Description
Technical Field
The invention belongs to the technical field of medical appliances, and particularly relates to a novel multipurpose ligation device and a use method thereof.
Background
The ligature device technology is an emerging treatment means in the medical industry, and is widely used in the medical and health industries at present. Mainly comprises a rubber ring type loop ligature device and a metal loop ligature device. The rubber ring type ligation device generally comprises a rubber ring and an elastic thread, wherein the elastic thread is formed by combining 98% of cotton and 2% of rubber band, and the rubber ring type ligation device is mainly used for internal hemorrhoid ligation in anorectal department; metal ligators are commonly used in gastrointestinal submucosal treatments. At present, no wire type loop ligature device exists in the industry, and the invention creates a new loop ligature device type.
The rubber ring type ligature device tightens the hemorrhoid base part by the elasticity of the rubber ring, and the defect of the type of the invention is that the problems of ageing of the rubber ring (such as oxidation of chemical bonds such as disulfide bonds) and the inner diameter of the fixed specification of the rubber ring (the application range is limited) are necessarily faced. Firstly, the rubber ring is aged to cause the rubber ring to fall off in advance, the risk of massive hemorrhage is caused, and secondly, the rubber ring is easy to collapse due to the fact that the cover is pricked with oversized tissues based on the limitation of the inner diameter of the fixed specification of the rubber ring; the small tissue is covered and pricked, and the rubber ring is easy to slip. Therefore, only the suprahemorrhoidal mucosa ligation can be performed, but the hemorrhoid body cannot be ligated, otherwise, the bleeding is likely to be large. The elastic wire loop ligature device solves part of the problems of the rubber ring loop ligature device, and the general principle of the operation is that the tissue is firstly loop ligature and then the knot is tightened, so the elastic wire loop ligature device has more suitable tightness compared with the rubber ring loop ligature device. However, it is essentially only tightened by means of a single slipknot by means of an elastic that is not continuous. The temporary tight slipknots formed by the elastic components still have important potential safety hazards which are unavoidable in the problems of rubber ring aging and slipknots loosening. Because hidden understanding of hidden danger is not thorough, the elastic thread has appeared clinically, and the application range of the elastic thread is expanded to the hemorrhoids body and other parts. These all present a number of potential risks. Thus, there is an urgent need to reform the current technology.
The metal ligature device is generally used for the extraction and examination of polyp under gastrointestinal mucosa, and has the main functions of ligature and electrotome (forming a capacitance field after being electrified) excision. The disadvantage is that the metal ligature device is not available when only ligation is needed, and only needs to be cut off simultaneously. And the electric knife cutting can form larger electrochemical stimulation on surrounding tissues, so that the side injury is larger, the weak tissue is easy to punch, and fat embolism is easy to cause until death near fat tissue.
The traditional manual ligation is performed by manually knotting the medical surgical thread, and the medical surgical thread has no aging problem, but because the deep part of some tissues is not easy to ligate, the artificial ligation can not be performed, so the rubber ring type loop ligature device and the metal loop ligature device are invented to solve the deep ligation, but the existing rubber ring type loop ligature device and the metal loop ligature device look like a simplified ligation treatment mode, and a new and larger potential safety hazard is formed.

The beneficial effects of the invention are as follows:
1. the invention is thoroughly different from rubber rings (comprising elastic wires) in the ligation material, and the silk threads adopted for original manual ligation are used as materials, so that the hidden trouble of excessive bleeding of the stump caused by ageing and falling off of the rubber rings in advance is avoided, and the medical safety is promoted; the application range of the invention is enlarged for the same reasons based on materials: the invention can be used in chest and abdomen operations or other in vivo operations, foreign matter residues such as rubber rings, rubber material objects, titanium clips (a clip hemostatic clip) and the like are avoided after the operations, so that the formation of foreign matter granuloma and aseptic necrosis is avoided, and as long as the medical surgical silk thread material is further defined as an absorbable thread when the invention is used, the minimally invasive surgical indications are greatly enlarged, the difficult problem of difficult ligation of hands and difficult hemostasis of minimally invasive parts is really solved, and the minimally invasive technique is greatly pushed forward.
2. The tightening mode of the rubber ring of the loop ligature device is different from that of the rubber ring of the loop ligature device. The structure of the loop can be sleeved, no matter the size, the tightening node can be tightened to form a dead knot, and the loop can be tightly and effectively sleeved.
3. The medical surgical thread dead knot tying method of the invention realizes a durable and reliable tightening effect, and compared with elastic threads, the second beneficial effect of the invention is realized temporarily only through an elastic slipknot. Because the elastic thread made of part of the elastic material is only temporary through tightening the slipknot, the tightening effect cannot be lasting and reliable along with the aging of the material.
4. Because the ligature of the medical surgical silk thread is very firm, the ligature device can ligature large and small hemorrhoid bodies directly, is not limited to the ligature of upper hemorrhoid mucosa any more, greatly reduces the requirements on individual experience of doctors, the current state of individual operations of the doctors, manual knotting capacity and the like, and reduces the operation risk.
5. Unlike metal type ligation device, the invention does not need to cut the stump by electrifying stimulation, so the invention does not have electrochemical stimulation of the metal type ligation device, does not have side damage, has little influence on surrounding tissues, and has no risk of fat embolism and death.
