Description

Technical Field

[0001] The present invention relates to the technical field of abdominal surgery puncture techniques, and particularly to an abdominal surgery puncture device. Background Art

[0002] In hepatobiliary surgery, laparoscopic surgery and puncture techniques are often combined. For example, when there is a mass in the liver but its nature (such as benign or malignant) cannot be determined, laparoscopic liver biopsy is performed under the guidance of ultrasound or CT, and tissue is taken for pathological examination to determine the nature of the mass, so as to formulate subsequent treatment plans.

[0003] During the puncture of existing laparoscopic surgeries in hepatobiliary surgery, since there are multiple layers of tissues in the abdominal wall and the resistance of each layer of tissue is different, the change in resistance felt during the puncture process is different. For example, when the puncture needle touches the abdominal wall, there will be a certain initial resistance. As the force is applied to push forward, after penetrating the skin and subcutaneous tissue, the resistance will slightly decrease. When approaching the peritoneum, the resistance will increase again, which makes it difficult for doctors to precisely control the force by hand feeling. Often, due to the sudden decrease in resistance during puncture, the puncture is too deep, further resulting in tissue damage, bleeding, liver injury and postoperative complications for patients. Therefore, we propose an abdominal surgery puncture device. Summary of the Invention

[0048] The synchronizing member 55 includes spherical blocks 551. There are two spherical blocks 551. In this embodiment, the rotating block 54 is arranged in a cylindrical shape. At the same time, a hollow cavity is provided inside the rotating block 54, so as to reduce the weight of the rotating block 54 and ensure that the rotating rod 56 drives the rotating block 54 to rotate stably.

The electromagnet 62 is in a ring shape, and the outer ring of the electromagnet 62 is fixedly connected to the inner wall of the partition shell 61;

[0050] The positioning member 63 is installed outside the rotating rod 56, and when the electromagnet 62 is energized, the positioning member 63 is electrically connected to the electromagnet 62;

[0051] The patch type rotating shaft speed sensor 64 is located outside the top of the partition shell 61, and the patch type rotating shaft speed sensor 64 is installed on the rotating rod 56. The hand-rotating plate 65 is fixedly installed on the top of the rotating rod 56;

[0052] The positioning member 63 includes a positioning shell 631, a plastic spring 632 and an iron block 633. The positioning shell 631 is fixedly sleeved outside the rotating rod 56, and installation openings 6311 are respectively provided at both ends of the positioning shell 631. There are multiple plastic springs 632. One ends of the multiple plastic springs 632 are fixedly installed inside the installation openings 6311, and the other ends of the multiple plastic springs 632 are fixedly connected to the iron block 633. The iron block 633 slides through the installation openings 6311;

[0053] Specific implementation process: When performing laparoscopic surgery puncture in hepatobiliary surgery, first disinfect the puncture site. Then, install the puncture needle tube 21 on the outer sleeve 11. At this time, align one end of the outer sleeve 11 with the puncture site, and at the same time, use one hand to fix the outer sleeve 11 and the puncture site, and use the other hand to rotate the hand turning plate 65. While the hand turning plate 65 rotates, the rotating rod 56 rotates. While the rotating rod 56 rotates, on the one hand, the patch type rotating shaft speed sensor 64 on the rotating rod 56 is used to detect the rotation speed of the rotating rod 56. On the other hand, the rotating rod 56 synchronously drives the rotating block 54 to rotate. While the rotating block 54 rotates, the two consecutive V-shaped grooves 541 on its outer side rotate synchronously. At this time, due to the limiting effect of the U-shaped plate 51, the two spherical blocks 551 further slide relative to the V-shaped grooves 541. At the same time, under the limiting effect of the two guide blocks 521 and the guide strip 522 on the U-shaped plate 51, the U-shaped plate 51 moves along the inside away from the connecting sleeve 31;

[0054] While the U-shaped plate 51 moves, it pushes one end of the puncture needle tube 21 to insert along the puncture site. And after the rotating rod 56 rotates 180°, the puncture needle tube 21 moves along the inside of the outer sleeve 11 until the hand turning plate 65 returns to its original position, then pushes the outer sleeve 11 to insert along the already punctured position, and then performs the puncture insertion of the next section of length;

[0055] During the puncture process, when the resistance of the internal tissues of the abdominal wall is different, such as when the doctor rotates the hand turning plate 65 forcefully, after one end of the puncture needle tube 21 penetrates the skin and subcutaneous tissue, when the patch type rotating shaft speed sensor 64 detects that the rotation speed of the rotating rod 56 exceeds the set value, the electromagnet 62 is energized. Then, the iron blocks 633 at the positioning shell 631 outside the rotating rod 56 are adsorbed on the electromagnet 62 under the magnetic adsorption force of the electromagnet 62, and at the same time, the positioning shell 631 is fixed, and at the same time, the rotating rod 56 is locked. Then, the electromagnet 62 is powered off, and the doctor adjusts the turning force and slowly rotates the rotating rod 56 again, so that the puncture needle tube 21 is slowly inserted into the required puncture position and then retracted according to the micro camera 22 on the puncture needle tube 21. Then the doctor inserts the outer sleeve 11 into the puncture position;

[0056] Therefore, in the present invention, changing the existing direct pressing type insertion of the puncture needle tube 21 to a rotating insertion of the puncture needle tube 21 can well control the stability of the insertion of the puncture needle tube 21, and at the same time prevent the phenomenon that the puncture needle tube 21 penetrates too deep due to the sudden decrease in resistance and excessive force.

[0057] Embodiment Two

[0058] Please refer toFigures 10 to 11 , Embodiment 2 further supplements and explains Embodiment 1. Specifically, an arc-shaped opening 651 is provided on the hand-rotating plate 65. In this embodiment, the hand-rotating plate 65 is arranged in a stepped manner, that is, two steps are provided, and the arc-shaped opening 651 is located at one step close to the partition shell 61. A positioning ball 66 is clamped at the arc-shaped opening 651, and a support member 7 for connecting the positioning ball 66 is installed on the top of the partition shell 61;

[0059] The support member 7 includes a support sleeve 71, a support spring 72, and a support rod 73. The support sleeve 71 is fixedly installed on the partition shell 61, and one end of the support spring 72 is fixedly installed inside the support sleeve 71. The other end of the support spring 72 is fixedly connected to the support rod 73. The support rod 73 slidably penetrates through the support sleeve 71, and the other end of the support rod 73 is connected to the positioning ball 66;

[0060] That is, when one end of the puncture needle tube 21 is in the state inside the outer sleeve tube 11, the positioning ball 66 is clamped at the arc-shaped opening 651 on the hand-rotating plate 65 due to the reverse elastic force of the support rod 73 and the support spring 72. Subsequently, when the hand-rotating plate 65 is rotated, as the hand-rotating plate 65 rotates, the positioning ball 66 disengages from the arc-shaped opening 651. Then, until the hand-rotating plate 65 rotates 180°, the puncture needle tube 21 extends the farthest distance from the outer sleeve tube 11. As the hand-rotating plate 65 continues to rotate until the arc-shaped opening 651 is clamped with the positioning ball 66 again, the doctor further inserts the outer sleeve tube 11 into the position where the puncture needle tube 21 has completed the puncture under the illumination of the micro camera 22.
