Subperitoneal administration device

Abstract

The invention relates to a subperitoneal administration device. The subperitoneal administration device comprises a handle used for operation, an administration needle used for administration and an operation body connected with the handle, wherein an administration structure used for administration is arranged in the operation body, the administration needle is connected with the operation body and is a hollow needle, and the front end of the administration structure extends into the administration needle; the handle is connected with the administration structure, and the handle is pressed to control the administration structure to move in the administration needle; and the administration structure moves forwards in the administration needle to push a medicine in the administration needle to a treatment position, and the front end of the administration structure extends into the administration needle, so that the problem that medicine particles are blown back under the positive pressure of peritoneum can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a subperitoneal drug delivery device. Background technique [0002] At present, the treatment methods for peritoneal tumors include surgical resection and intraperitoneal perfusion hyperthermia or chemotherapy, but these two treatment methods belong to intraperitoneal administration; and intraperitoneal administration is to put the chemotherapy drugs used into the patient's peritoneal disease site, so that the patient The effective drug concentration at the hair point is higher, so as to obtain better clinical treatment effect. For subperitoneal administration, there is currently no experience and technology related to subperitoneal administration at home and abroad. [0003] At present, if you want to treat peritoneal tumors clinically by subperitoneal administration, you can incise part of the peritoneum to inject drugs in the laparotomy state, and then sut...

AI Technical Summary

Problems solved by technology

[0003] At present, if you want to treat peritoneal tumors clinically by subperitoneal administration, you can incise part of the peritoneum to inject drugs in the laparotomy state, and then suture the peritoneum; but there is no relevant experience in laparoscopy: if you use existing instruments Intraperitoneal administration has the following risks: 1. During the laparoscopic operation, the peritoneum needs to be lifted, and then the drug is put into the subperitoneum, which requires a high level of experience for the operating physician; 2. There will be positive pressure gas in the peritoneum, which is easy to Blow off or blow out the administered medicine, causing the medicine to fail to enter the exact position; 3. When performing subperitoneal drug administration, there is a lack of special equipment, and the operation process is cumbersome, time-consuming and labor-intensive, and consumes the energy of the physician
