When the needle head is connected with the syringe barrel through interference fit or material elasticity. Referring to fig. 10, the needle is inserted into the small holding hole 132 through the small needle hole 121, the operation rod 3 and the handle 2 are pinched, and the operation rod 3 drives the driving head 32 to move upwards due to the lever principle; the driving head 32 drives the moving sleeve 14 to move upwards; the moving sleeve 14 compresses the telescopic sleeve 13, so that the telescopic sleeve 13 clamps the needle. The syringe barrel is then withdrawn and if the force of the needle engaging the syringe barrel is low, the syringe barrel can be withdrawn and the needle separated from the syringe barrel. If the connecting force between the needle head and the syringe barrel is large, the end cover 12 is rotated, the end cover 12 moves outwards to be propped against the syringe barrel, the syringe barrel can be propped out, and the separation of the needle head and the syringe barrel is also realized; the needle is clamped to the sharp instrument box continuously, the operating rod 3 is loosened, the moving sleeve 14 is reset by the spring 15, the telescopic sleeve 13 rebounds, and the needle can fall into the sharp instrument box after being clamped.
When the needle head is connected with the syringe barrel through the screw thread, the operating rod 3 is pinched, the telescopic sleeve 13 clamps the needle head, and then the syringe barrel is rotated to separate the needle head from the syringe barrel.
When removing a large needle, such as an insulin syringe needle. As shown in fig. 11, the needle is passed through the large needle hole 112 into the large holding hole 131; then the operating rod 3 is pinched, and the needle head is clamped by the telescopic sleeve 13; the needle can then be separated from the syringe barrel by rotating the syringe barrel.
The operating rod 3 and the handle 2 are pinched tight by the cutting structure 5, the driving head 32 drives the movable sleeve 14 to move upwards, the movable cutting structure 52 connected with the movable sleeve 14 moves upwards, and finally the movable cutting structure is folded with the fixed cutting structure 51, so that the infusion tube can be cut off, and a scalp needle can be cut off.
The hole of the outer sleeve 11 connected with the end cover 12 can be filled with the telescopic sleeve 13, the movable sleeve 14 and the spring 15. The end cap 12 functions to also provide the rotary ejector syringe barrel function described above in addition to the closure sleeve 11. The spring 15 should be a compression spring so that the spring back can reset the movable sleeve 14, thereby resetting both the telescopic sleeve 13 and the operating rod 3 for facilitating the next clamping. When the spring 15 is rebounded to the limit, the movable sleeve 14 preferably still keeps pressing the telescopic sleeve 13, so that the telescopic sleeve 13 is slightly compressed. During needle removal, the drive head 32 moves a small amount along the drive head bore 141 and rotates a small amount. The driving groove 111 allows the driving head 32 to be fitted therein and allows the operation lever 3 to rotate without interfering with the outer casing 11. The shear structure slots 113 allow the dynamic shear structure 52 to be coupled to the moving sleeve 14 and allow the dynamic shear structure 52 to move without interference from the outer sleeve 11.
During clamping, a needle head is arranged in the telescopic sleeve 13, the telescopic sleeve 13 can only be reduced to the clamping needle head, and the shearing structure 5 is not folded at the moment, so that unnecessary abrasion is avoided. During shearing, no needle head is arranged in the telescopic sleeve 13, the telescopic sleeve 13 can be contracted to be smaller, and the shearing structure 5 can be folded to realize shearing.
In order to further improve the safety of the cutting structure 5, as shown in fig. 8, the fixed cutting structure 51 comprises a fixed cutting blade 511 and a fixed protective sleeve 512, the fixed protective sleeve 512 is connected with the outer sleeve 11, and the fixed cutting blade 511 is detachably connected with the fixed protective sleeve 512; the dynamic shear structure 52 comprises a dynamic shear blade 521 and a dynamic protective sleeve 522, the dynamic protective sleeve 522 is connected with the movable sleeve 14, and the dynamic shear blade 521 is detachably connected with the dynamic protective sleeve 522. So configured, the cutting structure 5 is not easily injured due to the protection of the stationary protective sleeve 512 and the protective sleeve 522, and the stationary cutting blade 511 and the movable cutting blade 521 can be replaced.
The specific structure of the telescopic sleeve 13 can be as shown in fig. 4 and 5, the telescopic sleeve 13 is provided with a plurality of first deformation grooves 133 and a plurality of second deformation grooves 134, the first deformation grooves 133 extend from the large end to the small end of the telescopic sleeve 13, the second deformation grooves 134 extend from the small end to the large end of the telescopic sleeve 13, and the first deformation grooves 133 and the second deformation grooves 134 are circumferentially and uniformly distributed and alternately arranged. Due to the presence of the first deforming groove 133 and the second deforming groove 134, the bellows 13 is compressible and resiliently springs back against the elasticity of its material. For sufficient service life and holding capacity, the telescopic sleeve 13 should be made of steel, particularly preferably spring steel with good elasticity. The force required by the compression of the telescopic sleeve 13 is large.
The specific structure of the telescopic sleeve 13 can also be as shown in fig. 6 and 7, the telescopic sleeve 13 comprises a plurality of telescopic sleeve assemblies 135 and a plurality of elastic bodies 136, the telescopic sleeve assemblies 135 are circumferentially and uniformly distributed and arranged at intervals, and the elastic bodies 136 are arranged between adjacent telescopic sleeve assemblies 135 and connected with the telescopic sleeve assemblies 135. At this time, since the elastic body 136 is compressible, the elastic sleeve 13 is compressible and rebounds by the elasticity of the elastic body 136. The elastomer 136 is preferably a hollow rubber body. Also for sufficient life and grip, the telescoping sleeve assembly 135 should be made of steel, however, since the telescoping sleeve assembly 135 does not require elasticity, the telescoping sleeve assembly 135 should be made of steel with good wear resistance. The telescopic sleeve 13 of the structure works by means of the elasticity of the elastic body 136, and the elastic body 136 is easy to compress, so that the force required by the compression of the telescopic sleeve 13 of the structure is small, and the relative effect is better.
To improve the safety of the present application, the needle detaching device comprises a protective cover 4; the protective cover 4 can be fitted over either end of the outer jacket 11. Application clamping structure is located overcoat 11 completely to the syringe needle of dismantlement can be covered to safety cover 4, and consequently this application practical safety is far above conventional pliers.
Also for sufficient life and grip, the shift sleeve 14 should have sufficient wear resistance. The moving sleeve 14 may be made of steel. The preferred shift sleeve 14 of the present application is shown in fig. 9 and includes a plastic sleeve 142 and a steel sleeve 143 with the drive head aperture 141 disposed in the steel sleeve 143.
Other friction-bearing or weak structures should be made of steel, such as the drive head 32 and the smaller diameter portion of the lever body 31. The structure with less stress, for the sake of weight reduction, is preferably made of plastic, such as the outer cover 11, the handle 2, the protective cover 4 and the thicker portion of the operating lever main body 31.
