Description

Puncture outfit for assisting fascia suture

Technical Field

The utility model relates to the field of medical equipment, especially a puncture outfit for assisting fascia suture.

Background

Currently, with the continuous development of minimally invasive surgical techniques in medicine, more and more open abdominal surgeries are converted into laparoscopic minimally invasive surgeries. In clinical minimally invasive abdominal surgery, an operation channel for entering and exiting from the outside into and from the abdominal cavity is usually required to be established, surgical instruments are operated outside the abdominal cavity, and operations such as exploration, electrocoagulation, hemostasis, tissue separation and incision, suturing and the like are performed on pathological tissues by means of the channel. Meanwhile, the suture should be sutured as soon as possible after the operation, a better suture effect is ensured, and the risks of wound infection, pathological changes, hernia and the like are reduced.

Therefore, in order to avoid the risk complications and the like described above after the operation as much as possible, the tissue is usually furled and percutaneously sutured using a minimally invasive fascia closer at the end of the operation. However, such suturing methods involve switching between the surgical channel and the closure device, which not only results in cumbersome operation and increases the workload of medical staff, but also easily causes secondary injury to the wound of the patient and causes bleeding due to the fact that the channel is pulled out and the closure device is reinserted.

Disclosure of Invention

An object of the utility model is to provide a supplementary manadesma sutural puncture ware guarantees that the postoperative can be under the condition of not damaging the wound and not increasing the infection risk, convenient and sew up fast and guarantee good effect of sewing up.

The purpose of the utility model is realized through the following technical scheme: a puncture outfit for assisting fascia suture comprises a puncture needle, a puncture sheath and a puncture outfit; the puncture sheath comprises a sheath tube and a sheath tube seat, a sealing cover is arranged at the upper opening of the sheath tube seat, a puncture hole for inserting a puncture needle is formed in the middle of the sealing cover, two guide holes for inserting a puncture needle are formed in the sealing cover respectively, the two guide holes are arranged in a staggered mode in an inclined mode, and guide windows corresponding to the two guide holes one to one are formed in the side wall of the sheath tube; the inlet of the guide hole is positioned on the upper side surface of the sealing cover, and the extension line of the outlet of the guide hole passes through the corresponding guide window.

Compare prior art, the utility model has the advantages of:

1. the establishment and the closing of a minimally invasive surgery channel can be simultaneously met;

2. the puncture and the closing function are integrated, the resource is saved, and the product is matched to facilitate the operation.

Detailed Description

The invention is described in detail below with reference to the drawings and examples of the specification:

fig. 1 to 13 are schematic views illustrating an embodiment of a puncture instrument for assisting fascia suture according to the present invention.

A puncture outfit for assisting fascia suture comprises a puncture needle 1, a puncture sheath 2 and a puncture outfit 3;

the puncture sheath 2 comprises a sheath tube 2-1 and a sheath tube seat 2-2, a sealing cover 2-3 is arranged at the upper opening of the sheath tube seat 2-2, a puncture hole 2-6 for inserting the puncture needle 1 is formed in the middle of the sealing cover 2-3, two guide holes 2-7 for inserting the puncture device 3 are formed in the sealing cover 2-3 respectively, the two guide holes 2-7 are arranged in an obliquely staggered mode, and guide windows 2-4 corresponding to the two guide holes 2-7 in a one-to-one mode are formed in the side wall of the sheath tube 2-1;

the inlet of the guide hole 2-7 is positioned on the upper side surface of the sealing cover 2-3, and the extension line of the outlet of the guide hole passes through the corresponding guide window 2-4.

A single-layer or multi-layer sealing ring is arranged in the sealing cover 2-3, the single-layer structure is a complete O-shaped sealing ring, and the multi-layer structure is formed by overlapping and combining 4-5 fan-shaped sealing valves.

And sealing films are arranged on the guide windows 2-4.

And an air injection valve 2-5 is arranged on the side wall of the sheath tube seat 2-2.

The upper end of the puncture needle 1 is provided with a puncture needle seat 1-1, and the puncture needle seat 1-1 is detachably connected to a sheath tube seat 2-2 or a sealing cover 2-3.

The lower end of the puncture needle 1 is provided with a puncture needle head 1-2.

The puncture device 3 comprises a cylindrical main body 3-1, a needle tube 3-2 fixedly arranged at the front end of the cylindrical main body 3-1, a puncture needle 3-3 arranged in the needle tube 3-2 and a push handle 3-4 used for driving the puncture needle 3-3 to stretch back and forth.

The working principle of the utility model is as follows:

after the puncture needle 1 and the puncture sheath 2 are combined into the puncture outfit, the puncture outfit is placed into the body from the outside of the body through a prefabricated wound (the depth of the puncture outfit is that the guide window 2-4 is completely submerged under the skin tissue), and the figure 7 is shown.

Then the puncture needle 1 is taken out through the puncture needle seat 1-1, and CO is injected by utilizing the air injection valve 2-5₂The abdominal cavity is brought into a "pneumoperitoneum" working environment, see fig. 8.

The surgical instrument 4 can then be used to perform a minimally invasive surgical procedure through the puncture sheath 2 channel, see fig. 9.

After the operation is completed, the surgical instrument 4 is taken out, one end of the surgical suture is clamped by the puncture needle 3-3 of the puncture device 3, the surgical suture is placed into the body through any one of the guide holes 2-7 and then released, and the puncture device 3 is withdrawn (the sealing membrane, the tissue, the peritoneum and the like need to be punctured when passing through the guide window 2-4), which is shown in fig. 10.

The surgical suture is brought out of the body by the lead-through 3 entering the body through another guiding hole 2-7, see fig. 11.

The puncture sheath 2 is slowly withdrawn until it is separated from the suture, and knotting and suturing are performed to complete the final stage of the operation, see fig. 12-13.
