Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a medical suture passer and surgical equipment. Background Technology
[0002] With the development of medical technology, the treatment methods for shoulder dislocation are constantly improving. The shoulder joint is one of the most flexible joints in the human body, and its wide range of motion makes it susceptible to dislocation. Recurrent anterior shoulder dislocation is a common orthopedic condition that affects the quality of life for many patients. Currently, the most commonly used surgical procedure for shoulder dislocation is the Latarjet procedure. This surgery enhances the stability of the shoulder joint by transplanting the coracoid process and its attached muscles. The core of the Latarjet procedure lies in fixing the coracoid process to the edge of the glenoid fossa to compensate for bone defects, thereby restoring the function and stability of the shoulder joint.
[0003] The use of suture anchors is a crucial technique in Latarjet surgery. These anchors are designed to fix the coracoid process to the edge of the glenoid fossa, achieving stable fixation of the bone fragment to the glenoid. Typically, two anchors are used to fix the bone fragment to the glenoid fossa during the procedure. Then, through a series of complex operations, the suture ends of these anchors are brought out to the surface of the transplanted coracoid process bone fragment and knotted to ensure a stable connection between the bone fragment and the glenoid. However, this process faces certain challenges in practice. Especially in situations with limited space in the shoulder joint, suture knots may occur during the suture passage or incorrect knotting between different suture ends during the knotting process. This not only significantly increases surgical time but may also lead to poor fixation, thus affecting the success rate of the surgery. Utility Model Content
[0004] The purpose of this application is to provide a medical suture guide and surgical device that can prevent anchor thread knots and improve surgical efficiency.
[0005] To achieve the above objectives, in a first aspect, this utility model provides a medical thread guide, comprising:

[0040] This application provides a medical suture guide 1000 and a surgical device. The surgical device includes the medical suture guide 1000 and a suture holder. A suture catcher 2000 is used in conjunction with the medical suture guide 1000. The surgeon uses the suture catcher 2000 to catch the sutures on the anchors and transfer them to the medical suture guide 1000. During surgery, more than one anchor is used, and multiple sutures are drawn from each anchor. These sutures are very prone to tangling and becoming disordered during surgery, thus affecting surgical efficiency. The medical suture guide 1000 facilitates the surgeon's suture management and improves surgical efficiency. The technical solutions for the medical suture guide 1000 and the surgical device are described in detail below.
[0041] In a first aspect, embodiments of this application provide a medical wire guide 1000, including a wire guide tube 100 and a separator 200.
[0042] like Figure 1 and Figure 2 As shown, the conduit 100 is hollow inside and open at both ends, and the internal space of the conduit 100 is a cable passage. The cable passage is used to pass the tail wire of the anchor.
[0043] like Figure 1 and Figure 2As shown, the separator 200 is disposed inside the conduit 100 along the axial direction of the conduit 100, and the separator 200 can be removed from or installed on the conduit 100.
[0044] like Figure 1 As shown, the separator 200 divides the wire passage channel into at least two sub-channels, each capable of passing through different anchor tail wires. Exemplarily, in one embodiment, the separator 200 divides the wire passage channel into two sub-channels. In another embodiment, the separator 200 divides the wire passage channel into three sub-channels. In yet another embodiment, the separator 200 divides the wire passage channel into four sub-channels. Of course, in other embodiments, the wire passage channel may also be divided into five, six, or seven sub-channels.
[0045] To illustrate the usage of the medical suture passer 1000 of this application in detail, assume that the patient needs two anchors during surgery, with sutures installed on the anchors, and four tail sutures leading out from each anchor. The separator 200 divides the suture passage into four suture sub-channels.
[0046] During use, the suture anchor is first correctly positioned and fixed to the glenoid fossa. Then, using a suture puller 2000, the eight sutures of the suture anchor are passed one by one through the pre-prepared bone holes in the coracoid process. The suture puller is moved near the coracoid process, ensuring that the opening of the suture tube 100 faces the location of the sutures. The operator uses a special suture puller 2000 of the appropriate diameter to pass through the suture channel, pulling out the two different tails of the proximal anchor from the proximal lateral space in sequence, and then pulling out the other two different tails of the proximal anchor from the proximal medial space. Following the same steps, the four tails of the distal anchor are pulled out from the distal lateral and medial sides through the suture tube 100 in sequence. After all the sutures have been successfully pulled through the suture puller, the operator manipulates the suture tube 100 to guide the cut coracoid bone fragment through the subscapularis muscle into the joint, ensuring it is close to the glenoid surface. Remove part of the structure of the separator 200, and tighten the two ends of the same suture of the proximal and distal anchors in sequence, and tie them respectively to form a fixation similar to "=" for the proximal and distal bone holes. Then remove the remaining structure of the separator 200, and tie the other two sutures of the proximal and distal anchors together to form a cross fixation similar to sewing on a button.
[0047] In summary, the advantages of the medical suture guide 1000 in this application are at least as follows: it makes suture management intuitive and orderly, significantly reducing surgical complexity that may result from suture tangling. Suture organization becomes clearer, greatly simplifying surgical procedures that could otherwise be cumbersome due to suture entanglement. The medical suture guide 1000, through its internal suture channels and removable dividers 200, divides sutures into different sub-channels, allowing surgeons to easily manage and organize multiple sutures emerging from multiple anchors. This avoids suture tangling and disordered order, thereby simplifying surgical procedures and improving surgical efficiency.
[0048] Using the medical suture guide 1000 of this application, doctors can handle sutures more intuitively and systematically, thus avoiding surgical complexity caused by tangled sutures. This makes the surgical process clearer and simpler, reducing the difficulty of the surgery. By managing sutures systematically, the medical suture guide 1000 reduces potential errors and oversights during surgery, thereby enhancing surgical safety. Doctors can manipulate sutures more accurately, ensuring the success of the surgery. The use of the medical suture guide 1000 makes suture management clearer, helping doctors make more accurate judgments and decisions during surgery. This helps improve the overall quality of the surgery and brings better treatment outcomes to patients.
[0049] In one embodiment, the suture tube 100 is a tube structure made of transparent material, allowing the operator to monitor the entire operation under a microscope and complete the surgery once everything is in order.
[0050] Transparent materials include, but are not limited to: glass, resin, transparent plastic, etc.
[0051] To enable doctors to better control the 100mm cannula, such as Figure 1 and Figure 2 As shown, in one embodiment, the medical wire guide 1000 further includes a handle 300, with a connecting end 310 and a gripping end 320 at its two ends, respectively. The connecting end 310 is connected to the wire guide tube 100, and the gripping end 320 provides a gripping position for the operator.
[0052] For example, the connection method between the connecting end 310 and the conduit 100 is, for example, a fixed connection or a detachable connection.
[0053] The medical suture device 1000 of this application is designed with a handle 300 suitable for the operator to hold. This allows for the retraction of the relatively developed muscle tissue in front of the glenoid fossa, and further, by the operator holding the handle 300, pushing and pulling the bone block to make it completely cover the glenoid fossa, and then tying a knot, which provides greater convenience and safety for the overall operation.
[0054] The 300-degree handle design allows surgeons to maintain a more comfortable operating posture during surgery, thereby improving surgical precision and efficiency and reducing patient risk.
[0055] To achieve the connection between the connecting end 310 and the conduit 100, such as Figure 2 As shown, in one embodiment, a connecting sleeve 330 is provided on the connecting end 310, and the connecting sleeve 330 is sleeved on the conduit 100. Exemplarily, the connecting sleeve 330 is fixedly connected to the conduit 100, and the fixed connection method includes, but is not limited to: threaded connection, welding, adhesive, snap-fit, or integral molding.
[0056] A stable mechanical connection can be formed by providing a connecting sleeve 330 on the connecting end 310 and fitting it onto the suture tube 100. This connection method ensures the stability and reliability of the handle 300 and the suture tube 100 during the operation and prevents operational errors caused by loose connection.
[0057] To reduce the weight of the handle 300 and improve its dexterity, such as Figure 3 As shown, in one embodiment, the gripping end 320 is hollowed out.
[0058] In this application, the hollow design significantly reduces the overall weight of the handle 300, reducing hand fatigue during prolonged use or frequent movement of the handle 300, and improving ease of operation and comfort. The lightweight handle 300 makes the mechanical structure more portable and easier to operate, especially for devices that require prolonged handheld operation.
[0059] In this application, reducing weight not only improves ease of operation but also indirectly enhances the flexibility of the handle 300. The lighter handle 300 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.
[0060] In this application, the hollow design also helps dissipate heat from the handle 300. During prolonged use, heat from the doctor's hand can be transferred to the grip end 320, and heat may accumulate inside the handle 300. The hollow design provides more heat dissipation channels, helping to reduce the temperature of the handle 300 and maintain a comfortable grip.
[0061] To achieve the connection between the separator 200 and the suture tube 100, in one embodiment, the separator 200 is detachably disposed within the suture tube 100. As the surgery progresses, the structure of the separator 200 is gradually disassembled to facilitate knotting of the sutures. Therefore, the separator 200 is detachably disposed on the suture tube 100, a design that facilitates disassembly of the separator 200, thereby improving surgical efficiency.
[0062] Unlike the embodiment described above where the separator 200 is detachably installed within the conduit 100, in order to reduce the difficulty of installing and disassembling the separator 200, such as... Figure 1 and Figure 5 As shown, in one embodiment, the medical wire guide 1000 further includes a wire splitter cap 400, which is detachably installed at an opening of the wire guide tube 100. A fixing groove 410 is provided on the inner wall of the wire splitter cap 400, and the separator 200 is detachably installed in the fixing groove 410.
[0063] In this application, by introducing a suture separator 400 and installing the separator 200 in the fixing groove 410 of the suture separator 400, this design significantly reduces the difficulty of installing and removing the separator 200. Surgeons can more easily insert or remove the separator 200 without complicated procedures or tools, thereby improving surgical efficiency. Surgeons can install or remove the separator 200 as needed to adjust the suture layout and tension, thus ensuring the smooth progress of the surgery.
[0064] In one embodiment, the branch cap 400 is snapped into connection with the conduit 100, such as... Figure 4 As shown, an L-shaped snap-fit groove 120 is provided on one end of the conduit 100; as Figure 5 As shown, the inner wall of the splitter cap 400 is provided with a snap-fit protrusion 420, which engages with the snap-fit groove 120 to snap the splitter cap 400 onto one end of the conduit 100. By rotating the splitter cap 400, the splitter cap 400 can be screwed onto or unscrewed from the conduit 100.
[0065] like Figure 3 As shown, in one embodiment, a gasket 130 is also provided between the wire separator 400 and the wire guide tube 100 to prevent contamination by bodily fluids, etc., and to absorb slight vibrations that may occur during the operation, providing a stable operating experience.
[0066] To ensure that the separator 200 remains parallel to the axis of the conduit 100 and the axis of the branch cap 400, thereby reducing obstruction during installation and removal of the separator 200, such as... Figure 1 and Figure 5 As shown, in one embodiment, the fixing groove 410 on the splitter cap 400 is arranged along the axial direction of the conduit 100, so that the separator 200 can be installed in the fixing groove 410 along the axial direction of the conduit 100.
[0067] In this application, the axial design of the fixing groove 410 allows the separator 200 to slide smoothly during installation and removal, reducing jamming caused by angular deviations or space limitations. This improves the smoothness and efficiency of surgical procedures.
[0068] like Figure 1 As shown, in one embodiment, the separator 200 includes baffles 210, the number of baffles 210 is at least two, the baffles 210 are interlocked with each other by a groove, and the baffles 210 are mounted on the fixing groove 410 of the splitter cap 400.
[0069] For example, in one embodiment, two separators 200 are provided, and the two separators 200 divide the cable passage into two cable sub-channels. In another embodiment, three separators 200 are provided, and the three separators 200 divide the cable passage into six cable sub-channels. Of course, in some other embodiments, other numbers of separators 200 may be provided, such as four, five, or six.
[0070] For example, such as Figure 3 As shown, the baffle 210 is provided with a slot, and the baffles 210 are connected to each other through the slot.
[0071] To further facilitate the installation or removal of the baffle 210 by doctors, such as Figure 1 and Figure 2 As shown, in one embodiment, a portion of the structure of the baffle 210 extends from the conduit 100 beyond the splitter cap 400.
[0072] Secondly, embodiments of this application also provide a surgical device, including a suture hook 2000 and a medical suture passer 1000 as described in any of the above embodiments.
[0073] like Figure 6 As shown, the hook 2000 includes a handle 2100 and a hook 2200 disposed at one end of the handle 2100.
[0074] For example, the hook 2200 is fixedly connected to the hand handle 2100.
[0075] For example, the hand handle 2100 includes a handle end and a rod end, with one end of the rod end fixedly connected to the handle end. A hook 2200 is fixedly provided on the other end of the rod end, and the hook 2200 is used to hook the sewing thread.
[0076] For example, the maximum outer diameter of the arc-shaped structure of the rod end and the hook 2200 is less than or equal to the inner diameter of the wire passage, that is, the rod end and the hook 2200 can freely pass through the wire passage.
[0077] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0078] 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.
