Description

Technical Field

[0001] The present invention relates to the technical fields of maxillofacial surgery and orthodontics, and particularly to a slot-type intermaxillary traction assistor for the upper and lower dental arches. Background Art

[0002] Currently, in the fields of maxillofacial surgery and orthodontics, for the treatment of different degrees of malocclusion caused by congenital or acquired factors, it may involve applying orthodontic force with a rubber band using a single tooth, a local dental arch segment, or an implanted anchorage button as the anchorage at a small scale, and may also involve applying a greater force to elastically traction the jawbone using the entire upper or lower dental arch as the anchorage at a large scale. Especially after orthognathic surgery for dentofacial deformities and after jaw fracture surgery, due to the inability of muscles, ligaments, fascia, etc. to adapt to the instantaneous changes in the bone structure, the pulling force of soft tissues is likely to cause the bone structure to relapse towards the original deformed structure. Therefore, the intermaxillary traction after operations such as vertical, Class II, Class III, and oblique types between the upper and lower jaws is particularly important. Through reliable traction for four to six weeks, stable mesiodistal, left-right, and vertical relationships are maintained between the dental arches or the jaws, providing a basis for the postoperative reconstruction and balance of soft tissues such as the muscle system, and ultimately achieving a stable functional health, coordination, and even a beautiful appearance.

[0003] Intermaxillary elastic traction usually requires selecting a rubber band with an appropriate diameter and force. Starting from a certain one or a group of traction hooks or anchorage buttons (traction sites) on the upper or lower jaw, according to different surgical types and the directions of opposing muscles, passing through one-way or two-way, straight or broken lines, box-shaped or triangular, etc., and hanging to the target position, the resilience formed after the rubber band is stretched is the traction force that needs to be utilized. On the third day after the operation, the intermaxillary traction will be completed under the guidance of a doctor. After teaching the patient or family member, within the time from discharge to six weeks after the operation, the patient or family member must replace the rubber band three times a day by themselves.

[0004] In summary, it is particularly important to ensure that the patient or family member can perform traction correctly and effectively for the postoperative effect.

[0005] Currently, the commonly used intermaxillary traction assistor is a medical vascular forceps (10 cm or 12 cm). Although doctors can operate it skillfully, patients and their family members have reported through practice that they cannot use the vascular forceps for intermaxillary traction efficiently. The problems and reasons are summarized as follows:

[0006] 1. The mouth opening degree is small after the operation, and the visual field and operating space are small;

[0007] 2. The soft tissues are still swollen after the operation, and the surgical incision has not completely healed, increasing the operation difficulty;

[0008] 3. The traction sites are usually set in the canine area and the molar area. The molar position is relatively posterior, close to the surgical incision, with a small operating space and a poor visual field. The fear of patients or their family members also increases the operation difficulty;

[0009] 4. The medical vascular forceps is a right-handed instrument, and the opening and closing of the vascular forceps during operation require high skills from the operator, with relatively high operation difficulty.

[0010] 5. The vascular forceps may accidentally clamp the oral mucosal soft tissue.

[0011] 6. Due to the inconsistent physiological curvature of the alveolar bone and the curvature of the vascular forceps, the operation difficulty varies at different operation sites.

[0012] 7. The inner side of the front end of the vascular forceps is serrated. If the force is too large, it may increase the risk of accidental disconnection of the rubber band.

[0013] 8. The top end of the vascular forceps is blunt, making it difficult to hold the rubber band with one hand, resulting in a time-consuming and laborious operation process. Summary of the Invention

[0014] The technical problem to be solved by the present invention is to provide a slot-type intermaxillary traction assistor for the upper and lower dental arches. The traction assistor is designed in terms of appearance and function, simplifies the operation complexity of traditional vascular forceps, improves operation efficiency, can conveniently hold the rubber band, and is more ergonomic and effective in the traction process; the traction is time-saving and labor-saving; it is convenient for doctors, patients and their families to operate and is easy to promote.

[0015] The technical solution adopted by the present invention to solve its technical problems is: to provide a slot-type intermaxillary traction assistor for the upper and lower dental arches, including a traction assistor body. The traction assistor body includes a connecting part, a holding part and a clamping part connected in sequence. Two holding parts are installed at the end of the connecting part. The connecting part and the two holding parts form a "human" shaped structure as a whole. One end of each holding part is connected with a clamping part, and a plurality of clamping protrusions are arranged side by side on the outer side of the free end of the clamping part.

[0016] As a supplement to the technical solution of the present invention, the clamping part includes a flat part and a pointed part. One end of the flat part is connected with the holding part, and the other end of the flat part is connected with the pointed part. The flat part and the pointed part form a V shape as a whole, and the clamping part and the holding part form a spoon-shaped structure as a whole.

[0017] As a supplement to the technical solution of the present invention, the included angle between the flat part and the holding part ranges from 150 degrees to 160 degrees.

[0018] As a supplement to the technical solution of the present invention, the included angle between the flat part and the pointed part ranges from 110 degrees to 130 degrees.

[0019] As a supplement to the technical solution of the present invention, the clamping protrusion is cylindrical, one end of the clamping protrusion is fixed to the outer side wall of the clamping portion, and the other end of the clamping protrusion is hemispherical.

[0020] As a supplement to the technical solution of the present invention, the connecting portion, the holding portion and the clamping portion are integrally formed.

[0021] As a supplement to the technical solution of the present invention, two clamping protrusions are arranged side by side on the outer side of the free end of the clamping portion.

[0022] As a supplement to the technical solution of the present invention, the end of the free end of the clamping portion is hemispherical.

[0023] Beneficial effects: The present invention relates to a slot-type intermaxillary traction assistor for the upper and lower dental arches. The traction assistor is designed in terms of appearance and function, simplifies the operation complexity of the traditional hemostatic forceps, improves the operation efficiency, can not only conveniently clamp the rubber band, but also be more ergonomic and more effective in traction during the traction process; the traction saves time and effort; it is convenient for doctors, patients and their families to operate and is easy to promote.
