Abstract
The utility model discloses a trocar for chemical ablation of cystic thyroid nodules, which comprises a needle sleeve, wherein a needle hole is arranged in the middle part of the needle sleeve, and a needle core is arranged in the needle hole; the needle sleeve is provided with a plurality of through holes near the tip, and the needle sleeve is provided with a syringe connecting port far away from the tip. This application reasonable in design designs the nook closing member 2 in needle cover 1, when inserting cystic tubercle, can in time take nook closing member 2 out, can be in time and effectual avoiding nook closing member 2 to wear broken bag wall, has avoided anhydrous alcohol or poly cinnamic alcohol to leak outward, and then avoids patient's pain or other severity consequences. The application ensures that the clinical operation is safer.
Description
Technical Field
The utility model relates to the technical field of medical treatment, specifically be a trocar that is used for cystic tubercle chemistry of thyroid gland to melt.
Background
At present, the cystic thyroid nodule is generally punctured by a hard steel needle of an injector, when liquid is gradually pumped out, the cystic thyroid nodule is gradually shrunk, the steel needle is easy to puncture the wall of the capsule, not only can the tissues around the nodule be damaged, but also the anhydrous alcohol or the lauromacrogol can be caused to overflow, and the pain and the discomfort of a patient can be caused. There is currently no trocar available for chemical ablation of cystic thyroid nodules.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a trocar for thyroid cystic nodule chemical ablation to solve the problem that provides among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a trocar for chemical ablation of cystic thyroid nodules comprises a trocar sleeve, wherein a needle hole is formed in the middle of the trocar sleeve, and a needle core is arranged in the needle hole; the needle sleeve is provided with a plurality of through holes near the tip, and the needle sleeve is provided with a syringe connecting port far away from the tip.
Further, the needle core is detachably arranged in the needle hole.
Furthermore, the needle sleeve is hollow cylindrical and one end of the needle sleeve is in a round table shape.
Further, the through holes are arranged around the cylinder in a circle and are not connected.
Compared with the prior art, the beneficial effects of the utility model are as follows:
this application reasonable in design designs the nook closing member in the needle cover, when inserting cystic tubercle in, can in time take the nook closing member out, can be in time and effectually avoid the nook closing member to wear broken bag wall, has avoided anhydrous alcohol or poly cinnamic alcohol, and then avoids patient's pain or other severity consequences. The application ensures that the clinical operation is safer.
Drawings
FIG. 1 is a block diagram of the present invention;
FIG. 2 is a schematic drawing of the fluid extraction process;
FIG. 3 is a schematic view of a liquid injection process;
in the figure: 1. a needle sleeve; 2. a needle core; 3. a through hole; 4. a syringe connection port; 5. a pinhole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
Referring to fig. 1, the trocar for chemical ablation of cystic thyroid nodules comprises a needle sleeve 1, wherein a needle hole 5 is formed in the middle of the needle sleeve 1, and a needle core 2 is arranged in the needle hole 5; the needle sleeve 1 is provided with a plurality of through holes 3 near the tip end, and the needle sleeve 1 is provided with a syringe connecting port 4 far away from the tip end.
When the ultrasonic puncture needle is used, the needle core 2 is inserted into the needle hole 5 of the needle sleeve 1, the needle is punctured into the cystic tubercle under the ultrasonic B positioning, and then the needle core 2 is taken out; as shown in fig. 2, a syringe connecting port 4 at the end of the needle sheath 1 is connected with a syringe or other suitable substitute, and the capsule liquid enters the needle sheath 1 from a through hole 3 at the tip of the needle sheath 1, and then the capsule liquid is extracted by the syringe. Subsequently, as shown in fig. 3, the sac cavity is flushed by reversely injecting physiological saline by a cleaned syringe according to the liquid drawing path, and then absolute alcohol or lauromacrogol is injected. After use, the trocar is pulled out.
Example two
Based on the first embodiment, the needle core 2 is detachably arranged in the needle hole 5, and the needle core 2 is made of stainless steel frosted sand to increase B-ultrasonic reflection.
EXAMPLE III
Based on the first embodiment, the needle sleeve 1 is hollow cylindrical and has one end in a truncated cone shape, and after the needle core 2 is pulled out, the truncated cone-shaped end of the needle sleeve 1 cannot damage the capsule wall.
Example four
Based on the first embodiment, the through holes 3 are arranged around the cylinder in a circle and are not connected, and the through holes are arranged in 360 degrees, so that the sac liquid can be sucked more conveniently; the liquid suction device can also be set to be a single hole type, and the liquid suction device can rotate to suck liquid, so that the phenomenon that the bag wall is not shrunk in time and the bag liquid cannot be sucked up is avoided.
This application reasonable in design designs the nook closing member 2 in needle cover 1, when inserting cystic tubercle in, can in time take out nook closing member 2, can be timely and effectually avoid nook closing member 2 to wear broken bag wall, has avoided anhydrous alcohol or poly cinnamic alcohol, and then avoids patient's pain or other severity consequences. The application ensures that the clinical operation is safer.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
