Problems solved by technology

[0003] The new type of laparoscopic surgery is performed by modern high-tech medical technology using advanced equipment principles such as electronics and optics. It is an era-changing progress of traditional laparotomy. Therefore, it is easy to cause damage to the patient's abdominal skin, and the laparoscopic surgical instrument is also likely to scratch the inner wall of the patient's abdominal cavity in the abdominal wall

Embodiment

[0030] Embodiment: After the tube needle 6 is inserted into the patient's abdominal cavity, the protective pad 5 is in contact with the patient's abdominal skin, and the telescopic rod 9 and the spring 10 can provide a certain buffer force, so that the patient's abdomen will not be contacted by the installation cylinder 1 , to avoid pressing and rotating the installation cylinder 1 to cause imprinting or damage to the patient's abdomen. Operate the handle 2 and the wrench 3 to control the opening and closing of the fixed chuck 7 and the movable chuck 8. When the fixed chuck 7 and the movable chuck 8 are closed, the tissue or foreign matter to be removed can be clamped and fixed, and the barbed groove The cooperation of 71 and barb head 81 can make the tissue or foreign matter clamped more firmly without slipping, and the protective ball sleeve 19 can effectively protect the inner wall of the patient's abdominal cavity from being scratched. After the filter filter 12 and the LE...

Abstract

The invention relates to the field of laparoscopic surgery, and particularly relates to an individual operation type laparoscopic surgical instrument structure. The laparoscopic surgical instrument structure comprises a mounting cylinder, a mounting sleeve box and a tubular needle. A handle and a wrench are arranged at the bottom of the mounting cylinder. The mounting cylinder is internally provided with a CCD photosensitive element, an image acquisition card, a storage battery and a connection processor. The CCD photosensitive element, the image acquisition card, the storage battery, the connection processor and a USB interface are electrically connected in sequence. The mounting sleeve box is arranged on one side of the mounting cylinder. One end of the mounting sleeve box is connected with an elastic corrugated pipe of which the other end is connected with a protection pad. The tubular needle is arranged at the end, close to the mounting sleeve box, of the mounting cylinder. The tubular needle penetrates through the protection pad. The protective pad is in contact with the abdominal skin of a patient. A telescopic rod and a spring can provide given buffering force, so that the abdomen of the patient cannot be in contact with the mounting cylinder, thereby avoiding compression injury to the abdomen of the patient due to compressive rotation of the mounting cylinder.

Description

technical field [0001] The invention relates to the technical field of laparoscopic surgery, in particular to a single-operated laparoscopic surgical instrument structure. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these three channels; and then spe...
