Description

Hemorrhoid treating special-purpose needle head

Technical field

The present invention relates to technical field of medical instruments, more particularly, to a kind of hemorrhoid treating special-purpose needle head.

Background technology

Hemorrhoid are a kind of common diseases positioned at anus area, and any age can all fall ill, but with age, morbidity Rate gradually increases, in China, and hemorrhoid are most common anorectal diseases, have " ten male nine hemorrhoid ", the saying of " hemorrhoid of ten female ten "；Hemorrhoid are by hair The difference at raw position is divided into internal piles, external piles, mixed hemorrhoid, and asymptomatic hemorrhoid are not required to treatment, and Symptomatic hemorrhoid are without radical cure, with non-hand Based on art treatment, including topical therapy, oral drug therapy, injection treatment, physical therapy, plastic loop ligation etc., wherein, note Penetrate therapy to I, II degree of bleeding internal hemorrhoids effect preferably, its method be by injection of sclerosing agent around submucosa veniplex, make Cause inflammatory reaction and fibrosis, so as to press off the vein of varicose, treatment is repeated after January, but to avoid injecting curing agent Mucous layer causes necrosis；But the internal piles of deep place is pointed to, observation syringe needle is difficult to during injection and is pierced into depth, it is difficult entirely by groping To ensure therapeutic effect, if piercing is too deep or excessively shallow, adverse consequences can be all caused.

The content of the invention

The present invention is to be difficult to grasp piercing depth when carrying out hemorrhoid injection treatment to solve existing injection needle, and influence is controlled The problem of therapeutic effect, is safe and convenient to use there is provided one kind is simple in construction, is pierced into depth controllable, it is ensured that the hemorrhoid of therapeutic effect are controlled Treat special-purpose needle head.

To achieve these goals, the present invention uses following technical scheme：Hemorrhoid treating special-purpose needle head, including syringe needle sheet Body, spike body, which is provided with needle point, backshank, spike body, is provided with injection canal, and described spike body is provided with close to needle tip The piercing section that is sequentially connected, blocking section, linkage section, described piercing section axis are generally aligned in the same plane with linkage section axis, Described blocking section two ends are respectively with being pierced into section, the first bent angle of linkage section formation, the second bent angle.This programme sets in needle end and pierced Enter section, blocking section, form angle therebetween, so, after section piercing focus is pierced into, blocking section is because the presence of angle, just It is blocked in outside focus, can plays and prevent piercing section from continuing deeper into the work crossed submucosa and muscle layer and then pierce through intestinal wall With if while piercing section piercing depth not enough, can also not yet reach focus from external observation to blocking section；Linkage section is played Connecting needle is pierced into the effect of section, blocking section and backshank, and parenteral solution is transported to syringe needle by injection canal from backshank is pierced into section； First bent angle, the second bent angle are arc transition angle.

Preferably, described spike body length is 100-120 millimeters, described piercing segment length is 5-10 millimeters, Described piercing section is parallel with linkage section and spacing therebetween is 2-3 millimeters.The length that this programme is pierced into section can be according to hemorrhoid The size of sore focus is adjusted or selected.

Preferably, the angle of the first described bent angle, the second bent angle is more than 90 °.If hemorrhoid are larger, it is pierced into section and is pierced into It may go deep into not enough after focus, the bent angle for the larger angle that this programme is used can cause blocking section also can be suitable with adjustment angle And be pierced into the pin mouth that section pierces out and go successively to focus, the depth that increase syringe needle is pierced into, and linkage section can now play blocking section Effect, prevent be pierced into section it is excessively deep.

Therefore, the present invention has the advantages that：(1) it is simple in construction, it is safe and convenient to use；(2) it is pierced into depth controllable, Ensure therapeutic effect.

Brief description of the drawings

Fig. 1 is a kind of structural representation of the present invention.

In figure：1st, spike body 2, needle point 3, backshank 4, piercing section 5, blocking section 6, linkage section 7, the first bent angle 8th, the second bent angle.

Embodiment

The present invention will be further described below in conjunction with the accompanying drawings.

In embodiment as shown in Figure 1, hemorrhoid treating special-purpose needle head, including spike body 1, spike body 1 is provided with needle point 2nd, injection canal is provided with backshank 3, spike body 1, spike body 1 is provided with the piercing section 4 being sequentially connected, resistance close to the end of needle point 2 Compartment 5, linkage section 6, be pierced into the axis of section 4 be generally aligned in the same plane with the axis of linkage section 5, the two ends of blocking section 5 respectively with piercing Section 4, first bent angle 7 of the formation of linkage section 6, the second bent angle 8；

The length of spike body 1 is 100-120 millimeters, and it is 5-10 millimeters to be pierced into the length of section 4, is pierced into section 4 parallel with linkage section 6 And spacing therebetween is 2-3 millimeters；

First bent angle 7, the angle of the second bent angle 8 are more than 90 °.

Specifically used process is to be chosen according to hemorrhoid size of tumor and be pierced into the suitable injection needle of the length of section 4, use anal intestine Sem observation lesions position, by spike body 1 by anal intestine mirror close to focus, then by section 4 is pierced into is pierced into focus, is pierced into depth and passes through Observe blocking section 5 and the position of focus is determined, because the presence of the first bent angle 7, blocking section 5 can be blocked in outside focus, play Prevent be pierced into section 4 continue deeper into cross submucosa and muscle layer so that pierce through intestinal wall effect, parenteral solution by injection canal from Backshank 3 is transported to syringe needle 2 and is pierced into the injection focus of section 4；

If hemorrhoid are larger, be pierced into after section 4 is pierced into focus to go deep into not enough, and can adjust the angle of spike body 1 makes Blocking section 5 also can go successively to focus along the pin mouth that section 4 pierce out is pierced into, the depth that increase syringe needle is pierced into, and linkage section 6 because It for the presence of the second bent angle 8, can now play a part of barrier, prevent that piercing section 4 is excessively deep.
