Description

Endoscope micro-wound instrument

Technical field

The utility model relates to the field of medical instrument technology, specifically, being a kind of endoscope micro-wound instrument.

Background technique

Breast enlargement is common one of beauty treatment.Secondary deformity and fibrous capsule contracture are the common of breast enlargement after breast enlargement Complication.Operative treatment is the main method and means for treating the above common complication.Wherein operating technology is related to fibrous capsule Lysis, the otomy of fibrous capsule, partly or completely total resection and fiber capsulorrhaphy of fibrous capsule etc..Routine of performing the operation approach It is to be completed through mammary areola or lower crease incisions.Armpit approach is common breast enlargement approach, but currently without related suitable instrument, Can not through armpit approach complete breast enlargement after secondary deformity operation and treatment.

There is scholar to describe and breast prosthesis leakage is completed using former notch pathway (armpit) and other two additional cut Fibrous capsule lysis after minimally invasive inspection and diagnosis and prosthese take out, operation are pulled open using scope drag hook and are protected under prosthese, row Fibrous capsule lysis in the case of fiber capsotomy, and protection prosthese, but not only operation difficulty is larger for these operating methods And it is extremely challenging, while tool there is limitations:

First, it needs to increase additional auxiliary incision, leads to more scar, scar hyperplasia influences body surface beauty.

Second, the treatment approach of secondary deformity generallys use mammary areola or lower pleat approach, existing instrument item after former breast enlargement Under part, surgical procedure is unable to complete successfully through armpit approach and obtains ideal effect.Simultaneously as China's breast enlargement is adopted mostly With armpit approach, secondary operation changes operative approach, while increasing scar again, is difficult to receive for many patients.So existing skill Art is usually to pass through breast areola approach or lower pleat approach completion surgical procedure, and armpit approach is in prior art condition and existing instrument It is unable to complete surgical procedure under cooperation, and obtains satisfied surgical effect.

Third, the prior art, since surgical procedure plane is bad, lack unity and coherence if do not operated in Microendoscopic, structure Inaccuracy is held, the appearance of some new postoperative complications and ill effect is frequently resulted in.

4th, armpit approach enters no matter on surgical procedure, or in tissue ductility compared with breast areola approach and lower pleat Road is more preferable, but existing surgical instrument is unable to satisfy technical requirements, can not obtain promising result.It is the blank spot of surgical instrument.

Chinese patent literature CN97248211.3, the applying date 19971103, patent name are as follows: a kind of breast humping device discloses one Kind care appliance more particularly to a kind of vacuum breast prominence apparatus.It includes cup and the pasties that are fixed in cup, and cup narrow end connects There is air intake duct, the air intake duct other end is communicated with vacuum suction, its main feature is that air intake duct is equipped with vent valve.On vacuum suction Equipped with vacuum degree regulator.Its vacuum degree is adjustable, and air can be put into cup by vent valve, so as to easily take Lower cup.But about a kind of modified endoscopic auxiliary under after armpit approach breast enlargement secondary deformity treatment surgical instrument group Close, establish the new approach of secondary deformity treatment and the new art formula through this approach after breast enlargement, facilitate it is more accurate, more efficient into Row operation, reduces operation wound and amount of bleeding, improves the control of surgical procedure, reduces postoperative complication, improves operative effect And patient satisfaction.Meet the technical solution of the new demand of accurate medicine then without corresponding open.

In conclusion under needing a kind of modified endoscopic to assist after armpit approach breast enlargement secondary deformity treatment surgical device Tool combination is established the new approach of secondary deformity treatment and the new art formula through this approach after breast enlargement, is facilitated more accurate, more efficient Carry out perform the operation, reduce operation wound and amount of bleeding, improve the control of surgical procedure, reduce postoperative complication, improve operation Curative effect and patient satisfaction.Meet the endoscope micro-wound instrument of the new demand of accurate medicine, and it is micro- about this endoscope Invasive procedures instrument yet there are no report.
