Description

Technical Field

[0001] The utility model belongs to the technical field of positioners, in particular to a positioner for intracavitary radiotherapy of gynecological tumors. Background Art

[0002] When medical staff need to perform gynecological cervical cancer treatment on patients, they may use a locator to insert into the patient's vagina. The operator then inserts the interpolation needle into the locator to allow the locator to position the interpolation needle. However, when using the locator, since the positioning hole of the general locator is fixed, it may not be possible to adjust the interpolation position, thereby failing to meet the needs of different degrees of paracervical invasion and interstitial radiotherapy. In order to ensure that the interpolation moves stably to the patient's diseased area, we propose a gynecological tumor intracavitary radiotherapy locator. Utility Model Content

[0003] The utility model provides a gynecological tumor intracavitary radiotherapy positioner, which forms oblique needle paths on both sides of the column and the fixed ring by opening interpolation holes that communicate with the interpolation tube, thereby meeting the needs of different degrees of parauterine invasion and interstitial radiotherapy.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a gynecological tumor intracavitary radiotherapy positioner, comprising a column, wherein an extension tube and a fixing ring are fixed to the ends of both sides of the column respectively, and a plurality of groups of end heads are fixed in a ring shape on the surface of the fixing ring, and an interpolation port is opened in the middle of the end head, an interpolation tube is opened in the middle of the column and is interconnected with the interpolation port, and the ends of the interpolation tube are connected to interpolation holes opened around the surface of the extension tube.

[0005] Furthermore, the interpolation tubes are all spiral-shaped.

[0006] Furthermore, the extension tube is configured to be in an arc shape.

[0007] Furthermore, an interpolation hole is provided on one side where the extension tube and the column are connected to each other, and several groups of opposite interpolation holes are all configured as small holes.

[0008] Furthermore, the extension tube is configured as a groove.

[0009] Furthermore, the interpolation holes are all configured as circular holes that are smaller than the opening of the interpolation port.

[0010] The beneficial effects of the utility model are:

[0011] 1. This gynecological tumor intracavitary radiotherapy positioner has interpolation holes on both sides of the column and the fixed ring that communicate with the interpolation tube, so that oblique needle channels are formed on both sides of the column. The angle-adjustable oblique needle channels on both sides can meet the needs of different degrees of parauterine invasion and interstitial radiotherapy.

[0012] 2. The gynecological tumor intracavitary radiotherapy localizer has channels in the inner circle, which are through-going needle channels, and channels in the outer circle on the left and right sides, totaling through-going oblique needle channels, to meet the needs of three-dimensional afterloading intracavitary combined with interstitial radiotherapy dose prescription for gynecological tumor lesions of different locations and shapes.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0025] Example 1:

[0026] See also Figure 1 - Figure 5, a gynecological tumor intracavitary radiotherapy positioner includes a column 1, an extension tube 2 and a fixing ring 3 are fixed to the ends of both sides of the column 1, the extension tube 2 is set to an arc shape, and a plurality of groups of end heads 5 are fixed to the surface of the extension tube 2 in an annular manner, and an interpolation port 7 is opened in the middle of the end head 5, an interpolation tube 4 is opened in the middle of the column 1 and is connected to the interpolation port 7, and the end of the interpolation tube 4 is connected to the interpolation hole 6 opened around the surface of the extension tube 2, and the interpolation tube 4 is spiral. When the operator is performing diagnosis and treatment, the operator first inserts the column 1 into the patient's vagina, and then the operator takes it. Interpolation needle, align the interpolation needle and the interpolation port 7 with each other, then the operator inserts the interpolation needle into the interpolation port 7, and the interpolation needle moves along the interpolation port 7 into the interpolation tube 4, and moves out of the interpolation hole 6 through the interpolation tube 4, so that the interpolation needle moves to the patient's diseased area, thereby treating the patient's diseased area. At the same time, the twelve channels in the inner circle are through-going insertion needle channels, and are equipped with three on each of the outer circles on the left and right sides, totaling six through-going oblique needle channels, which meet the needs of different locations, shapes, and three-dimensional post-loading intracavitary combined interstitial insertion radiotherapy dose prescriptions for gynecological tumor lesions.

[0027] In other embodiments, the interpolation holes 6 are opened on one side where the extension tube 2 and the column 1 are connected to each other, and several groups of opposite interpolation holes 6 are all set as small holes. By setting the interpolation holes 6 opened on the side where the extension tube 2 and the column 1 are connected to each other as small holes, the operator cannot pass through the interpolation holes 6, and the interpolation needle cannot pass through the interpolation holes 6, and the outer ring insertion needle channels are changed to six groups.

[0028] Example 2:

[0029] See also Figure 6 - Figure 9 The invention relates to a gynecological tumor intracavitary radiotherapy localizer, comprising a column 1, an extension tube 2 and a fixing ring 3 are fixed to the ends of the column 1 on both sides respectively, the extension tube 2 is arranged to be grooved, and a plurality of groups of end heads 5 are fixed in an annular manner on the surface of the extension tube 2, and an interpolation port 7 is opened in the middle of the end head 5, an interpolation tube 4 is opened in the middle of the column 1 and is interconnected with the interpolation port 7, and the end of the interpolation tube 4 is connected with an interpolation hole 6 opened around the surface of the extension tube 2, and the interpolation tube 4 is spiral-shaped. The operator aligns the interpolation needle with the interpolation port 7 opened in the middle of the end head 5, and then pushes the interpolation needle to move the interpolation needle through the interpolation port 7 into the interpolation tube 4, and the interpolation needle moves along the interpolation tube 4 to the interpolation hole 6, thereby performing close-range treatment on the patient's lesion, avoiding the gap between the interpolation needle and the lesion due to the semicircular shape of the extension tube 2, which makes it impossible to perform effective diagnosis and treatment on the lesion, thereby facilitating three-dimensional post-loading close-range intracavitary radiotherapy for gynecological tumors.

[0030] In other embodiments, the interpolation holes 6 are all set to be circular holes smaller than the opening of the interpolation port 7. Since the through hole set in the interpolation hole 6 is smaller than the circular hole at the opening of the interpolation port 7, the operator can move to the interpolation hole 6 and move the interpolation needle to the surface of the cylinder 1, but the interpolation needle cannot pass through the interpolation hole 6. By preventing the interpolation needle from passing through the interpolation hole 6, the operator is prevented from injuring the patient with the interpolation needle when using it, and the insertion needle can be prevented from accidentally entering the bladder and rectum.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
