Problems solved by technology

If coupled with the poor hand feeling of the anesthesiologist at that time, it is difficult for the doctor to feel and judge, and the dura mater may be punctured, resulting in the failure of the operation, causing the patient to have sequelae such as headache after the operation

Embodiment 1

[0019] Example 1: Injection Set Using Optical Detection of Tissue Patterns

[0020] In the injection set of the present invention, the female needle adopts a general needle head, which is a hollow design, and the sub-needle of the present invention can be placed in it and fit together, and the tip of the female needle can penetrate into such as skin, muscle, fat or mucous membrane, Ligamentum flavum and other biological tissues. The sub-needle is also a hollow design, but the fiber bundle is placed in the center of the sub-needle, and the optical glue is used to glue the optical fiber and the sub-needle on the sub-needle. Then it is connected to the light source, light detector and necessary control circuit.

[0021] figure 2 It is a schematic diagram of the detection method of the present invention. In the figure, the light emitted by the light source 210 is introduced into the optical fiber in the sub-needle 270 by the lenses 220, 230 or an appropriate optical device, and...

[0022] Embodiment 2: Utilize pig to carry out puncture test

[0023] In the pilot study (prospective study), other people are used to experiment with piglets and the relevant tissues are removed after slaughtering the piglets, so as to figure 2 The reflectance spectra of different tissues were obtained in a different way. The light source in the figure is a xenon lamp, and the lens guides the light source into the objective lens of a microscope to focus the light into a small spot and then guides it into one arm of a Y-shaped fiber bundle. The fiber optics of this fiber optic bundle are arranged as shown in the lower right figure: the central light-colored one bundle 270 is the incident light path, and the surrounding dark-colored six bundles 280 are the reflected light paths from the tissue, which come out from the other arm of the Y-shaped fiber and enter a spectrometer . The spectrometer feeds this tissue reflection spectrum into a computer. image 3 It is the result ob...

[0025] Embodiment 3: Design of photodetector

[0026] Figure 4 It is to use the above conclusions as a detection system integrating photoelectric components to achieve our goal.

[0027] Figure 4The control circuit 420 in the control circuit can control two groups of lasers, taking 650nm and 532nm as examples as modulation pulse outputs with opposite phases, that is, when the 650nm laser light source 431 is turned on, the 532nm laser light source 441 is turned off. (OFF State), and vice versa. The two groups of laser beams pass through the optical path 430 and the optical path 440 and are divided into two optical paths 450 and 460 after passing through the beam splitter 435 . On the optical path 450, the light enters the optical fiber 451 through the lens or an equivalent optical component 437 and is guided into the tissue. After being reflected, the light returns along the original path to the lens or an equivalent optical component 437, and the beam splitter 436 is refl...

Abstract

The invention provides a method for locating an injection kit, which comprises the following steps: injecting a drawer-type sub-needle containing optical fiber in a hollow mother needle so as to form a puncture kit; connecting the optical fiber with light source and a detector used for detecting the optical property of an individual organization, wherein a light detector is capable of detecting the optical property of the individual organization so as to provide the information of organization form; and inserting the puncture kit into an individual, and judging the position where the tip end of the puncture kit reaches through the organization form information provided by the light detector. According to the invention, an injection catheter can be precisely placed on a special position in a tested people body; the precision of a surgery or an anesthesia surgery is improved; and the surgical risk of a patient is lowered.

Description

technical field [0001] The invention relates to a positioning method for an injection set, which is applied to clinical operations such as minimally invasive surgery, spinal epidural anesthesia, and tissue identification, such as postoperative pain relief or painless childbirth, and identification of intestinal adhesions in abdominal surgery. Distinguish between tumor and normal tissue, etc. Background technique [0002] At present, it is mostly necessary to rely on the experience and technology of anesthesiologists to judge whether the puncture needle has reached the epidural space. Anesthesiologists use their hands to feel or feel the resistance of the ligamentum flavum as the first important indicator. The resistance of the yellow ligament varies with age, gender, and body shape. For example, the elasticity of the yellow ligament of the elderly is poor. Pregnant women or obese people who do not exercise regularly may also have less resistance from the ligamentum flavum ...
