Embodiment 1
[0035] Such as figure 1 with 2 As shown, a surgical auxiliary positioner is composed of an outer compression body 1 and an inner positioning body 2. The compression body 1 is made of a swelling material and has a small volume before contact with liquid, covering the positioning body 2. , injected into the vicinity of the tumor by a hollow needle.
[0036] After the compression body 1 contacts the body fluid, the swelling material absorbs the body fluid and expands, and the volume increases, such as figure 2 As shown; How long does it take to swell when in contact with body fluids, and how much the volume swells, you can choose according to the different swelling materials and the needs of the operation; generally set it to swell 5 to 10 times after contacting with body fluids for 5 seconds to 30 minutes, which meets the needs of surgery That's it.
[0037] The swelling material is one or more of polyacrylic acid, sodium polyacrylate, polyvinyl alcohol, sodium alginate, aga...
Embodiment 2
[0044] image 3 Compared with the embodiment 1, the surgical auxiliary locator shown has a shell 3 covered outside the compression body 1, and the shell 3 will be ablated after being in contact with body fluid for 5-10 minutes. Preferably, a tracer is included in the housing that is released into surrounding tissue upon ablation of the housing for marking the tissue location. For example, nuclides, methylene blues, and nanocarbons. For example, after the nuclide-labeled tracer is injected into the human body, the positron annihilation generated during the decay of the nuclide can be imaged through electronic detection and computer reconstruction, so that we can obtain human metabolism or functional images.
[0045] A layer of shell 3 is arranged outside the compression body 1 to suspend the expansion of the compression body 1; the compression body 1 can only be expanded when the shell 3 is ablated to the point where the compression body 1 cannot be restricted.
[0046] The s...
Embodiment 3
[0052] Such as Figure 4 Compared with the product in Example 1, the surgical auxiliary locator shown has the compression body 1 and the positioning body 2 as an integrated structure, which is equivalent to the expansion function of the positioning body 2, or the positioning function of the compression body 1, such as after compression wire ball.
[0053] The tiny compressed metal wire ball is injected near the tumor through a hollow needle, and immediately expands to form an expanded locator; a shell 3 can also be added outside the compressed body 1, Figure 4 As shown, after the shell 3 is ablated to a certain extent after injection, the metal silk ball expands. Preferably, a tracer is included in the housing that is released into surrounding tissue upon ablation of the housing for marking the tissue location. For example, nuclides, methylene blues, and nanocarbons. For example, after the nuclide-labeled tracer is injected into the human body, the positron annihilation ge...
