Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary appliances, and in particular to a spiral bone powder conveyor. Background Art

[0002] With the advancement and development of science and technology, the technology and related equipment related to dental care and treatment are also booming. In the process of implanting artificial tooth roots, different amounts of bone powder will be filled into the patient's alveolar bone according to the health of the patient's gums, so as to repair and strengthen the structure of the patient's gums and ensure that when the artificial tooth roots are implanted in the patient's gums, they can be firmly set on the patient's alveolar bone. The types of bone powder can be roughly divided into artificial bone powder, autologous bone powder, allogeneic bone powder, animal bone powder and other types. Artificial bone powder is made by synthesizing chemical materials, autologous bone powder is made by taking out the patient's own bones (such as skull, kneecap or thigh tibia, etc.), allogeneic bone powder is made from human bones of donors, and animal bone powder is made from animal bones such as pig bones and cow bones.

[0003] Currently, during the dental implant process, when bone powder is used for filling, periosteal strippers, digging spoons and other instruments are often used to transport the bone powder to the gap or bone defect. This not only makes the delivery of bone powder at the bottom of the implant socket difficult and difficult to control, but also conventional conveyors have to take the bone powder out of the outlet and reload it with bone powder after each delivery, resulting in low efficiency and troublesome bone powder delivery. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a spiral bone powder conveyor to solve the problem that in the existing dental implant process, periosteal strippers, digging spoons and other instruments are often used to convey bone powder to the gap or bone defect, which not only makes the bone powder conveying at the bottom of the implantation hole difficult and difficult to control, but also has low conveying efficiency and is troublesome to convey bone powder.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A spiral bone powder conveyor comprises a shell, a bone powder collecting bucket is fixedly connected to the left side of the upper surface of the shell, a conveying cylinder is fixedly connected to the left interior of the shell, the bone powder collecting bucket and the conveying cylinder are connected through a connecting cylinder, a discharge nozzle is installed on the left side of the conveying cylinder, a rotating shaft is rotatably connected between the inner walls of the left and right sides of the conveying cylinder through a bearing, and a feeding spiral is fixedly connected to the outer surface of the rotating shaft;

[0007] A round rod and a worm are rotatably connected between the front and rear inner walls of the shell through bearings, a large gear and a movable handle are fixedly connected to the outer surface of the round rod, a torsion spring is sleeved and installed between the outer surface of the round rod and the inner wall of the shell, the bottom end of the movable handle is located outside the shell, a fixed handle is fixedly connected to the right side of the lower surface of the shell, a small gear is rotatably connected to the outer surface of the worm through a one-way bearing, the small gear is meshingly connected to the large gear, the right end of the rotating shaft is located inside the shell and fixedly connected to a worm wheel, and the worm is meshingly connected to the worm wheel.

[0008] Preferably, a cover plate is rotatably mounted on the right side of the upper surface of the bone powder collecting bucket via a hinge, and a handle is fixedly connected to the left side of the upper surface of the cover plate.

[0009] Preferably, the cross section of the conveying tube is circular, and the conveying tube is made of a transparent material.

[0010] Preferably, a stirring assembly is provided inside the connecting cylinder, and the stirring assembly is used to deliver the bone powder in the bone powder collecting bucket into the conveying cylinder.

[0011] Preferably, the stirring assembly includes a rotating shaft rotatably connected to the inner walls on the left and right sides of the connecting cylinder through bearings, the outer surface of the rotating shaft located inside the connecting cylinder is fixedly connected to a plurality of stirring blades, the right side of the rotating shaft is located inside the shell and is fixedly connected to a first gear, the right side of the rotating shaft is fixedly connected to a second gear, and the first gear is meshingly connected to the second gear.

[0012] Preferably, a communication hole is formed on the inner top wall of the shell, and the communication hole corresponds to the position of the stirring blade.

[0013] Preferably, the inner wall of the bone powder collecting hopper is in a conical structure, and the inner bottom wall of the bone powder collecting hopper is inclined toward the connecting tube.

[0014] Preferably, the discharge nozzle is a bent structure, and the discharge nozzle is rotatably mounted on the left side of the conveying cylinder.

[0015] Preferably, a threaded column is fixedly connected to the left bottom end of the conveying cylinder, a through hole connected to the conveying cylinder is opened inside the threaded column, a sealing ring is installed inside the through hole, a retaining ring is fixedly connected to the outer surface of the discharge nozzle and is sleeved with a threaded sleeve, the right end of the discharge nozzle is inserted into the through hole, and the threaded sleeve is threadedly connected to the threaded column.

The second gear can cooperate with the first gear to drive the rotating shaft and multiple stirring blades to rotate during the rotation. The stirring blades can break up the agglomerated materials during the rotation to prevent large pieces of material from clogging the discharge nozzle and jamming the feeding screw, thereby making the conveying more stable during use.

[0019] In the above scheme, bone powder is added into the bone powder collecting bucket, and the bone powder will fall into the conveying cylinder. Then, the movable handle and the fixed handle are held and applied force. At this time, the movable handle drives the feeding screw to rotate and compresses the torsion spring. During the rotation, the feeding screw can convey the fallen bone powder to the discharge nozzle. Then, the movable handle is released. At this time, the restoring force of the torsion spring drives the round rod, the large gear and the small gear to rotate in the opposite direction and reset. Since the small gear is rotatably connected to the outer surface of the worm through a one-way bearing, the feeding screw will not rotate at this time. Then, force is continued on the movable handle, and the above steps are repeated. The bone powder can be discharged from the discharge nozzle through the continuous rotation of the feeding screw, thereby conveying the bone powder to the gap or bone defect through the discharge nozzle. It is not only easy to control, but also has high conveying efficiency, and it is very convenient to convey bone powder. BRIEF DESCRIPTION OF THE DRAWINGS

Since the small gear 13 is rotatably connected to the outer surface of the worm 9 through a one-way bearing, the small gear 13 will not drive the worm 9, the rotating shaft 6 and the feeding screw 7 to rotate during the rotation. Then continue to apply force to the movable handle 11 and repeat the above steps.
