Abstract
The invention relates to a minimally invasive internal fixation fusion system for the anterior spinal column. The fusion system is a symmetrical structure and comprises two main nails, two assistant nails, two main and assistant nail connectors and a main nail connecting rod. The assistant nails are arranged in the main and assistant nail connectors in a penetrating manner. The main and assistant nail connectors are sleeved on the upper part of the main nail. The main nail connecting rod is locked in a groove arranged at the top of the main nail to connect the main nails on both sides. Compared with the prior art, a connecting rod is cancelled in the minimally invasive internal fixation fusion system for the anterior spinal column so that the operation is simpler, and internal fixation operation can be carried out by percutaneous puncture, therefore, the purpose of minimal invasion can be realized. The minimally invasive internal fixation fusion system for the anterior spinal column is used in a minimally invasive operation and has the advantages of alleviating pain of patients and reducing the operative difficulty, and being strong in adaptability.
Description
Technical field
The present invention relates to a kind of surgical operating instrument, especially relate to a kind of spinal column anterior minimally invasive internal fixation emerging system.
Background technology
Along with the development of surgery operating technology, Minimally Invasive Surgery is more and more accepted by surgeon and patient, in each ambit, all becomes one of development in future direction, also is like this at spinal surgery.At lumbar vertebra,,, carry out the patient of internal fixation fusion for needs owing to receive the restriction of operating theater instruments although the exploration of under endoscope, carrying out anterior approach is arranged; Still need carry out open surgery at present, big as far as patient's wound like this, hemorrhage many, as far as the doctor; Dissect complicacy, specification requirement is high, and difficulty is big; And complication is many, therefore can carry out doctor's limited amount of this type operation, is unfavorable for clinical popularization.Applied clinically at present lumbar vertebra internal fixation emerging system all needs open surgery to implant, and Minimally Invasive Surgery apparatus is not truly arranged at present as yet.
Summary of the invention
The object of the invention be exactly provide a kind of in order to overcome the defective that above-mentioned prior art exists and can in Minimally Invasive Surgery, use, simple to operate, spinal column anterior minimally invasive internal fixation emerging system that the suitability is strong.
The object of the invention can be realized through following technical scheme:
A kind of spinal column anterior minimally invasive internal fixation emerging system; It is characterized in that this emerging system is a symmetrical structure, comprise two main nails, two secondary nails, two major-minor nail adapters and a main nail pitman; Described secondary nail is located in the major-minor nail adapter; This major-minor nail adapter is set in the top of main nail, and described main nail pitman is fastened in the groove that main screw top portion offers, and connects the main nail of both sides.
Described main nail is hollow export-oriented staple, the sheathed U-shaped sleeve in top of this main nail.
The telescopic middle part of described U-shaped is a standing shape structure laterally, and the outside on top is provided with external screw thread, and the inboard is provided with female thread.
Described main nail pitman is fastened in the telescopic groove of U-shaped, and the top of this master's nail pitman is provided with the nut of fixing main nail pitman.
Described nut is provided with external screw thread, and the female thread coupling inboard with the U-shaped sleeve is connected.
On the U-shaped sleeve middle part standing shape structure laterally that described major-minor nail connector shelf is located at, the top of this major-minor nail adapter is provided with the fixedly pad of major-minor nail adapter, and this pad is set in the telescopic outside of U-shaped.
The inboard of described pad is provided with female thread, is connected with the external screw thread coupling in the U-shaped sleeve outside.
Offer screw on the described major-minor nail adapter, be equipped with secondary nail in the screw.
Described screw and vertical direction are provided with 20-25 ° angle.
Compared with prior art, the present invention has reduced by a pitman, makes that operation is simpler; And the internal fixation operation can be carried out under percutaneous puncture; Thereby can reach the purpose of Wicresoft, in Minimally Invasive Surgery, use, alleviate patient's misery; And reduced the difficulty of operation, the suitability is strong.
