To refer to above description.
The localization method includes:
In conjunction with Fig. 5, the piercing needle 111 of pilot pin 10 is pierced into 100 in target, the position of piercing needle 111 is adjusted, makes
Piercing needle 111 is pierced into destination organization 300, so that positioning region and destination organization 300 are relatively fixed；
In conjunction with Fig. 6, sheath 20 is penetrated along one end that pilot pin 10 is located at outside target 200, and along pilot pin 10 by sheath
Pipe 20 is inserted into 100 in target；
In conjunction with Fig. 7, pilot pin 10 is pulled, moves the piercing needle 111 of pilot pin 10 into sheath 20；
In conjunction with Fig. 8, the syringe needle of sheath 20 is pierced into destination organization 300, and pilot pin 10 is detached into sheath 20；
In conjunction with Fig. 9, ablation needle 40 is inserted into sheath 20, and along sheath 20, the syringe needle of ablation needle 40 is pierced into target
In tissue 300.
Steps are as follows for specific clinical use when carrying out puncture operation:
In conjunction with Fig. 5, under the guidance of the medical images such as ultrasound, CT, holds handle 14 and (suffer from piercing needle 111 around target
Person) normal tissue 400 puncture into 100 in target；The position for adjusting piercing needle 111 makes piercing needle 111 precisely be pierced into mesh
The center position of tissue 300 is marked, annular groove 112 can be embedded in destination organization 300 to live its " lock ", at this point, the first needle at this time
The part of body 11, the second needle body 12 and third needle body 13 is respectively positioned on 100 in target, and the remainder of third needle body 13 is located at mesh
Mark outer 200；
In conjunction with Fig. 6, handle 14 is removed, keeps the first needle body 11, the position of the second needle body 12 constant；Then, along third
Sheath 20 is inserted by the right end of needle body 13 along third needle body 13, after the right end of third needle body 13 is pierced by sheath 20, with one
Hand pinches and pulls the right end of third needle body 13, and another hand pinches the connector 30 in sheath 20 and takes advantage of a situation in interior insertion target
100, the relative movement distance of the two can be grasped in real time by the scale 131 on third needle body 13 at this time；
In conjunction with Fig. 6 and Fig. 7, during pulling the right end of third needle body 13 and interpolation sheath 20 of taking advantage of a situation, the second needle body 12
Straight-bar state (such as Fig. 7) can be slowly become by bending state (such as Fig. 6) under the constraint effect of sheath 20, in the process, the
Two needle bodies 12 generate deformation, the first needle body 11 meeting diametrically moving along sheath 20, until coaxial with sheath 20；
It extracts pilot pin 10 out sheath 20 by force by the syringe needle insertion destination organization 300 of sheath 20 in conjunction with Fig. 8, positions
After needle 10 is detached from sheath 20, the second needle body 12 can restore bending state；
In conjunction with Fig. 9, ablation needle 40 (microwave melt needle, radio frequency ablation needle, laser ablation needle) is inserted into sheath 20, until ablation
The syringe needle of needle 40 hits exactly under the guidance of sheath 20 and is inserted to destination organization 300, then can disappear to 300 real-time and precise of destination organization
Melt.
Specifically, in conjunction with Fig. 5 and Fig. 6, the destination organization 300 is blocked by normal tissue 400, in curved second needle body 12
Under effect, normal tissue 400 can be bypassed, piercing needle 111 is directly pierced into destination organization 300.In conjunction with Fig. 7,
Fig. 8 and Fig. 9, by the drawing of pilot pin 10, destination organization 300 is moved to the position that do not blocked by normal tissue 400, so that disappearing
The syringe needle for melting needle 40 can be accurately pierced into destination organization 300.
It should be noted that above-mentioned target can be understood as patient, 100 be can be understood as in human body in target,
Target outer 200 can be understood as outside human body, and destination organization 300 can be understood as tumour, and normal tissue 400 can be understood as
It is bone, blood vessel or nerve.It of courses, which is also possible to animal, and destination organization 300 is also possible to other lesions.
In addition to above-mentioned function, which can also realize the function of puncture biopsy needle, in use, first by pilot pin 10
It is punctured into 100 in target around the normal tissue 400 of target, and by adjusting position, is accurately pierced into destination organization 300, this
When, the insertion of partial target tissue 300 is had in annular groove 112, pinches the right end of pilot pin 10, while sheath 20 is inserted into, directly
To annular groove 112 is wrapped, the cladding of destination organization 300 for making insertion wherein, then pulls out sheath 20 and pilot pin 10 together
Out, it may be implemented to carry out puncture sampling to the destination organization 300 for being difficult to puncture sampling.
Meanwhile sheath 20 can be also used for the suction of 300 inside cyst fluid of destination organization, local anaesthesia, physiological saline
Deng then carrying out local ablation therapy again, tumour inactivating efficacy can be increased, prevent from infecting and be recurred after controlling.
The positioning device has at least the following advantages:
1, the second needle body 12 of the pilot pin 10 is in bending, and puncture track is camber line, can be kept away when puncturing in this way
The normal tissue 400 for opening front, is precisely punctured；
2, integrative medicine image (ultrasound, CT etc.) uses, can be using different angles and the second needle body 12 of arc length, in this way
Adjustment number when puncture can be reduced, the damage of normal tissue 400 is mitigated.
3, it is applicable to the multiple types heat such as microwave melt needle, radio frequency ablation needle, laser ablation needle, cryoablation needle and disappears
The auxiliary positioning for melting needle and puncture biopsy needle punctures, and applicable surface is very wide；
4, components are hardly damaged, clinical adaptable；
5, structure is simple, easy to operate, and the device simple production process, cost are extremely low and reusable, can subtract significantly
Light patient's medical expense.
In conclusion the pilot pin 10 can be improved the precision of Needle localization the present invention provides a kind of pilot pin 10,
Enable 20 precise positioning of sheath engaged therewith, finally realizes the precise positioning of ablation needle 40, entire position fixing process is to just
Often the damage of tissue 400 is smaller.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
