Description

A postoperative suture-free drainage device

technical field

The invention relates to the technical field of medical devices, in particular to a postoperative suture-free drainage device.

Background technique

Clinical application Drainage system Drainage of fluid, digestive juice, excrement and pus is one of the main tasks of surgery. Surgical drainage is to export the above-mentioned liquid accumulated between human tissues or body cavities out of the body to control infection, promote wound healing, and reduce surgery. Post-complications, relief of discomfort caused by fluid mass effect.

With the development of minimally invasive techniques, laparoscopic choledocholithotomy and T-tube drainage for the treatment of hepatolithiasis has become a routine procedure in hepatobiliary surgery. The bile duct wall was sutured, and the peritoneal drainage tube was placed on the wound to cooperate with drainage, so as to reduce and prevent postoperative complications. Laparoscopic suturing technique is one of the key points for the success of this operation. For some patients with severe bile duct wall inflammation and a bile duct wall thickness of more than 3mm, laparoscopic suturing is more difficult, and there is a very high postoperative bile leakage without suturing. Possibility, non-conventional suture will lead to a variety of short-term and long-term accidents and complications after surgery, increasing the pain of patients and the cost of hospitalization. Having drainage tubes at two places on the body wall after the operation brings more inconvenience and pain to the patient. Multiple drainage tubes also increase the chance of tube detachment after the operation. The recovery is slow, and in the long run, the skin at the drainage site will be unsightly.

To sum up, the existing patients with severe inflammation of the bile duct wall need intubation and drainage after the operation, and after the operation, two drainage tubes need to be placed on the body wall. After the operation, the two intubations on the body of the patient will affect each other , it will double the postoperative pain of the patient, and it will also increase the chance of tube detachment. In addition, after the postoperative drainage tube is issued, the inflammatory scars on the two parts of the patient's body where the drainage tube is placed are very obvious, resulting in a longer recovery period for the patient after surgery. Long, two drainage scars, in the long run, the skin of the drainage area will be unsightly, and it is very difficult to suture the bile duct wound, and the operation difficulty is very high.

The two bends are equally spaced, and there are several drainage holes 7 at the tail end of the auxiliary pipe 8 and the upper branch pipe 6. The several drainage holes 7 are distributed at equal intervals on the sides of the auxiliary pipe 8 and the upper branch pipe 6, and the circumference of the drainage main pipe 2 is 18～22F, the circumference diameter of the upper branch pipe 6 is 12～14F, and the circumference diameters of the S-shaped pipe 4 and the subsidiary pipe 8 are 6～8F.

When in use, first insert the auxiliary tube 8 into the channel 11, the joint 1 communicates with the external negative pressure machine, the auxiliary tube 8 can be connected with the atmosphere to realize natural drainage, and can also be connected with negative pressure to achieve negative pressure drainage. At the time, both the upper branch 6 and the S-shaped tube 4 are placed inside the bile duct. During the operation, the umbrella-shaped soft wing 5 is folded and stuffed into the inside of the bile duct, and cooperates with the upper branch 6 as the first-level structure, thereby blocking the The bile flows out, and the umbrella-shaped soft wings 5 can gather when pulled outward; meanwhile, the S-shaped tube 4 is also located inside the bile duct, and the drainage hole 7 arranged on the curved inner side of the S-shaped tube 4 facilitates the drainage of digestive juice and bile, and can avoid negative During pressure suction, the wall of the bile duct is tightly attached to the drainage hole 7 to avoid affecting the drainage. This structure is the second-level structure; For the closure of the bile duct wound, since the middle part of the square mesh 3 and the shuttle-shaped blocking ring 10 have holes that are compatible with the drainage main pipe 2, the drainage main pipe 2 can pass through the inside of the bile duct, and the carboxymethyl cellulose net can be used With the characteristic of forming gel in contact with water, the inner layer of polyglycolic acid film is adhered and fixed on the wound of the bile duct wall during the operation, and the gap between it and the main drainage tube is closed, without manual suturing of the bile duct wall, thus It reduces the difficulty of the operation and the occurrence of postoperative complications. This structure is a tertiary structure; the end of the accessory tube 8 with the drainage hole 7 is placed in the operation area near the place where the drainage main tube 2 enters and exits the bile duct, and the drainage hole 7 is used to Suction the exudate in the operation area and the bile and other digestive juices overflowing the bile duct through the tertiary structure, so as to prevent the bile and other digestive juices from entering the body cavity. There are two tubes, thereby reducing the pain of the patient and reducing the chance of detachment; because there is a film on the outside of the subsidiary tube 8, it can ensure that the space between the subsidiary tube 8 and the channel 11 becomes a closed structure, so that the drainage main tube 2 is not connected inside and outside, and the inside and outside of the subsidiary tube 8 When pulling out, the elastic support ring 9 can prop up the soft film 13 of the elastic structure, so that the channel 11 is in a closed state; after a few months, a mature fistula will be formed around the drainage main pipe 2, at this time, the drainage main pipe 2 can be removed. Pull out, at this time the absorbable material has basically degraded and absorbed by itself.

To sum up, the postoperative suture-free drainage device is equipped with an elastic structure soft film 13, so that the auxiliary tube 8 can be inserted into the drainage main tube 2 for drainage. After the operation, only one drainage main tube 2 needs to be inserted on the patient, and it can Effectively avoid many problems caused by two intubation tubes, reduce the number of intubation wounds, reduce the pain of the patient, and reduce the chance of detachment. Since there is only one cannula on the patient, it can effectively shorten the length of the patient's life It also reduces the number of scars on the body after recovery. By setting the square mesh 3, the carboxymethyl cellulose mesh forms a gel when it meets water during the operation, which can adhere and fix the inner layer of polyglycolic acid membrane to the defect of the bile duct wall. , and close the gap between it and the main drainage tube, no sutures can be realized during the operation, the difficulty of the operation is reduced, and the occurrence of postoperative complications is reduced.
