Abstract
The utility model discloses a kind of perforator, comprise perforator, comprise puncture casing assembly and puncture needle assembly, thread a needle on the handle of assembly and be fixedly connected with under handle, central authorities are provided with through hole, it is characterized in that: described handle inside is provided with sight glass lock, and sight glass is locked and is provided with two joint pins, joint pin is stuck in the draw-in groove under handle, has at least on a joint pin and is provided with torsion spring.Due to the twisting force of torsion spring, after inserting endoscope's bar, make sight glass lock extruding endoscope bar, guarantee that endoscope position is relatively fixing, guarantee that in piercing process, imaging is stable.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of perforator with sight glass lockable mechanism.
Background technology
Disposable use microtrauma puncture device is the important apparatus in endoscope-assistant surgery, and it is that a kind of breast is outer, abdomen external cavity mirror instrument, is applicable to set up in thoracic cavity, chamber, abdominal cavity spectroscopy and operation process the apparatus of thoracic cavity, abdominal operation service aisle.When laparoscopic surgery starts, with scalpel, at the puncture position of choosing, cut epiderm skin, then with thread a needle part and the puncture casing transdermal enter body cavity of perforator, in this piercing process for fear of mistake penetration damage abdominal visceral browser, need to be by companion puncture in endoscope embedded puncture needle, because puncture needle head is transparent plastic material, so just can in piercing process, observe at any time by sight glass the situation of puncture.In prior art, the sight glass of perforator lock is arranged on the puncture handle with puncture needle, puncture handle is comprised of two parts, be on handle and handle under, on handle with under handle, with screw thread or snap fit, fix, sight glass lock is arranged on handle inside, can be to the through hole direction of handle central authorities and direction upset in opposite directions thereof, the sight glass that can insert in puncture needle via through holes to the upset of through hole direction plays certain fixation, but this sight glass lock is in a kind of free state, both affected apparatus attractive in appearance, and be unfavorable for again using.
Summary of the invention
This utility model is for above-mentioned deficiency, and providing a kind of had both increased the attractive in appearance of apparatus to inserting the fixed perforator of sight glass in perforator, guarantees that again in piercing process, imaging is stable.
The technical scheme adopting is: perforator, comprise puncture casing assembly and puncture needle assembly, on the handle of puncture needle assembly, be fixedly connected with under handle, central authorities are provided with through hole, it is characterized in that: described handle inside is provided with sight glass lock, sight glass is locked and is provided with two joint pins, and joint pin is stuck in the draw-in groove under handle, has at least on a joint pin and is provided with torsion spring.
The sight glass lock of perforator of the present utility model is stuck in the draw-in groove under handle by joint pin, on joint pin, cover has torsion spring, when sight glass inserts, sight glass is locked slightly to turning up, after insertion sight glass puts in place, unclamp sight glass lock, sight glass is locked in upset naturally under torsion spring twisting force, choke sight glass bar, sight glass is guaranteed that by locking in piercing process, imaging is stable.
Accompanying drawing explanation
Fig. 1 decomposing schematic representation of the present utility model;
Fig. 2 assembled state schematic diagram of the present utility model;
Fig. 3 partial structurtes schematic diagram of the present utility model (on handle, 22 have made biopsy cavity marker devices).
The specific embodiment
As shown in Figure 1-Figure 3, the puncture needle part of perforator of the present utility model, the Separator of organizing that comprises puncture needle tubing 1 and puncture handle 2 and front end, under the handle of puncture handle 2,21 are connected with puncture needle tubing 1, and on handle, 22 are fixed under handle on 21, and handle 2 central authorities that puncture are provided with through hole 23, under described handle, 21 are provided with sight glass lock 3, on sight glass lock 3, be provided with two joint pins 31, joint pin 31 is stuck in the draw-in groove 24 under handle, has at least on a joint pin 31 and is provided with torsion spring 4.During use, sight glass is locked to 3 a little to turning up, through hole 23 endoscope's bar 5 on handle is inserted in puncture casing 1, after putting in place, unclamp sight glass lock 3, sight glass lock 3 twisting forces due to torsion spring can inwardly push sight glass bar 5 by nature, in using perforator piercing process, endoscope is fixed position in perforator, guarantees that in piercing process, imaging is stable.
