Description

Technical Field

[0001] The invention relates to medical instruments, in particular to an intestinal tumor position marking device for finding lesions during laparoscopic surgery. Background Art

[0002] During laparoscopic surgery, precise localization of intestinal tumors is crucial for successful surgery. Traditional methods rely on preoperative imaging studies (such as CT and colonoscopy) to mark the tumor location. However, the peristaltic nature and flexibility of the intestine can easily cause it to shift during surgery, leading to a discrepancy between preoperative markings and the actual lesion location, increasing the difficulty of the procedure.

[0003] Existing intraoperative marking technology has obvious limitations: First, when using injected dye for marking, the dye easily diffuses with the peristalsis of the intestinal wall, making it difficult to maintain accurate positioning for a long time, especially for marking tiny tumors; second, when manually placing markers such as metal clips, the position needs to be repeatedly adjusted using laparoscopic instruments, which is cumbersome and time-consuming, increasing the risk of intestinal damage; third, some marking devices lack real-time visual guidance and rely on the doctor's experience to judge the marking position, which can easily lead to marking failure due to operational errors.

[0004] Furthermore, conventional devices lack mechanical stability, making marker release difficult to control within the confined abdominal cavity. This can lead to marker detachment or excessive embedding, compromising the accuracy of subsequent surgical resection. These drawbacks not only prolong surgery time but can also result in residual tumor or excessive resection of normal tissue, compromising surgical safety and patient outcomes. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to ensure that the marker can be stably attached to the side of the tumor, avoid deviation between the preoperative marking and the actual position during surgery, and at the same time utilize the stability of metal titanium beads to achieve long-term precise positioning, providing a reliable reference for surgical resection; another purpose of the present invention is to achieve automatic release of the marker and reduce errors caused by manual operation; at the same time, through multiple elastic positioning components, the release force of the marker is ensured to be uniform and controllable, reducing the risk of intestinal damage.

[0006] Technical solution: A device for marking the position of intestinal tumors for finding lesions during laparoscopic surgery includes a hand grip, the front surface of the hand grip is fixedly connected to a metal memory rod, the front end of the metal memory rod is fixedly connected to an outer cavity, the rear surface of the outer cavity is provided with a cavity, the cavity is an internal hollow structure, and the interior of the cavity is fixedly connected to a partition.

[0007] Furthermore, a bead outlet is provided on the rear surface of the partition, a bead outlet tube is fixedly connected to the left side of the bead outlet, a rotating rod is fixedly connected to the right side of the partition, a turntable is fixedly connected to the outer wall of the turntable, a bead leakage outlet is provided on the rear surface of the turntable, a titanium bead guide groove is provided on the outer wall of the bead leakage outlet on the rear surface of the turntable, a support plate is fixedly connected to the outer wall of the rotating rod on the right side of the interior of the cavity, and a gear is fixedly connected to the right end of the rotating rod on the right side of the support plate.

[0008] Furthermore, the rear surface of the support plate is fixedly connected to a circular plate inside the cavity, the right side of the circular plate is fixedly connected to a motor, the output end of the motor is fixedly connected to a transmission rod, the left end of the transmission rod extends to the rear surface of the support plate and is fixedly connected to a cam, and the outer side wall of the cam is provided with a transmission tooth groove.

[0009] Furthermore, the rear surface of the support plate is symmetrically provided with spring grooves, the interior of the spring grooves is slidably connected to slide rods, the opposite ends of the slide rods are fixedly connected to locking elliptical heads, and the slide rods are fixedly connected to the interior of the spring grooves with springs.

[0010] Furthermore, an extrusion groove is provided on the front surface of the turntable, a round block is fixedly connected to the inside of the extrusion groove, a short column is fixedly connected to the front surface of the round block, a limiting ring is fixedly connected to the left side of the short column, an elastic ring is wrapped around the outer wall of the short column, the front end of the elastic ring is fixedly connected to the rear surface of the limiting ring, the rear end of the elastic ring is fixedly connected to the front surface of the round block, and the outer wall of the short column is slidably connected to an extrusion protrusion.

[0011] Furthermore, the inner side wall of the bead outlet is fixedly connected with a plurality of blocking soft protrusions.

[0012] Furthermore, a micro camera is symmetrically fixedly connected to the front surface of the partition, and a fill light is fixedly connected to the top of the front surface of the partition.

[0013] Furthermore, a handle is fixedly connected to the outer side wall of the handle bar, and a motor start button is fixedly connected to the right side of the handle bar.

[0014] Beneficial effects: The device greatly improves the accuracy of tumor position marking through the synergistic effect of multiple structures. First, the micro camera on the front surface of the partition, combined with the fill light, can clearly capture the position of the tumor in the intestinal cavity in real time, providing an accurate visual reference for the selection of marking points. Secondly, the titanium bead guide groove on the rear surface of the turntable can standardize the movement trajectory of the titanium beads, ensuring that the titanium beads accurately move toward the bead outlet. When the bead outlet is aligned with the bead outlet, the spring in the spring groove pushes the slide bar so that the locking elliptical head lightly touches the turntable, and cooperates with the contact positioning of the extrusion protrusion and the locking elliptical head to achieve high-precision docking between the bead outlet and the bead outlet. In addition, the blocking soft protrusion on the inside of the bead outlet can prevent the titanium beads from falling prematurely, further ensuring that the titanium beads are released only when they are precisely aligned, effectively reducing the risk of marking failure due to positioning deviation, and providing a reliable basis for subsequent surgery to accurately remove the lesions.

[0015] The device performs outstandingly in terms of operational stability and titanium bead release reliability. When the doctor holds the hand grip, the outer handle can provide a stable grip fulcrum to reduce hand shaking during operation, especially in the narrow operating space of laparoscopic surgery, which can improve the overall control stability of the device. In the titanium bead release link, the combined structure of the extrusion bump and the elastic ring plays a key role: when the extrusion bump contacts the titanium bead, the elastic ring on the short column generates an auxiliary thrust through elastic deformation, and cooperates with the direct extrusion of the extrusion bump to form a stable and controllable release force, avoiding the titanium bead from being retained due to insufficient thrust or deviating from the target position due to excessive thrust. At the same time, the stable support of the rotating rod by the support plate and the meshing transmission of the cam and the gear ensure the smooth rotation of the turntable, significantly improving the reliability and consistency of the marking operation.

A motor 31 is fixedly connected to the right side of the circular plate 30, and the output end of the motor 31 is fixedly connected to a transmission rod 14. The left end of the transmission rod 14 extends to the rear surface of the support disk 12 and is fixedly connected to a cam 15. A transmission tooth groove 16 is provided on the outer wall of the cam 15. A spring groove 17 is symmetrically provided on the rear surface of the support disk 12. The inside of the spring groove 17 is slidably connected with a slide rod 18, and the opposite end of the slide rod 18 is fixedly connected with a locking elliptical head 20. A spring 21 is fixedly connected between the slide rod 18 and the inside of the spring groove 17. A plurality of blocking soft protrusions 27 are fixedly connected to the inner side wall of the bead outlet 6. A miniature camera 28 is symmetrically fixedly connected to the front surface of the partition 5, and a fill light 29 is fixedly connected to the top of the front surface of the partition 5. During operation, the doctor holds the hand grip 1 and adjusts the position of the outer cavity 3 in the intestinal cavity through the moldable metal memory rod 2. The cavity 4 inside the outer cavity 3 is the core working area. The partition 5 separates the cavity 4. The micro camera 28 on its front surface captures the tumor position in real time. The fill light 29 provides sufficient lighting to ensure accurate positioning. After determining the marking point, the motor 31 starts and drives the cam 15 to rotate through the transmission rod 14. The transmission tooth groove 16 on the outside of the cam 15 engages with the gear 13, causing the rotating rod 8 to rotate, thereby driving the turntable 9 to rotate synchronously. The titanium bead guide groove 11 on the turntable 9 guides the movement of the titanium beads. When the bead outlet 10 is aligned with the bead outlet 6 of the partition 5, the titanium beads enter the bead outlet tube 7 through the bead outlet 6. The blocking soft protrusion 27 on the inside of the bead outlet 6 can prevent the titanium beads from falling out. The support plate 12 provides stable support for the rotating rod 8, and the circular plate 30 fixes the position of the motor 31. During the rotation of the turntable 9, the spring 21 in the spring slot 17 pushes the slide bar 18, causing the locking elliptical head 20 to lightly touch the turntable 9, assisting in positioning and ensuring that the bead outlet 10 and the bead outlet 6 are accurately aligned.

[0020] In this embodiment, an extrusion groove 22 is opened on the front surface of the turntable 9, a round block 23 is fixedly connected to the inside of the extrusion groove 22, a short column 24 is fixedly connected to the front surface of the round block 23, a limit ring 25 is fixedly connected to the left side of the short column 24, an elastic ring 26 is wound around the outer wall of the short column 24, the front end of the elastic ring 26 is fixedly connected to the rear surface of the limit ring 25, the rear end of the elastic ring 26 is fixedly connected to the front surface of the round block 23, an extrusion protrusion 19 is slidably connected to the outer wall of the short column 24, a handle 32 is fixedly connected to the outer wall of the hand lever 1, and a motor start button 33 is fixedly connected to the right side of the hand lever 1; When holding the handgrip 1, the doctor grasps the outer handle 32 for stable operation. By pressing the motor start button 33 on the right side of the handgrip 1, the motor 31 is activated. As the turntable 9 rotates, the extrusion groove 22 on its front surface rotates synchronously with the turntable. The circular block 23 inside the extrusion groove 22 secures the short column 24, and the extrusion protrusion 19 outside the short column 24 can slide along the column. When the turntable 9 rotates until the bead outlet 10 is aligned with the bead outlet 6, the extrusion protrusion 19 moves exactly to the position of the titanium bead, squeezing the titanium bead. At the same time, the extrusion protrusion 19 contacts the locking elliptical head 20, compressing the elastic ring 26 on the short column 24. The front end of the elastic ring 26 is fixed to the limiting ring 25. The elastic force generated by the elastic deformation assists the extrusion protrusion 19 to exert force, and the titanium ball is ejected from the bead outlet 6 through the bead outlet tube 7. This structure cooperates with the spring 21 in the elastic groove 17 to ensure the smooth rotation of the turntable 9, and enhances the positioning accuracy when the bead outlet 10 and the bead outlet 6 are docked, further improving the stability and strength of the titanium ball release.
