Abstract
The utility model relates to a sleeve tube soft leading filament type thoracic-abdominal puncture needle, which relates to a common medical puncture instrument. The utility model is provided with a hollow flexible leading filament in a needle cavity of a traditional thoracic-abdominal puncture needle. The outer diameter of the leading filament is equal to the inner diameter of the needle cavity. Meanwhile, a front hole of the needle cavity is closed; the lower part of a needle head is provided with the hole. Thus the soft leading filament is extended forwards along the needle cavity and is extended out from the hole at the lower part of the needle head, so and opening of the soft leading filament is positioned at a lever below the plane of the needle cavity. In this way, hydrops below the plane of the needle cavity can be pumped, and liquid sucking amount is increased under the condition of no reduction of puncture positioning points when the hydrops of the thoracic cavity is slightly little.
Description
This utility model relates to the puncture instrument in the medical apparatus and instruments.
The splanchnocoel puncture is one of main clinical means of pleural effusions and ascites, hematocele.The puncture needle of clinical practice at present is to connect one section flexible rubber hose behind No. 12, No. 16 the puncture needle.Its operational approach is to close flexible pipe tailing edge point of puncture with the hemostasis clamp to enter in the thoracic cavity, needs to extract syringe needle behind the drawing liquid by the state of an illness.Must be in when operation by two people operation, fixedly puncture needle or folder close puncture needle flexible pipe (or by injection container behind assistant's drawing liquid) to hold mosquito forceps by the assistant.Reference is " huang jiasi surgery " the 4th edition 1., Wu Jieping, Qiu Fazu chief editor, and the People's Health Publisher publishes.2. " diagnostics " third edition, the Qi Renduo chief editor, the People's Health Publisher publishes.
Said method has a bit not enough clinically: when treating less hydrothorax, because the localized point of puncture of B ultrasonic is central authorities of selecting hydrops, so when hydrops more after a little while, just stop drawing liquid when puncture needle is taken out not enough capacity hydrops because of the retraction of visceral pleura produces pain.
The purpose of this utility model is: when treating less hydrothorax, when not reducing puncture anchor point (because reducing the danger that the puncture anchor point can increase perforating wound visceral pleura and abdominal viscera), enter below the puncture needle plane and extract more hydrops with the soft seal wire of hollow in this utility model puncture needle chamber.
The technical solution of the utility model is as follows: it comprises the soft seal wire of needle body, handle and hollow.Preceding hole, its pin chamber is sealed and is punched below needle section.The profile of syringe needle can be an acute angle, can also be circular arc.Place the seal wire of the gentle silk of hollow at the pin intracavity, the external diameter of soft seal wire directly equates with the pin intracavity, soft seal wire can freely be protracted and the pin chamber is stretched out and downward traveling in the hole below needle section along the pin chamber.Soft seal wire can embed in the groove on handle fixing and can freely take out in the part behind the outdoor handle of pin chamber.Soft seal wire rear end connects syringe.
The utility model has the advantages that: owing in the pin chamber, placed the soft seal wire of hollow, it is out of shape downwards so soft seal wire stretched out from the hole of needle section below, make the opening of soft seal wire be positioned at the following level in plane, pin chamber, then the hydrops below the plane, pin chamber can be extracted out, increased the drawing liquid amount.
Fig. 1 is the front view of the soft seal wire type of sleeve pipe thoracico-abdominal puncture pricker.
Fig. 2 is that the A of the soft seal wire type of sleeve pipe thoracico-abdominal puncture pricker is to left view.
Fig. 3 is that the B-B of the soft seal wire type of sleeve pipe thoracico-abdominal puncture pricker is to profile.
2 is the hollow metal needle body among the figure, its sealing of front hole and perforate below needle section. Behind the needle body with length Side's body handle 3 is connected, and is carved with groove on the handle. Place the seal wire 1 of hollow flexibility in the pin chamber, outside it The footpath equates with pin chamber internal diameter. Soft seal wire 1 can embed the groove on handle in outdoor handle rear section, pin chamber In fixing and can freely take out soft seal wire rear end connection syringe. 4 is the clip on the soft seal wire.
Fig. 3 has illustrated that soft seal wire can embed fixing in the groove on handle and can freely take out.
Best implementation and operation of the present utility model following (accompanying drawings): at first give patient's puncture point orientation, then 1. with the soft seal wire 1 of hollow not extended needle subordinate side the hole and be retained in the pin chamber 2, simultaneously soft seal wire 1 is fixed in the groove on the handle, clip 4 closes state at folder.2. advance puncture needle to enter in the hydrothorax along the puncture anchor point, by the assistant with the fixing puncture needle of mosquito forceps.3. push ahead taking out the groove of soft seal wire 1 from handle, soft seal wire 1 along pin chamber 2 down crooked forward under the needle section square hole stretch out the pin chamber, make the opening of soft seal wire 1 be positioned at the following level in plane of needle body 2.Outdoor handle rear section, soft seal wire 1 pin chamber is fixed in the groove on the handle.4. soft seal wire 1 rear end connects syringe, opens clip 4 drawing liquid simultaneously, till extremely can not taking out repeatedly.Can suitably return a little needle body 2 to avoid injuring visceral pleura as pain.5. after folder closes clip 4, soft seal wire 1 taken out from groove be retracted into the pin intracavity, and soft seal wire 1 is fixed in the groove along pin chamber 2.6. extract the soft seal wire type of sleeve pipe thoracico-abdominal puncture pricker.
Claims (5)
1. the soft seal wire type of sleeve pipe pleura puncture needle, it comprises the soft seal wire of needle body, handle and hollow, it is characterized in that pleura puncture needle intracavity places the soft seal wire of hollow, soft seal wire can be protracted along the pin chamber and stretches out the pin chamber and traveling downwards from the hole of needle section below.
2. as the said thoracico-abdominal puncture pricker of claim 1, it is characterized in that the preceding hole sealing of pin chamber and perforate below needle section can be stretched out soft seal wire along this hole.
