Description

Technical Field

[0001] The utility model relates to the technical field of stirring tools, in particular to a stirring and smearing tool. Background Art

[0002] In the medical field, the mixing and stirring treatment of two-component or multi-component medical adhesives usually requires the use of a stirring tool. However, in order to provide sufficient shear force to ensure that materials with high viscosity can be fully and evenly mixed, the shape of traditional stirring tools is not suitable for use as a smearing tool. Therefore, in actual operation, it is usually necessary to additionally use a special smearing tool to smear the adhesive. However, since the adhesive thickens after stirring and curing, if an additional brush is used for smearing, not only will the adhesive material adsorbed by the stirring rod itself be wasted, but also time may be delayed due to the replacement and fixing process on the machine, resulting in the adhesive being too viscous to be smeared and used, and increasing the cost and the possibility of pollution of medical materials. In addition, the materials of some stirring tools have poor compatibility with the stirring materials, which not only affects the mixing quality but also may contaminate the stirring materials.

[0023] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0024] A stirring and smearing tool in this embodiment, referring to the attached Figure 1 、 2 5 includes a stirring rod body 1, a brush head 2 and a connection structure 3. The brush head 2 is arranged at one end of the stirring rod body 1, and the connection structure 3 is arranged at the other end of the stirring rod body 1. The brush head 2 includes a support portion 21 and a silicone outer layer 22. The top end of the support portion 21 is connected to the stirring rod body 1, the bottom of the support portion 21 is in a linear structure, and the silicone outer layer 22 covers the outside of the support portion 21. The connection structure 3 is used to connect with the rotating shaft end of an electric mixer.

[0025] The stirring and smearing tool in this embodiment realizes the combination of stirring and smearing functions by respectively arranging the brush head 2 and the connection structure 3 at both ends of the stirring rod body 1. When connected to an electric mixer, it can achieve stable shear mixing under the high-torque rotation of the motor, and is suitable for the uniform mixing and curing of two-component or multi-component medical adhesives, and can provide greater shear force and higher mixing efficiency for materials with high viscosity. The support portion 21 has the function of mechanically supporting the silicone outer layer 22 and also has a lower hardness, so that the tissue will not be scratched during the smearing process. In addition, the silicone outer layer 22 is used to cover the outside of the support portion 21. Utilizing the chemical stability of the silicone material, it has good compatibility with the stirring material and can be reused. After stirring, it can also be used as an adhesive smearing tool. The stirring rod has strong supporting ability and can bring out the adhesive material with higher viscosity, making it more convenient to use.

[0026] Preferably, inclined sections 222 are arranged outwardly on the left and right sides of the silicone outer layer 22, and inclined surfaces 223 are arranged inwardly on the front and back sides of the silicone outer layer 22, that is, the thickness of the front and back sides of the support portion 21 gradually increases from bottom to top. Thus, by arranging the inclined sections 222 outwardly on the left and right sides of the silicone outer layer 22, the surface area of the front and back sides of the silicone outer layer 22 is increased, that is, the surface area of the inclined surfaces 223 is increased, so that the contact area with the stirring material is increased during the stirring process, and the stirring efficiency is higher. By making the thickness of the front and back sides of the support portion 21 gradually increase from bottom to top, the phenomenon of breakage during the stirring of substances with high viscosity or resistance is avoided.

[0027] Furthermore, referring to the attached Figure 3, a first chamfering portion 224 is provided between the inclined section 222 and the bottom 221 of the silicone outer layer 22. By providing the first chamfering portion 224, problems such as scratches easily generated during the brushing process of the brush head 2 and high brushing thickness on both sides are avoided.

[0028] Further, referring to the attached Figure 4 , a second chamfering portion 225 is provided between the inclined surface 223 and the bottom 221 of the silicone outer layer 22. By providing the second chamfering portion 225, the coating thickness during the application process of the brush head 2 is ensured to be uniform.

[0029] Preferably, the cross-sectional area of the top end of the support portion 21 is smaller than the cross-sectional area of one end of the stirring rod body 1, and the outer sides of the silicone outer layer 22 and the stirring rod body 1 are flush with each other up and down. By setting the cross-sectional area of the top end of the support portion 21 to be smaller than the cross-sectional area of one end of the stirring rod body 1, a horizontal distance difference exists between the outer side of the support portion 21 and the outer side of the stirring rod body 1, so that the outer side of the silicone outer layer 22 is flush with the outer side of the stirring rod body 1 after molding, thereby making the bonding between the silicone and the plastic more firm, there are no scratches at the splicing place, and the risk of deformation or detachment of the silicone outer layer 22 during high-speed stirring is prevented.

[0030] Preferably, the thickness of the silicone outer layer 22 is 0.25 - 0.5 mm. By using the silicone outer layer 22 with a thickness of 0.25 - 0.5 mm, not only can a good shearing force for stirring viscous substances be provided, but also the thickness of the silicone outer layer 22 is relatively low. Cooperating with the stirring rod body 1 can provide a better stirring effect, making the silicone outer layer 22 not easily deformed, and at the same time, it is not easy to scratch the tissue when applying on the tissue, and the tissue-fitting effect is better.

[0031] Preferably, the connecting structure 3, the stirring rod body 1, and the support portion 21 are integrally made of polycarbonate (PC), polyvinyl chloride (PVC), or polypropylene (PP) materials. By using PC or PVC or PP materials to integrally make the connecting structure 3, the stirring rod body 1, and the support portion 21, the stability and durability of the overall structure are improved, and the support for high-speed stirring can be realized.

[0032] Preferably, the connecting structure is a hexagonal connecting structure 3. By using the connecting structure of the hexagonal connecting structure 3, it is convenient for the stirring and applying tool of this embodiment to be connected to the rotating shaft end of the electric mixer, and the function of high-speed stirring can be realized.

[0033] Preferably, the length of the silicone outer layer is 1 / 2 - 1 / 4 of the length of the stirring rod body. Contact between the stirring rod body and the liquid medicine is avoided. To ensure that when stirring or applying the adhesive, the silicone outer layer contacts the adhesive, while avoiding the stirring rod body directly contacting the adhesive.

[0034] Preferably, referring to the attached Figure 6A transition portion 31 is provided between the connection structure 3 and the stirring rod body 1. The transition portion 31 is a streamlined shape that gradually changes from a hexagonal connection structure to a cylindrical structure, that is, the size of the connection structure 3 gradually transitions to the size of the stirring rod body 1, which not only ensures the stability of the connection part, but also provides better fluidity during the injection molding process to avoid molding defects.

[0035] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
