[0019] 实施例一: [0019] Example a:

如图1至图4,一种施源驻留器阴道口固定装置,在妇科放疗中将施源驻留器10在阴道口51部位固定;施源驻留器的导管11通过阴道52插入子宫宫腔53中,在施源驻留器的导管上设有定位块12,定位块顶在宫颈口54处。 1 to 4 A is applied to the source resides vagina fixing means 10 is applied to the source dwell portion 51 fixed to the vagina in a gynecological radiotherapy; source application resident catheter 11 is inserted into the uterus through the vagina 52 53 in the uterine cavity, with the positioning block 12, block 54 is positioned cervix at the top of the source application resides on the catheter's.

[0020] 施源驻留器阴道口固定装置包括固定腰带20、固定拉带30、固定卡头40 ;固定卡头固定安装在所述施源驻留器上,固定卡头位于阴道口处。 [0020] Vaginal administration source resides opening means includes a stationary fixing belt 20, the fixing belt 30 to pull, the chuck 40 is fixed; fixed chuck fixedly mounted on the source application resides, a fixed chuck located at the vaginal opening.

[0021] 固定腰带是束紧在患者腰部的腰带,在固定腰带的前腹部中间位置上设有系紧扣23,系紧扣是尼龙搭扣;固定腰带的前腹部两侧各设有一个连接扣21,固定腰带的连接扣是尼龙搭扣的尼龙钩带。 [0021] The belt is fixed to the patient's waist tightening the belt, with fastening system 23, based on Velcro fastening a front abdominal belt is fixed on an intermediate position; side of the front abdominal fixing belt provided with a respective connection button 21, a fixed connection belt buckle is nylon Velcro hook tape.

[0022] 固定拉带有两条,两条固定拉带的一端固定连接在固定腰带的后腰部22,两条固定拉带交叉环绕所述固定卡头、向阴道内方向拉紧固定卡头;两条固定拉带的另一端是扣接端31,固定拉带的扣接端设有与固定腰带的尼龙搭扣对应的尼龙绒带,两条固定拉带的扣接端分别与固定腰带的两个连接扣连接,使固定拉带束紧在固定腰带上。 [0022] with two fixed pull, two fixed end fixedly connected to the tear tape rear waist fixing belt 22, two fixed drawstring around the intersection of the fixed chuck, the chuck is fixed to the tensioning direction of the vagina; two pull the other end with a fastening end 31 is fixed to the draw tape end is provided with the fixed fastening belt corresponding Velcro nylon velvet ribbon, two fixed drawstring ends are fixed fastening belt two connecting snap connection, the fixing belt tightening pull on the fixing belt.

[0023] 固定卡头需要在施源驻留器送入阴道后再固定到施源驻留器的导管上,因此固定卡头不能从施源驻留器的导管的端头套入,要从施源驻留器的导管的两侧固定到施源驻留器的导管上。 [0023] The fixed chuck requires administered into the vagina before the source resides is secured to the catheter applied to the source's residence, thus fixing the chuck end of the catheter can not be applied to the source into a headgear from the resident device, from Shi source residing on both sides of the conduit is secured to the catheter applied to the source's residence.

[0024] 固定卡头包括卡头座41、卡头锁紧块42和锁紧螺钉43。 [0024] The fixed chuck comprises a chuck holder 41, chuck 42 and the locking block 43 a locking screw.

[0025] 卡头座的一端设有套筒形的导管卡套411,导管卡套的内孔设有锁紧螺纹412,从导管卡套的端头沿轴向设有伸入导管卡套内的导管卡槽413,导管卡槽的宽度对应于所述施源驻留器导管的直径,导管卡槽在径向贯通导管卡套,导管卡槽的底部是与施源驻留器导管的外径对应的圆弧形415。 [0025] One end of the head holder is provided with a ferrule sleeve-shaped conduit 411, the conduit of the ferrule bore is provided with a locking screw 412, with sleeve extending into the catheter from the catheter card end of the ferrule axially the slot 413 of the catheter, the catheter slot width corresponding to the diameter of the source application resides in the catheter, the catheter through the catheter ferrule slot in the radial direction, the bottom slot of the catheter is a catheter application resides outside source 415 corresponding to the arcuate path. 在卡头座设有拉带槽口414。 In the header card slot 414 is provided with the tear tape.

[0026] 卡头锁紧块是套筒形。 [0026] A chuck is sleeve-shaped locking block. 卡头锁紧块的一端设有卡头套孔421,卡头锁紧块的另一端设有紧固孔422,紧固孔与卡头套孔同轴并与卡头套孔连通;在卡头锁紧块设有卡头套孔一端的端面设有导管锁紧槽423,导管锁紧槽是与施源驻留器导管的外径对应的圆弧形;在卡头锁紧块上设有拉带槽口424。 One end of the locking block is provided with a chuck hole chuck sleeve 421, the other end of the chuck locking block is provided with a fastening hole 422, a fastening hole coaxially with the chuck sleeve and the hole communicates with the chuck sleeve bore; locked chuck block end faces of the chuck sleeve is provided with an end hole catheter is provided with a locking groove 423, is applied to the locking groove conduit source resides catheter corresponding arcuate outer diameter; provided with pull grooves on the chuck locking block port 424.

[0027] 本实施例中的锁紧螺钉是一颗内六方头螺钉。 [0027] The locking screw of the present embodiment is the embodiment of a hexagonal-head screws.

[0028] 卡头锁紧块通过卡头套孔以滑动配合套装在卡头座的导管卡套的外径上,所述锁紧螺钉穿过卡头锁紧块的紧固孔与卡头座的导管卡套的锁紧螺纹连接,锁紧螺钉旋紧卡头锁紧块,卡头座的导管卡槽和卡头锁紧块的导管锁紧槽从径向压紧施源驻留器的导管,将固定卡头固定在施源驻留器的导管上。 [0028] The chuck by the chuck sleeve locking hole blocks a sliding fit on the outer diameter set in the card header conduit ferrule, locking the locking screw fastening hole passing through the chuck and the chuck block holder catheter ferrule locking thread connection, a locking screw tightened locking block chuck, chuck holder chuck the locking slot and conduit catheter locking groove radial contact block from the source application's resident conduit the fixing clip applying head is fixed on the catheter's source resides. 由于卡头座的导管卡套设有导管卡槽,导管卡套从端头被分割为两个半弧形,当锁紧螺钉旋入导管卡套内的锁紧螺纹时,端头被分割为两个半弧形的导管卡套会产生向外的涨开变形,在使用一段时间后可能产生螺纹连接失效的故障。 Due to the chuck sleeve holder is provided with a conduit pipe card slot, the ferrule is divided into the catheter from the two ends of the semi-arc, when the locking screw is screwed into a threaded locking sleeve catheter card, it is divided into a tip two semi-circular conduits ferrule outwardly open up the generated deformation, failure of a threaded connection failure may occur after a period of use. 为避免出现这种故障,卡头锁紧块的卡头套孔以滑动配合套装在卡头座的导管卡套的外径上,限制了导管卡套涨开变形,可保证固定卡头工作的可靠性。 To avoid this failure, the chuck sleeve locking chuck hole in a sliding block fitted on the outer diameter of the catheter set of the ferrule chuck holder, limiting the deformation of the catheter to open up the ferrule, may be fixed to the chuck to ensure reliable work sex.

[0029] 卡头座的外形是阶梯轴形状,卡头座在导管卡槽底部的外径dl大于所述导管卡套的外径d2、并与所述卡头锁紧块的卡头套孔端的外径d3相同,如图3所示。 [0029] The header card profile is a stepped shaft shape, the outer diameter dl chuck seat bottom slot is greater than the conduit outer diameter of the catheter ferrule d2, the chuck sleeve bore with said chuck end locking block the same as the outer diameter of d3, as shown in FIG. 3. 这样可以避免施源驻留器的导管承受剪切力,保护施源驻留器导管不受损坏和不发生变形。 This prevents the source application resides is subjected to shear forces in the catheter, the source application resides protected from damage and deformation of the duct occurs.

[0030] 在使用时,将固定腰带通过系紧扣束紧在患者腰部。 [0030] In use, the belt will be fixed by tightening the fastening system at the patient's waist. 将施源驻留器送入患者阴道,使施源驻留器的导管处于准确的治疗位置,并使施源驻留器导管上的定位块顶压在子宫颈端口上。 The reside is administered into the vagina of the patient source, so that the source application resides in an accurate treatment catheter position, the positioning block pressed against the cervix duct and the port is applied to the source resides. 然后将固定卡头在阴道口处固定在施源驻留器的导管上;将两条固定拉带交叉环绕所述固定卡头、向阴道内方向拉紧固定卡头;两条固定拉带的扣接端扣在固定腰带的连接扣上。 The chuck is then fixed at the vaginal opening is fixed to the conduit application's source resides; the two fixing drawstring around the intersection of the fixing chuck, the chuck is fixed tension into the direction of the vagina; two fixed drawstring snap connecting the fixed end of the belt buckle in the buckle. 这样,当患者出现一些体位移动时,施源驻留器仍可保持在阴道内正确的治疗位置,保证了放疗剂量分布的准确性。 Thus, when the patient moves some position, it can be maintained is applied to the source resides in the vagina correct treatment position, to ensure the accuracy of the radiation dose distribution.
