Description

Technical Field

[0001] The invention relates to the technical field of animal experiment auxiliary beds, and in particular to a monkey animal surgery platform based on ophthalmic surgery experiments. Background Art

[0002] At present, when conducting an eye flap experiment on the eyeballs of experimental monkeys, the experimental monkeys need to be anesthetized first, and then the anesthetized experimental animals are placed on the experimental bed and fixed with straps or elastic bands to avoid the monkeys shaking or shifting due to the monkey's own weight or the monkey's nerve beating during the experiment, thereby avoiding affecting the accuracy of the eye flap experiment. However, the traditional fixing structure has many defects. For example, the method of fixing the body with straps or elastic bands has a certain elasticity, so the strength of fixing the monkey's body with straps or elastic bands is low, and it is more difficult to tie the monkey's body with elastic bands, which affects the experiment. At the same time, the traditional experimental bed lacks a device to fix the monkey's head, which makes it difficult to align the flap-making device with the monkey's eyeball when they are in contact and cooperation, and the monkey's head is prone to shaking during the experiment, which affects the flap-making accuracy of the flap-making device. At the same time, due to the height limitation of the bed when making a flap on the eyeball, the experimenter needs to bend over to make a flap on the eyeball, which greatly consumes the experimenter's physical strength. At present, the experimental bed or experimental table in the existing technology can be lifted autonomously, but the lifting is the overall lifting of the bed or table, which makes it easy for the experimenter to touch the monkey's body when making a flap on the eyeball, and the monkey's head is easily shaken by the shaking of the body, which further affects the eyeball flap. Summary of the invention

[0003] In view of the shortcomings of the existing technology, the present invention provides a monkey surgical platform based on ophthalmic surgical experiments, which solves the problem that it is difficult to fix the monkey's body and head during traditional monkey experimental experiments and it is difficult to fix them according to the different body and head sizes of experimental monkeys.

[0004] To achieve the above-mentioned purpose, the present invention provides a monkey surgical platform based on ophthalmic surgical experiments, including a bed, wherein the end surface of the bed is divided into a monkey head area and a monkey body area, a head groove for accommodating the head of an external experimental monkey is provided on the bed corresponding to the monkey head area, and a body groove for accommodating the torso of an external experimental monkey is provided on the bed corresponding to the monkey body area, a head fixing part for fixing the head of the experimental monkey is provided in the head groove, a torso fixing part for fixing the torso of the experimental monkey is provided in the body groove, and a lifting component for realizing the overall lifting of the monkey head area or unilateral tilt lifting or the overall lifting of the bed is provided on the bed.

[0005] The above technical solution is beneficial in that: the experimenter places the anesthetized experimental monkey on the bed, and then aligns the head of the experimental monkey with the monkey head area and places it in the head slot, and then straightens the body of the experimental monkey and places it in the body slot, and the initial positioning of the monkey's body and head is achieved through the setting of the head slot and the body slot, and then the monkey's head is fixed by the head fixing part, and then the monkey's body is fixed by the body fixing part, so as to complete the fixation of the monkey as a whole, thereby facilitating experiments and operations on the monkey, and at the same time, the unilateral tilting lifting or overall lifting of the monkey head area or the lifting of the entire bed is achieved through the lifting component, so as to achieve single-point lifting of the monkey's head or tilting lifting of the monkey's head or lifting of the monkey as a whole under different experimental requirements, thereby adapting to different experimental requirements and facilitating experiments for experimenters, and at the same time, in the eye flap experiment, the single-point lifting or tilting lifting of the monkey's head is achieved to expose the monkey's head field of view and facilitate the experimenter to perform flap experiments on its eyeballs, thereby improving the experimental efficiency and experimental accuracy.

[0006] The present invention is further provided that: the head fixing part includes a plurality of head frames, and the plurality of head frames are distributed in a circumferential direction on the outer edge of the head groove, and the head frame includes an abutment plate for partially abutting against the head of an external experimental monkey, and the abutment plate is arranged in an arc shape and the inner wall of the abutment plate is an abutment surface for cooperating with the outer wall of the head of an external experimental monkey.

[0007] The benefit of adopting the above technical solution is that when fixing the monkey's head, the operator will locally abut the monkey's head with several abutment plates to achieve positioning of the monkey's head. At the same time, because the several abutment plates are arranged in a ring shape, the combination of several abutment plates can achieve local wrapping and positioning of the monkey's head, ensuring that the monkey's head will not shake or shift, which will affect the accuracy and efficiency of the eye flap experiment.

[0008] The present invention is further configured as follows: a movable plate is provided at the end of the abutment plate, a movable groove is opened at the beginning of the movable plate, the end of the abutment plate is swingably set in the movable groove, a small motor is provided at the beginning of the movable plate, and the output end of the small motor penetrates into the movable groove and is connected to the side wall of the end of the abutment plate.

[0009] The advantages of adopting the above technical scheme are as follows: when it is necessary to achieve abutment between the abutment plate and the monkey's head, the experimenter can start a small motor to swing the abutment plate, thereby achieving partial abutment between the abutment plate and the monkey's head, and use the small motor to swing the abutment plate in a fan shape, so that the abutment plate swings at a certain angle, thereby adapting to monkeys with different head circumferences, so that monkeys of different body shapes and sizes can be fixed, thereby increasing the experimental range and the range of eye flap making, and at the same time, the abutment plate is driven by a small motor to swing autonomously and fix to the monkey's head, thereby achieving adaptive positioning and fixation of the monkey's head, thereby avoiding the monkey's head being affected by external stress or self-influence and shaking during the corneal flap making experiment, which affects the flap making accuracy and efficiency.

[0010] The present invention is further provided with a sliding groove for inserting and sliding the movable plate corresponding to each movable plate position on the inner circumferential wall of the head groove, a matching sleeve is attached to the inner circumferential wall of the sliding groove, the matching sleeve is made of metal material, a suction cup type electromagnet is embedded in the movable plate, and the end face of the magnetic suction end of the suction cup type electromagnet is flush with the bottom wall of the movable plate.

[0011] The above technical solution is beneficial in that: before the abutment plate contacts the monkey's head, the movable plate is first moved so that the movable plate moves in the slide groove, thereby exposing the head groove for the monkey's head to be placed in the head groove, and then the movable plate is moved so that the inner wall at the end of the abutment plate first partially abuts the monkey's head. After the inner wall at the end of the abutment plate partially abuts the monkey's head, the experimenter starts the suction cup electromagnet to fix the movable plate in the slide groove, thereby achieving the fixation of the abutment plate, and then the abutment plate is swung by a small motor to achieve a large-scale abutment between the abutment surface of the abutment plate and the monkey's head. The monkey's head is partially wrapped and positioned by multiple abutment plates, thereby achieving adaptive positioning and fixation of the monkey's head, thereby avoiding the monkey's head from shaking due to external stress or its own influence in the corneal flap making experiment, thereby affecting the flap making accuracy and efficiency. At the same time, the movable plate is fixed by the suction cup electromagnet to avoid the abutment plate shaking or displacement causing positioning failure and fixation failure of the monkey's head, and at the same time avoid the monkey's head from shaking or displacement, thereby ensuring that the corneal flap making experiment accuracy and efficiency are affected.

[0012] The present invention further provides: an eyeball stretching structure is detachably provided on the inner wall of the abutment plate, and the eyeball stretching structure includes a first swinging plate, a second swinging plate and a stretching plate, a first rotating hole is provided on the inner wall of the abutment plate, a second rotating hole is provided at the starting end of the first swinging plate corresponding to the position of the first rotating hole, a first adjusting shaft is threadedly connected between the first rotating hole and the second rotating hole, a third rotating hole is provided at the end of the first swinging plate, a fourth rotating hole is provided at the starting end of the second swinging plate corresponding to the position of the third rotating hole, a second adjusting shaft is threadedly connected between the third rotating hole and the fourth rotating hole, an adjusting plate is provided on the outer wall of the stretching plate, and a fifth rotating hole is provided at the end of the second swinging plate. A sixth rotating hole is provided on the adjusting plate corresponding to the fifth rotating hole position, and a third adjusting shaft is threadedly connected between the fifth rotating hole and the sixth rotating hole, and a fixing plate and a clamping plate are relatively provided on the inner side wall of the support plate, and the fixing plate is fixedly connected to the inner side wall of the support plate, and a matching groove is provided on the inner side wall of the support plate along the opening direction of the support plate, and a guide shaft is provided in the matching groove, and the clamping plate is slidably provided along the opening direction of the support plate, and the starting end of the clamping plate is inserted into the matching groove and is provided with a through hole for the guide shaft to pass through, and a return spring is provided in the matching groove, and the starting end of the return spring is connected to the bottom wall of the matching groove, and the end of the return spring is connected to the bottom wall of the starting end of the clamping plate.

[0013] The above technical solution is beneficial in that: when the monkey's eyeball needs to be stretched so that the glass slide for external experiments can be pressed on the eyeball and can fully compress the monkey's eyeball, that is, before the experiment, the two sets of eyeball stretching structures are respectively installed on the two abutment plates close to the monkey's eyeball, the first rotating hole is coaxially aligned with the second rotating hole and the first adjusting shaft is screwed in so that the first adjusting shaft preliminarily fixes the first swinging plate on the abutment plate, and then the third rotating hole is coaxially aligned with the fourth rotating hole and the second adjusting shaft is screwed in so that the second adjusting shaft preliminarily fixes the second swinging plate on the abutment plate, and then the fifth rotating hole is coaxially aligned with the sixth rotating hole and the third adjusting shaft is screwed in so as to achieve the preliminary fixation of the stretching plate and the second swinging plate, and the stretching plate is located near the monkey's eyeball by swinging the first swinging plate and the second swinging plate, that is, the clamping plate and the fixing plate are located around the monkey's eyeball and because the clamping plate and the fixing plate are arranged relative to each other, The relative distance between the clamping piece and the fixing piece is the experimental groove for inserting the glass slide, that is, the experimental groove is aligned with the monkey's eyeball. When the monkey's eyeball is stretched open, the fixing piece is abutted against the monkey's lower eyelid, and then the clamping piece is pressed to make the clamping piece move toward the fixing piece until the clamping piece is located at the monkey's upper eyelid. When the clamping piece is pressed and moved, the initial end of the clamping piece will compress the reset spring, so that the reset spring is compressed and deformed and generates mechanical force. When the clamping piece is aligned and in contact with the monkey's upper eyelid, the experimenter no longer applies force to the clamping piece, so that the reset spring is deformed and reset and mechanical force is applied to the clamping piece, so that the clamping piece slides and resets, thereby achieving the effect of stretching the monkey's eyeball; the above-mentioned technical setting is used to realize the stretching of the monkey's eyeball, so as to facilitate the insertion of an external glass slide and the pressure on the monkey's eyeball, thereby facilitating the corneal flap making experiment, thereby improving the experimental efficiency and experimental accuracy.

[0014] The present invention is further provided that: the body fixing part includes a first fixed arm and a second fixed arm, the first fixed arm and the second fixed arm are cross-arranged, and a card slot is provided on the bottom wall at the center of the first fixed arm and the top wall at the center of the second fixed arm, and the two card slots are plug-matched, and the bottom wall of the first fixed arm and the bottom wall of the second fixed arm are both compression walls for contacting the body of the experimental monkey in the outside world, and limiting holes are provided on the bed body corresponding to the starting ends of the first fixed arm and the second fixed arm, and an electric push rod is provided in the limiting hole, and the two output ends of the electric push rod are respectively matched with the first fixed arm and the second fixed arm, and the radial cross-section of the first fixed arm and the second fixed arm is arranged in an arc shape.

[0015] The above technical solution is beneficial in that: before fixing the head of the experimental monkey, the first fixed arm and the second fixed arm are first swung so that the first fixed arm and the second fixed arm expose the body groove, and then the body of the experimental monkey is placed in the body groove, and then the first fixed arm and the second fixed arm are reset so that the first fixed arm and the second fixed arm cross each other and contact the body of the experimental monkey, that is, the compression wall is pressed on the body of the experimental monkey, and then the electric push rod is started so that the electric push rod moves down and the first fixed arm and the second fixed arm are pressed on the body of the experimental monkey, thereby completing the positioning and fixing of the body of the experimental monkey, thereby preventing the body of the experimental monkey from being affected by its own nerves or gravity or The accuracy and efficiency of the corneal flap making experiment are affected by shaking or displacement caused by external stress; in the above technology, the first fixed arm and the second fixed arm are cross-connected through a slot to avoid the first fixed arm and the second fixed arm being unable to be stacked, resulting in the failure of the first fixed arm and the second fixed arm combination to limit the monkey's body. In the above technology, the long diameter of the slot can be enlarged according to actual production needs and assembly needs to adapt to the position of the first fixed arm at different swing angles. At the same time, the inner wall of the slot can also be provided with an arc chamfer to ensure that the first fixed arm and the second fixed arm can be smoothly stacked to achieve compression limitation on the monkey's body.

[0016] The present invention further provides: a first fixing hole for the corresponding electric push rod output end to pass through is formed at the starting end of the first fixing arm and the starting end of the second fixing arm; a first fixing sleeve is provided in the first fixing hole; a second fixing hole for the adjacent and corresponding electric push rod output end to pass through is penetrated on the first fixing sleeve; a first tooth groove is formed circumferentially on the outer circumferential wall of the first fixing sleeve; a second tooth groove for mating and meshing with the first tooth groove is formed circumferentially on the inner circumferential wall of the first fixing hole; a third tooth groove is formed circumferentially on the outer circumferential wall of the electric push rod output end; a fourth tooth groove for mating and meshing with the third tooth groove is formed circumferentially on the inner circumferential wall of the second fixing hole.

[0017] The above technical solution is beneficial in that: when the first fixed arm and the second fixed arm are swung, the first fixed arm and the second fixed arm are swung with their corresponding limiting holes as base points, and the first fixed holes are coaxially aligned with the corresponding limiting holes during and after the first fixed arm and the second fixed arm are swung. When the first fixed arm and the second fixed arm are swung to a certain position, that is, when the first fixed arm and the second fixed arm are combined to limit the body of the experimental monkey, the operator inserts the first fixing sleeve into the two first fixing holes, and at this time, the first tooth groove is plugged and meshed with the second tooth groove, and the third tooth groove is plugged and meshed with the fourth tooth groove, thereby realizing the first fixing sleeve The rotational limitation between the first fixing hole and the output end of the electric push rod, that is, the rotational limitation between the first fixing sleeve and the first fixing hole is realized by the plug-in engagement of the first tooth groove and the second tooth groove, ensuring that the first fixing arm and the second fixing arm cannot swing, and the plug-in engagement of the third tooth groove and the fourth tooth groove realizes the rotational limitation between the first fixing sleeve and the electric push rod, further ensuring that the first fixing arm and the second fixing arm cannot swing, thereby realizing the limitation and fixation of the experimental monkey's body by the combination of the first fixing sleeve and the second fixing sleeve, thereby avoiding the failure of the first fixing sleeve and the second fixing sleeve to limit the experimental monkey's body, resulting in shaking or displacement of the experimental monkey's body.

[0018] The present invention further provides that: the ends of the first fixed arm and the second fixed arm are both swingably provided with a third fixed arm for pressing the legs of the experimental monkey in the outside world.

[0019] The benefit of adopting the above technical solution is that the third fixed arm in the above technology is used to limit the legs of the experimental monkey, and then when the electric push rod is started and drives the first fixed arm and the second fixed arm to move downward, it can drive the third fixed arm to move downward synchronously to achieve the limitation and fixation of the legs of the experimental monkey, further improving the fixing strength and limiting strength of the monkey's body.

[0020] The present invention is further provided with: an insertion shaft is provided at the end of the first fixed arm and the end of the second fixed arm, a third fixing hole is provided on the two third fixed arms, the two insertion shafts are respectively plugged into the two third fixing holes, a second fixing sleeve is provided on the two third fixing holes, a fourth fixing hole for the insertion shaft to be plugged into is penetrated through the second fixing sleeve, a fifth tooth groove is circumferentially provided on the outer circumferential wall of the second fixing sleeve, a sixth tooth groove for plugging and meshing with the fifth tooth groove is circumferentially provided on the inner circumferential wall of the third fixing hole, a seventh tooth groove is circumferentially provided on the insertion shaft, and an eighth tooth groove for plugging and meshing with the seventh tooth groove is circumferentially provided on the inner circumferential wall of the fourth fixing hole.

[0021] The use of the above technical solution is beneficial in that: when it is necessary to fix the monkey's legs, the experimenter swings the third fixed arm so that the third fixed arm swings with the third fixed hole as the base point until the third fixed arm swings to a certain position and compresses and limits the monkey's legs. Before and after the third fixed arm swings, the fourth fixed hole is always plugged with the plug shaft. Then the experimenter inserts the second fixed sleeve into the third fixed hole so that the second fixed sleeve is plugged with the third fixed hole and the plug shaft is plugged with the fourth fixed hole. At this time, the fifth tooth groove is plugged and meshed with the sixth tooth groove, so as to achieve the rotation limit of the second fixed sleeve in the third fixed hole, and the rotation limit between the second fixed sleeve and the plug shaft is achieved by plugging and meshing the seventh tooth groove with the eighth tooth groove, and further achieves the swing limit of the third fixed arm, so as to avoid the third fixed arm swinging or shaking to cause the limit failure of the monkey's legs. The setting of the above technology improves the limit and fixation of the monkey's legs, thereby improving the fixation strength and limit strength of the monkey's entire body.

[0022] The present invention further provides: the bed body is separately arranged and is divided into an upper operating bed and a lower lifting bed, the upper operating bed is separately arranged and is divided into a front lifting part and a rear lifting part by a head groove and a body groove, the lifting structure includes a plurality of lifting shafts which are separately arranged on the lower lifting bed and correspond to the positions of the front lifting part and the rear lifting part, the bottom walls of the front lifting part and the rear lifting part are provided with a plurality of lifting grooves along the height direction of the upper operating bed, a plurality of the lifting shafts correspond one-to-one to the plurality of lifting grooves and each lifting shaft is slidingly arranged in the corresponding lifting grooves, a universal ball is arranged on the top of each lifting shaft, the top wall of the lifting groove is spherically arranged and is partially fitted with the outer peripheral wall of the universal ball, the lifting groove is truncated cone-shaped and the diameter of the top wall of the lifting groove is smaller than the diameter of the bottom opening of the lifting groove, a driving cylinder is arranged corresponding to each lifting shaft position in the lower lifting bed, and the output ends of the driving cylinders are connected to the corresponding bottoms of the lifting shafts.

[0023] The advantages of adopting the above technical scheme are as follows: when the monkey's head needs to be lifted at a single point according to experimental requirements, it is only necessary to start the driving cylinder at the corresponding point so that the driving cylinder can drive the lifting shaft to lift, thereby realizing single-point lifting of the front lifting part; when the monkey's head needs to be tilted and lifted according to experimental requirements, it is only necessary to start the two groups of driving cylinders near the corners of the head slot so that the driving cylinder can drive the lifting shaft to lift, thereby realizing unilateral lifting of the front lifting part, thereby realizing the tilt of the front lifting part relative to the rear lifting part, that is, the tilt of the head slot relative to the rear slot; when the monkey needs to be lifted as a whole according to experimental requirements, it is only necessary to start all the driving cylinders so that the driving cylinders can drive the lifting shaft lifting interface to realize the lifting of the upper operating bed, that is, the upper operating bed. The bed is moved in the height direction by lifting the bed under the bed edge; in the above technology, when a single lifting axis or part of the lifting axis is lifted, the other lifting axes that have not been lifted are still in the lifting groove and do not change in height. When the front lifting part is lifted at a single point or on one side, the angle and height of the bed body will be changed locally. At this time, the relative angle of the lifting axes that have not been lifted and the corresponding lifting grooves will change. In the above technology, the universal ball and the lifting groove are arranged in a truncated cone shape so that the lifting axis that has not been lifted will not get stuck in the lifting groove, thereby ensuring the smoothness and smoothness of the lifting; the above technology is set to adapt to different experimental needs, and at the same time it is convenient for experimenters to perform corneal flap making or different experimental operations, thereby improving experimental efficiency and experimental accuracy.
