Description

Technical Field

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

[0002] When the operator inserts the fixator into the vagina, and then inserts the interpolation needle into the fixator, if the operator pushes the interpolation needle to move too fast in the fixator, after the interpolation needle passes through the fixator, the interpolation needle may pierce into the patient's diseased tissue, thereby causing secondary injury to the patient. For this reason, we propose a round flat-head positioner for intracavitary radiotherapy of gynecological tumors. Utility Model Content

[0003] The utility model provides a round flat head positioner for intracavitary radiotherapy of gynecological tumors. The end of an interpolation tube is set at an angle to prevent an insertion needle from moving out of the end of the interpolation tube, thereby ensuring that the insertion needle will not pierce tissue during intracavitary radiotherapy.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a round flat head positioner for intracavitary radiotherapy of gynecological tumors, comprising a column and a fixed ring, a fixed ring is fixed to the end of the column, and a plurality of groups of limiting openings are opened in the middle of the fixed ring, an interpolation opening is opened in the middle of the limiting opening, and the end of the interpolation opening is connected to an interpolation tube opened in the column, guide grooves are symmetrically opened on both sides of the fixed ring, and grip rings are symmetrically opened on both ends of the fixed ring.

[0005] Furthermore, a fixing block is fixed on one side of the end of the fixing ring, and a fixing rod groove is opened in the middle of the fixing block, and a limiting rod is symmetrically fixed on the side wall of the fixing block.

[0006] Furthermore, the fixing rod groove is arranged outside the annular fixing ring.

[0007] Furthermore, the side walls of the limiting opening are all provided with guide columns.

[0008] Furthermore, the end of the interpolation tube is arranged to be inclined so that the end of the interpolation tube forms an angle.

[0009] The beneficial effects of the utility model are:

[0010] 1. The circular flat head positioner for intracavitary radiotherapy of gynecological tumors is provided with an interpolation tube. By setting the end of the interpolation tube to an angle of 30° to 60°, the operator is prevented from inserting the interpolation needle into the interpolation tube and preventing the interpolation needle from moving out of the end of the interpolation tube, thereby ensuring that the interpolation needle will not pierce the tissue during intracavitary radiotherapy.

[0011] 2. The circular flat head positioner for intracavitary radiotherapy of gynecological tumors is provided with a fixing rod groove. By arranging the fixing rod groove on the outside of the fixing ring, interference between the fixing rod and the implantation operation at the 6 o'clock direction during the implantation process is avoided.

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0020] Example:

[0021] See also Figure 1 - Figure 5, a round flat head positioner for intracavitary radiotherapy of gynecological tumors, including a column 1 and a fixing ring 2, the end of the column 1 is hot-melt-bonded with the fixing ring 2, and a plurality of groups of limiting openings 4 are opened in the middle of the fixing ring 2, an interpolation opening 6 is opened in the middle of the limiting opening 4, and the end of the interpolation opening 6 is connected with an interpolation tube 5 opened in the column 1, guide grooves 9 are symmetrically opened on both sides of the fixing ring 2, and the end of the interpolation tube 5 is set to be inclined so that the end of the interpolation tube 5 forms an angle, and grip rings 10 are symmetrically opened on both sides of the fixing ring 2, and the angle formed by the end of the interpolation tube 5 is between 30° and 60°. When the operator needs to treat the patient, the operator inserts the column 1 into the patient's vagina, and then the operator inserts the interpolation needle into the limiting opening 4 through the interpolation opening 6, and moves along the direction of the limiting opening 4 into the interpolation tube 5, and then the interpolation needle moves along the interpolation tube 5 to insert the interpolation needle into the column The body 1 is provided with an angle at the end of the interpolation tube 5, and when the interpolation needle moves to the angle set at the end of the interpolation tube 5, the angle set at the end of the interpolation tube 5 restricts the interpolation needle to prevent the interpolation needle from continuing to move, so that the interpolation needle is used to treat the patient's diseased part. Moreover, since the end of the interpolation tube 5 is set at an angle, the interpolation needle is prevented from moving out from the end of the interpolation tube 5, ensuring that the interpolation needle will not injure the tissue during intracavitary radiotherapy. The angle at the end of the interpolation tube 5 is set to 30° to 60 degrees, which not only ensures that the interpolation needle will not penetrate and injure the tissue, but also ensures that during the 3D printing process, the curved channel does not need to add support, reducing the post-processing of removing the support. The design of this angle is also convenient for the use of SLA printing technology, and no solidified liquid resin flows out, and during the post-processing of 3D printed parts, the liquid resin adhering to the channel wall in the channel is cleaned and flows out.

[0022] In other embodiments, a fixing block 7 is hot-melt bonded to one side of the end of the fixing ring 2, and a fixing rod groove 11 is opened in the middle of the fixing block 7, and the fixing rod groove 11 is opened on the outside of the annular fixing ring 2, and a limiting rod 8 is symmetrically hot-melt bonded to the side wall of the fixing block 7. When in use, the operator inserts the fixing rod into the fixing rod groove 11 to fix the fixing rod on the fixing block 7, and by opening the fixing rod groove 11 on the outside of the fixing ring 2 and offsetting it downward, the operator is prevented from inserting the fixing rod into the fixing rod groove 11. After the fixing rod is installed on the fixing ring 2, interference between the fixing rod and the implantation operation at the 6 o'clock direction is avoided during the implantation process, and the limiting rod 8 is fixed on both sides of the fixing block 7, which is convenient for the operator to wrap the rubber band around the surface of the limiting rod 8, thereby reducing the separation of the fixing rod and the locator due to body twisting during the patient's radiotherapy.

[0023] In other embodiments, guide posts 3 are provided on the side walls of the limiting opening 4 , and guide posts 3 are provided on the surface of the limiting opening 4 , so that the operator can easily tie the rubber band on the limiting opening 4 .

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
