Connecting tube 13 in embodiment 1-4 is put it at identical conditions in the lab and contains germy sewage
In after 36 hours respectively take out be placed on microscopically observation the result is as follows:
| Embodiment | Observe result |
| Embodiment 1 | A large amount of bacteriums are distributed in the surface of connecting tube 13 |
| Embodiment 2 | Small amount bacterium is distributed in the surface of connecting tube 13 |
| Embodiment 3 | Small amount bacterium is distributed in the surface of connecting tube 13 |
| Embodiment 4 | Small amount bacterium is distributed in the surface of connecting tube 13 |
The bacterium of the surface distribution of connecting tube 13 in embodiment 2-4 is carried out further it was found that in embodiment 3
The bacterium of the surface distribution of connecting tube 13 is minimum, therefore embodiment 3 is optimum embodiment, by using above-mentioned technical proposal, system
The processing step of standby protective coating is simple, easy to accomplish, and the protective coating modest viscosity of preparation is not easy to be layered, is convenient for spraying, nothing
Bubble generates, each component sufficiently combines, and comprehensive performance is preferable, so that protective coating is capable of forming preferable film after spray coating,
It is not likely to produce crackle, film-formation result is preferable, and the protective layer of preparation has preferable anti-corrosion, fungi-proofing, anti-aging performance, adhesion
Preferably, not easily to fall off, anti-corrosion, fungi-proofing, the anti-aging performance of connecting tube 13 can be effectively increased, significantly can effectively be dropped
The probability that patient's connected tube 13 infects in low art.
Working principle: the universal blue pincers, hand-held portion 1 are used to hold and operate cutout unit 3 using hand,
By mounting rack 4, the first linking arm 6, the first grip ring 8, attachment base 20,21 structure of the second linking arm 7, the second grip ring 9 and connection sheet
At can be convenient insert a finger into the first grip ring 8 and the inside of the second grip ring 9 the first linking arm of cooperation 6 and the second company simultaneously in this way
It connects arm 7 and makes full use of lever principle, it is ensured that the excision dynamics of cutout unit 3, to guarantee smoothly to cut away the meniscus of lesion；
Connection adjustment portion 2 is used to adjust direction locating for cutout unit 3 for cutout unit 3 to be connected with hand-held portion 1, by
Installing pipe 12, nut 11, adjusts bolt 14, limit plate 31, the first disk 23 and the composition of steel wire 19 at connecting tube 13, can pass through
Steel wire 19 is driven, simultaneously because steel wire 19 is rotatably connected with limit plate 31 and through slot 22, therefore can be adjusted by unscrewing
Bolt 14 carries out 360 deg rotation to installing pipe 12 and adjusts, thus may be implemented to the meniscus of any orientation lesion into
Row excision, so that the range that indigo plant pincers can operate is larger；Cutout unit 3 by cutter seat 15, is cut for cutting off meniscus
Knife 16, fixed ear 26, the second disk 24, convex block 25, fixing seat 30, the first spring base 27, second spring seat 29 and spring 28,
Under the action of the spring 28, cutter 16 can keep open configuration with cutter seat 15 always in the case where no manual operation, simultaneously
So that steel wire 19 is in tensioning state, it can prevent the second grip ring 9 from shaking back and forth, so that not only structural behaviour is steady for indigo plant pincers
It is fixed and easy to use.
Application method: in use, first just finger is inserted into 8 He of the first grip ring by sterilizing operation, doctor respectively to indigo plant pincers
Inside second grip ring 9, then the cutout unit 3 of indigo plant pincers is put into half to intra-articular lesion by the notch at patient articular
Month plate carries out removal procedure, when excision, the meniscus of lesion is caught between cutter seat 15 and cutter 16, the finger force of doctor
Quick hold with a firm grip the first grip ring 8 and the second grip ring 9 drive cutter 16 to be engaged to cutter seat 15 by the meniscus of lesion by steel wire 19
It is cut off, then the meniscus of the lesion of excision is taken out, wrapping processing then is carried out to the notch of patient.
Part is not directed in the present invention to be the same as those in the prior art or can be realized by using the prior art.This specific implementation
Example is only explanation of the invention, is not limitation of the present invention, those skilled in the art are reading this specification
It can according to need the modification that not creative contribution is made to the present embodiment afterwards, but as long as in scope of the presently claimed invention
Inside all by the protection of Patent Law.
