Embodiment 1

[0030] see Figure 1 to Figure 5 , the present invention provides a prostate puncture device, the base is provided with a chute, and the upper side of the base slides to connect the prostate support mechanism 1 and the puncture needle 2 sequentially through the chute, the prostate support mechanism 1 is located in front of the needle tip of the puncture needle 2, the prostate support mechanism 1 and the puncture needle 2 are respectively slidably connected to the chute through a support rod 3, and the bottom end of the support rod 31 is fixedly provided with a slider corresponding to the chute, and the top end is connected with the bottom ball joint of the fixed ring 31; the two support rods 3 The fixing ring 31 is respectively fixedly sleeved with the prostate supporting mechanism 1 and the puncture needle 2;

[0031] The prostate supporting mechanism 1 includes an outer cylinder 101, which is a hollow cylinder with openings at both ends. The outer cylinder 1 is sleeved with ...

Embodiment 2

[0042] On the basis of Embodiment 1, different from Embodiment 1, the rod body of the sleeve rod 114 is sleeved with a limit plate 116, and the limit plate 116 includes an annular ring sleeved outside the sleeve rod 114, and is arranged on the ring ring. The baffle plate in the radial direction; the locking bolt is arranged on the annular ring, and the distance from the outer side of the baffle plate to the circular ring is greater than or equal to the radius of the outer cylinder 101 .

[0043] The rear end of the outer cylinder 101 is provided with a rear boss, and threaded holes are provided on the baffles of the rear boss and the limiting plate 116, and the rear boss and the limiting plate 116 are locked by bolts. The function of the limiting plate 116 is to limit the length of the inner component 110 extending into the outer cylinder 101. This purpose is achieved by limiting the inner rod 111, so as to prevent the inner component from excessively extending into the human b...

Embodiment 3

[0045] The device can also be based on the existing technology, with the help of the existing technology, to add a visual component at the end of the support component 112, which is more convenient for medical personnel to use.

Abstract

The invention discloses a prostatic puncture device, and relates to the field of medical equipment. According to the technical scheme, the prostatic puncture device comprises a base, wherein the baseis provided with a sliding groove, the upper side of the base is slidably connected with a prostatic supporting mechanism and a puncture needle through the sliding groove in sequence, the prostatic supporting mechanism is located at the front side of the point of the puncture needle, and the prostatic supporting mechanism and the puncture needle are slidably connected with the sliding groove through supporting rods respectively; the prostatic supporting mechanism comprises an outer cylinder, the outer cylinder is a hollow cylinder of which the two ends are provided with openings, and the outercylinder is internally in sleeved connection with an internal assembly; the rear side end of a supporting assembly is hinged with the front side end of an inner rod. The prostatic puncture device hasthe advantages that the use is simple, no complex operation step exists, the smoother outer cylinder of the device enters the anus of a patient more easily, and the supporting assembly of the devicecan be unfolded after the device enters the human body, thereby reducing the pain of the patient, and ensuring the enough supporting area and supporting strength for the prostate.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a prostate puncture device. Background technique [0002] Prostate cancer is one of the most common cancers in elderly men and has seriously endangered human health. Recent statistics have found that the incidence of prostate cancer in the world ranks sixth among the most common malignant tumors (new cases), and ranks third among common male malignant tumors ; With the improvement of the average life expectancy in our country, the change of life structure and the increase of people's attention to prostate cancer, the incidence and detection rate of prostate cancer in my country have also increased significantly; Needle biopsy is the ultimate standard and the best method for diagnosis of prostate cancer; there are two ways to implement prostate needle biopsy, one way is through the perineum, and the other way is through the rectum. [0003] Among them, the advantages of the transpe...
