Description

A ligation positioning guide for laparoscopic surgery

technical field

The utility model relates to laparoscopic surgery, in particular to a ligation positioning guide for laparoscopic surgery.

Background technique

At present, in laparoscopic surgery, double ligation is often used in the proximal segment of vessels below φ5mm, and the distance between the two ligation lines is often required to be greater than 1mm. However, due to the short free blood vessels, the distance between the second ligation line and the first ligation line Distance control is often not ideal, and the second ligature can slip into the depression where the first ligature was placed, rendering the second ligature ineffective. At present, separating forceps or other grasping instruments are commonly used to grasp the ligature to control the distance between two ligatures. This positioning method is not precise enough and relatively not safe enough. In addition, during the process of knotting, the relative cross force between the knot pusher and the ligature may cause the risk of excessive stretching and rupture of the blood vessel. If there is an instrument to fix the blood vessel when making the knot, it will make the knot safer; cut off after the ligation is completed When ligating the thread, it is necessary to pull the ligating thread to form a certain angle with the scissors to facilitate cutting. At present, instruments such as separating forceps are used to hold the ligating thread, which is often not light and convenient in actual operation. The lightweight and safe equipment improves work efficiency.

Utility model content

The technical problem to be solved by the utility model is to propose a ligation positioning guide for laparoscopic surgery in view of the above shortcomings of the prior art. tasks, improve work efficiency, and reduce surgical risks.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is achieved in the following manner: a ligation positioning guide for laparoscopic surgery, including a guide head body, one end of the guide head body and a middle position is provided with a guide for guiding the ligature wire The first arc groove, the first arc groove is surrounded by an arc surface, the other end of the guide head body is provided with a mounting seat, the mounting seat is provided with a connecting rod, and the end of the connecting rod away from the mounting seat is provided with a handle, the handle is connected to the mounting seat. The connecting rods are connected by circular arc segments; the lower end surface of the guide head body is provided with a second circular arc groove placed on the surface of the blood vessel.

In this way, blood vessels need to be ligated during laparoscopic surgery, and the ligature can be collected conveniently through the first arc groove on the positioning guide without affecting the pressure of the knot pusher to tighten the knot, and by moving the guide head body , so as to move the position of the ligation thread in the blood vessel, and quickly and accurately push the ligation thread to the ligation point, which greatly improves the doctor's work efficiency. The second arc groove placed on the surface of the blood vessel, the size of the second arc groove matches the blood vessel, increases the contact area between the second arc groove and the blood vessel, reduces the damage to the blood vessel caused by the positioning guide, and the surface of the positioning guide Both are processed with rounded corners, which greatly avoids damage to blood vessels or other tissues. At the same time, they can relatively fix the blood vessels, prevent excessive pulling, and improve the safety and reliability of the positioning guide; The first arc groove pulls the ligature to any angle, which is convenient for doctors to cut the line and improves work efficiency.

The technical scheme that the utility model is further limited is:

The aforementioned ligation positioning guide for endoscopic surgery is provided with a third arc groove at the end of the guide head body close to the mounting seat, and the minimum distance between the third arc groove and the first arc groove is 1-5mm. The third arc groove can conveniently determine the ligature point. When two or more ligature points need to be made, it is not easy to operate due to the small distance between the ligature points, but it can be realized by using the first arc groove and the third arc groove. Quickly find the ligation point, and there is a certain distance between the third arc groove and the first arc groove, avoiding two or more ligation points from gathering together, improving the doctor's work efficiency, and performing ligation quickly and accurately.

In the aforementioned ligation positioning guide for endoscopic surgery, the mounting base is provided with a threaded hole, one end of the connecting rod is provided with a threaded rod matching the threaded hole, and the threaded rod is sleeved with at least one angle for adjusting the angle between the connecting rod and the mounting seat. The spacer sleeve, because the size of the connecting rod and the mounting seat is small, the angle between the handle and the connection is changed by using the spacer sleeve, the operation is convenient, the cost is low, the flexibility of use is improved, and the operation is suitable for different conditions.

In the aforementioned ligation positioning guide for laparoscopic surgery, the diameter of the second arc groove is φ5-φ7mm, and the arc length of the second arc groove is 1/3 of the circumference.

The beneficial effects of the utility model are: in the process of endoscopic surgery, the blood vessels need to be ligated, and the first arc groove on the positioning guide can conveniently collect the ligation thread, without affecting the pressure of the knot pusher to tighten the knot. And by moving the guide head body, the position of the ligature line in the blood vessel is moved, and the ligature line is quickly and accurately pushed to the ligation point, which greatly improves the doctor's work efficiency. The lower end of the guide head body is provided with a second arc groove placed on the surface of the blood vessel. The size of the second arc groove matches the blood vessel, which increases the contact area between the second arc groove and the blood vessel and reduces the damage of the positioning guide to the blood vessel. , and the surface of the positioning guide is rounded, which greatly avoids damage to blood vessels or other tissues. When the thread needs to be trimmed, the ligature thread can be pulled to any angle through the first arc groove or the third arc groove, which is convenient for doctors to trim the thread and improve work efficiency; setting the third arc groove can conveniently determine the ligation point. or multiple ligature points, due to the small distance between the ligature points, it is not easy to operate, but the first arc groove and the third arc groove can be used to quickly find the ligature point, and the third arc groove and the first arc groove There is a certain distance between the grooves, which prevents two or more ligation points from gathering together, improves the doctor's work efficiency, and performs ligation quickly and accurately.
