Technical Field
The invention relates to the technical field of medical instruments, in particular to a structure and a method for fixing a heat-shrinkable sleeve.
Background
Female urinary incontinence is a common female disease, about half of which is stress incontinence, which means that when the bladder pressure is greater than the maximum urethral pressure, urine also does not spontaneously overflow from the external orifice of the urethra in the state of no bladder detrusor contraction, much when the abdominal pressure suddenly increases, for example: laughing, sneezing, coughing, and the like.
Urinary incontinence patients often require treatment by implanting a sling mesh during treatment. The treatment mode has the advantages of high cure rate, simple and convenient operation, small wound, quick postoperative recovery, few complications, low recurrence rate and the like, and is widely applied clinically. The suspension belt mesh implanting operation is a minimally invasive operation, two incisions of one centimeter are respectively cut at the left side and the right side of the lower abdomen of a patient, and the biosynthetic suspension belt mesh is placed in the middle section of the urethra.
The general method of the operation mode is that firstly, a traction line is directly penetrated in the mesh piece of the suspension belt, the sleeve is directly sleeved after knotting and fixing, and then is directly heat-shrunk on the mesh piece of the suspension belt, so that the traction line is separated from the mesh piece of the suspension belt, the manufactured heat-shrinkable sleeve is easy to slip and is not beneficial to sleeve fixing, and the risk that the heat-shrinkable sleeve slips into a human body is caused in the operation process.
Therefore, how to provide a structure and a method for fixing a heat shrinkable sleeve is a problem that needs to be solved by those skilled in the art.
Disclosure of Invention
In view of the above, the present invention provides a structure and a method for fixing a heat shrinkable sleeve. According to the invention, the annular bulge is formed by winding the sewing thread on the net piece of the suspension belt, so that the heat-shrinkable sleeve is not easy to fall off from the net piece of the suspension belt after being shrunk, and the heat-shrinkable sleeve after being shrunk is integrally conical, so that the heat-shrinkable sleeve is more firmly and reliably fixed, and the risk that the heat-shrinkable sleeve slips off and falls into a human body is reduced.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a structure of fixed heat-shrinkable tube, includes pull wire, stylolite, heat-shrinkable tube and suspends in midair and takes the net piece, the pull wire passes suspend in midair and take the net piece, the tail end arrange in suspend in midair and take the net piece outside, the stylolite winding suspend in midair and take the net piece outside to form annular bulge, the heat-shrinkable tube suit suspends in midair and takes the net piece on.
Furthermore, the height of the annular bulge is 1-2mm, the formed annular bulges are one or more uniformly distributed, and the annular bulge formed at the head end is successively lower than the annular bulge formed at the tail end.
Further, the heat-shrinkable sleeve is sleeved on the suspension belt net piece and is subjected to heat-shrinkable treatment, and the heat-shrinkable sleeve after the heat-shrinkable treatment is integrally conical.
Further, the material of the heat-shrinkable tubing is polyethylene or polytetrafluoroethylene.
Furthermore, the sewing thread is made of PET plastic or polypropylene.
A method for fixing a heat-shrinkable sleeve comprises the steps of enabling a traction wire to penetrate through a suspension belt mesh, arranging the tail end of the traction wire after the traction wire penetrates outside the suspension belt mesh, and winding the tail end of the traction wire by using a suture to form an annular bulge.
Furthermore, the height of the annular bulges formed by winding is 1-2mm, the formed annular bulges are one or more than one and are uniformly distributed, and the annular bulges formed at the head end are successively lower than the annular bulges formed at the tail end.
Further, the heat-shrinkable sleeve is sleeved on the suspension belt mesh sheet wound with the annular protrusion, a hot air gun is used for softening and heat-shrinking the heat-shrinkable sleeve, and the heat-shrinkable sleeve after heat-shrinking is integrally conical.
The invention has the advantages that the suture line is used for arranging the annular bulge, the problem that the heat-shrinkable sleeve is easy to fall off in the operation process after being shrunk is solved, the tail end of the traction line is fixed by the heat-shrinkable sleeve after being wound by the suture line, the heat-shrinkable sleeve is firmer and difficult to fall off, the heat-shrinkable sleeve is integrally conical, the pulling force is effectively reduced in the puncture process, the bleeding of a puncture part is reduced, the heat-shrinkable sleeve is more firmly and reliably fixed, and the risk that the heat-shrinkable sleeve slips and falls into a human body in the operation process is reduced.
