Description

Technical Field

[0001] The invention relates to medical device technology, and in particular to a hysteroscopic suturing device. Background Art

[0002] Hysteroscopic suturing refers to the process of suturing intrauterine tissues under the assistance of hysteroscopy. During intrauterine suturing, the suturing needle is generally clamped by a needle holder and controlled to penetrate the tissue to achieve suturing of the intrauterine tissues.

[0003] However, in the actual suturing process, since the suture needle is arc-shaped and the operating hole is small, the operating space is limited. Therefore, when suturing, the operator is required to constantly re-clamp the suture needle and rotate the suture device slightly to drive the suture needle to rotate and pass through the tissue, which makes the operation in the suturing process more complicated and difficult, and requires the operator to spend more time and energy.

[0004] Therefore, the present application provides a hysteroscopic suturing device to solve the above problems. Summary of the invention

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] See also Figure 1-Figure 10 A hysteroscopic suturing device comprises a handle bar 1, a catheter 2 and a mounting tube 3, wherein the handle bar 1, the catheter 2 and the mounting tube 3 are fixedly connected in sequence, a through groove is provided at the end of the mounting tube 3, a movable clamp body 4 is rotatably connected to the inner side surface of the through groove, a fixed clamp body 5 corresponding to the movable clamp body 4 is installed at the end of the mounting tube 3, a driving assembly 7 is arranged outside the movable clamp body 4, and the driving assembly 7 is used to drive the movable clamp body 4 to rotate forward or reversely;

[0034] The surfaces of the movable jaw body 4 and the fixed jaw body 5 facing each other are provided with mounting grooves, the inner side surface of the mounting groove on the movable jaw body 4 is rotatably connected to a driven clamping wheel 6, the inner side surface of the mounting groove on the fixed jaw body 5 is rotatably connected to an active clamping wheel 61, the outer surfaces of the driven clamping wheel 6 and the outer surfaces of the active clamping wheel 61 are both provided with a plurality of clamping needle grooves 62 equidistantly in sequence, and a control component 63 is arranged on the outside of the active clamping wheel 61, and the control component 63 is used to control the active clamping wheel 61 to rotate forward or reverse.

[0035] In this embodiment, the driving assembly 7 includes a control shaft 71 that passes through the handle rod 1, the guide tube 2 and the mounting tube 3 in sequence. One end of the control shaft 71 located inside the through groove is rotatably connected to a linkage rod 72. The end of the linkage rod 72 away from the control shaft 71 is rotatably connected to a connecting rod 73. The connecting rod 73 is fixedly connected to the movable clamp body 4.

[0036] Specifically, when the movable jaw body 4 is horizontal, the end of the connecting rod 73 away from the movable jaw body 4 tilts upward, and the end of the linkage rod 72 away from the connecting rod 73 tilts downward. When the control shaft 71 moves toward the end away from the movable jaw body 4, the linkage rod 72 drives the movable jaw body 4 to rotate toward the side away from the fixed jaw body 5.

[0037] In this embodiment, a straight groove 74 is formed inside the end of the handle rod 1 away from the fixed clamp body 5, a baffle 75 is fixedly connected to the outside of the control shaft 71, the baffle 75 is slidably connected to the inner side surface of the straight groove 74, a return spring 76 is fixedly connected between the baffle 75 and the inner wall of the straight groove 74 on the side close to the fixed clamp body 5, and a squeezing ball 77 is fixedly connected to the end of the control shaft 71 away from the fixed clamp body 5.

[0038] It should be noted that when the control shaft 71 is squeezed by external force and moves toward the side close to the fixed clamp body 5, the baffle 75 will move accordingly and compress the return spring 76 in the straight groove 74. When the control shaft 71 moves to this side, under the cooperative squeezing of the linkage rod 72, the end of the connecting rod 73 connected to the linkage rod 72 rotates upward, thereby driving the movable clamp body 4 to rotate downward close to the fixed clamp body 5, so as to clamp and fix the suture needle; when the control shaft 71 is no longer subjected to external force, under the action of the rebound force of the return spring 76, the control shaft 71 moves in the opposite direction and resets, so that under the cooperative traction of the linkage rod 72, the movable clamp body 4 can be driven to rotate toward the end away from the fixed clamp body 5, thereby releasing the clamping of the suture needle.

[0039] In this embodiment, the control component 63 includes a cavity opened inside the fixed clamp body 5, and the inner side surface of the cavity is rotatably connected to a winding wheel 631, which is coaxially arranged with the active clamping wheel 61, and the outer surface of the winding wheel 631 is wound with a control rope 632, and the end of the handle rod 1 away from the fixed clamp body 5 is fixedly connected to a control plate 633, and movable grooves 634 are opened at the upper and lower ends of the side of the control plate 633, and a slide plate 635 is slidably connected to the inner side surface of the movable groove 634, and the surface of the slide plate 635 is fixedly connected to a control block 636, and a connecting spring 637 is fixedly connected between the surface of the slide plate 635 away from the control block 636 and the inner wall of the movable groove 634, and two wiring grooves are opened inside the fixed clamp body 5, which pass through the mounting tube 3, the guide tube 2, and the handle rod 1 in sequence and extend to the inside of the control plate 633, and a notch 638 is opened on the side of the slide plate 635 close to the notch of the wiring groove.

[0040] Specifically, the opening of the wiring groove on the control board 633 is arranged on the inner wall of the movable groove 634 and close to the side of the opening of the movable groove 634 , and the opening of the wiring groove corresponds to the position of the notch 638 .

[0041] It should be noted that the position of the wiring groove slot on the control board 633 is set on the inner wall of the movable groove 634 and close to the side of the movable groove 634 slot, so that when the control block 636 on one side is pressed toward the inside of the movable groove 634, the end of the control rope 632 on this side will move synchronously with the slide plate 635 on this side, so that this end of the control rope 632 can drive the winding wheel 631 to rotate and relax this end of the control rope 632. While this end is being relaxed, the winding wheel 631 rotates to reel in the other end of the control rope 632, so that the other end of the control rope 632 is subjected to traction. At this time, under the guidance of the wiring groove corresponding to the other end of the control rope 632, the control rope 632 at this end can pull the slide plate 635 connected to it to move, and drive the side control block 636 to move outward.

[0042] In this embodiment, the two ends of the control rope 632 pass through two wiring grooves and are fixedly connected to the inner walls of the notches 638 on the two slides 635. The control block 636 on one side moves toward the movable groove 634 to pull the end of the control rope 632 on that side, and drives the winding wheel 631 to rotate to wind and pull the other end of the control rope 632.

[0043] In this embodiment, arc-shaped finger grooves 8 are symmetrically formed at the upper and lower ends of the control plate 633 away from the squeezing ball 77 .

[0044] It should be noted that, during hand-held use, the index finger and the middle finger are placed in the two arc-shaped finger grooves 8 respectively, and the palm is in contact with the surface of the squeezing ball 77, so that when clamping control is performed, the palm position can be adjusted by bending the fingers to achieve the state adjustment of the movable clamp body 4, and in this process, the position of the thumb can be well moved to the position corresponding to the two control blocks 636, so as to facilitate its operation during use.

[0045] During use, the handle bar 1 can be stably held by placing the index finger and the middle finger in the two arc-shaped finger grooves 8 respectively, and the palm of the hand contacts the surface of the squeezing ball 77;

[0046] During the suturing process, the palm position is first adjusted by bending the fingers so that the palm can squeeze the squeezing ball 77 and drive the control shaft 71 to move toward the side close to the fixed clamp body 5. When the control shaft 71 moves toward the side close to the fixed clamp body 5, the baffle 75 will move accordingly and compress the return spring 76 in the straight groove 74. At the same time, when the control shaft 71 moves toward this side, under the cooperative squeezing of the linkage rod 72, the end of the connecting rod 73 connected to the linkage rod 72 can also be driven to rotate upward, so that the movable clamp body 4 can be driven to rotate downward and close to the fixed clamp body 5, so that the driven clamp wheel 6 and the active clamp wheel 61 gradually approach each other, and under the cooperation of the needle clamping groove 62 on the surfaces of both, the suture needle can be stably clamped;

[0047] After the suture needle is clamped, the needle head of the suture needle is placed on the tissue to be punctured, and then the upper control block 636 or the lower control block 636 is pressed by the thumb as needed. When the control block 636 on one side is pressed to move toward the inside of the movable groove 634, the end of the control rope 632 on this side will move synchronously with the slide plate 635 on this side, so that the end of the control rope 632 can drive the winding wheel 631 to rotate and relax the end of the control rope 632. While the end is being relaxed, the rotation of the winding wheel 631 will reel in the other end of the control rope 632, so that the other end of the control rope 632 is subjected to traction. At this time, under the guidance of the wiring groove corresponding to the other end of the control rope 632, the control rope 632 at this end can be pulled The sliding plate 635 connected thereto is pulled to move, and the side control block 636 is driven to move outward, and the winding wheel 631 will drive the active clamping wheel 61 to rotate when rotating, and the active clamping wheel 61 can drive the suture needle to move when rotating. Since the suture needle itself is arc-shaped, when the rotating rod of the active clamping wheel 61 cooperates with the driven clamping wheel 6 to transport it, the suture needle rotates as a whole and can pass through the tissue. After the end of the suture needle passes through the tissue, by reducing the squeezing of the squeezing ball 77 by the palm, the control shaft 71 can move in the reverse direction and reset under the action of the rebound force of the reset spring 76, so that the movable clamp body 4 can be pulled to rotate in the reverse direction and separate from the fixed clamp body 5. At this time, the operator can repeat the above process to clamp the end of the suture needle again;

[0048] After the control shaft 71 is reset in the reverse direction to release the clamp on the suture needle, the operator releases the squeeze on the control block 636, so that under the action of the rebound force of the connecting spring 637, the control block 636 can also move in the reverse direction and reset, to ensure that the suture needle can be moved again by controlling the rotation of the active clamping wheel 61.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
