Abstract

The utility model discloses a pair of surgical scissors for a digestive canal, which is composed of two sleeve rings (1) with fingers, a handle (2) and a blade (4), which are formed integrally through a centre shaft (3), wherein, the blade (4) is a curved blade, and the intersection angle between the extension line of the blade (4) and the curved part of the blade is alpha which is equal to 75-90 DEG, and the distance between the extension line of the blade (4) and the top end of the curved part of the blade is L which is equal to 4-6 cm. The utility model is suitable for cutting pelvic intestine and abdominal esophagus transversal profile in a small visual field. The utility model has the advantages of short abscission period, regular transversal profile, surrounding damage reducing, anastomotic stoma fistula reducing, and patient's pain reducing.

Description

Operation on digestive tract is cut

This utility model relates to a kind of shears, relates in particular to the operation on digestive tract of using when a kind of hospital surgery doctor operates to digestive tract and cuts.

In hospital, adopt Drug therapy usually for the higher rectal cancer of sickness rate, carcinoma of gastric cardia patient's treatment, radiotherapy and excision at present.Relatively surely belonging to excision can effect a radical cure the state of an illness, so generally adopt excision at patient's their early stage, the doctor needs a lot of medical apparatus and instruments such as pin when performing an operation excision, line, shears, gauze etc., present operating scissors blade portion is all crooked a little, its flexibility is little, be no more than 15 °, sweep length is all less than 4cm, this operating scissors is convenient at free tissue direct-view anatomical tissue, but be restricted when cutting off in the esophagus transverse section that low coverage is made the intestinal tube of pelvic cavity and abdominal part, because of the blade weak point, the operation doctor can only piecemeally cut, and makes the transverse section be difficult for cutting neatly, and the formation fistula of operative incision easily breaks in the gastrointestinal anastomosis, because the flexibility of shears is little, operates the doctor sometimes and have to go to cause very big misery to patient at operation shearing position Bie Laibie.

The purpose of this utility model provides a kind of low coverage that is more suitable for and makes the operation on digestive tract that the esophagus transverse section of the intestinal tube of pelvic cavity and abdominal part cuts off and cut, make the excision transverse section neat, easy to operate, operating time shortens, and reduces contingent damage and postoperative anastomotic fistula on every side.

The technical solution of the utility model realizes in the following manner:

A kind of operation on digestive tract is cut, it has finger sleeve ring (1), handle of a knife (2), blade (4) by two and forms one by axis (3), blade (4) is a curved blades, extended line of its blade (4) and the angle a=75-90 between the blade sweep °, distance L=4-6cm between the extended line of blade (4) and the blade sweep.

Distance between the crooked beginning of axis (3) and blade (4) is l-1.5cm.

Good effect of the present utility model is:

1, increased length after the blade bending, make and can wipe out that the transverse section after the excision is neat once when doing esophageal carcinoma, rectal cancer surgery excision, otch is easy to sew up, and shortens operating time.

2, increased the flexibility of shear blade, shears can directly stretch into place of incision when the esophagus that makes low coverage make the intestinal tube of pelvic cavity and abdominal part cut off, and avoided the operator to shear the position back and forth not and the damage surrounding tissue in operation, had reduced the complication of operation.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a main TV structure sketch map of the present utility model;

Fig. 2 is the side-looking structural representation of Fig. 1;

Fig. 3 is the plan structure sketch map of Fig. 1;

By Fig. 1-Fig. 3 as can be seen, this utility model is similar to common operating scissors, have finger sleeve ring 1, handle of a knife 2, blade 4 by two and form one by axis 3, blade 4 is curved blades, angle a=80 between the extended line of blade 4 and the blade sweep °, distance L=5cm between the extended line of blade 4 and the blade sweep top.Distance between axis 3 and the blade 4 crooked beginnings is l-1.5cm.

Claims

1, a kind of operation on digestive tract is cut, it has finger sleeve ring (1), handle of a knife (2), blade (4) by two and forms one by axis (3), blade (4) is a curved blades, it is characterized in that the extended line of blade (4) and the angle a-75-90 between the blade sweep °, distance L=4-6cm between the extended line of blade (4) and the blade sweep top.
