Endoscope, handle housing thereof, and operation handle thereof

Abstract

The present application belongs to the technical field of medical instruments, and specifically relates to an endoscope, a handle housing thereof, and an operation handle thereof. A side wall of the handle housing comprises a first portion. A proximal end of the first portion is connected to a proximal end wall of the handle housing. At least a part of an outer peripheral surface of the first portion forms a gripping area. A partial area at a proximal end of the gripping area is recessed to form a first finger placement position. A portion of the handle housing other than the first portion is provided with a first mounting hole and a second mounting hole. The first mounting hole is used for mounting a wire harness connector, and the second mounting hole is used for mounting a suction assembly. In the present application, the first mounting hole and the second mounting hole are formed on the portion of the handle housing other than the first portion. That is to say, the first portion of the present application only needs to provide a gripping space for medical staff, without the need to provide a mounting space for the wire harness connector or the suction assembly. Obviously, this can reduce the length dimension of the first portion, thereby shortening the handle housing, facilitating operation by medical staff and the storage and transportation of the sputum suction endoscope, and reducing the cost of the sputum suction endoscope.

Description

Endoscope and its handle housing, operating handle Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to an endoscope and its handle housing and operating handle. Background Technology

[0002] Suctioning is a routine clinical procedure. It usually refers to the removal of secretions from the respiratory tract through the mouth, nose, or artificial airway to maintain airway patency and prevent complications such as aspiration pneumonia, atelectasis, and suffocation.

[0003] Currently, suction endoscopes are commonly used for sputum suctioning, but their ease of use is poor. Improving the ease of use of suction endoscopes is an urgent problem to be solved in this field. Utility Model Content

[0004] The purpose of this application is to provide an endoscope and its handle housing and operating handle, which can solve the problem of poor usability of current endoscopes such as suction endoscopes.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application provides a handle housing for an endoscope, the sidewall of which includes a first part, the proximal end of which is connected to the proximal wall of the handle housing;

[0007] At least a portion of the outer peripheral surface of the first part forms a gripping area, and a portion of the area near the gripping area is recessed to form a first finger placement position;

[0008] The handle housing, excluding the first part, has a first mounting hole and a second mounting hole. The first mounting hole is used to install a wire harness connector, and the second mounting hole is used to install a suction assembly.

[0009] Secondly, this application provides an operating handle for an endoscope, including the aforementioned handle housing.

[0010] Thirdly, this application provides an endoscope including the operating handle as described above.

[0011] The beneficial technical effects of this application are as follows:

[0012] In this application, the first mounting hole and the second mounting hole are located on the part of the handle housing other than the first part. That is to say, the first part of this application only needs to provide a gripping space for medical staff, without providing a mounting space for the wire harness connector or suction assembly. Obviously, this can reduce the length of the first part, thereby shortening the handle housing, which is conducive to the operation of medical staff, as well as the storage and transportation of the endoscope, and reduces the cost of the endoscope.

[0013] In addition, a portion of the proximal area of ​​the gripping region of this application is recessed to form a first finger placement position. The recessed design of the first finger placement position can improve the gripping comfort of medical staff and reduce hand fatigue caused by prolonged operation. Furthermore, the recessed design can provide axial stop and limit for the fingers of medical staff, preventing the hand from sliding relative to the handle housing during the operation, thereby improving the accuracy of the operation.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The endoscope, its handle housing, and its operating handle provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0024] In the various embodiments of this application, "proximal end" and "distal end" refer to the position of the endoscope and its components relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0025] As shown in the patent document with patent publication number CN220572177U, the operating handle of the current suction endoscope includes a handle housing, on which a wire harness connector and a suction component are installed. The wire harness connector is electrically connected to a camera module located at the distal end of the insertion part, and the suction component is connected to the insertion part, thereby suctioning out secretions from the human body.

[0026] The inventors discovered that the current suction endoscope handle housing has a first part on its sidewall. The proximal end of the first part connects to the proximal wall of the handle housing, and the outer peripheral surface of the first part forms a gripping area. To prevent interference between the wiring harness connector and the gripping area, the gripping area is separated from the proximal wall of the handle housing, and the wiring harness connector is located in the area of ​​the first part between the gripping area and the proximal wall of the handle housing. It is evident that the current first part of the handle housing not only needs to provide gripping space for medical personnel but also needs to provide installation space for the wiring harness connector. This results in a relatively long first part, leading to an increased size of the handle housing. A longer operating handle is not only detrimental to medical personnel operation (i.e., poor usability) and the storage and transportation of the suction endoscope, but also increases the cost of the suction endoscope.

[0027] As shown in Figures 1 to 5, this application discloses an endoscope handle housing. The sidewall of the handle housing includes a first part 100, the proximal end of which is connected to the proximal wall of the handle housing. Specifically, the handle housing includes a sidewall and a proximal wall, both of which have a certain thickness. A hollow receiving space is formed within the sidewall, and both ends of the receiving space are open. The proximal wall of the handle housing is connected to the proximal end of the first part 100 to cover the proximal opening of the sidewall.

[0028] At least a portion of the outer peripheral surface of the first part 100 forms a gripping area, and a portion of the gripping area proximal to the gripping area is recessed to form a first finger placement position 111. Specifically, when a medical professional grips the handle housing, if the medical professional's thumb is pointing towards the distal end of the handle housing, the first finger placement position 111 is used to accommodate at least the little finger and ring finger; if the medical professional's thumb is pointing towards the proximal end of the handle housing, the first finger placement position 111 is used to accommodate at least the middle finger and index finger.

[0029] The handle housing, excluding the first part 100, has a first mounting hole 210 and a second mounting hole 220. The first mounting hole 210 is used to mount the wire harness connector 410, and the second mounting hole 220 is used to mount the suction assembly 420. Specifically, the handle housing, excluding the first part 100, includes a proximal wall of the handle housing, and both the first mounting hole 210 and the second mounting hole 220 may be located on the proximal wall of the handle housing. In addition, the handle housing typically includes a second part 300 for mating with the insertion part 500. Both the first mounting hole 210 and the second mounting hole 220 may be located on the second part 300, or one of the first mounting hole 210 and the second mounting hole 220 may be located on the proximal wall of the handle housing, and the other may be located on the second part 300.

[0030] Optionally, the wiring harness connected to the camera module inside the insertion part 500 can enter the handle housing through the insertion part 500 and connect to the wiring harness connector 410 installed in the first mounting hole 210. The wiring harness connector 410 can be used to electrically connect to a display device to display the image captured by the camera module. The wiring harness connector 410 can be a Type-C connector, a USB connector, an integrated connector, or other electrical connectors. This application does not impose specific limitations on this. When the wiring harness connector 410 is a Type-C connector or a USB connector, the wiring harness located near the wiring harness connector 410 can be reused, which can save the cost of using the endoscope.

[0031] In this application, the first mounting hole 210 and the second mounting hole 220 are located on the part of the handle housing other than the first part 100. That is to say, the first part 100 of this application only needs to provide a gripping space for medical staff, without providing a mounting space for the wire harness connector 410 or the suction assembly 420. Obviously, this can reduce the length of the first part 100, thereby shortening the handle housing, which is conducive to the operation of medical staff (improving ease of use) and the storage and transportation of the endoscope, and reduces the cost of the endoscope.

[0032] In addition, a portion of the proximal area of ​​the gripping region of this application is recessed to form a first finger placement position 111. The recessed design of the first finger placement position 111 can improve the gripping comfort of medical staff and reduce hand fatigue caused by long-term operation. Furthermore, the recessed design can provide axial stop and limit for the fingers of medical staff to prevent the hand from sliding relative to the handle housing during the operation, thereby improving the accuracy of the operation.

[0033] In one optional embodiment, the suction assembly 420 includes a negative pressure nozzle 421 and an atmospheric connector 422. The second mounting hole 220 includes a first sub-hole 221 and a second sub-hole 222. The first sub-hole 221 is used to install the negative pressure nozzle 421, and the second sub-hole 222 is used to install the atmospheric connector 422. Specifically, the negative pressure nozzle 421 can be connected to a negative pressure device, and the insertion part 500 of the endoscope can be inserted into the patient's body. When the negative pressure device is working, lesions and other foreign objects in the human body can be discharged through the negative pressure nozzle 421. The two ends of the atmospheric connector 422 are respectively connected to the atmosphere and the negative pressure nozzle 421. When the atmospheric connector 422 is cut off, lesions and other foreign objects in the human body can be discharged through the negative pressure nozzle 421. When the atmospheric connector 422 is open, the negative pressure nozzle 421 is connected to the atmosphere, and thus lesions and other foreign objects in the human body cannot be discharged through the negative pressure nozzle 421.

[0034] The handle housing also includes a second part 300 for connection with the insertion part 500 of the endoscope. The second part 300 is located on the far side of the first part 100 and is connected to the first part 100. A second sub-hole 222 is provided in the second part 300, and the second sub-hole 222 and the first finger placement position 111 are located on opposite sides of the handle housing.

[0035] When medical personnel hold the handle housing of this embodiment, they can place their little finger and ring finger on the first finger placement position 111, so that the thumb faces the far end of the handle housing. When adopting this grip posture, the thumb and the first finger placement position 111 will be located on opposite sides of the handle housing (for example, the upper and lower sides of Figure 1). The first finger placement position 111 and the second sub-hole 222 are also located on opposite sides of the handle housing. Therefore, when adopting this grip posture, the position of the thumb corresponds exactly to the position of the second sub-hole 222. By pressing the atmospheric connector 422 located in the second sub-hole 222 with the thumb, the on / off state of the atmospheric connector 422 can be controlled. This is more ergonomic and simple to operate.

[0036] In one optional embodiment, the first sub-hole 221 is located on the proximal wall of the handle housing. If the first sub-hole 221 is located in the second part 300, and the axis of the first sub-hole 221 is perpendicular or nearly perpendicular to the axis of the handle housing, then after the negative pressure nozzle 421 is installed into the first sub-hole 221, the axis of the negative pressure nozzle 421 will also be perpendicular or nearly perpendicular to the axis of the handle housing. This would result in a near-90-degree bend in the flow channel formed by the negative pressure nozzle 421 and the insertion part 500, which would reduce suction efficiency. However, in this embodiment, since the first sub-hole 221 is located on the proximal wall of the handle housing, the axis of the first sub-hole 221 is not perpendicular to the axis of the handle housing. Therefore, the flow channel formed by the negative pressure nozzle 421 and the insertion part 500 does not have a 90-degree bend, thereby improving suction efficiency. Except for this embodiment, the first sub-hole 221 and the second sub-hole 222 can both be provided in the second part 300 or both can be provided in the proximal wall of the handle housing, or the first sub-hole 221 can be provided in the second part 300 and the second sub-hole 222 can be provided in the proximal wall of the handle housing. This application does not limit the setting position of the first sub-hole 221 and the second sub-hole 222 in the part of the handle housing other than the first part 100.

[0037] In the two embodiments described above, the second mounting hole 220 contains two holes. In other embodiments, the second mounting hole 220 may contain only one hole. In this case, the negative pressure nozzle 421 can be installed into the second mounting hole 220, and then a through hole can be opened on the negative pressure nozzle 421 to install the atmospheric connector 422 into the through hole.

[0038] In one optional embodiment, the distal end of the second part 300 has a docking hole 310 that mates with the insertion part 500, and the first sub-hole 221 is coaxially arranged with the docking hole 310. In this embodiment, the first sub-hole 221 and the docking hole 310 are coaxially arranged. Thus, after connecting the insertion part 500 to the docking hole 310 and the negative pressure nozzle 421 to the first sub-hole 221, the negative pressure nozzle 421 and the insertion part 500 will be coaxially arranged. This allows the flow channel formed between the negative pressure nozzle 421 and the insertion part 500 to extend in a straight line, eliminating bends between them. This ensures that lesions and other foreign objects can flow smoothly during suction, preventing accumulation of lesions and other foreign objects in the flow channel and improving the suction efficiency of lesions and other foreign objects. Of course, the axes between the first sub-hole 221 and the docking hole 310 can also be parallel to each other or relatively inclined; this application does not limit this.

[0039] In one alternative embodiment, a portion of the near end of the grip area protrudes outward to form a support convex surface 112, and the support convex surface 112 and the first finger placement position 111 are located on opposite sides of the handle housing.

[0040] In this embodiment, the supporting convex surface 112 and the first finger placement position 111 are located on opposite sides of the handle housing. When medical staff hold the operating handle, the supporting convex surface 112 can be used to support the palm of the hand to reduce the burden on the hand muscles and reduce fatigue.

[0041] Furthermore, when this embodiment is combined with the embodiment in which "the second sub-hole 222 is located in the second part 300, and the second sub-hole 222 and the first finger placement position 111 are respectively located on opposite sides of the handle housing", the second sub-hole 222 and the support convex surface 112 are located on the same side of the handle housing, and the second sub-hole 222 is located on the far side of the support convex surface 112. When medical personnel hold the handle housing of this embodiment, they can place their little finger and ring finger on the first finger placement position 111, so that the thumb is facing the far end of the handle housing. When adopting this grip posture, the palm and the support convex surface 112 are on the same side, and the hand will be raised by the support convex surface 112, thereby raising the thumb. In this way, the thumb is placed on the atmospheric connector 422 from top to bottom, so that the atmospheric connector 422 can be pressed without lifting the thumb upward, which can improve the comfort of operation.

[0042] In one optional embodiment, the supporting convex surface 112 is a supporting arc surface. The arc surface design can increase the contact area between the palm and the handle housing, improving stability during operation; and the raised arc surface can better fit the natural curve of the palm, providing a more comfortable grip.

[0043] In one alternative embodiment, a portion of the gripping area protrudes outward to form a second finger placement position 113, which is connected to and located distal to the first finger placement position 111.

[0044] When medical personnel hold the handle housing of this embodiment, they can place their little finger and ring finger in the first finger placement position 111 and their index finger and middle finger in the second finger placement position 113. Since the area where the index finger and middle finger are placed is convex outward, the convex structure can serve as a support point to help medical personnel hold the handle better; and the convex structure can serve as a marker point to guide medical personnel to place their fingers in the correct position.

[0045] And / or, in an alternative embodiment, the first mounting hole 210 is provided on the proximal wall of the handle housing, thus facilitating the connection of an external display.

[0046] In one optional embodiment, the grip area is provided with an anti-slip structure 114. This anti-slip structure 114 increases the friction between the palm and the handle housing, thereby preventing the palm from slipping relative to the handle housing. The anti-slip structure 114 can be an anti-slip protrusion or an anti-slip groove. It should be noted that this embodiment can be implemented independently of the next embodiment. Of course, the grip area may also not have the anti-slip structure 114, and this application does not limit this.

[0047] In a further embodiment, the anti-slip structure 114 and the first finger placement position 111 are located on the same side of the handle housing. This embodiment designs the anti-slip structure 114 on the side of the handle housing where the fingers are placed, allowing the fingers to grip the handle housing more firmly and preventing accidental operation due to slippage. Furthermore, when the hand grips the handle, the main force is usually concentrated on the fingers; the anti-slip structure 114, positioned corresponding to the fingers, effectively enhances friction, thereby improving grip stability. Of course, the anti-slip structure 114 and the first finger placement position 111 can also be located on opposite sides of the handle housing.

[0048] This application also discloses an endoscope operating handle, including the handle housing of any of the above embodiments, thus enabling the operating handle to possess the beneficial effects of the aforementioned handle housing, which will not be elaborated further here.

[0049] This application also discloses an endoscope, including the operating handle as described above. The endoscope referred to in this application can be a suction endoscope, bronchoscope, nephroscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This application does not specifically limit the type of endoscope.

[0050] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
