具体实施方式 detailed description

[0026] 下面结合附图对本发明作进一步描述。 [0026] The following drawings in conjunction with the present invention will be further described.

[0027] 实施例1,经皮肾穿刺造瘘是临床上经皮肾钬激光或气压弹道和超声碎石等目前广泛开展的微创取石手术的先决条件,只有率先建立了经皮肾通道,才能通过这一通道进行下一步碎石手术,临床医生形象的把这一步骤说成:通道一建成,手术就相当做了一半了。 [0027] Example 1, the percutaneous nephrostomy is a prerequisite stone surgery through clinical percutaneous nephrolithotomy holmium laser or ultrasonic lithotripsy pneumatic lithotripsy and minimally invasive widely carried out, only the lead in establishing a percutaneous renal access, through this channel to be the next gravel operation, the image of the clinicians say this step: a channel is completed, the operation is quite a half-done. 由此可见其重要性和难度。 This shows the importance and difficulty. 传统的方法是先在B超引导下穿刺针进入肾盂,成功后由穿刺针置入一软的斑马导丝;拔出穿刺针留置导丝于肾盂内,再取筋膜扩张器由小到大扩入肾盂。 The traditional method is to needle into the pelvis in the B-guided, after a successful implantation of a soft zebra guidewire of the puncture needle; pull out the needle indwelling guidewire in the renal pelvis, then take fascial dilator ascending expansion into the renal pelvis. 正常情况下,积水也多斑马导丝在肾盂内留置越多,导丝引导的作用越好,不容易脱出肾盂。 Normally, water is also more zebra indwelling guidewire in the renal pelvis, the better the effect of guide wire is not readily released pelvis. 但临床上经常有结石病人积水不多,甚至没有积水,肾盂空间小就难于置入斑马导丝留置,造成扩张通道困难。 But clinically stones often have little water, not even water, it is difficult to put into a small space pelvis zebra guide wire placement, resulting in the expansion of the channel difficult. 本发明的可套入性筋膜扩张器即径向脱出扩张器与传统的扩张法完全不同:1、借助穿刺针直接在套在针上穿刺,位置更固定。 Can fit into the fascial dilator of the present invention, i.e., radial expansion with conventional extrusion expansion method is completely different: 1, by means of the puncture needle directly set in the puncturing needle, a more permanent location. 无弯曲,无导丝脱落等。 Without bending, the guide wire without falling off. 2、扩张过程随时经由助手推水了解把握穿刺针确定一直位于肾盂内,有效防止扩到肾盂对侧。 2, the expansion process at any time to push the water through the assistant understand conventional needle has been located in the pelvis to determine, effectively preventing the expansion of the renal pelvis to the opposite side.

[0028] 实施例2,扩张管做成纵向开坑槽,利于在完成穿刺后方便留置斑马导线在肾盂内,使手术安全可靠,穿孔机刺针和斑马导线留置在肾盂内位置适中,到位而不越位,不会穿刺到对侧的血管而导致大出血,安全可靠,方便实用。 [0028] Example 2, made of longitudinally expanded tubular open pits, after the completion of the puncture facilitates easy placement in the renal pelvis Zebra conductor, safe and reliable operation, and the lancet piercing machine wire zebra moderate indwelling position within the renal pelvis, in place without offside, not to puncture the opposite side of the blood vessel and cause bleeding, safe, reliable, convenient and practical. 扩张器做成径向脱出扩张器体(4),径向脱出扩张器体(4 )轴向上开坑槽口为径向脱出扩张器开坑口( 6 ),径向脱出扩张器体 Made emerge radially expandable dilator body (4), coming out radially expandable body (4) open pit prolapse dilator open pit (6) is a radially axial, radial expansion body prolapse

(4)的内孔通孔为径向脱出扩张器锥形通孔(7)、径向脱出扩张器直通孔(8),径向脱出扩张器开坑口(6)底下相通于径向脱出扩张器锥形通孔(7)和径向脱出扩张器直通孔(8)。 (4) a bore through hole coming out radially expandable cone through hole (7), a radial through-bore extrusion dilator (8), open pit dilator radial extrusion (6) coming out radially expandable under communication cone through hole (7) and the radial through-bore extrusion dilator (8). 径向脱出扩张器锥形通孔(7)和径向脱出扩张器直通孔(8)孔径比穿刺留置通管体(11)的外径略大,是动配合,可轴向串动,也可相互转动。 Emerge radially expandable cone through hole (7) and the radial through-bore extrusion dilator (8) through the aperture ratio indwelling tube (11) is slightly larger outer diameter, it is moving with, the axial vibration, and mutually rotatable. 穿刺留置通管体(11)内孔穿刺留置通孔 Through the indwelling tube (11) through the bore hole indwelling

(10)孔径比穿刺针体(14)略大,是动配合,可轴向活动,也可相互转动。 (10) an aperture (14) is slightly larger than the needle body is moving with, axially activity, may be mutually rotatable. 斑马导线体(20)和斑马导线软线段(19)外径比穿刺留置通管体(11)的穿刺留置通孔(10)略小,可轴向串动,也可相互转动。 Zebra conductor (20) and a soft segment Zebra conductor (19) than the outer diameter of the indwelling indwelling tube through the through-hole (11) (10) is slightly smaller axially movable string, can be mutually rotatable. 安装使用时穿刺针体(14)穿透通过穿刺留置通管体(11)的穿刺留置通孔(10),穿刺留置通管体(11)穿透通过径向脱出扩张器开坑口(6)底下的径向脱出扩张器锥形通孔(7),和径向脱出扩张器直通孔(8)并进入体内,穿刺成功后斑马导线软线段(19)和斑马导线体(20)穿透通过穿刺留置通管体(11)的穿刺留置通孔(10)进入肾盂,之后轴向拉出径向脱出扩张器体(4),并从经向上通过径向脱出扩张器开坑口(6),把径向脱出扩张器体(4)脱出穿刺留置通管体(11),使之相互分离,这时已由径向脱出扩张器体(4)扩容出一个洞让手术器具顺利方便、安全、准确进入体内做手术,达到微创手术成功。 Mounting the puncture needle (14) penetrates through the indwelling through hole (10) through the indwelling tube (11) in use, through the indwelling tube (11) penetrates the dilator apart by radial extrusion pit (6) radial expansion cone coming out under the through hole (7), and a radial through-bore extrusion dilator (8) and into the body, after successful puncture soft segment zebra conductor (19) and the zebra conductor (20) penetrating through indwelling indwelling through hole (10) through the tube (11) into the pelvis, then pulled out axially coming out radially expandable body (4), and open pit (6) from coming out through the stent by a radial direction, the radially expandable body extrusion (4) coming out through the indwelling tube (11), separated from each other so that, by the time coming out radially expandable body (4) expansion of a surgical instrument so that a smooth hole convenient, safe, accurately into the body for surgery, minimally invasive surgery to achieve success.
