In embodiment of above, first said the step being welded to metal welding assembly on instrument, after describe and will install
The step of shell and tag combination, but the mounting means of the present invention is not limited thereto, and will first install shell and tag combination,
Metal welding assembly is welded on instrument again equally can be with.
Fig. 4 is the schematic diagram after installation is complete, and mounting assembly is stably mounted in surgical instrument 80, RF tag 70
Shell 50 is mounted to be wrapped up.The embodiment of the present invention one also provides the instrument for being equipped with radio frequency mounting assembly as described above.This
The mounting assembly and instrument that inventive embodiments one provide, it is small, reading performance is good because of built-in RF tag, it is very suitable for
To carry out the tracking and managing of instrument on instrument.Also, mounting assembly provided by the invention is simple in structure, and installation method is steady
It is qualitative good, it is also very applicable for instrument.
In the attached drawing of embodiment one, the shape of the mounting portion 61 of metal welding assembly 60 is strip, in other implementations
In mode, mounting portion 61 can also be other shapes, such as column.
Embodiment one is illustrated so that RF tag mounting assembly is mounted in surgical instrument as an example, still, in the present invention
It states the instrument in embodiment and is not limited to surgical instrument, for example can also be implantation material, the substitute of implantation material, prosthese, tool,
And with industry, computer, railway, automobile, ship, aviation etc. are relevant wishes to be flagged for ensuring its identification and traceable
Any object.
Simultaneously, it should be noted that in the embodiment of the present invention one, the monnolithic case shape of RF tag mounting assembly
For cuboid, but the present invention does not limit the shape of RF tag mounting assembly, can be cuboid, can also be pros
Body, cylinder or irregular stereochemical structure.In other words, installation shell and the shape of metal welding unit can be arbitrary shapes
Shape, as long as ensureing that the two can be fastened mutually.
The RF tag mounting assembly that the embodiment of the present invention one provides further includes a RF tag, referring to FIG. 5, to implement
The schematic diagram for the RF tag 70 that example one provides.RF tag 70 includes dielectric base 71, which can be ceramic base
Bottom is set to 71 positive driving chip 72 of dielectric base and match circuit 73.
RF tag read away from quality be is determined by three big principal elements, first, the sensitivity of driving chip is just；The
Two, the gain size of antenna；The matching degree of third, antenna and driving chip.And it is directed to same antenna form, the increasing of antenna
The size of benefit is associated with the fissipation factor of the size of antenna, thickness, antenna material.The fissipation factor of antenna material is got over
Greatly, antenna gain is smaller, and vice versa.For the Miniature RF label of high-k, because dielectric constant is higher, and Gao Jie
The production technology of electric constant is still immature, and causes the RF tag frequency fluctuation of high-k larger, and stability is inadequate.Its
Secondary, for same material, the fissipation factor of dielectric base is reduced as dielectric constant increases, therefore dielectric base
Dielectric constant is higher, and the gain for the antenna that can be realized is smaller, therefore reads away from closer.Radio frequency mark provided in an embodiment of the present invention
Label, are arranged match circuit on a dielectric base, can reduce the dielectric constant of dielectric base, therefore the embodiment of the present invention one provides
The dielectric base of low-k, due to low-k dielectric base than high dielectric constant dielectric base loss because
Son is small, so that the antenna ratio high-k antenna gain of comparable size low-k is big, finally so that comparable size
Low-k antenna is read away from more than high-k.Practical comparison, reads away from performance boost 30%-40%.
Referring to FIG. 1, the corresponding driving chip 72 and match circuit 73, install the bottom of the first holding tank 51 of shell 50
It is additionally provided with a third holding tank 53.The floor space of the third holding tank 53 is less than the floor space of the first holding tank 51, and third is held
Slot 53 of receiving is used to accommodate the driving chip 72 and match circuit 73 of RF tag 70.When installing the RF tag component, will penetrate
It, will by just being placed facing towards 51 side of third holding tank for RF tag 70 when frequency marking label 70 are positioned in the first holding tank 51
Driving chip 72 and match circuit 73 are placed in the third holding tank 53.
In embodiment one provided by the invention, RF tag includes match circuit, can improve entire radio frequency installation group
The reading performance of part, meanwhile, radio frequency mounting assembly includes accommodating the third holding tank of match circuit and driving chip, RF tag
And match circuit will not damage, and ensure installation accuracy and reliability.
Embodiment two
RF tag mounting assembly provided by Embodiment 2 of the present invention includes a RF tag, please refers to Fig. 6 and Fig. 7, Fig. 6
For the schematic diagram for the RF tag that two embodiments of the present invention provide, Fig. 7 is the schematic diagram in each main face of RF tag shown in Fig. 6.
RF tag 10 includes dielectric base 11, and dielectric base 11 includes being set to the installation card slot 121,122 of its two opposite side surfaces,
Installation card slot 121,122 is semi-cylindrical, for the matching of follow-up and other mounting assemblies to be installed to surgical instrument；It is set to
11 positive driving chip 13 of dielectric base, match circuit 14, first antenna face 15 and the second antenna surface 16, driving chip 13 divide
Other and first antenna face 15 and the second antenna surface 16 are electrically connected, and match circuit 14 is electrically connected to driving chip 13；It is set to
The third antenna face 17 at 11 back side of dielectric base；It is set to the first connecting line 18 and the second connecting line of 11 side of dielectric base
19, the first connecting line 18 connects first antenna face 15 and third antenna face 17, and the second connecting line 19 connects 16 He of the second antenna surface
Third antenna face 17.
Due to install card slot 121,122 presence, RF tag 10 be unconventional shape profiled shape, but compared to for
The RF tag of the rectangular shape of installation card slot 121,122 is not set, and the electrical length of antenna surface does not change, that is to say, that penetrates
The reading performance of frequency marking label does not change.The electrical length of antenna surface refers to the length from one end of antenna to the other end.Because penetrating
Antenna surface is not arranged in two sides of the setting installation card slot 121,122 of frequency marking label 10, and it is in place to install 121,122 institute of card slot
The partial volume for only accounting for two sides is set, is not reduced the length direction of RF tag 10, therefore do not influence RF tag
The length of the antenna surface of front and back does not just influence the electrical length of antenna surface yet.But setting installation card slot 121,122, it can
With the space of the setting receiving metal weld part in the space of installation card slot 121,122, thus by entire radio frequency mounting assembly
Volume reduces.
In the structure shown in Fig. 6, Fig. 7, the shape of RF tag 10 is that the side of left and right two removes semicircle on cuboid
The structure of columnar installation card slot.But the present invention is not limited thereto, in other embodiments, as shown in Fig. 8 (a), installation
The structure of card slot 121a, 122a can be rectangular parallelepiped space, and as shown in Fig. 8 (b), the structure for installing card slot 121b, 122b can be with
For square space, as shown in Fig. 8 (c), the structure of installation card slot 121c, 122c can be triangle body space.Such as Fig. 8 (a) to 8
(c), the electrical length H of each RF tag is from the side of dielectric base to the other side, not influenced by installation card slot.
In addition, the dielectric base of RF tag can carry installation card channel-shaped for cuboid shown in Fig. 6,7, can also be
