Description

A new type of length-adjustable laparoscopic electrosurgical knife

technical field

The utility model relates to the technical field of medical instruments, which is a novel length-adjustable laparoscopic electric scalpel.

Background technique

Laparoscopic surgery is a surgery performed using a laparoscope and its related instruments. Use a cold light source to provide illumination, insert the endoscopic lens (3-10mm in diameter) into the body cavity, use digital camera technology to make the image captured by the endoscopic lens transmit to the post-stage signal processing system through the optical fiber, and display it in real time on the dedicated monitor device. Then the operator analyzes and judges the patient's condition through the images of different angles of the patient's organs displayed on the monitor screen, and uses special endoscopic instruments to perform the operation. Laparoscopic surgery mostly uses 2-4 holes. Taking laparoscopic surgery as an example, one hole is opened slightly above the navel of the human body to avoid leaving long strips of scars on the patient's abdominal cavity. There are 1-3 linear scars of 0.5-1 cm left.

In the process of traditional laparoscopic surgery, there are the following problems: 1. During laparoscopic surgery, the length of the scalpel is fixed and cannot be adjusted according to needs; 2. Insufficient light and excessive depth of the body cavity lead to unclear images of the body cavity , which makes the operation time longer and affects the progress of the operation; 3. For organ operations on different parts (such as thyroid gland, breast, gallbladder), the length requirements of the endoscopic electric scalpel are different, but the overall length of the endoscopic electric scalpel is currently fixed. The operator needs to manually adjust to the optimal length and angle, which is time-consuming and labor-intensive, and extremely inconvenient.

To sum up, there is an urgent need for an endoscopic electrosurgical knife with fast operation progress, simple structure, convenient operation, and adjustable length, but there is no report about this endoscopic electrosurgical knife with adjustable length.

Contents of the invention

The purpose of the utility model is to provide a laparoscopic electrosurgical knife with fast operation progress, simple structure, convenient operation and adjustable length.

In order to achieve the above object, the technical scheme that the utility model takes is:

A novel length-adjustable endoscopic electrosurgical knife, characterized in that, the length-adjustable endoscopic electrosurgical knife includes an electric knife, a knife holder, a handle, and a display device; the electric knife is installed on the knife holder above; the front end of the knife handle is connected to the tool rest through a trapezoidal circular boss; the side wall of the boss is equipped with a cold light and a camera; the rear end of the knife handle is provided with a power display light, a power switch, and a knife rest adjustment button; the end of the knife handle is connected to the power line and the display device; the display device includes a data transmission line and a display; the inside of the knife handle is integrally connected with the light-emitting element and the image acquisition module; the The knife holder can be retracted into the knife handle.

The electric knife is installed on the knife holder through fastening screws, and the fastening screws can be screwed into the knife holder.

Both the knife rest and the knife handle are cylindrical in shape.

The overall length of the knife rest can be adjusted by the knife rest adjustment button.

The utility model has the advantages that:

1. A length-adjustable endoscopic electric scalpel of the present utility model further simplifies the operation and shortens the operation time on the basis of traditional endoscopic surgery, thereby improving the effect and efficiency of the operation, and is beneficial to the operation of the tissue in the body cavity;

2. The interior of the knife handle is integrated with the light-emitting element and the image acquisition module, which facilitates the monitoring and operation of deep tissues and shortens the operation time;

3. Adjust the extension length of the knife holder through the adjustment button of the knife holder, and reasonably control the position and angle of the scalpel, so that the operator can perform surgery more conveniently and effectively, improve the operation efficiency, and simplify the operation of the operation.

4. The length of the entire scalpel that can be inserted into the body cavity of the human body is about 35cm. There are integrated circuits such as light-emitting elements and image acquisition modules inside the handle, which can emit cold light, collect image information inside the body cavity, and output it on the monitor, making the exposure of deep tissue more clear and facilitating the smooth operation.
