Description
Technical field
The present invention relates to medical operating articles for use technical field, belong to a kind of pancreas and break end protective cover.
Background technology
Pancreatoduodenectomy (pancreaticoduodenectomy, PD) is treatment Diseases In Pancreatic Head, courage
House steward lower end, duodenofiberscope, the main method of duodenal cancer, complete in general larger medical mechanism year
More than PD 200 example.PD performs the operation complexity, and postoperative complications are many, wherein comes from pancreas intestines or pancreas stomach previous anastomotic causes
Leakage (fistula) person is most commonly seen and serious for pancreas.The harmfulness of pancreas leakage is that the pancreatin that courage intestinal juice activates leaks into abdominal cavity,
Corrosion and digestion surrounding tissue, cause fatal massive haemorrhage or uppity infection, ultimately result in patient dead
Die.Therefore since PD carries out, surgery scholar all explore method of alimentary tract reconstruction, especially pancreas intestines or
Pancreas stomach anastomosis, it is intended to reduce, even stop pancreas intestines or the generation of pancreas stomach anastomotic leakage.Currently mainly should
Anastomosis include that pancreas Surgical healing and pancreas stomach coincide.Either Pancreas to stomach anastomosis, or Pancreaticoenterostomy
In, in addition to ductus pancreaticus is identical to gastric mucosa or jejunal mucous membrane is coincide by ductus pancreaticus, other methods of anastomosis such as sleeve type
Or Binding pancreatico-jejunostomy, (these methods of anastomosis are clinical required for plug-in type or cluster Pancreas to stomach anastomosis
The pancreas method of alimentary tract reconstruction used), pancreas stump all directly contacts with gastric juice or intestinal fluid.Pancreas stump
Having from the horizontal blood vessel of pancreas, spleen blood vessel, branch's supply blood supply etc. of the left blood vessel of stomach, these blood vessels are at Laparoscopic distal
During You Li, what externa had has been partially damaged, and therefore the corrosion of hydrochloric acid in gastric juice or intestinal fluid will increase
The possibility that the broken ends of fractured bone of these blood vessels or blood vessel is hemorrhage, owing to the pancreas broken ends of fractured bone is in gastral cavity or enteric cavity, so not
Being same as intraperitoneal hemorrhage, this hemorrhage clinical manifestation is UGB, owing to being all bigger blood vessel
Hemorrhage, often in hemorrhage urgency, amount is big, and blood vessel corrodes, and clinical signs is to digest on Post operation occurs suddenly
Gastrointestinal hemorrhage, quickly haemorrhagic shock, in critical condition, need emergency operation, but just accepted pancreas due to patient
The major operation of gland, overall recovery is poor, it tends to be difficult to the strike that tolerance is performed the operation again.Therefore, this situation is
Clinical Pancreas to stomach anastomosis or Pancreaticoenterostomy bring the biggest risk.Also this modus operandi has been had a strong impact on
Application.And pancreas stump and gastral cavity be environmentally isolated the rational side being to avoid above-mentioned complication that comes
Method.Current pancreas stomach coincide or after Pancreaticoenterostomy, and the pancreas broken ends of fractured bone lacks protection, easily by gastric juice or small intestine
Corrosion, the pancreas broken ends of fractured bone is susceptible to massive haemorrhage, needs again to perform the operation, even threat to life.
Summary of the invention
It is an object of the invention to provide a kind of pancreas to break end protective cover, its simple in construction, easy to use, effect
Significantly, pancreas stump can be come with being environmentally isolated of gastral cavity, it is to avoid the generation of complication, can effectively protect
Protect the pancreas broken ends of fractured bone, be allowed to avoid contacting with gastric juice or the direct of intestinal juice.
For achieving the above object, the present invention takes techniques below scheme:
A kind of pancreas breaks end protective cover, and this protection set is truncated conical shape, and the inner of this protection set is closed,
The outer end of this protection set is opening-like, and this protection set includes inner sleeve and overcoat, and described inner sleeve uses poly-third
Alkene material is made, and described overcoat uses polytetrafluoroethylmaterial material to make.
Abdominal viscera contact surface uses clinic wide variety of polytetrafluoroethylmaterial material on sticking patch, raw
Thing compatibility is good, it is to avoid cause abdominal viscera adhesion, simultaneously in the face of the face patching material poly-third of the pancreas broken ends of fractured bone
Alkene.
Bent inwards flanging in the openend of protection set, is provided with medical nylon rope, this medical Buddhist nun in flanging
Dragon rope is drawn from flanging, strains medical nylon rope and makes flanging in tightening up shape.
Tighten up with the similar pre-knotting receiving limit at the snare of flanging, it is simple under laparoscope or Leonardo da Vinci robot pancreas
Gland operation application.
Described inner sleeve and overcoat are complex as layer of material, and internal layer is polypropylene material, and outer layer is polytetrafluoroethyl-ne
Alkene material.
The length of protection set is 2.5cm, and diameter is 3cm.
A kind of pancreas breaks end protective cover, and this protection set is truncated conical shape, and the inner of this protection set is closed,
The outer end of this protection set is opening-like, and this protection cover material is that biomaterial takes off cell small intestinal submucosa
(small intestinal Submocosa)。
Bent inwards flanging in the openend of protection set, is provided with medical nylon rope, this medical Buddhist nun in flanging
Dragon rope is drawn from flanging, strains medical nylon rope and makes flanging in tightening up shape.
Tighten up with the similar pre-knotting receiving limit at the snare of flanging, it is simple under laparoscope or Leonardo da Vinci robot pancreas
Gland operation application.
The length of protection set is 2.5cm, and diameter is 3cm.
A kind of pancreas breaks end protective cover, and this protection set is truncated conical shape, and the inner of this protection set is closed,
This protection set outer end opening-like, this protection cover material be biomaterial be the pericardium of pig and ox.
Bent inwards flanging in the openend of protection set, is provided with medical nylon rope, this medical Buddhist nun in flanging
Dragon rope is drawn from flanging, strains medical nylon rope and makes flanging in tightening up shape.
Tighten up with the similar pre-knotting receiving limit at the snare of flanging, it is simple under laparoscope or Leonardo da Vinci robot pancreas
Gland operation application.
The length of protection set is 2.5cm, and diameter is 3cm.
The invention has the beneficial effects as follows: its simple in construction, easy to use (can be applicable to abdominal, abdomen
Endoscope-assistant surgery, Leonardo da Vinci's robotic surgical device's pancreatic surgery), effect notable, can by pancreas stump and gastral cavity or
Enteric cavity is environmentally isolated and comes, and effectively the protection pancreas broken ends of fractured bone, is allowed to avoid contacting with gastric juice or intestinal juice, thus keeps away
Exempt from pancreas stump to be corroded by gastric juice or intestinal juice, cause the complication such as mortality massive haemorrhage.
