Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the utility model overall schematic.

Fig. 2 is the utility model housing schematic diagram.

Fig. 3 is the utility model cone schematic diagram.

Fig. 4 is the utility model shell schematic diagram.

Specific embodiment

Attached drawing shows the specific structure of the preferred embodiment of the utility model, below will be to each element of the utility model Structure elaborate, direction (up, down, left, right, before and after) described below using structure shown in FIG. 1 as reference plane, this The actual use of utility model is without being limited thereto.

Embodiment one: as shown in Fig. 1-4, the utility model includes catheter body, seal wire, seal wire operator, the seal wire Operator includes housing 1, shell 2, cone 3, the housing 1, shell 2, cone 3 central axes be equipped with silk guide passage 4, it is described outer Set 1 is equipped with hollow cavity 101 in the left end of shell 2, housing 1, is equipped with spring 5 in the hollow cavity 101, the spring 5 is being bored The left end of body 3, the side of the cone 3 are set there are two corresponding through-hole 6, are equipped with ball 7 in each through-hole 6, in the shell 2 Equipped with conical hole 8 corresponding with cone 3.

Housing 1 and shell 2 are non-disconnectable connection and are equipped with certain stroke space between the two, and in original state, spring 5 is right The conical hole 8 of the elastic force very little of cone 3, shell 2 does not form pressure to ball 7, and at this moment the present apparatus can be moved on seal wire It is dynamic.In use, being fixed it with housing 1 with hand pressing shell 2, at this moment, spring 5 is compressed, and the elastic force of spring 5 makes cone 3 with the conical hole 8 of shell 2 closely close to conical hole 8 makes ball 7 carry out jam-packed to seal wire along through-hole 6.

Wherein, the hollow cavity 101 is the big pitcher of the small right mouth of left mouth.

Wherein, the left end of the cone 3 is equipped with limit fixed column 301.

Embodiment two: on the basis of above embodiments, as shown in Fig. 2-4, positioning gear is fixed on the shell 2 Block 9, the housing 1 is interior to be equipped with block channel 10, and the outer wall perforation of block channel 10 and housing 1 is equipped with first window 11 and second Window 12, the position block 9 include detent 901, and the detent 901 can stick into first window 11 and the second window In 12.

901 original state of detent is close in the second window 12, and after pressing shell 2 to the left, cone 3 is by bullet Spring 5 compresses, and at this moment, positions link stopper 9 along channel 10 and moves on to the second window 12 from first window 11, detent 901 is second It is close in window 12, position block 9 is made into for elastic resin material.

Embodiment three: on the basis of above embodiments, in order to recall shell 2, the housing 1 is equipped with press button 13, The press button 13 in the top of first window 11, the position block 9 is symmetrical above and below set there are two.Press the press button on housing 1 13,13 pressure positioning pawl 901 of press button disengages it from first window 11, and then shell 2 makes to position under the action of 5 elastic force of spring Pawl 901 returns in the second window 12.
