Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a duckbill-shaped thoracic suction device. Background Technology

[0002] In thoracic surgery, radical resection of lung cancer is one of the most effective treatments for lung cancer, and systematic lymph node dissection is a crucial step in this procedure. The quality of the dissection directly affects the accuracy of postoperative staging and long-term survival rate. In thoracoscopic-assisted or fully thoracoscopic lung cancer surgery, medical staff typically need to use a variety of instruments to expose, dissect, and dissect the lymph nodes.

[0003] Suction devices are one of the most basic auxiliary instruments in thoracic surgery. For example, the medical thoracic suction device designed by Longnan Hospital in Rang District, Daqing City, Heilongjiang Province, is mainly used to remove blood, irrigation fluid and smoke generated by electrocautery from the surgical field in order to maintain a clear surgical field.

[0004] Currently used thoracic suction devices in clinical practice typically have a rounded metal tubular end. However, when this end contacts the lymph node surface, the small contact area and insufficient tangential friction make it prone to slippage when dislodging lymph nodes. This makes it difficult to effectively fix and position mobile lymph nodes, reducing dissection efficiency and increasing the risk of accidental injury to surrounding important blood vessels and nerves. Therefore, it is necessary to propose a duckbill-shaped thoracic suction device to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a duckbill-shaped thoracic suction device. Through the duckbill-shaped structural design of the suction head, medical staff can perform multiple operations such as blocking, fixing, and suction with one hand, thereby improving the efficiency of lymph node dissection, reducing the risk of intraoperative complications, and enhancing the operating experience of medical staff.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a duckbill-shaped thoracic aspirator, comprising an aspiration tube, a connecting tube detachably connected to one end of the aspiration tube, a duckbill-shaped aspiration head fixedly connected to the end of the connecting tube away from the aspiration tube, and an elliptical aspiration port opened at the end of the aspiration head away from the connecting tube.

[0007] The suction tube is equipped with a gripping component for medical staff to hold the suction tube;

[0008] A negative pressure adsorption component is provided at the end of the suction tube away from the connecting tube.

[0009] The technical principle of the above solution is as follows:

[0010] Medical staff hold the suction device and insert the suction head, connecting tube, and suction tube into the target surgical area. They then activate the negative pressure suction device to adsorb liquids, gases, and microparticles at the designated location. During the adsorption process, the duckbill-shaped suction head is used to deflect and fix the lymph nodes to prevent them from sliding, and only liquids, gases, and microparticles at the designated location are adsorbed.

[0011] The above approach has the following beneficial effects:

[0012] 1. Existing thoracic aspirators typically have a rounded end. When the rounded end contacts the surface of a lymph node, the contact area is small and the tangential friction is insufficient, making it easy for the aspirator to slip off when dislodging the lymph node. In contrast to the prior art, this invention designs the aspirator head in a duckbill shape, which can effectively increase the contact area between the aspirator head and the lymph node, thereby effectively dislodging and controlling the lymph node and reducing the risk of accidental damage to blood vessels and nerves.

[0013] 2. Compared to the circular structure, the duckbill-shaped structure allows medical staff to better judge and control the rotation direction and position of the suction head, thereby better controlling and adjusting the suction head, and thus better blocking and controlling the lymph nodes during the operation, further reducing the risk of accidental damage to blood vessels and nerves.

[0014] 3. The present invention integrates multiple functions such as blocking, fixing and suction through the design of the duckbill-shaped suction head, so that medical staff do not need to use additional blocking instruments, which effectively reduces the difficulty of operation and eliminates the need for frequent instrument changes, thereby improving surgical efficiency.

[0015] Furthermore, the diameter of the connecting tube is equal to the diameter of the suction tube, the width of the suction port is smaller than the diameter of the connecting tube, and the length of the suction port is greater than the diameter of the connecting tube.

[0016] Beneficial effects: This structural design allows the flat working surface of the suction head along its length to obtain a larger effective blocking area, enabling it to cover a wider contact range when blocking lymph nodes. At the same time, the lateral dimension of the suction head does not exceed the diameter of the connecting tube, preventing unavoidable space occupation and providing medical staff with a wider field of vision.

[0017] Furthermore, the outer walls of the suction head are all engraved with a grid pattern.

[0018] Beneficial effects: The grid-like texture increases the surface friction of the suction head, thereby better blocking and controlling lymph nodes.

[0019] Furthermore, the end of the suction head furthest from the connecting tube has a blunt, rounded arc structure.

[0020] Beneficial effects: This structural design makes the suction port smoother, which can effectively reduce the risk of scratching patients.

[0021] Furthermore, the length of the suction head increases in the direction away from the connecting tube.

[0022] Beneficial effects: This design can effectively increase the adsorption range of the suction head and improve the suction effect.

[0023] Furthermore, several side suction holes are opened on both sides of the suction head in the width direction.

[0024] Beneficial effects: The side suction port effectively expands the spatial coverage of the suction device, ensuring that the entire operating area always maintains a clear surgical field environment.

[0025] Furthermore, the gripping component includes a handle that is fixedly fitted onto the suction tube.

[0026] Beneficial effects: The handle can effectively improve the ease with which medical staff can hold the suction tube, thereby facilitating better surgical procedures.

[0027] Furthermore, the grip surface has several anti-slip grooves.

[0028] Beneficial effects: The anti-slip grooves can increase the friction between the hands of medical staff and the handle, thereby improving the stability of holding the instrument.

[0029] Furthermore, the negative pressure adsorption assembly includes a controller and a negative pressure pump connected to the suction tube, the controller being used to control the operation of the negative pressure pump.

[0030] Beneficial effects: Medical staff can automatically control the operation of the negative pressure pump through the controller and adjust the operating power of the negative pressure pump, which improves the overall intelligence level of the device.

[0031] Furthermore, the suction head is made of medical-grade stainless steel.

[0032] Beneficial effects: Stainless steel has excellent mechanical strength and corrosion resistance, which can ensure the mechanical requirements of blocking and fixation operations, while adapting to the humid environment of surgery. Attached Figure Description

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the method or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description illustrates the specific implementation method:

[0042] Example 1:

[0043] like Figure 1 As shown, a duckbill-shaped thoracic suction device includes a suction tube 1. One end of the suction tube 1 is detachably connected to a connecting tube 3 via a slot. The end of the connecting tube 3 away from the suction tube 1 is integrally formed and connected to a duckbill-shaped suction head 4. The end of the suction head 4 away from the connecting tube 3 has an elliptical suction port 6.

[0044] like Figure 1 and Figure 3 As shown, the diameter of the connecting tube 3 is equal to the diameter of the suction tube 1, the width of the suction port 6 is smaller than the diameter of the connecting tube 3, and the length of the suction port 6 is greater than the diameter of the connecting tube 3.

[0045] like Figure 1and Figure 3 As shown, the length of the suction head 4 increases in the direction away from the connecting tube 3, so that the flat working surface of the suction head 4 in the length direction can obtain a larger effective blocking area, and can cover a larger contact range when blocking lymph nodes. At the same time, the lateral dimension of the suction head 4 does not exceed the diameter of the connecting tube 3, which can prevent unavoidable space occupation and provide medical staff with more field of vision.

[0046] The suction head 4 is made of medical-grade stainless steel. Stainless steel has excellent mechanical strength and corrosion resistance, which can ensure the mechanical requirements of blocking and fixation operations, while also being suitable for the humid environment of surgery.

[0047] The end of the suction head 4 away from the connecting tube 3 is a blunt arc structure, which makes the surface of the suction port 6 smoother and can effectively reduce the risk of scratching the patient.

[0048] like Figure 1 and Figure 2 As shown, the suction tube 1 is equipped with a gripping assembly for medical personnel to hold the suction tube 1. The gripping assembly includes a handle 2 that is bolted to the suction tube 1. The surface of the handle 2 has several anti-slip grooves, which can increase the friction between the medical personnel's hand and the handle 2, thereby improving the stability of the instrument.

[0049] like Figure 4 As shown, a negative pressure adsorption assembly is provided at the end of the suction tube 1 away from the connecting tube 3. The negative pressure adsorption assembly includes a controller and a negative pressure pump 5 connected to the suction tube 1. The controller is used to control the operation of the negative pressure pump 5.

[0050] Specifically, medical staff hold the handle 2 with one hand and insert the suction head 4, connecting tube 3, and suction tube 1 into the target surgical area. They then activate the negative pressure pump 5 via the controller. The negative pressure pump 5 uses the suction head 4, connecting tube 3, and suction tube 1 to absorb liquids, gases, and small particles from the patient's body. During this process, medical staff can use the duckbill-shaped suction head 4 to press the lymph nodes to one side, thereby blocking and fixing the lymph nodes, preventing them from being absorbed, and avoiding unnecessary damage to blood vessels and nerves.

[0051] The suction head 4 has several side suction holes 7 on both sides in the width direction. During the suction process, blood may seep out or smoke may diffuse around the lymph nodes due to the pressure of the suction head 4. The side suction holes 7 face the two sides of the operating area, which can effectively absorb the seeping blood and diffuse smoke, thereby expanding the spatial coverage of the suction effect and keeping the entire operating area a clear surgical field environment.

[0052] Existing thoracic aspirators typically have a rounded metal tubular end. When this end contacts the lymph node surface, it is difficult to effectively fix and position the mobile lymph node, resulting in reduced cleaning efficiency and increased risk of injury to surrounding important blood vessels and nerves. In contrast, this embodiment designs the suction head 4 in a duckbill shape, effectively increasing the contact area between the suction head 4 and the lymph node. Furthermore, compared to a circular structure, the duckbill shape allows medical personnel to better judge and control the rotation direction and position of the suction head 4, thereby better controlling and adjusting it, effectively deflecting and controlling the lymph node, and reducing the risk of injury to blood vessels and nerves.

[0053] Furthermore, this embodiment integrates multiple functions such as blocking, fixation, and suction through the design of the duckbill-shaped suction head 4. This eliminates the need for medical staff to use additional blocking instruments, allows for one-handed operation, and eliminates the need for frequent instrument changes, effectively reducing the difficulty of the operation and improving the efficiency of the surgery.

[0054] Example 2:

[0055] Unlike the embodiments described above, as Figure 3 As shown, the outer wall of the suction head 4 is engraved with a grid pattern. The grid pattern can increase the surface friction of the suction head 4, thereby better blocking and controlling the lymph nodes.

[0056] Example 3:

[0057] Unlike the embodiments described above, as Figure 1 and Figure 4 As shown, medical staff can adjust the engagement angle between the suction tube 1 and the connecting tube 3. Figure 1 The suction head 4 is in a horizontal position. Figure 4 The suction head 4 is in a vertical position, and the angle of the suction head 4 can be adjusted to meet different surgical needs.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
