Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a split-type 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.

[0004] Therefore, a new type of oral endoscope is needed to solve the above problems. However, existing oral endoscopes are one-piece structures, requiring cleaning and disinfection of the entire endoscope after use, which is inconvenient and time-consuming. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a convenient-to-clean split-type oral endoscope for maxillary sinus lift surgery.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A split-type oral endoscope for maxillary sinus lift surgery includes an endoscope body, which includes a handle and a head end that is inserted into the handle. The head end has an insertion section, and a camera module is provided at the front end of the insertion section. The handle has a first signal line connected to the endoscope host, and the head end has a second signal line connected to the camera module. When the head end is inserted into the handle, the first signal line and the second signal line are connected.

[0008] Because the endoscope body adopts a split structure, only the tip gets contaminated during use. Cleaning is simple; just detach the tip from the handle and clean only the tip. To facilitate connection between the tip and handle, a pin is provided at the tail end of the tip, and a corresponding socket is provided at the front end of the handle. Connecting the tip and handle is achieved by simply inserting the pin into the socket.

[0009] In the aforementioned split-type oral endoscope for maxillary sinus lift surgery, the anterior portion of the tip has a first bend, and the anterior portion of the first bend has a second bend. The insertion segment is located at the anterior end of the second bend. The midlines of the endoscope body, the first bend, the second bend, and the insertion segment are located in the same plane. Because the anterior portion of the tip has both a first and a second bend, the oral endoscope is shaped to conform to the oral cavity, facilitating the insertion of the insertion segment.

[0010] In the aforementioned split-type oral endoscope used for maxillary sinus lift surgery, the insertion segment and the second bending segment are coaxially arranged. The anterior end face of the second bending 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 excessive insertion and tissue damage.

[0011] In the aforementioned split-type oral endoscope used for maxillary sinus lift surgery, the front 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 front 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.

[0012] In the aforementioned split-type oral endoscope used for maxillary sinus lift surgery, the angle between the first and second bends is 90°-110°; the angle between the first bend and the endoscope body is 120°-160°.

[0013] In the aforementioned split-type oral endoscope for maxillary sinus lift surgery, the handle portion is provided with a first optical fiber extending to the endoscope host, and the head portion is provided with a second optical fiber extending to the front end face of the insertion section. When the head portion is inserted into the handle portion, the first optical fiber and the second optical fiber are connected.

[0014] In the aforementioned split-type oral endoscope used for maxillary sinus lift surgery, multiple second optical fibers are arranged around the camera module, and the number of first and second optical fibers is equal and arranged opposite to each other. This provides a wide illumination range and good illumination effect.

[0015] In the aforementioned split-type 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 optical fiber is located 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.

[0016] In the aforementioned split-type oral endoscope used for maxillary sinus lift surgery, the camera module is a camera. The camera is connected to the endoscope main unit via a signal cable, which provides power to the camera and simultaneously outputs the camera's signal to the endoscope main unit.

[0017] Compared with existing technologies, this split-type oral endoscope for maxillary sinus lift surgery has the following advantages: Because the endoscope body adopts a split structure, only the tip is contaminated during use. Cleaning is simple; the tip is detached from the handle and only the tip needs cleaning. Patient observation via endoscope avoids X-ray exposure, 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. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] like Figure 1 The illustrated split-type oral endoscope for maxillary sinus lift surgery includes an endoscope body 1, which comprises a handle portion 11 and a tip portion 12 that connects to the handle portion 11. To facilitate connection between the tip portion 12 and the handle portion 11, a pin is provided at the tail end of the tip portion 12, and a socket for the pin is provided at the front end of the handle portion 11. Connection between the tip portion 12 and the handle portion 11 is achieved simply by inserting the pin into the socket. Alignment marks can be provided between the handle portion 11 and the tip portion 12 to ensure their circumferential positioning.

[0023] like Figure 1 As shown, the front part of the head end 12 has a first bent section 14, the front part of the first bent section 14 has a second bent section 15, the front end of the second bent section 15 is provided with an insertion section 13, the front end of the insertion section 13 is provided with a camera module 2, the handle part 11 is provided with a first signal line 21 connected to the endoscope host, and the head end 12 is provided with a second signal line connected to the camera module 2. When the head end 12 is inserted into the handle part 11, the first signal line 21 is connected to the second signal line.

[0024] The midlines of the handle portion 11, the tip portion 12, the first bent section 14, the second bent section 15, and the insertion section 13 are located in the same plane. Because the tip portion 12 has the first bent section 14 and the second bent section 15 at its front, the oral endoscope is shaped to conform to the oral cavity, facilitating the insertion of the insertion section 13. Since the endoscope body 1 adopts a split structure, only the tip portion 12 is contaminated during use. For cleaning, simply detach the tip portion 12 from the handle portion 11 and clean only the tip portion 12, making cleaning convenient.

[0025] like Figure 1 As shown, the insertion segment 13 and the second bent segment 15 are coaxially arranged. The front end face of the second bent segment 15 is a limiting surface 16. The outer diameter of the limiting surface 16 is larger than the outer diameter of the insertion segment 13, and the insertion segment 13 is centrally located on the limiting surface 16. The limiting surface 16 can limit the insertion depth of the insertion segment 13, avoiding excessive insertion and damage to tissue.

[0026] like Figure 1 As shown, the front end of the second bending segment 15 has a blocking portion 17 whose outer diameter gradually increases from back to front, and a limiting surface 16 is located on the front end surface of the blocking portion 17. Without increasing the overall outer diameter of the second bending segment 15, the outer diameter of the limiting surface 16 is enlarged by setting the blocking portion 17, which saves material and reduces weight.

[0027] In this embodiment, the angle between the first bending segment 14 and the second bending segment 15 is 95°; the angle between the first bending segment 14 and the endoscope body 1 is 150°.

[0028] like Figure 1 As shown, the handle portion 11 is provided with a first optical fiber 31 extending to the endoscope host, such as... Figure 2 As shown, the head end 12 has a second optical fiber 32 extending to the front end face of the insertion section 13. When the head end 12 is inserted into the handle part 11, the first optical fiber 31 and the second optical fiber 32 are connected.

[0029] like Figure 2 As shown, there are multiple second optical fibers 32 arranged around the camera module 2, and the number of first optical fibers 31 is equal to the number of second optical fibers 32 and they are arranged opposite to each other.

[0030] In this embodiment, the insertion section 13 is provided with a first mounting hole and a second mounting hole. The camera module 2 is installed in the first mounting hole, and the optical fiber 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 section 13, with the camera module 2 and the lighting module located inside the partition.

[0031] In this embodiment, camera module 2 is a camera.

[0032] 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.
