Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a device for measuring the thickness of a hernia repair patch. Background Technology

[0002] A hernia occurs when a part of a human tissue or organ leaves its original location and enters another location through a gap, defect, or weak point in the body. Common types include inguinal hernias and incisional hernias. Hernia repair patches, as implantable medical devices commonly used in hernia surgery, are used to strengthen or repair weak areas of the abdominal wall to reduce the risk of hernia recurrence. They are usually made of polymer materials and can be divided into two types based on their structure: flat sheets and mesh plugs. The material properties must have good biocompatibility, tensile strength, and tissue integration ability to ensure long-term stability inside the body and not trigger a strong immune rejection reaction.

[0003] In hernia repair surgery, the thickness of the hernia repair mesh is a crucial parameter. If it's too thin, the mesh may not provide sufficient mechanical support, making it prone to deformation or even rupture under intra-abdominal pressure, leading to hernia recurrence. Conversely, if it's too thick, it increases the difficulty of the surgical procedure, making it difficult for the mesh to adhere to the body tissue, and may also trigger more severe foreign body reactions, affecting postoperative recovery and increasing patient discomfort and the likelihood of complications. Furthermore, different types of hernias and individual patient physiological differences require different mesh thicknesses. Therefore, accurately measuring the thickness of the hernia repair mesh is of great significance for ensuring product quality, meeting individualized clinical surgical needs, improving surgical success rates, and enhancing patients' postoperative quality of life.

[0004] Existing hernia repair patches can only measure the thickness of a single patch, requiring them to be placed one by one for measurement. This is inefficient, affects the progress of the measurement, and is not convenient for placing multiple patches simultaneously. Therefore, we propose a hernia repair patch thickness measurement device. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a method for simultaneously placing multiple repair pieces and then sequentially inspecting them; another purpose of this utility model is to provide a method for conveniently positioning multiple repair pieces.

[0006] Technical Solution: A hernia repair patch thickness measuring device includes a measuring instrument body. An L-shaped bracket is fixedly connected to the rear of the lower surface of the measuring instrument body. A shaft column is rotatably connected to the inner lower surface of the L-shaped bracket via a rotating shaft. A turntable is fixedly connected to the top of the shaft column. The upper surface of the turntable has multiple placement openings, and the outer wall of the turntable has multiple positioning holes. The number of positioning holes is the same as the number of placement openings, and their positions correspond one-to-one. A guide plate is fixedly connected to the inner upper surface of the L-shaped bracket behind the turntable. A positioning post is slidably connected to the inner side of the guide plate. A stop block is fixedly connected to the rear end of the positioning post. A spring is fixedly connected to the stop block on the opposite side of the guide plate and on the outer side of the positioning post.

[0007] Furthermore, a bearing seat is fixedly connected to the top of the measuring instrument body, and a connector is rotatably connected to the outer side wall of the bearing seat via a rotating shaft. A protective cover is fixedly connected to the bottom of the connector, and the protective cover is engaged with the front of the measuring instrument body.

[0008] Furthermore, a tapered positioning head is fixedly connected to the front end of the positioning post inside the positioning hole located behind the outer wall of the turntable.

[0009] Furthermore, a disc is fixedly connected to the center of the upper surface of the turntable, and multiple notches are formed on the outer side wall of the disc. A guide groove is integrally formed on the inner side wall of the notch near the center of the disc.

[0010] Furthermore, the interior of the notch is rotatably connected to a shaft via a pivot, and two arc-shaped pressure rods are fixedly connected to the outer wall of the shaft. A gear is fixedly connected between the two arc-shaped pressure rods on the outer wall of the shaft.

[0011] Furthermore, a guide rod is fixedly connected inside the guide groove, and an L-shaped rack is slidably connected to the outer wall of the guide rod, the L-shaped rack meshing with the gear.

[0012] Furthermore, a second spring is fixedly connected to the opposite side of the L-shaped rack and the guide groove, and to the outer side wall of the guide rod.

[0013] Furthermore, a rotating column is fixedly connected to the center of the upper surface of the disc, a knob is fixedly connected to the top of the rotating column, an extrusion disc is fixedly connected to the outer wall of the rotating column, and multiple extrusion heads are integrally formed on the outer wall of the extrusion disc.

[0014] Beneficial effects: The multiple placement ports on the turntable allow for the simultaneous placement of multiple hernia repair patches, greatly improving testing efficiency compared to traditional single-detection methods.

[0015] The design of the positioning hole, positioning post, conical positioning head, and spring one ensures that the turntable can be accurately positioned when it rotates to the appropriate testing position. When the turntable rotates to the correct position, the conical positioning head inserts into the positioning hole under the elastic force of spring one, effectively preventing the turntable from shifting during the testing process, ensuring the accuracy and stability of the testing, and also facilitating the placement of multiple repair pieces.

[0016] The combination of the notch on the disc, the arc-shaped pressure bar, the gear, the L-shaped rack, the spring, and the extrusion disc and extrusion head effectively limits the placement of the hernia repair patch within the insertion opening. When the knob is turned, causing the rotating column and extrusion disc to rotate, the extrusion head presses against the L-shaped rack, causing the L-shaped rack to slide along the guide rod and mesh with the gear. This, in turn, drives the shaft and the arc-shaped pressure bar to rotate, firmly pressing the hernia repair patch in place and preventing it from moving during the inspection process, thus further improving inspection accuracy.

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example:

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a hernia repair patch thickness measuring device is provided, including a measuring instrument body 1. An L-shaped bracket 2 is fixedly connected to the rear of the lower surface of the measuring instrument body 1. A shaft column 3 is rotatably connected to the inner lower surface of the L-shaped bracket 2 via a rotating shaft. A turntable 4 is fixedly connected to the top of the shaft column 3. Multiple placement openings 5 ​​are started on the upper surface of the turntable 4. Multiple positioning holes 6 are started on the outer side wall of the turntable 4. The number of positioning holes 6 is the same as the number of placement openings 5, and their positions correspond one-to-one. A guide plate 7 is fixedly connected to the inner upper surface of the L-shaped bracket 2 behind the turntable 4. A positioning post 8 is slidably connected to the inner side of the guide plate 7. A stop block 9 is fixedly connected to the rear end of the positioning post 8. A spring 10 is fixedly connected to the opposite side of the stop block 9 and the guide plate 7, and to the outer side of the positioning post 8.

[0027] A conical positioning head 14 is fixedly connected inside the positioning hole 6 behind the outer side wall of the turntable 4 at the front end of the positioning column 8.

[0028] The multiple placement ports 5 on the turntable 4 allow for the simultaneous placement of multiple hernia repair patches, significantly improving testing efficiency compared to traditional single-pattern testing methods. The coordinated design of the positioning hole 6, positioning post 8, conical positioning head 14, and spring 10 ensures precise positioning of the turntable 4 when it rotates to the appropriate testing position. Once the turntable 4 is in position, the conical positioning head 14, under the elastic force of the spring 10, inserts into the positioning hole 6, effectively preventing the turntable 4 from shifting during testing, ensuring accuracy and stability, and facilitating the precise placement of multiple repair patches.

[0029] like Figure 1 As shown, a bearing seat 11 is fixedly connected to the top of the measuring instrument body 1. A connector 12 is rotatably connected to the outer side wall of the bearing seat 11 via a rotating shaft. A protective cover 13 is fixedly connected to the bottom of the connector 12. The protective cover 13 is engaged with the front of the measuring instrument body 1.

[0030] The flip-up protective cover 13 can cover and protect the display surface of the measuring instrument body 1, while also making it easy to open the display.

[0031] like Figure 3 , Figure 5 and Figure 6 As shown, a disc 15 is fixedly connected to the center of the upper surface of the turntable 4. The outer wall of the disc 15 has multiple recesses 16. The inner wall of the recesses 16 is integrally formed with a guide groove 27 on the side near the center of the disc 15.

[0032] The inside of the notch 16 is rotatably connected to the shaft 17 via a rotating shaft. Two arc-shaped pressure rods 18 are fixedly connected to the outer wall of the shaft 17. A gear 19 is fixedly connected between the two arc-shaped pressure rods 18 on the outer wall of the shaft 17.

[0033] A guide rod 20 is fixedly connected inside the guide groove 27, and an L-shaped rack 21 is slidably connected to the outer wall of the guide rod 20. The L-shaped rack 21 meshes with the gear 19.

[0034] On the opposite sides of the L-shaped rack 21 and the guide groove 27, and on the outer side wall of the guide rod 20, spring 22 is fixedly connected.

[0035] A rotating column 23 is fixedly connected to the center of the upper surface of the disc 15. A knob 24 is fixedly connected to the top of the rotating column 23. An extrusion disc 25 is fixedly connected to the outer side wall of the rotating column 23. Multiple extrusion heads 26 are integrally formed on the outer side wall of the extrusion disc 25.

[0036] The combination of the notch 16, arc-shaped pressure bar 18, gear 19, L-shaped rack 21, spring 22, extrusion disc 25, and extrusion head 26 on the disc 15 effectively limits the placement of the hernia repair patch within the placement opening 5. When the knob 24 is rotated, causing the rotating column 23 and extrusion disc 25 to rotate, the extrusion head 26 presses against the L-shaped rack 21, causing the L-shaped rack 21 to slide along the guide rod 20 and mesh with the gear 19. This, in turn, drives the shaft 17 and arc-shaped pressure bar 18 to rotate, firmly pressing the hernia repair patch in place and preventing it from moving during the inspection process, thus further improving the inspection accuracy.

[0037] Workflow: First, multiple hernia repair patches are placed sequentially into the placement openings 5 ​​of the turntable 4. At this time, the arc-shaped pressure rod 18 is in its initial position under the action of spring 22, and will not obstruct the placement of the patches. Next, the stop block 9 is pushed to compress spring 10, causing the positioning post 8 and the conical positioning head 14 to retract from the positioning hole 6. Then, the turntable 4 is rotated, and the placement openings 5 ​​containing the hernia repair patches are rotated sequentially to below the detection area of ​​the measuring instrument body 1. When a placement opening 5 reaches the appropriate position, under the elastic force of spring 10, the conical positioning head 14 inserts into the corresponding positioning hole 6, fixing the turntable 4. Subsequently, the knob 24 is rotated, driving the rotating post 23 and the extrusion plate 25 to rotate. The extrusion head 26 on the extrusion plate 25 extrudes the L-shaped rack 21. The L-shaped rack 21 slides along the guide rod 20 and meshes with the gear 19, causing the gear 19 to drive the shaft 17 and the arc-shaped pressure rod 18 to rotate. The arc-shaped pressure rod 18 presses the hernia repair patch in the placement opening 5 tightly. At this point, the measuring instrument body 1 can perform thickness detection on the patch. After the detection is completed, rotate the knob 24 in the opposite direction, and the spring 22 pushes the L-shaped rack 21 to reset, and the arc-shaped pressure rod 18 releases the patch. Push the stop block 9 again, rotate the turntable 4, and rotate the next placement port 5 containing the patch to below the detection area. Repeat the above operation to achieve sequential detection of multiple hernia repair patches. The protective cover 13 is connected to the measuring instrument body 1 through the bearing 11 and the connector 12. When the measuring instrument body 1 is not in use, the protective cover 13 can be locked in front of the measuring instrument body 1 to protect the measuring instrument body 1 and prevent dust and other debris from entering and affecting the measurement accuracy.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
