The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail:
Embodiment one:
Embodiment as surgery instrument described in the utility model, as depicted in figs. 1 and 2, comprise support 1 and containing bag 2, described support 1 comprises hollow pipe 11 and handle 12, described handle 12 is located at hollow pipe 11 1 ends, offer through hole 121 on the described handle 12, described containing bag 2 comprises opening end and blind end, opening end is provided with the stay cord 3 that can tighten up opening end, the free end of described stay cord 3 is connected with pull head 4, described pull head 4 passes the through hole 121 on the handle 12, and is arranged on the handle 12, and the inner diameter values of described hollow pipe 11 is greater than the external diameter value of pull head 4.
In the present embodiment, described pull head 4 one ends are cylindric, and an end is cydariform grizzly bar 42, and the diameter value of described cydariform grizzly bar 42 external diameter maximums is greater than the inner diameter values of the through hole 121 of described handle 12, and less than the inner diameter values of hollow pipe 11.Described cydariform grizzly bar 42 diameter under situation about being stressed can diminish, be that gap between the grizzly bar 42 is compressible, and grizzly bar 42 has the power of reinstatement attitude, so can be placed in the through hole 121 of handle 12, when masterpiece is used for pull head 4, can overcome the frictional force of through hole 121 inwalls of handle 12 to pull head 4, enter hollow pipe 11 thereby break away from handle 12, cydariform grizzly bar 42 reinstatements this moment, and can pass hollow pipe 11.After the above operating procedure, described containing bag 2 in vivo, described pull head 4 is external, connects by stay cord 3 between the two, 4 couples of doctors of external pull head have the effect of caution, remind doctor's containing bag 2 also in vivo.
