[0002] Currently, bone cement is frequently used in clinical orthopedic surgery. When bone cement is implanted into the human body, it needs to be thoroughly mixed to meet the required mechanical properties. Traditional bone cement mixing methods involve manual mixing, which results in insufficient mixing and inconsistent mechanical properties of the implanted bone cement, affecting surgical and treatment outcomes.

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example:

[0031] like Figure 1-3 As shown, this embodiment provides a bone cement wheel system mixing mechanism, including a toothed cover 1, a mixing drive disc 2, and a mixer;

[0032] The agitator includes an agitator shaft 3, a gear 4, and an agitator 5. One end of the agitator shaft 3 is connected to the agitator 5. The gear 4 is located on the agitator shaft 3. The agitator 5 includes a placement space and a diverging spoke section 6. There are two or more diverging spoke sections 6 located in the placement space. A mixing space 7 is formed between adjacent diverging spoke sections 6 and between the diverging spoke sections 6 and the placement space.

[0033] The stirrer shaft 3 is rotated in conjunction with the stirring drive disc 2;

[0034] The tooth cover 1 meshes with the gear component 4.

[0035] In this embodiment, the bone cement wheel system mixing mechanism drives the mixing element 5 to rotate through the rotation of the mixing drive disk 2. Simultaneously, the rotation of the toothed cover 1 drives the mixing element 5 to rotate on its own axis, achieving the effect of dual rotation of the mixing element 5. During the rotation and revolution of the mixing element 5, the bone cement forms a ring-shaped vortex around the axis of the mixing element 5. At the same time, the diverging spokes 6, in conjunction with the structure of the mixing space 7, can divide and converge the fluid during the revolution and rotation of the mixing element, making the fluid turbulent and turbulent in the axial direction of the mixing element 5. This achieves rapid and thorough three-dimensional mixing of the bone cement in all directions, so as to fully realize the mechanical properties of the bone cement implanted in the human body and achieve and meet the purpose and efficacy of surgery and treatment.

[0036] The specific structure of the stirring component 5 in this embodiment is as follows:

[0037] The stirring component 5 also includes a first stirring connection part 8, a second stirring connection part 9, and an annular spoke part;

[0038] The first stirring connection part 8 is connected to the stirring shaft 3;

[0039] The annular spoke section has an arc-shaped structure and is connected to the first stirring connection section 8 to form a placement space. The second stirring connection section 9 is connected to the first stirring connection section 8 and is located in the placement space. The two ends of the diverging spoke section 6 are connected to the second stirring connection section 9 and the annular spoke section, respectively.

[0040] Specifically, the second stirring connection part 9 is coaxially arranged with the stirrer shaft 3.

[0041] Specifically, the annular spoke portion includes an annular spoke side portion 10, an annular spoke bottom portion 11, and an annular spoke arc portion 12. There are two annular spoke side portions 10, which are located on both sides of the annular spoke bottom portion 11. The annular spoke arc portion 12 is located between and connected to the annular spoke side portion 10 and the annular spoke bottom portion 11. The annular spoke side portion 10 is connected to the end of the first stirring connection portion 8.

[0042] Specifically, one end of the diverging spoke portion 6 is connected to the arc-shaped portion 12 of the annular spoke.

[0043] Specifically, there are two diverging spoke sections 6, the angle between the two diverging spoke sections 6 is a right angle, and the angle between the diverging spoke section 6 and the second stirring connection section 9 is an obtuse angle.

[0044] In the above structure, two diverging spoke sections 6 are located in the placement space and are respectively located on both sides of the second mixing connection section 9. The bone cement first forms an annular vortex around the axis of the mixing element 5 under the action of the annular spoke section and the diverging spoke section 6. During the revolution and rotation of the mixing element 5, the diverging spoke section 6 on one side, which is staggered, divides the fluid axially. The fluid passes through the mixing space 7 and then flows back together. The diverging spoke section 6 on the other side continues to divide the flowing fluid, and the fluid flows back together. Therefore, the fluid is repeatedly divided axially and flowed back together by the diverging spoke section 6, so that the fluid is in a turbulent and turbulent state in the axial direction of the mixing element 5.

[0045] Meanwhile, the annular spoke section has an arc-shaped section 12, which can ensure the smoothness of bone cement mixing and ensure that the bone cement can flow stably.

[0046] In this embodiment, the stirring drive disk 2 is provided with an eccentric shaft hole 13 that rotates with the stirrer shaft 3. The stirrer shaft 3 is provided with an annular groove 14 that mates with the eccentric shaft hole 13. The shaft diameter of the stirrer shaft 3 is larger than the diameter of the eccentric shaft hole 13. An annular protrusion 15 is provided in the eccentric shaft hole 13, and the annular protrusion 15 is located in the annular groove 14.

[0047] The above structure ensures that the agitator shaft 3 is stably fixed to the agitator drive disc 2.

[0048] Specifically, the tooth cover 1 has an annular internal rack portion that meshes with the gear component 4.

[0049] This embodiment also includes a bone cement mixer, comprising a housing 16, a drive device 17, a mixing chamber 18, and the aforementioned bone cement wheel system mixing mechanism. The drive device 17 and the bone cement wheel system mixing mechanism are located inside the housing 16. The drive end of the drive device 17 is connected to the toothed cover 1 and the mixing drive disc 2, respectively. The mixing component 5 is located inside the mixing chamber 18.

[0050] Specifically, the toothed cover 1 and the stirring drive disc 2 are coaxially arranged, and the drive device 17 is a drive motor.

[0051] In the above structure, the mixing chamber 18 is used to hold bone cement, and the driving end of the driving device 17 is used to drive the toothed cover 1 and the mixing drive disk 2 to rotate, thereby achieving the above-mentioned mixing effect on the bone cement.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
