Embodiment 1

[0031] like Figures 1~3 Among them, an auxiliary fixator for maxillofacial surgery includes an elastic support plate 2, the elastic support plate 2 adopts an elastic steel sheet coated with silica gel externally, and the two ends of the elastic support plate 2 are provided with a tooth seat 1, and the tooth seat 1 is provided with a tooth seat 1. There is a tooth connection sleeve 101, the tooth connection sleeve 101 is an elastic metal curved surface structure, and the tooth connection sleeve 101 is used to cover the outer wall of the teeth. When in use, the two tooth connection sleeves 101 are respectively used to connect with the teeth of the upper jaw and the lower jaw of the oral cavity, The elastic struts 2 are located in the oral cavity and are bent distally to the buccal side. With this structure, the interference of the elastic support plate 2 to the surgical operation and the obstructing of the field of vision of the operating doctor are both small.

Embodiment 2

[0037] There have been many cases of patients suffocating due to poor drainage during surgery. There are more cases of pulmonary infection, but it is difficult to prevent fluid from entering the airway during transoral surgery. The current measures are mainly to prevent fluid from entering the airway through a drainage tube, but there is still a great risk of omission. This problem has not been solved, and the preferred solution is as follows figure 2 , 3 , 5, 6, there is also a liquid blocking bag 4, the liquid blocking bag 4 is connected with the elastic support plate 2, and the liquid blocking bag 4 is used for sticking to the inside of one side of the gum to prevent liquid from entering the airway. The liquid barrier bag 4 is provided with a bag body hook 45 extending upward. The bag body hook 45 adopts a twisted structure, hangs on the elastic support plate 2, and is fastened with a buckle structure. Preferably, the bag body hook 45 is a structure in the same direction....

Embodiment 3

[0043] In the preferred solution as in 3, a cheek support 3 is also provided, and the cheek support 3 is provided with a cheek elastic support plate 31, the cheek elastic support plate 31 is bent toward the cheek side, and the two ends of the cheek elastic support plate 31 are connected to the connecting seat 102 or the tooth connecting sleeve 101 are connected in a detachable manner; the cheek elastic support plate 31 is connected with the connecting seat 102 or the tooth connecting sleeve 101 by snap connection or screw connection. For example, a ball head is provided on the back of the connection seat 102 or the tooth connection sleeve 101, and a cross hole is provided on the cheek elastic support plate 31, and the cross hole is clamped to the ball head. For another example, elastic buckles are provided at both ends of the cheek elastic support plate 31 , and the elastic buckles are directly clamped on the connecting seat 102 or the tooth connecting sleeve 101 after being op...

Abstract

The invention provides a maxillofacial surgery auxiliary fixator which comprises an elastic supporting plate, tooth bases are arranged at the two ends of the elastic supporting plate, tooth connecting sleeves are arranged on the tooth bases, the tooth connecting sleeves are used for covering the outer walls of teeth, and during use, the two tooth connecting sleeves are used for being connected with the teeth of the upper jaw and the lower jaw of the oral cavity respectively; the elastic supporting plate is located in the oral cavity and is bent towards the far cheek side. Through the arrangement of the structure of the elastic supporting plate and the tooth base, and the elastic supporting plate is located in the oral cavity and bent towards the far buccal side, the effects of fixing the posture of the oral cavity, not obstructing operation and reducing shielding can be achieved. In a preferable scheme, the cheek support can support the cheek in a non-invasive mode, and the position of the cheek support can be conveniently adjusted.

Description

technical field [0001] The invention relates to the field of maxillofacial surgical instruments, in particular to an auxiliary fixer for maxillofacial surgery. Background technique [0002] During maxillofacial surgery, such as oral and maxillofacial tumor surgery and gum surgery, an intraoral submaxillary incision is required, and the oral cavity needs to be kept open during the operation. The existing auxiliary fixator usually requires medical staff to hold the fixator while performing surgical operations, such as CN209404983U. In order to overcome this technical problem, the prior art adopts a fixed improved solution, such as an easy-to-operate distraction device for oral and maxillofacial surgery described in CN 215306228U, but the structure is too complicated and the operation is inconvenient. Also CN202221U describes an arc-shaped adjustable oral spacer, which has a relatively simple structure, but the arc-shaped support frame is located outside the oral cavity. Altho...
