DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution:

[0023] A costal cartilage harvester, please refer to Figures 1-7 It includes a cutting component and a hand gripper. The cutting component is located at one end of the hand gripper, and the doctor operates on the cutting component by holding the hand gripper.

[0024] The cutting component includes a mounting base 10 and a cutting blade 20. The cutting blade 20 is detachably connected to the mounting base 10. The cutting blade 20 includes a U-shaped blade 22 and a handle 21 fixed to the top of the blade 22. There are two handles 21 in total. The handles 21 are detachably connected to the mounting base 10. The blade 22 is fixedly connected to the handles 21.

[0025] Specifically, such as Figure 5 As shown, the mounting base 10 has notches 100 on both sides. The size of the notches 100 is adapted to the size of the tool holder 21. The distance between the two notches 100 is equal to the distance between the two tool holders 21. The two tool holders 21 can be placed in the two notches 100 respectively.

[0026] The mounting base 10 has an opening such as Figure 5 After the notch 100 is shown, a limiting flange is formed on the front side and top of the notch 100, and the tool holder 21 can abut against the flange after being placed in the notch 100.

[0027] The notch 100 is provided with a threaded groove 101, and the tool holder 21 is provided with a through hole 210. When the tool holder 21 is located in the notch 100, the through hole 210 corresponds to the threaded groove 101. It also includes a locking bolt 3, which passes through the through hole 210 and is threadedly connected to the threaded groove 101. The tool holder 21 can be stably fixed on the mounting base 10 by the locking bolt 3. The tool holder 21 and the blade can be removed from the mounting base 10 by unscrewing the locking bolt 3, which facilitates the replacement of the cutting blade 20.

[0028] The blade 22 includes a cutting edge and a back edge, with the back edge located on the front side and the cutting edge located on the rear side (i.e., on one side of the guide groove 102). The mounting base 10 has a lifting plate 50 on the side near the cutting edge and also includes an adjustment component for driving the lifting plate 50 to adjust its height.

[0029] The adjusting assembly comprises a threaded rod 60, a guide block 62 and a guide groove 102. The guide groove 102 is arranged on the mounting base 10 near the blade end, the threaded rod 60 is rotatably arranged in the guide groove 102, the bottom end of the threaded rod 60 is rotatably connected to the inner wall of the bottom of the guide groove 102 through a bearing, the top end of the threaded rod 60 penetrates out of the guide groove 102 and is fixedly connected with a knob 61, and the guide block 62 is slidably arranged in the guide groove 102 and is threadedly connected with the threaded rod 60. One side of the guide block 62 is fixedly connected with the lifting plate 50.

[0030] When the height of the lifting plate 50 needs to be adjusted, the doctor can drive the threaded rod 60 to rotate by rotating the knob 61, so as to drive the guide block 62 and the lifting plate 50 to lift and lower. When the lifting plate 50 is lowered to the height position of the blade end, the blade end is partially blocked, the effective use thickness of the blade end can be realized by adjusting the blocking of the blade end by the lifting plate 50, so that the rib cartilage of different thicknesses can be conveniently cut, the rib cartilage can be selected and cut according to the required amount of rib cartilage, rib cartilage is avoided from being cut too much to cause waste, and the relatively large surgical wound caused by cutting too much rib cartilage is avoided, and the damage degree to the human body is reduced.

[0031] The U-shaped blade 22 comprises two vertical parts, and the distance between the two vertical parts is less than or equal to the length of the lifting plate 50, so that the lifting plate 50 can block the blade end of the blade 22.

[0032] In the utility model, the distance between the lifting plate 50 and the blade is 0.5mm-1mm, so that the lifting plate 50 is avoided from directly rubbing against the blade during lifting.

[0033] It is worth mentioning that, in actual use, there are various styles of cutting knives, such as Figure 7 As shown in the figure, the distance between the two handles is fixed, and the distance between the two vertical parts of the blade can be changed.

[0034] The hand holding piece comprises an operating rod 40 and a handle 41. The operating rod 40 comprises a long rod part and a short rod part, the angle between the long rod part and the short rod part is 105°-135°, the end of the short rod part is fixedly connected to the top of the mounting base 10, and the handle 41 is sleeved on the long rod part and is fixedly connected with the long rod part. In this way, the hand holding piece and the cutting piece can maintain a certain angle, and the cutting operation is facilitated.
