Abstract

The utility model relates to an auxiliary device used for matching ordinary single pipe inner endoscope during inner endoscope operation, which belongs to the iatrical devices technology field. The utility model comprises an outer cover pipe (1) and an inner cover pipe (2) which are joined together. The inner cover pipe which can be made of flexible nylon plastics, is longer than the outer cover pipe, and the shape of the front end of the inner pipe is arc bending. Once extending out of the outer cover pipe, the shape of the inner pipe is bending, and the length of the extending out parts is adjusted by the gear-like adjuster (5) fixed on the stomata of the outer cover pipe via the rack (8) fixed on the stomata of the inner cover pipe; the direction of the arc bending is adjusted by the spiral tooth-profile (9) via the gear-like uplift (11) fixed on the inner cover pipe. During operation, the utility model is tied to the inner endoscope and inserts into the body of patients, and the operation devices reach the operation parts via the pipe of the inner endoscope and the inner cover pipe of the auxiliary device. The length of the extending out parts of the inner cover pipe and the direction of the arc bending is adjusted and the relative position is the best so as to ensure the smooth of the implementation of the operation. The utility model has the advantages that the price is cheap, the conformation is reasonable, the usage is simple and flexible and the effect is excellent; not only the flexibility and accuracy of the operation are increased, but also the medical cost decreased.

Description

The endoscopic surgery assistor

Technical field:

This utility model relates to the medical apparatus technical field, is a kind ofly to be used to cooperate common one-pipe scope to carry out the assistor of endoscopic surgery, cooperatively interacts and finishes under the scope comparatively complicated operations so that operating theater instruments arrives operative sites by two pipelines.

Background technology:

When under scope, finishing as operations such as early stage canceration excision, mucosa stitchings, need to adopt twin flue scope, but common scope has only an apparatus pipeline, if replace with two one-pipe scopes with two biopsy pipelines, then can increase complication, bring misery to patient.The twin flue scope of existing import, it costs an arm and a leg, and uses restrictedly, and owing to two pipelines lean on too closely, operates dumbly, and cooperation acquires a certain degree of difficulty.

Summary of the invention:

This utility model provides a kind of operation assistor for existing common one-pipe scope, it mainly is an auxiliary pipeline, both be equivalent to the twin flue scope when cooperating the operation of scope person combined surgery, again because the improvement on the assistant structure makes this match ratio twin flue scope come more nimbly and freely.For ease of narration, introduce accompanying drawing earlier.

This utility model endoscopic surgery assistor is formed by trocar sheath 1 and inner sleeve 2 fits.At external end, the trocar sheath mouth of pipe is connected with a circular base 3, and a side of pedestal 3 is provided with a passage parallel with trocar sheath 4, and gear-like actuator 5 is installed; Inner sleeve mouth of pipe place is provided with two tube walls between eaves 10, two eaves and is provided with diagonal dentation protuberance 11, and annulus 6 is embedded between two eaves, is fastened by two semicircular rings to form; Spiral groove actuator 9 is installed, this actuator and dentation protuberance 11 couplings, scalable inner sleeve 1 is clockwise or be rotated counterclockwise.Tooth bar 8 is installed on the below of annulus 6, places in the passage 4, and tooth bar 8 is complementary with gear-like actuator 5, so that inner sleeve is vertically regulated.Inner sleeve 2 is long than trocar sheath 1, elastic material such as available nylon, front end is convexly curved, in case stretch out trocar sheath, will be bending, its length of stretching out trocar sheath is regulated by tooth bar 8 with gear-like actuator 5, its arc-shaped bend towards then regulating by dentation protuberance 11 with gear-like actuator 9.During operation, this utility model and scope are held together in the (see figure 2) insertion body, operating theater instruments arrives operative site by the pipeline and the assistor inner sleeve of scope respectively, regulate length that inner sleeve stretches out and arc-shaped bend towards making two kinds of operating theater instruments be in best relative position, thereby it is smooth to perform the operation.This utility model is cheap, and is rational in infrastructure, easy to use flexible, effective, both increased the motility and the accuracy of operation, reduced medical expense again.

The specific embodiment:

Embodiment 1: this utility model trocar sheath 1 long 1000mm, external diameter 4.0mm, internal diameter 3.5mm; Circular base 3 external diameter 20mm, the external diameter coupling of internal diameter and trocar sheath, thickness 12mm; Tooth bar 8 long 60mm, cross section 4 * 2 (mm); Passage 4 cross sections are rectangle, long 6mm, and wide 3mm, gear-like actuator 5 external diameters are 5mm, groove and tooth bar 8 couplings.Inner sleeve 2 long 1060mm, external diameter 3.2mm, internal diameter 2.7mm; Eaves 10 thick 3mm, wide 5mm, two eaves are at a distance of 5mm; Annulus 6 external diameter 16mm, internal diameter 3.5mm, thickness are 5mm, actuator 9 external diameters are 5mm, diagonal dentation protuberance 11 couplings on its helical form groove and the tube wall.
