Description

Technical Field

[0001] The utility model relates to a lung lobe forceps for laparoscopy, belonging to the technical field of medical equipment. Background Art

[0002] Laparoscopic radical resection of lung cancer and lobectomy are currently common surgical procedures in thoracic surgery. Previously, laparoscopic lobectomy required three to four small incisions in the patient's chest wall to facilitate insertion of various instruments for retraction and separation of the lung lobes and various procedures. However, with technological advancements and the deepening of the concept of minimally invasive surgery, more and more surgeons prefer to use single-port or single-operation port procedures, approximately 2-3 cm in length, to reduce surgical trauma. However, single-port or single-operation port procedures require intraoperative retraction of the lung lobe to expose structures anterior, posterior, and superior to the hilum, such as the pulmonary artery, pulmonary vein, and bronchi, from different directions, enabling surgical separation and division. Clinically, an assistant or the surgeon often needs to insert laparoscopic forceps through a single port or small incision to apply compression and retraction. This is not only ineffective, with inadequate compression and retraction and a tendency to slip, but the laparoscopic forceps themselves further occupy the confined surgical incision space, making the operation more inconvenient and difficult for the surgeon, prolonging the operation time and increasing the risk of surgery.

[0003] Existing pulmonary forceps are widely used because they can precisely cut and clamp lung tissue, reduce surgical time and patient blood loss, and are safe, reliable, and have significant advantages. However, most current pulmonary forceps are oval, triangular, or banana-shaped. Oval pulmonary forceps may not fit tightly enough when clamping irregularly shaped lung tissue, resulting in unstable clamping or tissue damage. Triangular or banana-shaped pulmonary forceps are not flexible enough in certain surgical operations, making it difficult to adapt to changing surgical needs and difficult to operate accurately in a narrow surgical space, especially during complex lung surgeries. Therefore, there is an urgent need for a pulmonary forceps that is more flexible and less likely to cause damage during operation. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to provide a lung lobe clamp which is more flexible in operation and less likely to cause damage due to unstable clamping during the clamping process.

[0005] In order to solve the above technical problems, the utility model provides a laparoscopic lung lobe forceps, which is more in line with mechanical principles when clamping and pulling the lung lobe at various angles, and is more flexible and non-destructive.

[0006] To achieve the above technical objectives and effects, this application is implemented through the following technical solutions:

[0007] A laparoscopic lung lobe forceps comprises a first forceps arm and a second forceps arm, wherein the second forceps arm is hinged in the first forceps arm and both ends extend out of the first forceps arm, and handles are provided on the side walls of the first and second forceps arms that are away from each other, and the front ends of the first and second forceps arms are bent in the same direction to form an arc bend portion 1 and an arc bend portion 2 respectively, and the end of the first arc bend portion away from the first forceps arm is provided with a first forceps head, and the end of the second arc bend portion away from the second forceps arm is provided with a second forceps head, and the first and second forceps heads are identically shaped teardrop-shaped forceps bodies, and both the first and second forceps heads are provided with teardrop-shaped clamping holes; and at least one group of mutually meshing non-damaging teeth are provided on the opposite side walls of the first and second forceps heads.

[0008] Preferably, the arc height of the first arc portion and the second arc portion is between 10 mm and 20 mm.

[0009] Preferably, the ends of the pliers head 1 and the pliers head 2 that are away from the pliers arm 1 and the pliers arm 2 are ends with larger diameters.

[0010] Furthermore, the larger diameter ends of the clamp head 1 and the clamp head 2 are bent in the same direction as the arc-bend portion 1 and the arc-bend portion 2 to form a protrusion.

[0011] Preferably, the size of the head ends of the first and second pliers heads is between 1.4 cm and 2.4 cm.

[0012] Preferably, a buffer assembly is provided between the opposite side walls of the clamp arm 1 and the clamp arm 2 near the end, and the buffer assembly includes a buffer block 1 and a buffer block 2. The buffer block 1 is provided on one side wall of the clamp arm, and the buffer block 2 is provided on the side wall of the clamp arm 2. The buffer block 1 and the buffer block 2 are staggered up and down, and a plurality of buffer teeth are provided on the side wall of the buffer block 2 facing the buffer block 1. The plurality of buffer teeth are evenly spaced from the clamp arm 2 toward the clamp arm 1, and a plurality of buffer grooves engaged with the buffer teeth are provided on the buffer block 1.

[0013] The utility model provides a laparoscopic lung forceps, which has the following advantages:

[0014] 1. The laparoscopic lung forceps of the present invention have a teardrop-shaped head portion, so that the contact area between the head and the clamped object is relatively large. The larger contact area can provide more clamping points, thereby increasing the stability and reliability of clamping.

[0015] 2. Compared to other shaped forceps, the teardrop-shaped head of the laparoscopic lung forceps of this utility model can more evenly distribute stress during the clamping process, reducing stress concentration. This helps reduce the risk of damage to the clamped object and improves clamping stability.

[0016] 3. The laparoscopic lung forceps of the present invention have a teardrop-shaped head that can better adapt to soft and slippery tissues such as lung lobes in complex environments such as laparoscopic surgery. Its design helps to reduce the weakening of the interlocking effect between the head and the tissue, and improve the flexibility and stability of clamping.

[0017] 4. The laparoscopic lung forceps of the present invention, through the arrangement of non-damaging teeth on the forceps head 1 and the forceps head 2, not only improve the anti-slip property of the lung forceps during the clamping process, thereby improving the efficiency of the operation, but also greatly reduce the damage to the lung lobe, thereby improving the safety during the operation.

[0024] Reference Figure 1-Figure 3A laparoscopic lung lobe forceps comprises a forceps arm 1 and a forceps arm 2, wherein the forceps arm 2 is hinged in the forceps arm 1 and both ends extend out of the forceps arm 1, and a handle 3 is integrally formed on the side walls of the forceps arm 1 and the forceps arm 2 that are away from each other at the ends. The front ends of the forceps arm 1 and the forceps arm 2 are bent in the same direction to form an arc bending part 11 and an arc bending part 21 respectively, and the arc bending heights of the arc bending part 11 and the arc bending part 21 are between 10mm and 20mm. A forceps head 12 is integrally formed on the end of the arc bending part 11 away from the forceps arm 1, and a forceps head 22 is integrally formed on the end of the arc bending part 21 away from the forceps arm 2. The forceps head 12 and the forceps head 22 are in the same teardrop shape, and a teardrop-shaped clamping hole 4 is opened on the forceps head 12 and the forceps head 22.

[0025] In a further embodiment, at least one set of mutually meshing non-damaging teeth 5 are integrally formed on the opposite side walls of the forceps head 12 and the forceps head 2 22. The provision of the non-damaging teeth 5 improves the anti-slip property of the lung lobe forceps during the clamping process, improves the efficiency of the operation, and greatly reduces the damage to the lung lobe, thereby improving the safety during the operation.

[0026] In a further embodiment, the ends of the pliers head 12 and the pliers head 2 22 that are away from the pliers arm 1 and the pliers arm 2 2 are the ends with larger diameters, and the size of the head ends of the pliers head 12 and the pliers head 2 22 is between 1.4 cm and 2.4 cm. The ends with larger diameters of the pliers head 12 and the pliers head 2 22 are bent in the same direction as the arc bend 11 and the arc bend 21 to form a protrusion 6. The arrangement of the protrusion 6 ensures that the force point on the lung lobe tissue will not be too large when the pliers head clamps, and it is not easy to be torn.

[0027] Reference Figure 1 and Figure 2 A buffer assembly 7 is installed between the opposite side walls of the clamp arm 1 and the clamp arm 2 near the end.
