Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a water injection accessory for a drill handle and a drill grinding device. Background Technology
[0002] In minimally invasive surgery, a grinding device is used to grind bone tissue. During this process, the surgeon holds the handle of the grinding device and extends the grinding head to the patient's bone tissue. High temperatures are generated during grinding, and cooling measures are necessary to prevent tissue damage. For grinding tools with an outer sheath, a water channel can be integrated into the sheath or between the sheath and the tool shank to deliver cooling water to the tip of the grinding tool, thus cooling the bone tissue.
[0003] However, for grinding tools without a sheath, the entire tool rotates during the procedure, making it difficult to integrate a water injection channel. Currently, doctors use a syringe to intermittently inject water for cooling, and the grinding tool handle needs to be paused during the water injection process. This is cumbersome and carries the risk of injuring the patient. In addition, the water injection process pauses the grinding procedure, which prolongs the operation time. Utility Model Content

Detailed Implementation
[0029] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0030] It should be understood that this invention can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this invention to those skilled in the art. In the drawings, the same reference numerals denote the same components throughout.
[0031] See Figure 2 The water-filling accessory 20 of this utility model is used for the grinding handle 10, which is used to connect and drive the grinding tool 11. It includes a handle body 13 and a support accessory 12 connected to the front end of the handle body 13. The support accessory 12 is provided with a support channel (not shown) for passing through and supporting the grinding tool 11.
[0032] The water injection accessory 20 is detachably attached to the support accessory 12 of the drill handle 10.
[0033] It should be noted that the water injection attachment 20 is installed on the support attachment 12 during use and can be used simultaneously with the grinding tool 11. That is, while performing grinding operations on the tissue, water injection attachment 20 is used to inject water for cooling. The use of water injection attachment 20 simplifies the cooling operation and does not prolong the operation time. Since the water injection attachment 20 is detachable, on the one hand, the doctor can choose whether to install the water injection attachment 20 according to the needs of the operation. On the other hand, the water injection attachment can be removed and cleaned separately after the operation, without having to clean the handle body and the water injection attachment together, which helps to avoid water entering the handle body.
[0034] It should also be noted that during surgery, the surgeon's hand holds the handle body 13, while the support attachment 12 acts as the grinding tool 11. The support attachment 12 ensures the coaxiality of the front and rear ends of the grinding tool, and in particular, reduces vibration during rotation of the slender tool. In this invention, because the water injection attachment is attached to the support attachment 12 rather than the handle body 13, the addition of the water injection attachment will not affect the intraoperative operation.
[0035] In some embodiments, the detachable water-filling accessory 20 of the drill handle 10 further includes:
[0036] Water injection pipe 21 has a water injection channel that runs through both ends, with the two ends of the water injection pipe 21 being an inlet 23 and an outlet 221, respectively.
[0037] Mounting component 24 is fixedly connected to the water injection pipe 21. The mounting component 24 is used to detachably install the water injection pipe 21 on one side of the outer periphery of the support accessory 12, so that the water outlet 221 of the water injection pipe 21 faces the cutting head of the corresponding grinding tool 11.
[0038] for example, Figure 1 and Figure 2As shown, the water injection accessory 20 is detachably mounted on the support accessory 12 via the mounting part 24. Depending on the specific surgical needs, the water injection accessory 20 can be installed or not. After the water injection accessory 20 is installed on the support accessory 12, during actual use, the peristaltic pump can be connected to the water inlet 23 to pump coolant into the water injection accessory 20. The coolant flows from the water inlet 23 through the water injection channel and out through the water outlet 221, which is aligned with the grinding tool 11. The coolant can cool the high temperature generated by the grinding tool 11 during the grinding process.
[0039] In some embodiments, the water injection pipe 21 includes a pipe body and a water injection connector 22, with the water inlet 23 formed on the water injection connector 22, which is used to connect to a water supply hose. For example, Figure 1 As shown, the water inlet connector 22 allows for quick and easy connection between the water inlet 23 and the water supply hose of the peristaltic pump, making the use of the water inlet accessory 20 more convenient and faster.
[0040] In some embodiments, the water injection pipe 21 includes a main pipe section 211 and a first pipe section 212. The water inlet 23 is located at the end of the first pipe section 212 away from the main pipe section 211. The first pipe section 212 is bent relative to the main pipe section 211 so that when the water injection accessory 20 is installed on the support accessory 12, the portion of the first pipe section 212 connected to the main pipe section 211 is relatively close to the drill handle 10, and the end of the first pipe section 212 with the water inlet 23 is relatively far away from the drill handle 10.
[0041] In the specific implementation process, such as Figure 1 and Figure 2 As shown, after the water injection accessory 20 is installed on the drill handle 10, the first pipe section 212 bends toward the side away from the drill handle 10, that is, bends toward the outside of the drill handle 10, so that the water inlet 23 and the water supply hose are not obstructed by the drill handle 10 when they are connected or disconnected, and the drill handle 10 is not affected by the water injection pipe 21 when it is used in the operation.
[0042] In some embodiments, the water injection pipe 21 includes a main pipe section 211 and a second pipe section 213. The water outlet 221 is located at the end of the second pipe section 213 away from the main pipe section 211. The second pipe section 213 is bent relative to the main pipe section 211 so that when the water injection accessory 20 is installed on the support accessory 12, the water outlet 221 is aligned with the grinding head of the corresponding grinding tool 11. For example, Figure 1 and Figure 2 As shown, after the water injection accessory 20 is installed on the support accessory 12, the second pipe section 213 is bent toward the grinding tool 11 so that the water outlet 221 is aligned with the grinding position of the grinding tool 11 to ensure the cooling effect.
[0043] In some embodiments, the mounting member 24 includes a first mounting portion 241 and a second mounting portion connected together. The first mounting portion 241 is fitted onto or holds the water inlet pipe 21, and the second mounting portion is fitted onto or holds the support attachment 12. For example, Figure 1 As shown, the first mounting part 241 is used to fix the water injection pipe 21, and the second mounting part is sleeved or held on the drill handle 10, and can be detachably fixed on the drill handle 10, so that the water injection accessory 20 can be detachably fixed on the drill handle 10.
[0044] In some embodiments, the mounting member 24 includes at least two elastic clamping pieces 242 connected to the water injection pipe 21. The at least two elastic clamping pieces 242 are arranged opposite each other to form a clamping space 243 into which the support attachment 12 is inserted, so that each elastic clamping piece 242 can wrap around the support attachment 12. For example, Figure 1 As shown, the first mounting part of the mounting component 24 includes two elastic clamping pieces 242. During installation, the two elastic clamping pieces 242 can adaptively wrap around the support attachment 12 through elastic deformation and be fixed by elastic action, so that the water injection attachment 20 can be detachably fixed on the support attachment 12. This method makes the installation and removal process of the water injection attachment 20 convenient and quick.
[0045] Figure 1 In the example shown, the elastic clamping pieces 242 are all arc-shaped pieces. In actual implementation, the shape of the elastic clamping pieces 242 can also be a bent piece, or it can have both a bent part and an arc part. As long as it can adapt to deformation during disassembly and assembly, the water injection accessory 20 can be detached.
[0046] In some embodiments, the mounting member 24 further includes a first elastic mounting portion integrally formed with each of the elastic clamping pieces 242. The first elastic mounting portion is sheet-like and has a deformable groove 244 for engaging the water injection tube 21. The deformable groove 244 communicates with the clamping space 243. This structure allows the water injection tube 21 to be detachably mounted in the deformable groove 244, enabling the selection of an appropriate length of water injection tube 21 according to surgical needs, and then the water injection accessory to be clamped onto the support accessory 12 using the elastic clamping pieces 242.
[0047] for example, Figure 1 As shown, the integrated structure of each elastic clamping piece 242 facilitates the production and manufacturing of the mounting piece 24, and the variable groove facilitates the fixed connection between the water injection pipe 21 and the mounting piece 24.
[0048] This embodiment also provides a drill handle 10, such as Figure 2 As shown, it is compatible with water injection accessory 20 and includes:
[0049] A grinding handle 10 is used to connect to and drive a grinding tool 11. The grinding handle 10 includes a handle body 13 and a support attachment 12 connected to the front end of the handle body 13. The support attachment 12 is provided with a support channel (not shown) for passing through and supporting the grinding tool 11.
[0050] Water injection accessory 20, wherein the water injection accessory 20 is any one of the water injection accessories described above.
[0051] The support accessory 12 can be detachably connected to the handle body 13, or it can be non-detachably connected.
[0052] The grinding drill handle of this utility model has a water injection attachment attached to the support attachment of the grinding drill handle. The water injection attachment on the support attachment can continuously inject water into the tissue to be ground during the operation, so that the doctor can continuously cool the grinding area without pausing the operation, which can shorten the operation time and reduce the surgical risk. Moreover, because the water injection attachment is detachably attached to the support attachment, the water injection attachment can be removed and cleaned separately, without having to clean the handle body and the water injection attachment together, which helps to prevent water from entering the handle body.
[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
