Abstract
The utility model relates to a nerve tension measuring device for spinal surgery, including ergograph, nerve root traction lever and sleeve, the sleeve in install gliding nerve root traction lever from top to bottom, this nerve root traction lever upper end is passed the sleeve and is linked to each other with the ergograph, one side of sleeve lower extreme seted up horizontal opening, nerve root traction lever lower extreme be provided with and pass horizontal open-ended hook portion. The utility model discloses horizontal open-ended highly has restricted the scope of activity from top to bottom of hook portion to play the effect that the nerve root traction lever was excessively carried and is drawn the nerve, when the nerve root traction lever carried maximum height, the nerve root traction lever had a mark circle just in time to expose telescopic last port, makes things convenient for the observer to observe.
Description
Technical Field
The utility model relates to the technical field of medical treatment, especially, relate to a nerve tension measuring device for spinal surgery.
Background
The root cause of pain caused by the compression of nerves by lumbar disc herniation is the increase in nerve root tone. Usually, in spinal surgery, the change of nerve root tension before and after the surgery needs to be measured to judge whether the surgery meets the requirement of loosening nerve roots.
At present, tension of nerve roots is measured in spinal surgeries, the nerve roots are pulled up by a nerve root traction rod, and the nerve tension is directly measured by a measurer.
Disclosure of Invention
The utility model aims to solve the technical problem that a neural tension measuring device for spinal surgery is provided, horizontal open-ended highly restricted the scope of activity about the hook portion to play the effect that the nerve root traction lever was excessively carried and is drawn, when the nerve root traction lever carried maximum height, the nerve root traction lever had a mark circle just in time to expose telescopic last port, made things convenient for the observer to observe.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a nerve tension measuring device for spinal surgery, includes ergograph, nerve root traction lever and sleeve, the sleeve in install gliding nerve root traction lever from top to bottom, this nerve root traction lever upper end is passed the sleeve and is linked to each other with the ergograph, one side of sleeve lower extreme seted up horizontal opening, nerve root traction lever lower extreme be provided with the hook portion that passes horizontal opening, the nerve root traction lever on be provided with the mark circle, when hook portion runs into horizontal opening top, the mark circle just flushes with sleeve last port.
As a supplement to the technical proposal of the utility model, one side of the upper part of the sleeve is provided with a horizontal handle.
As right technical scheme a supplementary, the handle lateral wall arranged the non-slip texture.
As a supplement to the technical solution of the present invention, the free end of the hook portion is provided with a spherical protrusion.
As a supplement to the technical scheme of the utility model, nerve root traction lever upper end and ergograph between adopt the screw thread to connect soon.
Has the advantages that: the utility model relates to a nerve tension measuring device for spinal surgery has following several advantages:
1. the height of the horizontal opening limits the range of the vertical movement of the hook part, so that the function of limiting the nerve to be excessively pulled by the nerve root traction rod is achieved, when the nerve root traction rod is lifted to the maximum height, a marking ring of the nerve root traction rod is just exposed out of the upper port of the sleeve, and an observer can conveniently observe the nerve root traction rod;
2. the upper part of the sleeve is provided with a handle which provides a holding place for the sleeve, and the outer side wall of the handle is provided with anti-skid lines which can play a certain anti-skid role;
3. the free end of the hook part is provided with a spherical bulge, and the spherical bulge is designed to prevent the nerve from being pulled;
4. the upper end of the nerve root traction rod is screwed with the force measuring device through threads, other fixing modes can also be adopted, the force measuring devices on the market are provided with hooks, and the hooks are removed, and then the threads are added to be screwed with the nerve root traction rod.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The figure is as follows: 1. the device comprises a handle, 2, anti-skid lines, 3, a force measuring device, 4, a marking ring, 5, a nerve root traction rod, 6, a sleeve, 7, a hook part, 8, a horizontal opening, 9 and a spherical bulge.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model discloses an embodiment relates to a nerve tension measuring device for spinal surgery, as shown in fig. 1, including ergograph 3, nerve root traction lever 5 and sleeve 6, sleeve 6 in install gliding nerve root traction lever 5 from top to bottom, this nerve root traction lever 5 upper end is passed sleeve 6 and is linked to each other with ergograph 3, one side of 6 lower extremes of sleeve seted up horizontal opening 8, 5 lower extremes of nerve root traction lever be provided with the hook portion 7 that passes horizontal opening 8, nerve root traction lever 5 on be provided with mark circle 4, when 8 tops of horizontal opening are met to hook portion 7, mark circle 4 just flushes with 6 last ports of sleeve. The height of the horizontal opening 8 is 5mm, the height of the horizontal opening 8 limits the range of the vertical movement of the hook part 7, so that the effect of limiting the nerve to be excessively pulled by the nerve root traction rod 5 is achieved, when the nerve root traction rod 5 is 5mm in maximum height, the nerve root traction rod 5 is provided with a marking ring 4 which just exposes out of the upper port of the sleeve 6, and observation of an observer is facilitated.
One side on sleeve 6 upper portion be provided with horizontally handle 1, this handle 1 provides the place of gripping for sleeve 6, 1 lateral wall of handle arranged anti-skidding line 2, this anti-skidding line 2 can play certain anti-skidding effect.
The free end of the hook part 7 is provided with a spherical bulge 9, and the spherical bulge 9 is designed to prevent the nerve from being pulled.
The upper end of the nerve root traction rod 5 is screwed with the force measuring device 3 by screw threads, and other fixing modes can be adopted. The ergograph 3 is formed by removing the hook and then screwing the hook with the nerve root traction rod 5.
