Description

Technical Field

[0001] The invention relates to the technical field of animal tissue sampling, in particular to a multifunctional tissue sampler for animal experiment surgery. Background Art

[0002] In the field of biomedical research, tissue sampling of experimental animals is a key step in obtaining research samples. These samples are of vital importance to understanding disease mechanisms, drug action mechanisms, and developing treatment methods. To achieve this goal, researchers generally use various samplers to accurately sample animal tissues during experiments. Existing technologies, especially certain invention patents, have disclosed a variety of animal tissue sampling and processing technologies, aiming to improve sampling efficiency and sample quality.

[0003] The prior art discloses some invention patents in the field of animal tissue sampling and processing technology, among which the invention patent with application number 202322698239.8 discloses an animal tissue sampler, which relates to the field of animal tissue sampler technology, including a fixed sleeve, a stretching rod is arranged inside the fixed sleeve, a limiting slide groove is symmetrically arranged on the outer ring side of the stretching rod, a tension spring is arranged on the inner bottom side of the limiting slide groove, a limiting protrusion is arranged on the outer ring side of the stretching rod between the limiting slide grooves, a sampling needle is arranged at the lower end of the stretching rod, a sampling ring knife is arranged at the lower end of the sampling needle, an anti-slip ring is arranged on the inner ring side of the sampling ring knife, and the sampling needle can fix the sampling ring knife. The present invention is provided with a sampling ring knife and an anti-slip ring, so that when the sampling ring knife cuts and samples the tissue, the tissue sample is stably stuck on the inner side of the sampling ring knife under the action of the anti-slip ring, so as to prevent the sampled tissue from slipping off from the inner side of the sampling ring knife.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings: 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 in 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. The present invention is described in detail below based on the drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0018] The present invention provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, the multifunctional tissue sampler for animal experiment surgery includes a sampling tube 1, a sampling head 2 is arranged at the bottom end of the sampling tube 1, a push rod 3 is slidably connected inside the sampling tube 1, a fixing plate 4 is fixedly connected to the top of the push rod 3, an auxiliary structure 6 is fixedly connected to the outer surface of the sampling tube 1, a magnifying glass 8 is connected to the outside of the auxiliary structure 6, an adjusting structure 5 is arranged outside the sampling tube 1, a button 7 is arranged outside the sampling tube 1, the adjusting structure 5 is connected to the fixing plate 4, the adjusting structure 5 includes a threaded rod 1 501, a threaded rod 2 502 and a motor 503, the bottom end of the threaded rod 1 501 is transmission-connected with an anti-slip belt 506, the threaded rod 1 501 is externally threadedly connected to an L-shaped plate 1 504, and the threaded rod 2 502 is externally threadedly connected to an L-shaped plate 2 505.

[0019] like Figure 1 and Figure 2 As shown, threaded rod 1 501 is rotatably connected to one side of the outer surface of the sampling tube 1, threaded rod 2 502 is rotatably connected to the other side of the outer surface of the sampling tube 1, motor 503 is fixedly connected to the top of the sampling tube 1, the output shaft of motor 503 is connected to threaded rod 1 501, motor 503 drives threaded rod 1 501 to rotate forward and reversely, threaded rod 1 501 is connected to threaded rod 2 502 through anti-slip belt 506, one side of L-shaped plate 1 504 is connected to fixed disk 4, and the other side of L-shaped plate 2 505 is connected to fixed disk 4.

[0020] By providing the anti-slip belt 506, when the motor 503 drives the threaded rod 1 501 to rotate, since the threaded rod 1 501 is connected to the threaded rod 2 502 through the anti-slip belt 506, the threaded rod 1 501 and the threaded rod 2 502 will rotate synchronously, and the L-shaped plate 1 504 and the L-shaped plate 2 505 will move evenly on the surface of the threaded rod 1 501 and the threaded rod 2 502, which helps to reduce damage to the tissue during sampling because the uniform movement reduces the friction and shear force caused by speed changes.

[0021] like Figure 3 and Figure 4 As shown, the auxiliary structure 6 includes a telescope 601, which is fixedly connected to the outer surface of the sampling tube 1, a movable plate 602 is slidably connected inside the telescope 601, a guide rod 603 is rotatably connected inside the movable plate 602, a magnifying glass 8 is fixedly connected to the outer surface of the guide rod 603, a fixed column 605 is fixedly connected to one side of the movable plate 602, a ratchet 606 is rotatably connected to the outer surface of the fixed column 605, a coil spring 607 is connected to the outer sleeve of the fixed column 605, the ratchet 606 is connected to the fixed column 605 through the coil spring 607, a ratchet 604 is fixedly connected to one end of the guide rod 603, and the ratchet 604 overlaps the ratchet 606.

[0022] By setting the ratchet 604, the ratchet bar 606 and the coil spring 607, when a thrust is applied to the magnifying glass 8, the guide rod 603 will be driven to rotate in the movable plate 602. Since the ratchet 604 and the ratchet bar 606 are overlapped, when the magnifying glass 8 is flipped to the appropriate position, the ratchet bar 606 will overlap with the ratchet 604 through the action of the coil spring 607, so that the angle of the magnifying glass 8 after flipping can be locked, thereby preventing the magnifying glass 8 from being loosened due to the influence of external force.

[0023] The present invention provides a push rod, a fixed disk, an adjustment structure and a button. When the button is pressed, the motor will be driven to run, the motor will drive the threaded rod one to rotate, the threaded rod one and the threaded rod two will rotate synchronously, the L-shaped plate one and the L-shaped plate two will move on the surface of the threaded rod one and the threaded rod two, and the fixed disk will drive the push rod to slide in the sampling tube with the action of the L-shaped plate one and the L-shaped plate two. The sampler can realize the function of automatic reciprocating movement of the push rod in the sampling tube through the cooperation between the threaded rod one, the threaded rod two and the anti-slip belt, thereby reducing the need for manual operation, thereby reducing the labor intensity and fatigue of the operator, and can accurately control the sampling force and depth, reduce damage to tissues, improve sample quality, and reduce errors during operation.

[0024] The present invention arranges an auxiliary structure and a magnifying glass, drives a movable plate to move through a telescopic device, applies a thrust to the magnifying glass when the movable plate moves to an appropriate position, and the magnifying glass drives a guide rod to rotate inside the movable plate. Since the ratchet wheel and the ratchet bar overlap, the ratchet bar overlaps with the ratchet wheel through the action of a coil spring when the magnifying glass is flipped to an appropriate position, so that the magnifying glass can realize the function of angle adjustment, facilitates observation of the sampling head and the sampling area, and avoids the phenomenon of offset during the sampling process.

[0025] The present invention provides a multifunctional tissue sampler for animal experiment surgery, and the specific working principle is as follows: When the sampler is sampling animal tissue, the telescopic device 601 can drive the moving plate 602 to move. When the moving plate 602 moves to a proper position, a thrust is applied to the magnifying glass 8, and the magnifying glass 8 drives the guide rod 603 to rotate in the moving plate 602. Since the ratchet 604 overlaps with the ratchet bar 606, when the magnifying glass 8 is flipped to a proper position, the ratchet bar 606 overlaps with the ratchet 604 through the action of the coil spring 607. When the position adjustment of the magnifying glass 8 is completed, the sampling head 2 can be placed in the area where the animal needs to be sampled, and the contact surface between the sampling head 2 and the area can be observed through the adjusted magnifying glass 8. When the position of the sampling tube 1 is locked, the button 7 is pressed, and the button 7 will drive the motor 503 to run. The motor 503 will drive the threaded rod 1 501 to rotate. Since the threaded rod 1 501 is connected to the threaded rod 2 502 through the anti-slip belt 506, the threaded rod 1 501 and the threaded rod 2 502 will rotate synchronously, and the L-shaped plate 1 504 and the L-shaped plate 2 505 will move on the surface of the threaded rod 1 501 and the threaded rod 2 502. The fixed plate 4 will drive the push rod 3 to slide in the sampling tube 1 with the action of the L-shaped plate 1 504 and the L-shaped plate 2 505.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
