Abstract
The utility model relates to a multiple jaw forceps holder type spine fixing device chiefly for the patients of the spine fracture operative treatment, the dislocation operative treatment, the spine backward convex operative treatment or the lateral bending shape-righting operative treatment. The multiple jaw forceps holder type spine fixing device has the bridge type structure and comprises two longitudinal plates. Transverse bridges are connected between the two longitudinal plates, and the outer side edges or double side edges of the both ends of the longitudinal plates are provided with jaw nails. The two longitudinal plates has the equal length, and the length of the transverse bridges can be equal or unequal. The middle sections of the cross bridges are slightly thin and are pre-bent to be circular arc-shaped for bringing convenience to the operation. Therefore, the multiple jaw forceps holder type spine fixing device has the advantages of easy operation, safe use, enough strength and enough stability.
Description
This utility model relates to a kind of human spine's inner fixer, and particularly a kind of multijaw clamp type spinal fixation device mainly is applicable to the patient that operative treatment spinal fracture, dislocation, kyphosis or lateral bending are orthopedic.
Internal fixation of spine device at present commonly used has: fixedly the spinous process steel plate of spinous process, fixedly the Harrinton system of vertebral plate and Luque system etc.These devices are all found some shortcomings in clinical use.Though the spinous process steel plate is safety fixedly, destructive little, fixedly owe firm; Harrinton, Luque system fix more reliable, but fixed-segment is many, and the danger that damages or increase the weight of Spinal Cord is arranged.
The purpose of this utility model is a kind of multijaw clamp type spinal fixation device of design, and the structure that adopts the pawl nail to engage with bridge type framework reaches easy and simple to handle, safe in utilization, has enough intensity and stable purpose.
Multijaw clamp type spinal fixation device is bridge architecture, includes two stringer boards, is connected by cross-bridges between two stringer boards, is provided with the pawl nail on the lateral border at stringer board two ends or bilateral edge.Two stringer boards are isometric, and cross-bridges length can equate or not wait, and the stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc, are convenient to operation.Position difference according to spinal fixation can be provided with the plurality of specifications model, and the quantity of the stringer board of every kind of model and the length of cross-bridges, pawl nail is set as required.
The multijaw clamp type spinal fixation device that this utility model is designed, be fixed on human body vertebral plate and spinous process intersection (or claiming the spinous process root) by a plurality of pawl nails during use, the thickness of this position sclerotin and hardness are all bigger than vertebral plate and spinous process, add dewclaw and follow closely many stress dispersions, so enough intensity and stability are arranged; The clamp application of force by uniqueness fixes, and avoid boring, twisted screw, worn complex process such as steel wire, thereby simple operation; Only need appear the spinous process and the vertebral plate of spinal posterior when adopting this holder operation, not invade the DEEP STRUCTURE of vertebra, thereby use also very safe.
Fig. 1 is multijaw clamp type spinal fixation device embodiment one structural representation.
Fig. 2 is multijaw clamp type spinal fixation device embodiment two structural representations.
Fig. 3 is multijaw clamp type spinal fixation device embodiment three structural representations.
Fig. 4 is multijaw clamp type spinal fixation device embodiment four structural representations.
Embodiment one: structure as shown in Figure 1 is used for fixing cervical vertebra.Include two stringer boards (1), between two stringer boards, connect, on the bilateral edge at stringer board two ends, be respectively equipped with pawl nail (3), (4) by two cross-bridges (2).The stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc.
Embodiment two: structure as shown in Figure 2 is used for fixing spinal column breast section or breast waist section.Include two stringer boards (5), between two stringer boards, connect, on the lateral border at stringer board two ends, be provided with pawl nail (7) by two cross-bridges (6).The stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc.
Embodiment three: structure as shown in Figure 3 is used to correct spinal column breast section or breast waist section lateral bending deformity.Include two stringer boards (8), between two stringer boards, connect, on the lateral border at stringer board two ends, be provided with pawl nail (10) by three cross-bridges (9).The stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc.
Embodiment four: structure as shown in Figure 4 is used for fixing lumbar spine or breast waist section.Include two stringer boards (11), between two stringer boards, connect, on the bilateral edge at stringer board two ends, be respectively equipped with pawl nail (13), (14) by two cross-bridges (12).The stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc.
The section of stringer board, cross-bridges, pawl nail can be tetragon, circle, semicircle or other shape.Every group of pawl nail has two to more than two.Multijaw clamp type spinal fixation device, material therefor can be medical stainless steel, titanium, titanium alloy and marmem.The pawl nail is pressed in the sclerotin of vertebral plate and spinous process intersection (or claiming the spinous process root) and spinous process by the clamp application of force during use, supporting with it special equipment is: clamp pincers and pre-curved forceps, the clamp pincers can be exerted pressure to the pawl nail and be made it to embed in the sclerotin, pre-curved forceps can carry out pre-bending to stringer board, makes it consistent with the spinal column radian of desiring fixed-segment.
Claims (2)
1, multijaw clamp type spinal fixation device is characterized in that being bridge architecture, includes two stringer boards, is connected by cross-bridges between two stringer boards, is provided with the pawl nail on the lateral border at stringer board two ends or bilateral edge.
2, multijaw clamp type spinal fixation device according to claim 1 is characterized in that two stringer boards are isometric, and cross-bridges length can equate or not wait that the stage casing of cross-bridges is slightly thin, and pre-bending is circular-arc.
