Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a gynecological tumor sampler. Background Art

[0002] In the field of gynecological medicine, early detection and diagnosis of tumors are crucial for the treatment and recovery of patients. Traditional tumor sampling methods mainly rely on the doctor's experience and feel, and manually operate sampling instruments (such as biopsy forceps or curettes) to enter the patient's body for sampling. However, this method has many shortcomings and limitations.

[0003] First, manual operation makes it difficult to accurately control the angle and depth of the sampling instrument. Since gynecological tumors may be located at different positions and depths and have different shapes, manual operation often makes it difficult to accurately position the sampling instrument on the tumor tissue, which may lead to inaccurate sampling positions and affect the accuracy of subsequent diagnostic results. Secondly, manual operation takes a long time, increasing the patient's pain and surgical risks. Traditional sampling methods require doctors to constantly adjust and try during the operation to find the best sampling position, which not only prolongs the operation time, but also increases the patient's pain and the risk during the operation. In addition, the structure of traditional sampling instruments is relatively simple and lacks the necessary monitoring and feedback mechanism. During the sampling process, doctors cannot understand the position, angle, depth and other information of the sampling instrument in real time, which further increases the uncertainty and risk of the operation.

[0004] In recent years, with the continuous advancement of medical technology and the increasing demand for the accuracy of gynecological tumor diagnosis, more and more gynecological tumor samplers have been developed to try to solve the above problems. However, most of these samplers still have problems such as complex operation, low sampling accuracy, and insufficient safety. Especially when facing tumors of different locations and shapes, traditional samplers are often difficult to respond flexibly, resulting in poor sampling results and unable to meet clinical needs.

[0005] Therefore, there is an urgent need for a gynecological tumor sampler that can flexibly adjust the sampling angle and depth, is easy to operate, and has high safety, so as to improve the accuracy and efficiency of gynecological tumor diagnosis. Summary of the invention

[0006] To solve the above problems, the present invention provides a gynecological tumor sampler, which combines mechanical design with intelligent monitoring technology, not only allowing medical staff to easily adjust the angle and depth of the sampling needle to adapt to tumors of different locations and shapes, but also greatly improving the accuracy of sampling, significantly enhancing the safety and efficiency of the surgical process.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a gynecological tumor sampler comprises a hose, a sampling needle assembly for sampling is installed at one end of the hose, a power assembly for generating power during sampling is installed at the other end of the hose, the sampling needle assembly comprises a shell, a fixing plate is rotatably matched with the inner side wall of the shell, a sampling needle is eccentrically connected to the fixing plate, a mounting plate is detachably provided at one end of the shell, a circular groove is provided on the mounting plate, a movable plate is rotatably matched at the circular groove, a circular hole matching the sampling needle is provided on the movable plate, the sampling needle is inserted into the circular hole, a plurality of limiting grooves matching the fixing plate are provided on the inner side wall of the shell, the shell is detachably connected to the hose at one end away from the sampling needle, and the inside of the shell is connected to the hose;

[0008] The power assembly includes a piston plate, which is rotatably matched with the inner wall of the hose, a piston rod is fixedly connected to one side of the piston plate, a push rod is fixedly connected to the side of the piston plate away from the piston rod, the end of the piston rod away from the piston plate extends to the outside of the hose and is installed with a handle assembly, a connecting rod is rotatably matched with the inner wall of the shell, the connecting rod extends to the inside of the hose, the fixed plate, the piston plate and the outer wall of the connecting rod are all fixedly connected with a gear ring, the fixed plate is meshed with the connecting rod, and the piston plate is meshed with the connecting rod;

[0009] A monitoring component for monitoring the entry distance of the hose is installed on a mounting plate at one end of the housing away from the hose. The monitoring component signal is connected to a controller, and the controller issues a reminder based on the distance data monitored in real time by the monitoring component.

[0010] The technical principle of the above scheme is as follows: the sampling needle assembly eccentrically installs the sampling needle through the fixed plate in the shell, and the fixed plate rotates with the inner wall of the shell to allow the sampling needle to adjust its angle within a certain range. The movable plate on the mounting plate cooperates with the sampling needle through the circular hole to ensure that the sampling needle remains stable when rotating. The limit groove on the inner wall of the shell is used to fix the fixed plate, thereby controlling the length of the sampling needle extending out of the shell. The toothed ring on the piston plate engages with the connecting rod, and the connecting rod engages with the fixed plate at the same time to form a linkage mechanism. When the piston rod is pushed by the handle assembly, the piston plate moves forward, and at the same time drives the connecting rod and the fixed plate to rotate, so as to achieve the angle adjustment and extension action of the sampling needle. The monitoring component is installed on the mounting plate at one end of the shell away from the hose, and is used to monitor the distance of the hose entering the body in real time. The monitoring component transmits the distance data to the controller, and the controller issues a reminder when the preset depth is reached according to the preset sampling depth data, guiding the medical staff to adjust the angle of the sampling needle and start sampling.

[0011] The above scheme has the following beneficial effects:

[0012] 1. In this solution, by adjusting the angle and extension length of the sampling needle, the sampler of the present invention can flexibly respond to tumors of different positions and shapes, significantly improving the accuracy and success rate of sampling. Compared with traditional devices, it is no longer limited to fixed sampling angles and depths, but can be fine-tuned according to the specific conditions of the tumor, thereby more effectively obtaining tumor tissue samples. Medical staff can adjust the angle of the sampling needle and perform sampling operations through the handle assembly, without the need for complex operating steps, reducing the difficulty of operation and the workload of medical staff.

[0013] 2. In this solution, the real-time monitoring function of the monitoring component ensures that the depth of the hose entering the body is always within a safe range, effectively avoiding the risk of injury to the patient due to excessive insertion or improper angle. This is particularly prominent compared to traditional devices, because traditional devices often lack real-time depth monitoring and feedback mechanisms or rely on rough estimates based on the experience of medical staff, increasing uncertainty during the operation. At the same time, the design of the limit slot also limits the maximum extension length of the sampling needle, providing double protection for the safety of the patient.

[0014] 3. This solution, through the integrated power assembly and the flexible sampling needle adjustment mechanism, can quickly complete the sampling operation, reducing the operation time and the patient's pain. Compared with traditional devices, this high efficiency is particularly important in a busy medical environment, and helps to improve the efficiency and quality of overall medical services. The sampler design of the present invention adopts a detachable connection method, which is convenient for medical staff to thoroughly clean and disinfect each component after surgery, reducing the risk of cross infection. In addition, this design also simplifies maintenance work and extends the service life of the equipment.

[0015] Furthermore, the monitoring component includes an ultrasonic sensor and an image sensor. The ultrasonic sensor is used to monitor in real time the depth of the hose entering the body and the distance information of the surrounding tissues. The image sensor is used to capture a real-time image of the sampling area to provide the doctor with real-time visual feedback of the sampling area.

[0016] Beneficial effects: By integrating ultrasonic sensors and image sensors, the monitoring component can monitor the depth of the hose entering the body and the distance information of the surrounding tissues in real time, and capture real-time images of the sampling area. This dual monitoring mechanism provides doctors with more detailed and accurate information, allowing them to locate tumor tissue more accurately, thereby improving the accuracy of sampling. Compared with traditional devices, the present invention significantly reduces the risk of sampling failure or accidental injury to surrounding tissues due to inaccurate positioning. The ultrasonic sensor can monitor the distance between the hose and the surrounding tissues in real time. Once the distance is lower than the preset safety threshold, the system will immediately issue an alarm to remind medical staff to adjust the operation path or stop insertion, thereby effectively avoiding damage to surrounding tissues. At the same time, the real-time image feedback provided by the image sensor enables doctors to intuitively observe the situation in the sampling area and promptly discover and correct possible operational risks. This dual safety guarantee mechanism greatly improves the safety of operations and reduces the incidence of medical accidents.

[0017] Furthermore, both ends of the shell are provided with external threads, and both ends of the shell are threadably matched with a cover body through the external threads.

[0018] Beneficial effects: The design of the cover body with external threads at both ends of the shell enables medical staff to quickly and tightly close the internal space of the sampler after sampling. This tight sealing method effectively prevents contamination or leakage of samples during transportation and handling, ensuring the integrity and safety of the samples. The threaded matching design between the shell and the cover body not only ensures the closure of the sample, but also enhances the overall structural strength of the equipment. This design enables the sampler to maintain good sealing performance after multiple uses, extending the service life of the equipment. In addition, the threaded matching also has good vibration and impact resistance, which can protect the internal samples from the influence of the external environment to a certain extent.

[0019] Furthermore, the handle assembly includes a guard plate and a handle. The guard plate is fixedly connected to the outer wall of the hose at one end away from the shell. The handle is fixedly connected to the piston rod. Anti-slip grooves are provided on the guard plate and the handle.

[0020] Beneficial effects: The guard plate in the handle assembly is fixedly connected to the outer wall of the end of the hose away from the shell, providing a stable gripping point for medical staff. Combined with the anti-slip grooves set on the handle, medical staff can hold the handle more stably and reduce operational errors caused by hand sliding. This design significantly improves the stability during operation, making the sampling process smoother and more accurate. The anti-slip design not only improves the stability of the grip, but also enhances the comfort of the medical staff during operation. The anti-slip groove can increase the friction between the hand and the handle, reduce hand fatigue, and enable medical staff to maintain a good feel and operating efficiency during long-term operation.

[0021] Furthermore, the sampling needle has a hollow structure, and a plurality of sampling holes are provided at one end of the sampling needle near the needle tip. A scraper rod is provided inside the sampling needle, and a barbed blade is fixedly connected to one end of the scraper rod. The outer edge of the barbed blade slides with the inner wall of the sampling needle. Scrapers are provided on the scraper rod corresponding to the sampling holes, and the end of the scraper rod away from the scraper passes through the sampling needle, the piston rod and the handle in sequence.

[0022] Beneficial effects: The sampling needle is designed as a hollow structure and is equipped with a scraper rod and a barbed blade, which makes the sampling process more efficient and accurate. The scraper can easily scrape the tumor tissue in the sampling hole, while the barbed blade can further cut and collect the tissue. This dual-action mechanism ensures the integrity and accuracy of the sampling, and improves the efficiency and quality of sampling. The fine design of the scraper and the barbed blade enables them to minimize damage to the surrounding normal tissue while cutting the tumor tissue. This design not only protects the health of the patient, but also reduces the risk of surgical complications.

[0023] Furthermore, it also includes an early warning component, which is connected to the controller signal. The early warning module is used to issue an early warning based on the judgment result of the controller. The early warning component includes an indicator light and a buzzer. The indicator light and the buzzer are both embedded in the handle. The indicator light flashes and emits light of different colors to indicate different early warning levels. The buzzer emits an alarm. When the distance data monitored in real time by the monitoring component exceeds the threshold, the controller sends an instruction to the early warning component, and the indicator light and the buzzer send corresponding early warning information.

[0024] Beneficial effects: The introduction of the early warning component significantly improves the operational safety of the sampler. By monitoring the distance data in real time and comparing it with the preset threshold, the controller can promptly detect potential operational risks and send early warning information to medical staff through indicator lights and buzzers. This design enables medical staff to respond at the first time to avoid possible medical accidents and ensure patient safety. The indicator lights and buzzers are embedded in the handle, so that medical staff can intuitively see and hear the early warning information during the operation without distracting their attention to check other devices or displays. This design improves the convenience of operation, allowing medical staff to focus more on the sampling process and improve operational efficiency and accuracy. The indicator lights can flash and emit different colors of light to indicate different warning levels. This design provides a multi-level early warning mechanism. Different levels of early warning information can help medical staff better understand the current risk level and take corresponding countermeasures. This flexible early warning mechanism makes the sampling process more controllable and reliable.

[0025] Furthermore, the hose and the piston rod are both made of medical plastics.

[0026] Beneficial effects: The hose and piston rod are made of medical plastic, which has good toughness and bending properties, allowing the sampler to better adapt to the complex environment in gynecological surgery. Medical staff can flexibly adjust the position and angle of the hose and piston rod according to the needs of the operation to ensure the smooth progress of the sampling process. This design improves the flexibility and convenience of operation and reduces the difficulty of surgery. The hose and piston rod made of medical plastic are relatively soft in texture and will not cause excessive pressure or discomfort to the patient's body. During the sampling process, this softness helps to reduce damage to surrounding tissues, reduce surgical risks, and improve patient comfort.

[0027] Furthermore, a sealing ring is provided between the housing of the sampling needle assembly and the mounting plate, and the sealing ring is made of elastic material.

[0028] Beneficial effects: A sealing ring is provided between the housing and the mounting plate of the sampling needle assembly, which can effectively prevent liquid or gas from leaking from the connection. Since the sealing ring is made of elastic material, it can form a good sealing effect between the housing and the mounting plate, ensuring that the sample during the sampling process will not be contaminated by the outside world, and at the same time protecting the internal mechanical structure from the influence of the external environment. The presence of the sealing ring not only improves the sealing performance of the sampling needle assembly, but also enhances the overall stability of the device. By tightly connecting the housing and the mounting plate, the sealing ring can reduce the risk of loosening or damage caused by vibration or impact, ensuring that the sampler can maintain a stable working state during the operation.

[0029] Furthermore, the outer wall of the hose is provided with scale markings, which are used by the doctor to visually judge the insertion depth of the hose during the operation.

[0030] Beneficial effects: The scale markings on the outer wall of the hose provide doctors with an intuitive reference, allowing them to accurately judge the depth of hose insertion during the operation. This design helps doctors to accurately control the sampling position when taking samples, avoiding excessive or shallow insertion and unnecessary damage to surrounding tissues, thereby ensuring the accuracy and integrity of sampling. The presence of scale markings means that doctors do not need to frequently use other measuring tools to confirm the depth of hose insertion during surgery, thereby saving surgical time and improving surgical efficiency. Doctors can focus more on the surgery itself and reduce distractions caused by measuring and confirming the depth.

[0031] Furthermore, a handle is fixedly connected to one end of the scraper rod away from the barbed blade, and the scraper is triangular in shape with a blade on the edge.

[0032] Beneficial effects: The scraper is designed to be triangular in shape, with a blade on its edge. This shape allows the scraper to have a larger contact area when scraping tumor tissue. The triangular scraper can better fit the shape of the tumor tissue when rotating, so as to obtain tumor tissue samples more accurately. This design reduces the risk of incomplete sampling or taking normal tissue due to improper scraper shape, and improves the accuracy of sampling. The fixed connection of the handle allows medical staff to more conveniently control the movement trajectory and strength of the scraper when operating the scraper rod. This design reduces the difficulty of operation, allowing medical staff to complete the sampling process more easily, and reducing the surgical risks caused by improper operation.

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figures 1 to 5 As shown: a gynecological tumor sampler, including a hose 1, a sampling needle assembly for sampling is installed at one end of the hose 1, and a power assembly for generating power when sampling is installed at the other end of the hose 1. The sampling needle assembly includes a shell 2, and the inner wall of the shell 2 is rotatably matched with a fixing plate 3, and the fixing plate 3 is eccentrically connected with a sampling needle 4. A mounting plate 201 is detachably provided at one end of the shell 2, and a circular groove is provided on the mounting plate 201, and a movable plate 202 is rotatably matched at the circular groove, and a circular hole matching the sampling needle 4 is provided on the movable plate 202, and the sampling needle 4 is inserted into the circular hole. The inner wall of the shell 2 is provided with some The limit groove 203 matches the fixed plate 3, the end of the housing 2 away from the sampling needle 4 is detachably connected to the hose 1, and the interior of the housing 2 is connected to the hose 1; the sampling needle 4 is a hollow structure, and the end of the sampling needle 4 near the needle tip is provided with a plurality of sampling holes 401, and the sampling needle 4 is provided with a scraper rod 402 inside, and one end of the scraper rod 402 is fixedly connected with a barb-shaped blade, and the outer edge of the barb-shaped blade is slidably matched with the inner wall of the sampling needle 4, and the scraper rod 402 and the sampling hole 401 are provided with a scraper 403, and the end of the scraper rod 402 away from the scraper 403 sequentially penetrates the sampling needle 4, the piston rod 6 and the handle 8. The end of the scraper rod 402 away from the barb-shaped blade is fixedly connected with a grip 404, and the scraper 403 is triangular, and the edge has a blade.

[0046] The power assembly includes a piston plate 5, which is rotatably matched with the inner wall of the hose 1. A piston rod 6 is fixedly connected to one side of the piston plate 5, and a push rod 501 is fixedly connected to the side of the piston plate 5 away from the piston rod 6. The piston rod 6 extends to the outside of the hose 1 away from the piston plate 5 and is installed with a handle 8 assembly. A connecting rod 7 is rotatably matched with the inner wall of the shell 2, and the connecting rod 7 extends to the inside of the hose 1. The outer walls of the fixed plate 3, the piston plate 5 and the connecting rod 7 are all fixedly connected with gear rings. The fixed plate 3 is meshed with the connecting rod 7, and the piston plate 5 is meshed with the connecting rod 7; the handle 8 assembly includes a guard plate 9 and a handle 8. The guard plate 9 is fixedly connected to the outer wall of the hose 1 away from the shell 2, the handle 8 is fixedly connected to the piston rod 6, and anti-slip patterns are provided on the guard plate 9 and the handle 8.

[0047] A monitoring component for monitoring the entry distance of the hose 1 is installed on the mounting plate 201 at one end of the housing 2 away from the hose 1. The monitoring component signal is connected to the controller, and the controller makes a reminder based on the distance data monitored in real time by the monitoring component. The monitoring component includes an ultrasonic sensor and an image sensor. The ultrasonic sensor is used to monitor the depth of the hose 1 entering the body and the distance information of the surrounding tissues in real time. The image sensor is used to capture the real-time image of the sampling area to provide the doctor with real-time visual feedback of the sampling area.

[0048] The hose 1 and the piston rod 6 are both made of medical plastics, and in this embodiment, medical grade polypropylene (PP) or polyethylene (PE) is used, which have good toughness and bending properties. A sealing ring is provided between the housing 2 of the sampling needle assembly and the mounting plate 201, and the sealing ring is made of elastic material.

[0049] The specific implementation process is as follows: Based on the patient's medical test data (such as B-ultrasound, CT, etc.), determine the approximate location and depth of the tumor. These test data provide doctors with detailed information about the location, size and morphology of the tumor, which helps to plan the sampling path and depth. According to the specific situation of the patient, the controller sets the distance threshold. This threshold is based on the location and depth of the tumor, as well as the safe sampling depth that the doctor hopes to achieve. By presetting the distance threshold, the controller can monitor and remind the doctor in real time during the insertion of the hose 1 to ensure that the sampling operation is carried out within a safe range.

[0050] Prepare the patient for surgery, such as disinfection and anesthesia. This is an important step to ensure a safe and sterile surgical procedure, which can reduce surgical risks and patient discomfort. Connect the housing 2 of the sampling needle assembly to the hose 1 through threads to ensure that the connection is tight and sealed. This step is a key part of the sampler assembly, and a loose connection may lead to sample contamination or sampling failure.

[0051] The medical staff slowly inserts the sampling needle assembly and the hose 1 into the patient's body. During the insertion process, the sampling needle 4 is located inside the housing 2 to prevent the sampling needle 4 from damaging surrounding tissues during the insertion process. At the same time, the medical staff monitors the insertion depth of the hose 1 and the sampling needle assembly in real time through the ultrasonic sensor in the monitoring assembly to ensure that the hose 1 and the sampling needle 4 are inserted according to the predetermined path and depth.

[0052] Medical staff slowly and carefully insert the sampling needle assembly and hose 1 into the patient's body. During this process, the sampling needle 4 is cleverly designed inside the housing 2. This layout is intended to minimize any damage that the sampling needle 4 may cause to surrounding tissues during insertion. Medical staff must operate gently and precisely to ensure the safety and comfort of the patient. As the hose 1 and the sampling needle assembly gradually go deeper, medical staff rely on the ultrasonic sensor in the monitoring component for real-time monitoring. The ultrasonic sensor not only accurately measures the depth of the hose 1 entering the body, but also carefully captures the distance information of the surrounding tissues. These data are crucial to ensure that the hose 1 and the sampling needle 4 can be inserted along the predetermined path and depth.

[0053] For example, suppose that medical staff are sampling uterine tumors for patients. During the insertion process, the real-time feedback data from the ultrasonic sensor shows that the hose 1 is entering the uterus at a safe depth and angle. Its working principle is: like a medical ultrasonic ranging sensor, its working principle is to calculate the distance by emitting ultrasonic pulses and receiving the reflected signal. During the insertion of the hose 1, the sensor can continuously emit ultrasonic pulses and measure the time from the emission to the reflection of the pulse, so as to calculate the distance from the tip of the hose 1 to the surrounding tissues or organs. At the same time, the image sensor also captures the real-time image of the sampling area, providing clear visual feedback for the doctor. Medical staff can clearly see the tumor position that the sampling needle 4 is about to reach, and understand the specific situation of the sampling area, including tissue morphology, vascular distribution, etc. If the ultrasonic sensor detects that the front end of the sampler is about to contact a sensitive or dangerous tissue area, the controller will immediately respond to alert the medical staff to ensure that they can adjust the insertion angle or depth in time to avoid any potential risks.

[0054] When the hose 1 and the sampling needle assembly reach the preset sampling depth, the doctor sends a command through the controller to arrive at the command. At this time, the medical staff can start to adjust the angle of the sampling needle 4 to adapt to the specific position and shape of the tumor. By rotating the piston rod 6, the piston rod 6 drives the piston plate 5 to rotate, and the piston plate 5 causes the connecting rod 7 engaged therewith to rotate, and the connecting rod 7 drives the fixed plate 3 to rotate. When the fixed plate 3 rotates, the eccentrically connected sampling needle 4 rotates accordingly, and finally the sampling needle 4 is rotated to a suitable angle (this angle change is relative to the shell 2, and finally the sampling needle 4 is rotated to a suitable angle to accurately align with the tumor tissue). After adjusting the angle of the sampling needle 4, the medical staff pushes the piston rod 6 through the handle 8 to move the piston plate 5 forward, and the push rod 501 on the piston plate 5 pushes the fixed plate 3 and the sampling needle 4 out. The limit groove 203 on the inner wall of the shell 2 allows the fixed plate 3 to be fixed at different positions, so that the sampling needle 4 extends different lengths and penetrates the tumor tissue.

[0055] After reaching the sampling position, the scraper 403 is driven to rotate by rotating the handle 404 on the outside of the scraper rod 402. When the scraper 403 rotates, the tumor tissue in the sampling hole 401 is scraped off, and then the scraper rod 402 is pulled outward, and the barb-shaped blade is driven to move. When the barb-shaped blade moves, the tumor tissue in the sampling hole 401 is cut off and falls into the barb-shaped blade groove, and the tumor tissue is taken out as the barb-shaped blade moves. The design of the scraper 403 and the barb-shaped blade can effectively cut the tumor tissue and collect it in the sampling hole 401, while avoiding injury to normal tissue. Since the scraper 403 is in the shape of a triangular prism, the area it scrapes is larger, and the sampling process can be completed faster. The triangular prism shape allows the scraper 403 to better fit the shape of the tumor tissue when rotating, thereby more accurately obtaining tumor tissue samples. While pulling the scraper rod 402, the piston rod 6 is pulled through the handle 8, and the piston rod 6 drives the piston plate 5 to generate negative pressure inside the housing 2, which helps to suck the tumor tissue in the barbed blade groove inside the sampling needle 4 into the housing 2 and temporarily store it there.

[0056] After the sampling is completed, the medical staff slowly pulls the sampling needle assembly and the hose 1 out of the patient's body. During the extraction process, the extraction depth and path need to be monitored in real time by the monitoring component to ensure safety. After extraction, the sampler is immediately sent to the laboratory for subsequent processing and analysis. The laboratory staff will open the sampler housing 2, take out the collected tumor tissue sample, and perform necessary processing and preservation.

[0057] Embodiment 2:

[0058] The difference from the first embodiment is that both ends of the outer shell 2 are provided with external threads 204 , and both ends of the outer shell 2 are threadedly matched with a cover body through the external threads 204 .

[0059] The specific implementation process is as follows: When the sampling is completed, the medical staff will pull the sampling needle assembly and the hose 1 out of the patient's body, and then the medical staff will immediately remove the shell 2 from the hose 1, and then screw the cover bodies on the two ends of the shell 2. Since both ends of the shell 2 are provided with external threads 204, these covers can be tightly fixed on the shell 2 through threaded fit, thereby effectively closing the internal space of the sampler to prevent sample contamination or leakage. Next, the medical staff will quickly send the sampler (including the closed shell 2 and the sample inside) to the laboratory for subsequent processing and analysis. In the laboratory, the professional will open the cover of the shell 2, take out the collected tumor tissue samples, and perform necessary processing and preservation for subsequent pathological analysis or other research.

[0060] Embodiment 3:

[0061] The difference from Example 2 is that it also includes an early warning component, which is connected to the controller signal. The early warning module is used to issue an early warning based on the judgment result of the controller. The early warning component includes an indicator light and a buzzer. The indicator light and the buzzer are both embedded in the handle 8. The indicator light flashes and emits light of different colors to indicate different early warning levels. The buzzer sounds an alarm. When the distance data monitored in real time by the monitoring component exceeds the threshold, the controller sends an instruction to the early warning component, and the indicator light and the buzzer send corresponding early warning information.

[0062] In this embodiment, the indicator light is designed to emit red, yellow, and green lights, which correspond to different warning levels. Red indicates a serious warning, yellow indicates a medium warning, and green indicates a normal or safe state. The buzzer is used to emit alarm sounds of different frequencies and volumes to assist in reminding medical staff.

[0063] The specific implementation process is as follows: During the sampling process, the monitoring component will continuously monitor the depth of the hose 1 entering the body and the distance information of the surrounding tissues in real time, and transmit these data to the controller. The controller will determine in real time whether the current operation is within the safe range based on the preset distance threshold (for example, the closest distance between the hose 1 and the surrounding tissues must not be less than 5mm) and the real-time monitored data.

[0064] For example, when the distance between the hose 1 and the surrounding tissue is detected to be less than 5 mm, the controller will immediately determine that it is beyond the safety range and send a command to the warning component. At this time, the indicator light on the handle 8 will begin to flash red, indicating a serious warning; at the same time, the buzzer will also emit a high-frequency alarm to alert medical staff. After hearing the alarm and seeing the red indicator light flashing, the medical staff will immediately stop the sampling operation and check the current situation. If it is determined that the operation path is improper or the hose 1 has entered too deep, the medical staff will adjust the operation path or gently pull out the hose 1 to ensure the safety of the patient.

[0065] Embodiment 4:

[0066] The difference from Example 3 is that the outer side wall of the hose 1 is provided with scale marks, which are used for the doctor to visually judge the insertion depth of the hose 1 during the operation.

[0067] The specific implementation process is as follows: During the insertion process, the medical staff pays close attention to the scale marks on the outer wall of the hose 1. These scale marks provide an intuitive basis for judging the insertion depth of the hose 1. By reading the values ​​on the scale marks, the medical staff can accurately understand the specific depth of the hose 1 that has been inserted into the body, thereby ensuring that the operation is performed within a safe range. At the same time, combined with the real-time monitoring function of the monitoring component, the medical staff can further ensure the safety of the operation.

[0068] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
