Description
Technical Field
The invention belongs to the technical field of medical devices, relates to a technology for improving the accuracy of an endoscopic exploration result, and in particular relates to a capsule probe ultrasonic endoscope.
Background
Submucosal lesions (submucosal lesions, SMLs) are referred to clinically as raised lesions or bumps covered by intact mucosa. Studies have shown that the incidence of digestive tract submucosal lesions is about 0.4%. SMLs include gastrointestinal stromal tumors (gastrointestinal stromal tumor, GIST), smooth myomas, schwannomas, and ectopic pancreas. Most SMLs are benign and can be closely followed without special treatment, but GIST, regardless of volume size, are considered potential malignant tumors. The early discovery and treatment of the submucosa lesions can effectively inhibit the transformation of the submucosa lesions to malignant tumors.
In recent decades, digestive endoscopy has evolved rapidly, and minimally invasive techniques featuring endoscopic treatment have increasingly important roles in the diagnosis and treatment of early and pre-cancerous lesions of the digestive tract. However, the common endoscope can only observe the mucosal surface of the digestive tract, and the deep structure of the digestive tract lesion cannot be known. The ultrasonic endoscope perfectly combines the common endoscope with the ultrasonic, so that the deep structure of the lesion can be explored while the surface structure of the lesion is observed, the visual field of the endoscope diagnosis is enlarged, and the cognition of the lesion is improved to a three-dimensional level. Small probe ultrasound endoscopy has many advantages over conventional ultrasound endoscopy. The miniature probe is easily introduced through the biopsy channel of the endoscope on the basis of the common endoscope, the pathological change hierarchical origin can be accurately diagnosed under the condition of no interference, the ultrasonic internal image frequency of the small probe is high, the resolution is high, and each layer structure of the wall of the digestive tract can be clearly displayed, so that the infiltration depth of early cancer pathological changes and the distribution of submucosal pathological changes in the digestive tract are clear, the judgment of high accuracy is provided for the pathological change size and the hierarchical origin, and the method has important guiding significance for the selection of a treatment scheme.
Due to the physical properties of ultrasound, a medium is needed during the delivery process, and in order to reduce the interference of gases, the ultrasound endoscopy needs to be filled with water and the gas in the gastrointestinal tract is removed, and the lesion and probe must be operated in water. At present, the ultrasonic gastroscopy method conventionally adopts direct water injection operation, however, some lesions are positioned in the direction opposite to gravity or in a straight cavity, and immediately discharged into a distal digestive tract after water injection, so that water storage is difficult, and the lesions at the upper middle section of the esophagus are easily reversed to the airway to cause aspiration under an anesthetic state by using the direct water injection method, so that the risk of a patient is increased.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 6, the following embodiments of the present invention are provided:
as shown in fig. 1 to 5, a first embodiment of the present invention provides a balloon probe ultrasonic endoscope, which at least includes:
body 1:
wherein one end of the body 1 has a first probe 2;
the first probing unit 2 is configured to obtain at least first target parameter information of a first probing stage;
the target parameter information at least comprises: the position of the lesion, the lesion morphology and the lesion surface characteristics;
a conduction part 3;
after the end of the first probing phase, the conducting part 3 is connected with the end of the body 1;
and, the said conductive part 3 holds a conductive medium at least;
a second probe section 4;
extending into the conducting part 3, and the second probing part 4 sends out a probing signal, wherein the probing signal is conducted to the lesion by the conducting medium;
wherein, the second probing portion 4 is at least configured to acquire second target parameter information of a second probing stage;
the second target parameter information at least comprises: lesion level information, lesion echo information, lesion boundary information, and lesion size information;
wherein the first probing phase is preceded by the second probing phase.
In this embodiment, the front end of the body 1 is equipped with a first probe 2, and the first probe 2 is a medical endoscope, for example, a forward-injection endoscope with model number Olympus GIF-260J can be used. For delivery by the body 1 into a site to be examined of the human body, such as the esophagus or intestine. Whether the part to be inspected has a lesion or not, and parameter information such as the position of the lesion, the morphology of the lesion, surface characteristics and the like are detected by the first probing part 2. When the above information is grasped, it is necessary to withdraw the first probe portion 2 from the human body and assemble the conductive portion 3.
Specifically, the second probe section 4 is an ultrasonic endoscope system, for example, an ultrasonic endoscope system of the model olympus EU-ME2 is adopted, and a 20MH frequency probe is assembled. Since the conduction of ultrasonic waves requires a medium, in the prior art, water is used as a conduction medium, but there are:
the flowing property of water is higher, and it is difficult to stop at pathological change position after intervenes in the human body to flow to other positions, on the one hand causes ultrasonic wave to lack the conduction medium and can't survey, on the other hand can flow back to the air flue and cause the mistake to inhale, increases patient's risk.
Based on this, it is necessary to guide or restrict the flow area of water so that it can contact the lesion site, so that the ultrasonic waves thereby form a conductive path for probing the lesion, and it is also necessary to ensure that the conductive medium can increase the residence time at the lesion site to ensure that the ultrasonic waves obtain a sufficient probing space.
Thus, the present embodiment provides the conductive portion 3 at the front end of the body 1. The conducting part 3 is capable of storing or containing a conducting medium to constrain and restrict the conducting medium, avoiding its disordered flow in the human body and increasing the risk of the patient.
And, on the basis of the above, the conducting part 3 also allows the second probing part 4 to enter, thereby surrounding the probe circumference of the second probing part 4 by a conducting medium, thereby ensuring that the ultrasonic energy has a certain conducting channel.
When the conduction path is formed, it is necessary to communicate the conduction path with the lesion to ensure that ultrasound can be applied to the lesion site for probing. Thus, the present embodiment adopts a form in which the conductive portion 3 is deformed to be in contact with the lesion, so that the second probe portion 4 forms a signal transmission channel with the lesion, thereby collecting at least lesion level information, lesion echo information, lesion boundary information, and lesion size information.
Moreover, the conductive part 3 is contacted in a deformation mode, so that the contact area between the conductive part 3 and the lesion is increased, the conductive medium can be covered on the surface of the lesion to a larger extent, and then the lesion can be comprehensively probed and analyzed by ultrasonic waves, so that the accuracy of a probing result is improved. Furthermore, the flexible contact can be changed along with the information of the lesion, such as the size of the lesion position, the size of the bump height and the size of the surface concave-convex degree, so that the occurrence of a probing dead angle is avoided, and the accuracy of a probing result is further improved. And, the flexible contact of the conduction part 3 can not cause excessive load to the lesion, so as to avoid secondary damage to the lesion.
As shown in fig. 1 to 5, a second embodiment of the present invention proposes a balloon probe ultrasonic endoscope, and on the basis of the first embodiment, the conductive part 3 includes at least:
a wall surface 301;
the walls 301 enclose a chamber 302 for filling the conductive medium;
moreover, the wall 301 is flexible, and the wall 301 can be in flexible contact with lesions.
In this embodiment, when constraining the conductive medium, the following needs to be considered:
firstly, the fluidity of the conductive medium needs to be maintained to ensure that the conductive medium can wrap or cover the lesion, but the flow of the conductive medium needs to be restrained to avoid the condition of disordered flow;
secondly, the contact area between the conductive part 3 and the lesion determines the probing area of the second probing part 4, and the sizes of the lesions are significantly different, so that it is necessary to ensure that the conductive part 3 has a larger contact area when facing lesions of different sizes.
Thus, the wall 301 of the conducting portion 3 is flexible, thereby causing the volume of the chamber 302 it forms to be variable, which can be filled with different volumes of conducting medium to achieve different filling states, thereby adapting to contact with lesions of different sizes. Further, the wall 301 is in flexible contact with the lesion to ensure:
first, the wall 301 can be deformed to increase or decrease the contact area with the lesion, so as to form a package or cover for lesions of different sizes.
Secondly, the degree of adhesion of the wall 301 and the lesion is improved, so that the breakpoint area between the wall 301 and the lesion is reduced, namely, the non-contact area is reduced, and accordingly, ultrasonic waves can be comprehensively involved in the lesion exploration, and the exploration efficiency and the effect are improved.
In a specific embodiment, the conductive portion 3 is made of medical rubber, which may be a rubber sleeve.
As shown in fig. 5, a third embodiment of the present invention proposes a balloon probe ultrasonic endoscope, and on the basis of the above embodiment, the conductive part 3 further includes:
a connection port 303;
the connection port 303 constitutes a removable connection at a distance L1 from the end of the body 1;
wherein, the value range of L1 is: 5 to 15mm.
In the present embodiment, the conductive part 3 further has a connection port 303.
Since the balloon probe ultrasonic endoscope provided in the present embodiment has the first probing stage and the second probing stage, and the probing principles of the two probing stages are different, the conductive portion 3 is only required to be mounted to the body 1 before the second probing stage starts, so as to ensure smooth conduction of the ultrasonic signal.
Based on this, the transmission portion is formed with a connection port 303. And, the connection port 303 forms a detachable connection with the body 1 to be detached in a first probing stage and to be mounted in a second probing stage.
If the connection position of the connection port 303 is too long, the length of the circumferential wall surface of the plate body end portion, which is wrapped by a part of conductive medium, is increased, so that part of energy is wasted in the transmission of the ultrasonic wave, that is, part of ineffective detection is formed, and the accuracy of the detection result is reduced.
If the connection position of the connection port 303 is too short, the connection surface between the conductive portion 3 and the body 1 is reduced, so that the stable connection state of the chamber 302 after the filling process cannot be ensured, and even the conductive portion 3 falls off.
Based on this, the connection position of the connection port 303 is defined with the aforementioned parameters to ensure avoidance of ineffective flow of the conductive medium and avoidance of endless waste of ultrasonic energy, and to ensure stable connection of the transmission portion in the filled state.
As shown in fig. 1 to 5, a fourth embodiment of the present invention provides a balloon probe ultrasonic endoscope, and further includes, based on the previous embodiment:
an air injection part 5 connected to one end of the body 1;
wherein the gas injection part 5 is provided with a gas injection port, and the gas injection port is positioned at one side of the first probing part 2;
wherein the diameter of the end part of the body 1 is D1, and the diameter of the gas injection port is D2;
d1=k1×d2;
the value range of D1 is: 2 to 4mm;
the value range of K1 is: 3 to 5.
In this embodiment, the site to be inspected is normally in a closed state during the probing process, so that the lesion cannot be completely exposed within the probing range.
Based on this, add the gas injection portion 5, the gas injection mouth of gas injection portion 5 sets up in one side of first investigation portion 2 to in the investigation in-process, carry gas through air pump and gas injection pipeline, so that wait to examine the position and be in opening and shutting, and then ensure that the disease changes can expose in the investigation scope completely.
In addition to the above, the diameter of the gas injection port is defined.
The reason is that, since the body 1 is inserted into the inside of the human body, if the diameter thereof is too large, it may be difficult to insert into the human body or scratch the portion to be inspected. Further, the addition of the gas injection portion 5 further increases the radial dimension of the front end of the body 1, which causes the aforementioned problems.
However, if the diameter of the gas injection port is small, the gas entry amount is reduced, so that the part to be inspected cannot be completely opened, and therefore dead angles exist in the probing range, and errors of the probing result are caused.
Based on this, the diameter of the end of the body 1 and the need for the gas injection port satisfy the aforementioned parameter definitions to ensure that the delivery content of the gas is increased to ensure that the site to be inspected is fully opened and that the lesion site is fully exposed, while ensuring that the body 1 is not subjected to excessive resistance.
As shown in fig. 6 to 8, a fifth embodiment of the present invention proposes a balloon probe ultrasonic endoscope, and based on the above embodiment, the end portion of the body 1 has:
a first connection structure 601 and a second connection structure 602;
the diameter of the first connection structure 601 is D3, and the range of values of d3=d1-K2, K2 is: 1 to 2.5mm;
the diameter of the second connection structure 602 is D4, and d4=d2;
and, the connection structure 601 is configured to allow the connection port 303 to form a detachable connection with the body 1;
the second connection structure 602 is configured to allow the gas injection part 5 to be detachably connected to the body 1.
In the present embodiment, since the connection port 303 of the conduction portion 3 and the gas injection portion 5 need to be connected to the body 1, binding is performed by a medical rubber ring, for example. Thereby increasing the radial dimension of the connecting position and further causing the problems of scratch and the like of the part to be inspected.
Therefore, a first connection structure 601 and a second connection structure 602 are added to the body 1.
The diameter of the first connecting structure 601 meets the above parameter requirement, so that the first connecting structure 601 contracts along the radial direction of the body 1 to form an installation space for accommodating the connection structure of the conductive part 3 and the body 1, and further radial expansion of the position is avoided.
Similarly, the diameter of the second connection structure 602 meets the above-mentioned parameter requirements, so that the second connection structure 602 is contracted along the radial direction of the body 1 to form an installation space for accommodating the connection structure of the gas injection part 5 and the body 1.
As shown in fig. 6 to 8, a sixth embodiment of the present invention provides a balloon probe ultrasonic endoscope, and based on the above embodiment, the first connection structure 601 is a first sink formed along a circumferential wall surface of the body 1, the second connection structure 602 is a second sink formed along an axial direction of the body 1, and further comprising:
and the covering part 7 is at least provided with a flexible surface, and the flexible surface covers the first sink groove and the second sink groove.
In the present embodiment, the specific structures of the first connection structure 601 and the second connection structure 602 are defined.
The first connection structure 601 is a sink groove which is contracted inwards along the circumferential wall surface of the body 1, and has a ring groove structure for connecting the conductive part 3.
On the basis of the above, it is considered that the inside of the conductive part 3 is filled with a conductive medium such as water, and therefore, it is necessary to secure the sealing property of this connection position to avoid the occurrence of leakage of the conductive medium.
Thus, a sealing structure, such as a medical rubber ring, can be added to the connection structure 601 to further improve the connectivity and tightness of the transmission and connection structure 601.
The second connection structure 602 is a second countersink formed along the axial direction of the body 1, and is used for accommodating the installation of the gas injection pipe and the gas injection port of the gas injection part 5, so as to avoid the problem of increasing the diameter size of the body 1.
Correspondingly, the sealing part can be added to ensure the stable connection of the gas injection pipeline and the gas injection port in the second sinking groove.
On the basis of the above, a covering part 7 is further added, and the covering part 7 is formed with a flexible surface for covering the connection trace in a covering manner after the connection port 303 and the gas injection part 5 are assembled, so as to avoid the problem that the connection trace scratches the part to be inspected.
As shown in fig. 6 to 8, a seventh embodiment of the present invention provides a balloon probe ultrasonic endoscope, and further includes, based on the previous embodiment:
a beam section 8 provided at an end of the main body 1;
wherein, the beam part 8 is communicated with the gas injection part 5;
and, the beam portion 8 forms a beam passage at least along the circumferential wall of the body 1, and the beam passage has a plurality of beam holes 801;
the gas of the gas injection part 5 is output from the beam hole 801, and forms a gas film on the wall 301.
In the present embodiment, when the gas injection portion 5 performs gas injection, there are the following problems:
firstly, because the gas injection port is positioned at one side of the front end of the body 1, the gas injection area is relatively deviated, and the part to be inspected is supported by weaker gas at the opposite side of the gas injection area, so that the situation that the folds of the area cannot be unfolded occurs, and dead angles of a probing range are formed;
secondly, when the gas is injected, the deformation area of the transmission part is uneven due to the action force of the gas on one side of the transmission part 3, so that the transmission part 3 is easy to break, and a large amount of transmission medium flows out. And the centralized single-side gas delivery can cause relatively larger acting force on the wall surface 301 at the position of the conducting part 3, so that when the wall surface 301 at the position is contacted with a lesion, flexible contact with relatively higher bonding degree cannot be formed, and further, the accuracy of a probing result is reduced.
Thus, the beam portion 8 is increased. The beam portion 8 may be an annular beam ring, and has a hollow configuration inside to form a beam passage, and a plurality of beam holes 801 are formed along a circumferential wall surface of the beam ring for the transportation of gas.
It can be seen that the beam portion 8 can restrict and guide the output path of the gas so as to avoid the concentrated output of the gas from a single side, thereby ensuring that the gas can be conveyed to the portion to be inspected in a uniform manner and ensuring the complete opening of the portion to be inspected. In addition, the gas can form a gas film along the circumferential wall surface of the conductive part 3, and the gas film can provide a relatively uniform restraining force on the wall surface 301 of the conductive part 3, so as to avoid the problem that the conductive part 3 is excessively filled to rupture in a human body.
An eighth embodiment of the present invention provides a balloon probe ultrasound endoscope, and based on the previous embodiment, the ultrasound endoscope further includes a third connection structure 9, the diameter of the third connection structure 9 is D5, and the range of values of d5=d1-K3, K3 is: 1 to 2.5mm.
In the present embodiment, the third connection structure 9 is used for mounting the beam portion 8, and the beam portion 8 is prevented from causing an increase in the radial dimension of the body 1.
A ninth embodiment of the present invention provides a balloon probe ultrasonic endoscope, and on the basis of the above embodiment, the beam portion 8 at least forms:
a constraint structure 10, the constraint structure 10 being formed along a circumferential wall surface of the beam portion 8;
and, the constraint structure 10 is configured to provide at least a flexible constraint force to the wall 301 away from the front end of the body 1.
In the present embodiment, the beam portion 8 is also formed with a constraint structure 10.
In which the rear end of the conductive part 3 is less likely to contact the lesion to serve as a transmission channel, the conductive medium should be prevented from collecting in the region to avoid endless waste. Therefore, the restraint structure 10 can exert a flexible restraint force on the avoidance of the conductive portion 3 away from the front end of the body 1, so that the conductive medium can be more concentrated at the front end of the conductive body, thereby improving the conductive efficiency and conductive quality of the ultrasonic wave. The restraining structure 10 may be a ring-shaped elastic body protruding a certain distance along the axial direction, and the diameter of the ring-shaped elastic body is not too large, so as to avoid scratching the part to be inspected.
A tenth embodiment of the present invention provides a balloon probe ultrasonic endoscope, and on the basis of the above embodiment, the body 1 at least includes:
a working end 101, wherein the first probe portion 2 is disposed at the working end 101;
an intervention circuit 102 in communication with said working end 101;
wherein the interventional line 102 forms at least:
a first channel and a second channel;
and, the first channel is configured for intervention by the conductive medium;
and, the second channel is configured as an intervention of the second probe 4.
In the present embodiment, the body 1 is constituted by a working end 101 and an intervention tube 102.
Wherein for the conductive medium the transport can take place through the first channel and for the intervention of the second probe 4 the transport can take place through the second channel.
