[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations, but they are not intended to limit the present invention.

[0023] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical contents.

[0024] like Figure 1 As shown, a preferred embodiment of a fixed bracket for navigation puncture is shown, which includes: a base 1, a catheter adapter 3, a serpentine fixed arm 10, and a fixed bracket 11.

[0025] A plurality of support arms 8 are installed on the outer wall of the base 1, and a reflective ball 9 is installed on the end of each support arm 8 away from the base 1; a bayonet 2 is longitudinally provided on the base 1, and the catheter adapter 3 is clamped in the bayonet 2; one end of the serpentine fixed arm 10 is installed on the base 1, and the other end of the serpentine fixed arm 10 is fixedly installed with a fixed bracket 11.

[0026] During actual use, one end of the serpentine fixing arm 10 is fixed to the base 1, and the other end is fixed to the operating table or headrest through the fixing bracket 11. During the operation, the catheter adapter 3 is placed on the base 1, and the base 1 can fix the catheter adapter 3 so that its position does not change. Then the catheter is placed in the catheter adapter 3. The catheter adapter 3 can be adapted to catheters of different diameters. The device can ensure the accuracy of the puncture direction and improve the treatment effect.

[0027] The present invention also has the following implementation modes based on the above:

[0028] Further, a fixing bracket for navigation puncture, wherein the catheter adapter 3 is two semicircular stop blocks 5, both stop blocks 5 are installed on the bayonet 2, and a catheter fixing hole 7 is formed between the two stop blocks 5. Specifically, the two semicircular stop blocks 5 are installed in the catheter fixing hole 7, and can adapt to multiple catheters of different diameters, and after the catheter position is fixed, the two stop blocks 5 can be taken out of the catheter fixing hole 7 without affecting the catheter position.

[0029] Further, a fixed bracket for navigation puncture, wherein the two limit blocks 5 are fixed to the bayonet 2 through a limiter. Specifically, the two limit blocks 5 are movably fixed in the catheter fixing hole 7 through the limiter.

[0030] Further, a fixing bracket for navigation puncture, wherein a handle 4 is installed on each limit block 5. Specifically, the two limit blocks 5 can be installed into the catheter fixing hole 7 or removed from the catheter fixing hole 7 through the handle 4.

[0031] Further, a fixing bracket for navigation puncture, wherein a fixing bolt 12 is installed at one end of the serpentine fixing arm 10 away from the base 1. Specifically, when the position of the serpentine fixing arm 10 is fixed, the serpentine fixing arm 10 is tightened by the fixing bolt 12, and the fixing bolt 12 is used to tighten or loosen the serpentine fixing arm 10.

[0032] Furthermore, a fixed bracket for navigation puncture, wherein the transverse interface of the bayonet 2 is set in a three-quarter arc. Specifically, the base 1 is provided with a bayonet 2 set in a three-quarter arc, so that the catheter adapter 3 can be taken out from the opening position of the bayonet 2 without being taken out from the top or bottom of the bayonet 2, reducing the movement of the catheter, and can also adapt to the catheter with a special interface at the head end.

[0033] Further, a fixed support for navigation puncture, wherein the fixed support 11 is an elastic clamp. Specifically, the device is clamped on an operating table or a head frame by the elastic clamp.

[0034] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
