Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, a surgical ligature wire device in this embodiment includes a handle housing 1 and a plurality of wire cores, a plurality of wire cores are slidably arranged in the handle housing 1, and one end side of the handle housing 1 The wall is provided with an adjustment opening 2, and the other end of the handle housing 1 is provided with an end opening 7 for the extension of the wire core body; the wire core body includes a wire core housing 4, a switch 3 and a wire 5, and the wire core housing One end of the body 4 is provided with a switch 3, the switch 3 extends out of the adjustment opening 2, the wire 5 is arranged inside the wire core housing 4, the other end of the wire 5 extends out of the wire core housing 4, and the inner side wall of the wire core housing 4 is provided There is a cutting device for cutting the silk thread 5; when in use, push the corresponding switch 3 forward, the thread core body protrudes from the end op...

Embodiment 2

[0039] Such as figure 1 and figure 2 As shown, a surgical ligature thread device in this embodiment includes all the technical features in Embodiment 1. In addition, the end of the handle housing 1 facing away from the adjustment opening 2 is provided with a tapered portion 6, The end opening 7 is arranged on the smaller end surface of the tapered part 6, wherein the tapered part 6 is a conical shell structure.

[0040] The beneficial effects of this embodiment are: the tapered portion 6 is provided at the end of the handle housing 1 away from the adjustment opening 2, which reduces the space occupied by the instrument to a certain extent, avoids scratching surrounding tissues during operation, and has high safety.

Embodiment 3

[0042] Such as Figure 3 to Figure 5As shown, a surgical ligature wire device in this embodiment includes all the technical features in Embodiment 2. In addition, the cutting device is an annular blade 9, and the annular blade 9 is arranged on the inner side of the wire core housing 4 On the wall, the distance between the surface where the annular blade 9 is located and the end surface of the outlet edge of the wire core housing 4 is 0.5 cm. In addition, the distance between the surface where the annular blade 9 is located and the end surface of the outlet edge of the wire core housing 4 can also be other arbitrary values; Wherein, the annular blade 9 is Figure 6 One-piece ring-cut structure as shown, or as Figure 7 The shown annular cutting structure is provided with several cutting edge notches 10 .

[0043] Such as Figure 7 As shown, in some optional embodiments, the inner side of the annular blade 9 is provided with a plurality of blade notches 10, and a plurality of...

Abstract

The invention discloses a ligature device. The ligature device comprises a handle shell and a plurality of wire core bodies, the wire core bodies are arranged in the handle shell in a sliding mode, anadjusting open hole is formed in a side wall of one end of the handle shell, and an end open hole allowing the wire core bodies to extend out is formed in the other end of the handle shell; the wirecore body comprises a wire core shell, a switch and a silk thread, the switch is arranged at one end of the wire core shell and extends out of the adjusting hole, the silk thread is arranged in the wire core shell, the other end of the silk thread extends out of the wire core shell, and a cutting device used for cutting the silk thread is arranged on an inner side wall of the wire core shell. During use, the corresponding switch is pushed, the wire core body extends out of an end opening, the silk thread is drawn to a specified length for ligation, and the silk thread is pulled towards the cutting device to be cut off. The ligature device can play a major role in reducing workload of medical care, realize shortening of operation time of a patient, and reduce consumption of the patient during the operation to a certain extent.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical ligature thread device. Background technique [0002] In the prior art, the pliers are used to clamp the thread around the pliers that have clamped the blood vessel, and the end of the thread is loosened to ligate the blood vessel to stop bleeding. Using the hemostat with the thread to ligate the blood vessel requires the instrument nurse to carry the thread and then pass it on to the surgeon or assistant, increasing the Equipment nurses work, and the transmission takes a certain amount of time. The disadvantages of the existing technology are: the workload of the nurse is large, the operation efficiency is low, the operation time is long, the workload of the medical staff is large, and the patient's operation consumes a lot, which is not conducive to the patient's safety. recover. Contents of the invention [0003] Therefore, the present invention provi...
