A minimally invasive scalpel for surgical operations

Abstract

The invention belongs to the technical field of medical instruments, and discloses a minimally invasive scalpel for surgery, which includes a knife head and a handle. A knife edge is formed at the joint of the handle, and an endoscope is arranged on the knife head. It can reduce the tissue damage of the patient. At the same time, the endoscope and the negative pressure suction port are integrated on the scalpel, so that the accuracy of the operation is improved, the operation effect is good, the tissue damage is less, and the injury of the scalpel to the medical staff can be avoided. It allows doctors to conduct real-time visual monitoring during the operation process, making the operation more accurate, safe and reliable, and it can also timely suck out the damaged lesions or excess tissue in the patient's body.

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
