Description

Technical Field

[0001] This utility model relates to a suture device with adjustable flushing and suction smoke removal functions for laparoscopic surgery, belonging to the field of medical device technology. Background Technology

[0002] Laparoscopic surgery, as a mainstream minimally invasive surgical procedure, requires the establishment of a pneumoperitoneum to create an operating space. Specialized instruments are inserted through a trocar to complete the procedure. Laparoscopic staplers are the core instruments for intraoperative tissue anastomosis and incision closure. The mainstream types are needle holders or staple cartridges, with the end-effector suturing mechanism controlled by an external handle to achieve intraoperative tissue suturing.

[0003] Existing laparoscopic suction devices are essential for maintaining a clear surgical field. They are mostly long tubes connected to a negative pressure source for suctioning out oozing blood, irrigation fluid, and tissue debris. Irrigation is often integrated into the suction device, using tubing for saline injection and waste fluid reabsorption. Smoke extraction relies on a separate exhaust tube to remove surgical fumes generated by electrosurgical instruments. However, the implementation of these functions presents the following problems:

[0004] (1) Functional disruption and cumbersome operation: The suture device can only suture and has no suction, irrigation or smoke removal capabilities; the suction and irrigation device has no suturing function. The instruments need to be changed frequently during the operation. Each time the original instrument is changed, the original instrument must be removed and a new instrument must be inserted. Complex operations can require more than ten changes, which seriously disrupts the operation rhythm and prolongs the operation time.

[0005] (2) Affects the surgical field and safety: bleeding and fluid accumulation cannot be removed in time during suturing, which can obstruct the field of vision and easily lead to suturing deviation; (3) Increased risk of trauma and infection: repeated insertion and removal of instruments into and out of the puncture cannula can easily cause friction and tearing of the puncture site tissue, aggravating abdominal wall damage; repeated operations increase the probability of external bacteria entering the abdominal cavity and increase the postoperative infection rate.

[0006] (4) Poor instrument coordination and low efficiency: Multiple instruments require multiple channels to occupy, and they are prone to mutual interference and "fighting" in the narrow abdominal cavity; doctors need to be distracted to adapt to the feel and operation logic of different instruments, prolonging the learning curve, and are more likely to delay operation in emergency situations.

[0007] (5) Lack of smoke exhaust function: Mainstream suturing and suction instruments do not have dedicated smoke exhaust channels and cannot filter toxic fumes. In addition, the suction flow rate cannot be adjusted. When using a suction device to exhaust smoke, CO2 is lost rapidly, causing a sudden drop in pneumoperitoneum pressure and space collapse. Repeated adjustments exacerbate surgical instability. If an additional smoke exhaust tube is connected, the cost is high.

[0008] Therefore, there is an urgent need in this field to design a multifunctional and controllable suturing instrument to improve the operation of suturing, hemostasis, suction, irrigation and smoke removal during laparoscopic surgery. Utility Model Content

[0009] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a suture with outstanding practical functions, reasonable structural design, and adjustable rinsing, suction and smoke exhaust functions.

[0010] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution: A laparoscopic suture device with adjustable irrigation and suction functions includes a handle, an instrument rod, jaws, and a steering and propulsion mechanism. The jaws are connected to the handle via the instrument rod. The steering and propulsion mechanism is mounted on the handle and poweredly connected to the jaws via the instrument rod to control the jaws' swing within a preset angle. It also includes a suction tube, which is a single-lumen tube with an interconnected distal suction section and a proximal connector. The distal suction section is detachably connected to the jaws and swings synchronously with them. The proximal connector is detachably connected to the outer wall of the instrument rod and communicates with a control box, which contains control components. The device includes a smoke exhaust pipe, a suction connector, and a flushing connector. The control component is used to switch the connection between the proximal connector and the control box cavity, the smoke exhaust pipe, the suction connector, and the flushing connector. The suction pipe also includes a flexible bending section and a connecting section. The flexible bending section is a corrugated hollow tube, and the connecting section is a hollow tube. The end suction part is connected to the proximal connector in sequence through the flexible bending section and the connecting section. The end suction part is provided with a fixing buckle. The jaws have a pin seat. The pin seat has symmetrically opened sliding grooves on both sides. The fixing buckle is transitionally fitted and slidably embedded in the sliding groove.

[0011] Preferably, the control box is a four-way valve with a hollow inner cavity and an output connector. The control box is connected to the proximal connector through the output connector. The output connector has a channel one. The control box has a chamber that connects the channel one and the hollow inner cavity, a channel two that connects the exhaust pipe and the hollow inner cavity, a channel three that connects the suction connector and the hollow inner cavity, and a channel four that connects the flushing connector and the hollow inner cavity.

[0012] Furthermore, the top of the hollow inner cavity is open, and the control component is a rotary valve core that is rotatably and sealed within the hollow inner cavity of the control box. The control component has a through hole with the same diameter as the holes of channel one, channel two, channel three, and channel four. The upper part of the control component has a knob protruding from the surface of the control box to drive the rotation of the control component.

[0013] Furthermore, a filter element is sealed inside the second channel of the exhaust pipe.

[0014] Furthermore, the surface of the control box is provided with four status marks corresponding to the closed, smoke exhaust, suction and flushing states when the through hole is aligned with any of the status marks.

At the same time, it can be bent at any angle and swing with the jaw in different directions to perform corresponding suction operations. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1-9 The laparoscopic suture device with adjustable flushing and suction functions includes a handle 1, an instrument rod 2, jaws 3, and a steering and propulsion mechanism 4. The jaws 3 are connected to the handle 1 via the instrument rod 2. The steering and propulsion mechanism 4 is mounted on the handle 1 and is poweredly connected to the jaws 3 via the instrument rod 2 to control the jaws 3 to swing within a preset angle. The jaws 3 have replaceable staple cartridges and staple seats 31 with opening and closing settings. The above is the existing working structure of the laparoscopic suture device, which will not be described in detail.

[0022] Furthermore, the laparoscopic suture device with adjustable irrigation and suction / fume extraction functions also includes a suction tube 5. The suction tube 5 is a single-lumen tube with an interconnected distal suction section 51 and a proximal connector 54. The distal suction section 51 is detachably connected to the jaws 3 and swings synchronously with the jaws 3. The proximal connector 54 is detachably connected to the outer wall of the instrument rod 2 and connected to a control box 6. The control box 6 has a control element 61 and an integrally formed fume extraction pipe 62, a suction connector 63, and a flushing connector 64. The fume extraction pipe 62 is used to exhaust toxic fumes. The suction connector 63 is used to connect to the operating room negative pressure suction machine to achieve the suction function. The flushing connector 64 is used to connect to the operating room irrigation fluid pipeline to achieve the flushing function. The control element 61 is used to switch the connection between the proximal connector 54 and the inner cavity of the control box 6, the fume extraction pipe 62, the suction connector 63, and the flushing connector 64. This device integrates fume extraction, suction, and flushing functions and can be switched at any time as needed, thereby reducing the number of instrument changes, lowering surgical costs, and improving surgical efficiency.

[0023] Reference Figures 3-6 The control box 6 is a four-way valve with an integrally formed hollow inner cavity 65 and an output connector 66. The control box 6 is connected to the proximal connector 54 through the output connector 66. The output connector 66 has a channel 1 661. The control box 6 has a chamber 67 connecting the channel 1 661 and the hollow inner cavity 65, a channel 2 621 connecting the exhaust pipe 62 and the hollow inner cavity 65, a channel 3 631 connecting the suction connector 63 and the hollow inner cavity 65, and a channel 4 641 connecting the flushing connector 64 and the hollow inner cavity 65. Among them, the chamber 67 is an arc-shaped groove cavity. The channels 2 621, 3 631, and 4 641 are opened on opposite sides of the chamber 67, and the opening range of the arc-shaped groove chamber 67 completely covers the layout range of the channels 2 621, 3 631, and 4 641 on the opposite side.

[0024] The hollow inner cavity 65 is a circular cavity with an open top. The control component 61 is a rotary valve core, sealed and rotatably mounted in the hollow inner cavity 65 of the control box 6. The control component 61 has a through hole 612, the diameter of which is the same as that of the holes in channel one 661, channel two 621, channel three 631, and channel four 641. The upper part of the control component 61 has an integrally formed knob 611 protruding from the surface of the control box 6, which can be driven by the operator to rotate the control component 61. A filter element 7 is sealed and installed in channel two 621 of the exhaust pipe 62. The filter element 7 plays a role in flow restriction and filtration, filtering toxic smoke and preventing the gas belly from collapsing due to excessive flow.

[0025] Reference Figures 4-6 In a further embodiment, the surface of the control box 6 is engraved with four status marks 8: a closed mark, a smoke exhaust mark, a suction mark, and a flushing mark. The four status marks 8 correspond to the closed, smoke exhaust, suction, and flushing states when the through hole 612 is directly opposite any of the status marks 8. The upper part of the control member 61 has a triangular indicator 613 for indicating the state in which the through hole 612 is directly opposite one of the status marks 8. Specifically, when the triangular indicator 613 is aligned with the smoke exhaust mark, one end of the through hole 612 is aligned and connected to channel two 621, and the other end is connected to chamber 67 and channel one 661; when the triangular indicator 613 is aligned with the suction mark, one end of the through hole 612 is aligned and connected to channel three 631, and the other end is connected to chamber 67 and channel one 661; when the triangular indicator 613 is aligned with the flushing mark, one end of the through hole 612 is aligned and connected to channel four 641, and the other end is connected to chamber 67 and channel one 661; when the triangular indicator 613 points to the closed mark, the through hole 612 is not connected to any channel, thus achieving the effect of cutting off the negative pressure suction.

[0026] Reference Figures 1-9The suction tube 5 also includes a flexible bending section 52 and a connecting section 53. The flexible bending section 52 is a corrugated hollow tube, allowing it to bend at any angle. The connecting section 53 is a hollow tube used to connect and transport the aspirated body fluid. The end suction part 51 is connected to the proximal connector 54 through the flexible bending section 52 and the connecting section 53. A fixing buckle 511 is integrally formed on the end suction part 51. Sliding grooves 311 are symmetrically provided on both sides of the anvil seat 31 of the jaw 3. The fixing buckle 511 is smoothly fitted and slidably embedded in the sliding groove 311, which can realize the fixed connection between the flexible bending section 52 and the anvil seat 31. Furthermore, the smooth sliding setting of the fixing buckle 511 in the sliding groove 311 allows the operator to manually adjust the relative position of the end suction part 51 of the suction tube 5 and the jaw 3 with sufficient external force, which facilitates better suction operation. When the operator controls the jaws 3 to rotate through the steering and propulsion mechanism 4, the suction part 51 at the end of the suction tube 5 can swing in different directions with the jaws 3 to perform corresponding suction operations.

[0027] Furthermore, at least one fixing buckle 531 is integrally formed on the outer wall of the connecting section 53, which can be detachably engaged with the instrument rod 2, thereby realizing the detachable installation of the suction tube 5 and the instrument rod 2.

[0028] The working principle of the laparoscopic suture device with adjustable irrigation and suction smoke removal functions provided by this utility model is as follows: The suture device integrates a detachable and adjustable single-lumen suction tube 5, which swings with the jaws 3 at the head of the suture device and is adjustable in both front and back positions, offering high flexibility. The rear end of the single-lumen suction tube 5 is connected to a control box 6, allowing manual switching between flushing / suction / smoke extraction functions.

[0029] When the knob 611 on the control component 61 of the control box 6 is pointed to the smoke exhaust mark, the control box 6 connects the suction tube 5 to the smoke exhaust pipe 62. The filter element 7 inside the smoke exhaust pipe 62 acts as a flow limit filter, filtering toxic fumes and preventing abdominal collapse due to excessive flow. When the knob 611 is pointed to the suction mark, the suction tube 5 is connected to the operating room negative pressure suction machine, enabling suction. When the knob 611 is pointed to the irrigation mark, the suction tube 5 is connected to the operating room irrigation fluid pipeline, enabling irrigation. When the knob 611 is pointed to the off mark, the suction tube 5 is closed, there is no negative pressure, the abdominal pressure is kept constant, and hyperventilation is avoided.
