Abstract
The utility model discloses an orthopedics percutaneous pedicle of vertebral arch screw is put into art and is used accurate positioner, include and do not pass through the X line, but the disinfection of high temperature high pressure, and the compatible square board of biology has, the square board comprises the square strip of specifications such as ten lines, every line the square strip comprises the square of specifications such as seven, solitary differentiation character has been made to an organic whole in the square, square board length is 10mm, and the width is 8mm, and thickness is 2mm. The utility model discloses an orthopedics percutaneous pedicle of vertebral arch screw is put into art and is used accurate positioner at the in -process of operation, not only can effectively reduce perspective number of times in the art to reducing medical personnel and the contact of patient's ray volume, can shortening operation and anesthesia time moreover greatly, reduce patient's life safety hidden danger, while this device easy operation is in clinical easy popularization.
Description
Technical field
This utility model relates to a kind of percutaneous cervical arc root screw and inserts with device, is specifically related to orthopaedics percutaneous cervical arc root screw implantation accurate positioning device, belongs to technical field of medical instruments.
Background technology
Pedicle screw is the internal fixtion instrument of the treatment Thoracolumbar spine fracture that modern spinal surgery is commonly used, facts have proved in a large number at present its be a kind of safety, effectively, reliably Therapeutic Method, particularly the percutaneous cervical arc root screw of rising in recent years seems Wicresoft, intellectuality more on its basis, it is that screw is squeezed into vertebral body along the nail point that enters of having good positioning in advance that percutaneous cervical arc root screw inserts main method, thus fixing, decompressing effect is played to pathological changes vertebral body, thus recover its normal anatomy form.Its method relative to the advantage of conventional therapy be wound little, reduce the hospital stays, reduce amount of bleeding and reduce muscle injury, but, can percutaneous radix arcus vertebraetube enter the to perform the operation key of success or failure accurately screw is screwed into corresponding vertebral body, therefore, the inlet point of dog screw seems especially important; In prior art, need before percutaneous cervical arc root screw implantation to position pathological changes vertebral body; Conventional mapping methods is traverse Kirschner wire on the vertebral body of patient back, then repeatedly locate under C type wall, repeatedly Kirschner wire is moved up and down according to location, until finally orient pathological changes vertebral body pedicle locations, need repeated multiple times perspective, lack quantitative target, so not only extend operating time, and add the harm of x-ray to human body, equally also add financial burden to patient.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes orthopaedics percutaneous cervical arc root screw implantation accurate positioning device, registration, improving procedure efficiency and success rate.
(2) technical scheme
Orthopaedics percutaneous cervical arc root screw implantation accurate positioning device of the present utility model, comprises opacity, can autoclave sterilization, and has the check board of bio-compatibility; Described check board is made up of the grid bar of ten row equal-specifications; Described grid bar of often going is made up of the grid of seven equal-specifications; Independent differentiation character is made into integration in described grid; Described check board length is 10mm, and width is 8mm, and thickness is 2mm.
As preferred embodiment, described differentiation character comprises capitalization, lower case and Arabic numerals.
Further, described differentiation character and check board are made up of identical material.
(3) beneficial effect
Compared with prior art, orthopaedics percutaneous cervical arc root screw implantation accurate positioning device of the present utility model, in the process of operation, not only can effectively reduce fluoroscopy during operation number of times, to reduce medical personnel and patient's ray Exposure, and greatly can shorten operation and anesthesia duration, reduce the life security hidden danger of patient, this device is simple to operate simultaneously, in clinical easy popularization.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Orthopaedics percutaneous cervical arc root screw implantation accurate positioning device as shown in Figure 1, comprises opacity, can autoclave sterilization, and has the check board 1 of bio-compatibility; Described check board is made up of the grid bar 2 of ten row equal-specifications; Described grid bar of often going is made up of the grid 3 of seven equal-specifications; Independent differentiation character 4 is made into integration in described grid; Described check board 1 length is 10mm, and width is 8mm, and thickness is 2mm.
Described differentiation character 4 comprises capitalization, lower case and Arabic numerals.
Described differentiation character 4 is made up of identical material with check board 1.
During use, orthopaedics percutaneous cervical arc root screw implantation accurate positioning device of the present utility model is placed in patient vertebral body place, application C type wall is had an X-rayed, show that image is device and pedicle of vertebral arch and figure mark shadow superimposed images, distinguished by letter or number and accurately can locate pathological changes vertebral body pedicle of vertebral arch place aperture, and again can reach precise positioning pathological changes vertebral body pedicle of vertebral arch in micromatic setting position one by location graduation little on aperture, thus obtain inserting needle accurate location.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from this utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of this utility model request protection, all records in detail in the claims.
