Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a support block assembly of a mandibular positioner. Background Art

[0002] At present, in clinical practice, when patients are given general anesthesia or sedatives are administered in a conscious state, the tongue root falls back and blocks the airway. At this time, medical staff need to take measures to open the patient's airway and maintain airway patency to avoid shortness of breath or suffocation. The most commonly used method to solve the above problems clinically is the manual jaw support method, which is to support the face with the thumbs of both hands, and then hold the mandibular angle with the middle finger and / or ring finger and lift it up, so that the patient's head is tilted back. The jaw support method can effectively open the airway and quickly restore the patient's breathing. Although this manual method is easy to operate, it requires medical staff to hold the patient's mandibular angle for a long time during clinical application, which can easily cause fatigue of medical staff, and it will also occupy medical staff and affect the operating efficiency of the hospital.

[0003] In order to solve this problem, the existing technology mainly uses a mandibular support device to assist medical staff to solve the above problem. For example, the Chinese utility model patent with publication number CN216725124U discloses a semi-fixed mandibular support device. It includes a support structure and a support assembly; the support structure includes a relatively arranged base, the support mechanism includes a support pad body located above the base, and a lifting mechanism fixed to the upper end of the base for adjusting the height of the support pad body is provided below the support pad body, and a mounting sleeve is provided at the upper end of the lifting mechanism, and the mounting sleeve is rotatably matched with the support pad body. The support structure in the above-mentioned semi-fixed mandibular support device can move relatively and adjust the position and stability of the base as needed, and can effectively support the patient's mandible, replacing the manual operation of medical staff, freeing the hands of doctors and medical staff, and facilitating better intraoperative anesthesia management.

[0004] However, in the prior art, the support parts of the mandibular angle of the patient are mostly plastic parts with hooks or columnar plastic parts, and the mandibular angle is supported by the hook pulling the mandibular angle or the column lifting the mandibular angle. Although the above-mentioned support parts can effectively support the mandibular angle, there will be a problem of high local pressure at the mandibular angle of the patient during clinical use. Once the operation time is long, it will cause indentation on the mandibular angle of the patient, and even cause iatrogenic damage. Utility Model Content

[0033] The present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] The present application is a component installed on a bracket-type mandibular supporting device, which is used to directly contact the mandibular angle of a human body and provide a lifting force to the mandibular angle of a human body when in use.

[0035] like Figure 3 As shown, the present application designs a support block assembly of a mandibular positioner, the support block assembly of the mandibular positioner includes a pair of symmetrical mandibular angle support block assemblies 1, the mandibular angle support block assembly 1 includes a connecting rod 11 and a mandibular angle support block plate 12, one end of the connecting rod 11 is fixedly connected to one side of the mandibular angle support block plate 12, and the other side of the mandibular angle support block plate 12 is fixedly provided with a cushion 13. The connecting rod 11 and the mandibular angle support block plate 12 can be made of plastic material, and the cushion 13 can be made of silicone or other soft materials. To prepare the support block assembly of the mandibular positioner of the present application, plastic masterbatch can be used as raw material, and the connecting rod 11 and the mandibular angle support block plate 12 can be prepared by an integrated molding process, and then the cushion 13 can be prepared separately, and finally the cushion 13 can be attached to the mandibular angle support block plate 12 by bonding or ultrasonic welding.

[0036] like Figure 1 and Figure 2 As shown in the human mandibular anatomy diagram, the mandibular angles are located on both sides of the mandibular bone. Figure 1 As shown in the figure, at the outer edge of the mandible, the direction along the mandibular ramus to the mandibular angle to the outer edge of the mandibular floor is the outer edge direction of the mandibular angle. Figure 2 As shown, on the normal section at the mandibular angle in the outer direction of the mandibular angle, the circumferential direction of the mandibular angle is from the bottom of the mandibular angle along the outer side of the masseter muscle.

[0037] like Figure 3 As shown, the support block assembly of the mandibular positioner of the present application will be assembled to the two side columns of the mandibular positioner 2 when in use.

[0038] The mandibular angle support plate 12 of the present application is an cambered body, and its direction of fitting with the outer edge of the mandibular angle and the direction of fitting with the peripheral edge of the mandibular angle are both arc-shaped. The present application adopts a bionic design, and the curvature of the mandibular angle support plate 12 in the direction of fitting with the outer edge of the mandibular angle and the direction of fitting with the peripheral edge of the mandibular angle are respectively adapted to the curvature of the outer edge direction and the peripheral direction of the mandibular angle of the human body. The soft pad 13 of the present application is also an cambered body, and its shape is adapted to the mandibular angle support plate 12.

[0039] like Figure 4 As shown, the structural relationship between the connecting rod 11 and the mandibular angle support plate 12 of the present application must meet the following spatial position and angle conditions. With the mandibular angle support block assembly 1 as a reference, a rectangular coordinate system is constructed, and the rectangular coordinate system has X, Y, Z axes and a coordinate origin Q; the rectangular coordinate system uses the central axis of the connecting rod 11 as the X-axis, the horizontal plane as the XY plane, the Y axis is perpendicular to the X-axis, and the connection point between the connecting rod 11 and the mandibular angle support plate 12 as the coordinate origin Q. Figure 5 As shown, in the rectangular coordinate system constructed above, the arc line of the mandibular angle support plate 12 drawn along the fitting direction of the mandibular angle support plate 12 and the mandibular angle periphery is the scanning curve. Figure 6 and Figure 7 As shown, in the rectangular coordinate system constructed above, the arc line of the mandibular angle support plate 12 outlined along the direction of the mandibular angle support plate 12 fitting the outer edge of the mandibular angle is the scanning trajectory curve. In the rectangular coordinate system constructed above, the arc surface of the mandibular angle support plate 12 of the present application is obtained by scanning the scanning curve after scanning the scanning trajectory curve.

[0040] like Figure 5 As shown, the mandibular angle support block assembly 1 is rotated and adjusted along the X-axis so that the scanning trajectory curve is tangent to the XY horizontal plane at the coordinate origin Q. At this time, the scanning curve located at the coordinate origin Q is exactly located on the normal section of the scanning trajectory curve at the coordinate origin Q; and the projection line of the scanning trajectory curve located at the coordinate origin Q on the XY horizontal plane is a straight line.

[0041] Based on the above position reference, Figure 5 As shown, the angle between the tangent line of the scanning curve at the coordinate origin Q and the XY plane is set to α; Figure 6 As shown, the angle between the projection line of the scanning trajectory curve on the XY horizontal plane and the Y axis is set to θ. The angle relationship between the connecting rod 11 and the mandibular angle support plate 12 needs to satisfy α is 0º~60º, and θ is 10º~50º.

[0042] Prior to this application, the prior art disclosed various mandibular support devices, which are mainly divided into two categories. One is the hook type, in which the shape of the support component of the mandibular angle is similar to a hook, and when used, the mandibular angle is hooked, and the mandibular angle is supported by providing an upward pulling force to the hook type support component; the other is the lifting type, which has a structure similar to that of the support component. Figure 3 The structure of the mandibular positioner in is similar to that of the conventional mandibular support device. Columns are arranged on both sides of the patient's head, and supporting components are installed on the columns. The supporting components are plate-shaped or column-shaped. When in use, they support the mandibular angle and use the reaction force generated when the weight of the human head presses down the supporting components to support the mandibular angle. The supporting components used in these prior art mandibular support devices are mostly designed for functional needs. Since they are used for patients with general anesthesia, they do not take into account the comfort during use and the problems caused by long-term compression of the mandibular angle.

[0043] The applicant has found in actual clinical practice that for some patients with sensitive skin, using the existing mandibular support device will cause pressure marks on the mandible after more than ten minutes of use, and the patient will also feel discomfort in the mandible after waking up from anesthesia.

[0044] In addition, the applicant also found that patients who are clinically administered intravenous sedatives and analgesics are also prone to tongue root fall back, causing breathing difficulties when lying down. During hospitalization, such patients need to monitor indicators such as blood oxygen saturation, and they also need to lift the mandible to open the airway when they have breathing difficulties. For such patients, the use of a mandibular support device during rest during hospitalization can effectively avoid the above problems and can greatly reduce the consumption of medical staff. However, these patients are not anesthetized patients and are generally in a state of consciousness. Problems such as discomfort caused by the use of existing mandibular support devices will seriously affect the patient's rest. Even if the use of analgesics relieves the patient's discomfort, long-term use will cause iatrogenic injuries to the patient.

[0045] Based on the above clinical research, the applicant has designed the support block assembly of the mandibular positioner of the present application. The design of the present application is made after combining the bionic structure of the human mandible and the mechanical analysis of the mandibular angle support. When the present application is used, in addition to being able to better fit the mandibular angle of the patient and avoid patient discomfort caused by excessive local stress, it can also better disperse the pressure generated by the support and avoid stress trauma.

[0069] The mandibular support device prepared as above was used as a sample and the same usage test as in Example 1 was carried out.

[0070] Test results: 30 subjects had no indentation on their jaws after using it for 10 minutes; 50% of the subjects had slight indentation on their jaws after using it for 30 minutes; all subjects had indentation on their jaws after using it for 60 minutes; the indentation on all subjects disappeared naturally 24 hours after the end of the test. After the end of the test, 60% of the 30 subjects reported that they had a tolerable mild pain during use.

[0071] It can be seen from the test results of Example 1, Example 2, and Comparative Tests 1 to 2 that the support block assembly of the mandibular positioner of the present application, after adopting a specific structural design, can significantly reduce the discomfort of patients during use, effectively reduce the incidence of indentation during use, and can effectively provide certain protection for the mandible during use.

[0072] On the basis of the above-mentioned embodiments, the applicant conducted an experimental study on the size parameters of the mandibular angle support plate 12 based on Embodiment 1.

[0073] Through the results of experiments and tests, the size of the mandibular angle support plate 12 of Example 1 is adopted, when the mandibular angle support plate 12 is in an arc shape with the outer edge of the mandibular angle, and the arc radius Ra is 30~80mm; the mandibular angle support plate 12 is in an arc shape with the peripheral edge of the mandibular angle, and the arc radius Rb is 15~50mm, the technical effect of the present application can be achieved. When the arc radius Ra is 45~55mm and the arc radius Rb is 25~30mm, the comfort of use is more significantly improved, and the incidence of indentation is also significantly reduced.

[0074] In addition, through the results of experiments and tests, when the arc-shaped mandibular angle support plate 12 of Example 1 is adopted, the length of the mandibular angle support plate 12 in the direction of fitting with the outer edge of the mandibular angle is 60~80mm, and the length of the mandibular angle support plate 12 in the direction of fitting with the peripheral edge of the mandibular angle is 30~50mm, the comfort of use is relatively better.

[0075] On the basis of the above-mentioned embodiments, the applicant conducted an experimental study on the angle parameters between the mandibular angle support plate 12 and the connecting rod 11 based on Embodiment 2.

[0076] Through the results of experiments and tests, the mandibular angle support plate 12 of the present application can achieve the technical effect of the present application when θ is 0º~60º and α is 20º~70º. When the mandibular angle support plate 12 of the present application has θ of 10º~30º and α of 30º~50º, the comfort of use is more significantly improved, and the incidence of indentation is also significantly reduced.

[0077] Example 3

[0078] The support block assembly of the mandibular positioner of this embodiment is basically the same as that of the embodiment 2, except that a groove is provided on the cushion 13 of this embodiment. The groove size of this embodiment is 50×12 mm, and the depth of the groove is 2.5 mm.

[0079] The solution of this embodiment is mainly aimed at obese patients, and the main purpose of providing the groove is to enable the mandibular angle support plate 12 and the cushion 13 to better fit the mandibular angle of obese patients.

[0080] The support block assembly of the mandibular positioner of this embodiment was subjected to the same usage test as that of embodiment 1.

[0081] Test results: 30 subjects had no indentation on their jaws after using it for 10 minutes; 23% of the subjects had slight indentation on their jaws after using it for 30 minutes; 43% of the subjects had indentation on their jaws after using it for 60 minutes; the indentation on all subjects disappeared naturally 24 hours after the test. After the test, 17% of the 30 subjects reported that they had a tolerable mild pain during use.

[0082] According to the test results of Example 3, it can be seen that after the groove is opened on the soft pad 13, the present application can better fit the mandible of obese patients, but the incidence of indentation will also increase. Therefore, the solution of this embodiment should be used exclusively for patients with facial obesity.

[0083] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
