Description
Technical field
The present invention relates to medical instruments fields, specifically, being related to a kind of Minimally Invasive Surgery path diverter.
Background technique
The puncture needle that Minimally Invasive Surgery path diverter is guided by direction is formed with elastic diagnosis and treatment needle, at present clinically minimally invasive
Operation pathway is all straight line, can not be by straight line access from vitro when having important histoorgan around some lesions
It directly reaches lesion to be cut off and treated, needs to puncture again, or even repeatedly puncture, and puncture or repeatedly puncture again, no
The damage to surrounding tissue organ is only considerably increased, the occurrence probability of complication is improved, but also is substantially increased minimally invasive
The difficulty of operation, or even operative failure is caused, reduce the application range of Minimally Invasive Surgery, some lesions can not be complete with Minimally Invasive Surgery
At significantly reducing minimal invasive operation effect and patients ' life quality.
Minimally Invasive Surgery not only needs to cut off lesion, it is also necessary to carry out multi-point sampling, local application, particle to knurl
Implanted treatment etc..Currently, in order to uniformly be implanted into particle in knurl as far as possible, tradition punctures pin puncture and carries out the plant of radioactivity grain
It is fashionable, puncture path often is selected with the experience of operator, progress is blind to wear, and needle angle, which is held, is not allowed, and error is larger, puncture needle
Road is unevenly distributed, and generally requires multiple puncture, and multiple CT scan operates and lack of standardization, and complication is more, the radiation that patient receives
Dosage is larger.Conventional puncture needle can only discharge particle from needle tip, to realize multidirectional operation, Zhi Nengzeng in seeds implanted
Add puncture time, if there is no vitals to block around tumour, commonly use seeds implanted template, a few row's needles arranged in parallel, and wears
The increase of thorn number will dramatically increase the generation of complication, increase Implantation matastasis probability.But have around tumour bone,
When the vitals such as blood vessel block, it is not available template, it is equal that radioactive particle cannot achieve cloth, cold spot and hot spot easily occurs, controls
Therapeutic effect is not good enough.
Summary of the invention
The technical problem to be solved by the present invention is to overcome drawbacks described above, provide it is a kind of it is easy to use, puncture accurate, treatment effect
Fruit is significant, Small side effects Minimally Invasive Surgery path diverters.
To solve the above problems, the technical scheme adopted by the invention is that:
Minimally Invasive Surgery path diverter, including puncture needle, the elastic diagnosis and treatment needle matched with puncture needle, the puncture needle packet
Needle tubing portion, Aculeata and needle tip are included, needle tubing portion is equipped with scale, it is characterised in that: the needle tip is cecum, the needle tubing
Portion is equipped with the targeting port of lateral openings, the cecum formation guide angle α of the targeting port and needle tubing portion, institute close to one end of needle tip
The needle point for stating elastic diagnosis and treatment needle is pierced by from targeting port.
As an improvement:
0 ° of 180 ° of < α < of range of the guide angle α.
The guide angle α is 120 °.
Especially in seeds implantation tumour, 120 ° of guide angle just becomes particularly important, in knurl
Maximum cross-section is found, a regular hexagon is drawn, because 120 ° of deflecting punctures exactly meet regular hexagon uniform particle distributed mode
Type requirement, i.e., with one diagonal line of regular hexagon for main puncture path, exactly 120 ° of the angle separated to sideline, elastic particle
The puncture path that implant needle is pierced by from 120 ° of guide angle lateral openings puncture needle is also hexagonal angle, regular hexagon each vertex with
Central point is implanted into particle, and the distribution of particle is uniformly that a lamella of such tumour is achieved that uniform planting.Meanwhile with
Lateral 120 ° of openings puncture needle rotate different opening direction and the different distance on main puncture path, knurl can be carried out
Multiple seeds implanted is achieved that multidirectional uniform particle planting in truly knurl, and completes seeds implanted and only need
A main puncture path is punctured, puncture time is significantly reduced, substantially increases the uniformity of radioactive prospecting instrument.
As a further improvement:
The needle tubing portion is set with graduation indication disk, and the graduation indication disk and needle tubing portion relatively rotate.
The scale unit of the graduation indication disk is 10 °.
The Aculeata is equipped with indicateing arm, and the indicateing arm is corresponding with the opening direction of targeting port.
The instruction is designated as being arranged in arrow raised on Aculeata, and arrow is matched with graduation indication disk.
Graduation indication disk can indicate the rotation angle of puncture needle, make the more accurate of seeds implanted.
As further improvement:
Scale in the needle tubing portion is sequentially increased from needle tip to Aculeata.
Scale in needle tubing portion can show the paracentesis depth of puncture needle, preferably to complete materials and grain to knurl
Sub uniformly implantation.
By adopting the above-described technical solution, the needle tip of puncture needle is cecum in the present invention, it is laterally provided with targeting port, and
There can be different guide angles, play to elastic diagnosis and treatment needle extending direction and guiding function, puncturing Aculeata has side opening side
To indicateing arm, when puncture needle rotation, angle and the direction of aperture position rotation are determined, thus puncture needle completes operation pathway
Straight line portion punctures, and when deflecting being needed to turn round, is pierced by into elastic puncture needle by lateral openings by opening angle deflecting, is formed
Reversible puncture technique establishes curve operation path for Minimally Invasive Surgery and creates conditions, and realizes Minimally Invasive Surgery path locus by straight line
Become bending line.
When having important histoorgan around some knurls, can not directly it be reached by straight line access from vitro
When, direction can be changed by diverter on the basis of beeline channel, turn and be bent to up to lesion, establish a bending operation path,
Reduce unnecessary tissue damage.Technique is significant, greatly reduces damage of the puncture path to surrounding tissue organ, subtracts
The generation of few complication, substantially reduces Minimally Invasive Surgery difficulty, increases the application range of Minimally Invasive Surgery, significantly improve minimally invasive hand
Art therapeutic effect and patients ' life quality.
The present invention will be further described with reference to the accompanying drawings and detailed description.
