Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an infusion port bag positioning and volume measurement caliper kit. Background Art

[0002] The implantable venous infusion port is a completely implanted vascular access system that provides patients with long-term venous vascular access. The infusion port non-destructive needle is replaced every 7 days during the infusion. If the tube is blocked, the diluted urokinase 5000u / ml, 0.5ml can be injected into the PI CC lumen using negative pressure technology, and then withdrawn with a syringe after 15 to 20 minutes. If blood is drawn out, it means that the thrombolysis is successful.

[0003] Traditional infusion port implantation relies on manual positioning by experienced doctors, but due to differences in anatomical structures of different patients (such as changes in the position of the clavicle and acromion) and individual medical conditions, doctors often face challenges in selecting the location of the pouch. If the positioning is inaccurate, it may lead to adverse consequences such as catheter folding, pouch displacement, and surgical trauma, thus affecting the treatment effect and increasing the patient's pain and surgical risks.

[0004] According to the announcement number: CN217489437U, an infusion port puncture positioning device is provided, including a first clamp rod and a second clamp rod, one end of the first clamp rod and one end of the second clamp rod are movably riveted; it also includes a first measuring ruler and a second measuring ruler, the first measuring ruler is vertically connected to the first clamp rod, the second measuring ruler is vertically connected to the second clamp rod, and the first measuring ruler and the second measuring ruler form a cross. After the first clamp rod and the second clamp rod are respectively pressed against the injection seat of the circular structure of the infusion port, the utility model determines the center of the infusion port injection seat by the intersection of the first measuring ruler and the second measuring ruler. The infusion port non-destructive needle can be inserted through the intersection of the first strip through hole and the second strip through hole to achieve puncture into the center of the injection seat, thereby realizing the positioning function of the infusion port puncture and facilitating the puncture operation, avoiding multiple punctures caused by individual differences of patients, reducing costs and improving efficiency, and also reducing the risk of complications related to the patient's infusion port.

[0005] According to the positioning device introduced above, doctors need to perform manual positioning, but due to the differences in anatomical structures of different patients (such as changes in the position of the clavicle, acromion, etc.) and individual medical conditions, doctors often face challenges in selecting the position of the pouch. If the positioning is inaccurate, it may lead to adverse consequences such as catheter folding, pouch displacement, surgical trauma, etc., thus affecting the treatment effect and increasing the patient's pain and surgical risks.

[0035] By setting the measuring adjustment plate 1, the measuring plate ruler 2, the measuring support plate 3, the connecting plate 12 and the locking structure 4 for locking the adjusted position, as well as the cooperation between the first adjustment slot 5, the second adjustment slot 8, the third adjustment slot 11 and the fourth adjustment slot 13, the measuring caliper kit can change the position and angle according to the different structural differences of different patients, so as to adapt to the structural differences and individual medical conditions of different patients.

By setting the detection head 10, the volume of the capsular bag can be measured, so as to optimize the position selection of the capsular bag, avoid human errors, improve the safety and success rate of the operation, and enhance the treatment effect.

[0036] The adjustment structure 7 includes a movable seat 71, which is slidably connected to the inner cavity of the first adjustment groove 5. The surface of the movable seat 71 is bolted to one end of the laser marker 6. Both sides of the movable seat 71 are fixedly connected with connecting frames 72. The inner cavity of the connecting frame 72 is rotatably connected with a positioning block 73 through a damping shaft. The positioning block 73 is L-shaped, which pushes the movable seat 71 to move in the first adjustment groove 5, so that the movable seat 71 drives the laser marker 6 to move. After adjusting the position of the laser marker 6, the positioning block 73 is moved to make the positioning block 73 contact with the surface of the measuring and adjusting plate 1. By increasing the friction between the positioning block 73 and the measuring and adjusting plate 1, the movable seat 71 is positioned in the inner cavity of the first adjustment groove 5.

[0037] The mounting mechanism 9 includes a mounting seat 91, which is slidably connected to the inner cavity of the second adjustment groove 8, one end of the mounting seat 91 is bolted to one end of the detection head 10, and the other end of the mounting seat 91 is plugged and fixed with a threaded sleeve 92, the inner cavity of the threaded sleeve 92 is threadedly connected with a screw 93, the top of the screw 93 is fixedly connected with a button block 94, the bottom of the screw 93 is fixedly connected with a limit block 95, the outer surface of the screw 93 is rotatably connected with a positioning plate 96 through a rotating shaft, and both sides of the positioning plate 96 are fixedly connected with support blocks 97 , push the mounting seat 91 to drive the detection head 10 to move. After the position of the detection head 10 is adjusted, twist the button block 94 to drive the screw rod 93 to rotate. The screw rod 93 is connected with the threaded sleeve 92 through a thread, so that the screw rod 93 moves in the inner cavity of the threaded sleeve 92. When the screw rod 93 moves toward the threaded sleeve 92, the positioning plate 96 is pushed to move through the rotating shaft, so that the support block 97 contacts the surface of the measuring plate ruler 2, thereby increasing the friction between the support block 97 and the measuring plate ruler 2, so that the mounting seat 91 is positioned at the position of the inner cavity of the second adjustment groove 8.

[0038] A support rod 14 is fixedly connected to the surface of the positioning plate 96, and a through hole is opened on the surface of the mounting seat 91. The support rod 14 is inserted and slid into the inner cavity of the through hole of the mounting seat 91, and the other end of the support rod 14 is fixedly connected to a fixing block 15. Through the cooperation of the support rod 14, both sides of the positioning plate 96 are supported to prevent the positioning plate 96 from rotating through the rotating shaft when the screw 93 rotates, thereby improving the stability of the positioning plate 96 during movement and preventing angle deviation during movement.

[0039] A measuring protractor 16 is fixedly connected to one side of the measuring adjustment plate 1. The measuring protractor 16 is arranged in a semicircular shape. Through the arrangement of the measuring protractor 16, the measuring caliper kit can record the adjusted angle through the measuring bipod when adjusting the angle, thereby improving the accuracy of positioning.

[0040] A positioning groove 17 is provided on the surface of the measuring plate ruler 2, and the inner cavity of the positioning groove 17 is engaged with the support block 97. There are several groups of positioning grooves 17, and the several groups of positioning grooves 17 are equidistantly distributed on both sides of the second adjustment groove 8. Through the cooperation between the positioning groove 17 and the support block 97, the supporting force of the mounting seat 91 after positioning is increased, and the stability of the mounting seat 91 after positioning in the second adjustment groove 8 is improved.

[0041] A card slot 18 is provided on the surface of the measuring and adjusting plate 1, and the inner cavity of the card slot 18 is engaged with the positioning block 73. There are several groups of card slots 18, and the several groups of card slots 18 are equidistantly distributed on both sides of the first adjusting slot 5. Through the cooperation between the card slot 18 and the positioning block 73, the two sides of the moving seat 71 after positioning are supported, providing supporting force for the surface of the measuring and adjusting plate 1, so that the stability of the moving seat 71 after positioning in the first adjusting slot 5 is improved.

[0042] The locking structure 4 includes a support seat 41, a surface of which is fixedly connected to a fixing rod 42, the other end of which is fixedly connected to a fixing seat 43, a threaded groove is provided at one end of the fixing rod 42 close to the fixing seat 43, an outer surface of the fixing rod 42 is threadedly connected to an internal threaded tube 44, and the surface of the internal threaded tube 44 is rotatably connected to a locking seat 45 via a rotating shaft.

[0043] A positioning hole 19 is provided on the surface of the internal threaded tube 44, and a metal pin 20 is inserted and slidably inserted into the inner cavity of the positioning hole 19. A blind hole 21 is provided on the surface of the fixing rod 42, and the inner cavity of the blind hole 21 is engaged with the metal pin 20. A magnetic block 22 is provided in the inner cavity of the blind hole 21, and the magnetic block 22 is magnetically connected to the metal pin 20.

[0044] The surfaces of the support seat 41 and the locking seat 45 are both bonded with anti-skid pads 23, and the surfaces of the anti-skid pads 23 are provided with anti-skid patterns. Through the provision of the anti-skid pads 23, the friction between the support seat 41 and the locking seat 45 and the measuring adjustment plate 1, the measuring plate ruler 2, the measuring support plate 3 and the connecting plate 12 can be increased, while avoiding damage to the surface during locking, thereby improving the stability of the structure when the volume measuring caliper kit is locked.

[0045] During specific use, when adjusting the position and angle of the measuring caliper kit, rotate the internal threaded tube 44 to move the internal threaded tube 44 on the fixed rod 42, and the internal threaded tube 44 drives the locking seat 45 away from the surface of the measuring caliper kit to release the measuring caliper kit. At this time, the measuring adjustment plate 1, the measuring plate ruler 2, the measuring support plate 3 and the connecting plate 12 can be pushed for adjustment. After adjusting the position and angle between the measuring adjustment plate 1, the measuring plate ruler 2, the measuring support plate 3 and the connecting plate 12, the internal threaded tube 44 is rotated to drive the locking seat 45 to fit with the measuring caliper kit, and then the position and angle of the adjusted measuring caliper kit are positioned with the support seat 41 at the other end, and then the metal pin 20 is inserted into the positioning hole 19 and extended to the inner cavity of the blind hole 21 to be magnetically connected with the magnetic suction block 22. The measuring caliper kit can change its position and angle according to the structural differences of different patients, so as to adapt to the structural differences and individual medical conditions of different patients.

[0046] When adjusting the position of the laser marker 6, the movable seat 71 is pushed to move in the first adjustment groove 5, so that the movable seat 71 drives the laser marker 6 to move. After adjusting the position of the laser marker 6, the positioning block 73 is moved to make the positioning block 73 contact with the surface of the measurement adjustment plate 1. By increasing the friction between the positioning block 73 and the measurement adjustment plate 1, the movable seat 71 is positioned in the inner cavity of the first adjustment groove 5, so that the position of the laser marker 6 can be adjusted. The laser marker 6 can assist doctors in accurate marking.

[0047] The probe head 10 is made of flexible material and can be in close contact with the inner wall of the capsular bag to ensure the accuracy of the measurement data. The probe head 10 is embedded with a high-precision sensor module, which detects the geometry and volume of the capsular bag in real time through technologies such as ultrasound, pressure sensing or shape sensing. The shape design of the probe head 10 ensures that it can be easily placed in the capsular bag and complete accurate measurements without damaging the capsular bag, thereby optimizing the position selection of the capsular bag, avoiding human errors, improving the safety and success rate of the operation, and enhancing the treatment effect;

[0048] According to past experience and fixed points of the human body (points B and C in the illustration are fixed points of the human body, the end point of each person's shoulder is kept at the same horizontal position as the midpoint C. Point O is the 1 / 2 point of these two points, and point A is the puncture point during the actual operation. Based on the regional analysis of successful cases and failed cases, we found that the setting of the best port position is related to these points and the distance between them. The geometric relationship and analysis of successful cases indicate the area where the best position is located, and a two-dimensional rectangular coordinate system is established with the three-point BOC as the horizontal axis. The best port position is located on the DF horizontal line through angle restrictions and rib position restrictions, and the geometric relationship between each measured distance and the best port position point is expressed through the distance formula between two points in the plane rectangular coordinate system and the linear equation. (Combining experience with mathematics to scientifically quantify the positioning mode);

[0049] The points on the caliper are a mapping of the formula derivation and position determination. Similarly, first find the fixed point shoulder endpoint and the through center point. The active points and graduation values ​​on the caliper are used to collect and determine the relevant points, and then determine the port position through the previous angle limit and rib position limit. Fixed point (BOCA) - system construction - distance measurement (reading) - match these values ​​with the points on the caliper and find the best port area within the appropriate angle range. ① The caliper is not only a tool for fixing points ② It is also a ruler for distance measurement ③ The formula is based on the regional distribution characteristics summarized from successful cases and failed cases. Combining plane geometry with trigonometric functions and straight line equations, the position of the best port point is expressed through quantitative data. The formulas and equations involved are all commonly used formulas in plane geometry;

[0050] Suppose there are two points A and B with coordinates A(x 1 ,y 1 )、B、(x 2 ,y 2 ), then the distance between points A and B is:

[0051]

[0052] Specific adjustment method: The distance between BC points is different for different people, so the caliper must be suitable for most people. The choice of point position varies from person to person. Knob B can be used to measure and locate the BC distance first, and the knob O point is adjusted to the center of the BC segment. Then adjust and determine the position of the puncture point through point A. At this time, AD can determine the upper hypotenuse boundary of the port seat area, and the lower horizontal ruler is adjusted to the appropriate position and fixed through the rib positioning method. At this time, the area where this right-angled triangle is located is the key area for port seat installation. The caliper maintains a certain distance from the patient's chest surface and the caliper activity plane is basically parallel to the chest surface. First adjust the sliding knob to the corresponding position, compare the puncture point and the shoulder endpoint and the same horizontal central axis point, and move point O to the midpoint of BC at the same time. The angle should be less than or equal to 45°, and according to experience, translate the lower ruler to the position below the second row of ribs. The calibration and collection of the port seat area position can be completed.
