Description

Technical Field

[0001] This invention relates to the field of oral medical devices, specifically to an inflatable oral examination device. Background Technology

[0002] Oral biopsy involves a delicate surgical procedure to extract a small tissue sample from a suspected lesion in the oral cavity. After pathological processing, the sample is observed under a microscope to examine cell morphology, arrangement, and changes in tissue structure, thereby clarifying the nature, pathological type, and degree of malignancy of the lesion. This process can not only accurately distinguish between infection, autoimmune diseases, and tumors, avoiding misdiagnosis and mistreatment, but also provide crucial information for surgical planning, treatment selection (such as sensitivity to radiotherapy and chemotherapy), and prognostic assessment by evaluating the depth of tumor invasion, whether it has invaded surrounding tissues (such as bone and nerves), and the extent of vascular and nerve infiltration.

[0003] Existing oral examination devices typically require patients to voluntarily open their mouths for sampling and testing, or they use traction devices to open the patient's mouth. This can easily lead to insufficient mouth opening, making it difficult to observe the floor of the mouth and the base of the tongue, or the traction devices can cause traction injuries to the corners of the mouth, thus causing inconvenience in oral examinations. Summary of the Invention

[0004] The purpose of this invention is to provide an inflatable oral cavity examination device to solve the problem of inconvenience in oral cavity examination in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an inflatable oral cavity testing device, comprising a main frame and a robotic arm, used for testing a patient's oral cavity, further comprising: a main body mechanism, disposed on the main frame, used to assist the patient's mouth in opening, the main body mechanism comprising two corrugated airbags fixedly disposed on the main frame, and two receiving frames fixedly disposed on the side wall of the main frame; a clamping mechanism, disposed on the robotic arm, used for clamping oral cavity testing instruments, the clamping mechanism comprising a torsion spring shaft fixedly disposed at the end of the robotic arm, the robotic arm being elastically rotatably disposed with two fixed clamps via the torsion spring shaft; and a traction mechanism, disposed on the robotic arm and the fixed clamps, used for traction of the fixed clamps for clamping, the traction mechanism comprising a pull rod slidably disposed on the robotic arm, and traction ropes fixedly disposed on the inner walls of both fixed clamps, the other ends of the traction ropes being respectively fixedly disposed on the inner wall of the pull rod.

[0006] Furthermore, the main body mechanism also includes a valve stem fixedly disposed on the side wall of the main body frame, and the inner wall of the receiving frame is fixedly provided with a meshing groove.

[0007] Furthermore, the main structure also includes elastic ropes symmetrically fixed on both sides of the side wall of the main frame, and a detection port is provided between the two main frames.

[0008] Furthermore, the clamping mechanism also includes clamping holes formed on the two fixed clamps.

[0009] Furthermore, the clamping mechanism also includes a grip fixedly mounted on the robotic arm.

[0010] Furthermore, the traction mechanism also includes connecting holes respectively opened in the inner walls of the two fixed clamps, and the two traction ropes pass through the two connecting holes and into the interior of the two fixed clamps respectively.

[0011] Furthermore, the traction mechanism also includes a fixed shaft fixedly disposed inside the robotic arm, and a restoring spring fixedly disposed at the end of the fixed shaft; a sliding shaft is slidably disposed inside the robotic arm, and the fixed shaft and the sliding shaft are elastically disposed through the restoring spring.

[0012] Furthermore, the robotic arm has two circular channels inside, through which the two traction ropes are slidably disposed inside the robotic arm.

[0013] Compared with existing technologies, the present invention provides an inflatable oral examination device. By placing two main frames on the outside of the patient's mouth, the upper and lower teeth are respectively engaged in the occlusal grooves of the two supporting frames, and secured to the ear with elastic ropes to enhance stability. Then, air is inflated into two interconnected corrugated air bladders through valves, causing them to expand and push the two main frames to move in opposite directions. This gently and controllably opens the patient's mouth, forming an examination opening for observation or operation. During the examination, medical personnel can hold the handle on the robotic arm and pull the lever backward, causing the traction rope to pull the two fixed clamps to rotate and close around the torsion spring shaft, thereby clamping the patient's oral cavity. The detection or sampling instrument, placed in the clamping hole, is inserted into the oral cavity through the detection port for examination or biopsy. After the operation, the pull rod is released, and the fixed clamp automatically resets and unfolds under the action of the torsion spring shaft. The advantages of this device are: the inflation and expansion of the corrugated airbag achieves non-invasive and uniform opening of the oral cavity, avoiding the mouth corner strain that may be caused by traditional mechanical traction; the detection port provides a full field of vision and operating channel, which is conducive to observation and sampling of deep areas such as the floor of the mouth and the base of the tongue; the design of the robotic arm and clamping mechanism makes the instrument clamping stable and the operation flexible, solving the problems of inconvenient operation and easy shaking of handheld instruments, and improving the safety and convenience of oral examination as a whole.

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] Example 1:

[0026] This invention provides an inflatable oral cavity testing device, including a main frame 1 and a robotic arm 5, for testing a patient's oral cavity. It further includes: a main structure, mounted on the main frame 1, for assisting the patient's mouth in opening; the main structure includes two corrugated airbags 3 fixedly mounted on the main frame 1, and two receiving frames 7 fixedly mounted on the side wall of the main frame 1; a clamping mechanism, mounted on the robotic arm 5, for clamping oral cavity testing instruments; the clamping mechanism includes a torsion spring shaft 12 fixedly mounted at the end of the robotic arm 5, and two fixed clamps 11 elastically rotated on the robotic arm 5 via the torsion spring shaft 12; and a traction mechanism, mounted on the robotic arm 5 and the fixed clamps 11, for traction of the fixed clamps 11 for clamping; the traction mechanism includes a pull rod 10 slidably mounted on the robotic arm 5, and traction ropes 15 fixedly mounted on the inner walls of both fixed clamps 11, with the other ends of the traction ropes 15 respectively fixedly mounted on the inner walls of the pull rod 10.

[0027] Simultaneously, the two main frames 1 are placed on the outside of the patient's mouth, so that the upper and lower teeth bite into the occlusal grooves 8 of the two receiving frames 7 respectively, and are fixed to the ears by elastic ropes 2 to enhance stability. Then, air is inflated into the two interconnected corrugated air bladders 3 through the valve 6, causing them to expand and push the two main frames 1 to move in opposite directions, thereby gently and controllably opening the patient's mouth to form an examination port 4 for observation or operation. During the examination, medical staff can hold the handle 9 on the robotic arm 5 and pull the lever 10 backward, causing the traction rope 15 to pull the two fixed clamps 11 to rotate and close around the torsion spring shaft 12, thereby clamping the examination device placed in the clamping hole 13. The testing or sampling instrument is inserted into the oral cavity through the detection port 4 to perform examination or biopsy. After the operation, the pull rod 10 is released, and the fixing clamp 11 automatically resets and unfolds under the action of the torsion spring shaft 12. The advantages of this device are: the inflation and expansion of the corrugated airbag 3 achieves non-invasive and uniform opening of the oral cavity, avoiding the mouth corner injury that may be caused by traditional mechanical traction; the detection port 4 provides a full field of vision and operating channel, which is conducive to observation and sampling of deep areas such as the floor of the mouth and the root of the tongue; the design of the robotic arm 5 and the clamping mechanism makes the instrument clamping stable and the operation flexible, solving the problems of inconvenient operation and easy shaking of handheld instruments, and improving the safety and convenience of oral examination as a whole.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The main structure includes a main frame 1, a corrugated airbag 3, a detection port 4, a receiving frame 7, and a meshing groove 8;

[0029] By setting two main frames 1 and fixing two corrugated airbags 3 between the two main frames 1, the two main frames 1 can be movably connected by the two corrugated airbags 3 and used for elastic support. A detection port 4 is opened between the two main frames 1, so that when the two main frames 1 and the corrugated airbags 3 are in use, the two main frames 1 can be limited to the patient's mouth, and oral detection operations can be performed in the patient's oral cavity through the detection port 4.

[0030] Meanwhile, a support frame 7 is fixedly connected to the inner wall of each of the two main frames 1, and an occlusal groove 8 is provided on the side wall of the support frame 7. This allows the patient's upper and lower teeth to bite onto the two support frames 7 during use, and the patient's teeth and lips to be positioned within the occlusal groove 8. This facilitates the positioning of the patient's teeth and lips on the main frame 1. A silicone pad is fixedly connected to the inner wall of the occlusal groove 8 to improve the patient's comfort when biting onto the support frame 7. Thus, during use, the two main frames 1 can be positioned and bitten into the patient's mouth by the two support frames 7 and the occlusal groove 8.

[0031] Secondly, valves 6 are fixedly connected to the side walls of the main frame 1, so that the two main frames 1 and the corrugated airbags 3 can first be engaged with the patient's mouth through the two support frames 7 and the occlusal groove 8 during use. Then, the valves 6 are connected to the inflation device, which inflates the two corrugated airbags 3 through the valves 6. The two corrugated airbags 3 are connected by a structure, so that the two corrugated airbags 3 can be gradually inflated from the folded state to push the two main frames 1 to slide relative to each other. Then, the two support frames 7 and the occlusal groove 8 can open the patient's mouth, so that medical staff can easily check the angle of the patient's oral cavity. Then, the patient's oral cavity can be checked through the detection port 4, so as to facilitate the detection of the floor of the mouth and the root of the tongue, and avoid traction damage to the corners of the patient's mouth.

[0032] In addition, elastic ropes 2 are fixedly connected to both sides of the side walls of the two main frames 1, so that when the two main frames 1 and the corrugated airbag 3 are used, the two elastic ropes 2 can be respectively locked onto the patient's two ears, thereby preventing the main frames 1 from shifting excessively during use and improving the stability of the main frames 1.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 4 and Figure 5 The clamping mechanism includes a robotic arm 5, a torsion spring shaft 12, a fixed clamp 11, a clamping hole 13, and a handle 9;

[0035] By incorporating a robotic arm 5, medical staff can use the robotic arm 5 to hold the camera or sampling equipment when conducting tests and sampling in the patient's oral cavity. The equipment can then be inserted into the patient's oral cavity through the testing port 4 to conduct tests or sampling, thus replacing the practice of medical staff holding medical instruments to conduct tests or sampling in the patient's oral cavity. This avoids the problem of medical staff having large hands, which makes it difficult to hold medical instruments to conduct tests or sampling in the patient's oral cavity.

[0036] Meanwhile, a torsion spring shaft 12 is fixedly connected to the end of the robotic arm 5, and two fixed clamps 11 are rotatably connected to the torsion spring shaft 12. This allows the robotic arm 5 to be elastically rotatably connected to the two fixed clamps 11 via the torsion spring shaft 12. The two fixed clamps 11 are designed to be elastically supported and unfolded by the torsion spring shaft 12 when not subjected to external force. This allows the two fixed clamps 11 to be in an unfolded state during use, making it easy to place medical instruments between the two fixed clamps 11. By applying tension to the two fixed clamps 11, the two fixed clamps 11 can stably clamp the medical instruments. At the same time, each of the two fixed clamps 11 has a clamping hole 13, so that when the two fixed clamps 11 are subjected to tension for clamping, the two clamping holes 13 can clamp the cylindrical medical instruments, thereby improving the clamping practicality of the fixed clamps 11.

[0037] Secondly, a handle 9 is fixedly connected to the other end of the robotic arm 5, so that medical staff can hold the handle 9 when using the robotic arm 5, so as to make it easier to hold and use the robotic arm 5, thereby improving the ease of use of the robotic arm 5.

[0038] Example 3:

[0039] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The traction mechanism includes a fixed shaft 17, a restoring spring 16, a sliding shaft 18, a pull rod 10, a traction rope 15, and a connecting hole 14;

[0040] By fixing a fixed shaft 17 inside the robotic arm 5 and sliding a sliding shaft 18 inside the robotic arm 5, and fixing a restoring spring 16 between the fixed shaft 17 and the sliding shaft 18, the sliding shaft 18 can be elastically slidably connected to the inside of the robotic arm 5 through the restoring spring 16. A pull rod 10 is fixedly connected to the end of the sliding shaft 18, so that the pull rod 10 can be elastically slidably connected to one end of the robotic arm 5 through the sliding shaft 18.

[0041] Meanwhile, two traction ropes 15 are fixedly connected inside the two fixed clamps 11 respectively, and each of the two fixed clamps 11 has a connecting hole 14. The two traction ropes 15 on the two fixed clamps 11 pass through the connecting holes 14 and cross each other inside the two fixed clamps 11. Two circular channels are opened inside the robotic arm 5, so that the two traction ropes 15 pass through the two circular channels and pass through the two circular channels to enter the interior of the robotic arm 5 and are then fixedly connected to the inner wall of the pull rod 10. Thus, when the pull rod 10 is elastically pulled, it can be supported by the two traction ropes. The two fixed clamps 11 are rotated by the pull rod 10. Therefore, when the two fixed clamps 11 are in use, they are initially supported by the torsion spring shaft 12 and are in an unfolded state. When the pull rod 10 is pulled, the two traction ropes 15 can pull the two fixed clamps 11 to rotate and merge, thereby achieving the purpose of clamping the medical instruments on the two fixed clamps 11 for use. Therefore, the robotic arm 5 can clamp the medical instruments and replace medical staff in holding the medical instruments and inserting them into the patient's mouth for testing or sampling, thereby improving the convenience of testing and sampling in the patient's mouth.

[0042] Working principle: Before operation, medical staff first place the two main frames 1 of the device on the corresponding positions of the upper and lower jaws on the outside of the patient's mouth, guiding the patient to bite and fix the upper and lower teeth into the occlusal grooves 8 of the two receiving frames 7, so that the lips and teeth are securely accommodated in the grooves. Then, the elastic ropes 2 connected to both sides of the main frame 1 are hung on the patient's ears to initially fix the device and prevent it from shifting. After the preparation is complete, the external inflation device is connected through the valve 6 on the side wall of the main frame 1, and the two interconnected corrugated air bladders 3 are slowly inflated. As the gas is injected, the corrugated air bladders 3, which were originally in a folded state, gradually expand evenly, generating a lateral expansion force, thereby gently and controllably pushing the two main frames 1 to move towards each other, and then through the receiving frames 7 and the occlusal grooves 8. The slot 8 drives the patient's upper and lower jaws to open synchronously until a suitable opening for examination is achieved. During this process, the inflated corrugated airbag 3 forms a stable elastic support between the two main frames 1, which avoids excessive traction of the corners of the mouth or soft tissue damage that may be caused by traditional mechanical traction, and also naturally forms an open detection port 4 between the two main frames 1, providing a clear and wide passage for subsequent instrument entry. After the oral cavity is fully opened, the medical staff holds the handle 9 at the end of the robotic arm 5 and moves the front end of the robotic arm 5 to the vicinity of the detection port 4. At this time, the two fixing clamps 11 are in a naturally open state under the elastic action of the torsion spring shaft 12, which facilitates the placement of endoscopes, biopsy forceps and other detection or sampling instruments between the two fixing clamps 11. Then, the operator moves backward. Pulling the lever 10, which is slidably mounted on the robotic arm 5, compresses the recovery spring 16 through the internally connected sliding shaft 18, and simultaneously pulls two traction ropes 15, which are respectively fixed to the inner walls of two clamps 11. The two traction ropes 15 pass through the connecting hole 14 on the clamp 11 and the circular channel inside the robotic arm 5. Under the action of the pulling force, the two clamps 11 drive the two clamps 11 to overcome the torque of the torsion spring shaft 12, rotate around the shaft and gradually close, thereby firmly clamping and fixing the instrument rod through the clamping hole 13. After the instrument is firmly clamped, the operator can smoothly insert the robotic arm 5 and the front instrument into the patient's oral cavity through the detection port 4, and use the flexible guidance of the robotic arm 5 to observe or take tissue samples from areas that are difficult to see directly, such as the base of the tongue, floor of the mouth, and cheek. During operation, the clamping force can be finely adjusted by adjusting the pulling amplitude of the lever 10, and the position can also be precisely adjusted with the help of the robotic arm 5. After the test or sampling is completed, the instrument is first removed from the oral cavity, and then the lever 10 is released. At this time, the restoring spring 16 pushes the sliding shaft 18 and the lever 10 to reset, the traction rope 15 is relaxed, and the two fixed clamps 11 automatically open under the elastic restoring force of the torsion spring shaft 12, releasing the instrument. Finally, the gas in the corrugated airbag 3 is released through the valve 6, causing it to contract and return to its original position. The patient's teeth are disengaged from the occlusal groove 8, and the entire device can be gently removed from the oral cavity, completing the entire testing process. The entire process integrates oral cavity opening, instrument clamping and operation, and has the advantages of safety, stability and ease of operation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
