Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical application technology, and in particular to an isolation sleeve for a Raman spectroscopy fiber optic probe. Background Technology
[0002] Raman spectroscopy, as an important tool for analyzing the biochemical composition of biological tissues, has been widely applied in the medical field, with its ability to perform in vivo detection using Raman spectroscopy probes being particularly prominent. These probes typically employ fiber optic designs, enabling precise transmission of a laser beam to the target tissue within the patient's body and efficient collection of the returned scattered light signals, thereby revealing the tissue's biochemical information. The advantage of in vivo detection methods lies in their ability to acquire real-time biochemical information of tissues during surgery, helping physicians make more timely decisions during the procedure.
[0003] Despite the immense potential of Raman spectroscopy in medical applications, its practical promotion and application still face multiple challenges. First, the high manufacturing and procurement costs are the primary factor limiting its widespread clinical application, especially in surgical settings where frequent probe replacements significantly increase costs. Furthermore, the use of Raman spectroscopy probes among multiple patients may pose a risk of cross-infection, particularly when inadequate sterilization or when probes cannot be used disposable, directly limiting their scope and frequency of use. Moreover, the difficulty in maintaining a consistent probe working distance during in vivo detection is a critical factor affecting data acquisition accuracy; even small fluctuations in working distance can introduce significant errors, impacting the resolution of Raman spectroscopy data and consequently the reliability of diagnostic results. Therefore, traditional Raman spectroscopy probes still face a series of problems that need to be addressed in practical applications. Utility Model Content
[0004] The purpose of this invention is to address the problems of cross-infection, inaccurate data collection, and high cost associated with traditional Raman spectroscopy probes by providing an isolation sleeve for a Raman spectroscopy fiber optic probe. This sleeve offers advantages such as preventing direct contact between the probe and the target tissue, reducing the risk of infection and operating costs, and ensuring the accuracy of data collection by setting a working gap.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An isolation sleeve for a Raman spectroscopy fiber optic probe includes a sleeve body, in which a spectral probe is placed. The spectral probe includes a laser needle tip and a fiber optic needle tail. A light-transmitting front plug is provided at one end of the sleeve body near the laser needle tip. The light-transmitting front plug includes a light-transmitting glass plate, and a working gap is provided between the light-transmitting glass plate and the laser needle tip.
[0007] Preferably, the light-transmitting front plug is detachably installed at the end of the sleeve body, and the light-transmitting front plug also includes a tube body, with the light-transmitting glass slide installed inside the tube body.
[0008] Preferably, the end of the sleeve body is provided with a threaded joint, and the end of the tube body away from the light-transmitting glass is provided with a threaded groove, and the tube body is movably connected to the threaded joint through the threaded groove.
[0009] Preferably, the inner wall of the tube is provided with a mounting slot, and the light-transmitting glass sheet is fixed on the mounting slot.
[0010] Preferably, the transparent glass slide is a quartz glass slide.
[0011] Preferably, a back plug is movably installed at one end of the sleeve body near the end of the optical fiber needle tail, and a through hole matching the optical fiber needle tail is formed on the back plug.
[0012] Preferably, the sleeve body has a tapered tail at one end near the fiber optic needle tail, and the rear plug includes a cover plate that matches the tapered tail and a tapered rubber plug, with the tapered rubber plug inserted into the gap between the tapered tail and the fiber optic needle tail.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By setting a light-transmitting front plug at the end of the sleeve body, the laser of the laser needle can pass through the light-transmitting front plug. The presence of the sleeve body prevents the spectral probe from directly contacting the target tissue during operation, reducing the risk of infection. Furthermore, a working gap is set between the light-transmitting glass slide of the light-transmitting front plug and the laser needle of the spectral probe, ensuring that the distance between the laser probe and the target tissue remains constant when the light-transmitting front plug is in contact with the target tissue, thus guaranteeing the accuracy of data acquisition.
[0015] 2. By designing the light-transmitting front stop as a detachable structure, the distance between the light-transmitting glass slide and the laser needle tip can be changed by replacing the front stop with different lengths, thereby adjusting the working gap size to adapt to Raman spectroscopy detection of different tissues. Furthermore, the use of quartz glass slides effectively avoids fluorescence contamination caused by glass and other materials.
[0016] 3. By setting a rear plug on the sleeve body, the spectral probe is tightly fixed inside the sleeve body, preventing the spectral probe working chamber from shaking. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1-3 As shown, an isolation sleeve for a Raman spectroscopy fiber optic probe includes a sleeve body 2, within which a spectral probe 1 is placed. The spectral probe 1 includes a laser needle tip and a fiber optic needle tail. A light-transmitting front plug 4 is provided at the end of the sleeve body 2 near the laser needle tip. The light-transmitting front plug 4 includes a light-transmitting glass slide 7, and a working gap is provided between the light-transmitting glass slide 7 and the laser needle tip. Each time the spectral probe 1 is used, it is inserted into a new sleeve body 2, and human tissue detection is performed through the sleeve body 2. This avoids direct contact between the spectral probe 1 and the human body, reducing the risk of cross-infection. The sleeve body 2 is a disposable consumable and does not require cleaning or disinfection, reducing the workload of using the spectral probe 1. When the sleeve body 2 is in use, because it is equipped with a light-transmitting front plug 4 at its end, the laser emitted by the laser needle can be received by the target tissue through the light-transmitting glass plate 7, and the scattered laser signal can also be collected by the laser needle through the light-transmitting glass plate 7. There is a working gap between the light-transmitting glass plate 7 and the laser needle. During operation, the light-transmitting glass plate 7 is in contact with the target tissue. Due to the existence of the working gap, the distance between the end of the laser needle and the target tissue is the length of the working gap. When performing laser detection at multiple positions, there is always a working gap between the laser needle and the target tissue. In this way, the data collection at each position is less prone to error. Moreover, the laser probe needs to have both laser emission and reception capabilities, and the existence of the working gap can also ensure that the scattered laser energy signal is received by the end of the laser needle.
[0025] like Figure 3As shown, the light-transmitting front plug 4 is detachably installed at the end of the sleeve body 2. The light-transmitting front plug 4 also includes a tube body 8, and the light-transmitting glass slide 7 is installed inside the tube body 8. The light-transmitting front plug 4 is connected to the sleeve body 2 in a detachable installation manner. The length of the tube body 8 of the light-transmitting front plug 4 determines the size of the working gap between the light-transmitting glass slide 7 and the laser needle. This design allows for the replacement of light-transmitting front plugs 4 with different tube body 8 lengths. When different working distances between the laser needle and the target tissue are required, a suitable specification of light-transmitting front plug 4 can be selected for use, ensuring the flexibility of the detection.
[0026] The above-mentioned light-transmitting front plug 4 adopts a detachable connection method, such as... Figure 3 and Figure 4 As shown, a threaded connector 6 is provided at the end of the sleeve body 2, and a threaded groove is provided at the end of the tube body 8 away from the light-transmitting glass slide 7. The tube body 8 is movably connected to the threaded connector 6 through the threaded groove. Here, the threaded installation method is chosen to achieve the removability of the light-transmitting front plug 4, which is simple in structure and less prone to failure during operation. An installation bayonet 9 is provided on the inner wall of the tube body 8, and the light-transmitting glass slide 7 is fixed on the installation bayonet 9. The installation bayonet 9 makes it easier to fix the light-transmitting glass slide 7 inside the tube body 8. The light-transmitting glass slide 7 is generally located at the end of the tube body 8 that contacts the target tissue. The light-transmitting glass slide 7 is a quartz glass slide. In addition to its higher hardness and transparency and longer service life, the quartz glass slide is chosen to effectively avoid the generation of fluorescence infection caused by materials such as glass.
[0027] like Figure 1 As shown, since the spectral probe 1 is inserted inside the sleeve body 2 during use, in order to ensure that the spectral probe 1 does not fall out of the sleeve body 2, a back plug 3 is movably installed at one end of the sleeve body 2 near the fiber optic needle tail. The back plug 3 has a through hole that matches the fiber optic needle tail. The back plug 3 can prevent the spectral probe 1 from falling out of the tail of the sleeve body 2.
[0028] The rear plug 3 seals the tail of the sleeve body 2. However, to facilitate the insertion of the spectral probe 1 into the sleeve body 2, the internal space of the sleeve body 2 is generally slightly larger than the size of the spectral probe 1. Therefore, although the rear plug 3 can prevent the spectral probe 1 from falling out, it cannot guarantee that the spectral probe 1 will not shake inside the sleeve body 2. Shaking can easily damage the spectral probe 1. Figure 5 As shown, a tapered tail 5 is provided at one end of the sleeve body 2 near the fiber optic needle tail. The rear plug 3 includes a cover plate 10 that matches the tapered tail 5 and a tapered rubber plug 11. The tapered rubber plug 11 is inserted into the gap between the tapered tail 5 and the fiber optic needle tail. By pressing the tapered rubber plug 11 into the tapered tail 5, the gap between the tapered tail 5 and the fiber optic needle tail can be filled, thus fixing the area around the fiber optic needle tail and allowing the spectral probe 1 to swing left and right, increasing the stability of the spectral probe 1.
