Abstract
Description
Technical Field
[0001] The present application relates to orthopedic instruments, and in particular to a nail removal forceps for removing memory alloy suture nails. Background Art
[0002] Memory alloy saddle nails are mainly used for trauma and fusion of irregular bones in hand and foot surgery, fixation of small bone fragments near joints, corrective surgery for hallux valgus, fixation of cruciate ligaments, internal fixation of sternal rib fractures, internal fixation of frontal fractures, and use with internal fixation plates on weight-bearing bones of the limbs, which can effectively reduce the chance of bone nonunion.
[0003] Fractures can cause disability, limit patients' activities, make them unable to take care of themselves, increase the incidence of lung infections and bedsores, and thus lead to an increase in the patient's mortality rate.
[0004] With the progress of society, the rapid development of industry and transportation, the incidence of fractures has also greatly increased. For trauma internal fixation surgery, locking plates and intramedullary nails are the preferred implants for treating fractures.
[0005] However, for some types of fractures, a single steel plate or intramedullary nail cannot effectively achieve a strong internal fixation effect, especially for some small fracture fragments, which cannot achieve effective and continuous pressure.
[0006] Bone nonunion is a common case in orthopedics. The lack of axial pressure leads to the appearance of bone gaps, resulting in bone nonunion. The axial continuous pressure of the saddle nail can just make up for it, and cooperate with the internal fixation plate to achieve a perfect fixation effect, thereby reducing the incidence of bone nonunion.
[0007] However, the staples need to be removed later, and it is difficult to remove them without good tools. Utility Model Content
[0008] The utility model aims to provide a nail removal forceps for taking out memory alloy saddle staples, which facilitates the taking out of memory alloy saddle staples.
[0009] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.
[0010] The embodiment of the present application discloses a nail removal pliers for removing memory alloy staples, comprising a first pliers body and a second pliers body hingedly connected by a pin, the first pliers body comprising a first pliers head and a first pliers handle, the second pliers body comprising a second pliers head and a second pliers handle, the first pliers head forming a flat hook body, the second pliers head forming a pointed hook body that fits and clamps the two side surfaces of the flat hook body, a cavity is formed between the two pointed hook bodies, and a support surface is formed on the side of the cavity away from the flat hook body.
[0011] Preferably, in the above-mentioned nail removal forceps for removing memory alloy staples, a clamping space is formed between the first clamp head and the second clamp head.
[0012] Preferably, in the above-mentioned nail removal forceps for removing the memory alloy staples, the inner diameter of the memory alloy staples is slightly larger than the outer diameter of the second forceps head.
[0013] Preferably, in the above-mentioned nail removal forceps for removing memory alloy staples, a spring sheet is provided between the first clamp handle and the second clamp handle.
[0014] Preferably, in the above-mentioned nail removal forceps for removing the memory alloy staples, barbs are formed on the memory alloy staples.

[0019] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Combination Figure 1-2The present invention shows a nail removal forceps 100 for removing memory alloy saddle stitch nails, comprising a first clamp body 102 and a second clamp body 103 hinged by a pin 101, the first clamp body 102 comprising a first clamp head 104 and a first clamp handle 105, the second clamp body 103 comprising a second clamp head 106 and a second clamp handle 107, the first clamp head 104 forming a flat hook body 108, the second clamp head 106 forming a sharp hook body 109 for clamping the two sides of the flat hook body 108, a cavity 110 formed between the two sharp hook bodies 109, and a support surface 111 formed on the side of the cavity 110 away from the flat hook body 108. A clamping space 112 is formed between the first clamp head 104 and the second clamp head 106. The inner diameter of the memory alloy saddle stitch nail 200 is slightly larger than the outer diameter of the second clamp head 106. A spring sheet 113 is arranged between the first clamp handle 105 and the second clamp handle 107. A barb 201 is formed on the memory alloy staple 200 .
[0021] In this embodiment, the removal of the memory alloy saddle staple is facilitated.
[0022] The difficulty in removing memory alloy staples is:
[0023] 1. The memory alloy suture nail implant is relatively small in size and is not easy to perform micro-operation directly;
[0024] 2. When the memory alloy suture nail implant is removed, irregular callus will be distributed around the fracture line, making it difficult to operate;
[0025] 3. Memory alloy suture nail implants are prone to secondary fractures when removed due to continuous circumferential pressure;
[0026] The specific removal method is as follows:
[0027] 1. Cut the skin to expose the site where the staples are implanted;
[0028] 2. Inject 0℃-5℃ sterile ice saline into the staples through a syringe to soften the material;
[0029] 3. Use the tip of the nail removal pliers to penetrate under the arch of the crossbeam of the saddle nail and gently pull it out;
[0030] 4. After removal, suture the wound.
[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0032] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
