Problems solved by technology

When the puncture rod is in contact with the lubricating component, the sharp structure of the front part of the puncture rod will damage the medical elastic porous material, especially after the puncture rod or surgical instrument has been punctured many times, the damage is more serious. The broken porous material is prone to debris, and the debris enters the human body is dangerous
In addition, choosing medical silicone oil as a lubricant will cause the sealing components made of silicone material to dissolve with silicone oil, which will damage the sealing performance of the trocar
[0010] It can be seen that the above-mentioned disclosed patents do not solve the resistance problem well, and thus need to continue to improve

Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

[0022] see figure 1 with figure 2 , the most preferred embodiment of the present invention, a trocar for laparoscopic surgery, comprising a puncture sleeve 3, a seal 2, a puncture rod assembly 1 and an air intake assembly 4, the seal 2 is arranged on the puncture sleeve 3, and the puncture The rod assembly 1 includes a piercing rod base 11 and a piercing rod 12. The piercing rod 12 is an equal-diameter rod body, and the tail end of the piercing rod 12 is connected to the piercing rod base 11. The head end of the piercing rod 12 shrinks into a polygonal pyramid. After passing through the sealing member 2, the head end is inserted into the puncture sleeve 3, and the base 11 of the puncture rod is clamped on the puncture sleeve 3. The air intake ass...

Abstract

The invention discloses a puncture outfit for endoscope surgery. The puncture outfit comprises a puncture sleeve, a sealing element, a puncture rod assembly and an air inlet assembly. The sealing element is made of silica gel containing a lubricant. The puncture rod assembly comprises a puncture rod base and a puncture rod. The puncture rod is a diameter-consistent rod body. The tail end of the puncture rod is connected with the puncture rod base. The head end of the puncture rod shrinks to form a multi-edge conical shape. The head end of the puncture rod penetrates through the sealing elementand is then inserted in the puncture sleeve. The puncture rod is made of a medical high-polymer material containing an acid amide lubricant. The acid amide lubricant is made of oleamide, and the content of oleamide accounts for 1% of the total mass of the medical high-polymer material. By the combined improvement of the sealing element and the puncture rod assembly, the puncture outfit for endoscope surgery has a self-lubricating function, and the puncture rod and a surgical instrument can smoothly enter and leave the puncture sleeve under the condition of ensuring the sealing performance ofthe sealing element.

Description

technical field [0001] The invention relates to a puncture device for laparoscopic surgery, which is a laparoscope matching surgical instrument and is suitable for establishing a working channel during laparoscopic examination and operation. Background technique [0002] With the development of medicine and the improvement of people's health awareness, laparoscopic surgery is playing an increasingly important role in minimally invasive surgery due to its advantages of less trauma, faster recovery, less postoperative pain, and shorter hospital stay. The clinical application of minimally invasive surgery advocated is becoming more and more extensive. [0003] The principle of laparoscopic surgery is to use carbon dioxide gas to create an artificial pneumoperitoneum as an observation and operation space; use a puncture device to puncture several small holes of 0.5-1.0 cm in the abdominal wall to establish a channel between the abdominal cavity and the outside world; There are ...
