Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a puncture-type tumor tissue cutting and extraction device. Background Art

[0002] Tumor tissue refers to the diseased tissue formed due to abnormal proliferation or differentiation of cells, usually manifested as a population of cells with uncontrolled growth. Tumors can be divided into two types: benign and malignant. Among them, malignant tumors are usually more threatening due to their high invasiveness and metastasis, and their early diagnosis and treatment are crucial for the survival rate of patients. The discovery and diagnosis of malignant tumors usually rely on histological examination, that is, extracting tissue samples from the tumor site for pathological analysis. To obtain accurate tumor tissue samples, doctors usually use puncture techniques, and obtain a small piece of tissue from the tumor tissue through a puncture needle for examination.

[0003] Traditional puncture techniques usually rely on blind puncture methods. Doctors operate through experience and image guidance, select the puncture point and insert the puncture needle into the target tissue. However, this blind puncture technique has greater risks. Especially when facing deep tumors or tumors near important tissues such as blood vessels and nerves, the accuracy and safety of the operation are often difficult to guarantee, and it is easy to cause mis-puncture, blood vessel injury or tissue injury, thereby affecting the diagnosis results or causing other complications.

[0034] The optical camera one 5 can directly face forward to ensure the puncture accuracy, is suitable for deep tumors, combines cutting and negative pressure to improve the success rate of tissue extraction, and the outer shape of the puncture needle 1 remains smooth without increasing resistance.

[0035] Please refer to Figures 1-3, the negative pressure mechanism 4 includes a negative pressure tube 401. One end of the negative pressure tube 401 is snap-connected to the extraction tube 3. A piston 403 is slidably connected to the inner wall of the negative pressure tube 401. One end of the piston 403 away from the extraction tube 3 is fixedly connected to a push rod 402. One end of the push rod 402 away from the extraction tube 3 is fixedly connected to a pressing handle 405. The end face of the pressing handle 405 is provided with anti-slip lines. One end of the negative pressure tube 401 away from the extraction tube 3 is provided with a handle 404 for improving the operation stability and comfort.

[0036] Specifically, by means of the pressing handle 405 and in cooperation with the push rod 402, the operator presses or pulls the pressing handle 405 to drive the push rod 402 to move, achieving the effect of facilitating the operator to apply force to control the generation or release of negative pressure; by means of the push rod 402 and in cooperation with the piston 403, when the push rod 402 moves, it drives the piston 403 to slide in the negative pressure tube 401, achieving the effect of generating or eliminating negative pressure in the negative pressure tube 401; by means of the piston 403 and in cooperation with the negative pressure tube 401, the piston 403 slides in the negative pressure tube 401 to change the size of the internal space of the tube, achieving the effect of generating negative pressure to extract tumor tissue samples; by means of the handle 404 and in cooperation with the pressing handle 405, the operator holds the handle 404 and operates the pressing handle 405 at the same time, achieving the effect of improving the operation stability and comfort; by means of the anti-slip lines on the end face of the pressing handle 405 and in cooperation with the operator's hand, the friction between the hand and the pressing handle 405 is increased, achieving the effect of preventing the hand from slipping during operation and improving the operation accuracy.

[0037] Please refer to Figures 1-4 , a scale mark 7 is provided on the outside of the puncture needle 1 for indicating the puncture depth so that the operator can real-time master the depth of the puncture needle 1 entering the tissue.

[0038] Specifically, by means of the scale mark 7 and in cooperation with the puncture needle 1, during the puncture process, the operator observes the scale mark 7 in real time and based on the scale value displayed by it, achieves the effect of accurately mastering the depth of the puncture needle 1 entering the tissue, which helps the operator accurately judge the position of the puncture needle 1 during puncture and avoid unnecessary damage to the surrounding healthy tissues caused by over-puncturing.

[0039] Please refer to Figure 7 , the central control system includes:

[0040] A camera module, connected to the optical camera one 5, for receiving, processing and transmitting real-time images during the puncture process;

[0041] An LED lighting module, connected with a brightness adjustment unit, and the brightness adjustment unit is connected to the LED lamp one 6 for adjusting the brightness of the LED lamp according to actual needs;

[0042] A wireless communication module for wirelessly transmitting camera images and the status of LED lighting lamps to an external monitoring device or an operation terminal.

[0043] Specifically, through the camera module, in cooperation with the optical camera 1-5, the optical camera 1-5 collects images during the puncture process in real time. The camera module receives, processes, and transmits these images, achieving the effect of providing the operator with clear and real-time images of the puncture site to assist in accurately judging the puncture progress; through the LED lighting module and the brightness adjustment unit, in cooperation with the LED lighting lamp 1-6, according to the actual puncture environment and light requirements, the operator uses the brightness adjustment unit to adjust the LED lighting module, thereby changing the brightness of the LED lighting lamp 1-6, achieving the effect of providing suitable lighting conditions for the puncture operation and improving visibility; through the wireless communication module, in cooperation with the camera module and the LED lighting module, the wireless communication module wirelessly transmits the images processed by the camera module and the status information of the LED lighting lamp 1-6 fed back by the LED lighting module to an external monitoring device or an operation terminal, achieving remote data transmission and interaction, facilitating the operator to conveniently view the puncture situation and lighting status on an external device, and facilitating subsequent analysis and record tracing.

[0044] Embodiment 2:

[0045] Please refer to Figure 7 , and further includes: an optical camera 2-8 and an LED lighting lamp 2-9. The LED lighting lamp 2-9 and the optical camera 2-8 are sequentially installed on the outer wall of the puncture needle 1 near the tip end. The optical camera 2-8 and the LED lighting lamp 2-9 are also connected to the central control system.

[0046] Specifically, the optical camera 2-8 and the LED lighting lamp 2-9 are connected to the central control system. The optical camera 2-8 collects images of the outer wall of the puncture needle 1 and transmits them to the camera module of the central control system. After being processed by the module, they are sent to an external device via the wireless communication module to assist the operator in grasping the surrounding situation; the LED lighting lamp 2-9 is controlled by the LED lighting module of the central control system. When the light is dim, the operator commands the LED lighting module through the brightness adjustment unit. The module adjusts the current to change the brightness of the lamp, creating conditions for the optical camera 2-8 to collect light. Its brightness status is also fed back to the central control system and is available for the operator to monitor via the wireless communication module.

[0047] The lateral optical camera 2-8 can observe the surrounding tissues to avoid accidentally injuring blood vessels or nerves, especially in areas close to blood vessels such as the liver and pancreas, which can avoid intraoperative risks. The doctor can fine-tune the direction during the process to improve safety.

[0048] Working principle: First, press the pressing handle 405, and the push rod 402 moves accordingly, causing the piston 403 to move in the negative pressure tube 401. Continuing to press the pressing handle 405 moves the piston 403 to the end of the negative pressure tube 401 near the extraction tube 3. Subsequently, the operator holds the handle 404 of the negative pressure mechanism 4. Since there are scale markings 7 on the outer side of the puncture needle 1, by observing the scale markings 7, the operator can pre-plan the puncture depth. At the same time, the LED lighting module of the central control system is connected to the first LED lighting lamp 6 through the brightness adjustment unit. According to the actual puncture environment, the operator can adjust the brightness of the first LED lighting lamp 6 through the brightness adjustment unit to provide appropriate lighting conditions for the puncture site to facilitate subsequent operation and observation.

[0049] The operator holds the negative pressure tube 401 by hand, aligns the puncture needle 1 with the tumor tissue site to be punctured, and then pushes the puncture needle 1 to perform the puncture. During the puncture process, the first optical camera 5 and the first LED lighting lamp 6 are both connected to the central control system. The first LED lighting lamp 6 illuminates the puncture site, and the first optical camera 5 real-time collects images of the puncture site and transmits the image information to the camera module of the central control system. The camera module receives, processes, and transmits these real-time images. The operator can observe the puncture situation of the puncture needle 1 in real time through an external monitoring device (image transmission is achieved through the wireless communication module of the central control system), and grasp the depth of the puncture needle 1 entering the tissue in real time according to the scale markings 7 to ensure that the puncture needle 1 accurately reaches the tumor tissue position.

[0050] When the puncture needle 1 reaches the appropriate position, since there is a cutting blade 2 on the inner wall of the puncture needle 1 near the tip, one end of the cutting blade 2 is fixedly connected to the inner wall of the sampling cylinder, and there is a certain gap between the other end and the inner wall of the sampling cylinder. At this time, rotate the negative pressure tube 401 (one to two turns are sufficient), and use the cutting edges on both sides of the cutting blade 2 to cut the tumor tissue and cut off the tumor tissue.

[0051] After the cutting is completed, the operator holds the pressing handle 405 and pulls it in the direction away from the extraction tube 3. This will drive the push rod 402 to move, and then drive the piston 403 to slide in the negative pressure tube 401, causing a negative pressure to be generated in the negative pressure tube 401. Since one end of the negative pressure tube 401 is snap-connected to the extraction tube 3, and the extraction tube 3 is fixedly connected to the inner wall of the puncture needle 1, the negative pressure will be transmitted to the inside of the puncture needle 1 through the extraction tube 3, thereby sucking the cut tumor tissue sample into the extraction tube 3 through the puncture needle 1.

[0052] After the extraction is completed, the puncture needle 1 is withdrawn from the tissue, and the pressing handle 405 is continuously pulled to allow the tumor tissue sample to enter the negative pressure tube 401. At this time, the extraction tube 3 can be removed from the negative pressure tube 401, and the tumor tissue sample can be conveniently taken out from the negative pressure tube 401, thus completing a puncture-type tumor tissue cutting and extraction operation. During the whole process, the wireless communication module of the central control system will wirelessly transmit information such as the camera image and the status of the LED lighting to an external monitoring device, which is convenient for the operator to perform subsequent analysis and judgment, and is also convenient for recording and tracing the operation process.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
