Abstract
A kind of disposable celiac mirror bile duct puncture attracts pin; comprise a root puncture pin; puncture needle front end is provided with puncturing head; rear end is connected with plastics backshank, is provided with passage in puncture needle, is also provided with passage in plastics backshank; the outside of puncture needle is arranged with a protecting tube; the length of protecting tube is greater than the length of puncture needle, and the rear end of plastics backshank is connected with a resilient bladder, the channel connection in the inner chamber of resilient bladder and plastics backshank.In laparoscopic biliary tract operation process, by Trocar hole, protecting tube is inserted abdominal cavity together with puncture needle and resilient bladder, pull out protecting tube at intraperitoneal, extrude resilient bladder in advance, utilize puncture needle to carry out bile duct puncture; Discharge resilient bladder after puncture, bile sucks by resilient bladder, and puncture needle is reinserted protecting tube, exits abdominal cavity.This utility model solves the easy damaging surrounding tissue of normal injection syringe needle and shifts out the more difficult technical problem in abdominal cavity, easy to use, do not need separately otch and puncture stomach wall.
Description
Technical field:
This utility model relates to mankind life article.Particularly relate to medical apparatus and instruments, particularly choledochoscope clamper, particularly a kind of disposable celiac mirror bile duct puncture attracts pin.
Background technology:
Need to draw bile as cultivation and pathologic finding material in laparoscopic biliary tract operation process.Its process be cut common bile duct, distinguish anatomical structure after normal injection syringe needle is inserted intraperitoneal, clamp this normal injection syringe needle and the common bile duct that punctures with laparoscopic instrument, then cut gallbladder pipe with electric knife; Need if desired to carry out gallbladder pipe decompression by this normal injection syringe needle simultaneously.Easy damaging surrounding tissue in abdominal cavity and clipping operation inserted by normal injection syringe needle, and it is more difficult to shift out abdominal cavity.
Summary of the invention:
The purpose of this utility model is to provide a kind of disposable celiac mirror bile duct puncture to attract pin, the easy damaging surrounding tissue of normal injection syringe needle that described this disposable celiac mirror bile duct puncture attracts pin will solve in prior art to adopt when puncturing common bile duct in laparoscopic biliary tract operation and shift out the more difficult technical problem in abdominal cavity.
This disposable celiac mirror bile duct puncture of the present utility model attracts pin, comprise a root puncture pin, the front end of described puncture needle is provided with puncturing head, the rear end of puncture needle is connected with a plastics backshank, passage is provided with in puncture needle, also passage is provided with in described plastics backshank, passage in puncture needle from described puncturing head extend back and with the channel connection plastics backshank, wherein, the outside of described puncture needle is arranged with a protecting tube, the length of described protecting tube is greater than the length of puncture needle, the rear end of plastics backshank is connected with a resilient bladder, a thin neck is provided with between plastics backshank and described resilient bladder, the inner chamber of resilient bladder is by the passage in thin neck and the channel connection in plastics backshank.
Further, the front end of protecting tube is closed, front end outer wall spherically shape or the parabolic shape of protecting tube.
Further, the external diameter of protecting tube is less than or equal to the external diameter of plastics backshank, and the external diameter of thin neck is less than the external diameter of plastics backshank, and the external diameter of resilient bladder is less than or equal to the external diameter of plastics backshank.
Further, the shape of protecting tube rear end face and the form fit of plastics backshank front end face.
Further, protecting tube rear end face is the taper shape of indent.
Operation principle of the present utility model is: in laparoscopic biliary tract operation process, by the Trocar hole being based upon stomach wall, protecting tube is inserted abdominal cavity together with puncture needle wherein and resilient bladder, pull out protecting tube at intraperitoneal, utilize puncture needle to carry out bile duct puncture judgement under peritoneoscope; Extrude resilient bladder in advance before puncture, after puncture, discharge resilient bladder, during resilient bladder resilience, bile is sucked, puncture needle is reinserted protecting tube, exit abdominal cavity by Trocar hole.
This utility model is compared with prior art, and its effect is actively with obvious.This utility model is at the outer sheathed protecting tube of puncture needle, resilient bladder is connected after puncture needle, in laparoscopic biliary tract operation process, by the Trocar hole being based upon stomach wall, protecting tube is inserted abdominal cavity together with puncture needle wherein and resilient bladder, pull out protecting tube at intraperitoneal, utilize puncture needle to carry out bile duct puncture judgement under peritoneoscope; Extrude resilient bladder in advance before puncture, after puncture, discharge resilient bladder, during resilient bladder resilience, bile is sucked, puncture needle is reinserted protecting tube, exit abdominal cavity by Trocar hole.This utility model solves the easy damaging surrounding tissue of normal injection syringe needle and shifts out the more difficult technical problem in abdominal cavity, easy to use, do not need separately otch and puncture stomach wall.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that disposable celiac mirror bile duct puncture of the present utility model attracts pin.
Fig. 2 is the structural representation that disposable celiac mirror bile duct puncture of the present utility model attracts the puncture needle in pin.
Detailed description of the invention:
Embodiment 1:
As depicted in figs. 1 and 2, disposable celiac mirror bile duct puncture of the present utility model attracts pin, comprise a root puncture pin 1, the front end of puncture needle 1 is provided with puncturing head, the rear end of puncture needle 1 is connected with a plastics backshank 2, passage is provided with in puncture needle 1, also passage is provided with in plastics backshank 2, passage in puncture needle 1 from puncturing head extend back and with the channel connection plastics backshank 2, wherein, the outside of puncture needle 1 is arranged with a protecting tube 3, the length of protecting tube 3 is greater than the length of puncture needle 1, the rear end of plastics backshank 2 is connected with a resilient bladder 4, a thin neck 5 is provided with between plastics backshank 2 and resilient bladder 4, the inner chamber of resilient bladder 4 is by the passage in thin neck 5 and the channel connection in plastics backshank 2.
Further, the front end of protecting tube 3 is closed, front end outer wall spherically shape or the parabolic shape of protecting tube 3.
Further, the external diameter of protecting tube 3 is less than or equal to the external diameter of plastics backshank 2, and the external diameter of thin neck 5 is less than the external diameter of plastics backshank 2, and the external diameter of resilient bladder 4 is less than or equal to the external diameter of plastics backshank 2.
Further, the shape of protecting tube 3 rear end face and the form fit of plastics backshank 2 front end face.
Further, protecting tube 3 rear end face is the taper shape of indent.
The operation principle of the present embodiment is: in laparoscopic biliary tract operation process, by the Trocar hole being based upon stomach wall, protecting tube 3 is inserted abdominal cavity together with puncture needle 1 wherein and resilient bladder 4, pull out protecting tube 3 at intraperitoneal, utilize puncture needle 1 to carry out bile duct puncture judgement under peritoneoscope; Extrude resilient bladder 4 in advance before puncture, after puncture, release resilient bladder 4, sucks bile during resilient bladder 4 resilience, puncture needle 1 is reinserted protecting tube 3, exit abdominal cavity by Trocar hole.
