Description

Specimen collection bag Technical Field The application relates to the technical field of specimen bags, in particular to a specimen collection bag. Background Pelvic lymph node cleaning surgery is a procedure that uses open or laparoscopic surgical techniques to resect the entire body of fibrous adipose and lymphoid tissue anterior, posterior, and between the vessels of the external iliac artery, vein, ranging down to the inguinal canal and posterior to the area posterior to the obturator nerve. It is commonly used for radical cystectomy and radical prostatectomy. Tissue and other resections cut by surgery need to be soaked in a fixative solution and kept sealed for post-operative detection of the resections. In the related art, before an operation, a fixing solution needs to be injected into a specimen bag to provide a fixing solution environment in the specimen bag, and a cut-out generated during the operation is placed into the specimen bag to be soaked and stored in the fixing solution. However, before the operation, the fixing liquid needs to be configured, the fixing liquid needs to be injected into the specimen bag, so that preparation for preserving the specimen before the operation is calculated, the operation of configuring the fixing liquid and injecting the fixing liquid into the specimen bag is complicated, and the risk of dumping exists in the process of transferring the specimen bag to an operating room. Disclosure of utility model The embodiment of the application provides a specimen collection bag, which aims to solve the technical problems that the process of preparing a fixing liquid before an operation and injecting the fixing liquid into the specimen bag is complicated in the related art, and the risk of pouring the fixing liquid exists in the process of transferring the specimen bag to an operating room.
