Problems solved by technology

The incidence of fever, rectal bleeding, and even sepsis after transrectal puncture system is relatively high, and the inflammation and adhesion in the early prostate-rectal space after puncture are serious, which affects the operation and is prone to surgical complications
[0005] The transperineal puncture system has the following disadvantages: severe pain, low puncture pass rate, puncture points from the apex of the prostate into the apex of the prostate, inflammation and edema are obvious, which is not good for protecting important tissues such as the vascular nerve bundle and sphincter muscle of the apex of the prostate during operation , thus affecting the recovery of urinary continence and erectile function after radical surgery
However, transurethral and transrectal and transperineal structures are completely different, and there is no available transurethral prostate biopsy system, so a visual transurethral prostate biopsy system is urgently needed

Embodiment 1

[0053] Embodiment 1, taking the biopsy of the anterior lobe of the prostate as an example: the anterior lobe of the prostate is close to the perineum, and it is not easy to puncture the lesion at this site using the traditional transrectal biopsy method. During use, outer sleeve 7 is inserted from urethra 32 (as Figure 9 shown), then, add the ureteroscope 2 and the puncture needle 3, swing the support bracket 8 upwards, and align the hammer 11 with the firing position of the puncture needle 3 (that is, the needle seat 302 of the puncture needle); the ureteroscope 2 is in the Under the guidance of the camera 4, reach the position of the prostate 33, adjust the angle of the ureteroscope 2, aim at the anterior lobe of the prostate, use the endoscopic ultrasound probe to touch the anterior lobe of the prostate, observe the lesion tissue inside the prostate, align the lesion tissue, and pull the trigger 12 , the trigger 12 drives the hammer 11 to swing forward through the V-shaped...

Embodiment 2

[0054] Example 2, taking the needle biopsy of lesions at the base of the prostate (near the bladder) as an example: the base of the prostate near the bladder 34 is a site that is not easy to sample for a prostate needle biopsy via the perineal method. During use, outer sleeve 7 is inserted from urethra 32 (as Figure 10 shown), then add the ureteroscope 2 and the puncture needle 3, swing the support bracket 8 up to the position, and align the hammer 11 with the firing position of the puncture needle 3 (that is, the needle seat of the puncture needle); Under the guidance of 4, reach the position of the prostate 33, adjust the angle of the ureteroscope 2, aim at the base of the prostate, use the endoscopic ultrasound probe 5 to touch the base of the prostate, observe the lesion tissue inside the prostate, align the lesion tissue, and pull the trigger 12, The trigger 12 drives the hammer 11 to swing forward through the V-shaped swing block 10, and then fires the puncture needle 3...

Abstract

The invention relates to a multi-visual transurethral prostate needle biopsy system and a use method thereof. The multi-visual transurethral prostate needle biopsy system comprises a base, a ureteroscope and a puncture needle, a camera and an ultrasonic probe are arranged at the front end of the ureteroscope, a puncture sleeve is arranged at the bottom of the outer side face of the ureteroscope in parallel, and a needle body of the puncture needle slidably penetrates through the puncture sleeve; and the base comprises an outer sleeve used for being inserted into the urethra, the outer sleeve slidably sleeves the outer side of the ureteroscope and the puncture sleeve, and a driving mechanism used for driving the puncture needle to move forwards along the puncture sleeve is arranged at the rear end of the outer sleeve. Precise prostate needle biopsy of a transurethral sterile part is achieved, infection is effectively avoided, bleeding can be stopped under direct vision after puncture, postoperative bleeding can be reduced, the puncture qualification rate is increased, and pain of a patient is relieved; and cleaning is achieved through a flushing assembly and a waste liquid discharging assembly, bleeding inflammation adhesion around the prostate is reduced, cleaning of an operating table is achieved, and smooth proceeding of subsequent surgical operation is facilitated.

Description

Technical field: [0001] The invention relates to a multiple visualization transurethral prostate puncture biopsy system and its application method. Background technique: [0002] Prostate cancer is the malignant tumor with the highest incidence rate among men in the world. With the acceleration of the aging society, the number of new cases worldwide continues to increase every year. In 2020, there will be 110,000 new cases of prostate cancer in China, and 50,000 deaths from prostate cancer, ranking 13th in the number of cancer deaths. In 2020, the number of new cases of prostate cancer worldwide will be 1.41 million, accounting for 7.3% of the total number of new cancer cases, and the number of prostate cancer deaths will be 380,000, accounting for 3.8% of the total number of cancer deaths. Prostate biopsy is the gold standard for diagnosing and excluding prostate cancer. More than millions of prostate biopsies are performed every year around the world. It is a necessary in...
