Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of positioners, and in particular relates to a fixing structure of a uterine cavity tube and an implantation needle of a gynecological tumor radiotherapy positioner. Background Art
[0002] When the operator is performing radiotherapy for gynecological tumors, the operator needs to insert the uterine canal and the implant needle into the patient's vagina, so as to move the uterine canal and the implant needle to the patient's affected area, thereby treating the patient's affected area. In order to facilitate the operator to stably move the uterine canal and the implant needle to the patient's affected area, the operator may need to use a locator to position the uterine canal and the implant needle, so as to facilitate the operator to position the uterine canal and the implant needle for use. Therefore, it can be seen that the existing locators basically meet people's practical needs, but the following problems still exist.
[0003] When the operator uses the locator to locate the uterine tube and the implant needle, since there is no fixed structure, after the operator inserts the uterine tube and the implant needle into the patient's diseased area through the implantation hole on the locator, if the operator touches or moves it slightly, the uterine tube and the implant needle may deviate from the patient's diseased area, which may affect the patient's quality. For this reason, we propose a fixed structure for the uterine tube and the implant needle of the gynecological tumor radiotherapy locator. Utility Model Content
[0004] The utility model provides a fixing structure of a uterine cavity tube and an implant needle of a gynecological tumor radiotherapy locator. After an operator inserts the uterine cavity tube and the implant into an implant hole through a guide head, the operator winds a rubber band around the surface of the guide head and pushes the rubber band into a binding groove, so that the rubber band fits with the uterine cavity tube and the implant needle. The binding groove increases the friction between the uterine cavity tube and the implant needle and the guide head, thereby increasing the stability of the uterine cavity tube and the implant needle in the implant hole.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing structure of a uterine cavity tube and an implantation needle of a gynecological tumor radiotherapy locator, comprising a locator body, a plurality of groups of implantation holes are opened in the middle of the locator body, a plurality of groups of guide heads are fixed to one end of the implantation holes, and a plurality of groups of binding grooves are opened in the middle of the guide heads, and a rubber band is inserted in the middle of the binding groove.
[0006] Furthermore, a terminal is provided at an end of the positioner body away from the guide head.
[0007] Furthermore, the end head may be configured as an end surface formed by a combination of a spherical surface, an arc surface and a plane surface, or may be configured as an elliptical cylinder.
[0008] Furthermore, the guide head is tiltedly arranged at the end of the locator body, an insertion hole is passed through the middle of the guide head, and the insertion hole is not arranged in a concentric circle with the guide head.
[0009] Furthermore, the guide head is vertically arranged on the end of the locator body, and an insertion hole is penetrated through the middle of the guide head, and the insertion hole is not arranged in a concentric circle with the guide head.
[0010] The beneficial effects of the utility model are:
[0011] 1. The fixing structure of the uterine cavity tube and the implantation needle of the gynecological tumor radiotherapy locator is provided with a binding groove and a guide head. The operator inserts the uterine cavity tube and the implantation needle into the implantation hole through the guide head. The operator pushes the rubber band bound on the surface of the binding groove into the binding groove, so that the binding groove increases the friction force in the guide head inside the uterine cavity tube and the implantation needle, thereby fixing the uterine cavity tube and the implantation needle in the implantation hole, preventing the uterine cavity tube and the implantation needle from moving radially, and improving the stability of the uterine cavity tube and the implantation needle inserted into the locator.
[0012] 2. The fixed structure of the uterine cavity tube and the insertion needle of the gynecological tumor radiotherapy locator is provided with an end head. The end head is formed by a combination of a spherical surface, an arc surface and a plane surface. The end head can better conform to the anatomical structure of the cervix and the vaginal vault, making it easier to insert the locator body into the patient's vagina and improving the convenience of the operator in inserting the locator body into the vagina.

[0024] 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.
[0025] Embodiment 1:
[0026] See also Figure 1 - Figure 5 A fixing structure of a uterine cavity tube and an implantation needle of a gynecological tumor radiotherapy locator, comprising a locator body 1, a plurality of groups of implantation holes 2 are opened in the middle of the locator body 1, a plurality of groups of guide heads 4 are fixed at one end of the implantation hole 2, a binding groove 5 is opened on the outside of the guide head 4 on the end of the locator body 1, a binding groove 5 is opened on the inside of the guide head 4 on the inner circle of the locator body 1, and a plurality of groups of binding grooves 5 are opened in the middle of the guide head 4, a rubber band 6 is inserted in the middle of the binding groove 5, when the operator inserts the uterine cavity tube and the implantation needle into the implantation hole 2, the operator first wraps the rubber band 6 around and interlacedly binds it on the surface of the guide head 4, and then the operator inserts the uterine cavity tube and the implantation needle into the implantation hole 2 The implant needle is inserted into the guide head 4, and the operator pushes the uterine tube and the implant needle so that the uterine tube and the implant needle pass through the guide head 4 into the implant hole 2, and move the uterine tube and the implant needle to the patient's affected area. Then the operator moves the rubber band 6 wrapped around the surface of the guide head 4, and moves the rubber band 6 into the binding groove 5 opened on the surface of the guide head 4, so that the rubber band 6 increases the friction between the uterine tube and the implant needle and the guide head 4, preventing the uterine tube and the implant needle from moving radially in the implant hole 2, thereby facilitating the operator to fix the uterine tube and the implant needle, and preventing the uterine tube and the implant needle from sliding in the implant hole 2 after a slight collision.
[0027] In other embodiments, a terminal 3 is provided at an end portion of the locator body 1 away from the guide head 4. The terminal 3 can be set to an end surface formed by a combination of a spherical surface, an arc surface and a plane. By setting the terminal 3 to an end surface formed by a combination of a spherical surface, an arc surface and a plane, the operator holds the locator body 1, and the locator body 1 drives the terminal 3 to be inserted into the patient's vagina, so that the end surface formed by the combination of a spherical surface, an arc surface and a plane can better conform to the anatomical structure of the cervix and the vaginal vault, thereby improving the comfort of the operator in inserting the locator body 1 into the patient's vagina.
[0028] In other embodiments, the guide head 4 is tilted at the end of the locator body 1, and an implantation hole 2 is penetrated in the middle of the guide head 4, and the implantation hole 2 and the guide head 4 are arranged in concentric circles. The guide head 4 is not arranged in a concentric circle with the implantation hole 2, so that after the operator inserts the uterine canal and the implantation needle into the implantation hole 2 through the guide head 4, the uterine canal and the implantation needle are tilted relative to the guide head 4, thereby increasing the contact surface between the rubber band 6 and the uterine canal and the implantation needle, increasing the damping, and better preventing the radial displacement of the uterine canal and the implantation needle. At the same time, after the notch of the guide head 4 is removed, the volume of the retained part is large, which increases the strength of the guide head 4, and the pre-tightening force of the rubber band 6 can be further increased to further enhance the damping between the uterine canal and the implantation needle and the rubber band 6, thereby better preventing the radial displacement of the implantation needle.
[0029] Embodiment 2:
[0030] See also Figure 6 - Fig. 9 A fixing structure of a uterine cavity tube and an implantation needle of a gynecological tumor radiotherapy locator, comprising a locator body 1, a plurality of groups of implantation holes 2 are opened in the middle of the locator body 1, a plurality of groups of guide heads 4 are fixed to one end of the implantation holes 2, and a plurality of groups of binding grooves 5 are opened in the middle of the guide heads 4, and a rubber band 6 is inserted in the middle of the binding groove 5. When the operator inserts the uterine cavity tube and the implantation needle into the implantation hole 2, the operator first wraps and interlaces the rubber band 6 around the surface of the guide head 4, and then the operator inserts the uterine cavity tube and the implantation needle into the guide head 4, and the operator pushes the uterine cavity tube and the implantation needle to make the uterine cavity tube The uterine tube and the implantation needle enter the implantation hole 2 through the guide head 4, and the uterine tube and the implantation needle are moved to the patient's affected area. Then the operator moves the rubber band 6 wrapped around the surface of the guide head 4, and moves the rubber band 6 into the binding groove 5 opened on the surface of the guide head 4, so that the rubber band 6 increases the friction between the uterine tube and the implantation needle and the guide head 4, preventing the uterine tube and the implantation needle from moving radially in the implantation hole 2, thereby facilitating the operator to fix the uterine tube and the implantation needle, and preventing the uterine tube and the implantation needle from sliding in the implantation hole 2 after a slight collision.
[0031] In other embodiments, a terminal 3 is provided at the end of the locator body 1 away from the guide head 4. The terminal 3 can be set to an elliptical cylinder to facilitate the matching of the end of the terminal 3 with the patient's vagina so that the terminal 3 can be stably inserted into the patient's vagina.
[0032] In other embodiments, the guide head 4 is vertically arranged on the end of the locator body 1, and an implantation hole 2 is penetrated in the middle of the guide head 4, and the implantation hole 2 is not arranged concentrically with the guide head 4. By not setting the guide head 4 concentrically with the implantation hole 2, the operator inserts the uterine tube and the implantation needle into the implantation hole 2 through the guide head 4. The uterine tube and the implantation needle are inclined to each other with the guide head 4, increasing the contact surface between the rubber band 6 and the uterine tube and the implantation needle, increasing the damping, and better preventing the radial position of the uterine tube and the implantation needle. At the same time, after the guide head 4 removes the notch, the retained part has a large volume, which increases the strength of the guide head 4, and the pre-tightening force of the rubber band 6 can be further increased to further enhance the damping between the uterine tube and the implantation needle and the rubber band 6, thereby better preventing the radial displacement of the implantation needle.
