Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology and relates to an oral endoscope, particularly an oral endoscope for maxillary sinus lift surgery. Background Technology
[0002] Maxillary sinus lift is an oral surgical procedure primarily used to address insufficient bone volume in the maxillary posterior teeth region to facilitate dental implantation. It involves using percussion or an ultrasonic bone cutter to remove bone from the maxillary sinus floor at the implant socket, elevating the sinus floor, implanting bone grafts, increasing the height of the alveolar bone, and thus increasing the length of the implant that can be placed.
[0003] Before implanting bone grafts, it is necessary to observe whether the maxillary sinus mucosa is damaged. The current routine procedure is to have the patient undergo an oral CT scan, and the doctor will judge whether the maxillary sinus mucosa is damaged by observing the CT images. This method has the following problems: 1. CT scans use X-rays, which pose a certain radiation risk; 2. The patient needs to be moved from the operating room to the CT equipment room, which is far apart, wasting time and prolonging the patient's suffering. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an oral endoscope for maxillary sinus lift surgery that allows for rapid observation.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] An oral endoscope for maxillary sinus lift surgery includes an endoscope body and an insertion section located at the front end of the endoscope body. The front end of the insertion section is provided with a camera module and an illumination module. The illumination module is connected to the endoscope host via a signal line passing through the endoscope body and is also connected to the endoscope host. The front part of the endoscope body has a first bend, and the front part of the first bend has a second bend. The insertion section is located at the front end of the second bend. The midlines of the endoscope body, the first bend, the second bend, and the insertion section are located in the same plane.
[0007] When using the endoscope, hold the main body and insert the tip into the oral cavity. Then, insert the insertion section into the foramen of the alveolar bone. Observe whether the maxillary sinus mucosa is damaged through the camera module. During this process, the illumination module provides illumination for the camera module's observation. Because the endoscope has a first bend and a second bend at the front, the oral endoscope is made into a shape that conforms to the shape of the oral cavity, facilitating the insertion of the insertion section.
[0008] In the oral endoscope used for the above-mentioned maxillary sinus lift procedure, the insertion segment and the second bend segment are coaxially arranged. The anterior end face of the second bend segment serves as a limiting surface, and the outer diameter of the limiting surface is larger than the outer diameter of the insertion segment. The insertion segment is centrally positioned on the limiting surface. The limiting surface restricts the insertion depth of the insertion segment, preventing tissue damage due to excessive insertion.
[0009] In the oral endoscope used for the aforementioned maxillary sinus lift, the anterior end of the second bend has a blocking portion whose outer diameter gradually increases from back to front, and the limiting surface is located on the anterior end face of the blocking portion. Without increasing the overall outer diameter of the second bend, the outer diameter of the limiting surface is enlarged by setting up the blocking portion, thus saving material and reducing weight.
[0010] In the oral endoscope used for the above-mentioned maxillary sinus lift surgery, the angle between the first bend and the second bend is 90°-110°; the angle between the first bend and the endoscope body is 120°-160°.
[0011] In the aforementioned oral endoscope for maxillary sinus lift surgery, the insertion segment is provided with a first mounting hole and a second mounting hole. The camera module is installed in the first mounting hole, and the illumination module is installed in the second mounting hole. To achieve a seal, a transparent partition, such as a glass plate, can be installed at the front end of the insertion segment, with the camera module and illumination module located inside the partition.
[0012] In the oral endoscope used for the aforementioned maxillary sinus lift surgery, the camera module is a camera. The camera is connected to the endoscope host via a signal cable, which provides power to the camera and simultaneously outputs the camera's signal to the endoscope host.
[0013] In the oral endoscope used for the above-mentioned maxillary sinus lift surgery, the illumination module is an optical fiber. The front end of the optical fiber extends to the front end of the insertion section, and the rear end of the optical fiber extends to the endoscope host. A light source is provided in the endoscope host, and the light emitted by the light source is transmitted to the front end of the insertion section through the optical fiber to provide illumination for the camera module.
[0014] In the oral endoscope used for the aforementioned maxillary sinus lift surgery, multiple illumination modules are arranged around the camera module. This provides a wide illumination range and excellent illumination effect.
[0015] Compared with existing technologies, this maxillary sinus lift procedure using an oral endoscope has the following advantages: patients are observed using an endoscope without being exposed to X-rays, eliminating radiation risks and ensuring high safety; the endoscope conforms to the oral cavity shape, has a reasonable structural design, is easy to use, and provides good observation results; patients do not need to move during the procedure, saving time.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1 The oral endoscope used for maxillary sinus lift surgery shown includes an endoscope body 1 and an insertion section 2 located at the front end of the endoscope body 1. The insertion section 2 is cylindrical and its front end is equipped with a camera module 3 and an illumination module 4. In this embodiment, the camera module 3 is a camera, and the illumination module 4 is an optical fiber. To obtain the best illumination effect, such as... Figure 2 As shown, the light is set to multiple and surrounds the camera setup.
[0021] To facilitate the installation of the camera and optical fiber, a first mounting hole and a second mounting hole are provided in the insertion section 2. The camera is installed in the first mounting hole, and the number of the second mounting holes is equal to the number of optical fibers. The optical fibers are installed in the corresponding second mounting holes.
[0022] To achieve a seal, a transparent partition, such as a glass plate, can be installed at the front end of the insertion section 2, with the camera module 3 and the lighting module 4 located inside the partition.
[0023] like Figure 1 As shown, the camera is connected to the endoscope host via a signal line 5 that runs through the endoscope body 1. The rear end of the optical fiber extends to the endoscope host. A light source is provided inside the endoscope host, and the light emitted by the light source is transmitted to the front end of the insertion section 2 via the optical fiber.
[0024] like Figure 1 As shown, the endoscope body 1 has a first bend section 11 at the front, and a second bend section 12 at the front of the first bend section 11. The insertion section 2 is located at the front end of the second bend section 12. The midlines of the endoscope body 1, the first bend section 11, the second bend section 12 and the insertion section 2 are located in the same plane.
[0025] like Figure 1As shown, the insertion segment 2 and the second bent segment 12 are coaxially arranged. The front end face of the second bent segment 12 is a limiting surface 13. The outer diameter of the limiting surface 13 is larger than the outer diameter of the insertion segment 2, and the insertion segment 2 is centrally positioned on the limiting surface 13. The limiting surface 13 can limit the insertion depth of the insertion segment 2 to avoid damaging the tissue.
[0026] like Figure 1 As shown, the front end of the second bending segment 12 has a blocking portion 14 whose outer diameter gradually increases from back to front, and a limiting surface 13 is located on the front end face of the blocking portion 14. Without increasing the overall outer diameter of the second bending segment 12, the outer diameter of the limiting surface 13 is enlarged by setting the blocking portion 14, which saves material and reduces weight.
[0027] The included angle between the first bending segment 11 and the second bending segment 12 is 90°-110°, and is 95° in this embodiment; the included angle between the first bending segment 11 and the endoscope body 1 is 120°-160°, and is 150° in this embodiment.
[0028] During use, hold the endoscope body 1 and insert its tip into the oral cavity. Then, insert the insertion segment 2 into the foramen of the alveolar bone. Observe whether the maxillary sinus mucosa is damaged through the camera module 3. During this process, the illumination module 4 provides illumination for the observation of the camera module 3. Because the endoscope body 1 has a first bent segment 11 and a second bent segment 12 at the front, the oral endoscope is made into a shape that conforms to the shape of the oral cavity, which facilitates the insertion segment 2.
[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
