Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly the reflective ball cover of one and witch ball.
Background technology
In surgical navigational or motion capture system, need to follow the tracks of the position of operating theater instruments or Moving Objects.Existing navigator or motion capture device adopt the bead being pasted with reflective coating, but when directly reflective coating being pasted onto on bead, reflective membrane has larger flexibility, is difficult to directly be processed into spherical and keep spherical, makes its taping process not easy to operate.And this technique is very high to bead surface required precision, make its processing cost higher.
Utility model content
The purpose of this utility model is to solve above-mentioned Problems existing, provides a kind of reflective ball cover and witch ball.
The technical solution of the utility model is as follows:
A kind of reflective ball cover, for being arranged on plastic carrier outside, described reflective ball cover is made up of plural split, and described each split comprises PVC film and reflective membrane, and described reflective membrane covers in described PVC film.
In a preferred embodiment, described reflective ball cover is made up of two splits.Certainly, described reflective ball cover also can be made up of the split of 3 or more, does not do exhaustive herein.
Preferably, described each split is hemispherical.
In one embodiment, described reflective ball cover is pasted onto on described plastic carrier, and described plastic carrier and described reflective ball cover have contact surface.Plastic carrier can select the various shape with reflective ball cover with contact surface, is for example and without limitation to spherical, square, taper etc.
In a preferred embodiment, described plastic carrier is spheroid.
This utility model is a kind of witch ball simultaneously, it comprises plastic carrier from inside to outside successively, is arranged on the reflective ball cover of described plastic carrier outside, described reflective ball cover is made up of plural split, and described each split comprises PVC film and reflective membrane, and described reflective membrane covers in described PVC film.
In a preferred embodiment, described reflective ball cover is made up of two splits.Certainly, described reflective ball cover also can be made up of the split of 3 or more, does not do exhaustive herein.
Preferably, described each split is hemispherical.
In one embodiment, described reflective ball cover is pasted onto on described plastic carrier, and described plastic carrier and described reflective ball cover have contact surface.Plastic carrier can select the various shape with reflective ball cover with contact surface, is for example and without limitation to spherical, square, taper etc.
In a preferred embodiment, described plastic carrier is spheroid.
Compared with prior art, the beneficial effects of the utility model are as follows:
The first, this utility model covers reflective membrane in PVC film, the moulded manufacturability that PVC film is good can be utilized, be processed into high-precision hemispherical, ensure that on ball cover, reflective membrane is uniformly distributed simultaneously, thus improve stability and the accuracy of the reflected infrared ray of reflective ball cover;
The second, witch ball cover of the present utility model covers on plastic carrier, thus utilizes the reflective membrane of reflective ball cover to substitute bead surface of the prior art to carry out reflected infrared ray, thus reduces plastic carrier surface finish requirements, makes manufacturing cost lower.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view comprising the witch ball of reflective ball cover of this utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.Following examples only for illustrating, and are not used in restriction protection domain of the present utility model.
Embodiment
Refer to Fig. 1, a kind of witch ball of the present embodiment, it comprises plastic sphere carrier 1 from inside to outside successively, is arranged on the reflective ball cover of plastic sphere carrier 1 outside, this reflective ball cover is made up of two splits, described each split comprises PVC film and reflective membrane respectively, and described reflective membrane covers in described PVC film.Wherein the first split of reflective ball cover is provided with PVC film 11, reflective membrane 12, second split of reflective ball cover is provided with PVC film 21, reflective membrane 22, wherein reflective membrane 12,22 overlays respectively in PVC film 11,21, and PVC film 11,21 arranges the outer surface of plastic sphere carrier 1 respectively.Wherein, PVC film shown in Fig. 1 and reflective membrane are only schematic diagram, its thickness and relative to the ratio of plastic sphere carrier and the ratio of PVC film and reflective membrane thickness not as actual product dimension reference, be also not used in the thickness limiting PVC film and reflective membrane in this utility model.The shape of plastic carrier also can select the shape that can contact with reflective ball cover except spherical, does not limit herein.
This reflective ball cover is first processed into hemispherical, attaches on plastic sphere carrier 1 afterwards respectively.
Because reflective membrane has good flexibility, be therefore difficult to directly be processed into spherical and keep spherical.And PVC film has good moulded manufacturability, any shape can be processed into very easily; After PVC film surface coverage reflective membrane, the moulded manufacturability that PVC film is good can be utilized, be processed into high-precision hemispherical, ensure that on ball cover, reflective membrane is uniformly distributed simultaneously, thus improve stability and the accuracy of the reflected infrared ray of reflective ball cover.Such technique also reduces the requirement of the outer surface precision to plastic sphere carrier itself, be more prone to and save cost, thus this utility model also reduces manufacturing cost owing to making high-precision film than the high-precision spherome surface of making.
Meanwhile, the medical reflective ball cover in the present embodiment adopts split-type structural, thus allows the plastic carrier using different internal structure and appearance, thus has expanded its scope of application.
Medical reflective ball cover of the present utility model take plastic sphere as carrier, any angle of Space Rotating all can reflecting device launch infrared ray, then by receiving equipment receive infrared light spot as identification point.
This utility model preferred embodiment is only above.Preferred embodiment does not have all details of detailed descriptionthe, does not limit the detailed description of the invention that this utility model is only described yet.Obviously, according to the content of this description, can make many modifications and variations.This description is chosen and is specifically described these embodiments, is to explain principle of the present utility model and practical application better, thus makes one of ordinary skill in the art can utilize this utility model well.This utility model is only subject to the restriction of claims and four corner and equivalent.
