Abstract
The utility model discloses a membrane-covered interception reticular basket device comprising a guide wire, a manipulating device, a protective sheath tube and a reticular basket, wherein the guide wire and a framework of the reticular basket are fixedly combined together; the guide wire near the reticular basket is threaded by the protective sheath tube; the manipulating device is arranged at the tail part of the protective sheath tube and clasps the guide wire; the reticular basket is covered with a membrane and formed from the framework of the reticular basket and the membrane on the framework. The membrane-covered interception reticular basket overcomes the defects of serious wound, long recovery cycle, big gravel particle diameter and the like of the existing ureterolithotomy, enables the lithotripsy to be safer and more reliable, and has minimal wound and short recovery cycle after operation.
Description
Technical field:
This utility model relates to a kind of ureteral calculus rubble, stone taking device.It specifically is a kind of overlay film interception basket device.
Background technology:
The urinary system of human body is made up of kidney, ureter, bladder, urethra etc.Calculus is one of common pathological changes of urinary system.The traditional therapy of ureteral calculus has three kinds: a kind of method is an open surgery, although this operation can take out calculus, wound is big, it is many to lose blood, patient's restore cycle is long.Second method is the external stone crushing means, and this method gravel particle size is uncontrollable, and rubble stops up ureter easily.The third: adopt the interception basket of no film to carry out rubble, rubble that will be bigger draws in basket to avoid it to enter urinary catheter, this method is because the lack of uniformity of braiding process mesh, cause the rubble of some larger particles also to be retained in the ureter easily, cause suffering to the patient by mesh.
The utility model content:
Get shortcomings such as the stone operation wound is big, the restore cycle long, the gravel particle diameter is big in order to overcome existing ureter, this utility model provides a kind of overlay film interception basket device that big gravel particle can be effectively tackled in Wicresoft's rubble operation that is used for.
This utility model overlay film interception basket device comprises guide wire, actuation means, protection sheath pipe and basket, and described basket is the overlay film basket, is made up of basket skeleton and the thin film that is overlying on the basket skeleton.
Wherein, described guide wire and described basket skeleton are consolidated, and protection sheath pipe is set near on the guide wire of basket, and actuation means is positioned at the afterbody of protection sheath pipe and holds guide wire tightly.
In this overlay film interception basket device, described thin film covers and hangs over basket skeleton surfaces externally and internally.Described basket skeleton is formed by the nitinol alloy wire braiding, and described thin film is formed by the mode of soaking extension, apply by macromolecular material.
Adopt above scheme, overlay film interception basket of the present utility model is transported to basket in the ureter by Minimally Invasive Surgery, utilize laser to smash calculus, the calculus that granule is bigger is beneficial to continue rubble by the interception of overlay film basket and excretes by urethra to particle diameter safety, rubble interception efficient height has alleviated because of the bulky grain rubble and has entered the misery that causes in the catheter.
The utlity model has easy and simple to handlely, practical, operation wound is little, and the whole surgery process is controlled, loses blood thereby reduced postoperative, has promoted the rehabilitation as early as possible of patient's postoperative health.Reduced the time and the restore cycle of operation, postoperative complication is few.
Description of drawings:
Fig. 1 is the formation sketch map of overlay film interception basket device;
Fig. 2 is basket part-structure enlarged drawing in the overlay film interception basket device;
Fig. 3 is the sketch map of structure behind Fig. 2 basket overlay film;
Fig. 4 uses the back basket to draw the situation sketch map in for overlay film interception basket device.
The specific embodiment:
The overlay film interception basket device that this utility model provides, it is Nitinol basket of method braiding with shape memory function by braiding, method by overlay film deposits the silica gel thin film that one deck has good biocompatibility at the basket surfaces externally and internally then, reaches the purpose of interception rubble.
Referring to shown in Figure 1, be used for the rubble blocking apparatus of rubble Minimally Invasive Surgery, form by guide wire 1, actuation means 2, protection sheath pipe 3 and basket 4.Guide wire 1 is consolidated with basket 4, and protection sheath pipe 3 is set near on the guide wire 1 of basket 4, and actuation means 2 is positioned at the afterbody of protection sheath pipe 3 and holds guide wire 1 tightly.Overlay film interception basket of the present utility model belongs to this rubble blocking apparatus, and this part structure is identical with rubble interception basket device of the prior art, will not give unnecessary details.
In this utility model, referring to Fig. 2 and Fig. 3, basket 4 is the overlay film basket, is made up of basket skeleton 41 and the thin film 42 that is overlying on the basket skeleton 41, and basket skeleton 41 is to use the nitinol alloy wire braiding to form (as Fig. 2); Thin film 42 is the methods by overlay film, as soak extension, coating etc., at the film body (virgule is represented between as Fig. 3 skeleton) that basket skeleton 41 surfaces externally and internallies hang up, it has filled the some or all of space between the framework material, the rubble in the overlay film basket 4 is passed play second layer interception function.
Overlay film interception basket device of the present utility model can use like this: under endoscope, by Minimally Invasive Surgery basket is transported in the ureter, by rotating and promote actuation means, the overlay film basket can be released protection sheath pipe and expand to a spoonful shape (as Fig. 1), utilize laser to smash calculus this moment, the calculus that granule is bigger is tackled by the overlay film basket fully, at this moment the sustainable laser lithotripsy of using; After observing all gravel particles and all reaching safe diameter, backward rotation and twitch actuation means again, the overlay film basket can be contracted in the protection sheath pipe (as Fig. 4); The rubble of safe diameter can excrete by urethra, and the rubble process is finished.
It is skeleton that basket of the present utility model adopts nitinol alloy wire, through the special process knitting forming.In order to solve the mesh lack of uniformity that the braiding process occurs, adopt the method for special overlay film, as soak extension, coating etc.Macromolecular material is coated on the basket skeleton, and it has filled the some or all of space between the framework material.
More than describe as seen, owing to use overlay film interception basket device of the present utility model, overcome existing ureter and get shortcomings such as the stone operation wound is big, the restore cycle long, the gravel particle diameter is big, make the rubble operation safer, reliable, the operation process wound is little, and the post-operative recovery cycle is short.
