It includes a column, with a handle fixed to the end of the column. Several sets of implantation seats are fixed to the surface of the handle, and interconnected implantation needle channels are formed in both the implantation seats and the middle of the column. A positioning groove is formed on one end of the handle. The outwardly inclined arc of the implantation needle channel pulls the flexible non-metallic needle in its movement direction. The inclination angle of the flexible non-metallic needle varies from 0° to 90°, improving the ease of use for the operator and facilitating the fixation of the flexible non-metallic needle, thus improving the stability of the flexible non-metallic needle during use.

Description

Technical Field

[0001] This utility model belongs to the technical field of positioning and guiding devices, and particularly relates to a positioning and guiding device for soft needles used in radiotherapy after implantation of gynecologic tumors. Background Technology

[0002] When medical staff need to treat cervical cancer patients, they usually use an implantation needle to carry the treatment tool to the lesion site. To facilitate the positioning of the implantation needle, medical staff may use a locator inserted into the patient's vagina. The operator then inserts the implantation needle into the locator, allowing the locator to position the implantation needle. However, when using a locator for gynecologic oncology brachytherapy, there are not only rigid metal implantation needles but also flexible non-metallic needles. Because the insertion hole of a general locator has a large bend at the end, it may be difficult for the operator to use the flexible non-metallic needle conveniently, which may be inconvenient for the operator. Therefore, we propose a soft needle positioning and guiding device for gynecologic oncology brachytherapy. Utility Model Content

[0003] This utility model provides a positioning and guiding device for soft needles used in radiotherapy after implantation in gynecologic tumors. By setting the needle path to be inclined outward in an arc, the angle of inclination of the flexible non-metallic needle varies from 0° to 90° when using the flexible non-metallic needle, which improves the ease of use for the operator.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning and guiding device for radiotherapy soft needles after implantation in gynecologic tumors, comprising a column, a handle fixed to the end of the column, and several sets of implantation seats fixed to the surface of the handle, and implantation needle channels that are interconnected are opened in the middle of the implantation seats and the column, and a positioning groove is opened at one end of the handle.

[0005] Furthermore, a positioning groove is provided on one end of the grip, and all positioning grooves are set as rectangular grooves.

[0006] Furthermore, each of the insertion bases has a limiting groove on its surface, and the limiting groove is set as an arc-shaped groove. A hanging block is symmetrically fixed to one end of the handle.

[0007] Furthermore, the ends of the insertion needle channels on both sides of the column are designed to be curved and tilted outwards.

[0008] The beneficial effects of this utility model are:

[0009] 1. This gynecological tumor implantation radiotherapy soft needle positioning and guiding device is equipped with an implantation needle channel. The implantation needle channel is designed to be curved outwards. When the flexible non-metallic needle slides in the implantation needle channel, the curved outwards channel pulls the flexible non-metallic needle in the direction of movement. The angle of inclination of the flexible non-metallic needle varies from 0° to 90°, which improves the ease of use for the operator.

[0010] 2. The soft needle positioning and guiding device for radiotherapy after implantation of gynecologic tumors is equipped with a hanging block, an implantation seat, and a limiting groove. The operator inserts the flexible non-metallic needle into the implantation needle channel through the implantation seat. Then, the operator binds the rubber band to the surface of the implantation seat and the rubber band to the limiting groove, which facilitates the operator to fix the flexible non-metallic needle and improves the stability of the flexible non-metallic needle during use.

[0018] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings.

[0019] Example:

[0020] Please see Figure 1 - Figure 5The device for positioning and guiding radiotherapy soft needles after implantation in gynecologic tumors includes a column 1. A handle 3 is heat-fused to the end of the column 1, and several sets of implantation seats 5 are heat-fused to the surface of the handle 3. Both the implantation seats 5 and the column 1 have interconnected implantation needle channels 2. A positioning groove 7 is formed on one side of the handle 3, and all positioning grooves 7 are rectangular recesses. The ends of the implantation needle channels 2 on both sides of the column 1 are curved outwards. When in use, the operator inserts the column 1 into the patient's vagina, then moves the implantation needle through the implantation seat 5. The needle is inserted into the insertion channel 2 and moves to the patient's lesion through the insertion channel 2 to treat the lesion. The six sets of insertion channels 2 set vertically are parallel to the center line of the column 1 to prevent accidental entry into the urethra and rectum during insertion. The six sets of channels set on the left and right sides are curved outwards. When using a flexible non-metallic needle, the flexible non-metallic needle can move along the curved outwards needle channel 2. When using a flexible non-metallic needle, the angle of inclination of the flexible non-metallic needle varies from 0° to 90°, which is convenient for the operator to use.

[0021] In other embodiments, the surface of the implantation base 5 is provided with a limiting groove 6, and the limiting groove 6 is set as an arc-shaped groove. A hanging block 4 is symmetrically heat-fused to one end of the handle 3. When the operator inserts the implantation needle into the implantation needle channel 2, the operator wraps the rubber band around the surface of the implantation base 5 and wraps the rubber band around the limiting groove 6 to fix the implantation needle in the implantation needle channel 2, so as to facilitate the medical staff to fix the implantation needle.

[0022] Although 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
