Description

A kind of universal positor of vertebral body that is used for the orthopaedics spinal operation

Technical field

This utility model relates to the universal positor of a kind of orthopaedics, is meant a kind of universal positor of vertebral body that is used for the orthopaedics spinal operation especially, belongs to technical field of medical.

Background technology

Along with the progress of medical skill, pathological changes vertebral body or the fixed operation of the laggard horizontal reset of the whole excision of lopsided vertebral body are at clinical implementation.Implementing in this type of operation process, between upper and lower two sections vertebral bodys of the pathological changes vertebral body of the whole excision of need or lopsided vertebral body, carry out reliably temporary fixed and operative reduction accurately, is the successful important step of performing the operation.

At present, clinical implementation this type of when operation, between upper and lower two sections vertebral bodys of the pathological changes vertebral body of the whole excision of need or lopsided vertebral body, carry out temporary fixedly with existing spinal column internal fixation device, complicacy is installed, and inner fixer can hinder the operation of operation; Operative reduction is to wait instrument, realize by manpower that fully physical strength is big with the existing rod pincers of holding, and stable inadequately, reliable and accurate.

Existing many for the online patent application that is installed in the intravital orthopaedics spinal column internal fixation device of people, some are also arranged is special equipment and mis instruments that the orthopaedics spinal column internal fixation device is installed, like following documents:

Documents 1; The patent No. is to disclose a kind of vertebra joint coupling in 200720302026 the Chinese patent document, and it comprises first Connection Block, second Connection Block; Connecting rod and Non-slip material, said Non-slip material are located between said first Connection Block and said second Connection Block; Said connecting rod is separately fixed on the upper and lower vertebrae; Said first Connection Block and said second Connection Block are the movable sleeve integrator.It is quick, simple and easy that its advantage is that this vertebra joint coupling has the characteristic and an operation technique of the angle limits of not receiving, and can simultaneously knot once be locked in the position that is separately fixed at the connecting rod on the upper and lower vertebrae with single locking action and be fixed on the adapter.

Documents 2, the patent No. are to disclose a kind of scalable cross-connecting apparatus and spinal internal fixation system in 200920208630 the Chinese patent document, and it comprises first, second connector, has the supporting part that is suitable for holding vertical spinal rods.Connecting device also comprises the cross bar that is used to connect first, second connector.Wherein, first, second connector has first, second end that holds cross bar and first, second jack that cooperates with both ends.And the first end of cross bar has bulb, and this bulb rotatably is assemblied in first jack.Through such structure, the number at the position that can effectively take in sail significantly improves the steadiness of fixed system, and the convenience of operation technique, has also reduced the risk that part is lost simultaneously.

Documents 3; The patent No. is to disclose a kind of bar clamper and utilized the vertebra of this bar clamper to use minimally invasive surgery system in 201010001151 the Chinese patent document; Thereby it relates to the bar clamper that bar can easily be installed with the operation of secondary load mode; Its order, regulate the gripping state of bar with three grades of modes: in the first loading stage, retreat and be fixed through making loading part, thereby control bar securely according to following three phases; In the second loading stage, rotatably control bar; With the bar erection stage, bar clamper and Bar Splitting System Based are left.This utility model also relates to a kind of vertebra and uses minimally invasive surgery system; Bar clamper capable of using, bar guider and bar guider hold assembly more accurately and stably are installed to bar in the pedicle screw that is inserted into vertebrae; It comprises: a pair of bar guider that is connected with the upper end of a pair of pedicle screw, and it forms the mobile route of bar; The bar clamper of clamping bar; And bar guider hold assembly, limit the insertion path of bar clamper, and regulate the on position of bar.

Can find out with documents 2 through above-mentioned documents 1; When vertebra joint coupling, adjusting cross-connecting apparatus etc. are orthopaedics internal fixation of spine operation; Be implanted in a fixed part of the intravital orthopedic fixation device of people, these parts work to connect fixedly implant; This series products has various ways to occur clinically, all is the difference on adjusting and the fixed structure.

Can find out through above-mentioned documents 3, when vertebra is orthopaedics internal fixation of spine operation with minimally invasive surgery system, the special equipment of orthopaedics spinal column internal fixation device is installed, can reach the purpose of orthopaedics internal fixation of spine operation Wicresoft.

But; When the orthopaedics internal fixation of spine is performed the operation, install in the process of orthopaedics spinal column internal fixation device; The disconnected intersegmental needs of two bones carry out temporary fixed and operative reduction behind fracture or the resected bone; Find as yet clinically at present can satisfy temporary fixed and the bone surgery instrument operative reduction requirement, operating time is long like this, operation risk is big, also can influence the quality of operation.

In view of this; Design a kind of simple to operate laborsaving, temporary fixed quick reliable, operative reduction is meticulous accurately, can satisfy the operating theater instruments of this type of operation clinical requirement, seems very necessary, so; The designer of this utility model is through experimental study constantly and improvement; Finally design a kind of universal positor of vertebral body that is used for the orthopaedics spinal operation, this positor is when the disconnected intersegmental installation orthopedic fixation device of two bones is performed the operation behind fracture or resected bone, to carry out temporary fixed and special-purpose bone surgery instrument operative reduction; In the bone surgery process, using, is not to be implanted in the human body.
