Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a laparoscopic surgical suction device with anti-slip, bendable and suction-adjustable functions. Background Technology

[0002] In modern surgical medicine, laparoscopic surgery is widely used due to its advantages such as minimal trauma and rapid recovery. During laparoscopic surgery, the suction device plays an indispensable role as an important auxiliary instrument: it is mainly used to remove blood and tissue fluid that seeps out during the operation, ensuring that the surgical area is clearly visible, and it also has the function of assisting in picking, pushing and separating tissues.

[0003] See Figure 1 Traditional laparoscopic aspirators are long, straight tubes. The rear end of the aspirator tube 10 is a negative pressure connector 101 for connecting to a negative pressure drive device. The aspirator tube also has a button 102 for controlling the suction switch. Traditional laparoscopic aspirators have revealed several significant drawbacks in practical applications: First, the tip of the aspirator tube is usually smooth. When using the aspirator tube to assist in lifting and pushing tissue during surgery, the tip is prone to slippage, affecting not only the precision of the surgery but also increasing the time and difficulty of the procedure. Second, the middle and lower sections of the aspirator tube are mostly fixed and straight, which greatly limits its operation when dealing with deep tissues. Because the aspirator tube cannot be flexibly bent to adapt to different angles and positions, it is difficult to effectively aspirate exudate from multiple angles and pull to expose designated tissues, thus limiting the surgical field of view and ease of operation. Third, most traditional aspirators lack a device for precisely controlling suction. Figure 1 In traditional laparoscopic surgery, pressing the button activates the suction device and initiates suction. Releasing the button stops the suction. During operation, the operator must continuously press the button to maintain suction. Furthermore, it is difficult to adjust the suction force precisely and in a timely manner according to specific tissue characteristics and surgical needs. This can lead to unnecessary damage due to excessive suction when dealing with fragile tissues, or insufficient suction when dealing with large amounts of fluid or bleeding, affecting surgical efficiency. Therefore, a laparoscopic surgical suction device with anti-slip, flexibility, and adjustable suction is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a laparoscopic surgical suction device with anti-slip, bendable and suction force adjustable functions.

The upper part of the adjusting block is slidably connected to the horizontal slide rail, and the lower part of the adjusting block abuts against the negative pressure hose.

[0010] Furthermore, the base is marked with negative pressure suction scale lines of 0%, 50%, and 100%.

[0012] Furthermore, it also includes a fixed shaft, a connecting plate, a plug rod, and a limiting block. The fixed shaft is fixedly connected to the outside of the support tube through the connecting plate. The support tube has a rotating hole through which the drive shaft passes.

The limiting block is fixedly connected to the handle body. The limiting block has a sliding hole through which the rod body passes and the rod head is inserted into one of the slots.

[0013] Furthermore, it also includes a slider and a compression spring. The slider is fixedly connected to the insertion rod and slidably connected to the handle. The slider is located between the limiting block and the fixed shaft. The compression spring is sleeved on the insertion rod, and the two ends of the compression spring abut against the limiting block and the slider, respectively.

A suction control device, consisting of a negative pressure hose, base, and adjustment block, is installed at the rear of the suction body. The adjustment block's position on the base determines the suction force, providing precise control over the suction level. These designs contribute to improved accuracy, convenience, and efficiency in laparoscopic surgery. Attached Figure Description

Detailed Implementation

[0033] This utility model provides a laparoscopic surgical suction device with anti-slip, bendable and suction-adjustable functions, which overcomes the shortcomings of traditional laparoscopic suction devices in the background art; it achieves the technical effect of having anti-slip, bendable and suction-adjustable functions, which helps to improve the accuracy, convenience and efficiency of laparoscopic surgery.

[0034] The overall concept of the technical solution of this utility model embodiment is as follows:

[0035] The front surface of the suction tube head is provided with anti-slip threads; the angle between the suction tube head and the suction tube body can be adjusted and flexibly bent through the connection relationship between the handle, drive shaft, drive adjusting wheel, transmission line, driven adjusting wheel, driven shaft and suction tube head; the suction control device, mainly composed of negative pressure tubing, base and adjusting block, is based on the liquid flow rate adjustment device of existing infusion devices in clinical practice. By operating the suction control device, the diameter of the negative pressure tubing is changed, and the magnitude of negative pressure suction is precisely controlled.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] See Figures 1 to 11 The preferred embodiment of this utility model.

[0038] A laparoscopic surgical suction device with anti-slip, bendable, and suction-adjustable functions includes:

[0039] Support tube 1, suction tube body 2, suction tube head 3, flexible tube 4, active adjusting wheel 5, active shaft 51, driven adjusting wheel 6, driven shaft 61, transmission line 7, handle 8, negative pressure hose 91, base 92 and adjusting block 93;

[0040] The suction tube body 2 is fixedly disposed in the inner cavity of the support tube 1. The rear end of the suction tube body 2 extends out from the rear end of the support tube 1. An angle adjustment port 11 is provided at the front end of the support tube 1. The rear end of the suction tube head 3 enters the angle adjustment port 11. The rear end of the suction tube head 3 is connected to the front end of the suction tube body 2 through the flexible tube 4. The front end surface of the suction tube head 3 is provided with anti-slip threads.

[0041] The active adjusting wheel 5 and the driven adjusting wheel 6 are both located inside the support tube 1. The center of the active adjusting wheel 5 is fixedly connected to one end of the active shaft 51, and the handle 8 is fixedly connected to the other end of the active shaft 51. The active shaft 51 is also rotatably connected to the support tube 1. The center of the driven adjusting wheel 6 is fixedly connected to one end of the driven shaft 61, and the suction tube head 3 is fixedly connected to the other end of the driven shaft 61. The driven shaft 61 is also rotatably connected to the support tube 1. The transmission line 7 is wound around the active adjusting wheel 5 and the driven adjusting wheel 6.

[0042] The front end of the negative pressure hose 91 is fixedly connected to the rear end of the suction tube body 2. The base 92 has a channel, with a horizontal slide rail 95 above the channel and an inclined surface 94 below the channel. The rear end of the negative pressure hose 91 passes through the channel. The upper part of the adjusting block 93 is slidably connected to the horizontal slide rail 95, and the lower part of the adjusting block 93 abuts against the negative pressure hose 91.

[0043] The beneficial effects of the above technical solution are that the anti-slip threads on the front surface of the suction tube head 3 significantly increase friction, ensuring stable contact between the suction tube head 3 and human tissue during surgical procedures and effectively preventing slippage. A flexible structure is adopted between the suction tube head 3 and the suction tube body 2. The suction tube head 3 can be bent using the operating handle 8, allowing for flexible adjustment of the bending angle according to the specific shape and depth of the surgical site. A suction control device 9, mainly composed of a negative pressure hose 91, a base 92, and an adjusting block 93, is installed at the rear end of the suction tube body 2. The base 92 is marked with negative pressure suction scale lines of 0%, 50%, and 100%. The adjusting block 93, positioned at different locations on the base 92, allows the suction device to generate different suction forces, providing the operator with precise control over the suction strength. This design helps improve the accuracy, convenience, and efficiency of laparoscopic surgery.

[0044] It also includes a three-way tube 96 and a cap 97. The first port of the three-way tube 96 is connected to the rear end of the suction tube body 2, the second port of the three-way tube 96 is connected to the front end of the negative pressure hose 91, and the third port of the three-way tube 96 is the irrigation port. The cap 97 is installed on the third port of the three-way tube 96. The beneficial effect of this technical solution is that when the surgical area needs to be irrigated during laparoscopic surgery, the adjusting block 93 on the base 92 is first moved to a position where the suction is zero. Then, the cap 97 is opened, and the irrigation port is connected to the existing irrigation device to flush saline or other liquids into the abdominal cavity. Because the adjusting block 93 completely clamps the negative pressure hose 91, and the negative pressure hose 91 is connected to the existing negative pressure drive device, saline cannot flow to the negative pressure drive device. The negative pressure drive device has a main negative pressure suction switch.

[0045] Combination Figure 6 The surgeon pushes the handle 8 forward, causing the active adjusting wheel 5 to rotate counterclockwise. Through the transmission line 7, the driven adjusting wheel 6 rotates counterclockwise, thus rotating the suction tube head 3 downwards. Figure 7 The surgeon pushes the handle 8 backward, which drives the active adjustment wheel 5 to rotate clockwise. With the help of the transmission line 7, the driven adjustment wheel 6 rotates clockwise, thus causing the suction tube head 3 to rotate upward.

[0046] Combination Figure 4 , Figure 8 and Figure 9The device also includes a fixed shaft 12, a connecting plate 13, an insertion rod 81, and a limiting block 82. The fixed shaft 12 is fixedly connected to the outside of the support tube 1 through the connecting plate 13. The support tube 1 has a rotating hole through which the drive shaft 51 passes. The handle 8 is located outside the support tube 1. The axis of the fixed shaft 12 is the same as the axis of the drive shaft 51. The surface of the fixed shaft 12 has multiple slots 14. The limiting block 82 is fixedly connected to the handle of the handle 8. The limiting block 82 has a sliding hole through which the rod of the insertion rod 81 passes. The tip of the insertion rod 81 is inserted into one of the slots 14. The beneficial effect of this technical solution is that the insertion rod 81 rotates with the rotation of the handle 8. When the insertion rod 81 is inserted into different slots 14, the handle 8 is fixed at different angles, thereby limiting the suction tube head 3 to different angles; preventing the bending of the suction tube head 3 from returning to its original position when using the bent suction tube head 3 to pull tissue and expose the surgical field.

[0047] It also includes a slider 83 and a compression spring 84. The slider 83 is fixedly connected to the insertion rod 81 and slidably connected to the handle 8. The slider 83 is located between the limiting block 82 and the fixed shaft 12. The compression spring 84 is sleeved on the insertion rod 81, and its two ends respectively abut against the limiting block 82 and the slider 83. The beneficial effect of this technical solution is that when the surgeon lifts the insertion rod 81 upwards, combined with... Figure 9 The insertion rod 81 drives the slider 83 to move upward, so that the compression spring 84 is in a compressed state. When the surgeon releases the insertion rod 81, the compression spring 84 returns to its original position and pushes the slider 84, so that the insertion rod 81 moves downward, which helps the insertion rod 81 to be stably inserted into the slot 14.

[0048] There are seven slots 14, which are evenly spaced on the semi-circular surface of the fixed shaft 12. The advantage of this technical solution is that it provides a handle angle variation range of 0° to 180°, with the angle variation between two adjacent slots 14 being 30°.

[0049] It also includes a flexible sealing sleeve 15, which is fitted over the connection between the suction tube head 3 and the support tube 1. The beneficial effect of this technical solution is to prevent blood and tissue fluid from flowing into the lumen of the support tube 1.

[0050] The flexible tube 4 is a corrugated tube.

[0051] Alternatively, both the active adjusting wheel 5 and the driven adjusting wheel 6 can be replaced with pulleys, and the transmission line 7 can be replaced with a transmission belt.

[0052] The working principle of this utility model is as follows: (1) The suction tube head 3 is located at the front end of the suction tube body 2, and the surface of the suction tube head 3 is carefully designed with threads. This threaded structure can significantly increase the friction force, ensuring that the suction tube head 3 and the tissue maintain stable contact during operation, and effectively preventing slippage. For example, when using a suction device to pry open and push the tissue to expose the surgical area, the threaded suction tube head 3 can be stably fixed in the target position, avoiding misoperation caused by slippage.

[0053] (2) An innovative flexible design is adopted between the suction tube head 3 and the suction tube body 2. This design allows the suction tube head 3 to be flexibly adjusted according to the specific shape and depth of the surgical site. When dealing with deep tissues, by bending the suction tube head 3, the target location can be reached more accurately for suction, while also playing a good role in traction and exposing tissues, providing a clearer field of vision and more convenient operating space for surgical operations. For example, when dealing with complex lesions located deep in the abdominal cavity, the suction tube head 3 can be bent to a suitable angle for precise suction and traction, so that areas that are originally difficult to reach can be fully treated.

[0054] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
