Compared with the prior art, the utility model greatly optimizes the operation of the upper cervical pedicle screw placement operation, reduces the operation risk and effectively protects the blood vessels, nerves and important tendon soft tissues of patients; the method helps an operator to determine pedicle screw placement points and establish screw placement channels, can effectively measure the pedicle screw implantation position, angle and depth of each vertebral body of the upper cervical vertebra during operation, and is convenient for selecting an adaptive screw; the attaching surface and the channel of the guide plate can well protect tissues around the vertebral body from being damaged, and the safety of complex operations is improved.

Description

Cervical vertebra nail-placing guide plate

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a cervical vertebra nail-placing guide plate.

Background

The cervical vertebra of a person is formed by connecting 7 cervical vertebrae, ligaments, joints and intervertebral discs, cervical vertebra fracture refers to Li Ai women's first name and integrity interruption of the cervical vertebra under the action of certain factors, the cervical vertebra fracture is divided into injury cervical vertebra fracture and lower cervical vertebra fracture according to different fracture parts, the former comprises 1 st and 2 nd cervical vertebra fracture, the latter comprises 3 rd to 7 th cervical vertebra fracture, the cervical vertebra fracture needs to be subjected to pedicle screw placement operation, the conventional screw placement operation is usually performed according to clinical experience of doctors, the accuracy of the operation cannot be guaranteed and cannot be popularized in a large scale, and therefore, the cervical vertebra screw placement guide plate is developed and developed, and the accuracy of the operation is very necessary.

Disclosure of Invention

The utility model aims to provide a cervical vertebra nail-placing guide plate.

The utility model aims to realize that the cervical vertebra nail-placing guide plate comprises an attaching surface and a hand-held handle, wherein a first positioning channel and a second positioning channel are respectively arranged on two sides of the attaching surface, the hand-held handle is arranged on the opposite surface of the attaching surface, and the hand-held handle is of a U-shaped structure and is respectively connected with the first positioning channel and the second positioning channel.

Compared with the prior art, the utility model has the following advantages and effects:

1. greatly optimizing the operation of the upper cervical pedicle screw placement operation, reducing the operation risk and effectively protecting the blood vessels, nerves and important tendon soft tissues of a patient;

2. the method helps an operator to determine pedicle screw placement points and establish screw placement channels, can effectively measure the pedicle screw implantation position, angle and depth of each vertebral body of the upper cervical vertebra during operation, and is convenient for selecting an adaptive screw;

3. the attaching surface and the channel of the guide plate can well protect tissues around the vertebral body from being damaged, and the safety of complex operations is improved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings, without limiting the utility model in any way, and any alterations or substitutions based on the teachings of the utility model are intended to fall within the scope of the utility model.

As shown in the drawings, the utility model comprises an attaching surface 1 and a hand-held handle 2, wherein a first positioning channel 3 and a second positioning channel 4 are respectively arranged on two sides of the attaching surface 1, the hand-held handle 2 is arranged on the opposite surface of the attaching surface 1, and the hand-held handle 2 is of a U-shaped structure and is respectively connected with the first positioning channel 3 and the second positioning channel 4.

The attaching surface 1 is two independent surfaces and is respectively arranged at two ends of the hand-held handle 2, and the first positioning channel 3 and the second positioning channel 4 are respectively arranged on the attaching surface 1.

The two attaching surfaces 1 are arranged in opposite directions.

The working process of the utility model comprises the following steps:

1. exposing spinous processes and nail insertion points of the cervical vertebra in the operation, stripping bone surface muscles, completely attaching the attaching surface of the guide plate to the bone surface, and confirming that the guide plate positioning channel is not abnormal;

2. the left and right channels of the guide plate are respectively inserted into the pedicles at the left and right sides of the cervical vertebra by using a 2.0mm diameter Kirschner wire, a guide channel for implanting the subsequent pedicle screws into the vertebral body is established, and the length of the screws is confirmed;

3. and respectively withdrawing the Kirschner wires inserted into the left side and the right side of each vertebral body, taking out the cervical vertebra nail-placing guide plate, implanting the pedicle screw of the cervical vertebra, connecting the nail rod, and finally suturing.

While the present utility model has been described in detail with reference to the drawings, the scope of the utility model is not limited to the above embodiments, and various changes can be made by those skilled in the art without departing from the spirit of the utility model.
