Description

Percutaneous kidney puncture simulation box

Technical Field

The utility model relates to the field of surgical simulation instruments, in particular to a percutaneous nephropuncture simulation box.

Background

Nephrolithiasis and ureteral calculus are among the most common diseases in urology surgery, and percutaneous nephrolithotomy is one of the common methods for treating the diseases. The percutaneous nephrolithotomy has the advantages of small injury, light pain, thorough calculus removal, quick recovery and the like. Compared with laparoscopic calculus removal, percutaneous nephrolithotomy has little influence on the kidney and surrounding structures, and does not influence various renal operations in the future. Compared with the external lithotripsy, the method has short treatment period, instant effect and less influence on the kidney function.

Percutaneous nephrolithotomy, however, requires access to the renal congregation system from a suitable puncture route to avoid bleeding causing serious complications. The operation requires a doctor to find a proper puncture route, needle passage and target renal calyx, and requires certain clinical experience. For beginners of operations, a large number of in-plane and out-of-plane puncture operation exercises are needed for obtaining a breakthrough feeling during puncture, and the needle tip rubs the hand feeling of calculi so as to quickly improve the level of percutaneous nephroscopy of the beginners.

Referring to fig. 1, the present invention provides an embodiment of a percutaneous renal puncture simulation kit, which includes a kit body 1, at least one simulation stone 6, a balloon 5, a water inlet pipe 7 and a water outlet pipe 8.

One surface of the box body 1 is not sealed, and the unsealed surface is used for providing a puncture operation plane; a silica gel bottom layer 2, a gel layer 3 and a silica gel cover layer 4 are sequentially arranged in the box body 1 from bottom to top and are parallel to the unsealed plane of the box body 1. In the embodiment, the silica gel bottom layer 2 and the silica gel cover layer 4 are both made of soft silica gel, and the thickness of the silica gel bottom layer 2 is 1cm-2 cm; the silica gel cover 4 is 0.3cm to 1cm thick, wherein the silica gel cover 4 simulates the superstructure of the renal tissue through which the puncture needle passes, and also serves to close the casing 1 to prevent the gel layer gel from being squeezed along the casing wall to the outside of the casing. The gel layer 3 is an ultrasound-permeable gel, typically having a thickness of 2cm, and under ultrasound monitoring the gel layer 3 enables the practitioner to see where the puncture needle is located from the ultrasound monitoring screen.

A balloon 5 is arranged at the middle position of the silica gel bottom layer 2, and the balloon 5 penetrates through the upper surface of the silica gel bottom layer 2 and enters the gel layer 3; the balloon 5 is hollow inside. The balloon 5 is typically made of an elastic material, and in some embodiments may be directly selected.

Simulation stones 6 are arranged in the gel layer 3 close to the upper surface of the silica gel bottom layer 2 and inside the saccule 5, the simulation stones 6 simulate stones in kidney tissues, and when puncture needles of practicers penetrate through the simulation stones 6, hand feeling of stone puncture is obtained. In the sacculus 5 and outside the sacculus 5, the simulation stone 6 is provided with a plurality of blocks, and the diameter width of the simulation stone is not uniformly limited.

The water inlet pipe 7 and the water outlet pipe 8 penetrate through the box body 1 and are respectively connected with the saccule 5, so that the inside of the saccular structure is communicated with the outside of the box body 1. When puncture practice is carried out, water is injected into the balloon 5 from the water inlet pipe 7, and the balloon 5 filled with water is used for simulating the renal pelvis.

In one embodiment, the percutaneous nephropuncture simulation box further comprises a balloon 9, and the balloon 9 is connected with the tail end of the water outlet pipe 8. When puncture practice is carried out, water is injected into the sacculus 5 from the water inlet pipe 7 of the percutaneous kidney puncture simulation box, and if the puncture needle enters the sacculus 5, the water flows out of the puncture needle; if the puncture needle does not enter the balloon 5, the injected water flows into the balloon 9 through the water outlet pipe 8, so that the expansion degree of the balloon 9 can reflect the pressure of the injected water in the balloon 5; and can indirectly reflect whether the puncture is successful or not.

In one embodiment, the simulated stone 6 in the balloon 5 has a diameter width larger than the diameter of the water outlet pipe 8 and larger than the diameter of the water inlet pipe 7. The larger diameter width of the simulated stone 6 in the balloon 5 can effectively prevent the simulated stone 6 from being flushed out of the balloon 5 from the water outlet pipe 8 when water is injected into the balloon 5; when the water in the balloon 9 flows back into the balloon 5, the simulated stone 6 is flushed out of the balloon 5 from the water inlet pipe 7.

In one embodiment, the case 1 is a generally rectangular or cylindrical plastic case.

In one embodiment, the case 1 is a clear plastic case, and to some extent, the operator can view the possible locations of the puncture needle from the side of the clear plastic case 1.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the utility model, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
