Description

Sampler for medical oncology

Technical Field

The utility model relates to the technical field of medical equipment, specifically be a sampler for medical oncology.

Background

As is known, clinical sampling of body surface tumor biopsy for a patient can be successfully realized through a surgical incision, but the surgical incision can bring great pain to the patient, so that a syringe is generally adopted for sampling at present, and tumor tissues are sucked by virtue of negative pressure generated by the syringe. However, tumor sampling at some parts of the body cannot be achieved through surgical incisions, such as: the bladder, although capable of sucking tumor tissue by a syringe, cannot enter the bladder through the urethra, and still can cause great pain to patients because the bladder must pierce the cortex to suck the tumor tissue. Meanwhile, during sampling, the insertion depth of the injector can be judged only according to experience, so that the working difficulty of medical staff is increased; therefore, the existing use requirements are not satisfied.
