Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a postpartum uterine compression suture and removal structure. BACKGROUND

[0002] The statements herein are provided only to enhance understanding of the present application and do not necessarily constitute prior art.

[0003] Postpartum hemorrhage (PPH) is the most important cause of maternal death, and more than 1 / 4 of maternal deaths worldwide are caused by PPH. Previous treatment options for PPH include conservative treatment and surgical treatment, the latter mainly refers to blood vessel ligation and hysterectomy.

[0004] Conservative treatment methods include the application of uterine contraction agents, uterine massage, intrauterine gauze or balloon tamponade, etc. Some patients have poor response to conservative treatment, especially those who have given birth to a large baby, or have multiple pregnancies, are complicated by polyhydramnios, placenta previa, placenta implantation, etc. The uterine incision and placental separation surface still continue to bleed, and the effect of conservative treatment on patients with poor effect is poor, and then invasive treatment methods such as uterine artery ligation and internal iliac artery ligation are used. The blood vessels supplying the uterus during pregnancy are highly dilated and form a dense communication branch and vascular network with the surrounding blood vessels. Especially in patients with placenta implantation disease, a large number of heteroplastic and bridging blood vessels are formed between the surrounding tissues, organs and uterus, and the effect of local blood vessel ligation is still limited. When the bleeding cannot be controlled, hysterectomy is used as the last treatment. Although hysterectomy can be used as an effective treatment method to save lives in emergency situations, the patient will lose the ability to reproduce, and at the same time, a huge psychological trauma will be formed.

[0005] In the past 30 years, the effectiveness of uterine compression suture in the treatment of postpartum hemorrhage and prevention of hysterectomy has been fully confirmed. Since the B-Lynch suture was first reported in 1997, a variety of modified uterine compression suture techniques have been reported and applied to different postpartum hemorrhage treatment scenarios, such as Cho suture, Hyman suture and MY suture, etc. The above uterine compression suture techniques make the anterior and posterior walls of the uterus closely adhere to each other by square suture, thereby compressing the blood sinus to stop bleeding. However, the above suture methods have two common characteristics: (1) part of the suture line runs in the uterine cavity; (2) the suture line cannot be removed. These two characteristics bring certain side effects to the patient. Specifically, the suture line compresses the uterine muscle layer for a long time, leading to blood supply obstruction and muscle necrosis, and the uterine muscle layer becomes thin. The anterior and posterior walls of the uterine cavity are adhered to each other under long-term compression and suture stimulation, and the endometrial cells are ischemic, necrotic, inflammatory and fibrotic, the endometrial receptivity is decreased, and the fertilized egg cannot implant, etc. These side effects can cause various complications in patients.

[0006] If the suture line compressing the uterine muscle layer can be removed in time, the compression of the uterus is released, and the normal blood supply of the uterus is restored, the endometrial receptivity of the female can be effectively improved, the risk of uterine muscle injury and intrauterine adhesion is reduced, the risk of uterine muscle injury and intrauterine adhesion is reduced, and the probability of fertilized egg is improved. The existing suture line removal related instrument is provided with a reset spring and a drag hook in the elbow, and the suture line is pulled back to realize removal. The reset spring ensures the flexibility of operation.

[0007] The existing suture line remover has the following technical problems: (1) The doctor holds the line removing scissors by hand, then stretches the line removing scissors into the uterus, after the line removing scissors are stretched in, the line removing condition cannot be observed any more, and the stretching process may cause damage of the line removing scissors to the vaginal lateral wall, uterine mucosa and muscle layer, and the discomfort caused by the stretching process of the line removing scissors makes the patient have a resistance psychology.

[0008] (2) After uterine compression suture is performed, the uterus is surrounded by the suture line, because the uterine contraction time of different patients is different, the doctor removes the line according to the general time, the line is removed too early to affect the recovery effect, the line is removed too late to cause infection of the suture line, and there is no basis for judging the removal time of the suture line. SUMMARY

[0009] The purpose of the present application is to provide a postpartum uterine compression suture line removing structure which can at least solve one of the above technical problems.

[0010] In order to achieve the above purpose, the present application provides a postpartum uterine compression suture line removing structure, which comprises a hollow sphere, a blade is fixedly arranged in the hollow sphere, a sheath is arranged at the bottom of the blade, a suture line is arranged below the sheath, the suture line penetrates the hollow sphere, a sheath tube is fixedly connected to the bottom of the hollow sphere, a first pull wire is fixedly connected to the bottom of the sheath, the first pull wire extends into the sheath tube, a second pull wire is connected to the middle of the suture line, the second pull wire extends into the sheath tube, and a scale line is arranged on the second pull wire.

[0011] Further, a pin shaft is arranged on one side of the blade, the sheath is sleeved on the pin shaft, and the sheath is arranged in an L shape.

[0012] Further, the pin shaft is connected with the first pull wire through a pin shaft line.

[0013] Further, the blade is arranged in the middle of the inner side wall of the hollow sphere.

[0018] Further, the first pull line and the second pull line are provided with different colors.

[0019] Further, the circular hole corresponds to the suture and is provided with a ball groove upwardly.

[0020] The beneficial effects of one or more of the above technical solutions are: (1) When the suture is removed, the first pull line is pulled outside the vaginal orifice to drive the sheath to separate from the blade along the arc-shaped protrusion, at this time, the sheath is left in the hollow sphere, the sheath tube is pulled outside the vaginal orifice to drive the sphere to move downward, at this time, the blade is driven to cut the suture downward, the suture is cut, the sphere is pulled out by pulling the sheath tube downward, the whole process does not need to use scissors, and the suture structure is implanted during the suture process, and the suture can be removed through the first pull line and the second pull line.

[0021] (2) With the lapse of the rehabilitation time, the second pull line will be loose, at this time, the second pull line will move downward, the length change can be observed by observing the scale of the second pull line extending outside the vaginal orifice, so that whether the suture can be removed can be judged.

[0026] The specific implementation of the present embodiment will be described below with reference to the drawings.

[0027] Embodiment 1 The present application provides a postpartum uterine compression suture removal structure, which is referred to Figure 1 and Figure 2, including a hollow sphere 1, a blade 2 fixedly arranged in the hollow sphere 1, a sheath 3 arranged at the bottom of the blade 2, a suture 4 arranged below the sheath 3, the suture 4 penetrating through the hollow sphere 1, a sheath tube 9 fixedly connected to the bottom of the first hollow sphere 1, a first pull wire 5 fixedly connected to the bottom of the sheath 3 and extending into the sheath tube 9, a second pull wire 6 connected to the middle of the suture 4 and extending into the sheath tube 9, and a scale line 10 arranged on the second pull wire 6.

[0028] The blade 2 is provided with a pin shaft 8 on one side, the pin shaft 8 is sleeved with the sheath 3, the sheath 3 is arranged in an L shape, the L-shaped sheath 3 is rotated to open and close through the pin shaft 8, the blade 2 is completely wrapped before cutting is ensured, and the L-shaped structure provides a lever fulcrum, so that the first pull wire 5 can efficiently separate the sheath 3 from the blade 2 when being pulled.

[0029] The pin shaft 8 is connected with the first pull wire 5 through a connecting line 51, the first pull wire 5 is pulled outside the vaginal orifice, the connecting line transmits force, the pin shaft 8 rotates, and the sheath 3 is separated, so that the "in-vivo operation triggers in-vitro cutting" is realized, and the traditional instrument invasion is avoided.

[0030] The blade 2 is arranged on the inner wall of the hollow sphere 1 in the middle, the middle arrangement makes the blade 2 bear force evenly when cutting downward, avoids the cutting being incomplete or the surrounding tissue being damaged due to deflection, and ensures that the blade 2 and the suture 4 penetrating through the sphere are in the best cutting position.

[0031] Round holes 7 are arranged on both sides of the hollow sphere 1, the suture 4 penetrates through the round holes 7, and when the suture 4 is relaxed during the recovery period, the suture 4 can slide along the ball groove 71, the relaxation degree can be intuitively reflected by observing the relative scale displacement of the second pull wire 6 and the sheath tube 9 (for example, the scale displacement of 3 cm indicates that the suture can be removed), and the design avoids that the suture is fixedly pressed on the same muscle layer area for a long time, and reduces the risk of necrosis.

[0032] The sheath 3 and the suture 4 are intersected in the downward projection direction, the projection intersection ensures that the cutting track of the blade 2 accurately covers the suture 4, and avoids repeated cutting or cutting failure.

[0033] The bottom of the hollow sphere 1 is provided with a round hole 7, the first pull wire 5 penetrates through the round hole 7, the first pull wire 5 independently leads out through the round hole 7 arranged at the bottom of the hollow sphere 1, the first pull wire 5 is prevented from being entangled with the second pull wire 6, and the reliable triggering action is ensured, and the smooth inner wall of the round hole 7 reduces the risk of pull wire abrasion.

[0034] The first pull wire 5 and the second pull wire 6 are arranged in different colors, doctors can quickly distinguish the functional wires (red = cutting trigger line, blue = tension monitoring line), and misoperation leading to premature cutting is avoided.

[0035] The circular hole 7 corresponds to the suture 4 and is provided with a ball groove 71 upwardly, the suture 4 slides along the ball groove 71, and the relative scale change between the second pull wire 6 and the sheath tube 9 is linearly related to the sliding distance of the suture 4 along the ball groove 71, thereby providing a quantifiable suture removal opportunity judgment standard (such as loosening ≥2 cm and maintaining 48 hours for suture removal).

[0036] The suture removal steps are as follows: The suture 4 is inserted from the front side of the uterus, then the ball suture removal structure is placed into the uterine cavity, then the first pull wire 5 and the second pull wire 6 are respectively led out of the vaginal orifice through the sheath tube 9, the suture 4 is pulled out from the back side of the uterus, and is tied around the upper part of the uterus. With the passage of time, the suture 4 will loosen, at which time the suture 4 slides upward along the ball groove 71, at which time the angle between the second pull wire 6 and the sheath tube 3 is formed, and the second pull wire 6 is taut at the bottom of the sheath tube 3. One hand pushes the sheath tube 9 upward, and the other hand pulls the second pull wire 6 downward, and the relative scale change between the second pull wire 6 and the sheath tube 9 is used to judge whether the suture 4 is loosened. When the suture is removed, the first pull wire 5 is pulled outside the vaginal orifice, the sheath tube 3 is separated from the blade 2 along the pin shaft 8 under the action of the connecting line pulling, at which time the blade edge at the end of the blade 2 contacts the suture 4, the sheath tube 3 remains in the hollow ball 1, the sheath tube 9 is pulled outside the vaginal orifice to drive the ball to move downward, and the blade 2 is driven to cut the suture 4 downward, the suture 4 is cut, and the sheath tube 9 is pulled downward to pull out the ball.

[0037] Although the specific embodiments of the present application are described above with reference to the accompanying drawings, the present application is not limited to the above-described embodiments, and various modifications or changes can be made by those skilled in the art without creative labor on the basis of the technical solutions of the present application.
