Under the elastic force effect of spring 5, the lower end of inner core tube 3 is popped up from needle tubing 1 is punctured, at this point, when puncture needle tubing 1 gos deep into again, due to
The semicircle bulb 3b spherical in semicircle of 3 lower end of inner core tube is in contact with the interior tissue of cavity, the spherical surface of semicircle bulb 3b
Contact directly will not generate damage to inside cavity tissue.
The present embodiment further includes suggestion device with for prompting in puncture process the position for puncturing needle tubing 1, i.e.,
When puncturing needle tubing 1 when puncturing human muscle and when entering body cavity, it can accurately be known by suggestion device and puncture needle tubing 1
The accurate location of the sharp portion 1a of lower end.Suggestion device is arranged in handle 2.
Preferably, in the present embodiment, the suggestion device is color tips device 4, and the color tips device 4 can be
Inner core tube 3 retracts and when compressed spring 5 is shown as a kind of color, is shown as another when 3 lower end of inner core tube is popped up by spring 5
Color.
In conjunction with Fig. 3 and Fig. 4, the color tips device 4 includes upper marking plate 4b and lower marking plate 4a.Upper marking plate 4b
In the top of lower marking plate 4a, the lower end of upper marking plate 4b is connected with the upper end of lower marking plate 4a, the color of upper marking plate 4b
Completely different with the color of lower marking plate 4a, in the present embodiment, upper marking plate 4b is blue, and lower marking plate 4a is red.Subscript
Know and offer transfer passage 4c on plate 4b, lower transfer passage 4d is offered on lower marking plate 4a, upper transfer passage 4c is defeated under
Channel 4d is sent to be connected, lower transfer passage 4d is connected with inner core tube 3.
As above-mentioned it is found that the color tips device 4 when in use, is worn target position when by puncturing needle tubing 1
Thorn, when puncture needle tubing 1 enters human muscle, 3 lower end of inner core tube, which is compressed, at this time is retracted in puncture needle tubing 1 simultaneously compressed spring
5, lower marking plate 4a is moved up, and (it is red for descending marking plate 4a in the present embodiment to the color of marking plate 4a under being that operator observes
Color), when puncture needle tubing 1 enters body cavity, the resistance of 3 lower end of inner core tube is released at this time, under the elastic force effect of spring 5,
The lower end of inner core tube 3 is popped up from needle tubing 1 is punctured, and descends marking plate 4a to move down with inner core tube 3 at this time, what operator observed is subscript
Know the color (upper marking plate 4b is blue in the present embodiment) of plate 4b, such operator just would know that puncture needle pipe 1 arrived
Body cavity position.
It can be seen from the above, reflecting puncture by the color change inside handle 2 by setting color tips device 4
Whether needle tubing 1 reaches body cavity.
Embodiment 2
As shown in figure 5, the present embodiment difference from example 1 is that: the suggestion device be sound prompt device
6, sound prompt device 6 is for carrying out auditory tone cues when inner core tube 3 retracts simultaneously compressed spring 5, in 3 lower end of inner core tube by spring
Sound disappears when 5 pop-up.
As shown in figure 5, the sound prompt device 6 includes buzzer 6a and the battery for powering for the buzzer 6a
6b and trigger board 6c.
The upper end of inner core tube 3 is arranged in trigger board 6c, and the connection for being connected with inner core tube 3 is provided on trigger board 6c
Movable contact spring 6e is provided on channel 6d, trigger board 6c, movable contact spring 6e is electrically connected with battery 6b, be provided in handle 2 for institute
The static contact 6f that movable contact spring 6e is matched is stated, static contact 6f is electrically connected with battery 6b, and buzzer 6a is serially connected in static contact 6f and electricity
In power supply line between the 6b of pond.
Wherein, by the way that interface channel 6d is arranged on trigger board 6c, for hydrops derived from inner core tube 3 and pneumatosis to be guided
It is discharged to output channel 2a, and then by 2 upper end of handle.
As above-mentioned it is found that the sound prompt device 6 when in use, is worn target position when by puncturing needle tubing 1
Thorn, when puncture needle tubing 1 enters human muscle, 3 lower end of inner core tube, which is compressed, at this time is retracted in puncture needle tubing 1 simultaneously compressed spring
5, trigger board 6c is moved up, and movable contact spring 6e and static contact 6f are in contact, and the power supply of buzzer 6a is connected at this time, and buzzer 6a sending mentions
Show sound, when puncture needle tubing 1 enters body cavity, the resistance of 3 lower end of inner core tube is released at this time, under the elastic force effect of spring 5,
The lower end of inner core tube 3 is popped up from needle tubing 1 is punctured, and movable contact spring 6e is separated with static contact 6f phase at this time, and the power supply of buzzer 6a is cut
It removes, prompt tone disappears, and such operator just would know that puncture needle pipe 1 arrived body cavity position.
It can be seen from the above, by setting sound prompt device 6, i.e., by sound prompt device 6 whether issue prompt tone come
Reflection puncture needle tubing 1 whether reach body cavity, avoid have arrived at body cavity puncture needle tubing 1 continue puncture and to chamber
Body organ damages.
In the present embodiment, the sound prompt device 6 be electro-acoustic, can also by the way of physical impacts sending sound
Sound prompt.
Embodiment 3
As shown in fig. 6, the present embodiment difference from example 1 is that: the suggestion device be light prompt device

Light disappears when spring 5 pops up.
Light prompt device 7 includes warning light 7a and battery 7b and trigger board 7c for powering for warning light 7a, touching
The upper end of inner core tube 3 is arranged in hair plate 7c, and the interface channel 7d for being connected with inner core tube 3, touching are provided on trigger board 7c
It is provided with movable contact spring 7f on hair plate 7c, movable contact spring 7f is electrically connected with battery 7b, is provided in handle 2 for matching with movable contact spring 7f
The static contact 7e of conjunction, static contact 7e are electrically connected with battery 7b, and warning light 7a is serially connected in the power supply between static contact 7e and battery 7b
On route.
Wherein, by the way that interface channel 7d is arranged on trigger board 7c, for hydrops derived from inner core tube 3 and pneumatosis to be guided
It is discharged to output channel 2a, and then by 2 upper end of handle.
As above-mentioned it is found that the light prompt device 7 when in use, is worn target position when by puncturing needle tubing 1
Thorn, when puncture needle tubing 1 enters human muscle, 3 lower end of inner core tube, which is compressed, at this time is retracted in puncture needle tubing 1 simultaneously compressed spring
5, trigger board 7c is moved up, and movable contact spring 7f and static contact 7e are in contact, and the power supply of warning light 7a is connected at this time, and warning light 7a sending mentions
Show light, when puncture needle tubing 1 enters body cavity, the resistance of 3 lower end of inner core tube is released at this time, is acted in the elastic force of spring 5
Under, the lower end of inner core tube 3 is popped up from needle tubing 1 is punctured, and movable contact spring 7f is separated with static contact 7e phase at this time, the power supply quilt of warning light 7a
Excision, prompts light to disappear, and such operator just would know that puncture needle pipe 1 arrived body cavity position.
It can be seen from the above, whether issuing light prompt by light prompt device 7 by setting light prompt device 7
Come reflect puncture needle tubing 1 whether reach body cavity, avoid have arrived at body cavity puncture needle tubing 1 continue puncture and it is right
Hollow lumen damages.
Embodiment 4
As shown in Figure 7 and Figure 8, the present embodiment difference from example 1 is that: the suggestion device be scale prompt
Device 8, scale suggestion device 8 can be when inner core tube 3 retracts simultaneously compressed spring 5, and works as 3 lower end of inner core tube by 5 bullet of spring
Scale prompt is carried out when out.
Indicator board 8b and trigger board 8c of the scale suggestion device 8 including graduated scale 8a and for being moved with inner core tube 3,
