Visual peritoneal biopsy device through abdominal cavity pipe

Technical Field

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

Background

Biopsy is a short term biopsy, which is performed by taking pathological tissue from a patient's body by means of local cutting, clamping, puncturing, scraping, etc. Biopsy is the most commonly used method for diagnosing diseases at present, and several points need to be paid attention to improving the accuracy of biopsy pathology: 1. the biopsy site is selected from normal tissues at lesion sites, at the junctions of the lesions and surrounding normal tissues and between the lesions; 2. the biopsy needs to avoid the necrotic tissue area; 3. biopsy tissue is sufficient for pathological examination and is representative; 4. tissue of sufficient depth was taken and the relationship between tumor and interstitium was analyzed correctly.

Tumor resistance is an insurmountable problem in current malignant tumor treatment. As treatment time is prolonged, resistance of cancer cells increases, ultimately resulting in treatment failure. The biological activity changes almost all the time the tumor progresses and the drug resistance are changed, and the treatment method is also required to be continuously adjusted according to the biological activity. Multiple biopsies are necessary during diagnosis of tumor patients.

Conventional peritoneal biopsies typically require general anesthesia, laparoscopic probing or direct laparotomy, which have the disadvantages of anesthesia accidents, large lesions, and high costs. And the operation room is occupied, the cooperation of a plurality of persons is completed, and medical resources are occupied.

In addition, the placement of the peritoneal drainage tube can assist in repeated peritoneal irrigation and peritoneal thermal infusion chemotherapy, and general anesthesia and laparoscopic lower tube placement are usually required for the placement of the peritoneal drainage tube of a patient with peritoneal tumor without ascites, so that the defects of anesthesia accidents, large damage and high cost exist; the abdominal cavity catheterization can be performed under the guidance of CT and B ultrasonic, but because the abdominal wall and the intestinal cavity have no obvious gap, the needle insertion depth is difficult to grasp, and the risk of intestinal fistula caused by mistaken intestinal canal penetration exists.

Chinese patent application: CN102512211B discloses a multi-coating biopsy puncture needle capable of sampling for multiple times, which comprises a biopsy puncture needle core and a needle cylinder, wherein a sampling groove is arranged on the biopsy puncture needle core, a tissue pushing block is arranged in the end head of the needle cylinder, a transverse line perpendicular to the long axis of the needle cylinder is arranged on one side surface of the pushing block, which is opposite to the sampling groove, and two sides of the pushing block are designed into inclined planes which have the same included angle with the conical inclined plane of the biopsy puncture needle core; the length of a sampling groove of the biopsy puncture needle core is increased to 2 times of the standard length, and the surface of the sampling groove is covered with a polytetrafluoroethylene coating; the total length of the biopsy puncture needle is more than or equal to 90mm, the inner diameter of the needle cylinder is more than or equal to 0.64mm, the outer diameter of the needle cylinder is more than or equal to 0.91mm, the cone length of the needle tip part is 5mm, the included angle of the conical inclined surface is 15-20 degrees, the included angle of the cutting surface is 20-25 degrees, and the surfaces of the tip ends of the needle cylinder and the biopsy puncture needle core are covered with polytetrafluoroethylene coatings. The device can cut living tissues continuously, and the cut biopsy tissue strip is complete; the operation time is greatly shortened, the pain of a patient is reduced to the greatest extent, the biopsy is taken as a blind puncture, repeated puncture is needed for a plurality of times, the pain and the risk of the patient are increased, the visual puncture process is not realized, the risk of puncture failure and even damage to surrounding tissues and organs exists, and bleeding and infection complications can be caused.

Therefore, in view of the above, there is a need for a visual peritoneal biopsy device through a peritoneal catheter that can realize visualization of surgical procedures such as peritoneal puncture and peritoneal biopsy, greatly improve the safety and success rate of surgery, reduce the workload of operators, and reduce the pain of patients, but no report has been made at present on the visual peritoneal biopsy device through a peritoneal catheter.
