Problems solved by technology

However, since it is directly implanted into the human body, and it is a radioactive source, the indications must be strictly controlled. In the prior art, the particle implantation operation depends entirely on the doctor’s clinical experience. Although there is a simple particle implantation template as a guide, if you want to Achieving accurate and regular puncture needle implantation may require doctors with 20 to 30 years of clinical experience. For doctors with only a few years of clinical experience, it is difficult to achieve accurate puncture needle puncture. The puncture operation experience of puncture needle needs to be accumulated for a long time. It is difficult to grow rapidly, which is not conducive to the development of the industry

Embodiment 1

[0039] Such as Figure 1 to Figure 5 As shown, a puncture navigation system proposed by the present invention includes

[0040] The adjusting arm 32 used to realize three-dimensional direction movement is provided with a fine-tuning device 33 on the adjusting arm 32, and the fine-tuning device 33 includes an axle sleeve 34 arranged on the adjusting arm 32, and a vertical rotating rod 35 is provided for rotation in the axle sleeve one 34 , the vertical rotating rod 35 is provided with a shaft sleeve 2 36, the shaft sleeve 2 36 is provided with a horizontal rotating rod 37, the end of the horizontal rotating rod 37 is provided with a pin shaft 38, and the pin shaft 38 is provided with a puncture needle clamping device 39,

[0041]The puncture needle clamping device 39 includes a rotating member 391 rotatably arranged on the pin shaft 38. The rotating member 391 is semicircular or fan-shaped, and a vertical needle-holding hole 392 is arranged on it.

[0042] Further, the rotati...

Embodiment 2

[0045] Including all the structures of Embodiment 1, the needle-holding hole 392 is surrounded by two semi-circular rings 3921 hinged to each other, one of which is arranged on the rotating part 391, and also includes a fastening part to connect the two semi-circular rings 3921 buckles.

[0046] In this embodiment, the needle-holding hole 392 is surrounded by two semi-circular rings 3921, so it is more convenient to practice puncture implantation, the puncture needle clamping device 39 is removed from the puncture needle, and the two semi-circular rings 3921 is fastened by fastening parts, and the deviation of the puncture angle will not be caused by misoperation during the practical process.

Embodiment 3

[0048] Including all the structures of Example 1, the needle-holding hole 392 is surrounded by an arc-shaped piece 3922 and an arc-shaped plate 3923. An arc-shaped groove 3924 is provided on the side of the arc-shaped piece 3922 close to its inner wall, and the arc-shaped plate 3923 is slidably arranged on the Inside the arc groove 3924.

[0049] In this embodiment, the needle-holding hole 392 is surrounded by an arc-shaped piece 3922 and an arc-shaped plate 3923. After the arc-shaped plate 3923 rotates, the arc-shaped piece 3922 can be opened or closed. The arc-shaped plate 3923 is arranged on the arc of the arc-shaped piece 3922. In the shaped groove 3924, it can be operated very conveniently, and the insertion of the puncture needle and the removal of the puncture needle holding device 39 after puncturing to the patient are well realized.

Abstract

The invention belongs to the technical field of particle puncture, and provides a puncture navigation system. The puncture navigation system comprises an adjusting arm for achieving movement in the three-dimensional direction; a fine-adjusting device is arranged on the adjusting arm and comprises a first shaft sleeve arranged on the adjusting arm; a vertical rotating rod is rotatably arranged in the first shaft sleeve; a second shaft sleeve is arranged on the vertical rotating rod; a transverse rotating rod is arranged in the second shaft sleeve; a pin shaft is arranged at the end of the transverse rotating rod; a puncture needle clamping device is arranged on the pin shaft and comprises a rotating piece rotatably arranged on the pin shaft, the rotating piece is in a semicircular shape ora fan shape, and a vertical needle holding hole is formed in the rotating piece; and angular scale lines are arranged on the rotating piece, and pointers for indicating the rotating piece to rotate byangles are arranged on the transverse rotating rod. The technical problem that in the prior art, precision and regularity of puncture operation of a puncture needle are difficult to achieve is solved.

Description

technical field [0001] The invention belongs to the technical field of particle puncture, and relates to a puncture navigation system. Background technique [0002] Particle puncture is also called particle implantation. The full name of particle implantation is "radioactive particle implantation treatment technology". It is a treatment method that implants radioactive sources into the tumor to destroy the tumor. The particle implant therapy technique involves a radioactive source, the core of which is radiating particles. However, since it is directly implanted into the human body, and it is a radioactive source, the indications must be strictly controlled. In the prior art, the particle implantation operation depends entirely on the doctor’s clinical experience. Although there is a simple particle implantation template as a guide, if you want to Achieving accurate and regular puncture needle implantation may require doctors with 20 to 30 years of clinical experience. For ...
