[0039] The eye stone remover in the present application is mainly used for removing eye stones in ophthalmic outpatient service. By setting necessary hand-held structure and picking structure, the treatment conditions of medical staff in existing ophthalmic outpatient service are improved.
[0040] Embodiment 1
[0041] Referring to Figure 1 , in combination with Figures 2-4 , the eye stone remover in the present embodiment, the main structure includes a hand-held part and a removal part, and the removal part is connected to the side end of the hand-held part.
[0042] The hand-held part specifically includes an elongated hand-held rod 1, and the removal part includes a picking needle 2 connected to the front end of the hand-held rod 1. By connecting the picking needle 2 to the end of the elongated hand-held rod 1, the hand-held operation field of view of medical staff can be widened, and the distance between medical staff and patients is increased, the operation range of the operator is improved, and the operation difficulty is reduced.
[0043] In the process of removing stones, in order to enhance the structural strength of the picking needle 2, prevent the picking needle 2 from bending and breaking during operation after the field of view and operation range are increased, the picking needle 2 is a solid needle body, which can enhance the strength of the picking needle 2 itself. Compared with a hollow needle body, a solid needle body can provide more effective picking force, which facilitates the separation of stones from the eyelid plate. In order to more effectively remove stones, the tip of the solid needle body is provided with an inclined surface 21, which can better form a sharp needle tip structure, and can process stones of different sizes to improve operation efficiency.
[0044] The eye stone remover in the utility model can be in the form of separate setting of the picking needle 2 and the handheld rod 1 or in the form of integrated structure of the picking needle 2 and the handheld rod 1.
[0045] The picking needle 2 in the embodiment is separately set with the handheld rod 1 and is detachably connected to the handheld rod 1.
[0046] Through the setting mode, the root of the picking needle 2 can be inserted into the gap between the plurality of clamping claws 11 to realize clamping of the picking needle 2.
[0047] In order to more stably and reliably clamp, the inner side wall of each clamping claw 11 is provided with a clamping arc surface 12 with the same curvature, and the root of the picking needle 2 is inserted into the gap between the clamping arc surfaces 12.
[0048] Through the tangential contact between the outer side wall of the picking needle 2 and the clamping arc surfaces 12 on the plurality of clamping claws 11, the effective reliability of clamping and mounting of the picking needle 2 can be ensured.
[0049] Meanwhile, the handheld rod 1 further comprises a screwing taper head 13, the screwing taper head 13 is sleeved on the outer side of the plurality of clamping claws 11, and the root of the screwing taper head 13 is threadedly connected with the outer side wall of the handheld rod body 10.
[0050] In the specific assembly process, the picking needle 2 can be disassembled and replaced, after the screwing taper head 13 is screwed on the handheld rod body 10, the screwing taper head converges and shrinks different clamping claws 11, so that different clamping claws 11 and the clamping arc surfaces 12 on the clamping claws 11 form a hoop locking state on the root mounting part of the picking needle 2.
[0051] Meanwhile, after the operation of the picking needle 2 is completed, the screwing taper head 13 can be disassembled from the clamping rod body, so that the thinner picking needle 2 automatically falls off, or the thicker picking needle 2 is manually pulled out of the clamping claws 11, thereby realizing disassembly and replacement of the picking needle 2.
[0052] The eye stone remover in the embodiment can realize replacement of different specifications of the picking needle 2 through separate setting of the picking needle 2 and the handheld rod 1, and facilitates picking operation for different sizes of stones.
[0053] Embodiment 2
[0054] Referring to Figure 5The eye stone remover in the embodiment has the same main functional structure as that in the embodiment 1, and the difference is that the picking needle 2 is an integral structure with the hand rod 1, and the connection of the clamping claw 11 on the hand rod 1 is not involved.
[0055] Specifically, the front end of the hand rod 1 in the embodiment includes a connecting plane 20, and the integral connection of the hand rod 1 and the picking needle 2 is realized by welding the root of the picking needle 2 on the connecting plane 20 at the front end of the hand rod 1.
[0056] Regardless of the setting form, the eye stone remover in the utility model can be disinfected for medical treatment, so as to be reusable and reduce operation cost.
[0057] Specifically, the hand rod 1 and the picking needle 2 in the utility model are made of stainless steel, preferably medical stainless steel, which can resist high temperature and high pressure and can be disinfected by ethylene oxide.
[0058] In order to facilitate hand operation and prevent slipping, the outer side wall of the hand rod 1 is provided with an anti-slip mesh 30, which is processed on the hand rod 1 in the form of milling, so as to enhance the friction force in the hand operation process and improve the operation accuracy.
[0059] In combination with Figures 6-7 , and Figure 1 In the normal operation process, in addition to the removal of stones by the picking needle 2, a medical cotton swab 5 is also needed to assist and cooperate, press the eyelid plate or perform medical disinfection, so that the necessary plug-in structure of the cotton swab 5 needs to be arranged on the hand rod 1 to improve the use experience of medical staff.
[0060] Specifically, the utility model discloses that the plug-in counterbore 40 for the cotton swab 5 to extend into is arranged at the tail end of the hand rod 1, so that the cotton swab 5 can be plug-inly plugged into the tail end of the hand rod 1.
[0061] In order to be able to plug the cotton swab 5, a metal elastic ring 3 is installed inside the plug-in counterbore 40, preferably a stainless steel metal elastic ring 3 of the same material, so that the tail end of the cotton swab 5 can be elastically clamped by the metal elastic ring 3 after being inserted into the plug-in counterbore 40.
[0062] Referring to Figure 7 , specifically, the metal elastic ring 3 includes an open structure annular frame, the two ends of the annular frame in the axial direction are specifically C-shaped semicircular rings 31, and the clamping elastic sheets 32 are uniformly distributed on the circumferential direction of the annular frame, and the clamping elastic sheets 32 are specifically connected between the two C-shaped semicircular rings 31.
[0063] Each clamping spring 32 comprises a centering curved arc-shaped metal sheet, through this kind of setting form, after the metal elastic ring 3 is installed in the plug-in counterbore 40, the clamping spring 32 can elastically clamp the stick part of the inserted cotton swab 5, so that the cotton swab 5 is fixedly inserted in the tail end of the hand-held rod 1, and when used, the manual pulling force can break the clamping force of the clamping spring 32, so that the cotton swab 5 is more easily pulled out.
[0064] Based on the open structure of the metal elastic ring 3, it can be inserted into the plug-in counterbore 40 in the form of a plug, and at the same time, it can have a certain independent elastic variable in the plug-in counterbore 40, including radial deformation, and the outward expansion or contraction of the clamping spring 32 in the axial direction, which will not be repeated here.
[0065] In order to prevent the metal elastic ring 3 from being pulled out of the plug-in counterbore 40, a limiting block 4 is installed at the tail end of the hand-held rod 1, the limiting block 4 is threadedly connected with the tail end of the hand-held rod 1, and the installation of the limiting block 4 on the hand-held rod 1 is ensured.
[0066] From the perspective of protruding limiting, a through hole 41 for inserting the cotton swab 5 is arranged at the center of the limiting block 4, the hole diameter of the through hole 41 is slightly smaller than the hole diameter of the plug-in counterbore 40, and further, slightly smaller than the contour size of the C-shaped semicircular ring 31, which can block and limit the metal elastic ring 3, and can ensure the normal insertion of the cotton swab 5.
[0067] Further, the hole diameter of the through hole 41 is the same as the circumferential gap of the elastic centering part of the clamping spring 32, which can ensure effective limiting of the metal elastic ring 3 and normal insertion of the cotton swab 5.
[0068] The eye stone remover in the utility model can greatly improve the operation conditions of medical staff and is convenient for application in outpatient operation.
[0069] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.
[0070] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
