AI Technical Summary
After the existing lung nodule removal forceps remove the lung nodules, the surgical cavity is prone to bleeding, which affects healing and increases the pain of the patient.
A percutaneous pulmonary puncture injectable spherical device for lung nodules was designed. It combines an injection tube and hemostatic gel. The surgical cavity is filled and hemostasis is stopped while the nodule is removed by resection forceps, and the arc groove design is used for clamping and wrapping resection.
While removing the lung nodules, the surgical cavity is quickly filled and hemostasis is achieved, which reduces the postoperative recovery time and avoids secondary injuries.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and more particularly to an injectable spherical device for percutaneous lung puncture of lung nodules. Background Art
[0002] Pulmonary nodules are focal, round, dense shadows of varying sizes, with clear or blurred margins and a diameter of 3 cm or less on lung images. During thoracoscopic surgery, most pulmonary nodules are less than 1 cm in diameter, and some are located on the lung surface. These nodules are typically treated with minimally invasive procedures.
[0003] However, after the lung nodule is removed using the current lung nodule removal forceps, a surgical cavity will be left inside, which will continue to bleed, affect healing, and increase the patient's pain.
[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention
[0005] The purpose of the present invention is to provide a percutaneous lung puncture pulmonary nodule injectable spherical instrument. The percutaneous lung puncture pulmonary nodule injectable spherical instrument has a simple structure and can further fill and stop bleeding in the surgical cavity while removing the nodule, thereby accelerating postoperative recovery.
[0006] The present invention provides an injectable spherical instrument for percutaneous lung puncture of lung nodules, comprising a clamp body, a fixed handle, a movable handle, a fixed tube, a movable tube, a coil spring, a resection forceps, an injection tube, a connecting tube and a syringe; the fixed handle is fixedly connected to a side surface of the clamp body, and the movable handle is rotatably provided on the side surface of the clamp body; a linkage rod is provided on one end of the movable handle located at the clamp body, one end of the clamp body is fixedly connected to the fixed tube, the movable tube is inserted into the fixed tube, one end of the movable tube is connected to the resection forceps, and the other end of the movable tube is connected to the linkage rod; the injection tube is located in the movable tube, one end of the injection tube passes through the side of the resection forceps, the other end of the injection tube passes through the tail of the clamp body and is connected to the connecting tube, and the other end of the connecting tube is connected to the syringe; one end of the coil spring is fixed to the clamp body, and the other end of the coil spring is fixed to the movable handle, and is used to control the movable handle to rotate around the clamp body, thereby pushing the resection forceps at the end of the movable tube to extend from the fixed tube through the linkage rod, and the extended resection forceps remains in an open state.
[0007] By adopting the above technical solution, under normal conditions, the resection forceps is located outside the fixed tube and remains in an open state; by pressing the movable handle, the movable handle will rotate around the forceps body, and the linkage rod will pull the resection forceps opened at the end of the movable tube to retract. At this time, the resection forceps are clamped together to remove the nodule. At this time, medical hemostatic gel is injected into the surgical cavity after resection through the syringe, the connecting tube and the injection tube, so that the surgical cavity is further filled and hemostasis is achieved during resection, thereby accelerating postoperative recovery.
[0008] Furthermore, the resection pliers includes a first pliers head and a second pliers head; the first pliers head and the second pliers head are hook-shaped, the tails of the first pliers head and the second pliers head are fixedly connected, and the tails of the first pliers head and the second pliers head are both connected to the movable tube; in a normal state, the first pliers head and the second pliers head are opened; when the movable handle is pressed, the movable handle will rotate around the pliers body, and the linkage rod will pull the first pliers head and the second pliers head opened at the end of the movable tube back into the fixed tube, and at this time the first pliers head and the second pliers head are closed.
[0009] Furthermore, arc-shaped grooves are provided on the inner walls of the ends of the first clamp head and the second clamp head.
[0010] By adopting the above technical solution, the design of the arc-shaped groove enables the nodule to be clamped and wrapped when the lung nodule is removed. When the first and second forceps are clamped, the two arc-shaped grooves form a circle, completely covering the nodule, and no secondary damage will be caused to the patient during removal and removal after resection.
[0011] The percutaneous lung puncture pulmonary nodule injectable spherical instrument of the present invention, the design of the injection tube, connecting tube and syringe, can further fill the surgical cavity and stop bleeding while removing the nodule, thereby accelerating postoperative recovery; the design of the arc-shaped groove can clamp and wrap the nodule when removing the lung nodule, and the removal is very convenient, which solves the problem that the current clamping device is very inconvenient to use; when the first forceps head and the second forceps head are clamped, the two arc-shaped grooves form a circle, which completely covers the nodule, and will not cause secondary damage to the patient during removal and removal after removal.
