Endoscope usually has a long and narrow channel, and the slender surgical instrument can reach the lens position through the channel, so as to complete the operations such as clamping, sampling and cutting. In some cases, we also need to carry out positioning, detection, drug delivery or radiotherapy at a specific position in the human body.

However, the prior art lacks a load unit specially designed for endoscope instrument. Because the channel aperture of the endoscope is small, and the wire / rod structure connected to the tail end of the tissue clamp needs to be extended to the other end of the channel during the closing action of the clamp. Therefore, it is difficult for those skilled in the art to directly load enough load on the tissue clamp. In view of the above, those skilled in the art need a load unit specially designed for endoscope instrument. SUMMARY

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the problem that there is a lack of load unit specially designed for endoscope instrument in the prior art, which makes it difficult for medical workers to transport and fix enough load in the patient's body.

[0025] The technical scheme of the utility model has the following advantages:

[0026] 1. The load unit for an endoscope provided by the utility model comprises:

[0027] A load cavity, which has a cavity for accommodating circuit elements, drugs or radioactive sources;

[0028] A clamping portion arranged on the load cavity; the clamping portion is adapted to a tissue clamp so that the tissue clamp clamps the clamping portion and fixes the load cavity in a patient's body.

[0029] In the utility model, a medical endoscope can be used to reach some difficult-to-reach positions in the human body through natural cavities or artificially established holes, thereby achieving the functions of diagnosis and treatment. The endoscope usually has a long and narrow channel, and a slender surgical instrument can reach the position of the lens through the channel to complete clamping, sampling, cutting and other operations. In some special cases, medical workers need to perform positioning, drug delivery or radiotherapy at specific positions in the human body. Compared with performing the above operations by means of surgery, using an endoscope to reach the position has the advantage of less damage. At present, endoscopic instruments have ready-made tissue clamps (soft tissue clamps are also called titanium clamps, hemostatic clamps, etc.) for hemostasis or wound closure. The soft tissue clamp can be inserted into the channel and clamped and fixed to the corresponding position. In the utility model, the tissue clamp sends the corresponding load unit to the specified position through the channel of the endoscope and fixes the load unit.

[0030] However, due to the small diameter of the channel of the endoscope, the wire / rod structure connected to the tail end of the tissue clamp needs to be extended to the other end of the channel when the clamp is controlled to open and close. Therefore, it is difficult for those skilled in the art to directly place sufficient load on the tissue clamp. Moreover, there is a lack of load units specially designed for endoscopic instruments in the prior art, which makes it difficult for medical workers to transport the load unit through the endoscopic instrument.

[0031] To address the aforementioned technical issues, the present invention provides a loading chamber for accommodating circuit components, sensors, medications, or radioactive sources. Furthermore, a clamping portion is provided on the loading chamber. This clamping portion is adapted to fit within a tissue clamp, allowing the clamp to grip the clamping portion and secure the loading chamber within the patient's body.

[0032] 2. In the load unit for an endoscope provided by the present invention, when the load cavity is used to accommodate drugs, the load cavity is a porous structure, an openable structure or a degradable structure to achieve the release of drugs.

[0033] In the present invention, by configuring the loading chamber to be an openable structure or a degradable structure, the above configuration can facilitate medical workers to administer medicine to a designated location in the patient's body.

[0034] 3. The load cell for an endoscope provided by the present invention has a central portion of the load chamber connected by a snap-fit ​​structure, forming a switchable upper and lower load chamber portions. The cavity formed by the upper and lower load chamber portions is used to accommodate medication. The snap-fit ​​structure may be a concave-convex buckle structure, a connecting thread structure, a hook-and-hook structure, or the like. This snap-fit ​​structure allows medical personnel to easily and effectively open the load chamber, thereby releasing the medication contained therein.

[0035] 4. The load unit for an endoscope provided by the present invention has a load cavity that is a cylindrical structure.

[0036] In the present invention, the load chamber can also be configured as other external structures as needed, such as a rectangular parallelepiped, a cube, a strip structure, etc. The shape of the load chamber is preferably a cylindrical structure. The cylindrical load chamber can ensure that the cross-sectional area of ​​the load chamber is maximized when passing through the same endoscopic channel constraints, which is conducive to accommodating loads such as circuit components, drugs, or radioactive sources inside the load chamber.

[0037] 5. In the load unit for an endoscope provided by the present invention, the clamping portion is arranged at the end position of the load cavity and is adapted to the tissue clamp.

[0038] In the present invention, the clamping portion can be arranged at other positions of the loading chamber as needed. The clamping portion is preferably arranged at the end position of the loading chamber, so that medical workers can conveniently clamp the clamping portion with a tissue clamp, transfer the loading chamber and fix it in the patient's body.

[0039] 6. The load unit for an endoscope provided by the present invention has the clamping portion being a circular ring structure.

[0040] In the utility model, the clamping part can also be a structure other than a ring, such as a triangular ring or a polygonal ring. In the utility model, the clamping part is preferably provided as a ring structure because the through hole area of the ring structure is the largest, which is beneficial to the passage of the tissue clamp. In the use process, the load cavity can be implanted through the endoscopic channel, and the clamping part of the ring structure can be held by a metal clamp and further firmly and reliably fixed in the patient's body.

[0041] 7. The utility model provides a load unit for endoscope, the load cavity is the positioner for containing circuit element;

[0042] The outer surface of the load cavity is wrapped with a material that is transparent and meets the biocompatibility requirements; the load cavity is provided with:

[0043] The light emitting element emits light to indicate the lesion position;

[0044] The transduction mechanism in the load cavity corresponds to the transmitter, and the transmitter provides relay energy for the transduction mechanism through a wireless power transmission mode; the transduction mechanism is connected to the light emitting element and supplies power to the light emitting element; the wireless power transmission mode includes electromagnetic induction type power transmission, magnetic resonance type power transmission, wireless wave type power transmission and electric field coupling type power transmission.

[0045] In the utility model, the load cavity contains circuit elements as positioners. The positioners can be used for preoperative positioning of the gastrointestinal tract and other functions. By setting the outer surface of the load cavity as a transparent material, the light of the light emitting element can effectively pass through the transparent outer shell and accurately indicate the lesion position for the doctor. Moreover, the good biocompatibility of the shell material can effectively avoid the risk of direct contact of electronic elements with the human body and the problem of damage to electronic elements caused by direct contact with digestive fluids.

[0046] More importantly, in the utility model, the transmitter provides relay energy for the energy conversion mechanism through wireless power transmission, and then the energy conversion mechanism supplies power to the light emitting element. The wireless power transmission is also called wireless power transmission or non-contact power transmission, which refers to the transmission mode of converting electric energy into other forms of relay energy, such as electromagnetic field energy, laser, microwave and mechanical wave, through a transmitter, and then converting the relay energy into electric energy through an energy conversion mechanism after transmission in the air for a distance, so as to realize wireless power transmission. Among them, the wireless power transmission can effectively realize the power supply for the light emitting element by adopting electromagnetic induction type, magnetic resonance type, wireless wave type, electric field coupling type and the like. Since the positioner needs to pass through the endoscope channel with a diameter less than 4mm, the size of the positioning lamp is severely limited. Moreover, under the limitation of the size and structure, the miniature battery cannot achieve 24h lighting of the LED lamp. Therefore, the battery in the prior art is difficult to realize mass production from the aspects of production process, cost and practicability. In the utility model, the positioner is powered through wireless power transmission, which effectively realizes that the light emitting element of the positioner has sufficient lighting time and brightness while meeting the requirement that the positioner can pass through the endoscope channel with a diameter less than 4mm.

[0047] In the utility model, the use method of the load unit for preoperative positioning of the gastrointestinal tract comprises the following steps:

[0048] Step S1, within a specified time before surgery, let the patient have a gastroscopy or enteroscopy examination. During the examination, the endoscope doctor finds the lesion to be removed through the gastrointestinal endoscope equipment.

[0049] Step S2, the doctor uses the endoscope to push the load unit as the positioner in the utility model into the vicinity of the lesion through the endoscope forceps channel, opens the tissue clamp, makes the clamp arm pass through the clamping part of the load cavity, and then clamps the mucosa near the lesion. If necessary, the tissue clamp can be increased for reinforcement. In the utility model, one or more of the above positioners can be used for positioning at the same lesion position according to the need.

[0050] Step S3, open the transmitter in the utility model near the patient's abdomen, and observe and confirm the light emission of the light emitting element of the positioner under the endoscope. At this time, the transmitter can also be moved slowly. With the change of the position of the transmitter, the brightness of the light emitting element observed under the endoscope changes correspondingly. In the above process, the doctor finds the position of the transmitter corresponding to the maximum brightness of the light emitting element and marks it on the body surface, so as to roughly determine the body surface projection position of the lesion and assist the surgeon in determining the surgical incision.

[0051] In addition, in the utility model, the patient can also be examined by X-ray before surgery. Since the transmitter and the tissue clamp can be developed, they can also help the surgeon to determine the lesion position before surgery.

[0052] And, in the surgical process, the medical worker opens the above-mentioned transmitter near the patient's abdomen, the transmitter does not have to contact the sterile table, at this time the light emitted by the locator transmits through the digestive tract wall and is seen by the operating surgeon, so that the positioning in the operation is completed.

[0053] Step S4, the doctor removes the locator, tissue clamp and tumor lesion together through operation.

[0054] 8. The load unit for an endoscope provided by the utility model, the wireless electric energy transmission mode is magnetic resonance type electric energy transmission;

[0055] The transducing mechanism comprises a power receiving coil and a capacitor, the light emitting element, the capacitor and the power receiving coil are arranged in parallel, a magnetic core for increasing energy receiving power is further arranged in the power receiving coil, and the transmitter comprises a power transmission coil which is arranged correspondingly with the power receiving coil and transmits energy to the power receiving coil.

[0056] When the frequency of the external alternating magnetic field is f Due to LC resonance, a high induced electromotive force can be generated at both ends of the circuit to drive the light emitting element to emit light.

[0057] Wherein, f is the frequency of the external alternating magnetic field; LC is a resonance circuit comprising an inductor and a capacitor connected together; the inductor is the power receiving coil and is denoted by the letter L; and the capacitor is denoted by the letter C.

[0058] In the utility model, in order to meet the clinical scene of preoperative positioning and intraoperative search, the magnetic resonance type electric energy transmission mode is adopted, the characteristic of the magnetic resonance type electric energy transmission is that the frequency of the alternating magnetic field generated by the transmitter is same with the oscillation frequency of the transducing mechanism in the load cavity as the locator, and the advantage is that the transmission distance is larger, the efficiency is higher, and the receiver circuit is simple. The wireless electric energy transmission is carried out in the mode of magnetic field coupling, and the basic physical principle meets the Faraday's law of electromagnetic induction That is, the induced electromotive force is generated due to the change of magnetic flux, so that the current is generated in the receiving coil.

[0059] Wherein, the main function of the transmitter is to generate an alternating magnetic field for realizing wireless energy transmission. The load cavity needs to be conveniently placed and fixed near the lesion, and the transducing mechanism in the load cavity receives the energy of the alternating magnetic field generated by the transmitter, converts the energy into electric energy through electromagnetic induction and makes the light emitting element emit light, so that the positioning function is realized.
