Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a wrist bone removal auxiliary tool. Background Art

[0002] Wrist removal surgery is a complex and technically demanding procedure that is often used to treat serious injuries or diseases of the wrist joint, such as nonunion of wrist fractures or malignant tumors. The purpose of this type of surgery is to remove one or more wrist bones to relieve pain and improve joint function. Wrist removal aids are tools designed specifically for this type of surgery to help doctors perform surgical steps more accurately and safely. However, although these tools have greatly improved the efficiency and safety of surgery, they still have some problems and limitations.

[0003] First, existing wrist bone removal tools often lack flexibility and adjustability. During surgery, doctors may need to adjust the use of tools according to the patient's specific situation and the specific structure of the wrist joint. However, most tools currently on the market are fixed in design and cannot be adjusted according to the specific needs of the surgery, which limits the doctor's flexibility and may lead to longer surgery time and increased risks for patients.

[0004] Secondly, even if some tools can be adjusted, they may have stability issues after adjustment, such as shaking, which not only affects the accuracy of the operation, but also increases the risk of accidentally damaging the patient's tissue during the operation. When performing wrist bone removal surgery, extremely high precision and stability are required because the wrist joint is composed of multiple small bones and complex structures. Any slight error may lead to serious consequences, such as dysfunction or long-term pain.

[0005] In addition, traditional wrist bone removal surgery often requires a larger incision, which naturally brings higher trauma and longer recovery time. Patients may experience more pain after surgery and have a higher risk of infection. At the same time, larger incisions may also lead to unsightly scars.

[0006] Therefore, it is necessary to develop a new generation of wrist bone removal auxiliary tools, which should not only provide better adjustability and stability to meet the needs of different surgical situations, but also be designed to be more humane and reduce trauma to patients.

[0007] Currently, no effective solution has been proposed for the above technical problems. Utility Model Content
