A kind of degradable two-way outer buckle-type intestinal is assisted stapling apparatus

Technical field:

This utility model belongs to surgical medical equipment technical field, is specifically related to the auxiliary stapling apparatus of a kind of degradable two-way outer buckle-type intestinal.

Background technology:

Take intestinal resection operation as example, and surgeon, after completing intestinal tube Partial Resection, need to connect intestinal tube two broken ends of fractured bone, to rebuild the seriality of intestinal tube.Usual way is to use classical anastomosis to carry out craft continuously or interrupted suture with silk thread or catgut; the manual method operation that coincide of this class is relatively time-consuming and complicated; anastomotic stoma mucosa is involutory be difficult for regular; and anastomotic stoma can not get effective protection among being often exposed to enteric cavity, there is the danger that causes postoperative anastomotic stoma seepage.The sixties in last century, surgical stapling device assembly has been invented by U.S. USSC company, closer, stapler, gastrointestinal tube type anastomat (EEA) etc. have released one after another, tube type anastomat provides double titanium tantalum peg, in intracavity, draw two broken ends of fractured bone cast tissues over to one's side stitching, thereby realized the mechanization of gastrointestinal anastomosis.The application of tube type anastomat has further expanded surgical operation scope, has shortened operating time, has reduced tissue injury and hemorrhage, has improved the safety of operation, utilizes tube type anastomat to complete coincideing of cast tissue and in modern surgery practice, popularizes gradually.But in clinical practice, we also find that tube type anastomat exists following some shortcomings: if anastomat is disposable equipment, price is more expensive; Operation sequence is more loaded down with trivial details, and not reproducible operation; Rectum is above cannot complete end to end anastomosis, needs the capable end-to-side anastomosis of closer, and closed rear stump forms blind pipe diverticulum, does not meet digestive tract physiological structure; Foreign body forever retains body and easily forms larger cicatrix; Children operation need be cautious use of or avoid to use; After anastomat coincide, anastomotic stoma still can not get effective protection, still has danger of seepage etc.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art; provide a kind of and can obviously accelerate the identical speed of intestinal; effectively protection anastomotic stoma is not subject to the pollution of intestinal contents; reduce anastomosis infectious-related complication, reduce the auxiliary stapling apparatus of degradable two-way outer buckle-type intestinal of the residual untoward reaction causing of foreign body in vivo.

The technical solution of the utility model: a kind of degradable two-way outer buckle-type intestinal is assisted stapling apparatus, comprise identical two identical parts of being made by high molecular degradable material, the strip locking pole that described identical part is connected with stake body with at least two one end by the stake body of a tubulose forms, described locking pole is uniformly distributed along stake body inner periphery, and its top is provided with the sealed key of barb-like elasticity in the slope; The inside and outside wall of described stake body is smooth, and end is hemispherical, is provided with the breach mutually suitable with the sealed key in locking pole top; Between described stake body and described locking pole, there is cannelure.

Further, described locking pole is four.

Further, the outer surface at described identical part is provided with medication coat.

Further, described medication coat comprises the medicine that develops under infection, promoting healing, antitumor and x-ray.

The beneficial effects of the utility model: 1. utilize compressed anastomosis principle to carry out intestinal wireless stitching, shortened operating time.2. can complete complete end to end anastomosis, keep the normal physiological structure of intestinal.3. before anastomotic healing, support plays and supports enteric cavity effect, has reduced the generation of anastomotic stricture.4. support has been isolated intestinal contents and anastomotic stoma, has avoided the direct effect of intestinal contents to anastomotic stoma, has reduced the generation of anastomotic leakage.5. be conducive to intestinal contents and freely pass through anastomotic stoma, shortened postoperative fasting time, be beneficial to function of intestinal canal and recover; 6. the auxiliary stapling apparatus of two-way outer buckle-type intestinal is prepared by degradable high polymer material, and the vivo degradation time is controlled, can not be detained in vivo and cause foreign body remaining.

Accompanying drawing explanation

The degradable two-way outer buckle-type intestinal of Fig. 1 is assisted stapling apparatus single-piece schematic diagram;

The auxiliary stapling apparatus combination of the degradable two-way outer buckle-type intestinal of Fig. 2 schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is elaborated.

As shown in Figure 1 and Figure 2, a kind of degradable two-way outer buckle-type intestinal is assisted stapling apparatus, comprise identical two identical parts of being made by high molecular degradable material polylactic acid, the strip locking pole 2 that described identical part is connected with stake body with at least two one end by the stake body 1 of a tubulose forms, described locking pole is uniformly distributed along stake body inner periphery, and its top is provided with the sealed key 3 of barb-like elasticity in the slope; The inside and outside wall of described stake body is smooth, and end is hemispherical, is provided with the breach 4 mutually suitable with the sealed key in locking pole top; Between described stake body and described locking pole, there is cannelure 5; Described locking pole 2 is four; Outer surface at described identical part is provided with medication coat; Described medication coat comprises the medicine that develops under infection, promoting healing, antitumor and x-ray.

To select corresponding intestinal to assist stapling apparatus according to intestinal tube diameter before use.Before intestinal canal anastomosis, intestinal tube two broken ends of fractured bone are made to purse string suture with absorbable thread respectively, two identical parts are imbedded in the intestinal tube of waiting to coincide, drawing pocket knotting in is fixed on locking pole 2, two devices are drawn close, staggered corresponding insertion of locking pole 2, locking pole 2 is subject to receive in thrust, until stake body 1 end indentation, there automatically springs open sealed, two ends intestinal tube is drawn close at assembly junction surface and the effect of being stressed is combined closely, and has coincide.If desired, intestinal tube placenta percreta is done to reinforce and is sewed up.

After the auxiliary stapling apparatus complete combination of degradable two-way outer buckle-type intestinal, between each locking pole, there is the space of certain width, in order to slough, fall into enteric cavity excretion.Due to the anastomotic stoma complete embedding of device that coincide, cut off contacting of anastomotic stoma and intestinal contents, formed the effect as enteral " short circuit ", intestinal contents can not pollute anastomotic stoma, thereby has effectively protected anastomotic stoma.In addition, this auxiliary device that coincide can be made different model, and the intestinal that meets all ages and classes patient, different parts coincide.
