Abstract

A kind of Multifunction percutaneous renal puncture of this utility model pin belongs to medical instruments field, be made up of needle body and nook closing member, it is characterized in that: described needle body is provided with needle point, slide calliper rule, interface from top to bottom, described needle body has also portrayed scale, can clear display puncture penetration depth.Described needle point designs becomes frosted shape, to strengthen ultrasonic reflection, is beneficial to B ultrasonic location.Described needle body is also provided with screw thread, and have screw thread in distance needle point 5cm distance needle body surface design, scale mark place avoids.Described slide calliper rule are nut type, and the inside of slide calliper rule is provided with screw thread equally, by cooperatively interacting with the screw thread on needle body, can rotate the position that paracentesis depth is fixed in migration up and down.This utility model is under the prerequisite reaching effectively puncture effect, avoid puncturing in art dark, B ultrasonic location difficulty, the problems such as complex operation, effective reduction venipuncture difficulty, avoiding puncturing in art causes bleeding deeply, the complication such as visceral organ injury, be applicable to Urology Surgery Percutaneous Nephrotithotomy rubble lithotomy, can sterilize and reuse.

Description

A kind of Multifunction percutaneous renal puncture pin
Technical field
A kind of Multifunction percutaneous renal puncture of this utility model pin belongs to medical instruments field.
Background technology
Universal along with calculus invasive methods, Percutaneous Nephrotithotomy rubble lithotomy has become the clinical common surgical of Urology Surgery at present, and the key of the success or not of Percutaneous Nephrotithotomy to be rubble get stone, is also the maximum operating procedure of risk.The problem such as postoperative hemorrhage in clinical normal generation puncture failure, art, needs to stop operation, Interventional Hemostasis, even open resection kidney or hemorrhagic shock dead etc., its basic reason is to puncture and deeply injures renal blood vessels, or repeatedly repeated puncture passage is hemorrhage etc.So how effectively to control paracentesis depth in clinical, instruction puncture direction etc. becomes the problem needing solution badly.And the common percutaneous renal puncture pin of current clinical middle employing, exist and indicate without scale, be difficult to during puncture accurately hold the degree of depth, the problems such as needle tip B ultrasonic location difficulty.Although the patents such as existing CN201603242U, CN202699243U, CN201603242U make improvement to above-mentioned shortcoming, effect still owes desirable, is still difficult to effectively control paracentesis depth, the problem such as location difficulty under needle point B ultrasonic.The reason that there are these shortcomings is: 1, needle body is without obvious graduation indication; 2, avoid puncturing without device dark; 3, needle point tiny smoothly ultrasonic be difficult to visit and etc.
Utility model content
In order to avoid the deficiencies in the prior art, this utility model provides a kind of Multifunction percutaneous renal puncture pin, and this utility model structure is simple, easy to use, effectively can control paracentesis depth, ensures puncture effect.
The purpose of this utility model is reached by following measures, a kind of Multifunction percutaneous renal puncture pin is made up of needle body and nook closing member, described needle body is provided with needle point, slide calliper rule, interface from top to bottom, described needle body has also portrayed scale, can clear display puncture penetration depth.
Described needle body is provided with screw thread, and become screw thread, long 10cm in distance needle point 5cm distance needle body surface design, scale mark band place avoids not establishing screw thread.
Described slide calliper rule are nut type, and the inside of slide calliper rule is provided with screw thread equally, and by cooperatively interacting with the screw thread on needle body, the position of slide calliper rule is fixed in rotatable upper and lower migration, according to paracentesis depth needs, rotate slide calliper rule up and down to desired depth, for limiting paracentesis depth.
Described needle point designs becomes frosted shape, and frosting is about 1cm, can increase ultrasonic reflection signal, ultrasonic probe is more easily visited and, convenient location and instruction puncture direction, can increase penetration Resistance again, improve puncture feel
This utility model is a kind of Multifunction percutaneous renal puncture pin of a kind of Urology Surgery, under the prerequisite reaching effectively puncture effect, avoid puncturing in art dark, B ultrasonic location difficulty, the problems such as complex operation, effectively reduce venipuncture difficulty, avoid puncturing in art and deeply cause bleeding, the complication such as visceral organ injury, are applicable to the simple Percutaneous Nephrotithotomy of Urology Surgery or rubble lithotomy, can sterilize and reuse.
Accompanying drawing explanation
Accompanying drawing 1 is needle body schematic diagram of the present utility model.
Accompanying drawing 2 is nook closing member schematic diagrams of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1. needle point, 2. needle body, 3. scale, 4. screw thread, 5. slide calliper rule, 6. interface, 7. nook closing member.
As shown in accompanying drawing 1-accompanying drawing 2, this utility model is made up of needle body 2 and nook closing member 7, described needle body 2 is provided with needle point 1 from top to bottom, slide calliper rule 5, interface 6, described needle body 2 has also portrayed scale 3, can clear display puncture penetration depth, described needle body 2 is also provided with screw thread, screw thread 4 is designed on the surface at distance needle point 5cm needle body, screw thread face length 10cm, scale mark pillar location is avoided not establishing screw thread, described slide calliper rule are nut type, the inside of slide calliper rule is provided with screw thread equally, by cooperatively interacting with the screw thread on needle body, rotatable upper and lower migration is with instruction, fixing paracentesis depth.
This utility model embodiment:
Be expert at percutaneous deep puncture fistula-building time, first use B ultrasonic localizing objects renal calices, after measurement needs paracentesis depth, rotate and regulate slide calliper rule to the many about 0.5cm of corresponding scale, load onto nook closing member, puncture omnidistance B ultrasonic clear location tip position, guided puncture direction and the degree of depth, after arriving the set degree of depth, namely slide calliper rule run into skin and stop that making puncture needle be difficult to continuation gos deep into, and extracting nook closing member suction has urine sucking-off to point out puncture to put in place.
The above is only this utility model optimal application case, and technical solutions of the utility model are not limited thereto, and can also be used as other medical use liquids and collect purposes.Use this utility model or under secondary enlightenment, make other equivalent modifications and improvement, claims of the present utility model should be considered as.
