Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a suction bone curette. Background Technology

[0002] A medical curette is a surgical instrument, mainly composed of a handle and a scraping blade. It is used to scrape away diseased tissue, residues, or foreign objects during surgery, such as cleaning the alveolar bone after tooth extraction. Medical curettes are designed in various ways to adapt to different surgical sites and needs. They are an important auxiliary tool for doctors to perform surgical operations. In order to facilitate the cleaning of scraped debris and affected areas, a suction bone curette is needed.

[0003] A search revealed Chinese Patent Publication No. CN219000864U, which discloses an otological suction curette, comprising a curette body, a curette head, and a curette tube. The curette body has an inner cavity, and the curette head has a collection chamber communicating with the inner cavity. The curette tube is located within the inner cavity and has an exposed end that passes through the curette body, which is used to connect to a negative pressure suction device. This otological suction curette, by incorporating a curette tube within the curette body and a collection chamber in the curette head, collects lesions or bone tissue scraped off during ear surgery within the collection chamber, which is then directly suctioned away by the negative pressure curette tube, promptly cleaning lesions and maintaining a clear surgical field. However, in actual use, while the device uses an inner liner to prevent impurities from clogging the curette tube, impurities can still clog the liner and the inside of the curette. Furthermore, the non-removable curette is difficult to completely remove impurities through rinsing, leading to cumbersome cleaning and maintenance, thus reducing the reliability of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a suction bone scraper, which aims to improve the problem of difficulty in cleaning scrapers after they become internally clogged in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bone scraper for suction, including a flexible tube interface, a suction tube connected to the left side of the flexible tube interface, a protective ring rotatably connected to the left side of the suction tube, a tapered tube fixedly connected to the outer side of the protective ring, slot blocks fixedly connected to the outer rear side of the tapered tube, a threaded groove rotatably connected to the left side of the tapered tube, a suction head provided on the outer side of the threaded groove, a threaded ring threadedly connected to the inner side of the threaded groove, an inner liner plate rotatably connected to the left side of the threaded ring, and insertion rods fixedly connected to the front and rear sides of the outer side of the inner liner plate. The outer side of the insertion rod passes through the suction head and engages with the slot block. An arc-shaped blade is fixedly connected to the top of the suction head, and an angle adjustment mechanism is provided on the outer side of the suction tube for adjusting the angle of the suction head.

[0006] The above technical solution allows for the following: by rotating the threaded ring on the conical block, the inner threaded ring and inner liner plate, along with the insertion rod, can be driven to move together. After the insertion rod moves, it will be disengaged from the slot block, and as the threaded groove rotates, the connection with the threaded ring will also be released. At this point, the suction head can be easily removed for cleaning. During use, impurities are removed by suction through the hose interface. The inner liner plate design on the inside of the suction head can effectively prevent impurities from clogging the suction tube. In addition, by disassembling and assembling the suction head, it is convenient to clean and maintain its interior.

[0007] As a further description of the above technical solution: The angle adjustment mechanism includes a sealing plate. The top of the suction tube is fixedly connected to the sealing plate and a belt. Rotating wheels are rotatably connected to the left and right sides of the top of the suction tube. The two rotating wheels are connected to each other by the belt drive. A gear is fixedly connected to the top of the left rotating wheel. A toothed groove is opened on the outer side of the protective ring. The toothed groove is meshed with the gear.

[0008] The above technical solution allows for the removal of impurities through suction via a flexible tube interface. The inner lining of the suction head effectively prevents blockages. By rotating the right-side wheel of the device, a belt drive mechanism synchronously drives the left-side wheel and gear to rotate. The user can easily control the left-side wheel, which is inserted into the body, simply by operating the right side of the device. The rotation of the gear meshes and drives the protective ring and tapered tube to rotate together, allowing for flexible adjustment of the angle and position of the suction head according to surgical needs, greatly facilitating surgical operations.

[0009] As a further description of the above technical solution: A knob is rotatably connected to the top right side of the sealing plate, and the bottom of the knob passes through the sealing plate and is fixedly connected to the rotating wheel on the right side.

[0010] The above technical solution allows the right-side rotating wheel connected to it to rotate synchronously by turning the knob.

[0011] As a further description of the above technical solution: The top right side of the sealing plate has multiple indicator slots, and the front side of the knob is fixedly connected to an indicator block.

[0012] The above technical solution allows us to observe the indicator groove on the indicator block as the knob is rotated, thus determining the current rotation angle of the knob.

[0013] As a further description of the above technical solution: Positioning blocks are fixedly connected to the upper and lower sides of the right end of the hose interface, and positioning holes are provided on the outer side of the positioning blocks.

[0014] The above technical solution allows for convenient storage of the device through the positioning hole, and also facilitates the fixing of the suction device at the hose interface.

[0015] As a further description of the above technical solution: A connection port is provided on the left side of the hose interface, and a conduit is fixedly connected to the inside of the connection port.

[0016] The above technical solution allows impurities to easily enter the hose interface from the suction tube via the conduit inside the connection port.

[0017] As a further description of the above technical solution: The outer side of the plug rod has a groove, and a locking block is fixedly connected to the outer side of the groove.

[0018] The above technical solution, through the limiting of the locking block in the groove, can prevent the plug rod from retracting into the suction head and becoming difficult to remove when the suction head is being removed.

[0019] As a further description of the above technical solution: A sealing ring is rotatably connected to the outer side of the protective ring, and the sealing ring is fixedly connected to the suction tube.

[0020] The above technical solution uses a sealing ring to block multiple grooves on the outside of the protective ring, preventing contaminants from entering the interior during surgery and making them difficult to clean.

[0021] This utility model has the following beneficial effects: 1. In this utility model, by rotating the threaded groove on the tapered tube, the inner threaded ring and inner liner plate and the plug rod are moved. After the plug rod moves, it is released from the fixation with the slot block and is released from the connection with the threaded ring as the threaded groove rotates. The suction head can then be removed for cleaning. During use, impurities are sucked out through the hose interface. The inner liner plate on the inside of the suction head can prevent impurities from clogging the suction tube. The suction head can be disassembled and assembled to facilitate internal cleaning and maintenance, thereby improving the reliability of the device.

[0022] 2. In this utility model, impurities are suctioned out using the hose interface during use. The suction head liner prevents blockage. Rotating the right rotating wheel synchronously drives the left rotating wheel and gear to rotate via belt transmission. The user can control the left rotating wheel inserted into the body by operating the right side of the device. The gear rotation meshes and drives the protective ring and conical tube to rotate. The angle and position of the suction head can be adjusted according to needs to facilitate operation during surgery, thereby improving the practicality of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a bone scraper, including a flexible tube interface 1, a suction tube 5 connected to the left side of the flexible tube interface 1, a protective ring 6 rotatably connected to the left side of the suction tube 5, a tapered tube 7 fixedly connected to the outside of the protective ring 6, slot blocks 8 fixedly connected to the front and rear sides of the tapered tube 7, a threaded groove 9 rotatably connected to the left side of the tapered tube 7, a suction head 15 provided on the outside of the threaded groove 9, a threaded ring 10 threadedly connected to the inside of the threaded groove 9, an inner liner plate 11 rotatably connected to the left side of the threaded ring 10, a plug rod 12 fixedly connected to the front and rear sides of the inner liner plate 11, the plug rod 12 passes through the suction head 15 and engages with the slot block 8, an arc-shaped blade 16 fixedly connected to the top of the suction head 15, and an angle adjustment mechanism 2 provided on the outside of the suction tube 5 for adjusting the angle of the suction head 15. Specifically, by rotating the threaded groove 9 on the tapered tube 7, the inner threaded ring 10 is rotated through the meshing connection. As the threaded ring 10 rotates, the inner liner 11 and the plug rod 12 on it will move left and right along the right side of the suction head 15. When the plug rod 12 moves to the point where it is released from the insertion and fixation of the slot block 8 and disengages from the threaded ring 10 at the same time as the threaded groove 9 rotates, the suction head 15 can be removed from the tapered tube 7 for cleaning. When in use, impurities are sucked out through the hose interface 1. The inner liner 11 on the inner side of the suction head 15 can also effectively prevent impurities from clogging the suction tube 5.

[0027] Reference Figure 1 and Figure 4 The angle adjustment mechanism 2 includes a sealing plate 201. The top of the suction tube 5 is fixedly connected to the sealing plate 201 and the belt 204. Rotating wheels 203 are rotatably connected to the top left and right sides of the suction tube 5. The two rotating wheels 203 are connected to each other by the belt 204. The top of the left rotating wheel 203 is fixedly connected to the gear 202. The outer side of the guard ring 6 is provided with a toothed groove 205, which meshes with the gear 202. Specifically, rotating the right rotating wheel 203, through the transmission action of the belt 204, synchronously drives the left rotating wheel 203 and its gear 202 to rotate. In this way, the user only needs to operate the right side of the device to control the left rotating wheel 203 that is inserted into the patient's body. As the gear 202 rotates, it drives the protective ring 6 and its conical tube 7 to rotate through meshing, thereby adjusting the angle and position of the suction head 15 as needed.

[0028] Reference Figure 1 , Figure 4 and Figure 5 A knob 17 is rotatably connected to the top right side of the sealing plate 201. The bottom of the knob 17 passes through the sealing plate 201 and is fixedly connected to the right rotating wheel 203. Multiple indicator grooves 19 are provided on the top right side of the sealing plate 201. An indicator block 18 is fixedly connected to the front side of the knob 17. Positioning blocks 20 are fixedly connected to the upper and lower sides of the right end of the hose interface 1. Positioning holes 21 are provided on the outer side of the positioning blocks 20. Specifically, by rotating the knob 17, the rotating wheel 203 can be rotated synchronously. Rotating the knob 17 can also cause the indicator block 18 on it to move synchronously. At this time, by observing the indicator groove 19 indicated by the indicator block 18, the rotation angle of the suction head 15 can be observed. The positioning hole 21 on the positioning block 20 can facilitate the connection of the hose interface 1 to the suction device, and can also be stored conveniently when not in use.

[0029] Reference Figure 3 , Figure 4 and Figure 5A connection port 3 is provided on the left side of the hose interface 1, and a conduit 4 is fixedly connected to the inner side of the connection port 3; a groove 13 is provided on the outer side of the plug rod 12, and a locking block 14 is fixedly connected to the outer side of the groove 13; a sealing ring 22 is rotatably connected to the outer side of the protective ring 6, and the sealing ring 22 is fixedly connected to the suction tube 5. Specifically, through the conduit 4 inside the connection port 3, impurities that can be easily scraped off can be sent into the hose interface 1. Through the locking block 14 on the groove 13, the plug rod 12 can be prevented from falling completely into the suction head 15 and being difficult to remove as it contracts. Through the sealing ring 22, the toothed groove 205 on the protective ring 6 can be protected, thereby preventing blood and dirt from entering the toothed groove 205 during the operation.

[0030] Working principle: Before using the device, firstly, by rotating the threaded groove 9 along the tapered tube 7, the inner threaded ring 10 can be rotated through the meshing connection. At this time, as the threaded ring 10 rotates, the inner liner plate 11 and the plug rod 12 on it will move left and right along the right side of the suction head 15. When the plug rod 12 moves and is released from the plugging and fixing of the slot block 8, and is simultaneously released from the connection with the threaded ring 10 as the threaded groove 9 rotates, the suction head 15 can be removed from the tapered tube 7 for cleaning. In addition, when using the device to suck up impurities through the hose interface 1, the inner liner plate 11 inside the suction head 15 can also prevent impurities from clogging the suction tube 5. Furthermore, by rotating the right rotating wheel 203, the left rotating wheel 203 and its gear 202 can be driven to rotate synchronously through the transmission of the belt 204. This allows the user to operate the left rotating wheel 203 inserted into the patient's body by operating the right side of the device. At this time, as the gear 202 rotates, it will drive the guard ring 6 and its conical tube 7 to rotate through meshing. This allows the angle and position of the suction head 15 to be adjusted as needed by rotating the conical tube 7.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
