Electric needle capable of flushing and sucking

Abstract

The flushing and sucking electric needle includes one electric needle body comprising electric needle coated with insulator and power source joint in the tail of the electric needle; and one hollow suction device jacketing the electric needle body and connected to the electric needle body detachably and hermetically via tail connecting part. The suction device has one set of separated blocks in the inner wall at the other end to support the electric needle body in the center of the suction device. One T-valve has one end connected to the outlet in the side wall of the suction device, the other end connected to negative pressure sucking pipe and the third end connected to washing liquid pipe, and can make the space between the suction device and the electric needle body communicated with the negative pressure sucking pipe or the washing liquid pipe. The electric needle can eliminate mist and excessive liquid timely to provide clear operation environment and clean wound.

Description

technical field [0001] The invention relates to a medical instrument for laparoscopic surgery, in particular to an electric needle for surgery. Background technique [0002] In recent years, laparoscopy has been widely used in the field of surgical medicine at home and abroad. Electroacupuncture is an indispensable instrument in laparoscopic surgery. It produces a lot of smoke when cutting tissues. These smoke will block the surgical field of view. In the past, only through The abdominal puncture trocar on the abdominal wall is used to discharge the smoke, but this method has the following disadvantages: 1. The smoke discharge is slow, and the recovery of a clear surgical field of view is also slow; Elevate the abdominal wall to expose the abdominal distension gas of the surgical field of view, resulting in the collapse of the abdominal cavity, which gradually reduces the surgical space and is not conducive to the exposure of the surgical field of view, which increases the d...

[0002] In recent years, laparoscopy has been widely used in the field of surgical medicine at home and abroad. Electroacupuncture is an indispensable instrument in laparoscopic surgery. It produces a lot of smoke when cutting tissues. These smoke will block the surgical field of view. In the past, only through The abdominal puncture trocar on the abdominal wall is used to discharge the smoke, but this method has the following disadvantages: 1. The smoke discharge is slow, and the recovery of a clear surgical field of view is also slow; Elevate the abdominal wall to expose the abdominal distension gas of the surgical field of view, resulting in the collapse of the abdominal cavity, which gradually reduces the surgical space and is not conducive to the exposure of the surgical field of view, which increases the difficulty of the operation for the operator and easily causes accidental injury; 3. Through the switch of the puncture trocar Exhausting smoke is to directly discharge the smoke from the patient's body and expose it to the air. Long-term inhalation of these smoke will have adverse effects on the health of the operator
