Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a mandibular continuous lifting device for digestive endoscopic diagnosis and treatment. Background Art

[0002] During the process of digestive endoscopy diagnosis and treatment, lifting the jaw is an important operation, the main purpose of which is to optimize the insertion path of the endoscope and reduce patient discomfort. In order to reduce the physical burden on medical staff caused by lifting the patient's jaw for a long time, special stents for continuous jaw lifting are widely used. This stent can continuously and stably maintain the proper position of the patient's jaw, allowing doctors to focus more on the examination process, while also providing patients with a more comfortable examination experience.

[0003] The existing mandibular support design usually imitates the manual support method, that is, when the patient lies flat, the support component in the support abuts against the mandibular angle, lifts up and fixes the mandible to a suitable angle. For example, a mandibular continuous support device for digestive endoscopy diagnosis and treatment with publication number CN215021492U points out that the upper and lower, left and right, front and back angles of the mandibular support can be flexibly adjusted through a flexible support tube and a universal ball head, so that the mandibular support can be used to lift the patient's mandible to a suitable angle when the patient is in a side-lying position, thereby optimizing the insertion path of the endoscope and reducing patient discomfort. However, sometimes it is necessary to The patient changes his body position to adapt to different diagnosis and treatment needs or to improve the diagnosis and treatment effect. When the patient's body position changes, the support point of the lifting bracket also needs to be readjusted. However, the movement of the bracket in this process will cause the position of the lifting component to change, causing it to shift from the mandibular angle. This position mismatch not only affects the stability of the mandibular support, but also causes discomfort to the patient and even affects the smoothness and safety of the endoscopic operation. Based on this, the present invention purposely provides a mandibular continuous support device for digestive endoscopic diagnosis and treatment, in which the support point of the bracket is fixed and the lifting component can still accurately support the mandibular angle after the patient's body position changes. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a mandibular continuous support device for digestive endoscopic diagnosis and treatment, so as to solve the technical problem that when the patient's body position changes, the position of the support bracket changes, resulting in the displacement of the mandibular angle of the patient by the support components thereon.

Each support plate is provided with a flexible support pad. The sides of the two support plates away from the shoulder pad are respectively connected to the two ends of the elastic rope.

[0006] As a further solution of the present invention: an angle is set between the support plate and the bearing frame, and the end where the two support plates are close to each other is the lower end.

[0008] As a further solution of the present invention: a locking module is provided at the rotation connection between the acute-angle U-shaped bracket and the sleeve and at the rotation connection between the movable end of the electric cylinder and the carrier frame.

[0009] As a further solution of the present invention: a card seat is provided on the carrier frame, a rotating bracket is rotatably installed on the acute-angle U-shaped bracket, a card joint is fixedly installed on one end of the rotating bracket, and the card joint is plugged into and matched with the card seat.

[0010] As a further solution of the present invention: a silicone pad is fixedly installed on the inner arc surface of the shoulder pad.

[0011] As a further solution of the present invention: the flexible support pad is designed as an arched structure.

[0012] As a further solution of the present invention: a flexible chin guard is fixedly connected to the elastic rope.

[0013] As a further solution of the present invention: a fixed block is fixedly installed on the carrier frame, the fixed block is located between the two support plates, and is located on the side of the carrier frame close to the elastic rope, a supporting plate is slidably installed on the fixed block, and the supporting plate is driven to move by a linkage assembly.

[0014] As a further solution of the present invention: the linkage assembly includes a spring and an eccentric wheel, the fixed block is connected to the support plate through the spring, the eccentric wheel is rotatably installed in the fixed block, it is driven to rotate by the second output source, and it abuts against the support plate.

[0015] Beneficial effects of the present invention: 1. In the present invention, the shoulder pads are placed on the shoulders of the patient on both sides to ensure that the inner arc surface of the shoulder pad fits the shoulders. At this time, the connecting section of the acute-angle U-shaped bracket is located on one side of the shoulder pad, the sleeve is located above the patient's neck, and the electric cylinder and the supporting frame are located below the patient's mandible. The electric cylinder pushes the supporting frame to move toward the mandibular angle of the patient. When the flexible support pads on the supporting plate abut against the mandibular angles on both sides of the patient, the elastic rope is clamped at the patient's chin to establish a connection between the patient's chin and the supporting plate. Subsequently, during the process of the supporting frame pushing the mandible to gradually rise, due to the action of the elastic rope, the mandible will rise and the connection between the supporting frame and the movable end of the electric cylinder will rotate, ensuring that the flexible support pad is always closely abutted against the mandibular angle of the patient. The setting of the shoulder pad and the acute-angle U-shaped bracket makes the supporting point of the overall device the patient's shoulder. When the patient changes his position, the shoulder will rotate synchronously with the head. The overall device is stationary relative to the patient's mandible, so it can ensure that the flexible support pad can continuously and accurately lift the mandible. 2. In the present invention, the two support plates are arranged obliquely, and the two support plates are similar to a "V" shape, so that the flexible support pads on the support plates can abut against the side of the mandibular angle. This design avoids directly abutting against the mandibular angle from the chin, thereby reducing the risk of touching the patient's submental area and reducing the patient's discomfort; 3. In the present invention, the driving source can push the sliding block to slide under the support plate, and the sliding block will drive the flexible support pad to slide on the support plate synchronously. This design allows the distance between the two support plates to be flexibly adjusted to adapt to the mandibular widths of different patients, especially the situation where the mandibular widths of children and adults are quite different. At the same time, the first output source can change the angle of the flexible support pad on the sliding block to further adapt to the differences in mandibular shapes of different patients. The precise adjustment of the position and angle of the flexible support pad ensures that the flexible support pad can more accurately support the mandibles of different patients.

[0016] 4. In the present invention, the patient's chin is doubly restricted by the elastic rope and the support plate, so that a more stable connection relationship is established between the patient's entire mandible including the chin and the support plate. This design effectively avoids the elastic rope from falling off the patient's chin, ensuring the safety and reliability of the entire device. In the subsequent process of the support frame pushing the mandible to gradually rise, it is ensured that the lifting action of the mandible can cause the connection between the support frame and the movable end of the electric cylinder to rotate, so that the flexible support pad is always in contact with the patient's mandibular angle, providing continuous support for the patient.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 8 As shown, the present invention is a mandibular continuous lifting device for digestive endoscopic diagnosis and treatment, comprising: The shoulder pad 2 has an acute-angle U-shaped bracket 1 fixedly mounted on its outer arc surface, a sleeve 101 is rotatably mounted on the connecting section of the acute-angle U-shaped bracket 1, and its connecting section is located on one side of the shoulder pad 2, the shoulder pad 2 is symmetrically arranged about the sleeve 101, an electric cylinder 3 is rotatably mounted in the sleeve 101, a bearing frame 4 is rotatably mounted on the movable end of the electric cylinder 3, and its movable end is away from the shoulder pad 2; There are two support plates 5 , which are symmetrically arranged on the carrier frame 4 . A flexible support pad 6 is provided on each support plate 5 . The sides of the two support plates 5 away from the shoulder pad 2 are respectively connected to two ends of an elastic rope 7 .

[0022] In one case of this embodiment, it should be noted that the electric cylinder 3 described in the present invention is a prior art, and the present invention does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0023] In actual application of this embodiment, the patient first takes a supine position, and the medical staff holds the acute-angle U-shaped bracket 1 with both hands, and places the shoulder pads 2 on both sides of the patient's shoulders to ensure that the inner arc surface of the shoulder pad 2 fits the shoulders. The connecting section of the acute-angle U-shaped bracket 1 is located on one side of the shoulder pad 2, the sleeve 101 is located above the patient's neck, and the electric cylinder 3 and the supporting frame 4 are located below the patient's lower jaw. At this time, the entire device is in Figure 4 In the state shown, since there is a certain angle between the mandible and the neck when the patient lies flat, the medical staff needs to manually rotate the support frame 4 to adapt it to the patient's physiological structure. After this operation, the whole device enters Figure 5 The preparation lifting stage shown in the figure, in this stage, the electric cylinder 3 is started to push the support frame 4 to move toward the mandibular angle of the patient until the flexible support pad 6 on the support plate 5 abuts against the mandibular angles on both sides of the patient. Then, the medical staff clamps the elastic rope 7 at the patient's chin and holds the patient's head with both hands. As the electric cylinder 3 continues to extend, the support frame 4 will push the mandible to gradually rise. In this process, due to the action of the elastic rope 7, the mandible is lifted up, which will cause the connection between the support frame 4 and the active end of the electric cylinder 3 to rotate, thereby ensuring that the flexible support pad 6 is always tightly abutted against the mandibular angle of the patient. This design avoids the situation where the contact area between the flexible support pad 6 and the mandibular angle is reduced or even separated due to the lifting of the mandibular angle. At the same time, the sleeve 101 will also rotate on the acute-angle U-shaped bracket 1 to change the overall direction of the electric cylinder 3 to adapt to the lifting action of the mandible; During the process of the patient's mandibular angle gradually tilting up, the medical staff guides the patient's head to move correctly with both hands until the mandibular angle is lifted to a suitable position and then stops the movement of the electric cylinder 3. At this time, the whole device is as follows: Figure 6 As shown, the continuous lifting stage is entered. In this stage, the patient's change of body position will not cause the position of the entire device to change, because the support point of the device is the patient's shoulder. When the patient lies on his side, the shoulder will rotate synchronously with the head, while the position of the entire device relative to the patient's mandible is stationary. Therefore, it can ensure that the flexible support pad 6 can continuously and accurately lift the mandible.

[0024] like Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, an angle is set between the support plate 5 and the carrier frame 4, and the end where the two support plates 5 are close to each other is the lower end.

[0025] In actual application, the two support plates 5 are arranged obliquely, and the two support plates 5 are similar to a "V" shape, so that the flexible support pad 6 on the support plate 5 can abut against the side of the mandibular angle. This design avoids abutting the mandibular angle directly from the chin, thereby reducing the risk of touching the patient's submental area and reducing the patient's discomfort.

[0026] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the flexible support pad 6 is slidably connected to the support plate 5, a slide groove 501 is provided on the support plate 5, and a sliding block 502 is slidably connected on the side away from the flexible support pad 6, the top of the sliding block 502 is rotatably connected to the bottom of the flexible support pad 6, and the connection between the two is located in the slide groove 501, a first output source for driving the flexible support pad 6 to rotate is provided in the sliding block 502, and a driving source for driving the sliding block 502 to move is provided on the support plate 5.

[0027] In one case of this embodiment, the first output source may be a servo motor, an electric motor or other components, or other mechanisms capable of achieving rotational motion; the driving source may be an electric telescopic rod, or other mechanisms capable of achieving linear reciprocating motion, which are not specifically limited in this embodiment.

[0028] In actual application of this embodiment, the driving source can push the sliding block 502 to slide under the support plate 5, and the sliding block 502 will drive the flexible support pad 6 to slide on the support plate 5 synchronously. This design allows the distance between the two support plates 5 to be flexibly adjusted to adapt to the mandibular widths of different patients, especially the situation where the mandibular widths of children and adults are quite different. At the same time, the first output source can change the angle of the flexible support pad 6 on the sliding block 502 to further adapt to the differences in mandibular shapes of different patients. The precise adjustment of the position and angle of the flexible support pad 6 ensures that the flexible support pad 6 can more accurately support the mandibles of different patients. In actual applications, medical staff can adjust the position and angle of the flexible support pad 6 according to the specific conditions of the patients to achieve the best treatment effect.

[0029] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the rotation connection between the acute-angle U-shaped bracket 1 and the sleeve 101 and the rotation connection between the movable end of the electric cylinder 3 and the supporting frame 4 are both provided with locking modules.

[0030] In one case of this embodiment, it should be noted that the locking modules described in the present invention are prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0031] In actual application of this embodiment, during the continuous lifting stage, the relative positions of the sleeve 101 and the carrier 4 are firmly fixed by the locking module. This fixing measure ensures that a rigid connection is formed between the carrier 4 and the movable end of the electric cylinder 3, thereby prohibiting any rotation between the two. At the same time, the connection point between the sleeve 101 and the acute-angle U-shaped bracket 1 is also firmly locked, and no rotation is allowed to occur. Under such a configuration, the acute-angle U-shaped bracket 1, the electric cylinder 3 and the carrier 4 together constitute an extremely stable bracket. The main function of this bracket is to continuously and stably support the patient's mandible. Since the stability of the bracket is fully guaranteed, the bracket system can always maintain its position unchanged during the entire lifting process, thereby effectively ensuring the stability of the patient's head. In addition, since the bracket forms a fixed whole, it can also reduce any shaking or instability factors that occur during the lifting process.

[0032] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, a snap-in seat 10 is provided on the carrier frame 4, a rotating bracket 9 is rotatably installed on the acute-angle U-shaped bracket 1, a snap joint 11 is fixedly installed at one end of the rotating bracket 9, and the snap joint 11 is plugged into and matched with the snap-in seat 10.

[0033] In actual application of this embodiment, when the device is idle, each rotating joint is locked by the locking module, and the rotating bracket 9 is rotated so that the clamping joint 11 at one end of the rotating bracket 9 is inserted into the clamping seat 10. At this time, the supporting frame 4 and the acute-angle U-shaped bracket 1 are supported by the rotating bracket 9, thereby adding additional support points and improving the stability of the device when it is placed.

[0034] like Figure 1 As shown, as a preferred embodiment of the present invention, a silicone pad 201 is fixedly installed on the inner arc surface of the shoulder pad 2.

[0035] In actual application of this embodiment, through the provision of the silicone pad 201, when the shoulder pad 2 abuts against the patient's shoulder, the silicone pad 201 will be deformed. This deformation not only improves the fit with the patient's shoulder, but also enhances the patient's comfort. The softness and elasticity of the silicone pad 201 enable it to adapt to the shoulder shape and size of different patients, thereby providing a more personalized treatment experience. At the same time, the silicone pad 201 also has good air permeability and moisture absorption, which helps to reduce the patient's discomfort during treatment.

[0036] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the flexible support pad 6 is designed as an arched structure.

[0037] In actual application of this embodiment, the flexible support pad 6 adopts an arched structure design. This design can ensure that the deformation generated by itself will not abut the lymph nodes of the patient's chin after abutting against the mandible, thereby avoiding causing discomfort to the patient.

[0038] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, a flexible chin guard 8 is fixedly connected to the elastic rope 7.

[0039] In actual application, the contact area between the flexible chin guard 8 and the patient's chin is significantly enlarged through the careful design and configuration of the present embodiment. This enlarged contact area not only improves the wearing comfort, but also greatly enhances the stability, ensuring that when the patient's lower jaw is raised, the support frame 4 can be more stably driven to rotate accurately and smoothly.

[0040] like Figure 7-Figure 8 As shown, as a preferred embodiment of the present invention, a fixed block 12 is fixedly installed on the carrier frame 4, and the fixed block 12 is located between the two support plates 5, and is located on the side of the carrier frame 4 close to the elastic rope 7, and a supporting plate 13 is slidably installed on the fixed block 12, and the supporting plate 13 is driven to move by a linkage assembly.

[0041] In one case of this embodiment, round rods are fixedly installed at the four corners of the supporting plate 13 , and the round rods are slidably inserted into the fixing block 12 .

[0042] In actual application of this embodiment, when the entire device is in the stage of preparing for lifting, the medical staff first presses the flexible support pads 6 on the support plate 5 against the mandibular angles on both sides of the patient to ensure the comfort and stability of the patient in subsequent operations. Then, the medical staff clamps the elastic rope 7 above the patient's chin. At this time, the support plate 13 is located below the patient's chin. Next, the support plate 13 is driven to move through the linkage component so that it gradually presses against the patient's chin. In this process, the patient's chin is doubly restricted by the elastic rope 7 and the support plate 13, thereby establishing a more stable connection relationship with the carrier 4. This design has the advantages of The elastic rope 7 is effectively prevented from falling off the patient's chin, ensuring the safety and reliability of the entire device. In the subsequent process of the support frame 4 pushing the mandible to gradually rise, the lifting action of the mandible will cause the connection between the support frame 4 and the movable end of the electric cylinder 3 to rotate, so the flexible support pad 6 is always in contact with the patient's mandibular angle, providing continuous support for the patient; at the same time, the round rod on the support plate 13 is always sliding in the fixed block 12. This design improves the stability of the movement of the support plate 13, ensuring that it always performs linear reciprocating movement, thereby providing a smooth and comfortable lifting experience for the patient.

[0043] like Figure 7-Figure 8As shown, as a preferred embodiment of the present invention, the linkage assembly includes a spring 14 and an eccentric wheel 15, the fixed block 12 is connected to the support plate 13 through the spring 14, the eccentric wheel 15 is rotatably installed in the fixed block 12, and is driven to rotate by the second output source, and is in contact with the support plate 13.

[0044] In one case of this embodiment, the second output source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0045] In practical application, if Figure 8 As shown in the figure, at this time, the rotating shaft of the eccentric wheel 15 is close to the supporting plate 13. When the second output source drives the eccentric wheel 15 to rotate 180 degrees clockwise, the rotating shaft of the eccentric wheel 15 will be away from the supporting plate 13, that is, the supporting plate 13 is away from the fixing block 12 under the action of the eccentric wheel 15. At this time, the supporting plate 13 can abut against the patient's chin, and when the second output source continues to drive the eccentric wheel 15 to rotate back Figure 8 In the state shown, under the pulling force of the spring 14 , the supporting plate 13 will approach the fixing block 12 , and the supporting plate 13 will be away from the patient's chin, so that the movement of the supporting plate 13 can be controlled by the rotation of the eccentric wheel 15 .

[0046] Working principle of the present invention: The above embodiment of the present invention provides a mandibular continuous lifting device for digestive endoscopic diagnosis and treatment. The patient first takes a supine position, and the medical staff holds the acute-angle U-shaped bracket 1 with both hands and places the shoulder pads 2 on the patient's shoulders on both sides to ensure that the inner arc surface of the shoulder pad 2 fits the shoulders. The connecting section of the acute-angle U-shaped bracket 1 is located on one side of the shoulder pad 2, and the sleeve 101 is located above the patient's neck, while the electric cylinder 3 and the supporting frame 4 are located below the patient's mandible. Because there is a certain angle between the patient's mandible and the neck when the patient lies flat, the medical staff needs to manually rotate the supporting frame 4 to adapt it to the patient's physiological structure. After this operation, the electric cylinder 3 is started to push the supporting frame 4 to move toward the patient's mandibular angle until the flexible support pads 6 on the supporting plate 5 abut against the patient's mandibular angles on both sides. Subsequently, the medical staff clamps the elastic rope 7 at the patient's chin and holds the patient's head with both hands. As the electric cylinder 3 continues to extend, the supporting frame 4 will push the mandible to gradually rise up. In this process, due to the elastic Due to the action of the sex rope 7, the mandibular tilt will cause the connection between the support frame 4 and the movable end of the electric cylinder 3 to rotate, thereby ensuring that the flexible support pad 6 is always in close contact with the patient's mandibular angle. This design avoids the situation where the mandibular angle is tilted, resulting in a reduction in the contact area between the flexible support pad 6 and the mandibular angle, or even separation. At the same time, the sleeve 101 will also rotate on the acute-angle U-shaped bracket 1, changing the overall direction of the electric cylinder 3 to adapt to the mandibular tilt movement. In the process of the patient's mandibular angle gradually tilting up, the medical staff will use both hands to guide the patient's head to move correctly until the mandibular is lifted to a suitable position, then stop the movement of the electric cylinder 3 and enter the continuous lifting stage. In this stage, the patient's change of body position will not cause the position of the entire device to change, because the support point of the device is the patient's shoulder. When the patient lies on his side, the shoulder will rotate synchronously with the head, and the position of the entire device relative to the patient's mandible is stationary. Therefore, it can ensure that the flexible support pad 6 can continuously and accurately lift the mandible.

[0047] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
