[0028] Reference Figure 1, a laparoscopic surgical auxiliary device includes a connecting seat 100, a guide tube 200 and a control component, wherein an avoidance straight groove 110 is provided on the outside of the connecting seat 100, one end of the avoidance straight groove 110 passes through one side of the connecting seat 100; one end of the guide tube 200 passes through the other side of the connecting seat 100 and extends into the avoidance straight groove 110, and a first lumen 210 and a second lumen 220 are formed inside the guide tube 200, the first lumen 210 passes through the guide tube 200 along the axial direction, and the second lumen 220 extends to the guide tube 200 away from the connecting seat. At one end of the connecting seat 100, a pipe joint 230 is provided on the outside of the guide tube 200 at a position corresponding to the avoidance straight groove 110. The pipe joint 230 is connected to the second tube cavity 220. In actual application, in order to facilitate the connection of the pipe joint 230 with the functional components of the external device, a thread, annular teeth and other structures can be provided on the outside of the pipe joint 230; the control component is provided on the connecting seat 100, and the control component is transmission-connected to the guide tube 200. The control component can drive the guide tube 200 to move along the length direction of the avoidance straight groove 110.

[0029] As can be seen from the above, the connecting seat 100 can be used for hand-held fixation, or it can be hung on an external instrument. The first tube cavity 210 is used for external instruments such as grasping forceps and electric knives to be inserted, so as to reach the target position for surgical operation, and functional components such as flushing water pumps and negative pressure pumps can be connected to the pipe connector 230. Through the second tube cavity 220, the target position can be suctioned, flushed, etc. When in use, the functional components connected to the pipe connector 230 can be directly replaced according to the need for suction or flushing of the target position to quickly meet different functional usage requirements. When it is necessary to adjust the distance between the guide tube 200 and the target position, the control component can be used to adjust the distance between the guide tube 200 and the target position. The movable guide tube 200 moves along the length direction of the avoidance straight groove 110, so that the first tube cavity 210 and the second tube cavity 220 are closer to the target position. The overall structure is simple and can be conveniently hung on an external instrument for fixed use, which is beneficial to improving the flexibility and coordination of surgical operations. In addition, it is directly connected to different functional components through the pipe connector 230 to switch different functions, saving the steps of frequently extracting and inserting the aspirator, irrigator, etc., effectively improving the efficiency of surgical operations, and the guide tube 200 can also be flexibly adjusted to reach the surgical operation position, thereby improving the accuracy and safety of surgical operations.

[0030] There are many ways for the control component to drive the guide tube 200 to move. For example, the control component drives the guide tube 200 to move by sliding. In this embodiment, the guide tube 200 is driven by the power of the reel. Specifically, Figure 2As shown, a connecting portion 120 is formed on the side of the connecting seat 100 away from the guide tube 200, and the control component includes a winding shaft 310 and a winding belt 320. The winding shaft 310 is rotatably connected to the connecting portion 120, one end of the winding belt 320 is connected to the outside of the winding shaft 310, the winding belt 320 is wound on the outside of the winding shaft 310, and the other end of the winding belt 320 is connected to the guide tube 200. When the guide tube 200 is extended out of the connecting seat 100 to approach the target position, the winding shaft 310 is rotated to drive the tape 320 on the outside of the winding shaft 310 to unwind. At this time, the tape 320 is released, which can push the guide tube 200 to extend out of the connecting seat 100; when it is necessary to drive the guide tube 200 to retract into the connecting seat 100 to move away from the target position, the winding shaft 310 is rotated in the opposite direction to drive the tape 320 on the outside of the winding shaft 310 to rewind. At this time, the guide tube 200 can be pulled into the connecting seat 100, thereby moving away from the target position. In this way, the position of the guide tube 200 can be adjusted stably and efficiently, thereby further improving the accuracy and safety of the surgical operation.

[0031] In order to avoid the tape 320 from entering the connection base 100, an avoidance structure can be provided in the connection base 100 at the position corresponding to the tape 320. Specifically, a limiting groove 111 is provided at the bottom of the avoidance straight groove 110. One end of the limiting groove 111 passes through the side of the connection base 100 near the connection portion 120. The guide tube 200 is formed with a connecting protrusion at the outer position corresponding to the limiting groove 111, and the tape 320 is connected to the connecting protrusion. The tape 320 can be fixed to the connecting protrusion by hooking, snapping, welding, or screwing, thereby quickly and firmly fixing the tape 320 to the guide tube 200. In this case, the limiting groove 111 can avoid the tape 320 and the connecting protrusion, which is conducive to improving the smoothness of the movement of the guide tube 200. During use, the end position of the limiting groove 111 can also be used to block the connecting protrusion, thereby limiting the stroke of pushing the guide tube 200 out. In addition, the two sides of the limiting groove 111 can also be used to limit the two sides of the connecting protrusion, thereby limiting the position of the guide tube 200 on the bottom side of the guide tube 200, which is beneficial to prevent the guide tube 200 from rotating and improve the stability of the guide tube 200 movement.

[0032] In the above embodiment, only a deeper hole can be provided in the connecting seat 100 for cooperating with the guide tube 200, so that the guide tube 200 is connected to the connecting seat 100 and the guide tube 200 slides relative to the connecting seat 100. In order to further improve the sliding stability of the guide tube 200, a structure that surrounds the guide tube 200 can be extended on the outside of the connecting seat 100. Specifically, an outer sleeve 130 is formed on the outside of the connecting seat 100, and one end of the guide tube 200 passes through the outer sleeve 130 and extends into the avoidance straight groove 110. The end face of the guide tube 200 away from the connecting seat 100 is set as a bevel surface 131. The outer sleeve 130 can increase the area of ​​protection surrounding the guide tube 200, allowing the guide tube 200 to slide inside, further improving the stability of the guide tube 200 sliding relative to the connecting seat 100. When in use, the end of the guide tube 200 away from the connecting seat 100 can be directly inserted into the body. At this time, the beveled surface 131 can assist the guide tube 200 to enter the patient's wound position, improve the smoothness of placing the guide tube 200 in place, and help reduce harm to the patient.

[0033] As the travel of the guide tube 200 increases, the length of the retaining groove 111, which provides space for the connecting protrusion and the tape 320 to move, needs to be correspondingly increased. To make the overall structure more compact, in this embodiment, the retaining groove 111 extends into the guide tube 200. This reduces the volume of the main body of the connecting base 100 while providing space within the guide tube 200 for the retaining groove 111, thereby better controlling the overall volume and improving operational flexibility.

[0034] In the above embodiment, if the winding shaft 310 needs to be rotated, force can be applied directly to the end of the winding shaft 310 to rotate it. To improve ease of use, in this embodiment, one end of the winding shaft 310 protrudes from the connecting portion 120 and is connected to a knob 330. When the winding shaft 310 needs to be rotated, force can be applied to the knob 330, thereby driving the winding shaft 310 to rotate and rewind the tape 320. In actual use, the outer periphery of the knob 330 can be provided with stripes to increase the friction around the knob 330, effectively preventing slipping when rotating the knob 330 and improving the user experience.

[0035] When an external instrument needs to enter the first tubular lumen 210, it can be directly inserted into the first tubular lumen 210. In order to improve the convenience of entering the first tubular lumen 210, a structure that stabilizes the instrument can be provided on the connecting portion 120. Specifically, a support block 340 is connected to the top side of the connecting portion 120, and a positioning groove 341 is provided on the top side of the support block 340 corresponding to the position of the first tubular lumen 210. When it is necessary to insert an instrument, the instrument can be placed on the support block 340 first and the positioning groove 341 is used to limit the position of the instrument. At this time, the instrument and the first tubular lumen 210 can be easily aligned with each other, and then the instrument can be inserted into the first tubular lumen 210. This can improve the efficiency of inserting the instrument into the first tubular lumen 210.

[0036] To facilitate detection of the depth of the guide tube 200 inserted into the body, in this embodiment, a scale is provided along the length of the tape 320. When rewinding or unwinding the tape 320, the scale on the tape 320 allows for intuitive identification of the unwound position of the tape 320, thereby conveniently observing the extent of the tape 320's movement relative to the guide tube 200 and improving the precision of control over the movement of the guide tube 200.

[0037] The cross section of the second lumen 220 can be circular, rectangular, etc., and in order to increase the coverage area of ​​the second lumen 220 during suction and flushing, as shown in FIG. Figure 3 and Figure 4 As shown, in this embodiment, the second lumen 220 extends in an arc shape around the axis of the guide tube 200. The arc-shaped second lumen 220 can increase the coverage range, thereby improving the effect of suction and flushing, and taking into account the structural stability of the guide tube 200, preventing the guide tube 200 from having insufficient structural strength due to the excessively large internal holes. In actual applications, in order to conduct with the second lumen 220, the pipe connector 230 can be directly inserted into the hole preset on the outside of the connecting seat 100. At this time, a connecting hole that is interconnected with the second lumen 220 is opened on the outside of the end of the pipe connector 230; or when the end of the pipe connector 230 is inserted into the hole preset on the outside of the connecting seat 100, the pipe connector 230 reserves space for gas and liquid circulation at the bottom of the hole.

[0038] To prevent smoke and liquid from directly entering the second lumen 220, in this embodiment, a valve 221 is provided at the end of the second lumen 220 away from the connector 100. The outer edge of the valve 221 is connected to one side of the second lumen 220, and the middle portion of the valve 221 protrudes toward the other side of the second lumen 220, shielding the second lumen 220. In its natural state, the middle portion of the valve 221 abuts against the sidewall of the second lumen 220, thereby blocking and sealing the interior of the second lumen 220 and effectively preventing smoke and accumulated liquid from entering the second lumen 220 on their own. When the second lumen 220 is connected to an external functional component for suction or flushing operations, the suction or flushing pressure can push the middle portion of the valve 221 toward the outer edge of the valve 221, thereby opening the interior of the second lumen 220. This ingeniously achieves the opening and closing of the second lumen 220.

[0039] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
