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

Abstract

The invention discloses a disposable puncture device, including a puncture sleeve, a sealing member, a puncture rod assembly and an intake assembly. The sealing member is arranged on the puncture sleeve. The sealing member is made of silica gel containing self-lubricant. The puncture rod assembly comprises a puncture rod base and a puncture rod, the puncture rod is an equal-diameter rod body, thetail end of the puncture rod is connected with the puncture rod base, and the head end of the puncture rod is contracted into a conical shape; The puncture rod is made of SUS304 material; The outer surface of the puncture rod is provided with a biodegradable self-lubricating coating. The disposable puncturing device of the invention improves the seal and the puncturing rod assembly in combination,has the self-lubricating effect, and can smoothly enter and exit the puncturing sleeve under the condition of ensuring the sealing performance of the seal, thereby enabling the puncturing rod and thesurgical instrument to enter and exit the puncturing sleeve.

Description

technical field [0001] The invention relates to a disposable puncture device, which is a laparoscopic 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 camera and v...
