Description

Technical Field

[0001] This utility model relates to the field of pearl oyster implantation surgery technology, and in particular to a pearl oyster cell suspension injection positioning device. Background Technology

[0002] Pearl culture involves implanting a pearl nucleus into the pearl oyster after it has matured through an internal surgical procedure. Small pieces of the same type of somatic cells are attached to the pearl nucleus, and the oyster is then implanted with the nucleus. The cells stimulate the oyster to secrete nacre, which then coats the nucleus to form a pearl. Injecting a cell suspension can produce a large number of rice-sized pearls.

[0003] Chinese patent document CN214385574U discloses a pearl nucleus implantation and cell fragment placement device, comprising a conduit-shaped placement device with a channel, an outlet, and an inlet. The diameter of the outlet port is smaller than the diameter of the channel. Several slots are evenly distributed at the outlet port along the radial direction of the placement device, with one end of each slot communicating with the outlet port. During the implantation procedure, a nucleus delivery device is used to aspirate the non-porous nucleus. The nucleus's mucus adheres to the cell fragments. The outlet of the placement device is aligned with the pearl-forming pearl position inside the pearl oyster. The delivery device is then moved from the inlet port along the inside of the placement device to the outlet port, accurately reaching the pearl-forming pearl position inside the pearl oyster. After implantation, the placement device is removed. This method eliminates the need for pre-drilling the nucleus, resulting in pearls without pore scars and thus higher economic value.

[0004] The existing technology has the following problems:

[0005] The locator is not equipped with a device for fixing it, so it needs to be held manually during use. When preparing cell suspensions, manual holding can easily cause the locator to become unstable, which may cause the needle of the syringe to scratch the pearl oyster. Summary of the Invention

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a pearl oyster cell suspension injection positioning device includes a base plate 1, a fixing seat 2 fixedly connected to the upper middle part of the base plate 1, a first telescopic rod 3 fixedly connected to the inner side of the fixing seat 2, a mechanism plate 4 fixedly connected to the upper side of the first telescopic rod 3, a fixing clamp 5 movably installed on the rear side of the mechanism plate 4, and a positioning mechanism 6 rotatably connected to the lower side of the mechanism plate 4.

[0027] The positioning mechanism 6 includes a rotating plate 61. The upper side of the rotating plate 61 is rotatably connected to the lower side of the mechanism plate 4 near the rear side. A rotating component 62 is movably installed on the lower side of the mechanism plate 4 near the right rear side. An adjusting seat 63 is rotatably connected to the front side of the rotating plate 61. A second rotating component 64 is movably installed on the outer side of the adjusting seat 63. A slide 617 is movably sleeved on the inner side of the adjusting seat 63. A motor 65 is fixedly connected to the upper side of the slide 617 near the left side. A rotating seat 66 is fixedly connected to the output end of the motor 65. A positioner body 67 is movably sleeved on the inner side of the rotating seat 66.

[0028] It should be noted that the first telescopic rod 3 is an electric push rod that can drive the mechanism plate 4 to move up and down. The fixing clamp 5 is used to fix the pearl oyster. The rotating component 62 and the rotating plate 61 have the same structural components. The rotating component 62 contains components such as a motor, gears, and gear rings. The motor is the same type of device as the motor 65. The motor 65 can be self-locking. The positioner body 67 is rotated manually. During this time, the motor 65 is not powered. After stopping, the motor 65 self-locks, so that the positioner body 67 is fixed.

[0029] like Figure 5 As shown, a slide rod 68 is fixedly connected to the lower side of the slide 617, and a mounting base 612 is fixedly connected to the lower side of the adjusting base 63. Several second telescopic rods 611 distributed in a ring are fixedly connected to the inner side of the side wall of the mounting base 612.

[0030] It should be noted that the second telescopic rod 611 is an electric push rod. Moving the slide block 617 up and down can drive the positioner body 67 to move up and down. Then the second telescopic rod 611 extends to fix the slide rod 68.

[0031] like Figure 5 As shown, a gripper sleeve 69 is fixedly connected to the outer side of the locator body 67 near the front, and a base plate 610 is fixedly connected to the lower side of the slide bar 68.

[0032] It should be noted that the gripper sleeve 69 and the bottom of the base plate 610 are both equipped with first pressure sensors. After gripping the gripper sleeve 69 and the base plate 610, the positioner body 67 and the slide bar 68 can be adjusted at will. When the appropriate position is reached, the first pressure sensor is pressed tightly, so that the first pressure sensor is subjected to a certain upper limit of force, which causes the positioner body 67 to be fixed by the rotating plate 61, the rotating component 62, the second telescopic rod 611 and the motor 65.

[0033] like Figure 5 As shown, a third telescopic rod 614 is fixedly connected to the upper side of the rotating seat 66, and the rear side of the third telescopic rod 614 is fixedly connected to the upper side of the positioner body 67 near the rear side.

[0034] It should be noted that the third telescopic rod 614 is an electric push rod. A second pressure sensor is provided on the front side of the positioner body 67. Pressing the second pressure sensor will cause the third telescopic rod 614 to extend, thereby driving the positioner body 67 to move backward.

[0035] like Figure 3 , Figure 4 As shown, a protective cover 615 is fixedly connected to the upper side of the rotating plate 61 near the front side, and a flexible sleeve 616 is fixedly connected between the upper side of the protective cover 615 near the front side and the upper side of the slide block 617 near the edge.

[0036] It should be noted that the protective cover 615 and the flexible sleeve 616 work together to prevent leakage from the gap between the adjusting seat 63 and the slide 617, and at the same time prevent the gear parts on the rotating assembly 62 from being exposed. This prevents water from spilling from the outside of the pearl oyster when it is handled, thus preventing sewage from falling onto the rotating assembly 62 or the area between the adjusting seat 63 and the slide 617.

[0037] like Figure 4 As shown, the upper side of the protective cover 615 is coated with Teflon.

[0038] It should be noted that the Teflon coating can improve the wear resistance of the upper side of the protective cover 615, thereby reducing the possible wear on the upper side of the protective cover 615 when adjusting the positioner body 67, and at the same time, it can facilitate the cleaning of the upper side of the protective cover 615.

[0039] like Figure 4 As shown, several ring-shaped clamping rods 613 are rotatably connected to the outer side of the locator body 67 near the front.

[0040] It should be noted that the clamping rod 613 is driven by a torsion spring, which can stabilize the injection needle when it is inserted into the positioner body 67.

[0041] The working principle of this utility model is as follows: First, the structural components on the rotating assembly 62 and the rotating plate 61 are identical. The rotating assembly 62 contains components such as a motor, gears, and a gear ring. This motor is the same type of device as motor 65. Motor 65 has an internal self-locking mechanism. The positioner body 67 is rotated manually, during which time motor 65 is not powered. After stopping, motor 65 self-locks, thus fixing the positioner body 67. The second telescopic rod 611 is an electric push rod that moves the slide block 617 up and down, thereby driving the positioner body 67. 7. The device moves up and down, then the second telescopic rod 611 extends, fixing the slide rod 68. First pressure sensors are located on the inner side of the gripping sleeve 69 and the lower side of the base plate 610. After gripping the gripping sleeve 69 and the base plate 610, the positioner body 67 and the slide rod 68 can be adjusted freely. When a suitable position is reached, the first pressure sensor is pressed tightly, causing it to be subjected to a certain upper limit of force. This results in the positioner body 67 being jointly fixed by the rotating plate 61, the rotating assembly 62, the second telescopic rod 611, and the motor 65. This is achieved through multiple sensors. The motor 65 allows for quick manual adjustment of the positioner body 67, followed by fixation. This ensures the positioner body 67 remains stationary when the syringe is inserted, preventing instability during manual gripping. The protective cover 615 and flexible sleeve 616 work together to prevent leakage from the gap between the adjusting seat 63 and the slide 617, and to prevent the gear components on the rotating assembly 62 from being exposed. This prevents water from spilling onto the rotating assembly 62 or the area between the adjusting seat 63 and the slide 617 when handling pearl oysters. The Teflon coating improves the wear resistance of the upper side of the protective cover 615, reducing potential wear during positioner body 67 adjustment and facilitating cleaning. The protective cover 615 and flexible sleeve 616 prevent the second rotating assembly 64 from being corroded by external sewage, and also prevent sewage from entering between the adjusting seat 63 and the second rotating assembly 64, thus protecting the components.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
