Description

Peritoneal cancer exploration device through peritoneal catheter

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a peritoneal cancer exploration device through a peritoneal catheter.

Background

Peritoneal metastasis is one of the leading causes of death of patients with advanced gastric cancer, colorectal cancer, ovarian cancer, appendiceal cancer, small intestine cancer, gallbladder bile duct cancer and the like, and is related to factors such as the external serosal shedding of primary tumor penetrating tumor tissue, the shedding of tumor cells in operation to the peritoneal cavity growth and the like. Taking gastric cancer as an example, 20% of gastric cancer patients are diagnosed with peritoneal metastasis before or during surgery, and 50% of patients with stage T3 and T4 undergo radical surgery. The incidence of appendiceal cancer and ovarian cancer complicated with peritoneal metastasis is higher. Peritoneal metastasis is a difficult diagnosis and treatment for various malignant tumors.

There are various imaging techniques for peritoneal cancer imaging diagnosis, such as CT, MRI, ultrasound, PET-CT, PET-MRI, etc. CT has heretofore been the imaging of choice for peritoneal cancer. However, due to the limitations of these imaging examinations, it is difficult to adequately assess the condition of peritoneal metastases, especially some multiple micrometastases. However, currently, the method of laparoscopic exploration is mostly used for PCI index (Peritoneal cancer index, PCI) evaluation, which has guiding effect on the treatment and prognosis of peritoneal cancer. The PCI score divided the peritoneal cavity into 9 abdominal pelvic regions (region 0: midabdominal region; region 1: upper right abdomen; region 2: upper abdomen; region 3: upper left abdomen; region 4: lateral colon groove; region 5: left iliac fossa; region 6: pelvic cavity; region 7: right iliac fossa; region 8: lateral right colonic groove) and 4 intestinal regions (region 9: upper jejunum; region 10: lower jejunum; region 11: upper ileum; region 12: lower ileum). Each zone ranks the range: stage 1: the diameter of the planting stove is less than 0.5cm;2 stages: the diameter of the planting stove is between 0.5 and 5cm; 3 stages: the diameter of the planting range is more than 5cm or the focus is fused. The 0-8 region includes, in addition to the peritoneum, cancerous nodules on the corresponding anatomy in that region. The sum of these 13 region scores is the PCI score, the lowest 0 score, and the highest 39 score.

At present, the PCI index is usually carried out by a general anesthesia lower laparoscope exploration or laparotomy exploration method, has the defects of great damage (the risks of the combined bleeding and intestinal perforation of important organs of the abdominal cavity such as liver, spleen, kidney and abdominal wall blood vessels, and the damage of the organs, and also correspondingly has the problem of damage caused by multi-angle perforation of the navel), and has high cost and occupies medical resources.

Chinese patent application: CN2539485Y discloses a processor for probing abdominal cavity, which comprises a probe, a catheter, a handle and the like, wherein an electric wire is arranged in the hollow catheter, a convex light source is arranged on the outer wall of the front end of the catheter, the light source is connected with the electric wire arranged in the catheter, and the electric wire is connected with a power switch arranged on the handle at the tail end of the catheter. The device can be used for physiological and pathological examination, can assist in abdominal surgery, and has the effects of examination and treatment. However, the whole structure is too simple, the functions are less, the device cannot be used together with the Trocar puncture outfit, the device still needs to be opened separately for matching with the Trocar puncture outfit, and the operation is inconvenient in many cases.

Therefore, in view of the above, there is a need for a device for probing peritoneal cancer via a peritoneal catheter that is easy to operate, capable of performing probing based on the abdominal cavity puncture, reducing unnecessary perforation operations, and helping to quickly find the tumor site, and realizing probing of each region one by one and measurement of the tumor size.
