Description

A visual and multifunctional kidney stone removal device

technical field

The present invention relates to the technical field of medical devices, in particular to a visual multifunctional kidney stone removal device.

Background technique

In the treatment of human kidney stones. At present, extracorporeal shock wave lithotripsy (ESWL) and surgical treatment are commonly used. Among them, surgical treatment is divided into open surgery and minimally invasive surgery. However, if kidney stones are combined with poor renal function, open surgery is still required, especially in county-level hospitals and poor people in my country. In some areas, minimally invasive surgery cannot be carried out, and open surgery is the main method. The most commonly used surgical method for kidney stones is stone removal through renal pelvis incision. The stone extraction surface of the existing clinically used kidney stone removal device is a flat surface with shallow horizontal stripes, and it is used to clamp kidney stones. The contact surface between the stone removal device and the stone is small, especially when the stone is located in the calices, the tip of the stone is often exposed In the renal pelvis or toward the renal pelvis, the space around the renal pelvis and calices is limited, and the stone removal device can only clamp one end of the calculus, and the calculus is easy to slip. Sometimes in order to prevent the calculi from slipping, forceps are used to clamp a part of the calculus, and sometimes the medical staff pinches the calculus manually, which is very cumbersome, time-consuming and laborious to operate, and adds great work difficulty to the medical staff.

Contents of the invention

The purpose of the present invention is to provide a visual and multifunctional kidney stone removal device to solve the above-mentioned technical problems.

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

A visible multi-functional device for removing stones from the kidney. The tail ends of the pliers handles are provided with collars, the left pliers handles and the right pliers handles are both hollow structures, the opposite surfaces of the left pliers handles and the right pliers handles are provided with meshing teeth, and the left pliers heads and the right pliers heads are Both are provided with holes, and the holes of the left and right pliers are covered with an elastic film. The connection between the right pliers and the right pliers handle is provided with a miniature camera and a miniature LED light. It is connected with the monitor and the power supply, the end of the left pliers head away from the left pliers handle is provided with a water outlet, and the left pliers handle is provided with a water inlet.

The elastic membrane is made of medical silica gel.

The left pincer head and the right pincer head are oval, square or round.

When in use, put the left and right forceps heads into the kidney, hold the left and right forceps handles and collars, turn on the micro LED lights and micro cameras to make them work, and illuminate the renal pelvis and calyces. In the case of the stone, move the left and right pincers to the stone and clamp the stone. At this moment, the elastic membrane expands according to the size of the stone and tightly wraps the stone so that it does not slip. Pull out the left and right pincers. Stones can be removed from the renal pelvis and calyces. This process uses the data transmitted by the micro-camera and optical fiber wires at the same time. The medical staff can observe the specific conditions in the renal pelvis and calyces through the monitor, and can accurately operate the stone removal device to forceps the stones, which greatly improves the The stone removal time is shortened, and through the display of the monitor, it can be accurately known whether there are stones remaining in the renal pelvis and calyces, which avoids the occurrence of stone residues after surgery.

When the observation is affected by blood stains around the stone extraction device, water can be injected into the left pliers handle through the water injection hole, and the water outlet hole at the top of the left pliers head will discharge water to remove the blood stains, which is convenient for observation.

Beneficial effect

1) In the present invention, a micro-LED light is installed on the stone removal device, which can illuminate the renal pelvis and calices during the intrarenal stone removal operation, which improves visibility, thereby shortening the stone removal time and reducing the risk of surgery , reduce the pain of patients, achieve the effect of surgery well, and the illumination is stable, no heating phenomenon, safe and reliable to use;

2). The invention adopts the receptive diastolic sleeve of the elastic membrane to remove stones, which is convenient for removing stones and greatly improves the work efficiency of medical staff;

3) The present invention has reasonable structure, novel design, strong practicability, long service life, convenient and fast use, and safety and sanitation.

Detailed ways

As shown in the figure: a visual multi-functional kidney stone removal device, including connecting the left forceps handle 1 and the right forceps handle 2 through the pin shaft 3, and the tops of the left forceps handle 1 and the right forceps handle 2 are respectively provided with a left forceps head 13 and a The right clamp head 5, the left clamp handle 1 and the bottom of the right clamp handle 2 are respectively provided with a collar 4, and the right clamp head 5 is provided with a miniature camera 8 and a miniature LED lamp 9, and the miniature camera 8 and the miniature LED lamp 9 pass through the optical fiber wire respectively. 10 Connect with display and power supply. The left pincer 13 and the right pincer 5 are all provided with holes, the opposite faces of the left pincer 13 and the right pincer 5 are provided with meshing teeth 6, and the holes of the left pincer 13 and the right pincer 5 are fixed with The elastic film 7, the elastic film 7 is made of medical silica gel, the left clamp head 13 and the right clamp head 5 are oval, the right clamp handle 2 is a hollow structure, one end of the optical fiber wire 10 is located in the hollow part of the right clamp handle 2, and the other end is in the pin The right pincer handle 2 passes through the shaft 3, and the left pincer handle 1 is a hollow structure. The left pincer handle 1 at the upper end of the pin shaft 3 is provided with a water inlet 11, and the top of the left pincer head 13 is provided with a water outlet 12, and the water inlet 11 and The water outlet 12 communicates through the hollow part of the left pincer handle 1 .

When in use, put the left clamp head 13 and the right clamp head 5 into the kidney, hold and operate the left clamp handle 1 and the right clamp handle 2 and the corresponding collar 4, turn on the micro LED light 9 and the micro camera 8 to make it work, Illuminate the renal pelvis and calices, so that under the condition of light, move the left forceps head 13 and right forceps head 5 to the stone and clamp the stone. At this moment, the elastic membrane 7 expands according to the size of the stone, tightly wrapping the stone so that it Without slippage, the stones can be removed from the renal pelvis and calyces by pulling out the left forceps head 13 and the right forceps head 5. This process uses the data transmitted by the micro-camera 8 and the optical fiber wire 10 at the same time, and the medical staff can observe the renal pelvis and calyces through the monitor.
