[0040] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] In laparoscopic surgery in the field of laparoscopic puncture, an operating channel is established, but the traditional design of laparoscopic puncture devices is inconvenient and has safety hazards during the suturing stage. The need to insert and remove the instrument back and forth in the operating channel may increase the risk of infection and damage to surrounding tissues, and an additional suturing device is required to suture the puncture hole after the operation, which increases the number of surgical steps and time. Specifically, the existing puncture device requires an additional suturing device to suture the puncture hole after the operation, which increases the number of surgical steps and time. Multiple insertions and removals of instruments may increase the risk of infection and damage to surrounding tissues. In addition, puncture devices with integrated suturing systems, such as the Progl ide vascular suturing device, need to be moved down a certain depth in the abdominal cavity to deploy the suturing system, which may not be applicable when the abdominal cavity space is limited.

[0042] The suture-type laparoscopic puncture device of the present invention is composed of a sleeve 1, a puncture needle, a suture 11 and the like.

[0043] The goal of the present invention is to combine a laparoscopic puncture device with a suture 11, so that doctors can use the present invention to perform abdominal puncture, laparoscope entry, and suturing of the laparoscopic puncture hole, so that multiple functions can be integrated into one device for use.

[0044] The appearance of this suture-type laparoscopic puncture device is as follows Figure 1 As shown: the puncture needle includes a puncture rod 2 and a puncture needle head 3; a stapler driving part 5 is arranged on the outer surface of the sleeve 1.

[0045] Combination Figure 4 The bottom of the inner wall of the sleeve 1 is connected to a rotating shaft 9 for fixed axis rotation. A thread foot body 10 is fixed to the side of the rotating shaft 9 facing the puncture rod 2. The thread foot body 10 is plate-shaped and hollowed out in the center. The hollowed-out part is used for the entry and exit of the laparoscope and other instruments. The thread foot body 10 is annular as a whole. The thread foot body 10 is initially tilted. Figure 3 As shown, in order to reduce the space occupied by the molding body 10, it is assembled in the sleeve 1;

[0046] Continue to see Figure 4 Two sections of slide grooves are provided on the molding body 10, and a slider 12 is slidably connected to the groove wall of the slide groove. A ball 11 is embedded in the upper end of the slider 12, and a pull rod 6 is fixedly connected to the upper surface of the ball. Connecting rods 13 are fixed on the opposite sides of the two sliders 12, and a push plate 14 is fixed to the end of the connecting rod 13. The push plate 14 is located in a cavity 15 provided in the molding body 10. A connecting cavity 16 is also provided inside the molding body 10. The connecting cavity 16 is connected to the cavity 15. When the push plate 14 slides in the cavity 15, the gas in the cavity 15 is compressed, and then the push block 17 can be pushed to move in the connecting cavity 16 under the action of pressure, so that the connecting rod 18 and the docking joint 19 connected to the push block 17 can move synchronously, such as Figure 4 The two docking joints 19 thereon will move synchronously in opposite directions to achieve the expansion of the docking joints 19.

[0047] Combination Figure 1 , 6 , 7. The end of the pull rod 6 is fixedly connected with a slide column 25, and the slide column 25 extends out of the sleeve 1. The upper handle of the sleeve 1 is rotatably connected with a turntable 20. Two connecting plates 21 are fixedly connected to the side of the turntable 20. A moving groove 23 is opened on the outer surface of the connecting plate 21. The moving groove 23 slides with the sleeve column 24. The sleeve column 24 is sleeved and fixed on the slide column 25, and a magnetic block 22 is fixed to the groove wall of the moving groove 23. When the sleeve column 24 slides to the end along the moving groove 23, the sleeve column 24 is made of metal, and then the magnetic block 22 attracts the sleeve column 24 to achieve the purpose of magnetic locking. Therefore, the rotation of the turntable 20 will drive the two pull rods 6 to move vertically, such as Figure 2The left pull rod 6 moves upward, and the right pull rod 6 moves downward, so that the molding body 10 moves from an inclined state to a horizontal state;

[0048] When the main body 10 of the thread foot is horizontal, the docking head 19 on it also expands outward and is located on both sides of the abdominal perforation. At this time, the pressing part on the suture drive unit 5 is pressed downward to move the two guide needles on the suture drive unit 5 out and penetrate into the abdominal cavity. The two guide needles will dock with the two docking heads 19, and the suture thread heads embedded in 19 are connected to the guide needles. After docking with the docking head 19, the guide needle on one side automatically falls off and connects the connecting wire inside the guide needle with the suture thread. The guide needle on the other side is stably connected to the docking head 19. At this time, the pressing part on the suture drive unit 5 is pulled upward, so that the connecting wire can be combined with the two wires, thereby achieving the purpose of suturing in the abdominal cavity. When the suturing is completed and the whole needs to be moved out, the whole device is retracted from the extended state, and the whole device is moved downward out of the body. It should be noted that the basic working principle of the main body of the thread foot belongs to the prior art, that is, similar to the operating principle of the Progl ide vascular suturer. The innovation of this case is to integrate the suturer into the abdominal puncture device and make a targeted design.

[0049] Both ends of the suture 11 are fixed to the two butt joints 19, and the middle section of the suture 11 is limited by the limit hook 30 (combined with Figure 7 ), the limit hook 30 is fixedly connected to the inner wall of the sleeve 1, so that the internal suture line 11 is in an inclined state to avoid blocking the entry and exit of the instrument in the middle of the sleeve 1.

[0050] When the present invention is used, the first use case is: the user first holds the cannula 1, so that the puncture needle 3 penetrates into the abdominal area to be operated on, so as to make an abdominal puncture hole in the abdominal cavity. After the hole is opened, the puncture needle is separated from the cannula 1, and the puncture needle is pulled out upward from the cannula 1, and then a cannula 1 is left in the patient's body. At this time, the tools to be used, such as a puncture scope and other equipment, are placed from the cannula 1 from top to bottom to explore the situation in the patient's abdominal cavity;

[0051] The second usage scenario of the present invention is that after the use of other tools such as the puncture endoscope, the puncture hole needs to be sutured. Different from the existing method, a puncture device is used for puncture and a suturing device is used for suturing, the present method directly integrates a convenient suturing system on the puncture device.

[0052] The user first rotates the turntable 20 clockwise to make the connecting plate 21 and the moving groove 23 rotate synchronously, and then under the sliding cooperation between the moving groove 23 and the sleeve 24, the left pull rod 6 is finally moved upward and the right pull rod 6 is moved downward. When the pull rod 6 moves vertically, the ball 11 is driven to move upward. Due to the embedded relationship between the ball 11 and the slider 12, and the rotation relationship between the molding body 10 and the sleeve 1 through the rotating shaft 9, the molding body 10 is rotated clockwise, as shown in FIG. Figure 3 As shown in the perspective, the slider 12 will slide in the slide groove to adapt to the rotation of the component to avoid jamming, and finally the stitch body 10 will be turned from an inclined state to a horizontal state. The stitch body 10 in the horizontal state is convenient for subsequent docking with the guide needle on the suture drive unit 5, and then the operation of this mode serves the purpose of unfolding the component in the patient's abdominal cavity. When not in use, it serves the purpose of folding and storing in the sleeve 1, and when other components such as the puncture mirror enter and exit the sleeve 1, obstruction is avoided, so that the two docking joints 19 are respectively on the left and right sides of the puncture hole; wherein, the stitch body is initially retracted inside the sleeve, which is one of the effects of the puncture device. Only by tilting and shrinking the stitch body inside the sleeve can the suturing device be integrated in the puncture device to avoid obstruction when the puncture device penetrates the patient's skin.

[0053] Then, as the slider 12 moves laterally, the connecting rod 13 and the push plate 14 will be driven to move laterally. The push plate 14 will compress the gas in the cavity 15, and then give thrust to the push block 17 through the connecting cavity 16, so that the push block 17 drives the connecting rod 18 and the docking joint 19 to move laterally, and finally Figure 4As shown, the upper connecting rod 18 moves right and the lower connecting rod 18 moves left, so that the left and right docking joints 19 extend outward. This is different from the existing abdominal suture device, which usually needs to move downward a certain distance to rotate and unfold the stitching foot body 10 when unfolding the stitching foot body 10. In this method, the downward movement of the sleeve 1 is less than the downward movement of the existing structure, so that the stitching foot body 10 is first rotated slightly to be initially unfolded, and then synchronously unfolded to a large extent after the rotation is completed, so that the docking between the guide needle and the docking joint 19 is met, and the vertical movement distance of the entire device is reduced, so as to avoid the unfavorable situation of obstruction and touching bleeding in the local narrow position of the abdominal cavity caused by excessive inward movement of the device, and has higher safety, because in the local narrow position of the patient's abdominal cavity, in order to improve safety, the puncture device cannot move downward too much, while in the prior art Progl The existing product, the IDE vascular suture device, needs to be moved down to a certain depth before the suturing system can be deployed. The present device is superior to the existing device and can deploy the suturing system to the same range without moving down too far, so as to ensure the subsequent docking of the inner and outer sutures and the suturing of the puncture holes. It should be noted that the "guide needle" and the "docking of the guide needle with the docking head" belong to the existing technology and are integrated in the suturing device drive unit 5.

[0054] After that, the joint 19 is fully unfolded and the whole structure is pulled upward, so that the thread leg body 10 is pressed against the inner wall of the patient's abdominal cavity. As for the operation principle of suturing, the pressing part above the suture device driving part 5 is pressed, such as Figure 1 As shown, that is, the structure similar to the pressure plate on the suture drive unit 5, so that the two guide needles in the suture drive unit 5 are tilted and extended downward, which is the prior art, and finally the two guide needles drive the connecting line, that is, the external suture line, to dock with the internal docking head 19. After docking, the guide needle on one side is stably connected to the docking head 19, and the guide needle on the other side is disconnected from the connecting head 19, and the external suture line is connected to one end of the internal suture line 11, and then the guide needle at the other end of the stable docking is pulled, so that the external suture line 11 passes through the device into the patient's abdominal cavity and is located on both sides of the puncture hole. Finally, the sleeve 1 is pulled out upward after the suturing is completed, wherein Figure 3 and Figure 5 The limiting hook 30 serves the purpose of limiting the position of the suture 11. When the sleeve 1 is pulled out as a whole, the opening of the limiting hook 30 faces in the direction so that the suture 11 is retained in the patient's abdominal cavity, thereby achieving the purpose of suturing;

[0055] It is worth noting that the present invention integrates the stapler into the puncture device. The suturing-related movements and effects involved in the text are based on the movements and effects of the stapler in the prior art, and the operating principle of the Progl ide vascular stapler can be referred to. The two docking heads 19 in the prior art need to be unfolded after entering the patient's body, and the innovation points of the present application document are:

[0056] First, the stapler is innovatively integrated into the puncture device.

[0057] Secondly, after integration, it plays a avoiding role and will not affect the normal penetration of the trocar into the patient's body, and will not block or affect the normal operation of the trocar.

[0058] Third, after the two docking joints 19 enter the patient's body, they can be unfolded with a small downward movement, without a deeper downward movement to unfold, because if the two docking joints 19 can only be deflected as a whole but cannot expand outward, the overall puncture device must be moved down to a sufficient depth to stretch, just like a wound to be sutured has a certain range, the two docking joints 19 and the main body of the stitching foot 10 form a surface, and this surface is initially tilted to enter the patient's body, and after entering the patient's body, it needs to be rotated and stretched, so this surface is bound to be rotated, so there is a trajectory, then the existing two docking joints 19 and the main body of the stitching foot 10 cannot be stretched as a whole, then the overall main body of the stitching foot 10 needs to be moved down to a certain depth before it can be unfolded, so as to avoid the rotation trajectory operation that blocks the normal rotation of the two docking joints 19, and the two docking joints 19 of the present application document can be retracted, so it can be understood as a directional change in the overall rotation radius and the size of the rotation trajectory of the two docking joints 19, thereby achieving the purpose of reducing the downward movement depth of the puncture device. Therefore, the trocar does not need to be moved too deeply downward, and is therefore safe.

[0059] When not suturing, it is stored in the sleeve of the laparoscopic puncture device to avoid blocking the sleeve from entering and exiting the laparoscope and other components. When suturing, the suturing system can be deployed to integrate the working principle of the Progl ide vascular suture device into the present device, and considering the purpose of avoiding structural obstruction when entering and exiting the abdominal cavity through the sleeve, the sleeve and the puncture part of the present device do not need to be moved down a deep distance. Because the abdominal cavity is in a narrow position, in order to improve safety, the puncture device cannot be moved down a lot, and the existing product such as the Progl ide vascular suture device needs to be moved down to a certain depth before the suturing system can be deployed. Obviously, the present device is superior to the Progl ide vascular suture device in this respect. It does not need to be moved down a lot, and the suturing system can be deployed to the same range to ensure the subsequent docking of the internal and external sutures and the suturing of the puncture holes.

[0060] The above are preferred embodiments of the present invention. Those skilled in the art may also make respective changes or improvements thereon. Without departing from the general concept of the present invention, these changes or improvements shall fall within the scope of protection claimed by the present invention.
