Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for reducing zygomatic bone and zygomatic arch fractures. Background Technology

[0002] The zygomatic bone is a quadrilateral bone located in the midface, closely connected to the maxilla, temporal bone, sphenoid bone, and frontal bone. It plays a vital role in protecting the eye socket and its contents, and in maintaining the midface contour. However, due to its prominent position, it is susceptible to fracture from impacts. Fractures can occur at the junctions of these bones. Under the influence of impact force, the fractured fragments often shift downwards, backwards, or inwards. Significant displacement of the fractured fragments can lead to facial collapse, deformities, and other issues, affecting not only facial aesthetics but also functional impairment.

[0003] Currently, the traditional method for reducing zygomatic bone fractures involves making an incision in the intraoral vestibule, bluntly inserting a periosteal elevator into the displaced medial part of the zygomatic bone, and using a levering method to reduce the fracture fragments. However, this method is prone to causing vascular and nerve damage when the periosteal elevator is used to separate and pry into the medial part of the zygomatic bone, leading to severe bleeding or nerve damage. Furthermore, the fracture fragments cannot be reduced in three dimensions. Simply prying from the posterior part of the fracture fragment can only move it forward, but cannot move it upward, downward, or laterally in three dimensions, resulting in incomplete reduction of the fracture fragments and postoperative facial deformity. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a zygomatic bone and zygomatic arch fracture reduction device, comprising: a connector; a reduction member, wherein the reduction member is detachably connected to the connector and the reduction member is used to displace the zygomatic bone; and a handle, wherein the handle is connected to the end of the connector away from the reduction member and the handle is used to control the movement of the connector and the reduction member.

[0005] As a further description of the above technical solution: the reset component includes a reset hook, and the reset hook is detachably connected to the connector.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Please see Figure 1-5 The present invention provides a technical solution: the zygomatic bone and zygomatic arch fracture reduction device of the present invention includes: a connector 1; a reduction component 2, the reduction component 2 being detachably connected to the connector 1, the reduction component 2 being used to displace the zygomatic bone; and a handle 3, the handle 3 being connected to the end of the connector 1 away from the reduction component 2, the handle 3 being used to control the movement of the connector 1 and the reduction component 2.

[0027] In this embodiment, the connector 1 and the repositioning component 2 are detachably connected. When the zygomatic bone or zygomatic arch is fractured, the corresponding repositioning rod 5 or repositioning hook 4 can be installed on the connector 1 to pull and traction the displaced fracture segment. The displaced fracture segment can be moved in various directions in three-dimensional space to achieve anatomical reduction. The connector also has a handle to hold, which can control the magnitude of the repositioning force.

[0028] like Figure 1 and Figure 4 As shown, specifically, the reset component 2 includes a reset hook 4, which is detachably connected to the connector 1. The reset hook 4 is provided with a first thread 41, which is adapted to the threaded hole 6. One end of the reset hook 4 is provided with a hook tip 42, and the other end is cylindrical.

[0029] In this embodiment, when the zygomatic arch is fractured, a 0.3m incision is made along the facial skin lines at the lower edge of the zygomatic arch fracture depression using a No. 1 sharp blade. The skin and subcutaneous tissue are cut open, and the reduction hook 4 of the reduction device is screwed into the connector 1 through the first thread 41 and tightened. Through this incision, the tip of the reduction hook is slowly inserted into the fracture fragment in an arc shape, close to the lower edge of the zygomatic arch and the inner bone surface. The right hand holds the handle 3 and pulls upward, forward, or downward according to the displacement of the fracture fragment. At the same time, the fingers of the left hand are placed on the skin of the displaced zygomatic arch fracture fragment to feel the reduction of the fracture fragment and to prevent excessive traction. Generally, the sound of the fracture fragment shifting can be heard during reduction. After the reduction is completed, the reduction hook 4 is withdrawn, and the skin incision is sutured with one stitch to complete the operation.

[0030] like Figure 2 and Figure 5 As shown, specifically, the reset component 2 includes a reset rod 5, which is detachably connected to the connector 1. The reset rod 5 is provided with a second thread 51, which is adapted to the threaded hole 6. One end of the reset rod 5 is provided with a self-tapping thread 52, and the other end is cylindrical.

[0031] In this embodiment, when the zygomatic bone complex is fractured, CT images are taken preoperatively, the most prominent point on the zygomatic bone surface is selected, the bone height and the soft tissue thickness from the bone surface to the skin surface are measured, and the expected depth of the reduction device is calculated. During the operation, a routine incision is made to expose the fracture sites of the zygomatic bone that need to be fixed, and the zygomatic bone is pried along the fracture suture to make it in a mobile state. A No. 1 sharp blade is used to make an incision of about 0.3m in length at the most prominent point on the zygomatic bone surface along the direction of facial skin lines, cutting through the skin and subcutaneous tissue. The reduction rod 5 of the reduction device is screwed into the connector 1 through the second thread 51 and tightened. One end of the self-tapping thread 52 is slowly screwed into the zygomatic bone through the small facial incision, and the scale marked on the reduction rod 5 is observed until it enters the predetermined depth. The right hand holds the handle 3 and moves it in three-dimensional space upward, downward, forward and backward according to the direction of zygomatic bone displacement, and the reduction of the fracture suture is observed until three-dimensional space reduction is achieved. The traction is maintained, and strong internal fixation is performed at each fracture suture. After the operation, the reduction rod 5 is removed, and the skin incision is sutured with one stitch.

[0032] like Figure 1 and Figure 3 As shown, specifically, the connector 1 has a threaded hole 6 inside, and the connector 1 is detachably connected to the reset component 2 through the threaded hole 6; the threaded hole 6 facilitates the replacement of the reset rod 5 and the reset hook 4.

[0033] like Figure 1 and Figure 2 As shown, specifically, the handle 3 is elliptical cylindrical, and the connector 1 is cylindrical.

[0034] Working principle: The connector 1 and the repositioning component 2 are detachably connected. When the zygomatic bone or zygomatic arch is fractured, the staff can install the corresponding repositioning rod 5 or repositioning hook 4 on the connector 1 to hook and pull the displaced fracture segment. The displaced fracture segment can be moved in all directions in three-dimensional space to achieve anatomical reduction. There is also a handle to hold, which can control the magnitude of the repositioning force.
