Description

Technical Field

[0001] The utility model relates to the field of medical detection equipment, in particular to a multi-channel endoscope LED cold light source. Background Technique

[0002] Currently, endoscopes on the market generally need an externally connected cold light source for illumination. Usually, an optical fiber bundle is used to guide the light emitted by an external light source (such as a xenon lamp cold light source, a halogen lamp cold light source, and an LED cold light source, etc.) into the internal optical fiber bundle of the endoscope through the endoscope or the illumination beam interface part. In recent years, with the rapid development of LED light sources, many endoscopes use LED light sources as the cold light source of the endoscope. In the prior art, only the LED light source is used to replace the previous xenon lamp and halogen lamp light source bulbs.

[0003] However, the light intensity of the LED light source is relatively low. At the same time, the LED light source is generally installed on the periphery of the endoscope lens, and the light of the LED light source is generally emitted towards the endoscope lens. As a result, the brightness on both sides and the rear end of the endoscope lens will decrease, making it impossible for the endoscope lens to clearly capture the two sides of the endoscope lens. Therefore, a multi-channel endoscope LED cold light source is needed to supplement the light intensity on both sides of the endoscope lens. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-channel endoscope LED cold light source that can enhance the illumination intensity of the LED light source.

[0005] The technical solution to achieve the above purpose is: a multi-channel endoscope LED cold light source, including a control box. A connecting pipe is connected to the side wall of the control box. The connecting pipe is wrapped with a medical rubber sleeve. One end of the connecting pipe away from the control box is connected to an endoscope main body. One end of the endoscope main body is connected to a lens. A first LED cold light source is connected to the side wall of the lens. A retaining ring is connected to the side wall of the lens. The first LED cold light source is located outside the retaining ring. A placement groove is provided on the side wall of the endoscope main body. A second LED cold light source is connected to one end of the placement groove close to the lens. A placement block is connected to the other end of the placement groove away from the lens. A reflecting mirror is connected to the side wall of the placement block. A protective member is provided on the endoscope main body.

[0006] Preferably, the thickness of the retaining ring is greater than the thickness of the first LED cold light source.

[0007] Preferably, the shape of the placement block is frustum-shaped, and the reflecting mirror is located on the inclined side wall of the placement block.

[0008] Preferably, the protective member includes a housing, a glass tube, a fixed block, a screw, a sealing cap, a nut, and a limiting member. Two symmetrically distributed housings are sleeved on the side wall of the endoscope body. A glass tube is embedded and connected to the middle of the side wall of the housing. Two symmetrically distributed fixed blocks are connected to the side wall of the housing. A screw is movably placed on the side wall of the fixed block. Sealing caps are connected to both ends of the screw. A nut is threadedly connected to the side wall of the screw.

[0009] Preferably, the inner wall of the glass tube communicates with the inside of the housing.

[0010] Preferably, both ends of the housing are provided with rounded corners.

[0011] Preferably, the housing is in the shape of a semi-cylindrical tube, and the inner diameter of the port of the housing is smaller than that of the connecting tube.

[0012] Preferably, the limiting member includes a limiting block, a through hole, and a top cover. A through hole is provided at one end of the housing away from the lens. The top cover is connected to the top end of the through hole. Two symmetrically distributed limiting blocks are connected to the side wall of the connecting tube.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1) The first LED cold light source can irradiate along the direction of the lens, so as to ensure the light in front of the lens. There is a retaining ring connected to the side wall of the lens. The first LED cold light source is located outside the retaining ring. The thickness of the retaining ring is greater than that of the first LED cold light source, so as to avoid the direct light of the first LED cold light source shining on the lens, resulting in the lens being unable to clearly see the patient's diseased part due to excessive light intensity. The light emitted by the second LED cold light source is reflected by the reflector. The reflector is located on the inclined side wall of the placement block, so that the light emitted by the second LED cold light source can be reflected to both sides of the lens, thereby increasing the light intensity on both sides of the lens, and further enabling the lens to take clearer pictures of both sides of the lens.

[0015] 2) Combine the two housings together to form a complete circular tube. Pass the screw through the fixed block, thread the nut on the side wall of the screw, and fix the sealing caps at both ends of the screw to prevent the screw from detaching from the fixed block. At this time, align the glass tube with the placement groove, press one of the sealing caps against the fixed block, and turn the nut to firmly fix the two housings together, thereby preventing the placement groove from scratching or pulling the patient's body tissue. At the same time, place the limiting block in the through hole. Due to the obstruction of the limiting block to the top cover, the housing is prevented from detaching from the lens.

The connecting pipe 2 is wrapped with a medical rubber sleeve. The end of the connecting pipe 2 away from the control box 1 is connected to an endoscope body 3. One end of the endoscope body 3 is connected to a lens 4. A first LED cold light source 6 is connected to the side wall of the lens 4. A retaining ring 5 is connected to the side wall of the lens 4. The first LED cold light source 6 is located outside the retaining ring 5. The thickness of the retaining ring 5 is greater than the thickness of the first LED cold light source 6. A placement groove 7 is provided on the side wall of the endoscope body 3. A second LED cold light source 8 is connected to the end of the placement groove 7 close to the lens 4. A placement block 9 is connected to the end of the placement groove 7 away from the lens 4. The shape of the placement block 9 is frustum-shaped.

The reflecting mirror 19 is inclined towards the lens 4. A protective member is provided on the endoscope body 3.

[0030] The control box 1 is used to turn on the first LED cold light source 6 and the second LED cold light source 8. The first LED cold light source 6 can irradiate along the lens 4 to ensure the light in front of the lens 4. Since the retaining ring 5 is connected to the side wall of the lens 4 and the first LED cold light source 6 is located outside the retaining ring 5, and the thickness of the retaining ring 5 is greater than the thickness of the first LED cold light source 6, it is avoided that the light of the first LED cold light source 6 directly irradiates the lens 4, resulting in the lens 4 being unable to clearly see the patient's diseased part due to excessive light intensity. The light emitted by the second LED cold light source 8 is reflected by the reflecting mirror 19. Since the reflecting mirror 19 is located on the inclined side wall of the placement block 9, the light emitted by the second LED cold light source 8 can be reflected to both sides of the lens 4, thereby increasing the light intensity on both sides of the lens 4, and further enabling the lens 4 to take clearer pictures of both sides of the lens 4.

The lengths of the limiting block 16 and the through hole 17 are both greater than the maximum length that the nut 15 can move.

[0032] Combine two outer shells 10 together to form a complete circular tube. Pass the screw 13 through the fixed block 12, thread the nut 15 onto the side wall of the screw 13, and fix the caps 14 at both ends of the screw 13 to prevent the screw 13 from detaching from the fixed block 12. At this time, align the glass tube 11 with the placement groove 7, press one of the caps 14 against the fixed block 12, and turn the nut 15 to firmly fix the two outer shells 10 together, thereby preventing the placement groove 7 from scratching or pulling the patient's body tissue. At the same time, place the limit block 16 in the through hole 17. By using the obstruction of the limit block 16 to the top cover 18, the outer shell 10 is prevented from detaching from the lens 4.
