Abstract

The utility model discloses an anastomotic head with a scarf tube for an anastomat of alimentary canal which is a medical appliance which can lead the cutting joint of a surgical operation for an alimentary canal to be completed for once. Because the cross section of a scarf tube type cutter and the center pole of an anastomat of alimentary canal form an angle of inclination with the degree of from 15 DEG to 45 DEG, the cross section of the cutting joint of a cutting edge and the shaft center of an alimentary canal also form an angle of inclination with the degree of from 15 DEG to 45 DEG after the surgical operation is completed, which enlarges the channel area of an anastomotic mouth, reduces the degree of obstruction which is generated because a scar shrinks at the anastomotic mouth, and lightens a patient's pain which is caused because the anastomotic part needs to be expanded or a second operation is needed because of the phenomenon of obstruction. Simultaneously the wound healing is firm, the haemostatic effect is good, the operation is convenient, the time of the operation is shortened, and the quality of the operation is improved.

Description

Anastomotic head with scarf tube for anastomat of alimentary canal

This utility model relates to a kind of identical fire of angle cast of digestive tract stapler, and it comprises pushing slice of nail, angle cast cutter, tantalum suturing nail, nail supporting base, center-pole, tool rest, nail seat outer housing.

Present medical digestive tract stapler, to formed alimentary tract anastomosis mouth cross section behind the capable surgical operation joint-cutting of digestive tract is to meet at right angles with the digestive tract axle center, again because of anastomat in digestive tract inside, so the diameter at anastomotic stoma place is just little many than the normal position of digestive tract, healing along with anastomotic stoma, scar tissue produces, because of it has the physiological property of contraction, the diameter at anastomotic stoma place will further be diminished, when particularly esophagus or these thinner digestive tract of small intestinal being undergone surgery, the contraction of postoperative anastomotic stoma is just more obvious, the time of blocking appearance also more early, anastomotic stricture is also very difficult in treatment, is that anastomotic stoma is expanded or operation all will bring very big misery to the patient once more.

The purpose of this utility model provides a kind of angle cast of digestive tract stapler identical head, and it can effectively enlarge the aisle spare of anastomotic stoma, reduces the generation that phenomenon is blocked at the anastomotic stoma place, alleviates because the misery that phenomenon is brought to the patient is blocked in generation.

The purpose of this utility model be achieved in that with the angle cast of digestive tract stapler coincide in the head angle cast cutter and relevant each in addition the cross section of part nail supporting base, tool rest, nail frame, nail seat outer housing manufacture with the center-pole angle less than 45 ° of ellipse garden tee sections greater than 15 °.

This utility model only need part and the vertical garden of center-pole tee section be changed system into and the ellipse garden type cross section of center-pole angle at 15 °～45 ° in addition in the identical head of existing digestive tract stapler each, so make simple, utilize that formed stitching cross section is the ellipse garden tee section that tilts behind the capable operation on digestive tract of this utility model, enlarged the aisle spare of anastomotic stoma, when the anastomotic stoma cicatrix produces contraction, the anastomosis also also has enough spaces to allow more food to pass through, avoid blocking phenomenon and produce, eliminated the patient and blocked the misery of bringing because of the postoperative digestive tract.

Figure one is the sketch map of the identical head of angle cast of digestive tract stapler, and (1) is that pushing slice of nail, (2) are that angle cast cutter, (3) are that tantalum suturing nail, (4) are that nail supporting base, (5) are that center-pole, (6) are that tool rest, (7) are that nail frame, (8) are nail seat outer housings.

Assembly angle cast cutter (2), nail supporting base (4) with identical of the angle cast of digestive tract stapler, tool rest (6), nail frame (7), the cross section of nail seat outer housing (8) manufactures the ellipse garden tee section with the same angle of center-pole (5) respectively, and its angle is 15 °～45 °.

Claims

1, the identical head of a kind of angle cast of digestive tract stapler, it comprises pushing slice of nail, angle cast cutter, tantalum suturing nail, nail supporting base, center-pole, tool rest, nail frame, nail seat outer housing, it is characterized in that the working sections of angle cast cutter, nail supporting base, tool rest, nail frame, nail seat outer housing becomes an inclination angle with the center-pole of digestive tract stapler.

2, the identical head of the angle cast of digestive tract stapler according to claim 1, the inclination angle that it is characterized in that working sections and center-pole can be 15 °～45 °.
