Description

Technical Field

[0001] This invention relates to the field of orthopedic screw removal technology, and in particular to a multifunctional orthopedic screw removal instrument. Background Technology

[0002] In orthopedic clinical treatment, steel nails are often implanted to fix the bone after fracture surgery. After the patient's bone has recovered to the expected clinical standard, the steel nails need to be removed with the help of special instruments. In the prior art, such as the orthopedic nail removal device disclosed in Chinese invention patent with publication number CN222357634U, although the steel nail can be automatically removed, reducing the burden of manual operation to a certain extent, this device does not fully consider the diversity of steel nail implantation positions and the differences in nail insertion orientation in clinical practice. Due to the diversity of steel nail insertion positions and orientations, when the steel nail is facing downwards or located in a position where the base is difficult to fix, the device cannot adjust the nail removal direction, resulting in poor adaptability and difficulty in meeting the nail removal needs of complex clinical scenarios. Summary of the Invention

[0003] In order to overcome the shortcomings of existing orthopedic nail removal devices, which can automatically remove steel nails but do not take into account the diversity of the position and orientation of the steel pins, resulting in poor adaptability, this invention provides a multifunctional orthopedic nail removal instrument.

[0004] A multifunctional orthopedic screw removal instrument includes a rod body, an electric push rod, a clamp, an electric telescopic rod, and a barrier component. An electric push rod is installed on the right side of the rod body. A clamp is slidably connected inside the rod body, and the push rod of the electric push rod is fixedly connected to the clamp, allowing the clamp to move left and right. Multiple electric telescopic rods are installed on the left side of the outer side of the rod body, extending to conform to the skin of human tissue. A barrier component for preventing contamination is installed on the clamp.

[0005] Furthermore, it also includes a grip and a controller; the grip is installed in the middle of the stick, and the grip has a built-in battery assembly and circuit assembly; the controller is installed on the right side of the stick.

[0006] Furthermore, the telescopic pole of the electric telescopic pole is detachably connected to an anti-slip sleeve.

[0007] Furthermore, a pressure sensor is installed in the anti-slip sleeve.

[0008] Furthermore, a wiping sleeve is fitted onto the telescopic rod of the electric telescopic pole, and the wiping sleeve is fixed by an insert block, which is located on the left side of the fixing part of the electric telescopic pole.

[0009] Furthermore, the barrier assembly includes a barrier ring, a telescopic post, a protective sleeve, an elastic membrane, and a rubber ring; the insertion part of the barrier ring is inserted into the annular insertion hole of the clamp; a rubber ring is provided in the annular groove on the left side of the barrier ring; a protective sleeve is connected to the inner side of the barrier ring through the telescopic post, and the protective sleeve is fitted onto the clamping part; an elastic membrane is provided between the barrier ring and the protective sleeve, and the elastic membrane blocks dirt from entering.

[0010] Furthermore, the elastic membrane adapts to deformation when clamped by the clamping part.

[0011] Furthermore, the wiping sleeve is fixed with inserts, and the fixed part of the electric telescopic rod has two insertion holes for inserting the inserts.

[0012] Furthermore, after the plug is inserted into the annular socket, it forms an annular slot for inserting the insert piece.

[0013] Furthermore, the insertion resistance between the plug and the annular socket is greater than the sliding resistance between the rubber ring and the inner wall of the rod. Beneficial effects

[0014] This invention effectively solves the problem of poor adaptability in existing orthopedic nail removal devices. Doctors can adjust the orientation of the rods to accommodate the different nail insertion positions and orientations in various parts of the body. After the nail is fixed by the clamping part of the clamp, an electric push rod drives the clamp to move, achieving automated nail removal. This saves time and effort and meets the needs of diverse nail removal scenarios. To improve nail removal stability, after the clamping part is fixed to the nail, multiple electric telescopic rods can drive anti-slip sleeves to adaptively resist the surrounding tissue. When the pressure sensor in the anti-slip sleeve detects a threshold value, the telescopic rod stops extending, significantly reducing the accuracy requirements for the doctor's handheld instruments. Simultaneously, for blood, fragmented tissue, and other contaminants generated during nail removal, a wiping sleeve on the left side of the electric telescopic rod's fixing part can promptly clean the surface of the telescopic rod. The detachable design of the anti-slip sleeve and wiping sleeve facilitates subsequent disinfection. The barrier component forms a barrier surface through a barrier ring, protective sleeve, elastic membrane, and rubber ring, preventing contaminants from contacting the clamp fixing part. When the clamp moves to the left, the rubber ring can also scrape away contaminants from the inner wall of the rod. In addition, when disassembling the barrier component, it can be separated from the clamp by engaging the insert with the ring slot. During installation, the clamp can be automatically pressed against the barrier ring by moving the clamp to the left, overcoming the problem of laborious and ineffective manual operation, and taking into account both nail removal efficiency and ease of cleaning.

Detailed Implementation

[0017] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way. Example

[0018] A multifunctional orthopedic screw removal instrument, such as Figures 1-9 As shown, it includes a rod body 1, an electric push rod 2, a clamp 3, an electric telescopic rod 4, and a barrier component 5; the electric push rod 2 is installed on the right side of the rod body 1, and the telescopic part of the electric push rod 2 is located inside the rod body 1; the clamp 3 is slidably connected inside the rod body 1, and the clamp 3 clamps and fixes the steel nails; the push rod of the electric push rod 2 is fixedly connected to the clamp 3, and the clamp 3 is moved left and right by the electric push rod 2; multiple electric telescopic rods 4 are installed on the left side of the outer side of the rod body 1, and the telescopic parts of the electric telescopic rods 4 extend to fit against human tissue and skin; the barrier component 5 for blocking dirt is installed on the clamp 3.

[0019] It also includes a grip part 6 and a controller 7; the grip part 6 is installed in the middle of the rod body 1, and the grip part 6 has a built-in battery assembly and circuit assembly; the controller 7 is installed on the right side of the rod body 1, and the doctor controls the operation of the invention through the button on the controller 7.

[0020] An anti-slip sleeve 4a is detachably connected to the telescopic rod of the electric telescopic rod 4.

[0021] The anti-slip sleeve 4a is equipped with a pressure sensor, which detects the magnitude of the force applied when the anti-slip sleeve 4a comes into contact with human tissue.

[0022] A wiping sleeve 4b is fitted onto the telescopic rod of the electric telescopic rod 4. The wiping sleeve 4b is fixed by a plug 4c and is fixed on the left side of the fixing part of the electric telescopic rod 4.

[0023] The barrier assembly 5 includes a barrier ring 51, a telescopic post 52, a protective sleeve 53, an elastic membrane 54, and a rubber ring 55. The insertion part 51a of the barrier ring 51 is inserted into the annular insertion hole 3b of the clamp 3. A rubber ring 55 is provided in the annular groove 51b on the left side of the barrier ring 51, which forms a seal with the inner wall of the rod body 1 to block dirt. The protective sleeve 53 is connected to the inner side of the barrier ring 51 through the telescopic post 52, and the protective sleeve 53 is fitted on the clamping part 3a. An elastic membrane 54 is provided between the barrier ring 51 and the protective sleeve 53 to block dirt from entering.

[0024] The elastic membrane 54 adapts to deformation when clamped by the clamping part 3a.

[0025] The wiping sleeve 4b is fixedly connected to the insert 4d, and the fixed part of the electric telescopic rod 4 has two insertion holes for the insert block 4c to be inserted.

[0026] After the plug part 51a is inserted into the annular socket 3b, it forms an annular slot 10 for inserting the insert piece 4d.

[0027] The insertion resistance between the insertion part 51a and the annular insertion hole 3b is greater than the sliding resistance between the rubber ring 55 and the inner wall of the rod 1.

[0028] While existing orthopedic screw removal devices can automatically remove screws, they do not consider the diverse positions and orientations of the screws, resulting in poor adaptability. To address this, this invention is proposed. In operation, the surgeon holds the gripping part 6 with one hand and the right side of the rod 1 with the other, with the thumb able to operate the controller 7 to control the operation of each component. Once the screw to be removed is identified, the orientation of the rod 1 is adjusted to match the orientation of the screw, and then the clamping part 3a of the clamping device 3 is controlled to clamp and fix the screw. Figure 2As shown, the push rod of the electric push rod 2 is then moved to the right, and the push rod drives the clamp 3 and the steel nail held by the clamping part 3a to move to the right, thereby pulling the steel nail out of the human tissue in the direction of the steel nail. This achieves automatic removal of the steel nail and can adapt to multiple steel nail insertion positions and directions in the human body. It is highly adaptable and saves time and effort. Furthermore, to improve the stability during nail removal and reduce the accuracy requirements for doctors holding the present invention, after the nail is clamped and fixed in the clamping part 3a, the telescopic rods of multiple electric telescopic rods 4 are extended to push the anti-slip sleeve 4a against the human tissue around the nail. When the pressure sensor value in the anti-slip sleeve 4a reaches the threshold, the telescopic rods of the electric telescopic rods 4 stop extending. This allows multiple electric telescopic rods 4 to drive the anti-slip sleeve 4a to adaptively contact the human tissue and conform to the skin, thus adding an additional point of force and adapting the point of force to the human tissue. This makes it easier and more accurate for doctors to maintain the orientation of the rod 1, thereby improving the stability during nail removal. Furthermore, when the steel nail is pulled out, contaminants such as blood, medicine, and fragmented human tissue may adhere to the invention. To address this, a wiping sleeve 4b is fixed to the left side of the fixing part of the electric telescopic rod 4 using a plug 4c. This wiping sleeve 4b slides relative to the telescopic rod of the electric telescopic rod 4. The wiping sleeve 4b is used to wipe away the contaminants adhering to the telescopic rod in a timely manner. At the same time, the anti-slip sleeve 4a is detachably connected to the telescopic rod, so the anti-slip sleeve 4a and the wiping sleeve 4b can be removed periodically for disinfection and cleaning. Meanwhile, a barrier component 5 is set up, and the barrier ring 51 is inserted into the annular insertion hole 3b so that the barrier ring 51 moves with the clamp 3. The protective sleeve 53, elastic membrane 54 and rubber ring 55 form a barrier surface, which can prevent dirt from moving to the fixed part of the clamp 3, thereby blocking the dirt on the left side of the barrier surface. When the clamp 3 moves to the left and drives the rubber ring 55 to move to the left, the dirt adhering to the inner wall of the rod 1 can be scraped to the left for subsequent cleaning. Furthermore, when it is necessary to clean the barrier component 5, such as... Figure 1 As shown, the controllable electric push rod 2 pushes the clamp 3 to the left, exposing the barrier component 5 on the left side of the rod body 1. At this time, the doctor can directly clean and disinfect the barrier component 5. Of course, when it is necessary to disassemble the barrier component 5 for further cleaning or replacement, such as... Figure 5 , Figure 6As shown, first pull out the insert 4c, then rotate the wiping sleeve 4b to insert the insert 4d into the annular slot 10. Then, fix the wiping sleeve 4b again with the insert 4c. After that, control the electric push rod 2 to move the clamp 3 to the right. At this time, because the insert 4d is inserted into the annular slot 10 and abuts against the right side of the barrier ring 51, the barrier component 5 cannot move to the right with the clamp 3, thus separating the barrier component 5 from the clamp 3. In this way, the doctor does not need to work hard to remove the barrier component 5. After the barrier component 5 is separated, the doctor can further clean or change the care.

[0029] It should be noted that when the clamping part 3a of the clamping device 3 clamps, the protective sleeve 53 will move accordingly. At this time, the telescopic column 52 will adapt to the extension and retraction. Meanwhile, when the blocking component 5 is reinstalled in the clamping device 3, the clamping device 3 is first pushed to the left, and the blocking ring 51 is inserted into the annular socket 3b (at this time, the doctor inserts it, and there is no need to force it to be fully inserted). The clamping device 3 is moved to the right so that the left side of the blocking ring 51 is flush with the left side of the rod 1, so that the insert 4d can be placed against the left side of the blocking ring 51. Then, the clamping device 3 is controlled to move to the left to fully squeeze the blocking ring 51 into the annular socket 3b, thereby realizing the automatic clamping of the clamping device 3 and the blocking component 5, overcoming the problem that manual operation is laborious and ineffective.

[0030] As can be seen from the above, the present invention effectively solves the problem of poor adaptability of existing orthopedic nail removal devices. Doctors can adjust the orientation of the rod 1 to adapt to the nail insertion position and orientation in different parts of the human body. After the nail is fixed by the clamping part 3a of the clamp 3, the electric push rod 2 drives the clamp 3 to move to achieve automated nail removal, saving time and effort and meeting the needs of various nail removal scenarios. To improve the stability of nail removal, after the clamping part 3a fixes the nail, multiple electric telescopic rods 4 can drive the anti-slip sleeve 4a to adaptively resist the human tissue around the nail. When the pressure sensor in the anti-slip sleeve 4a detects a value that reaches a threshold, the telescopic rod stops extending, thus greatly reducing the accuracy requirements for doctors to hold the instruments. Meanwhile, for blood, fragmented human tissue, and other contaminants generated during nail removal, the wiping sleeve 4b on the left side of the fixed part of the electric telescopic rod 4 can promptly clean the surface of the telescopic rod. The detachable design of the anti-slip sleeve 4a and the wiping sleeve 4b facilitates subsequent disinfection. The barrier component 5 forms a barrier surface through the barrier ring 51, protective sleeve 53, elastic membrane 54, and rubber ring 55, which not only prevents contaminants from contacting the fixed part of the clamp 3, but also allows the rubber ring 55 to scrape away contaminants from the inner wall of the rod body 1 when the clamp 3 moves to the left. In addition, when disassembling the barrier component 5, it can be separated from the clamp 3 by the engagement of the insert 4d with the annular slot 10. During installation, the leftward movement of the clamp 3 can automatically press the barrier ring 51, overcoming the problems of laborious and ineffective manual operation, and balancing nail removal efficiency and cleaning convenience.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
