Wherein, the bottom of first bowl-like cover has the first through hole, the bottom of second bowl-like cover has the second through hole, the inner sides of first and second bowl-like covers have the connection devices of them, the each of first and second bowl-like covers has a connection part, and when the first and second bowl-like covers are connected via the connection devices, their connection parts can be jointed tightly, while they are all made from the degradable material. The invention has simple structure and easy operation which has fast speed to anastomose the stomach and intestine to avoid worse effect on the human body.
Description
Technical field
The present invention relates to a kind of degradable built-in anastomat, this anastomat is mainly used in reparation, the reconstruction of the gastrointestinal broken ends of fractured bone behind the gastrointestinal resection operation.
Background technology
Directly two broken ends of fractured bone are carried out with the mode of suturing with thread management for general employing of the anastomosis operation in the gastrointestinal procedures in the hospital at present, but this suture way operation easier is bigger, and the operation consumed time is also many, and operation lacks standardization, also increases the danger that complication takes place patient simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of degradable built-in anastomat simple in structure, easy to use, and it is very fast to use this anastomat to carry out the speed of gastrointestinal anastomosis, and can not produce harmful effect to human body.
For this reason, degradable built-in anastomat provided by the invention comprises the first bowl-shape cover body and the second bowl-shape cover body, the bottom of the first bowl-shape cover body has first through hole, the bottom of the second bowl-shape cover body has second through hole, the first bowl-shape cover body and the second bowl-shape cover body inboard are respectively arranged with both connecting devices, be respectively arranged with the junction surface on the first bowl-shape cover body and the second bowl-shape cover body, when the first bowl-shape cover body with after the second bowl-shape cover body is connected by connecting device, the junction surface of the first bowl-shape cover body and the second bowl-shape cover body can fit tightly; The first bowl-shape cover body, the second bowl-shape cover body and connecting device are all made by degradation material.
The connecting device of the first bowl-shape cover body and the second bowl-shape cover body can comprise first tubular connection that is arranged on the first bowl-shape cover body and second tubular connection that is arranged on the second bowl-shape cover body in the above-mentioned degradable built-in anastomat, the first through hole conducting of first tubular connection and the first bowl-shape cover body, the second through hole conducting of second tubular connection and the second bowl-shape cover body, all have pawl on the medial surface of the lateral surface of first tubular connection and second tubular connection, first tubular connection can insert to form in second tubular connection and peg graft, and both pawls of back of pegging graft are meshing with each other.
The connecting device of the first bowl-shape cover body and the second bowl-shape cover body can also comprise first connector that is arranged on the first bowl-shape cover body and second connector that is arranged on the second bowl-shape cover body in the above-mentioned degradable built-in anastomat, first connector watt constitutes by being fixed in first around first through hole circular arc watt and the first cylindrical arc, the diameter of the first cylindrical arc watt is greater than the diameter of capable watt of circular arc in first, circular arc watt outward extending distance is greater than the first cylindrical arc watt in first, the arranged outside of circular arc watt has pawl in first, and the inboard of the first cylindrical arc watt is provided with pawl; Second connector watt constitutes by being fixed in second around second through hole circular arc watt and the second external arc row, the diameter of the second cylindrical arc watt is greater than circular arc in second watt, circular arc watt outward extending distance is greater than the second cylindrical arc watt in second, the inboard of the second cylindrical arc watt is provided with pawl, the arranged outside of circular arc watt has pawl in second, the diameter of the diameter of the first cylindrical arc watt and the second cylindrical arc watt is identical, and the diameter of the diameter of circular arc watt and the second interior circular arc watt is identical in first; After first tubular connection and the grafting of second tubular connection, the outside of circular arc watt is adjacent to and both pawls are meshing with each other in the inboard of the first cylindrical arc watt and second, the inboard of the outside of circular arc watt and the second cylindrical arc watt is adjacent to and both pawls are meshing with each other in first, the two side ends of circular arc watt offsets in the two side ends of the first cylindrical arc watt and second, and the two side ends of the two side ends of circular arc watt and the second cylindrical arc watt offsets in first.
Because degradable built-in anastomat of the present invention comprises the first bowl-shape cover body and the second bowl-shape cover body, both are respectively arranged with connecting device in the inboard, when the first bowl-shape cover body with after the second bowl-shape cover body is connected by connecting device, the junction surface of the first bowl-shape cover body and the second bowl-shape cover body can fit tightly, only need or be bundled on the anastomat monomer when using degradable built-in anastomat of the present invention to carry out gastrointestinal anastomosis gastrointestinal broken ends of fractured bone pocket, involutory again anastomat is promptly finished anastomosis procedures, this mode of operation is simple, and identical speed is very fast, degradable built-in anastomat hollow structure of the present invention in addition, not influencing gastrointestinal contents passes through, help in time recovering gastrointestinal function, also has certain degree of hardness and toughness, both can guarantee that anastomotic stoma had intensity, and guarantee safety in anastomosis procedures again, this anastomat can be degraded in digestive tract after organizing healing fully fully, a part directly excretes, and also body is had no adverse effects even another part absorbs.
