Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a spiral bone cement booster. Background Technology

[0002] A bone cement pusher (or bone cement auger) is a medical device used in orthopedic surgery to push bone cement from a tube to the desired location. The pusher mainly consists of a pusher body, tube clamps, sealing gaskets, and a clamp wrench. These components work together to ensure that the bone cement is accurately and quickly delivered to the surgical site.

[0003] Current bone cement boosters, during installation and use by users, still have the following shortcomings:

[0004] (1) Most existing bone cement pushers use manual extrusion mode to push bone cement, and the amount of bone cement squeezed out varies with the force of each extrusion. This not only increases the labor intensity of manual labor, but also makes it impossible to obtain the precise amount of bone cement injected.

[0005] (2) Most existing bone cement boosters do not have a mixing mechanism. They need to be mixed manually outside the device before being added to the booster. This process involves multiple containers, which not only wastes a lot of time but may also lead to material waste and increased production costs. Utility Model Content

[0006] In order to overcome the defects of the prior art as mentioned above, the inventors of this utility model have conducted in-depth research and, after a great deal of creative work, have completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a spiral bone cement pusher to solve the problem that most current bone cement pushers use a manual squeezing mode to push bone cement, and the amount of bone cement squeezed out varies with the squeezing force each time. This not only increases the labor intensity of manual labor, but also makes it impossible to obtain a precise injection amount of bone cement.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A spiral bone cement pusher includes a pusher body, an injection tube at one end of the pusher body, a first switch inside the injection tube, a spiral pusher assembly inside the pusher body, a mixing assembly on the outer surface of the pusher body, and a handle assembly opposite the mixing assembly on the outer surface of the pusher body.

[0010] The spiral booster assembly includes a booster cavity located inside the booster body. A piston is provided inside the booster cavity, and a rotating seat is provided on one side of the piston. A driving mechanism is provided on the rotating seat, and an observation mechanism is provided on the outer surface of the booster body.

[0011] As an improved technical solution, the driving mechanism includes a threaded rod that is threadedly connected to the booster body. One end of the threaded rod is provided with a limiting plate, which is located inside the rotating seat. The rotating seat is rotatably connected to the threaded rod, and the other end of the threaded rod is provided with a turntable.

[0012] As an improved technical solution, the observation mechanism includes an observation window, which is opened on the outer surface of the booster body, and the observation window is provided with several scale lines.

[0013] As an improved technical solution, the mixing assembly includes a mixing tank, a U-shaped plate on the top of the mixing tank, a motor on the top of the U-shaped plate, a main stirring shaft connected to the output end of the motor, the main stirring shaft extending into the mixing tank, a plurality of main stirring blades on the main stirring shaft, a secondary stirring shaft symmetrically arranged on the top of the booster body, a plurality of secondary stirring blades on the secondary stirring shaft, and a connecting mechanism on the main stirring shaft.

[0014] As an improved technical solution, the observation mechanism includes a first gear, which is mounted on the main stirring shaft, and a second gear is mounted on the auxiliary stirring shaft, wherein the first gear and the second gear mesh accordingly.

[0015] As an improved technical solution, the mixing tank is provided with a discharge pipe at the bottom, a second switch on the discharge pipe, a power supply at the top of the mixing tank, a feed inlet at the top of the mixing tank, and the power supply and the feed inlet are distributed on both sides of the U-shaped plate, and an end cap is provided at the top of the feed inlet.

[0016] As an improved technical solution, the grip assembly includes a lower grip, which is disposed on the outer surface of the booster body, and limit grooves are respectively formed on both sides of the lower grip.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the turntable drives the threaded rod to rotate, and the threaded rod drives the limiting plate to move along the booster body. The limiting plate pushes the piston to move closer to the injection tube through the rotating seat. The piston squeezes the bone cement out of the injection tube. The amount of bone cement squeezed can be accurately obtained through the scale line. There is no need for manual squeezing, which not only reduces the labor intensity of manual labor, but also allows for observation of the precise injection amount of bone cement.

[0019] 2. In this utility model, a motor drives several main stirring blades on the main stirring shaft to rotate. The main stirring shaft drives a second gear to rotate via a first gear. The second gear drives several auxiliary stirring blades on the auxiliary stirring shaft to rotate. The main stirring blades and auxiliary stirring blades thoroughly mix the raw materials and medicine in the mixing tank. Then, the second switch is turned on to inject the bone cement into the inner cavity of the booster. There is no need for manual operation between multiple containers, which not only saves a lot of time but also avoids material waste and reduces production costs.

[0020] 3. This utility model has a lower handle that makes it easy for workers to pick up, and a limiting groove that increases friction, making it less likely for workers to slip during operation. Attached Figure Description

[0031] like Figure 1 and Figure 3As shown in the figure, this embodiment provides a spiral bone cement booster, including a booster body 1, an injection tube 2 at one end of the booster body 1, a first switch 3 inside the injection tube 2, a spiral booster assembly 4 inside the booster body 1, a mixing assembly 5 on the outer surface of the booster body 1, and a handle assembly 6 opposite to the mixing assembly 5 on the outer surface of the booster body 1.

[0032] The spiral booster assembly 4 includes a booster cavity 41, which is located inside the booster body 1. A piston 42 is provided inside the booster cavity 41, and a rotating seat 43 is provided on one side of the piston 42. A drive mechanism is provided on the rotating seat 43. An observation mechanism is provided on the outer surface of the booster body 1. The piston 42 is pushed by the drive mechanism to move closer to the injection tube 2, and the bone cement is squeezed out of the injection tube 2 by the piston 42. There is no need for manual squeezing, which reduces the labor intensity of manual labor.

[0033] The drive mechanism includes a threaded rod 441, which is threadedly connected to the booster body 1. One end of the threaded rod 441 is provided with a limiting plate 442, which is located inside the rotating seat 43. The rotating seat 43 is rotatably connected to the threaded rod 441. The other end of the threaded rod 441 is provided with a turntable 443, which drives the threaded rod 441 to rotate. The threaded rod 441 drives the limiting plate 442 to move along the booster body 1. The limiting plate 442 pushes the piston 42 towards the injection tube 2 through the rotating seat 43, thereby realizing the transmission of motion.

[0034] The observation mechanism includes an observation window 451, which is located on the outer surface of the booster body 1. The observation window 451 is provided with several scale lines 452, through which the amount of bone cement extrusion can be accurately determined.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the mixing assembly 5 includes a mixing tank 51, a U-shaped plate 52 on the top of the mixing tank 51, a motor 53 on the top of the U-shaped plate 52, and a main stirring shaft 54 ​​whose output end is connected to the main stirring shaft 54. The main stirring shaft 54 ​​extends into the mixing tank 51, and a number of main stirring blades 55 are provided on the main stirring shaft 54. A secondary stirring shaft 56 is symmetrically provided on the top of the booster body 1, and a number of secondary stirring blades 57 are provided on the secondary stirring shaft 56. A connecting mechanism is provided on the main stirring shaft 54. The main stirring blades 55 and the secondary stirring blades 57 are used to fully mix the raw materials and medicine in the mixing tank 51, eliminating the need for manual operation between multiple containers and saving a lot of time.

[0036] The observation mechanism includes a first gear 58, which is mounted on the main stirring shaft 54. A second gear 59 is mounted on the auxiliary stirring shaft 56. The first gear 58 and the second gear 59 mesh with each other. The main stirring shaft 54 ​​drives the second gear 59 to rotate through the first gear 58. The second gear 59 drives several auxiliary stirring blades 57 on the auxiliary stirring shaft 56 to rotate, thus realizing the transmission of motion.

[0037] The bottom of the mixing tank 51 is provided with a feeding pipe 510, and a second switch 511 is provided on the feeding pipe 510. The top of the mixing tank 51 is provided with a power supply 512, and the top of the mixing tank 51 is provided with a feed inlet 513. The power supply 512 and the feed inlet 513 are distributed on both sides of the U-shaped plate 52. The top of the feed inlet 513 is provided with an end cap 514. The power supply 512 supplies power to the motor 53, and the raw materials and medicine are added to the mixing tank 51 through the feed inlet 513.

[0038] like Figure 1 and Figure 2 As shown, the grip assembly 6 includes a lower grip 61, which is located on the outer surface of the booster body 1. Limiting grooves 62 are respectively opened on both sides of the lower grip 61. The lower grip 61 makes it easy for the operator to pick up the device, and the limiting grooves 62 can increase the friction, making it less likely for the operator to slip during operation.

[0039] During use, the operator adds the raw materials and medicine into the mixing tank 51 through the feed inlet 513. Then, the motor 53 is started, driving several main stirring blades 55 on the main stirring shaft 54 ​​to rotate. The main stirring shaft 54 ​​drives the second gear 59 to rotate via the first gear 58. The second gear 59 drives several auxiliary stirring blades 57 on the auxiliary stirring shaft 56 to rotate. The main stirring blades 55 and auxiliary stirring blades 57 thoroughly mix the raw materials and medicine in the mixing tank 51. Then, the first switch 3 and the second switch 511 are opened to inject bone cement into the booster cavity 41. This eliminates the need for manual operation between multiple containers, saving significant time, avoiding material waste, and reducing [the risk of infection / damage]. To reduce production costs, the turntable 443 is rotated, which drives the threaded rod 441 to rotate. The threaded rod 441 moves along the booster body 1, causing the limiting plate 442 to move. The limiting plate 442 pushes the piston 42 towards the injection tube 2 through the rotating seat 43. The piston 42 squeezes the bone cement out of the injection tube 2. The amount of bone cement squeezed can be accurately determined through the scale line 452. There is no need for manual squeezing, which not only reduces the labor intensity of manual labor, but also allows for observation of the precise injection amount of bone cement. When operating, the operator needs to hold the lower handle 61. The lower handle 61 makes it easy for the operator to pick up the bone cement. The limiting groove 62 increases the friction, making it less likely for the operator to slip during operation.
