Description

Technical Field

[0001] This application relates to apical surgery, and particularly to an adjustable oral soft tissue retraction and fixation device for apical surgery. Background Art

[0002] Tooth apical surgery is a common oral treatment surgery. When a doctor performs apical surgery on a tooth (especially a molar), it is necessary to first incise and dissect the gingival soft tissue flap to expose the alveolar bone surface, and then perform operations such as bone windowing, apical resection, and apical backfilling. This usually takes 1 - 1.5 hours. During the operation, an assistant or the operator himself needs to retract and fix the gingival soft tissue flap for a long time to provide a good surgical operation field. This method of manually retracting the gingival soft tissue flap is affected by muscle fatigue and the wet and slippery nature of the gingival soft tissue, and it is particularly prone to situations such as unstable retraction and slipping fixation, making it difficult to provide a stable surgical operation environment for a long time.

[0021] The adjustable oral soft tissue traction and fixation device for apical surgery of the present application will be described in detail below with reference to the accompanying drawings.

[0022] The adjustable oral soft tissue traction and fixation device for apical surgery of the present application includes: a dentition fixation member 10, a mandibular fixation member 20, and a soft tissue traction and fixation member 30.

[0023] The dentition fixation member 10 is used to be fixed in the oral cavity of the subject and is located at the upper end of the tooth row where the tooth to be treated is located; the dentition fixation member 10 includes a buckle plate 11 and an insertion rod 12; a groove is provided on the lower side of the buckle plate 11, and the buckle plate 11 is buckled on the tooth row through this groove. In specific use, the buckle plate can be adhered to the tooth row with a commonly used dental adhesive, so that the fixation can be more stable and removed after the operation. The upper end of the insertion rod 12 is fixed on the first side of the buckle plate 11, as Figure 4 shown.

[0024] The mandibular fixation member 20 includes a bottom plate 21 and a side plate 22; the bottom plate 21 and the side plate 22 are integrally connected together to form an "L" shape, as Figure 5 、 6As shown. The mandibular fixation member 20 is used to be fixed outside the oral cavity of the subject. The bottom plate 21 is located on the lower side of the mandible on the side where the surgical tooth is located, and the side plate 22 abuts against the outside of the mandible on the side where the surgical tooth is located; a first insertion hole 24 is formed on the side plate 22 along the up-down direction; the lower part of the insertion rod 12 is inserted and fixed in the first insertion hole 24. The first insertion hole 24 may be slightly larger than the insertion rod 12. It can provide a margin for adjusting the relative position between the dentition fixation member 10 and the mandibular fixation member 20.

[0025] The first end of the soft tissue traction and fixation member 30 can be adjustably fixed on the mandibular fixation member 20. The second end of the soft tissue traction and fixation member 20 is used to extend into the oral cavity of the subject to press the incised and dissected gingival soft tissue flap, so as to realize the traction and fixation of the gingival soft tissue flap.

[0026] A first threaded hole 25 is formed on the side plate 22 of the mandibular fixation member 20; a first bolt is installed in the first threaded hole 25, and the end of the first bolt abuts against the insertion rod 12 to fix the insertion rod 12 in the first insertion hole 24.

[0027] The soft tissue traction and fixation member 30 includes a pressing rod; the pressing rod includes a first section 31a, a second section 31b, a third section 31c and a fourth section 31d, as Figure 7 、 8 shown.

[0028] The first section 31a is perpendicular to the second section 31b; the second section 31b is used to abut against the corner of the subject's mouth and extend into the oral cavity of the subject from the outside.

[0029] The third section 31c is perpendicular to the second section 31b; the third section 31c and the first section 31a are respectively located at both ends of the second section 31b; the third section 31c extends downward along the inner side of the cheek in the oral cavity of the subject to reach the surgical tooth.

[0030] The fourth section 31d and the second section 31b are respectively located at both ends of the third section 31c; the fourth section 31d forms an obtuse angle with the third section 31c, such as 135 degrees; the fourth section 31d is used to press the gingival soft tissue flap through its lower side.

[0031] As Figure 9 shown, the lower side of the fourth section 31d is formed as an inclined surface, and the edge close to the surgical tooth is located above the side of the edge far from the surgical tooth. The inclined surface is more conducive to pulling the gingival soft tissue flap. As Figure 8 shown, a plurality of parallel convex ribs are formed on the lower side of the fourth section 31d along its extending length direction, and the convex ribs can increase the friction between the inclined surface and the gingival soft tissue flap.

[0032] The soft tissue traction fixing member 30 further includes a connecting member 32; the first end of the connecting member 32 forms a second jack 32b; the first section 31a of the pressing rod is inserted into the second jack 32b, and the second jack 32b can be formed with a relatively larger width than the first section to provide a margin for adjusting the position of the pressing rod in the oral cavity; a second threaded hole is formed in the first end of the connecting member 32, and a second bolt 33 is installed in the second threaded hole; the end of the second bolt 33 abuts against the first section 31a of the pressing rod to fix the first section 31a of the pressing rod in the second jack. By loosening the second bolt 33, the position of the pressing rod extending into the subject's oral cavity can be adjusted.

[0033] The second end of the connecting member 32 forms a third through hole 32a.

[0034] A cylinder 23 extends upward on the side plate 22 of the mandibular fixing member 20, and the connecting member 32 of the soft tissue traction fixing member 30 is sleeved on the cylinder 23 through its third through hole 23a.

[0035] External threads are formed on the upper part of the cylinder 23; a nut 35 is installed on the upper part of the cylinder 23; a solenoid compression spring 34 is installed around the cylinder 23 at the lower part of the cylinder 23; the upper end of the solenoid compression spring 34 supports on the lower side of the connecting member 32, and the nut 35 presses on the upper side of the connecting member 32, as Figure 11 shown. By adjusting the position of the nut 35, the height position of the fourth section 31d in the oral cavity can be adjusted to facilitate adjusting the pulling force of the fourth section on the gingival soft tissue flap.

[0036] During use, first, according to the position of the surgical tooth, install the buckling plate at an appropriate position in the dental arch, and the lower side of the buckling plate can be adhesively fixed to the dental arch; then insert the inserting rod into the first jack of the mandibular fixing member, and then fasten the inserting rod with the first bolt so that the dental arch fixing member and the mandibular fixing member are stably installed on the patient's dental arch and mandible. Adjust the depth of the pressing rod inserted into the oral cavity through the second bolt 33 so that the fourth section of the pressing rod is at an appropriate position near the surgical tooth. Rotate the nut so that the pressing rod moves downward, and the fourth section presses on the gingival soft tissue flap to perform traction on the incised and dissected gingival soft tissue flap, so that the surgical area is better exposed and the smooth progress of the operation is facilitated.
