Safe multifunctional percutaneous puncture device for abdominal cavity diagnosis and treatment

Abstract

The invention relates to a safe multifunctional percutaneous puncture device for abdominal cavity diagnosis and treatment. The safe multifunctional percutaneous puncture device for abdominal cavity diagnosis and treatment comprises a hard sleeve with outer plastics, wherein an inner threaded connector is arranged at a rear end of the hard sleeve with outer plastics, the safe multifunctional percutaneous puncture device for abdominal cavity diagnosis and treatment further comprises a puncture needle and a biopsy probe which are used in cooperation with the hard sleeve with outer plastics, a puncture needle outer threaded connector used in cooperation with the inner threaded connector is arranged at a rear end of the puncture needle, a biopsy probe outer threaded connector used in cooperation with the inner threaded connector is arranged at a rear end of the biopsy probe, a hollow groove is formed in the biopsy probe, and a screw is arranged in the hollow groove. By means of the safe multifunctional percutaneous puncture device for abdominal cavity diagnosis and treatment, diagnosis and treatment of an abdominal cavity tumor are conducted through a minimally-invasive percutaneous puncture technology; a back waist approach or an anterior belly approach is arbitrarily chosen for puncture according to the position of the tumor; damage to adjacent organs and tissue of a spinal cord,kidneys, an intestinal canal and the like in the diagnosis and treatment processes of the abdominal cavity tumor is avoided; whether a biopsy needle or biopsy forceps are chosen for sampling depends on the size of the tumor; functions of biopsies and medicine injection are integrated; and needle tract implantation of the tumor can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a safe multifunctional percutaneous abdominal cavity diagnosis and treatment device. Background technique [0002] Tissue biopsy is of great value in tumor diagnosis and treatment. Clinically, there are the following problems and defects in conventional biopsy needles for intra-abdominal deep tumor (retroperitoneal) biopsy and drug injection: 1. Because of the deep tissue, the needle can only be inserted from the posterior waist approach , due to the anatomical structure on the puncture path, there is a risk of spinal cord and kidney damage; 2. If the tumor is small and wrapped around the abdominal aorta and inferior vena cava, there is a risk of damage to large blood vessels, making biopsy impossible and only Obtain tumor tissue by laparotomy or laparoscopic surgery; 3. If the tumor is in front of the large blood vessels, only a very thin needle can be used to enter fr...

[0002] Tissue biopsy is of great value in tumor diagnosis and treatment. Clinically, there are the following problems and defects in conventional biopsy needles for intra-abdominal deep tumor (retroperitoneal) biopsy and drug injection: 1. Because of the deep tissue, the needle can only be inserted from the posterior waist approach , due to the anatomical structure on the puncture path, there is a risk of spinal cord and kidney damage; 2. If the tumor is small and wrapped around the abdominal aorta and inferior vena cava, there is a risk of damage to large blood vessels, making biopsy impossible and only Obtain tumor tissue by laparotomy or laparoscopic surgery; 3. If the tumor is in front of the large blood vessels, only a very thin needle can be used to enter from the anterior abdomen, or the path can be seen under the ultrasound gastroscope with a fine needle. Because the abdominal cavity is full of intestines, they will pass through and damage the intestines, and the consequences are more serious; 4. Very thin needles cannot inject medicine for local treatment; 5. There is a three-thousandth risk of needle tract planting
