Puncture outfit for laparoscope

Abstract

The invention relates to the field of medical instruments, and discloses a puncture outfit for a laparoscope, the puncture outfit comprises a puncture rod assembly, a penetrating sleeve assembly and a sealing assembly, the puncture rod assembly comprises a puncture rod and a top cover, and the top cover is fixedly connected to one end of the puncture rod; the penetrating sleeve assembly comprises a penetrating sleeve and an adjusting valve, and the adjusting valve is fixedly connected to one end of the penetrating sleeve. the penetrating sleeve comprises a penetrating sleeve rod, a sealing end face, a first buckle and a Luer taper, the puncture rod is arranged in the penetrating sleeve rod in a penetrating mode, the sealing end face is arranged at one end of the penetrating sleeve rod, a through groove hole and a communicating hole communicated with the penetrating sleeve rod are formed in the sealing end face, and the first buckle is arranged at the end, away from the penetrating sleeve rod, of the sealing end face; the adjusting valve comprises a sealing shaft, the sealing shaft is rotatably arranged in the through groove hole in a penetrating mode, a vent hole is formed in the sealing shaft, and the vent hole is matched with the Luer taper and the communicating hole. The structure is relatively simpler, the sealing structure is optimized, and the sealing effect is better.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic trocar. Background technique [0002] The main purpose of the laparoscopic trocar is to penetrate the full thickness of the abdominal wall, establish a channel between the outside world and the abdominal cavity, and allow surgical instruments to enter the abdominal cavity through the trocar sheath to complete the surgical process and achieve the same purpose of open surgery. The puncture device is generally sterilized by irradiation before leaving the factory, and the product can only be used once. [0003] The existing abdominal puncture device is mainly composed of three parts: the puncture rod, the sealing valve and the puncture sleeve. Generally, the puncture rod, the sealing valve and the puncture sleeve are combined together, and the puncture sleeve is punctured from the human skin by the puncture rod. into the abdominal cavity, and establish art...

Problems solved by technology

[0004] Most of the current laparoscopic puncture devices have complex structures. For example, the patent application number CN201710438331.7 applied by Changzhou Ailon Precision Machinery Co., Ltd. discloses a laparoscopic puncture device with an improved sealing assembly, and its product contains as many as 20 parts. , including additional structures such as device fixing locks, rolling surfaces, and protective covers; the patent application number CN201420733456.4 applied by Changzhou Rockman Medical Devices Co., Ltd. discloses a trocar, which includes a handle assembly, a cannula assembly, a puncture 14 kinds of parts such as rods and ventilation components, and designed with removable sealing layer

Although the functions of the above-mentioned laparoscopic trocars are more complete, their structures are more complicated, the assembly is cumbersome, and the sealing effect is poor. They can be compatible with small
