Description

A trocar hole stapler for laparoscopic surgery

technical field

The invention relates to the technical field of medical instruments, in particular to the suturing of the puncture hole of a 12mm trocar at the end of the laparoscopic operation.

Background technique

With the development of endoscopic technology and its wide application in the field of surgery, the concept of minimally invasive surgery has gradually gained popularity. Endoscopic technique is the cornerstone of minimally invasive surgery, and laparoscopic technique is one of the most commonly used endoscopic techniques. Compared with traditional open surgery, laparoscopic surgery has less trauma and faster postoperative recovery. In the process of laparoscopy, the pneumoperitoneum must be established first, and then a 5mm or 12mm operation hole should be opened in the abdominal wall with a trocar (hereinafter referred to as Trocar) at the appropriate site according to the surgical requirements. After the operation, these operating holes need to be sutured and closed. Some studies have reported that a series of related postoperative complications may occur if the Trocar puncture hole is not closed, such as infection and Trocar hernia. However, because the diameter of the Trocar puncture hole is about 10mm, it is very difficult to close the various layers of the abdominal cavity in such a narrow space, and it is even more difficult to operate in patients with obesity and other abdominal wall hypertrophy.

Therefore, it is very necessary to improve the current closing method of the Trocar hole, simplify the suturing method, and reduce postoperative complications.

Contents of the invention

The purpose of the present invention is mainly to provide a simple and practical puncture hole stapler for the technical problem of suturing and closing the puncture hole of the 12mm trocar during laparoscopic surgery.

Above-mentioned technical problem is mainly solved by following technical scheme:

A trocar hole stapler for laparoscopic surgery, comprising a cylinder with a diameter of 11 mm and a hemispherical cap 1, the lower end of the hemispherical cap 1 is connected to the slot at the top of the cylinder, and the bottom end of the hemispherical cap 1 is connected to the inside of the cylinder The push needle rod 3 is connected, and the end of the push needle rod 3 is provided with two branches to form an inverted Y shape; a pair of wire holes 6 are radially opened near the tail end of the cylinder, and a downwardly opening wire storage chamber 9 is provided at the tail end of the cylinder , the push pin part 7 is arranged in the cylinder; the two sides of the lower end of the hemispherical cap 1 are connected with the traction line 2, and the other end of the traction line 2 is connected with the push pin part 7 through the wire hole 6; , two suture needles 5 with thread are connected by absorbable thread 8, and the absorbable thread 8 is placed in the thread storage chamber 9 in a non-working state.

The push pin part 7 is a metal groove with a line.

The sewing needle 5 with thread is received in the cylinder under the non-working state, and is in contact with the two branches at the end of the needle push rod 3;

The tip of the sewing needle 5 with thread is provided with a barb.

The middle section of the cylinder is provided with a needle strip area 4, which is used to prevent the reverse movement of the threaded needle 5 after passing through it.

The advantages of a trocar hole stapler for laparoscopic surgery of the present invention are:

1. One line and two needles are preset in the circular cylinder, and the tissue puncture and suture can be completed under the working state, which is convenient and quick;

2. The front end of the pre-set needle has a barb, which cannot be withdrawn after entering the needle area, and it is easy to bring the needle out of the tissue to complete the suture;

3. Simple and practical structure, easy to use;

4. The present invention can greatly shorten the suturing time of the puncture hole and effectively reduce related complications.

detailed description

Below in conjunction with accompanying drawing, the present invention is further described: as shown in Figure 1-4, a kind of trocar hole stapler for laparoscopic surgery comprises the cylinder of diameter 11mm, and under non-working state, belt thread suturing needle 5 Received in the cylinder. The sewing needle with thread can be pushed away from the cylinder under the push of the needle push rod 3, and move along a predetermined track under the push of the push needle member 7. The bottom end of the push needle part 7 is slightly higher, and under the traction of the traction line 2, the push needle part 7 is driven to push the tail end of the sewing needle 5 with thread to break away from the cylinder.

Example:

The working principle of the device of the present invention is as follows: the tail end of the device of the present invention is inserted into the abdominal cavity through a 12mm Trocar. Exit the 12mmTrocar, and determine that the needle point of the device of the present invention is below the peritoneum after the needle pusher bar pushes the suture needle with thread out of the cylinder from the guide hole 6 on the side of the cylinder. Pull the device of the present invention outward to complete the puncture of the front and rear sheaths of the rectus abdominis; further pull the hemispherical cap at the head end of the cylinder, drag the traction line, pull the push needle, push the needle to complete the predetermined arc movement, and pull the belt The end of the sewing needle is pushed away from the cylinder. The end of the minute needle with thread penetrates into the strip area of the needle and cannot withdraw. At this time, the device is completely withdrawn from the abdominal cavity, and the suturing is completed.

Concrete method of use of the present invention is as follows:

After the laparoscopic operation is completed and before pneumoperitoneum is eliminated, the tail end of the device of the present invention is inserted into the abdominal cavity through a 12mm Trocar. Withdraw the 12mm Trocar, push the hemispherical cap 1 down on the push screw rod 3, and withdraw the threaded minute hand 5 from the cylinder by about 5mm. Now the minute hand 5 with line has been placed on the predetermined arc track. Pull the device of the present invention outward to complete the puncture of the anterior and posterior sheath of the rectus abdominis. Pull the hemispherical cap 1 at the head end of the cylinder, drag the traction wire 2, pull the push needle 7 through the wire hole 6, push the needle to complete the predetermined arc movement, and push the tail end of the sewing needle with thread away from the cylinder. After the threaded minute needle head end pierces into the needle strip zone 4, it cannot withdraw. At this time, the device is completely withdrawn from the abdominal cavity, and the suturing is completed.

The above description is the best embodiment of the present invention, and it is not intended to limit the present invention in any form. All simple modifications, equivalent changes and modifications made to the above examples according to the technical essence of the present invention still fall within the scope of the present invention. within the scope of protection.
