DETAILED DESCRIPTION

[0027] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of 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.

[0028] Example 1

[0029] like Figures 1 to 3 As shown, an internal support styloid process cutter in an embodiment of the first aspect of the present invention includes a mounting frame 1, a support adjustment mechanism 18 is fixed to one end of the mounting frame 1, and a support sleeve 2 is installed on the outer side of the support adjustment mechanism 18, and the support adjustment mechanism 18 can be used to enable the support sleeve 2 to generate displacement capability, wherein the support adjustment mechanism 18 includes a support block 1801 and an active rod 1806 installed in the support sleeve 2, an active rod 1802 is installed on the inner side of the support block 1801, and one side of the active rod 1802 A first mounting wheel 1803 is meshedly connected, a second mounting wheel 1804 is connected to one side of the first mounting wheel 1803, and a third mounting wheel 1805 is meshedly connected to one side of the second mounting wheel 1804. The third mounting wheel 1805 is meshedly connected with the movable rod 1806, so that after the active rod 1802 rotates, the movable rod 1806 can be displaced, thereby driving the support sleeve 2 to move, so that the support sleeve 2 and the support block 1801 can support the human tissue around the styloid process, so that the styloid process is completely exposed;

[0030] The diameter sizes of the first mounting wheel 1803, the second mounting wheel 1804 and the third mounting wheel 1805 are arranged in order from small to large, so that the rotation speed of the active rod 1802 can be converted into the rotation efficiency of the third mounting wheel 1805 as minimized as possible, so that the moving efficiency of the movable rod 1806 is reduced, thereby avoiding the support sleeve 2 from moving too fast and causing accidental damage to the human tissue around the styloid process.

[0031] The other end of the mounting frame 1 is rotatably connected to a connecting rod 3, and a mounting ring 4 fixed to the outside of the mounting frame 1 is installed at the rotatable connection between the connecting rod 3 and the mounting frame 1. An angle adjustment mechanism 17 is fixedly installed on the inner side of the connecting rod 3 to control the rotation of the mounting ring 4, thereby controlling the rotation of the mounting frame 1. The mounting frame 1 is symmetrically arranged with respect to the angle adjustment mechanism 17. The angle adjustment mechanism 17 includes a mounting shell 1701. The inner side of the mounting shell 1701 is rotatably connected to a connecting wheel 1702, and the outer sides of the connecting wheels 1702 are respectively meshed with the corresponding mounting rings 4, wherein An adjusting rod 1703 is rotatably connected inside the connecting rod 3 on one side, and the adjusting rod 1703 and the mounting ring 4 form a worm gear connection, so that the adjusting rod 1703 can be rotated to drive the mounting ring 4 to rotate, so that the connecting wheel 1702 drives the mounting ring 4 on the other side to rotate in the opposite direction, thereby causing the mounting frame 1 to expand or tighten, expand the human tissue around the styloid process, and expose a good surgical field of view. At the same time, the worm gear connection formed by the adjusting rod 1703 and the mounting ring 4 allows the mounting ring 4 to have a self-locking structure without the need for further adjustment.

[0032] One end of the connecting rod 3 is rotatably connected to the mounting base 5, and a first rotation damper 6 is installed at the rotation connection between the mounting base 5 and the connecting rod 3, so that the mounting base 5 has a certain resistance when rotating, thereby reducing the rotation flexibility of the mounting base 5, improving a certain positioning effect, and preventing the device from rotating randomly between components after being erected;

[0033] like Figure 1 and Figure 4 As shown, the inner side of the mounting base 5 is slidably connected to a moving mechanism 7, and a connecting frame 8 is installed on the inner side of the moving mechanism 7, and the inner side of the connecting frame 8 is rotatably connected to a mounting rod 9, a fixed frame 22 is installed on one side of the mounting rod 9, and a restraining frame 23 is installed on the other side of the mounting rod 9, the longitudinal sections of the fixed frame 22 and the restraining frame 23 are both "V"-shaped, and the fixed frame 22 and the restraining frame 23 are symmetrically arranged about the center of the mounting rod 9, so that there can be a window structure between the mounting rods 9, which is convenient for the doctor to observe the current surgical field, and a limiting rod 19 is installed on the inner side of the fixing frame 22, and the outer surface of the limiting rod 19 is arranged in a stepped shape, and a connecting frame 8 is installed on the outer side of the limiting rod 19 The sleeve 11 has an hourglass-shaped through-hole structure on the inner side of the connecting sleeve 11, so that the connecting sleeve 11 can be rotated and adjusted in any direction on the outer side of the limiting rod 19. The outer side of the connecting sleeve 11 is provided with a holding rod 10, and the end of the holding rod 10 close to the supporting sleeve 2 is provided with a styloid process cutting mechanism, and the styloid process cutting mechanism includes a limiting sleeve mechanism 13 and a cutting blade 15 installed in a connecting tube 12. A cutting seat 14 is installed on the inner side of the limiting sleeve mechanism 13, and a piston rod 16 is installed at the end of the cutting blade 15 away from the cutting seat 14, and a connecting tube 12 opened in the holding rod 10 is provided on one side of the piston rod 16, and the connecting tube 12 is connected to an external air pump;

[0034] The moving mechanism 7 includes a mounting block 701, a second rotation damper 702 is mounted on the inner side of the mounting block 701, and the connecting frame 8 is mounted in a locking manner with the second rotation damper 702. The second rotation damper 702 plays the same role as the first rotation damper 6, preventing the connecting frame 8 from rotating randomly.

[0035] Specifically, after the supporting sleeve 2 completes the support, the operating physician holds the holding rod 10 and operates the position of the styloid process cutting mechanism. When the limiting sleeve mechanism 13 is sleeved to the outside of the styloid process, the cutting position is aligned with the cutting seat 14, and the external air pump is operated to make the piston rod 16 move rapidly under the action of air pressure, so that the cutting blade 15 cuts off the styloid process and can keep the styloid process in the limiting sleeve mechanism 13 to avoid falling into the patient's body.

[0036] like Figure 5As shown, the limiting sleeve mechanism 13 includes a truncation sleeve 1301, one end of which is threadedly connected to a closing cover 1302, so that the distance between the top of the inner wall of the closing cover 1302 and the truncation seat 14 can be adjusted, thereby being able to be adjusted directly according to the length of the styloid process that needs to be truncated;

[0037] Specifically, when the top of the styloid process contacts the top of the inner wall of the closing cover 1302, the truncation sleeve 1301 cannot move downward along the outer side of the styloid process, so that the distance between the top of the styloid process and the truncation seat 14 is fixed, and then the truncation is performed, so that the truncation operation can be achieved more accurately, and at the same time, the truncated part of the styloid process can be completely wrapped to the inside of the truncation sleeve 1301, and the upper end opening of the truncation sleeve 1301 is closed by the closing cover 1302 to further prevent the truncated part of the styloid process from falling off.

[0038] The technical effect achieved by the above embodiment is: the human tissue around the styloid process can be supported to expose a good surgical field of view, and at the same time, the styloid process can be cut off under the limit of the support, so that the doctor can perform the operation alone without the need for an assistant to open and support the surgical field of view;

[0039] Most accessories are easy to disassemble, making it easier to clean and disinfect, as well as replace some parts.

[0040] Example 2

[0041] like Figure 3 As shown, an internal support styloid process cutter includes all the contents of Example 1. In addition, a connecting tube 20 is installed on one side of the mounting frame 1, and the connecting tube 20 is connected to an external negative pressure pump. A plurality of extraction holes 21 are opened on the surface of the support block 1801, and the extraction holes 21 and the connecting tube 20 are connected.

[0042] The technical effect achieved by the above embodiment is: the human tissue fluid at the supporting position of the supporting sleeve 2 can be extracted by using the extraction hole 21 to avoid being retained outside the styloid process and affecting the surgical field of view.
