A Beagle spinal cord harvesting device

Abstract

This invention provides a spinal cord sampling device for beagle dogs, including an air compressor and a hose. The device uses an air compressor to pump air, which is then transferred to a connecting tube via the hose. A lever is then moved, causing a circular rotating plate to rotate. This rotating plate connects an exhaust port to an L-shaped through-hole. Air from the connecting tube is transferred through a first through-hole, a second through-hole, an air chamber, the exhaust port, and the L-shaped through-hole to an annular cavity. Air from the annular cavity is then transferred through a third through-hole to an annular airbag, used to firmly fix the thoracic vertebrae to a single-opening tube. The lever is then reversed, causing the circular rotating plate to connect the exhaust port to an exhaust groove. Air from the exhaust port is transferred through the exhaust groove to the single-opening tube. High-pressure gas is then blown from the thoracic vertebrae to the lumbar vertebrae through the spinal canal, allowing the spinal cord to exit naturally and completely from the lumbar vertebrae. This reduces the workload for the operator and can accommodate thoracic vertebrae of varying thicknesses.

Description

Technical Field

[0001] This utility model relates to the field of spinal cord sampling technology, and in particular to a beagle spinal cord sampling device. Background Technology

[0002] Beagles are ideal animal models for spinal cord research due to their physiological similarity, genetic stability, and ease of handling. The purposes of spinal cord sampling and dissection cover multiple fields, including disease mechanism exploration, drug development, and basic neuroscience. The research results have significant translational value for the prevention, diagnosis, and treatment of human spinal cord-related diseases.

[0003] Existing methods for obtaining spinal cord samples involve exposing the spinal cord through laminectomy under anesthesia, precisely locating and cutting the target segment, and cryopreserving or fixing the sample according to experimental needs. This requires the use of a microscope to cut the spinal cord and carefully peeling off the dura mater to expose the spinal cord tissue. This operation requires a high degree of concentration from the personnel involved, increasing their workload. If the personnel are distracted, spinal cord injury may occur during the sampling process. Therefore, a spinal cord sampling device for beagle dogs is proposed. Utility Model Content

[0010] The present invention has the following advantages due to the adoption of the above technical solution:

[0011] This invention uses an air compressor to pump air, which is then transmitted through a hose to a connecting pipe. The thoracic vertebrae are placed inside a single-opening tube and an annular airbag. The operator then moves a lever, causing a circular rotating plate to rotate. This rotating plate connects the exhaust port to an L-shaped through-hole.

The outer wall of the hose 2 is located on the inner wall of the connecting tube 31, and the single-opening tube 30 is located at one end of the connecting tube 31. The inner wall of the single-opening tube 30 is provided with an exhaust groove 9 and an L-shaped through hole 16, and an annular cavity 7 is provided inside the single-opening tube 30. The annular cavity 7 and the L-shaped through hole 16 are connected, and a third through hole 8 is uniformly provided on the inner wall of the annular cavity 7. The outer wall of the annular airbag 32 is located on the inner wall of the single-opening tube 30, and the third through hole 8 is provided on the inner wall of the annular cavity 30. The hole 8 is connected to the interior of the annular airbag 32. One side of the circular rotating plate 33 is rotatably connected to the inner wall of the single-opening tube 30 through a bearing. An air chamber 6 is opened inside the circular rotating plate 33. The outer wall of the circular rotating plate 33 is attached to the inner wall of the single-opening tube 30. A second through hole 5 is opened on one side of the circular rotating plate 33. An exhaust through hole 17 is opened on the outer wall of the circular rotating plate 33. The second through hole 5 and the air chamber 6 are connected. A first through hole 4 is opened at one end of the single-opening tube 30. The first through hole 4 is connected to the interior of the connecting pipe 31. An operation through hole 13 is opened on the outer wall of the single-opening tube 30. A lever 34 passes through the operation through hole 13. The operation through hole 13 is located on the outer wall of the circular rotating plate 33. One end of the spring 35 is located on the inner wall of the operation through hole 13. The other end of the spring 35 is located on the outer wall of the lever 34.

[0029] In this embodiment, specifically, a first sealing ring 11 is embedded in the outer wall of the circular rotating plate 33. The outer wall of the first sealing ring 11 is attached to the inner wall of the single-opening tube 30. The first sealing ring 11 is used to enhance the airtightness between the circular rotating plate 33 and the single-opening tube 30, and can also seal the L-shaped through hole 16.

[0030] In this embodiment, specifically, a second sealing ring 12 is provided on one side of the circular rotating plate 33. The side of the second sealing ring 12 away from the circular rotating plate 33 is attached to the inner wall of the single-opening pipe body 30. The second sealing ring 12 is provided to further enhance the airtightness between the circular rotating plate 33 and the single-opening pipe body 30.

[0031] In this embodiment, specifically, a rubber sleeve 10 is provided on the outer wall of the connecting tube 31. The rubber sleeve 10 is provided to improve the comfort of personnel holding the connecting tube 31.

[0032] In this embodiment, specifically, an exhaust pipe 14 penetrates the outer top wall of the single-opening tube 30. The exhaust pipe 14 is fixedly connected to the single-opening tube 30 and is connected to the annular cavity 7. A switch valve 15 is provided on the outer wall of the exhaust pipe 14. With the above-mentioned configuration, relevant personnel open the switch valve 15 to facilitate the discharge of gas in the annular airbag 32 and the annular cavity 7 through the exhaust pipe 14, which facilitates the removal of the thoracic vertebra after the sample collection is completed.

[0033] In operation, this invention works as follows: During dissection, a medical-grade electric saw is used to sever both ends of the thoracic and lumbar vertebrae. The severed thoracic vertebrae are then placed inside a single-opening tube 30 and an annular airbag 32. Subsequently, personnel move a lever 34, which rotates a circular rotating plate 33. This rotating plate connects the exhaust port 17 with the L-shaped through-hole 16. Then, personnel start the air compressor 1. The air generated by the air compressor 1 is transmitted through a hose 2 to the connecting pipe 31, where the first sealing ring 11... The second sealing ring 12 can enhance the sealing between the circular rotating plate 33 and the single-opening tube 30, preventing gas leakage. The gas in the connecting pipe 31 is transmitted to the annular cavity 7 through the first through hole 4, the second through hole 5, the air chamber 6, the exhaust through hole 17 and the L-shaped through hole 16. The gas in the annular cavity 7 is transmitted to the annular airbag 32 through the third through hole 8, causing the annular airbag 32 to inflate and tightly fix the thoracic vertebrae to the single-opening tube 30, preventing gas leakage between the single-opening tube 30 and the thoracic vertebrae.

[0034] Afterwards, the relevant personnel reversed the lever 34, which caused the circular rotating plate 33 to rotate. The circular rotating plate 33 caused the exhaust hole 17 to connect with the exhaust groove 9. The gas in the exhaust hole 17 was transmitted to the single-opening tube 30 through the exhaust groove 9. The first sealing ring 11 was used to block the channel of the L-shaped through hole 16 to prevent gas leakage in the annular cavity 7. Then, high-pressure gas was blown from the thoracic end to the lumbar end through the spinal canal, so that the spinal cord was blown out naturally from the lumbar end intact. The dissecting bottle was used to access the blown-out spinal cord at the end.

[0035] Afterwards, the relevant personnel release the lever 34, and the elastic potential energy of the spring 35 drives the lever 34 to move back to its original position. This causes the lever 34 to move the circular rotating plate 33 back to its original position, and the circular rotating plate 33 to move the L-shaped through hole 16 back to its original position. The L-shaped through hole 16 fits against the inner wall of the single-opening tube 30, and the first sealing ring 11 is used to seal the L-shaped through hole 16.

[0036] Then, the relevant personnel turn off the air compressor 1. When it is necessary to release the thoracic vertebra, the relevant personnel open the switch valve 15 to facilitate the discharge of gas from the annular airbag 32 and the annular cavity 7 through the exhaust pipe 14, so as to facilitate the removal of the thoracic vertebra after the sample has been taken.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
