Abstract

This invention discloses a hemostatic bone wax delivery device for minimally invasive spinal surgery, belonging to the technical field of minimally invasive spinal surgical instruments. The device includes a handle with a movable groove at its top and a first mounting groove at its bottom. A fixed seat is located at the bottom of the first mounting groove, and a telescopic mechanism is installed at its center. A pushing mechanism is installed within the movable groove, providing thrust to the telescopic mechanism.

Description

Technical Field

[0001] This invention belongs to the field of minimally invasive spinal surgical instruments technology, specifically relating to a bone wax delivery device for hemostasis under a minimally invasive spinal surgical endoscope. Background Technology

[0002] Bleeding during minimally invasive endoscopic spinal surgery is mainly divided into two types: muscle bleeding and bony bleeding. Electrodes are used in minimally invasive endoscopic surgery for hemostasis. While electrodes are highly effective at stopping muscle bleeding, their ability to stop bleeding from bony structures is weaker. Surgeons still use bone wax to fill the hemostatic points for hemostasis in bony structures. Currently, in clinical practice, there are no dedicated instruments for bone wax in minimally invasive endoscopic spinal surgery. Surgeons use instruments such as nerve dissectors or drills from open spinal surgery as carriers for bone wax to achieve hemostasis in bony structures during minimally invasive endoscopic spinal surgery.

[0003] Currently, when stopping bleeding in bony structures, open surgical instruments are typically used to deliver hemostatic bone wax to fill the bleeding point. However, this procedure usually requires the surgeon to rotate their wrist and apply external force to fill the bleeding point with bone wax. Furthermore, the operating opening is limited by the minimally invasive endoscopic surgery, and if the wrist rotation angle is insufficient, the bleeding point cannot be reached. In addition, the surgeon's wrist rotation can easily affect the observation lens, thus affecting the surgeon's endoscopic observation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a bone wax delivery device for hemostasis under endoscopic spinal minimally invasive surgery.

[0005] The technical solution adopted to solve the above technical problems is: a bone wax delivery device for hemostasis under spinal minimally invasive surgery, including a handle, wherein a movable groove is provided at the top of the handle and a first mounting groove is provided at the bottom of the handle; The bottom of the first mounting slot is provided with a fixed seat, and a telescopic mechanism is installed in the center of the first mounting slot. A pushing mechanism is installed in the movable slot, and the pushing mechanism can provide thrust to the telescopic mechanism. The top of the handle is equipped with an adjustment mechanism for pushing the mechanism, and the bottom of the handle is provided with a delivery mechanism, in which a filling component is installed.

[0006] Furthermore, the movable groove has a first threaded hole at its inner top, the handle has a tapered groove near the top of the first mounting groove, and a positioning groove is provided between the movable groove and the tapered groove.

[0007] Through the above technical solution, the first threaded hole facilitates the subsequent adjustment mechanism to adjust the elastic force of the pushing mechanism, and the positioning groove is used to position and align the parts of the pushing mechanism.

[0008] Furthermore, the fixed base has a second threaded groove at its internal center.

[0009] The above technical solution facilitates the assembly of different filling components, thereby delivering hemostatic bone wax to bleeding points in different bony structures for better hemostasis. At the same time, the top of the fixing base is designed with an arc surface, which makes it easy to align the base.

[0010] Furthermore, the telescopic mechanism includes a base disposed on the top of the fixed seat, a positioning column fixedly connected to the top center of the base, a movable column fixedly connected to the top of the positioning column, a first spring fixedly connected to the outer side of the top of the base, the positioning column and the movable column both located within the first spring, a communicating circular groove opened at the center of the base, the positioning column and the movable column, a cylinder slidably connected within the circular groove, a fixed circular plate fixedly connected to the center of the outer wall of the cylinder, a plurality of second springs fixedly connected to the top of the fixed circular plate, a second mounting groove opened inside the first mounting groove near the fixed circular plate, and the bottom ends of the plurality of second springs fixedly connected to the bottom of the second mounting groove.

[0011] With the above technical solution, when delivering hemostatic bone wax, the operator pushes the handle forcefully, causing the top of the conical groove to compress the first spring, causing the first spring to contract. At the same time, the first mounting groove, the conical groove, and the positioning groove move upward. When the top of the positioning post is stuck inside the positioning groove, it drives the entire movable post to be aligned. Since the volume of the first mounting groove is larger than the volume of the base, the positioning post, and the movable post, when the second spring is compressed, the base, the positioning post, and the movable post are in an inclined state until the positioning post is stuck inside the positioning groove. Only then is the entire device aligned, which facilitates subsequent insertion into the pushing mechanism. At the same time, under the action of the pushing mechanism, the cylinder is pushed, and the cylinder pushes the filling component, thereby compressing the hemostatic bone wax and delivering the hemostatic bone wax to the bleeding point.

[0012] Furthermore, the pushing mechanism includes a pushing seat disposed at the bottom of the movable groove, a circular hole is provided at the center of the bottom of the pushing seat, a top column is fixedly connected to the top of the circular hole, and a third spring is fixedly connected to the top of the pushing mechanism.

[0013] With the above technical solution, when the surgeon pushes the handle, the movable column is tilted, so that the top of the movable column is against the bottom of the pusher seat and is not locked into the round hole. When the handle continues to move downward, the pusher seat compresses the third spring at the top, and at the same time, the top of the positioning column slowly locks into the positioning groove. When the positioning column is fully locked into the positioning groove, the positioning column is in a straightened state, which drives the movable column to straighten and locks into the round hole. Under the action of the third spring, the pusher seat is reset, which drives the top column to move downward quickly, thereby pushing the cylinder and pushing the filling component to deliver the hemostatic bone wax. Through the mechanical principle of the instrument, mechanical energy is converted into kinetic energy. The hemostatic bone wax can be firmly pressed onto the bleeding point by the pressure of the spring parts without the surgeon needing to rotate his wrist. Moreover, no wrist rotation is required, only the handle needs to be pushed, which does not affect the surgeon's observation of the lens, thereby improving the surgical effect.

[0014] Furthermore, the adjustment mechanism includes a threaded disc fixedly connected to the top of the push seat, a connecting post fixedly connected to the top center of the threaded disc, an adjusting wheel fixedly connected to the top of the connecting post, and the threaded disc being threadedly connected to the first threaded hole.

[0015] With the above technical solution, when it is necessary to adjust the elastic force of the third spring, that is, the pushing force of the top column, the adjusting wheel is rotated, which drives the connecting column to rotate, which in turn drives the threaded disc to rotate on the first threaded hole, thereby causing the threaded disc to rise or fall, thus realizing the adjustment of the elastic force of the third spring. The surgeon can adjust the appropriate force of the top column according to the bone thickness below the bleeding point and the degree of osteoporosis of the patient, thereby improving the surgical effect.

[0016] Furthermore, the delivery mechanism includes a delivery tube, the top of the outer wall of the delivery tube is provided with a third threaded groove, the delivery tube is threaded to the inner wall of the fixing seat through the third threaded groove, the bottom end of the delivery tube is fixedly connected with a plurality of fixing teeth, and the center of the inner wall of the delivery tube is fixedly connected with a buckle.

[0017] With the above technical solution, when delivering hemostatic bone wax, the bottom end of the delivery tube is aligned with the bleeding point on the bone surface, and multiple fixing teeth are used to fix it on the bone surface to prevent the delivery tube from shifting during delivery. This ensures precise alignment with the bleeding point, allowing the hemostatic bone wax to be delivered in one go, improving surgical efficiency. The clips prevent the filling component parts from falling off. Since the delivery tube structures of the first, second, and third filling mechanisms are the same, when changing different filling components, the delivery tube can be rotated to separate the third threaded groove from the second threaded groove, thereby removing the delivery tube. This facilitates the replacement of different filling components and makes it convenient for use with different bone structure bleeding points.

[0018] Furthermore, the filling component is a first filling mechanism, which includes a first pressure rod disposed inside the delivery tube, a first push block fixedly connected to the top end of the first pressure rod, a first pressure head fixedly connected to the bottom end of the first pressure rod, and multiple notches opened on the outer wall of the first pressure head.

[0019] With the above technical solution, when delivering hemostatic bone wax, the top of the first pusher is flush with the top of the delivery tube, leaving a cavity between the bottom of the first pressure head and the bottom of the delivery tube. The surgeon then places the hemostatic bone wax into the cavity. Due to the adhesiveness of the hemostatic bone wax, it prevents the first pressure rod from sliding downward. When multiple fixing teeth are fixed on the bone surface, and under the push of the cylinder, the first pusher and the first pressure rod are pushed, thereby causing the first pressure head to quickly squeeze out the hemostatic bone wax, thus firmly pressing it onto the bleeding point. The hemostatic bone wax fills the hemostatic point under pressure, and excess hemostatic bone wax will be discharged upward along multiple notches to prevent excessive bone wax at the bleeding point on the bone surface. Furthermore, the bottom of the first pressure head is designed at 0 degrees, thus fitting the bleeding point of the bone structure at the corresponding angle.

[0020] Furthermore, the filling component is a second filling mechanism, which includes a second pressure rod, a second push block fixedly connected to the top of the second pressure rod, and a second pressure head fixedly connected to the bottom of the second pressure rod.

[0021] With the above technical solution, when multiple fixing teeth are fixed on the bone surface, the second pusher and the second pressure rod are pushed by the cylinder, thereby driving the second pressure head to quickly squeeze out the hemostatic bone wax, which is then firmly pressed on the bleeding point. The hemostatic bone wax fills the bleeding point under pressure, and the bottom of the second pressure head is designed at 60 degrees to fit the bleeding point of the bone structure at the corresponding angle.

[0022] Furthermore, the filling component is a third filling mechanism, which includes a third pressure rod, a third push block fixedly connected to the top of the third pressure rod, and a third pressure head fixedly connected to the bottom of the third pressure rod.

[0023] With the above technical solution, when multiple fixing teeth are fixed on the bone surface, the third pusher and the third pressure rod are pushed by the cylinder, thereby driving the third pressure head to quickly squeeze out the hemostatic bone wax, which is then firmly pressed on the bleeding point. The hemostatic bone wax fills the bleeding point under pressure, and the bottom of the third pressure head is designed at 30 degrees to fit the bleeding point of the bone structure at the corresponding angle.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a handle, a telescopic mechanism and a pushing mechanism. The mechanism converts mechanical energy into kinetic energy through the mechanical principle of the instrument. The surgeon does not need to rotate his wrist to exert force. The pressure of the spring parts can firmly press the hemostatic bone wax onto the bleeding point. Moreover, the surgeon does not need to rotate his wrist. He only needs to push the handle. This does not affect the surgeon's observation of the lens, thereby improving the surgical effect. (2) The present invention designs an adjustment mechanism. The surgeon can adjust the appropriate force of the top column according to the bone thickness below the bleeding point and the degree of osteoporosis of the patient, thereby improving the surgical effect. (3) The present invention designs a filling component. The filling component has a pressure head with 0 degrees, 30 degrees and 60 degrees. The appropriate filling component can be selected according to the bone structure bleeding point at different angles so that the instrument fits the bone surface at different angles more closely, thereby facilitating the delivery of hemostatic bone wax.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-10 As shown in Embodiment 1: The spinal minimally invasive surgical endoscope hemostatic bone wax delivery device of this embodiment includes a handle 1. The top of the handle 1 has a movable groove 11, and the bottom of the handle 1 has a first mounting groove 13. The top of the movable groove 11 has a first threaded hole 12. The handle 1 has a conical groove 14 near the top of the first mounting groove 13. A positioning groove 15 is provided between the movable groove 11 and the conical groove 14. The first threaded hole 12 facilitates the subsequent adjustment mechanism 5 to adjust the elastic force of the pushing mechanism 4. The positioning groove 15 is used to position and align the parts of the pushing mechanism 4. The bottom of the first mounting groove 13 has a fixed seat 2. The center of the fixed seat 2 has a second threaded groove 21, which facilitates the assembly of different filling components 7, thereby delivering hemostatic bone wax to bleeding points in different bony structures for better hemostasis. At the same time, the top of the fixed seat 2 is designed with an arc surface, which facilitates the alignment of the base 301.

[0029] like Figures 1-10As shown, a telescopic mechanism 3 is installed at the center of the first mounting groove 13. The telescopic mechanism 3 includes a base 301 disposed on the top of the fixed base 2. A positioning post 302 is fixedly connected to the top center of the base 301. A movable post 303 is fixedly connected to the top of the positioning post 302. A first spring 304 is fixedly connected to the outer side of the top of the base 301. The positioning post 302 and the movable post 303 are both located within the first spring 304. A circular groove 305 is formed at the center of the base 301, the positioning post 302, and the movable post 303. A cylinder 306 is slidably connected within the circular groove 305. A fixed circular plate 307 is fixedly connected to the center of the outer wall of the cylinder 306. A plurality of second springs 308 are fixedly connected to the top of the fixed circular plate 307. A second mounting groove 309 is formed inside the first mounting groove 13 near the fixed circular plate 307. The bottom ends of the plurality of second springs 308 are connected to the second mounting groove 309. With the bottom fixed connection, when delivering hemostatic bone wax, the operator pushes the handle 1 forcefully, causing the top of the conical groove 14 to compress the first spring 304, causing the first spring 304 to contract. At the same time, the first mounting groove 13, the conical groove 14, and the positioning groove 15 move upward. When the top of the positioning post 302 is stuck inside the positioning groove 15, it drives the entire movable post 303 to be aligned. Since the volume of the first mounting groove 13 is larger than the volume of the base 301, the positioning post 302, and the movable post 303, when the second spring 308 is compressed, the base 301, the positioning post 302, and the movable post 303 are in an inclined state until the positioning post 302 is stuck inside the positioning groove 15. Only then is the entire device aligned, making it convenient to insert into the pushing mechanism 4. At the same time, under the action of the pushing mechanism 4, the cylinder 306 is pushed, and the filling component 7 is pushed through the cylinder 306, thereby compressing the hemostatic bone wax and delivering the hemostatic bone wax to the bleeding point.

[0030] like Figures 1-10As shown, a pushing mechanism 4 is installed in the movable groove 11. The pushing mechanism 4 provides thrust to the telescopic mechanism 3. The pushing mechanism 4 includes a pushing seat 401 located at the bottom of the movable groove 11. A circular hole 402 is opened at the center of the bottom of the pushing seat 401. A top post 403 is fixedly connected to the top of the circular hole 402. A third spring 404 is fixedly connected to the top of the pushing mechanism 4. When the operator pushes the handle 1, the movable post 303 is tilted, so that the top of the movable post 303 is against the bottom of the pushing seat 401 and is not stuck in the circular hole 402. When the handle 1 continues to move downward, the pushing seat 401 compresses the top third spring 404, and at the same time, the top of the positioning post 302 slowly gets into the positioning groove 15. Internally, when the positioning post 302 is fully engaged in the positioning groove 15, the positioning post 302 is in a centered state, which in turn drives the movable post 303 to be centered. The centered movable post 303 is then engaged in the round hole 402. Under the action of the third spring 404, the push seat 401 is reset, which drives the top post 403 to move downward quickly, thereby pushing the round post 306 and the filling component 7 to deliver the hemostatic bone wax. Through the mechanical principle of the instrument, mechanical energy is converted into kinetic energy. The hemostatic bone wax can be firmly pressed onto the bleeding point by the pressure of the spring parts without the surgeon needing to rotate his wrist. Moreover, it does not require wrist rotation; only the handle 1 needs to be pushed. This does not affect the surgeon's observation of the lens, thereby improving the surgical effect.

[0031] like Figures 1-4 As shown, the top of the handle 1 is equipped with an adjustment mechanism 5 for pushing the mechanism 4. The adjustment mechanism 5 includes a threaded disc 501 fixedly connected to the top of the push base 401. A connecting post 502 is fixedly connected to the center of the top of the threaded disc 501. An adjustment wheel 503 is fixedly connected to the top of the connecting post 502. The threaded disc 501 is threadedly connected to the first threaded hole 12. When it is necessary to adjust the elastic force of the third spring 404, that is, the pushing force of the top post 403, the adjustment wheel 503 is rotated, thereby driving the connecting post 502 to rotate, thereby driving the threaded disc 501 to rotate on the first threaded hole 12, thereby driving the threaded disc 501 to rise or fall, thereby realizing the adjustment of the elastic force of the third spring 404. The surgeon can adjust the appropriate force of the top post 403 according to the bone thickness below the bleeding point and the degree of osteoporosis of the patient, thereby improving the surgical effect.

[0032] like Figures 1-9As shown, the bottom end of the handle 1 is provided with a delivery mechanism 6, which includes a delivery tube 601. The top of the outer wall of the delivery tube 601 is provided with a third threaded groove 602. The delivery tube 601 is threadedly connected to the inner wall of the fixing seat 2 through the third threaded groove 602. Multiple fixing teeth 603 are fixedly connected to the bottom end of the delivery tube 601, and a buckle 604 is fixedly connected to the center of the inner wall of the delivery tube 601. When delivering hemostatic bone wax, the bottom end of the delivery tube 601 is aligned with the bleeding point on the bone surface, and the multiple fixing teeth 603 are used to fix it to the bone surface to prevent the delivery tube from falling off during the delivery process. The offset of 601 allows for precise targeting of the bleeding point, enabling the hemostatic bone wax to be delivered in one go, thus improving surgical efficiency. The clip 604 prevents the filling component 7 from falling off. Since the delivery tube 601 of the first filling mechanism 71, the second filling mechanism 72, and the third filling mechanism 73 have the same structure, when changing different filling components 7, the delivery tube 601 can be rotated to separate the third threaded groove 602 from the second threaded groove 21, thereby removing the delivery tube 601. This facilitates the replacement of different filling components 7 and makes it convenient for use at different bony bleeding points.

[0033] like Figures 1-7 As shown, a filling component 7 is installed inside the delivery mechanism 6. The filling component 7 is a first filling mechanism 71. The first filling mechanism 71 includes a first pressure rod 711 disposed inside the delivery tube 601. A first push block 712 is fixedly connected to the top end of the first pressure rod 711, and a first pressure head 713 is fixedly connected to the bottom end of the first pressure rod 711. The outer wall of the first pressure head 713 has multiple notches 714. When delivering hemostatic bone wax, the top end of the first push block 712 is flush with the top end of the delivery tube 601, leaving a cavity between the bottom end of the first pressure head 713 and the bottom end of the delivery tube 601. At this time, the surgeon will apply the hemostatic bone wax. When the hemostatic bone wax is placed into the cavity, its adhesiveness prevents the first pressure rod 711 from sliding downwards. When multiple fixing teeth 603 are fixed on the bone surface, and under the push of the cylinder 306, the first push block 712 and the first pressure rod 711 are pushed, thereby causing the first pressure head 713 to quickly squeeze out the hemostatic bone wax, thus firmly pressing it onto the bleeding point. The hemostatic bone wax fills the bleeding point under pressure, and excess hemostatic bone wax will be discharged upwards along multiple notches 714 to prevent excessive bone wax at the bleeding point on the bone surface. Furthermore, the bottom of the first pressure head 713 is designed with a 0-degree angle to fit the bleeding point of the bone structure at the corresponding angle.

[0034] like Figures 1-8As shown in Embodiment 2: Based on Embodiment 1, the filling component 7 is a second filling mechanism 72. The second filling mechanism 72 includes a second pressure rod 721. The top of the second pressure rod 721 is fixedly connected to a second push block 722, and the bottom of the second pressure rod 721 is fixedly connected to a second pressure head 723. Similarly, when multiple fixing teeth 603 are fixed on the bone surface, and under the push of the cylinder 306, the second push block 722 and the second pressure rod 721 are pushed, thereby driving the second pressure head 723 to quickly squeeze out hemostatic bone wax, thus firmly pressing it on the bleeding point. The hemostatic bone wax fills the hemostatic point under pressure, and the bottom of the second pressure head 723 is designed at 60 degrees, thus fitting the bleeding point of the bone structure at the corresponding angle.

[0035] like Figures 1-9 As shown in Embodiment 3: Based on Embodiment 1, the filling component 7 is a third filling mechanism 73. The third filling mechanism 73 includes a third pressure rod 731. The top of the third pressure rod 731 is fixedly connected to a third push block 732, and the bottom of the third pressure rod 731 is fixedly connected to a third pressure head 733. Similarly, when multiple fixing teeth 603 are fixed on the bone surface, and under the push of the cylinder 306, the third push block 732 and the third pressure rod 731 are pushed, thereby driving the third pressure head 733 to quickly squeeze out hemostatic bone wax, thus firmly pressing it on the bleeding point. The hemostatic bone wax fills the hemostatic point under pressure, and the bottom of the third pressure head 733 is designed at 30 degrees, thus fitting the bleeding point of the bone structure at the corresponding angle.

[0036] The working principle of this embodiment is as follows: First, the surgeon adjusts the appropriate force of the top column 403 according to the bone thickness below the bleeding point and the degree of osteoporosis of the patient, and rotates the adjusting wheel 503, thereby driving the connecting column 502 to rotate, thereby driving the threaded disc 501 to rotate on the threaded hole 12, thereby driving the threaded disc 501 to rise or fall, thereby adjusting the elastic force of the third spring 404. Based on the bleeding point in the bony structure at a 0-degree angle, the first filling mechanism 71 is selected. At this time, the first filling mechanism 71 is already installed at the bottom of the fixation seat 2. Before delivering the hemostatic bone wax, the top of the first pusher 712 is aligned with the top of the delivery tube 601, leaving a cavity between the bottom of the first pressure head 713 and the bottom of the delivery tube 601. The surgeon then places the hemostatic bone wax into the cavity. Due to the adhesiveness of the hemostatic bone wax, it prevents the first pressure rod 711 from sliding downward. The surgeon then holds the handle 1 to drive the delivery tube 601 into the operating channel, causing multiple fixing teeth 603 to be fixed on the bone surface, aligning the delivery tube 601 with the bleeding point. The surgeon then pushes the handle 1 forcefully, causing the top of the conical groove 14 to compress the first spring 304, causing the first spring 304 to contract. At the same time, the first mounting groove 13, the conical groove 14, and the positioning groove 15 move upward, causing the top of the movable column 303 to press against the pusher seat 4. The bottom of 01 is not inserted into the round hole 402. When the handle 1 continues to move downward, the push seat 401 squeezes the top third spring 404. At the same time, the top of the positioning column 302 slowly inserts into the positioning groove 15. When the positioning column 302 is fully inserted into the positioning groove 15, the positioning column 302 is in a straight position, which drives the movable column 303 to straighten. The straightened movable column 303 is inserted into the round hole 402. Under the action of the third spring 404, the push seat 401 is reset, which drives the top column 403 to move downward quickly, which pushes the column 306. Under the push of the column 306, the first push block 712 and the first pressure rod 711 are pushed, which drives the first pressure head 713 to quickly squeeze out the hemostatic bone wax, which is then firmly pressed on the bleeding point. The hemostatic bone wax fills the hemostatic point under pressure. Excess hemostatic bone wax will be discharged upward along the multiple notches 714 to prevent excessive bone wax at the bleeding point of the bone surface. The patient has a bleeding point in the bony structure at a 60-degree angle. The second filling mechanism 72 is selected. The delivery tube 601 is rotated so that the third threaded groove 602 is separated from the second threaded groove 21, thereby removing the first filling mechanism 71. Since the delivery tube 601 of the first filling mechanism 71 and the second filling mechanism 72 have the same structure, when installing the second filling mechanism 72, the delivery tube 601 can be installed at the bottom of the fixing seat 2. Similarly, when multiple fixing teeth 603 are fixed on the bone surface, and under the push of the cylinder 306, the second push block 722 and the second pressure rod 721 are pushed, thereby driving the second pressure head 723 to quickly squeeze out the hemostatic bone wax, thereby firmly pressing it on the bleeding point. The hemostatic bone wax fills the bleeding point under pressure. The patient has a bleeding point on a bony structure at a 30-degree angle. The third filling mechanism 73 is selected. Similarly, the delivery tube 601 of the first filling mechanism 71 and the third filling mechanism 73 has the same structure. When installing the third filling mechanism 73, the delivery tube 601 is installed at the bottom of the fixing seat 2. Similarly, when multiple fixing teeth 603 are fixed on the bone surface, and under the push of the cylinder 306, the third push block 732 and the third pressure rod 731 are pushed, thereby driving the third pressure head 733 to quickly squeeze out the hemostatic bone wax, thus firmly pressing it on the bleeding point. The hemostatic bone wax fills the bleeding point under pressure.
