Description

Technical Field

[0001] The present invention relates to the technical field of surgical auxiliary equipment, and in particular to a covering device for oral and maxillofacial surgery. Background Art

[0002] Oral and maxillofacial surgery covers a wide range, mainly including tooth and periodontal tissue surgery, jaw surgery, oral soft tissue surgery and facial nerve surgery. During oral and maxillofacial surgery, in order to maintain the sterility of the surgical site and avoid unnecessary infection, the patient's face needs to be covered to ensure the safety of the operation.

[0003] In existing oral and maxillofacial surgery techniques, doctors usually cover the patient's face with a sterile cloth and use the pre-opened opening on the sterile cloth to align with the oral and maxillofacial surgery area, thereby exposing the oral and maxillofacial surgery area for surgery. If the size of the opening needs to be adjusted, the doctor needs to trim the opening with scissors to make the opening fit the size of the oral and maxillofacial surgery area, which is inefficient and inconvenient.

[0004] In summary, how to solve the problem in existing oral and maxillofacial surgery techniques that it is difficult to quickly and conveniently adjust the size of the covering range according to the patient's facial condition has become a difficult problem that needs to be solved in the current art. Therefore, it is necessary to propose a convenient covering device for oral and maxillofacial surgery. Summary of the invention

[0005] To solve the above problems, the present invention provides a covering device for oral and maxillofacial surgery. Through the design of the extension plate and the covering cloth, the size of the covering cloth can be quickly adjusted according to the size of the oral and maxillofacial surgery area, thereby effectively improving the convenience and efficiency of the surgery.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a covering device for oral and maxillofacial surgery, comprising an annular base plate and a plurality of center rods, the center rods all penetrate the base plate and rotatably cooperate with the base plate, the bottom of the center rods are fixedly connected with an arc-shaped extension plate, the top of the center rods are fixedly provided with a first gear, a gear ring is rotatably cooperated with the base plate, and the first gear is meshed with the gear ring; an annular and elastic covering cloth is detachably provided on the base plate, and the extension plates are slidably cooperated with the inner wall of the covering cloth.

[0007] A driving assembly for driving the gear ring to rotate and thus adjust the covering range is provided on one side of the bottom plate; a supporting assembly for supporting the bottom plate and an adjusting assembly for adjusting the position of the bottom plate are also provided on the bottom plate.

[0008] The technical principles of the above scheme are as follows:

[0009] Since the cover cloth is ring-shaped, the middle part of it can constitute the surgical window for oral and maxillofacial surgery; the driving component drives the gear ring to rotate, and since the gear ring is meshed with the first gear, the gear ring drives the first gear to rotate, and since the first gear is fixed to the extension plate through the center rod, and the center rod rotates with the bottom plate, the first gear drives the extension plates to rotate together, and all the extension plates move closer to each other toward the middle of the bottom plate; since the cover cloth has good elasticity, and the extension plates are slidably matched with the inner wall of the cover cloth, the extension plates will stretch the cover cloth, thereby reducing the surgical window and increasing the covered area; conversely, the surgical window can be enlarged and the covered area can be reduced; and the position of the cover cloth can be adjusted by adjusting the component so that the surgical window is aligned with the patient's surgical area.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The present invention can quickly and conveniently adjust the covering range of the covering cloth and the size of the surgical window through the design of the extension plate and the covering cloth; compared with the prior art method of cutting sterile cloth, the present invention does not require the doctor to cut, and only needs to adjust the rotation angle of the first gear to adjust the angle and extension distance of the extension plate, thereby stretching the elastic covering cloth to achieve the regulation of the covering range and the adjustment of the size of the surgical window. The operation is simple, and it can achieve adjustment of different size ranges, can adapt to patients with different facial conditions, and effectively improve the convenience and efficiency of the operation.

[0012] 2. The present invention uses a sterile covering cloth to wrap each component, which can effectively avoid the influence of other components on the sterile conditions and improve the quality of the surgical environment. The covering cloth and the base plate are designed to be detachable, so the covering cloth can be removed, cleaned or quickly replaced after each operation. At the same time, it is also convenient to disinfect the internal components, thereby further ensuring the sterility requirements of the operation.

[0013] 3. The present invention can effectively adjust the covering position according to the patient's facial condition and surgical requirements through the design of the adjustment component, so that the surgical window is aligned with the patient's surgical area, thereby facilitating the doctor to perform the operation better and effectively improving the overall rationality and practicality of the device.

[0014] Furthermore, the driving assembly includes a controller and a mounting plate fixedly connected to one side of the base plate, a double-headed driving member is embedded and installed on the mounting plate, an eccentric rod is coaxially fixedly connected to the output shaft at one end of the double-headed driving member, a sliding rod is fixedly connected to the top of the eccentric rod away from one end of the double-headed driving member; a sliding rail for the sliding rod to move is fixedly connected to one side of the gear ring; the controller is used to control the operation of the double-headed driving member, thereby driving the eccentric rod to rotate.

[0015] Beneficial effect: the double-headed driving member is started by the controller, and the top output shaft of the double-headed driving member drives the eccentric rod to rotate, and then drives the sliding rod to rotate, and the sliding rod will push the slide rail to swing back and forth. Since the bottom plate and the gear ring rotate in coordination, the slide rail will drive the gear ring to rotate back and forth on the bottom plate, and then drive the first gear to rotate back and forth. When the first gear rotates clockwise, the center rod also rotates clockwise, driving the extension plate to rotate clockwise, so that all the extension plates move closer to each other toward the middle of the bottom plate, and then pull the cover cloth to extend, expand the covering area, and reduce the operating window; similarly, when the first gear rotates counterclockwise, the extension plate will also rotate counterclockwise, so that all the extension plates move closer to the edge of the bottom plate, and then the cover cloth will shrink through its own elastic force, reduce the covering area, and expand the operating window.

[0016] Furthermore, the support assembly includes a support frame and a limit block fixedly connected to the bottom of the mounting plate, the support frame is provided with a sliding groove for the mounting plate and the slide rail to slide; the bottom wall of the sliding groove is provided with a limit groove for the limit block to slide; and movable components for adjusting the position of the support frame are provided at both ends of the support frame.

[0017] Beneficial effects: The support frame can provide support for the entire device and improve the overall stability of the device; the sliding groove can provide a limit for the mounting plate and the slide rail to prevent the mounting plate and the slide rail from shaking up and down; through the design of the limit block and the limit groove, the mounting plate can be further limited and fixed to prevent the mounting plate from shaking back and forth and prevent the mounting plate from slipping out of the sliding groove, thereby greatly improving the overall stability of the device.

[0018] Furthermore, the adjustment component includes a toothed plate fixedly connected to the inner wall of the sliding groove; the output shaft of the double-headed driving member at one end away from the eccentric rod is coaxially fixedly connected to the second gear; the second gear is meshed with the toothed plate; the controller is used to control the operation of the double-headed driving member, thereby driving the second gear to rotate.

[0019] Beneficial effect: When the double-head drive component is started, the output shaft at its bottom will drive the second gear to rotate. Since the second gear is meshed with the tooth plate, the mounting plate and the sliding groove slide together; the limit block and the limit groove slide together, so the cover cloth will move along the length direction of the support frame, thereby realizing the adjustment of the covering position and the position of the surgical window.

[0020] Furthermore, the moving assembly includes a moving vehicle slidably connected to the side wall of the support frame, and the controller is used to control the operation of the moving vehicle to adjust the covering position.

[0021] Beneficial effects: The mobile cart is placed on the ground, and the movement of the mobile cart is controlled by the controller, thereby effectively adjusting the position of the entire device; combined with the rotation of the second gear, the doctor can adjust the cover cloth to any position above the bed, effectively improving the comprehensiveness and convenience of the cover. The mobile cart is placed on the ground to enable better movement, and at the same time, the device does not occupy the space of the bed, improving the doctor's operability and the patient's comfort.

[0022] Furthermore, a medical drape is fixedly mounted on the edge of the covering cloth.

[0023] Beneficial effects: The design of the medical drape can cover the patient's face in a three-dimensional manner, exposing only the surgical area of ​​the patient's face, thereby effectively improving the covering effect.

[0024] Furthermore, a fixed sleeve at the bottom of the medical drape is provided with an annular water pipe, and sterile water is stored in the water pipe.

[0025] Beneficial effect: The design of the water pipe can make the bottom of the medical drape drape, so that the edge of the medical drape can drape well around the patient's face, improve the shielding effect, and avoid the medical drape from shifting or floating during the operation.

[0026] Furthermore, a heating plate is fixedly connected in the water pipe, and the controller is used to adjust the heating temperature of the heating plate.

[0027] Beneficial effect: When the patient's skin is exposed for a long time and feels cold, the heating temperature of the heating plate can be adjusted through the controller to heat the sterile water in the water pipe, thereby keeping the patient warm.

[0028] Furthermore, a lighting lamp is fixedly connected to the bottom of the extension plate, and the controller is used to control the on and off of the lighting lamp.

[0029] Beneficial effect: By turning on the lighting lamp through the controller, the light will illuminate the patient's surgical position through the cover cloth, thereby providing a good lighting environment for the doctor.

[0030] Furthermore, the slide bar is a telescopic bar, and the controller is used to control the extension and retraction of the slide bar.

[0031] Beneficial effect: When the size of the covering cloth has been adjusted, but the position of the covering cloth needs to be adjusted, the sliding rod can be retracted through the controller to make the sliding rod disengage from the sliding rail, so that the sliding rod cannot drive the sliding rail to move, so that when the position of the covering cloth is adjusted, the size of the covering cloth will not change, so that it can be adjusted more accurately.

[0032] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Embodiment 1:

[0040] like Figure 1-Figure 4 As shown, a covering device for oral and maxillofacial surgery includes an annular base plate 1 and a plurality of center rods 2. The center rods 2 all penetrate the base plate 1 and rotatably cooperate with the base plate 1. An arc-shaped extension plate 3 is welded to the bottom of the center rods 2. A first gear 4 is bolted and sleeved on the top of the center rods 2. A gear ring 5 is rotatably cooperated on the base plate 1, and the first gear 4 is meshed with the gear ring 5.

[0041] The bottom plate 1 is covered with a ring-shaped elastic covering cloth 12 by means of medical adhesive tape or needle. In this embodiment, medical adhesive tape is used to install the covering cloth 12. The extension plates 3 are all slidably matched with the inner wall of the covering cloth 12.

[0042] A driving assembly for driving the gear ring 5 to rotate and adjust the covering range is provided on one side of the bottom plate 1 ; a supporting assembly for supporting the bottom plate 1 and an adjusting assembly for adjusting the position of the bottom plate 1 are also provided on the bottom plate 1 .

[0043] like Figure 2As shown, the driving assembly includes a controller and a mounting plate 101 welded to one side of the bottom plate 1, a double-headed driving member is embedded and mounted on the mounting plate 101, the upper output shaft of the double-headed driving member is coaxially bolted and fixedly connected to the eccentric rod 6, and the top of the other end of the eccentric rod 6 is bolted and fixedly connected to the slide bar 601; one side of the gear ring 5 is bolted and fixedly connected to the slide rail 501 for the slide bar 601 to move; the controller is used to control the operation of the double-headed driving member, thereby driving the eccentric rod 6 to rotate. In this embodiment, the double-headed driving member uses a double-headed motor.

[0044] like Figure 1 and Figure 2 As shown, the support assembly includes a support frame 9 and a limit block 8 welded to the bottom of the mounting plate 101, and a sliding groove is opened on the support frame 9 for the mounting plate 101 and the slide rail 501 to slide; a limit groove is opened on the bottom wall of the sliding groove for the limit block 8 to slide; and moving components for adjusting the position of the support frame 9 are provided at both ends of the support frame 9.

[0045] The support frame 9 can provide support for the entire device and improve the overall stability of the device; the sliding groove can provide a limit for the mounting plate 101 and the slide rail 501 to prevent the mounting plate 101 and the slide rail 501 from shaking up and down; through the design of the limit block 8 and the limit groove, the mounting plate 101 can be further limited and fixed to prevent the mounting plate 101 from shaking back and forth and prevent the mounting plate 101 from slipping out of the sliding groove, thereby greatly improving the overall stability of the device.

[0046] like Figure 1 and Figure 2 As shown, the adjustment assembly includes a toothed plate 10 fixedly connected to the inner wall of the sliding groove by bolts; the output shaft at the lower end of the double-headed motor is coaxially fixedly connected with a second gear 7 by bolts; the second gear 7 is meshed with the toothed plate 10; and the controller is used to control the operation of the double-headed motor, thereby driving the second gear 7 to rotate.

[0047] The moving assembly includes a moving vehicle 11 slidably connected to the side wall of the support frame 9, and the controller is used to control the movement of the moving vehicle 11 to adjust the covering position. Figure 1 As shown, in this embodiment, remote control wheels are embedded and installed on both sides of the support frame 9, and the controller is used to control the operation of the remote control wheels; the side walls of the mobile vehicle 11 are provided with rolling grooves for the sliding of the remote control wheels. During the operation, the doctor can control the rolling of the remote control wheels through the controller, thereby driving the support frame 9 to move forward and backward along the bed, and then finely adjust the covering position.

[0048] The specific implementation process is as follows:

[0049] by Figure 1For example, before the operation, the doctor places the aseptically treated mobile cart 11 on the ground, and controls the mobile cart 11 to move along the length of the bed through the controller, thereby driving the support frame 9 and the cover cloth 12 to move, and adjusting the position of the cover cloth 12 along the length of the bed so that the cover cloth 12 is located near the patient's face. Placing the mobile cart 11 on the ground can better move, and at the same time, the device does not occupy the space of the bed, thereby improving the doctor's operability and the patient's comfort.

[0050] In this embodiment, the mobile vehicle 11 has a telescopic function, which is essentially to adjust the height of the support frame 9, such as JLG600S, GenieS-60 and HaulotteHT28RTJ, which is a part of the prior art and will not be described in detail in this embodiment, so that it can adapt to beds of different heights and patients of different statures. The mobile vehicle 11 also has a locking function, which is essentially to fix the entire device, such as TRX-6, which is a part of the prior art and will not be described in detail in this embodiment. When the doctor needs the entire device to be fixed, the mobile vehicle 11 can be locked through the controller to ensure overall stability.

[0051] like Figure 3 As shown, since the cover cloth 12 is annular, the middle part thereof can constitute a surgical window for oral and maxillofacial surgery to expose the surgical area, and the remaining part can cover the non-surgical area.

[0052] by Figure 2 For example, after the position adjustment of the cover cloth 12 along the length direction of the bed is completed, the doctor can further adjust the position of the cover cloth 12 along the width direction of the bed so that the surgical window is aligned with the patient's surgical area. In this process, the doctor starts the double-headed motor through the controller, and the output shaft at the lower end of the double-headed motor drives the second gear 7 to rotate. Since the second gear 7 is meshed with the tooth plate 10, the mounting plate 101 slides with the sliding groove; the limit block 8 slides with the limit groove, so the mounting plate 101 will slide along the sliding groove, thereby driving the cover cloth 12 to move along the length direction of the support frame 9, thereby adjusting the covering position and the position of the surgical window so that the surgical window is facing the patient's surgical area.

[0053] During this process, the output shaft at the top of the double-headed motor will drive the eccentric rod 6 to rotate, and then drive the slide bar 601 to rotate, and the slide bar 601 will push the slide rail 501 to swing back and forth. Since the bottom plate 1 and the gear ring 5 rotate in coordination, the slide rail 501 will drive the gear ring 5 to rotate back and forth on the bottom plate 1, and then drive the first gear 4 to rotate back and forth. When the first gear 4 rotates clockwise, the center rod 2 also rotates clockwise, driving the extension plate 3 to rotate clockwise, so that all the extension plates 3 move closer to each other toward the middle of the bottom plate 1, and then pull the cover cloth 12 to extend, expand the covering area, and reduce the surgical window; similarly, when the first gear 4 rotates counterclockwise, the extension plate 3 will also rotate counterclockwise, so that all the extension plates 3 move closer to the edge of the bottom plate 1, and then the cover cloth 12 will shrink through its own elastic force, reduce the covering area, and expand the surgical window.

[0054] Through the design of the double-headed motor, the doctor can adjust the size of the cover cloth 12 while adjusting the position of the cover cloth 12, which effectively improves the convenience of adjusting the cover cloth 12 and the efficiency of the operation.

[0055] Through the design of the extension plate 3 and the covering cloth 12, the covering range of the covering cloth 12 and the size of the surgical window can be adjusted quickly and conveniently; compared with the prior art, in which adjustment is performed by cutting sterile cloth, the present invention does not require the doctor to cut, and only needs to adjust the rotation angle of the first gear 4 to adjust the angle and extension distance of the extension plate 3, thereby stretching the elastic covering cloth 12 to achieve the regulation of the covering range and the adjustment of the size of the surgical window. The operation is simple, and adjustment of different size ranges can be achieved, which can adapt to patients with different facial conditions and effectively improve the convenience and efficiency of the operation.

[0056] Wrapping each component with a sterile covering cloth 12 can effectively prevent the influence of other components on the sterile conditions and improve the quality of the surgical environment. The covering cloth 12 and the base plate 1 are designed to be detachable, so the covering cloth 12 can be removed, cleaned or quickly replaced after each operation. It is also convenient to disinfect the various components inside the covering cloth 12, thereby further ensuring the sterility requirements of the operation.

[0057] Through the design of the second gear 7, the tooth plate 10 and the mobile vehicle 11, the doctor can adjust the cover cloth 12 to any position above the bed, so that the doctor can effectively adjust the position of the cover according to the patient's facial condition and the surgical position, ensuring that the surgical window is aligned with the patient's surgical area, thereby facilitating the doctor to better perform the operation and effectively improving the overall comprehensiveness and convenience of the device.

[0058] Embodiment 2:

[0059] like Figure 3-Figure 4As shown, the difference from the above embodiment is that a medical drape 13 is fixedly bonded to the edge of the covering cloth 12 .

[0060] The specific implementation process is as follows: During the operation, the medical drape 13 can cover the patient's face in a three-dimensional manner, exposing only the surgical area of ​​the patient's face, thereby effectively improving the covering effect.

[0061] Embodiment 3:

[0062] like Figure 4 As shown, the difference from the above embodiment is that a ring-shaped water pipe 14 is fixedly bonded to the bottom of the medical drape 13, and sterile water is stored in the water pipe 14.

[0063] The specific implementation process is as follows: during the operation, due to the gravity effect of the water pipe 14, the water pipe 14 can make the bottom of the medical drape 13 have good drape, so that the edge of the medical drape 13 can drape around the patient's face, thereby improving the shielding effect and avoiding the medical drape 13 from deflecting or floating during the operation.

[0064] Embodiment 4:

[0065] like Figure 4 As shown, the difference from the above embodiment is that a heating plate is fixedly bonded inside the water pipe 14, and the controller is used to adjust the heating temperature of the heating plate.

[0066] The specific implementation process is as follows: during the operation, when the patient's skin is exposed for a long time and feels cold, the heating temperature of the heating plate can be adjusted by the controller to heat the sterile water in the water pipe 14, thereby keeping the patient warm.

[0067] Embodiment 5:

[0068] like Figure 1 and Figure 2 As shown, the difference from the above embodiment is that the bottom of the extension plate 3 is fixedly connected with a lighting lamp by bolts, and the controller is used to control the opening and closing of the lighting lamp.

[0069] The specific implementation process is as follows: During the operation, the doctor can turn on the lighting through the controller, and the light will illuminate the patient's surgical position through the cover cloth 12, thereby providing a good lighting environment for the doctor.

[0070] Embodiment 6:

[0071] like Figure 2 As shown, the difference from the above embodiment is that the slide bar 601 is a telescopic rod, and the controller is used to control the extension and retraction of the slide bar 601.

[0072] The specific implementation process is as follows: during the operation, when the size of the covering cloth 12 has been adjusted, but the position of the covering cloth 12 needs to be adjusted, the doctor can retract the output end of the slide bar 601 through the controller to disengage it from the slide rail 501, thereby making it impossible for the slide bar 601 to drive the slide rail 501 to move, so that when the position of the covering cloth 12 is adjusted, the size of the covering cloth 12 will not change, so that it can be adjusted more accurately, thereby improving the accuracy of the operation.

[0073] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
