Description

Technical Field

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

[0002] In the clinical diagnosis and treatment of oral and maxillofacial surgery, tumor resection is a common treatment option. The oral and maxillofacial region has a complex anatomical structure, containing numerous important blood vessels, nerves, and functional organs such as teeth, salivary glands, and facial muscles. Furthermore, tumors vary in location, size, and morphology, and the boundary between them and surrounding normal tissue is sometimes unclear, posing significant surgical challenges.

[0003] The patent named Tumor Clamping Device for Oral and Maxillofacial Surgery, with publication number: CN113143406B, proposes that the traditional clamping device requires the hand to clamp it with force and maintain the same posture when clamping. When the clamping state needs to be maintained for a certain period of time, it will cause soreness, which is very inconvenient to use and also increases the workload of medical staff. The adjusting column can slide along the length direction of the mounting strip, and the operating rod supports the patient's upper and lower teeth through the two supporting columns, so that the patient's mouth is in an open state. The two mounting strips are arranged slightly away from the patient's mouth through the connecting piece to avoid taking up too much space, which effectively increases the surgical operation space. Since the adjusting column can slide along the length direction of the mounting strip, and the operating rod is connected to the adjusting column through the mounting piece, and the operating rod can move back and forth The operation rod can be adjusted in multiple directions and angles to facilitate clamping operations at different positions. The adsorption component is provided in the operation rod to adsorb the tumor to prevent the tumor from moving during or after cutting. A retractable clamping component is provided on the periphery of the adsorption component. On the one hand, it can open the surgical incision process. After the resection is completed, the clamping component can be retracted to clamp and remove the tumor after cutting, freeing the hands of medical staff. However, in the process of clamping the tumor, the overall clamping method uses hard claws. When using hard claws to move the tumor, it is easy to cause the claws to scratch or puncture the outer wall of the tumor, causing damage to the tumor. Once the tumor is damaged, it is easy to cause more complications. For this reason, a tumor clamping device for oral and maxillofacial surgery is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Figure 1As shown, the present application discloses a tumor clamping device for oral and maxillofacial surgery, comprising a sleeve 100. The exterior of the sleeve 100 is connected to a positioning structure. One end of the sleeve 100 is fixedly connected to a containment cover 101. A transparent balloon 102 is fixedly connected to the interior of the containment cover 101. A suction hole 105 is provided at the center of the transparent balloon 102. A delivery tube 103 is connected to the interior of the transparent balloon 102. A suction tube 104 is connected to the interior of the suction hole 105. The transparent balloon 102 is configured to contact an oral and maxillofacial tumor when inflated, and gradually discharge gas from the transparent balloon 102 through the delivery tube 103, so that the transparent balloon 102 gradually condenses and adheres to the outside of the tumor, thereby forming a close clamping of the tumor. The interior of the transparent balloon 102 is connected to an internal clamping structure. Among them, the inner clamping structure is used to form a secondary clamp on the root of the tumor after the transparent balloon 102 is attached to the tumor surface. The outside of the inner clamping structure is connected to a retaining structure, which is used to position the inner clamping structure and the attached transparent balloon 102.

[0020] Specifically, during use, the medical staff can use the positioning structure to open the human oral cavity. After opening the human oral cavity, the medical staff can hold the cannula 100 and connect the air pump through the delivery tube 103. After connecting the air pump, start the air pump to continuously inject gas into the interior of the delivery tube 103. After continuously injecting gas into the interior of the delivery tube 103, the delivery tube 103 will continuously transport the gas to the interior of the transparent balloon 102. When the gas enters the interior of the transparent balloon 102, the transparent balloon 102 will expand. When the transparent balloon 102 expands, the medical staff can press the expanded transparent balloon 102 against the patient's oral and maxillofacial tumor. After the top connection is completed, the transparent balloon 102 is placed in the airtight container. The gas inside 02 is slowly released through the delivery tube 103, so that the delivery tube 103 slowly softens along the surface of the tumor, and when the delivery tube 103 continues to soften, the suction tube 104 is connected to the air inlet end of the air pump, so that the suction tube 104 cooperates with the suction hole 105 to form a suction effect. When the transparent balloon 102 continues to soften and an adsorption effect is generated at the center, the gradually softened transparent balloon 102 can be completely wrapped around the outer surface of the tumor, thereby achieving an overall wrapping clamping of the tumor. The transparent balloon 102 is made of a soft medical transparent material as a whole. While achieving an observable wrapping clamping, it will not cause excessive hard squeezing of the tumor, thereby avoiding squeezing and causing damage to the tumor.

[0021] like Figure 1As shown, the positioning structure includes two threaded lifting rods 500, and the upper and lower ends of the threaded lifting rods 500 are rotatably connected to the tooth pads 501. The tooth pads 501 at the upper and lower ends are respectively connected to the tooth contact surfaces, and the outside of the tooth pads 501 are fixedly connected to the connecting plates 502. The four connecting plates 502 are divided into two groups. The two groups of connecting plates 502 are fixedly connected to the side of the threaded lifting rods 500 respectively. The inside of the arcuate connecting seat 503 is slidably connected to the first set rod 504, the outside of the first set rod 504 is fixedly connected to the first ring 507, the outside of the first ring 507 is fixedly connected to the U-shaped seat 508, and the sleeve 100 is mounted inside the U-shaped seat 508.

[0022] Specifically, during use, the staff installs the two bite pads 501 to the position of the human oral cavity and connects the bite pads 501 to the position of the human teeth. After the bite pads 501 are connected to the position of the human teeth, the threaded telescopic rod in the threaded lifting rod 500 is rotated to open the human oral cavity. After the human oral cavity is opened, the first set of rods 504 is installed in conjunction with the threaded column 505 to the center slot of the two arc-shaped connecting seats 503, and the first set of rods 504 is moved through the center slot. After the movement is completed, the threaded column 505 is threadedly connected with the bolt 506, so that the two ends of the first set of rods 504 are tightened and limited by the bolt 506. After the first set of rods 504 is limited, the medical staff can install the sleeve 100 on the U-shaped seat 508, and the first ring 507 can slide on the first set of rods 504, which is convenient for the medical staff to adjust the U-shaped seat 508 to the appropriate position according to the tumor condition.

[0023] like Figure 1 As shown, the outside of the delivery pipe 103 is connected to the electric-controlled diverter valve 900, and one of the air inlets and outlets of the electric-controlled diverter valve 900 is connected to the diverter pipe 901. The end of the diverter pipe 901 away from the electric-controlled diverter valve 900 passes through the outer wall of the first ring 507 and is connected to the expansion and extrusion sac 902. The outside of the expansion and extrusion sac 902 is connected to the connecting pipe 903. The end of the connecting pipe 903 away from the expansion and extrusion sac 902 is connected to the side extrusion sac 904. The side extrusion sac 904 is fixedly connected to the inside of the U-shaped seat 508, and the expansion and extrusion sac 902 is fixedly connected to the inside of the first ring 507.

[0024] Specifically, when positioning the first ring 507 and the U-shaped seat 508, the gas entering the delivery pipe 103 from the air pump can be diverted to the inside of the diverter pipe 901 by opening the electrically controlled diverter valve 900. When the gas enters the diverter pipe 901, the diverter pipe 901 will deliver the gas to the inside of the expansion and extrusion bladder 902, and the expansion and extrusion bladder 902 will deliver the gas to the inside of the connecting pipe 903, and the connecting pipe 903 will further deliver the gas to the side extrusion bladder. Inside 904, when the expansion and squeezing bladder 902 is expanded, the first sleeve rod 504 will be clamped and limited, thereby positioning the first ring 507 outside the first sleeve rod 504, and when the side squeezing bladder 904 is expanded, the sleeve 100 located inside the U-shaped seat 508 will be squeezed and limited, thereby ensuring the stability of the sleeve 100 inside the U-shaped seat 508, and overall realizing the limitation and fixation of the sleeve 100 when the sleeve 100 is erected inside the U-shaped seat 508.

[0025] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to the prior art, in this embodiment, the pre-inflated transparent balloon 102 is adhered to the tumor surface, and the gas inside the transparent balloon 102 is slowly released after the adhesion is completed. At the same time, the air between the tumor and the adhered surface of the transparent balloon 102 is sucked through the suction hole 105 and the suction tube 104. As the gas inside the transparent balloon 102 is slowly released, the gas between the two is continuously sucked out, so that the transparent balloon 102 can firmly adsorb the outside of the tumor after releasing a certain amount of gas, completing the adsorption and clamping action as a whole. The soft-wrapped clamping effect can achieve the clamping effect of the tumor, and avoid the tumor damage caused by hard clamping.

[0026] Example 2: Considering that during the clamping process, when the gas inside the transparent balloon 102 is slowly discharged, because the front of the transparent balloon 102 is constantly pressing against the tumor mass, most of the already flaccid transparent balloon 102 is attached to the outside of the tumor. However, when it reaches the root of the tumor, the flaccid transparent balloon 102 is unable to wrap the root of the tumor. To address the above technical problems, the present application proposes the following technical solutions, specifically: like Figure 2-Figure 4 As shown, the inner clamping structure includes an elastic clamping claw 200, the outer wall of the elastic clamping claw 200 is integrally formed inside the transparent balloon 102, and one end of the elastic clamping claw 200 passes through the inner wall of the transparent balloon 102 and is fixedly connected to the inner wall surface of the enclosure cover 101.

[0027] Specifically, during use, when the transparent balloon 102 expands into a sphere, the front ends of the multiple elastic claws 200 are in an open state. When the gas inside the transparent balloon 102 is gradually discharged and the transparent balloon 102 gradually becomes soft, the end of the elastic claws 200 close to the tumor will gradually shrink toward the center of the suction hole 105, thereby driving the soft transparent balloon 102 to move closer to the center of the tumor and clamping the root of the tumor.

[0028] Furthermore, the shape of the multiple elastic clamping claws 200 is similar to that of the existing octopus head massager.

[0029] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to embodiment 1, in this embodiment, when the transparent balloon 102 gradually deflates and becomes flaccid and adheres to the surface of the tumor, the elastic clamp 200 located inside the transparent balloon 102, one end close to the suction hole 105, will also gradually close, thereby driving the flaccid transparent balloon 102 to approach the root of the tumor, thereby driving the transparent balloon 102 to adhere to the root of the tumor.

[0030] Embodiment 3: Considering that during use, although the elastic clamping jaws 200 can drive the flaccid transparent balloon 102 to clamp the root of the tumor, the clamping capacity of the elastic clamping jaws 200 is limited during the clamping process. After reaching the designated circle neck, the elastic clamping jaws 200 will stop moving towards the center. When the elastic clamping jaws 200 are completely retracted, but the flaccid elastic clamping jaws 200 have not yet completely adhered to the root of the tumor and there are still a lot of gaps, the transparent balloon 102 will still easily detach during the overall clamping process. In response to the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 2-Figure 8 As shown, the enclosure structure includes a plurality of hanging rings 300, and the plurality of hanging rings 300 are respectively fixedly connected to the outer wall of the elastic clamp 200, and the side of the hanging ring 300 away from the elastic clamp 200 passes through the outer wall of the transparent balloon 102, and the interior of the plurality of hanging rings 300 is wrapped with a tightening rope 301, and the end of the tightening rope 301 forms a tightening buckle, and a blue light lamp 302 is placed on the outside of the tightening rope 301, and the light irradiation end of the blue light lamp 302 directly irradiates the tightening rope 301.

[0031] Specifically, when the elastic clamp 200 drives the flaccid transparent balloon 102 close to the root of the tumor, the medical staff can also tighten the tightening rope 301 wrapped around the outside of the hanging ring 300. When the tightening rope 301 is tightened, the transparent balloon 102 and the elastic clamp 200 will shrink again, thereby driving the transparent balloon 102 to form a bundling effect on the root of the tumor. When the bundling effect is formed, the tumor can be completely wrapped, reducing the separation between the transparent balloon 102 and the tumor. At the same time, when the bundling effect is formed, the medical staff can hold the blue light lamp 302 to irradiate the tightening rope 301. When the tightening rope 301 is irradiated by the light emitted by the blue light lamp 302, it will solidify. When solidified, it can reduce the need for medical staff to continuously tighten the tightening rope 301.

[0032] Furthermore, the material of the tightening rope 301 is a transparent silicone tape filled with light-curing gel, and the blue light range emitted by the blue light irradiation lamp 302 is 405nm, and the light intensity is 80-100mW / cm². like Figure 5-Figure 9 As shown, the end of the tightening rope 301 away from the hanging ring 300 is fixedly connected to the hanging plate 800, and the outside of the hanging plate 800 is integrally formed with a hanging ratchet plate 801. The end of the sleeve 100 away from the enclosure cover 101 is fixedly connected to the fixing ring 802, and the hanging ratchet plate 801 is hung on the outside of the fixing ring 802.

[0033] Specifically, when the medical staff tightens the tightening rope 301, the tightening rope 301 can be dragged by the handheld hanging plate 800. When the handheld hanging plate 800 drags the tightening rope 301, the tightening rope 301 can be tightened around the transparent balloon 102. When the tightening rope 301 does not need to be solidified, the medical staff can hang different hanging spine plates 801 on the fixing ring 802. After hanging the hanging spine plate 801 on the fixing ring 802, the hanging plate 800 and the tightening rope 301 can be fixed. The setting of multiple hanging spine plates 801 can adjust the tensioning state of the tightening rope 301. When it needs to be tightened and fixed, only the hanging spine plate 801 at the rear needs to be hung on the fixing ring 802. When it needs to be loosened, only the hanging spine plate 801 at the front needs to be hung on the fixing ring 802.

[0034] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to embodiment 2, in this embodiment, after the elastic clamp 200 drives the transparent balloon 102 to fit the root position of the tumor, the medical staff can tighten the tightening rope 301. After being subjected to the pulling force, the tightening rope 301 will be tightened through the tightening buckle formed at the end. When the transparent balloon 102 is continuously tightened by the tightening rope 301, the position of the transparent balloon 102 close to the root of the tumor can be made to fit more closely to the root of the tumor, thereby preventing the transparent balloon 102 from detaching from the tumor.

[0035] Example 4: Considering that the transparent balloon 102 softly wraps the tumor as a whole, when the position of the tumor needs to be adjusted during soft wrapping, the cannula 100 connected at the rear cannot adjust the tumor wrapped by the transparent balloon 102. To address the above technical problems, the present application proposes the following technical solutions, specifically: like Figures 1-8 As shown, a towing hook 401 is hung on the outside of the tightening rope 301 , and one end of the towing hook 401 is fixedly connected to the towing rod 400 .

[0036] Specifically, when the position of the transparent balloon 102 needs to be adjusted as a whole, the drag hook 401 can be hung as a whole on the outside of the tightening rope 301, and the tightening rope 301 can be hooked and pulled by holding the drag rod 400. When the tightening rope 301 is hooked and pulled, the tightening rope 301 can drag the enclosure cover 101 as a whole, which is convenient for medical staff to adjust the position of the wrapped and clamped tumor, and convenient for dragging the tumor as a whole to leak out of the cutting position when cutting.

[0037] like Figure 1 As shown, the positioning structure also includes a second set of rods 600, and the top and bottom of the second set of rods 600 and the first set of rods 504 are fixedly connected with threaded columns 505, the external threads of the threaded columns 505 are connected with bolts 506, the external sliding connection of the second set of rods 600 is connected with a second ring 601, and the external fixed connection of the second ring 601 is connected with a positioning seat 602, and the drag rod 400 is mounted inside the positioning seat 602.

[0038] Specifically, when the drag rod 400 needs to be fixed, the second set of rods 600 can be installed in the same way as the first set of rods 504. After the second set of rods 600 is installed, the drag rod 400 is clipped into the inside of the positioning seat 602, so that the positioning seat 602 can clamp and position the drag rod 400.

[0039] Furthermore, a rubber seat 603 is integrally formed inside the positioning seat 602, and the interior of the rubber seat 603 is filled with magnetorheological fluid 604. A conductive wire is connected inside the magnetorheological fluid 604, and the magnetorheological fluid 604 is energized through the conductive wire. The magnetorheological fluid 604 can be solidified after being energized. The solidified magnetorheological fluid 604 can drive the rubber seat 603 to further clamp the drag rod 400. Other clamping methods can also be used for the overall clamping to achieve a fixing effect.

[0040] like Figure 1-Figure 7 As shown, a sliding groove is provided on the adjacent side of the two arc-shaped connecting seats 503, and a universal ball 700 is installed on the top and bottom surfaces of the first set of rods 504 and the second set of rods 600, and the universal ball 700 is slidably connected to the inside of the sliding groove.

[0041] Specifically, the provision of the universal ball 700 can assist the first set of rods 504 and the second set of rods 600 in sliding smoothly on the arc-shaped connecting seat 503, making it convenient for medical staff to adjust the positions of the first set of rods 504 and the second set of rods 600.

[0042] Furthermore, the second ring 601 and the expansion and extrusion sac 902 are both provided with a rough surface on one side close to the second rod 600 and the first rod (504). The provision of the rough surface can increase the friction between the second rod (600) and the second ring (601), and between the first ring 507 and the first rod 504, and prevent the second ring 601 and the first ring 507 from sliding freely on the second rod 600 and the first rod 504.

[0043] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to embodiment three, in this embodiment, the solidified or unsolidified tightening rope 301 can be hooked by setting the drag rod 400 and the drag hook 401, and the tightening rope 301 is hooked and pulled by the drag hook 401, so that the enclosure cover 101 can be dragged, which facilitates medical staff to drag the tumor as a whole when performing lateral resection.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
