The specific embodiment
For technical problem, technical scheme and advantage that embodiments of the invention will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
Embodiments of the invention to fascia dilator in the prior art to thrust the degree of depth accurate inadequately; The problem that delays operating time, increase operation risk; A kind of fascia dilator is provided; Can thrust degree of depth limitation function for the fascia dilator increase, can improve the speed of operation of user, excessive bur because of too firmly causing in the time of can effectively avoiding expanding more tough and tensile organizing again.
Be illustrated in figure 1 as the structural representation of fascia dilator of the prior art, fascia dilator of the prior art includes only convergent divergent channel 1, does not possess the degree of depth of thrusting limitation function, like this fascia dilator to thrust the degree of depth just accurate inadequately.
Shown in Figure 2 is the structural representation of the fascia dilator of the embodiment of the invention; The fascia dilator of present embodiment comprises convergent divergent channel 1, and convergent divergent channel 1 front end is tip, and main part is cylindric for evenly; The fascia dilator of present embodiment also comprises: be sheathed on the convergent divergent channel 1, the sleeve pipe 2 of an even hollow; Wherein, the end, rear end of the terminal of sleeve pipe 2 and convergent divergent channel 1 coincides, and the length of sleeve pipe 2 is confirmed according to treatment position; The length of sleeve pipe 2 is the degree of depth of thrusting that the length of convergent divergent channel 1 deducts convergent divergent channel, through sleeve pipe 2 can so that convergent divergent channel 1 to thrust the degree of depth limited at the front end of sleeve pipe 2.
Further, sleeve pipe 2 surfaces can also be provided with the graduation mark that thrusts the degree of depth of indication convergent divergent channel along its length, utilize this graduation mark doctor can accurately grasp the degree of depth of thrusting of fascia dilator.The external diameter of the internal diameter of sleeve pipe 2 and convergent divergent channel 1 is suitable, and sleeve pipe 2 closely is set on the convergent divergent channel 1.
Particularly, the thickness of sleeve pipe 2 is less than 2mm.
The material of sleeve pipe 2 is tailorable material, can be nonmetallic materials, and particularly, the material of sleeve pipe 2 can be politef or polypropylene.
Below in conjunction with Fig. 3 the method for using of embodiment of the invention fascia dilator is described in detail.
In the existing microtrauma puncture operation; With the PCN operation is example; The doctor is at first thrust the puncture needle of a cover hollow in the human body under the supervision of image documentation equipment; Selected treatment position before the through human kidney art, the puncture needle of every cover hollow comprises the pin and the outer casing needle of puncture needle endoporus, the puncture needle outer setting has graduation mark.In the existing operation process, the doctor writes down the palpus paracentesis depth according to the outside scale value of puncture needle; Afterwards the pin of puncture needle endoporus is extracted, stayed outer casing needle, at this moment seal wire is penetrated through treatment position from puncture needle inside; Then outer casing needle is extracted, lowest calibre convergent divergent channel through area for treatment in seal wire thrusts human body, generally speaking; The doctor will expand more than 4 times at the convergent divergent channel with different thicknesses under the identical degree of depth; The doctor should be noted that the expansion degree of depth in each expansion, and guaranteeing to expand the degree of depth is the palpus paracentesis depth of noting, and because seal wire does not possess the function of degree of depth restriction; Therefore when expanding, the risk of deepening wound is arranged with convergent divergent channel.
