Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a small-angle high-speed turbine handpiece. Background Art

[0002] The angle between the needle axis and the handle axis of existing turbine handpieces for dental treatment is generally more than 20°, which causes the handle of the handpiece to collide with the adjacent teeth of the tooth being extracted during tooth extraction, creating obstacles to tooth extraction. Once the angle between the needle axis and the handle axis is further reduced, the hose that supplies water to the handpiece will bend too much when entering the handpiece, resulting in limited water flow in the hose.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a small-angle high-speed turbine handpiece to solve the technical problems existing in the prior art.

[0006] The included angle between the rotation axis of the needle (21) and the axis of the handle body (1) is 5°-15°;

[0007] A water guiding channel is formed in the connecting section, and the water guiding channel extends to the water outlet end of the head assembly. The water guiding channel is formed during the processing of the connecting section, and the water guiding channel smoothly transitions toward the corner of the head assembly.

[0008] In an optional embodiment, a cavity is formed in the handle body, and the cavity extends from the grip section to the transition section.

[0012] In an optional embodiment, the water inlet end is connected to one end of a water hose, the water hose passes through the grip section and the cavity, and the other end of the water hose is connected to the water inlet of one end of the water channel away from the head assembly.

[0013] In an optional embodiment, the turbine is used to drive a needle in the nose assembly.

[0014] In an optional embodiment, a rear end water guiding channel is formed in the gripping section, the rear end water guiding channel extends to the cavity, and the rear end water guiding channel is formed during the processing of the gripping section.

[0015] In an optional embodiment, the water inlet of the rear end water guiding channel is connected to the water inlet end; the water outlet of the rear end water guiding channel is connected to the water inlet of the water guiding channel via a water guiding hose.

[0016] In an optional embodiment, an arc-shaped groove is formed on the surface of the gripping section for increasing friction.

[0032] Embodiment 1

[0033] Please see attached Figure 1-5 The purpose of this embodiment is to provide a small-angle high-speed turbine handpiece, comprising: a handle body 1, the front end of the handle body 1 is connected to the head assembly 2, and the turbine 22 in the head assembly 2 is used to drive the needle 21 in the head assembly 2. It should be pointed out that the angle between the rotation axis of the needle 21 and the axis of the handle body 1 is 5°-15°, which can effectively avoid the attachment Figure 6 As shown in the figure, during the tooth extraction process, the mobile phone handle collides with the adjacent tooth next to the tooth being extracted. In this embodiment, the angle between the rotation axis of the needle 21 and the axis of the handle body 1 is 10°.

[0034] Specifically, the handle body 1 is a connecting section 12, a transition section 16 and a gripping section 11 extending in sequence, and the sizes of the connecting section 12, the transition section 16 and the gripping section 11 increase in sequence. The gradually decreasing sizes of the connecting section 12 and the transition section 16 can effectively reduce the materials used in the production process of the mobile phone, thereby reducing the production cost of the mobile phone. A cavity 14 is formed in the handle body 1, and the cavity 14 extends from the gripping section 11 to the transition section 16, thereby further reducing the materials used in the production process of the mobile phone, thereby reducing the production cost of the mobile phone. The cavity 14 can also provide a storage space for the water hose described below, and can also provide a storage space for the air hose connecting the air inlet end 131 and the exhaust end 132, thereby reducing the overall weight of the mobile phone.

[0035] In this embodiment, a water channel 15 is formed in the connecting section 12, and the water channel 15 extends to the water outlet 152 on the head assembly 2. The water channel 15 is formed during the processing of the connecting section 12, and the water channel 15 smoothly transitions toward the corner 151 of the head assembly 2. The mobile phone naturally forms a water channel 15 during the processing of the handle, and the water channel 15 smoothly transitions toward the corner 151 of the head assembly 2 without any transition bends like a water hose. The water flows stably when passing through the corner 151, which can ensure that the flow rate is stable when the water flows through the corner 151, and can ensure sufficient flow rate, and can provide a stable water flow for the water outlet of the head assembly. It is worth mentioning that the water channel 15 is formed during the processing of the connecting section 12, which reduces the length of the water hose in the handle, and again saves the production cost of the mobile phone.

[0036] It should be pointed out that the tail of the handle body 1 is provided with an air inlet end 131, an exhaust end 132 and a water inlet end 133; the air inlet end 131 and the exhaust end 132 are used to provide air intake and exhaust for the turbine 22 in the handpiece assembly 2; the water inlet end 133 is used to provide a water source for the handpiece assembly 2. In this embodiment, the water inlet end 133 is connected to one end of a water hose, the water hose passes through the grip section 11 and the cavity 14, and the other end of the water hose is connected to the water inlet of the water channel 15 away from the end of the handpiece assembly 2. In addition, an arc groove for increasing friction is formed on the surface of the grip section 11, which is convenient for doctors to hold and use the mobile phone.

It should be pointed out that the angle between the rotation axis of the needle 21 and the axis of the handle body 1 is 15°, which can effectively avoid the attachment Figure 6 As shown in FIG. , during a tooth extraction process, the handpiece handle collides with an adjacent tooth immediately adjacent to the tooth being extracted.

[0039] Specifically, the handle body 1 is a connecting section 12, a transition section 16 and a gripping section 11 extending in sequence, and the sizes of the connecting section 12, the transition section 16 and the gripping section 11 increase in sequence. The gradually decreasing sizes of the connecting section 12 and the transition section 16 can effectively reduce the materials used in the production process of the mobile phone, thereby reducing the production cost of the mobile phone. A cavity 14 is formed in the handle body 1, and the cavity 14 extends from the gripping section 11 to the transition section 16, thereby further reducing the materials used in the production process of the mobile phone, thereby reducing the production cost of the mobile phone. The cavity 14 can also provide a storage space for the water hose described below, and can also provide a storage space for the air hose connecting the air inlet end 131 and the exhaust end 132, thereby reducing the overall weight of the mobile phone.

[0040] In this embodiment, a water channel 15 is formed in the connecting section 12, and the water channel 15 extends to the water outlet 152 on the head assembly 2. The water channel 15 is formed during the processing of the connecting section 12, and the water channel 15 smoothly transitions toward the corner 151 of the head assembly 2. The mobile phone naturally forms a water channel 15 during the processing of the handle, and the water channel 15 smoothly transitions toward the corner 151 of the head assembly 2. The water flow is stable when passing through the corner 151, which can ensure that the flow rate is stable when the water flows through the corner 151, and can ensure sufficient flow rate, and can provide a stable water flow for the water outlet of the head assembly. It is worth mentioning that the water channel 15 is formed during the processing of the connecting section 12, which reduces the length of the water hose in the handle, and again saves the production cost of the mobile phone.

[0041] It should be pointed out that the tail of the handle body 1 is provided with an air inlet end 131, an exhaust end 132 and a water inlet end 133; the air inlet end 131 and the exhaust end 132 are used to provide air intake and exhaust for the turbine 22 in the head assembly 2; the water inlet end 133 is used to provide a water source for the head assembly 2.

[0042] In this embodiment, a rear water-conducting channel is formed in the gripping section 11, and the rear water-conducting channel extends to the cavity 14. The rear water-conducting channel is formed during the processing of the gripping section 11. The water inlet of the rear water-conducting channel is connected to the water inlet end 133; the water outlet of the rear water-conducting channel is connected to the water inlet of the water-conducting channel 15 through a water-conducting hose. The rear water-conducting channel formed by processing is used again to replace part of the water-conducting hose, which further reduces the length of the water-conducting hose in the handle and reduces the production cost of the mobile phone. In addition, an arc groove for increasing friction is formed on the surface of the gripping section 11, which is convenient for doctors to hold and use the mobile phone.
