The working pipe system of the spinal paramedian keyhole approach is convenient to operate, good in stability and good in view after location at the operation area. The working pipe system comprises a fixing device, an operation channel pipe with a fixed clamping groove, a puncturing locating needle and a set of dilation tubes with gradually increased diameters, wherein the operation channel pipe is fixed on the fixing device through the fixed clamping groove, and the specification of each dilation tube is that the inner side wall diameter of dilation tube of the upper level is equal to the outer side wall diameter of dilation tube of the next level, and the outer diameter of the dilation tube at the highest level is equal to the inner diameter of the operation channel pipe. The working pipe system can greatly shorten operation time after location of the puncturing locating needle, the dilation tubes are continuously inserted into the operation area, and at last the operation channel tube is inserted into and aligned with the operation area, and compared with time of the traditional operation, the time is shortened by 1 hour. The working pipe system has the advantages that the working pipe system is easy to operate, the operation wound is small, the damage to bones and muscles during the operation is reduced, and the working pipe system facilitates postoperative rehabilitation and reduces complication.
Description
Technical field
This utility model relates to medical instruments field, particularly the other center of a kind of spinal column keyhole approach service pipe system.
Background technology
When spinal operation, remember tissue influence's operation technique such as muscle, blood vessel, trachea, esophagus, thyroid of both sides for fear of knife-edge part, need organizing glass and strut knife-edge part spinal column both sides, a kind of jaw type dilator at present commonly used, this dilator need be positioned over the left and right sides of remembeing operative site respectively or up and down in the entry at two ends when using, rely on the operation of operation that tissue is separated to both sides, expose vertebral body so that perform the operation, because the blade strength that struts is not high.The blade far-end has cohesion trend, the method that struts is single, because need at least two dilators just can play effect, scalpel edge needs longer, not only increases the patient suffering, and postoperative is difficult for healing, it is not good enough that the art district struts effect, influences the visual field, the operation technique complexity, increase operation risk, do not meet minimally invasive spinal surgery operation theory.Use domestic and international similar service aisle diameter generally bigger in addition clinically, use the back to paravertebral muscles, particularly the multifidi equivalent damage is bigger, and expensive, increases the corrective surgery cost.
Summary of the invention
It is a kind of easy to operate that the purpose of this utility model is to provide, good stability, the good other center of the spinal column keyhole approach service pipe system of location, art district rearward vision.
The purpose of this utility model is achieved in that it comprises operation path pipe, the puncture positioning needle of fixture, band fixed card slot, the convergent divergent channel that one cover diameter increases successively, the operation path pipe is fixed on the fixture by fixed card slot, the specification of convergent divergent channel is that the pipe medial wall diameter of upper level convergent divergent channel equals next stage convergent divergent channel lateral wall diameter, and the convergent divergent channel external diameter of maximum one-level equals the internal diameter of operation path pipe.
Advantage of the present utility model is: 1, simple to operate, operating time shortens significantly, position by the puncture positioning needle, constantly insert convergent divergent channel afterwards and insert the operation path pipe at last and the operation path pipe is carried out para-position and get final product, shortened 1 hour than the traditional operation time.2, operation wound is little, reduces the damage of skeleton, muscle in the operation, helps postoperative rehabilitation, reduces complication.3. this service aisle external diameter is restricted to 1.42cm, has avoided existing heavy caliber service aisle (external diameter is all greater than more than the 2cm) damage multifidi, and to distance between the spinous process, the former can better protect multifidi and nerve according to adult's year articular process medial surface.
