Description

Technical Field

[0001] This utility model relates to the field of orthodontic forceps technology, specifically to an orthodontic forceps. Background Technology

[0002] Orthodontic forceps are a common tool used in orthodontic treatment. They are typically used during orthodontic treatment to remove, place, and replace archwires in the brackets of the upper and lower jaws. There are various types of orthodontic forceps, including right-angle forceps, curved forceps, and flat forceps.

[0003] For example, Chinese Patent Publication No. CN221154344U "discloses an orthodontic forceps for dental use, including two cross-arranged forceps arms, a fixed outer shell is sleeved on the outside of the intersection of the two forceps arms, and a placement groove is opened at the upper position of one side of the fixed outer shell";

[0004] In the aforementioned comparative document, the lighting lamp placed inside the placement slot can be moved out of the placement slot by pulling the connecting rod. This allows for direct illumination of the oral cavity during oral treatment, reducing the need for dentists to retrieve additional intraoral lighting equipment and making orthodontic work more convenient and efficient.

[0005] However, during use, the protruding part of the handle of the aforementioned orthodontic forceps is directly in the dentist's field of vision, which interferes with the patient's oral treatment and makes it difficult for the dentist to treat the open mouth. Furthermore, the fixed shell and the forceps head of the existing orthodontic forceps cannot be disassembled, making it impossible to disassemble and thoroughly clean and disinfect the forceps during disinfection. Utility Model Content

[0006] The purpose of this utility model is to provide an orthodontic forceps. This orthodontic forceps can adjust the protruding position of the forceps handle according to the angle of the patient's mouth during oral treatment, thereby avoiding obstruction of the mouth and making it more convenient for doctors to operate. At the same time, the fixed shell and the forceps head of the orthodontic forceps can be disassembled for easier cleaning and disinfection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an orthodontic forceps, comprising symmetrically arranged forceps frames and handles, a fixed outer shell, forceps heads, and a return spring. Each of the two forceps frames has an opening groove and an external thread near the handle. A pin is fixedly installed in the inner wall of the opening groove. A fastening sleeve is slidably fitted onto one end of the handle. A movable sleeve is fixedly connected to the end of the handle near the forceps frame. The fixed outer shell includes an upper shell and a lower shell. A central shaft is provided between the upper shell and the lower shell. Connecting sleeves are fixedly connected to the ends of the two forceps frames away from the handle. The two connecting sleeves are rotatably mounted on both sides of the outer surface of the central shaft. Positioning bolts are threadedly installed on the outer surfaces of the upper shell and the lower shell.

[0008] Preferably, the opening groove has a U-shaped structure, and the movable sleeves at the ends of the two sets of clamp handles are respectively rotatably mounted on the corresponding pins.

[0009] Preferably, both the end of the clamp handle and the interior of the fastening sleeve have a T-shaped structure, and the two sets of fastening sleeves are connected to the corresponding external threads by threads.

[0010] Preferably, bushings are rotatably mounted on the adjacent surfaces of the upper housing and the lower housing, and the two ends of the central shaft are respectively engaged in the two sets of bushings. The upper housing and the lower housing are fixedly mounted with fixing bolts by threads.

[0011] Preferably, the two sets of clamp heads are fixedly installed on the outer surfaces of the two sets of connecting sleeves.

[0012] Preferably, positioning holes are equally spaced on the outer circumference of the two sets of connecting sleeves, and positioning bolts are threaded onto the outer sides of the upper housing and the lower housing, with the positioning bolts engaging with the corresponding positioning holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The two sets of orthodontic forceps of this utility model are connected by the forceps handle and the return spring. When performing oral operations, the fastening sleeve thread between the forceps handle and the forceps frame can be disassembled, so that the two sets of forceps handles can be folded along both sides of the opening slot. This can prevent the protruding part of the forceps handle from facing the dentist's operating view and affecting the oral treatment.

[0015] In this utility model, the upper and lower shells of the orthodontic forceps fixing shell can be disassembled by fixing bolts, so that the central shaft connecting the two sets of forceps heads can be disassembled from the adjacent surface bushings of the upper and lower shells. This allows the two sets of forceps heads to be separated from the fixing shell. After the forceps heads are used for oral treatment of patients, the forceps heads can be fully exposed to disinfectant and disinfection box after the fixing shell is disassembled, which makes it more convenient to clean and disinfect the forceps heads.

[0016] In this invention, when the two sets of forceps are rotated outside the central shaft and operated inside the oral cavity via the connecting sleeve, they can be positioned by the positioning bolts and the corresponding positioning holes on the connecting sleeve. This allows for positioning of the two sets of forceps after they open, making it easier to position the forceps after the patient opens their mouth during treatment without having to hold the orthodontic forceps to position the forceps opening. This makes oral treatment more convenient for patients. Attached Figure Description

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an orthodontic forceps, including symmetrically arranged forceps frame 1 and forceps handle 2, as well as a fixed shell 3, forceps head 4, and a return spring 5. The two sets of forceps 1 are respectively provided with an opening groove 11 and an external thread 13 near the end of the forceps handle 2. A pin 12 is fixedly installed in the inner wall of the opening groove 11. A fastening sleeve 22 is slidably sleeved on one end of the forceps handle 2. A movable sleeve 21 is fixedly connected to the end of the forceps handle 2 near the forceps frame 1.

[0025] The fixed outer shell 3 includes an upper shell 31 and a lower shell 32. A central shaft 6 is provided between the upper shell 31 and the lower shell 32. Two sets of clamps 1 are respectively fixedly connected to the end away from the clamp handle 2 with connecting sleeves 7. The two sets of connecting sleeves 7 are respectively rotatably installed on both sides of the outside of the central shaft 6. Positioning bolts 72 are respectively threadedly installed on the outer surfaces of the upper shell 31 and the lower shell 32.

[0026] The two sets of forceps 4 in the orthodontic forceps cooperate with the reset spring 5 through the forceps 2. During orthodontic treatment, the fastening sleeve 22 between the forceps 2 and the forceps frame 1 can be disassembled, so that the two sets of forceps 2 can be folded along both sides of the opening slot 11. This can prevent the protruding part of the forceps 2 from facing the dentist's operating view and affecting the treatment of the expanded oral cavity.

[0027] The upper shell 31 and lower shell 32 of the orthodontic forceps fixing shell 3 can be disassembled by fixing bolt 33, so that the central shaft 6 connecting the two sets of forceps heads 4 can be disassembled from the adjacent surface bushings of the upper shell 31 and lower shell 32. This allows the two sets of forceps heads 4 to be separated from the fixing shell 3. After the forceps heads 4 are used for oral treatment of patients, the forceps heads 4 can be fully exposed to disinfectant and disinfection box by disassembling the fixing shell 3, which makes it more convenient to clean and disinfect the forceps heads 4.

[0028] When the two sets of forceps 4 rotate and expand to adjust the opening outside the central shaft 6 via the connecting sleeve 7, they can be positioned by the positioning bolt 72 and the corresponding positioning hole 71 on the connecting sleeve 7. This allows the position of the two sets of forceps 4 after opening to be positioned. After positioning, the dentist does not need to hold the orthodontic forceps to position the opening of the forceps 4 during the treatment process, but can position the patient after opening their mouth, which makes it more convenient to treat the patient's oral cavity.

[0029] The opening groove 11 has a U-shaped structure. The movable sleeves 21 at the ends of the two sets of forceps 2 are rotatably mounted on the corresponding pins 12. The ends of the forceps 2 and the inside of the fastening sleeves 22 are both T-shaped structures. The two sets of fastening sleeves 22 are connected to the corresponding external threads 13 by threads. When the two sets of forceps 4 cooperate with the forceps 2 and the forceps frame 1 to open the patient's mouth for treatment, the threads of the fastening sleeves 22 between the forceps 2 and the forceps frame 1 can be disassembled, so that the two sets of forceps 2 can be folded along both sides of the opening groove 11. This can prevent the protruding part of the forceps 2 from facing the dentist's operating view and affecting the treatment of the oral cavity.

[0030] In this structure, bushings are rotatably installed on the adjacent surfaces of the upper housing 31 and the lower housing 32. The two ends of the central shaft 6 are respectively engaged in the two sets of bushings. The upper housing 31 and the lower housing 32 are fixedly installed with fixing bolts 33 by threads. The two sets of pliers 4 are respectively fixedly installed on the outer surfaces of the two sets of connecting sleeves 7. The upper housing 31 and the lower housing 32 in the fixed outer shell 3 can be disassembled by fixing bolts 33, so that the central shaft 6 connected by the two sets of pliers 4 can be disassembled from the bushings on the adjacent surfaces of the upper housing 31 and the lower housing 32. This allows the two sets of pliers 4 to be separated from the fixed outer shell 3. After the pliers 4 are used for oral treatment of patients, the fixed outer shell 3 can be disassembled for thorough cleaning and disinfection.

[0031] The two sets of connecting sleeves 7 have positioning holes 71 at equal intervals on their outer circumferences. The upper housing 31 and the lower housing 32 are threadedly installed with positioning bolts 72. The positioning bolts 72 are connected to the corresponding positioning holes 71. When the two sets of pliers 4 rotate and expand their openings outside the central shaft 6 through the connecting sleeves 7, they can be positioned by the positioning bolts 72 and the corresponding positioning holes 71 on the connecting sleeves 7. This allows the position of the two sets of pliers 4 after opening to be positioned.

[0032] Working principle: When in use, the dentist can hold the orthodontic forceps and bring the two sets of forceps handles 2 together to compress the reset spring 5. At this time, the two sets of forceps heads 4 can expand. The rubber sleeves on the outside of the two sets of forceps heads can then be used to position the upper and lower teeth of the patient's mouth. Then, the positioning bolts 72 can be installed and positioned with the positioning holes 71 on the corresponding connecting sleeves 7. This allows the position of the two sets of forceps heads 4 after opening to be positioned, making it convenient to position the patient after opening their mouth.

[0033] During oral treatment of patients, the two sets of forceps 4 in the orthodontic forceps cooperate with the reset spring 5 through the forceps handle 2. When the patient opens their mouth, the fastening sleeve 22 between the forceps handle 2 and the forceps frame 1 can be unscrewed, so that the two sets of forceps handle 2 can be folded along both sides of the opening slot 11. This can prevent the protruding part of the forceps handle 2 from facing the doctor's operating view and affecting the treatment of the wide-open mouth.

[0034] When cleaning and disinfecting the orthodontic forceps, the upper shell 31 and lower shell 32 of the fixed outer shell 3 can be disassembled by the fixing bolts 33, so that the central shaft 6 connecting the two sets of forceps heads 4 can be disassembled from the adjacent bushings of the upper shell 31 and lower shell 32. This allows the two sets of forceps heads 4 to be separated from the fixed outer shell 3. After the forceps heads 4 are used for oral treatment of patients, the forceps heads 4 can be fully exposed to disinfectant and disinfection box after the fixed outer shell 3 is disassembled, making it more convenient to clean and disinfect the forceps heads 4.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
