be contained on handle and relatively handle move axially, guide pipe is inserted in handle, the tail end of guide pipe and electrode are fixedly connected on slip ring, and the tail end of guide pipe and electrode are electrically connected, described drag-line comprises flexible steel cable and titanium-nickel wire, one end of flexible steel cable is fixedly connected with the tail end of lasso, the other end is fixedly connected with one end of titanium-nickel wire, the other end of titanium-nickel wire is fixedly connected with the head end of guide pipe.
Further, on described flexible steel cable and the connecting portion of lasso, be set with the first connection tube, one end of described flexible steel cable is fixedly connected with the tail end of lasso by the first connection tube.
Further, on described flexible steel cable and the connecting portion of titanium-nickel wire, be set with the second connection tube, the other end of described flexible steel cable is fixedly connected with one end of titanium-nickel wire by the second connection tube.
Adopt after technique scheme, drag-line comprises flexible steel cable and titanium-nickel wire, the centre of flexible steel cable and titanium-nickel wire is fixedly connected with connection tube, the good titanium-nickel wire of rigidity can transmit larger transmission power, the rotational resistance that flexible steel cable causes can reduce ferrule heads bending time, adopt the structure of flexible steel cable and titanium-nickel wire combination, the head of lasso just can not produce the phenomenon of beating so when rotated, and rotate effect is good.
Brief description of the drawings
Fig. 1 is the structural representation of easy rotation snare of the present utility model;
Fig. 2 is the A portion stayed structure enlarged drawing of Fig. 1.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below.
As shown in Fig. 1 ~ Fig. 2, a kind of easily rotation snare, it comprises lasso 1, drag-line, outer tube 6, turncap 7, guide pipe 8, slip ring 9, electrode 10 and handle 11, drag-line is inserted in outer tube 6, the tail end of outer tube 6 is fixedly connected on turncap 7, and be connected to the head end of handle 11 these turncap 7 card slot types, slip ring 9 be sleeved on handle 11 and relatively handle 11 move axially, guide pipe 8 is inserted in handle 11, the tail end of guide pipe 8 and electrode 10 are fixedly connected on slip ring 9, and the tail end of guide pipe 8 and electrode 10 are electrically connected, described drag-line comprises flexible steel cable 3 and titanium-nickel wire 5, one end of flexible steel cable 3 is fixedly connected with the tail end of lasso 1, the other end is fixedly connected with one end of titanium-nickel wire 5, the other end of titanium-nickel wire 5 is fixedly connected with the head end of guide pipe 8.
As shown in Figure 2, on the connecting portion of flexible steel cable 3 and lasso 1, be set with the first connection tube 2, one end of flexible steel cable 3 is fixedly connected with the tail end of lasso 1 by the first connection tube 2; Flexible steel cable 3 is not limited to this with the connected mode of lasso 1, also can adopt butt-joint or other technique to connect.As shown in Figure 2, on the connecting portion of flexible steel cable 3 and titanium-nickel wire 5, be set with the second connection tube 4, the other end of flexible steel cable 3 is fixedly connected with one end of titanium-nickel wire 5 by the second connection tube 4; Flexible steel cable 3 is not limited to this with the connected mode of titanium-nickel wire 5, also can adopt butt-joint or other technique to connect.
The diameter of the diameter of flexible steel cable 3 and titanium-nickel wire 5 can unequally also can equate, wherein unequal situation can be: the diameter of the diameter of flexible steel cable 3 or flexible steel cable 3 larger than the diameter of titanium-nickel wire 5 than the diameter of titanium-nickel wire 5 is little can.
Operation principle of the present utility model is as follows:
When use, handle slip ring 9 and on handle 11, move axially forward and release lasso 1, in the time needing the direction of swivel ferrule 1, on the other hand fixing turncap 7, turning handle 11 on the other hand, be connected to the head end of handle 11 turncap 7 card slot types, lasso 1 is fixedly connected with flexible steel cable 3, flexible steel cable 3 is fixedly connected with titanium-nickel wire 5, titanium-nickel wire 5 is fixedly connected with guide pipe 8, guide pipe 8 is inserted in handle 11, guide pipe 8 is fixedly connected with and is fixed on electrode on slip ring 9, slip ring 9 be sleeved on handle 11 and relatively handle 11 move axially, so, turning handle 11 has just driven the rotation of lasso 1, the good titanium-nickel wire 5 of rigidity can transmit larger transmission power, the rotational resistance that flexible steel cable 3 causes can reduce lasso 1 head-bent time, so, the structure of employing flexible steel cable 3 and titanium-nickel wire 5 combinations, like this it when rotated the head of lasso 1 produce without jumping phenomena, rotate effect is good.
