Specific embodiment
More detailed description is done to the embodiments of the present invention below in conjunction with attached drawing and appended drawing reference, makes to be familiar with ability
The technology people in domain can implement accordingly after studying this specification carefully.
Embodiment: in conjunction with Fig. 1, a kind of puncture needle component for lung's radiation treatment.
Including puncture needle 1, the puncture needle 1 includes needle point 11 and needle dry 12, and the needle dry 12 is hollow circular-tube structure, needle
Dry 12 hollow circular-tube structure is to provide the channel into human body for implantation radiation particle for radioactive particle.Needle point 11
Setting does 12 tops in needle, and needle does 12 outer walls and indicates graduation mark 13.Graduation mark 13 described in the present embodiment from apart from needle point 1~
1.5 centimeters are initially as start index " 0 ", and to backshank successively in place's reference mark per cm, per cm is divided into milli again
Rice reference mark, the setting of graduation mark 13 can 1 paracentesis depth of venipuncture needle, to guarantee the accurate of radioactive prospecting instrument
Property and safety.
Positioning cap 3,3 sets of the positioning cap are done the 12 outer and dry 12 interference fit connections of needle in needle, and positioning cap 3 is enable to position
12 any position is done in needle.Positioning cap 3 is used cooperatively with the graduation mark 13 on needle dry 12, according to the predetermined puncture needle of operation plan
After 1 paracentesis depth, positioning cap 3 is allocated to the graduation position of corresponding graduation mark 13, can be known whether by positioning cap 3
It is pierced into designated depth.
Needle dry 12 is equipped with the warning lines 14 that a loop is recessed by 4~7 millimeters of caudad places, warning line 14 show be herein
Maximum paracentesis depth, due to moment variations, if continuing deeper into the stabilization that will be unable to smoothly extract or be unable to control puncture needle 1
Degree, being easy, which glances off puncture needle 1 in vivo, causes danger.
The bottom of positioning cap 3 described in the present embodiment is equipped with a circle boss 32, can pass through boss when puncture needle 1 is pierced into
32 whether coating surface judge whether puncture needle 1 has reached designated depth.
Preferably, 3 material of positioning cap is transparent rubber, since in needle to do 12 outer with dry 12 interference of needle for 3 sets of positioning cap
It being cooperatively connected, transparent rubber has certain elasticity, positioning cap 3 can on the one hand done in needle and moves and positions on 12 and will not be broken,
On the other hand graduation mark 13 can also be obviously observed.
Guard bar 2, the guard bar 2 include loop bar 21 and spacing head 22, do for 21 sets of loop bar in needle and do 12 cunnings in 12 with needle
With connection, spacing head 22 is arranged in 21 tail portion of loop bar.
Spacing head 22 described in the present embodiment is cylinder, and the diameter of spacing head 22 is greater than the outer diameter of needle dry 12, spacing head
22 effect is first is that will not fully enter needle dry 12 to limit loop bar 21, when in use can be with hand second is that in order to hold conveniently
Hold the extraction of spacing head 22, insertion guard bar 2.Guard bar 2 is covered in puncture needle 1, is put in implantation when puncture needle 1 is pierced into lung
Extract guard bar 2 when penetrating property particle out.Doing 12 due to the needle of puncture needle 1 is hollow circular-tube structure, is being pierced into lung by natural compression
There is the risk of twist distortion when portion, 2 sets of guard bar in puncture needle 1, can guarantee the intensity of puncture needle 1, guarantee that puncture needle 1 exists
Deformation will not be caused when being pierced into lung due to stress, security risk is reduced, guarantees precision.On the other hand, the setting energy of guard bar 2
Enough guaranteeing that needle dry 12 is internal when in use will not fall into impurity and dust, improves wholesomeness, mentions for implantation radiation particle
For good channel environment.
It preferably, is fillet at the top of loop bar 21 described in the present embodiment in order to improve safety, to guarantee that loop bar 21 pushes up
Portion will not scratch needle when being inserted into needle and doing 12 inside and do 12 inner walls, guarantee that the channel of implantation radiation particle is not destroyed.Loop bar
21 top fillet design also protect operator using when preserve from, guarantee safety.
In order to guarantee puncture strength, the needle point 11 in conjunction with described in attached drawing 1 is 1~3 bevel structure, and preferably monocline face is tied
Structure, pinpoint inclined plane angle are best when being 15 °~20 °.
11 structure of needle point in conjunction with described in attached drawing 2 is conical structure, and taper is 1:2~1:4.
The present embodiment is exemplarily described above in conjunction with attached drawing, the utility model implements not by above-mentioned side
The limitation of formula, if the improvement of the method concept of the utility model and the various unsubstantialities of technical solution progress is used, or
It is not improved that the conception and technical scheme of the utility model are directly applied into other occasions, in the protection of the utility model
Within the scope of.
