Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a sentinel lymph node detection probe that can be rapidly sterilized, which is a dedicated device for clinical testing. Background Technology

[0002] Sentinel lymph node biopsy (SLNB) is a surgical procedure used in cancer diagnosis. Its primary 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 state of micrometastasis in the lymphatic system in a timely manner, providing accurate pathological grading and staging, thereby enabling the development of appropriate subsequent clinical treatment strategies.

[0003] In addition, after surgical resection of malignant tumors of internal organs, a thorough examination of the lymph nodes surrounding the removed tumor tissue is usually necessary to assess whether metastasis has occurred. Sentinel lymph node biopsy can also be used for diagnosis. Therefore, numerous SLNB biopsies are required in oncology departments, and the relevant equipment needs to be repeatedly used on multiple different patients. To ensure the safety of the testing, the instruments used must be thoroughly sterilized to prevent infection or transmission.

[0004] The most crucial aspect of the disinfection process is the disinfection of the gamma ray detector probe, as the probe needs to directly contact the patient's body, and in the case of internal testing, it may also come into direct contact with tissues such as lymph nodes. To ensure patient safety and prevent cross-infection, medical devices and testing instrument probes must be disinfected or sterilized during surgical / diagnostic preparation.

[0005] Currently, commonly used methods include disinfectant immersion sterilization, autoclaving, and ultraviolet disinfection. Among these, autoclaving is the most efficient, capable of completely killing various pathogens or residual tissue cells. However, autoclaving can be quite damaging to surgical instruments or diagnostic equipment. If surgical instruments or diagnostic instruments cannot withstand high-pressure steam, other sterilization methods must be used, such as disinfectant immersion sterilization, ethylene oxide sterilization, or hydrogen peroxide immersion sterilization. Different sterilization methods increase the workload of medical staff, and compared to autoclaving, other sterilization methods require longer times to ensure sufficient sterilization effectiveness.

[0006] Because the probes of gamma ray detectors cannot withstand autoclaving, probe sterilization has become a major challenge in surgical / diagnostic preparation, requiring separate pretreatment using non-autoclaving methods. Multiple sterilization methods significantly increase the workload of medical staff, and there is a risk of interference between instruments / equipment treated with different methods. Utility Model Content

[0007] The purpose of this invention is to overcome the problem that existing gamma ray detector probes cannot withstand high-pressure steam sterilization, and to provide a quick-release gamma ray detector probe. It is easy to disassemble and can be quickly sterilized before sentinel lymph node detection. This invention's gamma ray detector probe achieves rapid sterilization, offering greater ease of use compared to traditional sentinel lymph node detection probes.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A probe for a quick-release gamma ray detector, comprising a handle and a probe rod;

[0010] The handle includes a handle body and a control panel. The control panel is located on the side of the handle body and is used to control the probe to perform gamma ray detection and analysis. The front end of the handle is provided with a Remo connector.

[0011] The probe rod includes a Remo connector plug, a fixed long rod, and a probe; the fixed long rod is a long rod with included angles at both ends; the Remo connector plug is located at the tail end of the fixed long rod, and the probe is located at the front end of the fixed long rod;

[0012] The Remo connector socket and the Remo connector plug are matched with each other; the probe rod is connected to the Remo connector plug through a wire set inside the fixed rod, and finally connected to the control panel after the Remo connector plug and the Remo connector socket are matched.

[0013] The probe of this gamma ray detector features a detachable handle and probe rod, allowing for rapid sterilization. For ease of operation, the handle integrates the control panel and handle into a single unit, facilitating operation and analysis by medical personnel. The probe rod connects the handle and the probe at the front end using a fixed, angled rod. During use, rotating the handle allows the probe to be oriented in different directions, achieving more precise detection and diagnosis.

[0014] By using a Remo connector for quick disassembly and assembly of the handle and probe, the handheld part can be easily sterilized without steam pressure, enabling rapid sterilization of the sentinel lymph node detection probe. This ensures that the control circuit is unaffected by steam sterilization and can operate normally for an extended period. During use, the probe connected to the fixed rod can be disassembled and placed separately into the steam pressure sterilization device for rapid and efficient sterilization with other surgical instruments and metal instruments. This eliminates the need for separate sterilization of the handle and probe, achieving rapid sterilization and avoiding the inconvenience of conventional sterilization methods (separate from other surgical instruments). It also effectively avoids the risk of incomplete sterilization caused by conventional methods, fully leveraging the advantages of high-temperature steam sterilization: strong bactericidal efficacy and low cost.

[0015] Furthermore, the two ends of the fixed long rod have an included angle α, where 95°≤α≤170°.

[0016] Preferably, 110°≤α≤170°; preferably, 120°≤α≤170°; preferably, 120°≤α≤165°.

[0017] Furthermore, the handle body has a cavity inside, and a circuit board is disposed inside the cavity. The circuit board is electrically connected to the control panel.

[0018] Furthermore, a battery is installed inside the handle body, and the battery is connected to the control panel or circuit board. The battery function provides convenience and freedom of use.

[0019] Furthermore, the bottom of the handle body is provided with a handle cover, which facilitates disassembly and maintenance of the internal circuit board or replacement of the battery.

[0020] Furthermore, a charging coil holder is also provided at the bottom of the handle body, and the charging coil holder is electrically connected to at least one of the control panel, circuit board, or battery. By providing a charging coil holder at the bottom and connecting it to the control panel circuit, wireless charging is achieved. When the gamma ray detector probe is not in use, it can be placed vertically on the wireless charging base for convenient and rapid charging.

[0021] Furthermore, the control panel is equipped with buttons for turning the gamma ray detector's probe on or off. When not in use, the probe can be turned off to save power and extend battery life.

[0022] Furthermore, the Remo connector is threadedly connected to the front end of the handle body. During installation, the Remo connector is connected to the handle body via the screw thread, and the wiring on the back of the Remo connector is connected to the circuit board.

[0023] Furthermore, the probe rod also includes a probe base, and the probe rod is connected to a fixed long rod through the probe base.

[0024] Furthermore, it also includes a probe cover, which is detachably mounted on the probe. During transportation or storage, the probe cover can be installed to protect the precision probe and prevent abnormal wear from affecting detection accuracy.

[0025] Preferably, the probe cover is an aluminum probe cover.

[0026] Furthermore, the probe rod has an IP65 protection rating. Preferably, the probe rod is a titanium alloy component.

[0027] Furthermore, the handle has an IP65 protection rating.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] 1. The probe of this quick-release gamma ray detector features a detachable handle and probe rod, allowing for rapid sterilization. For ease of operation, the control panel and handle are integrated into one unit, facilitating operation and analysis by medical personnel. The probe rod can be directly removed for high-temperature sterilization, such as at 175℃ for 3 minutes, ensuring thorough and efficient sterilization.

[0030] 2. The quick-release probe of this utility model uses a fixed long rod with an angle to connect the handle and the probe at the front end to form a probe rod. During use, the probe at the front end can be oriented in different directions by rotating the handle, so as to achieve a more accurate detection and diagnosis purpose.

[0031] 3. This utility model's quick-release probe allows for easy separation of the detector and handle, enabling disinfection with disinfectant solution during surgery. A preferred design incorporates IP65 protection for the handle body and probe rod, providing dust and water resistance and ensuring stable and reliable operation.

[0032] 4. The preferred design of the probe of the gamma ray detector of this utility model can adopt a built-in battery design, so that the battery does not need to be replaced.

[0033] 5. The probe and detector of this utility model gamma ray detector have separate and independent structures. When the detector performance degrades or is damaged, only the detector or probe rod needs to be replaced, which effectively reduces maintenance costs. Attached Figure Description

[0048] Example 1

[0049] like Figures 1 to 7 As shown, a quick-release gamma ray detector probe adopts a quick-release probe structure, including a handle and a probe rod, which can be quickly disinfected; the handle includes a handle body 3 and a control panel 4. Figure 3 As shown, the control panel 4 is located on the side of the handle body 3. The control panel 4 is used to control the probe to perform gamma-ray detection and analysis, and the control panel 4 is embedded in the handle. Figure 1As shown, the front end of the handle is provided with a Remo connector socket; the probe rod includes a Remo connector plug, a fixed long rod 9 and a probe 11; the two ends of the fixed long rod 9 are long rods with included angles; the Remo connector plug is located at the tail end of the fixed long rod 9, and the probe 11 is located at the front end of the fixed long rod 9; the Remo connector socket and the Remo connector plug are matched with each other; the probe 11 is connected to the Remo connector plug through a wire located inside the fixed long rod 9, and after the Remo connector plug and the Remo connector socket are matched, it is finally connected to the control panel 4.

[0050] like Figure 1 As shown, the two ends of the fixed long rod 9 have an included angle α, where α = 150°. The probe rod of the detector uses a fixed long rod 9 with an included angle to connect the handle and the probe 11 at the front end. During use, the probe 11 at the front end can be oriented in different directions by rotating the handle, so as to achieve a more accurate detection and diagnosis purpose.

[0051] like Figure 2 As shown, the handle body 3 has a cavity inside, and a circuit board is disposed inside the cavity. The circuit board is electrically connected to the control panel 4. Figure 3 As shown, the control panel 4 is located on the side surface of the handle. At the same time, a battery is installed inside the handle body 3, and the battery is connected to the control panel 4 or the circuit board.

[0052] Furthermore, a handle bottom cover 1 is provided at the bottom of the handle body 3, and the handle bottom cover 1 is as follows: Figure 4 As shown, the bottom cover structure makes it easy to disassemble and maintain the internal circuit board or replace the battery.

[0053] Example 2

[0054] The probe 11 of the quick-release gamma ray detector is the same as that in Example 1, except that a charging coil holder 2 is also provided at the bottom of the handle body 3, as shown in Example 1. Figure 4 As shown, the charging coil is integrated into the bottom cover 1 of the handle, and the charging coil holder 2 is electrically connected to the control panel 4, circuit board, or battery. By setting the charging coil holder 2 at the bottom and connecting it to the control panel 4 circuit, wireless charging is achieved. When the gamma ray detector probe is not in use, it can be placed vertically on the wireless charging base for convenient and rapid charging.

[0055] Furthermore, such as Figure 1 As shown, a button 5 is provided on the control panel 4. Button 5 is used to turn the probe of the gamma ray detector on or off.

[0056] Example 3

[0057] The probe of the quick-release gamma ray detector is the same as that in Example 2, except that the Remo connector 8 is threadedly connected to the front end of the handle body 3. During installation, the Remo connector 8 is connected to the handle body 3 via the screw thread, and the wiring on the back of the Remo connector 8 is connected to the circuit board.

[0058] For Remo connector 8, select HT or MT model Remo connectors, such as... Figure 5 and Figure 6 As shown, the Remo connector plug and Remo connector socket each have a threaded structure, which are connected to the handle or probe rod respectively through the threaded structure. The Remo connector 8 socket is installed on the handle through the connector 7 structure, and can then be used with the Remo connector 8 plug connected to the tail of the fixed long rod 9 to achieve quick assembly and disassembly.

[0059] By using the Remo connector 8 to quickly detach and install the handle and probe rod, the handheld part can be easily treated with non-steam high-pressure sterilization, ensuring the normal operation of the control circuit. At the same time, the probe 11 connected to the fixed rod 9 can be separated from the handle and placed separately in the steam high-pressure sterilization device for rapid and efficient sterilization of other surgical instruments, metal instruments, etc., avoiding the inconvenience of conventional sterilization methods and effectively avoiding the risk of insufficient sterilization caused by conventional sterilization methods.

[0060] Furthermore, the probe rod also includes a probe base 10, which is located at the end of the fixed rod 9 away from the Remo connector plug. The probe 11 is connected to the fixed rod 9 through the probe base 10. This allows for convenient replacement of the probe 11, avoids the complete scrapping of the probe rod, and improves the recyclability of the equipment.

[0061] Example 4

[0062] The probe of the quick-release gamma ray detector is the same as that in Example 3, except that the probe rod also includes a probe aluminum cover 12, which is as follows: Figure 7 As shown, the probe aluminum cover 12 is detachably mounted on the probe 11. During transportation or storage, the probe cover can be installed to protect the precision probe and prevent abnormal wear from affecting detection accuracy.

[0063] Furthermore, both the handle and the probe rod have an IP65 protection rating.

[0064] The probe of this utility model gamma ray detector adopts a detachable handle body 3 and probe rod. For ease of operation, the handle adopts a control panel 4 integrated with the handle into one-piece structure, which makes it convenient for medical personnel to use the detector for detection and analysis.

[0065] Example 5

[0066] The probe 11 of the quick-release gamma ray detector is the same as in Example 1, except that the Remo connector 8 enables quick-release of the handle and probe rod. The probe rod includes the probe 11, a fixed long rod 9, and a plug. The plug of the Remo connector 8 is located at the end of the fixed long rod. The plug has a central hole, inside which a spring is arranged laterally, with its two ends abutting against steel balls. At least one side hole is provided on the side of the central hole, and a steel ball is placed in the side hole. The radius of the side hole is smaller than the radius of the steel ball. Under the elastic action of the spring, the steel ball is engaged in the side hole of the metal rod sidewall and partially protrudes from the side hole.

[0067] The handle has a groove whose size matches the end of the fixed rod, allowing the rod to be inserted into the groove. The side wall of the groove has an annular positioning groove. When the end of the fixed rod is inserted into the groove, the side hole on the side wall of the rod's tail corresponds to the annular positioning groove, and the steel ball, under the elastic force of the spring, extends out of the side hole and partially engages with the annular positioning groove.

[0068] Pressing firmly on the fixing rod will quickly insert it into the groove of the handle. Once the fixing rod is fully inserted, the spring pushes the steel ball out of the side hole and into the annular positioning groove, forming a locking engagement. To remove the fixing rod, simply pull the fixing rod and the handle in opposite directions.

[0069] The probe rod and handle achieve a quick-release structure through the above-described design.

[0070] Furthermore, the Remo connector has an automatic locking structure, making it less likely to fall off once installed and connected.

[0071] Furthermore, the quick-release structure is also encased in a plastic or other insulating shell to protect the internal components.

[0072] The Remo connector at the end of the probe rod has a metal terminal in the middle, which is used to mate with the metal terminal in the groove of the handle to achieve electrical connection.

[0073] Example 6

[0074] The sentinel lymph node detection probe, which is the same as that used in Example 1, is fast-sterilizable. The only difference is that the fixed rod 9 is made up of rods with angles α at both ends. The rods with angles α of 95°, 110°, 120°, 135°, 140° and 150° were tested. Twenty medical staff were invited to try the operation feel of the probes with different angles and to score the operation feel, ease of use and probe pointing accuracy of the rods with different angles.

[0075] Table 1: Probe Usage Effectiveness Rating

[0076]

[0077] After multiple rounds of comparison and testing, medical staff reported that when the included angle α was small, the probe driven by the fixed rod 9 had poor direct pointing accuracy to the test site, making it difficult to align with the test position. While the lateral pointing accuracy was better, the large deflection angle actually increased the operational difficulty. When the probe needed to be aligned in a straight line, the 170° included angle of the fixed rod made operation easier, but its operability decreased during sentinel lymph node detection when pointing laterally or to the side wall of the surgical incision. Ideally, the fixed rod should have a certain degree of curvature, with an included angle α of moderate size, allowing for alignment with the straight test site while also being easily adjustable to the side of the surgical incision. An included angle α within the range of 120° to 170° provided good feel, ease of use, and pointing accuracy.

[0078] In addition, medical staff also reported that the probe needs to be inserted deep into the surgical site for operation. The length L1 of the part in front of the curved position of the fixed rod should not be too long, preferably controlled within the range of 30.5-100mm. When operating the probe for testing, it is easy to align with the area to be tested and avoid interference between the probe and other parts.

[0079] The length L1 of the fixed long rod should be 30.5-65mm. This is suitable for surgical incisions that are small, where the probe can easily enter the opening. At the same time, the probe can point to various test sites during rotation without causing excessive interference with human tissue.

[0080] Ideally, the included angle α between the two ends of the fixed rod should be controlled within the range of 120° to 170°, and the length L1 of the front section of the fixed rod should be set to 30.5-65mm. This will ensure the best operability of the probe and enable the most accurate detection of gamma signals in various parts.
