Description

Technical Field

[0001] The invention relates to the technical field of cartilage sampling, in particular to a portable cartilage sampling device. Background Art

[0002] Cartilage is an important component structure in animals, mainly composed of chondrocytes and intercellular matrix. In the human body, cartilage is mainly distributed in the ears, nose bridge, throat, ribs and joints.

[0003] There are two main uses for sampling cartilage tissue: the first is to sample the cartilage for pathological examination when there is a lesion in the cartilage; the second is to sample the rib cartilage for ear or nose plastic surgery to prepare the corresponding plastic surgery material. Currently, cartilage sampling is mainly done by relevant personnel using a scalpel. Since cartilage tissue has a certain toughness, the scalpel is easy to slide when cutting, which can easily cause the operator to be scratched by the scalpel, especially when the cartilage tissue lacks reasonable fixation. This operation is more risky and requires the cooperation of multiple equipment and knives during the operation. These equipment and knives are not convenient to carry and can only be used in fixed places. The patent number is CN215019726U, and the patent name is "An Adaptive Cartilage Clamping and Cutting Operation Platform". The patent provides a device that can fix cartilage tissue and can also cut the cartilage tissue with a knife. However, the device still has many shortcomings. First, it is not convenient to fix and cut the patient's joints, but can only cut the removed rib cartilage into strips. Secondly, the cutting and fixing angles are single and the cutting angle cannot be adjusted. Finally, it is impossible to adaptively adjust the fixing and cutting areas according to the size and position of the cartilage tissue.

[0004] Therefore, we need a portable cartilage harvester to solve the problems of existing cartilage harvesting equipment being inconvenient to carry and difficult to use, which can effectively reduce the difficulty of cartilage harvesting and improve the safety of cartilage harvesting.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The connecting device 7 is arranged above the top frame 101, and a docking device 2 detachably connected to the connecting device 7 is fixed on the top frame 101. The connecting device 7 includes a connecting seat 702 fixed to the rotating shaft 602, and a gear 708 is rotatably installed in the connecting seat 702.

A docking seat 201 sleeved with the connecting seat 702 is fixedly installed on the top frame 101, and a rack meshing with the gear 708 is fixedly installed in the docking seat 201. 202, a pull handle 701 is slidably installed on the connecting seat 702, and a bevel limiting protrusion 705 that cooperates with the bevel clamping rod 707 is fixed at the end of the pull handle 701, and the bevel limiting protrusion 705 and the connecting seat 702 are connected through a third reset spring 703, and a limiting plate 710 for limiting the travel of the bevel limiting protrusion 705 is provided on the pull handle 701, and a bottom support frame 706 for limiting the rearward rotation position of the bevel clamping rod 707 is provided on the connecting seat 702, and a limiting rod 709 for limiting the forward rotation position of the bevel clamping rod 707 is fixedly installed on the connecting seat 702.The fixing process of the connecting device 7 and the docking device 2 is as follows: in the initial state, the torsion spring 704 will drive the gear 708 to rotate, so that the inclined clamping rod 707 will flip forward to the position in contact with the limiting rod 709, and at the same time, driven by the third return spring 703, the inclined limiting protrusion 705 will move toward the middle area of ​​the connecting seat 702 until the limiting piece 710 and the connecting seat 702 are released. When the docking seat 201 and the connecting seat 702 begin to be sleeved, the upper end of the docking seat 201 will first contact the inclined clamping rod 707 and start to push When the inclined plane clamping rod 707 is rotated, it can be ensured that the rack 202 can start to mesh with the specified teeth on the gear 708. Subsequently, as the docking seat 201 continues to move upward, the rack 202 can be used to drive the gear 708 to continue to rotate. When the inclined plane clamping rod 707 and the inclined plane limit protrusion 705 are released, since the contact surface between the inclined plane clamping rod 707 and the inclined plane limit protrusion 705 is an inclined plane, the force of the inclined plane clamping rod 707 continuing to rotate downward will be divided on the inclined plane to push the inclined plane limit protrusion 705 to move sideways. When the locking cam 707 is in the unlocking state, the locking cam 705 is in the unlocking state, and the locking cam 707 is in the unlocking state. The movement is respectively limited by the inclined limiting protrusion 705 and the bottom support frame 706, so the gear 708 will not be able to continue to rotate, and the docking seat 201 will not be able to move up and down, thereby fixing the docking device 2 on the connecting device 7. When the docking device 2 needs to be removed, it is only necessary to pull the handle 701 outward, so that the inclined limiting protrusion 705 can be separated from the limiting state of the inclined clamping rod 707, so that the gear 708 can rotate forward, and the docking seat 201 can be removed from the connecting seat 702.

[0043] In this embodiment, the position of the fixing device 1 can be adjusted by using the position adjustment device 8 and the steering adjustment device 6, and then the cartilage is clamped by the cartilage clamping device 3, and then the cartilage tissue is cut by using the cutting knife 10 which can adjust the position and cutting angle, thereby solving the problem that the existing cartilage sampling equipment is inconvenient to carry and difficult to use, and can effectively reduce the difficulty of cartilage sampling and improve the safety of cartilage sampling.

[0044] It should be noted that the portable cartilage device designed by the present invention can be set to different sizes and models, so as to be selected according to different situations, wherein the larger size model can be used for direct sampling of cartilage tissues grown in human or animal bodies, especially for convenient fixation and sampling of cartilage at limb joints, while the smaller size model can be used for sampling of cartilage on small animals such as rodents, and can also be used for secondary stripping of cartilage with larger size such as rib cartilage that has been removed. At the same time, the bottom sleeve 905 and the base 11 in the portable cartilage sampling device can be detachably connected, such as snap-on connection, etc., the top frame 101 and the bottom mounting plate 104 can also be detachably connected by bolts, etc., and the connecting platform 803 can also be removed from the end of the crossbeam 901, so that the entire device can be temporarily disassembled when not in use to reduce the space occupied by the device, and conveniently packed and carried using a small box body, of course, even if the device is not temporarily disassembled, the device itself has a smaller size and can be conveniently carried after being filled in the box body.

[0045] Example 2: Please refer to Figure 1 and Figure 2 On the basis of the first embodiment, at least two unit telescopic sleeves 903 are slidably sleeved and installed between the bottom sleeve 905 and the crossbeam 901 in sequence, and the unit telescopic sleeves 903 and the unit telescopic sleeves 903 and the bottom sleeve 905 are fixed respectively by corresponding unit fixing screws 904, and the crossbeam 901 and the unit telescopic sleeve 903 at the highest point are connected by the top fixing screw 902. In this way, the unit fixing screw 904 can be effectively used to adjust the installation height of the crossbeam 901, so that the operator can more conveniently place the cartilage tissue on the base 11, further solving the problem that the existing cartilage sampling equipment is inconvenient to carry and difficult to use, and can effectively reduce the difficulty of cartilage sampling and improve the safety of cartilage sampling.

[0046] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5On the basis of the second embodiment, the limiting clamping arm 605 and the rotating shaft 602 are connected by the second reset spring 603, and the side of the limiting clamping arm 605 is slidably installed with a ball head rod 604, and a compression spring for resetting the position of the ball head rod 604 in the limiting clamping arm 605 is installed between the end of the ball head rod 604 and the limiting clamping arm 605, and a clamping hole 808 for clamping with the ball head rod 604 is opened in the clamping groove 807, and the second reset spring 603 can effectively clamp the limiting clamping arm 605 in the clamping groove 807, and at the same time, the ball head The clamping fit between the rod 604 and the clamping hole 808 can also effectively prevent the limiting clamping arm 605 from escaping from the clamping groove 807. And because the end of the ball head rod 604 that contacts the clamping hole 808 is spherical, it is only necessary to apply a specified pulling force to the limiting clamping arm 605 to make the ball head rod 604 escaping from the clamping state with the clamping hole 808, thereby not affecting the normal use of the limiting clamping arm 605, further solving the problem that the existing cartilage sampling equipment is inconvenient to carry and difficult to use, and can effectively reduce the difficulty of cartilage sampling and improve the safety of cartilage sampling.
