Tumor puncture sampling equipment for gynaecology and obstetrics

Abstract

The invention discloses a tumor puncture sampling equipment for gynaecology and obstetrics. The tumor puncture sampling equipment comprises a positioning cylinder, a positioning structure and a sampling cylinder; the positioning cylinder is cylindrical, an inserting cavity is formed in the positioning cylinder, a group of measuring cavities are horizontally formed in the top of the positioning cylinder, an inlet allowing the positioning structure to extend into is formed in one end of the positioning cylinder, A penetrating hole for the sampling needle to penetrate through is drilled in the other end of the positioning cylinder, a fastening structure matched with the fastening groove is arranged at the extending end, corresponding to the push rod, of the sampling cylinder, fixing holes matched with the fixing structure are formed in the two parallel side edges of the sampling cylinder, and a measuring block is fixed to the top of the end, close to the sampling needle, of the top of thesampling cylinder; and the measuring block is arranged in the positioning groove. The tumor puncture sampling equipment for the obstetrics and gynecology department is reasonable in design, can perform auxiliary positioning before sampling, can prevent a sample from retracting due to pressure after sampling, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of tumor puncture sampling, and in particular relates to a device for puncture sampling of obstetrics and gynecology tumors. Background technique [0002] Puncture sampling is the main method for obstetrics and gynecology tumor acquisition and pathological diagnosis. Tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. The prognosis has an important impact. With the continuous improvement of inspection methods and methods, the correct rate of diagnosis is gradually improved, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. Correct diagnosis requires clinical, imaging and Three combinations of pathology, in which pathological diagnosis plays a key role in the selection of treatment options, and puncture sampling is the main wa...

[0002] Puncture sampling is the main method for obstetrics and gynecology tumor acquisition and pathological diagnosis. Tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. The prognosis has an important impact. With the continuous improvement of inspection methods and methods, the correct rate of diagnosis is gradually improved, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. Correct diagnosis requires clinical, imaging and Three combinations of pathology, in which pathological diagnosis plays a key role in the selection of treatment options, and puncture sampling is the main way to obtain pathological diagnosis

[0003] Existing tumor puncture sampling equipment cannot perform good positioning during puncture. After puncture and sampling, the negative pressure in the body is likely to cause the sample to be sucked back when the sampling needle is withdrawn.
