Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a lip gland biopsy auxiliary fixation device. Background Art

[0002] Lip gland biopsy is a biopsy of the lip gland, which is a pathological examination in which part of the lip gland lobule biopsy tissue is surgically removed under local anesthesia for microscopic analysis. The current lip gland biopsy process is as follows: the patient's lower lip is everted, the surgical site is anesthetized with a local disinfection box, and then the surgeon cuts the lower lip mucosa to expose the lip gland tissue, then clamps the lip gland with tweezers, and then uses a scalpel or surgical scissors to cut off the root, remove the lip gland tissue and send it for inspection. The current method of everting the patient's lower lip is generally to have an assistant wear gloves to evert the patient's lower lip, or the assistant uses tweezers or clamps to apply a pulling force to the lower lip to evert the lower lip. However, during the operation, saliva will remain in a secreted state, making it very easy for the assistant to slip when pulling and fixing the surgical site, resulting in secondary or multiple re-fixation, prolonging the operation time, and there is no component to control the pulling down of the patient's lower lip, and it is not easy for the assistant to control the force of pulling the patient's lower lip when pulling. Summary of the invention

[0003] The present invention provides a lip gland biopsy auxiliary fixation device, which solves the problem in the prior art that saliva secretion causes the existing clamping tool to slip easily and the assistant needs to continuously pull the patient's lower lip.

[0004] The technical solution of the present invention is achieved in this way:

[0005] A lip gland biopsy auxiliary fixation device comprises a lower frame and an upper frame, wherein first support plates are fixed on both sides of one end of the lower frame, a connecting rod is rotatably provided between the first support plates, one end of the upper frame is fixedly connected to the connecting rod, a lower fixing plate is rotatably connected inside the lower frame, the lower fixing plate can be fixedly connected to the patient's chin, an upper fixing plate is rotatably connected inside the upper frame, the upper fixing plate can be fixedly connected to the lips, and a limiting device is provided on one side of the connecting rod.

[0006] Furthermore, the side walls of the lower frame and the upper frame are both provided with oblong grooves, and the side walls at both ends of the lower fixing plate and the upper fixing plate are both fixed with rotating rods that penetrate the oblong grooves, and the rotating rods enable the lower fixing plate and the upper fixing plate to slide and rotate along the oblong grooves, and the ends of the rotating rods are both fixed with side plates, and the rotating rods are screwed with adjustment plates, and the side walls of the adjustment plates can abut against the outer side walls of the lower frame or the upper frame. The adjustment plates connected by threads allow medical staff to fix the fixing plates by simply rotating the adjustment plates, without the need for complicated tools or cumbersome steps, which greatly simplifies the operation process and improves work efficiency.

[0007] Furthermore, the limiting device includes a limiting ring fixed to a side wall of a first support plate, the limiting ring is provided with a plurality of limiting grooves, the side wall of the connecting rod is screwed with a baffle, the connecting rod is slidably connected to the limiting plate through a guide flat key, and the limiting plate is provided with limiting teeth on one side close to the limiting ring, the limiting teeth correspond to the limiting grooves one by one, and the baffle is abutted against the limiting plate through a first spring. By rotating the connecting rod, medical staff can quickly complete the locking or unlocking action without using other tools, simplifying the operation process and providing a stable clamping connection, which ensures that the position of the upper frame will not change due to accidents during the operation, thereby improving the safety of the operation.

[0008] Furthermore, the lower fixing plate and the upper fixing plate are both air suction bins, the air suction bins are connected to vacuum tubes, a sealing soft ring is provided at the air inlet of the air suction bins, and the vacuum tubes are connected to the vacuum generator through a quick connector. The air suction bins can adapt to chins and lower lips of different shapes and sizes, thereby improving the versatility of the device. The sealing soft ring ensures the sealed connection between the air suction bin and the chin or lower lip, prevents air leakage, and ensures the stability of the suction force.

[0009] Furthermore, the upper frame is provided with a slide groove on both sides of the hinged end of the upper frame and the lower frame, a second support plate slides in the slide groove, the end of the slide groove close to the connecting rod is against the second support plate through a second spring, a hinge rod is provided between the second support plates, a lower clamping plate is fixed at the center of the hinge rod, and connecting plates are hinged at both ends of the hinge rod through a torsion spring, and the end of the connecting plate away from the hinge rod is connected through an upper clamping plate. By using the lower clamping plate and the upper clamping plate in coordination, the lower lip can be clamped more stably, the movement during the operation can be reduced, and the stability of the operation can be improved. The slide groove allows the second support plate to slide in the upper frame, thereby adapting to lower lips of different lengths, thereby improving the versatility and adaptability of the fixing device.

[0010] Furthermore, the upper frame and the lower frame are both provided with rounded corner transitions at one end close to the connecting rod. The rounded corner transitions can reduce the friction and pressure on the patient's lower lip and surrounding skin, thereby improving the patient's comfort.

[0011] Furthermore, a medical adhesive layer is fixed on one side of the lower fixing plate and the upper fixing plate. The medical adhesive layer can be quickly adhered to the skin, so that the lower fixing plate and the upper fixing plate can be quickly fixed on the chin and the lower lip, thereby improving the efficiency of surgical preparation.

[0012] The beneficial effects that this technical solution can produce.

[0013] The present invention can provide a stable fixation effect through the overlap and fixation of the upper frame and the lower frame, and the wrapping of the lower lip and the chin on the auxiliary fixation device, which can effectively prevent the slippage caused by saliva secretion and avoid the need for secondary or multiple re-fixation, thereby significantly shortening the operation time and improving the operation efficiency. After the upper frame and the lower frame overlap, they can provide support for the everted lower lip, allowing the doctor to perform the operation more easily, improving the convenience of the operation, and reducing the dependence on assistants during the operation, alleviating the workload of medical staff.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] In the description of this embodiment, it is necessary to understand that the terms "center, longitudinal, lateral, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the invention.

[0026] like Figure 1-3 As shown in Figure 8, the first embodiment of the present invention provides a lip gland biopsy auxiliary fixation device, including a lower frame 1 and an upper frame 2, first support plates 3 are fixed on both sides of one end of the lower frame 1, a connecting rod 4 is rotatably provided between the first support plates 3, one end of the upper frame 2 is fixedly connected to the connecting rod 4, a lower fixing plate 5 is rotatably connected in the lower frame 1, and the lower fixing plate 5 can be fixedly connected to the patient's chin, an upper fixing plate 6 is rotatably connected in the upper frame 2, and the upper fixing plate 6 can be fixedly connected to the lips, and a limiting device 7 is provided on one side of the connecting rod 4.

[0027] During use, the upper frame 2 is rotated along the connecting rod 4, and the end of the upper frame 2 away from the connecting rod 4 is rotated in the direction away from the lower frame 1, and then the lower fixing plate 5 and the upper fixing plate 6 are fixed on the patient's chin and lower lip respectively. After the lower fixing plate 5 and the upper fixing plate 6 are fixed, the connecting rod 4 is rotated to make the upper frame 2 overlap with the lower frame 1. At this time, the lower lip is turned outward under the drive of the upper frame 2. The auxiliary fixing device is wrapped by the lower lip and the chin, which can prevent saliva from affecting the auxiliary fixing device, effectively reducing the direct contact of saliva with the biopsy area, and also reducing the potential contamination of the biopsy sample by saliva, thereby improving the sample quality. The upper frame 2 can be fixed by the connecting rod 4 through the limiting device 7, so that the upper frame 2 can always generate tension on the lower lip. Through the rotational connection between the lower fixing plate 5 and the upper fixing plate 6 and the lower frame 1 and the upper frame 2, the lower fixing plate 5 and the upper fixing plate 6 can be more flexibly adapted to the shape and height differences of the chin and lips of different patients, reducing the discomfort of the patient caused by improper fixation, and improving the comfort during the biopsy process. In addition, the auxiliary fixation device can support the everted lower lip, allowing the doctor to perform surgery more easily.

[0028] like Figure 2-3 As shown, the side walls of the lower frame 1 and the upper frame 2 are both penetrated by an oblong groove 8, and the side walls at both ends of the lower fixed plate 5 and the upper fixed plate 6 are fixed with rotating rods 9 that penetrate the oblong groove 8. The rotating rods 9 enable the lower fixed plate 5 and the upper fixed plate 6 to slide and rotate along the oblong groove 8, and the ends of the rotating rods 9 are fixed with side plates 10. The rotating rods 9 are screwed with adjusting plates 11, and the side walls of the adjusting plates 11 can be abutted against the outer side walls of the lower frame 1 or the upper frame 2. In the process of fixing the lower fixing plate 5 and the upper fixing plate 6 on the chin and the lower lip, the lower fixing plate 5 and the upper fixing plate 6 slide along the oblong groove 8 through the rotating rod 9. When the lower fixing plate 5 and the upper fixing plate 6 move to the appropriate position, the adjusting plate 11 is rotated to make the end faces of the lower frame 1 and the upper frame 2 tightly contact each other, and the lower fixing plate 5 and the upper fixing plate 6 are firmly fixed in the required position by friction, ensuring that the fixing plate can accurately fit the patient's chin and lips, avoiding biopsy failure or patient discomfort caused by loose fixation or position displacement. The oblong groove 8 allows the rotating rod 9 to slide and rotate freely within a certain range, so that the lower fixing plate 5 and the upper fixing plate 6 can adapt to the height and shape differences of the chin and lips of different patients, without the need to replace fixing plates of different sizes, thereby improving the versatility and flexibility of the device.

[0029] like Figure 2 , 4As shown, the limiting device 7 includes a limiting ring 12 fixed to the side wall of a first support plate 3, a plurality of limiting grooves 13 are provided on the limiting ring 12, a baffle 14 is screwed to the side wall of the connecting rod 4, a limiting plate 16 is slidably connected to the connecting rod 4 through a guide flat key 15, a limiting tooth 17 is provided on the side of the limiting plate 16 close to the limiting ring 12, the limiting tooth 17 corresponds to the limiting groove 13 one by one, and the baffle 14 is abutted against the limiting plate 16 through a first spring 18. The side walls of the limiting groove 13 and the limiting tooth 17 can be chamfered, and the chamfering can facilitate the rotation of the limiting tooth 17 and the limiting groove 13. The connecting rod 4 passes through the limiting ring 12, and the sliding connection of the guide flat key 15 is a prior art.

[0030] During the rotation of the upper frame 2, the connecting rod 4 rotates, and the connecting rod 4 drives the limit plate 16 to rotate through the guide flat key 15. The limit plate 16 overcomes the thrust of the first spring 18, so that the limit tooth 17 is rotated out of the limit groove 13. When the connecting rod 4 stops rotating, the first spring 18 applies thrust to the limit plate 16, and the limit tooth 17 on the limit plate 16 can be placed in the limit groove 13, so that the limit plate 16 is clamped and fixed with the limit ring 12. The limit plate 16 fixes the connecting rod 4 through the guide flat key 15. This dynamic adaptability enables the device to remain stable at different angles without manual adjustment or additional locking mechanism, thereby improving the convenience and efficiency of use. In order to facilitate the adjustment of the torque required for rotating the connecting rod 4 and make the clamping connection between the limit plate 16 and the limit ring 12 more stable, the baffle 14 screwed to the connecting rod 4 is rotated to make the baffle 14 close to the limit plate 16. The baffle 14 close to the limit plate 16 will compress the first spring 18. After the first spring 18 is compressed, the thrust on the limit plate 16 will increase, thereby making the clamping connection between the limit plate 16 and the limit ring 12 more stable. Even if the patient moves slightly or there is slight external vibration, the stability of the device can be maintained to ensure the smooth progress of the biopsy process.

[0031] like Figure 1 , 2As shown, the lower fixing plate 5 and the upper fixing plate 6 are both suction chambers 19, and the suction chamber 19 is connected to a vacuum tube 20. A sealing soft ring 21 is provided at the air inlet of the suction chamber 19, and the vacuum tube 20 is connected to the vacuum generator through a quick connector 22. The suction chamber 19, the quick connector 22 and the vacuum generator are all prior art. When the patient's beard is dense, the beard can be covered with a medical sealing tape, and the lower fixing plate 5 can be adsorbed in a suitable position. The suction force generated by the vacuum generator can ensure that the lower fixing plate 5 and the upper fixing plate 6 are closely fitted with the patient's chin and lower lip, thereby achieving a more stable fixing effect, and the suction chamber 19 can adjust the suction force as needed to adapt to the anatomical characteristics and surgical needs of different patients. The sealing soft ring 21 ensures a good seal between the suction chamber 19 and the patient's chin or lower lip, and at the same time makes the contact softer and more comfortable, reducing the pressure and discomfort caused by the suction chamber 19, which helps to improve the patient's comfort during the biopsy process and relieve their tension. The vacuum tube 20 and the vacuum generator are quickly connected through the quick connector 22, and the auxiliary fixing device can be made of disposable medical plastic, which can effectively prevent the occurrence of cross infection and ensure the safety of patients and medical staff.

[0032] like Figure 2 , 3 As shown in Figures 5 and 6, the upper frame 2 is provided with sliding grooves 24 on both sides of the hinged end of the upper frame 2 and the lower frame 1, and a second support plate 25 slides in the sliding groove 24. The end of the sliding groove 24 close to the connecting rod 4 is abutted against the second support plate 25 through a second spring 26. A hinge rod 27 is provided between the second support plates 25. A lower clamping plate 28 is fixed to the center of the hinge rod 27. Both ends of the hinge rod 27 are hinged with connecting plates 29 through torsion springs. The end of the connecting plate 29 away from the hinge rod 27 is connected through an upper clamping plate 30. The upper clamping plate 30 is hinged with the lower clamping plate 28 to form the existing clamping structure. When in use, the second support plate 25 is pushed to overcome the elastic force of the second spring 26 and move toward the direction close to the connecting rod 4. After moving to the appropriate position, the lower lip is clamped by the cooperation of the upper clamping plate 30 and the lower clamping plate 28, and the second support plate 25 is released. At this time, the second support plate 25 will be away from the connecting rod 4 by the elastic force of the spring without the action of external force, and the upper clamping plate 30 and the lower clamping plate 28 will be driven by the hinge rod 27 to apply tension to the lower lip, ensuring that the lower lip remains in an everted state during the biopsy process and will not fall off or shift due to slight movement or muscle contraction of the patient, which helps to improve the accuracy and success rate of the operation. The second support plate 25 can slide within a certain range through the slide groove 24, thereby adjusting the distance between the hinge rod 27 and the connecting rod 4, so that the lower clamping plate 28 and the upper clamping plate 30 can adapt to lower lips of different lengths and shapes, thereby improving the versatility and adaptability of the device. The slide groove 24 may be an existing T-shaped groove, and a T-shaped sliding block matching with the T-shaped groove is provided on the second support plate 25 to prevent the second support plate 25 from being separated from the slide groove 24 .

[0033] like Figure 1-7 As shown, the upper frame 2 and the lower frame 1 are both provided with a rounded corner 31 transition at one end close to the connecting rod 4. The rounded corner 31 transition design significantly reduces sharp corners, making the contact portion of the lower frame 1 and the upper frame 2 with the lower lip more rounded, and the rounded contact surface reduces irritation and pressure on the patient's skin, making the patient feel more comfortable when wearing and using the device, and can effectively prevent the patient from being injured by sharp corners during use, thereby improving the safety of the device.

[0034] The second embodiment, as Figure 7-8 As shown, a medical adhesive layer 32 is fixed to one side of the lower fixing plate 5 and the upper fixing plate 6. The medical adhesive layer 32 is a prior art, such as a medical pressure-sensitive adhesive or a medical double-sided adhesive. The medical adhesive layer 32 has strong viscosity, and the lower fixing plate 5 and the upper fixing plate 6 can be quickly attached to the patient's chin and lower lip. The quick fixation method greatly shortens the preparation time and improves the efficiency of medical operations. Due to the quick fixation property of the medical adhesive layer 32, the auxiliary fixing device can be made into a disposable appliance, avoiding the risk of cross infection caused by repeated use and incomplete disinfection. The medical adhesive layer 32 is soft and has a certain elasticity, which can adapt to the contours and curves of the patient's face, reducing the pressure and discomfort on the patient's skin.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
