Description

A kind of novel abdominal cavity puncture device

Technical field

The utility model relates to a kind of novel abdominal cavity puncture devices, belong to the field of medical instrument technology.

Background technique

The development of science and technology increasingly promotes medical instrument to be changed from open to minimally-invasive, and is applied by minimally-invasive medical instrument Capable Minimally Invasive Surgery because its have many advantages, such as wound is small, post-operative recovery it is fast just gradually by the vast line doctor of each department, hospital and The favor of patient.The successful application of laparoscope, thoracoscopic surgery techniques clinically with minimally invasive effect is abdominal cavity section, urological department The diagnosing and treating of equal departments' related disease provides technical support and guarantee, also plays for the progress of associated department clinical technology Very positive effect.

Clinically used casing punctures the routine side of often laparoscope and other mis instruments disengaging human abdominal cavity Method, abdominal cavity and thorax puncture outfit are the important tools for carrying out this work.This operation need to first with cutter in abdominal cavity of patients or Waist cuts out the mini-incision of several specified sizes, and then puncture outfit is pierced into notch Suitable depth, extracts inner core, then part into The puncture outer tube for entering human body chamber just establishes the channel of mis instruments disengaging human body.

, there is following technical problem mostly in the similar puncture outfit product in comprehensive market: after puncture cannula is combined with puncture needle, , need to be by other edge tools in human body suitable location aperture before imposing puncture, aperture is after the completion again by puncture outfit by wound position Piercing human body is set, this wound hole should not be too large also should not be too small, and excessive, puncture cannula is difficult to the stable and easy gas leakage in abdominal cavity, too small It is then pierced into that resistance is big, is pierced into that difficulty is big and have the risk for undermining internal organ, should not be controlled there are aperture size and complex steps Problem；Puncture cannula enters after abdominal cavity establishes channel, needs frequent movement, incision wound wall by the mis instruments passed through in the inner The puncture cannula stability for surrounding constraint is poor, brings obstacle to the smooth development of operation；The mis instruments of various outer diameter size When alternately entering puncture cannula, being limited to the factors such as material and the structure of air shuttle valve often causes it to generate a degree of leakage Gas phenomenon；Meanwhile puncture device assembly material kicks the beam or the overweight operating handle that will affect doctor.The technical program is intended to provide It is a kind of carry perforating cutter, in art good stability and appropriate in quality novel puncture device, it is general effectively to solve the similar puncture outfit in market Additional cutter need to be aided with all over existing above-mentioned aperture, phenomena such as puncture cannula stability is poor in art, gas leakage.
