Abstract

The utility model discloses a heart artifical valve replacement wire fixing device. The utility model is made of non-poisonous drug soft rubber-plastic to form an integral structure, wherein, the lower part of the utility model is provided with a cylindrical ring structure; the upper part of the cylindrical ring structure is provided with an upward convex annular bar; a plurality of line inserting slots are arranged regularly on the annular bar; V-shaped slots are arranged on each of the line inserting slots. The utility model has the advantages of simple structure, reasonable structure, wiring specification, adjustable suture elasticity, convenient operation, and wide purpose. The utility model also has the advantages that the interlacement can be avoided and the time of an intracardiac operation can be shortened. The utility model is suitable for the suture of treatment of atrial septal defect, treatment of ventricular septal defect, and other surgical treatments.

Description

Heart artifical valve relacement wire fixing device

This utility model relates to medical instruments field, and especially the artificial cardiac valve prosthesis replaces suture and fixedly uses medical apparatus.

When carrying out artificial cardiac valve prosthesis's replacement operation at present, various suturess vise by operating forceps and are covered with on one's body the patient, during operation, basically entirely by doctor's technology and experience in the past, sew up, suture is arranged and is not had rule like this, take place easily to interlock, suture time is longer.

The purpose of this utility model provides a kind of suture wiring standard, does not interlock, and degree of tightness is adjustable, and can shorten operating time, and the artificial cardiac valve prosthesis who improves the operation benefit replaces stay suture fixator.

The purpose of this utility model is achieved through the following technical solutions.The artificial cardiac valve prosthesis replaces stay suture fixator, make by nontoxic soft moulding, this holder is an overall structure, the cylindrical circulus in bottom, one annular bar that raises up is arranged at the top of cylindrical annular structure, having on the annular bar manyly all has a V-type groove by regularly arranged rule seam at each rule seam place, and the both sides of cylindrical annular structure have two fixing holes respectively.

Owing to adopted technique scheme, make and the utlity model has following advantage: be simple and reasonable for structure, the wiring standard, can not interlock, easy to operate, the suture degree of tightness is adjustable, and can shorten the intracardiac surgery time, of many uses, also lack applicable to the chamber, the room lacks and other operating stitchings.

Below in conjunction with accompanying drawing this utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is an A-A cutaway view of the present utility model;

Fig. 4 is another example structure sketch map of the present utility model.

As we know from the figure, the artificial cardiac valve prosthesis replaces stay suture fixator, make by nontoxic soft rubber and plastic, this holder is an overall structure, the bottom of holder is a cylindrical annular structure 2, also can be semicircle ring-type or square ring-type or triangle circulus, cylindrical annular structure 2 can be hollow or solid.One annular bar that raises up 1 is arranged at the top of cylindrical annular structure 2, has manyly by regularly arranged rule seam 3 on the annular bar 1, and stitching 3 places corresponding to every rule on the annular bar 1 all has a V-type groove 4, so that suture embeds rapidly.The both sides of the cylindrical annular structure 2 of holder bottom have two fixing holes 5 respectively.

Its operation principle is as follows: during operation, fixing band is fixed on the patient affected part by the fixing hole 5 of holder lower cylindrical shape circulus 2 both sides with holder, various suturess are embedded in the rule seam 3 by the V-type groove 4 on the annular bar 1, make the well-regulated as required arrangement of various sutures, and can stitch 3 degrees of tightness of regulating suture effectively by rule, the doctor just can conveniently sew up exactly like this, and unlikely appearance is staggered, and can shorten the time of intracardiac surgery.

Claims
