Integrated lighting and smoke-absorption knife pen

Abstract

The invention discloses an integrated lighting and smoke-absorption knife pen. The integrated lighting and smoke-absorption knife pen is characterized in that a knife pen control circuit is arranged on the upper layer of a knife pen shell, an operation electrode connector is arranged at the front end of the control circuit, and an operation electrode is connected with the control circuit through the operation electrode connector. A light-emitting diode (LED) lamp is arranged at the front end of a knife pen lower outer shell, the tail end of the control circuit is connected with a knife pen insert through a cable, and an electrotome control insert terminal and a light source power supply terminal are arranged at the front end of the knife pen insert. A smoke-absorption pipeline is formed in an inner cavity in the knife pen shell, a smoke-absorption port is formed at the front end of the knife pen outer shell, the tail end of the knife pen is connected with a narrow corrugated pipe in a sleeved mode, the narrow corrugated pipe is connected with a wide corrugated pipe through an adapter, the wide corrugated pipe is connected with a smoke adsorption device or the narrow corrugated pipe is connected with the smoke adsorption device directly through the adapter. The integrated lighting and smoke-absorption knife pen has the functions of lighting and smoke absorption.

Description

Technical field [0001] The invention relates to the field of electrosurgery equipment, and more specifically, is a medical surgical instrument that can cut tissues and coagulate blood during an operation after being connected to a host computer with an electrosurgery high-frequency electrode. Background technique [0002] Due to its superiority in function and operation, electrosurgical instruments are gradually replacing traditional scalpels. However, the electrosurgical pen will produce harmful fumes during the cutting and clotting process in electrosurgical operations. These surgical fumes can cause iatrogenic pollution and cause surgery. The pollution of the area is dangerous to patients and doctors, and it also affects the surgical field of vision. Therefore, it is necessary to use a smoking knife and a surgical smoke removal system to remove surgical smoke in order to eliminate iatrogenic pollution caused by surgical smoke. However, due to the lack of dedicated surgical smo...

Problems solved by technology

[0002] Due to the superiority in function and operation, electrosurgical instruments are gradually replacing traditional scalpels. However, the electrosurgical pen will produce harmful smoke during the cutting and coagulation process in electrosurgical operations. The iatrogenic pollution of these surgical fumes can cause surgery Regional pollution is dangerous to patients and doctors, and also affects the surgical field of view. Therefore, it is necessary to use a smoking knife and pen in conjunction with the surgical smoke removal system to remove surgical smoke during surgery, so as to eliminate the iatrogenic pollution caused by surgical smoke.

However, in view of the lack of special surgical smoke removal system and suitable smoking knife and pen in the domestic market, hospitals currently use negative pressure suction tubes for smoke removal. Doctors need others to hold negative pressure tubes to smoke while performing operations, resulting in untimely smoking. and the waste of personnel, and the sucked smoke has not been filtered and purified, and the purpose of completely removing harmful smoke cannot be achieved

However, other smoking pens currently on the market are thick and clumsy pens with a smoking pipe added on the basis of ordinary pens, so the doctor feels uncomfortable when holding the pen for surgery, and the operation is inconvenient, especially in narrow and deep surgery, which will affect the surgical field of vision.

In general, in order to act on different lesions and tissues, doctors need to replace surgical electrodes with different functions and different lengths. The lengthening of surgical electrodes increases the distance between the smoking port and the smoke source, which in turn leads to a sharp decrease in the smoking effect, and even no effect
