Abstract

The utility model discloses an esophageal stump girdling knife, which comprises two symmetrical girdling blades and a scissors-like knife rest, wherein the lower ends of the two girdling blades are respectively fixed on two front end faces of the scissors-like knife rest through screws, so that the two girdling blades are vertical to the scissors-like knife rest; the edges of the two girdling blades are arc-shaped, and the radius of each girdling blade is as same as that of a connecting rod on a nail bin base; and when the scissors-like knife rest is closed, the edges of the two girdling blades are closed and tightly attached to the outside wall of the connecting rod. The utility model has the advantages that the esophageal stump girdling knife is simple in structure, reliable, durable, convenient to process and economical in cost, is used and operated as scissors, is easy to master and can efficiently and quickly treat an esophageal stump; and the edges are smooth, so the girdling knife is favorable for improving the surgical quality.

Description

The esophageal stump girdling cutter

Technical field

This utility model relates to the esophageal stump girdling cutter that uses in a kind of Resection of Esophageal Carcinoma, belongs to medical instruments field.

Background technology

In Resection of Esophageal Carcinoma, use anastomat and carry out in the reconstruction of digestive tract process, remove BIAO and BEN after; Esophageal stump must fitly cut off, and typically uses operating scissors at present in the operation and prunes esophageal stump, and the surgeon cuts a circle with operating scissors bit by bit round the connecting rod of nail bin base and could esophagus be cut off; Because the space is narrow and small, such operation is very inconvenient, has both delayed operating time; And the clip section is difficult for pruning concordant, the identical quality of influence.

For this reason, number of patent application is 201010230323.1 to attempt to adopt the mode of ring cutting to solve the problem that esophagus is sheared inconvenience with 201020262964.0 esophageal stump girdling device (two patent contents are identical), though this thinking is pretty good; Yet; The structure that this esophageal stump girdling device designed is too complicated, considers from the manufacturing process angle, 1 centimeter of ring cutting diameter less than; It is very large accomplishing the structure difficulty that the designer designed on the scale of construction tiny apparatus like this; Promptly enable to create, its processing cost will be very uneconomical, and too the structure of sophisticated makes that also reliability, the ruggedness of its use can not get guaranteeing.

Summary of the invention

For solving the problems referred to above that prior art exists, this utility model provides a kind of esophageal stump girdling cutter of features simple structure, and its technical scheme of taking is:

This circular cutter comprises the ring cutting blade and cultrates knife rest; The ring cutting blade is symmetric two, and their lower end is fixed on two front end faces of the knife rest of cultrating through screw respectively, makes two ring cutting blades vertical with the knife rest of cultrating; The edge of a knife of two ring cutting blades is circular arc; And its radius is identical with connecting rod radius on the nail bin base, and when the knife rest of cultrating closed up, the lateral wall of connecting rod is crowded around and be close to the edge of a knife of two ring cutting blades.

This circular cutter utilizes the principle of cutting (but not shearing) that esophageal stump is cut off by the support of metal connecting rod, and the ring cutting blade is detachable, is convenient to change when rust, and the knife rest of cultrating then can use behind the cleaning and sterilizing repeatedly.Therefore the utility model has the advantages that simple in structure, reliability and durability, easy to process, cost economy uses operation as using shears, easy master, it is efficiently quick to handle esophageal stump, and otch is smooth, is beneficial to improve the operation quality.

Description of drawings

Fig. 1 is the structural representation of this utility model;

Fig. 2 is the installation diagram of this utility model ring cutting blade with the knife rest of cultrating;

Fig. 3 is strapped in the sketch map on the nail bin base for esophageal stump to be cut.

The specific embodiment

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

As depicted in figs. 1 and 2; Ring cutting blade 1 is symmetric two, when processing and fabricating, can process sharp blade easily like this with reference to the material and the thickness of scalpel; Their lower end is fixed on two front end faces of the knife rest 2 of cultrating through screw 3 respectively in opposite directions; Make two ring cutting blades 1 vertical with the knife rest 2 of cultrating, the edge of a knife of two ring cutting blades 1 is circular arc, and its radius is identical with connecting rod 5 radiuses on the nail bin base 4; When the knife rest 2 of cultrating closed up, the lateral wall of connecting rod 5 is crowded around and be close to the edge of a knife of two ring cutting blades 1.

As shown in Figure 3, nail bin base 4 is inserted in the esophagus 6 with fixed thereon connecting rod 5, when using this circular cutter; The hand-held knife rest 2 of cultrating; As the biconditional operation shears, the handle of the knife rest 2 of separately cultrating opens two ring cutting blades 1 and aims at the position 8 that will excise, clutches the knife rest 2 of cultrating afterwards and makes ring cutting blade 1 cutting esophageal stump 7; Also can rotate this circular cutter simultaneously; Cut off esophagus so more easily, operate all the other positions to be cut of cutting then equally, up to esophageal stump 7 is cut off fully.

Claims

1. esophageal stump girdling cutter; Comprise ring cutting blade (1) and the knife rest of cultrating (2); It is characterized in that: ring cutting blade (1) is symmetric two, and their lower end is fixed on two front end faces of the knife rest of cultrating (2) through screw (3) respectively, makes two ring cutting blades (1) vertical with the knife rest of cultrating (2); The edge of a knife of two ring cutting blades (1) is circular arc; And its radius is identical with connecting rod (5) radius on the nail bin base (4), and when the knife rest of cultrating (2) when closing up, the lateral wall of connecting rod (5) is crowded around and be close to the edge of a knife of two ring cutting blades (1).
