Description
Technical field
The utility model relates to the medical instruments of puncturing operation, draw more particularly, to a kind of Percutaneous lung puncture three-dimensional laser
Lead device.
Background technique
CT positions lower percutaneous pneumoncentesis (hereinafter referred to as lung is worn) and is widely used in clinical multiple subjects.Including percutaneous lung
The preoperative Needle localization of percutaneous biopsy, small pulmonary artery, lung neoplasm interventional therapy (ablation, seeds implanted) etc..It is thoracic surgery, breathing
Internal medicine and most frequent one of the operation of Internal Medicine-Oncology are the important methods for obtaining Lung neoplasm Pathologic specimen and clarifying a diagnosis, especially
To the case of bronchoscopic biopsies and the premise of lung neoplasm interventional therapy cannot be passed through.In recent years, with high-resolution spiral
CT's is universal, and the recall rate of Small pulmonary nodule is higher and higher.To can be suspected of the Small pulmonary nodule of the early stage of lung cancer, under row CT guidance
Drug eluting stent art is the important method of clear pathological diagnosis.Some clinical patient is examined according to CT images performance
Break as the early stage of lung cancer and undergos surgery.In the patient to undergo surgery in this section, the Lung neoplasm for having 10-30% operation to cut is through disease
Reason, which checks, to be confirmed not to be lung cancer.If operation consent can do the aspiration biopsy of Lung neoplasm, first clear pathological diagnosis re-treatm ent, this 10-
30% patient can be to avoid unnecessary operation wound.But clinically Lung neoplasm (such as diameter 1cm or less lesser to diameter
Tubercle) carry out percutaneous transthoracic needle biopsy be very difficult.It is not only difficult to lesser small pulmonary artery aspiration biopsy, it is same right
In the puncture ablation for the malign lung nodules patient for not being resistant to operation, and the seeds implanted of the small metastatic tumor of lung in early detection
All exist in equal operating process because Lung neoplasm is smaller, puncture needle cannot be accurately through Lung neoplasm and the case where influence diagnosis and treatment.
Difficult lung is worn, needed in operating process repeatedly CT scan determine puncture needle position and repeatedly withdraw of the needle inserting needle,
Adjust puncture angle.On the one hand repeatedly CT scan increases patient by the dosage radiated, and on the other hand withdraw of the needle inserting needle increases repeatedly
Add the wound of patient.Therefore, clinically there is urgent demand to accurately Percutaneous lung puncture technology at present.
The guiding device clinically used at present improves the accuracy that lung is worn to a certain extent, but for lesser lung knot
It is relatively dissatisfied to save effect, one of the main reasons is that these guiding devices need operator to maintain a position by hand to wear to guide
Thorn, is easy to appear displacement, the channeling direction of guiding device is made small deviation occur.Utility model device is fixed on CT bed, is led to
The accurate puncture of Lung neoplasm is realized in the three-dimensional guidance for crossing laser beam.Overcome the deviation that fixed guiding device occurs by hand.
Summary of the invention
The purpose of the utility model is to provide one kind to be accurately positioned, and realizes the Percutaneous lung puncture three-dimensional laser precisely punctured
Guide device.
To achieve the above objectives, the present invention adopts the following technical solutions:
Percutaneous lung puncture three-dimensional laser guide device is equipped with mounting, sliding block, guide support and Laser Goniometer；
Mounting is equipped with arch slideway, and sliding block and arch slideway packaged type cooperate, and sliding block and arch slideway pass through fastener
Locking, guide support are fixedly connected with a slide block by fastener, and Laser Goniometer is fixed on guide support top, Laser Goniometer
Laser beam guide hole direction set by the beam direction face guide support lower part emitted.
Further,
The mounting is arch mounting, and the arch slideway is the arcuate apertures on arch mounting center line.
The guide support is rod-shaped guide support, and the lower part of rod-shaped guide support is equipped with hollow laser beam guide hole.
The fastener is fastening screw.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Sliding block can be moved along the arch slideway of mounting, and be fixed on any position of mounting.Laser Goniometer and guidance branch
Frame is fixed on sliding block, and Laser Goniometer is rotatable, is converted angle (angle between level), and project accordingly in front end
The cross laser of angle, i.e. angle between the light and ground of cross laser focus are equal to the angle shown on inclinometer.Make
Used time: the utility model is placed on CT lathe.It marks, and cooks up path, the angle, depth of puncture on CT image
Degree.The position of sliding block and the angle of Laser Goniometer are adjusted, the angle on Laser Goniometer is made to plan the angle of inserting needle, angle
The cross laser focus projected on instrument is on entry point, and the light of cross laser focus is the route of puncture needle inserting needle at this time.
When inserting needle, entry point inserting needle of the puncture needle from label is held, adjusts backshank direction, laser beam guiding puncture direction makes inserting needle mistake
The focus of cross laser is hit exactly in backshank always in journey, after inserting needle to predetermined depth, stops inserting needle, check CT understands puncture needle position
It sets.
It can be seen that the utility model can be accurately positioned, realizes and precisely puncture.And structure very simple, it is easy to operate.
Through practice examining, excellent.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram.
Specific embodiment
Referring to Fig. 1, Percutaneous lung puncture three-dimensional laser guide device is equipped with mounting 1, sliding block 3, guide support 7 and laser angular
Spend instrument 6.
Mounting 1 is equipped with arch slideway, and sliding block 3 and arch slideway packaged type cooperate.Sliding block 3 and arch slideway pass through fastening
Part 2 (being equipped with several) locking, guide support 7 are fixedly connected by fastener 4 with sliding block 3.Laser Goniometer 6 passes through connector
5 and 7 top of guide support, the direction face guide support for the laser beam 8 that Laser Goniometer 6 is emitted are fixed on through fastening screw
The guide hole direction of laser beam 8 set by 7 lower parts, Laser Goniometer 6 are equipped with display screen.
The mounting 1 is arch mounting, and the arch slideway is the arcuate apertures on 1 center line of arch mounting.It is described to draw
Leading bracket 7 is rod-shaped guide support, and the lower part of rod-shaped guide support 7 is equipped with hollow laser beam guide hole.The fastener 2 and 4
For fastening screw.
Application examples is given below.
Sharing 97 patients tries out the guide device at present.As the result is shown: Lung neoplasm >=1cm, (inserting needle is deep for paracentesis depth
Degree) < 10cm case, one-time puncture up to predetermined position rate be 95.5%；Lung neoplasm >=1cm, paracentesis depth >=10cm disease
Example, it is 83.6% that one-time puncture, which reaches predetermined position rate,；Lung neoplasm < 1cm case, one-time puncture are up to predetermined position rate
40.5%.It is analyzed for being unable to one-time puncture up to the case in predetermined position.Lung neoplasm < 1cm case, the master of puncture failure
It wants the reason is that the relative position of Lung neoplasm and wall of the chest point of puncture changes patient's flesh when leading to puncture failure, i.e. inserting needle when inserting needle
Meat is shunk, the increase of thorax Breathing movement causes the relative position between small pulmonary artery and the wall of the chest to change.Clinical application result
No matter display: from which angle being punctured in which point inserting needle of the wall of the chest using the guide device of above-mentioned bow-shaped support structure, can
It is accurately guided with laser beam, improves the accuracy that lung is worn, reduce complication.
