Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an orthodontic puller with a protective sleeve. Background Technology

[0002] Orthodontic retractors are frequently used by dental professionals. During dental treatments, they are used to open the lips and cheeks to examine the internal structures of the mouth or to check the health of the teeth and gums.

[0003] However, the orthodontic retractors commonly used at present are generally made of polycarbonate. Because orthodontic retractors made of polycarbonate are hard, they can cause strong pain when in contact with the patient's skin during mouth opening procedures. For some patients with dry lips, they can easily cause chapped lips or even bleeding. This not only causes discomfort to the patient, but the blood may also contaminate the oral cavity, teeth, and gums, affecting the diagnosis and treatment of the patient's oral cavity, teeth, and gums by medical staff.

[0004] For example, utility model CN221331293U discloses an orthodontic retractor with lubrication function, which relates to the field of dental medical device technology. It includes: a retractor body, a handle, and a labial groove. A portion of the retractor body is in contact with the teeth and gums, and the overall cross-section of the retractor body is U-shaped. The handle is located on the opposite side of the portion of the retractor body that is in contact with the teeth and gums, and the handle is a flattened structure with gradually increasing thickness. The labial groove is the inner surface of the retractor body, and a hollow sac is provided on the surface of the labial groove. Lubrication holes are evenly distributed on the surface of the hollow sac that abuts against the corner of the lip. Lubricating fluid is extracted from the lubrication holes by squeezing, thus lubricating the skin at the corner of the lip.

[0005] However, this structure acts on the lips, requiring precise manual release of lubricant. If too little is released, the lubricating effect is minimal; if too much is released, it may enter the patient's oral cavity, causing discomfort or injury. Furthermore, existing orthodontic hooks have limited functionality, especially when suctioning saliva, requiring frequent suction tube manipulation, which is cumbersome, impacting work efficiency and patient experience. Therefore, there is an urgent need for a simpler and more functional orthodontic hook. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology, which protects the lip corner by releasing lubricant, which is inconvenient to control the amount of lubricant released, difficult to operate and has limited function, and to provide an orthodontic puller with a protective sleeve.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An orthodontic puller with a protective sleeve includes two puller bodies and a U-shaped fixing frame, wherein the puller bodies are fixed to both ends of the U-shaped fixing frame.

[0009] The hook body has a slot on one side that matches the shape of the corner of the mouth, and a silicone protective sleeve is provided in the slot; the hook body and the U-shaped fixing frame have interconnected flow channels, the hook body has an opening on the side away from the slot, a saliva suction tube is installed on the opening, the saliva suction tube is connected to the flow channel, and the flow channel of the U-shaped fixing frame is connected to the negative pressure component.

[0010] Preferably, the silicone protective sleeve has a crescent-shaped curved surface structure and is fitted to the side wall of the slot. The two ends of the silicone protective sleeve are provided with snap-fit ​​grooves that cooperate with the two ends of the hook body. The snap-fit ​​grooves are snapped into the two ends of the hook body.

[0011] Preferably, the silicone protective sleeve has evenly distributed heat dissipation holes.

[0012] Preferably, the saliva suction tube is a flexible tube.

[0013] Preferably, there are multiple saliva suction tubes, and each saliva suction tube is evenly distributed on the hook body.

[0014] Preferably, the length of the suction tubes at both ends of the hook body is less than the length of the suction tube in the middle section.

[0015] Preferably, the saliva suction tube is a bendable bamboo tube.

[0016] Preferably, the end of the saliva suction tube away from the hook body is provided with a filter ball, and the surface of the filter ball is provided with multiple filter holes, each filter hole being evenly distributed on the surface of the filter ball.

[0017] Preferably, the U-shaped fixing frame is provided with a drainage tube, one end of which is installed on the U-shaped fixing frame and the other end is connected to the negative pressure component.

[0018] Preferably, one end of the drainage tube is threaded to a U-shaped fixing bracket, and a filter screen is provided inside the end near the U-shaped fixing bracket.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) This solution uses a silicone protective sleeve inside the groove where the hook body contacts the corner of the lip to prevent the corner of the lip from contacting hard materials. Based on the elasticity and flexibility of the silicone protective sleeve, the corner of the lip is effectively protected.

Moreover, a flow channel is set inside the hook body, which, together with the saliva suction tube connected to the flow channel on one side of the hook body, reduces the difficulty of the doctor's oral examination, improves the overall efficiency and the patient's user experience, and has strong practicality.

[0021] (2) This solution has a variety of lengths of suction tubes inside the hook body and adopts a bendable and shape-fixed bamboo tube design, which can perform suction in multiple positions in the oral cavity, ensuring the reliability of suction. Compared with the suction operation performed by the doctor alone, it effectively reduces the difficulty of operation and improves the efficiency of suction.

[0022] (3) This design features a filter ball at the front end of the saliva suction tube, with evenly distributed filter holes on its surface to improve the uniformity of suction around the oral cavity. The threaded drainage tube facilitates disassembly, replacement, or cleaning, and the internal filter screen protects the negative pressure components, enhancing the device's safety.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides an orthodontic puller with a protective sleeve, including two puller bodies 1 and a U-shaped fixing frame 2. The puller bodies 1 are fixed to both ends of the U-shaped fixing frame 2.

[0034] The hook body 1 has a slot 3 on one side that matches the shape of the corner of the mouth, and a silicone protective sleeve 4 is provided in the slot 3. The hook body 1 and the U-shaped fixing frame 2 have interconnected flow channels. The hook body 1 has an opening on the side away from the slot 3, and a saliva suction tube 5 is installed on the opening. The saliva suction tube 5 is connected to the flow channel, and the flow channel of the U-shaped fixing frame 2 is connected to the negative pressure component.

[0035] Working principle: A silicone protective sleeve 4 is installed in the slot of the hook body 1. The silicone protective sleeve 4 covers the part of the hook body 1 that contacts the corner of the lips, preventing the corner of the lips from contacting the hard hook body 1 and protecting the corner of the lips. The saliva suction tube inside the hook body 1 can draw saliva from the mouth and deliver it to the negative pressure component through the internal flow channel to realize the saliva suction function.

[0036] By placing a silicone protective sleeve 4 inside the groove 3 where the hook body 1 contacts the corner of the lip, contact between the corner of the lip and hard materials is avoided. Based on the elasticity and flexibility of the silicone protective sleeve 4, the corner of the lip is effectively protected. Compared to existing methods that rely on lubrication to moisten the corner of the lip, this structure is simpler and easier to operate. Furthermore, a flow channel is provided inside the hook body 1, which, together with a suction tube connecting to the flow channel on one side of the hook body 1, reduces the difficulty of oral examinations for doctors, improves overall efficiency and patient experience, and has strong practicality.

[0037] In a preferred embodiment, the silicone protective sleeve 4 has a crescent-shaped curved surface structure and is attached to the side wall of the slot 3. The two ends of the silicone protective sleeve 4 are provided with snap-fit ​​grooves 6 that cooperate with the two ends of the hook body 1. The snap-fit ​​grooves 6 are snapped into the two ends of the hook body 1.

[0038] Furthermore, the silicone protective cover 4 has evenly distributed heat dissipation holes.

[0039] The silicone protective sleeve 4 can be reliably engaged with the hook body 1 via the snap-fit ​​grooves 6 at both ends, allowing for flexible installation and removal and convenient use. Additionally, the ventilation holes on the silicone protective sleeve 4 maintain breathability during prolonged contact with the corner of the lip, reducing patient discomfort. Understandably, the silicone protective sleeve 4 can also be directly installed on the outside of the hook body 1; the fixing method is not limited, as long as it effectively isolates the hook body 1 from direct contact with the corner of the lip.

[0040] In this embodiment, the saliva suction tube 5 is a flexible tube. Using a flexible tube avoids damage when it comes into contact with areas such as the gums, thus improving safety during use.

[0041] In a preferred embodiment, there are multiple suction tubes 5, each evenly distributed on the hook body 1. Generally, four or six suction tubes can be provided on one hook body 1 for suctioning saliva from the outer side of the gums and the inside of the oral cavity. Specifically, the length of the suction tubes at both ends of the hook body 1 is shorter than the length of the suction tube in the middle section.

[0042] Furthermore, the saliva suction tube 5 is a bendable bamboo-joint tube.

[0043] The retractor body is equipped with suction tubes of various lengths and features a bendable, shape-adjustable bamboo-joint design, enabling suctioning of multiple locations within the oral cavity. This ensures the reliability of suctioning and effectively reduces the difficulty of operation and improves suctioning efficiency compared to suctioning performed by a doctor alone.

[0044] In a preferred embodiment, a filter ball 7 is provided at the end of the saliva suction tube 5 away from the hook body 1. The surface of the filter ball 7 is provided with multiple filter holes, and each filter hole is evenly distributed on the surface of the filter ball 7.

[0045] Furthermore, the U-shaped fixing frame 2 is provided with a drainage tube 8, one end of which is installed on the U-shaped fixing frame 2 and the other end is connected to the negative pressure component.

[0046] In this embodiment, one end of the drainage tube 8 is threadedly connected to the U-shaped fixing bracket 2, and a filter screen is provided inside the end near the U-shaped fixing bracket 2.

[0047] A filter ball is installed at the front end of the saliva suction tube, and evenly distributed filter holes are set on the surface of the filter ball to improve the uniformity of suction force around the mouth. The threaded drainage tube facilitates disassembly, replacement, or cleaning, and the internal filter screen also protects the negative pressure components, improving the safety of the device.

[0048] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
