Abstract
The utility model discloses a minimally invasive intraspinal fixation device, comprising a fixation rod and a plurality of screws, wherein each screw is connected with the fixation rod through a respective connecting sleeve; one end of each screw is provided with a multi-shaft positioning-connecting mechanism that is sheathed at one end of one connecting sleeve; the fixation rod passes through each connecting sleeve; and the other end of each connecting sleeve is provided with a thread and connected with a nut fixing unit. By the minimally invasive intraspinal fixation device, the effect and success rate of an operation can be improved, and operative complications and operation injury are reduced. The mechanism of the fixation device is based on the physiological curvature of waist and sacrum spine; the principle of mechanical transmission is utilized and operation requirements are combined in the fixation device. A clinically dedicated special orthopedic nail and an orthopedic rod are used for minimally invasive surgery to treat spinal fracture, amputation and other diseases. By adopting minimally invasive closed surgery, only little injury is caused to muscle when the nail and the rod are placed in, and the operation is enabled to have the characteristics of minimal invasion, little bleeding, short time, satisfied result and the like.

Background technology
Minimally-invasive internal fixation of spine device is applicable to spinal surgery internal fixation of spine hands art; It is unstable to be used to treat waist, sacrum portion single-unit section and two segment, to suffering from diseases such as intervertebral disk hernia, deformity of spine correction, fracture, tumor resection.
Comply with on " Wicresoft " technological essence and satisfied the patient, become one of developing direction and main development trend of whole technique of surgical treatment the higher demand of surgery therapeutic effect.
The vertebral column minimally invasive technology becomes the focus of global spinal surgery circle in recent years gradually, also is one of main flow trend of spinal surgery development, and along with the release of vertebral column minimally invasive series, the vertebral column minimally invasive technology is at American-European high speed development over nearly 4 years.
The utility model content
This utility model technical problem to be solved is: a kind of minimally-invasive internal fixation of spine device is provided, can improves surgical effect and success rate, reduce postoperative complication and surgical injury.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of minimally-invasive internal fixation of spine device, said device comprises: hold-down bars, some screws, each screw is connected with hold-down bars through adapter sleeve separately; One end of said screw is provided with the multiaxis mechanism that is located by connecting, and the multiaxis mechanism that is located by connecting is enclosed within an end of adapter sleeve, and hold-down bars passes each adapter sleeve; The other end of said adapter sleeve is provided with screw thread, is connected with the fixed by nut unit.
As a kind of preferred version of this utility model, an end of said hold-down bars is provided with the groove bayonet socket.
As a kind of preferred version of this utility model, said fixed by nut is provided with anti-skidding buttless thread outside the unit.
As a kind of preferred version of this utility model, said hold-down bars is the arc rod.
The beneficial effect of this utility model is: the minimally-invasive internal fixation of spine device that this utility model proposes, can improve surgical effect and success rate, and reduce postoperative complication and surgical injury.This utility model fixture mechanism is utilized mechanical drive principle according to the physiologic radian of waist, sacrum portion spinal column, and in conjunction with the operation technique requirement, clinical special use is special orthopedic with nail and orthopedic with rod employing Minimally Invasive Surgery, solves diseases such as spinal fracture, cut-out.Owing to adopt the enclosed operation of Wicresoft, less when inserting the nail rod to muscle injury, making operation have low wound, go out insufficiency of blood, the time is short, finish characteristics such as satisfied.
Description of drawings
Fig. 1 is the structural representation of this utility model minimally-invasive internal fixation of spine device.
The specific embodiment
Specify the preferred embodiment of this utility model below in conjunction with accompanying drawing.
Embodiment one
See also Fig. 1, this utility model has disclosed a kind of minimally-invasive internal fixation of spine device, and said device comprises: hold-down bars 1, some screws 2, each screw 2 is connected with hold-down bars 1 through adapter sleeve 4 separately.One end of said hold-down bars 1 is provided with the groove bayonet socket.
One end of said screw 2 is provided with the multiaxis mechanism 3 that is located by connecting, and the multiaxis mechanism 3 that is located by connecting is enclosed within an end of adapter sleeve 2, and hold-down bars 1 passes each adapter sleeve 4; The other end of said adapter sleeve 4 is provided with screw thread, is connected with fixed by nut unit 5, is provided with anti-skidding buttless thread outside the said fixed by nut unit 5.
In a kind of embodiment of this utility model, said hold-down bars 1 is the arc rod.
The mechanism of this utility model is: the physiologic radian according to waist, sacrum portion spinal column, utilize mechanical drive principle, and in conjunction with the operation technique requirement, clinical special use is special orthopedic with nail and orthopedic with rod employing Minimally Invasive Surgery, solves diseases such as spinal fracture, cut-out.Owing to adopt the enclosed operation of Wicresoft, less when inserting the nail rod to muscle injury, making operation have low wound, go out insufficiency of blood, the time is short, finish characteristics such as satisfied.
Can cooperate spinal operation in this utility model fixture, design and manufacture more advanced operating equipments, the step is simplified operation technique on original open surgery is basic enterprising; Shorten operating time, improve surgical effect and success rate, reduce postoperative complication and surgical injury; Alleviate less patient suffering; Reduce surgery cost, shortened operating time, enlarged the operation scope of application.
Utilize this utility model to carry out minimally invasive spine surgical and possess following advantage:
1, operative incision is little: general four nails, four rods only need bore 6 in φ 1.5cm hole;
2, need not pull hook: operative incision is cut, less to muscle injury;
3, little to the skeleton influence: as need spinous process not cut off, so the patient can just can leave hospital in common three days, and open surgery to need a week at least usually than easy rehabilitation;
4, go out insufficiency of blood: because damaged area is little, therefore blood transfusion is also few, at most only needs 200ml, and the open surgery 400ml-600ml that need transfuse blood usually;
5, sequela is little: be difficult for causing discomforts such as the soreness of waist, backache after the operation;
6, nail tail diameter is little: comprising under the effect same that orthopedicly can be kept to φ 12.5 from original φ 14 with nail, because volume-diminished, not only operation technique is convenient, and quickening patient rehabilitation;
7, operating theater instruments: the special-purpose operating equipment of the main employing of operation, its interchangeability, operating characteristics is improved greatly;
8, risk: the Minimally Invasive Surgery risk is lower, still can adopt open surgery to operate like nail, excellent misalignment in the operation, can risk be dropped to bottom line like this.
Here description of this utility model and application is illustrative, is not to want the scope of this utility model is limited in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation of spirit that does not break away from this utility model or substitutive characteristics, and this utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from this utility model scope and spirit, can carry out other distortion and change here to the embodiment that is disclosed.
