Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a bone tissue specimen flushing device for pathology department. Background Art

[0002] Due to various congenital or traumatic reasons, there are a large number of patients with bone defects in my country, and these patients often need to be implanted with bone repair materials to assist healing. Bone is a unique high-density connective tissue organ, which is mainly divided into two parts: cortical bone and cancellous bone. Among them, cancellous bone has a spongy structure, composed of interwoven trabeculae, and is distributed inside the bone. A significant advantage of cancellous bone is that it can effectively stimulate bone formation and has strong anti-infection ability. In addition, it can also form fragments, which are suitable for filling any cracks between bone ends. Therefore, cancellous bone is often used as an implanted bone repair material. Due to its microporous structure on the surface and the slightly alkaline environment rich in calcium ions formed by the slight dissolution of the material, cancellous bone has a high affinity with osteoblasts, which can promote the production of bone matrix collagen, further mineralize to form new bone tissue, and thus complete the bone tissue repair process.

[0003] Normally, cancellous bone harvested from the human body contains a lot of adipose tissue and other non-bone components (such as miscellaneous proteins), which need to be removed through pretreatment before implantation to avoid possible immune responses.

The bottom of the cleaning box 2 is connected to a drain pipe 5, and a rotating cleaning mechanism is provided in the cleaning box 2. The rotating cleaning mechanism includes a movable plate 61 and a fixed plate 62, a rotating placement frame 63, a screw motor 65, a driving motor 66 and a belt transmission assembly 67, the lower part of the left inner wall of the cleaning box 2 is connected with two front and rear guide rods, the movable plate 61 is slidably connected to the two guide rods, the right side of the bottom of the inner side of the cleaning box 2 is connected with a fixed plate 62, the upper part of the movable plate 61 is provided with a rotating placement frame 63 for placing bone tissue, the upper part of the fixed plate 62 is provided with a rotating chuck 64 engaged with the rotating placement frame 63, the rotating placement frame 63 includes a hollow rotating shaft 631 rotatably connected to the upper part of the movable plate 61, the right end of the hollow rotating shaft 631 is connected to a disk 632, and eight baffles 632 are connected to the right side surface of the upper edge of the disk 632 at uniform intervals in the circumferential direction. 33, the gap between two adjacent baffles 633 is smaller than the bone tissue, the rotating chuck 64 includes a baffle 641 rotatably connected to the upper part of the fixed plate 62, and eight plug blocks 642 are evenly spaced along the circumferential direction on the left side surface of the baffle 641, and the eight plug blocks 642 correspond to the eight baffles 633 one by one, and the shape of the plug blocks 642 is U-shaped. A screw motor 65 is provided at the lower part of the cleaning box 2, and the screw motor 65 includes a servo motor and a screw. The screw is rotatably connected to the lower part of the cleaning box 2, the screw is threadedly connected to the movable plate 61, and the screw passes through the fixed plate 62. The servo motor is installed at the lower part of the left outer wall of the cleaning box 2, and the output shaft of the servo motor is connected to the screw to control the servo motor Driving the lead screw to rotate can push the movable plate 61 to move rightward, and controlling the servo motor to drive the lead screw to reverse can push the movable plate 61 to move leftward. A driving motor 66 is installed on the left side of the movable plate 61, and the output shaft of the driving motor 66 is connected to the hollow rotating shaft 631 through a belt transmission assembly 67. The belt transmission assembly 67 consists of a large pulley, a small pulley and a belt. The large pulley is connected to the hollow rotating shaft 631, and the small pulley is connected to the output shaft of the driving motor 66. The belt is sleeved between the large pulley and the small pulley. A rubber plate 7 is connected to the baffle 633, and rubber strips 8 are connected to the right side surface of the disk 632 and the left side surface of the baffle 641 at intervals along the circumferential direction and radially.

[0034] First, the box cover 3 is rotated to open, and then a bone tissue specimen is placed in the rotating rack 63, and then the box cover 3 is closed, and then the screw motor 65 is controlled to work to drive the movable plate 61 to move rightward, and the movable plate 61 moves rightward to drive the entire rotating rack 63 to move rightward, so that the baffle 633 on the rotating rack 63 is inserted into the U-shaped plug 642 on the rotating chuck 64. The rotating rack 63 moves rightward to drive the bone tissue specimen therein to move rightward, and the bone tissue is then located between the rotating rack 63 and the rotating chuck 64. The cooperation between the rotating rack 63 and the rotating chuck 64 can block the bone tissue, and prevent the bone tissue from being thrown out of the rotating rack 63 when the rotating rack 63 rotates later. Then water is injected into the high-pressure nozzle 4, and the high-pressure nozzle 42 on the high-pressure nozzle 4 can spray water in a high-pressure form and directly spray it onto the bone tissue to achieve flushing of the bone tissue. While flushing the bone tissue, the driving motor 66 is controlled to work, so that the hollow shaft 631 is driven to rotate through the belt transmission component 67, thereby causing the entire rotating rack 63 to rotate, and the baffle 633 on the rotating rack 63 rotates to push the plug 642 to rotate with the baffle 641. The rotating rack 63 rotates synchronously with the rotating chuck 64, which can cause the bone tissue to roll in the rotating rack 63, thereby automatically changing the cleaning surface of the bone tissue, achieving comprehensive cleaning of the bone tissue, ensuring that the surface of the bone tissue can be fully and thoroughly cleaned, and thereby improving the cleaning effect. The rubber sheet 7 can protect the bone tissue from being directly damaged by collision with the baffle 633, and the rubber strip 8 can protect the bone tissue from being directly damaged by collision with the disk 632 and the baffle 641. The wastewater and residue after cleaning the bone tissue are discharged outward through the drain pipe 5. When the bone tissue is rinsed, the water injection into the high-pressure nozzle 4 is stopped, and then the screw motor 65 is controlled to work to drive the movable plate 61 to move to the left. The movable plate 61 moves to the right, driving the entire rotating placement frame 63 to move to the right and disengage from the rotating chuck 64. Then the rinsed bone tissue can be taken out from the rotating placement frame 63.

[0035] See also Figure 6-Figure 10The rotating placement frame 63 is provided with a clamping mechanism, which includes a slide bar 92, a clamping rod 93 and a driving assembly. Eight guide grooves 91 are evenly spaced along the circumferential direction on the disc 632. The eight guide grooves 91 are slidably connected with the slide bars 92. The slide bars 92 are in a T-shape. The right sides of the eight slide bars 92 are connected with clamping rods 93. The eight clamping rods 93 correspond to the eight baffles 633 one by one. The baffles 633 and the rubber plate 7 are provided with accommodating grooves 94 for accommodating the clamping rods 93. The clamping rods 93 are made of plastic material. The clamping rods 93 made of plastic material are 3 can not only stably clamp bone tissue, but also effectively avoid damage to bone tissue. A driving assembly is arranged between the rotating placement frame 63 and the movable plate 61. The driving assembly is used to drive the slide bar 92 to drive the clamping rod 93 to close and open. The driving assembly includes two front and rear rodless cylinders 95 installed on the upper left side of the movable plate 61. An annular slide rail 96 is connected between the sliders of the two rodless cylinders 95. An annular slide rail 96 is slidably connected to the annular slide rail 96. Four guide rods 98 are evenly spaced along the circumferential direction at the left end of the hollow rotating shaft 631. The guide rods 98 are connected to the left end of the hollow rotating shaft 631. The rod 98 passes through the annular slider 97. The right side of the annular slider 97 is connected to a sleeve 99. The sleeve 99 is located in the hollow shaft 631. The middle part of the disk 632 is rotatably connected to a spline sleeve 910. The spline sleeve 910 is located in the sleeve 99. The outer wall of the spline sleeve 910 is connected to a connecting block 911. The shape of the connecting block 911 is a herringbone. Three arc grooves 912 are evenly spaced along the circumference on the hollow shaft 631 for the herringbone connecting block 911 to rotate. The herringbone connecting block 911 is connected to a circular plate 913. The circular plate 91 3 sets are arranged on the hollow rotating shaft 631 and are located on the left side of the disk 632. Eight inclined grooves 914 are evenly spaced along the circumferential direction on the circular plate 913. The eight slide bars 92 correspond to the eight inclined grooves 914 one by one. The slide bars 92 are located in the corresponding inclined grooves 914. A spline shaft 915 is connected to the right side of the annular slider 97. The spline shaft 915 is located in the sleeve 99 and inserted in the spline sleeve 910. A spiral groove 916 is opened on the outer wall of the spline sleeve 910. A ball 917 is connected to the inner wall of the sleeve 99. The ball 917 is located in the spiral groove 916.

[0036] When the bone tissue is flushed, the rodless cylinder 95 is controlled to drive the annular slide rail 96 with the annular slider 97 to move to the right, thereby pushing the sleeve 99 with the ball 917 therein to move to the right. The ball 917 moves to the right and cooperates with the spiral groove 916 on the spline sleeve 910 to push the spline sleeve 910 to rotate. The rotation of the spline sleeve 910 drives the circular plate 913 to rotate through the connecting block 911. The rotation of the circular plate 913 drives the eight sliding rods 92 to close through the eight inclined grooves 914 thereon, so that the eight clamping rods 93 close and clamp the bone tissue. Then, the driving motor 66 is controlled to drive the hollow shaft 631 to rotate at high speed, thereby driving the disc 632 to rotate at high speed. The hollow shaft 631 rotates at high speed and pushes the annular slider 97 to rotate at high speed through the guide rod 98. The annular slider 97 rotates at high speed and drives the sleeve 99 and the spline shaft 915 to rotate at high speed. The spline shaft 915 rotates at high speed and drives the spline sleeve 910 to rotate at high speed. The spline sleeve 910 rotates at high speed and drives the circular plate 913 to rotate at high speed through the connecting block 911. Therefore, it can be ensured that the hollow shaft 631 can drive the disc 632 to rotate while driving the circular plate 913 to rotate synchronously, thereby ensuring the stability of the position of the slide rod 92 and ensuring that the clamping rod 93 firmly clamps the bone tissue. The high-speed rotation of the disc 632 pushes the sliding rod 92 to rotate with the clamping rod 93 at a high speed. Since the bone tissue is clamped by the clamping rod 93, the high-speed rotation of the clamping rod 93 can drive the bone tissue to rotate at a high speed, so as to use the centrifugal force to remove the waste liquid remaining on the surface of the bone tissue, thereby avoiding residual waste liquid on the surface of the bone tissue. Since the bone tissue is clamped by the clamping rod 93, it will not collide with the rotating placement rack 63 and the rotating chuck 64 and be damaged when it rotates at a high speed for dehydration. When the dehydration of the bone tissue is completed, the rodless cylinder 95 is controlled to drive the annular slide rail 96 with the annular slider 97 to move to the left, thereby pulling the sleeve 99 with the ball 917 therein to move to the left. The ball 917 moves to the left and cooperates with the spiral groove 916 on the spline sleeve 910 to push the spline sleeve 910 to reverse. The reversal of the spline sleeve 910 drives the circular plate 913 to reverse through the connecting block 911. The reversal of the circular plate 913 pushes the eight slide rods 92 to open through the eight inclined grooves 914 thereon, thereby making the eight clamping rods 93 open to loosen the bone tissue, and then the bone tissue can be taken out from the rotating placement rack 63. The annular slider 97 moves to the left, driving the spline shaft 915 to move to the left. After the spline shaft 915 moves to the left, it is still inserted in the spline sleeve 910, thereby ensuring that the hollow rotating shaft 631 can drive the disc 632 to rotate while driving the circular plate 913 to rotate synchronously, thereby ensuring that when cleaning bone tissue, the sliding rod 92 and the clamping rod 93 remain in an open state to prevent the clamping rod 93 from hindering the cleaning of bone tissue.

[0037] See also Figure 11-Figure 12A wall scraping mechanism is provided in the cleaning box 2, and the wall scraping mechanism includes a U-shaped scraper 101 which is slidably arranged in the cleaning box 2 and can move up and down. The outer wall of the U-shaped scraper 101 is in close contact with the inner wall of the cleaning box 2. A pulling component is provided between the box cover 3 and the U-shaped scraper 101, and the pulling component includes a spring 102, a fixed pulley I 103, a fixed pulley II 104 and a pull rope 106. The lower parts of the outer walls on the front and rear sides of the cleaning box 2 are both symmetrically rotatably connected to two fixed pulleys I 103, and the upper parts of the outer walls on the left and right sides of the cleaning box 2 are both rotatably connected to the front and rear two fixed pulleys II 104. The left and right sides of the box cover 3 The top of each scraper 101 is connected with a pull rod 105, and the left and right sides of the bottom of the U-shaped scraper 101 are connected with two front and rear pull ropes 106. The four pull ropes 106 correspond to the four fixed pulleys Ⅰ103 one by one. The pull rope 106 first passes around the corresponding fixed pulley Ⅰ103, and the two pull ropes 106 on the left side are inserted between the two fixed pulleys Ⅱ104 on the left and connected to the pull rod 105 on the left side. The two pull ropes 106 on the right side are inserted between the two fixed pulleys Ⅱ104 on the right and connected to the pull rod 105 on the right. The four corners of the top of the U-shaped scraper 101 are connected with springs 102, and the top of the spring 102 is connected to the upper part of the inner wall of the cleaning box 2.

[0038] When the box cover 3 is rotated to open upward and backward, the pull rope 106 is pulled by the pull rod 105, so that the pull rope 106 pulls the U-shaped scraper 101 downward, and the spring 102 is stretched accordingly. The downward movement of the U-shaped scraper 101 can effectively scrape off the residual waste liquid adhering to the inner wall of the cleaning box 2, ensuring that the residual waste liquid is discharged downward in time, and preventing the residual waste liquid from being retained on the inner wall of the cleaning box 2 and affecting subsequent operations. When the box cover 3 is rotated forward and downward to close, the pull rope 106 is loosened, and under the reset action of the spring 102, the U-shaped scraper 101 is pulled upward to reset, and the U-shaped scraper 101 pulls the pull rope 106 to tighten when it moves upward.
