Description

Multifunctional Surgical Stapler

technical field

The utility model relates to the technical field of medical instruments, in particular to a multifunctional surgical stapler.

Background technique

The traditional stapler is needle-shaped, which includes a button, a grasper and an outer sleeve. By pressing the button, the grasper extends out of the outer sleeve and opens the jaws to grab the suture. However, the diameter of this stapler is relatively thick, which cannot meet the needs of some operations, that is, it has poor versatility, especially for uterine surgical suture after caesarean section. The surgical suture method for controlling postpartum hemorrhage reported by the hospital is simple and easy to implement. During the operation, it is necessary to suture the uterus on the front and back walls of the uterus to prevent bleeding caused by uterine atony, so as to avoid hysterectomy, which is beneficial to the preservation of the uterus. reproductive function. In particular, it is easy to cause bleeding after puncturing with this suture, and the resulting puncture hole has a large diameter, greater than or equal to 4 mm, and it is impossible to stop the bleeding by filling the puncture hole with indwelling sutures.

Utility model content

Based on this, it is necessary to provide a multifunctional surgical stapler in view of the problems of poor versatility of the stapler and easy bleeding after puncturing.

A multifunctional surgical stapler comprising:

The outer sleeve is provided with a sleeve hole passing through in the axial direction, the outer sleeve includes a sleeve body and a limit portion connected to each other, and the sleeve hole includes a first part opened in the sleeve body and a sleeve opened in the limit. the second part of the part;

A puncture needle, comprising a puncture portion and a grip portion connected to the puncture portion, the diameter of the grip portion is larger than the diameter of the puncture portion, the diameter of the puncture portion is not greater than the diameter of the sleeve hole, the The puncturing part is used for piercing through the sleeve hole during the puncturing operation; the diameter of the gripping part is larger than the diameter of the limiting part; the limiting part is used to limit the gripping part;

A collar, comprising a collar body and a tightening portion extending outward from the collar body, the diameter of the collar body is larger than the diameter of the sleeve hole, and the tightening portion is used to pass through the sleeve hole Inside.

In the above-mentioned multifunctional surgical stapler, the sleeve hole includes a first part opened in the sleeve body and a second part opened in the limiting part. Since the diameter of the gripping part is larger than the diameter of the puncturing part, the diameter of the puncturing part is smaller than or equal to the sleeve. The diameter of the hole makes the puncture part slide in the first part and the second part of the sleeve hole, and because the diameter of the grip part is larger than the diameter of the stop part, the diameter of the grip part is larger than the diameter of the sleeve hole, so that the grip part is larger than the diameter of the sleeve hole. The piercing part is limited by the limiting part, which prevents the gripping part from sliding out of the sleeve hole through the first part and the second part in turn during the piercing operation, and it is also convenient for the user to better grip the gripping part; During the suturing operation, the user first passes through the puncture part of the puncture needle into the sleeve hole; then moves the suturing device to the target position, such as the uterus of the parturient; and then holds the limit part or the sleeve body with one hand, The other hand holds the grip part tightly and pushes the grip part to move relative to the limit part, so that the grip part drives the puncture part to move, so that the puncture part slides in the sleeve hole to perforate at the target position to be punctured.
