Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a curved suction device with segmented graduations. Background Technology

[0002] Thoracoscopic surgery is one of the routine surgeries for the treatment of early-stage lung cancer. During the operation, a suction device is used to remove bleeding, exudate, pus, and contents of thoracic organs, so as to make the surgical field clear and reduce the chance of contamination.

[0003] Conventional curved suction devices, such as the suction device body included in Chinese invention patent application CN116327274A (invention title: a suction device for thoracoscopic surgery, publication date: 2023.06.27), and a thoracoscopic surgical suction device disclosed in Chinese utility model patent CN214966315U (publication date: 2021.12.03), lack graduated markings at the tip of the suction tube. This prevents the operator from directly measuring the distance between lung nodules and key anatomical landmarks during surgery. This deficiency is particularly pronounced in lung nodule localization under single-port thoracoscopic surgery, forcing the surgeon to use a ruler or frequently change instruments. This not only interrupts and prolongs the surgical procedure but also increases the risk of mechanical tissue damage and intraoperative bleeding due to repeated instrument insertion and removal from the single-port channel. While existing straight-tube suction devices have linearly distributed graduated markings, their rigid structure makes them unsuitable for operations on the dorsal and deep regions of the lung in a single-port surgical field, and instrument obstruction affects observation of the surgical field. Its function is limited to basic suction and linear measurement, and it cannot meet the precise measurement needs of complex anatomical structures. In particular, when measuring curved structures such as lung fissures and interlobar fissures, the linearly distributed scale marks are prone to slippage or displacement, resulting in inaccurate measurement data and affecting surgical judgment. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a curved suction device with segmented scales, which integrates precise spatial measurement and efficient suction functions, eliminating the need to change measuring tools during surgery and simplifying the surgical procedure.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A segmented graduated elbow suction device includes a suction device body, which is hollow inside for negative pressure suction. The suction device body has a bending section at its front end and a graduation marking system on its surface. The graduation marking system includes a front graduation area and a rear graduation area. The front graduation area covers the region between the suction head and the bending point, and is a standard ruler graduation. The rear graduation area extends from the bending point towards the end of the suction device body, and the graduation mark value in the rear graduation area is the straight-line distance from the suction head to the corresponding measurement point.

[0007] As a preferred technical solution, the bending angle of the bending portion is 30° to 60°, and the length of the bending portion is 3.0 to 4.0 cm.

[0008] As a preferred technical solution, the bending angle of the bent portion is 45°, and the length of the bent portion is 3.5cm.

[0009] As a preferred technical solution, the range of the scale marking system is 10-15cm, the graduation value of the front scale area is 0.5cm, and the graduation value of the rear scale area is 0.5cm.

[0010] As a preferred technical solution, the suction device body has a suction side hole on its head end side.

[0011] As a preferred technical solution, the rear end of the suction device body is provided with a connection port for connecting a negative pressure source.

[0012] As a preferred technical solution, the rear end of the suction device body is provided with a suction device handle.

[0013] As a preferred technical solution, the suction device handle is provided with finger grooves.

[0014] As a preferred technical solution, the suction device handle is provided with an anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a segmented graduated curved suction device that innovatively integrates precise spatial measurement with efficient suction. The curved section adapts to the three-dimensional operation requirements of single-port surgery. While effectively removing blood and exudate from the surgical field, the segmented graduated marking system enables real-time and accurate positioning of lung nodules and surrounding anatomical structures. Compared to traditional methods, this invention eliminates the need to change measuring tools during surgery, simplifying the surgical procedure. The integrated structural design avoids instrument interference within the single-port channel, and the optimized suction system ensures stable performance during the operation. This significantly improves the operational efficiency and safety of lung nodule resection surgery, providing a more comprehensive instrument solution for thoracoscopic minimally invasive surgery.

[0022] A type of elbow suction device with segmented graduations, such as Figure 1 , Figure 2As shown, the device includes a suction body 1, which is hollow inside for negative pressure suction. The suction body 1 has a bent section 2 at its front end and a scale marking system 3 on its surface. The scale marking system 3 includes a front scale area 31 and a rear scale area 32. The front scale area 31 covers the area between the suction head and the bent end, and is a standard ruler scale. The rear scale area 32 extends from the bent end towards the end of the suction body 1. The scale marking value of the rear scale area 32 is the straight-line distance from the suction head to the corresponding measurement point, such as... Figure 2 As shown, the scale mark "10" indicates that the straight-line distance from the end of the suction device to the mark is 10cm. Refer to scale 8.

[0023] Preferably, the bending angle of the bending portion 2 is 30° to 60°, and the length of the bending portion 2 is 3.0 to 4.0 cm. In a specific embodiment, the bending angle of the bending portion 2 is 45°, and the length of the bending portion 2 is preferably 3.0 cm, 3.5 cm, or 4.0 cm.

[0024] Preferably, the range of the scale marking system 3 is 10-15cm, the graduation value of the front scale area 31 is 0.5cm, and the graduation value of the rear scale area 32 is 0.5cm.

[0025] Preferably, the suction body 1 has a suction side hole 4 on the side of the head end. The addition of the suction side hole 4 allows for the suction of contents through the suction side hole even when the head end is blocked.

[0026] Furthermore, the rear end of the suction device body 1 is provided with a connection port 5 for connecting a negative pressure source, and the rear end of the suction device body 1 is provided with a suction device handle 6 for easy gripping and better operational convenience. Preferably, the suction device handle 6 is provided with finger grooves 7 or with anti-slip texture to provide a better grip and more stable operation.

[0027] The method for locating lung nodules using the curved suction device of this invention is as follows: After obtaining the positioning parameters based on the preoperative CT images, the surgeon uses a specially designed scale marking system on the curved suction device to measure the relative distance between the lung nodule positioning point and the key anatomical structures in the thoracic cavity in real time, thereby achieving precise intraoperative positioning and ensuring accurate resection of the target lung nodule.

[0028] This invention addresses the anatomical characteristics of large curvature variations on the surface of organs within the thoracic cavity. The front graduation area 31 maintains a standard straight-line graduation to ensure intuitive operation; the rear graduation area 32 uses straight-line distance markings, so that the graduation readings truly reflect the spatial straight-line distance between the suction tip and the measurement point. This retains the convenience of conventional measurements while overcoming the measurement deviation problem caused by curved anatomical structures, achieving precise spatial positioning throughout the entire surgical field.

[0029] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
