A kind of new spinal endoscopic working channel systemTechnical field
The present invention relates to medical instruments field, particularly a kind of new spinal endoscopic working channel system.
Background technology
From the eighties in 20th century, minimally invasive spine surgery (MISS, minimal invasive spine surgery) technology obtained develop rapidly, and be in the field of businessly widely used and approve, for the whole world millions of meter spinal disease patient brings glad tidings, this technology is by the trend of the Fashion of Future field of spinal surgery development.MISS technical requirement spinal surgeons is by as far as possible little operative incision, use special operating theater instruments and device, under image documentation equipment auxiliary, complete whole operation process, dwindle otch to reach, reduce tissue injury and hemorrhage, improve manipulation accuracy and curative effect, promote the object of post-operative recovery.Compared with traditional open operation, MISS technology can reduce amount of bleeding, shortens operating time, reduces infection rate, saves medical expenses, alleviates patient suffering, promote post-operative recovery, shorten the hospital stays, and the motor function etc. of preservation spinal as much as possible.
Vertebral column minimally invasive service aisle has been the indispensable instrument of MISS technology, and it can be MISS technology effective working place is provided, and guarantees that operation completes smoothly in relatively narrow space, thereby reduces as far as possible the damage to surrounding tissue.Tubulose retractor is acknowledged as the service aisle of the suitableeest wound ISS technical need.It obtains operative approach by the muscle of riving, and can significantly reduce destruction to muscular tissue and the tractive of surrounding soft tissue, can shorten the hospital stays, reduces the generation of postoperative pain.Through the development of many decades, clinical practice is succeeded in developing and dropped into existing multiple tubulose vertebral column minimally invasive service aisle at present.But because existing vertebral column minimally invasive service aisle system exists:
The first, poor compatibility, need be used with specific Micro-operation system support;
The second, China is without independent intellectual property right, expensive, and the problem of corner on the market has greatly limited the promotion and application of MISS technology in China.
Summary of the invention
The problem existing for solving above-mentioned prior art, object of the present invention is for providing a kind of new spinal endoscopic working channel system.This system can compatibility most of Micro-operation systems in the market, and cost is low, and price is honest and clean.Can break abroad the breaking of this field, make the name family brand with China's independent intellectual property right, for MISS technology China extensively carry out and application creates favorable conditions.
For achieving the above object, technical scheme of the present invention is:
A kind of new spinal endoscopic working channel system, comprise service aisle pipe, connecting ring and for three assemblies of fixture of fixed endoscope, service aisle pipe is cylindrical, lower end one side becomes diagonal opening, upper end becomes horn-like oblique expanding, connecting ring inner surface is fitted and is threaded with the service aisle pipe portion of expanding, connecting ring upper surface is fixed with vertical joint pin, fixture for fixed endoscope is positioned at joint pin, endoscope and fixture can slide up and down along joint pin, described fixture comprises pedestal, on pedestal, perforate is used for running through joint pin, pedestal front end one side is stretched out and is provided with retainer ring, for fixed endoscope, pressing plate and susceptor pin connect, between pressing plate and pedestal, be provided with return spring, the large hole such as have at pedestal perforate correspondence position, on pedestal perforate and pedestal, the side of retainer ring is provided with and tightens screw.
Further, on described service aisle, be threaded connection connecting rod, connecting rod carries out spacing to connecting ring in the service aisle end degree of depth.
Further, described connecting ring side has through the center of circle, vertical operation channel axis to perforate, in perforate, be provided with steady pin.
Further, described service aisle has 8mm, 14mm, tri-kinds of models of 25mm according to internal diameter.
With respect to prior art, beneficial effect of the present invention is: delicate structure of the present invention, and reasonable in design, compatible good, can compatibility most of Micro-operation systems in the market; Cost is low, and price is honest and clean, has price advantage; Can break abroad the breaking of this field, make the name family brand with China's independent intellectual property right, for MISS technology China extensively carry out and application creates favorable conditions.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, technical solution of the present invention is described in further detail:
As shown in Figure 1, a kind of new spinal endoscopic working channel system, comprises service aisle pipe 1, connecting ring 2 and 3 three assemblies of fixture for fixed endoscope.Service aisle pipe 1 is cylindrical, remote design has a diagonal opening, as shown in Figure 3, service aisle pipe 1 one end becomes horn-like oblique expanding, on service aisle pipe 1, be threaded connection connecting rod 4, connecting rod 4 carries out spacing in the service aisle pipe 1 end degree of depth to connecting ring 2, and connecting rod 4 remote design become " spanner " shape structure, and be connected with other external fixing devices by this structure, whole service aisle system robust is fixed on operating-table.
Connecting ring 2 inner surfacies are fitted and are threaded with service aisle pipe 1 portion of expanding, and side has through the center of circle, vertical operation channel axis to perforate, in perforate, be provided with steady pin 5; Connecting ring 2 upper surfaces are fixed with vertical joint pin 6, are positioned at joint pin 6 for the fixture 3 of fixed endoscope, and endoscope and fixture 3 can slide up and down along joint pin 6.
As shown in Figure 2, described fixture 3 comprises pedestal 31, on pedestal 31, perforate is used for running through joint pin 6, pedestal 31 front end one sides are stretched out and are provided with retainer ring 32, for fixed endoscope, pressing plate 33 connects with pedestal 31 pins, between pressing plate 33 and pedestal 31, is provided with return spring 34, pressing plate 33 the large hole such as has at pedestal 31 perforate correspondence positions, and on pedestal 31 perforates and pedestal 31, the side of retainer ring 32 is provided with and tightens screw 35.
Further, described service aisle has 8mm, 14mm, tri-kinds of models of 25mm according to internal diameter.
Operation principle of the present invention is:
In actual use, select the service aisle pipe 1 of corresponding model according to patient's build, service aisle pipe 1 is connected with connecting ring 2, and fixing with steady pin 5, endoscope is connected in the retainer ring 32 of fixture 3, fixture 3 is socketed on joint pin 6 by pedestal 31 and the perforate of pressing plate 33, and tighten correspondence position tighten screw 35, need to regulate endoscope's height time, unscrew screw, depress pressing plate 33, after adjusting fixture 3 height, put down pressing plate 33, then tighten screw.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
