Description
Technical field
This utility model relates to a kind of exsector, relates in particular to a kind of spinal column digitized operation soft tissue exsector.
Background technology
The at present annual whole world has thousands of spinal fracture, tumor of spine, scoliosis, intervertebral disk hernia, spinal canal stenosis, spondylolishesis patient to carry out various spinal operations, as fixing in laminectomy for decompression, pedicle nail, vertebroplasty, Nuclectomy etc.Because the vital tissues such as spinal cord, blood vessel and internal organs are positioned at around canalis spinalis or vertebra, operate miss is inserted as pedicle nail and is penetrated pedicle of vertebral arch cortical bone, nucleus pulposus clamp gos deep into the catastrophic effects such as even death that may cause paralysing such as abdominal cavity.Therefore, accurately location, precisely operate in field of spinal surgery tool and be of great significance.A lot of for the method for spinal surgery location at present, insert as example with pedicle nail, roughly can be summarized as five kinds: 1 artificial vertebral surface bone mark location is aided with the method such as Electrophysiology and the electrical impedance monitoring placing directions such as the positive side of x-ray position perspective, somatosensory evoked potential and electromyogram, generally adopt clinically at present, precision is poor.It guides 2 computer assisted navigations based on global positioning system (GPS) principle, be stored in " virtual world coordinate system " by the data of obtaining after preoperative targeted vertebra CT, MRI 3-dimensional reconstruction, Intraoperative position device is based upon the locus of targeted vertebra and operating theater instruments " real-world coordinates system " in real time again, then inserts by the coupling guiding pedicle of these two coordinate systems.Due to be subject to image drift, tracing system disturbed, can not real-time dynamic monitoring etc. the impact of many factors, bibliographical information the method is used for breast lumbar vertebra, and complex operation is time-consuming.This method of 3 Digitalized guiding template and computer assisted navigation principle are similar, are preoperative need, by computer control according to the reserved pilot hole masterplate of vertebral surface shape processing, being buckled in vertebral surface guiding pedicle nail and inserting in art.Obviously, this method is subject to the impact of vertebral surface situation, need bone surface in a big way to appear, and surperficial convex-concave changes greatly, and the goodness of fit of template and bone surface is just higher, and guiding accuracy is also just higher.Do not appear or the Minimally Invasive Surgery such as the very little percutaneous that appears vertebral surface in, the method is difficult to application.4 operating robots are as the Spineassiant(spinal column assistant of Israel), the robotic surgical system of the operation guiding system based on C arm machine 2D image in art, the O arm guiding based on optically tracked operating robot-SPINEBOT, Germany of Korea S etc.Adopt computer assisted navigation principle or need guide by high-end image documentation equipment, not only in art ray to expose many costs also very expensive.(5) some other localization method in other prior aries, as framework location, owing to there being wound to be tending towards at present superseded.Based on the stereotactic surgery system of CT, MRI scanning in specific underframe, utilize scanning cover registration precision higher, but can only carry out at CT or MRI chamber, application is limited to; Adopt body surface mark registration, owing to can not guaranteeing in art and preoperative position is consistent and the movement of skin and positioning precision is lower, can only be used for the less demanding bone surgery of performance accuracy.
In view of this, urgently for above-mentioned technical problem, a kind of spinal column digitized surgery systems based on location, microgap of the design that looks for another way.Meanwhile, need to provide a kind of exsector that coordinates digitized operation to excise for soft tissue.
Utility model content
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, provides a kind of spinal column digitized to perform the operation and uses soft tissue exsector.
The purpose of this utility model is achieved through the following technical solutions:
Spinal column digitized operation soft tissue exsector, include cutter body, wherein: on described cutter body, be provided with driven unit, on the working end of described driven unit, be connected with cutter hub, described cutter hub termination is provided with blade, described cutter hub periphery is distributed with and holds down assembly, and is provided with attraction assembly in the periphery that holds down assembly, and the end of described attraction assembly is provided with base.
Further, soft tissue exsector is used in above-mentioned spinal column digitized operation, wherein: on described base, be provided with boss.
Further, soft tissue exsector is used in above-mentioned spinal column digitized operation, wherein: the described periphery that holds down assembly is provided with elastic parts.
Further, soft tissue exsector is used in above-mentioned spinal column digitized operation, wherein: described elastic parts is spring, and described spring is arranged on the periphery of the rear that holds down assembly.
Further, soft tissue exsector is used in above-mentioned spinal column digitized operation, wherein: described holds down assembly as compressing pipe.
Further, soft tissue exsector is used in above-mentioned spinal column digitized operation, wherein: described attraction assembly is suction catheter.
Again further, soft tissue exsector is used in above-mentioned spinal column digitized operation, and wherein: described driven unit includes motor, the work termination of described motor connects cutter hub by drive mechanism.
The advantage of technical solutions of the utility model is mainly reflected in: can meet common spinal column digitized operation needs, pathological tissue is effectively excised.Meanwhile, in whole cutting-off process, rely on base, boss coordinates with attraction assembly, can draw in time tissue, does not affect the enforcement of subsequent procedures.And, can meet the needs that automatic operation is implemented.Moreover this utility model simple structure, is easy to manufacture, and can be installed on various standardized digitized surgical apparatuses.
