Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a shoulder joint glenoid locator. Background Technology

[0002] In shoulder surgery, accurate localization of the glenoid cavity is crucial for surgical success. Currently, there is a lack of specialized instruments for precise and efficient glenoid cavity localization in shoulder surgery. Surgeons often rely on experience and traditional localization methods, which not only increases the difficulty and risk of the surgery but may also lead to inaccurate localization and affect the surgical outcome.

[0003] Currently, in shoulder joint surgery, due to the lack of specialized glenoid locators, positioning mainly relies on the doctor's experience and visual inspection, which is not accurate enough and prone to errors. Moreover, the operation requires multiple steps and tools to work together, which is quite complicated and increases the operation time and complexity. At the same time, the existing positioning methods cannot be fixed well in the glenoid region, and displacement is prone to occur during the operation. Utility Model Content

[0004] The main objective of this invention is to provide a glenoid locator for shoulder joints, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A glenoid locator for shoulder joints includes an arc-shaped locator body. The arc-shaped locator body has a first hollow groove inside. A wire block is fixedly connected to the left side of the outer surface of the arc-shaped locator body. A guide wire is threaded through the wire block. An L-shaped barb is fixedly connected to one end of the arc-shaped locator body. A second hollow groove is opened inside the L-shaped barb. A connecting block is fixedly connected to the other end of the arc-shaped locator body. A sleeve is inserted and fixedly connected to the left end of the connecting block.

[0007] Preferably, the inner wall of the first hollow groove is smoothed.

[0008] By adopting the above technical solution, the smoothing of the inner wall of the first hollow groove reduces the frictional resistance of the guidewire, making its movement smoother. This improves the operational accuracy and efficiency of the positioner, providing better assurance for positioning operations during shoulder joint surgery and contributing to the smooth progress of the surgery.

[0009] Preferably, the length of the L-shaped barb is 1 cm to 2 cm.

[0010] By adopting the above technical solution, the position of the fixator in the glenoid cavity of the shoulder joint can be effectively assisted, preventing displacement. This ensures the stability of the positioning without excessively interfering with the surgical procedure, providing strong support for the precise execution of the surgery.

[0011] Preferably, the guide wire can slide freely within the guide block, the L-shaped barb, and the sleeve.

[0012] By adopting the above technical solution, this design allows the guidewire to flexibly reach the surgical site, providing the surgeon with precise positioning guidance. This improves the accuracy and efficiency of positioning, reduces the difficulty of the surgical procedure, and contributes to the smooth progress of the surgery.

[0013] Preferably, the connection between the conductor block and the arc-shaped positioner body is welding.

[0014] By adopting the above technical solution, the connection is ensured to be firm, and the lead block is not easy to separate from the arc-shaped locator body during the operation, which ensures the stability of the locator and helps to improve the accuracy and reliability of surgical positioning.

[0015] Preferably, the connecting block is integrally formed with the arc-shaped locator body.

[0016] By adopting the above technical solution, this design enhances the strength and stability of the connection, preventing loosening during surgery and ensuring a reliable connection between the sleeve and the arc-shaped positioner body, which is beneficial for the positioner to function better as a whole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0019] 2. In this invention, traditional positioning methods require multiple steps and tools working together, while this device integrates multiple functions into one unit. It eliminates the need for complex tool combinations and cumbersome operating procedures, reducing surgical time and complexity, and improving surgical efficiency.

[0020] 3. In this invention, the L-shaped barb and the arc-shaped locator body are designed to better fix the device in the glenoid region of the shoulder joint, effectively preventing displacement during surgery. This ensures accurate and stable positioning during the procedure, providing a strong guarantee for surgical success. Attached Figure Description

[0029] A glenoid locator for shoulder joint includes an arc-shaped locator body 1, with a first hollow groove 2 inside the arc-shaped locator body 1. A wire block 3 is fixedly connected to the left side of the outer surface of the arc-shaped locator body 1, and a guide wire 4 is threaded through the wire block 3. An L-shaped barb 5 is fixedly connected to one end of the arc-shaped locator body 1, with a second hollow groove 6 inside the L-shaped barb 5. A connecting block 7 is fixedly connected to the other end of the arc-shaped locator body 1, and a sleeve 8 is inserted and fixedly connected to the left end of the connecting block 7.

[0030] The above scheme involves an arc-shaped locator body 1 designed according to the physiological curve of the glenoid fossa, fitting snugly against the glenoid fossa during use. The internal first hollow groove 2 provides space for the guide wire 4 to pass through, while also helping to reduce the overall weight of the locator. A guide wire block 3 located on the left side of the outer surface of the arc-shaped locator body 1 secures the guide wire 4, allowing it to move accurately along a predetermined path. The guide wire 4 can pass through the guide wire block 3 and further extend into the L-shaped barb 5 and the sleeve 8. The L-shaped barb 5 helps to fix the locator to the glenoid fossa, preventing displacement during surgery. The second hollow groove 6 within the L-shaped barb 5 may also provide an additional path for the guide wire 4. A connecting block 7 connects the arc-shaped locator body 1 to the sleeve 8, which can be used in conjunction with other surgical instruments to facilitate surgical procedures.

[0031] In this embodiment, the inner wall of the first hollow groove 2 is smoothed; the length of the L-shaped barb 5 is 1 cm to 2 cm; the guide wire 4 can slide freely in the guide wire block 3, the L-shaped barb 5 and the sleeve 8; the guide wire block 3 is connected to the arc-shaped locator body 1 by welding; the connecting block 7 is integrally formed with the arc-shaped locator body 1.

[0032] Through the above scheme: the inner wall of the first hollow groove 2 is smoothed, which reduces the frictional resistance of the guide wire 4 when it passes through it, allowing the guide wire 4 to move more smoothly and facilitating the positioning operation; the L-shaped barb 5 is 1 cm to 2 cm long, which can help fix the locator to the glenoid fossa during the positioning process, preventing it from shifting during the operation and ensuring the stability of the positioning; the guide wire 4 can slide freely within the guide block 3, the L-shaped barb 5 and the sleeve 8, accurately pointing to the part that needs to be positioned, providing the surgeon with precise positioning instructions; the guide block 3 and the arc-shaped locator body 1 are connected by welding, ensuring the firmness of the guide block 3 during the operation and preventing it from easily separating from the arc-shaped locator body 1, thus ensuring that the guide wire 4 can move stably on the predetermined path; the connecting block 7 is integrally formed with the arc-shaped locator body 1, enhancing the strength and stability of the connection, making the connection between the sleeve 8 and the arc-shaped locator body 1 more reliable, and facilitating the operation in conjunction with other surgical instruments.

[0033] It should be noted that this utility model is a glenoid locator for the shoulder joint. During use, firstly, when performing shoulder joint surgery, the arc-shaped locator body 1 is placed against the corresponding position of the glenoid fossa. The arc-shaped locator body 1 is designed according to the physiological curve of the glenoid fossa, which better adapts to the surgical site and provides a stable foundation for subsequent positioning operations. The first hollow groove 2 inside the arc-shaped locator body 1 provides space for the guide wire 4 to pass through, while also reducing the weight of the locator, making it lighter and more flexible during use. The inner wall of the first hollow groove 2 is smoothed to reduce the frictional resistance when the guide wire 4 passes through it, ensuring smooth movement of the guide wire 4. The guide wire block 3 is used to guide and fix the guide wire 4, allowing it to move accurately along a predetermined path. The guide wire 4 passes through the guide wire block 3 and can slide freely within the guide wire block 3, the L-shaped barb 5, and the sleeve 8. This design allows the guide wire 4 to flexibly reach the area requiring positioning, providing the surgeon with precise positioning instructions. The other end of the arc-shaped locator body 1 is connected to the sleeve 8 via an integrally formed connecting block 7. The integrated design of the connecting block 7 and the arc-shaped locator body 1 ensures the firmness and stability of the connection, avoiding loosening or separation during the operation.
