The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to Fig. 1 ~ Fig. 5, percutaneous peritoneal stitches system, comprises the first assembly, the second assembly and nook closing member 11; The first assembly comprises circular tube shaped needle guard 10 and the feed-through collar 15 of the first hollow, nook closing member 11 or feed-through collar 15 are slidably disposed in the circular tube shaped needle guard 10 of the first hollow, and nook closing member 11 and feed-through collar 15 are arranged in the mode of mutually replacing in the circular tube shaped needle guard 10 of the first hollow (being that nook closing member 11 and feed-through collar 15 can not be arranged in the circular tube shaped needle guard 10 of the first hollow simultaneously); The second assembly comprises circular tube shaped needle guard 20 and the thread drawing hook 21 of the second hollow, the front portion of thread drawing hook 21 has for hooking the hook formation 22 of feed-through collar 15, nook closing member 11 or thread drawing hook 21 are slidably disposed in the circular tube shaped needle guard 20 of the second hollow, and nook closing member 11 and thread drawing hook 21 are arranged in the circular tube shaped needle guard 20 of the second hollow in the mode of mutually replacing.Thread drawing hook 21 be round and smooth structure foremost, avoid puncturing in use procedure abdominal viscera.
Nook closing member 11 comprises needle handle 12 and needle point 14 and the needle body 13 between needle handle 12 and needle point 14, needle handle 12, the needle body 13 and needle point 14 are integral type structure, the design of integral structure has improved the intensity of nook closing member 11, avoid running into more fat patient and in sewing process, occur the situations such as nook closing member 11 bendings, can also on needle handle 12, anti-skid design be set.
The effect of thread drawing hook 21 is to catch on feed-through collar 15 by its anterior hook formation 22, thereby the suture 30 that is connected to feed-through collar 15 can be pulled together when mobile thread drawing hook 21, therefore the intensity of thread drawing hook 21 is also very crucial, thread drawing hook 21 is that filled circles is bar-shaped, its anterior hook formation 22 is the breach from the outer wall of thread drawing hook 21 to the Axis Extension of thread drawing hook 21, and extension line and thread drawing hook 21 axis angles of this breach from the outer wall of thread drawing hook 21 to the Axis Extension of thread drawing hook 21 are 30 ~ 45 °.The anterior hook formation 22 of thread drawing hook 21 is arranged to the form of breach, avoided arranging separately in the front portion of thread drawing hook 21 on the one hand the trouble of hook formation 22, make the structure of thread drawing hook 21 simpler, on the other hand, do not increase the diameter of thread drawing hook 21, thereby can not affect the wound area size causing to patient.Inventor is through to multidigit patient's clinical trail and investigation, and investigation data have been carried out to large quantitative analysis, thinks that effect is better when the extension line of breach from the outer wall of thread drawing hook 21 to the Axis Extension of thread drawing hook 21 and thread drawing hook 21 axis angles are 30 ~ 45 °.
The circular tube shaped needle guard 10 of the first hollow is consistent with the caliber of the circular tube shaped needle guard 20 of the second hollow, nook closing member 11 is consistent with the thickness of thread drawing hook 21, the circular tube shaped needle guard 10 of the first hollow, the circular tube shaped needle guard 20 of the second hollow, nook closing member 11 and thread drawing hook 21 all adopt metallic steel to make, feed-through collar 15 adopts polypropylene material to make, polypropylene material is nontoxic, odorless, the polymer of the tasteless high crystallization of milky, quality very, there is good thermostability simultaneously, goods can be in the sterilizing that carries out disinfection of more than 100 ℃ temperature, be not subject under the condition of external force, 150 ℃ also indeformable, its chemical stability is also fine, decapacitation is by concentrated sulphuric acid, outside concentrated nitric acid corrodes, all more stable to other various chemical reagent.
Use procedure of the present invention is specific as follows:
After laparoscopic surgery, operative incision is sewed up, nook closing member 11 is located in the circular tube shaped needle guard 10 of the first hollow, the circular tube shaped needle guard 10 of nook closing member 11 and the first hollow is deep into intraperitoneal through upper epidermis, fat deposit simultaneously, then extract nook closing member 11, feed-through collar 15 is arranged in the circular tube shaped needle guard 10 of the first hollow; Again nook closing member 11 is located in the circular tube shaped needle guard 20 of the second hollow, the circular tube shaped needle guard 20 of nook closing member 11 and the second hollow is deep into intraperitoneal through upper epidermis, fat deposit simultaneously, then extract nook closing member 11, thread drawing hook 21 is arranged in the circular tube shaped needle guard 20 of the second hollow; Thread drawing hook 21 catches on feed-through collar 15 by its anterior hook formation 22, pull 21 of thread drawing hooks that suture 30 is pulled in the circular tube shaped needle guard 20 that enters the second hollow in the circular tube shaped needle guard 10 of the first hollow, then drive in the wrong direction through peritoneum, fat deposit and upper epidermis, feed-through collar 15 is exited to abdominal cavity, feed-through collar 15 exits in the circular tube shaped needle guard 20 of the second hollow, finally extract the circular tube shaped needle guard 10 of the first hollow and the circular tube shaped needle guard 20 of the second hollow, can tie a knot, repeat above-mentioned action, until sew up complete.
In the process of sewing up, suture 30 is more the interior movement of circular tube shaped needle guard 10,20 in first, second hollow, has therefore reduced the damage of suture 30 moving process to patient, the especially damage to patient's peritoneum.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
