Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a pre-anastomosis pressure magnetic induction tubular anastomat.
Background
The suturing device for anastomosis of various cavities and tracts of human body is called a tubular anastomat, can come in and go out on human body tissue, forms a plurality of rows of mutually staggered suturing nails which are arranged in the same direction, cuts off the tissue at the inner side of the suturing device by using an annular knife, and can rapidly and conveniently suture the lumen organs.
In the using operation process of the traditional tubular anastomat, whether the tissues are fully extruded or are correctly anastomosed is judged through the interval between the nail propping seat and the nail bin, so that the interval between the nail propping seat and the nail bin needs to be indicated for a doctor to judge. However, since the indicator needle to be observed by the doctor is located in the transparent indicator window on the opposite side from the firing handle, the indicator window is not directed to the doctor's line-of-sight side when the doctor manipulates the instrument due to manipulation or surgical requirements; in order to observe whether the body of the instrument rotates to the triggerable area (green area) or not, and when the body of the instrument is adjusted to the triggerable area, the doctor can influence the coordination of the doctor on the operation of the instrument (eyes, hands, instruments and tissues) when the position of the indicator needle is finely adjusted in the green area according to the thickness of the tissue.
However, the tubular anastomat sold in the market at present does not have the pre-pressure locking function, such as the bent-tube type digestive tract neck anastomat disclosed in Chinese patent No. 201220052990.X, the pointer piece disclosed in Chinese patent No. 201220732744.9, the tubular anastomat provided with the pointer piece, the tubular anastomat disclosed in Chinese patent No. 201220732605.6, the tubular anastomat disclosed in Chinese patent No. 201210582068.6, the tubular anastomat with multiple indication windows disclosed in Chinese patent No. 201820041248.6, and the like, and the scheme of how to determine the pre-anastomosis pressure is not involved. The Chinese patent 201820041248.6 discloses an indication mechanism which can rotate around an anastomat body, but has a complex structure, and cannot accurately judge the pre-anastomosis pressure, and still requires a doctor to have high skill and abundant experience on the interval between a nail abutting seat and a nail bin to judge whether tissues are fully extruded or anastomosed. Because, the mere distance determination of the difference (particularly, the difference in thickness) between the tissues of the intestinal wall or the stomach wall of the human body does not reflect the state of adhesion between the two tissues.
The tubular anastomat disclosed in Chinese patent No. 201220732605.6 describes a great deal of detail about the percussion operation of the anastomat.
The tubular anastomat has many advantages such as no tension of an anastomotic orifice, good blood supply of an anastomotic site, no inflammation, injury, edema or cancer tissue residue of an anastomotic tissue and the like. However, due to the difference of human physique, especially the difference of tissue thickness of the intestinal wall and the stomach wall of the human body, the pre-anastomosis pressure (the tissue wall to be anastomosed needs to be tightly attached together and a certain pressure is kept to realize accurate anastomosis) needs to be completely determined by the experience of doctors, and sometimes the proper pre-anastomosis pressure is determined by repeatedly adjusting the relative position of the nail supporting seat component, so that the anastomotic firing operation can be performed, the efficiency is low, the operation difficulty is high, and the problems of anastomotic stoma and anastomotic bleeding are easily caused; meanwhile, the working intensity of doctors is high and the psychological pressure is high.
