Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an extracorporeal lithotripsy auxiliary device. Background Art

[0002] Kidney stones are one of the most common diseases of the urinary system. Patients with kidney stones often have chronic diseases of the heart, brain, lungs, kidneys, endocrine system and other organs. The reserve capacity of important organs is poor, and the blood system is in a hypercoagulable state. The perioperative period is prone to the risk of worsening of underlying diseases and thromboembolism. The treatment methods for kidney stones with a diameter of 2.0 to 3.0 cm vary according to individual differences, mainly including percutaneous nephrolithotomy, microchannel percutaneous nephrolithotomy and ureteroscopic lithotripsy. Different procedures have their own advantages and disadvantages. With the upgrade of laser equipment and the improvement of flexible ureteroscope surgery, especially the widespread use of disposable electronic ureteroscopes, ureteroscopic treatment of kidney stones larger than 2 cm has achieved certain results.

[0003] Common complications of percutaneous nephrolithotomy for the treatment of kidney stones include bleeding, infection, vascular embolism, etc., and a long period of bed rest is required after the operation. Compared with standard channel percutaneous nephrolithotomy, microchannel percutaneous nephrolithotomy has the advantages of less damage, faster recovery, and lower bleeding rate. Therefore, it can be given priority for treating kidney stones less than 3 cm. Ureteroscopic lithotripsy is first used for kidney stones with a diameter of less than 2.0 cm, and is the second choice for kidney stones larger than 2.0 cm. It has the advantages of less trauma, high safety, faster postoperative recovery, fewer complications, and shorter hospitalization time. It has achieved good efficacy and safety in elderly patients with kidney stones and has certain advantages.

[0004] Based on the above, after using ureteroscopy lithotripsy to crush kidney stones, the gravel in the body will enter the urethra and be excreted from the body through the urinary tract. Existing patients usually accelerate the excretion of gravel in the body by jumping upwards to shake the body, but after undergoing ureteroscopy lithotripsy, the patient's body is relatively weak and unable to jump autonomously, resulting in the gravel in the body cannot be quickly discharged, affecting the patient's health.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] (1) The utility model is an extracorporeal lithotripsy assisting device, which uses a motor to drive the main shaft to rotate. The rotation of the main shaft drives a number of eccentric blocks on the main shaft to rotate together and perform eccentric motion. When the eccentric blocks perform eccentric motion, the main shaft is driven to vibrate up and down under the action of a spring. The elliptical blocks on the main shaft come into contact with a soft cushion during vibration, driving the soft cushion to vibrate together, thereby shaking the patient's body on the soft cushion, and assisting the doctor to expel the gravel in the patient's body more easily and quickly.

[0020] (2) The utility model provides an extracorporeal lithotripsy aid, in which a weight block inside the eccentric block moves in a movable groove in the direction of rotation of the eccentric block as the eccentric block moves eccentrically. The weight of the weight block can increase the amplitude of the eccentric movement of the eccentric block.

[0021] (3) The utility model is an extracorporeal lithotripsy assisting device. The universal ball on the stabilizing member rotates the sponge bar until it contacts the patient's body and then stops rotating. The sponge bar can then be fixed by the movable engagement between the buckle member and the slot member at the top of the sponge bar to prevent the sponge bar from shifting in position. The patient can be fixed with a telescopic strap and can cooperate with an auxiliary vibration mechanism. When the patient is discharged with the auxiliary vibration, the vibration force will not cause the patient's position to shift, thereby affecting the discharge of the lithotripsy.

[0022] (4) The utility model provides an extracorporeal lithotripsy aid, which uses the sponge material to ensure that the sponge rod will not cause harm to the patient when fixing the patient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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.

[0032] Embodiment 1:

[0033] See also Figure 1-Figure 5 An extracorporeal lithotripsy aid comprises a support base 1, an operating table 2 and a cushion 3. The operating table 2 is installed on the top of the support base 1, and the cushion 3 for allowing a patient to lie down is movably installed on the top of the operating table 2.

[0034] In this embodiment, the operating table 2 includes a mounting box 11, a vibrating member 12, an auxiliary member 13 and a motor 14. The mounting box 11 connected to the support base 1 is installed at the bottom of the operating table 2. Vibrating members 12 are symmetrically installed on both sides of the interior of the mounting box 11. An auxiliary member 13 is connected between the two vibrating members 12. A motor 14 is provided on one side of the mounting box 11. The output end of the motor 14 passes through the mounting box 11 and is connected to the auxiliary member 13.

[0035] In this embodiment, the vibrating member 12 is composed of a mounting frame 121, a spring 122, and a vibration seat 123. The mounting frame 121 is located on the mounting box 11. Springs 122 are installed at both upper and lower ends of the mounting frame 121. The vibration seat 123 is connected between the two springs 122.

[0036] In this embodiment, the auxiliary component 13 includes a main shaft 131, a sleeve 132, a connecting block 133 and an elliptical block 134. Both ends of the main shaft 131 are connected to the vibration seat 123, and are connected to the output end of the motor 14 through the vibration seat 123 so as to be rotated by the motor 14. The main shaft 131 is rotatably equipped with a sleeve 132, and the sleeve 132 will not rotate with the main shaft 131 when the main shaft 131 rotates. Connecting blocks 133 are fixed to the upper and lower ends of the sleeve 132, and the other end of the connecting block 133 is connected to the elliptical block 134.

[0037] In this embodiment, there are a number of eccentric blocks 21 arranged in an equidistant array on the main shaft 131, and a movable groove 22 is opened inside each of the eccentric blocks 21, and a weight block 23 is slidably fitted in the movable groove 22. When the main shaft 131 rotates driven by the motor 14, the eccentric blocks 21 thereon are driven to rotate together to perform eccentric motion. When the eccentric blocks 21 rotate, the weight blocks 23 located inside will move in the movable groove 22 in the direction of rotation of the eccentric blocks 21, thereby increasing the amplitude of the eccentric motion of the eccentric blocks 21.

[0038] Working principle: When the patient lies on the operating table 2 and completes the extracorporeal lithotripsy treatment and needs to discharge the gravel in the body, the motor 14 located at the bottom of the operating table 2 is driven to operate, and the motor 14 drives the main shaft 131 to rotate. As the main shaft 131 rotates, it drives the several groups of eccentric blocks 21 located thereon to rotate together and perform eccentric motion. When the eccentric block 21 rotates, the weight block 23 located inside will move in the movable groove 22 in the direction of rotation of the eccentric block 21. With the weight of the weight block 23, the amplitude of the eccentric motion of the eccentric block 21 can be increased;

[0039] When the eccentric mass 21 makes an eccentric motion, it will drive the main shaft 131 to make an eccentric motion together. Since both ends of the main shaft 131 are connected to the vibration seat 123, and the upper and lower ends of the vibration seat 123 are connected to the spring 122, the eccentric motion of the eccentric mass 21 will drive the main shaft 131 to vibrate up and down under the action of the spring 122. The elliptical block 134 installed on the main shaft 131 will contact the cushion 3 during vibration, driving the cushion 3 to vibrate together, and can shake the patient's body on the cushion 3, assisting the doctor to expel the gravel in the patient's body.

[0040] Embodiment 2:

[0041] See also Figure 6-Figure 7The utility model is an extracorporeal lithotripsy auxiliary device. Compared with the first embodiment, the present embodiment further includes: a plurality of fixing mechanisms 4 capable of fixing the patient are installed on both sides of the operating table 2. The fixing mechanisms 4 include a stabilizing member 41, a retractable strap 42, a buckle 43 and a slot 44. The stabilizing member 41 is symmetrically provided with two groups. The tops of the two groups of stabilizing members 41 are fixed with retractable straps 42 through slots. The retractable straps 42 are respectively installed with buckles 43 and slots 44. The buckles 43 can be movably engaged with the slots 44 to fix the patient.

[0042] In this embodiment, the stabilizing member 41 includes a base 51, a universal ball 52, a top block 53 and a sponge rod 54. The base 51 is fixed to the operating table 2. The universal ball 52 is rotatably engaged on the base 51. Top blocks 53 are connected to both sides of the universal ball 52. A sponge rod 54 is fixed on the top block 53. The sponge rod 54 will not cause harm to the patient when it comes into contact with the patient due to the sponge material.

[0043] In this embodiment, a positioning groove 441 is provided at one end of the slot member 44, and the positioning groove 441 can facilitate the locking member 43 to be positioned and engaged with the slot member 44. Limiting grooves 442 are provided on both sides of the slot member 44, and the limiting grooves 442 can fix the locking member 43.

[0044] Working principle: When the patient is on the operating table 2 and the gravel in the body is discharged with the assistance of the vibrating member 12 and the auxiliary member 13, the angle of the sponge rod 54 is adjusted by rotating the universal ball 52 on the stabilizing member 41, and the sponge rod 54 is rotated until it contacts the patient's body and then stops rotating. With the help of the sponge material, the sponge rod 54 will not cause harm to the patient when fixing the patient, and then the sponge rod 54 can be fixed by the movable engagement between the buckle member 43 and the slot member 44 at the top of the sponge rod 54 to prevent the sponge rod 54 from shifting in position. The patient is fixed by the telescopic strap 42, which can cooperate with the auxiliary vibration mechanism. When the patient is using the auxiliary vibration to discharge the gravel, the vibration force will not cause the patient's position to shift and affect the discharge of the gravel.
