Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular is a new method for repairing gingival papilla defects after gingival tumor resection by simultaneous gingival papilla reconstruction. Background Art

[0002] Gingival tumors are not true tumors, but growths that originate from the periodontal membrane and gingival connective tissue. Gingival tumors often occur in the gingival papillae on the lip and cheek sides, and are most common in the bicuspid area. They mainly manifest as localized growths of gingival tissue, with lumps of varying sizes, usually round, oval or lobed. Vascular and granulomatous gingival tumors are soft, red in color, and easy to bleed; fibrous gingival tumors are tough and hard in texture, with a color similar to normal gums, and are not easy to bleed.

[0003] The treatment of gingival tumors is mainly surgical resection. The resection should reach the bone surface, including the periosteum, and a small amount of alveolar bone corresponding to the tumor should be chiseled off to reduce the recurrence rate. At the same time, in the treatment of gingival tumors, in order to completely remove the tumor tissue, it is inevitable that a certain amount of gingival tissue defects, such as gingival papillae, will be caused. For mild gingival papillae defects, special treatment is generally not required. If the defect is more serious, surgical methods such as gingival transplantation can be considered for repair. However, this method usually involves taking a small piece of gingival tissue from other parts of the mouth (such as the palate) and then transplanting it to the defect.

[0004] When performing an epulis removal surgery, usually some tools are used to open the patient's mouth, such as a mouth expander, so that the doctor can clearly see the location of the epulis, and at the same time provide the doctor with more operating space for the operation, thereby improving the efficiency of treatment. Most of the mouth expanders on the market are one-piece molded, and the specifications are relatively fixed; although these mouth expanders generally have a certain flexibility to adapt to different patients, because the mouth expander needs to play the role of opening the patient's mouth, its flexibility is limited, and it is difficult to adjust it to a large extent. For some patients who have difficulty in expanding their mouths to a large extent, it is difficult to apply it. For this reason, it is necessary to propose a new simultaneous gingival papilla reconstruction technique to repair the gingival papilla defect after the removal of the epulis, which can expand the patient's mouth as much as possible according to the tolerance of the patient's mouth, while reducing the patient's discomfort and making it as easy as possible for the doctor to operate. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a new method for repairing the gingival papilla defect after gingival tumor resection by simultaneous gingival papilla reconstruction. The present invention is simple to operate, and through the coordinated operation between the expansion component, the moving component, the first support and the second support, it can expand the patient's oral cavity as much as possible according to the tolerance of the patient's oral cavity, while reducing the patient's discomfort and making it as convenient as possible for the doctor to operate.

[0006] In order to achieve the above-mentioned objectives, the technical scheme of the present invention is as follows: a new simultaneous gingival papilla reconstruction technique for repairing gingival papilla defects after gingival tumor resection, comprising a first support, a second support and a plurality of expansion components for expanding the patient's oral cavity, the first support and the second support are both provided with a holder for fixing the expansion components at the top, the holders are both provided with a slot at the top, the holders are provided with a plurality of press-type buckles, the second support is respectively fixedly connected with a first telescopic rod and a second telescopic rod on the side close to the first support, the second support is fixedly connected with a moving component for adjusting the distance between the first support and the second support on the side close to the first support, the first telescopic rod and the second telescopic rod are fixedly connected to the first support at one end away from the second support, a fixing component is provided on the second telescopic rod, the moving component is rotatably matched with the first support at one end away from the second support, and a controller is provided inside the first support.

[0007] The principle of the basic scheme is: the two spreading components are respectively fixed on the first support and the second support through the socket and the buckle, and then the distance between the first support and the second support is adjusted by the moving component, thereby adjusting the distance between the corresponding spreading components, and then the movement of the second telescopic rod is limited by the fixing component, thereby locking the relative position of the first support and the second support.

[0008] The beneficial effects of the basic scheme are: 1. When the present invention performs an expansion operation on the patient's oral cavity, the doctor controls the movement of the mobile component and can judge the patient's tolerance to the expansion of the oral cavity in real time according to the patient's reaction, thereby ensuring that the doctor can perform the operation normally while reducing the patient's discomfort caused by the expansion of the oral cavity.

[0009] 2. The present invention uses buckles and sockets to enable the expansion component to be quickly installed and disassembled. At the same time, because the expansion component needs to be in direct contact with the patient, it will inevitably be contaminated with the patient's blood and other liquids during the operation. Based on medical safety, these expansion components that come into contact with the patient are disposable. Therefore, this detachable connection between the expansion component and the first support and the second support can not only improve medical safety, but also be able to replace new expansion components at any time according to different patients, thereby saving costs as much as possible.

[0010] 3. The design of the first telescopic rod and the second telescopic rod of the present invention can provide a certain support to the entire device without hindering the moving assembly from changing the distance between the first support and the second support, thereby improving the stability of the entire device.

[0011] 4. The design of the fixing assembly of the present invention can limit the telescopic movement of the second telescopic rod, ensuring that after the first support and the second support reach the appropriate position, they can stably remain in the current position, thereby ensuring the stability of the device.

[0012] Furthermore, the expansion components include a card block that is interference fit with the card slot, and a number of card holes corresponding to the push-type buckles are provided on both sides of the length direction of the card block. The upper end of the card block is fixedly connected to a support rod, and the end of the support rod away from the card block is fixedly connected to an arc-shaped support sleeve.

[0013] The beneficial effects of the basic solution are: the card block is fixed in the card slot through the interference fit between the card block and the card slot, so as to reduce the possibility of the card block falling off during surgery. At the same time, the design of the opening further enhances the stability of the card block and improves the safety of the operation; the design of the arc-shaped support sleeve can open the patient's mouth, making it easier for the doctor to operate during subsequent surgery.

[0014] Furthermore, the moving component includes a main body, a moving cavity is opened inside the main body, a rack, a slider and a guide rod are respectively arranged in the moving cavity from left to right, one end of the rack is close to the slider, the slider and the rack are both slidably matched with the inner wall of the moving cavity, the slider is fixedly connected to the guide rod, the guide rod extends through the main body to the first support at one end away from the rack and is rotatably connected to the first support, the connection between the guide rod and the main body is a sliding match, a driving component corresponding to the rack is rotatably connected in the moving cavity, a spiral groove is opened on the side surface of the slider, a guide block slidably matched with the groove is fixedly connected to the inner wall of the moving cavity, a first spring is sleeved on the guide rod ring, one end of the first spring is fixedly connected to the slider, and the other end of the first spring is fixedly connected to the inner wall of the main body.

[0015] The driving assembly includes a gear meshing with the rack. The gear is semicircular, and a push rod is fixedly connected to the top of the gear. A through groove for moving the push rod is opened on the surface of the main body. One end of the push rod extends through the through groove to the outside of the main body. Both ends of the connection between the gear and the push rod are rotatably matched with the inner wall of the main body.

[0016] The beneficial effects of the basic scheme are: the gear is driven to rotate through the movement of the push rod, and the gear rotation drives the rack to slide along the inner wall of the movable cavity and drives the slider and the guide rod to slide, thereby changing the distance between the first support and the second support, and then adjusting the distance between the two arc-shaped support sleeves to ensure that the arc-shaped support sleeve can open the patient's mouth to an appropriate degree; at the same time, through the spiral slide groove on the surface of the slider and the guide block matched therewith, the slider produces corresponding rotation during the sliding process; through the first spring, the speed of movement of the arc-shaped support sleeve can be slowed down to a certain extent, reducing the possibility of causing certain injuries to the patient when the arc-shaped support sleeve moves too fast due to misoperation.

[0017] Furthermore, the fixing assembly includes a locking sleeve which is arranged around the second telescopic rod and is used to limit the movement of the second telescopic rod, and the second telescopic rod is rotationally matched with the locking sleeve.

[0018] The beneficial effect of the basic solution is that the telescopic movement of the second telescopic rod is limited by rotating the locking sleeve, so that the distance between the first support and the second support can be limited, thereby ensuring the safety and stability of the device during subsequent operations.

[0019] Furthermore, a first groove and a second groove are formed on the side of the first support close to the second support, the telescopic rod is located in the first groove, a plurality of electromagnets and a plurality of second springs are fixedly connected in the first groove, the length of the second springs is greater than the length of the electromagnets, a positioning ring is provided in the first groove, the positioning ring is sleeved on the telescopic rod, the positioning ring and the telescopic rod are slidably matched, and a magnetic attraction layer is fixedly connected to the side of the positioning ring close to the electromagnet.

[0020] The beneficial effects of the basic solution are: the positioning ring is adsorbed and fixed in the first groove through the electromagnet and the magnetic attraction layer, thereby reducing the positioning ring from sliding randomly along the telescopic rod when not in use; when the positioning ring is adsorbed, the second spring will be squeezed, and then when the electromagnet is not working, the positioning ring will be popped out by the second spring to facilitate the doctor to move the positioning ring.

[0021] Furthermore, a plurality of bearings are fixedly connected in the second groove, and the bearings are rotatably connected to the guide rod. The guide rod is located at one end surface of the second groove and is fixedly connected to a plurality of blades. A signal sensor is provided in the second groove and is located in the movement trajectory of the blade.

[0022] The beneficial effects of the basic solution are: the design of the bearing prevents the first support from rotating with the guide rod to improve safety and stability; at the same time, the rotation of the guide rod drives the blade to rotate and triggers the signal sensor to provide corresponding signals for subsequent operations.

[0023] Furthermore, a straw is fixedly connected to one side of the second support away from the first support, a suction head is detachably connected to one end of the straw close to the adjacent card seat, and the other end of the straw is connected to a negative pressure machine.

[0024] The beneficial effects of the basic scheme are: through the negative pressure machine and the suction tube connected to the negative pressure machine, the blood in the patient's mouth and other alveolar bones that may be removed during the gingival tumor removal surgery are sucked away, thereby reducing the possibility of blood and alveolar bones entering the patient's esophagus and causing secondary injuries; at the same time, the adsorption effect of the negative pressure machine can create a relatively closed and pressure-stable environment, which helps to reduce the tension on the wound surface and promote the regeneration and repair of tissue cells. And through the negative pressure effect, the blood flow rate of the wound microcirculation can be increased, the microvessels can be dilated, and the local blood circulation can be improved. At the same time, it can stimulate cell mitosis and growth factor secretion, promote angiogenesis, and thus provide sufficient nutrition and oxygen for the wound, accelerating the healing process; in gingival papilla reconstruction surgery, negative pressure adsorption may help maintain the stability and accuracy of the surgical area, improve the precision of the surgical operation, thereby promoting tissue healing and reducing complications, and indirectly improving the success rate of the operation and patient satisfaction.

[0025] Furthermore, a lighting assembly is fixedly connected to the positioning ring, and the lighting assembly includes a plurality of LED lamps, and the LED lamps are connected to the controller signal.

[0026] The beneficial effect of the basic solution is that the design of the LED light can provide doctors with a better field of vision, allowing doctors to better observe the specific conditions of the patient's surgical site.

[0027] Furthermore, a position sensor is fixedly connected to the connection between the second support and the first telescopic rod, and the position sensor is connected to the controller signal.

[0028] The beneficial effect of the basic solution is that the positioning ring can be accurately moved to the corresponding position through the position sensor, so that the subsequent LED light can accurately illuminate the area where surgery is required.

[0029] Furthermore, a new method for repairing the gingival papilla defect after gingival tumor resection by simultaneous gingival papilla reconstruction includes the following steps

[0030] Step 1: Disinfection and installation: disinfect the two arc-shaped support sleeves to be used, and then insert the corresponding card blocks of the two arc-shaped support sleeves into the corresponding card slots, press the buckles, insert the buckles into the corresponding card holes, and fix the two arc-shaped support sleeves on the first support and the second support respectively;

[0031] Step 2: support and fixation: put the two arc-shaped support sleeves into the patient's mouth for preliminary support, and then push the push rod to gradually increase the distance between the two arc-shaped support sleeves to open the patient's mouth to a suitable position. After the arc-shaped support sleeves expand the patient's mouth to a suitable degree, fix the positions of the two arc-shaped support sleeves by the fixing assembly;

[0032] Step 3, positioning lighting: based on the pre-set patient information and information from the position sensor, move the positioning ring to the position corresponding to the surgical site of the patient, and illuminate the surgical site through the LED light on the positioning ring;

[0033] Step 4, negative pressure adsorption: Start the negative pressure machine and move the suction head close to the gingival tumor to absorb the liquid and other excised materials during the operation.

[0034] The beneficial effects of the basic solution are: by adjusting the distance between the first support and the second support, the distance between the two arc-shaped support sleeves can be adjusted, so that the degree of expansion can be adjusted according to the actual situation of different patients, ensuring the smooth progress of the operation while reducing the discomfort of the patient when the mouth is opened; at the same time, the location where surgery is required is illuminated with LED lights for the doctor to observe; through the negative pressure machine, some inevitable resections and blood during the operation are sucked away, reducing the possibility of these substances entering the patient's esophagus and causing secondary damage.

DETAILED DESCRIPTION

[0042] The following is further described in detail through specific implementation methods:

[0043] Embodiment 1:

[0044] Basically as attached Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Shown is a new simultaneous gingival papilla reconstruction technique for repairing gingival papilla defects after gingival tumor resection, comprising a first support 1, a second support 6 and a plurality of expansion components 3 for expanding the patient's oral cavity.

[0045] The top of the first support 1 and the second support 6 are both integrally formed with a base 2 for fixing the expansion component 3; a card slot is opened on the top of the base 2, and a number of press-type buckles 10 are bonded to the base 2; the second support 6 is screw-fixedly connected to the first support 1 on the side thereof close to the first support 1 with a first telescopic rod 5 and a second telescopic rod 26; the second support 6 is screw-fixedly connected to the side thereof close to the first support 1 with a moving component for adjusting the distance between the first support 1 and the second support 6, and the first telescopic rod 5 and the second telescopic rod 26 are screw-fixedly connected to the first support 1 at one end away from the second support 6; a fixing component is provided on the second telescopic rod 26, and the moving component is rotatably matched with the first support 1 at one end away from the second support 6; a controller is screw-fixedly connected inside the first support 1.

[0046] The support components 3 all include a card block 303 that is interference fit with the card slot; a number of card holes 304 corresponding to the push-type buckle 10 are integrally formed on both sides of the length direction of the card block 303; a support rod 302 is integrally formed on the upper end of the card block 303; and an arc-shaped support sleeve 301 is integrally formed on the end of the support rod 302 away from the card block 303.

[0047] The moving component includes a main body 8; a moving cavity is opened inside the main body 8, and a rack 18, a slider 21 and a guide rod 9 are respectively arranged in the moving cavity from left to right; the slider 21 and the rack 18 are both slidably matched with the inner wall of the moving cavity, and the slider 21 is bonded to the guide rod 9; the guide rod 9 extends through the main body 8 to the first support 1 at one end away from the slider 21 and is rotatably connected with the first support 1, and the connection between the guide rod 9 and the main body 8 is a sliding match; a driving component corresponding to the rack 18 is rotatably connected in the moving cavity, and a spiral groove 20 is opened on the side surface of the slider 21; a guide block 19 slidably matched with the groove 20 is bonded to the inner wall of the moving cavity; a first spring 22 is ringed on the guide rod 9; one end of the first spring 22 is fixedly connected to the slider 21, and the other end of the first spring 22 is fixedly connected to the inner wall of the moving cavity.

[0048] The driving assembly includes a gear 17 meshing with a rack 18; the gear 17 is semicircular, and a push rod 16 is integrally formed on the top of the gear 17; a through groove for the movement of the push rod 16 is opened on the surface of the main body 8, one end of the push rod 16 extends through the through groove to the outside of the main body 8, and both ends of the connection between the gear 17 and the push rod 16 are rotatably matched with the inner wall of the main body 8.

[0049] The fixing assembly includes a locking sleeve which is arranged around the second telescopic rod 26 and is used to limit the movement of the second telescopic rod 26 , and the second telescopic rod 26 is rotationally matched with the locking sleeve.

[0050] The specific implementation process is as follows: first, insert the two card blocks 303 into the corresponding card slots of the card holder 2 respectively. Since the card block 303 and the card slot are interference fit, the card block 303 will be initially fixed in the card slot. At the same time, in order to further fix the card block 303, press the buckle 10 on the card holder 2 to insert the buckle 10 into the corresponding card hole 304 on the card block 303, and then finally fix the card block 303, so that the one-piece card block 303, the support rod 302 and the arc-shaped support sleeve 301 are fixed on the first support 1 and the second support 6 to avoid medical accidents caused by the falling of the card block 303 during surgery and improve the stability during surgery.

[0051] At the same time, because the arc-shaped support sleeve 301 needs to be placed in the patient's mouth and cannot avoid contact with the patient's blood, based on common sense in medical safety, the arc-shaped support sleeve 301 is a disposable item and needs to be destroyed after use to avoid the risk of infectious diseases between patients due to repeated use. Therefore, the detachable connection between the block 303 and the holder 2 can facilitate the rapid installation, disassembly and replacement of the arc-shaped support sleeve 301 during surgery, thereby improving safety while saving certain costs.

[0052] Then, the arc-shaped support sleeve 301 is placed in the patient's oral cavity for preliminary support and expansion, and then the push rod 16 is pushed. The push rod 16 will drive the gear 17 to rotate, and then the gear 17 will drive the rack 18 meshing with it to move along the inner wall of the moving cavity. Since the rack 18 is close to the slider 21 and the slider 21 and the guide rod 9 are fixedly connected, and since the slider 21 slides with the moving cavity and the guide rod 9 slides with the main body 8, when the rack 18 moves, it will push the slider 21 and the guide rod 9 to slide along the main body 8; at the same time, because the surface of the slider 21 is provided with a spiral groove 20 and the inner surface of the moving cavity is fixed with a guide block 19 that cooperates with the groove 20, when the slider 21 moves along the moving cavity, the guide block 19 will slide relatively along the spiral groove 20, thereby causing the slider 21 to rotate and drive the guide rod 9 to rotate.

[0053] When the guide rod 9 slides to the right along the main body 8, since the first telescopic rod 5 and the second telescopic rod 26 can perform telescopic movement, the distance between the first support 1 and the second support 6 can change accordingly, so that the distance between the two arc-shaped support sleeves 301 gradually increases, thereby gradually expanding the patient's mouth. At the same time, during the movement, the doctor can always observe the changes in the patient's expression, and control the degree of expansion of the patient's mouth without affecting the surgical operation, so as to reduce the discomfort caused to the patient by a large expansion; when the patient's mouth expands to a suitable position, the locking sleeve on the second telescopic rod 26 is rotated to limit the telescopic movement of the second telescopic rod 26, so that the distance between the first support 1 and the second support 6 is fixed, and then the distance between the two arc-shaped support sleeves 301 is fixed to ensure the stability of the device during surgery.

[0054] Embodiment 2:

[0055] The difference from the above embodiment is that, as shown in the attached Figure 3 and Figure 4 As shown: the first support 1 has a first groove 4 and a second groove 27 on one side close to the second support 6, the first telescopic rod 5 is located in the first groove 4, a plurality of electromagnets 11 and a plurality of second springs 12 are welded in the first groove 4; the length of the second springs 12 is greater than the length of the electromagnet 11, and a positioning ring 14 is provided in the first groove 4; the positioning ring 14 is sleeved on the first telescopic rod 5, the positioning ring 14 and the first telescopic rod 5 are slidably matched, and a magnetic absorption layer 13 is bonded to the side of the positioning ring 14 close to the electromagnet 11; the electromagnet 11 is electrically connected to the controller.

[0056] A plurality of bearings 15 are bonded in the second groove 27, and the bearings 15 are rotatably connected to the guide rod 9. The guide rod 9 is located at one end of the second groove 27 and has a plurality of blades 23 integrally formed thereon. A signal sensor 24 is fixedly connected with screws in the second groove 27; the signal sensor 24 is located in the motion trajectory of the blade 23, and the signal sensor 24 is electrically connected to the controller.

[0057] A lighting assembly is bonded to the positioning ring 14, and the lighting assembly includes a plurality of LED lamps, and the LED lamps are all connected to the controller signal. A position sensor 25 is bonded to the connection between the second support 6 and the first telescopic rod 5; and the position sensor 25 is connected to the controller signal.

[0058] The specific implementation process is as follows: when the guide rod 9 rotates, the blade 23 integrally formed with the guide rod 9 will also rotate. At the same time, since the signal sensor 24 is located within the movement trajectory of the blade 23, the signal sensor 24 will be triggered when the blade 23 rotates and a rotation signal will be generated and transmitted to the controller. Then the controller controls the electromagnet 11 to cut off power. At this time, the electromagnet 11 will not adsorb the magnetic attraction layer 13. At the same time, since the positioning ring 14 will squeeze the second spring 12 when the electromagnet 11 adsorbs the magnetic attraction layer 13; therefore, after the electromagnet 11 is powered off, the positioning ring 14 will slide out from the first groove 4 and along the first telescopic rod 5, so that the subsequent doctor can quickly move the positioning ring 14 to the specified position.

[0059] When the positioning ring 14 is moved, the position sensor 25 will detect the distance between the position sensor 25 and the positioning ring 14 in real time, and transmit the distance information to the controller in real time. The controller will judge whether the positioning ring 14 is in place based on the distance value pre-set by the controller based on the actual situation of the patient. When the positioning ring 14 moves to the predetermined position, the controller will control the LED light on the positioning ring 14 to light up to illuminate the position of the patient's gingival tumor, and the controller will light up the corresponding LED light based on the pre-set surgical area controller, so as to accurately illuminate the area where the patient's gingival tumor needs to be removed. Although some normal tissue will inevitably be removed during the gingival tumor surgery to ensure that the gingival tumor will not recur, the doctor will inevitably remove more normal tissue during the operation, thereby affecting the subsequent postoperative recovery of the patient. The pre-set surgical area will be illuminated by the LED light, so as to remind the doctor at all times, so that the doctor can observe whether the resection is performed according to the pre-set area, and it is also convenient for the doctor to observe the details of the patient's diseased area, thereby reducing the range of normal tissue resection and the possibility of gingival tumor recurrence.

[0060] After the operation, the electromagnet 11 is energized, and the positioning ring 14 is moved into the first groove 4. The electromagnet 11 will adsorb the magnetic layer 13 to secure the positioning ring 14 in the first groove 4. At the same time, when the positioning ring 14 is adsorbed and fixed, it will squeeze the second spring 12 in the first groove 4, thereby preparing for the next use.

[0061] Embodiment 3:

[0062] The difference from the above embodiment is that, as shown in the attached Figure 2 As shown: a straw 7 is bonded to the side of the second support 6 away from the first support 1; a suction head is threadedly connected to one end of the straw 7 close to the adjacent holder 2, and the other end of the straw 7 is connected to a negative pressure machine.

[0063] The specific implementation process is as follows: Under normal circumstances, when performing an epiphyseal tumor resection surgery, a large amount of blood will flow out of the patient's diseased part. The suction head connected to the suction tube 7 is brought close to the diseased part, and the negative pressure machine is started at the same time to suck away the blood to prevent the blood from flowing into the patient's respiratory tract and causing medical accidents. At the same time, because epiphyseal tumors are prone to recurrence, the epiphyseal tumor and some surrounding healthy tissues are generally removed in clinical medicine, and part of the alveolar bone is removed. The removed parts are quickly sucked away by the suction head to prevent the removed tissues from falling into the patient's esophagus or respiratory tract, thereby improving the safety and reliability of the operation. At the same time, through the adsorption effect of the negative pressure machine, a relatively closed and pressure-stable environment is created for the epiphyseal tumor resection area, thereby reducing the tension on the wound surface to promote the regeneration and repair of tissue cells, and the negative pressure effect can also improve local blood circulation, provide sufficient nutrition and oxygen to the wound, and further accelerate the healing process of the wound. At the same time, in papilla reconstruction surgery, the relatively closed and stable pressure environment created by the negative pressure machine can help maintain the stability and accuracy of the surgical area to a certain extent, thereby improving the precision of the surgical operation, and indirectly improving the success rate of the operation and the speed of wound healing. In the process of repairing papilla defects, the growth of granulation tissue is an important part of the wound healing process. It is related to whether the defective part of the patient's papilla can be restored to its original state. The negative pressure environment formed by the negative pressure machine stimulates the growth of granulation tissue, which helps to fill and repair the defect area.

[0064] Embodiment 4:

[0065] The difference from the above embodiment is that a new method for repairing the gingival papilla defect after gingival tumor resection by simultaneous gingival papilla reconstruction includes the following steps:

[0066] Step 1, disinfection and installation: disinfect the two arc-shaped support sleeves 301 to be used, and then insert the corresponding card blocks 303 of the two arc-shaped support sleeves 301 into the corresponding card slots, press the buckle 10, insert the buckle 10 into the corresponding card hole 304, and fix the two arc-shaped support sleeves 301 on the first support 1 and the second support 6 respectively.

[0067] Step 2: support and fixation: put the two arc-shaped support sleeves 301 into the patient's mouth for preliminary support, and then push the push rod 16, so that the gear 17 drives the rack 18 to slide along the inner wall of the movable cavity, so that the first support 1 and the second support 6 move, and the distance between the two arc-shaped support sleeves 301 gradually increases, so as to open the patient's mouth to a suitable position, provide more operating space for the doctor, and facilitate the doctor to observe and understand the condition of the patient's diseased part. After the arc-shaped support sleeve 301 expands the patient's mouth to a suitable degree, the position of the two arc-shaped support sleeves 301 is fixed by the fixing component.

[0068] Step three, positioning lighting: based on the pre-set patient information and the information from the position sensor 25, move the positioning ring 14 to the position corresponding to the surgical site of the patient, and illuminate the surgical site through the LED light on the positioning ring 14, to provide the doctor with a brighter surgical environment, so that the doctor can more clearly observe the specific condition of the patient's diseased part during the operation, thereby facilitating the doctor's operation and improving surgical efficiency.

[0069] Step 4, negative pressure adsorption: Start the negative pressure machine and move the suction head close to the gingival tumor to suck away the blood from the patient's wound during the gingival tumor removal surgery, as well as part of the alveolar bone that is inevitably removed, thereby reducing the possibility of these tissues entering the patient's respiratory tract and causing harm.
