Abstract
The utility model provides a multiplex trocar for percutaneous puncture, belonging to appliances for transfusing media into a human body. The multiplex trocar for percutaneous puncture consists of a hollow needle1, a stylet 2 which can be inserted into the hollow needle1, a needle guard 3 which can be sheathed outside the hollow needle and a needle sheath 4 which can be sheathed outside the needle guard. The multiplex trocar for percutaneous puncture is used for the complex operations of minimally invasive surgery and percutaneous puncture for obtaining pathological diagnosis specimens. When the multiplex trocar for percutaneous puncture is used, puncturing is carried out at one point and then fine-to-coarse multiplex pore channel expansion is carried out under guidance, therefore, the multiplex trocar for percutaneous puncture can replace repeated puncturing on multiple parts and realize sequential multiple diagnoses and treatments carried out at the same part, thereby reducing tissue damage, enabling operations to be simple, convenient, quick, safe and accurate and meeting various clinical requirements.
Description
Technical field
This utility model belongs to the apparatus of medium being imported human body, is specifically related to a kind of multiple trocar of percutaneous puncture that is used to obtain pathological diagnosis specimen and Wicresoft's interventional therapy.
Background technology
Percutaneous puncture is that the doctor obtains the main means that the human pathology diagnoses specimen and carries out Wicresoft's interventional therapy, its objective is the occasional passage of setting up a derivation or introduction of substances between skin and diseased region.This special surgical technic is called as percutaneous puncture clinically.
The special utensil that carries out percutaneous puncture is called puncture needle.Usually be used to carry out the special operation of various objectives through the different size of specialized designs processing and the puncture needle of shape.As application number 02258786.1 " breast wears the bobbin assembly ", application number be 95209505.X's " punctio vesicae Air sac cover bobbin ", application number is 002067196 " a kind of thrombolytic paracentesis trocar ", 200710113347.7 utility model and patents of invention such as " disposable puncturing fistulization trocars ".
The sleeve pipe needle set of known all disclosed percutaneous punctures does not all relate to the multiple sleeve pipe needle set that can sequentially carry out multinomial diagnosis and treatment at present.Actual clinical when operation, when running into the multinomial diagnosis that needs same position and treatment, adopt different needle sets to repeat puncture at contiguous position more.Repeated puncture has caused that operation is complicated, risk is bigger, and the patient suffering is big, damage is big, and the malpractice that also causes vitals and tissue injury to cause when serious takes place.Therefore, how to design reasonable, safe, convenient, can sequentially carry out the percutaneous puncture needle set of multinomial diagnosis and treatment accurately, be a problem demanding prompt solution.
Summary of the invention
The purpose of this utility model provides a kind of multiple sleeve structure that has, and can sequentially carry out the percutaneous puncture needle set of multinomial pathological diagnosis and Wicresoft's interventional therapy.
The technical solution of the utility model is: the structure of the multiple trocar of percutaneous puncture by hollow needle, can insert hollow needle nook closing member, can be enclosed within the outer needle guard of needle body and can be enclosed within the outer stylophore of needle guard and form.Each part in four parts is made of body, blade and shank again.。
The needle body of hollow needle is that the metal tube of 0.5mm to 2.0mm processes by external diameter, and the front end of needle body becomes sharp-pointed needle point through grinding, at the root of needle body plastics or the metal needle handle that expands is set firmly.
The nook closing member body of nook closing member is made of through processing the tinsel that external diameter is slightly less than the hollow needle internal diameter, and the front end of nook closing member body can be processed into sharp-pointed needle point through methods such as grindings, at the root of nook closing member body plastics or the metal needle core handle that expands is set firmly.The length that the nook closing member body adds needle core tip equates with the total length of hollow needle.
The needle guard body of needle guard is processed by the metal tube that internal diameter is slightly larger than the hollow needle body diameter, and the front end of needle guard body can be processed into sharp keen needle guard sword through methods such as grindings, at the root of needle guard body plastics or the metal needle guard handle that expands is set firmly.The length of needle guard is less than the hollow needle body length.
The needle scabbard body of stylophore is processed by the metal tube that internal diameter is slightly larger than the needle guard body diameter, and the front end of needle scabbard body can be processed into sharp keen stylophore sword through methods such as grindings, at the root of needle scabbard body plastics or the metal stylophore handle that expands is set firmly.The length of stylophore is less than the total length of needle guard.
Before using operation nook closing member is inserted hollow needle from the needle handle end, embed the tissue blockage pin hole when preventing to implement puncture.Successively needle guard and stylophore are inserted in the root of hollow needle then from needle tip.
At first hollow needle is thrust patient part together with nook closing member with the suitable degree of depth when using operation, extract the part intervention injection that nook closing member can be implemented liquid medicine and preparation.
After this promote the needle guard handle, the outer needle guard of needle body is slided to the needle point direction under the guiding of needle body, thrust the suitable degree of depth of patient part, puncturing hole is enlarged.Make needle guard and human body relative fixed this moment, extracts hollow needle, can carry out the collection of biological tissue specimen.
Promote the stylophore handle afterwards, the outer needle guard of needle guard is slided to needle guard sword direction under the guiding of needle guard, thrust the suitable degree of depth of patient part, puncturing hole is further enlarged.Make stylophore and human body relative fixed this moment, extracts needle guard, can carry out such as various interventional therapys such as radio frequency, argon helium knife, particle implantation.
Because the enforcement of technique scheme makes to the utlity model has following advantage:
1, the process of using is simple and convenient, easy operating.
2, rational in infrastructure, processing technique is simple, and is with low cost, implements easily.
Few, the accurate positioning, safe and reliable of tissue injury can reduce the surgical medical risk greatly when 3, using.
4, a cover needle set can be implemented multiple Minimally Invasive Surgery treatment.
