Technical field:
The present invention relates to a kind of single-hole multi-channel laparoscopic surgical instruments, flat particularly to a kind of operation of single-hole multi-channel
Platform.
Background technology:
Single-hole multi-channel laparoscopic surgery incision operation platform have " multiple operating theater instruments entrances concentrate on simultaneously one put down
On platform " feature, multiple laparoscopic surgical instruments are imported by operation duct on platform and complete operation technique.Generally take
The little otch of umbilical part, but it is not limited solely to the minimally invasive laparoscopic surgery of umbilical part.
Single-hole laparoscopic surgery operating wound is little, pain light, it is fast to recover, beauty treatment advantage projects, and is Minimally Invasive Surgical Technology
Developing direction.But, current single-hole laparoscopic surgery apparatus is of less types and Shortcomings, forms apparatus because single hole operates
With apparatus, apparatus turnover parallel between hysteroscope so that work angle is difficult to be formed;In the case that light source is disturbed, operation
The visual field narrow compared with conventional laparoscopic operation field exposing it is impossible to meet the continuous demand for development of minimally invasive surgery new technique.
The promotion and application of single-hole laparoscopic technology have become the main flow of minimally invasive surgery, and operating platform is by porous single channel
Trend towards single-hole multi-channel.Research and develop new single-hole multi-channel laparoscopic surgery operating platform, by effective guarantee single hole abdomen
The clinical application of endoscope-assistant surgery, promotes Minimally Invasive Surgical Technology to develop further.
The content of invention:
The present invention is exactly the work angle in order to overcome operating theater instruments present in prior art to interfere outside abdominal cavity
It is difficult to be formed;In the case that light source is disturbed, many deficiencies such as operation field exposing narrow scope, a kind of structure letter is provided
List, convenient disassembly, the operation that interfering between operating theater instruments can be alleviated, effectively increase operating theater instruments of good sealing effect
Angle, can form the work angle meeting clinical needs and the Novel single-pore multichannel laparoscopic surgery operation of surgical field of view is flat
Platform.
