Abstract
The invention discloses a puncturing device. The puncturing device comprises a puncturing sleeve assembly and a puncturing needle assembly. An upper handle part and a lower handle part of the puncturing needle assembly are fixedly connected, and a through hole is formed in the center of the puncturing needle assembly. The puncturing device is characterized in that a sight glass lock is arranged in a handle and provided with two connection columns, the connection columns are clamped in clamping grooves of the lower handle part, and at least one connection column is provided with a torsion spring. Through the torsion effect of the torsion spring, the sight glass lock extrudes an endoscope rod after the endoscope rod is inserted, and therefore the position of an endoscope can be fixed relatively, and the imaging stability in the puncturing process can be guaranteed.
Description
Technical field
The invention belongs to medical instruments field, be 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, the puncture position incision epiderm skin of choosing with scalpel, 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 made up of two parts, be on handle and handle under, on handle with under handle, fix with screw thread or snap fit, 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, play certain fixation to the through hole direction sight glass that can insert in puncture needle via through holes that overturns, but this sight glass is locked in a kind of free state, both affected apparatus attractive in appearance, and be unfavorable for again using.
Summary of the invention
The present invention be directed to above-mentioned deficiency, providing a kind of had both increased the attractive in appearance of apparatus to inserting the fixed perforator of sight glass in perforator, ensured 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 invention is stuck in the draw-in groove under handle by joint pin, on joint pin, cover has torsion spring, in the time that 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 ensured that by locking in piercing process, imaging is stable.
Brief description of the drawings
Fig. 1 decomposing schematic representation of the present invention;
Fig. 2 assembled state schematic diagram of the present invention;
Fig. 3 partial structurtes schematic diagram of the present invention (on handle, 22 have made biopsy cavity marker devices).
Detailed description of the invention
As shown in Figure 1-Figure 3, the puncture needle part of perforator of the present invention, comprise the Separator of organizing of 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.When 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 use perforator piercing process, endoscope is fixed position in perforator, ensures that in piercing process, imaging is stable.
