Abstract

The invention relates to a vertebral plate opener for solving the problems that in the case of pushing a open-door side to open a vertebral plate in cervical posterior surgery, rongeurs are inconvenient to use, difficult to operate and poor in effect, and the vertebral plate is prone to rebound when being opened, resulting in dangerous accidents. A hook body is provided with a free end and a connection end, wherein the length of the free end of the hook body is smaller than that of the connection end, the top of the hook body is of a plane shape, the connection end of the hook body and a handle are connected to form a V shape, the opening of the V shape and that of the hook body are opposite in direction, and the handle and the free end of the hook body are arranged on two sides of the connection end of the hook body respectively. The vertebral plate opener is simple in structure, convenient to use, easy to operate, and capable of greatly increasing working efficiency. Further, the vertebral plate opener effectively solves the problem that the vertebral plate is prone to rebound when being opened, prevents medical incidents, and improves safety of operations.

Description

Vertebral plate raises device

Technical field

The present invention relates to medical apparatus and instruments, particularly a kind of vertebral plate raises device.

Background technology

Anterior cervical operation is owing to updating and promoting, and under treatment, cervical region and the change of short segment cervical spondylotic myelopathy achieve good result clinically, but solve Multilevel cervical spondylotic myelopathy and become still abnormal difficult. Therefore neck posterior approach then becomes the conventional modus operandi for the treatment of Multilevel cervical spondylotic myelopathy. Posterior approach is by expanding canalis spinalis, relies on the existence of physiologic radian, and spinal cord moves after " bowstring principle " effect is lower, alleviates front and causes and presses the thing compressing to spinal cord.

The operating procedure of present stage neck posterior approach is: patient takes prostrate, Qu Jing, upper body and raises position. Local infiltration anesthesia or general anesthesia, hit exactly straight cut after adopting neck, and after cutting ligamentum nuchae, subperiosteum is peeled off and appeared spinous process, bilateral lamina and articular process medial part, according to spinous process form location, appears lesion segment each vertebra up and down and saves. Punch in vertebral plate spinous process linking part, articular process medial border at both sides vertebral plate, side elects hinge side as, grind off or bite away vertebral plate outer cortex bone and part spongy bone, making V-arrangement bone groove, reach vertebral plate internal layer cortex but do not cut off bottom it, opposite side is enabling side, row strip Laminectomy, bilateral all should operate on vertebral plate inside articular process. Ligamenta flava between enabling sections upper and lower vertebral plate and under enabling sections vertebral plate is cut off, appears canalis spinalis. The each vertebral plate of sections " 10 " number silk thread that will open the door is suspended on the joint capsule of right side. Being opened by lateral hinge thruster of opening the door makes V-shaped part gradually draw close, and raises not easily wide, otherwise easily increases the probability of offside complete fracture, even cause to serious consequences such as intraspinal tube displacements. Appear dura mater, dural surface gelatin foam or take correspondingly sized fat sheet and cover. Wound puts negative-pressure drainage tube.

Neck posterior approach carry out pushing open enabling side raise vertebral plate carry out reducing pressure this step time, there is presently no special instrument, the rongeur generally using point mouth carries out pushing enabling side open and raises vertebral plate, serious consequence may be caused in this course due to the fixing shakiness of rongeur, such as, push enabling side open when raising vertebral plate, due to the fixing shakiness of rongeur, vertebral plate is raised when raising in enabling side, as easy as rolling off a log resilience, and beat on intraspinal spinal cord, cause the major accident that patient paralyses, therefore, so far, not yet have easy to use, easily operation, can be used in neck posterior approach to carry out pushing the operation tool that enabling side is raised in vertebral plate open.

Summary of the invention

For above-mentioned situation, for overcoming prior art defect, the purpose of the present invention is just to provide a kind of vertebral plate and raises device, can effectively solve neck posterior approach to carry out pushing open enabling side and raise in vertebral plate operation, rongeur in-convenience in use, difficult operation, weak effect, vertebral plate when raising, easy resilience, cause the problem that peril occurs.

The technical scheme that this invention address that is, coupler body has free end and link, the free end length of coupler body is less than the length of link, the top of coupler body is plane, the link of coupler body and the V-shaped connection of handle, V-arrangement opening and coupler body opening are rightabout, and the free end of handle and coupler body is respectively placed in the both sides of the link of coupler body.

Present configuration is simple, easy to use, easily operate, substantially increase work efficiency, efficiently solve vertebral plate problem of resilience when raising, it is to avoid the generation of malpractice, improves the safety of operation.

Fig. 2 is the schematic enlarged-scale view of the present invention.

Fig. 3 is the use view of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.

Provided by Fig. 1-Fig. 3, the structure of the present invention is, coupler body has free end 1 and link 2, the free end length of coupler body is less than the length of link, the top 3 of coupler body is plane, link and the V-shaped connection of handle 4, V-arrangement opening and the coupler body opening of coupler body are rightabout, and the free end of handle and coupler body is respectively placed in the both sides of the link of coupler body.

Described coupler body is the hook formation of the steel plate bending one-tenth of thick 2-4mm, wide 0.8-2cm.

Described coupler body inwall is evenly equipped with spiny tooth 5, it is prevented that slip.

The link 2 of described coupler body and handle link together through arc-shaped transition section 7.

The extrados of described arc-shaped transition section 7 has cone point 6.

Described arc-shaped transition section 7 is the plate body that bending is curved.

Free end 1 length of described coupler body is 2-6mm.

Link 2 length of described coupler body is 12-20mm.

Top 3 length of described coupler body is 3-6mm.

The length of described handle 4 is 10-15cm.

The link 2 of described coupler body and the angle of handle are 30-90 ��.

On described handle 4 fluted 8, conveniently hold, it is prevented that slip.

During use, the present invention is inserted from the enabling side of vertebral plate 10, the free end of coupler body is close on the vertebral plate medial wall of canalis spinalis 11, cone point is pressed against on the vertebral plate lateral wall in vertebral plate and the shifting type portion 9 of spinous process, fixed handle is pulled in direction, shifting type portion to vertebral plate Yu spinous process, can easily realize raising of enabling side vertebral plate, save time, laborsaving, enabling side vertebral plate is made to push open to hinge side vertebral plate, V-shaped part is made gradually to draw close, the width raised can according to dynamics free hold, rapidly, fast, enabling side vertebral plate is when raising, controlled by coupler body, without resilience, without slipping, devoid of risk, safe and reliable, easy to use, substantially increase work efficiency, efficiently solve potential safety hazard, avoid the generation of malpractice, thus reaching to accelerate decompression rate, improve the purpose of operation safety, in sum, the present invention has huge economic and social benefit.
