Puncture stent for prostate biopsy

Abstract

The invention belongs to the field of medical instruments, and provides a puncture support for prostate biopsy, which comprises a first support, a second support movably connected in the first support, a needle groove plate detachably connected to the front end of the second support, and a semicircular clamping frame connected to the bottom of the first support and used for connecting an ultrasonic probe. According to the puncture support and the needle groove plate, the puncture support and the needle groove plate can be attached to the skin of a patient in a self-adaptive mode, through the stepped design, a user can memorize the puncture support conveniently, operation is easy, stability is high, the user and the patient cannot be interfered, and puncture safety is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a puncture stent for prostate biopsy. Background technique [0002] Located deep in a man's pelvis, the prostate is a chestnut-like gland that produces fluid that nourishes and transports sperm. As men age, the risk of prostate cancer also increases. As my country gradually enters an aging society and the country's popularization of tumor screening, prostate cancer has occupied the first morbidity and mortality rate among male urological malignant tumors in my country, seriously threatening the health of patients. Therefore, for middle-aged and elderly men, if the outpatient clinic finds abnormal prostate-specific antigen (PSA) or digital rectal examination, urologists will recommend prostate biopsy. [0003] Common biopsy methods are: [0004] 1. Transrectal biopsy, the needle is passed through the rectal wall under ultrasound guidance for prostate biopsy. [0005] 2. For ...

AI Technical Summary

Problems solved by technology

[0007] 1. When different positions need to be punctured, the puncture holes on the needle slot plate are evenly arranged, and the recognition degree of each puncture hole is not high, it is difficult to remember the last puncture position, and repeated puncture may occur, thereby increasing the risk of puncture

[0008] 2. Due to the different lengths of the ultrasonic probes, the needle slot plate needs to be adjusted back and forth to fit the patient’s skin. Usually, the doctor needs to make repeated adjustments according to the actual situation, which is cumbersome

[0009] 3. The clamping frame of the ultrasonic probe is usually equipped with a clamp or other locking mechanism, and the overall volume is large, which will interfere with the doctor's hand-holding or touch the patient's skin
