Description

Technical Field

[0001] This utility model relates to the field of skeletal muscle fiber technology, and in particular to an auxiliary device for skeletal muscle fiber stripping. Background Technology

[0002] Skeletal muscle fibers are multinucleated cells, and the number of nuclei varies with the length of the muscle fiber; shorter fibers have fewer nuclei, while longer fibers can have 100 to 200 nuclei, located beneath the muscle membrane. The nuclei are oval-shaped, stain lightly, and have clearly visible nucleoli.

[0003] In medical research, to study muscle physiology, pathology, or to conduct cell culture, it is necessary to isolate and culture individual muscle fibers from skeletal muscle. To prevent muscle tissue from shifting, it is usually necessary to fix it. However, traditional muscle tissue fixation structures are inconvenient to operate and take a lot of time to adjust the position of muscle tissue.

[0004] Therefore, we propose an auxiliary device for skeletal muscle fiber stripping. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of fixing muscle tissue structures and the time-consuming nature of adjusting muscle tissue positions, by proposing an auxiliary device for skeletal muscle fiber stripping.

Each support component includes a base plate on the surface of the base, two vertical rods fixed on the surface of the base plate, a common support rod slidably connected between the two vertical rods, a threaded rod fixed on the top inner wall of the support rod, and an adjusting sleeve rotatably connected to the surface of the base plate. The threaded rod and the adjusting sleeve are threadedly connected.

[0009] It also includes two fixed blocks fixed to the surface of the base, the two fixed blocks are rotatably connected by the same rotating rod, a torsion spring is fixed between the rotating rod and the fixed blocks, at least one sliding sleeve is slidably connected to the outer wall of the rotating rod, a rectangular groove is opened on one side of the sliding sleeve, a Z-shaped pressure plate slides through one side of the rectangular groove, and a spring is fixed between the pressure plate and the sliding sleeve.

[0010] A limiting mechanism is provided on one side of the rotating rod to limit the sliding sleeve.

[0011] In one possible design, the limiting mechanism includes a connecting block and multiple slots. The connecting block is fixed to one end of the pressure plate, and two slots are fixed to one side of the connecting block. The multiple slots are evenly distributed on one side of the rotating rod, and one end of the slot passes through the rectangular groove and is located in the slot.

[0012] In one possible design, a sleeve is slidably fitted on the outer wall of the pressure plate, and a set screw is threaded through the surface of the sleeve, with the bottom end of the set screw abutting against the pressure plate.

[0013] In one possible design, the surface of the base plate has two through-holes, each containing a bolt, and the surface of the base has multiple threaded grooves, with the bolts and threaded grooves engaging.

[0014] In one possible design, the outer wall of the adjusting sleeve is integrally formed with two symmetrically arranged protrusions.

[0015] In one possible design, the outer wall of the support rod is fitted with a rubber sleeve.

[0016] In one possible design, the bottom of the base is provided with multiple rubber pads.

[0017] In this application, during use, the experimenter places the support rod in a suitable position according to their own usage habits, then uses bolts and corresponding threaded grooves to connect and limit the base plate, then rotates the adjusting sleeve, and adjusts the height of the support rod under the positioning of the vertical rod, then places the muscle tissue on the base, and then uses the pressure plate to drive the sliding sleeve and rotating rod to rotate, causing the torsion spring to deform, then pushes the pressure plate to make the locking block disengage from the locking groove, releasing the limitation on the sliding sleeve, then moves the sliding sleeve to a suitable position, then pulls the pressure rod to make the locking block engage with the corresponding locking groove, then lowers the pressure plate, the torsion spring drives the rotating rod to reset, and then drives the pressure plate to press the muscle tissue, and then uses tools to perform the peeling operation on the muscle fibers.

[0018] Beneficial effects: The skeletal muscle fiber stripping auxiliary device of this utility model can quickly release the fixation of muscle tissue through the setting of multiple structures such as sliding sleeve, rotating rod and pressure plate, so that people can adjust the position of muscle tissue and then quickly fix the muscle tissue, saving people's time.

A threaded rod 6 is fixed on the inner wall of the top of the support rod 5. An adjusting sleeve 7 is rotatably connected to the surface of the base plate 3. The threaded rod 6 and the adjusting sleeve 7 are threadedly connected. By rotating the adjusting sleeve 7, the support rod 5 can be raised or lowered, thereby adjusting the height of the peeling operation.

[0029] It also includes two fixed blocks 12 fixed on the surface of the base 1. The two fixed blocks 12 are rotatably connected to the same rotating rod 13. A torsion spring 14 is fixed between the rotating rod 13 and the fixed blocks 12. At least one sliding sleeve 16 is slidably connected to the outer wall of the rotating rod 13. A rectangular groove 21 is opened on one side of the sliding sleeve 16. A Z-shaped pressure plate 17 slides through one side of the rectangular groove 21. A spring 18 is fixed between the pressure plate 17 and the sliding sleeve 16. The torsion spring 14 can drive the rotating rod to rotate, thereby causing the pressure plate 17 to press the muscle tissue.

[0030] A limiting mechanism is provided on one side of the rotating rod 13 to limit the sliding sleeve 16. The limiting mechanism includes a connecting block 19 and multiple slots 15. The connecting block 19 is fixed to one end of the pressure plate 17. Two locking blocks 20 are fixed on one side of the connecting block 19.

The spring 18 can push the pressure plate 17, thereby causing the locking block 20 to engage with the slot 15, thus limiting the sliding sleeve 16 and preventing the pressure plate 17 from shifting, thereby stably fixing the muscle tissue.

[0031] This application can be used in the field of skeletal muscle fibers, or in other fields applicable to this application.
