Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Reference picture 1-2 and Fig. 4-5, one kind attraction cutting pipe include：Outer tube 1, inner core 2, pushing hands 3.Wherein, outer tube 1
One end be provided with for grip handle 11 and for connecting attractor（It is not shown）Connector 12, the other end is provided with dedolation
Mouth 13, pushing hands 3 is arranged on outer tube 1, is arranged in the front of handle 11, and can be along predefined paths relative to the overcoat
Slidably, inner core 2 includes cutter head 21 and core main body 22 to pipe, and core main body 22 is provided with connecting hole 23, and the plug-in unit in pushing hands 3 can be embedding
Enter in connecting hole 23 so that inner core 2 is fixedly attached in pushing hands 3, when promoting pushing hands 3 so as to operating personnel, drive inner core 2 to transport
It is dynamic, excision operation is performed by cutter head 21.
It should be understood that the predefined paths can be the predetermined stroke of the inner core when resection operation is performed, pushing hands is along the predetermined road
Footpath is moved, so that inner core is moved according to predetermined stroke.The predefined paths can be the groove opened up on outer tube, make the pushing hands can be with
Moved in groove.Pushing hands 3 relative to the distance of handle 11 should be easy to operating personnel can hand operate.
Preferably, 13 place faces of opening are chamfer with the angle of horizontal plane formation in the range of 20 ° -70 °, it is further preferable that
The angle that beveling 13 place faces of opening are formed with horizontal plane is in the range of 30 ° -60 °.In the present embodiment, 13 institutes of beveling opening
The angle formed in face and horizontal plane is 45 °.The maximum outside diameter of the beveling opening is no more than 2mm, for by nasal cavity or ear chamber
In polyp or paraphyte accommodate wherein, under the cooperation of attractor, wait cut off by cutter head 21.
Reference picture 3, is provided with backstop along 131, in the case where the lower edge of beveling opening is provided with the upper limb of beveling opening 13
, along 132, upper and lower backstop is along with the beveling opening preferably at grade for backstop.Advantageously, in the upper and lower of beveling opening
Backstop is set at edge along that can prevent the cutter head of inner core from inadvertently stretching out outer tube, undesirable injury is caused to patient.
In addition, lower backstop along 132 length preferably in the range of 0.5-1mm, wall thickness is preferably in 0.5-1mm scopes
It is interior.In this way so that lower backstop along can have certain hardness, when can be with when softer tissue is run into cutting off operation
Play a part of to peel off tissue.
Furthermore it is also possible to be provided with sensor along place in lower backstop, for detecting the situation in ear chamber or nasal cavity, now inhale
Draw cutting pipe to function as a probe.
According to an aspect of the present invention, steam vent 14 is provided with outer tube 1, and one is connected with pushing hands 3
Catch, steam vent 14 is arranged in the front of pushing hands 3（Referring to Fig. 2）, the inwall of the catch laminating outer tube, with the shifting of pushing hands
Moving and move, the steam vent is closed during for moving forward, the steam vent is opened in initial position.Here, initial
Position refers to the position that pushing hands is in its rearmost end.Additionally, being also provided with inner core replacement port on outer tube 1, inner core leads to
Cross the inner core replacement port to be nested into outer tube, the replacing in order to inner core is dismounted.
According to an aspect of the present invention, connector 12 is stepped in what is become narrow gradually, for more firmly connecting attraction
Connecting tube on device.
The attraction cutting pipe for describing one embodiment of the invention below performs the operation principle cut off when operating.
When needing to perform excision operation, cutting pipe will be attracted to be placed in and to be treated at resection organization, will treat that resection organization is contained in
Attract in the beveling opening of cutting pipe, place it in outer tube, pushing hands is promoted forward, drive inner core motion so that inner core
Cutter head travels forward, while the catch connected in pushing hands is moved forward, the steam vent closed on outer tube, now, in outer tube
By attractor provide suction increase, tissue to be cut off further is attracted in outer tube, continue to press on pushing hands, make knife
Head is further mobile, and resection organization is treated in final excision, and now beveling opening and steam vent are for closed mode, and suction is maximum,
After the completion of excision, determined to need to provide larger suction or less suction according to actual conditions, when needing, offer is larger
During suction, then vent closure state is maintained, when needing to provide less suction, then pull back pushing hands, baffle plate is opened row
Stomata, to reduce the suction in outer tube.
In the above-described embodiment, attract cutting pipe substantially horizontal, according to another aspect of the present invention, attract to cut
Pipe cutting can be the angled bend pipe of tool, as shown in Figure 6.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
