Abstract
The invention relates to a double-O-shaped anastomosis staple for an anastomat, which is an anastomosis staple forming structure for the anastomat and applicable to the anastomats. The double-O-shaped anastomosis staple for the anastomat consists of a staple leg and a staple crown, and is characterized in that the double-O-shaped staple leg is formed at the upper part of the staple crown. The forming width W of the anastomosis staple is 3-4mm, the forming height H of the anastomosis staple is 1.5-2.5mm, the length L of the staple crown is 2-3mm, and the forming radius R of the staple leg is 0.35-0.95mm. The diameter phi of the cross section of the anastomosis staple is 0.2-0.3mm. The double-O-shaped anastomosis staple for the anastomat forms the shape of B during the gastrointestinal peristalsis process and is firmer and difficult to be propped up; and the anastomosis staple can ensure the good blood supply at the anastomosis for a nutrition blood vessel, be conductive to healing of the anastomosis and be conductive to rehabilitation of a patient.
Description
Technical field
What the present invention relates to is a kind of double-O-shaped anastomosis staple for anastomat, is anastomat anastomosis staple molding structure, is applicable to anastomat usefulness.
Background technology
Anastomat normally utilizes between anastomosis cut component and nail anvil and steps up power at present, will treat that the osculating thickness of tissue is expressed to 1.5-2.5mm from about 4mm, the back percussion
Titanium silk anastomosis staple is shaped to " B " shape passing the osculating tissue.Yet in gastrointestinal wriggling process, " B " describes easily to be organized and struts in the short time, can cause the anastomotic stoma cracking, and formation coincide hemorrhage, fistula of operative incision; Even need the doctor to open the abdomen manual suture again, cause the patient suffering; Severe patient can operative failure.
Summary of the invention
The objective of the invention is provides a kind of double-O-shaped anastomosis staple for anastomat at above-mentioned weak point, and this anastomosis staple becomes " B " shape more firm in gastrointestinal wriggling process, is difficult for being strutted; By anastomosis staple, guarantee the good blood confession of anastomotic stoma to nutrient vessel, help anastomotic healing.
Double-O-shaped anastomosis staple for anastomat takes following technical scheme to realize: double-O-shaped anastomosis staple for anastomat is made up of nail lower limb, nail hat, forms two " O " staple lower limbs in the nail portion of labeling.Described anastomosis staple diameter of section Φ is 0.2～0.3mm, and described anastomosis staple forming width W is 3～4mm, and described anastomosis staple molding height H is 1.5～2.5mm; Described nail crown length degree L is 2～3mm, and described nail lower limb shaping radius R is 0.35～0.95mm.Operation principle:
The supporting use of double-O-shaped anastomosis staple for anastomat of the present invention and anastomat utilizes between anastomosis cut component and nail anvil and steps up power, will treat that the osculating thickness of tissue is expressed to 1.5-2.5mm from about 4mm, the back percussion
Titanium silk anastomosis staple is shaped to two " O " shapes passing the osculating tissue.
Double-O-shaped anastomosis staple for anastomat of the present invention utilizes between anastomosis cut component and nail anvil and steps up power, the back percussion
Titanium silk anastomosis staple is shaped to two " O " shapes passing the osculating tissue.Double-O-shaped anastomosis staple of the present invention becomes " B " shape more firm in gastrointestinal wriggling process, is difficult for being strutted; By anastomosis staple, guarantee the good blood confession of anastomotic stoma to nutrient vessel, help anastomotic healing, help patient's rehabilitation.
Description of drawings
The invention will be further described below with reference to accompanying drawing:
Fig. 1 is prior art anastomosis staple " B " formation type figure.
Fig. 2 is a sketch map after the rear distraction of prior art anastomosis staple " B " shape.
Fig. 3 is two " O " formation type figure of anastomosis staple of the present invention.
Fig. 4 is that two " O " formation types of anastomosis staple of the present invention strut back one-tenth " B " shape sketch map.
The specific embodiment
With reference to accompanying drawing 1,2, the present anastomat of prior art normally utilizes between anastomosis cut component and nail anvil and steps up power, will treat that the osculating thickness of tissue is expressed to 1.5-2.5mm from about 4mm, the back percussion
Titanium silk anastomosis staple is shaped to " B " shape and (sees accompanying drawing passing the osculating tissue
1)。Yet in gastrointestinal wriggling process, " B " describes easily to be organized and struts (seeing accompanying drawing 2) in the short time, can cause the anastomotic stoma cracking, and formation coincide hemorrhage, fistula of operative incision; Even need the doctor to open the abdomen manual suture again, cause the patient suffering; Severe patient can operative failure.
With reference to accompanying drawing 3,4, double-O-shaped anastomosis staple for anastomat is made up of nail lower limb 2, nail hat 1, and nail hat 1 top forms two " O " staple lower limbs 2 (seeing accompanying drawing 3).Described anastomosis staple diameter of section Φ is 0.2～0.3mm, and described anastomosis staple forming width W is 3～4mm, and described anastomosis staple molding height H is 1.5～2.5mm; Described nail crown length degree L is 2～3mm, and described nail lower limb shaping radius R is 0.35～0.95mm.Two " O " shape anastomosis staples of the present invention become " B " shape more firm in gastrointestinal wriggling process, are difficult for being strutted (seeing accompanying drawing 4).
Claims (5)
1. a double-O-shaped anastomosis staple for anastomat is made up of nail lower limb, nail hat, it is characterized in that forming two " O " staple lower limbs in the nail portion of labeling.
2. double-O-shaped anastomosis staple for anastomat according to claim 1 is characterized in that described anastomosis staple forming width W is 3～4mm, and anastomosis staple molding height H is 1.5～2.5mm.
