Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an adjustable-angle implantation template for brachytherapy of cervical cancer. Background Technology

[0002] Three-dimensional interstitial brachytherapy involves inserting a hollow needle into a tumor, through which a radiation source reaches the tumor at close range, killing tumor cells and thus treating the tumor. The core of this technique lies in the location and distribution of the radiation source. After entering the tumor through the needle channel, the radiation source releases a predetermined amount of short-range radiation, maximizing the damage to the tumor tissue while minimizing damage to surrounding healthy tissue.

[0003] Cervical cancer is one of the most common malignant tumors in gynecology. Brachytherapy is an important guarantee for the cure of cervical cancer. Interstitial brachytherapy has improved the cure rate of locally advanced cervical cancer.

[0004] However, existing implantation radiotherapy techniques are quite difficult, the repeatability of manual implantation is poor, and the needle insertion channel is fixed, making it impossible to perform needle insertion in lesion areas that are located in remote areas or requiring the use of templates with corresponding angles, resulting in poor flexibility. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a radiotherapy insertion template with an adjustable insertion needle angle to ensure accurate radiotherapy position and high flexibility.

[0006] To achieve this objective, the present invention adopts the following technical solution: This utility model provides an adjustable angle cervical cancer brachytherapy implantation template, including an implantation plate with mounting holes. An implantation column is installed in the mounting holes. An installation plate is provided at one end of the implantation column. The installation plate abuts against the side of the implantation plate away from the implantation column. The installation plate has several sets of first implantation channels. An angle adjuster is provided inside the first implantation channel for adjusting the needle insertion angle.

[0007] A preferred embodiment of this invention is that the angle adjuster includes a spherical body disposed inside the first insertion channel, the spherical body being rolled along with the first insertion channel, and a needle insertion channel being fixed inside the spherical body for inserting the insertion needle.

[0008] A preferred embodiment of this invention is that a silicone sleeve is fixed to the inner wall of the first insertion channel, and the silicone sleeve is fitted onto the outer wall of the spherical body and slidably connected to the spherical body.

[0009] The preferred technical solution of this utility model is that the insertion plate is provided with a number of guide holes around the corresponding mounting holes, and the mounting plate is provided with guide rods corresponding to the guide holes, and the guide rods are adapted to the guide holes for installation.

[0010] A preferred embodiment of this invention is that a plurality of second insertion channels are distributed around the perimeter of the insertion plate, and the second insertion channels are arranged around the perimeter of the mounting plate.

[0011] A preferred embodiment of this invention is that the insertion post has a through hole, and one end of the angle adjuster extends into the through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides stable support for the implantation column through the cooperation of a guide rod and a guide hole, ensuring stable insertion of subsequent implantation needles. During use, the implantation column is slowly inserted into the predetermined position inside the patient's vagina. Based on CT data and the anatomical location of the cervical cancer, different angle adjusters in the first implantation channel are selected for needle insertion. When encountering lesions in more remote locations, the insertion channel drives the spherical body to adjust the angle. The use of a silicone sleeve stabilizes the position of the insertion channel, ensuring accurate insertion of subsequent implantation needles. This allows the implantation needles to be aligned with the anatomical location of the cervical cancer. Subsequently, a radiation source is connected for brachytherapy. The operation is simple, highly repeatable, and flexible, allowing for needle insertion at different angles and locations of lesions. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] An adjustable-angle brachytherapy implantation template for cervical cancer includes an implantation plate 1 with mounting holes. An implantation column 2 is installed in the mounting holes. An installation plate 3 is provided at one end of the implantation column 2. The installation plate 3 abuts against the side of the implantation plate 1 away from the implantation column 2. The installation plate 3 has several sets of first implantation channels 31. An angle adjuster 4 is provided inside the first implantation channel 31 for adjusting the needle insertion angle. A through hole 21 is passed through the implantation column 2. One end of the angle adjuster 4 extends into the through hole 21. Several sets of second implantation channels 11 are distributed around the perimeter of the implantation plate 1, and the second implantation channels 11 surround the perimeter of the installation plate 3.

[0016] Before use, the implantation column 2 is installed in the mounting hole of the implantation plate 1, so that the mounting plate 3 abuts against the implantation plate 1 to stabilize the position of the implantation column 2 and provide a guarantee for the subsequent insertion of the implantation needle 5. The size of the implantation column 2 can be selected according to the location of the lesion area. During use, the arc-shaped end faces on both sides of the implantation plate 1 are placed between the patient's thighs, and the implantation column 2 is slowly inserted into the predetermined position inside the patient's vagina. Based on CT data and the anatomical location of the local cervical cancer, the angle adjuster 4 in the first implantation channel 31 is selected for needle insertion. When encountering a lesion area that is relatively remote, the angle adjuster 4 is used to adjust the needle insertion so that the needle insertion 5 can be aligned with the anatomical location of the local cervical cancer. Then, the radiation source is connected for brachytherapy. The operation is simple, has higher repeatability, and can be inserted into lesion areas at different angles and positions, which is more flexible and can ensure accurate radiotherapy position and improve radiotherapy effect.

[0017] As a possible implementation of this solution, preferably, the angle adjuster 4 includes a spherical body 41 disposed inside the first insertion channel 31. The spherical body 41 is rotatably disposed with the first insertion channel 31. A needle inlet channel 42 is fixed inside the spherical body 41 for inserting the insertion needle 5. A silicone sleeve 6 is fixed to the inner wall of the first insertion channel 31. The silicone sleeve 6 is sleeved on the outer wall of the spherical body 41 and slidably connected to the spherical body 41.

[0018] Based on the collected CT data, the location of the lesion is confirmed. The insertion angle of the implantation needle 5 is adjusted by adjusting the needle insertion channel 42. Rotating the needle insertion channel 42 causes the spherical body 41 to move along the inside of the silicone sleeve 6 to adjust the angle. Since the silicone sleeve 6 has a certain elasticity, when the angle of the needle insertion channel 42 is adjusted, it can hold the spherical body 41 tightly under the action of the silicone sleeve 6, thereby stabilizing the position of the needle insertion channel 42, so as to facilitate the accurate insertion of the implantation needle 5, provide an accurate radiotherapy position for subsequent treatment, and ensure the radiotherapy effect.

[0019] As a possible implementation of this solution, preferably, the insertion plate 1 is provided with a plurality of guide holes 12 around the mounting hole, and the mounting plate 3 is provided with guide rods 32 corresponding to the guide holes 12. The guide rods 32 are adapted to the guide holes 12 and installed. The mounting plate 3 is fixedly installed with the insertion post 2. During the process of installing the insertion post 2 in the mounting hole, the guide rods 32 are installed corresponding to the guide holes 12, so that the position of the insertion post 2 is provided with stable support under the cooperation of the guide rods 32 and the guide holes 12, ensuring the accuracy of the subsequent insertion of the insertion needle 5.
