Description

TECHNICAL FIELD

[0001] The present application relates to the field of surgical instruments, in particular to a magnetic line system applied to thoracoscope surgery. BACKGROUND

[0002] Thoracoscope surgery is a minimally invasive thoracic surgery technology. Doctors make 1-3 small holes in the chest wall of the patient, insert a camera lens and an elongated instrument into the chest cavity, and watch the high-definition display screen to operate. It is mainly used for the diagnosis and treatment of lung, esophagus, mediastinum and other chest diseases, and has the advantages of small trauma, light pain and fast recovery.

[0003] In the process of thoracoscope surgery, suturing is a core link throughout the process. The main scenes include: key structure closure, tissue reconstruction, complication handling, etc. However, traditional suturing mainly relies on mechanical needle holders, which has the following disadvantages: ① Mechanical clamping causes tissue damage: the clamping of the needle and the surrounding fragile tissue by the clamp directly causes extrusion and tearing, increasing the risk of bleeding; ② Difficulty in operating in deep and narrow space: in a single hole or deep surgical field, the instrument has low freedom of movement, is easy to entangle, and is difficult to accurately control the angle and force of the needle, affecting the quality and efficiency of suturing; ③ Poor emergency handling capability: once the needle or suture is accidentally dropped into the chest cavity, the traditional instrument takes a long time to search and pick up, greatly interfering with the operation rhythm. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a magnetic line system applied to thoracoscope surgery by changing the needle holding and line holding method to optimize the suturing effect.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a suture line comprising a suture needle at the front end, a guide sleeve, a magnetic line guide and a magnetic anchor point, the suture needle and the magnetic anchor point are both made of magnetic metal material, the magnetic anchor point is located at the tail end of the suture line, the front end of the magnetic line guide is provided with an electromagnet that attracts the suture needle or the magnetic anchor point, and the guide sleeve is provided with a guide channel that leads from the outside of the body to the inside of the suture position and allows the magnetic line guide and the suture line to pass through.

[0006] By using the above technical solution, the electromagnet of the magnetic line guide attracts the suture needle, guides the suture line to pass through the guide channel, and completes the suturing of the suture position by multiple suction and release, and cooperates with the magnetic anchor point at the tail end of the suture line to assist the suturing and facilitate the arrangement of the surgical field of view, solving the bleeding risk, easy entanglement, and difficulty in accurately controlling the angle and force of the needle of the traditional mechanical needle holder for suturing, thereby optimizing the suturing effect.

[0007] The present invention is further configured such that: the magnetic lead wire includes a grip rod for hand use, the front end of the grip rod is provided with a simulated finger and a motion simulation mechanism for driving the simulated finger to swing, and the electromagnet is provided at the front end of the simulated finger.

[0008] By adopting the above technical solution, the magnetic thread guide simulates the swinging motion of a finger holding a needle, making the suturing method closer to reality and further optimizing the suturing effect and operational flexibility.

[0009] The present invention is further configured such that: the motion simulation mechanism includes a simulated motor fixed inside the grip rod, the front end of the grip rod is provided with a simulated cavity, the rear end of the simulated finger is located inside the simulated cavity and is provided with a rotating shaft that rotates with the simulated cavity, the rotating shaft is fixedly provided with a driven gear, and the simulated motor is driven by a driving gear that meshes with the driven gear.

[0010] By adopting the above technical solution, the driving gear is driven by a simulated motor to rotate, which in turn drives the driven gear that meshes with the driving gear to rotate, thereby causing the shaft to rotate and realizing the precise swinging of the simulated finger.

[0011] The present invention is further configured such that: a battery and a conductive slip ring are provided inside the grip rod, and the conductive slip ring is installed on the rotating shaft and forms a power supply connection between the battery and the electromagnet.

[0012] By adopting the above technical solution, the conductive slip ring can provide a continuous and stable power supply to the electromagnet through the battery inside the gripping rod, thereby ensuring the reliability of the electromagnet's engagement.

[0013] The present invention is further configured such that: a button for controlling the on / off state of the electromagnet power supply circuit and a knob for adjusting the magnitude of the electromagnet's magnetic force are provided at the rear end of the gripping rod.

[0014] By adopting the above technical solution, the button for controlling the on / off state of the electromagnet power supply circuit and the knob for adjusting the magnitude of the electromagnet's magnetic force are integrated into the rear end of the grip rod, making the operation of medical staff more convenient and precise.

[0015] The present invention is further configured such that the surface of the electromagnet is covered with an insulating coating.

[0016] By adopting the above technical solution, an insulating coating is added to the surface of the electromagnet to meet the medical device specifications for preventing current conduction.

[0017] The present invention is further configured such that the surface of the suture needle has fluorescent markers.

[0018] By adopting the above technical solution, fluorescent markers are added to the suture needles, and the position of the suture needles is accurately tracked with the help of a fluorescent tracking device. If a suture needle or suture accidentally falls out into the chest cavity, it can be quickly found and retrieved with the help of a magnetic suture guide, reducing interference with the surgery.

[0022] like Figure 1 — Figure 3As shown, this invention discloses a magnetic suture system for thoracoscopic surgery, including a suture 1 with a suture needle 11 at the front end, a guide cannula 2, a magnetic suture guide 3, and a magnetic anchor point 12. The suture needle 11 and the magnetic anchor point 12 are both made of magnetic metal. The magnetic anchor point 12 is located at the tail end of the suture 1. The front end of the magnetic suture guide 3 is provided with an electromagnet 31 that attracts the suture needle 11 or the magnetic anchor point 12. The guide cannula 2 is provided with a guide channel 21 that leads from the outside to the suture position inside the body and allows the magnetic suture guide 3 and the suture 1 to pass through. The suture needle 11 is attracted by the electromagnet 31 of the magnetic suture guide 3. The suture 1 is guided through the guide channel 21, and the suture position is sutured by multiple attraction and release. With the help of the magnetic anchor point 12 at the tail end of the suture 1, the suture is assisted and the surgical field is easily organized. This solves the drawbacks of traditional mechanical needle holders for suturing, such as bleeding risk, easy entanglement, and difficulty in accurately controlling the angle and force of the suture needle, thereby optimizing the suturing effect.

[0023] The magnetic thread guide 3 includes a grip rod 32 for hand use. The front end of the grip rod 32 is provided with a simulated finger 33 and a motion simulation mechanism that drives the simulated finger 33 to swing. An electromagnet 31 is provided at the front end of the simulated finger 33. The simulated finger 33 of the magnetic thread guide 3 simulates the swinging motion of the finger 33 when holding the needle, making the suturing method closer to reality and further optimizing the suturing effect and operational flexibility.

[0024] The motion simulation mechanism includes a simulated motor 34 fixed inside the grip rod 32. The front end of the grip rod 32 is provided with a simulated cavity 321. The rear end of the simulated finger 33 is located inside the simulated cavity 321 and is provided with a rotating shaft 331 that rotates with the simulated cavity 321. A driven gear 332 is fixedly provided on the rotating shaft 331. The simulated motor 34 drives an active gear 341 that meshes with the driven gear 332. The simulated motor 34 drives the active gear 341 to rotate, thereby driving the driven gear 332 that meshes with the active gear 341 to rotate, which in turn causes the rotating shaft 331 to rotate, thus realizing the precise swinging of the simulated finger 33.

[0025] The grip rod 32 is equipped with a battery 35 and a conductive slip ring 36. The conductive slip ring 36 is installed on the rotating shaft 331 and forms a power supply cooperation between the battery 35 and the electromagnet 31. The conductive slip ring 36 can provide a continuous and stable power supply to the electromagnet 31 through the battery 35 in the grip rod 32, thereby ensuring the reliability of the electromagnet 31's attraction.

[0026] The rear end of the grip lever 32 is equipped with a button 37 for controlling the on / off of the power supply circuit of the electromagnet 31 and a knob 38 for adjusting the magnetic force of the electromagnet 31. Integrating the button 37 for controlling the on / off of the power supply circuit of the electromagnet 31 and the knob 38 for adjusting the magnetic force of the electromagnet 31 into the rear end of the grip lever 32 makes the operation of medical staff more convenient and precise.

[0027] The surface of electromagnet 31 is covered with an insulating coating. The addition of an insulating coating to the surface of electromagnet 31 meets the medical device specifications for preventing current conduction.

[0028] The surface of the suture needle 11 has fluorescent markers. By adding fluorescent markers to the suture needle 11, the position of the suture needle 11 can be accurately tracked with the help of a fluorescent tracking device. If a suture needle or suture accidentally falls out into the chest cavity, it can be quickly found and retrieved with the help of a magnetic suture guide 3, reducing interference with the operation.

[0029] In addition, a circuit board 39 with a controller is provided inside the grip rod 32. The circuit board 39 is electrically connected to various circuit components and works together under the control of the controller. The battery 35 can be charged through the wireless charging module 30.
