Description

Technical Field

[0001] This invention relates to the field of medical instrument technology, specifically to an instrument suitable for vaginal stump suturing under transvaginal or laparoscopic conditions. Background Technology

[0002] In total hysterectomy, with the development of laparoscopic technology, laparoscopic total hysterectomy has gradually become one of the mainstream surgeries for hysterectomy. Furthermore, to meet women's aesthetic needs, single-port laparoscopic total hysterectomy via the umbilicus or vagina is increasingly used clinically. This usually requires the use of long-handled laparoscopic instruments via the laparoscope or a long-handled needle holder via the vagina for vaginal stump suturing, or direct suturing in open surgery. Rapid suturing of the vaginal mucosa can effectively reduce bleeding, close the abdominal cavity earlier, shorten the operation time, and reduce the risk of infection and bleeding. Current suturing techniques often require the use of a needle holder and vascular clamps for needle insertion and suture fixation due to the congestion and narrowness of the vaginal stump. Vaginal suturing is even more difficult, requiring more traction of the vaginal wall for exposure, increasing the risk of tearing and damage to the patient's pelvic floor function. Additionally, in single-port laparoscopic surgery, the current laparoscopic instruments, due to their delicate handling and close proximity of the instrument tips, are more prone to collision during vaginal suturing, causing numerous inconveniences, prolonging suturing time, and significantly reducing surgical efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a vaginal suture-assisted device [CN202122980739.1], which includes a base, an expansion assembly, and a blood-absorbing fabric. The blood-absorbing fabric is placed on top of the base to absorb blood in the vagina. The expansion assembly includes at least three support rods, one end of which is hinged to the bottom of the base, forming an operating space for suture operations between the support rods. It also includes a support plate movably disposed between the support rods, which adjusts the size of the operating space by changing the distance between itself and the base.

[0004] The above solution addresses the problem of existing suturing instruments being unable to perform vaginal suturing to some extent. However, it still has many shortcomings, such as the instruments being prone to collision during suturing, inconvenient operation, and the support rods adding additional obstruction to the field of vision.

[0005] Prolonged suturing time reduces surgical efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a vaginal stump suturing device suitable for transvaginal or laparoscopic procedures.

[0036] The electric assembly clamp 3 controls the number of times the upper clamping component 4 is pressed down, thereby manually controlling the suture length. Next, the suture workpiece positioning device 6 loads the suture workpiece 7. When the upper clamping component 4 drives the vertical suture pressing component 9 to press down elastically, the two ends of the suture workpiece 7 pass through the skin and are inserted into the locking workpiece 8 on the other side of the skin, thereby achieving double locking suture.

[0037] In detail, the telescopic connecting mechanism 2 includes a telescopic sleeve 21 connected to the electric assembly chuck 3. The telescopic sleeve 21 is provided with a telescopic connecting rod 22, and the telescopic connecting rod 22 is provided with at least one adjusting groove 23 axially on its outer circumferential wall.

[0044] The workpiece pressing structure 93 includes a positioning base 931, with pressing parts 932 at both ends corresponding to the sewn workpiece 7, and elastic pressing parts 933 connected between the pressing parts 932.

[0045] After the top pressure part 932 is inserted, the top pressure slot 72 applies pressure, causing the puncture suture part 73 to pass through the skin and connect with the locking workpiece 8. The elastic suture band 74 applies suture and locks the workpiece. When the return spring 94 is pulled out and the lower telescopic rod 92 is lowered, the top pressure part 932 drives the detachable top pressure head 71 to be pulled out. After being pulled out, the top pressure head 71 falls onto the horizontal connecting part 63.

[0046] like Figure 4 As shown, the sewn workpiece 7 includes a detachable top pressure head 71 corresponding to the top pressure part 932. The upper end of the detachable top pressure head 71 is provided with a top pressure slot 72 and the lower end is connected to a puncture suture part 73. The puncture suture parts 73 are connected by an elastic suture band 74, and the detachable top pressure head 71 has a strip-shaped clearance groove through which the elastic suture band 74 can pass.

[0047] like Figure 5 As shown, the sewing workpiece positioning device 6 includes a workpiece sliding positioning frame 61. One end of the workpiece sliding positioning frame 61 has a workpiece receiving part 62, and the other end of the workpiece sliding positioning frame 61 has a horizontal connecting part 63. The upper side of one end of the workpiece receiving part 62 is closed by a sealing cover plate 64, and the end of the sealing cover plate 64 away from the horizontal connecting part 63 is provided with a linkage part 65 that is inclined upward. The linkage part 65 has a linkage insertion hole 66. An inclined dropping part 67 is provided between the workpiece receiving part 62 and one end of the horizontal connecting part 63. The inner circumference of the workpiece sliding positioning frame 61 is provided with a workpiece sliding structure 68.

[0048] The sewn workpiece 7 falls from the feed channel 685 into the workpiece receiving part 62. When the workpiece sliding positioning frame 61 rotates and is tilted, the sewn workpiece 7 slides along the workpiece sliding structure 68 into the positioning groove 683.

[0049] The workpiece sliding structure 68 includes a workpiece waiting groove 681 provided on the workpiece receiving part 62, a dropping groove 682 provided on the dropping part 67 that communicates with the workpiece waiting groove 681, and a positioning groove 683 provided on the horizontal connecting part 63 that communicates with the dropping groove 682. The ends of the positioning groove 683 are connected by a stitching clearance gap 684. The electric assembly chuck 3 is provided with a feeding channel 685 that communicates with the workpiece waiting groove 681.

[0050] like Figure 6As shown, the sewing positioning platform mechanism 5 includes a sewing positioning platform 51 corresponding to the sewing workpiece positioning device 6. The sewing positioning platform 51 is provided with a corresponding workpiece slide groove 52, and the aforementioned locking workpiece 8 is disposed in the workpiece slide groove 52.

[0052] The model and specifications of locking workpiece 52 and suture workpiece 7 can be changed according to the thickness and material requirements of clinical sutures.

[0053] In summary, the principle of this embodiment is as follows: the number of stitches is adjusted by rotating the adjustment switch 35, the micro motor controls the rotating pressure rod 41 to press down, the workpiece pressing structure 93 presses against the stitching workpiece 7, so that the puncture stitching part 73 is inserted into the locking workpiece 8, and the elastic stitching tape 74 is pressed tight. When the return spring 94 is pulled out to lower the telescopic rod 92, the pressing part 932 drives the detachable pressing head 71 to be pulled out. After being pulled out, the pressing head 71 falls onto the horizontal connecting part 63, and the grip handle 1 is moved to perform the second stitching.

[0054] The suturing method in this application involves suturing once, separating and suturing again, using non-continuous suturing, and using electric suturing. After determining the suturing gap, electric secondary suturing is performed, and the suturing density can be controlled as needed.

[0055] Furthermore, this device can be placed in a disinfection equipment for disinfection during the disinfection process, enabling reuse and saving costs.
