Description

Technical Field

[0001] This application relates to the field of clinical medical auxiliary instruments, and particularly to an optoelectronic probe for cervical cancer screening instruments. Background Art

[0002] Cervical cancer is a relatively common gynecological malignant tumor. In recent years, the widespread application of cervical cytology screening has enabled the timely detection and treatment of cervical cancer lesions, reducing its incidence and mortality.

[0003] The optoelectronic detection method is one of the mainstream means for screening cervical lesions. By combining an optoelectronic probe with colposcopy, the visibility of cervical tissue is enhanced through light and image processing technologies, helping doctors accurately observe the changes in cervical epithelium and blood vessels, thereby detecting suspicious lesion sites.

[0004] The external structure of the optoelectronic probe is relatively simple, including a handle part and a probe part that are plugged together. The two parts transmit signals through the connection of electrodes and optical fibers. Among them, the handle part is a disposable consumable. During cervical cancer screening, a clinician takes a new probe part and plugs it into the handle part. After the screening process is over, the clinician disassembles and discards the probe part from the handle part.

[0005] Under the existing technology, the structural form of the optoelectronic probe is mostly an electrode spring needle structure. When the probe part is plugged into the handle part, the electrode spring needles of the handle part are prone to deflection and cannot be plugged into the jacks of the probe part in a single attempt. Therefore, the spring needles are prone to bending and deformation problems during multiple pluggings and unpluggings, damaging the handle part of the optoelectronic probe. Summary of the Invention

[0006] In order to improve the service life of the handle part in the optoelectronic probe and facilitate the clinical use of the optoelectronic probe, this application provides an optoelectronic probe for a cervical cancer screening instrument.

[0007] The optoelectronic probe for a cervical cancer screening instrument provided by this application adopts the following technical solutions:

[0008] An optoelectronic probe for a cervical cancer screening instrument includes a handle base and a probe base. One end of the probe base is plugged into one end of the handle base, and further includes;

[0009] A probe head is provided at one end of the probe base for information collection, and an optical fiber for transmitting the information collected by the probe head is provided in the handle base;

[0010] Electrode spring needles are provided at one end of the handle base where the probe head is plugged;

[0011] A contact plate is provided in the probe base. As the probe base is plugged into the handle base, the contact plate abuts against the end of the electrode spring needle;

[0012] A jack is provided at one end of the probe holder that is inserted into the handle holder corresponding to the electrode spring pin, and the aperture diameter is larger than the diameter of the electrode spring pin.

[0013] By adopting the above technical solution, the handle holder is the main body of the handle part, and the probe holder is the main body of the probe part. When the handle holder is inserted into the probe holder, the electrode spring pin on the handle holder passes through the jack and contacts the contact plate. In the above solution, the way of pressing the electrode spring pin against the contact plane is adopted to replace the electrode spring pin structure in the traditional solution. The electrode spring pin penetrates through the jack with a larger aperture diameter, and the end of the electrode spring pin abuts against the contact plate to realize electrode conduction, and power supply is realized inside the photoelectric probe. When performing clinical screening, the clinician inserts the probe head into the patient's cervix to collect tissue information, and the information is transmitted through the internal optical fiber.

[0014] Optionally, it further includes;

[0015] A clamping component is arranged at the insertion end of the probe holder and the handle holder, and the clamping component is used to strengthen the insertion of the probe holder and the handle holder.

[0016] By adopting the above technical solution, since the above solution uses a larger jack, if the electrode spring pin is not strengthened, the electrode spring pin is in a free state in the jack, which easily leads to unstable current inside the photoelectric probe. Therefore, the clamping component is necessary.

[0017] Optionally, it further includes;

[0018] An adapter, which is a part of the probe holder body, is used to install the probe head, and an adapter component for fixing the probe head is arranged on the adapter.

[0019] By adopting the above technical solution, considering the issues of health and hygiene, the probe part, especially the probe head and the parts close to the probe head that need to enter the patient's body, cannot be reused, and the contact plate arranged in the probe holder cannot be used as a disposable consumable. Therefore, in the above solution, an adapter is provided, and the probe head is fixed through the adapter component on the adapter. Thus, when the cervical cancer screening of a single patient is completed, the clinician can disassemble the probe head and replace it with a new one.

[0020] Optionally, it further includes;

[0021] A probe tube is arranged at one end of the probe holder, connecting the adapter and the probe head, and the end face diameter of the probe tube is smaller than the end face diameter of the probe holder.

[0022] By adopting the above technical solution, the end face diameter of the probe tube is smaller than the end face diameter of the probe holder, and it is relatively slender. One end of the probe tube is connected to the probe head, and the other end is connected to the adapter component and fixed on the adapter, which is convenient for the clinician to control the probe head.

[0023] Optionally, it further includes;

[0024] A probe rod housing is provided at one end of the adapter near the probe rod head. An inner cavity is formed in the probe rod housing. One end of the probe rod tube near the adapter is inserted into the probe rod housing. The inner cavity diameter of the probe rod housing near the probe rod head is smaller than that of the other end of the probe rod housing.

[0025] By adopting the above technical solution, one end of the probe rod housing is fixed to the adapter. The inner cavity of the probe rod housing serves as a protective shell for the connection part between the probe rod tube and the adapter. A part of the probe rod housing near the probe rod head has a smaller diameter than the other end of the probe rod housing and is adapted to the probe rod tube, which plays a constraining role on the probe rod tube and strengthens the fixation of the probe rod tube.

[0026] Optionally, it further includes;

[0027] A soft protective cover is provided at one end of the handle seat where it is inserted into the probe seat. The soft protective cover is made of a soft material. As the handle seat and the probe seat are disassembled, the soft protective cover bends and fits the end of the handle seat.

[0028] By adopting the above technical solution, the soft protective cover is used to protect one end of the handle seat inserted into the probe seat. After a single cervical cancer screening is completed, or when the handle seat is in a sealed state, the soft protective cover should be covered on the probe seat to protect the electrode spring needle structure inside the handle seat.

[0029] Optionally, a protective cavity is formed at one end of the handle seat where it is inserted into the probe seat;

[0030] The protective cavity is used to protect the electrode spring needle.

[0031] By adopting the above technical solution, the electrode spring needle is arranged in the inner cavity at one end of the handle seat where it is inserted into the probe seat. When the handle seat is inserted into the probe seat, one end of the probe seat near the probe seat is inserted into the inner cavity until the end of the electrode spring needle touches the contact plate. Thus, the connection between the probe seat and the handle seat can be restricted by the constraint of the inner wall structure of the inner cavity of the handle seat.

[0032] Optionally, it further includes;

[0033] A converging block is provided inside one end of the handle seat where it is inserted into the probe seat. A perforation for the optical fiber to pass through is formed in the central part of the converging block.

[0034] By adopting the above technical solution, the converging block is arranged inside the handle base. The perforation in its central part is used to provide a channel for the optical fiber to pass through. The optical fiber end inside the handle base is inserted into the perforation in the central part of the converging block and fixed. When the handle base is inserted into the probe base, while the electrode of the handle base abuts against the contact plate of the probe base, the optical fiber inside the probe base is docked with the optical fiber inside the handle base to build a transmission channel for information.

[0042] The following will further describe the present application in detail Figure 1-6 in conjunction with the appended

[0043] An optoelectronic probe for a cervical cancer screening instrument is disclosed in an embodiment of the present application. Referring to Figure 1 , an optoelectronic probe for a cervical cancer screening instrument is composed of two parts, namely a handle part 2 and a probe part 1. The handle part 2 and the probe part 1 can be combined into an integral whole. Among them, the probe part 1 is used to penetrate into the cervical part of the patient to collect information, and the handle part 2 is connected to a display terminal to transmit the information collected by the probe part 1 to the display terminal for real-time display for direct observation by clinical physicians.

[0044] In actual clinical applications, clinicians need to change different photoelectric probes for patients of different age groups and different cervical conditions. Therefore, in this embodiment, the handle part 2 is separated from the probe part 1, and the same handle part 2 can be used to meet the needs of plugging in any type of probe part 1.

[0045] Probe part 1:

[0046] Reference Figure 2 and Figure 3 The probe part 1 includes a probe seat 11 as a main structure and an adapter 12 fixedly connected to one end of the probe seat 11, and the end of the probe seat 11 away from the adapter 12 is used for plugging with the handle part 2, which is a plug-in end; the central part of the adapter 12 away from the probe seat 11 is formed with a plug-in structure, and a probe tube 13 is plugged in, and the end of the probe tube 13 away from the probe seat 11 is fixedly connected to a probe head 14; in this embodiment, a photoelectric probe is arranged inside the probe head 14, and an optical fiber for information transmission is arranged inside the probe tube 13, which serves as a transmission channel for the probe head 14 to collect information; when screening patients for cervical cancer, the clinician selects a probe seat 11 of the corresponding model, unpacks the new probe tube 13 and the probe head 14, sets the probe tube 13 and the probe head 14 on the optical fiber, and then plugs one end of the probe tube 13 into the adapter 12 to complete the installation.

[0047] Reference Figure 2 and Figure 4 The plug-in structure in this embodiment is a rod-shaped structure adapted to the probe tube 13 formed in the center of the adapter 12. Therefore, the clinician can directly plug the probe tube 13. In order to stabilize the plug-in structure of the probe tube 13, the adapter 12 is used to plug the probe tube 13. The end face edge is clamped with a probe housing 15. The probe housing 15 has an inner cavity and openings at both ends. The two ends of the probe housing 15 have different diameters. One end diameter is adapted to the end face diameter of the probe tube 13, and the other end is directly The diameter is equal to the end face diameter of the adapter 12 and is installed on the adapter 12; in this embodiment, the end with the larger diameter of the probe rod housing 15 is installed on the adapter 12. During the above-mentioned insertion process of the probe rod tube 13, the doctor needs to pre-install the probe rod housing 15, and then insert the end of the probe rod tube 13 away from the probe rod head 14 into the smaller diameter end of the probe rod housing 15. Therefore, when the probe rod tube 13 is inserted into the adapter 12, the smaller diameter end of the probe rod housing 15 can play a role in reinforcing the connection of the probe rod tube 13.

[0048] Reference Figure 3 The adapter 12 is provided with an annular locking tooth 121 at an end surface edge close to the adapter rod, which is used to clamp the above-mentioned probe tube 13.

[0049] Reference Figure 2The end face diameter of the plug-in end of the probe seat 11 is smaller than the end face diameter of the other end of the probe seat 11, so that the plug-in end of the probe seat 11 is stepped, which is convenient for plugging with the handle part 2. The plug-in end of the probe seat 11 is provided with a clamping structure for fixing the connection between the handle part 2 and the probe seat 11. In this embodiment, the clamping structure includes a plurality of clamping strips 111 formed on the side wall of the plug-in end of the probe seat 11; considering the circumferential positioning of the probe seat 11 and the handle part 2 after plugging, the clamping assembly also includes a clamping block 112 formed on the side wall of the probe seat 11, and the length direction of the clamping block 112 is parallel to the axial direction of the probe seat 11. Therefore, in this embodiment, the connection between the probe seat 11 and the handle part 2 is reinforced by the clamping strip 111, and the circumferential positioning of the two parts after the connection is performed by the clamping block 112.

[0050] Handle part 2:

[0051] Reference Figure 5 and Figure 6 The handle portion 2 includes a handle seat 21 as a main structure, one end of the handle seat 21 is a plug-in end for plugging into the probe seat 11. During cervical cancer screening, the clinician plugs the plug-in end of the handle seat 21 into the plug-in end of the probe seat 11; when the handle seat 21 is plugged into the probe seat 11, a composite cable 26 is fixedly connected to the end of the handle seat 21 that is away from the probe seat 11. In this embodiment, the composite cable 26 is composed of an optical fiber and an electrode wire, which can provide a power supply channel and an optical fiber information transmission channel for the photoelectric probe. An inner cavity for accommodating the optical fiber and the electrode wire is provided inside the handle seat 21. When the handle seat 21 is plugged into the probe seat 11, the composite cable 26 connects the photoelectric probe and the display terminal, and transmits the information collected by the probe head 14 to the display terminal.

[0052] Reference Figure 5 and Figure 6 The side wall of the plug-in end of the handle seat 21 extends in a direction away from the center of the handle seat 21 to form a protective cavity 25 of a cylindrical structure. The size of the cavity opening of the protective cavity 25 is adapted to the size of the plug-in end of the probe rod seat 11. When the handle seat 21 is plugged into the probe rod seat 11, the stepped structure of the plug-in end of the probe rod seat 11 is plugged into the protective cavity 25, and relies on the fixation of the clamping strip 111 on the probe rod seat 11 to complete the stable connection between the handle seat 21 and the probe rod seat 11; a clamping groove is provided on the side wall of the protective cavity 25 corresponding to the clamping block 112 of the probe rod seat 11. When the handle seat 21 is plugged into the probe rod seat 11, the clamping block 112 is plugged into the clamping groove to prevent the handle seat 21 from unstable rotation after plugging.

[0053] Reference Figure 5, in order to protect the internal structure of the protection cavity 25 at the handle end, a soft protective cover 22 is provided on the handle base 21. The size of the soft protective cover 22 is adapted to the size of the orifice of the protection cavity 25 at the handle end, so that the soft protective cover 22 can be directly buckled on the orifice of the protection cavity 25 at the handle end to achieve a sealing effect; soft strips are formed on the soft protective cover 22, and the soft strips are fixedly connected to the handle base 21 to ensure the connection between the soft protective cover 22 and the handle end. After the screening work is completed, the clinical physician buckles the soft protective cover 22 on the orifice of the protection cavity 25 at the handle end.

[0054] Connection between the handle part 2 and the probe part 1:

[0055] Refer to Figure 2 And Figure 4 , since the optoelectronic probe needs to be inserted in two parts, it is necessary to consider whether a complete optical signal transmission channel can be built and the integrity of information transmission after insertion; in this embodiment, a contact plate 16 is provided inside the probe base 11. The contact plate 16 is an annular plate, the contact plate 16 is coaxially arranged with the probe base 11, the contact plate 16 is connected to the electrode wire inside the probe base 11, and a plurality of jacks 113 communicating with the inside of the probe base 11 are opened on the end face of the insertion end of the probe base 11. The plurality of jacks 113 are distributed on the same circumferential line and are opened corresponding to the annular surface of the contact plate 16. The opening direction of the jacks 113 is parallel to the axial direction of the probe base 11.

[0056] Refer to Figure 5 And Figure 6 , a plurality of electrode spring needles 23 are provided in the protection cavity 25 of the handle base 21 corresponding to the jacks 113. The cross-sectional diameter of the electrode spring needles 23 is smaller than the aperture of the jacks 113. The electrode spring needles 23 are connected to the electrode wires inside the optoelectronic probe. With the insertion of the handle base 21 and the probe base 11, the electrode spring needles 23 are inserted into the jacks 113, and the ends of the electrode spring needles 23 abut against the contact plate 16, realizing the contact between the spring needles and the contact plane, achieving the effect of easy alignment during insertion and removal, thereby improving the service life of the handle during insertion and removal.

[0057] Refer to Figure 4 And Figure 6 , a fiber optic hole is opened in the center part of the end face of the insertion end of the probe base 11, and the optical fiber in the probe tube 13 extends out of the fiber optic hole. A fiber optic connector is installed on the part of the optical fiber extending out of the fiber optic hole.

[0058] Refer to Figure 5 And Figure 6, a beam collecting block 24 is fixedly connected inside the insertion end of the handle base 21. One end face of the beam collecting block 24 close to the insertion end serves as the bottom wall of the protection cavity 25, and the above-mentioned electrode spring needle 23 is inserted on the beam collecting block 24; a through hole 241 for optical fiber penetration is provided in the middle of the beam collecting block 24, and the optical fiber is inserted into the through hole 241. An optical fiber connector is installed at one end of the optical fiber close to the through hole 241. When the probe base 11 is inserted into the handle base 21, the optical fiber connector in the probe base 11 is docked with the optical fiber connector in the handle base 21; the optical fiber connector and the optical fiber are prior arts and will not be elaborated in this embodiment.

[0059] The implementation principle of the optoelectronic probe of the cervical cancer screening instrument in the embodiment of the present application is as follows: Before clinical screening, a clinician needs to select the model of the probe base 11 corresponding to the patient, unseal a new probe tube 13 and a probe head 14, put the probe tube 13 and the probe head 14 on the optical fiber, and insert one end of the probe tube 13 into the inside of the probe housing 15 and install it on the adapter 12.

[0060] The clinician then inserts the insertion end of the handle base 21 corresponding to the insertion end of the probe base 11 to complete the connection between the handle base 21 and the probe base 11.

[0061] After the end of a single cervical cancer screening process, the clinician removes the probe tube 13 and the probe head 14 from the adapter 12, then disassembles the probe base 11 and the handle base 21, and closes the soft protective cover 22.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
