Abstract
The invention provides a spiral endoscope knotter, belonging to the field of medical instruments, particularly a knotter used in endoscopic surgery. The knotter comprises a spiral coil and a handle bar. One end of the spiral coil is connected with the handle bar and the other is provided with a threading hole. One end of a suture line is fixed in the threading hole at the end of the spiral coil and the other end thereof is connected with a suture needle. The handle bar is suitable for being captured by the grasping forcep of a laparoscope. When in use, one end of the suture line is fixed at the end of the spiral coil and the other end thereof is connected with the suture needle; the suture needle is held by a needle holder to suture or go around a target for ligation so that the suture needle goes from the proximal end of the spiral coil and passes through the center of the spiral coil, thereby allowing the spiral coil to rotate; and the suture line is removed from the spiral coil and tensed to form a knot. If the knotter is made of a flexible material such as plastic or rubber, the spiral coil is pulled downward rather than rotated. The knotter has the advantages of simple structure, easy operation, good practicability, less risk of inducing operative trauma, and low medical cost.
Description
Technical field
Helical cavity lens knotter of the present invention belongs to medical instruments field, particularly relates to the wire twister that uses in a kind of endoscope-assistant surgery.
Background technology
In the mirror surgical operation of chamber, often need knotting, what use now mostly is to adopt nipper directly with the line knotting, is an operation that difficulty is bigger, and operation is easily moved swiftly, and very unsafe, the chance of operation failure is very many, can cause operator's agitation.And chamber mirror knotting down needs bigger working place.Often the transfer open surgery causes patient's misery because tie a knot.Though titanium folder, ultrasound knife, staplers etc. can partly substitute knotting, may stay metallic foreign body, or bring the heating power damage, and expense is higher.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art and provide a kind of simple in structure, simplify the operation of knotting under the mirror of chamber effectively, it is very safe to operate, and success easily is applicable to the helical cavity lens knotter that the narrower and small endoscope-assistant surgery in space is tied a knot.
The objective of the invention is to reach by following measure, it is made up of spiral coil and handle bar, an end connection handle bar of spiral coil, and the other end of spiral coil is provided with through wires hole, suture is fixed on the end through wires hole of spiral coil, and the other end of suture connects suture needle.The handle bar is to be fit to the peritoneoscope nipper grasp.Spiral coil of the present invention and handle bar can be one, and an end of spiral coil stretches out and is fit to the extracting of peritoneoscope nipper.
Purpose of the present invention also can reach by following measure, and it is made up of spiral coil and handle bar, and an end of spiral coil is connected on the handle bar, and the handle bar is fit to the peritoneoscope nipper and grasps.Suture is fixed on the end of spiral coil, and suture is bonded on the end of spiral coil.The other end of spiral coil connects suture, and the other end of suture connects suture needle.
Spiral coil of the present invention and handle bar also can be for splits, and an end of spiral coil is fixedly connected on the handle bar, and the handle boom end is flat oval metal derby, and middle both sides cave inward, and fitted chamber mirror nipper grasps.
On the handle bar of the present invention handle can be set, handle is installed on the handle bar by bearing, on the handle bar swiveling wheel is set, and swiveling wheel is fixedly mounted on the handle bar, during use, can hand handle, by rotating swiveling wheel, the handle bar is rotated, the operation of convenient knotting.
The spiral coil number of turns of the present invention is 1.1-1.3 circle or 2.1-2.3 circle.The external diameter of spiral coil has 9MM, 4.5MM, and 2.5MM, four kinds of specifications of 1.5MM are suitable for different passages respectively.Spiral coil can adopt steel, plastics or rubber or other material.When making of flexible materials such as plastics or rubber, the external diameter of spiral coil can be bigger, because spiral coil is stretching by narrow passage in this case.
During use, suture is fixed on the end of spiral coil, the suture other end connects suture needle, needle holder catches suture needle to sew up or walk around the ligation target, and needle holder begins to pass spiral coil central authorities with suture needle from the spiral coil near-end, catches suture needle and pulls down at the spiral coil far-end again, the rotating handle bar, make the spiral coil rotation, suture is taken off from spiral coil, and tension forms knot.When making, do not need the rotating screw circle, as long as tension downwards of flexible materials such as plastics or rubber.Repeat above method and make a call to second knot, the 3rd knot.
For convenience, the part that suture is passed stitching or ligation target near suture needle is called the end of a thread, another part, and the part of promptly not passing stitching or ligation target is called the line tail.If suture needle is passed, form surgical knot in the middle of the end of a thread and line tail.If suture needle is passed, form unijunction below the end of a thread and line tail.
Spiral coil of the present invention can be a hollow pipe, and suture passes in the pipe of spiral coil, and an end of suture is fixed, and the other end of suture connects suture needle.
Handle bar of the present invention can be a hollow bushing, and an end of spiral coil is inserted in the hollow bushing of handle bar, and is fixed on the handle bar.
Fitted chamber mirror nipper grasps for convenience, and the cross section of handle bar can be ellipse.
The present invention is simple in structure, and is easy to operate, practical, can reduce operation wound effectively, reduces medical expense.
