Description

Tumor fixer under laparoscope

Technical Field

The utility model relates to the technical field of medical equipment, especially relate to a tumour fixer under peritoneoscope.

Background

Renal carcinoma is a common tumor of urinary system, accounting for 3% of adult malignant tumors, and the incidence rate gradually rises in recent years by 2-3% compared with 10 years ago. According to the relevant literature, about 209000 newly added cases of kidney cancer and 102000 death cases of kidney cancer are reported each year worldwide. The malignancy of kidney cancer is high, 25-30% of patients are in advanced stage at the time of diagnosis, and 30-40% of patients with renal cancer without metastasis have distant metastasis after surgical treatment, so that the diagnosis and treatment of renal cancer are extremely challenging. The diagnosis and treatment of kidney cancer is subjected to long-term exploration and evolution, the staging and radical operation standards of kidney cancer are proposed by Robson in 1969, the kidney cancer starts to enter the standardized treatment in the 70 s of the 20 th century, the TNM staging is proposed by the International anticancer Union (UICC) in the 80 s, the kidney cancer is gradually applied to the clinic, the TNM staging and tumor staging standards are revised by the United states cancer Joint Committee (AJCC) at the end of the 90 s, and other surgical formulas of the kidney cancer are gradually popularized in the clinic. The partial nephrectomy is gradually a recommended formula for treating the kidney cancer in the stage T1 in recent years, the minimally invasive requirement of a patient on treatment is higher and higher along with the improvement of living standard and medical technology of people, the laparoscope is gradually a mainstream formula of clinical surgery, and a single-shot convex tumor with the diameter of less than 4cm is an indication of the partial nephrectomy selected by most doctors. Many studies show that there is no obvious difference in prognosis in laparoscopic partial resection compared with open renal partial resection, but the laparoscopic partial resection has the advantages of reserved renal function, less bleeding during surgery, short surgery time, fast postoperative recovery, etc., and with the continuous improvement of surgical instruments and skills of surgeons, the laparoscopic partial resection of renal is also gradually applied to some complex situations such as tumors with larger volume or renal hilum tumors, etc.

The existing laparoscope device is advanced, high in definition and skilled in operation, a 3D laparoscope technology is developed, two-dimensional imaging of a common laparoscope is improved, and operation time is shortened to a certain extent. Because the laparoscope mainly adopts the intracavity operation and the content is embodied in the external display, the operator holds the endoscope instrument to operate outside the body of the patient, the difficulty is high, and the operator is required to fully master the anatomical structure and the focus property. Under the action of gravity, perirenal tissues which are wandering away during operation often naturally fall down to influence the operation visual field and the operation of an operator, and if the operator directly lifts the kidney or the tumor by an instrument, the possibility that the kidney breaks and bleeds to influence the definition of the operation visual field or cause the tumor to break to cause the implantation metastasis is generated.

At present, the operator usually selects a single hand-held instrument to lift the perirenal tissue to expose the visual field, and carries out the dissociation and excision operation with the other hand, which is very inconvenient. Meanwhile, the pathological incisal margin positivity after operation is also a problem which cannot be ignored in the current clinic, and although the occurrence of incisal margin positivity can be avoided by means of abundant operation experience, the problem cannot be ignored. Many years of operation experience proves that the clinical significance of reducing the positive pathological margin after operation is far greater than the problem of exact incision after tumor resection. How to design a device can effectively solve the problems is worth further thinking.
