Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pair of meibomian gland dredging forceps. Background Art

[0002] Meibomian glands are the largest sebaceous glands in the body. They are located near the roots of the eyelashes on the upper and lower eyelids. They protect the tear film formed on the surface of the eyeball by secreting lipids and various proteins, making it difficult for tears to evaporate, thereby keeping the eyes moist. Meibomian glands are special sebaceous glands around the eyelids, located in the tarsal plate. Their main function is to secrete a lipid layer to delay the evaporation of the aqueous layer. In addition, the lipid layer can maintain the surface tension of the tear film to prevent the tears from evaporating too quickly, and can lubricate the contact surface between the eyelids and the eyeball, so that when the eyes are closed, the airtight state between the eyelids and the eyeball can be maintained. There are about 50 meibomian glands in the upper eyelids and about 25 meibomian glands in the lower eyelids.

[0003] When the secretion of eyelid oil of the meibomian gland decreases or the quality deteriorates, resulting in unstable tears, it is necessary to use the meibomian gland unblocking device to unblock the meibomian gland. Generally, during the use of the meibomian gland unblocking device, one side needs to be in contact with the meibomian gland, and the other side needs to be in contact with the skin of the eyelid. Then, by gently squeezing the meibomian gland, the meibum at one end is unblocked toward the opening of the meibomian gland, thereby achieving a therapeutic effect.

[0004] For example, the patent with the authorization announcement number CN215960999U discloses a meibomian gland massage clamp, which includes: two forceps arms and a massage structure, the massage structure is composed of a gasket and a massage head, one end of the two forceps arms is fixedly connected, and the other ends of the two forceps arms are respectively provided with a gasket and a massage head. When the meibomian gland massage clamp is used, one forceps arm is supported on the eyelid by the gasket to remain motionless, and the other forceps arm massages the meibomian gland through the massage head.

[0005] Although the above-mentioned meibomian gland massage clamp can adjust the length of the forceps arm through the positioning structure to meet the needs of different patients. However, when performing meibomian gland massage on the same patient, as the massage head moves on the meibomian gland, the distance between the massage position and the forceps arm with the gasket changes, and the gasket is supported on the eyelid and does not move. The operator needs to use the gasket as a fulcrum to change the angle of the massage head to adapt to the change in massage position. In the process of changing the angle of the massage head, the massage strength of the massage head will change, which requires the medical operator to have rich practical experience. Otherwise, during the actual operation, the meibum may move to the sides and front and back of the inner wall of the meibomian gland due to pressure, resulting in incomplete dredging, affecting the treatment effect, and even causing pain to the patient. Utility Model Content

[0006] The utility model aims to disclose a pair of meibomian gland unclogging forceps to solve the problem that common meibomian gland massage clamps cannot unblock the gland ducts blocked by meibomian fat with quantitative and constant pressure, resulting in pain for patients or insufficient unclogging.

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] A preferred embodiment of the meibomian gland unclogging forceps of the utility model is as follows Figures 1 to 3As shown, the meibomian gland unclogging forceps include a first forceps arm 1, a second forceps arm 2, an assembly seat 3, a return spring 4 and a massage wheel 5. The first forceps arm 1 and the second forceps arm 2 are the main structure of the meibomian gland unclogging forceps. The assembly seat 3, the return spring 4 and the massage wheel 5 are all assembled on the first forceps arm 1, and the assembly seat 3 is used to assemble the massage wheel 5.

[0025] The first tweezer arm 1 has a head end and a tail end, the second tweezer arm 2 has a head end and a tail end, the tail end of the first tweezer arm 1 is fixedly connected to the tail end of the second tweezer arm 2, the head end of the first tweezer arm 1 and the head end of the second tweezer arm 2 are far away from each other, so that there is an angle between the first tweezer arm 1 and the second tweezer arm 2, the first tweezer arm 1 and the second tweezer arm 2 form a V-shaped structure as a whole, and the head end of the first tweezer arm 1 and the head end of the second tweezer arm 2 can approach and move away from each other.

[0026] The head end of the first forceps arm 1 is formed with an assembly cavity 11, and the assembly seat 3 has an inner end and an outer end, the inner end is located inside the assembly cavity 11, and the outer end is located outside the assembly cavity 11. The assembly seat 3 is movably assembled in the assembly cavity 11 along the length direction of the first forceps arm 1, and the assembly seat 3 can move in the assembly cavity 11 along the length direction of the first forceps arm 1 to change the position of the assembly seat 3 and adjust the distance between the massage wheel 5 and the first forceps arm 1. When the position of the massage wheel 5 changes during the massage process, the assembly seat 3 can move in the assembly cavity 11 along the length direction of the first forceps arm 1 to adapt to the change in the distance between the massage wheel 5 and the first forceps arm 1.

[0027] The return spring 4 is assembled in the assembly cavity 11 of the first forceps arm 1, and one end of the return spring 4 is fixedly connected to the inner wall of the assembly cavity 11, and the other end is fixedly connected to the inner end of the assembly seat 3, that is, the return spring 4 is fixedly connected between the inner wall of the assembly cavity 11 and the inner end of the assembly seat 3. When the return spring 4 is compressed or stretched, the return spring 4 applies elastic force to the assembly seat 3, so that the assembly seat 3 can be automatically reset to compensate for the change in the distance between the outer end of the assembly seat 3 and the first forceps arm 1.

[0028] The inner end of the second forceps arm 2 is used to support the eyelid of the patient, and the massage wheel 5 is rotatably mounted on the outer end of the mounting seat 3, and the rotation center line of the massage wheel 5 extends along the width direction of the first forceps arm 1. The massage wheel 5 is used to reciprocate on the meibomian glands so that the meibum of the meibomian glands is discharged from the inside to the outside.

[0029] When massaging the meibomian gland, the head end of the first tweezer arm 1 is supported on the eyelid, and the assembly seat 3 installed at the head end of the second tweezer arm 2 drives the massage wheel 5 to move back and forth on the meibomian gland. The position of the massage wheel 5 changes during the massage. Since the assembly seat 3 is movably installed in the assembly cavity 11, the assembly seat 3 can move along the length direction of the first tweezer arm 1. At the same time, since a reset spring 4 is connected between the inner end of the assembly seat 3 and the inner wall of the assembly cavity 11, the reset spring 4 applies an elastic force to the assembly seat 3, and drives the assembly seat 3 to reset when the massage wheel 5 returns to its original position. When the head end position of the second tweezer arm 2 remains unchanged, the distance between the massage wheel 5 and the second tweezer arm 2 at different massage positions is compensated to ensure that the massage force of the massage wheel 5 remains stable until the meibomian gland meibum is discharged from the inside to the outside, thereby reducing the experience requirements for medical operators and facilitating operation by novices.

[0030] Preferably, the assembly seat 3 includes a guide rod 31 and a mounting plate 32 detachably connected to the guide rod 31, the head end of the first tweezer arm 1 has a guide hole connected to the assembly cavity 11, the guide rod 31 is assembled with the guide hole, and the return spring 4 is fixedly connected to the guide rod 31; the mounting plate 32 is arranged at one end of the guide rod 31 away from the assembly cavity 11, and the massage wheel 5 is rotatably assembled with the mounting plate 32.

[0031] The assembly seat 3 is formed by a guide rod 31 and a mounting plate 32. The end of the guide rod 31 away from the mounting plate 32 forms the inner end of the assembly seat 3, and the end of the mounting plate 32 away from the guide rod 31 forms the outer end of the assembly seat 3. The massage wheel 5 is rotatably assembled with the mounting plate 32, and the guide rod 31 and the mounting rod are detachable. When repair is needed, the mounting plate 32 and the guide rod 31 can be disassembled and assembled to replace parts. In other embodiments, the guide rod 31 and the mounting plate 32 can also be integrally formed.

[0032] In this embodiment, the guide rod 31 is assembled with the guide hole at the head end of the first forceps arm 1, which can limit the moving direction of the assembly seat 3, ensure that the moving direction of the assembly seat 3 is the same as the extension and contraction direction of the reset spring 4, avoid the assembly seat 3 from getting stuck with the first forceps arm 1 during the movement, and ensure that the massage wheel 5 at the outer end of the assembly seat 3 stably squeezes the meibomian glands.

[0033] Preferably, the mounting plate 32 includes a connecting rod 321 and a lug 322. The connecting rod 321 is detachably connected to the guide rod 31. The lug 322 is formed at one end of the connecting rod 321 away from the guide rod 31. There are two groups of lugs 322. The two groups of lugs 322 are arranged at intervals. The massage wheel 5 is rotatably assembled between the two groups of lugs 322.

[0034] The mounting plate 32 is formed by a connecting rod 321 and a lug 322. In this embodiment, the lug 322 is an integral structure with the connecting rod 321. The two groups of lugs 322 form an assembly structure of the massage wheel 5. The lug 322 is formed on the connecting rod 321, which simplifies the assembly form of the massage wheel 5.

[0035] Preferably, a pressure sensor 6 is installed on the inner wall of the assembly cavity 11 , and the reset spring 4 is press-assembled with the pressure sensor 6 . A display 7 is also arranged on the first forceps arm 1 , and the display 7 is connected to the pressure sensor 6 signal to display the elastic pressure value of the reset spring 4 .

[0036] A pressure sensor 6 is mounted on the inner wall of the assembly cavity 11, and the reset spring 4 is pressed against the pressure sensor 6. When the reset spring 4 is compressed, the pressure sensor 6 can detect the magnitude of the elastic force of the reset spring 4 in real time, and then transmit the value of the elastic force to the display 7. The display 7 can display the specific value of the elastic force in real time, so that medical staff can grasp the massage strength of the massage wheel 5 on the meibomian glands in real time, which can prevent the meibum from moving toward the sides and front and back on the inner wall of the meibomian glands, and also increase the comfort of the patient during massage.

[0037] Preferably, the assembly cavity 11 has a cavity opening on the first forceps arm 1 , and the display 7 is arranged to cover the cavity opening.

[0038] The assembly cavity 11 is provided with a cavity opening, which can provide an assembly position for the display 7 and facilitate maintenance of each component through the cavity opening when a failure occurs to the pressure sensor 6 , the display 7 and the electrical circuit.

[0039] Preferably, a friction structure is further included, and surfaces of the first tweezers arm 1 and the second tweezers arm 2 facing away from each other are both provided with the friction structure.

[0040] The friction structure can increase the friction when medical staff hold the device to prevent accidents such as slipping during use.

[0041] Preferably, the friction structure is a friction groove 8 , which extends along the width direction of the first tweezer arm 1 and the second tweezer arm 2 , and a plurality of groups of friction grooves 8 are arranged at intervals along the length direction of the first tweezer arm 1 and the second tweezer arm 2 .

[0042] The friction structure is formed by the friction groove 8, and the friction groove 8 can be formed by conventional processing methods such as rolling, which simplifies the molding method of the friction structure and is easy to use.

[0043] The working process of the utility model is as follows: in normal use, the medical operator supports the head end of the first tweezers arm 1 on the patient's eyelid, and then presses the second tweezers arm 2, so that the massage wheel 5 contacts the meibomian gland and then starts to push. At this time, the second tweezers arm 2 and the massage wheel 5 move simultaneously. When the massage position changes, the reset spring 4 retracts and applies elastic force to the guide rod 31 of the assembly seat 3. The guide rod 31 drives the mounting plate 32 and the massage wheel 5 to move synchronously to compensate for the distance change when the massage position changes, until the meibomian gland meibum is discharged from the inside to the outside. After the above operation is completed, the reset spring 4 is reset and the mounting seat returns to its initial state.

[0044] In summary, the embodiment of the utility model provides a meibomian gland unclogging tweezers, which, when massaging the meibomian glands, the head end of the first tweezer arm is supported on the eyelid, and the assembly seat mounted at the head end of the second tweezer arm drives the massage wheel to move back and forth on the meibomian glands. The position of the massage wheel changes during the massage process. Since the assembly seat is movably assembled in the assembly cavity, the assembly seat can move along the length direction of the first tweezer arm. At the same time, since a reset spring is connected between the inner end of the assembly seat and the inner wall of the assembly cavity, the reset spring applies an elastic force to the assembly seat, and drives the assembly seat to reset when the massage wheel returns to its original position. When the position of the head end of the second tweezer arm remains unchanged, the distance between the massage wheel and the second tweezer arm at different massage positions is compensated to ensure that the massage force of the massage wheel remains stable until the meibomian gland meibum is discharged from the inside to the outside, and the unclogging is more thorough. At the same time, the patient's comfort is improved, and the requirements for the experience of medical operators are reduced, which is convenient for novice operation.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
