Description
Technical Field

Background
Traditional treatments, such as surgery and medication, have gradually exposed some drawbacks over long periods of use. These are relatively coarse treatment modalities from the point of view of modern medical technology. For example, surgery must open a wound in the skin and may also injure tissues along the way. Traditional medicines are also used for entering blood circulation to act on the whole body, so that the traditional medicines belong to a treatment method with lower efficiency.
In addition, most of the traditional medicines ingested by swallowing pills or capsules are disposed of by the intestines and stomach, the liver, and only a small portion of the remainder enters the blood circulation, and finally a smaller portion of the small portion reaches the affected part. The physician therefore schedules the patient with a much higher amount of drug than the patient would eventually have. The excessive medicine amount inevitably brings various side effects to the patient, especially some medicines with larger side effects.
With the development of technology, more elaborate therapeutic approaches are being pursued. Such as minimally invasive, or even non-invasive, surgery to minimize trauma; such as precisely acting targeted drugs, targeted delivery, etc. Capsules are born under such a need. Due to the small enough overall size, targeted drug delivery can be achieved. The capsule is equipped with some manipulation mechanisms, such as miniature cameras, sampling needles, miniature sampling grips, etc., so that some fine operations can be performed.
For example, capsule endoscopes, which have been used in many hospitals, are used, and a patient swallows a capsule-sized endoscope, and the capsule endoscope completes a complete image of the entire length of the intestines and stomach along with the circulation of the intestines and stomach, and then the doctor checks the image. The capsule endoscope can complete the examination under the condition that the patient hardly perceives, thereby greatly relieving the pain of the patient. However, the existing capsule endoscope can only be used for detection, treatment cannot be completed, and accurate positioning cannot be realized.

The first external thread 11 and the internal thread 12 each have magnetism. In order to reduce the weight of the entire capsule, during the processing, the body of the housing 1 can be processed with plastic, and then nesting of the first external thread 11 and the internal thread 12 processed with magnetic material is nested on the outside and inside of the plastic, so that the first external thread 11 and the internal thread 12 are both magnetic. It should be noted that the housing 1 may also be directly processed by using a magnetic material, so as to ensure that the first external thread 11 and the internal thread 12 have magnetism, and a specific processing method is selected according to actual practice, which is not limited herein.
The tail end face of the shell 1 is provided with a micro-thorn 13, the top cover is provided with a through hole, the through hole is provided with a sampling needle 4, and the inner cavity of the sampling needle 4 is communicated with the inner cavity of the shell 1. In order to reduce the number of parts, the sampling needle 4 is integrally formed with the housing 1. The bottom of the side wall is provided with a first medicine outlet. The first medicine outlet is a plurality of first radial holes 14 uniformly distributed along the circumferential direction of the shell 1.
A sleeve 2 and a plunger 3 are arranged in the shell 1. Wherein the sleeve 2 is a cylinder with an opening at one end. The sleeve 2 is slidably connected to the housing 1. Specifically, the outer side wall of the sleeve 2 is provided with a rib extending along the axial direction, and the inner side wall of the shell 1 is provided with a chute 15 matched with the rib. Thereby, the sleeve 2 can be prevented from rotating when sliding. The inner side wall of the shell 1 is also provided with a ring groove 16, the head of the sleeve 2 is provided with a boss 21 matched with the ring groove 16, and the boss 21 can slide along the axial direction of the ring groove 16.

When the sleeve 2 moves to the bottom of the shell 1, the positions of the second radial holes 51 and the first radial holes 14 are in one-to-one correspondence, at this time, the medicine storage cavity 5 is communicated with the outside, and the plunger 3 pushes the liquid medicine in the medicine storage cavity 5 to flow out. The capsule after the installation was closed.
The working principle of the embodiment 1 of the application is as follows:
the medicine sampling integrated capsule capable of being driven to release is controlled by an external magnetic driving system, and the external magnetic driving system can apply forward and reverse rotating magnetic fields. The external magnetic drive system is prior art and will not be described in detail herein.
In order to reach the target position, the external magnetic control system applies a forward rotating magnetic field, the capsule rotates as a whole, and the capsule is screwed forward under the action of the first external thread 11 on the surface of the housing 1, and at this time, the forward trend of the plunger 3 in the housing 1 is also in the direction approaching the sampling needle 4, so that the liquid medicine is not squeezed at this time. After the capsule is moved entirely to the target site, tissue sampling or drug release may be selected. It should be noted that the tissue sampling and drug release operations may be completed sequentially, and the two operations may be completed only by tissue sampling or drug release operations.
If tissue sampling is performed, the external magnetic driving system is controlled to adjust the rotation direction of the magnetic field, so that the sampling needle 4 faces the sampling area, then the capsule is screwed forward until the sampling needle 4 pierces the tissue, then the magnetic field is rotated reversely, the capsule reversely rotates the sampling needle 4 to withdraw, and part of the tissue remains in the sampling needle 4, thereby completing the sampling operation.
If the drug release operation is performed, the magnetic field is required to rotate reversely. The capsule is reversed onto the nearby tissue wall and the micro-piercing 13 at the bottom of the capsule pierces the tissue, securing the housing 1. The magnetic field is then caused to continue to rotate in opposite directions, the plunger 3 inside the capsule being screwed in towards the bottom. Due to the incompressibility of the liquid in the drug storage cavity 5 the cartridge 2 will be pushed out first, the second radial holes 51 on the cartridge 2 being aligned with the first radial holes 14 on the housing 1. Then, the plunger 3 continues to be screwed into the bottom to slowly push the liquid medicine in the medicine storage chamber 55 out of the capsule, thereby completing the medicine release.
Example 2:
referring to fig. 2, an embodiment of the present application further provides a drivable drug delivery and sampling integrated capsule. The working environment is intestinal environment. Example 2 differs from the example only in that: in example 2, the sampling needle 4 was replaced with a sampling forceps 6. Specifically, the head of plunger 3 is equipped with actuating lever 7, and the head of shell 1 is equipped with stop collar 8, and actuating lever 7 stretches out behind the stop collar 8 and connects sampling clamp 6 away from the one end of plunger 3, and when plunger 3 axial motion, drive actuating lever 7, and then drive sampling clamp 6 closure completion sample. In order to reduce the number of components, the stop collar 8 is integrally formed with the housing 1.
The working principle of the embodiment 2 of the application is as follows:
the embodiment of the application can drive the drug-releasing and sampling integrated capsule to be controlled by an external magnetic drive system. The driving principle and the drug release principle are the same as those of example 1, and will not be described in detail here.
When tissue sampling is carried out, an external magnetic drive system is controlled to adjust the rotation direction of a magnetic field, so that the sampling forceps 6 are opened and fully embedded into the tissue, at the moment, the inside of the sampling forceps 6 contains tissue blocks, the outside of the sampling forceps 6 is wrapped by the tissue, then the magnetic field is reversely rotated, the traction force transmitted to the sampling forceps 6 by the plunger 3 can enable the sampling forceps 6 to be closed first, then, the capsule is continuously reversely driven due to the reduction of the resistance between the sampling forceps 6 and the tissue, and the sampling forceps 6 can be separated from the tissue, so that the sampling process is completed.
The present application is not limited to the above embodiments, and any changes or substitutions within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
