Description
Technical field
this utility model relates to medical instruments field, is specifically related to the intestines and stomach surgery, the laparoscopic surgery of Genneral Surgery, digestive endoscopy through Embryo nature tract endoscopic surgery equipment.
Background technology
laparoscopic surgery be clinical common one of surgically, existing laparoscopic surgery all needs use paracentesis trocar puncture abdominal cavity and place sleeve pipe in operation.Paracentesis trocar is generally made up of puncture needle and sleeve pipe two parts.
There is certain safety problem in current clinical conventional paracentesis trocar, due to the built-in taper shape of the sleeve pipe used at present or multiple-cutting-edge shape nook closing member diameter comparatively thick (10mm), most advanced and sophisticated sharp keen, when the stomach wall that punctures enters abdominal cavity, operator needs to use abundant clinical experience to judge dynamics and the degree of depth of puncture, as improper in the dynamics of puncturing or paracentesis trocar thrust dark, be easy to cause abdominal wall muscle, abdominal viscera or vascular tear, jeopardize patient vitals.Thus, prior art needs to improve.
Utility model content
The purpose of this utility model solves above defect, provides a kind of Novel laparoscope introducer
, laparoscopic cannula is imported and places the passage that stomach wall forms body surface and abdominal cavity, easy to use, safe and reliable, have a good application prospect.
The purpose of this utility model is achieved in the following ways:
A kind of Novel laparoscope sleeve pipe introducer, comprise introducer and be nested with the laparoscopic cannula on its surface, laparoscopic cannula one end is the insertion end for inserting abdominal cavity, the other end of laparoscopic cannula is handle end, handle end side is provided with gas control valve, and the cushion rubber mating with introducer and use is provided with in the inside of handle end, the inwall of introducer outer wall and cushion rubber is fitted tightly, one end of described introducer is for inserting portion, the other end is Handheld Division, portion of inserting is for conical, Handheld Division assembling laparoscopic cannula, described center, portion of inserting is provided with into thread eye, the cross-section center of Handheld Division is provided with out thread eye, enter thread eye and go out between thread eye and form passage, pass through for seal wire.Leading abdominal cavity fine needle aspiration, enter seal wire and expansion, then along seal wire, introducer is sent into abdominal cavity with being nested with together with the laparoscopic cannula of outer surface.
What deserves to be explained is, introducer is applicable to the laparoscopic cannula of clinical conventional 10mm, 8mm and 5mm diameter, by any diameter medical guiding wire with the use of.
In above-mentioned explanation, more preferred scheme, the Handheld Division of described introducer is cylindrical structural.
In above-mentioned explanation, more preferred scheme, the surface of described laparoscopic cannula is provided with some for anti-skidding groove, and the interval of adjacent two grooves is equal.When it prevents operation from carrying out, laparoscopic cannula on stomach wall outward cunning cause coming off.
In above-mentioned explanation, more preferred scheme, described in insert portion inside, front end be inlaid with metal tube, this metal tube be used for seal wire by time prevent silica gel tube from splitting.
The beneficial effect that this utility model produces is: compared with prior art, different techniques and methods is adopted to import laparoscopic cannula, laparoscopic cannula introducer adopts medical silica-gel to make, pliability is moderate, its front end pyramidal structure is applicable to expanding step by step, has seal wire to guide and can not damage abdominal viscera and blood vessel, solve the unexpected injury and complication that cause in peritoneoscope piercing process, improve the safety of operation, there is important clinical meaning.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of introducer in this utility model embodiment;
Fig. 2 is the combination schematic diagram of this utility model embodiment introducer and laparoscopic cannula;
In figure, 1 is introducer, and 2 is laparoscopic cannula, and 3 is gas control valve, and 4 is passage, and 5 for inserting portion, and 6 is Handheld Division, and 7 is metal tube, and 8 is groove.
concrete enforcement
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail.
The present embodiment, with reference to Fig. 1 ~ Fig. 2, is mainly used in laparoscopic surgery and through Embryo nature tract endoscopic surgery.It specifically implements the laparoscopic cannula 2 comprising introducer 1 and be nested with on its surface, laparoscopic cannula 2 one end is the insertion end for inserting abdominal cavity, the other end of laparoscopic cannula 2 is handle end, handle end side is provided with gas control valve 3, and be provided with in the inside of handle end and mate with introducer 1 cushion rubber used, the inwall of introducer 1 outer wall and cushion rubber is fitted tightly, one end of described introducer 1 is for inserting portion 5, the other end is Handheld Division 6, insert portion 5 for conical, laparoscopic cannula 2 is assembled in Handheld Division 6, described center, portion 5 of inserting is provided with into thread eye, the cross-section center of Handheld Division 6 is provided with out thread eye, enter thread eye and go out between thread eye and form passage 4, pass through for seal wire.
The Handheld Division 6 of described introducer 1 is cylindrical structural.The surface of described laparoscopic cannula 2 is provided with some for anti-skidding groove 8, and the interval of adjacent two grooves 8 is equal.When it prevents operation from carrying out, laparoscopic cannula 2 on stomach wall outward cunning cause coming off.The described inside, front end inserting portion 5 is inlaid with metal tube 7, this metal tube 7 for seal wire by time prevent silica gel tube from splitting.Compared with prior art, its structure is simple, and the overall silica gel that adopts is made, and has stronger flexibility, can free bend, is easy to use, has a good application prospect.
Operational approach is: leading abdominal cavity fine needle aspiration, enter seal wire and expansion, along seal wire, introducer 1 is sent into abdominal cavity with being nested with together with the laparoscopic cannula 2 of outer surface again, exit introducer 1 and leave laparoscopic cannula 2, laparoscopic cannula 2 placed by application of sleeve introducer 1.There is the advantage preventing the unexpected severe complication such as the abdominal viscera that occurs or vascular tear because using traditional sleeve puncture needle, drastically increasing the safety of operation, there is important clinical meaning.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as protection domain of the present utility model.
