Description

The two sacculus three chamber radiography treatment conduits of anterior angle controllable type

Technical field

This utility model is need not open breast with solving medically, drives under the situations such as abdomen the apparatus that human body lacuna or pipeline are diagnosed or treated, and belongs to the medical science surgery, fields such as interventional radiology.

Background technology

Medically often need do not carry out capital operation can be by comparatively conservative method, certain root conduit is inserted appointed part, further diagnose or treatment work by this conduit, inserting as the duodenal feeding tube behind the surgical operation promptly is by oral cavity or nasal cavity catheter proximal end to be inserted duodenum, because the gastrointestinal tract traveling is tortuous, the anterior direction of advance of existing conduit is wayward, so be difficult to successfully enter duodenum, often wastes time and energy.Behind some surgical operation abdominal cavity infection can appear and for example, at this moment just need percutaneous puncture insertion conduit under the situation of not opening abdomen, catheter proximal end is inserted infection place washes, inject antibiotics and drain, yet existing at present conduit all can not change the catheter proximal end direction of advance easily to adapt to body cavities traveling complicated and changeable, carry out next step diagnosis or treatment work and arrive appointed part quickly, so therapeutic effect is undesirable.

Summary of the invention

Thereby the purpose of this utility model a kind ofly can change the anterior angle of conduit arrives appointed part smoothly quickly under the seal wire guiding conduit according to the variation of position, the body cavities place direction of travel of required arrival easily with regard to providing, shorten the operating time, conduit arrive after the destination again can the A/C front end to prevent catheter displacement.

This utility model is by medical grade silicon rubber or/and the soft tubular structure that medical non-toxic plastic is made, mainly comprise: intermediary main chamber (1), the inferior chamber (2) of both sides, the conduit front part sides is separate, not connected sacculus (3), both sides time forward several gas injections in chamber, liquid hole (4), main chamber front aperture (5), the anterior side opening (6) in main chamber, main cavity rear end joint (7), inferior cavity rear end flap valve (8), chamber (9) is propped up at rear portion, main chamber, the primary and secondary chamber separates traveling point (10), a cavity rear end joint (11), position, sacculus place opacity thing indication place (12).Two not connected sacculus (3) are fixed on the anterior symmetric two side of conduit, can be by gas injection, liquid hole (4) gas injection in both sides sacculus (3) respectively in time chamber separately, fluid injection is to change the anterior angle of conduit, time chamber (2), both sides promptly is terminated to cecum near independently going ahead separately and walking to corresponding sacculus (3) front end tube wall attachment point, walk to walk to master chamber, both sides (1) backward, separately promptly separate with main chamber (1) tube wall at traveling point place inferior chamber (2).Catheter proximal end contracts thin so that advance slightly.Work process is as follows: by puncture technique or directly human body natural's tracts such as per os, nasal cavity catheter proximal end is sent into the near-end or the porch of required arrival tract, oral or through conduit master cavity rear end inject that contrast agent is being observed under the X line perspective or B-mode ultrasound tomography under the orientation and the traveling route direction of the required arrival tract of direct observation.Prop up chamber (9) by main chamber (1) or rear portion, main chamber and insert seal wire, make the soft head of seal wire near or exceed main chamber front aperture (5), this moment observes catheter proximal end or whether seal wire front end direction of travel is consistent with tube chamber traveling path, required arrival position and direction, as the unanimity seal wire that then directly advances, guide catheter advances, as inconsistent, then in this side sacculus (3), inject gas by a side time cavity rear end flap valve (8), liquid, fill big sacculus (3) with the bending conduit front portion, observe anterior the moving of conduit front portion and seal wire and reach direction of travel, as consistent with the direction of travel at required arrival position, then further insert seal wire, make the seal wire front end exceed catheter proximal end and advance, the seal wire front end then follows up conduit forward along seal wire after arriving certain position.As advancing, then extract gas, liquid in the sacculus (3) out, the follow-up conduit because of the sacculus (3) that expands hinders conduit.Position as seal wire front end direction of advance or catheter proximal end direction of advance and required arrival moves towards inconsistent, then the flap valve (8) by time cavity rear end changes sacculus (3) interior gas, amount of liquid, so that anterior angle trend of conduit or seal wire front end trend are consistent with required arrival position direction of travel.Moving direction and catheter proximal end direction of advance are opposite with the direction of travel at required arrival position if seal wire advances, and then extract the interior gas of sacculus (3), liquid out.In offside sacculus (3), inject gas, liquid gradually, this sacculus (3) expands gradually, make catheter proximal end oppositely become the angle when angulation makes catheter proximal end direction of advance and seal wire direction of advance move towards consistent with required arrival position, then stop injecting gas, liquid in this side sacculus (3), the seal wire that advances, when seal wire advanced to the seal wire front end and exceeds the catheter proximal end certain distance, conduit then followed up, so repeatedly, then catheter proximal end finally can successfully arrive destination.After arriving destination, to sacculus (3) in, inject a certain amount of gas or liquid, with the A/C front end or seal this body cavity and can not run off, be convenient to further diagnosis or treat to keep this body cavity interimage agent or medicine etc.Conduit master cavity rear end joint is connected with the apparatus tube chamber with diagnosis, treatment, closes a chamber, can further carry out Clinics and Practices by a cavity rear end joint (11).

This utility model advantage is: can control and adjust the anterior angle of conduit at any time by injecting gas or liquid in certain side sacculus (3) in the operating process, thereby can indicate seal wire to advance by required angle, direction, and then guide catheter advances, avoid seal wire not have blind the inserting in certain direction ground, reduced patient's misery, shortened the operating time, simultaneously can be after reaching the destination by in one or both sides sacculus (3), injecting a certain amount of gas or liquid A/C front end relative position, avoided external conduit rear portion to fix, both inaccurate also unbecoming.Can also expand sacculus, the closing body lumen near-end prevents losses such as the contrast agent that injected or medicine, is convenient to further diagnosis or treatment.
