[0047] 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.

[0048] 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.

[0049] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0050] Example 1

[0051] Reference Figure 1 to Figure 3 , is the first embodiment of the present invention, which provides a liver disease puncture positioning frame, which includes an adjustment unit 1, including a fixing sleeve 11, a threaded sleeve 12 arranged on the inner side of the top of the fixing sleeve 11, a screw 13 arranged on the inner side of the threaded sleeve 12, a first bevel gear 14 arranged at the end of the screw 13, a second bevel gear 15 meshing with the first bevel gear 14, a transmission shaft 16 coaxially arranged with the second bevel gear 15, and a support frame 17 covering the outer side of the first bevel gear 14.

[0052] In this embodiment, the first bevel gear 14 and the second bevel gear 15 are linked to each other, and the screw 13 and the threaded sleeve 12 are linked to each other, so that the two sets of second bevel gears 15 can be driven to rotate simultaneously by rotating the transmission shaft 16, and then the heights of the screws 13 located on both sides of the detection bed can be adjusted synchronously, making the device simpler to operate, and the height of the positioning frame can be quickly adjusted.

[0053] It should be noted that the fixing sleeve 11 is a tubular structure with a hollow interior, and there are two groups of fixing sleeves 11 ; the two groups of fixing sleeves 11 are symmetrically arranged at both ends of the transmission shaft 16 .

[0054] Specifically, the diameter of the top of the fixed sleeve 11 is larger than the diameter of the rod, and the interior of the top is a hollow structure; the threaded sleeve 12 is arranged inside the fixed sleeve 11, and the threaded sleeve 12 can rotate along the axial direction of the fixed sleeve 11; the threaded sleeve 12 is connected to the fixed sleeve 11 through a limiter, so that the threaded sleeve 12 can only rotate along the axial direction of the fixed sleeve 11; a circular ring extends outward from the outer side of the top of the threaded sleeve 12, and the circular ring can ensure that the threaded sleeve 12 is located inside the fixed sleeve 11 and rotates.

[0055] An internal thread structure is provided inside the threaded sleeve 12, and the screw 13 is provided with an external thread structure that is compatible with the internal thread structure of the threaded sleeve 12; when the threaded sleeve 12 and the fixed sleeve 11 are relatively stationary, the screw 13 rotates and moves along the axial direction of the threaded sleeve 12; when the threaded sleeve 12 and the fixed sleeve 11 rotate relatively, the rotation of the screw 13 drives the threaded sleeve 12 to rotate synchronously.

[0056] The first bevel gear 14 is arranged at the end of the screw rod 13, and the first bevel gear 14 and the screw rod 13 are fixedly connected by a shaft key; the outer side of the top position of the screw rod 13 is a smooth rod-shaped structure; by installing the first bevel gear 14 on the top of the screw rod 13 and firmly combining it with the top of the screw rod 13 through a key, it is ensured that the two rotate synchronously.

[0057] The second bevel gear 15 and the first bevel gear 14 are arranged perpendicular to each other, and the second bevel gear 15 and the first bevel gear 14 are meshed with each other; and the second bevel gear 15 and the first bevel gear 14 cooperate with each other to convert horizontal rotation into vertical rotation, thereby achieving the problem of changing the rotation direction.

[0058] The transmission shaft 16 is a slender rod-shaped structure, and the transmission shaft 16 and the second bevel gear 15 are fixedly connected by a shaft key; the second bevel gears 15 are arranged at both ends of the transmission shaft 16; the corresponding first bevel gear 14 is arranged on one side of the corresponding second bevel gear 15; the two groups of first bevel gears 14 rotate synchronously in the same direction.

[0059] The support frame 17 is arranged outside the second bevel gear 15 and the first bevel gear 14 ; the support frame 17 can support the transmission shaft 16 .

[0060] The first bevel gear 14 passes through the bottom of the support frame 17 and extends into the interior thereof. The second bevel gear 15 is disposed on the side wall of the support frame 17 and supports the second bevel gear 15 through the side wall of the support frame 17, thereby ensuring that the second bevel gear 15 can rotate efficiently and stably.

[0061] Furthermore, the locking unit 2 includes a rotating member 21 disposed inside the fixing sleeve 11 , a locking block 22 disposed outside the rotating member 21 and in contact with the rotating member 21 , and a pressing member 23 linked to the locking block 22 .

[0062] In this embodiment, the locking block 22 is squeezed by the rotating member 21 so that the end of the locking block 22 can be moved away from the threaded sleeve 12; thereby, the limit on the threaded sleeve 12 can be released, so that the threaded sleeve 12 can rotate relative to the fixed sleeve 11; thereby, when the second bevel gear 15 rotates, the height displacement of the screw rod 13 will not move; thereby, it can effectively prevent medical staff from accidentally touching the handle when performing other work, causing the position of the positioning frame to shift.

[0063] It should be noted that the rotating member 21 is located inside the top of the fixed sleeve 11; and the rotation direction of the rotating member 21 coincides with the axis of the fixed sleeve 11; the position between the rotating member 21 and the fixed sleeve 11 is relatively fixed; so that the rotating member 21 can rotate relative to the fixed sleeve 11, but the vertical displacement between the rotating member 21 and the fixed sleeve 11 will not change.

[0064] There are multiple groups of locking blocks 22, which are arranged in a circular array inside the fixed sleeve 11. Under normal circumstances, the locking blocks 22 can fix the position of the threaded sleeve 12, so that the threaded sleeve 12 is in a stationary state relative to the fixed sleeve 11.

[0065] By cooperating between the pressing piece 23 and the locking block 22, and utilizing the cooperation between the pressing piece 23 and the positioning hole on the side wall of the fixing sleeve 11, the position of the rotating piece 21 can be positioned, thereby ensuring that the locking block 22 can release the limit on the threaded sleeve 12, thereby ensuring that the positioning frame in the appropriate position will not be offset.

[0066] In summary, the present invention can quickly and smoothly adjust the height position of the support frame through the adjustment unit, which is more convenient for medical staff to operate; at the same time, it can provide a more stable locking mechanism after reaching the predetermined position to avoid any position deviation caused by accidental touch; by enhancing the operational convenience and stability of the positioning frame, doctors can perform other operations without worrying about unexpected changes in the pre-set positioning, thereby ensuring the accuracy and reliability of the detection process.

[0067] Example 2

[0068] Reference Figure 2 - Figure 7 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: it also includes: the fixed sleeve 11 includes a cavity 111 opened at its end; the end of the threaded sleeve 12 is located inside the cavity 111; the threaded sleeve 12 is adapted to the screw rod 13; the screw rod 13 penetrates the threaded sleeve 12 and extends to the outside thereof.

[0069] In this embodiment, the cavity 111 is opened at the top of the fixing sleeve 11 ; and the opened cavity 111 can provide a certain space position for limiting the threaded sleeve 12 , so that the top of the threaded sleeve 12 extending outward can be located inside the cavity 111 .

[0070] Specifically, an internal thread structure is provided inside the threaded sleeve 12, and an external thread structure is provided on the outer wall of the screw rod 13, and the threaded sleeve 12 and the screw rod 13 are meshed; when the threaded sleeve 12 and the fixed sleeve 11 are relatively stationary, the rotation of the screw rod 13 will cause it to move along the axial direction of the threaded sleeve 12.

[0071] Furthermore, the second bevel gear 15 is located inside the support frame 17; the transmission shaft 16 passes through the second bevel gear 15 and extends to the inside thereof, and the transmission shaft 16 is connected to the second bevel gear 15; the transmission shaft 16 passes through the side wall of the support frame 17 and extends to the outside thereof.

[0072] It should be noted that the end of the second bevel gear 15 passes through the side wall of the support frame 17 and extends outward, and the side wall of the support frame 17 can provide a certain support for the second bevel gear 15; the second bevel gear 15 is sleeved on the outside of the rod portion of the transmission shaft 16, and the second bevel gear 15 and the transmission shaft 16 are interference fit, thereby realizing the synchronous rotation between the second bevel gear 15 and the transmission shaft 16.

[0073] The transmission shaft 16 passes through the side walls of the support frame 17 and extends to the outside thereof, and a handle is connected to one end of the transmission shaft 16, which can make it easier for medical staff to rotate the transmission shaft 16; the transmission shaft 16 can then drive the second bevel gear 15 to rotate; and the second bevel gear 15 is meshed with the first bevel gear 14, and the rotation of the second bevel gear 15 can drive the first bevel gear 14 to rotate.

[0074] Specifically, there are two groups of second bevel gears 15, and the two groups of second bevel gears 15 are symmetrically arranged at both ends of the transmission shaft 16; one group of transmission shaft 16 can drive two groups of second bevel gears 15 to rotate at the same time; and the rotation of the second bevel gears 15 can drive the two groups of screws 13 to move synchronously; and then the transmission shaft 16 can be driven to move to a suitable position.

[0075] Furthermore, the second bevel gear 15 is perpendicular to the rotation axis of the first bevel gear 14 ; the screw 13 cooperates with the threaded sleeve 12 , thereby enabling the screw 13 to rotate and move vertically along the axis of the threaded sleeve 12 at the same time.

[0076] It should be noted that the movement direction of the second bevel gear 15 is perpendicular to that of the first bevel gear 14 ; thus, the second bevel gear 15 rotating in the horizontal direction can drive the first bevel gear 14 to rotate in the vertical direction.

[0077] When the threaded sleeve 12 and the fixed sleeve 11 are relatively stationary, the screw 13 can move along the axial direction of the threaded sleeve 12 when it rotates; thus, the height of the screw 13 can be changed, thereby adjusting the position of the positioning frame to better facilitate operation by medical staff.

[0078] During use, the staff holds the handle to drive the transmission shaft 16 to rotate, and the transmission shaft 16 rotates and then drives the two groups of second bevel gears 15 arranged on the outside thereof to rotate, and the second bevel gear 15 rotates to drive the first bevel gear 14 meshing with it to rotate, and the first bevel gear 14 rotates to drive the screw 13 to rotate synchronously; when the position between the threaded sleeve 12 and the fixed sleeve 11 is relatively stationary, the screw 13 rotates and moves in the vertical direction along the axis of the threaded sleeve 12. In the process of rotating the transmission shaft 16, the two groups of screws 13 move synchronously, so that the height of the transmission shaft 16 can be adjusted, and then the position of the support frame arranged on the outside of the transmission shaft 16 can be adjusted.

[0079] In summary, holding the handle and rotating the transmission shaft 16, the transmission shaft 16 drives the two sets of second bevel gears 15 to rotate synchronously; the second bevel gears 15 can drive the screw 13 to rotate while rotating, and the screw 13 rotates and extends to move in the vertical direction of the axis of the threaded sleeve 12; and the two sets of screws 13 move synchronously, which can support the synchronous changes in the heights of both ends of the transmission shaft 16, and thus can effectively adjust the position of the positioning frame.

[0080] Example 3

[0081] Reference Figure 2 - Fig.10, which is the third embodiment of the present invention, is different from the previous two embodiments in that: it includes: a rotating member 21 that conflicts with the inner wall of the cavity 111; the threaded sleeve 12 includes a limiting tooth 121 arranged at its end; the rotating member 21 includes a conflicting surface 211 opened on its side wall, and a connecting rod 212 arranged on its side wall; the rotating member 21 and the limiting tooth 121 are located on the inner side of the cavity 111 and are arranged opposite to each other.

[0082] In this embodiment, the rotating member 21 is arranged inside the cavity 111, and the rotating member 21 can rotate along the axis of the fixed sleeve 11 during the rotation process inside the cavity 111; and the rotating member 21 and the fixed sleeve 11 are connected by a limit member, so that the vertical position between the rotating member 21 and the fixed sleeve 11 is relatively fixed, but the rotating member 21 rotates relative to the fixed sleeve 11.

[0083] Specifically, a limiting tooth 121 is arranged on the outer side of the top of the threaded sleeve 12, and the limiting tooth 121 is composed of multiple groups of teeth; the limiting tooth 121 and the rotating member 21 are arranged opposite to each other inside the fixed sleeve 11, and the two are respectively in contact with the inner wall of the cavity 111.

[0084] Furthermore, the fixing sleeve 11 also includes an articulated seat 112 arranged inside it; the locking block 22 includes a protrusion 221 arranged on the side wall, a limiting portion 222 arranged at the end of the locking block 22, and a torsion spring 223 arranged on the outside of the rotating shaft of the locking block 22; the locking block 22 is hinged and rotated with the articulated seat 112; the limiting portion 222 can be stuck in the tooth gap of the limiting tooth 121 through the torsional force of the torsion spring 223.

[0085] It should be noted that there is a certain gap between the side wall of the rotating member 21 and the fixing sleeve 11 , and the hinge seat 112 is arranged inside the gap; and the locking block 22 and the hinge seat 112 are hinged and rotated.

[0086] Specifically, the locking block 22 is an L-shaped structure, and the rotation axis of the locking block 22 is close to its middle position, and the protrusion 221 is located on the end side wall of the locking block 22. When the protrusion 221 is squeezed, the locking block 22 rotates along the rotation axis direction.

[0087] The other end of the locking block 22 is matched with the limiting tooth 121 , and the limiting portion 222 can be inserted into the tooth gap of the limiting tooth 121 , thereby limiting the rotation of the threaded sleeve 12 .

[0088] Under normal conditions, the torsional force of 223 can drive the locking block 22 to rotate along its axis, thereby causing the limiting portion 222 to flip toward the direction close to the limiting tooth 121, so that the limiting portion 222 can be inserted into the tooth gap of the limiting tooth 121, thereby limiting the threaded sleeve 12.

[0089] Furthermore, the abutting surface 211 abuts against the end of the protrusion 221 ; the rotation of the rotating member 21 can push the limiting portion 222 away from the tooth gap of the limiting tooth 121 .

[0090] It should be noted that the contact surface 211 is a curved arc surface, and the distance from one end of the contact surface 211 to the other end from the center of the rotating member 21 gradually increases; under normal circumstances, the end of the contact surface 211 closer to the center of the rotating member 21 corresponds to the position of the protrusion 221; at this time, the limiting portion 222 is inserted into the tooth gap of the limiting tooth 121.

[0091] During the rotation of the resistance surface 211, the position of its surface corresponding to the protrusion 221 gradually moves away from the center of the rotating member 21. As the rotating member 21 continues to rotate, the resistance surface 211 continuously squeezes the protrusion 221, so that the locking block 22 flips along its rotation axis, so that the limiting portion 222 gradually moves away from the tooth gap of the limiting tooth 121; thereby, the limiting of the threaded sleeve 12 can be released, so that the rotation of the screw rod 13 can drive the threaded sleeve 12 to rotate synchronously.

[0092] Furthermore, the fixing sleeve 11 also includes a waist hole 113 opened on its side wall; the connecting rod 212 passes through the waist hole 113 and extends to its outside; the pressing piece 23 includes an extrusion block 231 and a handle 232 arranged on the side wall of the extrusion block 231; the pressing piece 23 and the connecting rod 212 are hinged.

[0093] It should be noted that a waist hole 113 is opened on the side wall of the fixing sleeve 11, and the connecting rod 212 passes through the waist hole 113 and extends to the outside thereof; the connecting rod 212 is welded and fixed to the rotating part 21; the connecting rod 212 passes through the outside of the fixing sleeve 11, which makes it easier for personnel to control the rotation of the rotating part 21 from the outside.

[0094] Specifically, the pressing member 23 includes an extrusion block of a cam structure; the extrusion block can be used to limit the position between the pressing member 23 and the fixing sleeve 11, so that the position of the locking block 22 connected to the pressing member 23 can be fixed.

[0095] The handle 232 is welded and fixed to the extrusion block 231, and the handle 232 is an L-shaped structure; when the handle 232 is pressed down to make it parallel to the axis of the fixing sleeve 11, a certain gap may exist between the handle 232 and the side wall of the fixing sleeve 11, so that the handle 232 can be operated normally.

[0096] Furthermore, the waist hole 113 further includes a slot 1131 opened on the inner wall thereof; the extrusion block 231 is adapted to the slot 1131 ; the extrusion block 231 is inserted into the inner side of the slot 1131 , thereby being able to limit the rotation member 21 .

[0097] It should be noted that a card slot 1131 is also provided inside the waist hole 113; and the extrusion block 231 is adapted to the card slot 1131; the handle 232 and the connecting rod 212 are hinged and rotated; when the connecting rod 212 rotates, the end of the handle 232 can be driven to be inserted into the card slot 1131, thereby locking the position of the locking block 22.

[0098] Specifically, the end of the handle 232 is an inclined surface, and the size of the end is relatively small and then gradually increases; when the handle 232 is inserted into the slot 1131, the side wall of the handle 232 and the inner wall of the slot 1131 are gradually clamped together by friction, thereby locking the position of the locking block 22.

[0099] When in use, after the medical staff adjusts the transmission shaft 16 to an appropriate height, in order to prevent accidental contact when performing other work, the height of the screw 13 needs to be fixed; by turning the handle 232, the handle 232 drives the connecting rod 212 to move along the inner wall of the waist hole 113; the connecting rod 212 drives the rotating member 21 to move, so that the contact surface 211 gradually squeezes the end of the protrusion 221, and as the angle of rotation of the rotating member 21 rotates, the limiting portion 222 gradually moves away from the tooth gap of the limiting tooth 121; then, when the limiting portion 222 moves away from the inside of the limiting tooth 121, the handle 232 drives the connecting rod 212 to move to the position aligned with the card slot 1 131, and then flip the handle 232, so that the handle 232 drives the end of the extrusion block 231 to gradually get into the inner side of the slot 1131, and the extrusion block 231 and the slot 1131 are fixed by friction; so that the position between the extrusion block 231 and the fixed sleeve 11 is relatively fixed; ensure that the limiting portion 222 is in a state away from the limiting tooth 121, and the rotation of the threaded sleeve 12 is not restricted; when the screw rod 13 rotates, the threaded sleeve 12 rotates synchronously with the screw rod 13; at this time, the rotating transmission shaft 16 will not drive the screw rod 13 to change in height direction, thereby ensuring the height of the positioning frame is fixed.

[0100] On the contrary, the extrusion block 231 is taken out from the inside of the slot 1131, and then under the torsional force of the torsion spring 223, the end of the limiting portion 222 can be pushed to move in the direction close to the limiting tooth 121; during the resetting process, when the limiting portion 222 corresponds to the tooth tip of the limiting tooth 121, it is only necessary to rotate the screw rod 13 so that the tooth gap of the limiting tooth 121 corresponds to the limiting portion 222, so as to limit the threaded sleeve 12; ensuring that the screw rod 13 can move along the axial direction of the threaded sleeve 12 while rotating.

[0101] Example 4

[0102] Reference Figure 1 to Figure 3, which is the fourth embodiment of the present invention, is different from the previous three embodiments in that it includes a sliding unit 30, including a slide rail 31, a slider 32 arranged to slide inside the slide rail 31, a connecting member 33 connected to the slider 32, and a transverse moving member 34 sleeved on the outside of the support frame 17; the connecting member 33 is threadedly connected to the fixed sleeve 11.

[0103] In this embodiment, there are two groups of slide rails 31, and the two groups of slide rails 31 are respectively fixed to the two sides of the bed by bolts; and a slider 32 is arranged to slide inside the slide rail 31; the position between the slider 32 and the slide rail 31 can be fixed by pressing the inner wall of the track of the slide rail 31 with a screw rod passing through the inside of the slider 32.

[0104] Specifically, a screw hole is opened inside the slider 32, and a screw is arranged inside the screw hole, and a knob is arranged at the end of the screw, which can better facilitate personnel operation; by turning the knob, the screw is located in the screw hole of the slider 32 and spirally fed in, so that the end of the screw can contact the inner wall of the slide rail 31, and the position between the slide rail 31 and the slider 32 can be fixed.
