DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 and Figure 2 As shown, an endoscopic lithotripsy machine comprises a body 1, wherein a plurality of circuit boards 2 with electronic components are arranged inside the body 1, and a heat dissipation element 3 for dissipating heat for the circuit boards 2; a display screen 4 is arranged on the front of the body 1, and an endoscope 5 and an electrohydraulic lithotripsy catheter are connected to the front of the body 1 via an adapter; a power cord 6 and an auxiliary control cord 7 are arranged on the back of the body 1, and the auxiliary control cord 7 is connected to a foot pedal 8; the heat dissipation element 3, the endoscope 5, the electrohydraulic lithotripsy catheter and the actuators of the foot pedal 8 are all electrically connected to the circuit board 2.

[0027] The endoscopic lithotripsy machine integrates the endoscope 5 and the electrohydraulic lithotripsy catheter into the same instrument, and can accurately locate the stones using endoscopic technology, and then use electrohydraulic lithotripsy technology to break the stones, which can accurately and effectively remove stones in human tissues, such as stones in the gallbladder system and urinary system. At the same time, the machine improves the body structure and the structure of the internal circuit board layout, making the structure of the entire machine more simple and beautiful, and having better stability and operability.

[0028] The endoscope 5 is a hose structure (with an operating handle), and a miniature camera is provided at its end, which can enter the human body through the human body channel. The hydraulic lithotripsy catheter is a small hose structure. The two can be arranged independently or integrated together, that is, the hydraulic lithotripsy catheter (in this case, it can be a hydraulic lithotripsy guide wire, a flexible thin-diameter electrode guide wire, which is provided with an electrode positive pole, an inner insulating layer, an electrode negative pole, an outer insulating layer and a lubricating layer from the inside to the outside, and the end of the electrode guide wire is connected to a lithotripsy machine) is passed through the channel hole of the endoscope 5 and enters the body through the endoscopic treatment hole. It will not affect the operation of the endoscope and can crush stones in any part visible under the endoscope. The entire lithotripsy process is carried out under the endoscope, and it is easy to grasp the treatment progress. The stones can be accurately positioned and the energy required for treatment can be stably output, which can not only ensure the lithotripsy effect, but also protect the human body to a great extent. It is less painful, the operation is safe and reliable, and the treatment effect is obvious.

[0029] By connecting the foot pedal 8 with the circuit board 2, the electrohydraulic lithotripsy system can be conveniently controlled. When the doctor is performing surgery, it is difficult to perform other operations because the doctor holds the handle of the endoscope or the electrode guide wire in his hand. Therefore, the foot pedal 8 can be used to control the electrode pulse of the electrode guide wire in the electrohydraulic lithotripsy system. The energy of the electrode pulse is adjustable between 0-400MJ. The control logic and mode are as follows:

[0030] Mode 1: Single pulse mode, when the pedal is pressed, the discharge electrode outputs only once;

[0031] Mode 2: Multi-pulse mode, when the foot pedal is pressed, the discharge electrode outputs twice;

[0032] Mode 3: Compound pulse mode, step on the pedal and the discharge electrode outputs four times;

[0033] Mode 4: variable frequency pulse mode, step on the pedal, the discharge electrode variable frequency output;

[0034] Mode 5: OOD pulse mode, step on the pedal and the discharge electrode will output variable amplitude.

[0035] The hydraulic-electric lithotripsy system preinstalled in the present endoscopic lithotripsy machine can preset or select parameters such as the number of discharges, the number of single discharge pulses, the interval between single discharge pulses, and the single discharge time through a program; these parameters can all be displayed on the display screen 4 for the operator to see intuitively, and the parameters can also be set and adjusted through the touch screen; the real-time images taken by the endoscope 5 can also be displayed on the display screen 4.

[0036] In order to ensure the normal working state of the all-in-one machine, the heat dissipation element 3 needs to be provided to dissipate heat from all its internal components, so as to prevent the internal temperature from accumulating and affecting the performance of the instrument, thus causing adverse effects on surgical treatment.

[0037] Furthermore, the circuit board 2 is connected to the inner side of the body 1 through a plurality of first vibration-damping support members 9, such as Figure 6 As shown, the first vibration-damping support member 9 includes a first inner connecting column 901 connected to the body 1 as a whole, a first outer vibration-damping column 902 is provided outside the first inner connecting column 901, and the circuit board 2 is connected and fixed to the first outer vibration-damping column 902 and the first inner connecting column 901 through a first connecting member 903.

[0038] The circuit board 2 is connected and installed by the first vibration-damping support member 9, which can not only stably connect the circuit board 2, but also maintain a certain distance between the circuit board 2 and the inner wall of the body 1, so as to avoid direct contact between the circuit board 2 and the body 1 and form a good air flow space, which is conducive to heat dissipation.

[0039] In some embodiments, the body 1 can be made of aluminum alloy material, which has a beautiful appearance after molding and is strong and durable; the first outer vibration damping column 902 is a plastic column, and the first connecting piece 903 is a plastic screw; the first inner connecting column 901 can be integrally formed with the body 1, and the plastic column is welded thereon to form a connecting support structure, and is connected with plastic screws. The non-rigid connection enables it to have certain vibration reduction and buffering capabilities, which can reduce the fluctuation of the circuit board when moving the entire all-in-one machine, and has good insulation performance.

[0040] Further, combined with Figure 7 and Figure 8 As shown, the heat dissipation element 3 includes a heat dissipation fan 301 and a fan base for mounting the heat dissipation fan 301, a plurality of connecting lugs 303 are provided on the periphery of the fan base, and the connecting lugs 303 are connected to the body 1 through a second vibration-damping support member 10; the second vibration-damping support member 10 includes a second inner connecting column 1001 connected as a whole with the body 1, a rubber column 1002 is provided on the outside of the second inner connecting column 1001, and the connecting lugs 303 are connected and fixed to the rubber column 1002 and the second inner connecting column 1001 through screws 1003.

[0041] For the cooling fan 301, the vibration is relatively large when it is working. The connection lug 303 and the second vibration-damping support 10 can effectively filter the vibration and reduce the vibration noise, while allowing sufficient space between the fan seat and the inner wall of the machine body to install the fan seat; the second vibration-damping support 10 is basically similar in structure to the first vibration-damping support 9, and the use of the rubber column has a stronger vibration-damping and buffering effect.

[0042] Furthermore, the fan seat includes an outer frame 302, the connecting lug 303 is arranged outside the outer frame 302, a cross heat sink 304 is arranged near the end surface of the outer frame 302, and a plurality of oblique heat sinks 305 are arranged between each partition of the cross heat sink 304 and the outer frame. The fan seat with this structure has a good heat dissipation effect and can quickly exchange heat with the air flowing therethrough.

[0043] Further, combined with Figure 3 to Figure 5 As shown, the body 1 includes a shell 101, a front panel 102 and an upper cover 103, the display screen 4 is embedded in the front panel 102, the endoscope 5 and the electrohydraulic lithotripsy catheter are connected and led out from the front panel 102, the power line 6 and the auxiliary control line 7 are led out from the rear of the shell 101, and a plurality of air inlet and outlet grilles 13 are provided at the rear and side of the shell 101, and the heat dissipation element 3 is arranged on the inner side of at least one of the air inlet and outlet grilles 13.

[0044] The shell 101 includes a bottom plate, two side plates and a rear panel, which are formed in one piece and then connected with the front panel 102 and the upper cover 103 to form the entire body structure. The connection method can be snap-on, screw connection, etc.; the corners of the shell 101 and the upper cover 103 are respectively rounded, which can make the entire appearance more rounded and beautiful.

[0045] Furthermore, the front panel 102 is arranged to tilt backward, with an angle greater than 60° with the horizontal plane, which makes it easy to view the display screen; a plurality of legs 11 are provided at the bottom of the shell 101, and inwardly recessed hand holes 12 are provided at the lower sides of the shell 101, which makes it easy to carry the all-in-one machine by hand.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
