Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a splash-proof lip and cheek retractor. Background Technology

[0002] In oral surgery, labial and buccal retractors are often used to retract and fix the soft tissues of the patient's lips and cheeks. Labial and buccal retractors can also isolate and protect the labial and buccal mucosa and tongue from abrasion caused by the upward angle of the handpiece.

[0003] Because the surface of the labial and buccal retractors is smooth, the airflow angle changes the direction of the water when the handpiece is sprayed at an upward angle, causing the water to flow back towards the side of the medical staff. This increases the risk of occupational exposure for medical staff and can also splash onto their face shields, causing blurred vision and affecting medical procedures and surgical processes. Utility Model Content

[0004] This application provides a splash-proof lip and cheek hook, which solves the problem in the prior art where, when using a tilted handpiece to dispense water, the airflow angle changes the direction of the water, causing it to flow back towards the healthcare worker, thus increasing the risk of occupational exposure. This invention effectively reduces water splashing towards the handle, thereby lowering the risk of occupational exposure and preventing water contamination of the face shield, which could affect healthcare operations.

[0005] This utility model provides a splash-proof lip and cheek hook, including a hook body, a baffle plate, and two baffle strips; the two baffle strips are arranged opposite to each other, and both baffle strips are connected to one side of the hook body; the two baffle strips and the hook body form a flow channel; the baffle plate is connected to the side of the hook body near the baffle strips, and the baffle plate is disposed between the two baffle strips, and the baffle plate divides the flow channel into a first branch and a second branch.

[0006] In one possible viewing configuration, the hook body includes a locking part, a gripping part, and a cheek-fitting part; the two ends of the gripping part are respectively connected to the locking part and the cheek-fitting part; two opposing deflector strips are connected to one side of the gripping part and the cheek-fitting part; the deflector plate is connected to the side of the cheek-fitting part near the deflector strips.

[0007] In one possible view configuration, the deflector is U-shaped.

[0008] In one possible viewing configuration, the opening of the deflector faces the grip.

[0009] In one possible viewing configuration, the angle between the grip portion and the cheek contact portion is 150°.

[0010] In one possible viewing configuration, the hook body is made of stainless steel.

[0011] In one possible view configuration, the deflector is made of stainless steel.

[0012] In one possible view configuration, the connection between the two deflectors and the hook body is provided with rounded corners.

[0013] One or more technical solutions provided in this application have at least the following technical effects:

[0014] This utility model embodiment employs a splash-proof lip and cheek hook, including a hook body, a baffle plate, and two baffle strips. The two baffle strips are arranged opposite each other and are each connected to one side of the hook body. The two baffle strips and the hook body form a flow channel. The baffle plate is connected to the side of the hook body near the baffle strips and is positioned between the two baffle strips, dividing the flow channel into a first branch and a second branch. When water is sprayed from an upward-angled handpiece for dental separation, a low-pressure zone is created at the baffle plate due to its shape and the inertia of the water column. The water column bypasses the baffle plate and enters the first and second branches. The narrower channels of the first and second branches increase the flow velocity and reduce the water pressure. The separation of the water column causes vortices to form at the edge of the baffle plate, thereby reducing splashing towards the handle. This application solves the problem in the prior art where, when using a lip and cheek hook with an upward-angled handpiece for dental separation, the airflow angle changes the direction of the water, causing the water to flow back towards the medical staff, thus increasing the risk of occupational exposure for medical staff. This invention achieves the technical effect of reducing water splashing towards the handle. It also reduces the risk of occupational exposure for healthcare workers and prevents water contamination of face shields from affecting healthcare operations. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] In the description of the embodiments of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the embodiments of this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0021] This utility model embodiment provides a splash-proof lip and cheek hook, such as Figure 1-2 As shown, it includes a hook body 1, a baffle plate 2, and two baffle strips 3; the two baffle strips 3 are arranged opposite each other, and both baffle strips 3 are connected to one side of the hook body 1; the two baffle strips 3 and the hook body 1 form a flow channel 4; the baffle plate 2 is connected to the side of the hook body 1 near the baffle strips 3, and the baffle plate 2 is arranged between the two baffle strips 3, and the baffle plate 2 divides the flow channel 4 into a first branch 5 and a second branch 6.

[0022] For example, when the phone sprays water at an upward angle, the water flow is blocked by the baffle 2, creating a split: part of the water flows along the first branch 5 on the outer side of the baffle 2, and the other part flows along the second branch 6 on the inner side. Since the channel width of the first branch 5 and the second branch 6 is only 1 / 3 or 1 / 2 of the original flow channel 4, the specific width range can be designed according to actual needs. According to Bernoulli's principle, the water flow velocity increases and the pressure decreases, thereby reducing the kinetic energy of the water flow towards the handle. At the same time, the edge of the baffle 2 forms a vortex zone due to water flow separation, further adsorbing and dispersing residual water droplets, achieving the technical effect of reducing splash volume.

[0023] In the embodiments of this application, such as Figure 1-2 As shown, the hook body 1 includes a locking part 11, a gripping part 12, and a cheek-fitting part 13; the two ends of the gripping part 12 are respectively connected to the locking part 11 and the cheek-fitting part 13; two opposing deflector strips 3 are connected to one side of the gripping part 12 and the cheek-fitting part 13; the deflector plate 2 is connected to the side of the cheek-fitting part 13 near the deflector strips 3.

[0024] For example, the locking part 11 adopts a buckle structure with anti-slip texture, which can be adapted to the fixing slots of dental treatment tables of different sizes; the grip part 12 has a textured surface with concave and convex anti-slip texture, and the length is designed to be 80-100mm, which meets the ergonomic grip requirements; the cheek contact part 13 is an arc-shaped curved surface with a radius of curvature R=25-35mm, which matches the anatomical shape of the patient's face and reduces local pressure.

[0025] In the embodiments of this application, such as Figure 1-2 As shown, the baffle 2 is U-shaped.

[0026] For example, the U-shaped baffle 2 has an opening width of 7 mm and a depth of 3 mm, and its recessed structure can guide most of the water flow along a predetermined path.

[0027] In the embodiments of this application, such as Figure 1-2 As shown, the opening of the deflector 2 faces the grip portion 12.

[0028] For example, the opening of the baffle 2 facing the grip 12 enables the diverted water flow to be discharged mainly away from the medical staff.

[0029] In the embodiments of this application, such as Figure 1-2 As shown, the angle between the gripping part 12 and the cheek-fitting part 13 is 150°;

[0030] For example, a 150° angle can distribute stress evenly at the connection between the grip 12 and the cheek contact part 13, avoiding local stress concentration that could cause instrument deformation, while maximizing the exposed area of ​​the surgical field.

[0031] In the embodiments of this application, such as Figure 1-2 As shown, the hook body 1 is made of stainless steel;

[0032] In the embodiments of this application, such as Figure 1-2 As shown, the baffle 2 is made of stainless steel;

[0033] For example, the baffle 2 and the hook body 1 are integrally formed by laser welding.

[0034] In the embodiments of this application, such as Figure 1-2 As shown, the connection between the two baffles 3 and the hook body 1 is provided with rounded corners.

[0035] For example, the fillet radius R = 1.5-2.0 mm.

[0036] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0037] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
