Description

Technical Field

[0001] This utility model relates to the field of detection device structure, specifically to a gamma ray detection device for sentinel lymph node detection, belonging to the field of medical detection equipment technology. Background Technology

[0002] Sentinel lymph node biopsy (SLNB) is a surgical procedure used for cancer diagnosis. Its main purpose is to assess whether cancer cells have spread from the primary tumor to the lymphatic system. Sentinel lymph nodes are the first lymph nodes to receive lymph fluid from the tumor area, making them potential sites of metastasis. By examining these lymph nodes for cancer cells, doctors can detect the micrometastasis status of the lymphatic system in a timely manner, providing accurate pathological grading and staging, thereby enabling the development of appropriate subsequent clinical treatment strategies.

[0003] Radioactive isotope tracers are typically injected around or within the tumor the day before or on the day of surgery, and sometimes subcutaneously around the tumor. After injection, the tracer travels through the lymphatic system to the lymph nodes. A gamma ray detector can detect the radioactive signal from outside the body to locate the sentinel lymph node. Radioactive isotope tracers provide highly sensitive lymphatic mapping, helping to accurately identify sentinel lymph nodes, especially when the lymph nodes are deep within tissue or located in fatty areas. The tracer effectively travels from the injection site to the sentinel lymph node, allowing detection even of distant lymph nodes. By measuring the intensity of the radioactive signal using a gamma ray detector, quantitative analysis of the radioactive absorption of the sentinel lymph node (SLN) can be performed, enabling precise localization of the sentinel lymph node.

[0004] Currently, common gamma ray detection devices mainly consist of a handle, a probe, and a probe connected in sequence. However, the distance and direction of the probe from the lymph node cannot be adjusted at any time, which causes some inconvenience to surgery, increases the difficulty of operation, and results in low detection efficiency.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0029] Furthermore, the use of terms such as "first," "second," "third," etc. in terminology is merely for distinguishing identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0030] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0031] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0032] Example 1

[0033] like Figure 1 As shown, a gamma-ray detection device for sentinel lymph node detection includes a handle 1, a probe 2, and a probe 3 connected in sequence; the probe 2 includes a first probe 21 and a second probe 22 connected in sequence; wherein, the first probe 21 is located at the end near the probe 3 and has a gooseneck structure; the second probe 22 has a telescopic structure.

[0034] The entire probe is divided into a telescopic section and a direction-adjustable section. During use, the distance and direction of the probe to the sentinel lymph node can be adjusted at any time according to the actual surgical situation by adjusting the bending angle of the first probe and the length of the second probe. This greatly facilitates the location of lymph nodes, reduces the difficulty of operation, effectively improves detection efficiency, and has a simple structure that is easy to promote and use.

[0035] As those skilled in the art will know, the second probe 22 is a telescopic structure, specifically capable of freely adjusting its length. The length of the entire second probe is changed through relative sliding or telescopic movement between two or more sections. Specifically, it can be a threaded connection, a tenon-and-hook connection, a gear connection, etc. When it is necessary to adjust the length of the telescopic rod, this can be achieved by changing the relative position between the rods. For example, if a threaded connection is used, the threads can be rotated to gradually separate or bring the two rods closer together, thereby changing the length of the entire rod. If a tenon-and-hook connection is used, the tenon between the rods can be removed or inserted, thereby changing the length of the entire rod.

[0036] from Figure 1 As can be seen from the example, the second probe 22 in Embodiment 1 consists of two telescopic rods. Figure 2 The figure shows a cross-sectional view of the threaded connection of the second probe rod 22. By rotating the connection point of the two telescopic rods, the connection position can be loosened or tightened, thereby compressing or stretching the engagement state of the two telescopic rods, achieving the effect of adjusting the length of the second probe rod 22.

[0037] In some specific embodiments, the first probe 21 and the second probe 22 are rotatably connected. Making the first probe 21 and the second probe 22 rotatably connected makes it easier to adjust the direction of the probe towards the sentinel lymph node during subsequent surgical procedures.

[0038] Example 2

[0039] Example 2 provides the same gamma ray detection device as Example 1, except that in Example 2, the second detection rod 22 of the gamma ray detection device consists of three telescopic rods, specifically as follows: Figure 3 and Figure 4 As shown.

[0040] Specifically, the handle 1 is equipped with a control module, which is electrically connected to the probe 3 and is used to receive electrical pulse signals from the probe.

[0041] As those skilled in the art will understand, the probe includes a cylindrical housing, within which are a scintillation crystal, an avalanche diode, a power circuit board, and a connector connected in sequence. Inside the probe, the scintillation crystal maximally shields against gamma rays generated by surrounding matter, receives gamma rays directly in front, and converts these rays into photons. These photons are then converted into photons by the avalanche diode. The power circuit provides operating voltage to the avalanche diode and the connector. The connector is electrically connected to the avalanche diode, allowing the output of the electrical pulse signal converted by the avalanche diode. After the connector is electrically connected to the control module, the control module can receive the electrical pulse signal from the probe.

[0042] The probe rod 2 is a hollow tube, and the connecting wire of the probe 3 passes through the hollow tube and connects to the control module.

[0043] In some specific embodiments, the second probe 22 is connected to the handle 1 via a Remo connector 4, and the connecting wire of the probe 3 is connected to the control module via the Remo connector 4. Specifically, the front end of the handle 1 is provided with a Remo connector socket, and the end of the second probe 22 away from the first probe 21 is provided with a Remo connector plug. The Remo connector socket and the Remo connector plug are compatible. The connecting wire of the probe is connected to the Remo connector plug through a hollow tube, and after the Remo connector plug and the Remo connector socket are matched, it is finally connected to the control module.

[0044] In some specific embodiments, a control panel 11 is provided on the surface of the handle 1. Preferably, the control panel 11 includes a switch structure 111; the control panel 11 includes an indicator light structure 112.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
