Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It is a kind of that cutting pipe is attracted to include with reference to Fig. 1-2 and Fig. 4-5：Outer tube 1, inner core 2, pushing hands 3.Wherein, outer tube 1
One end be equipped with for gripping handle 11 and for connecting aspirator（It is not shown）Connector 12, the other end be equipped with dedolation
Mouth 13, pushing hands 3 are mounted on outer tube 1, are arranged in the front of handle 11, and can be along predefined paths compared with the housing
Slidably, inner core 2 includes cutter head 21 and core main body 22 to pipe, and core main body 22 is equipped with connecting hole 23, and the plug-in unit in pushing hands 3 can be embedding
Enter into 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, inner core 2 is driven to transport
It is dynamic, excision operation is performed by cutter head 21.
It is to be understood that the predefined paths can be the predetermined stroke of the inner core when performing resection operation, 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 slot opened up on outer tube, make pushing hands can be with
It is moved in slot.Pushing hands 3 answers personnel easy to operation being capable of a hand operation compared with the distance of handle 11.
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
It it is 45 ° in the angle that face and horizontal plane are formed.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 aspirator, wait and being cut off by cutter head 21.
With reference to Fig. 3, upper backstop is equipped at the upper limb of beveling opening 13 along 131, in the case where the lower edge of beveling opening is equipped with
Along 132, upper and lower backstop is open preferably at grade backstop along with the beveling.Advantageously, above and below beveling opening
Backstop is set to cause undesirable injury to patient along that can prevent the cutter head of inner core from unintentionally stretching out outer tube at edge.
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.By this method so that lower backstop, can be with when running into softer tissue in being operated in excision along can have certain hardness
Play the role of removing 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, inhale at this time
Draw cutting pipe to function as a probe.

Movement and move, for moving forward when closes the gas vent, and the gas vent is opened in initial position.Here,
Initial position refers to that pushing hands is in the position of its rearmost end.In addition, inner core replacement port is also provided on outer tube 1, it is interior
Core is nested by the inner core replacement port in outer tube, is dismounted in order to the replacement of inner core.
One side according to the present utility model, connector 12 is stepped in becoming narrow gradually, for more firmly connecting
Connecting tube on aspirator.
The attraction cutting pipe for describing an embodiment of the utility model 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 treated at resection organization, will treat that resection organization is contained in
It in the beveling opening for attracting cutting pipe, places it in outer tube, promotes pushing hands forward, drive inner core movement so that inner core
Cutter head travels forward, while the catch connected in pushing hands moves forward, and the gas vent on outer tube is closed, at this point, in outer tube
By aspirator provide suction increase, tissue to be cut off further is attracted in outer tube, continues to press on pushing hands, makes knife
Head is further mobile, and resection organization is treated in final excision, and for closed state, suction is maximum for beveling opening and gas vent at this time,
After the completion of excision, need to provide larger suction or smaller suction determines according to actual conditions, it is larger when needing to provide
It during suction, then maintains vent closure state, when needing to provide smaller suction, then pull back pushing hands, baffle is made to open row
Stomata, to reduce the suction in outer tube.
In the above-described embodiment, cutting is attracted to manage substantially horizontal, another aspect according to the present utility model, inhaled
It can be the angled bend pipe of tool to draw cutting pipe, as shown in Figure 6.
Moreover, it will be appreciated that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
