Description
Technical Field
The utility model relates to the technical field of animal surgery, in particular to a straight clamping device for animal surgery.
Background
In research on the brain, high resolution in vivo optical deep brain imaging has been a great challenge. Buried brain structures can be imaged early on by gradient index (GRIN) lenses embedded in the brain. But imaging is limited to the superficial brain region due to the severe attenuation in depth of the excitation and emission photons caused by tissue scattering. Although longer excitation wavelengths or red-shifted fluorescent markers can mitigate the scattering effect, imaging depth is still limited to 1-2mm in the mouse brain and imaging quality can decrease rapidly with increasing depth. To image deeper subcortical structures beyond this limit, a micro-scope has been used that relies on implantation of miniature gradient index (gradient refractive index lens, GRIN lens) lenses in the brain.
However, in the case of GRIN lens surgery, a straightener is required. The prior GRIN lens straightener is mostly made of metal materials and is fixed by screws. On the one hand, for glass products with the diameter of 0.5-1mm, such as fixed GRIN lens, the GRIN lens is easily damaged by excessive pressure; on the other hand, the diameter of the tail end of the straight device is too large, so that the surgical field is too large, and the use is very inconvenient.
Disclosure of Invention
The embodiment of the utility model aims to provide a straight clamp for animal surgery, which has a simple structure. The straightener is specially designed for animal surgery to implant GRIN lenses. The GRIN lens is not easy to be damaged by the hard plastic material, the tail end of the straightener is thinner, and the surgical space is not occupied.
In order to achieve the above-mentioned purpose of the embodiment, the embodiment of the utility model provides a clamp for animal surgery, the clamping end of the clamp is provided with a first inner cavity corresponding to the shape and size of GRIN lens, the top of the inner cavity is provided with a through hole, the first inner cavity is positioned in a second inner cavity of the clamp, a lens unloading assembly is arranged in the second inner cavity, the lens unloading assembly comprises a push rod provided with a flange, one end of the push rod is fixedly provided with a lens unloading piece corresponding to the through hole, and the other end of the push rod passes through a limiting plate in the second inner cavity and the tail of the clamp and is exposed; the push rod is also sleeved with a spring, one end of the spring is connected with the flange, and the other end of the spring is connected with the limiting plate.
The embodiment of the utility model has the advantages that the material of the straightener for animal surgery is hard plastic, and the straightener is manufactured through 3D printing. The structure is simple, the weight is light, the visual field is good when the animal GRIN lens operation is implemented, the GRIN lens can be easily clamped, and the GRIN lens is not easy to damage. Meanwhile, GRIN lens is easy to be stripped and convenient to use.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings that are needed in the description of the embodiments will be briefly described below, it being obvious that the drawings in the following description are only some embodiments of the present utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a perspective schematic view of a straightener for animal surgery in accordance with an embodiment of the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in FIG. 1, the front end, namely the clamping end, of the straight clamp is provided with a first inner cavity 1 corresponding to the GRIN lens shape and size, the top of the inner cavity is provided with a through hole 2, the first inner cavity 1 is positioned in a second inner cavity 3 of the straight clamp, a lens unloading assembly is arranged in the second inner cavity, the lens unloading assembly comprises a push rod 401 provided with a flange 402, one end of the push rod 401 is fixedly provided with a lens unloading piece 403 corresponding to the through hole 2, and the other end of the push rod passes through a limiting plate 404 in the second inner cavity 3 and the tail of the straight clamp and is exposed; the push rod 401 is also sleeved with a spring 405, one end of the spring 405 is connected with the flange 402, and the other end is connected with the limiting plate 404.
The main body structure of the straightener can be printed through 3D, and can be used after being installed. In use, the hand-held straight clamp aligns the clamping end first inner cavity 1 with the GRIN lens, and sleeves the GRIN lens into the first inner cavity 1. When the GRIN lens is taken out, the GRIN lens can be pushed out of the first inner cavity 1 by slightly pressing the push rod 401 protruding from the tail of the straight clamping device, and the push rod 401 is reset under the action of the spring.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model. Meanwhile, the parts in the drawings of the embodiments, which have the same functions and principles as those of the prior art, are not described herein again.
