[0002] Urology is a hospital department that mainly diagnoses and treats diseases of the "surgical" part of the urinary system. It mainly treats various urinary diseases. Among them, urinary stones are one of the most common diseases in urology. When facing larger stones, an extracorporeal shock wave lithotripsy is usually used to vibrate the patient's stone site to break the stone and then discharge it through the urethra.

[0003] At present, when using an extracorporeal shock wave lithotripsy, the patient needs to lie on the treatment bed, and the stone is cracked and broken by relying on the stress effect of the focused high-energy pressure pulse on the stone. However, due to the lack of position limiter for the patient, on the one hand, it is easy for the patient's body to follow the shaking, thereby reducing the effect of the impact force, and on the other hand, it is easy for the patient's body to move and thus shift the stone crushing site. The patent document with the prior art publication number CN114652396A provides a clinical stone discharge device for urology. The document uses a restraining mechanism to facilitate the restraint and position limit of the patient's lower limbs and chest during use, so as to avoid the patient's subconscious movement due to discomfort during the treatment process, and ensure the accuracy of stone crushing.

[0004] Although the above literature has many beneficial effects, there are still the following problems: the restraining mechanism of the device can only limit the patient's chest vertically downward, and the single limit range can easily cause the patient's body to move horizontally, thereby reducing the effect of the device on crushing stones.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1

[0039] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a urology clinical stone discharge device, the urology clinical stone discharge device comprises a lithotripsy bed 1, and also comprises a connecting plate 2 arranged on the upper side of the lithotripsy bed 1, a vertical limit unit 4 is connected to the connecting plate 2, both ends of the connecting plate 2 are snap-fitted with mounting plates 5, the mounting plate 5 is installed on the side of the lithotripsy bed 1, and a horizontal limit unit 6 is connected to the mounting plate 5;

[0040] The vertical limiting unit 4 includes a chest limiting plate 401 provided on the lower side of the connecting plate 2;

[0041] The lateral limiting unit 6 includes a waist limiting plate 601, one side of the waist limiting plate 601 is connected to the mounting plate 5 through a scissor link 602, the scissor link 602 is in transmission cooperation with the connecting plate 2, and one side of the waist limiting plate 601 is rotatably connected to a driving column 603, and the driving column 603 is connected to a leg limiting plate 605 through a horizontal plate 604.

[0042] In the above technical scheme, after the connecting plate 2 is connected to the two mounting plates 5, a U-shaped structure is formed, and the vertical limiting unit 4 cooperates with the two horizontal limiting units 6 to realize the vertical and horizontal limiting of the patient lying on the lithotripsy bed 1, so that the treatment part of the patient's body is closely attached to the lithotripsy bed 1, and the vibration of the lithotripsy can effectively crush the patient's treatment part.

[0043] Specifically, the connecting plate 2 is connected to the mounting plate 5 and then descends, so that the chest limit plate 401 contacts the patient's chest. When the connecting plate 2 descends, it drives the scissor link 602 to extend, so that the waist limit plate 501 approaches the patient's waist until it contacts the patient's waist. The scissor link 602 drives the driving column 603 to rotate while extending, so that the cross plate 604 drives the leg limit plate 605 to move until the leg limit plate 605 contacts the patient's legs, thereby achieving three-point limiting of the patient's chest, waist and legs, so that the patient's treatment part can be effectively fitted with the lithotripsy bed 1, avoiding vertical shaking and lateral movement of the patient's body during the vibration process.

[0044] Through holes are provided at both ends of the connecting plate 2 , and the through holes are plugged and matched with the mounting plate 5 .

[0045] In the above technical solution, the through hole is inserted from the upper end of the mounting plate 5 and then descends to achieve the connection between the connecting plate 2 and the mounting plate 5 .

[0046] Among them, a plurality of mounting holes are opened at the lower end of the mounting plate 5, and the mounting plate 5 can be connected and fixed to the side of the crusher bed 1 by cooperating with the mounting holes and screws, or the mounting plate 5 can be clamped and fixed to the side of the crusher bed 1 by a clamp.

[0047] A locking assembly 3 is installed on the connecting plate 2, and the locking assembly 3 includes two T-shaped plates 301 slidably connected to the connecting plate 2. A tooth groove 302 is opened at one end of the T-shaped plate 301, and a tooth plate 501 is fixedly connected to one side of the mounting plate 5, and the tooth groove 302 is snap-fitted with the tooth plate 501.

[0048] In the above technical solution, a sliding hole is opened on the T-shaped plate 301, and the sliding hole is slidably connected to the slider provided at the bottom of the connecting plate 2. When the connecting plate 2 moves to an appropriate position on the mounting plate 5, the T-shaped plate 301 can move to one side of the mounting plate 5, so that the tooth groove 302 is engaged with the tooth plate 501, thereby limiting the lifting and lowering of the connecting plate 2, so that the connecting plate 2 and the mounting plate 5 are stably connected.

[0049] The locking assembly 3 also includes a hand wheel 303 rotatably connected to the connecting plate 2 , one end of the hand wheel 303 is fixedly connected to a limiting block 304 , the limiting block 304 abuts against the T-shaped plate 301 , and a spring 305 is elastically connected between the two T-shaped plates 301 .

[0050] In the above technical solution, the limit block 304 is of rectangular structure, and arc chamfers are provided at the corners. Turning the hand wheel 303 can drive the limit block 304 to rotate synchronously. When the width direction of the limit block 303 is toward the T-shaped plate 301, the spring 1 305 pulls the two T-shaped plates 301 closer to each other, so that the clamping connection between the tooth groove 1 302 and the tooth plate 501 is cancelled. When the length direction of the limit block 303 is toward the T-shaped plate 301, the limit block 304 T-shaped plate 301 moves toward the side of the mounting plate 4, so that the tooth groove 1 302 and the tooth plate 501 are clamped.

[0051] The two sides of the upper end of the scissor connecting rod 602 are respectively slidably connected to the waist limiting plate 601 and the mounting plate 5, and the two sides of the lower end are respectively hingedly connected to the waist limiting plate 601 and the mounting plate 5.

[0052] In the above technical solution, when the scissor link 602 is extended, the two sides of the upper end slide downward on the waist limit plate 601 and the mounting plate 5 respectively, thereby driving the waist limit plate 601 to translate, and the two waist limit plates 601 are close to each other to clamp and limit the patient's waist.

[0053] Both sides of the upper end of the scissor link 602 are rotatably connected with cross bars 606, and a driving plate 607 is fixedly connected to one cross bar 606. The driving plate 607 is slidably connected to the mounting plate 5 and abuts against the connecting plate 2; one end of the other cross bar 606 is fixedly connected to a driving rod 608, and a spiral groove 609 is provided on the driving column 603, and the driving rod 608 is slidably connected to the spiral groove 609.

[0054] In the above technical solution, when the connecting plate 2 moves downward on the mounting plate 5, it first contacts the driving plate 607, thereby driving the scissor link 602 to extend, and realizing the movement of the waist limit plate 601 toward the patient's waist. At the same time, the upper end of the scissor link 602 drives the cross bar 606 to descend, so that the driving rod 608 cooperates with the spiral groove 609 to drive the driving column 603 to rotate, so that the driving column 603 drives the leg limit plate 605 to move toward the patient's leg through the cross plate 604.

[0055] A connecting seat 610 is hinged at one end of the horizontal plate 604, and connecting rods 611 are slidably connected to the corners of the connecting seat 610. The connecting rods 611 are fixedly connected to the leg limit plate 605, and a plurality of springs 612 are elastically connected between the connecting seat 610 and the leg limit plate 605.

[0056] In the above technical solution, through the hinged cooperation between the horizontal plate 604 and the connecting seat 610, and the elastic connection between the connecting seat 610 and the second spring 612, the leg limiting plate 605 can be adaptively abutted and limited according to the position of the patient's legs.

[0057] A spring 3 613 is elastically connected between the waist limiting plate 601 and the mounting plate 5 .

[0058] In the above technical solution, when the waist limit plate 601 moves toward the patient's side, it drives the spring three 613 to stretch and store force. When the connecting plate 2 cancels the connection with the mounting plate 5, the spring three 613 contracts and drives the waist limit plate 601 to cancel the contact with the patient, and drives the scissor link 602 to contract, and at the same time makes the driving column 603 rotate in the opposite direction, so that the leg limit plate 605 cancels the contact with the patient.

[0059] It can be understood that the chest limit plate 401, the waist limit plate 601, and the leg limit plate 605 are all provided with arc-shaped recesses adapted to the human body on the side facing the patient, so that they can fit the patient's body better and improve the limiting stability. At the same time, cushioning soft bags are pasted on the arc-shaped recesses to avoid hard contact with the patient's body and improve comfort.

[0060] During use, after the patient lies flat on the lithotripter bed 1, the patient's treatment part is set on the upper side of the lithotripter working area, and then the connecting plate 2 is connected to the mounting plate 5 and the connecting plate 2 is lowered. The connecting plate 2 first contacts the driving plate 607, driving the scissor connecting rod 602 to extend, and at the same time driving the chest limiting plate 401 to contact the patient's chest. The scissor connecting rod 602 drives the waist limiting plate 601 to move to contact the patient's waist. At the same time, when the cross bar 606 descends, it drives the driving rod 608 to descend in the spiral groove 609, so that the driving column 603 is driven to rotate, and the driving column 603 drives the leg limiting plates through the cross plate 604. 605 moves to contact the patient's legs, and then the hand wheel 303 is rotated to drive the limit block 304 to abut against the T-shaped plate 301 in the length direction, and the tooth groove 302 on the T-shaped plate 301 is engaged with the tooth plate 501, so that the connection plate 2 and the mounting plate 5 are connected and fixed, and at the same time, the chest limit plate 401, the waist limit plate 601, and the leg limit plate 605 are limited. The patient is limited at multiple points through the chest limit plate 401, the waist limit plate 601, and the leg limit plate 605, so that the patient's treatment part only fits on the lithotripter bed 1, and the lithotripter can effectively crush the patient's treatment part after working.

[0061] Example 2

[0062] Reference Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: two limiting rods 402 are fixedly connected to the chest limiting plate 401, the limiting rods 402 are slidably connected to the connecting plate 2, and limiting grooves 403 are provided on opposite sides of the two limiting rods 402, and the T-shaped plate 301 is provided with a second tooth groove 306, which is snap-fitted with the limiting groove 403.

[0063] In the above technical solution, tooth groove 2 306 is arranged at one end of the sliding hole. When the T-shaped plate 301 moves toward the side of the mounting plate 5, tooth groove 1 302 and tooth plate 501 as well as tooth groove 2 306 and limiting groove 403 are synchronously engaged with each other, and the connection plate 2 and the mounting plate 5 are limited by the T-shaped plate 301 while limiting the chest limiting plate 401.

[0064] It can be understood that under the action of gravity, the chest limit plate 401 is in a suspended state through the limit rod 402. When the chest limit plate 401 contacts the patient and the connecting plate 2 descends, the upper side of the connecting plate 2 on the limit rod 402 moves. When the connecting plate 2 stops moving, the T-shaped plate 301 is engaged with the limit rod 402, so that the chest limit plate 401 and the connecting plate 2 become fixedly connected, thereby effectively limiting the patient's chest.

[0065] The remaining structures are the same as those of Example 1.

[0066] Example 3

[0067] Reference Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that two handles 307 are hinged on the handwheel 303, a torsion spring 308 is elastically connected between the handle 307 and the handwheel 303, and a plurality of positioning blocks 309 are fixedly connected at equal intervals on one side of the handle 307, and a plurality of positioning grooves 201 are opened on the connecting plate 2 in a circular shape at equal intervals.

[0068] In the above technical solution, when not affected by external force, the torsion spring 308 drives the handle 307 to rotate to fit with the connecting plate 2, so that the positioning block 309 is engaged with the positioning groove 201, and the rotation of the hand wheel 303 can be limited, thereby avoiding misoperation by medical staff. At the same time, the vibration caused by the operation of the crusher can be avoided to drive the hand wheel 303 to rotate, thereby improving the stability of the connection between the connecting plate 2 and the mounting plate 5.

[0069] The remaining structures are the same as those of Example 1.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
