Minimally invasive scalpel for surgery

Abstract

The invention belongs to the technical field of medical instruments and discloses a minimally invasive scalpel for surgery. The scalpel comprises a scalpel head and a scalpel handle. The upper surface of the scalpel head is an arc surface. The front end of the scalpel handle is covered with the scalpel head. The junction between the scalpel head and the scalpel handle forms a scalpel point. The scalpel head is provided with an endoscope. According to the scalpel, tissue injuries to a patient can be reduced; meanwhile, as the endoscope and a negative-pressure suction port are both integrated on the scalpel, the accuracy of the surgery is improved, the effect of the surgery is good, the tissue injuries are less, and injury of the scalpel to medical workers can further avoided; furthermore, doctors can perform real-time visual monitoring during the surgery, so that surgical operation is more accurate, safer and more reliable; besides, destroyed diseased tissue or redundant tissue in the body of the patient can be sucked out in time.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a minimally invasive scalpel for surgery. Background technique [0002] Minimally invasive surgery is welcomed by the majority of patients because of its small trauma, light pain, quick recovery, and less scarring. However, due to the limitations of surgical equipment and medical conditions, surgery has high requirements for doctors. In the existing technology, the scalpels used in clinical surgery usually include a small needle knife and an ordinary scalpel. The small needle knife has a narrow head, a thin knife body, and insufficient strength. In addition, the knife body is short and small. Adjusting the direction, plus the need to cut and separate, can not achieve the purpose of the operation; the blade of the ordinary scalpel is wide, causing great damage to normal tissues, and is not suitable for minimally invasive surgery. Although the existing minimally invas...

However, due to the limitations of surgical equipment and medical conditions, surgery has high requirements for doctors

In the existing technology, the scalpels used in clinical surgery usually include a small needle knife and an ordinary scalpel. The small needle knife has a narrow head, a thin knife body, and insufficient strength. In addition, the knife body is short and small. Adjusting the direction, coupled with the need to cut and separate, can not achieve the purpose of the operation; the blade of the ordinary scalpel is wide, causing great damage to normal tissues, so it is not suitable for minimally invasive surgery

Although the existing minimally invasive surgery has a high degree of accuracy, can improve the operation effect and reduce tissue damage, its knife head is needle-shaped, which is very easy to cause damage to the fine parts of the patient, and it is also easy to cause inconvenience to the medical staff. Necessary injury, at the same time, when performing minimally invasive surgery, it is necessary to use other auxiliary observation instruments to observe the patient's body, and it is necessary to simultaneously extend the observation instrument and the scalpel into the patient's body at the same time, which increases the wound surface. It also increases the pain of the patient
