Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a laparoscopic surgery suturing device. Background Art

[0002] With the rapid development of medical technology, minimally invasive surgical techniques, especially laparoscopic surgical techniques, have become an important part of modern surgery. Laparoscopic surgery has greatly improved the patient's surgical experience and quality of life after surgery with its unique advantages, such as tiny surgical incisions, rapid postoperative recovery, and lower pain perception. However, although this technology has achieved remarkable results in reducing trauma and accelerating recovery, its surgical suturing process still faces many challenges. Among them, the shortcomings of traditional suturing forceps in the suturing process are particularly prominent, especially the limitations in incision crowding, which directly affects the surgical effect and the patient's postoperative recovery.

[0003] During the suturing process, traditional laparoscopic surgical suturing devices mainly rely on the pulling force of the suture thread to close the wound. This single closing method will cause secondary damage to the incision tissue when faced with large tension or excessive pulling force. In addition, since the suture forceps themselves lack the ability to effectively squeeze the incision, it is difficult for the incision to form stable scar tissue during the healing process, which in turn affects the healing speed and effect of the wound. In addition, the occurrence of complications such as incision dehiscence and bleeding will further delay the wound healing process, increasing the patient's pain and medical costs.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-Figure 10 The present invention provides a technical solution: a laparoscopic surgical suturing device, comprising a housing 1, a clamp seat 5 arranged at the front end of the housing 1, a clamp assembly 6 arranged on the clamp seat 5, and a movable handle 2, a fixed handle 3 and a reset spring 4 arranged at the rear end of the housing 1, the clamp assembly 6 comprising a rotating shaft 601 rotatably mounted on the clamp seat 5, a first clamp arm 602 and a second clamp arm 603 relatively rotatably mounted on the rotating shaft 601;

[0054] The clamp assembly 6 is provided with a squeeze assembly 8 for squeezing the incision, and the squeeze assembly 8 includes:

[0055] The active member 801 is mounted on the arc-shaped outer walls of the first clamp arm 602 and the second clamp arm 603 in a mirror image;

[0056] The follower 802 is slidably connected to the first clamp arm 602 and the second clamp arm 603, and a support spring 803 is fixedly connected to the bottom surface thereof, and the bottom end of the support spring 803 is fixedly connected to the inner bottom wall of the first clamp arm 602 and the second clamp arm 603;

[0057] A driving rack 805 is slidably connected to the inside of the first clamp arm 602 and the second clamp arm 603, one end of which is rotatably connected to a driving rod 806, and the other end of the driving rod 806 is rotatably connected to the side wall of the follower 802;

[0058] The transmission shaft 807 is rotatably mounted inside the first clamp arm 602 and the second clamp arm 603, and a driving gear 808 meshing with the driving rack 805 is fixedly mounted on its outer wall. The top end of the transmission shaft 807 extends to the end surfaces of the first clamp arm 602 and the second clamp arm 603 and is fixedly connected to a squeeze plate 809.

[0059] Specifically, when the clamp assembly 6 is in an unclamped state, the first clamp arm 602 and the second clamp arm 603 are in an open position, and the components of the squeeze assembly 8 are also in an initial position. The follower 802, under the action of the support spring 803, maintains a certain distance from the inner wall of the first clamp arm 602 and the second clamp arm 603;

[0060] The doctor operates the movable handle 2 and the fixed handle 3 to make the first clamp arm 602 and the second clamp arm 603 of the clamp assembly 6 rotate relative to each other and close, thereby clamping the surgical incision.

[0061] As the first clamp arm 602 and the second clamp arm 603 are closed, the active member 801 can rotate along with the rotation of the first clamp arm 602 and the second clamp arm 603. The active member 801 has a certain variable diameter curved surface, so that the active member 801 drives the driven member 802 to move downward during the rotation and overcomes the elastic force of the supporting spring 803. The side wall of the driven member 802 is rotatably connected to the driving rod 806. Therefore, the movement of the driven member 802 drives the driving rod 806 to translate, thereby pushing the driving rack 805 to slide inside the first clamp arm 602 and the second clamp arm 603.

[0062] The sliding of the driving rack 805 meshes with the driving gear 808 on the transmission shaft 807, driving the transmission shaft 807 to rotate. The rotation of the transmission shaft 807 drives the squeezing plate 809 to move along its axial direction, that is, to advance in the direction of the surgical incision. When the squeezing plate 809 contacts the surgical incision, as the transmission shaft 807 continues to rotate, the squeezing plate 809 will apply squeezing force to the incision, promoting the tissues on both sides of the incision to fit more closely, which is beneficial to healing or subsequent suturing operations. After the operation is completed, the doctor operates the movable handle 2 to open the clamp assembly 6. At the same time, the various components of the squeezing assembly 8 return to the initial position under the action of the support spring 803, etc., ready for next use. The squeezing assembly 8 realizes the automatic squeezing function of the surgical incision, thereby improving the surgical efficiency and suturing quality.

[0063] See also Figure 1-Figure 7 The housing 1 is a hollow tubular structure, the clamp seat 5 is threadedly connected to the front end of the housing 1, and the housing 1 is provided with an adjusting component 7 for driving the clamp assembly 6 to rotate the clamp and open it;

[0064] The adjustment component 7 comprises,

[0065] The push rod 701 is arranged inside the housing 1 and can slide along the length direction of the housing 1 under the drive of the movable handle 2. A slide groove 702 is provided on the push rod 701, and a slide rod 703 is slidably installed inside the slide groove 702;

[0066] The adjusting bolt 704 is threadedly connected to the outer wall of the housing 1 near the movable handle 2. A threaded ring 705 is threadedly connected to the outer wall of the adjusting bolt 704. A connecting rod 706 is rotatably connected to the outer wall of the threaded ring 705. The other end of the connecting rod 706 is hinged to the sliding rod 703.

[0067] A transmission rack 707 is integrally formed at one end of the slide slot 702 away from the connecting rod 706, and its teeth are located on the side wall of the slide slot 702;

[0068] The top rod 708 has a head end extending along the length direction of the push rod 701 and a tail end penetrating through the rear side wall of the clamp seat 5 and extending to the interior of the clamp seat 5;

[0069] The transmission gear 709 is fixedly mounted on the outer wall of the rotating shaft 601 and meshedly connected with the transmission rack 707 .

[0070] Specifically, when the doctor holds and operates the movable handle 2, the movable handle 2 transmits force to the push rod 701 through a mechanism that is not directly described, but may include a transmission mechanism such as gears, and the push rod 701 then slides along its length direction inside the shell 1; the slide groove 702 opened on the push rod 701 provides a sliding track for the slide rod 703. As the push rod 701 moves, the slide rod 703 slides inside the slide groove 702. This design allows the slide rod 703 to maintain contact with the slide groove 702 when the push rod 701 moves. For flexible adjustment of the position, the adjusting bolt 704 is threadedly connected to the outer wall of the housing 1 near the end of the movable handle 2, allowing the doctor to adjust its position by rotating the adjusting bolt 704. The threaded ring 705 is threadedly connected to the adjusting bolt 704 and moves up and down with the rotation of the adjusting bolt 704. The connecting rod 706 rotatably connected to the outer wall of the threaded ring 705 converts the vertical movement of the threaded ring 705 into the horizontal movement of the sliding rod 703, and is connected to the sliding rod 703 through the hinge point to realize the transmission of force and the conversion of direction. When the transmission rack 703 moves under the push of the connecting rod 706, it drives the transmission rack 707 to move along the length direction of the push rod 701. The transmission rack 707 is integrally formed at one end of the slide groove 702, and its teeth are meshed with the transmission gear 709. The transmission gear 709 is fixedly installed on the rotating shaft 601. Therefore, when the transmission rack 707 moves, it drives the transmission gear 709 to rotate, thereby driving the rotation of the rotating shaft 601 and the clamp assembly 6. The design of the push rod 708 is used to convert the linear motion of the push rod 701 into the rotation of the clamp assembly The opening and closing actions of the component 6, the front end of the push rod 708 extends along the length direction of the push rod 701, and the rear end passes through the rear side wall of the clamp seat 5 and enters the interior of the clamp seat 5. When the push rod 701 moves, the push rod 708 pushes or pulls the clamp assembly 6 to achieve the opening and closing of the clamp. Through the above series of transmission mechanisms, the doctor can control the opening, closing and rotation of the clamp assembly 6 by operating the movable handle 2. This design enables the surgical forceps to flexibly adjust the clamping angle and strength during the operation to adapt to different suturing requirements.

[0071] See also Figure 7 and Figure 8 , the adjustment component 7 also includes,

[0072] A limit platform 710, fixedly connected to an end surface of one side of the first clamp arm 602;

[0073] The position of the limit seat 711 in the rotation direction of the second clamp arm 603 is consistent with the rotation angle of the second clamp arm 603 controlled by the transmission gear 709. The limit seat 711 includes a clamping block at the front end of the rotation direction of the second clamp arm 603, and a limit groove for fixing the limit platform 710 is provided on the clamping block.

[0074] Specifically, the rotation position of the first clamp arm 602 can be limited by the cooperation between the limiting platform 710 and the limiting seat 711 .

[0075] See also Figure 5 and Figure 8 The teeth of the transmission gear 709 are arranged at half of the outer circumference of the transmission gear 709 , and the rotation length of the transmission gear 709 is one quarter of the circumference of the rotating shaft 601 .

[0076] Specifically, the meshing transmission of the transmission rack 707 and the transmission gear 709 can drive the rotating shaft 601 to rotate a certain angle on the clamp seat 5, thereby ensuring that the first clamp arm 602 and the second clamp arm 603 can fit with the surface of the incision tissue, making it convenient for the first clamp arm 602 and the second clamp arm 603 to clamp the incision tissue.

[0077] See also Figure 6 , Figure 7 and Figure 8 , further comprising a suturing assembly 9 disposed on the second clamp arm 603 for suturing the surgical incision, the suturing assembly 9 comprising,

[0078] The needle seat 901 is fixedly mounted on the outer side wall of the second clamp arm 603 and has a needle threading channel;

[0079] A suture needle 902 is slidably mounted on the needle seat 901, and the suture needle 902 is slidably connected to the inside of the needle threading channel;

[0080] The movable roller 903 is rotatably mounted on the top wall of the second clamp arm 603 and is coaxially mounted with the transmission shaft 807;

[0081] The fixed roller 904 is rotatably mounted on the top wall of the second clamp arm 603, and a gap is formed between the fixed roller 904 and the movable roller 903 for the suture to pass through;

[0082] The threading channel 905 is opened through the clamp seat 5 , with its outlet end located at the front end surface of the clamp seat 5 and its inlet end located on the outer wall of the shell 1 .

[0083] Specifically, the suture thread can be passed from the outside into the clamp seat 5 through the threading channel 905, and then passed out of the clamp seat 5. The passed suture thread can be connected to the suture needle 902. After the suture needle 902 is connected to the suture thread, the incision tissue can be squeezed and clamped by the clamp assembly 6 and the squeezing assembly 8. After the incision tissue is squeezed and clamped by the clamp assembly 6 and the squeezing assembly 8, the suture needle 902 can be pushed to slide along the inside of the needle seat 901 so that the suture needle 902 can drive the suture thread to suture the incision tissue.

[0084] The movable roller 903 can rotate along with the second clamp arm 603 , and the suture thread can be driven to feed through the transmission cooperation between the movable roller 903 and the fixed roller 904 , thus achieving the effect of automatic thread feeding.

[0085] See also Figure 4 , Figure 5 and Figure 7 The front end of the push rod 708 is a conical structure, and a return spring 604 is installed between the end handles of the first clamp arm 602 and the second clamp arm 603 to push the first clamp arm 602 and the second clamp arm 603 to move away from each other. The outer wall of the second clamp arm 603 is provided with an inclined surface that is adapted to the push rod 708 to drive the second clamp arm 603 to approach the first clamp arm 602.

[0086] Specifically, the second clamp arm 603 can be pushed toward the first clamp arm 602 by the push rod 708, thereby driving the first clamp arm 602 and the second clamp arm 603 to close and clamp the incision tissue.

[0087] See also Fig. 9 and Fig.10 A hollow cavity is provided inside the first clamp arm 602 and the second clamp arm 603 , and a driving rack 805 is provided inside the hollow cavity. A guide seat 804 is also fixedly installed on the inner bottom wall of the hollow cavity, and the driving rack 805 is slidably connected to the guide seat 804 .

[0088] Specifically, the guide seat 804 can be provided to guide the sliding of the driving rack 805, thereby improving the stability of the driving rack 805 sliding inside the first clamp arm 602 and the second clamp arm 603.

[0089] See also Figure 7 The jaw portion formed between the first clamp arm 602 and the second clamp arm 603 is provided with serrations for clamping and fixing the surgical site.

[0090] Specifically, the clamp assembly 6 is composed of a first clamp arm 602 and a second clamp arm 603, which are connected together at one end by a rotation axis 601, which is not directly mentioned but can be understood as a hinge part of the clamp to form a movable lever system.

[0091] When the doctor applies force to the handle of the forceps, according to the principle of lever, the force will be transmitted to the other end of the first clamp arm 602 and the second clamp arm 603, i.e., the jaw part, through the rotating shaft 601;

[0092] When subjected to force, the first clamp arm 602 and the second clamp arm 603 will rotate relative to the rotating shaft 601, causing the jaws to gradually close. In order to more firmly clamp and fix the surgical site, serrations are specially designed at the jaws. These serrations can increase the friction between the jaws and the surgical site to prevent clamping failure due to sliding or vibration during the operation.
