Description
Technical field
This utility model relates to technical field of medical instruments, specifically, relates to a kind of operative incision dilator.
Background technology
Kidney transfer operation is generally acknowledged it is the best therapy for the treatment of chronic renal failure by the whole world at present, and be the transplanting that in solid organ transplantation, technology is the most ripe, success rate is the highest, kidney survival rate reaches 96.3%.Kidney transfer operation generally needs three hours, and does not need to excise original two kidneys.This operation adopts hypogastric region curved incision, and the transplanted kidney of implantation is placed at iliac fossa, then by the blood vessel of transplanted kidney with the iliac vessels of receptor coincide, by identical for the bladder of the ureter of transplanted kidney and receptor.
Operative incision dilator is often used in renal transplantation, other urological surgeries and other surgical operations.Chinese patent literature CN201420239908.3, publication date 2014.12.17, disclose a kind of laparoscopic surgery supporting open abdominal wall device, this supporting open abdominal wall device comprises two clamp pieces, cross-coupled two clamp pieces are fixedly connected into by jointed shaft and are integrated mutually, each clamp piece is divided into handle ring, clamp handle and head end successively, and described head end is provided with groove and blunt nosed.Use result shows, top is semicircle blunt nosed, can prevent from injuring the hollow organs such as intestinal tube when inserting abdominal cavity of patients; Two groove positions are symmetrical concave surfaces, and concave part has perpendicular to clamp handle band out of shape, can limit stomach wall and slide to be strutted.
Chinese patent literature CN200720041300.X, publication date 2008.07.16, disclose a kind of expanding device for abdominal operation, described expanding device for abdominal operation is made up of adjustment device for spreading, lowering or hoisting gear and fixture, and lowering or hoisting gear comprises coupling sleeve and is inserted in the metal straight rod of this coupling sleeve; Fixture comprises two pieces of straps; Regulate device for spreading to strut bar by two parallel straight shape mobile jibs and two to form, two straight parallel shape mobile jibs are fixed on the coupling sleeve of lowering or hoisting gear, and this coupling sleeve is movably set on two straight parallel shape mobile jibs; Two strut distraction plate bar being arranged respectively and inserts otch, be provided with between two straight shape mobile jibs and strut bar position adjusting lever, this struts bar position adjusting lever and is provided with one section of external screw thread, between two straight parallel shape mobile jibs, coupling sleeve is provided with the female thread matched with external screw thread, strut on the front end of bar position adjusting lever and coupling sleeve and be rotationally connected, be provided with locking device strutting on the adjusting lever of bar position.This motion strutting bar is completely controlled, and the size of softened wound is easy to accurate adjustment as required.
At present, along with the raising of people's living standard and the day by day busy of work, diet is uncontrolled causes the partially fat number ratio of the bodily form to increase with not getting enough athletic exercise, and this type of crowd's abdominal part piles up significant quantities of fat.Be expert at abdominal operation as renal transplantation time, itself need the scope of organization that struts different owing to performing the operation and clinical conventional operative incision dilator effectively can not regulate the depth of dilator, otch surrounding tissue can not be effectively strutted in operation technique, cause surgical field of view bad, make troubles to operation technique.Therefore need badly and a kind ofly all well can retract otch when being applied to the patient of different fat or thin degree, fully expose the dilator of surgical field of view.
Chinese patent literature CN201210545407.3, publication date 2014.06.18, disclose a kind of disposable surgical dilator, be made up of two elastic dilatation circles and cylindric isolating membrane, described elastic dilatation circle is connected to cylindric isolating membrane two ends, described two elastic dilatation circles are strut circle and insert circle respectively, described in strut the cross section of circle rounded, described in insert the cross section of circle in " 8 " font.This dilator one people can complete installation, substantially increase procedure efficiency, and double elastic dilatation circle and longitudinal section are the airflow design of the inserting circle more convenient adjustment operation desired depth of the figure of eight, this utility model adopts medical-grade plastics material to make, with low cost, generalization is good.
But the shape of above-mentioned surgical dilator cylindrical shape is more difficult fixing, depth adjustment limited use produces interference to operation technique.Therefore need badly and be a kind ofly applicable to the operation of different building shape kidneys of patients, all fully can appear surgical field of view and structure incision distraction device simple, easy and simple to handle.
