Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a tumor sampling device for facilitating tumor separation. Background Art

[0002] In tumor diagnosis and treatment, accurately obtaining tumor samples is a key step in pathological analysis, gene detection, and personalized treatment. Traditional tumor sampling mainly relies on surgical operations. Although this method is accurate, it is invasive, has a long recovery time, and places a large burden on the patient's body. With the progress of medical technology, minimally invasive techniques such as fine needle aspiration (FNA) and core needle biopsy (CNB) have been widely adopted. These techniques collect tissue samples by using needles of different specifications, reducing the trauma and recovery time of patients.

[0003] In the prior art, for example, the patent with the publication number CN118750045B discloses a tumor sampling device for facilitating tumor separation. This patent first inserts a sampling tube into the tumor, and then separates the tumor sample from the tumor through a separation mechanism. However, this patent lacks the avoidance and shielding of surrounding tissues, and may obtain samples of surrounding tissues during sampling, which may lead to low sampling accuracy.

[0004] In summary, how to solve the problem that some sampling devices in the prior art lack the avoidance and shielding of surrounding tissues and may obtain samples of surrounding tissues during sampling, which may lead to low sampling accuracy has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a tumor sampling device for facilitating tumor separation. Summary of the Invention

[0005] To solve the above problems, the present invention provides a tumor sampling device for facilitating tumor separation. By driving a driving component to drive a rotating disk to rotate, an arc-shaped sliding trajectory of a sliding block in a sliding groove is realized, and then the mutual approach or separation of baffles is driven; the interference of surrounding tissues on sampling is reduced, thereby improving the accuracy and success rate of tumor sampling.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A tumor sampling device for facilitating tumor separation includes a sampling tube with an opening at the top, and an expansion component for expanding surrounding tissues is provided on the sampling tube.

[0007] The expansion component includes a rotating disk and a plurality of sliding blocks. A sliding groove for the sliding of the sliding blocks is opened along the circumference of the top of the sampling tube; baffles are fixedly connected to the tops of the sliding blocks, and the rotating disk is rotatably fitted inside the side wall of the sampling tube; an arc-shaped groove is opened along the circumference of the rotating disk, and an interface communicating with the opening is opened on the rotating disk; clamping rods are fixedly connected to the bottoms of the sliding blocks, and the bottom ends of the clamping rods are located in the arc-shaped groove and are slidably fitted with the arc-shaped groove.

[0008] The sampling tube is also provided with a driving assembly for driving the rotating disk to rotate, a cutting assembly for cutting tumor samples, a suction assembly for aspirating blood and a disinfection assembly for conveying disinfectant; the driving assembly is used to drive the cutting assembly, the suction assembly and the disinfection assembly to operate synchronously.

[0009] The technical principles of the above scheme are as follows:

[0010] The rotating disk is driven to rotate by the driving component. Since the rotating disk is provided with an arc groove for sliding of the clamping rod along its circumference, the clamping rod is fixedly connected to the bottom of the sliding block, and the top of the sliding block is fixedly connected with a baffle; therefore, during the rotation of the rotating disk, the clamping rod can slide in the arc groove, thereby driving the sliding block to slide in the sliding groove, so as to achieve the mutual approach or separation of the baffles. When the baffles are separated, the surrounding tissue above the sampling tube can be stretched open, which is conducive to the sampling of the tumor. During the operation of the driving component, the cutting component can be used to cut the tumor sample, the suction component can be used to suck the blood produced after cutting, and the disinfection component can be used to disinfect it, thereby improving the safety of sampling.

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

[0012] 1. The present invention drives the rotating disk to rotate through the driving assembly, and utilizes the sliding cooperation between the arc groove and the clamping rod to realize the linear sliding track of the sliding block in the sliding groove, thereby driving the baffles to move closer or farther from each other. This design is not only easy to operate, but also can open the surrounding tissue above the sampling tube, provide an open operating space for tumor sampling, reduce the interference of surrounding tissue on sampling, and only sample the tumor during cutting, thereby improving the accuracy and success rate of sampling.

[0013] 2. The present invention integrates multiple steps such as sampling, cutting, suction and disinfection into one, and realizes the coordinated work of various components through the linkage control of the driving components. This integrated design not only simplifies the operation process, but also further improves the sampling efficiency, reduces the complexity of frequent instrument replacement or frequent operation, thereby shortening the operation time, reducing the patient's pain and surgical risks.

[0014] 3. In the sampling process, the present invention can cut tumor samples more quickly and accurately through the combined action of the expansion component and the cutting component, thereby reducing excessive damage and contamination of the sample. At the same time, the suction component can timely suck the blood produced after cutting, keep the surgical field clear, and reduce the stimulation and contamination of the surrounding tissues by the blood. In addition, the use of the disinfection component further ensures the sterility of the surgical area, effectively reduces the risk of infection, and improves the safety of sampling.

[0015] Furthermore, the driving assembly includes a controller, a first gear, an inner gear ring and a rotating member, the controller is used to control the output shaft of the rotating member to rotate; the rotating member is embedded and installed in the side wall of the sampling tube, and the output shaft of the rotating member is coaxially fixedly connected to the first gear; the first gear and the inner gear ring are meshed with each other, and the inner gear ring is fixedly connected to the bottom of the rotating disk.

[0016] Beneficial effect: The first gear is driven to rotate by the rotating member. Since the first gear is meshed with the inner gear ring, and the inner gear ring is fixedly connected to the bottom of the rotating disk, the inner gear ring can be driven to rotate by the rotation of the first gear, and the inner gear ring drives the rotating disk to rotate synchronously, thereby realizing power transmission.

[0017] Furthermore, the cutting assembly includes a plurality of second gears, a plurality of first cutting knives and a second cutting knives, the second gears are all meshed with the inner gear ring; the first cutting knives and the second cutting knives are arranged alternately, and the first cutting knives and the second cutting knives are fixedly connected to the second gears adjacent thereto.

[0018] Beneficial effect: Since the second gear is meshed with the inner gear ring, the first cutter and the second cutter are staggered and fixedly connected to the second gear, the second gear can be driven to rotate by the inner gear ring, and when the second gear rotates, the first cutter and the second cutter can be moved closer to each other or farther away from each other. When they are closer to each other, the tumor sample can be cut, thereby achieving the separation of the tumor sample.

[0019] Furthermore, the suction assembly includes a storage cylinder, a plurality of suction chambers and a piston plate, and the piston plates are slidably matched with the inner side walls of the suction chambers adjacent thereto; the tops of the suction chambers are connected with suction tubes and extraction tubes, and the connections between the suction tubes and the extraction tubes and the suction chambers are connected with a first one-way valve; one end of the suction tube away from the suction chamber is connected to the side of the baffle plate close to the opening, and one end of the extraction tube away from the suction chamber is connected to the storage cylinder.

[0020] The sampling tube is provided with a transmission component for driving the piston plate to reciprocate.

[0021] Beneficial effects: The piston plate is driven to reciprocate by the transmission component, and suction and thrust are generated when the piston plate reciprocates. When the piston plate generates suction, the blood generated after tumor cutting can be sucked, and when thrust is generated, the blood is transported to the storage cylinder for storage; and by utilizing the design of multiple suction cavities, blood from multiple areas can be sucked at one time, thereby increasing the neatness of sampling.

[0022] Furthermore, the disinfection component includes a liquid storage cylinder, a plurality of input tubes and output tubes, and the input tubes and the output tubes are connected to the bottom of the suction cavity; the end of the input tube away from the suction cavity is connected to the liquid storage cylinder, and the end of the output tube away from the suction cavity is connected to the opening; the connection between the input tube and the output tube and the suction cavity is connected to a second one-way valve.

[0023] Beneficial effects: Since the input pipe and the output pipe are connected to the bottom of the suction cavity, when the piston plate generates suction and thrust, the disinfectant liquid inside the liquid storage cylinder can be transported to the cut area, thereby disinfecting the cut area. This process is carried out synchronously during the process of sucking blood, and the disinfectant liquid transported to the cutting part can also be sucked out, further increasing the cleanliness of the cut area.

[0024] Furthermore, the transmission assembly includes a plurality of lead screws and nut seats. The lead screws are coaxially and fixedly connected to the adjacent second gears; the lead screws all penetrate through the suction cavity and are in threaded cooperation with the nut seats, and the nut seats are all fixedly connected to the adjacent piston plates; sealing rings are fixedly connected to the connections between the lead screws and the suction cavity.

[0025] Beneficial effects: Since the lead screws are coaxially and fixedly connected to the second gears, the nut seats are in threaded cooperation with the lead screws, and the nut seats are all fixedly connected to the piston plates, when the second gear rotates, it can drive the lead screws to rotate synchronously. When the lead screws rotate, they can drive the piston plates to reciprocate through the nut seats. During this process, the suction cavity can provide a limit for the piston plates to keep them moving along a stable linear motion trajectory.

[0026] Furthermore, a camera is fixedly connected to the top of the sampling tube, and the controller is used to receive and store the image information sent by the camera.

[0027] Beneficial effects: Through the design of the camera, real-time image feedback can be provided, enabling doctors to visually see the specific situation of the sampling site during the operation; it helps to more accurately locate the tumor position and improve the accuracy and effectiveness of sampling.

[0028] Furthermore, a lighting lamp is also fixedly connected to the top of the sampling tube, and the controller is used to control the on and off of the lighting lamp.

[0029] Beneficial effects: Through the design of the lighting lamp, sufficient light can be provided during the operation to ensure that the sampling area is clearly visible, which is beneficial to improving the operation accuracy.

[0030] Furthermore, a suction pump is also connected to the end of the sampling tube far away from the opening, and the controller is used to control the on and off of the suction pump; the input end of the suction pump is connected to the opening.

[0031] Beneficial effects: Through the design of the suction pump, the tumor sample can be sucked out after being cut, thereby improving the sampling efficiency of the sample.

[0032] Furthermore, a refrigerator is also provided at the end of the sampling tube far away from the opening, and the controller is used to control the on and off of the refrigerator; the output end of the refrigerator is connected to the opening.

[0044] The following is a further detailed description through specific embodiments:

[0045] Embodiment 1:

[0046] As shown in the Figures 1 - 8 accompanying drawings: A tumor sampling device for facilitating tumor separation includes a sampling tube 1 with an opening at the top, and a dilation assembly for expanding the surrounding tissue is provided on the sampling tube 1.

[0047] The expansion component includes a rotating disk 2 and a plurality of sliding blocks 3. A sliding groove for the sliding of the sliding blocks 3 is formed along the circumference of the top of the sampling tube 1; a baffle 4 is integrally formed on the top of each sliding block 3, and the rotating disk 2 is rotatably fitted inside the side wall of the sampling tube 1; an arc-shaped groove is formed along the circumference of the rotating disk 2, an interface communicating with the opening is formed on the rotating disk 2, a clamping rod 5 is fixedly bonded to the bottom of each sliding block 3, and the bottom ends of the clamping rods 5 are located inside the arc-shaped groove and are slidably fitted with the arc-shaped groove.

[0048] The sampling tube 1 is further provided with a driving component for driving the rotation of the rotating disk 2, a cutting component for cutting tumor samples, a suction component for sucking blood, and a disinfection component for transporting disinfectant; the driving component is used to drive the cutting component, the suction component, and the disinfection component to operate synchronously.

[0049] Combined with Figure 3 As shown in the figure, the driving component includes a controller, a first gear 6, an internal gear ring 7, and a rotating member. In this embodiment, the rotating member is a motor 8; the controller is used to control the rotation of the output shaft of the motor 8; the motor 8 is embedded and installed inside the side wall of the sampling tube 1, and the output shaft of the motor 8 is coaxially and fixedly clamped with the first gear 6; the first gear 6 meshes with the internal gear ring 7, and the internal gear ring 7 is fixedly connected to the bottom of the rotating disk 2 by screws.

[0050] Combined with Figure 5 As shown in the figure, the cutting component includes a plurality of second gears 9, a plurality of first cutting knives 10, and a second cutting knife 11. The second gears 9 all mesh with the internal gear ring 7; the first cutting knives 10 and the second cutting knives 11 are arranged alternately, and the first cutting knives 10 and the second cutting knives 11 are both fixedly clamped with the adjacent second gears 9.

[0051] Combined with Figure 8 As shown in the figure, the suction component includes a storage cylinder 12, a plurality of suction cavities 13, and a piston plate 14. The piston plates 14 are all slidably fitted with the inner side walls of the adjacent suction cavities 13; the tops of the suction cavities 13 are all communicated with a suction pipe and an extraction pipe, and first one-way valves are communicated at the joints of the suction pipe and the extraction pipe with the suction cavities 13; the other ends of the suction pipes are all communicated to the side of the baffle 4 close to the opening, and the other ends of the extraction pipes are all communicated with the storage cylinder 12. In this embodiment, the storage cylinder 12 is used to store blood.

[0052] The sampling tube 1 is provided with a transmission component for driving the piston plate 14 to reciprocate. The transmission component includes a plurality of lead screws 16 and nut seats 17. The lead screws 16 are all coaxially and fixedly clamped with the adjacent second gears 9; the lead screws 16 all penetrate through the suction cavities 13 and are in threaded cooperation with the nut seats 17, and the nut seats 17 are all fixedly bonded to the adjacent piston plates 14; sealing rings are fixedly bonded at the joints of the lead screws 16 and the suction cavities 13. The design of the sealing rings can reduce the occurrence of liquid overflow.

[0053] The disinfection assembly includes a liquid storage cylinder 15, a plurality of input tubes and output tubes, and the input tubes and the output tubes are connected to the bottom of the suction chamber 13; the other ends of the input tubes are connected to the liquid storage cylinder 15, and in this embodiment, the liquid storage cylinder 15 is used to store disinfectant; the other ends of the output tubes are connected to the opening; the connection points of the input tubes and the output tubes with the suction chamber 13 are connected to a second one-way valve.

[0054] The specific implementation process is as follows:

[0055] First, before taking tumor samples, the baffle 4 is adjusted to a state of being close to each other; the first gear 6 is driven to rotate by the motor 8. Since the first gear 6 is meshed with the inner gear ring 7, and the inner gear ring 7 is screwed and fixed to the bottom of the rotating disk 2, the inner gear ring 7 can be driven to rotate by the rotation of the first gear 6, and the inner gear ring 7 drives the rotating disk 2 to rotate synchronously, thereby realizing power transmission.

[0056] Since the rotating disk 2 is provided with an arc groove along its circumference for the sliding of the clamping rod 5, the clamping rod 5 is fixedly bonded to the bottom of the sliding block 3, and the top of the sliding block 3 is integrally formed with a baffle 4; therefore, during the rotation of the rotating disk 2, the clamping rod 5 can slide in the arc groove, thereby driving the sliding block 3 to slide in the sliding groove, and the sliding of the sliding block 3 can realize the mutual approach or separation of the baffle 4, and when the baffle 4 is separated, the surrounding tissue above the sampling tube 1 can be stretched, which is conducive to the sampling of the tumor. Figure 6 For example, when the rotating disk 2 rotates counterclockwise, the arc groove rotates counterclockwise, so that the sliding block 3 drives the baffles 4 to move closer to each other; otherwise, the baffles 4 can move away from each other.

[0057] Since the second gear 9 is meshed with the inner gear ring 7, the first cutter 10 and the second cutter 11 are staggered and fixedly connected with the second gear 9, so the second gear 9 can be driven to rotate by the inner gear ring 7, and when the second gear 9 rotates, the first cutter 10 and the second cutter 11 can be moved closer to each other or farther away from each other. When the first cutter 10 and the second cutter 11 are moved closer to each other, the tumor sample can be cut, thereby achieving the separation of the tumor sample. Figure 5 For example, when the second gear 9 rotates clockwise, it can drive the first cutter 10 and the second cutter 11 to move away from each other; otherwise, it can make the first cutter 10 and the second cutter 11 move closer to each other. In this embodiment, when the baffles 4 move away from each other, the first cutter 10 and the second cutter 11 move closer to each other.

[0058] Since the screw rods 16 are coaxially fixedly connected to the second gear 9, the screw rods 16 are threadedly fitted with nut seats 17, and the nut seats 17 are fixedly bonded to the piston plate 14, the screw rods 16 can be driven to rotate synchronously when the second gear 9 rotates. The rotation of the screw rods 16 can drive the piston plate 14 to slide vertically back and forth through the nut seats 17. In this process, the suction chamber 13 can provide a limit for the piston plate 14, so that it maintains a stable linear motion trajectory.

[0059] When the piston plate 14 slides vertically back and forth, suction and thrust are generated according to its upward and downward movement trajectories. When the piston plate 14 generates suction, the blood generated after tumor cutting can be sucked, and when the thrust is generated, the blood is transported to the storage cylinder 12 for storage; and by utilizing the design of multiple suction cavities 13, blood from multiple areas can be sucked at one time, thereby increasing the neatness of tumor sampling.

[0060] Since the input tube and the output tube are connected to the bottom of the suction cavity 13, the disinfectant in the liquid storage cylinder 15 can be transported to the cut area when the piston plate 14 generates suction and thrust, thereby disinfecting the cut area. This process is carried out synchronously during the process of sucking blood, and the disinfectant delivered to the cut area can also be sucked out, further increasing the cleanliness of the cut area. In this embodiment, the baffles 4 are close to each other before tumor sampling, and the piston plate 14 is located at the top of the suction cavity 13, and the external disinfectant is stored in the suction cavity 13. When tumor sampling is performed, the piston plate 14 moves downward to transport the disinfectant to the cut area. At the same time, the blood in the cut area can also be sucked into the suction cavity 13 above the piston plate 14.

[0061] In the prior art, when sampling a tumor, it is usually necessary to carry out the sampling in multiple steps, which is relatively cumbersome. This embodiment integrates multiple steps such as sampling, cutting, suction and disinfection into one, and realizes the coordinated work of various components through the linkage control of the inner gear ring 7 and the first gear 6. This integrated design not only simplifies the operation process, but also further improves the sampling efficiency, reduces the complexity of frequent instrument replacement or frequent operation, and is conducive to shortening the operation time, reducing the pain of patients and the risk of surgery.

[0062] The rotating disk 2 is driven to rotate by the inner gear ring 7 and the first gear 6, and the sliding cooperation between the arc groove and the clamping rod 5 is used to realize the linear sliding track of the sliding block 3 in the sliding groove, thereby driving the baffles 4 to move closer or farther away from each other. This design is not only easy to operate, but also can open the surrounding tissue above the sampling tube 1, provide an open operating space for tumor sampling, reduce the interference of surrounding tissues on sampling, and only sample the tumor during cutting, thereby improving the accuracy and success rate of sampling.

[0063] During the sampling process, through the combined action of the baffle 4, the first cutter 10 and the second cutter 11, the tumor sample can be cut more quickly and accurately, thereby reducing excessive damage and contamination of the sample. At the same time, the suction cavity 13 can timely suck the blood generated after cutting, keep the surgical field of view clear, and reduce the stimulation and contamination of the surrounding tissues by the blood. In addition, by delivering the disinfectant to the cutting area, the aseptic state of the surgical area is further ensured, the infection risk is effectively reduced, and the safety of sampling is improved.

[0065] As shown in the Figure 7 accompanying drawings, the difference from the above embodiment is that a camera 18 is embedded and installed at the top of the sampling tube 1, and the controller is used to receive and store the image information sent by the camera 18.

[0066] The specific implementation process is as follows:

[0067] The design of the camera 18 can provide real-time image feedback, enabling the doctor to intuitively see the specific situation of the sampling site during the operation; it helps to more accurately locate the tumor position and improve the accuracy and effectiveness of sampling.

[0068] Embodiment 3:

[0069] As shown in the Figure 7 accompanying drawings, the difference from the above embodiment is that a lighting lamp 19 is also fixedly bonded to the top of the sampling tube 1, and the controller is used to control the opening and closing of the lighting lamp 19.

[0070] The specific implementation process is as follows:

[0071] The design of the lighting lamp 19 can provide sufficient light during the operation to ensure that the sampling area is clearly visible, thereby facilitating the improvement of the operation accuracy.

[0072] Embodiment 4:

[0073] As shown in the Figure 2 accompanying drawings, the difference from the above embodiment is that a suction pump 20 is also connected to the end of the sampling tube 1 far from the opening, and the controller is used to control the opening and closing of the suction pump 20; the input end of the suction pump 20 is connected to the opening.

[0074] The specific implementation process is as follows:

[0075] The design of the suction pump 20 can suck out the sample after the tumor sample is cut, thereby improving the sampling efficiency of the sample.

[0076] Embodiment 5:

[0077] As shown in the Figure 2As shown in the figure, the difference from the above embodiment is that a refrigerator 21 is further provided at one end of the sampling tube 1 far from the opening, and the controller is used to control the opening and closing of the refrigerator 21; the output end of the refrigerator 21 is communicated with the opening.

[0078] The specific implementation process is as follows:

[0079] Through the design of the refrigerator 21, the sample can be quickly frozen after sampling, so as to maintain the activity of the sample.

[0080] Obviously, the above embodiments are only examples for clear illustration, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
