Description
Technical field
This utility model belongs to a kind of medical stapling apparatus, is specifically related to a kind of for gastral Sutureless stapling apparatus.
Background technology
Medical stapling apparatus, coincide for the Sutureless between human body digester tube, for example coincideing between small intestinal two broken ends of fractured bone after operation on intestine.
Coincideing and rebuilding of object in humanbody cavity organ or blood vessel is the important operation in surgical operation, be that application suture manual suture completes in the past, can reach gratifying effect, but when operating cost, match result relies on patient's suturing skill and experience, and the complication that suture is relevant is also inevitable.Surgeon is still exploring not by the degradable of suture or nondegradable stapling apparatus or method always and is reducing operating difficulty, simplifies operating procedure, reduces post-operative complication for hundreds of years, and is making great progress in recent decades.The people such as Japanese Obora in 1978 take the lead in applying mutual magnetic attraction between two magnet rings and have completed coincideing between human pipeline's broken ends of fractured bone, and the identical concept of magnetic proposed, its principle is to squeeze human pipeline's broken ends of fractured bone tissue, cause organizing between magnet ring downright bad gradually, scar healing between the broken ends of fractured bone and complete identical; Constantly have afterwards people that magnetic is coincide and is applied to coincideing of digester tube, this center also research design has gone out a series of blood vessels, gallbladder intestinal, intestinal intestinal magnetic stapling apparatus.But magnetic stapling apparatus ubiquity foreign body is in the past residual, magnet is difficult for more greatly the drawback of taking out.The people's such as U.S. Handy in 1984 utility model patent has been introduced between a kind of object in humanbody cavity organ or human pipeline and has been coincide with device, biodegradable anastomosis ring (biofragmentable anastomotic ring, BAR), the similar magnetic of its principle coincide, and utilizes mechanical force to make broken ends of fractured bone tissue squeezing necrosis, scar healing; This device has adopted degradable poly condensation material, can on the basis that completes alimentary tract anastomosis, make stapling apparatus degradable and discharge in human body, foreign is residual, and has proved its superiority in intestinal coincide, complete at present commercialization, be widely used in clinical intestinal intestinal and coincide.But this degradable stapling apparatus is still comparatively complicated, inevitable because operating complication former thereby that occur.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is a kind of for gastral Sutureless stapling apparatus that the purpose of this utility model is to provide, and the Sutureless that relies on the suction between magnet can complete between the digestive tract broken ends of fractured bone coincide.
In order to achieve the above object, the technical scheme that this utility model is taked is:
A kind of for gastral Sutureless stapling apparatus, comprise the first annulus 1 and second annulus 2 of a pair of mutual coupling, on the plane of a loop of the first annulus 1, be inlaid with plural hemispherical the first magnet 3, accordingly, on the plane of a loop of the second annulus 2, be inlaid with plural hemispherical the second Magnet 4, the first magnet 3, the second magnet 4 bottom surface magnetic poles are contrary, the first magnet 3 and the second magnet 4 adhesive glomeration between two when the first annulus 1 and the second annulus 2 adhesive;
The internal diameter of the first described annulus 1 is greater than the internal diameter of the second annulus 2;
Described the first annulus 1 and the second annulus 2 adopt human body degradation material to make;
Described the first annulus 1, the second annulus 2, the first magnet 3 and the second magnet 4 have good biocompatibility.
Described the first magnet 3, the second magnet 4 diameters are less than digestive tract internal diameter.
The first described magnet 3 and the second magnet 4 magnetic force are 3000-4000 Gauss.
This utility model is simple and efficient to handle, reliable for effect, and the Sutureless that can be applicable to most digester tubes coincide, and reduces because of manual operation factor and the residual identical related complication causing of foreign body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3-1 is the schematic diagram of the first annulus 1, and Fig. 3-2 are the schematic diagram of the second annulus 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, taking little end to end intestinal anastomosis as example, a kind of for gastral Sutureless stapling apparatus, comprise the first annulus 1 and second annulus 2 of a pair of mutual coupling, on the plane of a loop of the first annulus 1, be inlaid with 3 hemisphericals the first magnet 3, accordingly, on the plane of a loop of the second annulus 2, be inlaid with 3 hemisphericals the second Magnet 4, the first annulus 1 and the second annulus 2 are positioned over respectively digestive tract two broken ends of fractured bone 6, in the end flap 5 of the broken ends of fractured bone 6, turn over, the first magnet 3, the second magnet 4 bottom surface magnetic poles are contrary, thereby the first magnet 3 and the second magnet 4 attract each other and the first annulus 1 and the second annulus 2 are inhaled mutually clamp end flap 5 to complete identical, the first magnet 3 and the second magnet 4 adhesive glomeration between two when the first annulus 1 and the second annulus 2 adhesive,
The internal diameter of the first described annulus 1 is greater than the internal diameter of the second annulus 2, complete coincide after in turn over and organize end recessed to the second annulus 2 one sides, can be because of the interior too much blocked up match result that affects of tissue that turns over;
Described the first annulus 1 and the second annulus 2 adopt human body degradation material to make;
Described the first annulus 1, the second annulus 2, the first magnet 3 and the second magnet 4 have good biocompatibility, and Secure Application there will not be serious toxic and side effects in human body.
Described the first magnet 3, the second magnet 4 diameters are less than digestive tract internal diameter, and between two to inhaling the spherical magnet of rear formation, are easy to move with peristalsis of the digest tract, and can be safe, complete excrete, can not cause that intestinal blocks.
The first described magnet 3 and the second magnet 4 magnetic force are 3000-4000 Gauss.
Operation principle of the present utility model is:
Complete coincide after lasting suction oppress between the first annulus 1 and the second annulus 2 end flap 5 and make it downright bad gradually, the broken ends of fractured bone 6 digestive tract hamartoplasias are carried out the seriality of alimentary reconstruction, degradation material disintegrate gradually in digestive tract simultaneously, the first magnet 3 of inhaling, the second magnet 4 are attracted and glomeration between mutually, with the degradation material fragment of disintegrate jointly along with peristalsis of the digest tract excretes.
