Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a percutaneous nephroscope sheath with adjustable negative pressure suction side hole height. Background Technology

[0002] Kidney stones are solid, lumpy objects that form in the ducts or cavities of hollow organs (such as the kidneys, ureters, gallbladder, or bladder) in the human or animal body. Kidney stones specifically refer to stones that occur in the renal calyces, renal pelvis, and the junction of the renal pelvis and ureter. Most are located within the renal pelvis and calyces; stones in the renal parenchyma are rare. The kidneys are the primary site of urinary tract stone formation. Stones from any other part of the body can originate in the kidneys. Ureteral stones almost always originate from the kidneys, and kidney stones are more likely than stones from any other location to directly damage the kidneys, causing luminal obstruction, affecting fluid excretion from the affected organ, and resulting in symptoms such as pain, bleeding, or secondary infection. Percutaneous nephrolithotomy (PCNL) is a common treatment method, generally using a PCNL sheath or an ultra-micro PCNL sheath. However, the negative pressure side port of the PCNL sheath cannot be adjusted, which hinders the removal of large stone particles during stone fragmentation and expulsion in PCNL surgery, sometimes requiring repeated stone retrieval with forceps, resulting in slow stone removal. Therefore, there is an urgent need for a PCNL sheath with adjustable negative pressure suction side port height. Urinary tract stones are one of the most common diseases in urology, which can lead to serious complications such as hydronephrosis, infection, and kidney damage. Some patients with severe conditions require minimally invasive surgical treatment. For complex upper urinary tract stones (kidney and / or ureteral stones), percutaneous nephrolithotomy remains the preferred treatment.

[0003] Percutaneous nephrolithotomy (PCNL) requires the use of a percutaneous nephrolithotomy sheath. Currently, commonly used PCNL sheaths are mainly divided into two categories: conventional PCNL sheaths and negative pressure PCNL sheaths with a negative pressure suction side port. However, both types of PCNL sheaths have certain limitations and cannot fully meet clinical needs. Therefore, we have designed a PCNL sheath with adjustable side port height, capable of using different surgical modes (negative pressure or low pressure mode) to meet different clinical application scenarios and improve surgical efficiency and safety. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a percutaneous nephrolithotomy sheath with adjustable negative pressure suction side hole height. The buckle is locked at the side hole, and the position of the buckle is adjusted up and down to adjust the height of the negative pressure side hole, that is, to adjust the length of the stone fragment removal path and to achieve the sealing effect of the sheath, thereby enhancing the negative pressure suction efficiency. When negative pressure is not needed, the height of the side hole can be adjusted by adjusting the sealing strip.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A percutaneous nephrolithotomy sheath with adjustable negative pressure suction side port height, comprising:

[0011] As a preferred embodiment of the percutaneous nephrolithotomy sheath with adjustable negative pressure suction side hole height according to the present invention, the adjustment component includes a buckle that is snapped onto the outside of the sheath tube, the buckle being disposed on the side corresponding to the side hole, and the negative pressure side hole being connected to the outside of the buckle.

[0012] As a preferred embodiment of the percutaneous nephroscope sheath with adjustable negative pressure suction side hole height described in this utility model, wherein: a sealing strip is connected to the bottom of the buckle, and the sealing strip is configured to seal correspondingly with the side hole.

[0013] As a preferred embodiment of the percutaneous nephroscope sheath with adjustable negative pressure suction side hole height according to the present invention, wherein: the negative pressure side hole and the side hole are located on the same side.

[0014] As a preferred embodiment of the percutaneous nephroscope sheath with adjustable negative pressure suction side hole height described in this utility model, wherein: a sealing cap is connected to the top of the buckle, and a sealing cover is provided on the sealing cap.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The buckle is engaged in the side hole. The position of the buckle is adjusted up and down to adjust the height of the negative pressure side hole, which in turn adjusts the length of the stone fragment removal path and seals the sheath, enhancing the negative pressure suction efficiency. When negative pressure is not needed, the height of the side hole can be adjusted by adjusting the sealing strip. Attached Figure Description
