Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to an electric scalp hemostatic gun. Background Art

[0002] In brain surgery, craniotomy is a relatively common treatment method. Craniotomy, also known as craniotomy, is a type of cranial surgery, which refers to opening the patient's skull through mechanical equipment to perform some unconventional treatments. The scalp needs to be incised before opening the skull. When the scalp is incised, the doctor needs to stop the bleeding of the incised scalp. Scalp clamps are commonly used hemostatic tools. Scalp clamps in traditional surgeries are used in conjunction with scalp clamps. The surgeon holds the scalp clamps and the instrument nurse clamps them. This will affect the speed of skin opening, and during the scalp clamping process, the amount of bleeding will increase due to the long operation speed and time. When the patient has high blood pressure, a lot of bleeding or the operation is in an emergency, it is easy to affect the progress of the operation, thereby threatening the patient's life. In addition, when the operation is in an emergency, if the surgeon and the instrument nurse do not cooperate closely, the instrument nurse's hands are easily injured by the scalp clamps, which increases the chance of infection for the instrument nurse, especially when operating on people with infectious diseases or infectious diseases, medical staff will be injured and susceptible to infectious diseases, increasing the occupational risk of occupational exposure.

[0003] Currently, there is a manual continuous firing disposable scalp hemostasis device on the market, which has many advantages for patients, such as less bleeding during surgery, less operation time, using instruments instead of manual work to reduce errors caused by manual work, avoiding infection, and fast postoperative functional recovery. However, during surgery, it is difficult to operate with one hand, the stability of the instrument is not good when working, and the speed of the instrument transmission is greatly affected by manual work. In particular, the grip strength of each person varies greatly, which can easily cause the instrument to not fire properly, the hemostatic clamp cannot accurately clamp the scalp, and affect the effect of the surgery.
