Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular to a proctoscope system with night vision capability. Background Technology
[0002] In clinical practice, examinations in the proctology department and surgeries in the anus and rectum often require the assistance of auxiliary instruments such as anoscopes and anal dilators. The role of the anoscope is to open the anus in preparation for subsequent examinations and treatments.
[0003] Commonly used anorectal endoscopes include an outer sleeve, an endoscope, and a display screen electrically connected to the endoscope. The outer sleeve is duckbill-shaped, and the endoscope is inserted into the outer sleeve. The endoscope has an LED cold light source at its tip. When performing anorectal surgery or examination on a patient, medical staff need to apply lubricant to the outer sleeve and insert it into the patient's anus to perform anal dilation. Then, the endoscope is inserted into the outer sleeve to perform the colonoscopy and subsequent treatment.
[0004] Regarding the aforementioned techniques, because the outer sleeve is duckbill-shaped, after it is inserted into the patient's anus for dilation, the body's sphincter muscles will involuntarily and regularly contract, making it easy to expel or suck the outer sleeve out. Therefore, the outer sleeve is often fixed with a handle. When medical staff perform proctoscopy, they need to hold the handle with one hand to fix the position of the outer sleeve, operate the endoscope with the other hand, and keep their eyes on the display screen. Medical staff need to multitask, making the operation quite cumbersome. Utility Model Content
[0005] To simplify the process of securing the outer sleeve for medical staff, thereby allowing them to focus on operating the endoscope, this application provides a proctoscope system with night vision capability.
[0006] The proctoscope system with night vision function provided in this application adopts the following technical solution:
[0007] A proctoscope system with night vision capability includes an outer sleeve, an endoscope, and a display device electrically connected to the endoscope. A handle is fixedly connected to the outer sleeve, and a fixing component is also provided on the handle. The fixing component includes a fixing ring located on the side of the handle away from the outer sleeve. The fixing ring includes two mutually movable abutting blocks that move closer to or further away from each other. The two abutting blocks form a ring, and the fixing ring is used to fix it to a hospital bed.
[0008] By adopting the above technical solution, when a patient undergoes anorectal endoscopy or surgery, medical staff first apply lubricant to the outer sleeve and then insert the outer sleeve into the patient's anus. Then, by adjusting the clamping blocks, the medical staff clamp and fix the two clamping blocks to the bed rails, thus fixing the fixing ring to the bed. This makes the outer sleeve stably positioned inside the patient's anus, eliminating the need for medical staff to hold it at all times. This allows medical staff to concentrate on operating the endoscope by referring to the display screen.
[0009] Optionally, the fixing component further includes a connecting strip disposed on the end side of the grip, the connecting strip being disposed between the grip and the fixing ring, and the connecting strip being a bamboo tube that can be bent at any angle.
[0010] By adopting the above technical solution, the position where the outer sleeve needs to be fixed varies depending on the patient's body shape. The bamboo tube connects the fixing ring and the outer sleeve, which facilitates proctoscopy-related examinations and surgeries for people of different body shapes. The bamboo tube is easy to adjust and fix, reducing the related operations for medical staff.
[0011] Optionally, the two abutment blocks are provided with adjustment handles on their adjacent ends, and an elastic element is provided between the two adjustment handles to drive the two abutment blocks to always remain close together.
[0012] By adopting the above technical solution, when medical staff need to fix the fixing ring to the hospital bed, the medical staff squeeze the adjustment handle to compress the elastic element, thereby separating the two clamping blocks until the bed railing or edge is between the two clamping blocks. At this time, the medical staff release the adjustment handle, and under the action of the elastic element's restoring force, the two clamping blocks are clamped together, thus achieving the clamping and fixing of the fixing ring to the hospital bed.
[0013] Optionally, the connecting strip is detachably connected to the grip.
[0014] By adopting the above technical solution, the connecting strip and the handle are designed to be detachably connected. During some simple anorectal examinations, medical staff do not need to fix the outer sleeve to the bed. They can directly hold the handle and perform anorectal examinations by digital rectal examination. The operation is simple and expands the applicability of the outer sleeve. At the same time, when using disposable outer sleeves, medical staff can detach the outer sleeve from the connecting strip to replace and discard the disposable outer sleeve, realizing the sustainable use of the connecting strip and the fixing ring and saving resources.
[0015] Optionally, the handle is provided with a clamping block at one end, the connecting strip is provided with a clamping block at one end, and multiple sets of clamping blocks are provided, and multiple clamping blocks surround a clamping cavity for clamping the clamping block. The outer peripheral wall of the clamping block is inclined, and multiple clamping blocks are threaded with adjusting sleeves on their outer peripheral sides.
[0016] By adopting the above technical solution, when medical staff need to disassemble the connecting strip and the handle, they can loosen the adjusting sleeve to separate the multiple clamping blocks from each other, thereby separating the clamping blocks from the locking blocks. At this time, the outer sleeve can be replaced individually. When the outer sleeve needs to be fixed, medical staff insert the locking block on the handle into the clamping cavity formed by the multiple clamping blocks, and then rotate the adjusting sleeve to clamp the locking block with the multiple clamping blocks, thereby connecting the connecting strip and the handle.
[0017] Optionally, the outer sleeve is a transparent sleeve, and a first light guide tube is embedded in the inner wall of the outer sleeve, and a first light supply element is provided at the grip to supply light to the first light guide tube.
[0018] By adopting the above technical solution, the outer sleeve is made transparent. When performing anorectal endoscopy on a patient, the first light supply component supplies light into the first light guide tube, which facilitates the illumination of the patient during routine anorectal examinations by medical staff. The light source is placed at the handle to reduce the impact of the light source on the internal organs of the human body.
[0019] Optionally, the endoscope is provided with a second light guide tube, and the operating end of the endoscope is provided with a second light supply element for supplying light to the second light guide tube.
[0020] By adopting the above technical solution, a second light guide tube is set inside the endoscope. When performing anorectal examinations or surgeries on patients, the second light supply component supplies light into the second light guide tube, which facilitates subsequent examinations by medical staff. At the same time, it reduces the impact of the light source on internal organs when the light source is placed on the endoscope side, and does not affect subsequent observation of anorectal tissues by medical staff through the endoscope.
[0021] Optionally, both the first light source and the second light source are LED cold light sources.
[0022] By adopting the above technical solution, both the first light supply element and the second light supply element are set as LED cold light sources, which further reduces the heat emitted by the first light guide tube and the second light guide tube, and reduces the impact on human tissues.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The outer sleeve is fixed to the hospital bed by a fixing ring set at the handle, so that the outer sleeve is stably positioned at the patient's anus, reducing the change in position of the outer sleeve caused by the contraction of human muscles. At the same time, medical staff do not need to hold it at all times, thus reducing the workload of medical staff.
[0025] 2. The connecting strips allow medical staff to easily fix the position of the outer sleeve according to the different body shapes of patients, thereby improving the adaptability and applicability of the outer sleeve;
[0026] 3. By making the connecting strip and handle detachable, it is easy for medical staff to replace the outer sleeve, and the connecting strip can be reused continuously, saving resources. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] like Figure 1 As shown, patients undergoing proctoscopy often use a dedicated laboratory bed 12. Bed 12 typically has a guardrail on one side, which can be either flip-up or fixed. Bed 12 may also be without a guardrail, but the design of this application is not limited to this. That is, whether or not bed 12 has a guardrail does not limit the feasibility of the design of this application. To facilitate the demonstration of some structures of this application, this application... Figure 1 The bed shown is a fixed-rail hospital bed 12.
[0034] This application discloses a proctoscope system with night vision capability. (Refer to...) Figure 1 and Figure 2A proctoscope system with night vision capability includes an outer sleeve 1, an endoscope 2 that is movably inserted into the outer sleeve 1, and a display device 3 electrically connected to the endoscope 2. The display device 3 is movable. The outer sleeve 1 is cone-shaped, and the diameter of one end of the outer sleeve 1 that is movably inserted into the patient's anus is smaller than the diameter of the other end. A handle 11 is fixedly formed on the side wall of the outer sleeve 1. The handle 11 is arranged perpendicular to the diameter of the outer sleeve 1, and a fixing component 4 is provided at the handle 11. During proctoscopy or examination, medical staff first apply lubricant to the outer sleeve 1, then insert the outer sleeve 1 into the patient's anus. The fixing component 4 ensures that the outer sleeve 1 is always located inside the patient's anus, so that the outer sleeve 1 is not easily displaced due to the body's own muscle contraction / expansion, thus affecting the examination or surgery.
[0035] Reference Figure 2 and Figure 3 The fixing component 4 includes a connecting strip 42 located at the end of the handle 11 away from the outer sleeve 1 and a fixing ring 41 located at the end of the connecting strip 42 away from the handle 11. The fixing ring 41 includes two rotatably connected abutting blocks 411, which together form an abutting cavity. The pivot of the two abutting blocks 411 is provided with an elastic element 44 for keeping the two abutting blocks 411 always abutting. In this application, the elastic element 44 is a torsion spring. An adjustment handle 43 is fixedly connected to one end of the rotatably connected two abutting blocks 411.
[0036] Meanwhile, in this application, the connecting strip 42 is a universal bamboo tube, or it can be a stainless steel corrugated tube. The connecting strip 42 can rotate at any angle. Therefore, when medical staff need to fix the position of the outer sleeve 1, they only need to squeeze the adjusting handle 43 to separate the two clamping blocks 411, then insert the guardrail into the clamping cavity, and then release the clamping block 411. The clamping block 411 clamps the guardrail under the elastic restoring force of the elastic element 44. When the bed 12 does not have a guardrail, the edge of the bed 12 only needs to be inserted into the clamping cavity to clamp the edge of the bed with the fixing ring 41. The position of the outer sleeve 1 and the bed 12 can also be fixed in the same way.
[0037] Reference Figure 3 For hygiene reasons, some outer sleeves 1 are disposable. If the connecting strip 42 or the fixing ring 41 is replaced as a whole when replacing the outer sleeve 1, it will easily lead to waste of resources. Therefore, in order to save resources, the connecting strip 42 is detachably connected to the handle 11. The end of the handle 11 away from the outer sleeve 1 is provided with a clamping block 5, and the end of the connecting strip 42 near the handle 11 is provided with a clamping block 51. There are multiple sets of clamping blocks 51, and the multiple sets of clamping blocks 51 are arranged at intervals along the circumference. The multiple sets of clamping blocks 51 surround the clamping cavity 52 for clamping the clamping block 5, and a gap is left between two adjacent clamping blocks 51.
[0038] The outer wall of the clamping block 51 is inclined, and the thickness of the end of the clamping block 51 near the handle 11 is less than the thickness of the end of the clamping block 51 away from the handle 11. The connecting strip 42 is also provided with an adjusting sleeve 53, which is fitted onto the outer peripheral wall of multiple clamping blocks 51. The adjusting strip and multiple clamping blocks 51 are threadedly matched. At the same time, in order to facilitate medical staff to insert the clamping block 5 into the clamping cavity 52, the clamping block 5 is spherical. When medical staff need to replace the outer sleeve 1 separately, they loosen the adjusting sleeve 53 to release the clamping block 5 from the multiple clamping blocks 51. At this time, the medical staff can pull the clamping block 5 out of the clamping cavity 52, thereby realizing the disassembly of the connecting strip 42 and the outer sleeve 1. This makes it convenient for medical staff to replace and discard the outer sleeve 1 separately, saving resources.
[0039] In other embodiments, the ends of the handle 11 and the connecting strip 42 that are close to each other can be made into magnets, so that the connecting strip 42 can be fixed and disassembled by magnetic attraction, but the cost will be slightly higher.
[0040] Meanwhile, in some cases, it is not necessary to use endoscope 2; medical staff can simply insert the outer tube 1 to perform digital and visual examinations. Therefore, refer to Figure 4 The outer sleeve 1 is a transparent sleeve, and a first light guide tube 6 is fixedly embedded on the inner wall of the outer sleeve 1. There are multiple sets of first light guide tubes 6, which are arranged at intervals along the circumference of the outer sleeve 1. The handle 11 is provided with a first light supply element 61 that supplies light to the inside of the first light guide tube 6. In this application, the first light supply element 61 is an LED cold light source, and the first light guide tube 6 is an LED light guide tube. In this way, when performing visual inspection or finger inspection, the light is provided to medical staff, which is convenient for medical staff to observe. At the same time, the first light guide tube 6 itself does not emit light, and the LED cold light source is placed outside the body to reduce the impact of the LED cold light source emitting light inside the body on the internal tissues.
[0041] Similarly, the endoscope 2 is also provided with a second light guide tube 62. The operating end of the endoscope 2 is provided with a second light supply element 63 that supplies light into the second light guide tube 62. The second light guide tube 62 and the first light guide tube 6 are the same LED light guide tubes. At the same time, the second light supply element 63 and the first light supply element 61 are the same LED cold light source.
[0042] The implementation principle of the anorectal endoscope system with night vision function in this application embodiment is as follows: When performing anorectal examinations or surgeries, the medical staff first inserts the lubricated outer sleeve 1 into the patient's anus. Then, the medical staff clamps the fixing ring 41 onto the bed 12 and adjusts the angle of the connecting strip 42 until the end of the connecting strip 42 corresponds to the handle 11. Then, the medical staff inserts the clamping block 5 into the clamping cavity 52 and rotates the adjusting sleeve 53 to fix the position of the outer sleeve 1 and the bed 12. Then, the medical staff inserts the endoscope 2 into the patient's body along the outer sleeve 1. At this time, the second light supply element 63 supplies light into the second light guide tube 62. The medical staff only needs to operate the endoscope 2 with one hand and mark the lesion on the monitor with the other hand. The operation is simple.
[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
