In the orthopaedic surgical operations operation, medical anastomat has become the requisite medical assistance apparatus in the tissue apposition process.Along with the development and the research and development of products of medical science, more and more multi-functional seam nail series products is applied to clinical, and the scope of application has related to every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, gynecological, becomes one of doctor's necessary tool.The application of medical anastomat have in the operation hemorrhage less, operating time short, can reduce error hand-manipulated, avoid infection, postoperative function recovers plurality of advantages such as fast.
A kind of product commonly used is a tube type anastomat in the medical anastomat; The butt joint that is mainly used in tissue is sewed up; And technology is quite ripe; Existing anastomat provides the annulus nail of two row spaces, and annular blade excises unnecessary tissue and forms the circular anastomosis mouth after the molding of seam nail, is mainly used in the coincideing of end-to-end, end offside, side offside at the bigger position of esophagus lower end, stomach and intestinal portion equal diameter; The anastomotic part diameter of anastomat structure front end is bigger, and size is basically all more than 24mm.
To high-order esophagus cervical region small space and special angle position, the application of existing anastomat in pars cervicalis esophagi carcinectomy treatment operation is very limited.Do not have to be directed against specially the anastomat of esophagus operation on neck in the market, use the anastomat of 21 models, 25 models to undergo surgery usually, according to human body difference; Sometimes anastomat anastomotic part diameter and human body esophagus cervical part of esophagus size are not complementary; Cause the esophagus mucosa to tear easily, thereby the slow or fistula of operative incision of healing, it is narrow etc. also to have the passage that coincide simultaneously; If but diameter diminish and the scope that can occur coincideing too small; The shortcoming that should not sew up, and existing anastomat is not with sealing effectiveness, so be not suitable in the esophagus cervical part of esophagus operation under the mirror of chamber.
This shows that existing anastomotic part of above-mentioned tube type anastomat and tube chamber inner assembly obviously still have inconvenience and defective, and demand urgently further improving in structure and use.How to found a kind of esophagus cervical part of esophagus special-purpose anastomat of performing the operation, real one of the current important research and development problem that belongs to.
Summary of the invention
The technical problem that this utility model will solve provides a kind of anastomotic part minor diameter and is the esophagus cervical part of esophagus anastomat on inclined-plane; Make it produce heavy in section anastomotic stoma; Be beneficial to the extension of anastomotic stoma, thereby overcome existing anastomat anastomotic part and the deficiency of coupling assembling in structure and use.
For solving the problems of the technologies described above; A kind of esophagus cervical part of esophagus of this utility model anastomat; Comprise nail supporting base assembly, nail bin groupware, bridge piece, fixed handle, flexible handle, propulsion plant, transmission component and adjusting device; It is characterized in that: described nail bin groupware and the corresponding surface of nail supporting base assembly inclined-plane, ovalize structure for coincideing each other; Described nail bin groupware is provided with dovetail groove, bridge piece one side that the dovetail groove near-end also is provided with the butt joint of a vertical slot and nail bin groupware be provided with nail bin on the match draw-in groove of locking of dovetail groove, and the boss that is complementary with vertical slot.
A kind of improvement as this utility model; Described nail bin groupware comprises nail bin, nail bin cover, endless knife, pushing slice of nail assembly and anastomosis staple; Wherein: the end face of nail bin, nail bin cover, endless knife, pushing slice of nail assembly is the inclined-plane that is parallel to each other; Endless knife is fixedly connected with the pushing slice of nail assembly, is installed in the nail bin cover.
Described nail bin groupware overall diameter is 17mm～21mm, and the nail bin groupware surface radially becomes a fixed angle with nail bin groupware.
Say further described nail bin groupware surface with its radially, and the nail supporting base assembly surface with its radially angulation be 15 °～50 °.
Described nail bin groupware overall diameter and bridge piece overall diameter are measure-alike, and nail bin groupware is connected with the buckle mode with bridge piece, guarantee smooth connection between nail bin groupware and the bridge piece.
Described bridge piece and fixed handle include left and right two parts, and left bridge piece and left fixed handle be structure as a whole, and right bridge piece and right fixed handle are structure as a whole.
Say further, be provided with 2-3 sealing member in the described bridge piece.
Described nail bin groupware surface and nail supporting base assembly surface both can be level and smooth inclined-planes, also can be made up of a plurality of horizontal bench that totally are the inclined-plane.
After adopting such design, this utility model provides a kind of esophagus cervical part of esophagus special-purpose anastomat, is applicable to undersized inclined-plane nail bin groupware structure; Produce heavy in section anastomotic stoma; Be beneficial to the extension of anastomotic stoma, the severe complications such as back fistula of operative incision, anastomotic stricture of avoiding performing the operation improve operation quality and success rate; Be beneficial to surgery recovery, therefore be more suitable for promoting the use of.
