Abstract
The invention provides an artificial titanium alloy stabilizing-wing vertebral plate for the three-dimensional reconstruction shaping of vertebrae. The invention aims at providing an artificial titanium alloy stabilizing-wing vertebral plate, which is used for the three-dimensional reconstruction shaping of the vertebrae, can be used to replace a deleted spinous process and is artificially made by utilizing a titanium alloy as a main raw material. The titanium alloy is used as the raw material, and DICOM (Digital Imaging and Communications in Medicine) data is used as a standard for shaping. The vertebral plate is structurally characterized in that stabilizing wings are arranged at two sides of the lower end of the spinous process, guard plates are fixedly arranged at the connection parts between the spinous process and the stabilizing wings, side stabilizing wings are arranged at two sides of the guard plates, and holes are arranged on the spinous process, the stabilizing wings, the guard plates and the side stabilizing wings. According to the invention, the titanium alloy is used as the raw material, the DICOM data is used as the standard for shaping design, and a resin vertebrae die is successfully built by means of the DICOM data; and the die is subjected to trial installation and micro-adjustment to realize personalized treatment. The artificial titanium alloy stabilizing-wing vertebral plate provided by the invention has the advantages of high installation fitting degree, high anatomical simulation degree and the like.
Description
Technical field
The invention belongs to medical instruments field.
Background technology
The corrective surgery of vertebra and intraspinal tumor can be followed excision with vertebral plate or vertebral arch usually at present, causes the imperfect of vertebral body, erector spinae spinous process attachment point disappearance; Make vertebra be affected in load-bearing and turning to etc.; Poor stability, and the postoperative spinal cord do not have vertebral plate protection, and spinal cord is subject to adhesion, compressing; Muscle and spinal dura mater directly contact and can form epidural fibrosis behind the vertebrae plate resection, increase the weight of spinal compression.Because vertebrae plate resection, spinal cord loses the protection of vertebral plate, causes compression of spinal cord, adhesion, unstable spine, and various lumbago and skelalgia of clinical appearance and nervous symptoms, the inconvenience that brings huge misery and productive life for the patient is for society brings the tremendous economic loss.
Summary of the invention
The spinous process that the purpose of this invention is to provide a kind of alternative disappearance is the moulding titanium alloy stabilizer of the vertebra three-dimensional reconstruction artificial neural plate that primary raw material carries out manual manufacture with the titanium alloy.
The present invention is raw material with the titanium alloy; With the DICOM data is that template is moulding, and the vertebral plate structure is: in both sides, spinous process lower end are stabilizers, and spinous process and stabilizer junction are installed with backplate; The backplate both sides are the side stabilizer, and are porose on spinous process, stabilizer, backplate, side stabilizer.
The present invention is raw material with the titanium alloy, and it is moulding to be with the DICOM data that template designs, and successfully builds resin vertebra model through the DICOME data; Try to install and inching at model, realize personalized treatment, it is high to have the fitness of installation; Anatomy simulating degree advantages of higher; The complete titanium alloy structure of artificial neural plate that the present invention designs has advantages such as the good biochemistry compatibility and biomechanical compatibility, is sophisticated implantation property equipment material.The slippage that the stabilizer structure can effectively avoid correlation technique in the past to be difficult to avoid sink and wait the generation of displacement situation, and it is bigger to have stress area, and stress point is even, and RF is convenient to combine with the bone bed, is convenient to advantages such as sclerotin adheres to.Netted spinous process is convenient to muscle and is adhered to the anchoring fiber connective tissue and advantage such as seek connections with.The present invention also has simple for structure easy for installation, and wherein key technology such as three-dimensional reconstruction, titanium plate plastotype are all ripe, are convenient to produce, and preparatory installation of being taked and inching operating process realize personalized treatment, wait multiple novelty and characteristics, are convenient to clinical expansion.

The specific embodiment
The present invention is raw material with the titanium alloy, is that template is moulding with the DICOM data, builds resin vertebra model through the DICOME data, tries to install and inching at model.The vertebral plate structure is: in both sides, spinous process 2 lower end are stabilizers 1, and spinous process 2 is installed with backplate 3 with stabilizer 1 junction, and backplate 3 both sides are side stabilizer 4, and are porose on spinous process 2, stabilizer 1, backplate 2, side stabilizer 4.
The DICOME data collection and analysis carries out three-dimensional reconstruction: vertebra is carried out whole CT scan gather its DICOME data, carry out three-dimensional reconstruction, measure the vertebral plate related data and carry out statistical analysis.
Modelling of resin vertebral body and titanium alloy three-dimensional reconstruction fixed-wing artificial neural plate universal models are set up and are made: according to DICOME three-dimensional reconstruction data perfusion resin vertebral body model; And obtain each sections vertebral plate data of neck breast waist sacrum according to DICOME three-dimensional reconstruction DATA REASONING; Through statistics each sections vertebral plate data is analyzed; Obtain meansigma methods, carry out the three-dimensional data simulation, set up each sections artificial neural plate universal models.
Simulation is installed and inching: target vertebral plate model is simulated vertebra pull excision, choose the three-dimensional reconstruction titanium alloy stabilizer artificial neural plate of corresponding specification and simulate installation, and in installation process, carry out inching to owing anastomosis application titanium plate instrument.Artificial neural plate after the inching promptly can be installed and used.
On spinous process of the present invention 2, stabilizer 1, backplate 2, the side stabilizer 4 many holes are arranged, these holes first can alleviate the weight of the artificial vertebral plate of the present invention.The generation of displacement situation such as stabilizer 1 effectively avoids slippage with the hole on the side stabilizer 4, sink, and it is bigger to have stress area, stress point is even, and RF is convenient to combine with the bone bed, is convenient to sclerotin and adheres to.Supraspinous hole is convenient to muscle and is adhered to the anchoring fiber connective tissue and seek connections with.
