Abstract

The present invention belongs to the technical field of exercise tools for practising four skills of surgical knotting, suture, suture cutting and suture removal, which solves the technical problem that the surgical knotting, the suture, the sutrue cutting and the suture removal serve as important parts of basic operation, and at present, an efficient, easy and simple tool for practising after operations lacks in international range, and the present invention aims to fill the blank so as to rapidly and effectively improve the four skills in a short time. The present invention has the technical schemes that the present invention is composed of three accessories of a barrel body and an elastic band, two circular cloth blocks and two semicircular cloth blocks, wherein the edge of the outer diameter of each circular cloth block has six elastic bands at intervals, and the arc-shaped edge of each semicircular cloth block has three elastic bands at intervals. The barrel body and one accessory can be selected for practice when practicers practice at a time, the practicers sit in an upright sitting posture, a barrel port faces upwards, and the barrel body is clamped between the insides of the two knees for practising the basic operation.

Description

Surgical tube

Technical field

The present invention can effectively, simply practise surgery knotting, stitching, trimming, four technical ability of taking out stitches under operating-table.

Background technology

Surgery knotting, stitching, trimming, to take out stitches be the important component part of essential surgical skills. at present, lack in the world a kind of effectively, practice tools under the operating-table simply and easily. this project is intended to fill up this blank, so that in a short time, can improve these four technical ability rapidly, efficiently.

Summary of the invention

Surgical tube is made of cylindrical shell and adnexa.

Cylindrical shell: be cylindric, the thick about 0.1cm of barrel, high 12cm, the outward appearance diameter is 10cm, be fit to dress 6 (1/2) yards glove, 7 yards glove, 7 (1/2) yards glove, 8 yards glove and be subjected to shape. the horizontal plane apart from nozzle edge 2cm on the cylindrical shell has the equal circular hole of 6 spacings. and the sideline in they and the center of circle is divided into six an equal portions .6 circular hole along on downward every the vertical line of cylindrical shell 4 circular holes of 2cm apart being arranged with the circle at place, the diameter of all circular holes is 0.5cm, cylinder material is an irony, inside and outside lacquer adularescent lacquer. the cylindrical shell side all can be subjected to 5 kilograms of external force extruding indeformable.

Adnexa: be about one on the common rubber band of 12cm, diameter 0.2cm; Interior diameter 4cm, one of the circular cloth of overall diameter 8cm, there is the long rubber band of equidistant 6 treaty 5cm in cloth external diameter edge system; Two diameters are the semicircle cloth of 8cm, and on the every cloth curved edge being has three rubber bands of equidistant about 5cm. cloth has two kinds of thick about 0.2cm, 0.4cm, and cloth is closely woven by cotton yarn and forms, and cloth is white in color.

Description of drawings

Fig. 1 is a mode one: the knot that numeral among the figure 1 expression cylindrical shell, numeral 2 expression rubber bands, numeral 3 are illustrated on the cylindrical shell to be beaten;

Fig. 2 is a mode two: there is the cloth of the long rubber band of equidistant 6 treaty 5cm in the numeral 4 expression external diameter edge systems among the figure;

Fig. 3 is the inclined-plane in the mode three;

Fig. 4 is the vertical plane in the mode three;

Fig. 5 and Fig. 6 are mode four: wherein there is the cloth of three rubber bands of equidistant about 5cm in the 5 expression curved edge systems of the numeral among Fig. 5.

The specific embodiment

When once practising, can select for use cylindrical shell and a kind of adnexa to practise, the practitioner sits to get and sits up straight the position, and nozzle is made progress, and cylindrical shell is sandwiched in and carries out the essential surgical skills exercise between the two knee joint inboards.

Mode one, pass symmetric two holes on the same plane of cylindrical shell with a rubber band, rubber band is tightened slightly and is tied a knot fixing outside cylindrical shell, can select for use apart from nozzle 4cm, 6cm, four kinds of different degree of depth of 8cm, 10cm, silk thread is walked around rubber band and is carried out surgery knotting exercise. when rubber band position in the tube is dark, can not bimanualness in the tube, the practitioner can accomplish fluently unijunction outside tube, with forefinger or middle finger node is shifted onto on the rubber band, make two handss use force and ligation point point-blank, keep ligation point on rubber band, not move.

Mode two, the cloth that will have 6 rubber bands are put into cylindrical shell, rubber band passes the circular hole on the same plane, outer adjacent two rubber bands of tube are tightened and are tied a knot fixingly, make cloth be subjected to slightly retraction force of outside pull strength face, and the practitioner can carry out the surgical stapling exercise in cloth internal diameter edge.

Mode three, fixing means similar fashion two, difference are to make cloth to be fixed into an inclined-plane or the plane perpendicular to horizontal plane, to satisfy the surgical stapling exercise needs of practitioner to Different Plane.

Mode four, fixing means similar fashion two are with two identical cloths that respectively have three rubber bands of thickness, in level or oblique fixing and the tube, for the surgical stapling exercise on different depth plane or inclined-plane.

When different depth plane or inclined-plane carry out the surgical stapling exercise, can carry out trimming, the operation practice of taking out stitches.
