Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an oral retractor for use in oral surgery. Background Technology

[0002] Oral surgery studies diseases affecting oral organs, including the lips, tongue, palate, pharynx, facial skin and soft tissues, facial bones such as the maxilla, mandible, and zygomatic bone, temporomandibular joint, salivary glands, and neck. Oral surgery can treat infections, trauma, tumors, and other conditions.

[0003] In existing technologies, the expansion and contraction characteristics of the fixation capsule facilitate its placement in the mouth for examination and treatment without causing damage to the oral cavity. It also facilitates observation and use when used with a camera. The auxiliary device allows for adjustable inflation and rapid deflation to adapt to the oral cavity and handle emergencies. However, there is no fixed structure within the operating opening during use. As the fixation capsule expands during inflation, it compresses the operating opening, causing it to shrink and making surgery difficult for the dentist. For example, the oral fixation device for dentistry provided in patent announcement number CN109363616B involves placing the fixation capsule in the patient's mouth and adjusting the position of the operating opening by rotating the capsule. Position the operating port so that it aligns with the area inside the mouth requiring examination or treatment. Then, continuously compress the inflatable balloon, which inflates the fixation balloon through the air tube. Observe the expansion of the fixation balloon; stop compressing when the balloon is just inflated. The balloon can then be expanded to adapt to the oral cavity. Treatment and examination can then be performed through the operating port. The inflation of the balloon can be controlled, allowing it to adapt to different oral cavity sizes. The fixation balloon is comfortable and adapts to the size of the mouth. The outer surface of the fixation balloon is made of elastic material, which can be adjusted to better fit the size of the mouth without causing secondary damage. A camera at the lower end of the operating port transmits images of the area to an external display for easy observation and treatment.

[0004] It has significant drawbacks: there is no fixed structure inside the operating port during use. When the fixation bladder is inflated, the expansion of the fixation bladder will compress the operating port, causing the operating port to become smaller and smaller, making it inconvenient for doctors to perform surgery. Summary of the Invention

[0005] This application provides an oral retractor for oral surgery, which solves the problem in the prior art where there is no fixed structure inside the operating mouth. During use, the expansion of the fixation bladder compresses the operating mouth, causing it to shrink continuously and making it inconvenient for the doctor to perform surgery. The retractor opens the opening by pulling with a traction rope, preventing it from closing. At the same time, the outer wall of the fixation cylinder fits against the inner wall of the patient's oral cavity, and the opening can pull the patient's oral cavity open when it is opened, making it easier for the doctor to perform surgery inside the patient's oral cavity.

[0026] The external support cylinder is made of medical-grade silicone.

[0027] The external support cylinder divides the cavity of the fixed cylinder sidewall into two separate chambers, and the cavity between the outer wall of the external support cylinder and the sidewall of the fixed cylinder is filled with paraffin wax.

[0049] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0050] Firstly, it effectively prevents the opening from being squeezed by the side of the fixation tube due to inflation and expansion, which would make the opening smaller and thus make it inconvenient to perform surgery. At the same time, the opening is opened by pulling the traction rope, and the outer wall of the fixation tube fits against the inner wall of the patient's mouth, which can pull the patient's mouth open, making it easier for doctors to perform surgery inside the patient's mouth.

[0051] Secondly, the shape of the fixed cylinder can be shaped by the paraffin wax between the external support cylinder and the fixed cylinder, so that it has a certain supporting effect, which can support the patient's oral cavity, making it easier and more stable to use, and improving the patient's comfort.

[0052] Third, the paraffin wax between the external support tube and the fixation tube, as well as the paraffin wax inside the internal support tube, hardens together, improving the support effect on the patient's oral cavity and increasing the strength. At the same time, due to the expulsion of internal gas from the fixation tube, the thickness of the fixation tube decreases, thereby reducing the thickness of the opening. Meanwhile, the diameter of the coaxial cavity of the fixation tube increases, facilitating the surgery.

[0053] Fourth, the camera's tilt angle can be adjusted depending on the location of the opening, making it easier to observe the opening, facilitating surgery, and improving the success rate of the surgery. Attached Figure Description

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0065] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0067] During surgery inside a patient's mouth, a fixation tube 110 is placed inside the patient's mouth with the opening 112 facing the area to be operated on. The fixation tube 110 is inflated by an air pump 150. As the fixation tube 110 inflates, the ends of the traction rope 130 pull on the fixation rods 140 on both sides of the opening 112, causing the opening 112 to open. When the outer wall of the fixation tube 110 is in contact with the inner wall of the patient's mouth, inflation stops. The doctor's medical instruments can then be used to perform surgery through the coaxial cavity of the fixation tube 110 and the opening 112 into the patient's cavity. After the surgery is completed, the air pump 150 is used to deflate the fixation tube 110, and the fixation tube 110 is removed from the patient's mouth.

[0068] Example 1

[0069] like Figure 1-3As shown, this application discloses an oral retractor for oral surgery, comprising a fixing component 100, which includes a fixing cylinder 110 and an opening 112.

[0070] The fixing cylinder 110 is a cylindrical shape with a coaxial cavity, and the fixing cylinder 110 is made of medical-grade silicone.

[0071] The side wall of the fixed cylinder 110 is hollow and has a cavity structure. The cavity of the side wall of the fixed cylinder 110 is a cylinder with a coaxial cavity.

[0072] The inner ring of the fixed cylinder 110 has an initial state of hardness, and the initial axial length of the fixed cylinder 110 is 4-10 cm.

[0073] The side wall of the fixed cylinder 110 has an opening 112, the length direction of the opening 112 is parallel to the axial direction of the fixed cylinder 110, and the opening 112 is initially in a closed state.

[0074] The opening 112 passes through the side wall cavity of the fixed cylinder 110 and communicates with the coaxial cavity of the fixed cylinder 110;

[0075] The elastic coefficients at both ends of the fixed cylinder 110 along the axial direction are less than the elastic coefficients of the outer ring of the fixed cylinder 110 and the inner ring of the coaxial cavity.

[0076] The fixing component 100 also includes a groove 111, a traction rope 130, and a fixing rod 140;

[0077] The fixed cylinder 110 has a groove 111, which is an annular groove. The axis of the groove 111 is on the same straight line as the axis of the fixed cylinder 110. There are three grooves 111, which are located at the middle of the opening 112 and at both ends of the length direction, respectively.

[0078] There are two fixing rods 140. The length direction of the fixing rods 140 is parallel to the length direction of the opening 112. The fixing rods 140 are fixed on both sides inside the opening 112. The fixing rods 140 are made of medical silicone.

[0079] There are three traction ropes 130, each corresponding to a groove 111. The length of each traction rope 130 is the same as the circumference of the groove 111. Each traction rope 130 is located inside the groove 111, and both ends of each traction rope 130 are fixed to the fixing rods 140 on both sides of the opening 112.

[0080] The traction rope 130 is used to pull the opening 112, causing the opening 112 to open.

[0081] The fixed assembly 100 also includes a camera 120, an air pump 150, and an air inlet pipe 160;

[0082] The camera 120 is located in the coaxial cavity of the fixed cylinder 110, and the camera 120 faces the opening 112;

[0083] The air intake pipe 160 is fixed to one side of the fixed cylinder 110, and the air intake pipe 160 communicates with the interior of the cavity on the side wall of the fixed cylinder 110.

[0084] The output end of the air pump 150 is detachably connected to the air inlet pipe 160;

[0085] When the fixed cylinder 110 is inflated, the two ends of the traction rope 130 pull the fixed rods 140 on both sides of the opening 112, causing the opening 112 to open.

[0086] During surgery inside a patient's mouth, a fixation tube 110 is placed inside the patient's mouth with the opening 112 facing the area to be operated on. The fixation tube 110 is inflated by an air pump 150. As the fixation tube 110 inflates, the ends of the traction rope 130 pull on the fixation rods 140 on both sides of the opening 112, causing the opening 112 to open. When the outer wall of the fixation tube 110 is in contact with the inner wall of the patient's mouth, inflation stops. The doctor's medical instruments can then be used to perform surgery through the coaxial cavity of the fixation tube 110 and the opening 112 into the patient's cavity. After the surgery is completed, the air pump 150 is used to deflate the fixation tube 110, and the fixation tube 110 is removed from the patient's mouth.

[0087] Compared with existing technologies, this method effectively prevents the side of the fixation cylinder 110 from squeezing the opening 112 due to the inflation and expansion of the fixation cylinder 110, which would make the opening 112 smaller and thus make it inconvenient to perform surgery. At the same time, the opening 112 is opened by the pulling of the traction rope 130, and the outer wall of the fixation cylinder 110 fits against the inner wall of the patient's oral cavity, which can pull the patient's oral cavity open, making it easier for doctors to perform surgery inside the patient's oral cavity.

[0088] Example 2

[0089] In the first embodiment, the fixing cylinder 110 supports the patient's oral cavity. When the fixing cylinder 110 is inside the patient's oral cavity, the patient's prolonged open-mouth posture causes discomfort. Furthermore, the patient needs to exert continuous force to prevent compression of the fixing cylinder 110, leading to deformation. The patient's continuous pressure also alters the shape of the opening 112, increasing the difficulty of the procedure. Therefore, the solution in the first embodiment is improved, such as... Figures 4-5 As shown:

[0090] It also includes a support assembly 200, which includes an outer support cylinder 210 and a temperature controller 220;

[0091] The external support cylinder 210 is a cylinder with a coaxial cavity. The axis of the external support cylinder 210 is on the same straight line as the axis of the fixed cylinder 110. The external support cylinder 210 is located in the cavity of the side wall of the fixed cylinder 110. The length of the external support cylinder 210 is the same as the length of the cavity of the side wall of the fixed cylinder 110. The two ends of the external support cylinder 210 in the axial direction are fixed to the two ends of the cavity of the side wall of the fixed cylinder 110 in the axial direction.

[0092] The external support cylinder 210 is made of medical-grade silicone.

[0093] The external support cylinder 210 divides the cavity of the side wall of the fixed cylinder 110 into two separate chambers. The cavity between the outer wall of the external support cylinder 210 and the side wall of the fixed cylinder 110 is filled with paraffin wax, the melting point of which is 50 degrees Celsius.

[0094] The temperature controller 220 is fixed to the outer wall of the outer support cylinder 210. There are ten to twenty temperature controllers 220, which are evenly spaced.

[0095] The temperature controller 220 internally includes an electric heating element and a semiconductor cooling element;

[0096] The temperature controller 220 is used to control the form of paraffin wax between the outer wall of the outer support cylinder 210 and the side wall of the fixed cylinder 110.

[0097] The chamber formed between the inner ring of the outer support cylinder 210 and the side wall cavity of the fixed cylinder 110 is connected to the air inlet pipe 160.

[0098] The opening 112 passes through the outer support cylinder 210 and communicates with the coaxial cavity of the fixed cylinder 110.

[0099] During use, the paraffin wax between the external support cylinder 210 and the fixed cylinder 110 can be heated by the heating element inside the temperature controller 220 until it melts. After melting, the fixed cylinder 110 is inflated by the air pump 150 and expands inside the patient's mouth. After it fits against the inner wall of the patient's mouth, the shape of the paraffin wax will change according to the shape of the patient's mouth. The thermoelectric cooling element inside the temperature controller 220 cools the paraffin wax and sets its shape. After the paraffin wax is set, the thermoelectric cooling element stops working. After the operation is completed, the paraffin wax between the external support cylinder 210 and the fixed cylinder 110 is heated by the heating element inside the temperature controller 220 until it melts, and the fixed cylinder 110 is removed from the patient's mouth.

[0100] The shape of the fixed cylinder 110 can be shaped by the paraffin wax between the external support cylinder 210 and the fixed cylinder 110, so that it has a certain supporting effect. This can support the patient's oral cavity, making it easier and more stable to use, and improving the patient's comfort.

[0101] Example 3

[0102] In the second embodiment, the outer surface of the expanding fixing cylinder 110 is hardened to provide a certain supporting effect. During use, the fixing cylinder 110 is inflated, increasing its thickness and consequently the thickness of the opening 112. Simultaneously, the diameter of the coaxial cavity of the fixing cylinder 110 decreases, making surgery inconvenient. Therefore, the solution in the second embodiment is improved, such as... Figure 6 As shown:

[0103] The support assembly 200 also includes an internal support cylinder 230 and a temperature controller 240;

[0104] The internal support cylinder 230 is a cylinder with a coaxial cavity, and the sidewall of the internal support cylinder 230 is a hollow structure.

[0105] The axis of the inner support cylinder 230 is on the same straight line as the axis of the fixed cylinder 110, and the length of the inner support cylinder 230 is the same as the length of the fixed cylinder 110.

[0106] The outer ring of the internal support cylinder 230 is fixed to the inner ring of the coaxial cavity of the fixed cylinder 110;

[0107] The second temperature controller 240 is fixed inside the hollow structure of the side wall of the inner support cylinder 230. There are ten to twenty temperature controllers 240, which are evenly spaced.

[0108] The hollow structure of the side wall of the internal support cylinder 230 is filled with paraffin wax, the melting point of which is 50 degrees Celsius.

[0109] The temperature controller 240 includes an electric heating element and a semiconductor cooling element.

[0110] The temperature controller 240 is used to control the morphology of the paraffin wax inside the hollow structure of the side wall of the internal support cylinder 230.

[0111] The opening 112 passes through the hollow structure of the side wall of the inner support cylinder 230 and communicates with the coaxial cavity of the inner support cylinder 230;

[0112] The camera 120 is installed in the coaxial cavity of the internal support cylinder 230.

[0113] The paraffin wax between the outer support cylinder 210 and the fixed cylinder 110 is heated by the heating element in temperature controller 220 until it melts, then heating is stopped. Next, the paraffin wax filled in the inner support cylinder 230 is heated by the heating element in temperature controller 240 until it melts, then heating is stopped. The fixed cylinder 110 is inflated and, after being fitted to the patient's mouth, the paraffin wax between the outer support cylinder 210 and the fixed cylinder 110 is cooled by the semiconductor cooling element in temperature controller 220 to set its shape. After setting, the air is extracted from the fixed cylinder 110 by air pump 150, causing the fixed cylinder to... The diameter of the inner ring of 110 and the inner support cylinder 230 increases continuously. The thickness of the opening 112 is controlled by the amount of gas extracted. When the required thickness is reached, the paraffin in the inner support cylinder 230 is cooled by the semiconductor cooling plate in the second temperature controller 240 to cool and solidify it. After the operation is completed, the paraffin between the outer support cylinder 210 and the fixing cylinder 110 is heated by the electric heating plate in the first temperature controller 220 to melt it. Then, the paraffin filled in the inner support cylinder 230 is heated by the electric heating plate in the second temperature controller 240 to melt it. The fixing cylinder 110 is then removed from the patient's mouth.

[0114] The paraffin wax between the outer support tube 210 and the fixed tube 110, as well as the paraffin wax inside the inner support tube 230, hardens together, improving the support effect on the patient's oral cavity and increasing its strength. At the same time, due to the expulsion of internal gas from the fixed tube 110, the thickness of the fixed tube 110 decreases, thereby reducing the thickness of the opening 112. Simultaneously, the coaxial cavity diameter of the fixed tube 110 increases, facilitating surgery.

[0115] Example 4

[0116] In Embodiment 3, the internal camera 120 is used to observe the surgical portion of the oral cavity within the opening 112. However, during use, the camera 120 is fixed within the coaxial cavity of the internal support cylinder 230. If the internal support cylinder 230 deforms, the position and orientation of the camera 120 will also change. Therefore, the opening 112 may not be observable during use. Based on this, the solution in Embodiment 3 is improved, such as... Figure 7-8 As shown:

[0117] The fixing assembly 100 also includes an elastic column 170, an adjusting bladder 180, and a temperature controller 190;

[0118] One end of the elastic column 170 is fixed to the camera 120, and the other end of the elastic column 170 away from the camera 120 is detachably connected to the inner wall of the coaxial cavity of the internal support cylinder 230.

[0119] There are six adjustment bladders 180, which are combined into a ring. The ring of the six adjustment bladders 180 is fitted onto the elastic column 170, and the adjustment bladders 180 are fixed to the lower side of the camera 120.

[0120] The regulating bladder 180 is filled with an 85% ethanol solution, and the regulating bladder 180 is made of medical-grade silicone.

[0121] The number of temperature controllers 190 is the same as that of the regulating bladder 180, and they correspond one-to-one. The temperature controllers 190 are fixed inside the regulating bladder 180.

[0122] The temperature controller 3190 internally includes an electric heating element and a semiconductor cooling element;

[0123] The temperature controller 190 is used to control the expansion of the 85% ethanol solution inside the regulating bladder 180.

[0124] When in use, after the internal support cylinder 230 deforms, the temperature controller 190 in the adjustment bladder 180 at different positions can be used to heat the 85% ethanol solution in the adjustment bladder 180, causing it to expand. This causes the lower side of the adjustment bladder 180 to abut against the side wall of the coaxial cavity of the internal support cylinder 230, thereby adjusting the angle of the camera 120.

[0125] Depending on the location of the opening 112, the tilt angle of the camera 120 can be adjusted to facilitate observation of the opening 112, making surgery easier and increasing the success rate of the surgery.

[0126] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
