Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a thoracoscopic minimally invasive suction device. Background Technology

[0002] With the rise of thoracoscopic surgery, this complex intrathoracic surgery, performed through tiny incisions in the chest wall using high-tech imaging techniques and precision surgical instruments, has rapidly become the mainstream trend in thoracic surgery due to its significant advantages such as minimal trauma, rapid recovery, and reduced pain. Against this backdrop, the thoracoscopic minimally invasive suction device has emerged. As an important component of surgical instruments, its development has undergone continuous evolution from simple to complex, and from single to multiple functions.

[0003] Current thoracoscopic minimally invasive surgery still uses the same suction device, which can easily lead to over-inflation of the patient's lungs, affecting the surgical field of view and hindering postoperative pleural lavage. Therefore, there is an urgent need to develop a new thoracoscopic minimally invasive suction device to overcome the shortcomings in current applications. Utility Model Content

[0004] The purpose of this invention is to provide a thoracoscopic minimally invasive suction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thoracoscopic minimally invasive suction device, comprising a thoracoscopic suction device, and further comprising:

[0007] A suction tube, one end of which is connected to one end of the thoracoscopic suction device, and a side hole is provided on the suction tube, which is located near the end of the thoracoscopic suction device;

[0008] And a T-shaped flexible tube, one end of which is connected to the other end of the thoracoscopic suction device.

[0009] As a further embodiment of this utility model: the proximal connection end one on the suction tube is connected to the proximal connection end two on the thoracoscopic suction device;

[0010] The distal end of the thoracoscopic suction device is connected to the T-shaped hose connection end of the T-shaped hose.

[0011] As a further embodiment of this utility model, it also includes a second side hole, which is formed on the T-shaped flexible tube and disposed away from the connection end of the T-shaped flexible tube.

[0012] As a further embodiment of this utility model: the T-shaped hose is in the form of an 18-gauge T-shaped tube and is made of latex.

[0013] As a further aspect of this utility model: the length of the No. 18 T-tube is 1.5cm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The side hole reserved in the ordinary suction tube covers its size and is used in conjunction with the minimally invasive incision to control the suction of the thoracoscopic suction device. This can prevent the lung from over-inflation during single-lung ventilation, which would affect the surgical field of vision. It can also increase the negative pressure in the pleural cavity to avoid atelectasis during double-lung ventilation. The minimally invasive incision can be used to modify the thoracoscopic suction device to increase the negative pressure in the pleural cavity to assist in postoperative pleural irrigation, prevent leakage of irrigation fluid, and ensure a sterile environment for the operation as much as possible.

[0016] 2. During suturing, a section of 18-gauge T-tube (approximately 1.5cm) at the distal end of the modified thoracoscopic suction device can be used to prevent the suture needle from retracting and to prevent unnecessary tissue from being sutured. The angle of the suture needle can be quickly adjusted within the pleural cavity, facilitating continuous suturing and avoiding unnecessary collateral damage caused by repeated entry and exit of the suture needle into the pleural cavity.

[0017] 3. The 18-gauge T-tube (approximately 1.5cm) at the distal end of the modified thoracoscopic suction device can be used in conjunction with the electrocautery hook to dissect the tissues that need to be separated, reducing or even avoiding damage to the tissues by the metal suction device, and preventing unnecessary, irreversible, or even fatal secondary injuries.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1-3 The present invention provides a thoracoscopic minimally invasive suction device, including a thoracoscopic suction device 4, and further comprising:

[0025] A suction tube 1, one end of which is connected to one end of the thoracoscopic suction device 4, and a side hole 2 is provided on the suction tube 1, which is located near the end of the thoracoscopic suction device 4.

[0026] And a T-shaped flexible tube 5, one end of which is connected to the other end of the thoracoscopic suction device 4.

[0027] In one embodiment of this utility model, please refer to Figures 1-3 The proximal connection end 3 on the suction tube 1 is connected to the proximal connection end 8 on the thoracoscopic suction device 4.

[0028] The distal connection end 7 of the thoracoscopic suction device 4 is connected to the T-shaped hose 5 connection end of the T-shaped hose 5.

[0029] Please see Figures 1-3 It also includes: a second side hole 6, which is formed on the T-shaped flexible tube 5 and is located away from the connection end of the T-shaped flexible tube 5; wherein, the second side hole 6 is close to the far end of the T-shaped flexible tube 5 (i.e., the end away from the connection end of the T-shaped flexible tube 5 and about 1mm away from the far end);

[0030] The second side hole 6 prevents the single hole from being sucked into the lung tissue, thus failing to achieve the function of attracting blood and smoke generated when the electric hook is used.

[0031] Please see Figures 1-3 The T-shaped hose 5 is in the form of an 18-gauge T-shaped hose and is made of latex.

[0032] The T-shaped flexible tube 5 is flexible and can safely assist in blunt dissection of blood vessels, trachea and lymph nodes, and avoid damage to tissues;

[0033] In addition, during the suturing process, the direction of the suture needle can be adjusted using the No. 18 T tube to avoid repeated entry and exit of the suture needle into the thoracic cavity, which could cause unnecessary collateral damage.

[0034] The length of the No. 18 T-tube is 1.5cm.

[0035] By connecting the proximal end of a conventional thoracoscopic suction device 4 to a regular suction tube 1 with a side hole 2 at the proximal end, and attaching a T-shaped flexible tube 5 to the distal end, the T-shaped flexible tube 5 is an 18-gauge T tube (approximately 1.5 cm long, with a counter-current side hole 6 at the distal end).

[0036] Because the incision in minimally invasive thoracoscopic surgery is extremely small, a closed space can be formed at any time, which may lead to uncontrollable situations during the surgery. Therefore, the suction force of the thoracoscopic suction device 4 can be controlled by adjusting the opening and closing state of the side hole 2 of the ordinary suction tube 1 that covers the proximal end and has a side hole 2.

[0037] During suction, the modified thoracoscopic suction device 4, in conjunction with the minimally invasive incision, controls the suction force of the thoracoscopic suction device 4, adjusts lung re-expansion, and at the same time prevents postoperative atelectasis and assists in pleural irrigation.

[0038] During tissue dissection, on the one hand, the T-shaped flexible tube 5, which is a section of an 18-gauge T-tube (approximately 1.5cm long, with a counter-flush side hole 6 at the distal end) of the modified thoracoscopic suction device 4, can safely assist in the dissection of blunt vessels, trachea, and lymph nodes. On the other hand, it can be used in conjunction with the electrocautery hook to dissect the lung tissue that needs to be separated, avoiding fatal collateral damage. The T-shaped flexible tube 5 acts like a dissector, mainly utilizing the flexibility of the modified thoracoscopic suction device 4 to avoid unnecessary and fatal damage leading to massive bleeding.

[0039] Therefore, the modified thoracoscopic suction device 4, in addition to the functions of a regular suction device, also allows the surgeon to easily control the suction pressure, thereby controlling the expansion and collapse of lung tissue. Thus, a low suction force can allow the lung tissue to collapse fully, exposing a good surgical field; a high suction force can allow the lung to expand, preventing postoperative atelectasis.

[0040] In addition, when suturing, after finishing a stitch, it can be sewn onto a section of T-shaped soft tube 5, i.e., a No. 18 T tube, about 1.5cm long, to bring out the suture needle. Inside the chest cavity, a section of No. 18 T tube can be used to adjust the direction of the suture needle, avoiding repeated removal of the suture needle and aggravating the collateral damage to the surrounding tissues.

[0041] In summary, the side hole 2 reserved in the ordinary suction tube 1 covers its size and, in conjunction with the minimally invasive incision, controls the suction force of the thoracoscopic suction device 4. This can prevent over-inflation of the lung during single-lung ventilation, which would affect the surgical field of vision. It can also increase the negative pressure in the pleural cavity to prevent atelectasis during double-lung ventilation. The modified thoracoscopic suction device 4 used in the minimally invasive incision can increase the negative pressure in the pleural cavity to assist in postoperative pleural lavage, prevent leakage of lavage fluid, and ensure a sterile surgical environment to the greatest extent possible.

[0042] During suturing, a section of 18-gauge T-tube (approximately 1.5cm) at the distal end of the modified thoracoscopic suction device 4 can be used to prevent the retraction of the suture needle and to prevent unnecessary tissue suturing. The angle of the suture needle can be quickly adjusted within the pleural cavity, facilitating continuous suturing and avoiding unnecessary collateral damage caused by repeated entry and exit of the suture needle into the pleural cavity.

[0043] The 18-gauge T-tube (approximately 1.5cm) at the distal end of the modified thoracoscopic suction device 4 can be used in conjunction with the electrocautery hook to separate the tissues required for dissection, reducing or even avoiding damage to the tissues caused by the metal suction device, thus preventing unnecessary, irreversible, or even fatal collateral damage.
