Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tunnel-type minimally invasive lung nodule resection instrument. Background Art

[0002] At present, with the continuous improvement of people's living standards, people's requirements for health are increasing. At the same time, with the advancement of science and technology, the clarity of imaging examinations has been greatly improved. Many malignant lung nodules, represented by early lung cancer, can be detected when the diameter is less than 3-4mm.

[0003] The main treatments for lung nodules / early lung cancer are surgery and ablation. Traditional video-assisted thoracoscopic surgery (VATS) requires the removal of the lung segment or lobe containing the nodule. Even with wedge resection, excessive normal lung tissue may still be removed, leading to loss of lung function. Although the incision of single-port thoracoscopic surgery is only 2-3 cm, deep nodules require the removal of lung segments or even lobes, which has a significant impact on patients with poor lung function reserves (such as the elderly or patients with chronic lung disease). Ablation therapy cannot completely remove the lesions, and it relies on imaging to determine the inactivation effect. The scars formed after ablation may mask signs of recurrence, leading to delayed discovery. In addition, ablation may destroy the tumor structure and increase the risk of metastasis.

[0004] Therefore, there is an urgent need for a tunnel-type minimally invasive lung nodule resection instrument that can provide smaller surgical incisions, less tissue damage, and preserve more healthy lung tissue for patients, while reducing the patient's postoperative recovery time and discomfort, and effectively providing more accurate, convenient, and low-traumatic treatment for patients with smaller diameter lung nodules / early lung cancer.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-Figure 5 The present invention provides a tunnel-type minimally invasive lung nodule resection instrument, comprising a connecting module 4, one end of which is equipped with a rotation adjustment component, and the other end of the connecting module 4 is provided with a resection module 5; the resection module 5 includes a piercing part for piercing the lung tissue and a cutting part for cutting the lung tissue, and the cutting part is transmission-connected to the rotation adjustment component; a power supply part is provided in the connecting module 4, and the power supply part is used to supply power to the piercing part and the cutting part so that the piercing part and the cutting part can stop bleeding on the wound.

[0028] The connecting module 4 is a circular cut outer tube.

[0029] The present invention can provide less trauma and more precise excision through the piercing part and the cutting part, so that the wound can have a shorter recovery time; at the same time, the present invention can more thoroughly and completely remove tumor tissue through the piercing part and the cutting part, effectively reducing the risk of residue, recurrence and metastasis.

[0030] A further optimized solution is that the rotation adjustment assembly includes a first bidirectional rotary switch 1 and a second bidirectional rotary switch 2, the second bidirectional rotary switch 2 is fixedly connected to the end of the connecting module 4, and the first bidirectional rotary switch 1 is arranged at the end of the second bidirectional rotary switch 2 away from the connecting module 4.

[0031] The second bidirectional rotary switch 2 drives the puncture portion to puncture the lung tissue while rotating through the connecting module 4, and then the puncture portion can hook the tissue by rotating the second bidirectional rotary switch 2 in the reverse direction.

[0032] In a further optimized solution, the first two-way rotary switch 1 passes through the second two-way rotary switch 2 and extends into the connecting module 4, so that the first two-way rotary switch 1 and the second two-way rotary switch 2 can rotate separately.

[0033] A further optimized solution is that the insertion portion includes a plurality of support plates fixedly connected to the end of the connection module 4 away from the second two-way rotary switch 2. The end of the support plate away from the connection module 4 is fixedly connected to a longitudinal cutting blade, and the end of the longitudinal cutting blade away from the support plate is provided with a longitudinal cutting edge 6, and the side of the longitudinal cutting blade away from the end of the support plate is provided with a hook tip 7. The second two-way rotary switch 2 is rotated in the direction of the longitudinal cutting edge 6 away from the hook tip 7, so that the longitudinal cutting edge 6 can be rotated and inserted into the lung tissue. When the longitudinal cutting edge 6 reaches the target position, the second two-way rotary switch 2 is rotated in the direction of the hook tip 7, so that the hook tip 7 can effectively hook the tissue; the hook tip 7 can effectively assist in the removal of the specimen.

[0034] Further optimizing the solution, the support plate, the longitudinal cutting blade and the connecting module 4 are integrally formed. Not only can the support plate effectively and stably support the longitudinal cutting edge 6, but also the longitudinal cutting edge 6 and the hook tip 7 can stably perform the piercing work.

[0035] To further optimize the solution, multiple longitudinal cutting blades are evenly spaced, effectively improving the efficiency of penetration.

[0036] According to a further optimized solution, the cutting portion includes a plurality of horizontal cutting blades 8, which are arranged between the plurality of longitudinal cutting blades. The horizontal cutting blades 8 are connected to the first bidirectional rotary switch 1 through a transmission portion.

[0037] The transmission part includes a first gear rotatably connected to the connection module 4, the first gear is engaged with a plurality of second gears, and the second gears are rotatably connected to the connection module 4. The first gear is transmission-connected to the first bidirectional rotary switch 1 via a first transmission shaft.

[0038] The second gear is arranged in a one-to-one correspondence with the horizontal cutting blade 8, and the second gear is transmission-connected to the horizontal cutting blade 8 via a second transmission shaft.

[0039] The first bidirectional rotary switch 1 drives the first gear to rotate through the first transmission shaft, and the first gear synchronously drives multiple second gears to rotate. The second gear drives the horizontal cutting blade 8 through the second transmission shaft, so that the tips of the multiple horizontal cutting blades 8 are close to or away from each other.

[0040] When the tips of the multiple horizontal cutting blades 8 approach and abut each other, the tips of the multiple horizontal cutting blades 8 are at the same center of a circle. Figure 5 Shown is the state after cutting.

[0041] When the tips of the multiple horizontal cutting blades 8 are away from each other, the multiple horizontal cutting blades 8 abut against the opposite side of the multiple support plates. Figure 3 The initial state is shown.

[0042] In a further optimized solution, multiple horizontal cutting blades 8 are arranged at equal intervals, so that the multiple horizontal cutting blades 8 can effectively cut the tissue.

[0043] In a further optimized solution, the power supply unit includes a power supply installed in the connection module 4, the power supply is electrically connected to a power switch 3, and the power switch 3 is embedded in the outer wall of the connection module 4. The power supply can be controlled by the power switch 3.

[0044] In a further optimized solution, the power supply is electrically connected to the longitudinal cutting blade and the horizontal cutting blade 8 through the power switch 3. By turning on the power switch 3, high-frequency current can be passed through the longitudinal cutting blade and the horizontal cutting blade 8 during puncture and cutting, thereby facilitating cutting and hemostasis.

[0045] When used, the present invention can effectively avoid damage to blood vessels and trachea by being used in conjunction with a CT guidance system and a lung nodule positioning system.

[0046] Working process: According to the CT guidance system and the lung nodule positioning system, along the positioning wire, through the body surface, the multiple longitudinal cutting blades at the end of the cutting outer tube are used. Through the second two-way rotary switch 2, the multiple longitudinal cutting blades can be rotated and cut while piercing the predetermined position, and then the second two-way rotary switch 2 is rotated in reverse to make the hook tip 7 hook the tissue; at the same time, by rotating the first two-way rotary switch 1, the multiple horizontal cutting blades 8 are brought close to each other. Through the process of the multiple horizontal cutting blades 8 approaching each other, the horizontal cutting blades 8 can cut the bottom tissue of the lung nodule. After the resection is completed, the specimen is hung at the hook tip 7 and can be taken out at the same time with the connection module 4.

[0047] The present invention adopts an ultra-minimally invasive method to remove lung nodules, which can effectively protect the surrounding healthy tissues.
