Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of spinal pedicle puts nail soft tissue protector.
Background technology
Pedicle of vertebral arch is part the strongest on vertebra, is the useful effect point that backbone is operated and braked.Vertebral arch
Root section is oval, is around cortex bone, and there is a little cancellous bone at center, and rear portion is almost cortex bone entirely, the firmest at this,
Transverse process, cone-plate, the lower articular of vertebra dash forward can in pedicle of vertebral arch same point, all power that centrum is transmitted to from backbone rear
Pass through this point.Pedicle instrument can maintain the normal anatomy of backbone, protect to the maximum extent while obtaining effectively fixed
Stay the motion segment of backbone.Centrum is inserted screws by pedicle of vertebral arch, the composite construction of backbone entire " three columns " can be controlled, reached
To preferable three-dimensional fixed function.It is treatment deformity of spine, fracture dislocation of spine merging and tumor of spine that pedicle of vertebral arch, which puts nail technology,
Effective therapeutic scheme.
But medical staff has found that the backbone of small notch puts tack operation in the completed in clinical position, backbone notch exists
The situation of delayed union, it is that the instruments such as pedicle screw cause one to the soft tissue near backbone in spinal operation to trace it to its cause
Determine the damage of degree, this pain for being not intended to aggravate patient and increase the cost of medical service of patient during one's sickness.
Invention content
Goal of the invention the defects of being to overcome described in background technology of the present invention, is cut so as to fulfill one kind backbone is small
Mouth, which is put, is avoided that medical instrument causes backbone surrounding soft tissue the spinal pedicle of damage to put nail soft tissue protection in tack operation
Device.
For achieving the above object, the technical scheme is that：A kind of spinal pedicle puts nail soft tissue protector,
Including half opening casing and holding mechanism, the half opening bushing head opening setting, barrel side is opened along casing length direction
Equipped with strip notch, the strip notch is communicated with half opening casing head end opening, and the half opening casing head end is open
Diameter follows closely tail diameter matches with pedicle screw, makes pedicle screw nail tail that be able to be inserted in half opening casing head end；Described half
The closing setting of split coupling tail end, the half opening cannula end diameter be able to be placed in nail device；The half opening casing tail
Holding mechanism is symmetrically fixedly installed in end both sides.
As the preferred technical solution of the present invention, semicircular is provided on the half opening casing upper edge casing length direction
Graduation mark, the graduation mark is set on the opposite half opening casing of strip notch.
As the preferred technical solution of the present invention, the holding mechanism, which is that half opening cannula end both sides are symmetrically arranged, to be held
Bar is held, caudad direction tilts setting to the holding rod, and holding rod can prevent its rotation for fixing half-open port sleeve, into one
Step increases the success rate of operation.
As the preferred technical solution of the present invention, the material of half opening casing and holding mechanism is stainless steel, medical
Stainless steel ensure that this protector will not cause superinfection, ensure that smoothly completing for operation.
The spinal pedicle of the present invention puts the advantageous effect of nail soft tissue protector：
1. the spinal pedicle of the present invention puts nail soft tissue protector, half opening casing head end wraps pedicle screw nail tail,
Half opening cannula end is installed with putting nail device cooperation, backbone surrounding soft tissue and sharp keen medical instrument is isolated, effectively
The backbone small notch that avoids put medical instrument in tack operation and damage caused to happen backbone surrounding soft tissue, therefore protect
The rehabilitation healing rate of backbone notch after surgery has been demonstrate,proved, has alleviated the pain of patient's operation.
2. the spinal pedicle of the present invention puts nail soft tissue protector, half opening cannula end both sides, which are symmetrical arranged, to be useful for
Fixed holding rod, caudad direction tilts setting to the holding rod, and holding rod can prevent it for fixing half-open port sleeve
Rotation further increases the success rate of operation.
3. the spinal pedicle of the present invention puts nail soft tissue protector, the material of half opening casing and holding mechanism is stainless
Steel material, medical stainless steel material ensure that this protector will not cause superinfection, ensure that smoothly completing for operation.
