Description

Technical Field

[0001] The present invention relates to the technical field of circular internal cutting closure devices, and in particular to a circular internal cutting closure device for subpleural ground glass nodules of the lungs and an operation method thereof. Background Art

[0002] Ground-glass nodules are a term used to describe a type of nodular shadow in thin-layer CT images of the lungs. This indicates that there are focal nodular density-enhanced shadows in the lungs, with clear or unclear shadow boundaries. Moreover, the density of the lesions is not enough to cover up the deformed bronchial vascular bundles. This typical sign is called a ground-glass density nodule, which is like a small piece of ground glass covering the lung tissue.

[0003] Among them, the "CT-guided percutaneous puncture of lung nodules cutter" disclosed in the application number "CN116019500B" is also an increasingly mature technology, which "includes an outer sheath puncture guide needle and a net bag-shaped electromagnetic cutting system, a hollow sleeve is arranged in the outer sheath puncture guide needle, and a net bag-shaped electromagnetic cutting system is arranged in the space between the outer sheath puncture guide needle and the hollow sleeve, and the main body of the net bag-shaped electromagnetic cutting system is made of a tubular polymer shape memory material, and at the same time, the position of the tubular shape toward the tip of the outer sheath puncture guide needle is integrally formed into two net bags; the invention ensures the comfort of patients, the safety of doctors' operation, and the effectiveness of pathological sampling, so that medical personnel engaged in puncture biopsy can use this lung nodule puncture cutter, which is simple and easy to operate, safe and accurate in positioning, and significantly improves the success rate of pathological diagnosis of lung nodules, while reducing the economic burden of patients and improving their comfort; it is also conducive to promoting and popularizing percutaneous cutting biopsy of lung nodules under CT guidance.

[0004] However, the above-mentioned CT-guided percutaneous puncture lung nodule cutter design has the following disadvantages: the lung nodule cutter cannot clamp at a designated position of the lung, which may easily cause the laser cutter to remove healthy lungs during cutting, and it is impossible to clamp and fix the lung nodule site in advance for cutting. At the same time, when the cut lung nodule tissue is removed from the lung, it is not convenient to grasp and remove it, which may easily cause it to fall off.

[0005] Therefore, it is necessary to provide a circular inner cutting closure device for subpleural ground glass nodules of the lung and an operation method thereof to solve the above problems. Summary of the invention

[0010] Preferably, the cutting mechanism includes a fixed seat fixedly connected to the inside of the circular cutting inner cylinder. One side of the fixed seat is fixedly connected with an electric telescopic rod. The telescopic end of the electric telescopic rod is fixedly connected with a mounting seat. One side of the mounting seat is fixedly connected with two longitudinal slide rails and a transverse slide rail. A sliding seat is slidably connected to the side of the transverse slide rail and the two longitudinal slide rails in a limited manner. Gear racks are fixedly installed on the side of the transverse slide rail and the two longitudinal slide rails. A small gear is meshed with one side of the gear rack.

[0012] Preferably, a method for operating a circular internal cutting and closing device for subpleural ground-glass nodules in the lung includes the following steps:

[0013] Step 1: Preoperative preparation. The patient needs to undergo a series of examinations, including chest CT examination, blood routine examination, etc., to evaluate the physical condition and the nature of the lung nodule.

[0014] According to the specific situation of the patient, the doctor will choose a suitable anesthesia method, usually general anesthesia.

Sometimes, open-chest surgery may also be used, but it has basically been abandoned clinically at present.

[0017] According to the size of the pulmonary nodule, the doctor will select an appropriate surgical method to remove the lesion. For pulmonary nodules on the edge of the lung, circular internal cutting is performed through a cutting mechanism.

[0020] The present invention provides a circular internal cutting stapler for subpleural ground-glass nodules in the lung and its operation method:

[0021] 1. When performing laser cutting of pulmonary nodules, in order to facilitate accurate clamping of the position of small pulmonary nodules for precise laser cutting, it is necessary to clamp and fix the lungs at the pulmonary nodule site. The rotation of a small motor drives the rotation of a small gear, and it slides back and forth on the rack, facilitating the sliding adjustment of the sliding seats on the transverse slide rail and the two longitudinal slide rails to approach or move away, so as to clamp the nodule position area of the lungs. The rotation of a first small motor drives the rotation of a first small gear, so that the first small gear meshes and drives the adjustment of the fixing frame during rotation, and the rotation of a second small motor on the fixing frame drives the cutting jaws to clamp the nodule part to be cut. Cutting is performed through the set laser cutter to avoid resection of healthy lung tissue.

[0022] 2. When pulling out the cut pulmonary nodule part, the pulling of the pulling rope drives the sliding of the slider on the guide rod. During the sliding process of the slider, the pulling rubber rod on the side is driven, so that the pulling rubber rod pulls the gripper to tightly hold and pull out the cut pulmonary nodule part.

[0044] Such as Figures 1 - 12As shown in the figure, a circular internal cutting and closing device for subpleural ground-glass nodules in the lungs proposed by the present invention includes a control grip 1. A control mechanism 2 is provided on one side of the control grip 1. One end of the control grip 1 is fixedly connected to a fixed shell 101. A data processing mechanism 3 is fixedly connected to one side of the fixed shell 101. A fixed long cylinder 102 is fixedly connected to one side of the control grip 1. One end of the fixed long cylinder 102 is provided with a circular cutting outer cylinder 103. A number of circular cutting inner cylinders 1041 are fixedly installed inside the circular cutting outer cylinder 103. A cutting mechanism 4 is provided inside each circular cutting inner cylinder 1041. A pulling mechanism 5 is provided inside the circular cutting outer cylinder 103. The opening of the circular cutting outer cylinder 103 is provided with a cover plate 6, and the cover plate 6 is provided with a number of slotted holes 104.

[0045] The control mechanism 2 includes a Z-shaped engaging groove 201 opened at the top of the control grip 1. A engaging block 202 is inserted inside the Z-shaped engaging groove 201. A sleeve 203 is provided inside the control grip 1. An insertion rod 204 is inserted inside the sleeve 203. A return spring 205 is sleeved outside the insertion rod 204. One end of the return spring 205 is fixedly connected to the top end of the insertion rod 204. The other end of the return spring 205 is fixedly connected to one side of the sleeve 203. One side of the sleeve 203 is movably connected to a pulling member 207. One end of the pulling member 207 is movably connected to one side of the bottom of the control grip 1. One end of the insertion rod 204 is fixedly connected to a pulling rope 206. The bottom end of the engaging block 202 is fixedly connected to the pulling rope 206 inside the control grip 1.

[0046] During specific use, after a lung operation, it is necessary to pull out the cut lung nodules. When medical staff are operating, they control the pulling mechanism 5 by manipulating the pulling rope 206 to pull out the cut lung nodules. By manually pressing the pulling member 207, when the pulling member 207 is pressed, it drives the sleeve 203 to move, so that the sleeve 203 pushes the return spring 205. Under the elastic action of the return spring 205, the insertion rod 204 is pushed, so that one end of the pulling mechanism 5 grabs the cut lung nodules. Then, by adjusting the engaging block 202 inside the Z-shaped engaging groove 201, the engaging block 202 pulls and fixes the pulling rope 206, preventing the pulling rope 206 from moving and causing the cut lung nodules at one end of the pulling mechanism 5 to fall off. At the same time, it is convenient to drag the circular internal cutting and closing device out of the patient's body.

[0047] The data processing mechanism 3 includes a force-sensitive sensor 301 installed inside the fixed long cylinder 102. A displacement sensor 302 is provided on one side of the force-sensitive sensor 301. A wireless signal receiving module 303 is fixedly connected to the top of the fixed shell 101. A wireless signal transmitting module 304 is provided on one side of the wireless signal receiving module 303. A data analysis module 305 is provided on one side of the wireless signal transmitting module 304.

[0048] During specific use, when removing lung nodules, after the lung nodules are excised by laser using the force-sensitive sensor 301 provided, the pulling force on the lung nodules is monitored. When the pulling mechanism 5 performs laser cutting on the lung nodules, the displacement sensor 302 provided monitors the moving distance of the displacement, so as to facilitate timely feedback of the intraoperative situation to the doctor for understanding. Through the cooperation of the wireless signal receiving module 303 and the wireless signal transmitting module 304 provided, it is convenient to transmit or receive signals for monitoring the situation of lung nodule surgery. Through the data analysis module 305 provided, the data of lung nodule cutting is analyzed, processed, and converted for transmission.

[0049] The cutting mechanism 4 includes a fixed seat 401 fixedly connected to the inside of the circular cutting inner cylinder 1041. One side of the fixed seat 401 is fixedly connected to an electric telescopic rod 402. The telescopic end of the electric telescopic rod 402 is fixedly connected to a mounting seat 403. One side of the mounting seat 403 is fixedly connected to two longitudinal slide rails 404 and a transverse slide rail 405. A sliding seat 406 is slidably connected to the limit on one side of the transverse slide rail 405 and the two longitudinal slide rails 404. Gear racks 407 are fixedly installed on one side of the transverse slide rail 405 and the two longitudinal slide rails 404. A small gear 408 is meshed with one side of the gear rack 407. One side of the small gear 408 is fixedly connected to a small motor 409. The side of the small motor 409 is fixedly connected to a device frame 4010. The top of the small motor 409 is fixedly connected to a first small motor 4011. The transmission end of the first small motor 4011 is fixedly connected to a first small gear 4012. The first small gear 4012 is meshed with the outside of a first arc-shaped tooth 4013. The top of the first arc-shaped tooth 4013 is fixedly connected to a fixed frame 4014. The top of the fixed frame 4014 is fixedly connected to a second small motor 4015. One end of the second small motor 4015 is fixedly connected to a second small gear 4016. The second small gear 4016 is meshed with the outside of a second arc-shaped tooth 4017. One side of the second arc-shaped tooth 4017 is fixedly connected to a cutting clamp 4018. A laser cutter 4019 is fixedly connected to one side of one of the cutting clamps 4018.

[0050] During specific use, when performing laser cutting of pulmonary nodules, in order to facilitate accurate clamping of the position of the pulmonary nodules for precise laser cutting, it is necessary to clamp and fix the lungs at the nodule site. The telescopic movement of the electric telescopic rod 402 on one side of the fixed seat 401 facilitates pushing the mounting seat 403 to extend into the slot hole 104 to approach the part of the lungs with nodules. Then, the rotation of the small motor 409 on the mounting seat 403 drives the small gear 408 to rotate, and it slides back and forth on the rack 407, facilitating the sliding adjustment of the sliding seats 406 on the transverse slide rail 405 and the two longitudinal slide rails 404 to approach or move away, so as to clamp the nodule position area of the lungs. The rotation of the first small motor 4011 drives the first small gear 4012 to rotate, so that the first small gear 4012 meshes and drives the fixing frame 4014 to adjust during rotation. At the same time, the rotation of the second small motor 4015 on the fixing frame 4014 drives the cutting gripper 4018 to clamp the nodule part to be cut, and the laser cutter 4019 is used for cutting.

[0051] The pulling mechanism 5 includes a pulling cylinder 501 arranged in the middle of the circular cutting outer cylinder 103. One side of the pulling cylinder 501 is penetrated by a pulling rope 206. One end of the pulling rope 206 is fixedly connected to a pulling slider 503. The slider 503 is inserted and connected to a guide rod 504 fixedly connected to one side of the pulling cylinder 501. The side of the slider 503 is movably connected to a pulling rubber rod 505. One end of the pulling rubber rod 505 is movably connected to a gripper 502.

[0052] During specific use, when pulling out the cut pulmonary nodule part, the pulling of the set pulling rope 206 drives the slider 503 on the guide rod 504 to slide. During the sliding of the slider 503, the pulling rubber rod 505 on the side is driven, so that the pulling rubber rod 505 pulls the gripper 502 to tightly hold and pull out the cut pulmonary nodule part.

[0053] A method for operating a circular internal cutting and closing device for subpleural ground-glass nodules in the lungs includes the following steps:

[0054] Step 1: Preoperative preparation. The patient needs to undergo a series of examinations, including chest CT examination, blood routine examination, etc., to evaluate the physical condition and the nature of the pulmonary nodules.

[0055] According to the specific situation of the patient, the doctor will choose a suitable anesthesia method, usually general anesthesia.

[0056] Step 2: Surgical procedure

[0057] After the anesthetic effect is satisfactory, the doctor will make a small incision on the surface of the patient's chest skin, and then insert a thoracoscope into the chest cavity to observe the location and size of the lung nodules. Sometimes, open-chest surgery may also be used, but it has basically been abandoned clinically at present;

[0058] According to the size of the lung nodules, the doctor will choose an appropriate surgical method to remove the lesion. For the lung nodules on the lung margin, circular internal cutting is performed through the cutting mechanism 4. If the lesion occurs in a deeper position, close to the root or the nodule is relatively large, the entire lung lobe may be removed. During the resection process, the data processing mechanism 3 is used to monitor the depth or force of the cutting mechanism 4 and feedback it to the medical staff to master the cutting situation;

[0059] After the resection, the traction mechanism 5 is used to drag out the lung nodule tissue. After completion, the doctor will perform lymph node dissection to evaluate whether the nodule has metastasized.

8. A method for operating a circular internal cutting and closing device for ground glass nodules under the pleura of the lung, comprising the circular internal cutting and closing device for ground glass nodules under the pleura of the lung described in 1-7 above, characterized in that: The steps include: Step 1: Preoperative preparation: the patient needs to undergo a series of examinations, including chest CT scan, blood routine test, etc., to assess the physical condition and the nature of the lung nodules; Depending on the patient's specific condition, the doctor will choose the appropriate anesthesia method, usually general anesthesia. Step 2: Surgical Procedure After the anesthesia effect is satisfactory, the doctor will make a small incision on the surface of the patient's chest skin, and then insert a thoracoscope into the chest cavity to observe the location and size of the lung nodules. Sometimes, thoracotomy may be used, but it has been basically abandoned in clinical practice. According to the size of the lung nodule, the doctor will choose an appropriate surgical method to remove the lesion. The lung nodules at the edge of the lung will be cut in a circular manner by the cutting mechanism (4). If the lesion is located deep, close to the root or the nodule is relatively large, the entire lung lobe may be removed. During the removal process, the depth or strength of the cutting mechanism (4) is monitored by the data processing mechanism (3) and fed back to the medical staff to understand the cutting situation. After the resection, the pulmonary nodule tissue is pulled out by the provided pulling mechanism (5). After completion, the doctor will perform lymph node dissection to assess whether the nodule has metastasized.
