Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tendon remover capable of local anesthesia. Background Art

[0002] In patients with clinical orthopedic sports injuries or violent trauma from car accidents, violence causes the knee joint to twist, generating huge shear and tensile forces, resulting in single or multiple ligament ruptures in the knee joint; in terms of the Achilles tendon, direct or indirect violence can cause Achilles tendon rupture. If the complete rupture is not healed in time, contracture will occur at both ends of the rupture; in developmental diseases, such as patellofemoral arthritis or patellofemoral ligament injury caused by trauma. All of the above diseases require autologous or allogeneic tendon transplantation for surgical reconstruction of the continuity of ligaments or tendons. Allogeneic tendon transplantation usually results in rejection, so autologous tendon is usually considered first to reconstruct ligaments. The first step of the operation is to use a tendon retriever to remove the gracilis, semitendinosus or plantaris muscle for tendon reconstruction. After the tendon is removed, anesthesia is usually required at the location where anesthesia is required in the human body to reduce the patient's pain and discomfort. Since the anesthesia location is located in the body, it is necessary to use other openings on the human body for anesthesia. Due to the distance difference, not only does it need to increase the length of the anesthesia tool, but the anesthesia location is also difficult to control. Therefore, it is necessary to inject more anesthetic solution to achieve the anesthesia effect. After anesthesia is completed, the tendon retriever needs to be pulled out to continue other operations. Since the existing tendon retriever can only complete the tendon removal function, when the tendon retriever is pulled out, the tendon will be separated from the tendon retriever. When the tendon needs to be removed a second time, it is necessary to find the location of the tendon to be removed, which causes certain difficulties to the operation and reduces the efficiency of the operation. Summary of the invention

[0003] In view of this, the present invention provides a tendon remover capable of local anesthesia to solve the above technical problems.

[0032] like Figure 2 and Figure 3As shown, the inner end of the outer tube body 1 has a U-shaped notch 12 radially penetrating the outer tube body 1, and the U-shaped notch 12 is connected to the hollow channel 11; the tendon removal rod body 2 includes a handle section 25, a straight rod section 21 and a tendon removal head 22 connected in sequence, and the tendon removal head 22 includes a connecting rod 221 and a pull rod 222 connected together in sequence, and the connecting rod 221 is connected to the straight rod section 21, and the outer diameter of the pull rod 222 is larger than the outer diameter of the connecting rod 221, wherein the pull rod 222 is An arc-shaped concave surface 224 is provided on the outer surface of the rod 222, and one end of the arc-shaped concave surface 224 extends to the end surface of the pull rod 222 close to the connecting rod 221.

[0037] like Figure 6As shown, the limiting mechanism 4 includes a fixed clamping plate assembly 41 and a floating clamping plate assembly 42 which are relatively arranged. The fixed clamping plate assembly 41 has a T-shaped strip 411 which is tightly matched with the corresponding T-shaped groove 15 located on the inner wall of the positioning wire perforation 14 and a fixed arc plate 412 which is fixedly connected to the T-shaped strip 411.

[0038] The floating clamping plate assembly 42 also includes a plurality of floating blocks 421, wherein the T-shaped block 4211 of the floating block 421 is slidably matched with the corresponding T-shaped slot 15 located on the inner wall of the positioning wire through hole 14, and two adjacent floating blocks 421 are tightly fitted to prevent the floating block 421 from deflecting, and a first elastic member 422 fixedly arranged on the back of the T-shaped block 4211 is pressed against the bottom surface of the T-shaped slot 15, and the floating arc plate 4213 is fixedly connected to the web of the corresponding T-shaped block 4211, and the wedge surface 4212 located at the top or bottom of the web is in contact with the corresponding adjacent T-shaped block 4211. The wedge surface 4212 is in contact and connection with the T-slot 15, and the wedge surface 4212 of the driving pressure block 423 which is slidably matched with the outer end of the positioning wire through-hole 14 is in contact and connection with the corresponding wedge surface 4212 on the T-block 4211 located at the top. Pressing the driving pressure block 423 causes all the floating blocks 421 to be in a retracted state. The above structure enhances the rigidity of the floating blocks 421. When the driving pressure block 423 is pressed, all the floating blocks 421 can be synchronously retracted and moved. When the floating blocks 421 are released, the first elastic member 422 pushes the corresponding floating blocks 421 to extend outward for clamping, so that the clamping force is stable.

[0039] A second elastic member 427 is provided on the bottom surface of the driving pressure block 423, and the second elastic member 427 is pressed against the top surface of the T-shaped block 4211 at the top, and the second elastic member 427 is located in the T-shaped groove 15. The setting of the second elastic member 427 avoids the defect of unstable clamping force adjustment caused by the jumping of the floating block 421.

[0040] Preferably, the first elastic member 422 includes an L-plate 4221 fixedly connected to the corresponding T-shaped block 4211 and a straight plate 4223 affixed to the bottom of the T-shaped slot 15 , and the L-plate 4221 is fixedly connected to the straight plate 4223 via a first V-shaped plate 4222 .

A sliding rod 425 is provided in the central channel of the adjusting screw rod 424, and a return spring 426 sleeved on the sliding rod 425 is pressed between the upper end plate of the sliding rod 425 and the adjusting screw rod 424. When the sliding rod 425 is reset, the bottom surface of the lower end plate of the sliding rod 425 is flush with the end surface of the adjusting screw rod 424. When it is necessary to keep the elastic clamping port open, the adjusting screw rod 424 is rotated to adjust the driving pressure block 423. The dynamic pressure block 423 is pressed, and the size of the clamping force can also be controlled by adjusting the adjusting screw rod 424. When inching clamping is required, it can be achieved by manually pressing the sliding rod 425. The structure is simple and easy to operate. When the tendon remover needs to be pulled out, adjust to the appropriate clamping force to ensure that the positioning member 3 slides along the elastic clamping mouth and does not separate from the limiting mechanism 4. When the tendon remover needs to be used for the second time, the tendon remover is put on along the positioning member 3 so that the end of the positioning member 3 is fixed at the lowest end of the limiting mechanism 4, and then the positioning member 3 is fixed by the combination of the retractor and the umbrella hook. The elastic clamping mouth is opened, and the tendon remover is quickly positioned at the corresponding tendon removal position using the guidance of the positioning member 3, and then placed for use.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
