Embodiment 2

[0068] A stuffing-free source applicator for gynecological intracavity radiotherapy. This embodiment is a replacement for the locking device in Embodiment 1.

[0069] Such as Figure 5 , Figure 6 , The non-tampon source applicator for gynecological intracavity radiotherapy in this embodiment adopts a locking device of a locking rod type. The lever-type locking device includes a toothed lever 60 and an elastic ferrule 61 .

[0070] The tooth-shaped clamping rod is a rod with a square cross section. A plurality of evenly arranged saw-shaped teeth 62 are arranged on one side of the tooth-shaped clamping rod. 64, the positioning ball protrudes toward the front end of the toothed clamping rod, and scales 66 are provided on the two sides of the toothed clamping rod perpendicular to the side faces provided with saw-shaped teeth.

[0071]Elastic ferrule is a square sleeve body, and elastic ferrule is provided with the square hole that slides with tooth-shaped clamp bar, and one si...

Embodiment 3

[0079] A stuffing-free source applicator for gynecological intracavity radiotherapy. This embodiment is a replacement for the locking device in Embodiment 1.

[0080] Such as Figure 7 , Figure 8 , the locking device of the non-tampon applicator for gynecological intracavity radiotherapy in this embodiment uses a nylon cable tie.

[0081] A vault locking head 24 is provided at the tail end of the vault guide block, and a tape groove 26 is provided on the outer surface of the vault locking head. A vaginal locking head 34 is provided at the tail end of the vaginal support block, and a cassette groove 36 is provided on the outer surface of the vaginal locking head.

[0082] After the vault guide block and the vagina support block are in place, use a nylon cable tie 70 to bind the two vault guide blocks through the cassette slot of the vault locking head, thereby locking the vault guide block; use a nylon cable tie to pass through the cassette slot of the vagina locking head T...

Abstract

The invention relates to a filling-free source applicator for gynecological intracavity radiotherapy. The filling-free source applicator comprises a uterine cavity catheter and two vault catheters. The uterine cavity catheter is mounted in a catheter seat, two vault guide blocks are respectively arranged on the left side and the right side of the catheter seat, and two vagina support blocks are respectively arranged on the front side and the rear side of the catheter seat; the two vault catheters are respectively mounted on the vault guide blocks on the left side and the right side of the catheter seat, two ends of each vault guide block can carry out lever rotation along the directions perpendicular to the axis of the uterine cavity catheter, and two ends of each vagina support block can carry out lever rotation along the directions perpendicular to the axis of the uterine cavity catheter. The filling-free source applicator has the advantages that the filling-free source applicator is provided with the vault guide blocks and the vagina support blocks which can be distracted, the vault catheters can be repositioned and fixedly positioned by the aid of the vault guide blocks, and the distances from the filling-free source applicator to the urinary bladders and the rectums of patients can be extended by the vagina support blocks by means of distraction; gauze filling can be omitted, accordingly, the filling-free source applicator is convenient to operate, stable and reliable effects can be realized, the disposal time can be obviously shortened, and suffering can be relieved for the patients.

Description

technical field [0001] The invention belongs to a gynecological radiotherapy source applicator, in particular to a stuffing-free source applicator for gynecological intracavity radiotherapy. Background technique [0002] The applicator catheter for gynecological radiotherapy includes a uterine catheter and two dome catheters, and a positioning frame is used to lock the relative positions of the three catheters; when in use, the uterine catheter extends into the uterine cavity, and the tops of the two dome catheters are placed The vault at the bottom of the vagina. After the uterine catheter and the two dome catheters are in place, it is necessary to fix the position of the uterine catheter and dome catheter to prevent them from moving during radiotherapy. The rear end spreads the distance between the applicator and the rectum. Adopt the method for stuffing gauze in vagina at present to realize above-mentioned purpose. The disadvantage of this method is that the operation ...
