Description
Technical field
This utility model relates to a kind of Mini-type puncture outfit, and it belongs to medical apparatus and instruments, is mainly applicable in the laparoscopic surgery of human body.
Background technology
In prior art, human abdominal cavity operation widely uses perforator, is particularly used in Minimally Invasive Surgery field and laparoscopic surgery.Common perforator comprises thimble assembly, the gentle valve component of needle assembly, thimble assembly and needle assembly clamping; Because the sleeve pipe in thimble assembly and sleeve pipe lower cover are split-type structurals, clamping is needed between the gentle valve component of thimble assembly, this just make between sleeve pipe and sleeve pipe lower cover and Joining Technology between the gentle valve component of thimble assembly complicated, it is convenient not to assemble, cost is high, also easily causes chronic leakage.
Utility model content
Technical problem to be solved in the utility model to overcome in prior art existing above-mentioned deficiency, and provide a kind of structural design more rationally, simpler, the better Mini-type puncture outfit of sealing effectiveness of technique.
The technical scheme in the invention for solving the above technical problem is: this Mini-type puncture outfit comprises thimble assembly, the gentle valve component of needle assembly of hollow, thimble assembly and needle assembly clamping, it is characterized in that: described thimble assembly comprises sleeve pipe, sleeve pipe lower cover, sleeve pipe upper cover, inner seal liner and outside seal, described sleeve pipe and sleeve pipe lower cover are integral type structure, inner seal liner and outside seal are all between sleeve pipe and sleeve pipe upper cover, and sleeve pipe lower cover is connected by pin close-fitting with sleeve pipe upper cover.Make the Joining Technology of this utility model between sleeve pipe and sleeve pipe lower cover simpler thus, assemble more convenient, cost is lower, and sealing effectiveness is better.
Air valve body assembly described in the utility model and sleeve pipe and sleeve pipe lower cover are connect by gluing, and make technique simpler, assemble more convenient, cost is lower.
This utility model compared with prior art, has the following advantages and effect: structural design is more reasonable, and because sleeve pipe and sleeve pipe lower cover are integral type structure, not only make Joining Technology simpler, assemble more convenient, cost is lower, and sealing effectiveness is better.
