Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary devices, and in particular relates to an auxiliary system for repositioning and fixing a temporomandibular joint and a method of using the system. Background Art

[0002] The temporomandibular joint is a left-right linkage joint in the maxillofacial region that has rotational and sliding movements. Its anatomy and movement are among the most complex joints in the human body. The main functions of the temporomandibular joint are to participate in chewing, speech, swallowing, and expression. During chewing, the joint is under pressure, while during speech, singing, and expression, the joint movement needs to be very flexible. Therefore, the anatomical structure of the temporomandibular joint is both stable and flexible. During the movement, if the condyle slips out of the joint fossa, beyond the normal limit of joint movement, and cannot return to its original position by itself, it is a dislocation of the temporomandibular joint. Since the temporomandibular joint is the only linkage joint in the body, it has its own particularity. According to the location, it can be divided into unilateral dislocation and bilateral dislocation. According to the direction and position of the condyle dislocation, it can be divided into anterior dislocation, posterior dislocation, superior dislocation, and lateral dislocation. Therefore, temporomandibular joint dislocation is not a simple and single situation, but may occur in complex situations such as bilateral anterior dislocation, unilateral anterior dislocation, bilateral posterior dislocation, and unilateral posterior dislocation. For different types of temporomandibular joint dislocation, clinical treatment is often carried out by manual reduction, surgical reduction and medical device-assisted reduction. Reduction needs to be performed according to the patient's specific situation. Secondly, clinically, temporomandibular joint reduction requires greater force and the patient's body position needs to cooperate. Clinically, patients are often required to sit on a small stool against the wall, with their backs against the wall and their jaws flush with the doctor's elbows for easy force. Doctors are prohibited from using violence when exerting force to protect the temporomandibular joint ligaments and muscles and prevent secondary injuries. After reduction, use a bandage to fix the mandible in time to prevent dislocation again.

[0003] In summary, when reducing temporomandibular joint dislocation, the improvement method must be implemented according to the patient's actual situation. At the same time, sufficient force must be provided, violence must be prohibited to prevent secondary injury, and the reduction needs of patients in special positions must be met. After reduction, the mandible must be fixed in time to prevent dislocation again.

[0004] According to the above requirements, the current treatment methods commonly used in clinical reduction of temporomandibular joint dislocation, such as manual reduction, surgical reduction and medical device-assisted reduction, have the following four shortcomings:

[0005] (1) Insufficient force makes it impossible to complete reduction, while greater force causes secondary injury. The most commonly used reduction method in clinical practice is manual reduction. However, in clinical work, greater force is often required to successfully reduce the temporomandibular joint dislocation, especially when it occurs in young people. However, in clinical practice, female doctors have less force and often cannot reduce the temporomandibular joint. Some male doctors have greater force and the mandible moves downward to a greater extent, which leads to further aggravation of muscle and ligament injuries and prolonged recovery time even after reduction.

[0006] (2) Unable to perform reduction according to patient needs. Most reduction instruments are only suitable for the treatment of a small number of patients with bilateral anterior dislocation. The target population is small and it is difficult to meet clinical application requirements. Moreover, most reduction instruments cannot sense whether the temporomandibular joint has reached the optimal downward position. If it continues to move downward beyond this position, the muscle and ligament damage will be aggravated after reduction, and in severe cases, habitual dislocation may even occur.

[0007] (3) Unable to reposition patients in special positions. In clinic, paralyzed patients, trauma patients, and patients with severe kyphosis often suffer from temporomandibular joint dislocation. Patients cannot be repositioned according to routine operations. Even strong male doctors rarely succeed in repositioning patients who lie flat or on their sides. In this case, surgical repositioning is required under general anesthesia. However, surgical repositioning under general anesthesia for such patients is risky and expensive, which increases the pain and burden of patients.

[0008] (4) Failure to fix the mandible in time leads to re-dislocation. After the temporomandibular joint dislocation is reduced, the mandible must be fixed in time, otherwise it may dislocate again. After reduction, clinicians use bandages to fix the mandible, which requires a certain amount of preparation time, is time-consuming, laborious and uncomfortable.

[0009] In view of this, this invention is proposed. Summary of the invention

[0010] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and to provide an auxiliary system for the reduction and fixation of the temporomandibular joint and a method of using the system. When reducing the temporomandibular joint dislocation, the system can be implemented according to the actual situation of the patient. At the same time, the force is controllable, which can meet the reduction needs of patients with special body positions. After reduction, the mandible can be fixed in time to prevent dislocation again.

[0011] The purpose of the present invention is to be solved by the following technical solutions:

[0012] On the one hand, the present invention provides an auxiliary system for repositioning and fixation of the temporomandibular joint, including an auxiliary pressurizing device, which is arranged between an upper and a lower mandibular support, wherein the upper mandibular support is arranged in the upper molar area, and the lower mandibular support is arranged in the lower molar area, the upper mandibular support is fixed to one end of a connecting rod, and the other end of the connecting rod is fixed on a top cap arranged on the top of the head by passing around the patient's face, the top cap is detachably connected to a restraint belt wrapped around the head, and one end of the auxiliary pressurizing device connected to the upper mandibular support is also connected to a pressure display and a pressurizing system through a pipeline.

[0013] Furthermore, the auxiliary pressurizing device includes: a first universal ball fixed on the maxillary support, a metal tube passing through the first universal ball, one end of the metal tube connected to the pipeline and the other end connected to the hydraulic device, and the lower end of the hydraulic device is connected to the second universal ball fixed on the mandibular support through a metal rod.

[0014] Furthermore, a first spring and a first hydraulic rod are installed in the hydraulic device, and the lower end of the first hydraulic rod is connected to a metal rod.

[0015] Furthermore, the pressurizing system includes an oil reservoir, a pressurizing device and a valve switch. The two ends of the oil reservoir are respectively connected to the pressurizing device and the valve switch. By pressing the pressurizing device, the hydraulic oil in the oil reservoir flows along the pipeline into the auxiliary pressurizing device. By pressing the valve switch, the hydraulic oil in the auxiliary pressurizing device flows along the pipeline into the oil reservoir.

[0016] Furthermore, the pressurizing device is a foot-operated structure, comprising: a resilient plastic barrel, a second hydraulic rod, a second spring and a foot-operated plate. The bottom of the resilient plastic barrel is fully open, and a second spring and a second hydraulic rod are arranged in the resilient plastic barrel. The upper end of the second hydraulic rod extends out of the upper end of the resilient plastic barrel and is connected to the foot-operated plate. The two ends of the bottom of the resilient plastic barrel are respectively connected to the oil reservoir and the auxiliary pressurizing device through pipes. A second one-way valve is arranged between the resilient plastic barrel and the oil reservoir, and a first one-way valve is arranged between the resilient plastic barrel and the auxiliary pressurizing device.

[0017] Furthermore, the pressurizing system includes a motor, an oil pump, a control switch and an oil storage tank, the control switch includes a first control switch and a second control switch, one end of the first control switch and the second control switch are both connected to the auxiliary pressurizing device, and the other ends are respectively connected through the first oil pump, the second oil pump and the oil storage tank, the first oil pump is connected to the first motor, and the second oil pump is connected to the second motor. By pressing the first control switch, the first oil pump and the first motor are driven to operate, and the hydraulic oil in the oil storage tank is transported to the auxiliary pressurizing device along the pipeline. By pressing the second control switch, the second oil pump and the second motor are driven to operate, and the hydraulic oil in the auxiliary pressurizing device is transported to the oil storage tank along the pipeline; a third one-way valve is provided on the pipeline connected to the first control switch, and a fourth one-way valve is provided on the pipeline connected to the second control switch.

[0018] Furthermore, the pressure display is of a dropper type, with a marking scale on the outside and a marking ball on the inside, and the scale difference moved by the marking ball corresponds to the downward movement distance of the first hydraulic rod in the auxiliary pressurizing device.

[0019] Furthermore, fixed wings are provided on both sides of the top cap, and the restraint belt comprises an upper restraint belt and a lower restraint belt. The middle part of the upper restraint belt is connected to the fixed wing by a net bag or is connected to the fixed wing by a zipper. There are two fixing straps on both sides of the upper restraint belt, and the two fixing straps on the same side extend from the front and back sides of the patient's ears to the mandible respectively. The lower restraint belt wraps the patient's mandible from the chin to the mandible as a whole and extends upward. The upper restraint belt and the lower restraint belt are connected by Velcro.

[0020] Furthermore, the connecting rod is composed of a sliding rod, a slideway and a fixed knob. The sliding rod can slide arbitrarily along the length direction of the slideway to adjust the length of the connecting rod. The fixed knob fixedly connects the sliding rod and the slideway.

[0021] On the other hand, the present invention also provides a method for using an auxiliary system for temporomandibular joint reduction and fixation, based on the auxiliary system for temporomandibular joint reduction and fixation, comprising the following steps:

[0022] Step 1: fix the restraint belt and the top cap to the patient's head in sequence, place the maxillary support and the mandibular support in the patient's mouth, and connect the top cap and the maxillary support with a connecting rod.

[0023] Step 2: Place the auxiliary pressurizing device between the maxillary support and the mandibular support.

[0024] Step 3, pressurize the pressurization system, and when the pressure reaches the set value, stop pressurizing, remove the auxiliary pressurization device, and secure the restraint belt again.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) Auxiliary force can achieve controllable force, which can effectively prevent secondary injury: The auxiliary system of the present invention plays the role of auxiliary force during use, and the auxiliary force can display the moving distance of the auxiliary pressure device according to the pressure display. If the patient is examined by CT or B-ultrasound before reduction, the direction and distance of movement of the left and right sides can be measured, and the reduction can be more accurate when using this auxiliary device. If no examination is performed, the doctor needs to feel the position of the temporomandibular joint when using this device for empirical reduction, effectively control the force and can intuitively observe the moving distance, thereby effectively avoiding violent reduction and preventing secondary injury;

[0027] (2) It can be implemented according to the actual situation of the patient: The auxiliary system of the present invention is obviously different from most reduction instruments through the design of a universal ball. The force direction and angle can be adjusted arbitrarily in the patient's mouth. Therefore, whether it is a complex situation such as bilateral anterior dislocation, unilateral anterior dislocation, bilateral posterior dislocation, unilateral posterior dislocation, etc., the present invention can apply force from different angles and directions according to the specific situation of the patient to complete the reduction requirement;

[0028] (3) Ability to meet the needs of patients in special body positions: The auxiliary system of the present invention is not affected by body position. Even if the patient is paralyzed and lying in bed, force can be effectively applied to perform repositioning, thus getting rid of the disadvantage of weak force in manual repositioning. At the same time, it reduces the economic burden of some patients who need surgical repositioning and avoids surgical risks.

[0029] (4) Timely fixation after reduction to prevent re-dislocation: After the auxiliary system of the present invention completes the reduction, the patient's mandible can be immediately restrained and fixed with a restraint belt, avoiding the tedious steps of searching for materials and instruments for fixation again, and greatly reducing the risk of re-dislocation of the temporomandibular joint.

[0030] In summary, compared with the prior art, the auxiliary system for temporomandibular joint reduction and fixation provided by the present invention is a professional medical auxiliary device that can be implemented according to the actual situation of the patient, has controllable force, can meet the reduction needs of patients in special body positions, and can promptly fix after reduction to prevent re-dislocation.

A threaded hole 4 is provided at the connection between the top cap 3 and the connecting rod 6, and the connecting rod 6 and the top cap 3 are connected by screws to ensure the stability of the connection between the two.

[0050] According to an embodiment of the present invention, Figure 6 As shown, the auxiliary pressurizing device of the present invention is installed between the upper and lower jaw supports. The auxiliary pressurizing device is arranged between the upper and lower jaw supports, the upper jaw support 8 is arranged in the upper molar area, and the lower jaw support 13 is arranged in the lower molar area. The auxiliary pressurizing device comprises: a first universal ball 10 fixed on the upper jaw support 8, a metal tube 9 passing through the first universal ball 10, one end of the metal tube 9 is connected to a pipeline, and the other end is connected to a hydraulic device, and the lower end of the hydraulic device is connected to a second universal ball 14 fixed on the lower jaw support 13 through a metal rod.

Since the first hydraulic rod 12 is directly connected to the metal rod on the mandibular support 13, the downward movement distance of the first hydraulic rod 12 is the distance that the mandibular support 13 is pressed downward.

[0052] According to an embodiment of the present invention, Figure 8-9 As shown, the present invention provides two connection structures of pressurizing systems, namely a human-assisted pressurizing system and an electric-assisted pressurizing system. The liquid in the oil reservoir 24 or the oil tank 25 can be delivered or recovered by continuously stepping on the switch to achieve the auxiliary force process. The pressurizing system can be divided into human-assisted pressurizing and electric pressurizing to adapt to different application scenarios.

[0053] in, Figure 8 The schematic diagram of the structure of the human-assisted pressurizing system is shown in FIG. The pressurizing system includes an oil reservoir 24, a pressurizing device and a valve switch 18. The two ends of the oil reservoir 24 are connected to the pressurizing device and the valve switch 18 respectively. By pressing or stepping on the pressurizing device, the hydraulic oil in the oil reservoir 24 flows into the auxiliary pressurizing device along the pipeline.

The two ends of the bottom of the resilient plastic barrel 20 are respectively connected to an oil reservoir 24 and an auxiliary pressurizing device through pipelines. A second one-way valve 23 is arranged between the resilient plastic barrel 20 and the oil reservoir 24, and a first one-way valve 22 is arranged between the resilient plastic barrel 20 and the auxiliary pressurizing device.

[0054] and Fig. 9The schematic diagram of the structure of the electric auxiliary pressurizing system is shown in FIG. The pressurizing system includes a first motor 26, a first oil pump 27, a second motor 32, a second oil pump 33, a control switch and an oil storage tank 25. The control switch includes a first control switch 28 and a second control switch 30. One end of the first control switch 28 and the second control switch 30 are connected to the auxiliary pressurizing device, and the other end is connected to the oil storage tank 25 through the first oil pump 27. The first oil pump 27 is connected to the first motor 26. By pressing the first control switch 28, the first oil pump 27 and the first motor 26 are driven to operate. The hydraulic oil in the oil storage tank 25 is transported to the auxiliary pressurizing device along the pipeline. By pressing the second control switch 30, the second oil pump 32 and the second motor 33 are driven to operate, and the hydraulic oil in the auxiliary pressurizing device is transported to the oil storage tank 25 along the pipeline. A third one-way valve 29 is provided on the pipeline connected to the first control switch 28. When the first control switch 28 is stepped on, the third one-way valve 29 is opened at the same time. A fourth one-way valve 31 is provided on the pipeline connected to the second control switch 30. When the second switch 30 is stepped on, the fourth one-way valve 31 is opened at the same time. The electric pressurizing system can realize forward and reverse rotation through the two sets of motors installed, and realize the liquid transportation or recovery in the oil storage tank 25 by continuously stepping on the switch.

[0055] On the other hand, the present invention also provides a method for using an auxiliary system for temporomandibular joint reduction and fixation, based on the auxiliary system for temporomandibular joint reduction and fixation, comprising the following steps:

[0056] Step 1, fix the restraint belt and the top cap 3 to the patient's head in sequence, place the maxillary support 8 and the mandibular support 13 in the patient's mouth, and connect the top cap 3 and the maxillary support 8 through the connecting rod 6. After the auxiliary pressurizing device is tightly fitted to the maxilla through the maxillary support 8, connect the connecting rod 6 and adjust the length and distance so that the top cap 3 and the auxiliary pressurizing device are stably installed.

[0057] Step 2: Place the auxiliary pressurizing device between the maxillary support 8 and the mandibular support 13. The metal tube 9 passes through the first universal ball 10 on the maxillary support 8 and is connected to the pipeline. The pipeline is connected to the pressure display 15 and the pressurizing system in turn.

[0058] Step 3, pressurize the pressurizing system, and when the pressure reaches the set value, stop pressurizing, remove the auxiliary pressurizing device, and fix the restraint belt again. Specifically, allow the oil stored in the pressurizing system to enter the auxiliary pressurizing device, and slowly move the first hydraulic rod 12 of the auxiliary pressurizing device downward to make the mandibular support 13 fit closely with the mandible. At this time, record the scale of the marker ball 17, and use the pressurizing device to assist in adding force. Move both hands according to the temporomandibular joint reduction technique to reset the dislocated temporomandibular joint. During this process, always pay attention to the position of the marker ball 17 to prevent violent operation. After the reduction is successful, fix the restraint belt with appropriate force, slowly remove the auxiliary device, and adjust the restraint belt again to complete the reduction and fixation of the dislocated temporomandibular joint.

[0059] The following two embodiments will be used to illustrate how the present invention performs the work of resetting the temporomandibular joint by human power and electric pressure.

[0060] Embodiment 1

[0061] Structure Fig.10 As shown, the pressurizing system in this embodiment includes an oil reservoir 24, a pressurizing device and a valve switch 18, the two ends of the oil reservoir 24 are respectively connected to the pressurizing device and the valve switch 18, the pressurizing device is a foot-operated structure, including: a reboundable plastic barrel 20, a second hydraulic rod 21, a second spring 19 and a foot-operated plate, the bottom of the reboundable plastic barrel 20 is fully open, the second spring 19 and the second hydraulic rod 21 are arranged in the reboundable plastic barrel 20, the upper end of the second hydraulic rod 21 extends out of the upper end of the reboundable plastic barrel 20 and is connected to the foot-operated plate, the two ends of the bottom of the reboundable plastic barrel 20 are respectively connected to the oil reservoir 24 and the auxiliary pressurizing device through pipelines, a second one-way valve 23 is arranged between the reboundable plastic barrel 20 and the oil reservoir 24, and a first one-way valve 22 is arranged between the reboundable plastic barrel 20 and the auxiliary pressurizing device.

[0062] When using: First, place the restraint belt in Figure 1As shown, it is fixed on the patient's face. There is no need to fix it with force at this time. Then insert the fixing wing 5 of the top cap 3 into the belt pocket of the restraint belt or use a zipper to connect and fix the top cap 3. After the auxiliary pressure device is tightly fitted to the upper jaw through the maxillary support 8, connect the connecting rod 6 and adjust the length and distance so that the top cap 3 and the auxiliary pressure device are installed stably. Next, by stepping on the foot pedal downward, the resilient plastic barrel 20 is compressed downward after being subjected to the downward force, and the hydraulic oil at the bottom of the compression barrel rushes open the first one-way valve 22, so that the oil at the lower end of the resilient plastic barrel 20 enters the auxiliary pressurizing device in one direction, and the foot pedal is continuously pressed. During the stepping process, when the foot pedal drives the second hydraulic rod 21 to rise under the action of the second spring 19, the first one-way valve 22 is closed and the second one-way valve 23 is opened. At this time, the oil in the oil reservoir 24 is transported to the lower end of the resilient plastic barrel 20, and when the foot pedal moves downward, the second one-way valve 23 is closed and the first one-way valve 22 is opened, that is, in the process of continuously stepping on the foot pedal, continuous rehydration is achieved, and a steady stream of oil is transported to the hydraulic device in the auxiliary pressurizing device through the pipeline. After the first hydraulic rod 12 in the hydraulic device is slowly moved downward to make the mandibular support 13 fit closely with the mandibular support, the scale of the marking ball 17 is recorded at this time. When the predetermined scale is reached, the force is stopped, and both hands are moved according to the temporomandibular joint reduction technique to reduce the dislocated temporomandibular joint. After the temporomandibular joint is reduced and fixed, the valve switch 18 is stepped down, and the oil in the hydraulic device is discharged into the oil reservoir 24 along the metal pipe 9 and the pipeline. The restraint belt is appropriately fixed with force, and the auxiliary pressure device is slowly removed, and the restraint belt is adjusted again to complete the reduction and fixation of the dislocated temporomandibular joint.
