It is arranged in the first regulating tank 112, to be abutted at different locations with the first locating part 161.
Specifically, as shown in figure 3, at this point, the limiting section 162b of the second locating part 162 is on the top of the first regulating tank 112
It is abutted with the first locating part 161, at this point, rotary-cut needle core 141 extend out to the length longest in 121 outside of needle tubing, so that
The vacuum suction rotary-cut aspiration needle 100 enter most deep lesions position, at the position sphacelus and separate floccule into
Row rotary-cut is smashed to pieces.Conversely, when not needing rotary-cut needle core 141 and stretching out length as shown in Figure 3, at this point it is possible to manipulate mounting portion
(for example, first is adjusted at suitable position required for 162a drives limiting section 162b to be moved downward to along the first regulating tank 112
At the medium position of slot 112), at this point, operator can move down 140 entirety of rotary-cut needle core component until the first locating part
161 abut with limiting section 162b, at this point, rotary-cut needle core 141, which just has, is different from extension elongation shown in Fig. 3.
The vacuum suction rotary-cut aspiration needle 100 of the present embodiment, can be by the first set locating part 161 and the second limit
Matching relationship between the part 162 of position, adjustable rotary-cut needle core 141 stretch out the length in outside, so that the negative pressure is inhaled
Draw rotary-cut aspiration needle 100 and be adapted to different lesion environment, expands the application range of the vacuum suction rotary-cut aspiration needle 100.
As shown in figure 3, the first end of needle core fixing piece 142 is provided with the second regulating tank 142a, the part of driving assembly 150
It is arranged in the second regulating tank 142a and the second regulating tank 142a can slides relatively.In this way, utilizing the first set limit
When extension elongation to adjust rotary-cut needle core 141 of part 161 and the second locating part 162, for example, shortening the stretching of rotary-cut needle core 141
Length, at this point, the second locating part 162 and the first locating part 161 move down, meanwhile, needle core fixing piece 142 is also downward simultaneously
It is mobile, at this point, by set the second regulating tank 142a on needle core fixing piece 142, it can be directly along driving assembly 150
Surface slide downward, the position without changing driving assembly 150.
Specifically, as shown in figure 3, driving assembly 150 includes driving battery 151, driving motor 152 and drive link
153, wherein driving battery 151 is electrically connected with driving motor 152, is powered to driving motor 152.The first end of drive link 153
With the output axis connection of driving motor 152, the second end of drive link 153 is arranged in the second regulating tank 142a and can be with respect to the
The sliding of two regulating tanks.Drive link 153 is connect by the second regulating tank 142a with rotary-cut needle core component 140, and drive link 153 is revolved
Turn that rotary-cut needle core component 140 is driven to rotate.
In order to realize the rotation speed of control rotary-cut needle core 141, as shown in figure 3, driving assembly 150 further includes speed regulation button
154, speed regulation button 154 is connect through pedestal 110 to the control terminal of driving motor 152, to adjust turning for driving motor 152
Speed so as to control the revolving speed for the drive link 153 that it is driven, and then can control the rotation that drive link 153 is driven
The rotation speed of needle core 141 is cut, realizes that revolving speed is adjustable.
In order to avoid the hydrops pumped out enters in accommodating chamber 111, as shown in figure 3, vacuum suction rotary-cut aspiration needle 100 is also
Including at least one sealing element 170, which is folded between needle tubing component 120 and rotary-cut needle core component 140.
Specifically, as shown in figure 3, sealing element 170 is between needle core fixing piece 142 and needle tubing fixing piece 122, in this way,
It may insure the environment in sealing between needle core fixing piece 142 and the fixed workpiece 122 of needle tubing, so as to avoid needle tubing 121
Interior hydrops enters in accommodating chamber 111, and then can corrode driving assembly 150 to avoid hydrops, improves vacuum suction rotary-cut and takes out
The service life of suction spindle 100.
It should be noted that the specific structure for sealing element 170 does not define, for example, the sealing element 170 can
In the form of using sealing ring, rubber seal can be preferably used, in such manner, it is possible to which the hydrops pumped out is effectively prevent to enter
In accommodating chamber 111, driving assembly 150 is corroded.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, however the present invention is not limited thereto.For those skilled in the art, essence of the invention is not being departed from
