Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and specifically relates to a device for collecting specimens excised under a digestive endoscope. Background Art

[0002] In the medical field, especially in digestive endoscopy surgeries, the excision of diseased tissues and the collection of specimens are important and complex tasks. Traditional devices for collecting specimens excised under a digestive endoscope have multiple problems during operation, which can be mainly summarized as the following aspects:

[0003] 1. Traditional devices rely on manual operation by medical staff for specimen collection and excision. The operation time is long, and the accuracy of excision is difficult to guarantee. This not only increases the labor intensity of medical staff, but also may affect the surgical efficiency and the treatment effect of patients; 2. During the collection process, the stability of the specimen is difficult to guarantee, and it is easy to be damaged or lost. This may not only lead to specimen contamination or confusion, but also may affect subsequent pathological examinations and diagnoses; 3. Traditional devices have a risk of misexcision during the excision process, which may cause unnecessary damage to surrounding normal tissues and increase the surgical risk; 4. Medical staff need to manually operate multiple steps for specimen collection and excision, and the operation is cumbersome and difficult. This not only increases the complexity of the surgical operation, but also may affect the safety and accuracy of the surgery; 5. For larger-shaped specimens, traditional devices may need to be excised multiple times to achieve complete excision, with complex operation and low efficiency. This limitation makes it difficult for traditional devices to adapt to changes in different surgical requirements; 6. Traditional devices usually cannot record key information during the surgical process, such as the negative pressure magnitude, excision time, etc. This makes it difficult to trace and analyze the surgical results and cannot provide sufficient data support for medical staff.

[0004] With the continuous progress and development of medical technology, devices for collecting specimens excised under a digestive endoscope are also constantly undergoing technological innovation and improvement. Such devices will pay more attention to intelligent, automated and user-friendly designs to improve surgical efficiency and quality, reduce the work intensity of medical staff, and provide better treatment effects and experiences for patients. At the same time, with the continuous emergence of new materials, new processes and new technologies, the performance and functions of such devices will also be further improved and expanded.

[0005] In view of the above problems, the medical field urgently needs a new device for collecting specimens excised under a digestive endoscope to improve surgical efficiency, ensure specimen stability, reduce the excision risk, simplify the operation process, improve adaptability and facilitate data recording. Therefore, the present invention proposes a device for collecting specimens excised under a digestive endoscope to solve the above problems. Summary of the Invention

[0006] The present invention provides a device for collecting specimens removed under a digestive endoscope. Through the integrated design of a negative pressure component and a collection component, it solves the problems of long operation time, low resection accuracy, poor specimen stability, cumbersome operation, and low resection efficiency for specimens with larger shapes in traditional collection devices.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A device for collecting specimens removed under a digestive endoscope includes a negative pressure component, a collection component, and a controller. The negative pressure component includes a negative pressure tube and a negative pressure generator. One end of the negative pressure tube is communicated with the output end of the negative pressure generator, and the collection component is installed at the other end of the negative pressure tube;

[0008] The collection component includes a housing. An installation chamber is provided inside the housing. One end of the housing is communicated with the negative pressure tube. Inside the installation chamber at the other end of the housing, a plurality of vertical plates are fixedly connected along the circumference. Sliding grooves are provided at the tops of the vertical plates, and vertical rods are slidably fitted in the sliding grooves. Cutting components are installed on the vertical rods;

[0009] The cutting component includes a baffle. An electric cutting knife is installed on the outer side wall of the baffle. Channels are respectively opened inside the vertical plates. The two ends of the channels are respectively communicated with the sliding groove and the inside of the housing. Sliding blocks are slidably fitted in the channels. A flexible connecting piece is fixedly connected between the top of the sliding block and the bottom of the vertical rod;

[0010] Both the negative pressure generator and the electric cutting knife are signal-connected to the controller. The controller is used to control the power and on / off of the negative pressure generator. When a specimen of the required size is adsorbed inside the housing, the controller starts the electric cutting knife to cut the specimen.

[0011] After adopting the above solution, the following beneficial effects are achieved:

[0012] 1. Usually, traditional collection devices rely on manual operation by medical staff for specimen collection and resection, with long operation time and difficult to guarantee the accuracy of resection.

[0013] The device of the present invention realizes the efficient collection of specimens removed under a digestive endoscope through the combination of the negative pressure component and the collection component. The negative pressure generated by the negative pressure generator enables the housing to quickly and accurately adsorb the target specimen, reducing the operation time and improving the surgical efficiency. At the same time, the design of the cutting component enables the specimen to be quickly and accurately resected after being adsorbed. The electric cutting knife cuts the specimen along a preset path under the precise control of the controller, ensuring the accuracy and efficiency of the resection.

[0014] 2. During the collection process of traditional devices, it is difficult to guarantee the stability of the specimen, and it is easy to be damaged or lost. At the same time, there is a risk of accidental resection during manual resection.

[0015] During the collection process, due to the tight combination of the negative pressure component and the collection component, as well as the precise design of the vertical plate and the chute, the stability and safety of the specimen during collection are ensured, avoiding damage or loss of the specimen during collection. During the resection process, it can effectively prevent the electrotome from accidentally cutting or other unnecessary injuries, further improving the safety of the operation.

[0016] 3. For traditional devices, medical staff need to manually operate multiple steps for specimen collection and resection, which is cumbersome and difficult.

[0017] The device of the present invention precisely controls the negative pressure generator and the electrotome through the controller. Medical staff only need to make simple settings to achieve automatic collection and resection of specimens. This design greatly simplifies the surgical operation process and reduces the operation difficulty of medical staff.

[0018] 4. For larger-shaped specimens with traditional devices, it may be necessary to perform multiple resections to achieve complete resection, which is complex and inefficient.

[0019] The design of the resection component of the device of the present invention enables the device to avoid the situation of multiple resections according to different surgical requirements to achieve the resection of larger-shaped specimens. This feature makes the device have good flexibility and adaptability.

[0020] 5. Traditional devices usually cannot record key information during the operation, such as the negative pressure magnitude, resection time, etc.

[0021] The controller of the device of the present invention can record key information during the operation, such as the negative pressure magnitude, resection time, etc. These data provide data support for the traceability and analysis of the surgical results, helping medical staff better understand the surgical situation and formulate subsequent treatment plans.

[0022] In summary, the device of the present invention is superior to traditional endoscopic resection specimen collection devices in terms of efficiency, stability, safety, ease of operation, flexibility and adaptability, as well as data recording and analysis, providing a more convenient, efficient and safe surgical tool for medical staff.

[0023] Furthermore, a plurality of pressure sensors are installed on the inner side wall of the outer shell. The pressure sensors are longitudinally arranged along the circumference of the outer shell on the inner side wall. The pressure sensors are all signal-connected to the controller. The controller calculates whether the volume of the specimen adsorbed by the collection component is equal to the required volume according to the real-time monitoring data of the pressure sensors and the preset position information.

[0024] Beneficial effects: The pressure sensors are longitudinally arranged along the circumference of the outer shell on the inner side wall of the outer shell, capable of real-time monitoring of the pressure changes at different positions inside the outer shell. Based on these real-time monitoring data, the controller can accurately determine whether the volume of the specimen adsorbed by the collection component is equal to the required volume. This ability of real-time monitoring and precise control ensures the accuracy and reliability of specimen collection during the surgical procedure. Meanwhile, the ability to precisely control the specimen volume also reduces the time wasted due to multiple operations, thereby improving the efficiency of the entire surgical procedure. Different surgeries may require collecting specimens of different volumes. By adjusting the preset position information and specimen volume parameters, the device of the present invention can flexibly adapt to different surgical requirements. This flexibility gives the device a broader application prospect and higher practical value.

[0025] Furthermore, an image sensor is installed on the inner side wall of the outer shell. The image sensor is signal-connected to the controller, and the controller checks and verifies the specimen adsorbed by the collection component according to the real-time monitoring data of the image sensor.

[0026] Beneficial effects: The image sensor can capture and transmit the image data of the specimen inside the outer shell to the controller in real time. Based on these real-time data, the controller can conduct an immediate verification check on the specimen adsorbed by the collection component to ensure the accuracy, integrity, and compliance of the specimen. Compared with traditional visual inspection, the image sensor provides a faster and more accurate verification method. Medical staff can view the image of the specimen through the controller without opening the outer shell, thus greatly reducing the inspection time and workload. Manual inspection often has subjectivity and errors. The objective and accurate image data provided by the image sensor can reduce human errors and improve the reliability of specimen verification.

[0027] Furthermore, a limiting block is fixedly connected to the end of the channel far away from the sliding groove. A first electromagnet is embedded in the limiting block, and a second electromagnet is embedded in the side of the slider far away from the flexible connecting member. Both the first electromagnet and the second electromagnet are signal-connected to the controller, and the controller controls the activation and magnetism of the first electromagnet and the second electromagnet.

[0028] Beneficial effects: Through the electromagnetic force, the first electromagnet and the second electromagnet can precisely control the position of the slider within the channel, thereby achieving precise control of the resection assembly (including the baffle and the electrocautery knife). This control method ensures that the resection assembly can accurately reach the designated position when needed for precise resection operations. The control method of the electromagnet avoids the instability and errors that may be brought by mechanical transmission, improving the stability and reliability of the entire device. At the same time, through precise electromagnetic force control, it can effectively prevent the electrocautery knife from accidentally cutting or other unnecessary injuries, further enhancing the safety of the operation. By controlling the activation and magnetism of the electromagnet through the controller, medical staff do not need to manually operate multiple components. They only need to make simple settings through the operation interface to achieve precise control of the resection assembly. This design greatly simplifies the surgical operation process and reduces the operation difficulty of medical staff.

[0029] Furthermore, a protection assembly is installed on the side of the resection assembly away from the chute. The protection assembly is used to cover the surface of the electrocautery knife when the electrocautery knife is not working to protect the electrocautery knife and prevent accidental injury. The protection assembly includes a guard plate. A number of notches matching the vertical rods are provided on the guard plate. A limit groove is provided at one end of the housing away from the negative pressure tube. The guard plate is rotationally matched with the limit groove.

[0030] Beneficial effects: When the electrocautery knife is not working, the guard plate of the protection assembly can cover the surface of the electrocautery knife, effectively preventing damage or contamination that the electrocautery knife may suffer when exposed to the external environment, ensuring the durability and reliability of the electrocautery knife. The guard plate covering the surface of the electrocautery knife effectively isolates the electrocautery knife from direct contact with medical staff or other surgical instruments, greatly reducing the risk of accidental injury caused by misoperation and improving the safety of the surgical process. Since the protection assembly can effectively protect the electrocautery knife from damage and contamination, the service life of the electrocautery knife can be extended, reducing the additional costs and time brought by replacing the electrocautery knife.

[0031] Furthermore, a flow regulating valve is installed on the negative pressure tube. The flow regulating valve is signal-connected to the controller. The controller can control the flow regulating valve to adjust the negative pressure flow in the negative pressure tube according to requirements.

[0032] Beneficial effects: The introduction of the flow regulating valve enables precise control of the negative pressure flow, thereby ensuring the stability and accuracy of the negative pressure flow during the operation. This is crucial for surgeries that require precise control of the specimen collection speed. By adjusting the negative pressure flow in real time, it can quickly adapt to different surgical needs, accelerating or slowing down the specimen collection speed. This helps medical staff complete surgical operations more efficiently, shortening the operation time. Appropriate negative pressure flow helps protect tissues and cells from damage. By precisely adjusting the negative pressure flow through the controller, unnecessary damage to tissues or cells caused by excessive or insufficient negative pressure can be avoided.

[0033] Furthermore, a strainer is installed at the connection between the outer shell and the negative pressure tube.

[0034] Beneficial effects: The strainer can effectively filter out large tissue fragments, blood clots or other impurities entering the negative pressure tube, thereby preventing the negative pressure tube from losing its function due to blockage. This ensures the stable operation of the negative pressure system and avoids surgical interruption or delay caused by blockage. The strainer can block large substances from entering the negative pressure system, thereby reducing the risk of contamination. This helps to keep the surgical environment clean and reduces the risk of infection caused by contamination.

[0035] Furthermore, the outer shell is detachably connected to the negative pressure tube. Outer spiral threads are provided on the outer side walls of both ends of the outer shell, and cover bodies are threadedly engaged with the outer spiral threads.

[0036] Beneficial effects: Since the outer shell is detachably connected to the negative pressure tube, medical staff can conveniently remove the outer shell from the negative pressure tube for thorough cleaning and disinfection. This helps to reduce the risk of cross-infection during the operation and improves the reusability of the device. Similarly, the threaded engagement design of the cover body also makes it easy to disassemble and install, facilitating the cleaning and maintenance of the interior of the outer shell. The threaded engagement design of the outer spiral threads and the cover body can ensure a tight connection between the outer shell and the cover body, providing good sealing performance. This can prevent contamination or safety problems caused by equipment leakage during specimen transportation.

[0037] Furthermore, an identification area is also provided on the outer shell. The identification area is used to record patient information, surgical time and specimen information.

[0038] Beneficial effects: The information on the identification area can clearly record key information such as the source of each specimen, patient information, surgical time, etc., enabling the specimen to be accurately traced during subsequent inspection, analysis, preservation or transportation. This helps to ensure the accuracy and reliability of the specimen and improve the medical quality. Through the information on the identification area, medical staff can quickly identify and check the specimen, reducing medical errors caused by specimen confusion or mistakes. This helps to ensure patient safety and reduce the risk of medical accidents.

[0039] Furthermore, the controller is also equipped with a display screen and an operation interface. The display screen is used to view the working status of the device in real time, and the operation interface is used to input operation commands and set parameters.

[0040] Beneficial effects: The display screen can display the working status of the device in real time, such as negative pressure flow rate, specimen collection progress, etc., providing immediate feedback information for medical staff. This helps medical staff to promptly understand the operation of the device, and thus make corresponding adjustments and operations. Through the operation interface, medical staff can intuitively input operation commands and set parameters, without cumbersome manual operations or adjustments. This design greatly simplifies the operation process and improves work efficiency. The parameter setting function on the operation interface allows medical staff to precisely adjust the working parameters of the device according to surgical needs, such as negative pressure flow rate, working time, etc. This helps to ensure that the device operates in the best state and reduces the risks caused by improper operation.

[0052] The following is a further detailed description through specific embodiments:

[0053] Embodiment 1 is basically as shown in the attached Figures 1 to 7 figures: A specimen collection device for endoscopic resection of digestive tract includes a negative pressure assembly, a collection assembly, and a controller. The negative pressure assembly includes a negative pressure tube 1 and a negative pressure generator. One end of the negative pressure tube 1 is communicated with the output end of the negative pressure generator, and a flow regulating valve is installed on the negative pressure tube 1. The collection assembly is installed at the other end of the negative pressure tube 1; the collection assembly includes a housing 2, an installation chamber 201 is provided inside the housing 2, one end of the housing 2 is communicated with the negative pressure tube 1, and a plurality of vertical plates 3 are fixedly connected along the circumference inside the installation chamber 201 at the other end of the housing 2. A chute 301 is provided at the top of each vertical plate 3, and a vertical rod 4 is slidably fitted in each chute 301. An excision assembly is installed on each vertical rod 4. The excision assembly includes a baffle 401, an electric cutting knife 402 is installed on the outer side wall of the baffle 401. A protection assembly is installed on the side of the excision assembly away from the chute 301. The protection assembly is used to cover the surface of the electric cutting knife 402 when the electric cutting knife 402 is not working to protect the electric cutting knife 402 and prevent accidental injury. The protection assembly includes a protection plate 7, a plurality of notches 701 matching the vertical rods 4 are provided on the protection plate 7, and a limiting groove is provided at one end of the housing 2 away from the negative pressure tube 1. The protection plate 7 is rotatably fitted with the limiting groove.

[0054] A channel 302 is provided inside each of the vertical plates 3. The two ends of the channel 302 are respectively communicated with the chute 301 and the inside of the housing 2. A slider 5 is slidably fitted in the channel 302. A flexible connector 501 is fixedly connected to the top of the slider 5 and the bottom of the vertical rod 4. A limiting block 303 is fixedly connected to one end of the channel 302 away from the chute 301. A first electromagnet is embedded in the limiting block 303, and a second electromagnet is embedded on the side of the slider 5 away from the flexible connector 501. Both the first electromagnet and the second electromagnet are in signal connection with the controller, and the controller controls the activation and magnetism of the first electromagnet and the second electromagnet.

[0055] A plurality of pressure sensors 6 are installed on the inner side wall of the housing 2. The pressure sensors 6 are longitudinally arranged along the circumference of the housing 2 on the inner side wall of the housing 2. An image sensor is installed on the inner side wall of the housing 2. The negative pressure generator, the flow regulating valve, the electric cutter 402, the pressure sensor 6 and the image sensor are all in signal connection with the controller.

[0056] The controller is also equipped with a display screen and an operation interface. The display screen is used to view the working status of the device in real time, and the operation interface is used to input operation commands and set parameters. The controller controls the power and opening / closing of the negative pressure generator. The controller can control the flow regulating valve to adjust the negative pressure flow in the negative pressure tube 1 according to requirements. The controller calculates whether the volume of the specimen adsorbed by the collection component is equal to the required volume according to the real-time monitoring data of the pressure sensor 6 and the preset position information. When the specimen of the required size is adsorbed in the housing 2, the controller activates the electric cutter 402 to cut the specimen. The controller checks and verifies the specimen adsorbed by the collection component according to the real-time monitoring data of the image sensor.

[0057] The specific implementation process is as follows: Before use, medical staff precisely set the required specimen volume, shape and other relevant parameters through the operation interface, which helps to ensure the pertinence and accuracy of subsequent operations. During use, medical staff gently transport the collection component and the cutting component to the target position under the digestive endoscope through the negative pressure tube 1. After determining that the preset position is reached, the opening of the housing 2 is accurately aligned with the specimen to be cut to ensure that the specimen can be smoothly adsorbed.

[0058] Then, the medical staff starts the negative pressure generator through the controller. The negative pressure generator generates a stable negative pressure through the negative pressure tube 1, so that the housing 2 adsorbs the specimen efficiently. When the specimen is inhaled into the housing 2, the pressure sensor 6 on the inner side wall of the housing 2 monitors in real time and transmits the real-time monitoring data to the controller. The controller calculates the volume of the adsorbed specimen according to the real-time monitoring data of the pressure sensor 6 and the preset position information. When the volume of the adsorbed specimen reaches the required size, the controller adjusts the power of the negative pressure generator to ensure that the adsorbed specimen is no longer adsorbed and at the same time prevent the already adsorbed specimen from falling off.

[0059] Based on the real-time monitoring data from the image sensor, the controller conducts precise verification checks on the adsorbed specimen to confirm whether it meets the requirements. Once the specimen passes the verification, that is, it meets the preset specimen size, shape, or other requirements, the controller will proceed to the next step. The controller will send signals to the first electromagnet and the second electromagnet to adjust their magnetic pole states, changing the originally repulsive magnetism to attractive magnetism, which provides strong support for the subsequent cutting operation.

[0060] Due to the negative pressure in the channel 302, under the combined action of the negative pressure and the electromagnet, the slider 5 rapidly moves along the channel 302, pulling the vertical rod 4 through the flexible connecting piece 501, causing the baffle 401 and the electrocautery knife 402 to move towards the center of the opening of the housing 2. Since the first electromagnet and the second electromagnet attract each other, the pulling force of the flexible connecting piece 501 is increased, making the moving speed and force of the vertical rod 4 faster and greater. The movement of the vertical rod 4 drives the baffle 401 and the electrocautery knife 402 to move towards the center of the opening of the housing 2, gradually exposing the electrocautery knife 402 for operation. As the vertical rod 4 moves, the relative position between the notch 701 on the guard plate 7 and the electrocautery knife 402 changes, ensuring that the electrocautery knife 402 is not obstructed by the guard plate 7 during operation.

[0061] When the electrocautery knives 402 of all cutting components move to the preset working positions, the controller activates the electrocautery knives 402 to start the cutting operation on the specimen. The electrocautery knives 402 precisely cut the specimen according to the preset cutting path. After the cutting is completed, the controller can control the electrocautery knives 402 to stop working.

[0062] After the specimen is cut, the baffle 401 on the cutting component forms a tight cover, covering the opening of the housing 2. Due to the existence of the cover, during the removal process, this design effectively prevents the specimen from falling or contaminating the digestive tract during removal, ensuring the safety and cleanliness of the operation.

[0063] After removing the collection component, the controller will readjust the magnetic pole states of the first electromagnet and the second electromagnet to return from the attractive state to the initial repulsive state. Under the repulsive force of the electromagnet, the slider 5 will return to the initial position along the channel 302. At the same time, through the flexible connecting piece 501, the vertical rod 4 will also move outward (i.e., away from the center) in the sliding groove 301. It can be opened to safely handle and clean the cut specimen.

[0064] Embodiment 2 is different from the above embodiment in that: a strainer is installed at the connection between the housing 2 and the negative pressure tube 1, the housing 2 and the negative pressure tube 1 are detachably connected, external threads 202 are provided on the outer side walls at both ends of the housing 2, and covers are threadedly fitted on the external threads 202. A marking area is also provided on the housing 2, and the marking area is used to record patient information, operation time, and specimen information.

[0065] The specific implementation process is as follows: After the endoscopic surgery is completed, when it is necessary to remove the collection component from the patient's body, medical staff will carefully operate the endoscopic system to slowly remove the collection component together with the specimen. In this process, the sieve plays a key role. Due to the existence of the sieve, the specimens excised inside the outer shell 2 will not fall deeper into the negative pressure tube 1 during the movement, thus ensuring the integrity and safety of the specimens.

[0066] Once the collection component is completely removed, medical staff will first remove the outer shell 2 from the negative pressure tube 1. Then, they will screw the cover body tightly and fix it at both ends of the outer shell 2 through the external spiral threads 202 at both ends of the outer shell 2. This operation ensures the sealing inside the outer shell 2, provides preliminary protection for the excised specimens, and prevents the specimens from being contaminated or damaged during subsequent processing.

[0067] After fixing the cover body, medical staff will record the patient information, operation time, and specimen information in detail on the identification area of the outer shell 2. These information are crucial for subsequent pathological analysis. They can help pathologists understand the source of the specimens, the patient's medical history, and the operation situation, so as to make a more accurate diagnosis. In addition, these information are also of great significance for the follow-up of patients and can help doctors better understand the patient's recovery situation.

[0068] After recording the information, the collection component will be sent to the pathology department for further processing and analysis. Medical staff will ensure the integrity and safety of the specimens throughout the process to obtain accurate pathological results. At the same time, they will also formulate a more appropriate treatment plan for the patient according to the pathological results and the patient's specific situation.

[0069] The above are only the embodiments of the present invention, and common knowledge such as specific structures and / or characteristics known in the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners and other records in the specification can be used to explain the content of the claims.
