[0002] The hemorrhoid ligation device is a medical device used for minimally invasive hemorrhoid surgery. It is mainly suitable for the treatment of internal hemorrhoids and mixed hemorrhoids. The ligation device is used to put a special rubber ring or elastic line on the base of the hemorrhoidal tissue or the mucosa above the hemorrhoid. The tightening of the rubber ring or the pulling effect of the elastic line can block the blood supply of the hemorrhoids or reduce venous reflux, causing the hemorrhoidal tissue to be ischemic, atrophic, and necrotic, and then gradually fall off, and the wound tissue is repaired and healed. Adding a lighting system to the traditional hemorrhoid ligation device can make the surgical field clearer, the operation more precise, effectively eliminate the blind spot of treatment, and avoid the occurrence of mis-ligation, thereby improving the safety and effect of the operation.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-6A hemorrhoid ligation device with a light source comprises a hemorrhoid ligation device body 1, a barrel assembly 2 is installed on the hemorrhoid ligation device body 1, a gun head assembly 3 is arranged at the front end of the barrel assembly 2, an insertion cavity 5 is downwardly opened at the top of the gun head assembly 3, and a glass cover 4 is arranged at the front end of the gun head assembly 3; an installation cavity 51 is opened inside the gun head assembly 3 below the insertion cavity 5, a installation block 7 is movably arranged in the installation cavity 51, and a lamp bead body 6 is installed in front of the installation block 7.

[0022] The insertion cavity 5 is connected to the installation cavity 51, and the insertion cavity 5 is adapted to be opened by the lamp bead body 6. The lamp bead body 6 passes through the insertion cavity 5 and enters the interior of the installation cavity 51, so that the lamp bead body 6 can be installed.

[0023] There are multiple springs 8 arranged forward on the rear wall of the installation cavity 51, and the other ends of the springs 8 are connected to the installation block 7. The installation block 7 can be moved forward in the installation cavity 51 by the arrangement of the springs 8. It is worth noting that when the springs 8 are in a normal state, the installation block 7 extended by the springs 8 is located below the insertion cavity 5.

[0024] The top of the mounting block 7 is set as an inclined surface, and the inclined surface is inclined toward the front of the mounting cavity 51. By setting the inclined surface on the top of the mounting block 7, when the lamp bead body 6 enters the mounting cavity 51 from the insertion cavity 5, the bottom of the lamp bead body 6 contacts the inclined surface on the top of the mounting block 7, so that the mounting block 7 can be pressed backwards, so that the mounting block 7 moves backwards, so that the lamp bead body 6 can smoothly enter the mounting cavity 51 and be located in front of the mounting block 7.

[0025] Among them, a connector 61 is arranged upwardly at the rear of the top of the lamp bead body 6, and a plurality of adjustment cavities 52 are adapted to be opened in front of the insertion cavity 5 corresponding to the connector 61. When the lamp bead body 6 is located in the installation cavity 51 and moves forward, both ends of the connector 61 above it enter the adjustment cavity 52. ​​When the user needs to remove the lamp bead body 6, he only needs to push the connector 61 above the adjustment cavity 52 backward and then pull it out.

[0026] The lamp bead body 6 enters the installation cavity 51 from the insertion cavity 5, and when the installation block 7 is clamped on the lamp bead body 6, the connecting piece 61 extends out from the adjustment cavity 52, and the light source end of the lamp bead body 6 is located behind the glass cover 4. The glass cover 4 can protect the lamp bead body 6.

[0027] In the present utility model, a barrel assembly 2 is installed on the hemorrhoid ligation device body 1, a gun head assembly 3 is arranged at the front end of the barrel assembly 2, an insertion cavity 5 is opened downward at the top of the gun head assembly 3, and a glass cover 4 is arranged at the front end of the gun head assembly 3. An installation cavity 51 is opened inside the gun head assembly 3 below the insertion cavity 5, a mounting block 7 is movably arranged in the mounting cavity 51, and a lamp bead body 6 is installed in front of the mounting block 7. It is worth noting that the specific structures and usage methods of the hemorrhoid ligation device body 1, the barrel assembly 2 and the gun head assembly 3 are all prior arts, and do not belong to the main technical features of the present technical solution, so they are not elaborated.

[0028] Furthermore, when the user needs to install the lamp bead body 6, the lamp bead body 6 can be directly inserted from the insertion cavity 5 into the installation cavity 51. When the lamp bead body 6 enters the installation cavity 1, the bottom of the lamp bead body 6 contacts the inclined surface at the top of the mounting block 7, so that the mounting block 7 moves backward, so that the lamp bead body 6 can enter the installation cavity 51 and be located in front of the mounting block 7. Then the mounting block 7 moves forward by the elastic force of the spring 8, so that the lamp bead body 6 can be moved forward by the mounting block 7, so that the installation of the lamp bead body 6 can be completed. And in the process of the lamp bead body 6 moving forward, both ends of the connecting piece 61 above it enter the adjustment cavity 52.

[0029] Furthermore, when the user needs to remove the lamp bead body 6, the connecting piece 61 can be buckled backwards, and the connecting piece 61 can drive the lamp bead body 6 to move backwards. When the lamp bead body 6 moves to the bottom of the insertion cavity 5, the lamp bead body 6 can be lifted by the connecting piece 61, thereby completing the removal of the lamp bead body 6. In this way, the lamp bead body 6 and various components on the hemorrhoid ligation device body 1 can be disinfected.

[0030] In the utility model, the lamp bead body 6 enters the installation cavity 51 from the insertion cavity 5. The installation of the lamp bead body 6 can be achieved through the setting of the installation block 7 and the spring 8. The lamp bead body 6 can be quickly removed by adjusting the setting of the cavity 52 and the connecting piece 61, so that the user can remove the various components on the hemorrhoid ligation device body 1 and the lamp bead body 6 for disinfection.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
