Description

Technical Field

[0001] The utility model relates to a maxillary sinus implantable distraction osteogenesis air bag, belonging to the technical field of distraction osteogenesis devices. Background Art

[0002] Due to congenital genetic factors or acquired environmental factors, there are more and more patients with underdeveloped maxilla. Most patients with underdeveloped maxilla are treated with maxillary distraction osteogenesis for correction. The treatment plan in the prior art is to set traction on the face to pull the maxilla outward, thereby causing the maxilla to generate an outward expansion force, thereby enabling the maxilla to shift and achieve the purpose of correction.

[0003] An external traction brace is a commonly used surgical instrument in the correction of maxillary underdevelopment. This type of distraction osteogenesis device is ugly in appearance, heavy, and requires invasive implantation. It will produce obvious scars in the later recovery process, affecting the patient's facial appearance. At the same time, patients with maxillary underdevelopment are mostly children, who are prone to movement, have poor cooperation, and have a greater risk of accidental injury.

[0004] A Chinese patent with the announcement number CN216823749U discloses a disposable sterile surgical head frame, including a mounting seat, with head positioning frames connected to both sides of the mounting seat, and multiple fixing nails are evenly arranged at the end of the head positioning frame, and a longitudinal rod is slidably inserted at one end of the mounting seat, and a traction seat is slidably connected to the lower end of the longitudinal rod, and two extension rods are slidably inserted on the traction seat, and the ends of the extension rods are connected to springs, and the springs are connected to traction hooks. Although the surgical head frame of this patent has the advantages of less trauma, large traction force and fixation, fast traction speed, and low recurrence rate compared to traditional maxillary bone cutting surgery, it still needs to cut the patient's facial skin to implant the traction hook 8 to hook the patient's maxilla, which will leave scars on the patient's face and affect the patient's facial beauty. At the same time, the child is easy to move and has poor cooperation, and there is a greater risk of accidental injury.

[0005] Therefore, a maxillary sinus implantable distraction osteogenesis airbag is needed that does not cause facial trauma, does not affect the patient's facial appearance, is light in weight, and has high safety. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4As shown in the figure, the present utility model provides a technical solution: a maxillary sinus implantable distraction osteogenesis balloon, which includes a balloon body. The shape and size of the balloon body are adapted to the inner cavity of the patient's maxillary sinus. The balloon body includes a core balloon 1 for maintaining the shape of the balloon body. The shape of the core balloon 1 is adapted to the inner cavity of the maxillary sinus. The outside of the core balloon 1 is coated with a pressurized balloon layer. The pressurized balloon layer includes a pressurized balloon A2 and a pressurized balloon B3. The pressurized balloon A2 and the pressurized balloon B3 are in a 'rich' - shaped structure, and the branch balloons of the pressurized balloon A2 and the pressurized balloon B3 are arranged in an alternating manner. The number of branch balloons of the pressurized balloon A2 and the branch balloons of the pressurized balloon B3 is more than four. In this embodiment, the core balloon 1, the pressurized balloon A2, and the pressurized balloon B3 are integrally formed. The width of the branch balloon of the pressurized balloon A2 is 0.5 - 2.5 times the width of the branch balloon of the pressurized balloon B3. One side of the bottom of the core balloon 1, the pressurized balloon A2, and the pressurized balloon B3 are respectively provided with inflation and deflation hoses 4. The inflation and deflation hoses 4 are connected to a pulse gas source through quick - connect fittings 5. In this embodiment, the quick - connect fitting 5 is a Luer fitting, and the pulse gas source is a pulse air pump. The pulse air pump includes a silent air pump 6. A single - chip microcomputer controller 7 is provided on the silent air pump 6. The air outlet of the silent air pump 6 is connected with a three - way high - pressure hose 8, and is respectively connected to the inflation and deflation hoses 4 of the core balloon 1, the pressurized balloon A2, and the pressurized balloon B3. Three - way three - position solenoid valves 9 are respectively provided on the three branch pipes of the three - way high - pressure hose 8. The three - way three - position solenoid valves 9 are electrically connected to the single - chip microcomputer controller 7, which is convenient for controlling the inflation and deflation of the core balloon 1, the pressurized balloon A2, and the pressurized balloon B3. During the process of maxillary distraction osteogenesis, the pressurized balloon A2 and the pressurized balloon B3 alternately apply pressure to the maxillary sinus bone wall. When the pressurized balloon A2 is inflated to apply pressure to the maxillary sinus bone wall, the pressurized balloon B3 is deflated. When the pressurized balloon B3 is inflated to apply pressure to the maxillary sinus bone wall, the pressurized balloon A2 is deflated. In this embodiment, the alternating frequency is once every 25 - 35 minutes, and the pressure of the balloon body on the maxillary sinus bone wall is 400 - 500 g. Such alternating pressure application not only ensures the continuous pressure on the maxillary sinus bone wall, is convenient for distraction osteogenesis, but also ensures the blood supply of the maxillary mucosa and prevents pressure damage. The core balloon 1 always remains inflated except when the patient's maxillary sinus is rinsed in the morning and evening, so as to keep the balloon body in a full shape and facilitate the uniform force on the maxillary sinus bone wall. When rinsing the patient's maxillary sinus in the morning and evening, the core balloon 1, the pressurized balloon A2, and the pressurized balloon B3 are deflated simultaneously, which is convenient for rinsing the patient's maxillary sinus.

[0025] Preferably, the pressurized balloon A2 and the pressurized balloon B3 are respectively a pink balloon and a gray balloon.

[0026] Preferably, the pressurized balloon A2 and the pressurized balloon B3 are made of an elastic biocompatible material, which is soft and anti - inflammatory, and can avoid irritating or damaging the maxillary mucosa. In this embodiment, the pressurized balloon A2 and the pressurized balloon B3 are made of medical silicone rubber, polyurethane / chitosan composite material or PHA (polyhydroxyalkanoate).

[0027] Preferably, the outer walls of the pressurized airbag A2 and the pressurized airbag B3 are provided with an anti-allergic drug sustained-release coating or a bioaffinity material coating to avoid irritation to the maxillary mucosa.

[0028] Preferably, the outer wall of the inflation and deflation hose 4 is provided with an anti-allergic drug sustained-release coating or a bioaffinity material coating, and the tube wall of the inflation and deflation hose 4 is embedded with a spiral metal wire or a tubular metal mesh to improve the pressure resistance of the inflation and deflation hose 4.

[0029] The working principle of the utility model is that when a patient with underdeveloped maxillary bone needs distraction osteogenesis of the maxillary bone, the airbag body is implanted into the maxillary sinus through the nose, and then the inflation and deflation hoses 4 on the core airbag 1, the pressurized airbag A2 and the pressurized airbag B3 are connected to the one-to-three high-pressure hose 8 of the pulse air source outlet through a quick pipe joint. The pulse air source is a pulse air pump, and the pulse air pump includes a silent air pump 6 to inflate the core airbag 1, and at the same time, the pressurized airbag A2 and the pressurized airbag B3 are pulse-charged and deflated. The core airbag 1 maintains the shape of the airbag body, and the pressurized airbag A2 and the pressurized airbag B3 alternately apply pressure to the maxillary sinus bone wall, and distraction osteogenesis of the maxillary bone can be performed. Because the patient's maxillary sinus is relatively small at the beginning, a small airbag body needs to be used for distraction osteogenesis. During the distraction osteogenesis process, the patient's maxillary sinus will gradually expand. When the patient's maxillary sinus expands to a certain extent, a larger airbag body is replaced to continue distraction osteogenesis until the patient's maxillary bone reaches the standard extent. The maxillary sinus implantable distraction osteogenesis airbag of the utility model uses an airbag body implanted in the maxillary sinus through the nose for distraction osteogenesis. The patient has no facial trauma, does not affect the facial beauty, is light in weight, and has high safety. The shape of the airbag body is maintained by the core airbag, which facilitates uniform force on the maxillary sinus bone wall. The pressurized airbag A and the pressurized airbag B are used to alternately apply pressure to the maxillary sinus bone wall, which not only ensures continuous pressure on the maxillary sinus bone wall, facilitates distraction osteogenesis, but also ensures blood supply to the maxillary mucosa and prevents pressure damage. By setting a pulse air source, it is convenient to alternately inflate and deflate the pressurized airbag A and the pressurized airbag B, and to control the pressurized airbag A and the pressurized airbag B to apply pulsed alternating pressure to the maxillary sinus bone wall.

[0030] As an alternative, the core airbag 1, the pressurized airbag A2 and the pressurized airbag B3 are fixedly connected by adhesive bonding or hot-melt welding.
