Description

Cover Zha Quan pushes the trocar
Technical field
This utility model belongs to medical instruments field, particularly relates to a kind of cover Zha Quan and pushes the trocar.
Background technology
Under thoracoscope, utilize cover to prick snare and tie corresponding lung tissue, just can wipe out the lung tissue that cover is pricked far-end easily, finish the lung tissue biopsy; For bulla and bronchopleural fistula, prick the purpose that then can directly reach treatment by cover.Lung tissue is carried out the many places cover prick, can reach lung and subtract the appearance effect, can be used for emophysematous treatment.But, how will overlap Zha Quan and insert corresponding lung tissue, have not yet to see and carry out the relevant report that above-mentioned cover Zha Quan puts equipment.
At present in clinical, ligation treatment routine is used for hemostasis of gastroscope lower digestive tract mucosa vascular cuffing bundle and the excision of hemorrhoid cover bundle, when carrying out above-mentioned treatment, the placement of cover Zha Quan is by vacuum suction, pathological tissues is drawn in the hard pipeline, again that tube wall is outer cover Zha Quan is pulled to or is pushed into the root of the pathological tissues that is held, to play the effect of cover bundle.But by vacuum suction, generally can only hold a spot of tissue, prick the bigger comparatively difficulty of organizing for cover, in addition, thoracoscope and peritoneoscope are in operating process, generally all be to introduce operating theater instruments, and the trocar that uses at present is the metal tube with a nook closing member, can't plays the function that discharges cover Zha Quan by the trocar.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model will provide a kind of exactly can put the extremely cover Zha Quan propelling movement trocar of corresponding lung tissue with cover Zha Quan as required.
For achieving the above object, a kind of cover of this utility model Zha Quan pushes the trocar, comprise the guiding puncture nook closing member, inner sleeve, middle casing and trocar sheath, wherein, the guiding puncture nook closing member is the solid cylinder that an end has the taper needle point, inner sleeve, middle casing and trocar sheath are hollow cylinder, the guiding puncture nook closing member, inner sleeve, middle casing can be in the same place by mutual successively movable set with trocar sheath, have the syndeton that inner sleeve and trocar sheath flexibly connect on inner sleeve and the trocar sheath respectively, have the connecting device that middle casing and trocar sheath flexibly connect on middle casing and the trocar sheath respectively, the guiding puncture nook closing member is longer than inner sleeve, inner sleeve is longer than trocar sheath, the internal diameter of middle casing is slightly larger than the external diameter of inner sleeve, and the internal diameter of inner sleeve and the medical grasping tongs of organizing are complementary.
Further, described syndeton comprises ring for fixing that is fixed on the inner sleeve outer wall and the fixed bar that is fixed on the trocar sheath outer wall, the axis of ring for fixing and fixed bar is parallel with the axis of inner sleeve and trocar sheath, this ring for fixing and fixed bar are complementary, and have the latch-up structure that locks fixed bar on the ring for fixing.
Further, described latch-up structure is to be arranged on the screw that ring for fixing directly makes progress.
Further, described connecting device comprises ring for fixing that is fixed on the trocar sheath outer wall and the slide bar that is fixed on the middle casing outer wall, the axis of ring for fixing and slide bar is parallel with the axis of trocar sheath and middle casing, and this ring for fixing and slide bar are complementary, and has the locking mechanism that locks slide bar on the ring for fixing.
Further, described locking mechanism is to be arranged on the screw that ring for fixing directly makes progress.
Compared with prior art, this utility model cover Zha Quan pushes the trocar, the trocar and cover are pricked the circle pusher to be integrated, make the doctor thoracoscope and peritoneoscope trap prick organize more convenient, and, change the way of conventional vacuum suction fixing organization, and be designed to utilize organize grasping tongs directly vise and the tractive fixing organization in sleeve pipe, be convenient to overlap the bigger tissue of bundle, this equipment is not only simple in structure, and easy to operate.
Description of drawings
Fig. 1 is for originally being sleeved on inner sleeve, middle casing and outer sleeve structure sketch map (band cover Zha Quan) together;
Fig. 2 pushes the structural representation of the trocar for cover Zha Quan.
The specific embodiment
Among Fig. 1-2, cover Zha Quan pushes the trocar and is made up of guiding puncture nook closing member 7, inner sleeve 1, middle casing 2 and trocar sheath 3.Wherein, guiding puncture nook closing member 7 is a solid cylinder, the top of guiding puncture nook closing member 7 has taper needle point 8, tail end has top cover 11, inner sleeve 1, middle casing 2 and trocar sheath 3 are the hollow thin-wall metal canula, the internal diameter of inner sleeve 1 and the medical grasping tongs of organizing are complementary, the solid cylinder of guiding puncture nook closing member 7 is longer than inner sleeve 1, inner sleeve 1 is longer than trocar sheath 3, inner sleeve 1, middle casing 2 can be in the same place by mutual successively movable set with trocar sheath 3, guiding puncture nook closing member 7 is sleeved in the inner sleeve 1, and the internal diameter of middle casing 2 is slightly larger than the external diameter of inner sleeve 1.Inner sleeve 1 outer wall is provided with ring for fixing 5, ring for fixing 5 is provided with the screw 12 that can move radially along ring for fixing 5, a side is provided with ring for fixing 4 on trocar sheath 3 outer walls, opposite side is provided with fixed bar 9, have enough screws 13 that moves radially along ring for fixing 4 on the ring for fixing 4, middle casing 2 outer walls are provided with slide bar 10, the axis of ring for fixing 5, ring for fixing 4, fixed bar 9 and slide bar 10 is all parallel with the axis of inner sleeve 1, ring for fixing 5 is complementary with fixed bar 9, and ring for fixing 4 is complementary with slide bar 10.
