Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a rapid suture device for laparoscopic surgery. Background Technology

[0002] Minimally invasive laparoscopic surgery avoids the trauma of open surgery, enabling closed or localized surgeries with less trauma. Minimally invasive surgery typically involves the remote manipulation of instruments performed through small incisions in the skin, or through body cavities or anatomical openings, allowing indirect visualization of the surgical field via an endoscope or similar device. Minimally invasive laparoscopic techniques thus reduce tissue damage during diagnostic or surgical procedures, thereby reducing patient recovery time, discomfort, and adverse side effects. Consequently, minimally invasive techniques shorten the average length of hospital stay compared to standard open surgery.

[0003] One form of minimally invasive surgery is endoscopic surgery. The most common form of endoscopic surgery is probably laparoscopic surgery, which involves minimally invasive examination and surgery within the abdominal cavity. In a standard laparoscopic surgical procedure, air is blown into the patient's abdomen and a cannula is passed through a small (approximately 1 / 2 inch) incision to provide an entry point for laparoscopic surgical instruments. Laparoscopic surgical instruments typically include an endoscope for viewing the surgical field and, in some embodiments, specialized surgical instruments that pass through the entry point. These instruments may include, for example, clamps, grippers, scissors, suture devices, and needle holders. These surgical instruments may or may not be similar to those used in conventional (open) surgery; typically, the working end of each instrument is spaced from its handle by a slender shaft and is sized to fit through the entry point. To perform the surgery, the surgeon inserts the surgical instruments through the entry point to the surgical site inside the body and manipulates these instruments from outside the abdominal cavity. The surgeon monitors the procedure using a monitor that displays images of the surgical site taken from the laparoscopy.

[0004] However, after minimally invasive laparoscopic surgery of the posterior joint, sutures are needed to close the wound. During posterior joint surgery, the distance between the posterior joint and the soft tissue is very small. General surgical instruments are used to suture between the posterior joint and the soft tissue. However, the distance between the posterior joint and the soft tissue is very small, and general surgical instruments are too long to suture between the posterior joint and the soft tissue. This results in the need to repeatedly pass and hold the suture during the suturing process, which prolongs the operation time. Summary of the Invention

[0005] The technical problem to be solved by this invention is that the distance between the posterior joint and the soft tissue is too small to perform surgical suturing, which leads to the need for repeated suture passing and holding and the prolongation of surgical time. The purpose is to provide a rapid suture device for laparoscopic surgery that can achieve rapid suturing in the small distance between the posterior joint and the soft tissue, thereby improving the efficiency of the suture device.

[0006] This invention is achieved through the following technical solution:

[0007] A rapid suture device for laparoscopic surgery, comprising:

[0008] The suture body;

[0009] A connecting rod, one end of which is connected to the suture body;

[0010] The thread-strapping post is respectively installed inside the sewing machine body and the connecting rod body. One end of the thread pulls the push-pull device that can move axially. The push-pull device is equipped with a self-rotating threading device. The other end of the thread pull passes through the stop piece and is connected to the rotating roller through the outer circumferential surface of the thread-strapping post. The stop piece is fixed in the connecting rod body.

[0011] A suture rod, one end of which is connected to the other end of a connecting rod, and the other end of the suture rod has a push-pull device and the threading device inside;

[0012] An elastic element is provided between the push-pull device and the stop component, and the pull cable extends from the push-pull device through the elastic element and the stop component to the roller.

[0013] The thread-strapping post is fixed inside the sewing machine body and the connecting rod. The stop is a stop block with a through hole. The pull wire passes from the push-pull device through the elastic element and the through hole to the roller.

[0014] The elastic element is either a spring or a hollow rubber column.

[0015] The left and right ends of the elastic element abut against the end faces of the push-pull device and the stop, respectively.

[0016] The push-pull device is a push-pull block with an "L" shaped cross-section. The push-pull block can move axially within the stitching rod (5), and a rack is provided on the push-pull block.

[0017] The threading device includes: a gear, an inlet needle, and an outlet needle;

[0018] The gear meshes with the rack, and the inlet needle and outlet needle are located outside the gear, with the inlet needle and outlet needle connected together.

[0019] The gear has a suture channel inside, which is connected to the inlet needle and the outlet needle.

[0020] The suture rod has a threading channel inside, and a threading outlet and a threading inlet outside the suture rod. The threading channel is connected to the threading outlet and the threading inlet.

[0021] The left end of the suture rod is connected to the outer wall of the suture rod body, and a pin is fixedly connected to the inner side of the outer wall of the suture rod body. The gear is rotatably mounted on the pin.

[0022] The left end of the suture rod has a tapered needle, which is connected to the suture rod.

[0023] The left end of the connecting rod and the right end of the stitching rod are connected by welding or threaded connection.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] 1. The difference between this invention and traditional suturing tools lies in the fact that conventional surgical tools pass through the soft tissue from the left side, and are straight and inflexible, making operation extremely inconvenient. This invention reduces the length of the surgical tool by rotating the inlet and outlet needles on gears. The suture is clamped at the outlet needle's exit end and the suture exit point, and is held at the right end of the soft tissue. The rotation of the inlet and outlet needles does not change the distance between the joint bone and the soft tissue. With the inlet and outlet needles located at the left end of the soft tissue, the suture body rotates a certain angle along its axis, then positions the inlet and outlet needles at the right end of the soft tissue. The suture at the outlet needle's exit point is clamped for suturing. This allows for rapid suturing within a small distance between the posterior joint and the soft tissue, improving the efficiency of the suture device. It eliminates the need for repeated suture passing and gripping during the suturing process, reducing surgical time.

[0026] 2. The rotation of the gear in this invention reduces the length of the surgical tool when the suture needle and the suture needle rotate on the gear. Once the suture needle and the suture needle are at the left end of the soft tissue, the gear rotates clockwise, and the rotation of the suture needle and the suture needle reduces the length of the surgical tool.

[0027] 3. In the present invention, the elastic element is in an extended or compressed state. When the second handle rotates away from the first handle, the pull wire loosens the push-pull block, and the spring returns to its original extended state, causing the push-pull block to move to the left. The gear rotates clockwise. When the second handle rotates close to the first handle, the pull wire pulls the push-pull block, and the spring is compressed, causing the push-pull block to move to the left. The gear rotates counterclockwise. The rotation of the infeed needle and the outfeed needle reduces the length of the surgical tool. Attached Figure Description

[0038] Example 1

[0039] like Figure 1 As shown, a rapid suture device for laparoscopic surgery includes: a suture body 1, a connecting rod 2, a suture-straightening post 3, a pull suture 4, and a suture rod 5. The right end of the connecting rod 2 is connected to the suture body 1. The suture-straightening post 3 is respectively disposed inside the suture body 1 and the connecting rod 2. The left end of the pull suture 4 holds a push-pull device that can move axially. The push-pull device is equipped with a self-rotating threading device. The right end of the pull suture 4 passes through a stop and is connected to a rotating roller 13 through the outer circumferential surface of the suture-straightening post 3. The stop is fixed inside the connecting rod 2.

[0040] The right end of the suture rod 5 is connected to the left end of the connecting rod 2. The end of the suture rod 5 is integrally formed with the connecting rod 2, or the left end of the connecting rod 2 and the right end of the suture rod 5 are connected by welding or threaded connection. The right end of the suture rod 5 has a push-pull device and the threading device inside.

[0041] There is an elastic element 9 between the push-pull device and the stop component. The pull wire 4 goes from the push-pull device through the elastic element 9 and the stop component to the roller 13. The extension and retraction of the elastic element 9 causes the push-pull device to move left and right along the axis of the sewing rod 5 within the sewing rod body 5.

[0042] The thread-strapping post 3 is fixed inside the sewing machine body 1 and the connecting rod body 2. The stop is a stop block 10, which has a through hole 101. The pull wire 4 goes from the push-pull device through the elastic element 9 and the through hole 101 to the roller 13.

[0043] The threading device and the stop are connected by an elastic element 9, i.e., a spring. The elastic element 9 can be either a spring or a hollow rubber column. The left and right ends of the elastic element 9 abut against the end faces of the threading device and the stop 10, respectively. The pull wire 4 passes from the threading device through the elastic element 9 and the stop to the roller 13. The left and right ends of the elastic element 9 abut against the end faces of the push-pull device and the stop 10, respectively.

[0044] The thread-strapping post 3 is fixed inside the sewing machine body 1 and the connecting rod body 2. The stop is a stop block 10, which has a through hole 101. The thread 4 passes from the threading device through the elastic member 9 and the through hole 101 to the roller 13.

[0045] like Figure 2-3 As shown, the push-pull device is a push-pull block 8 with an "L" shaped cross-section. The push-pull block 8 can move axially within the suture rod 5. The left end of the suture rod 5 has a tapered needle 51, which is connected to the suture rod 5. The push-pull block 8 is provided with a rack 81.

[0046] The threading device includes: a gear 7, an inlet needle 72, and an outlet needle 74;

[0047] Gear 7 meshes with rack 81. Inlet needle 72 and outlet needle 74 are located outside gear 7, and inlet needle 72 and outlet needle 74 are connected.

[0048] The gear 7 has a suture channel 73 inside, which is connected to the inlet needle 72 and the outlet needle 74.

[0049] The suture rod 5 has a threading channel 53 inside, and a threading outlet 52 and a threading inlet 54 outside. The threading channel 53 is connected to the threading outlet 52 and the threading inlet 54.

[0050] The left end of the suture rod 5 is connected to the outer wall 6 of the suture rod body, and a pin is fixedly connected to the inner side of the outer wall 6 of the suture rod body. The gear 7 is rotatably mounted on the pin.

[0051] Example 2

[0052] Based on Example 1, such as Figure 1-3As shown, the lower end of the suture body 1 has a handle connecting block 11. There are two handle connecting blocks 11. The first handle 12 is connected to the lower end of the suture body 1 via the handle connecting block 11. The second handle 15 is connected to the handle connecting block 11, but the handle connecting block 11 to which the second handle 15 is connected is not connected to the lower end of the suture body 1. The handle connecting block 11 of the first handle 12 is clearance-fitted with the pin 14, while the handle connecting block 11 of the second handle 15 is interference-fitted with the pin 14. The handle connecting block 11 of the first handle 12 is located on the front side, and the handle connecting block 11 of the second handle 15 is... Located at the rear, there is a roller 13 between the front and rear handle connecting blocks 11. The roller 13 is interference-fitted with the pin 14. The second handle 15 can rotate relative to the first handle 12. When the second handle 15 rotates relative to the first handle 12, the roller 13 rotates. The right end of the pull cable 4 is wound around the outer circumference of the roller 13. When the second handle 15 rotates relative to the first handle 12, the pull cable 4 pulls the push-pull block 8, the spring 9 is compressed, and the push-pull block 8 moves to the right. When the second handle 15 rotates away from the first handle 12, the pull cable 4 is relaxed, the spring 9 returns to its original state, and the spring 9 moves to the left.

[0053] Example 3

[0054] like Figure 1-2 As shown, the left and right ends of the elastic element 9 abut against the end faces of the threading device and the stop block 10, respectively. That is, the elastic element 9 abuts between the push-pull block 8 and the stop block 10. The stop block 10 has a through hole 101. The pull wire 4 is tied to the right end of the push-pull block 8 and then passes through the elastic element 9, the through hole 101 and the winding post 3 to reach the rotating roller 13. The pull wire 4 is wound around the outer peripheral wall of the rotating roller 13.

[0055] When the second handle 15 rotates relative to the first handle 12, the pull cable 4 pulls the push-pull block 8, and the push-pull block 8 moves to the right. The elastic element 9 is in a compressed state. When the second handle 15 rotates away from the first handle 12, the pull cable 4 releases the push-pull block 8, and the spring 9 returns to its original state, causing the push-pull block 8 to move to the left. The rack 81 on the push-pull block 8 causes the gear 7 to rotate. The left and right movement of the push-pull block 8 causes the gear 7 to rotate clockwise or counterclockwise.

[0056] The clockwise or counterclockwise rotation of gear 7 causes the angle between the infeed needle 72 and the outfeed needle 74 and the suture rod 5 to change.

[0057] Example 4

[0058] In conjunction with the above embodiments, such as Figure 2-3 As shown, during posterior joint surgery, the joint bone 17 is on the left and the soft tissue 16 is on the right. The distance between the joint bone 17 and the soft tissue 16 is small. The usual surgical instruments pass through the soft tissue 16 from the left side. The usual surgical instruments are straight and cannot be bent. The small distance between the joint bone 17 and the soft tissue 16 makes it inconvenient to operate the sutures.

[0059] This invention utilizes a suture 18 that enters through the suture outlet 52, passes through the suture channel 53, and exits through the suture inlet 54. After exiting through the suture inlet 54, the suture 18 then passes sequentially through the inlet needle 72 and the suture channel 73, and finally exits through the outlet needle 74. After exiting through the outlet needle 74, the suture 18 can be held by a clamp. The suture 18 is held on the right side of the soft tissue 16, and the suture 18 on the right side of the soft tissue 16 can be threaded onto the outlet needle 74 for suturing.

[0060] Example 5

[0061] Specifically, one way to use this invention is as follows: Figure 3 As shown, the suture 18 is first inserted through the threading outlet 52 and finally exited through the exit needle 74. The suture 18 at the exit needle 74 is pulled out, and the suture 18 at the threading outlet 52 is clamped. The threading needle 72 and the exit needle 74 are inclined parallel to the axis of the suture rod 5. The conical needle 51 punctures the soft tissue 16 from the right end, while the threading needle 72 and the exit needle 74 are located at the left end of the soft tissue 16. Figure 2 As shown, when the second handle 15 is released, gear 7 rotates clockwise, and the infeed needle 72 and the outlet needle 74 form an angle with the axis of the suture rod 5. The suture body 1 rotates a certain angle along its axis, so that the infeed needle 72 and the outlet needle 74 are located at the right end of the soft tissue 16, and the suture 18 at the exit end of the outlet needle 74 is clamped. Then, the infeed needle 72 and the outlet needle 74 are located at the left end of the soft tissue 16, and the rotation of the suture body 1 along its axis is repeated. The procedure begins with the inlet needle 72 and outlet needle 74 positioned at the right end of the soft tissue 16, with the suture 18 at the outlet needle 74 being clamped. The inlet needle 72 and outlet needle 74 are positioned at the left end of the soft tissue 16. Finally, the second handle 15 is pressed to rotate the gear 7 counterclockwise, causing the inlet needle 72 and outlet needle 74 to align parallel to the axis of the suture rod 5. The inlet needle 72 and outlet needle 74 complete the surgical suturing from the left end to the right end of the soft tissue 16.

[0062] The difference between this invention and traditional suturing surgical tools is that conventional surgical tools pass through the soft tissue 16 from the left side, and conventional surgical tools are straight and cannot be bent. Since the distance between the joint bone 17 and the soft tissue 16 is small, moving the surgical tool slightly to the right increases the distance between the joint bone 17 and the soft tissue 16, which damages the wound. Moving the surgical tool slightly to the left also makes it difficult to pull out the suture at the right end of the surgical tool, making the operation extremely inconvenient.

[0063] This invention transforms a straight surgical tool into an angled exit needle 74 when the inlet needle 72 and outlet needle 74 rotate on the gear 7, reducing the length of the surgical tool. The suture 18 is clamped at the exit end of the outlet needle 74 and the suture outlet 52. The suture 18 is clamped at the right end of the soft tissue 16. The rotation of the inlet needle 72 and outlet needle 74 does not change the distance between the joint bone 17 and the soft tissue 16. The inlet needle 72 and outlet needle 74 are located at the left end of the soft tissue 16. The suture body 1 rotates a certain angle along its axis, and then the inlet needle 72 and outlet needle 74 are located at the right end of the soft tissue 16. The suture 18 at the exit end of the outlet needle 74 is clamped for suturing. This allows for rapid suturing within a small distance between the posterior joint 17 and the soft tissue 16, improving the efficiency of the suture device.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
