Abstract
The utility model discloses a digital spinal screw hole guide, which is applied to treatment of spinal fracture, spinal displacement and spondylolisthesis, and surgeries of spinal deformity. The digital spinal screw hole guide comprises a guide body provided with an inner surface fitted with a human vertebra, and a guide hole for guidance in drilling of spinal screw holes on the human vertebra. When a surgery is performed, the guide body is attached with the vertebra, a drill bit is disposed in the guide hole, and the vertebra can be drilled corresponding spinal screw holes by the aid of external force. The guide body and the guide hole are both designed through computer software and finished and formed through a numerical control machine, the guide body and the guide hole structurally completely meet mechanical requirements of spinal fixation, and the problem that bone screws cannot be accurately implanted into the human vertebra in the prior art can be solved.
Description
Technical field
This utility model relates to orthopaedics clinical treatment medical apparatus and instruments, relates in particular to a kind of digitized spinal screw hole guider that can accurately implant bone screw when spinal fracture, dislocation, centrum olisthe and deformity of spine are performed the operation for the treatment of.
Background technology
What clinical treatment spinal fracture, dislocation, centrum olisthe and deformity of spine were adopted at present is the mechanical fixation technology, its reinforce the connection at spinal column fracture or slippage position rod and be fixed on the vertebral body two ends with bone screw, by pitman and bone screw the spinal bone broken ends of fractured bone is stablized, its purpose replaces discontinued fracture power structure with fixed structure exactly, impel the spinal fracture healing or correct spondylolishesis or deformity, because this operation is very high to specification requirement, be difficult to grasp the accurate implantation position of bone screw.
The utility model content
Technical problem to be solved in the utility model is: a kind of digitized spinal screw hole guider is provided, this guide structure is simple, cost is lower, can be applicable to clinical treatment spinal fracture, dislocation, centrum olisthe and deformity of spine, can be implemented in human spine's corresponding site and accurately punch, thereby lay a solid foundation for implanting bone screw later on.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of digitized spinal screw hole guider, comprise the guider body, described guider body have one with the suitable inner surface of human body vertebral body, described guider body is provided with the pilot hole that guide effect is provided when boring system spinal screw hole to described vertebral body.
After having adopted technique scheme, the beneficial effects of the utility model are: since this digitized spinal screw hole guider have one with the suitable inner surface of human body vertebral body, its profile meets human spine's physiological curve fully, can guarantee in operation process that then vertebral body and guider body fit tightly, guarantee the degree of accuracy of operation.
Because be processed with the pilot hole that guide effect is provided on this digitized spinal screw hole guider, the angle of described pilot hole and position meet the needed mechanics requirement of spinal fixation, can implant bone screw exactly, thereby have guaranteed patient's smooth rehabilitation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of this utility model embodiment;
Wherein, 1. vertebral body; 2. guider body; 3. pilot hole.
The specific embodiment
As shown in Figure 1, view when using for this digitized spinal screw hole guider, need on vertebral body 1, implant bone screw by corresponding site in the operation process, this digitized spinal screw hole guider comprises guider body 2, described guider body 2 have one with the suitable inner surface of human body vertebral body 1, described guider body 2 is provided with at the pilot hole 3 that guide effect is provided when described vertebral body 1 is bored system spinal screw hole.
During operation, at first, patient's CT data generate three-dimensional data model by computer software, simultaneously calculate the needed mechanics requirement of spinal fixation by computer software, process guider body 2 by Digit Control Machine Tool, and the while processes pilot hole 3 on guider body 2, described guider body 2 have one with the suitable inner surface of human body vertebral body, its profile need meet human spine's physiological curve fully, the effect of described pilot hole 3 is that guide effect is being provided when described vertebral body 1 is bored system spinal screw hole, its angle and position meet the needed mechanics requirement of spinal fixation, certainly, described guider body 2 is preferably resistant to elevated temperatures plastics or metal is made; Then, in the operation process described guider body 2 is conformed on the human body vertebral body, in described pilot hole 3, place a drill bit, can on the human spine, get out corresponding spinal screw hole under external force; At last, described guider body 2 and drill bit are taken down, installed the synthetism device.
This utility model is not limited to the above-mentioned specific embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
