Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a novel opening device for the oral cavity. Background Technology

[0002] Oral retractors are auxiliary medical devices used for oral examination and observation. They help maintain the patient's oral cavity in an open state, making it easier for doctors to observe the inside of the oral cavity. Existing oral retractors include: forceps-type mouth openers, which are mostly used for routine examinations; T-type mouth openers, which are mostly used for emergency intubation and pharyngeal surgery; and mouth openers, which are mostly used for active mouth opening for short-term observation operations.

[0003] The forceps mouth opener is a commonly used oral retraction device. It uses a lever structure to allow for single-handed operation and is generally set to 30 / 45 / 60mm opening angles to precisely control the mouth opening range. However, the degree of jaw opening varies considerably among patients, including children and adults, as well as oral patients and healthy individuals. The simple settings are not convenient enough in actual use. In addition, the forceps mouth opener usually applies a force of 18-25N, with a force of 12-15N for children. The force needs to be controlled based on the doctor's experience, and the opening force cannot be monitored. Excessive opening force can easily injure the patient. Utility Model Content

[0004] The technical problem this invention aims to solve is that the opening setting of the clamp-type mouth opener is fixed, its applicability is generally limited, and the opening force cannot be monitored.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes a novel opening device for the oral cavity, comprising two sets of forceps arms, the middle parts of the two sets of forceps arms being rotatably connected by a connector, each forceps arm comprising a support end and a gripping end, the gripping end of the two sets of forceps arms having an arc-shaped handle on the outer side and a monitoring component on the inner side.

[0006] The monitoring component includes a support sleeve and a sliding rod respectively disposed at the gripping ends of two sets of clamp arms. The bottom wall of the support sleeve is provided with a pressure sensor and the inner two side walls are provided with guide grooves. The pressure sensor is provided with a support plate. A sliding plate slides in the guide groove. Two sets of support springs are provided between the support plate and the sliding plate and are connected to the support plate and the sliding plate at their respective ends. The upper end of the sliding rod is hinged to one set of gripping ends of the clamp arms and the other end is hinged to the sliding plate. The side wall of the support sleeve is also provided with a display screen that is qualitatively connected to the pressure sensor.

[0007] Preferred technical solution 1: The gripping end of the clamp arm is also provided with adjustment grooves. An adjustment screw is fixedly installed through one set of adjustment grooves. The other end of the adjustment screw extends through and to the other end of another set of adjustment grooves, and is connected to a wing nut by a thread.

[0008] Preferred technical solution 2: The support end of the clamp arm is provided with a connecting block that rotates on the side. Two sets of connecting blocks are detachably connected with a support plate. The support plate is arc-shaped and has a meshing groove on the opposite side.

[0009] Preferred technical solution 3: The connecting block is provided with a magnet, and the side wall of the tray is provided with a slot and a magnetic suction component corresponding to the magnet is provided inside.

[0010] Preferred technical solution four: The sliding rod is also provided with scale markings.

[0011] Preferred technical solution five: The arc-shaped grip is made of medical-grade silicone.

[0012] The present invention proposes a novel opening device for the oral cavity, and the beneficial effects achieved by adopting the above structure are as follows:

[0013] (1) Real-time monitoring and quantitative display of the spreading force significantly improves operational safety and accuracy. The monitoring component, consisting of a pressure sensor, support spring, sliding plate, sliding rod, and display screen, can convert the pressure applied to the gripping end of the forceps arm (i.e., spreading force) into a visual numerical value displayed on the screen in real time. This allows doctors or operators to intuitively and accurately monitor the applied spreading force, effectively avoiding the risk of damage to oral tissues (such as teeth, gums, and joints) due to excessive force, and improving the controllability and safety of the operation;

[0014] (2) The stepless adjustable opening force locking function utilizes the adjusting screw and wing nut that run through the adjustment slots of the two sets of clamp arm gripping ends. The operator can easily tighten the nut in any opening state to firmly lock the opening angle and opening force of the clamp arm, ensuring a stable and reliable opening state, preventing accidental closure of the instrument during the operation, and greatly enhancing the adaptability and ease of operation of the device.

[0015] (3) The design of the detachable magnetic tray enhances the stability, comfort and hygiene flexibility of the support. The support end is connected to the detachable arc-shaped tray by a connecting block. The tray has an occlusal groove and uses magnets and magnetic components to achieve quick assembly and disassembly. The shaped tray fits the jaw surface, and the occlusal groove fixes the position of the teeth, providing uniform and stable support, reducing slippage and improving patient comfort. The tray can be quickly disassembled, which is convenient for thorough cleaning and disinfection, effectively avoiding cross-infection and complying with medical standards. Different specifications or shapes of trays can be replaced according to the patient's oral cavity size, tooth shape (such as children, adults, patients with missing teeth) or specific surgical requirements, so that the opening force is distributed more evenly and the application range is wider.

[0024] Example 1

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A novel opening device for the oral cavity includes two sets of clamp arms 1, the middle parts of the two sets of clamp arms 1 are rotatably connected by a connector, the clamp arm 1 includes a support end and a gripping end, the gripping end of the two sets of clamp arms 1 is provided with an arc-shaped handle 2 on the outer side and a monitoring component 3 on the inner side.

[0026] The monitoring component 3 includes a support sleeve 4 and a sliding rod 5 respectively located at the gripping ends of the two sets of clamp arms 1. The bottom inner wall of the support sleeve 4 is provided with a pressure sensor 6 and the inner two side walls are provided with guide grooves 7. The pressure sensor 6 is provided with a support plate 8. The sliding plate 9 slides in the guide grooves 7. Two sets of support springs 10 are provided between the support plate 8 and the sliding plate 9, and their two ends are respectively connected to the support plate 8 and the sliding plate 9. The upper end of the sliding rod 5 is hinged to the gripping end of one set of clamp arms 1 and the other end is hinged to the sliding plate 9. The side wall of the support sleeve 4 is also provided with a display screen 11 that is qualitatively connected to the pressure sensor 6 to display the pressing force, making the operation force intuitive and avoiding excessive opening that could cause injury.

[0027] like Figure 2 As shown, the gripping end of the clamp arm 1 is also provided with adjustment grooves 12. An adjustment screw 13 is inserted and fixed in one set of adjustment grooves 12. The other end of the adjustment screw 13 is inserted and extended to the other end of another set of adjustment grooves 12. At the same time, a wing nut 14 is connected by a thread, thereby locking the opening force and realizing stepless adjustment and fixation.

[0028] Example 2

[0029] Based on Example 1, such as Figure 2 As shown, to further facilitate stable support for the upper and lower jaws, a connecting block 15 is rotatably provided on the side of the support end of the clamp arm 1. A tray 16 is detachably connected to each of the two connecting blocks 15. The tray 16 is arc-shaped and has an occlusal groove 17 on its opposite side. Magnets are provided on the connecting blocks 15, and slots are provided on the side walls of the tray 16, with magnetic suction components corresponding to the magnets inside. The detachable design facilitates replacement, cleaning, and disinfection of the tray 16, and allows for flexible adjustment for teeth of different sizes and shapes, resulting in more even opening force.

[0030] like Figure 3 As shown, the sliding rod 5 is also equipped with scale markings 18, which allow for direct observation of the opening size.

[0031] Among them, the curved grip 2 is made of medical-grade silicone, which has good softness and anti-slip properties.

[0032] In practical use, preparation and assembly are as follows: Replace the tray 16 by aligning the slot on the side wall of the tray 16 with the connecting block 15. Quickly attach and fix it using magnets and magnetic chucks to ensure a stable installation. The operator holds the arc-shaped handles 2 of the two sets of clamp arms 1, gently placing the support end into the patient's mouth so that the two sets of trays 16 fit against the upper and lower teeth respectively. Adjust the angle of the trays 16 so that the connecting block can rotate, allowing the occlusal grooves 17 to engage the patient's teeth for stable support. Slowly pinch the two sets of handles together, causing the clamp arms 1 to rotate around the connecting block, gradually opening the mouth. The sliding rod 5, following the movement of the clamp arms, pushes the sliding plate 9 to slide within the guide groove 7. The sliding plate 9, through the support spring 10, presses... Force is transmitted to support plate 8, pressure sensor 6 detects pressure value in real time and displays it on display screen 11. Operator simultaneously observes and quantitatively monitors the opening force to avoid exceeding the safety threshold. The scale mark 18 of sliding rod 5 directly reads the opening size. When the target opening size and force are reached, maintain the grip and rotate the wing nut 14 to tighten it along the adjusting screw 13 to achieve stepless locking of the clamp arm angle, freeing the operator's hands and maintaining a stable opening state. If fine adjustment of the opening degree is required: first slightly loosen the wing nut 14, adjust the grip force to the new target value, and then tighten the nut again to ensure stable force during the operation and avoid abnormal pressure increase due to patient movement.

[0033] Release and disassembly: Operation completed: First, fully loosen the wing nut 14, then slowly release the gripping force to gradually close the clamp arm 1, remove the device, press down the support plate 16 to overcome the magnetic attraction and separate it from the connecting block 15, perform independent cleaning and disinfection, clean the support sleeve 4, sliding rod 5 and other parts, and store them properly.
