Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a multifunctional surgical device for percutaneous nephrolithotomy. Background Art

[0002] During percutaneous nephrolithotomy, we routinely lay the drape, and then stick the surgical film for brain surgery on the surgical field drape. The funnel part of the drape is not sealed, so it needs to be tied and then pierced with a syringe needle and placed in a sewage bucket. The funnel part of the drape and the water conduit part have no filtering components, so it is necessary to use gauze blocks to fill and filter the gravel. It is troublesome to remove the gauze blocks and gravel after the operation, which reduces the surgical efficiency of the surgeon. In addition, gravel is prone to fall during the process, resulting in a reduction in the number of stone specimens. We need to use a large amount of flushing fluid during the operation. If it is not drained in time, it may soak the surgical drape, pollute the operating room environment, and may even cause hypothermia in the patient during the operation, leading to many adverse outcomes. The opposite side is usually not equipped with a special water collection device or drainage funnel. If liquid overflows to the opposite side during the operation, it is easy to soak the surgical towel, which may lead to a series of adverse outcomes. Setting up additional water collection devices, drainage funnels or sewage buckets on the opposite side is not only cumbersome and time-consuming, but also takes up a lot of space in the operating room, making the operating room, which already requires a lot of space to place various operating systems required for percutaneous nephrolithotomy, even more cramped.

[0003] In addition, when performing percutaneous nephrolithotomy, we often need to use a variety of surgical supplies, such as blades, puncture needles, dilators, paraffin oil, etc. The placement of various surgical supplies during the operation brings inconvenience to the surgeon. Placing the curved tray on the patient's back may cause the risk of it falling, which may lead to contamination and waste of surgical supplies, and may even cause harm to the surgeon. On the other hand, the laser fiber is thin and easy to break. The inconvenience of fixation during the operation not only makes it easy to swing around, affecting the operation and even contamination, but also may cause accidental damage to the fiber.

[0004] In summary, the lack of products specifically for percutaneous nephrolithotomy causes many inconveniences in surgical preparation and during the operation, seriously delaying the smooth progress of the operation. Summary of the invention

[0005] In order to solve the above technical problems, the object of the present invention is to provide a multifunctional surgical device for percutaneous nephrolithotomy.
