Problems solved by technology

This requires higher accuracy and greater difficulty in positioning the pedicle. In the process of positioning and surgery, it is necessary to repeatedly activate X-rays to correct and determine the position and direction of the pedicle channel. People and patients have caused greater harm. Even if the pedicle channel is established in this way, it often cannot reach the ideal position and direction, which will affect the effect of the operation.

Embodiment 1

[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention has a sticker 1 with two positioning terminals 12 on the sticker 1. The positioning terminals 12 are located at both ends of the sticker 1. The positioning terminals 12 and the sticker 1 are fixed together. There are assembly holes, and fastening screws 4 are also installed on the positioning terminal 12; a longitudinal slideway 3 is installed on the positioning terminal 12, and the longitudinal slideway 3 is installed on the positioning terminal 12 through the bracket 2, and the bracket There is a fixed shaft on 2, the fixed shaft is installed in the assembly hole of the positioning terminal 12, and is tightened and fixed with the fastening screw 4, and the interference fit is adopted between the longitudinal slideway 3 and the bracket 2, and the two are fixed; A horizontal slideway 5 is installed on the longitudinal slideway 3, and a fastening screw 6 is ...

Embodiment 2

[0022] Such as Figure 7 , Figure 8 and Figure 9 As shown, its structure is as embodiment 1, and the only difference is that a lateral rotation positioning head 19 is installed on the positioning seat 7, and the connecting shaft on the lateral rotation positioning head 19 is connected with the connecting hole on the positioning seat 7. There is a transition fit between them, that is, when a small force is applied on the laterally rotating positioning head 19, the laterally rotating positioning head 19 cannot rotate, and when a large active force is applied, the laterally rotating positioning head 19 can rotate, so as to prevent It rotates in the process of operation; On the horizontally rotating positioning head 19, a longitudinally rotating positioning block 20 is installed, a connecting shaft is arranged on the longitudinally rotating positioning block 20, a connecting hole is arranged on the horizontally rotating positioning head 19, and the vertically rotating positioni...

Abstract

The invention discloses a multifunctional percutaneous vertebral pedicle positioning apparatus which is provided with a sticker. Two positioning terminals are arranged on the sticker, longitudinal slide rails are mounted on the positioning terminals, transverse slide rails are mounted on the longitudinal slide rails, a positioning seat is mounted on the transverse slide rails, a transverse rotary positioning head is mounted on the positioning seat, a longitudinal rotary mounting block is mounted on the transverse rotary positioning head, and a mounting positioning needle is arranged on the longitudinal rotary positioning block. The multifunctional percutaneous vertebral pedicle positioning apparatus has the advantages that a needle point of the positioning needle can be adjusted in the longitudinal direction and the transverse direction, spatial angles of the positioning needle can be adjusted in the longitudinal direction and the transverse direction, accordingly, the directions of the positioning needle can completely coincide with the directions of set vertebral pedicle channels, noninvasive positioning effects can be realized, and requirements of needle insertion channels at different angles can be met; quick and accurate positioning effects can be realized, the multifunctional percutaneous vertebral pedicle positioning apparatus is convenient to adjust, only 2-3 times of X-ray examination are required in a positioning procedure, and accordingly the multifunctional percutaneous vertebral pedicle positioning apparatus is little in harm to medical staffs and patients, can be used for surgery on various segments of the lumbar vertebras and the thoracic vertebras of the patients and also can be used for establishing articular process plasty channels for intervertebral endoscopic foramen mirrors.

Description

technical field [0001] The invention belongs to a medical appliance, in particular to a multifunctional percutaneous pedicle positioner used in orthopedic surgery. Background technique [0002] In clinical practice, orthopedic surgeons will encounter a variety of spinal disorders, such as herniated disc, spinal stenosis, scoliosis, spinal fractures, tuberculosis and tumors, etc. During the surgical treatment of these diseases, it is necessary to drill holes through the pedicle or implant screws for fixation or correction, or compress the vertebral body through the pedicle to expand and expand, and inject bone cement to treat vertebral body compression fractures. The establishment of the pedicle channel is crucial to the success of the operation. When establishing a pedicle channel, the position and direction of establishing the pedicle channel should be determined first. At present, there are mainly two methods for establishing the position and direction of the pedicle cha...
