Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of internal retractor for cervical spine surgery, to solve the problem of the pulling force of the medical staff in the process of pulling the tissue when the existing retractor is used to pull the tissue in the front of the cervical spine mentioned in the background technology. The size is subjective, and it is easy to cause problems such as excessive tissue tearing and iatrogenic injury

Embodiment 1

[0019] Example 1: See figure 1 with figure 2 , the present invention provides a technical solution: a medial retractor for cervical spine surgery, including a pulling body arranged in the area of ​​the cervical spine to be operated; Both ends of the pulling main body are rotatably connected with wing plates 2, and a chute matching the exposed end of the vertebral expansion screw 1 is provided on the wing plate 2, and the wing plate 2 slides Connected to the corresponding vertebral body expansion screw 1, the pulling body rotates and pokes away the tissue in the area to be operated, exposing the operation field.

[0020] In order to manipulate the pulling body more conveniently, a handle 6 is also arranged on the pulling body, one end of the handle 6 is fixed on the pulling body, and the other end extends out of the area to be operated; the pulling body Driven by the handle 6 to rotate or move up and down.

[0021] The pulling body is a pulling plate 4, and the pulling plat...

Abstract

The invention discloses an inner-side retractor for cervical vertebra surgery. The retractor comprises a main traction body arranged in a surgical area of the cervical vertebra and two vertebral bodyspreading screws correspondingly placed in two adjacent vertebral bodies of the cervical vertebra; wing plates are rotatably connected with the two ends of the main traction body, provided with sliding grooves matched with the exposed ends of the vertebral body spreading screws and slidingly connected to the corresponding vertebral body spreading screws; the main traction body rotates and pushes the tissue of the surgical area aside to expose a surgical field. The length of a traction plate is determined by the height of the vertebral bodies of the cervical vertebra in the surgical area, the contact area of the traction plate and the tissue can be increased, and therefore the situation is avoided that iatrogenic injuries are caused when the important tissue (esophagus, trachea, arteries and veins) easily expands out.

Description

technical field [0001] The invention relates to an auxiliary appliance for cervical spine surgery, in particular to an inner drag hook for cervical spine surgery. Background technique [0002] In cervical spine surgery, in order to expose the affected part and carry out local operation and treatment, it is necessary to use vertebral body distraction screws and vertebral body distractors to distract the adjacent vertebral bodies, and cooperate with retractors to pull and protect the tissues at the front of the cervical spine, for example: Esophagus, trachea, carotid artery, jugular vein, etc. Existing retractors are often made of curved plates. During the process of pulling the front tissue of the cervical spine, the following problems are prone to occur: 1) The width of the existing retractors is narrow, and important tissues and arteries are easy to expand from both sides of the retractors. iatrogenic injury, such as esophageal fistula, tracheal fistula, and carotid artery...
