Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral medical device technology, specifically to an integrated saliva suction periosteum separator. Background Technology
[0002] A periosteal separator is a medical device used in orthopedic surgery. Its main functions include separating the periosteum from the soft tissue attached to the bone during oral surgery, assisting in minimally invasive tooth extractions to reduce trauma to the alveolar bone. Perioosteal separators are mostly made of stainless steel to ensure durability and corrosion resistance. The structure consists of a handle and a head (or working end). The handle is designed for easy gripping by the surgeon, and the working end is flat or slightly curved to adapt to the physiological structure of the periosteum. In tooth extraction surgery, the periosteal separator is often used in conjunction with other tools (such as dental elevators and extraction forceps) to ensure surgical precision and safety.
[0003] In current tooth extraction surgeries, patients experience bleeding and saliva in their mouths. To maintain a clear surgical field, ensure the smooth progress of the surgery, and reduce patient discomfort, a saliva suction tube is connected to the suction system of the dental treatment machine. The negative pressure of the suction system removes saliva, blood, and other fluids from the mouth. However, the inventors of this application, through clinical experience, have found that currently, in tooth extraction surgeries, the periosteal separator is typically held by the dentist, while the saliva suction tube is typically held by the nurse. The use of the saliva suction tube requires close coordination with the dentist's operation to ensure a smooth procedure. However, due to the limited operating space at the extraction site, the nurse's field of vision is largely obstructed by the dentist's movements, making close coordination difficult. Therefore, there is an urgent need to improve this situation. Utility Model Content
[0004] To address the technical problem that existing periosteal separators and suction tubes are operated separately by doctors and nurses, but due to the limited operating space at the tooth extraction site, the nurse's operating field of vision is basically blocked by the doctor's operation, making it difficult to form a close coordination with the doctor's operation, this utility model provides an integrated suction periosteal separator.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] An integrated saliva suction periosteum separator includes a handle. One end of the handle is integrally formed with a flat working end. The axial direction of the flat working end and the axial direction of the handle form a predetermined angle. The outer end face of the flat working end away from the handle in the axial direction is provided with a liquid inlet slit. The other end of the handle is provided with a liquid outlet. A saliva suction channel is provided through the flat working end and the handle. The two ends of the saliva suction channel are respectively connected to the liquid inlet slit and the liquid outlet.
[0007] Compared with the prior art, the integrated saliva suction periosteal separator provided by this utility model has a liquid inlet slit on the outer end face of the first flat working end away from the handle in the axial direction, and a liquid outlet at the other end of the handle. A saliva suction channel connected to the liquid inlet slit and the liquid outlet is arranged through the first flat working end and the handle. Before operation, one end of the existing saliva suction tube can be connected to the liquid outlet, and the other end can be connected to the saliva suction system of the oral comprehensive treatment machine. When the doctor holds the saliva suction periosteal separator for operation, the negative pressure suction of the saliva suction system can simultaneously suction away the bleeding, saliva and other liquids generated in the patient's mouth in sequence through the liquid inlet slit, saliva suction channel, liquid outlet and saliva suction tube. At this time, only one doctor needs to complete the periosteal separation and saliva suction operation. The doctor's surgical field of vision is completely undisturbed, ensuring the smooth progress of the operation.
[0008] Furthermore, the outer end face of the flat working end on the side away from the handle in the axial direction is a wavy surface.
[0009] Furthermore, the central surface of the handle is a smooth cylindrical surface, and the handle surfaces on both sides of the smooth cylindrical surface are provided with multiple recesses.
[0010] Furthermore, the liquid outlet is a stepped anti-slip outlet. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0015] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "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 this utility model and simplifying the description, and 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. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] Please refer to Figure 1 and Figure 2 As shown, this utility model provides an integrated saliva suction membrane separator, including a handle 1. One end of the handle 1 is integrally formed with a flat working end 2. The axial direction of the flat working end 2 forms a predetermined angle with the axial direction of the handle 1, that is, the central axis of the flat working end 2 and the central axis of the handle 1 are not on the same straight line. The outer end face of the flat working end 2 away from the handle 1 in the axial direction is provided with a liquid inlet slit 21. The other end of the handle 1 is provided with a liquid outlet 11. A saliva suction channel (not shown in the figure) is provided through the flat working end 2 and the handle 1. The two ends of the saliva suction channel are respectively connected to the liquid inlet slit 21 and the liquid outlet 11, that is, the liquid inlet slit 21, the saliva suction channel and the liquid outlet 11 are connected in sequence.
[0018] Compared with the prior art, the integrated saliva suction periosteal separator provided by this utility model has a liquid inlet slit on the outer end face of the first flat working end away from the handle in the axial direction, and a liquid outlet at the other end of the handle. A saliva suction channel connected to the liquid inlet slit and the liquid outlet is arranged through the first flat working end and the handle. Before operation, one end of the existing saliva suction tube can be connected to the liquid outlet, and the other end can be connected to the saliva suction system of the oral comprehensive treatment machine. When the doctor holds the saliva suction periosteal separator for operation, the negative pressure suction of the saliva suction system can simultaneously suction away the bleeding, saliva and other liquids generated in the patient's mouth in sequence through the liquid inlet slit, saliva suction channel, liquid outlet and saliva suction tube. At this time, only one doctor needs to complete the periosteal separation and saliva suction operation. The doctor's surgical field of vision is completely undisturbed, ensuring the smooth progress of the operation.
[0019] For a specific embodiment, please refer to Figure 1 and Figure 2 As shown, the outer end face of the flat working end 2 on the side away from the handle 1 is a wavy surface. Therefore, when the doctor holds the saliva suction periosteal separator to operate, it can avoid the outer end face of the flat working end 2 on the side away from the handle 1 from being in complete close contact with the soft tissue, which would prevent the bleeding, saliva and other liquids generated in the patient's mouth from being suctioned away in time.
[0020] For a specific embodiment, please refer to Figure 1 As shown, the middle surface of the handle 1 is a smooth cylindrical surface, and the handle 1 surface on both sides of the smooth cylindrical surface is provided with multiple recesses 12, so that the doctor's fingers can quickly slide through the smooth cylindrical surface in the middle to the other end and perform gripping operations by the blocking friction formed by the recesses 12.
[0021] For a specific embodiment, please refer to Figure 1 As shown, the liquid outlet 11 is a stepped anti-slip outlet. Therefore, when one end of the existing saliva tube is connected to the stepped anti-slip outlet, the saliva tube can be effectively prevented from slipping off the liquid outlet 11, thereby enhancing the reliability of the connection.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
