Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a hepatobiliary stone sampling device. Background Art

[0002] Intrahepatic bile duct stones are a type of bile duct stones, which refer to stones in the bile ducts above the confluence of the left and right hepatic ducts. It can exist alone or coexist with extrahepatic bile duct stones, which are generally bilirubin stones. Intrahepatic bile duct stones are often combined with extrahepatic bile duct stones, complicated by bile duct obstruction, inducing local infection and secondary bile duct stenosis, making it difficult for the stones to be discharged on their own, and the condition is prolonged and unhealed. For hepatobiliary stones, the commonly used treatment method is to vibrate the hepatobiliary stones to break them up and then remove them. Therefore, the patient needs to lie flat on the medical bed. The existing medical beds for hepatobiliary stone surgery require the patient to lie flat on the bed during actual use. For patients with hepatobiliary stone attacks, they cannot lie flat on the bed smoothly due to severe pain. For this reason, we propose a hepatobiliary stone sampling device to assist the patient to lie flat on the bed smoothly during the hepatobiliary stone sampling process. Utility Model Content

[0003] The purpose of the utility model is to provide a device for sampling hepatobiliary stones. The bed board assembly is in a horizontal state.

It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1 As shown, a hepatobiliary stone sampling device includes a bracket assembly 1, a bed board assembly 2 and a driving assembly 3 are movably provided on the bracket assembly 1, a seat board assembly 4 is movably provided on the bed board assembly 2, and the driving assembly 3 drives the bed board assembly 2 to rotate 90°. During the 90° rotation of the bed board assembly 2, the seat board assembly 4 is always horizontal.

[0022] like Figure 1 as well as Figure 2 As shown, in actual use of the present invention, in a normal state, the bed board assembly 2 is in a horizontal state. When a patient with hepatobiliary stones needs to be treated, the bed board assembly 2 is rotated from a horizontal state to a vertical state under the drive of the driving assembly 3, and the seat board assembly 4 is still in a horizontal state, and the seat board assembly 4 is perpendicular to the bed board assembly 2. The patient sits on the seat board assembly 4, and then under the drive of the driving assembly 3 again, the bed board assembly 2 returns to the initial horizontal position, and the seat board assembly 4 slowly returns to the initial state, so that the patient can lie smoothly on the bed board assembly 2.

[0023] like Figure 1 as well as Figure 2 As shown, the bracket assembly 1 includes a support leg 101 , the support leg 101 is provided with a cross bar 102 , a bolt block 103 is provided at the bottom of the support leg 101 , and a rotating shaft 104 is provided at the top of the support leg 101 .

[0024] like Figure 1 as well as Figure 2 As shown, in actual use, the support plate 201 rotates around the rotating shaft 104 through the rotating block 202 to realize the rotation of the auxiliary bed board assembly 2; in the utility model, by setting a bolt block 103 at the bottom of the support leg 101 and cooperating with the expansion bolt, the support leg 101 is detachably fixed on the ground, thereby increasing the stability of the equipment.

[0025] like Figure 3 as well as Figure 4 As shown, the bed board assembly 2 includes a support plate 201, a rotating block 202 is provided on the lower surface of the support plate 201, the rotating block 202 rotates around the rotating shaft 104, and a first rectangular groove is opened in the middle of the support plate 201; a sponge pad 203 is provided on the upper part of the support plate 201, and a second rectangular groove is opened in the middle of the sponge pad 203, the center point of the second rectangular groove is aligned with the center point of the first rectangular groove, and the size of the second rectangular groove is larger than the size of the first rectangular groove; the seat board assembly 4 includes a square plate 401 movably arranged inside the first rectangular groove, a sponge plate 402 is provided on the square plate 401, and the sponge plate 402 and the second rectangular groove are fitted together; the end of the rotating shaft 104 is fixedly connected to the top of the support leg 101, and a convex rod 304 is provided in the middle of the rotating shaft 104, the corners of the convex rod 304 are rounded, and the end of the convex rod 304 is adapted to the square plate 401.

[0026] like Figure 3 as well as Figure 4 As shown, in the present invention, since the size of the second rectangular groove is larger than that of the first rectangular groove, the sponge plate 402 can just be located inside the second rectangular groove, which firstly increases the comfort of the square plate 401, and secondly, during the relative rotation of the square plate 401 and the support plate 201, the gap between the square plate 401 and the first rectangular groove will not cause squeezing damage to the patient's skin.

[0027] like Figure 3 as well as Figure 4 As shown, in actual use of the present invention, a sponge pad 203 is provided on the support plate 201 to increase the comfort of the support plate 201. During the rotation of the support plate 201, the lower surface of the square plate 401 is always in contact with the arc-processed end of the convex rod 304. Supported by the convex rod 304, when the support plate 201 is rotated from a horizontal state to a vertical state, the square plate 401 gradually becomes perpendicular to the support plate 201 to form a sitting plate, so that the patient can sit on the sitting plate. Finally, when the support plate 201 is rotated from a vertical state to a horizontal state again, the square plate 401 is again level with the support plate 201, so that the patient can lie flat on the support plate 201.

[0028] like Figure 3 as well as Figure 4 As shown, the driving assembly 3 includes a first rotating seat 301 provided on the crossbar 102 and a second rotating seat 302 provided on the support plate 201 , and an electric telescopic rod 303 is connected between the first rotating seat 301 and the second rotating seat 302 .

[0029] like Figure 3 as well as Figure 4As shown, in actual use, when the output end of the electric telescopic rod 303 is output outward or retracted inward, the heel of the fixed end of the electric telescopic rod 303 rotates around the first rotating seat 301, and the end of the output end of the electric telescopic rod 303 rotates around the second rotating seat 302. As the output end of the electric telescopic rod 303 retracts inward, the support plate 201 rotates from a horizontal state to a vertical state. Similarly, when the output end of the electric telescopic rod 303 is output outward, the support plate 201 rotates from a vertical state to a horizontal state.

[0030] like Figure 1-4 As shown, the working principle of the present invention is as follows: first, in the initial state, the support plate 201 is in a horizontal state. When the patient with hepatobiliary stones needs to be treated, as the output end of the electric telescopic rod 303 contracts inward, the support plate 201 rotates from the horizontal state to the vertical state. Specifically, the support plate 201 rotates around the rotating shaft 104 through the rotating block 202. At the same time, the lower surface of the square plate 401 is always in contact with the arc-processed end of the convex rod 304, and is supported by the convex rod 304. When the state is rotated to the vertical state, the square plate 401 gradually becomes perpendicular to the support plate 201, forming a seat plate, so that the patient can sit on the seat plate. Then, when the output end of the electric telescopic rod 303 outputs outward, the support plate 201 rotates from the vertical state to the horizontal state. Finally, when the support plate 201 rotates from the vertical state to the horizontal state again, the square plate 401 is horizontal with the support plate 201 again, so that the patient can lie flat on the support plate 201. Finally, the doctor uses the instrument to vibrate and sample the patient's bile duct stones.

[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
