Problems solved by technology

[0002] In the prior art, the occipital cervical internal fixation device is generally used for the internal fixation of the first cervical vertebra fracture, but the structure of the device is complex and the operation is cumbersome, especially the head and cervical spine need to be fixed, the surgical trauma is large, the risk is high, and it is easy to cause complications
Furthermore, the movement of the head and neck of the patient is severely restricted after the operation, which brings a lot of inconvenience to the patient's work and life.
Moreover, the device cannot directly reduce and fix the fractured first cervical vertebra.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0019] Referring to Fig. 1 and Fig. 2, the present invention includes a transverse connecting rod 2 corresponding to the arcuate shape of the first cervical vertebra 1 of the human body. The middle section 2.1 of the horizontal connecting rod 2 is flat to adapt to and fit the back arch of the first cervical vertebra 1, and extends from the middle section to both ends 2.2 to gradually transition to a cylindrical shape. The shape can be a cylinder, or a triangular prism, or a polygonal prism such as a quadrangular prism. The two ends 2.2 of the horizontal connecting rod enter into the straight groove 3.1 of the fixed rod 3 provided with a universal joint, and are fixedly connected with it. The front end of the fixing rod 3 is provided with a screw 3.2 which can be fixedly connected with the first cervical vertebra 1 of the human body.

Abstract

A first cervical vertebra rear way internal fixation device is characterized by : It includes a cross connecting link which is corresponding with the human body first cervical vertebra bone rear arcuate, the middle part of said cross connecting link is flat to meeting and applying the first cervical vertebra rear arcuate and extends to two ends transiting to cylindrical shape gradually, the two ends insert into straight flute of fixed rod equipped with universal-joint and is connected with the fixed rod immoveable, the front end of said fixed rod is equipped with screw which is connected with the human body first cervical vertebra said bone immoveable.The present invention overcomes the shortage of treating first cervical vertebra bone fracture rear way fixation device in prior technology. The invention reveals the first cervical vertebra when applying it, the surgical incision is small and wounds are light; due to it fixes the first cervical vertebra only, it maintains the activities of pillow neck and cervical vertebra, while resets directly and fixes bone fracture.

Description

【Technical field】 [0001] The invention relates to a medical instrument for treating human cervical spondylosis, in particular to a posterior internal fixation device for the first cervical vertebra. 【Background technique】 [0002] In the prior art, an occipital cervical internal fixation device is generally used for the internal fixation of the first cervical vertebra fracture, but the structure of the device is complex and the operation is cumbersome, especially the head and cervical spine need to be fixed, the surgical trauma is large, the risk is high, and it is easy to cause complications. Furthermore, the movement of the head and neck of the patient is severely restricted after the operation, which brings a lot of inconvenience to the patient's work and life. Moreover, this device cannot directly reduce and fix the fractured first cervical vertebra. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the above-me...
