Description

Medical negative pressure drainage device for reducing tumor cell diffusion

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to a medical negative pressure drainage device for reducing tumor cell diffusion.

Background

Current tumor surgery reduces the process of tumor spread

1. Intraoperative exploration and surgical procedure sequence:

(1) intra-operative exploration follows the principle from far to near: the detection of tumors in the abdominal cavity or the thoracic cavity is carried out by starting from an organ tissue far from the organ in which the tumor is located and finally detecting the organ in which the tumor is located, preferably a lesion, without direct contact by hand. Laparoscopic exploration may now better follow the principles of tumor-free exploration. The surgical procedure should be dissected from the periphery of the tumor towards the center. If the tumor breaks through serosa, the biological glue is preferably used for sealing the tumor wound surface, so that the tumor spreading and falling chance in the operation is reduced.

(2) Blood vessels surrounding the tumor were treated first and the tissue surrounding the tumor was isolated: blood metastasis of tumor cells, mainly cancer cells enter veins and circulate with the blood. The operations of traction, extrusion or separation in the operation can cause the tumor cells to enter the blood circulation, which leads to the blood circulation spreading of the tumor cells.

2. Non-contact isolation technique: no matter the operation is an open abdomen operation or a laparoscopic operation, the direct contact of the tumor by hands or instruments is avoided as much as possible, and the tumor spreading chance is reduced; the gauze pad is used for protecting the edge of an incision and normal visceral organs around the tumor in the operation process; when the tumor is cracked in the operation, the tumor needs to be sucked and removed, the tumor is tightly covered or wrapped by a gauze pad, and gloves and surgical instruments are replaced.

3. Following the radical principle of monoblock excision: regardless of the size of the tumor, to avoid the removal of the tumor in blocks, it is preferable to remove the tumor as a whole, typically not less than 3cm from the tumor margin. The excision of sarcomas requires complete excision of the affected muscle group from the beginning of the muscle to the point of muscle attachment. If the tumor affects peripheral organs but there is no distant metastasis, the affected organs or tissues are also excised in one piece.

4. The method is characterized by comprising the following steps of (1) multi-purpose sharp separation and less-purpose blunt separation: sharp separation is the direct dissection of tissue with a cutting tool such as a scalpel, scissors, electrotome, or ultrasonic blade; blunt dissection is carried out by hand or by instruments. The blunt separation cleaning is poor in thoroughness, and due to the fact that tumor scattering is easily caused by extrusion, the blunt separation is avoided or used less, and sharp separation is used as much as possible. In addition, the electric knife is adopted for cutting during the operation, so that bleeding can be reduced, small blood vessels and lymphatic vessels can be sealed, and the high-frequency electric knife has the function of killing cancer cells, so that blood channel scattering and local planting can be reduced.

Tumors vary in type and severity of the consequences of rupture. If the huge interstitial tumor of the abdominal cavity is ruptured, recurrence is almost inevitable, even if the interstitial tumor is very small, and once the massive interstitial tumor is ruptured in the operation, the massive interstitial tumor is directly divided into a very high-risk group.

There are also appendiceal or ovarian mucinous adenocarcinomas, most of which form cystic masses, enveloped. The patient should touch the abdomen and the pelvis carefully and gently during the operation, once the patient breaks, mucus spreads in the abdomen and the pelvis and is difficult to clean, and even a large amount of physiological saline is used for washing, the mucus is difficult to thoroughly clean.

In a word, no matter which kind of tumor, the medicine source rupture in the operation should be avoided as much as possible, which leads to the tumor dissemination. In the whole operation process, all the personnel involved in the operation strictly follow the principle of tumor-free and sterility, and the iatrogenic tumor dissemination is reduced or avoided to the maximum extent. The key point in tumor surgery is how to establish a continuous negative pressure suction operation space, thereby greatly reducing the tumor dissemination caused by iatrogenic rupture.

Therefore, there is a need to provide a new medical negative pressure drainage device for reducing tumor cell diffusion to overcome the above problems.
