Description

The operation involution silk device of easy ligation

The present invention relates to a kind of operation involution silk device of easy ligation, it belongs to the utensil that the involution wound in the surgical medical equipment is used, particularly use when peritoneoscope, thoracoscope and basin videoendoscopic surgery, with involution silk ligation operation position and the remaining involution silk of cut-out.

The situation of just present such operation, under the visual field of endoscope, tying up the work of involution silk can only just can be done by the doctor of high degree of skill with the endoscopy surgery utensil, therefore endoscopy surgery is restricted, carry out the lasso knot earlier in being to use external giving, the abdominal cavity is inner the operative site of blood vessel or other internal organs is entangled after the method for ligation again, but owing to the involution silk too softness can not keep certain cover loop-shaped, thereby cause being difficult to entangle operative site.For the lasso of operative site is entangled in ligation, its knot of ligation involution silk is not fixed state again but just require to strain afterwards in safety, so satisfy above-mentioned requirements sizable difficulty is arranged.In the early stage cat intestinal silks of doing that use, its shortcoming is: though it can more easily overlap the position that ligation is wanted in the residence, absorption is too fast in vivo, thereby can not guarantee the convalescent safety of patient more.In the multiple involution silk difference of hardness that recent development goes out, when operation, be not easy to entangle in vivo the position of involution with absorbability.In order to address this problem, on involution silk surface, be coated with sclerosing agent, make it to keep the cover loop-shaped of garden shape, but the very smooth knot of tying up that makes easily of involution silk that sclerosing agent is handled is loose, thereby the situation that operative site bursts apart, the operation of having to try again take place.Also there is a problem, when operation,, must takes out surgical instrument, send into shears then and block the involution silk, perhaps block, have antihygienic problem so again with used shears from the telescopic another side of sleeve needle in order to block the involution silk of ligation.

The objective of the invention is: the operation involution silk device that a kind of easy ligation is provided, its involution silk braid circle not only softness but also flexible, the shape that in the abdominal cavity, can keep the garden, entangle operative site easily, when knotting, tie up easily, bind firmly, the involution silk does not slide after operation, and the silk knot can be not loose yet.

Technical scheme of the present invention is: the operation involution silk device of easy ligation, and the inside of involution silk wherein is core, the silk screen of garden tubular on the coated outside of core; Be provided with a stay pipe, pilot hole is arranged in it, described involution silk injects in the pilot hole of stay pipe, front end at stay pipe constitutes a lasso and a knot by the involution silk, on the core on the cervical region A section between lasso and the silk knot, be not coated with sclerosing agent, and all apply sclerosing agent on the surface of the core except that the A section; The other end of involution silk is fixed on the stay pipe end, is provided with leader and an air duct hole at this end, and an interrupts grooves; Be with a guiding tube in the outside of stay pipe, make at the front end of guiding tube＜cutter blades of shape; Described core is made with individual fiber materials.

The invention has the advantages that:

1, the garden shape lasso of involution silk can be tied up operative site at an easy rate and block remaining involution silk, and the knot beaten of back is firm and do not slide tying up, can be not loose.

2, the timeliness of tying up at involution position is lacked, and patient's recovery time is short.

Consulting accompanying drawing with regard to an embodiment below elaborates to the present invention:

Fig. 1 is the assembly structure figure of involution silk of the present invention and stay pipe and guiding tube

Fig. 2 is the sketch map that the ferrule arrangement of involution silk of the present invention becomes

Fig. 3 is the partial enlarged drawing of involution silk of the present invention

Fig. 4 disconnects handle and makes lasso be in the profile of tension when use is of the present invention

Fig. 5 is mode of operation figure of the present invention

Fig. 6 is behind surgical ligation, blocks the mode of operation figure of involution silk

As illustrated in fig. 1 and 2, the operation of ligation comprises involution silk 1 and core 2 thereof with the involution silk device easily, on most of core 2, put garden tubular twine 3 after the coating sclerosing agent and form involution silk braid circle 4, with lasso 4 ligation filamentation knot 5, only on the cervical region A section between lasso 4 and the silk knot 5, be not coated with sclerosing agent.

As shown in Figure 4: involution silk 1 is injected in the pilot hole 7 of stay pipe 6, its end is fixed on the end of handle 9, the lasso 4 that is constituted then is positioned at the arrival end of stay pipe 6, when operation, utilize the interrupts grooves 8 of stay pipe 6 ends, disconnect handle 9, and outwards strain involution silk 1, also be tightened up and form silk knot at the stop lasso 4 at art position of the front end sleeve of stay pipe 6 this moment.Be with a front end makes＜guiding tube 10 of shape cutter blades 11 in the outside of stay pipe 6.When operation technique, inject under the state of guiding tube 10 at stay pipe 6, in the sleeve pipe 12 insertion abdominal paries by the trocar, reuse lasso 4 is tied up operative site, and blocks involution silk 1 with the cutter blades 11 of guiding tube 10.

Shown in Fig. 2 and 3: the core 2 of described involution silk 1 is to be made by ultimate fibre, and garden tubular twine 3 is wrapped in the outside, in order to entangle operative site easily, keeps the garden loop-shaped of lasso in the time of must operating in vivo.

As shown in Figure 5: when doing endoscopy surgery, at first use after the trocar break-through stomach wall, extract puncture needle, only stay sleeve pipe 12, the end that will be inserted with the guiding tube 10 of stay pipe 6 again pushes the sleeve pipe 12 of the trocar, and the lasso 4 that is positioned at stay pipe 6 front ends is also pushed sleeve pipe 12 together.This moment, lasso 4 was done first bundle knot as shown in Figure 6 with silk knot 5, and then tension involution silk 1 and form final silk knot 5.The core 2 of involution silk 1 is not coated with sclerosing agent on cervical region A section, and other parts all are coated with sclerosing agent and wrap garden tubular twine, so lasso 4 both can keep shape, has pliability again, can swing.

Shown in Fig. 1 and 5: when the sleeve pipe 12 of the trocar advances the abdominal cavity to stay pipe 6, the involution silk braid circle 4 that is positioned at stay pipe 6 fronts just places the position that will perform the operation, operator can undergo surgery by endoscope, used after operation involution silk braid circle 4 is tied up operative site, the stay pipe 6 that only need make a motion makes lasso 4 entangle the internal organs involution portion of operation.Subsequently, utilize the interrupts grooves 8 of sleeve pipe 12 outsides that are exposed at the trocar, disconnect handle 9, outwards strain handle 9 then, when straining along the pilot hole 7 of stay pipe 6 along with involution silk 1, lasso 4 is dwindled into gradually ties up operation.At this moment, the twine surface at silk knot 5 places of lasso 4 so it is firm again neither to slide, can not produce relaxation owing to form wrinkle during tension after tying up.

After tying up operative site with lasso 4, stay pipe 6 is pulled back, the forward involution silk 1 of silk knot 5 is exposed, stick into then guiding tube 10 ends＜shape cutter blades 11 in, press as shown in Figure 6, the direction of guide wire 10 to silk knot 5 advanced, and involution silk 1 just is cut off blade 11 at an easy rate and blocks.The described involution silk of being made by ultimate fibre 1 has in vivo through absorbed character of a period of time, and is harmless to health.The air duct hole 13 of described stay pipe 6 is provided with for sterilization after involution silk 1 being placed in the pilot hole 7.
