Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a hepatobiliary and pancreatic clinical puncture sampling device. Background Art

[0002] When treating patients with diseases in the liver, gallbladder, pancreas, spleen and other parts of the body, medical staff need to diagnose the cause of the disease in the patient's liver, gallbladder, pancreas, spleen and other organs, and then treat according to the cause. When determining the cause, medical staff need to use a puncture needle to pierce the patient's abdomen, and make the needle tip of the puncture needle contact with the liver, gallbladder, pancreas, spleen and other organs, collect body tissues from the liver, gallbladder, pancreas and spleen, and then use the collected body tissues for testing; At present, in the field of hepatobiliary puncture, traditional puncture devices have many shortcomings. For example, in terms of puncture positioning, most traditional devices can only be adjusted in a single direction, which makes it difficult to find the best puncture position, which is not only time-consuming, but also may affect the accuracy of puncture and surgical efficiency. Existing puncture equipment often lacks flexible adjustment devices and cannot meet the sampling angle requirements of different patients and different surgical situations, which brings great limitations to surgical operations; Existing puncture devices usually require cumbersome medical preparation and sampling needle replacement processes, and cannot perform multiple samplings quickly and efficiently, affecting the continuity and efficiency of the operation; Traditional puncture devices usually cannot provide a low-temperature environment for the area where the sampling needle is located, which can easily cause the sample to lose its activity due to excessive temperature. It also cannot extend the storage time of the sample through a constant temperature environment, which is not conducive to subsequent inspection and analysis; In terms of patient experience, existing operating tables are usually relatively fixed and cannot be adjusted according to the patient's needs, making it difficult for patients to find a comfortable position during surgery. Especially when a specific sideways angle is required to ensure that the puncture site is facing upward, there is often a lack of effective auxiliary means, and additional items such as back pads are often required, which increases the complexity of surgical preparation and reduces patient comfort.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Example: See also Figure 1-9 ,This solution provides a clinical puncture sampling device, which is mainly used for liver, gallbladder, pancreas or similar lesions that require puncture. It can perform automated sampling and remote control sampling, reducing the preparation time and step conversion of medical staff during the operation, as well as the human cost investment of the hospital. The details are as follows; See also Figure 1-3 The device as a whole comprises an operating bed 10, on which an adjustment beam 50 and a sampling device 40 are arranged; the main body of the operating bed 10 comprises a bed board 102 and a bed body mounting frame at the bottom, and movable wheels 101 are arranged at the four corners of the bottom of the bed body mounting frame, and movable plates 103 are arranged at the head position and both sides of the bed board 102, and a hinge is arranged on one side of the movable plate 103 to connect with the bed board 102, and the movable plate 103 is lifted inward by the hinge; Three telescopic motors 104 are arranged at the bottom of the bed mounting frame, each of which corresponds to a movable plate 103. The top of the telescopic motor 104 is connected to the bottom of the movable plate 103, and a rotating shaft is arranged at the connection, so that the telescopic end of the telescopic motor 104 can rotate along with the movable plate 103. The function of the operating table 10 is to drive the flipping of the movable plate 103 through the workmanship of the telescopic motor 104, so as to help the patient turn sideways, or assist the patient to maintain a specific sideways angle, which is conducive to the smooth progress of the operation. In this way, when the patient is sampled, whether lying on his back or on his side, he can cooperate with the operating table 10 to ensure that the puncture site is facing upward while finding a suitable posture, thereby improving the patient's comfort during the operation without having to prepare additional items such as back pads, which is very convenient.

[0026] The sampling device 40 is the core of the device, see Figure 4-5 The sampling device 40 can move on the operating table 10 to find the position and angle of the operation through movement. The principle is: relying on the adjustment device 20 to complete the displacement adjustment in the horizontal and vertical directions, firstly, the adjustment beam 50 is installed on both sides of the operating table 10. The adjustment beam 50 is composed of a track 502 and a support frame 501. The support frame 501 supports the track 502 upward. The track 502 is parallel to the side of the operating table 10 and is slightly higher than the operating table 10. An adjusting device 20 is provided on the adjusting beam 50. The adjusting device 20 includes a longitudinal adjusting device 202 and a displacement block 201. The longitudinal adjusting device 202 includes a fixing block 203 and a mounting frame 209. The mounting frame 209 is sleeved on the track 502. Two driven wheels 204 are provided on the upper part of the mounting frame 502. A driving wheel 206 is provided on the lower part of the mounting frame 209. The driving wheel 206 and the driven wheel 204 are distributed in a triangle. A longitudinal driving motor 205 is fixed to the outer side of the mounting frame 209, and the driving end of the longitudinal driving motor 205 is connected to the driving wheel 206 and drives the driving wheel 206 to rotate. The driven wheel 204 and the driving wheel 206 are clamped on the top and bottom of the track 502 respectively, and extend the track 502 forward under the drive of the longitudinal driving motor 205. The two longitudinal driving motors 205 are synchronously controlled.

[0027] The principle of longitudinal adjustment is: the longitudinal drive motors 205 on both sides rotate synchronously and drive the driving wheel 206 to rotate. The driving wheel 206 is displaced under the restriction of the track 502 to achieve longitudinal movement; at the same time, the upper driven wheel 204 is also installed in the track 502, and is responsible for supporting the weight of the adjustment device 20, cooperating with the driving wheel 206 to move on the track 502. The weight of the adjustment device 20 is borne by the driven wheel 204, the track 502, and the support frame 501, which makes the longitudinal drive motor 202 bear a smaller load when starting or accelerating, consumes less energy, and the motor responds faster.

[0028] See also Figure 4-5 A lateral adjustment device is provided on the rear side of the opposite surfaces of the two fixed blocks 203, and the lateral adjustment device includes a lateral drive motor 207 and a lateral adjustment screw 208. The lateral drive motor 207 is fixed on the fixed block 203 on one side, and the driving end of the lateral drive motor 207 is fixed with the lateral adjustment screw 208, and the other end of the lateral adjustment screw 208 is installed on the opposite fixed block 203, and the lateral adjustment screw 208 passes through the extension block 212 and pushes the displacement block 201 to move by rotation.

[0029] See also Figure 6 , fixed blocks 203 are symmetrically arranged on the inner sides of the mounting frames 209 on both sides, and sliding rods 210 are arranged on the front sides of the opposite surfaces of the two fixed blocks 203. The displacement block 201 is sleeved on the sliding rod 210. The displacement block 201 includes a displacement frame 211 and an extension block 212. The extension block 212 is fixed on the rear side of the displacement frame 211; the sliding rod 210 can preferably use a glass sliding tube, and a lamp tube is arranged inside the sliding rod 210, which can play a role of lighting during surgery, killing two birds with one stone.

[0030] The principle of lateral adjustment is: after the lateral drive motor 207 is started, it drives the lateral adjustment screw 208 to rotate, and then the lateral adjustment screw 208 is based on the principle of thread ramp propulsion. When an object with a thread (the lateral adjustment screw 208) rotates in another object with a matching thread (a threaded hole that meshes with the lateral adjustment screw 208 is provided in the extension block 212), the spiral line of the thread will cause relative movement along the axial direction. At this time, the displacement frame 211 carries the sampling device 40 to make a lateral displacement, and the sliding rod 210 on the other side also cooperates with the sliding of the displacement frame 211; Based on the movement in the above two directions, the track 502 and the lateral adjustment screw rod 208 form an operating area, and the sampling device 40 can be moved to any position in the operating area, which is convenient for finding the puncture position during surgery, which is very efficient and convenient.

[0031] See also Figure 6 A sampling device 40 is provided in the middle of the displacement frame 211. The sampling device 40 includes a wheel, a rotating tube 403, and a fixed plate 404. Rotating shafts 405 are symmetrically provided on the left and right sides of the fixed plate 404. The rotating shafts 405 are movably embedded in the side wall of the displacement frame 211. An angle adjustment device 30 is provided on the right side wall of the displacement frame 211; The angle adjustment device 30 includes an angle drive motor 301, a worm 302 and a turbine 303. The driving end of the angle drive motor 301 is connected to the worm 302. The top of the worm 302 engages with the turbine 303. The turbine 303 is rotatably mounted on the displacement frame 211, and the turbine 303 is inwardly fixedly connected to the rotating shaft 405 on the right side. The sampling device 40 is driven to rotate by the rotation of the turbine 303 to achieve the purpose of adjusting the sampling angle. At the same time, an angle tilt sensor is provided on the sampling device 40. When the tilt angle of the sampling device 40 needs to be adjusted, the angle drive motor 301 is started to drive the worm 302 and the turbine 303 to rotate. The turbine 303 is fixed inwardly with the nearby rotating shaft 405, and the sampling device 40 is tilted by the rotation of the turbine 303. The angle tilt sensor is used to detect the angle tilt, which facilitates the adjustment of the tilt angle.

[0032] Sampling principle Figure 7A needle-pushing motor 406 is arranged at the center of the front side of the fixed disk 404. The needle-pushing motor 406 is a telescopic motor, and when the telescopic end extends downward, it abuts against the top of the sampling needle 70, pushing the sampling needle 70 downward to complete the puncture action. A laser positioning sensor 407 is arranged at the bottom of the needle-pushing motor 406 to detect objects under the needle-pushing motor 406. The principle is: the sensor emits a beam of laser, and the laser is reflected after being irradiated to the surface of the target object; the reflected light is received by the photoelectric detector inside the sensor, and it is measured whether there are obstacles within a short distance; using this principle, a reflective mirror is arranged on the top of the spherical head 701, and the reflected laser can determine that there is a sampling needle 70 under the needle-pushing motor 406, and the pushing action can be performed at this time.

[0033] See also Figure 8 The sampling needle 70 includes a spherical head 701 and a needle tube 702. The spherical head 701 is arranged at the top of the needle tube 702 and abuts against the top of the propulsion tube 402 when it is downward. The upper part of the needle tube 702 is conical and abuts against the conical spring 416 when it is downward. When there is no external force to propel the sampling needle tube 702, the sampling needle tube 702 is received in the propulsion tube 402 under the action of the spring 416.

[0034] An inner tube 414 is arranged in the inner cavity of the propulsion tube 402, and the inner tube 414 moves up and down in the inner cavity of the propulsion tube 402, and a spring 416 is arranged between the bottom of the inner tube 414 and the bottom of the propulsion tube 402, and a limiting ring is arranged on the top of the inner tube 414 so that the inner tube 414 is restricted in the inner cavity of the propulsion tube 402, and a conical cavity 415 is opened inside the inner tube 414, and a spring 416 is also arranged in the conical cavity 415, and the spring 416 in the conical cavity 415 is also conical, and a sampling needle 70 is inserted through the propulsion tube 402.

[0035] It should be noted that when the sampling needle 70 is pushed downward, the inner cavity spring 416 and the bottom spring 416 of the inner tube 414 are squeezed in turn, and the sampling needle 70 is extended outward at this time, and the extended distance can complete the puncture work; when the needle pushing motor 406 retracts upward, the sampling needle 70 is lifted upward driven by the two springs 416, and the rebound height at this time can retract the bottom end of the sampling needle 70 into the pushing tube 402, thereby protecting the needle tip and preventing it from being scratched again and interfering with the collected sample.

[0036] See also Figure 8The cross-sectional view of the propulsion tube 402 on the middle right side shows that when there is no external force pushing, a metal ring 418 and a magnetic ring 417 are provided at the top of the propulsion tube 402 corresponding to the tube body of the needle tube 702. When the sampling needle 70 is driven upward by the spring 416, the magnetic ring 417 will be adsorbed on either side of the metal ring 418, and the sampling needle 70 will be restricted by the mutual attraction between the metal ring 418 and the magnetic ring 417. In this way, when the sampling device 40 is tilted or rotated, the adsorption of the metal ring 418 and the magnetic ring 417 can fix the sampling needle 70 to prevent it from shaking.

[0037] Roulette replacement reference Figure 7 The sampling device 40 is provided with a wheel drive device to drive the rotation of the wheel to complete multiple collections. The wheel includes a fixed tube 401 and a propulsion tube 402. The propulsion tube 402 is provided with multiple and is fixed around the outside of the fixed tube 401. The fixed tube 401 is fixedly sleeved on the outside of the rotating tube 403. The rotating tube 403 is movably inserted in the fixed disk 404 and extends upward. The outer wall of the rotating tube 403 is provided with two limiting rings at the position of the fixed disk 404, and the limiting rings are clamped in the inner cavity of the fixed disk 404.

[0038] The roulette drive device includes a roulette motor 410, a roulette drive head 411 and a gear ring 408. The gear ring 408 is fixedly sleeved on the rotating tube 403. The roulette motor 410 is installed at the bottom of the fixed plate 404, and a roulette drive head 411 is extended downward from the top of the roulette motor 410. The roulette drive head 411 and the gear ring 408 are meshed with each other. The cyclic rotation of the propulsion tube 402 is controlled by rotating the rated angle of the roulette motor 410. Multiple samplings are achieved by replacing the sampling needle 70 under the push needle motor 406. If multiple samples need to be collected, the medical preparation and replacement time can be reduced, and the collection can be carried out directly, saving time and effort.

[0039] Sample Space Refrigeration Reference Figure 7-8 A refrigeration device is provided on the sampling device 40, and the refrigeration device is a refrigerator 412. The refrigerator 412 is installed on the top of the rotating tube 403, and fixed frames are provided on both sides. The bottom of the fixed frame is installed on the fixed plate 404.
