Description

Technical Field

[0001] The utility model relates to the technical field of prostate tissue collection, in particular to a prostate tissue specimen collection device. Background Art

[0002] Benign prostatic hyperplasia (BPH) is a common disease in elderly men. In severe cases, it can cause urinary retention, and may also lead to secondary infections and bladder stones. Transurethral transurethral resection of the prostate (TURP) is the most commonly used minimally invasive surgical technique for BPH. This technique offers advantages such as minimal trauma, rapid recovery, and reduced hospital stays. However, different hospitals use different methods to collect prostate tissue removed during surgery. Currently, urology departments mostly use plastic buckets to collect irrigating fluid and prostate tissue specimens during prostate surgery. After the operation, the irrigating fluid and tissue in the buckets are separated. This is not only time-consuming and labor-intensive, but also easily causes surgical waste fluid to splash onto the ground, posing a safety hazard. This is especially true for patients with enlarged prostates, as surgery is long, and the amount of irrigating fluid used during the operation and the amount of tissue specimens removed after the operation are large, making separation difficult and even incomplete tissue collection. This can affect the pathological diagnosis and the postoperative specimen weighing.

DETAILED DESCRIPTION

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0023] Example: See Figure 1-5 A prostate tissue specimen collection device includes a bottle body with a channel structure inserted in the bottle body. The bottle body includes a hard bottle cap 1, a soft bottle body 2, and a hard bottle bottom 3. The hard bottle cap 1, the soft bottle body 2, and the hard bottle bottom 3 are an integrated structure. The channel structure is inserted in the center of the hard bottle cap 1.

[0024] In the specific implementation process, a liquid filling port 4 is opened on the upper wall of the hard bottle cap 1 and located on one side of the channel structure. A sealing component is provided at the liquid filling port 4. The soft bottle body 2 is provided at the lower end of the hard bottle cap 1, and the hard bottle bottom 3 is provided at the lower end of the soft bottle body 2.

[0025] In a specific implementation process, a first through hole is formed on the hard bottle bottom 3, a first filter 5 is installed on the first through hole, a first rotating column 6 is movably inserted into the lower wall of the hard bottle bottom 3, a rotating bottom 7 is installed at the lower end of the first rotating column 6, and the rotating bottom 7 is movably attached to the lower wall of the hard bottle bottom 3, a second through hole corresponding to the first through hole is formed on the hard bottle bottom 3, and a second filter 8 is installed on the second through hole;

[0026] In the specific implementation process, the channel structure includes a conduit 9, which is fixedly inserted in the center of the hard bottle cap 1. A drainage tube 10 is inserted at one end of the conduit 9 located inside the bottle body. The lower end of the drainage tube 10 is a closed structure. The drainage tube 10 is provided with a plurality of liquid holes 11. A connecting terminal 12 is installed at one end of the conduit 9 located inside the bottle body.

[0027] In a specific implementation, the closure assembly includes a second rotating column 13, which is movably inserted into the upper wall of the hard bottle cap 1 and is located on one side of the conduit 9. A closure cap 14 is mounted on the upper end of the second rotating column 13, and a sealing gasket 15 is mounted on the lower wall of the closure cap 14. The sealing gasket 15 is movably fitted on the upper wall of the hard bottle cap 1.

[0028] It should be noted that when collecting prostate tissue specimens, the positions of the first filter 5 and the second filter are staggered, and the first filter 5 is sealed by the non-second filter area of ​​the rotating bottom 7. The flushing liquid is added to the bottle body composed of the hard bottle cap 1, the soft bottle body 2 and the hard bottle bottom 3 through the liquid injection port 4, and the closing cover 14 and the sealing gasket 15 on the lower wall of the closing cover 14 are rotated with the second rotating column 13 as the center to block the liquid injection port 4, thereby achieving the sealing of the liquid injection port 4, and connecting the plasma mirror or electrosurgical resectoscope sheath instrument to the connecting end 12. Then the medical staff manually squeezes the soft bottle body 2 to generate negative pressure in the bottle body, and the flushing liquid enters the catheter 9 through the multiple liquid holes 11 opened on the drainage tube 10. The prostate tissue and the flushing fluid are mixed into a mixed liquid. The medical staff releases the negative pressure drainage ball body 3. Since the negative pressure drainage ball body 3 is in a squeezed state before, the soft bottle body 2 is released. Under the balance of air pressure, the mixed liquid in the bladder flows back into the bottle body. The mixed liquid enters the bottle body through multiple liquid holes 11. When the mixed liquid needs to be separated, the rotating bottom 7 is rotated to drive the first rotating column 6 to rotate until the second filter 8 is aligned with the first filter 5. The waste liquid is filtered by the first filter 5 and the second filter 8 and discharged from the outside of the bottle body, while the prostate tissue specimen remains inside the bottle body, which is convenient for collecting the prostate tissue specimen.

[0029] As a preferred embodiment, a ring groove is formed on the lower wall of the hard bottle bottom 3, a sealing ring 16 is installed on the inner wall of the ring groove, and a ring 17 is installed on the rotating bottom 7. The ring 17 is movably inserted on the sealing ring 16; when the rotating bottom 7 rotates, the rotating bottom 7 drives the ring 17 to rotate on the sealing ring 16, and the sealing ring 16 is used to seal the gap between the hard bottle bottom 3 and the sealing ring 16 to prevent liquid leakage;

[0030] As a preferred embodiment, further, an enlarged ring 18 is installed on the outer wall of the rotating bottom 7, and the enlarged ring 18 is movably fitted on the outer wall of the hard bottle bottom 3. The enlarged ring 18 increases the contact area between the medical staff's hands and the rotating bottom 7, making it easier to operate;

[0031] As a preferred embodiment, further, the outer wall of the soft bottle body 2 is provided with scale lines 19 for measuring the volume of prostate tissue.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
