Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a diffuse optical fiber that is easy to position. Background Art

[0002] Diffuse optical fibers are commonly used in medical devices that combine photosensitizing drugs for tumor treatment. These fibers consist of a quartz fiber connected to the end of a transmission fiber. The quartz fiber scatters the laser light transmitted from the transmission fiber. The scattered laser light then strikes the photosensitizing drug, stimulating it to produce its therapeutic effect and ultimately achieving the desired tumor treatment. Currently, there are two main types of diffuse optical fibers: rod-shaped (column-shaped) and point-shaped.

[0003] For example, the patent document with application number 201810381285.6 discloses a diffuse optical fiber that is easy to position. This invention discloses a diffuse optical fiber that is easy to position, which relates to the field of medical device technology and solves the problem of inaccurate positioning of longer scattering ends. The diffuse optical fiber that is easy to position includes a transmission optical fiber and a scattering end located at the front end of the transmission optical fiber. The scattering end is provided with three positioning rings, two of which are located at the two ends of the scattering end, and the other is located in the middle of the scattering end. The present invention provides three positioning rings on the scattering end. The positional relationship of the three positioning rings is used to infer the approximate position of the scattering end to achieve the positioning of the scattering end. The invention is particularly suitable for positioning scattering ends with longer lengths. However, when the transmission optical fiber with the positioning ring is delivered into the patient's body, the diffuse optical fiber that is easy to position has no guiding device, which increases the time to find the tumor location and causes discomfort to the patient.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a diffuse optical fiber that is easy to position is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a diffuse optical fiber that is easy to position, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a diffuse optical fiber that is easy to position, including a transmission optical fiber, the front end of the transmission optical fiber is provided with a flexible sleeve, and the front end of the flexible sleeve is provided with a spherical positioning head, and the front and rear ends of the spherical positioning head are set as planes, the surface of the spherical positioning head is provided with a positioning quartz optical fiber, and the front end of the spherical positioning head is provided with a light-transmitting groove, a connector is inserted and installed inside the light-transmitting groove, and a laser connector is provided at the front end of the connector.

[0007] Preferably, a left connecting ring is provided on the left side of the surface of the flexible sleeve, and plug-in blocks are provided at the four corners of the surface of the left connecting ring.

[0008] Preferably, a right connecting ring is provided in front of the left connecting ring, and slots are provided at the four corners of the surface of the right connecting ring.

[0012] 1. The utility model comprises a transmission optical fiber, a flexible sleeve, a spherical positioning head, a light-transmitting groove, a positioning quartz optical fiber, a connector, and a laser connector. The spherical positioning head allows the transmission optical fiber to enter the patient's body more smoothly, facilitating treatment of the patient.

[0013] 2. The utility model is provided with a left connecting ring, a right connecting ring, an insert block, a slot and a magnetic block. When the patient's diseased area is deep, the right connecting ring and the left connecting ring can be quickly merged through the slot and the insert block, and then fixed by the magnetic block, which is convenient for positioning the transmission optical fiber.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 2 As shown, a diffuse optical fiber that is easy to position includes a transmission optical fiber 1, a flexible sleeve 101 is provided at the front end of the transmission optical fiber 1, and a spherical positioning head 2 is provided at the front end of the flexible sleeve 101, and the front and rear ends of the spherical positioning head 2 are set as planes. The advantage of this setting is that through the setting of the spherical positioning head 2, the transmission optical fiber 1 can enter the patient's body more smoothly, making it convenient to treat the patient.

[0020] Furthermore, a positioning quartz optical fiber 202 is provided on the surface of the spherical positioning head 2, and a light-transmitting groove 201 is provided at the front end of the spherical positioning head 2. The advantage of this setting is that the light of the transmission optical fiber 1 can be scattered by the setting of the light-transmitting groove 201, and the laser connector 204 can be assisted to work by the setting of the positioning quartz optical fiber 202.

[0021] Furthermore, a connector 203 is installed inside the light-transmitting groove 201, and a laser connector 204 is provided at the front end of the connector 203. The advantage of this setting is that the diffused light can be focused through the setting of the laser connector 204, and precise irradiation or diffuse irradiation treatment can be selected according to the patient's condition.

[0022] like Figure 3 As shown, a left connecting ring 3 is provided on the left side of the surface of the flexible sleeve 101, and plug-in blocks 302 are provided at the four corners of the surface of the left connecting ring 3, a right connecting ring 301 is provided in front of the left connecting ring 3, and slots 303 are provided at the four corners of the surface of the right connecting ring 301, the plug-in connection between the plug-in block 302 and the slot 303 is plug-in, and a magnetic block 304 is provided on the surface of the right connecting ring 301. The advantage of this arrangement is that the right connecting ring 301 and the left connecting ring 3 can be quickly merged through the slot 303 and the plug-in block 302, and then fixed by the magnetic block 304, which is convenient for positioning the transmission optical fiber 1. When the patient's diseased area is shallow, the right connecting ring 301 and the left connecting ring 3 can be quickly separated, reducing the time for replacing the transmission optical fiber 1.

[0023] Furthermore, the left connecting ring 3 and the right connecting ring 301 are magnetically connected through a magnetic block 304, and the left connecting ring 3 and the right connecting ring 301 are columnar after being combined. The advantage of this setting is that the position of the transmission optical fiber 1 can be found more accurately through the columnar connecting ring.

[0024] Working Principle: When using this easily positioned diffuse fiber, first, if the patient's lesion is deep, the right connecting ring 301 and the left connecting ring 3 are quickly combined through the slot 303 and the insert block 302, and then fixed with the magnetic block 304, making it easier to position the transmission fiber 1. If the patient's lesion is shallow, the right connecting ring 301 and the left connecting ring 3 can be quickly separated, reducing the time required to replace the transmission fiber 1. When treating the patient, the laser connector 204 with the spherical positioning head 2 is inserted into the patient's body to irradiate the patient's area, activating the drug to treat the tumor. This is the working principle of this easily positioned diffuse fiber.
