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 dental 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 typically cover the patient's face with a sterile drape and align the pre-cut opening in the drape with the surgical area, exposing the area for surgery. If the opening needs to be resized, the doctor must trim it with scissors to fit the surgical area, which is inefficient and inconvenient.

[0004] In summary, how to solve the problem of the difficulty in quickly and conveniently adjusting the size of the mask according to the patient's facial condition in existing oral and maxillofacial surgery techniques has become a difficult problem that needs to be solved in the field. Therefore, it is necessary to propose a convenient masking 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 passing through the base plate and rotatingly cooperating with it, the bottom of the center rods are fixedly connected with an arc-shaped extension plate, the top of the center rods are fixedly sleeved with a first gear, a gear ring is rotatably cooperating with the base plate, and the first gears are meshed with the gear ring; an annular and elastic covering cloth is detachably sleeved on the base plate, and the extension plates are slidingly cooperating 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 base plate; a supporting assembly for supporting the base plate and an adjusting assembly for adjusting the position of the base plate are also provided on the base plate.

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

[0009] Since the cover cloth is annular, its middle part 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 engaged with the first gear, the gear ring will drive 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 in coordination with the base plate, the first gear will drive the extension plates to rotate together, and all the extension plates will move closer to each other toward the middle of the base plate; since the cover cloth has good elasticity, and the extension plates all slide in coordination 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 increased 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 it. It 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 can achieve adjustment of different size ranges, which 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 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 position of the cover 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 drive assembly includes a controller and a mounting plate fixedly connected to one side of the base plate, a double-headed drive member is embedded and installed on the mounting plate, an output shaft at one end of the double-headed drive member is coaxially fixedly connected to an eccentric rod, and the top of the eccentric rod away from one end of the double-headed drive member is fixedly connected to a slide rod; a slide rail for the slide 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 drive member, thereby driving the eccentric rod to rotate.

[0015] Beneficial effect: The double-headed driving member is started by the controller, and the output shaft at the top 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 base plate and the gear ring rotate in coordination, the slide rail will drive the gear ring to rotate back and forth on the base 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 base 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 base plate, and then the cover cloth will shrink through its own elastic force, reducing the covering area and expanding 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 tooth plate fixedly connected to the inner side wall of the sliding groove; the output shaft of the double-headed driving member away from the eccentric rod is coaxially fixedly connected to the second gear; the second gear is engaged with the tooth plate; the controller is used to control the operation of the double-headed driving member, thereby driving the second gear to rotate.

[0019] Beneficial effects: When the double-head drive is started, the output shaft at its bottom will drive the second gear to rotate. Since the second gear is engaged with the tooth plate, the mounting plate slides with the sliding groove; the limit block slides with the limit groove, 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 controlled by a controller, effectively adjusting the position of the entire device. Combined with the rotation of the second gear, the doctor can adjust the cover to any position above the bed, effectively improving the comprehensiveness and convenience of the cover. Placing the mobile cart on the ground allows for better mobility while ensuring that the device does not occupy bed space, improving doctor operability and patient comfort.

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

[0023] Beneficial effects: The design of the medical drape can provide three-dimensional coverage for the patient's face, 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, in which sterile water is stored.

[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 deflecting or floating during the operation.

[0026] Furthermore, a heating plate is fixedly connected to 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 to cold for a long time, 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 opening and closing of the lighting lamp.

[0029] Beneficial effect: When the lighting is turned on by 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 sliding rod is a telescopic rod, and the controller is used to control the extension and retraction of the sliding rod.

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

[0032] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by 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] Example 1:

[0040] like Figures 1-4 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 rotate with it. An arc-shaped extension plate 3 is welded to the bottom of the center rods 2. The top of the center rods 2 is bolted with a first gear 4. A gear ring 5 is rotatably fitted on the base plate 1, and the first gear 4 is meshed with the gear ring 5.

[0041] The bottom plate 1 is provided with an annular 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 thereby adjust the covering range is provided on one side of the base plate 1 ; a supporting assembly for supporting the base plate 1 and an adjusting assembly for adjusting the position of the base plate 1 are also provided on the base plate 1 .

[0043] like Figure 2As shown, the drive assembly includes a controller and a mounting plate 101 welded to one side of the base plate 1. A double-headed drive member is embedded and mounted on the mounting plate 101. The output shaft at the upper end of the double-headed drive member is coaxially bolted to the eccentric rod 6. The top end of the eccentric rod 6 is bolted to a slide rod 601. A slide rail 501 for the movement of the slide rod 601 is bolted to one side of the gear ring 5. The controller controls the operation of the double-headed drive member, thereby driving the rotation of the eccentric rod 6. In this embodiment, the double-headed drive 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. The support frame 9 is provided with a sliding groove for the mounting plate 101 and the slide rail 501 to slide; the bottom wall of the sliding groove is provided with a limit groove for the limit block 8 to slide; and both ends of the support frame 9 are provided with a movable assembly for adjusting the position 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 tooth 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 to the second gear 7 by bolts; the second gear 7 is engaged with the tooth plate 10; 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 that is slidably connected to the side wall of the support frame 9. 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 back and forth along the bed, and then finely adjust the covering position.

[0048] The specific implementation process is as follows:

[0049] by Figure 1For example, before surgery, the doctor places the sterile mobile cart 11 on the ground. Using a controller, the doctor controls the mobile cart 11 to move along the length of the bed, thereby driving the support frame 9 and the drape 12 to move. The drape 12 is adjusted along the length of the bed so that it is positioned near the patient's face. Placing the mobile cart 11 on the ground allows for easier movement while minimizing the bed's space, improving the doctor's operability and the patient's comfort.

[0050] In this embodiment, the mobile cart 11 has a telescopic function, which essentially adjusts the height of the support frame 9, as seen in the JLG600S, Genie S-60, and Haulotte HT28RTJ models. This is prior art and will not be described in detail in this embodiment. This allows the mobile cart 11 to accommodate beds of varying heights and patients of varying statures. Furthermore, the mobile cart 11 has a locking function, which essentially secures the entire device, as seen in the TRX-6 models. This is prior art and will not be described in detail in this embodiment. When the doctor requires the entire device to remain stationary, the controller can lock the mobile cart 11 to ensure overall stability.

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

[0052] by Figure 2 For example, after the position of the cover cloth 12 along the length of the bed is adjusted, the doctor can further adjust the position of the cover cloth 12 along the width of the bed so that the surgical window is aligned with the patient's surgical area. During this process, the doctor starts the double-headed motor through the controller. 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 engaged with the tooth plate 10, the mounting plate 101 slides with the sliding groove; the limit block 8 slides with the limit groove, so that the mounting plate 101 will slide along the sliding groove, thereby driving the cover cloth 12 to move along the length 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 drives the eccentric rod 6 to rotate, which in turn drives the slide bar 601 to rotate. The slide bar 601 pushes the slide rail 501 to swing back and forth. Since the base plate 1 and the gear ring 5 rotate in coordination, the slide rail 501 drives the gear ring 5 to rotate back and forth on the base plate 1, which in turn drives 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 plates 3 to rotate clockwise, causing all the extension plates 3 to move closer to the middle of the base plate 1, thereby pulling the cover cloth 12 to extend, expanding the covered area and reducing the surgical window. Similarly, when the first gear 4 rotates counterclockwise, the extension plates 3 also rotate counterclockwise, causing all the extension plates 3 to move closer to the edge of the base plate 1, thereby causing the cover cloth 12 to contract due to its own elastic force, reducing the covered area and expanding 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, effectively improving 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 regulation of the covering range and 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] Using a sterile covering cloth 12 to wrap each component can effectively prevent other components from affecting the sterile conditions and improve the quality of the surgical environment; and the covering cloth 12 and the base plate 1 are designed to be detachable, so the covering cloth 12 can be disassembled, cleaned or quickly replaced after each operation; at the same time, 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 perform the surgery better and effectively improving the overall comprehensiveness and convenience of the device.

[0058] Example 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] Example 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 drapeability, 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] Example 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] Example 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] Example 6:

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

[0072] The specific implementation process is as follows: During the operation, when the size of the cover cloth 12 has been adjusted, but the position of the cover 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, and thus when the position of the cover cloth 12 is adjusted, the size of the cover 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 clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
