Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a deep tissue suture device that is easy to use. Background Art

[0002] In gynecological and pelvic floor reconstruction surgeries, it is often necessary to precisely suture deep fascia tissues, especially when dealing with complex anatomical structures such as feeling the ischial spine and finding the sacrospinous ligament through the vaginal approach. The sacrospinous ligament, as an important part of the pelvic floor structure, its suture is of great significance for restoring pelvic floor function, improving urinary incontinence, and pelvic organ prolapse. However, due to these tissues being deep within the body, the surgical field of view is limited, and coupled with the narrow operating space, traditional suture techniques face many challenges.

[0003] Traditional deep tissue suture methods mainly rely on the doctor's manual operation, which not only requires the doctor to have excellent surgical skills but also long-term surgical experience accumulation. Even so, due to factors such as unclear vision and inconvenient operation, the suture of deep tissues often takes a long time, and the suture quality is difficult to guarantee. In addition, the suture of deep tissues is also prone to complications such as bleeding and infection, increasing the surgical risk and the patient's recovery time.

[0004] In view of this, the present invention proposes a brand-new deep tissue suture device, aiming to solve the technical problems in the deep tissue suture process. This suture device adopts a special design, which can conveniently feel the ischial spine through the vagina and accurately find the sacrospinous ligament for suture, reducing the operation time and bringing better treatment effects and faster recovery time for patients. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides the following technical solutions:

[0006] A deep tissue suture device that is easy to use, including a holding component, a suture, a suture rod, and a suture needle rod. The suture rod and the suture needle rod are cross-rotationally connected; a suture needle is provided at the front end of the suture needle rod, and a groove is opened on the suture needle; a suture groove is opened on the outer side of the front end of the suture rod, and a thread-passing block is slidably arranged inside the front end of the suture rod. The suture passes through both sides of the thread-passing block and lies horizontally outside the suture groove; a control rod is slidably arranged inside the suture rod; by rotating the suture rod and the suture needle rod, the control rod is driven to slide to drive the thread-passing block to slide, driving the suture to approach or move away from the inner wall of the suture groove.

[0007] Further, the suture needle rod is rotationally connected to the suture rod through a fixed rotating shaft, a tooth groove is opened on the rotating shaft, a rack that cooperates with the tooth groove is provided at the tail end of the control rod, an inclined groove is opened at the front end of the control rod, and a convex block that cooperates with the inclined groove is fixedly arranged on the thread-passing block.

[0008] Further, the rear end of the thread passing block is connected to the suture rod through an elastic element. Under the action of the elastic element, the thread passing block has a tendency to slide inward towards the suture rod. By rotating to close the suture rod and the suture needle rod, the suture needle is inserted into the suture groove. At the same time, the rack of the control rod slides backward under the action of the rotating shaft. Under the action of the elastic element, the convex block of the thread passing block slides into the inclined groove, driving the suture to move towards the inner wall of the suture groove and enter the groove of the suture needle.

[0009] By rotating to open the suture rod and the suture needle rod, the rack of the control rod slides forward under the action of the rotating shaft, pushing the convex block of the thread passing block out of the inclined groove, driving the suture to move towards the outside of the suture groove. At the same time, the suture needle is lifted, and the suture is hooked and lifted through the groove.

[0010] Further, the opening direction of the groove deviates from the tip of the suture needle and is inclined towards the outside of the suture groove.

[0011] Further, L-shaped thread passing cylinders are fixedly arranged on both sides of the thread passing block, and the suture passes through the two L-shaped thread passing cylinders in sequence.

[0012] Further, the holding member includes a holding rod, two handles, and a pull rope. The two handles are rotatably connected together, and one handle is fixedly installed at the tail end of the holding rod. The front end of the holding rod is rotatably connected to the suture rod and the suture needle rod coaxially. A control block with a gradually decreasing head end is slidably arranged inside the front end of the holding rod. Connecting grooves are opened at the tail ends of the suture rod and the suture needle rod. The front end of the control block slides along the connecting groove, and the rear end of the control block is connected to the holding rod through an elastic element. The pull rope is located inside the holding rod. The front end of the pull rope is connected to the control block, and the rear end is connected to the handle that is not fixedly connected to the holding rod. By rotating to close the two handles, the pull rope is pulled to pull the control block backward, driving the tail ends of the suture rod and the suture needle rod to rotate towards each other, so that the front ends of the suture rod and the suture needle rod rotate and close.

[0013] Further, a winding disc is rotatably arranged on the holding rod, and the suture is wound around the winding disc.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] A deep tissue suture device that is easy to use designed by the present invention is provided with a suture needle at the front end of the suture needle rod, a suture groove is opened on the outer side of the front end of the suture rod, and a thread passing block is slidably arranged inside the front end of the suture rod. The suture passes through the L-shaped thread passing cylinders on both sides of the thread passing block.

[0016] When in use, by rotating and closing the two handles, pulling the pull rope to pull the control block backwards, the tail ends of the suture rod and the suture needle rod are driven to rotate toward each other, so that the front ends of the suture rod and the suture needle rod are rotated and closed, clamping the fascia tissue, so that the suture needle passes through the fascia tissue and is inserted into the suture groove, and at the same time, the rack of the control rod slides backwards under the action of the rotating shaft, and the convex block of the thread block slides into the bottom of the inclined groove under the action of the elastic element, driving the suture thread to move toward the inner wall of the suture groove and enter the groove of the suture needle;

[0017] Then, by turning the two handles, the suture rod and the suture needle rod are turned open, so that the rack of the control rod slides forward under the action of the rotating shaft, and the protrusion of the thread passing block is pushed out of the inclined groove, driving the suture thread to move to the outside of the suture groove. At the same time, the suture needle is lifted up, and the suture needle is hung on the suture thread through the groove, driving the suture thread to move up and pass through the fascia tissue with the suture needle, thereby facilitating suturing. The design of the suture rod and the suture needle rod facilitates operation in deep tissues. BRIEF DESCRIPTION OF THE DRAWINGS
