Medical materials for the treatment of uterine prolapse

Abstract

The invention discloses a medical material for treating uterine prolapse. The medical material is characterized in that an anchor net is arranged to be a strip-like sheet, wherein clamping fins raised and extending from the two side edges are arranged at the bottom of the anchor net; cutting separation lines are arranged on an upper section of the anchor net on a body of the anchor net; when the anchor net is transversely sheared at the upper ends of the cutting separation lines, the anchor net at the positions of the cutting separation lines on a lower section can be separated into net pieces; a lead fixing hole and a bottom fixing hole are formed at an interval along the length direction of the anchor net in the lower section of the anchor net; the line end of a suspending line can sequentially penetrate through the bottom fixing hole and the lead fixing hole and form a contracted and fixed net knot around the lead fixing hole surrounding the anchor net. According to the medical material, the anchor net can be ensured to be accurately placed, the net pieces are conformally and loosely rooted to the abdominal wall to ensure and improve the anchor effect of the anchor net in the abdominal wall, and the middle part of the suspending line is accurate in positioning.

Description

technical field [0001] The invention relates to a material used for laparoscopic surgery linear abdominal wall suspension for treating uterine prolapse, more specifically a suspension wire used for suspending the prolapsed uterus to the abdominal wall, and the long-term stretching of the abdominal wall by the suspension wire Under the condition of force, the anchoring mesh strengthens the abdominal wall to prevent linear cutting and enhances the anchoring effect of the abdominal wall. Background technique [0002] Laparoscopic abdominal wall linear suspension is used to treat uterine prolapse. The prolapsed uterus is sutured and fixed with non-absorbable suspending suture. Use the suspension wire to pull the prolapsed uterus upward, so that the uterus can return and be suspended to maintain the normal anatomical position. In order to prevent the long-term stretching of the suspension wire from cutting the abdominal wall and enhance the abdominal wall’s ability to resist pul...

Problems solved by technology

However, this mesh cannot realize individualized treatment according to the difference in the thickness of the abdominal wall of the patient, especially because the abdominal wall puncture hole in which the mesh is placed is a narrow long tube, which is difficult to observe in depth, so when the suspension wire and the narrow tube are placed During the process of knotting and fixing the mesh in the puncture hole of the abdominal wall, the mesh often shrinks into a ball, and the specific depth of the mesh is difficult to locate accurately. If the mesh is placed too shallow, it will easily lead to subcutaneous induration Pain; if the mesh is placed too deep, it will easily detach from the abdominal wall, and often cause the suspension wire to be above the mesh at the suture fixed point of the abdominal wall. It acts on the mesh, but directly acts on the suspending wire on the abdominal wall suturing and fixing line, causing linear cutting of the abdominal wall and severe pain in the abdominal wall; on the other hand, the contact area between the shrunken mesh and the abdominal wall wound is reduced. The mesh slipped off under strong traction, and the cutting effect of the suspension wire eventually caused the suspension wire to lose its anchoring effect on the abdominal wall, resulting in a complete failure of the operation.

If the diameter of the mesh is increased blindly and filled in the narrow abdominal wall puncture hole without guidance, not only may the mesh shrink into a ball, but also lead to an increase of foreign bodies in the subcutaneous tissue of the abdominal wall, foreign body rejection, incision inflammation, infection, etc. complication

[0003] Because it is difficult to measure the length of the suspension line under the laparoscope, after the prolapsed uterus is sutured, the lengths of the two ends of the suspension line in the abdominal cavity are likely to be unequal, and the suspension line at one end that is too short is often difficult to suture and fix the abdominal wall

The traditional method increases the total length of the suture in order to make up for the short suspension at one end. However, due to the too long suspension in the abdominal cavity, especially the limitation of the field of view of the laparoscope, it is very easy to cause the suspension in the abdominal cavity during the suture operation. Entanglement, or even knot formation, which is like a mess, seriously affects the operation

[0004] Furthermore, the suspension thread currently used to suture the prolapsed uterus, the two ends of the thread are sutured and fixed on the abdominal wall on both sides. Since each end is a single thread, it is difficult to fix and tie the abdominal wall, and other suture needles and threads are needed. cumbersome

For this reason, two suspending wires have been used for secondary suture, that is, one suspending wire is first inserted into the abdominal cavity, and its estimated midpoint is sutured and fixed to the prolapsed uterus, and the two ends of the suspending wire are sutured in the same direction. It is fixed on the same side of the abdominal wall. Although this method provides two wire ends that can be knotted with each other to ensure the smooth knotting of the abdominal wall, but in order to achieve the fixation of the suspension wire on both sides of the abdominal wall, it is necessary to use a suspension wire to enter again. The abdominal cavity is sutured again to fix the prolapsed uterus, and then the two ends of this thread are sutured and tied with each other to fix the opposite abdominal wall, thus significantly increasing the operation time
