Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to the rongeur of a kind of lumbar intervertebral foramen mirror.
Background technology
Between original lumbar vertebra, rongeur does not have endoscope, the bad bone needing excision can not be aimed at accurately, mouth can not be begun to speak in appearance surgical work at organization internal needs of performing the operation because push rod is short, so just need out multiple hole, cause wound surface to strengthen, operation is painful, bleed too much.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of operation meticulousr, convenient, and when minimizing is performed the operation, location is inaccurate, the lumbar intervertebral foramen mirror rongeur of the misery of Repeated Operation and the loss of blood.
The purpose of this utility model has been come by following technical solution, the rongeur of this lumbar intervertebral foramen mirror, comprise push rod, claw beam, pull end and rear handle, endoscope is provided with in described rongeur, described claw beam inner sleeve has push rod, described push rod leading section is fixed with dynamic binding clip, and putting back-end portion is fixedly connected on the leading section of ram seat; Described claw beam leading section is fixed with determines binding clip, and this structure of determining binding clip is barb-like, and determines to combine in push-and-pull extrusion structure between binding clip and dynamic binding clip; The rearward end of described claw beam is placed in the leading section of claw beam seat, and the leading section of described ram seat is placed in the rearward end of claw beam seat, and ram seat overcoat has stage clip, and claw beam seat, stage clip and ram seat are placed in main body; Rear handle and this main body are fixedly connected, and rear handle is movably connected fixing by spiral shell axle and pull end, and the promote-side of this pull end contacts with the rearward end of ram seat.
As preferably, one end of described stage clip is limited in the rearward end of claw beam seat, and the other end of stage clip is limited on the ladder seat of ram seat.
As preferably, described claw beam and claw beam seat enchased part are provided with bath joint, and this bath joint is fixed on an end face of claw beam and claw beam seat.
The beneficial effects of the utility model are: with market similar products comparative benefits: 1, wound little, intervertebral can be entered by endoscope and blocks bad bone by single hole; Old product wound area is large, and need out multiple hole, production capacity completes excision bad bone; 2, push rod is longer than old product, and wound can be avoided to expand, and can enter organization internal operation, and it is meticulousr, convenient to operate; Old product push rod is short, can only expand wound like this, in appearance surgical work; 3, in endoscope with direction coordinate, belong to novel optical system, make to get a clear view during operation, binding clip can be determined by barb shape accurately and hook bad bone, promote push rod and allow to push away before binding clip and block bad bone rapidly, locate inaccurate when decreasing operation, the misery of Repeated Operation and the loss of blood.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, determine binding clip; 2, dynamic binding clip; 3, push rod; 4, claw beam; 5, claw beam seat; 6, bath joint; 7, main body; 8, ram seat; 9, rear handle; 10, pull end; 11, spiral shell axle; 12, stage clip.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to this utility model: as shown in Figure 1, this utility model comprises push rod 3, claw beam 4, pull end 10, rear handle 9, described claw beam 4 inner sleeve has push rod 3, described push rod 3 leading section is fixed with dynamic binding clip 2, and push rod 3 rearward end is fixedly connected on the leading section of ram seat 8; Described claw beam 4 leading section is fixed with determines binding clip 1, and this structure of determining binding clip 1 is barb-like, and determines to combine in push-and-pull extrusion structure between binding clip 1 and dynamic binding clip 2; The rearward end of described claw beam 4 is placed in the leading section of claw beam seat 5, and the leading section of described ram seat 8 is placed in the rearward end of claw beam seat 5, and ram seat 8 overcoat has stage clip 12, and claw beam seat 5, stage clip 12 and ram seat 8 are placed in main body 7; Rear handle 9 is fixedly connected with this main body 7, and rear handle 9 is movably connected fixing by spiral shell axle 11 and pull end 10, and the promote-side of this pull end 10 contacts with the rearward end of ram seat 8; Be provided with endoscope in described rongeur, this endoscope adopts high-quality stainless steel material, adopts optical glass, optical fiber, light dimension, belong to novel optical system, get a clear view, with direction sign, sapphire camera lens, never wornout in sight glass, belong to high temperature high voltage resistant disinfect endoscopes.
One end of described stage clip 12 is limited in the rearward end of claw beam seat 5, and the other end of stage clip 12 is limited on the ladder seat of ram seat 8.
Described claw beam 4 is provided with claw beam seat 5 enchased part joint 6 of washing by water, and this bath joint 6 is fixed on claw beam 4 with on an end face of claw beam seat 5.
