Description

Subdural tumor remover

Technical Field

The utility model relates to a medical appliance, in particular to a subdural tumor remover, which is mainly applied to the fields of gynecologic and obstetric endoscopic surgery, etc.

Background

Nowadays, the incidence of tumors is increasing, and people pay attention to the tumors. However, many tumors are discovered and have metastasis, for example, the primary tumors from stomach, intestine, ovary and the like often have pelvic cavity colonization metastasis. The mode of cancer cell metastasis is that cancer cells can penetrate through peritoneal, pleural, pericardial or subarachnoid spaces to invade body cavities to generate cancer metastasis, and castellated metastasis foci are often seen at the peritoneal, visceral serosal surfaces, subdural and other positions in the operation.

At present, the operation is one of the important methods for treating the tumor, and the operation is performed by using instruments under an endoscope, so that the operation is widely applied to clinic due to the advantages of intuition, minimal invasion, short recovery time of a patient and the like, and the operation is paid attention by doctors. The implanted metastasis focus of the tumor mostly exists in the superficial parts of the peritoneum, the diaphragm and other positions, and can be simply removed by using an aspirator, thereby achieving the satisfactory tumor reduction and extinction operation. Endoscopic surgery also has some drawbacks. First, the distance from the umbilicus to the sub-diaphragm, if calculated, may be more than 30 cm at the most. The length of the conventional endoscope instrument is about 30 cm, so that some deep planting metastases are difficult to thoroughly clear, and the survival and prognosis of tumor patients are greatly influenced; secondly, the visual field is small under the endoscope, the operation space is limited, the implantation position of some focuses is too deep or is surrounded by other tissues, the conventional method is difficult to reach, and the chief physician often looks at the tumor.

Application No.: 201710372141.X discloses a detachable laparoscopic aspirator, which is shaped like a hollow tube and consists of an upper section, a middle section and a lower section, wherein the upper section is used for being connected with a conventional suction tube and a negative pressure device; the lower section is a main body of the suction apparatus and is used for extending into the body of a patient, and the middle section consists of two arc-shaped tubes and a connecting tube; the arc-shaped pipe has larger radian and is used for clamping and fixing the laparoscope operating device and can be completely matched with the operating device for wrapping the laparoscope. The suction apparatus and the operation device in the laparoscopic instrument are integrated, and can be mutually detached, assembled and matched randomly, so that the operation is more convenient, the operation efficiency is improved, the operation effect is ensured, and the aims of micro-wound, convenience and high efficiency are fulfilled; and the disposable use is more sanitary, and the possibility of secondary infection is reduced.

However, clinical practice shows that no endoscopic tumor removal instrument capable of compensating the defects is available.
