Abstract
The utility model discloses a seed implanter under a bronchoscope. The seed implanter under the bronchoscope comprises a catheter and a guide wire capable of being inserted in the catheter, wherein the front head portion of the catheter is sharply tapered, and the inner surface of the tail portion of the catheter is provided with a protruding bayonet. According to the seed implanter under the bronchoscope, the head portion of the catheter is sharply tapered, so that the catheter can be immediately inserted on a nidus after the position of the nidus is confirmed in the process of operation under the bronchoscope, a seed attached to the guide wire is pushed and implanted through the catheter, the front portions of the catheter and the guide wire are bendable, so that the seed implanter can be well used for the operation under the fiber bronchoscope, the usage of externals instruments is reduced, and the injury caused by external puncture on a patient is avoided.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates to specifically a kind of training of breathing for the particle implantation device under the bronchoscope.
Background technology
In the prior art, the apparatus that adopts when implanting radion for the patient is the radion implant needle, is percutaneously advanced into inside tumor by the puncture needle tubing during use, then by the puncture needle needle tubing that deeply punctures particle is transported to lesions position.There is following defective in prior art:
Directly outside puncture meeting causes wound to patient to the puncture needle tubing through the thoracic cavity, and need to determine the position by the CT image documentation equipment during puncture, and use equipment is many, and might the puncture position location inaccurate.
Because the puncture minute hand is the straight minute hand of hard, during puncture not malleable implant direction and position.
The utility model content
Technical problem to be solved in the utility model just provides a kind of implantation device of radioactive particle accurately being implanted focus under bronchoscope.
This utility model adopts following technical scheme:
Particle implantation device under a kind of bronchoscope comprises conduit and can insert the interior seal wire of conduit that described conduit fore head is sharp cone distal, and the catheter tail inner surface has the protrusion bayonet socket.
In a preferred embodiment, described conduit material be outer surface with the elastic stainless steel of the close circle fillet of screw, the external diameter of conduit is 1.5mm.
In a preferred embodiment, the anterior material of described seal wire be outer surface with the elastic stainless steel of the close circle fillet of screw, the rear portion is the rigidity stainless steel silk, there is one section protruding endless belt the junction of front and rear.
In a preferred embodiment, described seal wire rear portion rigidity stainless steel silk also can be two stainless steel silks of turning round as twisted shape.
In a preferred embodiment, multistage projection endless belt is set on the rigidity stainless steel silk of described seal wire rear portion.
In a preferred embodiment, described conduit and seal wire front portion are all flexible.
The beneficial effects of the utility model are:
Because conduit and seal wire front portion are the elastic stainless steel of the close circle fillet of screw, therefore both flexible, certain dynamics is arranged again, when under branchofiberoscope, operating, not only can reduce the use of external device, also avoided the patient is carried out the wound that outside puncture causes.
Because catheter head is sharp cone distal, so can prick immediately on focus after determining lesions position when under bronchoscope, operating, improved the accuracy of particle implantation position.
Because the seal wire rear portion is the hard steel wire, the junction, front and rear part is with the endless belt of projection, and the catheter tail inner surface has the protrusion bayonet socket, can more strong accompanying particle is pushed in the focus go when inserting.
Multistage projection endless belt is set on the rigidity stainless steel silk at seal wire rear portion, can be anti-skidding, and can strengthen the motive force of seal wire, better particle is implanted in the focus and gone.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining this utility model, and be not used in restriction this utility model.
Embodiment 1, sees also Fig. 1 and Fig. 2, and the present embodiment discloses a kind of particle implantation device that uses under branchofiberoscope, comprises conduit 1 and can insert the interior seal wire 2 of conduit, and described conduit 1 fore head is sharp cone distal.The material of this conduit 1 be outer surface with the elastic stainless steel of the close circle fillet of screw, the external diameter of conduit 1 is 1.5mm, the catheter tail inner surface has the protrusion bayonet socket, sees also Fig. 5.Described seal wire 2 is comprised of two parts, anterior material be outer surface with the elastic stainless steel 21 of the close circle fillet of screw, the rear portion is rigidity stainless steel silk 22, seal wire anterior 21 is flexible, 22 inflexibility of seal wire rear portion, there is one section protruding endless belt 23 junction at seal wire anterior 21 and seal wire rear portion 22.
Please participate in Fig. 3, this figure has omitted the close circle fillet of screw on conduit and the seal wire, particle implantation device is attached to seal wire 2 heads with radioactive particle when work, in the side passage that at first conduit 1 is inserted on the bronchoscope, determine after the lesions position, conduit 1 is pricked on focus, then the seal wire 2 that is adhering to particle is inserted in the conduit 1, because an endless belt 23 that protrudes is arranged on the seal wire 2, and be rigidity stainless steel silk 22 positions of seal wire behind the endless belt 23, so when endless belt 23 contacts the bayonet socket of pipe inner walls, have and stop, push this moment with strength, and endless belt 23 will pass through bayonet socket, and the strength of this promotion can help the radion of seal wire 1 head to be implanted on patient's focus.
Embodiment 2, and all the other parts are identical with embodiment 1, and difference is that the rigidity stainless steel silk at described seal wire rear portion also can be two stainless steel silks of turning round as twisted shape, and this locates inflexibility.
Embodiment 3, see also Fig. 4, and all the other parts are identical with embodiment 1, and difference is to arrange on the rigidity stainless steel silk at described seal wire 2 rear portions multistage projection endless belt 23.Push seal wire and particle is implanted unsuccessful situation for disposable, can realize repeatedly pushing by the external force side particle is implanted in the focus.
