Abstract
The utility model discloses an assembled type thoracolumbar spine transverse process draw hook which comprises a transverse process hook and a fixed tail wing. The assembled type thoracolumbar spine transverse process draw hook is mainly used for drawing paravertebral muscles in thoracolumbar spine operations, spinous process, vertebral plates, zygapophysis and transverse process can be fully exposed, meanwhile, transverse process hook components with draw hooks of different heights can be selected according to the thickness of the paravertebral muscles of a patient, and therefore the purposes that fixing is reliable, exposure is adequate, selection is made according to individuals, and assembling is convenient are achieved. The assembled type thoracolumbar spine transverse process draw hook can be widely used for exposure of thoracic vertebra and lumbar vertebra bone diseases, traumas, deformity, inflammations and tumor posterior approach operations.
Description
Technical field
This utility model relates to a kind of being applied to when thoracic and lumbar vertebral posterior operation appears assists to retract paraspinal muscle, is conducive to fully appear the instrument of spinous process, vertebral plate, articular process and transverse process, especially adopts the breast transverse process of lumbar vertebra drag hook of assembly type structure.
Background technology
Spinal disease is the mankind's frequently-occurring disease, particularly along with the variation of environment, the development of expansion, traffic and the building trade of the prolongation of human longevity, people's activity space, the diseases such as spinal column osteopathia, wound, deformity, tumor and inflammation are increasing, become the main medical crowd of orthopaedics and the operation crowd that is in hospital, the crowd who is perplexing various ages of spinal disease, seriously affect patient's daily life and work, reduce people's quality of life, greatly destroyed social labor power.Along with the development of spinal surgery theory, the maturation of operating technology, operating theater instruments perfect, and the raising of patient to quality of life requirement, adopt posterior approach treatment to become a kind of selection widely, particularly thoracic and lumbar vertebral posterior Nuclectomy, spinal canal decompression, the various internal fixation methods of employing, or carry out the extensive use of bone graft fusion, thereby greatly improved the surgical result of breast lumbar disc disease simultaneously.Yet, appearing of art mesothorax lumbar vertebra posterior column structure be insufficient, the application of excessively the peeling off of fixing unreliable, soft tissue, unsuitable dilator, and long-time, the large-scale tractive of paraspinal muscle, not only affected operation technique, increase medical-risk and operating time, also may cause the extensive and serious infringement of paraspinal muscle, thereby cause breast failed back surgery syndrome, seriously affect the therapeutic effect of breast lumbar surgery and patient's quality of life.At present, the comparatively conventional apparatus that appears of thoracic and lumbar vertebral posterior operation mainly contains the automatic laminectomy retractor of bilateral, laminectomy retractor, rear cranium nest drag hook.Above-mentioned drag hook or too heavy, operation inconvenience; Need to carry out bilateral soft tissue and peel off, soft tissue damage is larger; Be not suitable for different build patients, or fixing inconvenience, easily get loose.
Utility model content
The purpose of this utility model is to provide the instrument of assisting to retract paraspinal muscle when a kind of thoracic and lumbar vertebral posterior operation appears.
This utility model solves be current appear apparatus appear insufficient, fixing unreliable, soft tissue is excessively peeled off, the long-time tractive on a large scale of paraspinal muscle, thereby the problem that increases medical-risk and extend operating time.
This utility model solves the technical scheme that its technical problem adopts: this utility model comprises transverse process hook and fixing empennage, and described transverse process hook is bending, and an adjutage is extended in one end of bent over arms, and the other end of bent over arms is a recess; One end of described fixedly empennage is provided with draw-in groove, and the other end is hooked shape structure.
Adjutage on described transverse process hook is provided with a bayonet socket.
Described fixedly empennage is provided with fixture block, spring and button in draw-in groove.
The bending angle of described transverse process hook bent over arms is 110 °, and the indent of bent over arms is offset 15 ° laterally with respect to coupled bent over arms section.
The drag hook height of described transverse process hook has three types, is respectively 60mm, 70mm and 85mm, and width is all consistent.
The beneficial effects of the utility model are: it is fixed pivot that this utility model is selected breast transverse process of lumbar vertebra, fixing reliable, be difficult for getting loose, and be multicomponent structures, assembly is convenient, and the rear that is applicable to different build patients appears, have wound little, appear effective, fixing firm, convenient disassembly, greatly shortened operation process, reduced operation wound, the surgical result of favourable raising breast lumbar disc disease.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
Fig. 3 is floor map of the present utility model.
Fig. 4 is use operation chart of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, this utility model comprises transverse process hook 5 and fixing empennage 1.
Transverse process hook 5 is bending, and an adjutage 4 is extended in one end of bent over arms 7, and adjutage 4 is provided with a bayonet socket 8, and the other end of bent over arms is a recess 6, and the shape of recess 6 and breast transverse process of lumbar vertebra matches.
Fixedly one end of empennage 1 is provided with draw-in groove 3, and the other end is hooked shape structure 9.
As shown in Figure 2, described fixedly empennage 1 is provided with fixture block 11, spring 10 and button 2 in draw-in groove 3, and spring 10 is enclosed within on fixture block 11, and the platform of button 2 and fixture block 11 contacts.
During installation, press the button 2, spring 10 presses down with fixture block 11, and the adjutage 4 of transverse process hook 5 inserts draw-in groove 3, until the position-limited edge on bent over arms 7 and draw-in groove 3 offsets, decontrols button 2, and spring 10 resets, and fixture block 11 just in time snaps in buckle 8 places of adjutage 4.Like this transverse process hook 5 and fixedly empennage 1 be just well fixed together.During dismounting, as long as press the button 2, fixture block 11 is separated with buckle 8 can extract transverse process hook 5 out.
As shown in Figure 3, the bending angle of described transverse process hook bent over arms 7 is 110 °, and recess 6 places of bent over arms 7 are offset 15 ° laterally with respect to coupled bent over arms section.
The drag hook height L1 of described transverse process hook 5 has three types, is respectively 60mm, 70mm and 85mm, and width is consistent.According to different patients' paraspinal muscle thickness choice for use, as partially thin in build, select the transverse process hook that drag hook height is lower, the partially fat person of build selects the lower high transverse process hook of drag hook height, and the medium person of build selects the medium transverse process hook of drag hook height.
As shown in Figure 4, along spinous process, vertebral plate, peel off a side erector spinae, according to patient's build, be the thickness of paraspinal muscle, select the transverse process hook 5 of proper height to be assemblied in fixedly empennage 1, transverse process hook 5 is buckled on transverse process, retract to greatest extent paraspinal muscle, then fixedly the common binder of empennage 1 use be fixed on operation table along or allow assistant be pinned, fully to appear, a gemmule is prominent, vertebral plate and articular process, is convenient to the operation of operation.
