Description

Technical Field

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

[0002] Traditional needle and thread suturing requires surgeons to operate carefully stitch by stitch, which often leads to prolonged operation time and causes additional pain and discomfort to patients. In addition, the skin and tissues need to be punctured during the suturing process, which may cause additional damage to surrounding tissues and increase surgical trauma. Traditional needle and thread suturing has high tension, and thread knots and needle holes may leave obvious scars, affecting the appearance. Frequent dressing changes and suture removal are required after surgery. This process may increase the risk of bacterial infection and affect wound healing.

[0003] The surgical incision stapler uses the principle of a stapler to hammer titanium staples to anastomose the tissues. The titanium staples are quickly pressed into the tissues on both sides of the incision through a mechanical device to achieve rapid closure of the incision. Titanium staples have good biocompatibility and can remain safely in the body until they are absorbed by the tissue or fall off naturally. Compared with traditional needle and thread suturing, this stapler that uses the principle of a stapler only needs to align the surgical incision and press the firing mechanism to suturing. It is simple to operate and can suture the surgical incision faster, thereby significantly shortening the suturing time and improving the efficiency of the operation.

[0004] However, the existing surgical incision staplers require medical staff to use instruments such as tweezers to perform preliminary alignment of the surgical incision before suturing, and then use the surgical incision staplers to sew to ensure the accuracy and effect of the suturing, which requires additional operations by medical staff, increases the time of the operation, and the use of instruments such as tweezers may cause the incision to be over-closed, and cannot ensure that the force on the tissues on both sides of the surgical incision is uniform, which may cause the surgical incision to contract, pull, widen and proliferate, and the incision marks after postoperative recovery are more obvious. Summary of the invention

[0005] The purpose of the present invention is to provide a surgical incision suturing device to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A surgical incision suturing device comprises a handle, a base, a closing mechanism, a firing mechanism and a propulsion mechanism. The handle is fixedly connected to the base, the closing mechanism is fixedly connected to the base, the firing mechanism and the closing mechanism are slidably connected, the base is provided with a No. 1 mounting groove, the propulsion mechanism is placed in the No. 1 mounting groove, the firing mechanism and the propulsion mechanism are hingedly connected, and the firing mechanism and the base are hingedly connected.

[0007] The operator holds the suturing device through the handle, and aligns the suturing device with the surgical incision through the closing mechanism, and then places one end of the closing mechanism on the surgical incision. The firing mechanism is started, and the closing mechanism closes the surgical incision at the same time. After the surgical incision is closed, the closing mechanism stops working, and the titanium nails emitted by the firing mechanism pass through the skin tissue and are formed and fixed to suture the surgical incision. The next titanium nail is pushed to the firing position through the pushing mechanism, waiting for the next suturing.

[0008] Furthermore, the closing mechanism includes a transmission unit, a stop unit, a guide rail and a slider No. 1. The transmission unit and the firing mechanism are slidably connected, the stop unit and the slider No. 1 are hingedly connected, the stop unit and the base are slidably connected, the guide rail and the base are fixedly connected, two guide rails are provided, four slider No. 1 are provided, the slider No. 1 is slidably connected to the guide rail, and the transmission unit and the slider No. 1 are transmission connected.

[0009] Through the transmission unit, after the firing mechanism is started, the power of the firing mechanism is transmitted to the No. 1 slider, which is then pressed against the tissues on both sides of the surgical incision through four No. 1 sliders. The No. 1 slider slides on the two guide rails, driving the tissues on both sides to move toward the incision line of the surgical incision, thereby closing the surgical incision. After the surgical incision is closed, the connection between the No. 1 slider and the transmission unit is disconnected through the stop unit to prevent the surgical incision from being subjected to excessive tension, thereby avoiding contracture, traction, widening and hyperplasia of the surgical incision.

[0010] Furthermore, the firing mechanism includes a pressure plate, a No. 1 connecting rod, a No. 1 spring and a firing plate. The pressure plate and the base are hinged, the No. 1 connecting rod and the pressure plate are hinged, the pressure plate and the No. 1 spring are fixedly connected, the pressure plate and the firing plate are fixedly connected, the No. 1 spring and the handle are fixedly connected, the No. 1 connecting rod and the propulsion mechanism are hinged, and the pressure plate and the transmission unit are slidably connected.

[0011] By pressing the rear end of the pressure plate, the pressure plate rotates along the hinge with the base, driving the transmission unit to move downward, thereby moving the No. 1 slider on the guide rail to close the surgical incision. At the same time, the pressure plate moves the firing plate downward to knock the titanium nail placed on the No. 1 mounting groove, so that the titanium nail passes through the skin tissue and is formed and fixed, thereby suturing the surgical incision. Through the No. 1 spring, when the rear end of the pressure plate is released, the pressure plate is restored to its initial position to facilitate the next suturing. When the titanium nail needs to be filled, the pressure plate is opened and the propulsion mechanism is driven backward through the No. 1 connecting rod, so that there is enough space in the No. 1 mounting groove to install the titanium nail.

[0012] Furthermore, the transmission unit includes an L-shaped connecting rod, a No. 2 spring, a No. 2 connecting rod, a guide rod and a clamping block. The pressure plate is provided with a No. 1 sliding groove. Two L-shaped connecting rods are provided. The L-shaped connecting rod is slidably connected to the No. 1 sliding groove. The No. 2 spring is placed in the No. 1 sliding groove. The No. 2 spring is fixedly connected to the L-shaped connecting rod. Two No. 2 connecting rods are provided. The No. 2 connecting rod is hinged to the L-shaped connecting rod. The guide rod is fixedly connected to the base. The guide rod is provided with a guide groove. The No. 2 connecting rod is slidably connected to the guide groove. The clamping block is fixedly connected to the No. 2 connecting rod, and the clamping block is in conflict with the stop unit.

[0013] Through the guide groove set by the guide rod, the No. 2 connecting rod can only slide in the guide groove, so that the L-shaped connecting rod can only move vertically downward. Through the No. 1 sliding groove, when the L-shaped connecting rod moves under the drive of the pressure plate, the L-shaped connecting rod moves into the No. 1 sliding groove, so that the L-shaped connecting rod keeps moving vertically downward in a straight line. The No. 2 connecting rod and the L-shaped connecting rod are hingedly connected, so that the No. 2 connecting rod slides into the guide groove, and through the interference of the block and the stop unit, it drives the No. 1 slider to move toward the incision line. After suturing is completed, when the pressure plate returns to its initial position, the No. 2 spring can enable the L-shaped connecting rod to return to its initial position.

[0014] Furthermore, the stop unit includes a slide rod No. 1, a connecting rod No. 3, a connecting block No. 1, a connecting rod No. 4, a connecting block No. 2 and a slider No. 2. The slide rod No. 1 is provided with two, the slide rod No. 1 is fixedly connected to the base, the base is provided with a No. 2 sliding groove, the connecting rod No. 3 is provided with two, the connecting rod No. 3 is slidably connected to the No. 2 sliding groove, the connecting rod No. 3 is slidably connected to the connecting block No. 1, the connecting block No. 1 is provided with two, the connecting rod No. 4 is provided with four, the connecting rod No. 4 is hinged to the connecting block No. 1, the connecting block No. 2 is provided with a guide surface, the connecting block No. 2 is slidably connected to the slide rod No. 1, the slide rod No. 2 is fixedly connected to the No. 2 connecting block, the No. 2 slide rod is slidably connected to the No. 1 slide block, the No. 2 connecting block is in conflict with the card block, the base is provided with a No. 3 sliding groove, the slide rod No. 1 is slidably connected to the No. 3 sliding groove, the slide rod No. 1 is provided with a No. 4 sliding groove, and the connecting rod No. 3 is slidably connected to the No. 4 sliding groove.

[0015] When slider No. 1 drives the surgical incision to close, the inner wall of the incision squeezes slider No. 1, the tail end of slider No. 1 is spherical, and the inner wall of the incision only contacts the tail end, so that slider No. 1 slides upward when squeezed, thereby making connecting rod No. 3 connected to it move upward, and making connecting rod No. 3 drive connecting block No. 1 to move upward, through connecting rod No. 4 and connecting block No. 1 hinge connection, connecting rod No. 4 and connecting block No. 2 hinge connection, thereby driving connecting block No. 2 to move, through connecting block No. 2 and slider No. 2 fixed connection, slider No. 2 and slider No. 1 sliding connection, make connecting block No. 2 and slider No. 2 slide on slider No. 1, thereby making the conflict between connecting block No. 2 and card block disconnect, so that card block can no longer push connecting block No. 2 to move, thereby stopping slider No. 1, through two slider No. 1, due to different tissue composition on both sides, it is subjected to different pressure, and the rising time of two slider No. 1 is finely controlled, thereby respectively controlling The two No. 3 connecting rods enable the No. 1 sliders on both sides to stop respectively as they are squeezed, so that the surgical incision can be closed to the incision line, which is beneficial to the uniform force on the tissues on both sides of the surgical incision. Through the four No. 4 connecting rods, one No. 3 connecting rod can control the two No. 1 sliders, thereby controlling the four No. 1 sliders. A guide surface is provided through the No. 2 connecting block, so that when the pressure plate is released, the card block can push the No. 2 connecting block back to the initial position, and the guide surface is an inclined surface, so that the card block can transition to the initial position. When the No. 1 slider is not squeezed by the two sides at the same time, the side that touches the No. 1 slider first pushes the two No. 1 sliders to slide in the same direction in the No. 3 sliding groove, and through the No. 4 sliding groove, the No. 3 connecting rod is not affected by the left and right movement of the No. 1 slider, and a small adjustment is made to move the No. 1 slider to the incision line until the two No. 1 sliders are squeezed at the same time, ensuring that the incision can be accurately closed and the tissues on both sides are uniformly stressed.

[0016] Furthermore, the No. 1 slider includes an outer shell, a No. 3 spring and a No. 3 slider. The outer shell is provided with a No. 5 sliding groove, which is slidably connected to the guide rail. The outer shell is provided with a No. 2 mounting groove, in which the No. 3 spring is placed. The No. 3 slider is fixedly connected to the No. 3 spring. The No. 2 mounting groove is slidably connected to the No. 3 slider. The outer shell is provided with a No. 6 sliding groove, in which the No. 2 slider is slidably connected to the No. 6 sliding groove. The bottom surface of the No. 3 slider is provided with a friction surface.

[0017] Through the No. 6 sliding groove and the No. 5 sliding groove, the No. 2 slider can drive the shell to slide back and forth on the guide rail, and through the No. 3 slider, it can slide into the No. 2 installation groove. When the tissues on both sides of the surgical incision are uneven, adjustments can be made to keep the suturing device and the surgical incision level. Through the No. 3 spring, when the suturing device is lifted, the No. 3 slider can return to its initial position. The friction surface is provided on the bottom of the No. 3 slider, so that the No. 3 slider can drive the tissues on both sides of the incision to move toward the incision line, and when the tissues on both sides of the incision stop, they will not retreat due to the reaction force of the tension, thereby preventing the merged incision from loosening again.

[0018] Furthermore, the base is provided with a forming groove, and the firing plate is convex.

[0019] Through the forming groove, the titanium nail can pass through the skin tissue at a certain inclination angle, so that the tissues on both sides of the incision will not loosen due to the force of the titanium nail. The firing plate is convex, so that the titanium nail can be recessed towards the skin surface after suturing and fixation, preventing the surgical incision from being over-closed.

[0020] Furthermore, the propulsion mechanism includes a No. 2 slide bar, a No. 4 slider and a No. 4 spring. The No. 2 slide bar is placed in the No. 1 mounting groove. The No. 2 slide bar and the No. 4 slider are slidably connected. The No. 4 spring is sleeved outside the No. 2 slide bar. The No. 4 spring and the No. 4 slider are fixedly connected. The No. 4 slider and the No. 1 connecting rod are hingedly connected.

[0021] Through the No. 2 slide bar, the No. 4 slide block can slide horizontally in the No. 1 installation groove. Through the No. 4 spring, after the front titanium nail is used, the rear titanium nail can be pushed to the firing position by the No. 4 slide block. The No. 4 slide block and the No. 1 connecting rod are hingedly connected, so that when the pressure plate is opened, it can drive the No. 4 slide block to slide backward, which is convenient for loading new titanium nails.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the closing mechanism, the surgical incision stapler can automatically perform preliminary closure of the surgical incision before suturing, thereby eliminating the need to use instruments such as tweezers to assist in the preliminary closure of the surgical incision, reducing the operating steps of medical staff, simplifying the operating process, reducing the time of the operation, and thus improving the efficiency of the operation.

[0023] 2. The No. 1 slide bar of the closing mechanism can adjust itself to the incision line position along with the tissues on both sides of the surgical incision. The two No. 1 slide bars make the tissues on both sides subject to different pressures due to their different compositions. The rising time of the two No. 1 slide bars is finely controlled to make the side that rises later move a little more toward the other side and make fine adjustments. Through double adjustments, the surgical incision can be accurately closed on the incision line, ensuring that the force on both sides of the surgical incision is even, avoiding contracture, traction, widening and hyperplasia of the surgical incision, and making the incision mark after postoperative recovery shallower.

[0024] 3. Through the forming groove, the titanium nail can pass through the skin tissue at a certain inclination angle, so that the tissues on both sides of the incision will not loosen due to the force of the titanium nail. The firing plate is convex, so that the titanium nail can be recessed toward the skin surface after suturing and fixation, preventing the surgical incision from over-closing, avoiding contracture, traction, widening and hyperplasia of the surgical incision, and making the incision mark after postoperative recovery shallower.

[0025] 4. The No. 3 slider can slide into the No. 2 mounting groove. When the tissues on both sides of the surgical incision are uneven, it can be adjusted to keep the suturing device and the surgical incision level, so that when the surgical incision is closed, the force on the tissues on both sides of the surgical incision is even.

After the surgical incision is closed, the closing mechanism 3 stops working, and the titanium nails emitted by the firing mechanism 4 pass through the skin tissue and are formed and fixed to suturing the surgical incision. The next titanium nail is pushed to the firing position through the pushing mechanism 5, waiting for the next suturing.

[0031] like Figure 1~Figure 3 As shown, the closing mechanism 3 includes a transmission unit 31, a stop unit 32, a guide rail 33 and a slider 34.

[0034] By pressing the rear end of the pressure plate 41, the pressure plate 41 rotates along the hinge with the base 2, driving the transmission unit 31 to move downward, thereby moving the No. 1 slider 34 on the guide rail 33 to close the surgical incision. At the same time, the pressure plate 41 moves the firing plate 44 downward to knock the titanium nail placed on the No. 1 mounting groove 21, so that the titanium nail passes through the skin tissue and is formed and fixed, thereby suturing the surgical incision. Through the No. 1 spring 43, when the rear end of the pressure plate 41 is released, the pressure plate 41 is restored to the initial position to facilitate the next suturing. When the titanium nail needs to be filled, the pressure plate 41 is opened, and the No. 1 connecting rod 42 is used to drive the propulsion mechanism 5 to retreat, so that the No. 1 mounting groove 21 has enough space to install the titanium nail.

[0036] By means of the guide groove 3141 provided on the guide rod 314, the No. 2 connecting rod 313 can only slide in the guide groove 3141, so that the L-shaped connecting rod 311 can only move vertically downward. By means of the No. 1 sliding groove 411, when the L-shaped connecting rod 311 moves driven by the pressure plate 41, the L-shaped connecting rod 311 moves into the No. 1 sliding groove 411, so that the L-shaped connecting rod 311 keeps moving vertically downward in a straight line.

The guide surface is an inclined surface, so that the block 315 can transition to the initial position. When the two sides do not squeeze the No. 1 slide bar 321 at the same time, one side of the No. 1 slide bar 321 is touched first to push the two No. 1 slide bars 321 to slide in the same direction in the No. 3 slide groove 23. Through the No. 4 slide groove 3211, the No. 3 connecting rod 322 is not affected by the left and right movement of the No. 1 slide bar 321. A small adjustment is made to move the No. 1 slide bar 321 to the incision line until the two No. 1 slide bars 321 are squeezed at the same time to ensure that the incision can be accurately closed and the tissues on both sides are evenly stressed.

The No. 3 slider 343 and the No. 3 spring 342 are fixedly connected, and the No. 2 mounting groove 3411 and the No. 3 slider 343 are slidably connected. The shell 341 is provided with a No. 6 sliding groove 3412, and the No. 2 slider 326 and the No. 6 sliding groove 3412 are slidably connected. The bottom surface of the No. 3 slider 343 is provided with a friction surface.

[0040] Through the No. 6 sliding groove 3412 and the No. 5 sliding groove, the No. 2 slider 326 can drive the shell 341 to slide back and forth on the guide rail 33, and through the No. 3 slider 343, it can slide into the No. 2 mounting groove 3411. When the tissues on both sides of the surgical incision are uneven, adjustments can be made to keep the suturing device and the surgical incision level. Through the No. 3 spring 342, when the suturing device is lifted, the No. 3 slider 343 can return to its initial position. The friction surface is provided on the bottom surface of the No. 3 slider 343, so that the No. 3 slider 343 can drive the tissues on both sides of the incision to move toward the incision line, and when the tissues on both sides of the incision stop, they will not retreat due to the reaction force of the tension, thereby preventing the merged incision from loosening again.

[0041] like Figure 4 As shown, the base 2 is provided with a forming groove 24, and the firing plate 44 is convex.

[0042] The forming groove 24 allows the titanium nail to pass through the skin tissue at a certain tilt angle so that the tissues on both sides of the incision will not loosen due to the force of the titanium nail. The firing plate 44 is convex so that the titanium nail can be recessed toward the skin surface after suturing and fixing, thereby preventing the surgical incision from being over-closed.

[0043] like Fig.10 and Fig.11 As shown, the propulsion mechanism 5 includes a No. 2 slide bar 51, a No. 4 slider 52 and a No. 4 spring 53. The No. 2 slide bar 51 is placed in the No. 1 mounting groove 21. The No. 2 slide bar 51 and the No. 4 slider 52 are slidably connected. The No. 4 spring 53 is sleeved outside the No. 2 slide bar 51. The No. 4 spring 53 and the No. 4 slider 52 are fixedly connected. The No. 4 slider 52 and the No. 1 connecting rod 42 are hingedly connected.

[0044] Through the No. 2 slide bar 51, the No. 4 slide block 52 can slide horizontally in the No. 1 installation groove 21. Through the No. 4 spring 53, after the front titanium nail is used, the rear titanium nail can be pushed to the firing position by the No. 4 slide block 52. The No. 4 slide block 52 and the No. 1 connecting rod 42 are hingedly connected, so that when the pressure plate 41 is opened, it can drive the No. 4 slide block 52 to slide backward, which is convenient for loading new titanium nails.

[0045] Working principle: by placing one end of the suturing device closing mechanism 3 on the surgical incision, the No. 1 slider 34 is in conflict with the tissues on both sides of the incision, and by pressing the pressure plate 41, the L-shaped connecting rod 311 moves downward, thereby driving the No. 2 connecting rod 313 to slide into the guide groove 3141, so that the block 315 pushes the No. 2 connecting block 325, so that the No. 1 slider 34 moves toward the surgical incision line, and the friction surface is provided on the bottom surface of the No. 3 slider 343, so that the No. 3 slider 343 can drive the tissues on both sides of the incision to move toward the incision line. When the tissues on either side touch the tail end of the No. 1 slider 321, the incision continues to close, so that the inner wall of the incision squeezes the No. 1 slider 321, so that the No. 1 slider 321 slides upward, the No. 3 connecting rod 322 is lifted, and the No. 4 connecting rod 324 is connected by hinges at both ends, so that the No. 2 connecting block 325 moves toward the direction of the No. 3 connecting rod 322 under the action of the No. 2 slider 326. The clamping block 315 and the second connecting block 325 are disconnected from each other, so that the No. 1 slider 34 stops moving. When the incision is closed, all No. 1 sliders 34 stop. Through the forming groove 24, the titanium nail can pass through the skin tissue at a certain tilt angle, so that the tissues on both sides of the incision will not be loosened due to the force of the titanium nail. The firing plate 44 is convex, so that the titanium nail can be recessed toward the skin surface after suturing and fixing, thereby preventing the surgical incision from being over-closed and achieving the suturing of the surgical incision. The suturing device is lifted, and the No. 1 slide bar 321 slides downward, thereby the No. 3 connecting rod 322 moves downward, and the No. 2 connecting block 325 is restored to its initial position. The pressing plate 41 is released, and the L-shaped connecting rod 311 moves upward, thereby driving the No. 2 connecting rod 313 to slide outward of the guide groove 3141, so that the clamping block 315 pushes the No. 2 connecting block 325 to restore its initial position, thereby restoring the No. 1 slider 34 to its initial position.
