Description

Technical Field

[0001] This utility model relates to the field of intramedullary nail protective sleeve technology, and in particular to intramedullary nail and robotic opening protective sleeve. Background Technology

[0002] An intramedullary nail protector sleeve is a medical device used in fracture treatment, particularly when intramedullary nailing is employed. Intramedullary fixation is a common fracture treatment method that involves inserting a long nail (intramedullary nail) into the fractured long bone shaft to help stabilize the fracture site and promote bone healing.

[0003] The current protective sleeve has a flat bottom, which makes it easy to shift when tapping. If it shifts and then recalibrates, the tapping position will change, causing multi-point damage to the patient's bones. It is also easy to slip during tapping, which can not only cause contusions to the patient's bones but also injure medical staff.

[0004] Based on this, those skilled in the art have proposed a conveniently positioned intramedullary nail and a robotic opening protective sleeve. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide an intramedullary nail and a protective sleeve for robotic opening.

[0006] The technical solution of this utility model is as follows: an intramedullary nail and a robotic opening protective sleeve, including a picking end, both ends of which are set at inclined striking ends, two sleeves are symmetrically fixedly connected below the striking ends, a limiting end is fixedly connected to the bottom of each sleeve, a through hole is opened inside each sleeve, the two ends of the through hole respectively penetrate the limiting end and the striking end, a fixing tooth is equidistantly opened at the bottom of the limiting end, and pin holes are equidistantly opened on the outside of the sleeve and outside the through hole, one end of the pin hole penetrates the limiting end and the other end extends to the outside of the sleeve.

[0007] Using the above-mentioned technical means, the sleeve is placed at the target position, and then the fixing teeth at the bottom of the sleeve will penetrate into the bone at the target position by tapping the striking end. Then, Kirschner wires are inserted into the pin hole to further fix the sleeve. Finally, an internal fixation device is inserted into the through hole, thus completing the overall operation steps.

[0008] In a preferred embodiment, both sides of the picking end are provided with curved structures to facilitate picking.

[0009] By using the above-mentioned technical means, when the picking end slides, the curved structure can increase the friction between the user and the picking end, which can effectively prevent the hand from slipping out.

[0010] In a preferred embodiment, the angle between the sleeve and the corresponding striking end is set to 90 degrees.

[0011] By using the above-mentioned technical means, setting the angle to ninety degrees can make the direction of force application on the sleeve perpendicular, thereby better transmitting force.

[0012] In a preferred embodiment, both the picking end and the striking end have rounded chamfers at their edges.

[0013] The purpose of using the above-mentioned technical means is to protect the user's palm when the picking end moves quickly during a tap.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention involves striking the striking end, causing the fixing teeth at the bottom of the sleeve to penetrate the bone at the target location. Then, a Kirschner wire is inserted into the needle hole to further fix the sleeve. Subsequently, an internal fixation device is inserted into the through hole. Compared with traditional devices, this device inserts the fixing teeth into the bone structure when striking, thus preventing slippage between the sleeve and the bone structure and avoiding additional trauma to the patient due to slippage.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example like Figures 1-4As shown, this utility model provides an intramedullary nail and a robotic opening protective sleeve: including a picking end 1, both sides of the picking end 1 are provided with curved structures for easy picking. The user holds the outside of the curved structure. When the picking end 1 slides, the curved structure can increase the friction between the user and the picking end 1, which can effectively prevent the hand from slipping. Both ends of the picking end are set at the inclined striking end, and the striking end and the picking end are set at an acute angle. This way, the user can maintain an appropriate distance from the striking end when picking it up, so as to prevent the user from being hit and injured. Two sleeves are symmetrically fixedly connected below the striking end. The angle between the sleeve and the corresponding striking end is set to 90 degrees. Setting it to 90 degrees makes the force applied by the sleeve perpendicular, thus better transmitting the force. The bottom of the sleeve is fixedly connected to a limiting end. The bottom of the limiting end is provided with fixing teeth at equal intervals. The fixing teeth directly contact the patient's bone structure. By tapping the tapping end, the fixing teeth are inserted into the bone structure. This can prevent the sleeve from slipping between the sleeve and the bone structure and avoid additional trauma to the patient due to slipping. The sleeve has through holes inside, with the limiting end and the striking end passing through the two ends of the through holes respectively. The through holes are used to install internal fixing devices. The sleeve has pin holes at equal intervals on the outside of the through hole. One end of the pin hole passes through the limiting end and the other end extends to the outside of the sleeve. The pin holes are used to insert Kirschner wires for further fixation. Both the picking end and the striking end have rounded chamfers at their edges. The purpose of the rounded corners is to protect the user's palm when the picking end moves quickly during striking. Working principle: In actual use, the staff takes the device and places the sleeve 3 at the target position. Then, by tapping the striking end 2, the fixing teeth 6 at the bottom of the sleeve 3 will penetrate the bone at the target position. Then, the Kirschner wire is inserted into the needle hole 7 to further fix the sleeve 3. Then, the internal fixation device is inserted into the through hole 4, thus completing the overall operation steps.

[0019] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
