Technical field
This utility model relates to a kind of surgical operating instrument, especially relates to a kind of Wicresoft's internal fixation fusing device that in the preceding road of spinal column, uses.
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 fusing device all needs open surgery to implant, and Minimally Invasive Surgery apparatus is not truly arranged at present as yet.
The utility model content
The purpose of this utility model 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, the Wicresoft's internal fixation fusing device that in the preceding road of spinal column, uses that the suitability is strong.
The purpose of this utility model can realize through following technical scheme:
A kind of Wicresoft's internal fixation fusing device that in the preceding road of spinal column, uses; It is characterized in that this fusing device 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.
Described major-minor nail connector shelf is located on the standing shape structure laterally of U-shaped sleeve middle part, and 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, this utility model 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.
Description of drawings
