Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a punching positioner. Background Technology

[0002] Coracoid process displacement fixation is an effective surgical procedure for treating recurrent shoulder dislocations with severe glenoid defects. In 1954, Michael Latarjet described a surgical method involving osteotomy of the coracoid process, passing through the subscapularis muscle of the slit, and fixing it to the anteroinferior margin of the glenoid with a single screw. This surgical approach has been widely used in clinical practice and has been continuously improved and refined in subsequent research. In recent years, Lafosse proposed a fully arthroscopic surgical method, namely, using two cannulated screws for coracoid process displacement fixation, a method known as arthroscopic Latarjet surgery.

[0003] Arthroscopic Latarjet surgery is increasingly used in clinical practice due to its minimally invasive nature and excellent visualization. However, several challenges remain during the procedure. One common issue is coracoid process fracture, with previous literature reporting an intraoperative incidence of 1.2%-7%, which may be even higher given the structural characteristics of the coracoid process in Chinese individuals. Furthermore, the commonly used coracoid process screw or suture-button fixation methods, both domestically and internationally, cannot completely prevent coracoid process fractures. Therefore, using suture anchors for coracoid process displacement fixation has become a novel approach, aiming to reduce the incidence of coracoid process fractures and address the issue of screw fixation being unsuitable due to the small size of the coracoid process. Nevertheless, in practice, issues such as uneven and inconsistent drilling positions for the coracoid process persist, potentially leading to difficulties in suture crossing and coracoid process fixation during the procedure. Utility Model Content

[0004] The purpose of this application is to provide a drilling positioner that can improve the stability of the positioning drill bit, reduce the risk of slippage, and improve the drilling accuracy of the drill bit.

[0005] To achieve the above objectives, this utility model provides a punching locator, comprising:

[0006] A handle, the handle including a connecting end and a gripping end, the gripping end providing a gripping position;

[0007] The positioning head is connected to the connecting end. The positioning head is provided with a drill positioning hole, and the end face of the positioning head that abuts against the part to be drilled is provided with anti-slip texture.

[0008] In an optional implementation, the number of positioning holes is at least two.

[0009] In an optional embodiment, at least two of the positioning holes are arranged parallel to each other in the axial direction.

[0010] In an optional embodiment, the positioning head includes a first column and a second column, the diameter of the first column being smaller than the diameter of the second column, the first column and the second column being coaxially and fixedly connected to form a convex block structure of the positioning head, and the positioning hole penetrating the first column and the second column.

[0011] In an optional embodiment, the second column is provided with a mating hole, and the connecting end is installed at the mating hole of the second column.

[0012] In an optional embodiment, the connecting end is detachably connected to the second column;

[0013] The number of mating holes is at least two, and the connecting end is installed in one of the mating holes.

[0014] In an optional embodiment, the mating holes are spaced apart.

[0015] In an optional embodiment, the axis of the mating hole is inclined relative to the axis of the second column.

[0016] In an optional embodiment, the gripping end is hollowed out.

[0017] In an optional embodiment, the anti-slip texture includes patterns in at least two directions.

[0018] In this application, the anti-slip texture design increases the friction between the positioning head and the patient's drilling site, improving the stability of the positioning drill bit and reducing the risk of slippage. This helps avoid surgical complications such as coracoid process fractures, thereby reducing the risk of surgical failure.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] To facilitate smoother coracoid fixation during surgery, ensure more even distribution of sutures along the coracoid process, and achieve more stable fixation, thereby avoiding irreversible surgical failure due to intraoperative complications, embodiments of this application provide a drilling locator that helps the drill bit remain stable during drilling, ensuring a uniform and consistent drilling position along the coracoid process. This reduces the increased surgical difficulty caused by uneven suture distribution and the risk of surgical failure due to coracoid fracture.

[0030] Of course, it should be understood that the punching locator provided in the embodiments of this application can also be applied to other surgical sites, such as the femur or tibia. This application uses the application of the punching locator in coracoid surgery to illustrate the technical solution of this application, but it does not mean that this application is limited.

[0031] like Figure 1 and Figure 2 As shown, the punching locator includes a handle 100 and a locating head 200.

[0032] like Figure 1 As shown, the handle 100 includes a connecting end 110 and a gripping end 120. The connecting end 110 is connected to the positioning head 200. Moving the connecting end 110 causes the positioning head 200 to move. The gripping end 120 provides a gripping position. The doctor moves the connecting end 110 and the positioning head 200 by moving the gripping end 120.

[0033] The positioning head 200 is connected to the connecting end 110. The positioning head 200 is provided with a drill bit positioning hole 240, and the end face of the positioning head 200 that abuts against the part to be drilled is provided with anti-slip texture 250.

[0034] During use, firstly, a suitable location is selected at the patient's site to be drilled according to the surgical needs to obtain a pre-drilled hole. After determining the location of the pre-drilled hole, the doctor holds the grip end 120 and moves the connecting end 110 and the positioning head 200 through the grip end 120, thereby moving the positioning head 200 to the patient's site to be drilled. The anti-slip texture 250 can increase the friction between the positioning head 200 and the patient's site to be drilled, improve the stability of the positioning drill bit, and reduce the risk of slippage. This helps to avoid surgical complications such as coracoid process fracture, thereby reducing the risk of surgical failure.

[0035] Subsequently, the surgeon inserts the drill bit along the selected positioning hole 240 to begin precise drilling. Guided by the positioning hole 240, the drill bit ensures that each puncture accurately reaches the predetermined position and depth. After drilling, the surgeon carefully withdraws the positioning head 200 from the coracoid process to prepare for the subsequent coracoid process cutting step. In this application, the drill positioning hole 240 on the drilling locator ensures that the drill bit remains stable during drilling, maintaining a uniform and consistent drilling position on the coracoid process. This significantly reduces surgical difficulties caused by uneven suture flow during the operation and improves surgical precision.

[0036] During operation, the punching locator provided in the embodiments of this application ensures ease of operation, accuracy and repeatability, thereby improving surgical efficiency, reducing surgical time and reducing intraoperative risks.

[0037] For example, in this embodiment, the connection method between the connecting end 110 and the positioning head 200 can be at least one of the following: threaded connection, bolted connection, snap-fit ​​or welding, etc.

[0038] For example, in this embodiment, the anti-slip texture 250 can be a single straight line texture, an intersecting straight line texture, a curved texture, or a combination thereof.

[0039] To enhance the positioning head 200's ability to handle more complex surgical sites, such as Figure 1 and Figure 2 As shown, in one embodiment, the number of positioning holes 240 is at least two. When one of the positioning holes 240 is not suitable, the doctor can switch to another positioning hole 240, thereby providing the doctor with more options when performing surgery and improving the adaptability of the punching positioner.

[0040] Exemplarily, in one embodiment, two positioning holes 240 are provided. In another embodiment, three positioning holes 240 are provided. In yet another embodiment, as... Figure 1 and Figure 2 As shown, four positioning holes 240 are provided. In another embodiment, five positioning holes 240 are provided. Of course, in other embodiments, the number of positioning holes 240 can also be other, such as six, seven, or eight.

[0041] In this application, by providing multiple positioning holes 240, the surgeon can flexibly select the most suitable positioning hole 240 according to the actual situation during the operation. This is especially suitable for situations where the surgical site is complex or requires precise drilling, increasing the flexibility and operability of the operation.

[0042] In this application, different patients or different surgical sites of the same patient may have different anatomical structures and different surgical requirements. The design of multiple positioning holes 240 allows the punching locator to better adapt to these changes, improving the versatility and practicality of the locator.

[0043] In this application, when a surgeon finds that a certain positioning hole 240 is unsuitable for the current surgical needs, they can quickly switch to another positioning hole 240, avoiding surgical risks caused by inaccurate positioning. This helps ensure the safety of the surgery and the health of the patient.

[0044] In this application, the selection of multiple positioning holes 240 reduces the time the surgeon spends finding suitable drilling locations during the operation, thereby improving surgical efficiency. At the same time, accurate positioning also helps reduce uncertainty and errors during the operation, further shortening the operation time.

[0045] To further enhance the positioning head 200's ability to handle more complex surgical sites, in one embodiment, at least two positioning holes 240 are arranged parallel to each other in the axial direction, enabling the positioning head 200 to adapt to the surgical site. For example, in one embodiment, the positioning head 200 is provided with two positioning holes 240, which are arranged parallel to each other.

[0046] For example, in one embodiment, the positioning head 200 is provided with three positioning holes 240, namely the first hole, the second hole and the third hole. The axes of the first hole and the second hole are parallel to the axis of the positioning head 200, and the axis of the third hole is inclined relative to the axis of the positioning head 200. Thus, the axis of the third hole is inclined to the axis of the first hole and the axis of the second hole.

[0047] In this application, at least two positioning holes 240 are arranged parallel to each other in the axial direction, enabling the positioning head 200 to better adapt to complex surgical sites. This design allows surgeons to flexibly select different angles of the positioning holes 240 for drilling during surgery, based on the patient's specific anatomical structure and surgical needs, thereby improving the adaptability and flexibility of the surgery.

[0048] In this application, the parallel positioning holes 240 help doctors to more precisely control the position and direction of the perforation. In complex surgical sites, traditional vertical or parallel perforation methods may not meet the surgical needs.

[0049] To reduce the weight of the positioning head 200, allowing doctors to operate the punching positioner for longer periods, such as... Figure 2 As shown, in one embodiment, the positioning head 200 includes a first column 210 and a second column 220. The diameter of the first column 210 is smaller than the diameter of the second column 220. The first column 210 and the second column 220 are coaxially fixedly connected to form a positioning head 200 with a convex block structure, and the positioning hole 240 passes through the first column 210 and the second column 220.

[0050] For example, the first column 210 and the second column 220 are fixedly connected by welding, integral molding or bolt connection.

[0051] For example, in one embodiment, one of the positioning holes 240 is coaxially disposed on the first column 210 and the second column 220; but in another embodiment, the axes of all the positioning holes 240 are not coaxial with the axis of the first column 210 and the axis of the second column 220.

[0052] In this application, by designing the positioning head 200 as a convex block structure including a first column 210 and a second column 220, and with the diameter of the first column 210 being smaller than the diameter of the second column 220, the overall weight of the positioning head 200 can be effectively reduced while ensuring its strength and rigidity. This weight reduction helps doctors reduce arm and wrist fatigue during prolonged use of the perforation locator, thereby improving surgical precision and efficiency.

[0053] To achieve the connection relationship between the connecting end 110 and the second column 220, such as Figure 1 and Figure 2 As shown, in one embodiment, the second column 220 is provided with a mating hole 230, and the connecting end 110 is installed in the mating hole 230 of the second column 220. Exemplarily, the connecting end 110 is threaded into the mating hole 230 of the second column 220. In another embodiment, the connecting end 110 is snapped into the mating hole 230 of the second column 220. In another embodiment, the connecting end 110 is bonded to the mating hole 230 of the second column 220. In yet another embodiment, the connecting end 110 is welded to the mating hole 230 of the second column 220.

[0054] To further enhance the positioning head 200's ability to handle more complex surgical sites, such as Figure 1 As shown, in one embodiment, the connecting end 110 is detachably connected to the second column 220, and the number of mating holes 230 is at least two, with the connecting end 110 installed in one of the mating holes 230.

[0055] The detachable connection between the connecting end 110 and the second column 220 can be, for example, a threaded connection, a bolted connection, or a snap-fit ​​connection.

[0056] The connecting end 110 can be replaced with different mating holes 230 to improve adaptability.

[0057] For example, in one embodiment, the number of mating holes 230 is two. In another embodiment, the number of mating holes 230 is three. Of course, in other embodiments, the number of mating holes 230 may also be four, five, or six, etc.

[0058] In this application, by adjusting the position of the connecting end 110, the surgeon can ensure that the positioning head 200 maintains optimal positioning during surgery. This helps reduce surgical errors and improves the precision and safety of the surgery.

[0059] To enable the connecting end 110 to be installed at different locations on the second column 220, thus improving adaptability, such as... Figure 1 As shown, in one embodiment, the mating holes 230 are spaced apart.

[0060] For example, such as Figure 1 As shown, in one embodiment, two mating holes 230 are provided, and the two mating holes 230 are distributed at a 90-degree angle around the circumference of the second column 220. In another embodiment, three mating holes 230 are provided, and the three mating holes 230 are distributed at equal intervals around the circumference of the second column 220.

[0061] In this application, by spacing the mating holes 230 and selectively distributing them at different angles or equidistantly around the circumference of the second column 220, the connecting end 110 can be installed at different locations on the second column 220. This design significantly improves the adaptability and flexibility of the positioning head 200, enabling it to better adapt to the needs and limitations of different surgical sites. The surgeon can select the appropriate mating hole 230 to install the connecting end 110 according to the specific surgical situation to achieve optimal surgical results and positioning accuracy.

[0062] In this application, the spacing and circumferential distribution of the connecting holes 230 provide surgeons with more options and adjustment space. Before and during surgery, surgeons can quickly adjust the position and orientation of the connecting end 110 as needed, thereby simplifying the surgical procedure and improving surgical efficiency.

[0063] like Figure 1 As shown, in one embodiment, the axis of the mating hole 230 is tilted relative to the axis of the second column 220.

[0064] For example, in one embodiment, different mating holes 230 have different inclination angles relative to the axis of the second column 220.

[0065] In this application, the inclined arrangement of the axis of the mating hole 230 allows for more angle options during installation of the connecting end 110, thereby improving the flexibility and adaptability of the mechanical structure. This design enables the connecting end 110 to better adapt to different connection requirements and working conditions, enhancing the versatility and practicality of the mechanical structure.

[0066] To reduce the weight of the handle 100 and improve its dexterity, such as Figure 2 As shown, in one embodiment, the gripping end 120 is hollowed out.

[0067] In this application, the hollow design significantly reduces the overall weight of the handle 100, reducing hand fatigue during prolonged use or frequent movement of the handle 100, and improving ease of operation and comfort. The lightweight handle 100 makes the mechanical structure more portable and easier to operate, especially for devices that require prolonged handheld operation.

[0068] In this application, reducing weight not only improves ease of operation but also indirectly enhances the flexibility of the handle 100. The lighter handle 100 allows the operator to adjust the angle and force more freely during operation, thereby increasing the accuracy and response speed of the operation and reducing the probability of intraoperative errors.

[0069] In this application, the hollow design also helps dissipate heat from the handle 100. During prolonged use, heat from the doctor's hand can be transferred to the grip end 120, potentially causing heat buildup inside the handle 100. The hollow design provides more ventilation channels, helping to lower the temperature of the handle 100 and maintain a comfortable grip.

[0070] In one embodiment, the anti-slip texture 250 includes textures in at least two directions. Figure 2 The anti-slip texture 250 shown includes straight lines in one direction. In another embodiment, when the anti-slip texture 250 includes textures in at least two directions, the other texture may be relative to... Figure 2 The straight lines are angled. Of course, the anti-slip texture 250 can also be set as a closed or open curved shape, such as a circular line or a spiral line.

[0071] Therefore, in this application, the anti-slip texture 250 includes at least two straight-line textures, at least two curved textures, or at least one curved texture and at least one straight-line texture, or a combination thereof.

[0072] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
