Abstract

A vascular tissue ligator for laparoscopic surgery comprises a ligating head, a ligating bar and a ligature pulling ring. A movable blade with a wire hook on the front end is connected with the front upper end of the ligating bar with an inner ligature leading slot and an external ligature leading slot by a bolt, and the tail end of a fixed blade with an U-shaped socket on the front end is welded on the front lower end of the ligating bar. The ligature pulling ring with a finger hook on the lower part is sleeved on the ligating bar. The two sides of the ligature pulling ring, which correspond to the ligature leading slot, are provided with set screws, and the outer side of the ligature pulling ring is also provided with a ligature tying hole. The inside of the ligating bar is a ligating bar cavity, and a pulling bar is arranged in the cavity. The upper part of the approximate tail end of the ligating bar is provided with an orientating and positioning bar. A spring arranged in a spring box of the ligating bar is sleeved on the pulling bar, and the top end of the pulling bar is screw-threaded with a pressing cap. The front end of the ligature leading slot on the inner side of the ligating bar is of a side recess, and the front end of the ligature leading slot on the outer side of the ligating bar is of a small recess. All the relative parts are connected in series by silk thread or absorbable ligature. The vascular tissue ligator has the advantages that structure is simple, function is perfect, performance is stable and reliable, the threading, transfixing and ligating can be singly completed, the operation is convenient, and time-and-labor-saving, effect is good, and no affect can generate on the following-up magnetic resonance imaging of the patient to be operated.

Description

The vascular tissue's ligature carrier that is used for laparoscopic surgery

Technical field

This utility model is a kind of medical apparatus and instruments that is used at laparoscopic surgery, ligation blood vessel or tissue.It also can be used for the ligation of open surgery deep blood vessel or tissue.

Background technology

There are big blood vessel or tissue to need ligation in the time of in laparoscopic surgery, but, limited the use of routine operation and operating theater instruments because tract is narrow.In the case, during laparoscopic surgery, need to use multiple apparatuses such as down-lead device, knot pusher, mosquito forceps just can finish the ligation of blood vessel or tissue.Its shortcoming is: the patient must be through long-term training, and is skilled, and waste time and energy, effect is undesirable.The use disposable material that also has as titanium folder etc., mostly costs an arm and a leg, significantly increases surgery cost, and metal material stays in operation receiveing person's body, and this will influence its later nuclear-magnetism inspection and treatment.For many years, the ligature carrier that is used for the desirable vascular tissue of laparoscopic surgery never appears on the market, and is not seen in reported in literature as yet.

Summary of the invention

The purpose of this utility model is, making can be in narrow and small tract, and the method and the material of vascular tissue's ligation are finished the ligation operation with near conventional open surgery the time, and simple to operate rapidly, expense is low, the wield a kind of vascular tissue of patient ligature carrier.

This utility model is achieved by the following technical solution.

The vascular tissue's ligature carrier that is used for laparoscopic surgery is made up of ligation head, ligation bar, draw ring three parts, and division is as follows:

The ligation head; By movable leaf and fixedly leaf form (also can all make movable leaf), the front end of movable leaf has the line hook, the proximal end of movable leaf is connected the preceding upper end of ligation bar by screw.Fixedly the leaf end is welded in the front end below of ligation bar, and fixedly the leaf front end has U type teeth groove, and respectively there is a through wires hole two stile tops of U type teeth groove.When two leaf closed lines are colluded into U type teeth groove, a fixed gap is arranged between two leaves.

The ligation bar; It is a vast sky core barrel, and there are two symmetric lead-in wire grooves of stringer the both sides of body, and the outer leg front of the slot is dark hole, and the inner leads front of the slot is other opening.There is directed locating rod the proximal end top.Ligation bar chamber is arranged in the pipe, and intracavity is equipped with movable leaf opening and closing controlling organization, and the brace front end is connected movable leaf end in this mechanism, and the brace end is connected the pull bar front end.The pull bar end is with spring, and partial spring is contained in the spring box in the ligation bar.Be screwed with by medicated cap on the vertical screw thread of pull bar, press or unclamp by medicated cap by mechanisms such as pull bars, in order to control movable leaf and the fixedly opening and closing of leaf.

Stay thimble; Be enclosed within on the ligation bar slidably, the finger hook is arranged at the bottom, is screwed with stop screw with both sides lead-in wire groove correspondence position on the ligation bar, and there is bolt line hole in the outside.Stay thimble bolt line hole, fixedly through wires hole on the leaf and lead-in wire groove all have silk thread maybe can inhale line to pass through.

Manufacture method of the present utility model: process respectively or purchase and assemble by the planform of parts as shown in the figure and get final product.Need during use maybe can inhale the line polyphone with silk thread.Material is metal or engineering plastics, is good with rustless steel.Whole ligature carrier will meet the medical apparatus and instruments national standard.

Using method of the present utility model: 1, silk thread maybe can be inhaled an end bolt of line on bolt line hole.2, the through wires hole from homonymy U type teeth groove stile penetrates another free-end through outer leg groove and dark hole, passes from the offside through wires hole.3, silk thread is introduced in the inner leads groove by the other opening of inner leads groove, and with left hand drag wire tail.4, control the ligature carrier upper end with the right hand and move stay thimble to directed locating rod place.5, the ligature carrier front end is put into the art open country by cutting bayonet socket.6, press down by medicated cap movable leaf is opened, free good blood vessel or tissue are put into movable leaf with fixedly between the leaf, unclamp by the suitable stretching silk thread of adjustment of two handss after the medicated cap two leaf closures.7, press once more by the movable leaf of medicated cap and open, the silk thread in the through wires hole of both sides is hung on the hook of movable leaf (can repeat 6,7 operation) as not hanging up.8, move ligature carrier outward, leave the blood vessel that needs ligation or unclamp by medicated cap when organizing, movable leaf and fixing leaf be closure once more.9, ligature carrier is shifted out external, the free-end silk thread is pulled out from the inboard through wires hole of fixing leaf, left hand is held the line tail once more, and two lines are made knot back ligature carrier and sent into the art open country in the lump together with knot, tighten up the two ends silk thread, tighten.10, the right hand refers to decontrol and refers to that hook, stay thimble move down and fall.11, take out ligature carrier once more, after external two lines are done knot again, send into the art open country in the lump once more, the right hand refers to move on the tractive wire loop, and two ends are suitably tightened up binding and finished the 2nd knot.If needed, 10,11 operation can be repeated and a plurality of knots can be finished.

The utility model has the advantages that: simple in structure, multiple functional, stable and reliable for performance, a kind of apparatus just can be finished threading separately, does knot, ligation is all worked, easy to operate, as to reduce patient's ligation operating technology difficulty, time saving and energy saving, effective, and significantly reduce surgery cost, nuclear-magnetism inspection after the operation receiveing person and treatment are not had influence.
