Abstract
The invention relates to a loop line device and particularly relates to an endoscope loop line device for minimally invasive surgery. The endoscope loop line device for minimally invasive surgery comprises a loop bar and is characterized in that the loop bar is hollow, and the interior of the loop bar is provided with a suture line; the part, which is positioned on the front end of the loop bar, of the suture line is bent and wound to form a drawable knot buckle, and the other end of the suture line and the rear end of the loop bar are glued; the part, which is 1.5-2.5cm away from the tail end, of the loop bar is cut to form an annular incision, but is not cut off; the part, which is positioned blow the annular incision, of the loop bar serves as a handle; two sides of the handle are provided with symmetrical lugs. When the loop line device is used for ligating tissues, all points are uniformly stressed, the knotted knot body expands rapidly after meeting body fluid and thus is more firm, so that accidents such as intestine leakage and gallbladder leakage are prevented from happening, and the risk of secondary surgery is avoided; after a catheter is introduced, a line body is rigid in texture and is not subjected to a turning-around phenomenon when meeting the body fluid in a cavity, so that the ligated tissues are conveniently looped under an endoscope, and the endoscope loop line device is quite worthy of popularization and application.
Description
(1) technical field
The present invention relates to a kind of snare line apparatus, particularly a kind of Minimally Invasive Surgery endoscope snare line apparatus.
(2) background technology
Snare line belongs to the medical apparatus and instruments that Minimally Invasive Surgery Microendoscopic uses, and snare line is divided into two large classes in similar industry: a class is non-absorbing snare line: be silk thread, titanium folder etc. respectively; Another kind of is Absorbable rod snare line: be respectively chemical lines and collagen protein line, but the snare line of chemical lines synthesis is that chemical industry synthetic material is made, and biocompatibility is poor.At present, China uses PGA in a large number, and PGLA, PDO class chemical synthetic material, can not be absorbed completely by human body, there is organ rejection episodes; Its material is very easily hydrolyzed, and knotting place without expansion characteristics, therefore has untwisting phenomenon, thus causes the generation of the bad accidents such as intestinal leakage, gallbladder leakage; After conduit imports, line body material is softer, in coelomic fluid, there will be phenomenon of turn-taking, and is unfavorable for ring set ligation tissue; In addition, chemical lines generally uses ethylene oxide sterilizing, and cause aseptic inflammation containing Certain residues matter, and chemical lines is very easily hydrolyzed, preservation condition is higher.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of simple, convenient Minimally Invasive Surgery endoscope snare line apparatus.
The present invention is achieved through the following technical solutions:
A kind of Minimally Invasive Surgery endoscope snare line apparatus, comprise loop bar, it is characterized in that: described loop bar hollow, inside is provided with stitching thread; The bend portions that described stitching thread is positioned at loop bar front end is wound can the knotting of pull, and the other end bonds with cover rod rear end; Described loop bar cuts into annular incision from tail end 1.5-2.5cm place, but does not cut off; Loop bar below described annular incision is handle; Described handle both sides are provided with symmetrical ear.
Described loop bar front end is tapered.
The described method that knots, comprise the following steps: one end of line body is bent this line body backward and draw close, and be wound around 3-8 circle from top to bottom, then from first lap position below being pulled upward to, being wound around after half-turn through first lap and tightening, tightening rear afterbody, to leave line body length be 10-20mm.
When the present invention uses, snare line is stretched into abdominal cavity, snare line is enclosed within affected part, hold handle, by handle annularly otch break downwardly towards interior gently, make it be separated with loop bar, then pull handle and make snare linear shrinkage, until tightened in affected part, then cutting unnecessary line body from knot 2cm right position place; Front end of the present invention is taper, agrees with, be beneficial to and penetrate with Micropore surgical equipment, practical and convenient, avoids port smooth and cannot accurately penetrate, affects the problem of procedure efficiency; The present invention is also provided with ear hands place, and when under being broken by handle, pinching ear will break down handle more easily, very convenient.
The invention has the beneficial effects as follows: the present invention is easy to use, reasonable in design, each point uniform force when the ligation of this snare line apparatus is organized, after knotting, knot body meets body fluid undergoes rapid expansion, order knot body is more firm, thus avoids the generation of the accidents such as intestinal leakage, gallbladder leakage, avoids the risk of second operation; After conduit imports, line body material is comparatively hard, runs into cavity liquid and can not to turn-take phenomenon, be convenient to ring set ligation tissue under the mirror of chamber, highly apply.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 loop bar, 2 snare lines, 3 handles, 4 annular incision, 5 knot, 6 ears.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises loop bar 1, described loop bar 1 hollow, and inside is provided with stitching thread 2; The bend portions that described stitching thread 2 is positioned at loop bar 1 front end be wound can pull knot 5, the other end and loop bar 1 rear end bond; Described loop bar 1 cuts into annular incision 4 from tail end 1.5-2.5cm place, but does not cut off; The loop bar 1 of described annular incision less than 4 is handle 3; Described handle 3 both sides are provided with symmetrical ear 6.Described loop bar 1 front end is tapered.
The described method that knots, comprise the following steps: one end of line body is bent this line body backward and draw close, and be wound around 3-8 circle from top to bottom, then from first lap position below being pulled upward to, being wound around after half-turn through first lap and tightening, tightening rear afterbody, to leave line body length be 10-20mm.
When the present invention uses, snare line 2 is stretched into abdominal cavity, snare line 2 is enclosed within affected part, hold handle 3, by handle 3 annularly otch 4 break downwardly towards interior gently, make it be separated with loop bar 1, then pull handle 3 and snare line 2 is shunk, until tightened in affected part, then cutting unnecessary line body from knot 2cm right position place; Front end of the present invention is taper, agrees with, be beneficial to and penetrate with Micropore surgical equipment, practical and convenient, avoids port smooth and cannot accurately penetrate, affects the problem of procedure efficiency; The present invention is also provided with ear 6 hands 3 place, and when under being broken by handle, pinching ear 6 will break down handle more easily, very convenient.
Describe the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
