Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a multiple implantation device and a multiple implantation method of an implant.
Background
The eye is the most important organ in the human sense, and about 80% of the knowledge in the brain is obtained by the eye. Eyes are used for reading and recognizing words, viewing pictures, viewing figures, enjoying beauty, and the like. The eye can distinguish between light of different colors and brightnesses and convert this information into neural signals that are transmitted to the brain.
Glaucoma is a group of eye diseases that can lead to damage to the optic nerve and to vision loss. The most common types are open angle glaucoma, where the angle of drainage of intraocular fluid remains open, and unusual types include closed angle glaucoma and normotensive glaucoma. Over time, open angle glaucoma progresses slowly with no pain. Peripheral vision may begin to decline, followed by central vision, which if left untreated, may result in blindness. Glaucoma is permanent once vision loss occurs.
Aqueous humor is a transparent fluid that fills the area between the cornea, the front of the eye, and the lens. Aqueous humor is continuously secreted by the ciliary processes of the ciliary body into the posterior chamber of the eye and flows through the pupil into the anterior chamber, so there is a constant flow of fluid from the ciliary body to the anterior chamber of the eye. The aqueous humor fluid provides nutrients to the avascular structure of the eye (e.g., cornea and lens) and maintains ocular pressure. The pressure in the eye is determined by the balance between the production of intraocular water and the water flowing out through the canaliculi; many open angle glaucoma is due to increased resistance to aqueous humor drainage by the trabecular meshwork or schlemm's canal. Trabecular meshwork tissue typically allows aqueous humor to enter schlemm's canal, then to the water collection channel of the posterior wall of schlemm's canal, and then to the water vein, forming the schlemm's system. The uveoscleral outflow pathway refers to the diffusion of water out of the anterior chamber through the intercellular spaces between the ciliary muscle fibers.
For the treatment of glaucoma, intraocular implants may be implanted in the eye to facilitate outflow of water, thereby reducing intraocular pressure. Typical implantation procedures require relatively invasive surgery, risk excessive trauma to the eye, and require transitional handling of the implant. For example, in a typical implantation procedure, an incision is made through the sclera or cornea, and forceps or other similar manual grasping devices are used to insert the implant into the desired implantation site. And only one implant is introduced into the eye at a time. This requires reinstallation and repositioning of the forceps prior to insertion of each implant into the eye. Once the implant is implanted, the grasping device is removed and the incision is sutured. The existing operation is complex and requires low safety.
Aiming at the technical problems, the improvement is needed.

When the implant 402 is stably installed on the implantation device, firstly, a forward pushing force of the puncture push button 201 needs to be provided during operation to ensure that the puncture needle 205 can puncture epidermal tissue without withdrawing, when the puncture needle 205 passes through the tissue to reach a target implantation position, a reverse pushing force of the puncture push button 201 is provided to complete withdrawing of the puncture needle 205, at this time, the implant 402 and the delivery needle 301 reach the target position, one implant 402 can be implanted by applying the pushing force to the delivery operation button 304, at this time, the delivery operation button 304 is pressed down, the sliding block of the delivery operation button 304 reaches the second layer 匚 -shaped chute of the shell, the elastic force of the receiving spring 302 can be withdrawn, and since the rear end limit of the second layer 匚 -shaped chute is far away from the first layer 匚 -shaped chute, the delivery needle 301 can be withdrawn to the rear of the second implant 402, and the second implant 402 can be implanted again by applying the pushing force to the delivery operation button 304; the present invention preferably implants two implants 402, but is not limited to two (one or more implants in this embodiment), and the above steps are repeated as more implants are performed to complete the implantation of multiple implants 402.
Compared with the prior art, the method and the device can safely and reliably convey a plurality of implants to the target position in the operation process, provide great convenience for doctors and reduce operation risks.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Claims (4)
1. The multiple implantation device of the implant is characterized by comprising a shell, a puncture mechanism, an implant holding mechanism and a conveying mechanism, wherein the puncture mechanism comprises a puncture needle and a puncture push button connected with the puncture needle; the implant holding mechanism comprises a center needle, wherein the center needle is used for penetrating an implant, the center needle is sleeved in the penetrating needle and fixedly connected with the shell, and the center needle is provided with an abutting bulge for abutting against the placed implant; the conveying mechanism comprises a conveying needle and a conveying operation button, the conveying needle is sleeved outside the central needle, the caliber of the top end part of the conveying needle is smaller than the diameter of the implant, the tail end of the conveying needle is connected with the conveying operation button, and the conveying operation button pushes the conveying needle to axially move relative to the central needle so as to push the implant to be separated from the implantation target of the central needle in a propping way;
