Description
Technical field
The present invention relates to the puncture localization needle used in a kind of medical apparatus and instruments, especially a kind of lung tumors piercing process,
Specifically one kind can prevent lung tumors position movement with respiratory movement, in order to carrying out tumor aspiration biopsy or doing swollen
Tumor ablation and the tumor puncture positioning needle of placement radion treatment.
Background technology
The basis of oncotherapy is definitive pathological diagnosis, and definitive pathological diagnosis often rely on tumor puncture and take biopsy.Wear to reduce
The damage of thorn normal tissue, accurately tumor puncture is extremely important.Meanwhile, the ablation of tumor, radion implantation are controlled
The enforcement of the treatment meanss such as treatment, it is also desirable to the accurate puncture to tumor.But in actual piercing process, particularly with lung, vertical diaphragm
In the tumor at position, due to being affected by patient respiration, its knub position can be with the fluctuating of breathing in certain scope
It is mobile, and this movement inherently directly affects the precise positioning of tumor puncture, for this purpose, doctor must be observed when operating repeatedly,
Adjustment inserting needle position and angle, while needing patient to carry out breathing cooperation.Nonetheless, also Jing is often punctured to normal structure, makes
Into the infringement of patient.Particularly with less lung tumors, below 6 millimeters, doctor cannot almost be worn such as diameter
Thorn.In this regard, there is no good solution at present.
The content of the invention
The purpose of the present invention is to cause to puncture difficulty because knub position is indefinite in aspiration biopsy for breast tumor
Problem, designs a kind of easy tumor puncture positioning needle that tumor can be made almost to remain stationary as.
The technical scheme is that：
A kind of tumor puncture positioning needle, is characterized in that it includes sheath 1 and grasping pin 2, and the tip of sheath 1 is in acicular texture, separately
One end is provided with operation handle 5, and grasping pin 2 is sleeved in sheath 1, and the front end for grasping pin 2 is connected with the bullet in umbrella frame shape after expansion
Property claw hook 3, the elastic claw hook 3 can be accommodated in sheath 1, and the other end for grasping pin 2 is provided with operating side 4, and the tail end for grasping pin 2 has
Little sheath 6, can will be 3 harvest of elastic claw hook a branch of, be easy to pass in and out sheath 1 tail end；The outer wall of sheath 1 is equipped with little rubber closure 7, can
Move up and down in the outer wall of sheath 1, its role is to control the depth that sheath 1 is pierced into body.
The quantity of described elastic claw hook 3 is at least three, and they are distributed on the end of grasping pin 2.
Described elastic claw hook 3 and grasping pin 2 can be extracted out from sheath 1, are carried out biopsy, ablation in order to Jing sheaths and are controlled
Treat.
Described little sheath 6 be arranged on sheath 1 tail end, elastic claw hook 3 exit and into sheath 1 tail end when, it is little
Sheath 6 will be 3 harvest of elastic claw hook a branch of, is easy to pass in and out the tail end of sheath 1；6 head end of little sheath is less than the internal diameter of sheath 1, tail
Hold bigger than the internal diameter of sheath 1, be easy to for elastic claw hook 3 to send into sheath 1, but little sheath 6 oneself will not be packed into sheath 1.
Beneficial effects of the present invention：
Present configuration is simple, and tumor can be caught by anterior umbrella frame shape elasticity claw hook, prevent which from moving, be conducive to being punctured
Biopsy and ablation, the operation for placing radion etc..
Present configuration is simple, easy to use, can greatly improve the speed and precision of tumor puncture, while to greatest extent
Reduce the damage to tumor normal surrounding tissue.
The present invention can a pin it is multiplex, grasping positioning terminate after also can be taken off grasp pin, carry out from sheath biopsy, ablation
Treatment, or directly grasping pin is taken out from sheath as common puncture needle and used.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is use state structural representation of the present invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-2.
A kind of tumor puncture positioning needle, it includes sheath 1 and grasping pin 2, and in acicular texture, tail end sets at the tip of sheath 1
There is operation handle 5, grasping pin 2 is sleeved in sheath 1, the front end for grasping pin 2 is connected with the elastic claw hook in umbrella frame shape after expansion
3, the quantity of elastic claw hook is 3-6, and they are distributed on the head end of grasping pin 2, is in arc-shaped after each expansion of elastic claw hook 3,
Outer end is tip, in order to pierce and tumor in, realize positioning, the elastic claw hook 3 can be accommodated in sheath 1, grasp the another of pin 2
End is provided with operating side 4.The little sheath 6 entered for grasping pin 2 is installed in the tail end of sheath 1, sheath 1 is exited in elastic claw hook 3
When, little sheath 6 will be 3 harvest of elastic claw hook a branch of, is easy to pass in and out the tail end of sheath 1.Internal diameter of 6 head end of little sheath than sheath 1
Little, tail end is bigger than the internal diameter of sheath 1, is easy to for elastic claw hook 3 to send into sheath 1, and little sheath 6 oneself will not be packed into sheath 1.
The outer wall of sheath 1 is equipped with little rubber closure 7, can move up and down in the outer wall of sheath 1, can control the depth that sheath 1 is pierced into body.
Puncturing with routine when the present invention is used, the general direction of tumor is stabbed from skin with the tip of sheath 1 first.Thorn
Enter to after tumor or tumor vicinity, promote forward the operating side 4 of grasping pin 2, the head end of grasping pin 2 is exposed from sheath, this
When, elastic claw hook 3 launches in the presence of elastic force and is pierced in the tissue of tumor or tumor vicinity, firmly catches tumor,
Again rubber closure 7 is pushed into and is in close contact with skin, now positioning needle is fixed and cannot be moved, and its tumor for being caught on also just cannot
It is mobile.Now, you can aspiration biopsy, ablation are relievedly carried out to tumor, the treatment such as radioactive particle is placed.Treat above-mentioned behaviour
After work terminates, only operating side 4 need to be pulled back, you can elastic claw hook 3 is taken in sheath, then taken out together with sheath, it is complete
Into whole operation process.If biopsy or treatment need to be carried out to the position that the positioning needle is located, only need to be by grasping pin 2 together with elastic claw
Hook 3 is exited from sheath 1 together（When the caudal end egress of sheath 1 is retreated to, need to will be 3 harvest of elastic claw hook a branch of with little sheath 6,
To prevent elastic claw hook 3 from exiting after sheath 1 because the blood on hook or tissue are dished out by elastic reaction）, then by biopsy needle or disappear
Melt pin Jing sheaths 1 and be pierced into desired position.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
