[0002] In recent years, with the advancement of science and technology and the continuous improvement of people's living standards, the incidence of intracranial injuries and cerebrovascular diseases has continued to increase, and the number of craniomaxillofacial surgeries has increased year by year. The craniomaxillofacial region is divided into the maxilla and mandible. The maxilla is the bone plate between the nasal cavity and the oral cavity, and the mandible refers to the chin. Together, they form the craniomaxillofacial region.

[0003] In craniomaxillofacial orthopedic surgery, it is usually necessary to use a craniomaxillofacial plate system to fix the craniomaxillofacial bone fracture site. However, the structure of the craniomaxillofacial region varies from person to person. Even though there are many types of plates, it is difficult to adapt to the needs of various complex structures. In actual applications, the plates need to be shaped and cut to adapt to the attachment of facial bones. Currently, tools similar to scissors are generally used for cutting during surgery, but there are problems such as inconvenient shaping, unstable fixation, and narrow surgical field of view.

[0004] Therefore, providing a bending forceps for craniomaxillofacial surgery is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0009] Furthermore, support arms are provided on the inner sides of the two handles, one end of the support arms is fixedly connected to the handles, and the other end of the support arms is cross-hinged.

[0010] Furthermore, the clamp includes a cutting section and a shaping section connected to each other, the two ends of the cutting section are respectively connected to the handle and the shaping section, the cutting edge is arranged on the cutting section, the cylinder and the matching groove are arranged on the shaping section, and the shaping section is bent toward the side.

[0011] Furthermore, the connecting line of the two ends of the shaping section and the two ends of the cutting section are connected to form an angle Φ, and the angle Φ is 20 to 40 degrees. ° .

[0012] Furthermore, an anti-slip layer is provided on the outer side of the handle.

[0013] Furthermore, a hook is arranged on the inner side of the end of one of the handles, and a ring matching with the hook is arranged on the inner side of the end of the other handle.

[0014] The beneficial effects of the utility model are as follows: the bending pliers used for craniomaxillofacial surgery of the utility model can stably clamp and fix the bone plate and reshape it by matching the cylinder with the circular hole of the craniomaxillofacial bone plate, which is easy to operate and ensures that the bone plate does not move relative to each other during shaping, and can also protect the circular hole on the craniomaxillofacial bone plate from deformation during bending, thereby not affecting the implantation and fixation of bone screws; the head clamp of the bending pliers is bent to one side, which can make the field of view wider when implanting the bone plate and facilitate surgical operation.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0027] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] The first embodiment provided by the utility model is as follows Figure 1As shown, the bending pliers mainly include a bending pliers body, which includes two pliers arms 100 hinged together, and the two pliers arms 100 are arranged crosswise with each other (similar to the shape of scissors). The pliers arms 100 include a clamp 120 and a handle 110 connected to each other, and a cylinder 123 is arranged on the inner side of the end of one clamp 120, and a matching groove 125 that can match the cylinder 123 is arranged on the inner side of the end of the other clamp 120. The craniomaxillofacial bone plate is generally provided with a through hole for fixing with a screw. During the surgical operation, when the clamp 120 of the bending pliers clamps the bone plate, the cylinder 123 passes through the through hole of the bone plate to firmly clamp the bone plate, which is convenient for surgical operation and shaping; at the same time, the cylinder 123 matches the through hole of the bone plate, and protects the through hole from deformation during bending, thereby not affecting its fixation.

[0030] like Figure 1 As shown, the inner sides of the two clamps 120 are symmetrically provided with cutting edges 124 below the cylinder 123, so that the bending pliers can not only clamp, fix and shape, but also cut the bone plate. The inner sides of the two handles 110 are provided with support arms 111, one end of the support arms 111 is fixedly connected to the bottom of the handles 110, and the other end is cross-hinged. Figure 2 and 3 As shown, a hook 112 is disposed on the inner side of the end of one of the handles 110 , and a ring 113 that can match the hook 112 is disposed on the inner side of the end of the other handle 110 .

[0031] Preferably, an anti-skid layer is provided on the outer side of the handle 110 to prevent hand-holding from slipping during surgical operations.

[0032] like Figure 3-5 The second embodiment provided by the utility model is shown, which is substantially the same as the first embodiment, except that the clamp 120 includes a cutting section 122 and a shaping section 121 connected to each other, the two ends of the cutting section 122 are respectively connected to the handle 110 and the shaping section 121, the cutting edge 124 is arranged on the cutting section 122, and the cylinder 123 and the matching groove 125 are arranged on the shaping section 121. The bending forceps body has two side surfaces 100a and 100b with the largest surface area, and the end of the clamp 120 away from the handle 110 (i.e., the shaping section 121) is bent toward any one of the side surfaces 100a of the bending forceps body. The bending structure of the head of the bending forceps in this embodiment can leave a wider field of view when the bending forceps are used to clamp and fix the bone plate in craniomaxillofacial surgery, which is convenient for surgical operation and shaping.

[0033] Preferably, a line connecting two ends of the shaping section 121 and a line connecting two ends of the cutting section 122 form an angle Φ, and the angle Φ is 20-40°.

[0034] In specific craniomaxillofacial surgery operations, the straight-head bending pliers of the first embodiment and the elbow bending pliers of the second embodiment can be used in combination. The straight-head bending pliers held in one hand are used to clamp and fix the bone plate, and the elbow bending pliers held in the other hand are used to shape or cut the bone plate. When used in combination, not only can the bone plate be firmly clamped, but also the field of vision is wide and the operation is convenient.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
