Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a buccal and lingual mucosa protection device. Background Technology

[0002] In cases where subgingival tooth preparation is not feasible and a rubber dam cannot be used, a buccal and lingual mucosal protection device is employed to ensure operational safety, effective isolation, and patient comfort.

[0003] However, to prevent patients from accidentally injuring their buccal and lingual mucosa with high-speed rotating burs during tooth extraction, a patent document with publication number CN208942427U describes a method that uses a tongue mucosa protection arm to keep the tongue outside the surgical area, maximizing the exposure of the surgical field and preventing damage to the tongue mucosa from high-speed burs. Simultaneously, the cutting edge can buccally pull the free gingival flap and isolate the buccal mucosa in the surgical area, expanding the surgical field and preventing accidental injury to the buccal gingival flap and buccal mucosa by the high-speed bur. The rounded cutting edge, with smooth transitions on both sides, avoids unintentional scratches to the gums or buccal mucosa caused by sharp edges.

[0004] Based on the above-disclosed technical content, theoretically, the implementation of the relevant technical structure is beneficial to the protection of the patient's buccal and lingual mucosa. However, according to the description in the above-disclosed technical content, when medical staff hold the handle to control the buccal and lingual mucosa protection device, since medical staff wear gloves to comply with hygiene regulations when performing oral procedures on patients, the handle comes into contact with the medical staff's gloves. At this time, the smooth surface of the handle, combined with the smooth surface of the gloves, makes it easy for medical staff to slip on the medical staff's gloves when using the handle, thus making it inconvenient for medical staff to grip the handle tightly and affecting the normal use of the buccal and lingual mucosa protection device.

[0023] Please see Figure 1 and Figure 6 A buccal and lingual mucosa protection device includes a blade foot 1. A connecting rod 2 is fixedly installed on the upper end of the blade foot 1. The connecting rod 2 connects the blade foot 1 to a handle 4. The end of the connecting rod 2 away from the blade foot 1 is movably installed to the handle 4 via a quick-release assembly 3. The blade foot 1 can be disassembled or installed by changing the connection method between the quick-release assembly 3 and the connecting rod 2. A protective sleeve 5 is fixedly sleeved on the outer wall of the handle 4. The protective sleeve 5 connects the handle 4 to anti-slip ridges 6. Anti-slip ridges 6 are evenly distributed on the outer wall of the protective sleeve 5. A first protective plate 7 is hinged to the back of the blade foot 1 via a first hinge. The first protective plate 7 and the second protective plate 8 are designed to block the tongue during oral surgery. The end of the first protective plate 7 away from the blade foot 1 is hinged to the second protective plate 8 via a second hinge. Bolts are threaded onto the inner walls of both the first and second hinges. The bolts are installed on the hinges to fix the first protective plate 7 and the second protective plate 8 after the position is adjusted.

[0024] The lower end of the blade foot 1 is provided with rounded edges 9 on the left and right sides respectively. The rounded edges 9 reduce the discomfort after the blade foot 1 comes into contact with the patient's mouth. A baffle 10 is fixedly installed on the upper end of the blade foot 1, and the end of the baffle 10 away from the blade foot 1 is fixedly connected to the lower end of the connecting rod 2. The installation of the baffle 10 serves to connect the connecting rod 2 and the blade foot 1.

[0025] Please see Figure 2 and Figure 3 The upper end of the connecting rod 2 is provided with a groove 14 located below the handle 4. The bottom surface of the inner wall of the groove 14 is provided with a cylindrical groove 12. The outer wall of the cylindrical groove 12 is provided with limit grooves 13 evenly. The left and right sides of the groove 14 are respectively provided with through holes 11, and the inner wall of the through hole 11 is movably connected with the outer wall of the quick release component 3. By changing the connection method between the quick release component 3 and the through hole 11, the handle 4 can be taken out or put in from the connecting rod 2.

[0026] The lower end of the handle 4 is fixedly mounted with a mounting plate 16 located above the connecting rod 2. The end of the mounting plate 16 away from the connecting rod 2 is fixedly connected with a protrusion 15 for installing the quick-release component 3. The outer wall of the protrusion 15 is movably engaged with the inner wall of the groove 14. The engagement between the protrusion 15 and the groove 14 restricts the installation position of the lower end of the handle 4 within the connecting rod 2.

[0027] Please see Figure 5 and Figure 4 The quick-release assembly 3 includes a spring 301 and a moving block 302. One end of the spring 301 is fixedly connected to the inner wall of the protrusion 15. The spring 301 is used to connect the moving block 302 and the protrusion 15. The moving block 302 is fixedly installed at the end of the spring 301 away from the protrusion 15, and the outer wall of the moving block 302 is movably sleeved with the inner wall of the through hole 11.

[0028] A round rod 17 is fixedly installed on the lower end face of the protrusion 15, and the outer wall of the round rod 17 is movably sleeved with the inner wall of the cylindrical groove 12. The sleeve of the round rod 17 with the cylindrical groove 12, combined with the snap-fit ​​of the limiting block 18 and the limiting groove 13, restricts the installation position of the connecting rod 2 and the handle 4.

[0029] Working principle: During use, firstly, when the patient is undergoing dental treatment, the gingiva is incised, the flap is raised, and then the buccal mucosa protection device is used. After the blade 1 opens the incision, the free gingival flap can be pulled buccally, expanding the surgical field and preventing accidental injury to the buccal gingival flap and buccal mucosa by the high-speed bur. Then, the positions of the first protection plate 7 and the second protection plate 8 are adjusted according to the individual patient's tongue condition. Because the blade 1, the first protection plate 7, and the second protection plate 8 are connected by a hinge, the first protection plate 7 and the second protection plate 8 can move. Combined with the bolts threaded at the upper end of the hinge, the first protection plate 7 and the second protection plate 8 can be positioned... After the guard plate 8 is fixed in position, the first guard plate 7 and the second guard plate 8 block the tongue. Finally, when it is necessary to replace the used cutting foot 1, press the moving block 302 to move it into the inside of the protrusion 15. At this time, the spring 301 is compressed until the moving block 302 is completely retracted into the inside of the protrusion 15. Then, remove the connecting rod 2 from under the quick release assembly 3. When the new cutting foot 1 is installed, the spring 301 rebounds and pops the moving block 302 out of the inside of the protrusion 15 to the outside of the through hole 11, so that the quick release assembly 3 connects the connecting rod 2 to the quick release assembly 3, thereby achieving the replacement of the new cutting foot 1.
