Become, clamps the body of rod.The section of elastic slice is in herringbone at this time.Second conveying assembly 24 drives knife bar 11 to move with respect to delivery section 20
Dynamic, bulb 110 is contradicted with 122 edge of diameter holes drives insulative head 12 to separate with delivery section 20.Insulative head 12 and delivery section 20
Between the body of rod formed IT knife.
It is the second embodiment of the utility model endoscope-use high-frequency therapeutic treatment device 100 please continue to refer to Fig. 7 to Fig. 8,
In the present embodiment, 100 structure of endoscope-use high-frequency therapeutic treatment device is roughly the same with first embodiment, and difference is: the first knot
Closing construction is not elastic slice, and the first combined structure is equipped with neck 136, two stopping plates 137 and clamping part 138.Neck 136 can become
Shape plays the role of being interference fitted with first embodiment small-and-middle diameter hole 122, and clamping part 138 plays elastic portion 133.It is swollen
The outer diameter in big portion 110 is greater than the spacing between stopping plate 137, prevents the excessively income delivery section 20 of bulb 110 from leading to insulative head
12 fall off.When using endoscope-use high-frequency therapeutic treatment device 100, referring to Fig. 8, the stage portion 220 and buckle of the first conveying assembly 22
The buckle of portion 138 keeps insulative head 12 and delivery section 20 fixed, applies preset second motivator to the second conveying assembly 24, pushes away it
Moving knife bar 11 is mobile to distal end relative to delivery section 20, and bulb 110 actuates to break through under power drive second matches with 136 interference of neck
The state of conjunction and stretch out in insulative head 12 formed needle knife.When needing endoscope-use high-frequency therapeutic treatment device 100 from needle knife-like state tune
When section to IT knife-like state, the second conveying assembly 24 drives knife bar 11 mobile to 20 proximal end of delivery section until bulb 110 crosses neck
Portion 136 enters insulative head 12, applies preset first motivator to the first conveying assembly 22 along flexible shroud 21, makes it to flexibility
Stage portion 220 is separated with clamping part 138 in 21 proximal end moving process of sheath, so that insulative head 12 and delivery section 20 are unlocked, then
Secondary distally to move the second conveying assembly 24 to flexible shroud 21, bulb 110 and neck 136 are interference fitted, and drive insulative head 12
It is separated with delivery section 20, the body of rod between insulative head 12 and delivery section 20 forms the work department of IT knife.When needing endoscope-use
When high-frequency therapeutic treatment device 100 is adjusted to needle knife-like state from IT knife-like state, insulative head 136 is drawn to delivery section 20 along flexible shroud 21
It is close to apply the first motivator to the first conveying assembly 22 up to abutting with delivery section 20, and then along flexible shroud 21, make its Xiang Rou
Property 21 distal end moving process of sheath in stage portion 220 and bayonet part 138 buckle, and then apply second to the second conveying assembly 24 and promote
Power makes it that knife bar 11 be pushed to move with respect to delivery section 20 to distal end, and bulb 110 actuates second and crosses neck under power drive
136, which stretch out insulative head 12, forms needle knife.It is pierced by guarantee that bulb 110 can smoothly cross neck 136 when being converted into needle knife
In insulative head 12, above-mentioned first motivator is greater than the second motivator.
It is the 3rd embodiment of the utility model endoscope-use high-frequency therapeutic treatment device 100 please continue to refer to Fig. 9 to Figure 10,
In the present embodiment, 100 structure of endoscope-use high-frequency therapeutic treatment device is roughly the same with second embodiment, and difference is: first
Combined structure does not have neck 136, and cutting part 10 includes elastic ring 14, and elastic ring 14 substitutes neck 136 and plays identical interference fit
Effect.
It is the fourth embodiment of the utility model endoscope-use high-frequency therapeutic treatment device 100 please continue to refer to Figure 11 to Figure 12,
In the present embodiment, 100 structure of endoscope-use high-frequency therapeutic treatment device is roughly the same with 3rd embodiment, and difference is: cutting
Portion 10 includes resilient sleeve 15.The effect of resilient sleeve 15 acts on identical with elastic ring 14.
It is the 5th embodiment of the utility model endoscope-use high-frequency therapeutic treatment device 100 please continue to refer to Figure 13 to Figure 14,
