Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a radiotherapy interpolation positioning and fixation device. Background Technology

[0002] Radiation therapy is one of the main treatment methods for common gynecological tumors. During the treatment of these conditions, a needle implantation is often used as an application channel to deliver the radiation source to the treatment site, thereby ensuring therapeutic efficacy. Especially in the treatment of cervical cancer, the use of needle implantation offers minimally invasive, highly effective, and less painful results, making it a primary technique.

[0003] Current manual implantation techniques are demanding and cannot meet the requirements of speed and precision. Conventional implantation templates are not precise in positioning and fixation, which leads to various human errors during the implantation process, failing to achieve the ideal treatment effect and affecting the later tumor recurrence rate. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide an insertion and fixing device that is simple in structure, easy to operate, and can achieve wide fit and comprehensive force distribution by setting a positioning baffle and fixing device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a radiotherapy interpolation positioning and fixing device, including a column and a positioning baffle, the column passing through the positioning baffle, a fixing handle being provided on the column, the fixing handle being located at the bottom end of the column, and the fixing handle being fixedly connected to the column and the positioning baffle as an integral structure.

[0006] Preferably, the column is a columnar structure with a rounded top and the bottom end of the column passing through a positioning baffle and being fixedly connected to the positioning baffle as an integral structure.

[0007] Preferably, the fixing handle has a cuboid structure, with the end of the fixing handle protruding outward to form a protrusion. The cross-section of the protrusion of the fixing handle is hexagonal, which facilitates the fixing of the clamp.

[0008] Preferably, the positioning baffle is a concave, arc-shaped sheet structure that conforms to the contour of the patient's body surface.

[0009] Preferably, the upper end face of the fixed handle and the bottom end face of the positioning baffle are fixedly connected as an integral structure.

[0010] Preferably, the positioning baffle has an observation hole in the middle, and the cross-section of the observation hole is elliptical, which is used to observe the fit between the positioning baffle and the patient's body surface.

[0011] Preferably, the middle recess of the positioning baffle forms a catheter slot, which starts at the corresponding position of the patient's urethral opening and extends to the edge of the positioning baffle. The catheter slot is used to allow the patient's catheter to pass through without obstruction.

[0012] The beneficial effects of this utility model are:

[0013] 1. The radiotherapy interpolation positioning and fixation device provided by this utility model has a simple structure, is easy to use, and can better fit the patient's application site.

[0014] 2. This utility model has a compact structure, which is convenient for transportation and use. Compared with traditional equipment, it can save costs and has low manufacturing costs.

[0015] 3. The positioning baffle of this utility model fits snugly against the patient's application site, thereby making the positioning more accurate, ensuring good product stability during insertion, and guaranteeing the quality of subsequent treatment. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 4 As shown, the present invention provides a radiotherapy interpolation positioning and fixing device, including a column 1 and a positioning baffle 2. The column 1 passes through the positioning baffle 2, and a fixing handle 11 is provided on the column 1. The fixing handle 11 is located at the bottom end of the column 1, and the fixing handle 11 is fixedly connected to the column 1 and the positioning baffle 2 as an integral structure.

[0023] The column 1 is a columnar structure with a rounded top. The bottom of the column 1 passes through the positioning baffle 2 and is fixedly connected to the positioning baffle 2 as an integral structure.

[0024] The fixing handle 11 has a cuboid structure, and the end of the fixing handle 11 protrudes outward to form a fixing handle protrusion 12. The cross-section of the fixing handle protrusion 12 is hexagonal, which facilitates the fixing of the clamp. In this embodiment, the fixing clamp is an existing mature technology device, and its use or non-use is determined according to actual usage needs.

[0025] In the hexagonal cross-section of the fixed handle protrusion 12, the bottom of the hexagon is fixedly connected to the fixed handle 11 as an integral structure.

[0026] In this embodiment, the cross-sectional diameter and length of column 1 are consistent with the patient's physiological dimensions. During use, the design is tailored to the specific circumstances to ensure better usability. Column 1 is approximately 2cm from the bottom end of positioning baffle 2, approximately 5cm from the other end of positioning baffle 2, and approximately 2cm from each of the two sides of positioning baffle 2. In actual use, the dimensions of positioning baffle 2 are consistent with the patient's physiological data.

[0027] The positioning baffle 2 is a concave, arc-shaped sheet structure that conforms to the contour of the patient's body surface. The upper end face of the fixing handle 11 is fixedly connected to the bottom end face of the positioning baffle 2 as a single unit.

[0028] The projection of the positioning baffle 2 onto the plane containing the bottom surface of the column 1 is trapezoidal in shape, and the end of the fixed handle 11 is connected to the inclined surface at the bottom of the positioning baffle 2.

[0029] The positioning baffle 2 conforms to and fits the contour of the actual part of the body, thus achieving better performance, more accurate positioning, and more even force distribution. The upper end of the fixed handle 11 is fixedly connected to the bottom end of the positioning baffle 2 as a single unit.

[0030] The positioning baffle 2 has an observation hole 24 in the middle. The cross-section of the observation hole 24 is elliptical, which is used to observe the positioning baffle's position and fit with the patient's body surface.

[0031] The positioning baffle 2 has a catheter slot 25 in the middle. The catheter slot 25 starts from the corresponding position of the patient's urethral opening and extends to the edge of the positioning baffle 2. The catheter slot 25 is used to allow the patient's catheter to pass through without obstruction.

[0032] The catheter slot 25 is perpendicular to the long side of the observation hole 24. In practical use, the catheter slot 25 allows for better drainage of fluids, increasing the practicality of this invention. Doctors can observe and record the patient's condition through the observation hole 24.

[0033] Those skilled in the art will recognize that the embodiments described herein are intended to help the reader understand the principles of this invention, and should be understood that the scope of protection of this invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on these technical teachings disclosed in this invention without departing from the essence of this invention, and these modifications and combinations are still within the scope of protection of this invention.
