Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a puncture guiding device and system for thoracic surgery. Background Art

[0002] In the scope of thoracic surgery, for common operations such as pleural effusion drainage, lung biopsy, pneumothorax treatment, etc., puncture is a key step, which is directly related to the surgical outcome and the patient's prognosis; the traditional thoracic puncture method largely relies on the experience accumulated by doctors over the years and the subtle touch of their hands. Currently, due to the lack of a guiding device, traditional thoracic puncture is performed only by the doctor's naked-eye observation and experience judgment, and the accuracy of puncture is greatly reduced; with a slight deviation, a series of difficult problems are likely to occur; on the one hand, it may accidentally damage important surrounding tissues and organs, such as puncturing blood vessels causing massive bleeding, damaging nerves resulting in local sensory or motor dysfunction after surgery, and puncturing lung tissue causing secondary injuries such as pneumothorax, which will not only greatly increase the patient's pain and prolong the postoperative recovery time, but may even endanger the patient's life; on the other hand, inaccurate puncture often means puncture failure and multiple repeated operations have to be carried out. Each repeated puncture causes additional pain to the patient and also prolongs the operation time. During the long operation process, various surgical risks such as infection risk and anesthesia risk faced by the patient also increase; therefore, the present invention provides a puncture guiding device and system for thoracic surgery to fill the gap in clinical needs and effectively ensure the surgical safety and treatment effect of patients.

The two sets of clamping plates are driven by the booster threaded rod B to perform secondary fixation on the puncture needle. The clamping rubber pad can increase the friction to prevent the puncture needle from sliding and avoid damage to the puncture needle, thereby ensuring that the puncture needle always remains stable after puncture, and the puncture can be maintained even when encountering certain external force interference.

[0012] In the present invention, the camera in the monitoring component has automatic focus and anti-shake functions, which can capture clear and stable images of the chest puncture site in real time. The image enhancement algorithm of the image processor optimizes the collected images, so that medical staff can intuitively see the subtle structures of the puncture site on the display screen, such as organ contours, blood vessel directions, etc. The tissue recognition software based on deep learning (which can be integrated in the image processor) can also automatically identify key tissue structures and mark them, providing accurate reference for puncture path planning, helping medical staff avoid dangerous areas, and further improving the safety and success rate of puncture.

A fixing nut C702 for adjusting the tightness of the universal rotating ball 703 is arranged on the surface of the universal rotating housing 701 in a threaded manner. A rubber nut 706 is connected to the surface of the guiding cannula 705 in a threaded manner. The puncture needle passes through the guiding cannula 705 and then punctures into the patient's body.

[0019] Referring to Figure 3 , the stability assembly includes an L-shaped support plate 9. The L-shaped support plate 9 is fixedly installed on the inner wall of the fixed frame 2. A sliding groove 10 is formed on the surface of the L-shaped support plate 9. A guiding rod 12 is spliced and slidably arranged in the sliding groove 10. One end of the guiding rod 12 is fixedly connected to the adjustment block 5, and the other end is fixedly connected to the limiting plate 11. It is worth noting that the combination of the L-shaped support plate 9, the sliding groove 10 and the guiding rod 12 enables the adjustment block 5 to slide smoothly up and down within the fixed frame 2, providing a stable structural support for further adjusting the height of the puncture needle. The movement of the adjustment block 5, in cooperation with the boosting threaded rod A4, enables medical staff to accurately control the initial height position of the puncture needle, ensuring that the puncture operation starts from the best starting point.

[0022] Referring to Figures 1-5 , the monitoring assembly 8 includes a base 801. The base 801 is fixedly installed on the surface of the mounting block 3. The surface of the base 801 is fixedly connected to a camera 803 through a corrugated pipe 802. The camera 803 has functions of automatic focusing and anti-shake, and can clearly capture the real-time image of the thoracic puncture site. The camera 803 is connected to an external image processor through a data cable.

The image processor is connected to the display screen in the operating room, and medical staff can intuitively view the situation of the puncture site. The monitoring assembly 8 constitutes a monitoring system.

[0023] Referring to Figure 2, the support adjustment assembly 1 includes a fixed sleeve rod 101. The bottom of the fixed sleeve rod 101 is slidably inserted into the fixed sleeve column 102. A fixed nut A 103 is provided on the surface of the fixed sleeve column 102 in a threaded manner. The bottom surface of the fixed sleeve column 102 is rotatably connected to the clamping frame 104. The bottom surface of the clamping frame 104 is threadedly connected to the boosting screw rod C 106. The top end of the boosting screw rod C 106 is rotatably connected to the gasket 105.

[0024] Referring to Figure 2 , a groove is formed inside the top of the fixed sleeve rod 101, and a sliding rod 107 is spliced and slidably arranged in the groove. A fixed nut B 108 is provided on the outer side of the top of the fixed sleeve rod 101 in a threaded manner, and the other end of the sliding rod 107 is fixedly connected to the surface of the fixed frame 2.

[0025] In the present invention, according to the patient's body position, by rotating the fixed nut A 103, the insertion depth of the fixed sleeve rod 101 in the fixed sleeve column 102 is adjusted, so as to adjust the height of the whole device; then, the clamping frame 104 is rotated to a suitable angle so that it can be clamped on the edge of the operating table, and the boosting screw rod C 106 is rotated to make the gasket 105 contact the operating table and tightened, so as to firmly clamp the clamping frame 104 on the edge of the bed; then, by rotating the fixed nut B 108, the position of the sliding rod 107 in the groove is adjusted, and further the position of the fixed frame 2 in the horizontal direction is adjusted to meet the specific requirements of the operation; According to the anatomical structure inside the patient's chest cavity and the specific requirements of the operation, the guiding cannula 705 is rotated to drive the universal rotating ball 703. Through the cooperation of the universal rotating shell 701 and the universal rotating ball 703, the angle of the guiding cannula 705 is adjusted. After adjusting to a suitable angle, the fixed nut C 702 is rotated to make it tightened, so as to fix the position of the universal rotating ball 703, and thus fix the angle of the guiding cannula 705; The medical staff pushes the puncture needle along the predetermined puncture path, so that it passes through the guiding cannula 705 and punctures into the patient's body. Since the inner diameter of the guiding cannula 705 is adapted to the puncture needle, the puncture needle is stably supported inside the guiding cannula 705; when the puncture is completed, the rubber nut 706 can be optionally rotated to tighten the puncture needle to prevent the puncture needle from accidentally falling out or shifting during the puncture process; among them, the secondary clamping assembly 13 can be selectively used. By rotating the boosting screw rod B 14, the boosting screw rod B 14 threadedly penetrates through the L-shaped support plate 9 and drives the clamping plate 15 to move. The two clamping plates 15 gradually approach the puncture needle under the drive of the boosting screw rod B 14 until the clamping rubber pad 16 is in close contact with the puncture needle to perform secondary fixation on the puncture needle; It is worth mentioning that during the puncture process, camera 803 is turned on. Since camera 803 has automatic focus and anti-shake functions, it can capture clear and stable images of the chest puncture site in real time. Camera 803 transmits the collected images to an external image processor via a data cable. The image processor has a built-in image enhancement algorithm to perform noise reduction, contrast adjustment and other processing on the collected images to make the image details clearer; the image processor is connected to the display screen in the operating room, and medical staff can intuitively view the situation of the puncture site on the display screen, including organ contours, blood vessel directions and other subtle structures; deep learning-based tissue recognition software (integrated in the image processor) can automatically identify and mark key tissue structures, provide accurate reference for puncture path planning, and help medical staff avoid dangerous areas to ensure the safety and success rate of puncture.
