Description
Technical Field
[0001] This utility model relates to a puncture sampling device, specifically an auxiliary device for puncturing and sampling diseased tissues of human solid organs, belonging to the field of medical device technology. Background Technology
[0002] Human organ biopsy is a biopsy technique used to examine lesions in organs such as the lungs, liver, kidneys, and spleen. It involves taking tissue samples using a biopsy needle under the guidance of CT or ultrasound imaging and is an indispensable medical procedure for the detection of certain diseases.
[0003] Since most solid organs in the human body are protected by the skeleton, a certain angle of inclination is required during puncture to avoid the protective skeleton and reach the target lesion tissue; or because the lesion is small or there are important blood vessels or organs around the lesion that cannot be damaged, the needle needs to be precisely kept vertical, horizontal or at a certain angle during puncture; or the position of the lesion may change due to the patient's breathing force or body position during the puncture, requiring adjustment. Without auxiliary devices, the angle is often judged by personal feeling or experience.
[0004] Based on the above, after searching the solutions proposed in existing relevant patent projects, the actual finished products mostly have problems such as large size, high cost, difficulty in sterilization, difficulty in ensuring sterile operation, and the need for one or more assistants during operation, which cannot solve the problem better. Summary of the Invention
[0005] To address the problems mentioned above, this invention proposes an auxiliary device for puncturing and sampling diseased tissues from human parenchymal organs.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] A device for assisting in the puncture and sampling of diseased tissues in human solid organs is characterized in that it includes an angle measuring housing, a puncture needle mounting bracket is rotatably mounted on one side of the angle measuring housing, and a rotatable connecting member is provided between the angle measuring housing and the puncture needle mounting bracket.
[0008] Furthermore, the angle measuring housing is a colorless and transparent hemisphere, the angle measuring housing contains a low surface tension colored liquid with an air bubble inside, and the angle measuring housing is provided with an angle marking line on the outside;
[0009] Furthermore, the angle marking lines include meridians and parallels. When the circular bottom surface of the angle measuring housing is on a horizontal plane, the bubble is located at the highest point of the hemisphere of the angle measuring housing, and this point is marked as the pole. The center of the circular bottom surface of the angle measuring housing is the bottom point, and the line connecting the pole and the bottom point is one side of the angle. With the bottom point as the vertex of the angle, the angle increases in increments of 10°. The intersection of the other side of the angle on the wall of the angle measuring housing is the calibration point. Meridians or parallels are formed by connecting the same angle calibration points with the pole as the center.
[0010] Furthermore, the puncture needle mounting bracket is a rectangular hollow thin-shell structure with its long axis perpendicular to the circular bottom surface of the angle measuring housing. The top surface is located at one end of the angle measuring housing and is an open structure without any obstruction. The bottom surface is located at one end of the circular bottom surface of the angle measuring housing. A puncture needle hole is provided on the bottom surface of the rectangular block for the puncture needle to pass through. The rectangular hollow thin-shell structure is tightly filled with a fixing member. The long axis of the fixing member is consistent with the long axis of the rectangular hollow thin-shell structure. A puncture needle channel is provided inside the fixing member. The puncture channel is consistent with the long axis of the fixing member. The center point of the puncture needle hole on the bottom surface of the rectangular block is located on the long axis of the puncture needle channel.
[0011] Furthermore, the puncture needle channel is cylindrical, and the diameter of the puncture needle channel is the same as the diameter of the puncture needle. There are multiple fasteners of the same shape that can be replaced and inserted into the rectangular hollow thin-shell structure. Each fastener has a puncture needle channel. Different puncture needle channel diameters are adapted to different specifications of puncture needle diameters sold on the market. The appropriate fastener can be selected according to the model of the puncture needle, which is suitable for puncture needles of different thicknesses.
[0012] Furthermore, the fixing member is a soft rubber block or foam block with a puncture needle channel hole;
[0013] Furthermore, the device also includes guide strips of different diameters, the diameter of which is the same as the diameter of the puncture needle channel of the same diameter;
[0014] Furthermore, the rotating connector includes an outer disk mounted on the angle measuring housing, an inner disk capable of relative rotation is sleeved on the inner side of the outer disk, the inner disk is mounted on the puncture needle mounting bracket, and the rotation plane of the rotating connector is perpendicular to the circular bottom surface of the angle measuring housing.
[0015] Furthermore, the outer disk is provided with angle marking points. When the puncture needle mounting bracket is perpendicular to the circular bottom surface of the angle measuring housing, the outer disk is marked as 0°. When the puncture needle mounting bracket is parallel to the circular bottom surface of the angle measuring housing, the outer disk is marked as 90°. The outer disk between 0° and 90° is marked with points in increments of 10°.
[0016] Furthermore, the device also includes a fixing mechanism, which is used in combination with the angle measuring housing. When the fixing device is required, the fixing mechanism is installed below the angle measuring housing. The fixing mechanism includes a fixing base installed on the angle measuring housing. At least two fixing posts are evenly installed on the outer side of the fixing base. Each fixing post has a screw hole in the middle. A screw rod that mates with the screw hole is installed in the screw hole. An adhesive pad that can be adhered to the skin and reused is installed on the lower end face of the screw rod.
[0017] Furthermore, the fixed base is a circular hoop-shaped base with a hollow bottom surface, and the fixed base has a notch for installing a rotating connector;
[0018] Furthermore, a handle for easy operation is provided on the top of the screw.
[0019] Compared with the prior art, the advantages of this application are as follows:
[0020] 1. The finished product is small in size and light in weight. It is mainly attached to the puncture needle rather than fixed to the human body, and can move with the position of the puncture needle at any time.
[0021] Second, there are two methods to help determine the puncture angle of the puncture needle, which offer a wide range of choices and do not significantly increase the difficulty or cost between the two methods.
[0022] Third, the angle adjustment is simple to operate, does not require additional assistance, and the operator has a high degree of autonomy.

[0033] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0034] Example 1. As... Figure 1-2 As shown, an auxiliary device for puncturing and sampling diseased tissues of human solid organs includes an angle measuring housing 1, a puncture needle mounting bracket 2 rotatably mounted on one side of the angle measuring housing 1, and a rotatable connector 3 between the angle measuring housing 1 and the puncture needle mounting bracket 2.
[0035] The angle measuring housing 1 is a colorless and transparent hemisphere. The angle measuring housing 1 contains a low surface tension colored liquid and a bubble 11. An angle marking line 12 is provided on the outside of the angle measuring housing.
[0036] The angle marking line 12 includes meridians and parallels. When the circular bottom surface of the angle measuring housing 1 is on a horizontal plane, the bubble 11 is located at the highest point of the hemisphere of the angle measuring housing 1, and this point is marked as the pole. The center of the circular bottom surface of the angle measuring housing 1 is the bottom point. The line connecting the pole and the bottom point is one side of the angle. With the bottom point as the vertex of the angle, the angle increases in increments of 10°. The intersection of the other side of the angle on the wall of the angle measuring housing is the calibration point. Meridians or parallels are formed by connecting the same angle calibration points with the pole as the center.
[0037] Among them, such as Figure 7As shown, the puncture needle mounting bracket 2 is a rectangular hollow thin-shell structure with its long axis perpendicular to the circular bottom surface of the angle measuring housing 1. The top surface is located at one end of the hemispherical top surface of the angle measuring housing 1 and is an open structure without any obstruction. The bottom surface is located at one end of the circular bottom surface of the angle measuring housing 1. A puncture needle hole 22 is provided on the bottom surface of the rectangular block for the puncture needle to pass through. The rectangular hollow thin-shell structure is tightly filled with a fixing member 23. The long axis of the fixing member 23 is aligned with the long axis of the rectangular hollow thin-shell structure. A puncture needle channel 21 is provided inside the fixing member 23. The direction of the puncture needle channel 21 is aligned with the long axis of the fixing member 23. The center point of the puncture needle hole 22 on the bottom surface of the rectangular block is located on the long axis of the puncture needle channel 21.
[0038] The puncture needle channel 21 is cylindrical, and the diameter of the puncture needle channel 21 is the same as the diameter of the puncture needle. There are multiple fasteners 23 of the same shape that can be replaced and inserted into the rectangular hollow thin shell structure. Each fastener 23 has a puncture needle channel 21. The diameter of different puncture needle channels 21 is adapted to the diameter of different specifications of puncture needles sold on the market. The appropriate fastener can be selected according to the model of the puncture needle, which is suitable for puncture needles of different thicknesses.
[0039] The fixing member 23 is a soft rubber block or foam block with a puncture needle channel hole 24, such as... Figure 8 As shown;
[0040] The device also includes a guide bar of different diameters. The diameter of the guide bar is the same as the diameter of the puncture needle channel. Before installing the puncture needle, the guide bar is inserted and removed several times in the puncture needle channel 21 to enlarge the diameter of the puncture needle channel 21 slightly. When installing the puncture needle, the puncture needle can pass smoothly through the puncture needle channel 21.
[0041] The rotating connector 3 includes an outer disk 32 mounted on the angle measuring housing 1, with an inner disk 31 rotatable relative to the outer disk 32. The inner disk 31 is mounted on the puncture needle mounting bracket 2. The plane of rotation of the rotating connector 3 is perpendicular to the circular bottom surface of the angle measuring housing. Figure 3 As shown;
[0042] The outer disk 32 is provided with angle marking points. When the puncture needle mounting bracket 2 is perpendicular to the circular bottom surface of the angle measuring housing 1, the outer disk is marked as 0°. When the puncture needle mounting bracket 2 is parallel to the circular bottom surface of the angle measuring housing 1, the outer disk is marked as 90°. The outer disk is marked with points in increments of 10° between 0° and 90°.
[0043] If only one direction of needle angle adjustment is required, after the needle is securely fixed to the needle mounting bracket 2, rotate the connecting piece 3 to the desired angle according to operational needs. The operator holds the needle in their left hand and inserts it into the body. Using the puncture point as a fulcrum, the operator swings the biopsy needle back and forth towards or away from the operator, or left and right parallel to the line connecting the operator's shoulders. The bubble inside the angle measuring housing 1 will move accordingly. When it moves to the longitude and latitude lines marked with the corresponding angle, this is the required angle of the needle relative to the vertical plane. Then, according to the needs... To determine the required needle insertion depth for subsequent procedures, if the needle is tilted 30° away from the operator while remaining perpendicular to the horizontal plane, there is no need to rotate the connecting piece 3. The operator holds the needle in their left hand and inserts it into the body. During this process, ensure that the bubble in the angle measuring housing remains at its extreme point. Using the puncture point as a fulcrum, swing the biopsy needle away from the operator. The bubble in the angle measuring housing 1 will move accordingly. When it moves to the latitude line marked 30°, this is the required angle of the needle relative to the vertical plane. Then, proceed with the required needle insertion depth. If the puncture needs to be performed approximately horizontally, rotate the connecting piece 3 to turn the needle to 90° or another desired angle, and then adjust the insertion angle according to the measured angle as described above.
[0044] If multiple adjustments to the needle angle are required, after the needle is securely fixed to the needle mounting bracket 2, rotate the connecting piece 3 to the desired angle according to operational needs. The operator holds the needle in their left hand and inserts it into the body. Using the puncture point as a fulcrum, the biopsy needle is swung back and forth towards or away from the operator. The bubble in the angle measuring housing 1 will move accordingly. When it moves to the latitude line marked with the corresponding angle, this is the required sway angle between the needle and the vertical plane. Then, swing the needle left and right parallel to the line connecting the operator's shoulders. The bubble in the angle measuring housing 1 will move accordingly. When it moves to the longitude line marked with the corresponding angle, this is the required sway angle between the needle and the vertical plane. Then, proceed with subsequent operations according to the required needle insertion depth, such as when the needle is perpendicular to the horizontal plane. Tilt the needle 30° away from the operator, and simultaneously tilt it 45° to the operator's left while maintaining a vertical position. Do not rotate connector 3 at this point. The operator holds the needle in their left hand and inserts it into the body. During this process, ensure the bubble in the angle measuring housing remains at its extreme point. Using the puncture point as a fulcrum, swing the biopsy needle to the operator's left. The bubble in the angle measuring housing 1 will move accordingly. When it reaches the 45° latitude mark, the needle is at a 45° angle to the vertical. Then, using the puncture point as a fulcrum, swing the biopsy needle away from the operator, ensuring the bubble in the angle measuring housing 1 moves along the 45° latitude line. When it reaches the 30° longitude mark, this is the final required insertion angle. Then, proceed with the subsequent operations according to the required insertion depth. If puncture is required to be approximately horizontal, rotate connector 3 to turn the needle to 90° or another desired angle, and then adjust the insertion angle according to the measured angle as described above.
[0045] Example 2. (As shown) Figure 4 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that the device further includes a fixing mechanism 4. The fixing mechanism 4 is used in combination with the angle measuring housing 1. When the device needs to be fixed, the fixing mechanism 4 is installed below the angle measuring housing 1. The fixing mechanism 4 includes a fixing base 41 installed on the angle measuring housing 1. At least two fixing posts 42 are evenly installed on the outer side of the fixing base 41. Each fixing post 42 has a screw hole 43 in the middle. A screw 44 that cooperates with the screw hole 43 is installed. An adhesive pad 45 that can be adhered to the skin and reused is installed on the lower end face of the screw 44.
[0046] In this embodiment, three fixing columns 42 are used and are evenly distributed on the fixing base 41;
[0047] The adhesive pad 45 can be replaced by other adhesive alternatives such as medical tape or felt pads;
[0048] Among them, such as Figure 5As shown, the fixed base 41 is a circular hoop-shaped base with a hollow bottom surface, and the fixed base has a notch 46 for installing the rotating connector 3;
[0049] Among them, such as Figure 7 As shown, a handle 47 for easy operation is provided above the screw 44.
[0050] If, due to special circumstances, the angle measuring housing 1 cannot stabilize the puncture needle, and the fixing device 4 is required to determine the puncture needle angle, a cleaning rod can be repeatedly passed through the puncture needle channel in the puncture needle mounting bracket 2 to slightly enlarge the diameter of the puncture needle channel, ensuring that the puncture needle can pass through smoothly. Then, the angle measuring housing 1 is installed on the fixing base 41, and the connection between the connecting piece 3 and the angle measuring housing 1 is installed in the notch 46. After the puncture needle passes through the puncture needle channel, it is inserted into the human body. Then, the screw 44 is turned to adjust the posture of the entire device so that the bubble in the angle measuring housing 1 reaches the longitude and latitude marks on the spherical wall. This point represents the angle that is planned in advance. The screw 44 is attached to the surface of the human skin by the adhesive pad 45 to keep its position fixed. Then, the subsequent operations are carried out according to the required puncture needle insertion depth.
