Description

Technical Field

[0001] The utility model specifically relates to a pelvic floor repair mesh. Background Art

[0002] Pelvic organ prolapse (POP) is an abnormal position and function of organs caused by the descent of pelvic organs due to abnormal pelvic floor muscles and fascia tissues. The main symptom is the prolapse of vulvar masses, accompanied or not by abnormal urination and defecation, which affects the quality of life of patients to varying degrees. Studies have shown that women have a lifetime risk of about 13% to undergo surgical treatment for POP. Pelvic floor reconstruction surgery is currently used clinically for this type of disease, mainly including autologous tissue repair and mesh repair. Autologous tissue repair has high requirements for surgeons, a long learning curve, and a high recurrence rate; mesh repair includes transvaginal placement of pelvic floor mesh and transabdominal placement of pelvic floor mesh. Transvaginal placement of pelvic floor mesh is often suitable for elderly patients, and its surgical anatomical reduction effect is better than that of autologous tissue, but it requires blind puncture and is prone to damage to organs;

[0003] The current standard surgical procedure for treating apical defects in clinical practice is transabdominal vaginal sacrocolpopexy, but it has a long learning curve, requires high levels of deep pelvic anatomy, and may have serious complications such as presacral vascular bleeding, intestinal and urinary system damage, etc.

[0004] With the acceleration of population aging, the number of POP patients is gradually increasing, which not only requires surgeons to improve their skills, but also puts higher demands on the development of biosynthetic mesh.

[0005] In recent years, the transvaginal mesh used in total pelvic floor reconstruction surgery often uses 4-wing molded meshes of different specifications, which have deep branches and superficial branches. After the vesico-vaginal space is separated by a combination of blunt and sharp methods to reach the bilateral ischial spines, two skin entrances are made on each side to place two groups of deep and shallow mesh branches. The first skin landmark is at the level of the external urethral orifice of the bilateral genital femoral skin folds, and the second skin landmark is on the inner side of the bilateral thighs, 1 cm outside and 2 cm below the previous landmark. By using a special puncture needle, the superficial branch of the mesh is fixed on the pelvic fascia tendinous arcus from the outside to the inside through the first skin incision; similarly, from the second skin landmark, the deep band of the mesh is placed on the pelvic fascia tendinous arcus from the outside to the inside.

[0006] This type of mesh still has the following shortcomings: 1. The mesh is cut to specific sizes and dimensions and then mass-produced, and is more expensive than the mesh that has not been cut; 2. Customizing a mesh of a specific shape requires a longer production cycle, and the supply is not as sufficient as the mesh that has not been cut; 3. The mesh of this specific shape can only be used for patients undergoing this surgical method, and the utilization rate of the mesh is reduced for patients who change the surgical method during surgery; 4. Mesh surgery is complicated and prone to falling off and displacement. Utility Model Content

[0033] Example 1

[0034] like Figure 1 The pelvic floor repair mesh shown includes a main body 1 , a first side arm 2 and a second side arm 3 .

[0035] The main body 1 is rectangular, and the first side arm 2 and the second side arm 3 are both rectangular. The first side arm 2 is connected to the main body 1; the second side arm 3 is connected to the main body 1. The first side arm 2 and the second side arm 3 are respectively located on two opposite sides of the main body 1 and are arranged in parallel.

[0036] In the utility model, the main body 1 of the mesh is 5 cm long and 2 cm wide, the total length of the first side arm 2 is 15 cm and the width is 2 cm; the total length of the second side arm 3 is 41 cm and the width is 2 cm; the main body 1 is fixed to the surface of the vaginal fascia after the surface of the bladder is repaired and strengthened; the first side arm 2 is fixed to the pelvic fascia tendon arch 2 cm above the ischial spine, and is positioned at the level of 1 cm outside and 2 cm below the external orifice of the urethra at the bilateral genital femoral skin folds; the second side arm 3 is fixed to the bilateral sacrospinous ligaments, and is positioned at 3 cm outside and 3 cm below the anus through the ischioanal fossa.

[0037] The above dimensions are only the preferred proportions and dimensions for a normal human body. Depending on the race, height, size of the uterus and vagina, degree of prolapse, and degree of force required, the width of the main body 1 of the mesh can be adjusted while maintaining the entire shape, and can be extended to 2-3 cm. The unused portion of the mesh after suturing can be sutured and then cut off.

[0038] The manufacturing method of the pelvic floor repair mesh of the present utility model specifically includes the following steps: Use a mesh with a specification of 10*15 cm. First, cut out two mesh side arms with a length of 15 cm and a width of 2 cm to prepare for suturing with the main body part 1; then cut the main body part 1: Take the remaining mesh, fold it along its long axis, measure a length of 2 cm on the shorter side, and cut out a rectangular mesh with a length of 5 cm and a width of 2 cm, leaving an "I"-shaped mesh with a length of 15 cm and a middle width of 2 cm. Suture the two previously cut mesh side arms to the left and right sides at the lower end of the "I"-shaped mesh respectively. Among them, overlap the mesh on the left side of the lower end of the "I"-shaped mesh with one of the mesh side arms by 2 cm, and use 2-0 non-absorbable valve line for continuous suture or folding suture. The other mesh side arm is connected to the "I"-shaped mesh in the same way. Based on this, the mesh of the present utility model is sutured with the main body part 1 through the left and right mesh side arms to form an integral body. At the same time, suture lines are respectively made on the four side arms of the integral mesh for later pulling each side arm to be fixed to each body surface fixed point through the pelvic fascia tendon arch and the sacrospinous ligament. The middle part of the mesh of the present utility model is integrally formed and cut from the same mesh, which ensures the toughness of the mesh, has strong anti-tearing ability, and is not easy to tear after long-term use. And the two side arms of the mesh are cut from the same mesh and sutured with non-absorbable valve line, which is beneficial to saving materials and avoiding waste.

[0039] The using method of the pelvic floor repair mesh of the present utility model: Use a tissue forceps to clamp the anterior vaginal wall 0.5 cm below the external urethral orifice as a guide, and use another tissue forceps to clamp the anterior lip of the cervix to completely expose the anterior vaginal wall mucosa. Inject diluted adrenaline saline between the anterior vaginal wall mucosa and the bladder as a water cushion, and separate the vesicovaginal space by combining blunt and sharp dissection. Separate both sides to the vaginal side wall until reaching the ischial spine level, touch the bilateral internal obturator muscles and the arcus tendineus levator ani, separate the paracervical ring, and push up the bladder. Make an incision mark about 0.5 cm long at 1 cm lateral and 2 cm inferior to the external urethral orifice of the bilateral genitofemoral skin folds respectively to mark the first puncture point for placing the first side arm 2; make an incision mark about 0.5 cm long at 3 cm lateral and 3 cm inferior to both sides of the anus respectively to mark the second puncture point for placing the second side arm 3. The puncture needle penetrates from the first puncture point and exits from the pelvic fascia tendon arch 1 cm above the ischial spine. After putting the first side arm 2 on the tip of the puncture needle, complete the placement of the second side arm 3 in the same way: The puncture needle penetrates from the second puncture point, passes through the ischiorectal fossa through the buttock, and passes through the lower 1 / 2 of the sacrospinous ligament 2 cm medial to the ischial spine to complete the placement of the second side arm 3.

[0040] Adjust the position of the mesh so that it enters the vesicovaginal space and pads under the bladder and is tension-free; use non-absorbable sutures to fix the mesh at the bladder neck, fix the main body part 1 on the surface of the repaired and strengthened vaginal fascia on the surface of the bladder. After suturing the anterior vaginal wall fascia, cut off the redundant first side arm 2 and second side arm 3 close to the skin, and suture the skin incision with absorbable thread.

[0041] Compared with the existing female pelvic organ prolapse repair mesh, which mainly performs anterior pelvic floor reconstruction and apical support without posterior pelvic reconstruction, the utility model adopts an integrated mesh, with the first side arm 2 fixed to the bilateral pelvic fascia tendon arches, the second side arm 3 fixed to the bilateral sacrospinous ligaments, and the main body 1 fixed to the surface of the vaginal fascia after the bladder surface repair and reinforcement. The first side arm 2 is used to pull the anterior vaginal wall, and the second side arm 3 pulls the sacrospinous ligament to achieve the purpose of apical support, while correcting the defects of each cavity, correcting the central defect and the lateral defect, and simplifying the corresponding surgical operation; and there is evidence that the vaginal implantation of non-absorbable mesh can reduce the anatomical recurrence rate compared with autologous tissue pelvic floor reconstruction, especially the recurrence of the anterior vaginal wall.

[0042] The pelvic floor repair mesh of the utility model adopts the above-mentioned connection method and fixing method. The fixed position of the mesh conforms to the natural anatomical suspension position, ensuring that the left and right forces of the uterus and vagina are uniform, and the natural axis is in a forward tilted position, which conforms to the physiological structure of humans. The main body 1 is sutured to the surface of the vaginal fascia after the repair and reinforcement of the bladder surface to ensure that the mesh is stably fixed on the anterior wall of the vagina and is not easy to fall off. According to the principle of flat and tension-free placement of the pelvic floor repair mesh, the mesh can be prevented from falling off and shifting in the later stage.

[0043] Example 2

[0044] like Figure 2 The pelvic floor repair mesh shown includes a main body 1 , a first side arm 2 and a second side arm 3 .

[0045] The main body 1 is rectangular, and the first side arm 2 and the second side arm 3 are both rectangular. Two first side arms 2 are provided, symmetrically arranged on two opposite sides of the main body 1. The second side arm 3 is arranged on the side adjacent to the side of the main body 1 connected to the first side arm 2, and the second side arm 3 is perpendicular to the first side arm 2.

[0046] In the utility model, the main body 1 is 5 cm long and 3 cm wide; the first side arm 2 is 41 cm long and 2 cm wide; the second side arm 3 is 5 cm long and 3 cm wide; the two mesh side arms are 18 cm long and 2 cm wide respectively. The mesh side arms pass through the outside of the root of the round ligament, sneak along the subcutaneous peritoneum layer, and are fixed 4 cm above the anterior superior iliac spine on both sides and 3 cm outside the abdomen. The main body 1 is fixed on the cervical fascia, and the second side arm 3 of the mesh is fixed on the pubocervical fascia of the anterior wall of the vagina.

[0047] The above dimensions are only the preferred proportions and dimensions for a normal human body. Depending on race, height, size of the uterus and vagina, degree of prolapse, and degree of force required, the length of the second side arm 3 of the mesh can be adjusted while maintaining the entire shape, and can be extended to 4-6 cm. The unused portion of the mesh after suturing can be sutured and cut off.

[0048] The utility model pelvic floor repair mesh manufacturing method specifically includes the following steps: using a mesh with a size of 10*15cm, first cutting out two mesh side arms with a length of 15cm and a width of 2cm, in preparation for suturing with the main body 1; then cutting the main body 1 and the second side arm 3 of the mesh: cutting a mesh with a length of 15cm and a width of 6cm, folding the mesh in half, measuring a rectangular mesh with a length of 5cm and a width of 4cm, cutting off the rectangular mesh, leaving a T-shaped mesh with a length of 15cm and a width of 2cm, overlapping the left side of the T-shaped mesh with the mesh side arm by 2cm, using 2-0 non-absorbable valve thread for continuous suturing or folding suturing, and the other mesh side arm is also connected to the T-shaped mesh in the same way. Based on this, the utility model mesh is integrated with the main body 1 through the suturing of the left and right mesh side arms. Sewing the left and right mesh side arms separately is convenient for the later pulling side arms to pass through the peritoneum and be fixed to the abdominal wall. The main body 1 and the second side arm 3 of the utility model mesh are integrally formed and cut from the same mesh, which ensures the toughness of the mesh and strong tear resistance, and is not easy to tear after long-term use. In addition, the two side arms of the mesh are cut from the same mesh and sutured with non-absorbable valve thread, which is conducive to saving materials.

[0049] The method of using the utility model pelvic floor repair mesh is as follows: conventional uterine lifting, cutting the bladder fold peritoneum under laparoscopy, pushing the bladder down to the vaginal wall about 2 cm from the external cervical opening, placing the utility model mesh in the vaginal bladder gap, and using 2-0 non-absorbable valve thread to continuously suture the cervix and the main body 1 and the second side arm 3 of the utility model mesh 1.5 cm outside the uterine ascending branch blood vessels, suturing the main body 1 to the cervical fascia of the lower segment of the uterus, and suturing the second side arm 3 of the mesh to the pubocervical fascia of the anterior vaginal wall. Select 4 cm above the left anterior superior iliac spine and 3 cm outside the abdomen as the puncture point, puncture the peritoneal layer with the laparoscopic vascular clamp, and sneak along the peritoneal layer subcutaneously to the outside of the root of the round ligament, and pull the left arm of the mesh to the abdominal wall; the right arm is handled in the same way. Pull up the arms on both sides, and you can see that the vagina and cervix are stretched toward the head. After fixing the uterus and vagina in the appropriate position of the pelvic cavity, suture the bladder peritoneum.

[0050] Compared with the existing auxiliary device for repairing female pelvic organ prolapse mesh, the utility model removes the deep branch cut by the existing mesh during the operation, and adopts an integrated mesh. The two side arms of the mesh are respectively fixed 4cm above the anterior superior iliac spine on both sides and 3cm behind the ventral lateral side. The main body 1 is fixed to the cervical fascia, and the second side arm 3 of the mesh is fixed to the pubocervical fascia of the anterior wall of the vagina. The two side arms are used to pull the uterus and vagina and fix them in a suitable position in the pelvic cavity, so as to relieve the patient's symptoms and improve the patient's prolapse. The installation is more firm, with high stability and not easy to fall off; it avoids damage to the blood vessels, blood vessels and ureters in the sacral promontory area; it is more suitable for young and obese patients.

[0051] The utility model patent adopts the above-mentioned connection method and fixing method. The left and right side arms 1 are respectively fixed 4 cm above the anterior superior iliac spines on both sides and 3 cm behind the ventral lateral side, which conforms to the natural anatomical suspension position, ensuring that the left and right forces of the uterus and vagina are evenly distributed, and the natural axis is in a forward tilted position, which conforms to the physiological structure of humans. The main body 1 and the second side arm 3 are respectively sutured to the pubocervical fascia of the cervical fascia and the anterior wall of the vagina, ensuring that the mesh is stably fixed on the cervix and vagina and is not easy to fall off. According to the principle of flat and tension-free placement of the pelvic floor repair mesh, the left and right side arms are respectively fixed after passing through the peritoneum to the abdominal wall to avoid the mesh from falling off and shifting in the later stage.

[0052] Example 3

[0053] like Figure 3 The pelvic floor repair mesh shown includes a main body 1 , a first side arm 2 , and a second side arm 3 .

[0054] The main body 1 is rectangular, and the first side arm 2 and the second side arm 3 are both rectangular. Two first side arms 2 are provided, symmetrically arranged on two opposite sides of the main body 1. The second side arm 3 is arranged on the side adjacent to the side of the main body 1 connected to the first side arm 2, and the second side arm 3 is perpendicular to the first side arm 2. A notch 4 is provided in the middle of the second side arm 3.

[0055] In the utility model, the main body 1 is 6 cm long and 6 cm wide; the first side arm 2 on the mesh is 13 cm long and 2 cm wide; the second side arm 3 is 9 cm long and 6 cm wide; the notch 4 is 1 cm wide and 7.5 cm deep; the distance from both sides of the notch 4 to the long side of the second side arm 3 is 2.5 cm. The main body 1 is fixed to the surface of the recto-vaginal fascia after the posterior wall of the vagina is strengthened; the first side arm 2 is fixed to the sacrospinous ligaments on both sides, and is positioned 3 cm outside and 3 cm below the anus through the ischiorectal fossa; the second side arm 3 of the mesh is fixed to the outer edge of the levator ani muscle at the bilateral Ap point (3 cm from the hymen edge on the midline of the posterior wall of the vagina), and is positioned 3 cm outside and 3 cm below the anus through the ischiorectal fossa.

[0056] The above dimensions are only the preferred proportions and dimensions for a normal human body. Depending on race, height, uterine and vaginal size, degree of prolapse, and stress requirements, the mesh can be adjusted to a width of 4-6cm in the middle while maintaining the entire shape. The unused portion of the mesh after suturing will be sutured and cut off.

[0057] The utility model comprises the following steps: using a mesh with a size of 10*15cm, first cutting out two first side arms 2 with a length of 15cm and a width of 2cm, in preparation for suturing with the main body 1; then cutting out the second side arm 3 of the mesh: folding the remaining mesh along its short axis, measuring 0.5cm length on the shorter side of the folded edge with a ruler, cutting 9cm along the long axis of the folded mesh with scissors, and an arc can be seen at the top of the mesh, removing the cut mesh, and leaving two second side arms 3 of the mesh with a width of 2.5cm and a length of 9cm. The other side opposite to the second side arm 3 of the mesh is the main body 1, which is 6cm wide and 6cm long. The two first side arms 2 cut out before are sutured to the two sides of the main body 1 respectively, and the left side of the main body 1 overlaps with one of the first side arms 2 by 2cm, and suturing continuously or folding and suturing with a 2-0 non-absorbable valve line, and the other first side arm 2 is also connected to the main body 1 in the same way. Based on this, the mesh of the utility model is sutured with the main body 1 through the left and right first side arms 2. At the same time, the four side arms of the integrated mesh are sutured respectively, so that each side arm can be pulled through the sacrospinous ligament and the outer edge of the levator ani muscle of the bilateral Ap point and fixed to each surface fixing point.

[0058] The main body 1 and the second side arm 3 of the utility model mesh are integrally formed and cut from the same mesh, which ensures the toughness of the mesh and has strong tear resistance, and is not easy to tear after long-term use. In addition, the two side arms of the mesh are cut from the same mesh and sutured with non-absorbable valve thread, which is conducive to saving materials and avoiding waste.

[0059] The utility model uses a method for using a pelvic floor repair mesh, which adopts the utility model patent. The patient takes the lithotomy position, and two tissue forceps are used to clamp the lower edges of the labia minora on both sides. Physiological saline is injected between the mucosa of the posterior vaginal wall and the rectum as a water cushion. A longitudinal incision is made along the midline of the posterior vaginal wall, starting from the perineum and reaching the upper 1 / 3 of the posterior vaginal wall. The posterior vaginal wall mucosa and the rectal space are separated. The rectal hernia sac is ligated at a high position. The puncture needle makes an incision of about 0.5 cm in length 3 cm outside and 3 cm below the anus on both sides to mark the puncture point for placing the mesh. The main body 1 is placed on the surface of the recto-vaginal fascia after the posterior vaginal wall is strengthened using a 2-0 non-absorbable valve line. The puncture needle passes through the ischiorectal fossa from the outside to the inside through the buttocks from the puncture point, and passes through the lower 1 / 2 of the sacrospinous ligament 2 cm from the inner side of the ischial spine to complete the placement of the first side arm 2. At the same time, the puncture needle passes through the ischiorectal fossa from the outside to the inside through the buttocks from the puncture point, and the second side arm 3 of the mesh is fixed to the outer edge of the levator ani muscle at the bilateral Ap point (3 cm away from the hymen on the midline of the posterior vaginal wall). Adjust the position of the mesh, reinforce and suture the levator ani muscles on both sides, interrupt the rectal fascia, gradually return the rectal wall during the suturing process, and continuously suture the posterior vaginal wall mucosa. Cut off the excess first side arm 2 and second side arm 3 close to the skin, and suture the skin incision with absorbable sutures.

[0060] Compared with the existing female pelvic organ prolapse repair mesh, which mainly performs anterior pelvic floor reconstruction and apical support without posterior pelvic reconstruction, the utility model adopts an integrated mesh to return the prolapsed pelvic organs of patients with posterior vaginal wall prolapse and rectocele, by fixing the main body 1 to the surface of the vaginal rectal fascia after the posterior vaginal wall is strengthened, the first side arm 2 is fixed to the bilateral sacrospinous ligaments, and the second side arm 3 is fixed to the lateral edge of the bilateral Ap point anal levator muscles. The main body 1 is placed on the recto-vaginal fascia without tension, which provides support at level II and repairs the posterior pelvic defect. The first side arm 2 is placed at the bilateral sacrospinous ligaments to adjust the tension of the mesh covering the recto-vaginal gap, strengthen the support at level II, and repair the anal levator muscles through the second side arm 3 of the mesh to achieve the effect of strengthening the support at level III. At the same time, the mesh is placed away from the pelvic nerves and blood vessels. The utility model corrects the defects of the posterior pelvic cavity. Compared with the existing commonly used posterior vaginal wall repair surgery, the hospitalization time is shortened, and the non-absorbable mesh implanted through the vagina reduces the anatomical recurrence rate compared with the autologous tissue pelvic floor reconstruction surgery, and significantly improves the clinical manifestations of patients' defecation disorders. At the same time, compared with the existing surgical methods for treating posterior vaginal wall bulging, abdominal surgery is more traumatic to patients, and the postoperative recovery is slow and there are many complications. Transrectal surgery is easy to cause postoperative infection in patients because the surgical site is easily contaminated. However, transvaginal surgery can ensure a clear surgical field of view, less trauma, and is convenient for postoperative dressing changes and care, and patients have fewer complications.

[0061] The utility model patent adopts the above-mentioned connection method and fixing method. The main body 1 is fixed to the surface of the recto-vaginal fascia after the posterior wall of the vagina is strengthened; the first side arm 2 is fixed to the bilateral sacrospinous ligaments and is positioned 3 cm outside and 3 cm below the anus through the ischiorectal fossa; the second side arm 3 is fixed to the bilateral Ap point (3 cm from the hymen edge of the midline of the posterior wall of the vagina) and the outer edge of the levator ani muscle, and is positioned 3 cm outside and 3 cm below the anus through the ischiorectal fossa. The fixed position of the mesh is consistent with the natural anatomical suspension position, and the bulging rectum is also included, and the top of the hernia sac is sutured and closed, while ensuring that the left and right forces of the posterior wall of the vagina are uniform, and the natural axis is in a forward tilted position, which is consistent with the physiological structure of humans. The main body 1 is sutured to the surface of the recto-vaginal fascia after the posterior wall of the vagina is strengthened to ensure that the mesh is stably fixed on the posterior wall of the vagina and is not easy to fall off.
