Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and more specifically, to a support frame for cervical cerclage surgery. Background Technology
[0002] Cervical insufficiency, also known as cervical incompetence or cervical insufficiency, refers to the pathological dilation and relaxation of the cervix in the absence of uterine contractions, leading to premature expulsion of the fetus. It primarily manifests as recurrent miscarriages or premature births in the mid-to-late stages of pregnancy. Current treatments for cervical insufficiency generally involve cervical cerclage, a procedure that typically involves suturing the cervix to close it and maintain pregnancy until full term.
[0003] However, during cervical cerclage, due to the relaxation of the pregnant woman's cervix, the amniotic sac surrounding the fetus often slides through the cervix into the vagina, thus pressing against the cervical opening and keeping it excessively open. Doctors usually perform suturing operations on the cervical opening with needles and sutures that pass through the vagina. Since the vagina is relatively narrow, it is difficult for doctors to perform suturing operations on the cervix. Furthermore, with the amniotic sac pressing against the cervical opening and keeping it excessively open, it is also difficult for doctors to tie the cervix.
[0004] Therefore, existing technologies need to be improved and developed. Utility Model Content
[0005] The purpose of this application is to provide a support frame for cervical cerclage surgery, which aims to solve the problem that during cervical cerclage surgery, the amniotic sac slides through the cervix into the vagina, thereby pressing against the cervical opening and keeping the cervix excessively open, making it difficult for the physician to perform suture operations on the cervix and to tie the cervix.
[0006] This application provides a support frame for cervical cerclage surgery, used to support the amniotic sac during cervical cerclage surgery, comprising:
[0007] The transport pipe has a cap at one end for fastening and closing one end of the transport pipe;
[0008] The filling bladder is made of a flexible material, and its interior is connected to the other end of the transport tube.
[0009] The support frame provided in this application for cervical cerclage surgery can push the amniotic sac towards the uterus, so that the amniotic sac no longer presses against the cervical opening, thereby preventing the cervix from remaining excessively open, making it easier for the doctor to perform suture operations on the cervix, and making it easier for the doctor to tie the cervix up. In addition, the support frame of this application is easy to retract.
[0010] Optionally, when the bladder is in a full state, the bladder wall contracts toward the transport tube.
[0011] Optionally, when the bladder is in a full state, the bladder wall contracts toward the transport tube.
[0012] Optionally, when the filling bladder is in a full state, its side away from the transport tube smoothly transitions to its outer periphery.
[0013] In this embodiment, the present application enables the pit to conform to the local surface of the amniotic sac it contacts, thereby further increasing the contact area between the filling sac and the amniotic sac and further reducing the pressure on the amniotic sac.
[0014] Optionally, when the filling bladder is in a full state, it has a depression in the middle of the side away from the transport tube.
[0015] Alternatively, the sidewalls of the recess contract inward in the direction from away from the transport pipe to closer to the transport pipe.
[0016] Optionally, the support frame also includes:
[0017] The cervical restraint ring is a hollow structure that is placed around the outer periphery of the transport tube and is made of a flexible material.
[0018] The restraint rope passes through the cervical restraint ring, with its middle part looping inside the cervical restraint ring and its two ends positioned outside the cervical restraint ring.
[0019] In this embodiment, the present application enables physicians to more conveniently perform suturing operations on the cervix and to more conveniently tie up the cervix, and the cervical restraint ring of the present application is easy to retract.
[0020] Optionally, the outer ring of the cervical restraint ring has rounded corners.
[0021] Optionally, the inner diameter of the cervical restraint ring is 5 cm.
[0022] Optionally, the middle of the side of the pipe cap used to fasten and close one end of the transport pipe has a protruding plug for sealing one end of the transport pipe.
[0023] Optionally, when the plug is tightened at one end of the transport pipe, the diameter of the side of the plug near the pipe cap is larger than the inner diameter of the transport pipe, and the diameter of the side of the plug away from the pipe cap is smaller than the inner diameter of the transport pipe.
[0024] As can be seen from the above, the support frame for cervical cerclage surgery of this application can push the amniotic sac towards the uterus, so that the amniotic sac no longer presses against the cervical opening, thereby preventing the cervix from being excessively open, making it easier for the doctor to perform suture operations on the cervix, and making it easier for the doctor to tie the cervix up. In addition, the support frame of this application is easy to retract.

[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figure 1 and Figure 2 As shown, this application provides a support frame for cervical cerclage surgery, used to support the amniotic sac during cervical cerclage surgery, comprising:
[0033] The transport pipe 1 has a pipe cap 11 at one end for fastening and closing one end of the transport pipe 1;
[0034] The filling bladder 2 is made of a flexible material and its interior is connected to the other end of the transport tube 1.
[0035] Specifically, during the cervical cerclage procedure, a deflated amniotic sac 2 is inserted through the vaginal opening via a transport tube 1, allowing it to pass through the vagina and cervix and contact the amniotic sac. Air or water is then introduced into one end of the transport tube 1 to inflate the amniotic sac 2. The tube cap 11 is then closed at one end of the transport tube 1, and the transport tube 1 is gently pushed to push the amniotic sac 2 into the cervix, pushing the amniotic sac towards the uterus. This prevents the amniotic sac from pressing against the cervix, thus preventing the cervix from remaining excessively open. This makes it easier for the doctor to perform sutures on the cervix and to tie it off.
[0036] More specifically, after the doctor ties up the cervix, the tube cap 11 is opened, and water or air is pumped out at one end of the tube using a negative pressure device or other device for pumping water or air, so that the filling sac 2 returns to a deflated state. Then the transport tube 1 is pulled out to remove the entire support frame. Therefore, the support frame of this application is easy to retract.
[0037] The support frame for cervical cerclage surgery of this application can push the amniotic sac towards the uterus, so that the amniotic sac no longer presses against the cervical opening, thereby preventing the cervix from remaining excessively open, making it easier for the doctor to perform suture operations on the cervix, and making it easier for the doctor to tie the cervix. In addition, the support frame of this application is easy to retract.
[0038] Preferably, the transport pipe 1 is made of a rigid material.
[0039] Preferably, the transport pipe 1 is a transparent pipe.
[0040] In some preferred embodiments, when the filling bladder 2 is in a full state, the bladder wall contracts toward the transport tube 1.
[0041] Specifically, since the filling sac 2 contacts the amniotic sac based on the side of it away from the transport tube 1, in this embodiment, when the filling sac 2 is in the inflated state, the sac wall contracts toward the transport tube 1, which can increase the contact area between the filling sac 2 and the amniotic sac and reduce the pressure on the amniotic sac.
[0042] In some preferred embodiments, when the filling bladder 2 is in a full state, its side away from the transport tube 1 smoothly transitions to its outer periphery.
[0043] In this embodiment, the support frame for cervical cerclage surgery of this application can prevent the cervix and cervix from coming into contact with sharp edges and corners, thus avoiding damage.
[0044] In some preferred embodiments, when the filling bladder 2 is in a full state, it has a recess 21 in the middle of the side away from the transport tube 1.
[0045] In this embodiment, the support frame for cervical cerclage surgery of this application is provided with a recess 21, which allows the filling sac 2 to contact the amniotic sac based on the recess 21, thereby further increasing the contact area between the filling sac 2 and the amniotic sac and further reducing the pressure on the amniotic sac.
[0046] In some preferred embodiments, the sidewalls of the recess 21 contract inward in a direction away from and towards the transport pipe 1.
[0047] Specifically, since the amniotic sac is generally curved when it presses against the cervix, the local surface of the amniotic sac surrounded by the cervix is curved. Therefore, in this embodiment, the present application can make the pit 21 fit against the local surface of the amniotic sac it is in contact with, thereby further increasing the contact area between the filling sac 2 and the amniotic sac and further reducing the pressure on the amniotic sac.
[0048] In some preferred embodiments, the support frame further includes:
[0049] The cervical restraint ring 3 is a hollow structure, which is placed around the outer periphery of the transport tube 1 and is made of flexible material.
[0050] The restraint rope 4 passes through the cervical restraint ring 3, with its middle part looping inside the cervical restraint ring 3 and its two ends set outside the cervical restraint ring 3.
[0051] Specifically, before using the support frame of this application, the two ends of the restraint rope 4 are tightened so that the cervical restraint ring 3 is in a wrinkled state similar to the waistband of pants, and the restraint rope 4 is knotted to fix the cervical restraint ring 3 to the outer periphery of the transport tube 1. This allows the cervical restraint ring 3 to enter the vagina along with the transport tube 1. Afterward, the knot of the restraint rope 4 is untied to allow the cervical restraint ring 3 to return to its normal state. The cervical restraint ring 3 is then moved to the outer periphery of the cervix, and the two ends of the restraint rope 4 are tightened again and knotted. This allows the cervix to be temporarily tied up based on the tightened cervical restraint ring 3, thus temporarily closing the cervix. This makes it easier for the doctor to perform suture operations on the cervix and makes it easier for the doctor to tie up the cervix.
[0052] More specifically, after the doctor ties up the cervix, the knot of the restraint rope 4 is untied to allow the cervical restraint ring 3 to return to its normal position. The cervical restraint ring 3 is then removed so that it is no longer located on the periphery of the cervix. The two ends of the restraint rope 4 are tightened again and knotted to fix the cervical restraint ring 3 on the periphery of the transport tube 1. The cervical restraint ring 3 can then be removed by pulling out the transport tube 1. Therefore, the cervical restraint ring 3 of this application is easy to retrieve.
[0053] In this embodiment, the present application enables physicians to perform suturing operations on the cervix more conveniently, and enables physicians to tie up the cervix more conveniently. Furthermore, the cervical restraint ring 3 of the present application is easy to retract.
[0054] In some preferred embodiments, the outer corners of the cervical restraint ring 3 are rounded.
[0055] In this embodiment, the support frame for cervical cerclage surgery of this application can prevent the cervix from coming into contact with sharp edges and corners, thus avoiding damage.
[0056] In some preferred embodiments, the inner diameter of the cervical restraint ring 3 is 5 cm.
[0057] In this embodiment, the support frame for cervical cerclage surgery of this application sets the inner diameter of the cervical restraint ring 3 to 5cm, which enables the cervical restraint ring 3 to be large enough to cover the cervical opening and prevents the cervical restraint ring 3 from being too large to be difficult to operate.
[0058] In some preferred embodiments, the middle of the side of the pipe cap 11 used to fasten and close one end of the transport pipe 1 has a protruding plug 111 for sealing one end of the transport pipe 1.
[0059] In this embodiment, the support frame for cervical cerclage surgery of this application is provided with a protruding plug 111, which enables the tube cap 11 to be conveniently fastened and closed at one end of the transport tube 1 based on the protruding plug 111.
[0060] like Figure 3 As shown, in some preferred embodiments, when the plug 111 is plugged at one end of the transport pipe 1, the diameter of the side of the plug near the pipe cap 11 is larger than the inner diameter of the transport pipe 1, and the diameter of the side of the plug away from the pipe cap 11 is smaller than the inner diameter of the transport pipe 1.
[0061] In this embodiment, when it is necessary to tighten the protruding plug 111 at one end of the transport tube 1, the side of the protruding plug 111 near the tube cap 11 is more easily inserted into one end of the transport tube 1, and the protruding plug 111 can tighten one end of the transport tube 1.
[0062] Preferably, the protruding stopper 111 is a rubber stopper.
[0063] Preferably, the length of transport pipe 1 is 20cm.
[0064] As can be seen from the above, this application provides a support frame for cervical cerclage surgery, which can push the amniotic sac towards the uterus so that the amniotic sac no longer presses against the cervical opening, thereby preventing the cervix from remaining excessively open, making it easier for the doctor to perform suture operations on the cervix, and making it easier for the doctor to tie up the cervix. In addition, the support frame of this application is easy to retract.
