Abstract
The utility model is related to a kind of CT guided punctures template pin hole coordinate setting sets, including template set main body, line flag galvanized wire, row label galvanized wire, side label galvanized wire etc., each pin hole in real replica can be accurately positioned on CT images.Real-time surgical planning can be made in art rapidly, institute's template pin hole to be used and its position is determined, operation risk can be reduced, operating time can be reduced again by reducing operating difficulty, reduce CT scan number and patient's ray radioactive dose in art.It can achieve the purpose that precisely to treat tumour according to operation plan is adjusted at any time in art.
Description
Technical field
The utility model belongs to area of medical devices, is related to a kind of CT guided punctures template pin hole coordinate setting set.
Background technology
As tumor incidence is higher and higher, various minimally invasive diagnosis, treatment technology are developed rapidly, such as：Percutaneously wear
Pierce biopsy, radioactive prospecting instrument, radio frequency, Microwave Coagulation Therapy etc..But minimal invasive techniques require to puncture precision height, manually puncture skill
Art difficulty is big, and learning cycle is long, manually punctures the consistency it cannot be guaranteed that every doctor, and puncturing template can accurate guided puncture
The trend of needle, so being widely used.
But the pin hole for puncturing template is various, and existing puncture template can not add label at pin hole, can only be in the side of pin hole
The edge of side or template addition label, so the corresponding institute of tumour each needle to be used cannot be told on CT images
Hole, it is often necessary to be repeatedly scanned with verification, not only increase operating time, but also increase the ray of operation risk and patient by according to agent
Amount.
Utility model content
It, can be in view of the above-mentioned problems, the utility model is intended to provide a kind of CT guided punctures template pin hole coordinate setting set
Each pin hole in real replica is accurately positioned on CT images.According to knub position, doctor can be on CT images quickly
It determines institute's pin hole coordinate to be used, real replica institute pin hole to be used is found by template surface label, makes to plan in art
It is fitted with actual template and patient posture, not only can precisely puncture completely, but also operating time can be reduced, reduce operation risk.
After CT scan, patient, which starts operation consent, to take out, and do not contact patient, after disinfection can Reusability, greatly reduce
The surgery cost of patient, social benefit are apparent.
A kind of CT guided punctures template pin hole coordinate setting set includes that template set main body, template cover the side in three faces, is controlled
Different size ducts are reserved up and down, and reserved location and institute template pin hole to be used correspond, and are put into label galvanized wire.
Above-mentioned CT guided punctures template pin hole coordinate setting set length and width and thickness can flexibly be set according to institute's template to be used
It sets, it is rear elastic suitable to be inserted in, and facilitates taking-up.
Further, three face shirt rims of template set setting can be inserted on the upside of the template, extract, can also be covered above template into
With remove.
Further, the label galvanized wire of the internal setting of template set and the interval 1cm of arrangement in column of template pin hole position consistency
Be put into hole, be all put into that hole length and template pin hole covering section length are consistent, can positioning pinholes row coordinate.Under being guided due to CT
The usual 0.5cm of Scan slice thickness is punctured, template pin hole can both mark the needle of interval 1cm at a distance of 0.5cm, row galvanized wire interval 1cm
Hole can find between two arrange and smoothly 0.5 interval pin hole.
Further, the label galvanized wire of the internal setting of template set and the arrangement interval 1cm that embarks on journey of template pin hole position consistency
It is put into hole, often row length differs 1cm, and terminal intersects with row galvanized wire.Can positioning pinholes row coordinate.
Further, the galvanized wire for lateral edges indwelling parallel templates pin hole being covered in template is put into hole.Depth be respectively 2cm and
0.5cm, interval 0.5cm are alternately arranged successively.Due to the CT usual 0.5cm of Conducted Puncture Scan slice thickness, template pin hole is apart
0.5cm, so alternately arranged galvanized wire has clearly showed that the position of scanning, depth are that the galvanized wire of 2cm represents its integer layer,
The galvanized wire that depth is 0.5cm represents corresponding middle layer, the quadrat silk mark difference that integer layer has length different, so can divide
Discern each hand-manipulating of needle hole.On the other hand due to parallel with needle track so the galvanized wire extension artifact generated after CT scan can certain journey
The direction of puncture needle is guided on degree.
Further, center indwelling center peep hole is covered in template, template, template set contraposition can be observed by peep hole
Situation.It can also be inserted into pilot pin by peep hole.
The utility model is intended to provide a kind of CT guided punctures template pin hole coordinate setting set, can be accurately in CT images
Each pin hole in upper positioning real replica.Real-time surgical planning can be made in art rapidly, determines institute's mould to be used
Plate pin hole and its position can reduce operation risk, and operating time can be reduced again by reducing operating difficulty, reduce CT scan in art
Number and patient's ray radioactive dose.It can achieve the purpose that precisely to treat tumour according to operation plan is adjusted at any time in art.By
After CT scan, patient, which starts operation consent, to take out, and do not contact patient, after disinfection can Reusability, greatly reduce disease
The surgery cost of people, social benefit are apparent.
