Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal testing technology, and in particular to a spinal soft tissue fixation clamp for animal testing of a water jet surgical device. Background Technology
[0002] Animal testing refers to scientific research conducted in a laboratory using animals to gain new knowledge in biology, medicine, and other fields, or to solve specific problems. During animal testing, some steps require manipulation of the spinal soft tissue using water jet surgical equipment; in these cases, fixation clamps are needed to hold and secure the spinal soft tissue.
[0003] However, spinal soft tissues are mostly viscoelastic materials, relatively soft, and difficult to hold using traditional clamps. Currently, there is no accurate, reliable, and unified clamping method or standard. One existing soft tissue clamp uses a negative pressure clamp to adsorb soft tissue samples onto the clamp, achieving fixation. However, this method uses a porous material sheet to adsorb the soft tissue; different soft tissues have different mechanical properties, and the pore size of the porous material sheet is fixed, making it difficult to adjust the pore size according to actual needs, thus its applicability needs improvement. Therefore, an improved spinal soft tissue fixation clamp for animal experiments using water jet surgical equipment is proposed. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a spinal soft tissue fixation clamp for animal testing of water jet surgical equipment, in order to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.
[0006] To achieve the above objectives, one embodiment of this utility model provides a spinal soft tissue fixation clamp for animal testing using a water jet surgical device, comprising a clamping assembly and a suction assembly. The clamping assembly includes two suction heads, each with a plurality of suction holes on its inner side. An adjusting plate is rotatably connected inside the suction head, and the adjusting plate has adjusting holes corresponding one-to-one with the suction holes on the suction head. The adjusting plate is rotatably connected inside the suction head via an adjusting shaft. The clamping assembly also includes a mounting frame, within which a drive shaft is rotatably connected. A mounting plate is threaded onto the drive shaft, and the suction head is fixedly connected to the mounting plate. A connecting pipe is fixedly connected to the outer side of the suction head. The suction assembly includes a pump body and an air supply pipe disposed between the pump body and the connecting pipe.
[0007] Preferably, in any of the above embodiments, the adsorption head includes a disc and a ring fixedly connected to the disc, and both the disc and the ring are provided with a plurality of adsorption holes.
[0008] The above technical solution involves: a clamping assembly clamping the spinal soft tissue; an air extraction assembly extracting the gas from the clamping assembly; and using negative pressure to adsorb the soft tissue. An adsorption head, comprising a disc and a ring, is used to adsorb the soft tissue. The disc adsorbs the soft tissue from its end, while the ring adsorbs it from the side, assisting the disc in its operation and making the adsorption effect more reliable.
[0009] Preferably, in any of the above embodiments, a plurality of the adsorption holes are evenly arranged on the adsorption head, and the annulus of the adsorption head is an outwardly expanding conical annulus.
[0010] The above technical solution employs a plurality of adsorption pores evenly arranged on the adsorption head, ensuring adsorption effectiveness at all points on the adsorption head and thus improving the stability of adsorption on animal soft tissue. The annular structure of the adsorption head adopts a conical structure, facilitating the insertion of the end of the animal soft tissue into it and improving adsorption stability.
[0011] Preferably, in any of the above solutions, the mounting frame has a limiting groove on its side that restricts the rotation of the mounting plate, and one end of the drive shaft is fixedly connected to a handle.
[0012] The above technical solution employs a mounting frame that provides installation space for the drive shaft. Rotating the drive shaft, constrained by the mounting frame, causes the mounting plate to move horizontally, allowing adjustment of the suction head's position for easy fixation of animal soft tissue of varying lengths. A handle is provided at one end of the drive shaft for easy rotation by the operator.
[0013] Preferably, in any of the above solutions, the drive shaft is a bidirectional lead screw, and a limiting block is fixedly connected to the side of the mounting plate and disposed in the limiting groove.
[0014] The above technical solution employs a drive shaft that moves the mounting plates and the suction head. It uses a bidirectional lead screw, facilitating direct movement of the two mounting plates towards or away from each other. Limiting blocks are installed on the sides of the mounting plates, which, in conjunction with limiting grooves, limit the mounting plates to prevent displacement in other directions.
[0015] Preferably, of any of the above embodiments, a connecting flange is fixedly connected to the end of the connecting pipe, and a main valve is provided on the gas transmission pipe.
[0016] Preferably, as described in any of the above schemes, the gas supply pipe is further provided with an air buffer and a vent valve, and a vacuum controller is connected to the gas supply pipe.
[0017] The above technical solution involves using a gas supply pipe to allow other airflow. Activating the pump causes gas to flow, drawing gas out of the adsorption head and creating a negative pressure, which tightly adsorbs animal soft tissue. A connecting flange is installed on the connecting pipe for easy connection of the gas supply pipe to it.
[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0019] 1. This water jet surgical device for animal testing of spinal soft tissue fixation clamps comprises an suction head, suction holes, an adjusting plate, an adjusting shaft, a mounting frame, a drive shaft, and a mounting plate. During animal testing, the drive shaft is rotated according to the length of the soft tissue sample. Under the constraint of the mounting frame, the mounting plate is moved horizontally by the drive shaft, thus adjusting the position of the suction head. Depending on the type of soft tissue sample, the adjusting shaft is rotated, causing the adjusting plate to rotate. The suction holes on the adjusting plate and the suction holes on the suction head are staggered, allowing for adjustment of the actual hole diameter. This enables clamping and fixing of soft tissues from different types of animals, greatly improving its applicability.
[0020] 2. This water jet surgical device includes a spinal soft tissue fixation clamp for animal testing. The suction head, used to adsorb soft tissue, comprises a disc and a ring. The disc adsorbs soft tissue from the end, while the ring adsorbs it from the side, assisting the disc in its operation and ensuring a more reliable adsorption effect. Several adsorption holes are evenly distributed on the suction head to ensure effective adsorption at all points, thus improving the stability of the adsorption effect on animal soft tissue. The ring of the suction head has a conical structure, facilitating the insertion of the end of the animal soft tissue and enhancing adsorption stability.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] like Figures 1-4 As shown, this utility model includes a clamping assembly and a suction assembly. The clamping assembly includes two suction heads 1, each with a plurality of suction holes 2 on its inner side. An adjusting plate 3 is rotatably connected inside the suction head 1, and the adjusting plate 3 has adjusting holes that correspond one-to-one with the suction holes 2 on the suction head 1. The adjusting plate 3 is rotatably connected inside the suction head 1 via an adjusting shaft 4. The clamping assembly also includes a mounting frame 5, with a drive shaft 6 rotatably connected inside the mounting frame 5. A mounting plate 7 is threaded onto the drive shaft 6, and the suction head 1 is fixedly connected to the mounting plate 7. A connecting pipe 8 is fixedly connected to the outer side of the suction head 1. The suction assembly includes a pump body 10 and an air supply pipe 9 disposed between the pump body 10 and the connecting pipe 8.
[0031] Example 1: The adsorption head 1 includes a disc and a ring fixedly connected to the disc. Both the disc and the ring have several adsorption holes 2. A clamping assembly clamps the soft tissue of the spine, and a suction assembly extracts the gas from the clamping assembly, using negative pressure to adsorb the soft tissue. The adsorption head 1, used to adsorb soft tissue, includes a disc and a ring. The disc can adsorb soft tissue from its end, while the ring can adsorb soft tissue from its side, assisting the disc in its work and making the adsorption effect more reliable.
[0032] A number of adsorption holes 2 are evenly arranged on the adsorption head 1, and the annulus of the adsorption head 1 is an outwardly expanding conical annulus. The even arrangement of the adsorption holes 2 on the adsorption head 1 ensures the adsorption effect at all points on the adsorption head 1, thus improving the stability of the adsorption effect on animal soft tissue. The conical structure of the annulus of the adsorption head 1 facilitates the insertion of the end of the animal soft tissue into it, improving the adsorption stability.
[0033] Example 2: A limiting groove is provided on the side of the mounting frame 5 to restrict the rotation of the mounting plate 7, and a handle is fixedly connected to one end of the drive shaft 6. The mounting frame 5 provides installation space for the drive shaft 6. By rotating the drive shaft 6, the mounting plate 7 is moved horizontally by the drive shaft 6 under the constraint of the mounting frame 5, thereby adjusting the position of the suction head 1 to facilitate the fixation of animal soft tissues of different lengths. A handle is provided at one end of the drive shaft 6 to facilitate the rotation of the drive shaft 6 by the operator.
[0034] The drive shaft 6 uses a two-way lead screw, and a limiting block set in a limiting groove is fixedly connected to the side of the mounting plate 7. The drive shaft 6 moves the mounting plate 7 and the suction head 1. The use of a two-way lead screw facilitates direct movement of the two mounting plates 7 towards or away from each other. The limiting block set on the side of the mounting plate 7, in conjunction with the limiting groove, can limit the mounting plate 7 and prevent it from displacing in other directions.
[0035] Example 3: A connecting flange is fixedly connected to the end of the connecting pipe 8, and a main valve 11 is installed on the gas supply pipe 9. An air buffer 12 and a vent valve 14 are also installed on the gas supply pipe 9, and a vacuum controller 13 is connected to it. The gas supply pipe 9 is used to supply other flow; when the pump body 10 is started, it drives the gas flow, causing the gas inside the adsorption head 1 to be extracted, creating a negative pressure inside, thus tightly adsorbing animal soft tissue onto it. A connecting flange is provided on the connecting pipe 8 to facilitate connection of the gas supply pipe 9 to it.
[0036] The working principle of this utility model is as follows:
[0037] S1. When conducting animal experiments, the drive shaft 6 is rotated according to the length of the soft tissue sample. Under the constraint of the mounting frame 5, the mounting plate 7 is driven by the drive shaft 6 to move horizontally, thereby adjusting the position of the adsorption head 1.
[0038] S2. Depending on the type of soft tissue sample, rotate the adjusting shaft 4. The adjusting shaft 4 drives the adjusting plate 3 to rotate. The adsorption holes 2 on the adjusting plate 3 and the adsorption holes 2 on the adsorption head 1 are interleaved, so that the actual aperture can be adjusted. In this way, different types of animal soft tissue can be clamped and fixed.
[0039] Compared with the prior art, the present invention has the following advantages:
[0040] 1. This water jet surgical device for animal testing of spinal soft tissue fixation clamps comprises an adsorption head 1, adsorption holes 2, an adjusting plate 3, an adjusting shaft 4, a mounting frame 5, a drive shaft 6, and a mounting plate 7. During animal testing, the drive shaft 6 is rotated according to the length of the soft tissue sample. Under the constraint of the mounting frame 5, the mounting plate 7 is moved horizontally by the drive shaft 6, thus adjusting the position of the adsorption head 1. Depending on the type of soft tissue sample, the adjusting shaft 4 is rotated, causing the adjusting plate 3 to rotate. The adsorption holes 2 on the adjusting plate 3 and the adsorption holes 2 on the adsorption head 1 are staggered, allowing adjustment of the actual hole diameter. This enables clamping and fixing of soft tissues from different types of animals, greatly improving its applicability.
[0041] 2. This water jet surgical device includes a spinal soft tissue fixation clamp for animal testing. The suction head 1, used to adsorb soft tissue, comprises a disc and a ring. The disc adsorbs soft tissue from its end, while the ring adsorbs it from the side, assisting the disc in its operation and ensuring a more reliable adsorption effect. Several adsorption holes 2 are evenly distributed on the suction head 1 to ensure effective adsorption at all points, thus improving the stability of the adsorption effect on animal soft tissue. The ring of the suction head 1 has a conical structure, facilitating the insertion of the end of the animal soft tissue and improving adsorption stability.
