Description

Technical Field

[0001] This utility model relates to the field of medical surgical technology, and in particular to a disposable pelvic and acetabular surgical auxiliary muscle protection sleeve. Background Technology

[0002] In the medical field, pelvic and acetabular surgery is a crucial method for treating serious conditions such as fractures and deformities of the pelvic and acetabular region. However, the complex anatomy of this area, with its dense network of nerves and blood vessels and abundant, interwoven muscle tissue, makes the surgical procedure extremely challenging. It requires not only precise treatment of the affected area but also meticulous care to protect surrounding tissues and organs to minimize surgical risks and postoperative complications. Against this backdrop, the development of disposable pelvic and acetabular surgical aids with muscle protection sleeves has become an important area of ​​research in the medical field, holding significant importance for improving surgical outcomes and patient recovery.

[0003] In the past, pelvic and acetabular surgeries typically involved surgeons using conventional scalpels to incise the skin and tissue, and employing ordinary retractors to expose the surgical field. When fixing the bone, Kirschner wires were generally used directly, relying on the surgeon's experience and feel to insert them into the appropriate positions to achieve reduction and fixation of the fracture site. While these traditional methods could accomplish the surgery to a certain extent, their drawbacks have gradually become apparent with advancements in medicine and patients' increasing demands for treatment outcomes.

[0004] Currently, there is a problem with inadequate muscle protection during Kirschner wire fixation in pelvic and acetabular surgeries. During surgery, the high-speed drill moves the Kirschner wires, and due to the lack of effective protective measures, muscles near the incision are easily caught in the wires. This not only increases intraoperative bleeding, affects the surgeon's field of vision, and prolongs the operation time, but also causes serious muscle damage. Damaged muscles cannot function properly, leading to postoperative pain, muscle weakness, and other symptoms, severely hindering postoperative recovery and reducing the patient's quality of life. Therefore, a disposable pelvic and acetabular surgical auxiliary muscle protection cannula is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a disposable pelvic and acetabular surgical auxiliary muscle protection sleeve, which aims to improve the problem that the rotation of Kirschner wires during installation can cause muscle strain to patients.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A disposable pelvic and acetabular surgical auxiliary muscle protection sleeve includes a main tube, which is the entire device and provides support for the whole device; a handle, which is located on the outer wall of the main tube for moving the main tube; and a connecting component, which is located on the outer wall of the handle for connecting the main tube and the handle.

[0032] 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.

[0033] Reference Figure 1 - Figure 5This utility model provides an embodiment of a disposable pelvic and acetabular surgical auxiliary muscle protection sleeve, comprising a main tube 1, which is the entire device and provides support. It is made of medical-grade stainless steel, a material known for its high strength, light weight, and excellent biocompatibility, providing stable support and withstanding various external forces during surgery to ensure instrument stability. A handle 2 is located on the outer wall of the main tube 1 for moving it. The handle 2 is ergonomically designed with a curved shape and is made of soft, non-slip medical-grade silicone, providing a comfortable grip and preventing hand slippage during surgery. The surgeon can use it to move the main tube 1 flexibly and precisely adjust its position. A connecting component is located on the outer wall of the handle 2 to connect the main tube 1 to the handle 2. The main tube 1 contains an inner tube 9 made of medical-grade polyethylene, a smooth material with a low coefficient of friction, allowing Kirschner wires to pass through smoothly. A groove 3 is provided inside the handle 2 to further enhance grip stability, allowing the surgeon's fingers to be inserted for more precise operation. The main tube has a diameter of 5mm, and the inner tube has a diameter of 3mm.

[0034] Specifically, in pelvic and acetabular surgery, the placement of Kirschner wires is a crucial step. At this time, medical staff use handle 2 to precisely move the main tube 1. Notably, handle 2 is designed with a unique upward curve and features carefully crafted grooves 3 on its surface. This design greatly conforms to ergonomic principles, providing doctors with a more stable and comfortable grip. The main tube 1 is 12cm long, while the Kirschner wire is 25cm long and needs to be clamped inside the battery drill. The outer diameter of the main tube 1 is 5mm, and the inner diameter of the inner tube 9 is 3mm, allowing Kirschner wires up to 2.5mm to pass through smoothly. When using a high-speed drill for Kirschner wire fixation, the main tube 1 effectively isolates the Kirschner wire from surrounding muscles, protecting the muscles while facilitating accurate fixation.

[0035] Reference Figure 3 - Figure 5 The connecting component includes a connecting ring 4, which is made of high-strength medical-grade engineering plastic. This material not only has good mechanical strength and can withstand various external forces generated during surgical operations, but also has excellent chemical stability and will not cause adverse reactions with human tissue. The outer wall of the connecting ring 4 is fixedly connected to the outer wall of the handle 2. A moving groove 6 is opened inside the connecting ring 4. A pull block 5 is slidably connected inside the connecting ring 4. The design of the pull block 5 fully considers the convenience and comfort of the doctor's operation. Its surface is specially frosted to increase friction and make it easy for the doctor to pull with his fingers. A locking post 10 is fixedly connected to one end of the pull block 5. The outer wall of the locking post 10 is slidably connected to the inside of the main tube 1. A limiting ring 8 is fixedly connected to the outer wall of the locking post 10. The outer wall of the limiting ring 8 is slidably connected to the inside of the moving groove 6. A spring 7 is sleeved on the outer wall of the locking post 10. One end of the spring 7 is fixedly connected to the inner wall of the connecting ring 4, and the other end of the spring 7 is fixedly connected to the inner wall of the limiting ring 8.

[0036] Specifically, before performing pelvic and acetabular surgery, the surgeon needs to carefully select a suitable surgical aid based on the specific surgical situation. Once the device is selected, installation preparations begin. First, the surgeon pulls block 5, which causes the limiting ring 8 to slide smoothly within the moving groove 6, while simultaneously compressing the spring 7. Under this series of actions, the locking post 10 moves inward, providing sufficient width for inserting the main tube 1. After the main tube 1 is in place, block 5 is released. The spring 7 then springs back, causing the locking post 10 to quickly return to its original position, precisely locking into the main tube 1 and firmly securing it. This ensures the entire device remains stable during the surgery, providing reliable support for subsequent surgical procedures.

[0037] Working principle: When placing Kirschner wires, the handle 2 moves the main tube 1. The handle 2 has an upward arc and the groove 3 on the surface of the handle 2 can be used to better grip it. At the same time, the main tube 1 is 12cm long and the Kirschner wire is 25cm long. It needs to be clamped in the battery drill. The outer diameter is 5mm and the inner tube 9 is 3mm, which can just pass through Kirschner wires up to 2.5mm in diameter. This can protect the muscles during drilling while facilitating the fixation of the Kirschner wire.

[0038] In addition, before the operation, a suitable device can be selected according to the surgical situation. Then pull the pull block 5, which will cause the limiting ring 8 to slide inside the moving groove 6 and compress the spring 7, so that the locking post 10 moves inward to leave the width for the main tube 1 to be inserted. Then release the pull block 5, which will cause the locking post 10 to return to its original position and be inserted into the main tube 1 to fix it and keep the device stable.

[0039] 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.
