When the beads are connected in series to the skewer 4, adjacent faces of the beads are separated by a series tube 13, forming a rectangular slot for the snap-in suture 10. Optionally, the aperture of the serial port pipe 13 is the same as the aperture of the serial port.

As shown in fig. 2 and 3, since the front end of the wire lifter needs to extend into the affected part 12, in order to prevent the wire lifter from scratching the intestinal wall 11 or other tissues, a counter bore 8 is arranged on the front end surface of the first bead string 1, which is close to the pressing piece 5. After the compressing part 5 is tightly connected with the string rod 4, the compressing part 5 is positioned in the counter bore 8, so that the compressing part 5 can be effectively prevented from scratching the intestinal wall 11 or other tissues. Wherein, the surfaces of the first bead 1, the second bead 2 and the third bead 3 are all in arc transition.

As shown in fig. 1 and 2, the diameters of a set of first beads 1, four sets of second beads 2, and a set of third beads 3 are sequentially increased. The diameter of the first bead 1 is larger than that of the pressing piece 5, so that the pressing piece 5 can be installed in the counter bore 8 of the first bead 1. The diameter of the third bead 3 is the same as the diameter of the pipe body 6, and of course, the diameter of the third bead 3 may be smaller than the diameter of the pipe body 6. The outer wall of a plurality of beads is in an inclined shape from the tube body 6 to the pressing piece 5, so that the wire lifter can more easily extend into the affected part 12.

As shown in fig. 2, the string rod 4 has a tubular structure, and an internal thread is provided at the front end of the string rod 4. The pressing piece 5 is a screw cap, the top of the screw cap is arc-shaped, and the size of the screw cap is matched with that of the counter bore 8. Compressing tightly 5 and 4 threaded connection of boom, compress tightly a plurality of beads between compressing tightly 5 and body 6. At this point, the end of the nut is seated in the counterbore 8. Of course, pressing member 5 can also be designed as the structural style of fastener, set up the catching groove structure with the fastener adaptation in the boom 4, make and press for the buckle connection between 5 and the boom 4, also can compress tightly a plurality of beads. Or, the pressing piece 5 is connected with the string rod 4 through interference, and a plurality of beads can be pressed.

In particular, an external thread is arranged on the outer side wall of the rear end of the string rod 4, an internal thread is arranged at the front end of the tube body 6, and the string rod 4 is in threaded connection with the tube body 6. Of course, the rear end of the string rod 4 can be designed into a structural form of a fastener, a buckle groove structure matched with the fastener is arranged in the tube body 6, the string rod 4 and the tube body 6 are connected through a buckle, and the string rod 4 and the tube body 6 can be detachably connected. Or, the cross rod 4 is connected with the pipe body 6 through interference fit, and the cross rod 4 can be detachably connected with the pipe body 6.

As shown in fig. 1, a holding portion 9 is provided at the rear end of the tube body 6, and anti-slip lines are provided on the surface of the holding portion 9 to increase the friction force of the holding portion 9 and prevent the thread lifter from slipping off. Meanwhile, an operator can conveniently sterilize the wire lifter through the holding part 9. The cross rod 4, the pressing piece 5, the pipe body 6 and the beads are all made of 304 stainless steel or titanium alloy.

As shown in fig. 6, when performing laparoscopic surgery, three or four sutures 10 are firstly used to primarily suture three or four affected parts 12 with the upper hole shape of the intestinal wall 11, and then the string-threading device of the utility model is used to make the notch between the strings of beads respectively clamp each suture 10. The thread lifter is pulled upward to form the affected part 12 in a straight line shape, and finally the affected part 12 is cut or sutured by a disposable cutting stapler.

The utility model discloses only need open a stomach wall and stab the hole and can pull many sutures 10 on patient's stomach wall, reduced the stomach wall and stab the hole quantity, alleviateed patient's damage. The thread lifting device simultaneously pulls a plurality of stitches 10, the consistency of the pulling height or angle of the plurality of stitches 10 is also ensured, and the operation is simplified. A plurality of beads can be dismantled and connect on the boom 4, and on the one hand, the installation of bead and boom, dismantlement and change are more convenient, make operating personnel can dismantle the back again work of disinfecting respectively with bead, boom 4 to make the disinfection of carrying the line ware more comprehensive, more thorough, guaranteed the security of operation process. On the other hand, the string of beads and the stringing rod 4 are respectively of independent structures, and are simple in structure and convenient to produce and manufacture the string lifting device. In addition, the V-shaped notches formed between the beads can clamp the suture 10, so that the suture 10 is not easy to slip.

It can be understood that the utility model can increase or decrease the length of the string rod 4 according to the actual need of the operation, thereby increasing or decreasing the number of beads connected in series on the string rod 4. Especially when boom 4 and body 6 can dismantle the connection, can also be convenient change boom 4.
