Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a cystoscope supporting device and a one-handed fixing piece. Background Art

[0002] In urological surgery, biopsy forceps, stone removal nets, lasers and other instruments are often used in conjunction with cystoscopy for auxiliary treatment.

[0003] During the existing cystoscopic operation, the attending physician can operate the cystoscope alone, usually by using his right hand to manipulate the operating part and his left hand to support the cystoscope, so as to extend the front end of the cystoscope from the patient's urethra into the body. Different purposes are achieved by selecting soft or hard endoscopes for surgical operations according to the actual surgical location requirements. Another operator presses and supports additional surgical instruments through the instrument channel of the cystoscope into the patient's body. During the entire operation, at least two or more operators are required to perform the operation on the patient. On the one hand, this increases the personnel cost of the operation, and on the other hand, the tacit understanding of multiple people cannot be fully matched, which may indirectly increase the operational risk of the operation.

[0004] Existing cystoscopes must be disinfected after use to prevent secondary infections between patients. Furthermore, the front end of a cystoscope often has a snake-like structure, making disinfection difficult or impossible to perform thoroughly, significantly increasing the cost of using a cystoscope.

[0005] In order to reduce the cost of disinfection and the waiting time of patients, the cost of using a cystoscope is reduced by adding a new type of outer cover.

[0006] Therefore, there is a need for a device that can combine and fix existing urological surgical instruments and the like with a new type of outer sleeve to ensure that an operator can operate the instrument with one hand alone. Summary of the Invention

[0058] like Figure 1 FIG. 1 illustrates a cystoscope accessory device according to a preferred embodiment of the present invention. The cystoscope accessory device includes a one-handed fixing component 1 and a matching body 3. The cystoscope accessory device is used to accommodate multiple surgical instruments 2. The one-handed fixing component 1 is mounted on the matching body 3. In other words, the surgical instruments 2 are secured by the one-handed fixing component to complete the surgical procedure.

[0059] In one embodiment of the present invention, the one-handed fixing member 1 is detachably mounted on the tail of the supporting body 3. In another embodiment of the present invention, the one-handed operation member 1 is integrally fixed to the tail of the supporting body 3.

[0060] For ease of explanation, during the surgical procedure, the side extending into the patient's body is defined as the front, and the side located outside the patient's body is defined as the back.

[0061] The surgical instrument 2 is embodied as a biopsy forceps 21, a stone removal net 22, and a laser 23. The biopsy forceps 21 is suitable for clamping pathological tissue for biopsy analysis; the stone removal net 22 is used to capture and remove ureteral stones under endoscopy; and the laser is suitable for cutting ureteral stones, especially large ones. In other words, the surgical instrument 2 has various functions. During surgery, the surgical instrument 2 is installed in the one-handed fixture 1 and is fixedly connected to the one-handed fixture 1.

[0062] The matching body 3 includes a jacket 31, an instrument channel 32, and a visual channel 33. The jacket 31 includes a front portion 311 and a rear portion 312. The front portion 311 extends into the patient's body, while the rear portion 312 is located outside the patient's body. The diameter of the front portion 311 is smaller than that of the rear portion 312; in other words, the front portion 311 is narrower than the rear portion 312. In other words, the narrowness of the front portion 311 facilitates its extension into the patient's body. The rear portion 312 is wider, making it easier for the operator to grip and operate. The instrument channel 32 and the visual channel 33 are disposed in the jacket 31. The instrument channel 32 extends from the side end of the jacket 31 to and through the front portion 311. The visual channel 33 extends from the rear portion 312 to the front portion 311. During surgery, the surgical instrument 2 passes through the one-handed fixture 1 and the instrument channel 32 in sequence.

[0063] The one-handed fixing member 1 is arranged behind the surgical instrument 2 entrance of the supporting body, so as to facilitate the control of the surgical instrument 2 near the surgical instrument entrance. The one-handed fixing member 1 is arranged behind the entrance of the instrument channel 2.

[0064] The surgical instrument 2 includes a tip 24, an extension 25, a grip 26, and an operating end 27. The rear end of the tip 24 is connected to the extension 25, and the front end of the grip 26 is connected to the extension 25, and the rear end is connected to the operating end 27. The tip 24 is a functional end that performs different functions. When the surgical instrument 2 is implemented as the biopsy forceps 21, the tip 24 is suitable for clamping pathological tissue; when the surgical instrument 2 is implemented as the stone removal net 22, the tip 24 is suitable for sleeve removal of stones; when the surgical instrument 2 is implemented as the laser 23, the tip 24 is suitable for crushing and cutting large stones. The extension 25 is implemented as a bendable tubular shape. That is, the extension 25 enters from the instrument channel 32 and advances into the patient's body along with the bending of the front part 311.

[0065] The grip portion 26 provides the operator with gripping space, and the operating end 27 provides the operator with operating space. When the surgical instrument 2 is mounted on the one-handed fixture 1, the surgical instrument 2 and the supporting body 3 are fixed relative to each other. Specifically, the grip portion 26 is fixed to the one-handed fixture 1. The operator can control the movement of the supporting body 3 while holding the grip portion 26. By controlling the operating end 27, the operator can achieve dual control of the supporting body 3 and the surgical instrument 2, achieving single-handed control.

[0066] The one-handed fixing device 1 includes an accessory body 11 and a fixing member 12, and has an instrument opening 13. The accessory body 11 provides a fixing space, and the fixing member 12 is connected to the accessory body 11 at one end and to the rear portion 312 of the outer sleeve 31 at the other end. The instrument opening 13 is provided at the front and rear end surfaces of the accessory body 11. In other words, the instrument opening 13 extends from the front end surface to the rear end surface of the accessory body 11. When the surgical instrument 2 is mounted on the one-handed fixing device 1, the accessory body 11 surrounds the gripping portion 26 of the surgical instrument 2. The fixing member 12 keeps the gripping portion 26 fixed relative to the outer sleeve 31. The distal end 24 and the extension portion 25 of the surgical instrument 2 pass through the instrument opening 13 in sequence and extend into the instrument channel 32.

[0067] The fixing member 12 is adapted to be arranged at the rear end of the supporting body 3 , and is located adjacent to the rear of the entrance of the instrument channel 32 of the supporting body 3 .

[0068] The accessory body 11 includes an inner portion 111 and an outer portion 112. The grip portion 26 of the surgical instrument 2 engages with the inner portion 111, and the outer portion 112 is connected to the fixing member 12. The outer portion 112 is detachably connected to the fixing member 12. In other words, the one-handed fixing member 1 is detachably mounted to the rear portion 312 of the outer cover 31. Meanwhile, the fixing member 12 is movably connected to the rear portion 312 of the outer cover 31. In other words, the one-handed fixing member 1 is movably connected to the side end of the accessory body 3.

[0069] It is worth mentioning that the fixing member 12 includes a connecting component 121, a fixing member 122 and a movable component 123. In this embodiment, the fixing member 122 is fixed to the rear portion 312 of the outer sleeve 31. The fixing member 122 is implemented in a circular ring shape, and the fixing member 122 surrounds the rear portion 312 of the matching body 3. The fixing member 122 is adjustably installed at the rear end of the matching body 3. In other words, the fixing member 122 can be radially adjusted in size according to the outer diameter of the matching body 3. In other words, through the fixation of the fixing member 122, the accessory body 11 can remain relatively fixed to the outer sleeve 31.

[0070] The connecting component 121 is connected to the fixing member 122 and extends outward, and the movable component 123 is movably connected to the connecting component 121. In other words, the connecting component 121 plays the role of connecting and receiving, and the movable component 123 plays the role of movably adjusting the position relationship.

[0071] Specifically, the connecting assembly 121 includes a first connecting unit 1211, which is integrally connected to the fixing member 122. In other words, the first connecting unit 1211 protrudes from the plane where the rear portion 312 of the outer sleeve 31 is located. The connecting assembly 121 also includes a second connecting unit 1212 and a connecting rod 1213. The second connecting unit 1212 is integrally connected to the connecting rod 1213. In this embodiment, the connecting rod 1213 is movably connected to the first connecting unit 1211. In other words, one end of the connecting rod 1213 is connected to the first connecting unit 1211, and the other end is connected to the second connecting unit 1212. The second connecting unit 1212 is movably connected to the accessory body 11. In other words, one end of the second connecting unit 1212 is connected to the accessory body 11, and the other end is connected to the connecting rod 1213.

[0072] The movable component 123 is arranged at the intersection of the connecting component 121. Specifically, the movable component 123 includes a first movable member 1231 and a second movable member 1232. In this embodiment, the first movable member 1231 and the second movable member 1232 are implemented as spherical parts to achieve a universal steering function. The first movable member 1231 is integrally connected to the connecting rod 1213. In other words, the first movable member 1231 is arranged between the first connecting rod 1213 and the fixed member 122. In other words, the connecting rod 1213 is movably connected to the first connecting unit 1211 through the first movable member 1231.

[0073] The second movable member 1232 is integrally connected to the accessory body 11. In other words, the second movable member 1232 is disposed between the accessory body 11 and the connecting rod 1213. In other words, the accessory body 11 is movably connected to the second connecting unit 1212 via the second movable member 1232.

[0074] It is worth mentioning that the fixing member 12 has a first limiting groove 124 and a second limiting groove 125. The first limiting groove 124 is provided in the first connecting unit 1211, and the second limiting groove 125 is provided in the second connecting unit 1212. In other words, the first limiting groove 124 is located between the fixing member 122 and the connecting rod 1213, and the second limiting groove 125 is located between the connecting rod 1213 and the accessory body 11. In other words, the connecting rod 1213 is connected to the fixing member 122 by the first movable member 1231 engaging with the first limiting groove 124. The accessory body 11 is connected to the connecting rod 1213 by the second movable member 1232 engaging with the second limiting groove 125. In this embodiment, the first limiting groove 124 and the second limiting groove 125 are implemented as spherical grooves, that is, the first movable member 1231 and the second movable member 1232 can be fully engaged with the first limiting groove 124 and the second limiting groove 125 respectively.

[0075] In particular, when the first movable member 1231 is engaged with the first limiting groove 124 and the second movable member 1232 is engaged with the second limiting groove 125, the first movable member 1231 and the second movable member 1232 can drive the integrally connected connecting rod 1213 and the accessory body 11 to swing omnidirectionally. In other words, the one-handed fixing member 1 achieves the purpose of adjusting the accessory body to any angle through the rolling engagement between the movable member 123 and the first limiting groove 124 and the second limiting groove 125, so that the operator can single-handedly operate the surgical instrument 2 fixed to the one-handed fixing member 1 while controlling the supporting body 3.

[0076] When the operator operates with one hand, the connecting rod 1213 is controlled to be parallel to the rear portion 312 of the outer sleeve 31, so that the accessory body 11 is close to the outer sleeve 31. Then, the surgical instrument 2 mounted on the one-handed fixing member 1 can smoothly extend the extension portion 25 into the instrument channel 32.

[0077] Specifically, in this embodiment, the one-handed fixing device 1 has multiple instrument openings 13 disposed within the interior 111 of the accessory body 11. Each instrument opening 13 corresponds to a surgical instrument 2 of a different size. Specifically, the instrument openings 13 include a first instrument opening 131, a second instrument opening 132, and a third instrument opening 133. The diameters of the first, second, and third instrument openings 131, 132, and 133 decrease in order, that is, the diameters of the first, second, and third instrument openings 131, 132, and 133 each vary. The first, second, and third instrument openings 131, 132, and 133 are arranged in parallel and extend from the rear end of the accessory body 11 to the front end.

[0078] In this embodiment, the diameter of the first instrument opening 131 corresponds to the diameter of the biopsy forceps 21. That is, when the biopsy forceps 21 is mounted on the one-handed fixture 1, the grip portion 26 is engaged with the first instrument opening 131. When the stone removal net 22 is mounted on the one-handed fixture 1, the grip portion 26 is engaged with the second instrument opening 132. When the laser 23 is mounted on the one-handed fixture 1, the grip portion 26 is engaged with the third instrument opening 133. In other words, when the surgical instrument 2 is implemented as the biopsy forceps 21, the stone removal net 22, and the laser 23, the instrument openings 13 through which the surgical instrument 2 is allowed to pass correspond to the first instrument opening 131, the second instrument opening 132, and the third instrument opening 133, respectively.

[0079] The supporting body 3 further includes an operating portion 34 and a buckle. The operating portion 34 is disposed on the rear portion 312 of the outer shell 31. The operating portion 34 is crescent-shaped and surrounds half of the rear portion 312 of the outer shell 31. The buckle is disposed on the rear portion 312 of the outer shell 31.

[0080] It is worth noting that a cystoscope 4 is adapted to be nested within the supporting body 3. In other words, the cystoscope 4 is adapted to be installed within the supporting body 3. The operating unit 34 is connected to the cystoscope 4; in other words, the movement of the cystoscope 4 is achieved by controlling the operating unit 34. When the cystoscope 4 is installed in the supporting body 3, it is secured by the snap fastener. In other words, the snap fastener secures the relative position of the cystoscope 4 and the supporting body 3.

[0081] Furthermore, the cystoscope 4 includes a cystoscope body 44, which provides an installation space. The cystoscope 4 also includes a functional component 41, a gripping component 42, and a control component 43. The functional component 41 is disposed at the front end of the cystoscope body 44, the gripping component 42 is disposed at the rear end of the cystoscope body 44, and the control component 43 is disposed at the front end of the cystoscope body 44.

[0082] The functional component includes a pair of optical fibers 411, a visual unit 412, and a pair of separators 413. The optical fibers 411 are arranged on the front end surface of the cystoscope body 44, and the visual unit 412 is arranged on the front end surface of the cystoscope body 44. The separator 413 is arranged on the front end surface of the cystoscope body 44. In this embodiment, the optical fibers 411 are arranged on both sides of the visual unit 412, and the visual unit 412 is arranged at the center of the front end surface of the cystoscope body 44. A separator 413 is arranged between each of the optical fibers 411 and the visual unit 412. The separator 413 is implemented as a soft separator, the visual unit 412 provides a visual function, and the optical fibers 411 provide a lighting function. The separator 413 is arranged between the visual unit 412 and the optical fibers 411 to prevent light from being reflected into the camera and affecting the field of view.

[0083] The control member 43 further includes a bendable member 431 and a transmission member 432. The bendable member 431 is integrally connected to the front end of the cystoscope body 44. In this embodiment, the bendable member 431 is implemented as a snake-bone member. That is, the cystoscope 4 is bendable and extendable via the bendable member 431. Furthermore, the transmission member 432 is disposed within the bendable member 431. The gripping member 42 includes a dial 422 and a slot. The dial 422 is disposed at the rear end of the cystoscope 4 and is linked to the bendable member 431. When the cystoscope 4 is mounted on the supporting body 3, the dial 422 engages with the operating portion 34. In other words, the dial 422 protrudes from the cystoscope body 44. The cystoscope 4 engages within the supporting body 3 via the slot. Specifically, the card slot of the cystoscope 4 corresponds to the buckle of the matching body 3. That is, the cystoscope 4 is connected to the matching body 3 by the buckle being engaged with the card slot.

[0084] Furthermore, the front end of the transmission member 432 is connected to both sides of the front end surface of the bendable member 431, and the other end is connected to the dial 422. In other words, the operator can adjust the degree of bending of the bendable member 431 by controlling the operating part 34.

[0085] Thus, when the operator manipulates the operating portion 34 to control the bendable member 431 to bend, the operator simultaneously controls the operating end 27 of the surgical instrument 2 fixed to the one-handed fixing member 1 to operate the surgical instrument 2. The entire operation process is performed by one operator with one hand.

[0086] As shown in Figure 7, it is an optional variation of the supporting body 3A and the cystoscope 4A. Specifically, the supporting body 3A includes a jacket 31 and has an instrument channel 32 and a visual channel 33. The instrument channel 32 extends from the rear end side of the jacket 31 to the front end face of the jacket 31, and the visual channel 33 extends forward from the rear end of the jacket 31 to the front end face of the jacket 31, but does not penetrate. In other words, the front end face of the visual channel 33 is at a certain distance from the front end face of the jacket 31. A transparent material is provided between the two to facilitate the subsequent insertion of the cystoscope 4A to obtain a surgical field of view.

[0087] In addition, the supporting body 3A also includes a pair of optical fibers 411A, which are disposed on the front end of the outer sleeve 31. That is, when the supporting body 3A is sleeved onto the cystoscope 4A and extended along the patient's ureter, the optical fibers 411A located at the front end of the outer sleeve 31 provide the operator with light, facilitating the operator's observation field and insertion and extension.

[0088] Unlike the previous embodiment, the cystoscope 4A includes a cystoscope body 44, a functional component 41, and a visual unit 412 disposed separately on the front end of the cystoscope body 44. In other words, the cystoscope 4A provides only visual function and does not provide lighting. The supporting body 3A provides lighting.

[0089] It is worth mentioning that the instrument channel 32 leads to the surgical instrument 2, and the visual channel 33 leads to the cystoscope 4A, and the instrument channel 32 and the visual channel 33 are independently spaced apart from each other. That is, the instrument channel 32 and the visual channel 33 are not connected to each other. Therefore, when the supporting body 3A is sleeved on the cystoscope 4, only the supporting body 3A is in contact with the patient's body. The cystoscope 4A does not directly contact the patient's body. Since the manufacturing cost of the cystoscope 4A is relatively high, avoiding contact with the patient to reduce the disinfection operation further reduces the use cost of the cystoscope 4A. In other words, the supporting body 3A is disposable and can be thrown away after use without the need for additional disinfection costs.

[0090] like Figure 9FIG2 shows an overall schematic diagram of a second preferred embodiment of the present invention. Unlike the previous embodiment, the one-handed fixing device 1B has been modified. Specifically, the one-handed fixing device 1B comprises an accessory body 11B and a fixing member 12, as well as multiple instrument ports 13B. The accessory body 11B is connected to the mating body 3 via the fixing member 12, which secures the accessory body 11B relative to the mating body 3. Unlike the previous embodiment, the arrangement of the instrument ports 13B has been modified.

[0091] Specifically, the instrument openings 13B include a first instrument opening 131B, a second instrument opening 132B, and a third instrument opening 133B. The first, second, and third instrument openings 131B, 132B, 133B are arranged vertically. That is, the first, second, and third instrument openings 131B, 132B, 133B are located on the same axis. The instrument openings 13B are arranged from back to front of the accessory body 11B as the first, second, and third instrument openings 131B, 132B, 133B. In other words, the instrument openings 13B are arranged from larger to smaller from the rear end to the front end of the accessory body 11B. In other words, the instrument openings 13B extend through the accessory body 11 in a stepped pattern.

[0092] Since the sizes of the instrument opening 13B are different, in order to accommodate the surgical instruments of different radial sizes, generally, when the surgical instrument 2 is implemented as a biopsy forceps 21, when the biopsy forceps 21 is installed on the one-handed fixture 1, the gripping portion 26 of the biopsy forceps 21 is engaged with the first instrument opening 131. When the surgical instrument 2 is implemented as a stone removal net 22, when the stone removal net 22 is installed on the one-handed fixture 1, the gripping portion 26 of the stone removal net 22 is engaged with the second instrument opening 132. When the surgical instrument 2 is implemented as a laser 23, when the laser 23 is installed on the one-handed fixture 1, the gripping portion 26 of the laser 23 is engaged with the third instrument opening 133. In other words, the surgical instruments 2 of different implementations can be adaptively installed on the instrument openings 13 of different radial lengths.

[0093] like Figure 12 FIG2 shows an overall schematic diagram of a one-handed fixation device 1C according to a third preferred embodiment of the present invention. The one-handed fixation device 1C comprises an accessory body 11C, a fixing member 12, and at least one instrument port 13C. One end of the fixing member 12 is connected to the accessory body 11C, and the other end is connected to the outer sleeve 31 of the mating body 3. The instrument port 13C is provided on the accessory body 11C and is adapted to allow passage of a surgical instrument 2.

[0094] Specifically, when the surgical instrument 2 is implemented as a biopsy forceps 21, the accessory body 11C is implemented as a circular ring with a larger diameter, and correspondingly, a first instrument opening 131 with a larger diameter is allowed to pass through the biopsy forceps 21. The accessory body 11C can be replaced by an accessory body 11D and an accessory body 11E. When the surgical instrument 2 is implemented as a stone removal net 22, the accessory body 11D is implemented as a circular ring with a medium diameter, and correspondingly, a second instrument opening 132 with a medium diameter is allowed to pass through the stone removal net 22. When the surgical instrument 2 is implemented as a laser 23, the accessory body 11E is implemented as a double-layer coaxial circular ring with a smaller diameter, and correspondingly, a third instrument opening 133 with the smallest diameter is allowed to pass through the laser 23.

[0095] The fixing member 12 includes a connecting rod 1213, a first connecting unit 1211, and a second connecting unit 1212. One end of the connecting rod 1213 is movably connected to the first connecting unit 1211 via a first movable member 1231, and the other end is movably connected to the second connecting unit 1212 via a second movable member 1232. The fixing member 122 is securely connected to a cover 31 of the accessory body 3. The first connecting unit 1211 is integrally connected to the fixing member 122. The second connecting unit 1212 is integrally connected to the accessory body 11C. The connecting rod 1213 movably adjusts the positional relationship between the surgical instrument 2 and the cover 31, allowing the operator to simultaneously control the bending and extension of the accessory body 3 while controlling the surgical instrument 2 secured by the one-hand fixing member 1C. The accessory body 11C can be replaced to accommodate the installation of different surgical instruments 2. That is, according to different implementations of the surgical instrument 2 , the different accessory bodies 11C, 11D, and 11E are connected to the connecting rod 1213 through the second connecting unit 1212 and the second movable member 1232 , respectively.

[0096] like Figure 13The figure shows an overall schematic diagram of a one-handed fixing part 1F provided by the present invention. The one-handed fixing part 1F is only suitable for a laser 23. That is, the laser 23 is fixedly mounted on a matching main body 3 through the one-handed fixing part 1F. Different from the above-mentioned embodiment, the one-handed fixing part 1F includes an accessory main body 11F and a fixing member 12F and an instrument port 13F. The accessory main body 11F is a double-layer coaxial ring fixed to one side of the outer sleeve. The fixing member 12F is used to achieve multi-angle rotation to adjust the direction of the accessory main body 11F in real time. Different from the above-mentioned embodiment, the fixing member 12F lacks a connecting rod 1213, so that the accessory main body 11F is closer to the outer sleeve 31, making it easier for the laser 23 to pass through the instrument port 13F to enter an instrument channel 32 connected to the front end face of the matching main body 3.

[0097] like Figure 14 Figure 1 shows an overall schematic diagram of a one-handed fixing device 1G provided by the present invention. This one-handed fixing device 1G is adaptable to surgical instruments 2 of various diameters. Specifically, when the surgical instrument 2 is implemented as a biopsy forceps 21, a stone removal net 22, or a laser 23, the surgical instrument 2 can be secured to a matching body 3 via this one-handed fixing device 1G. In other words, the diameter of this one-handed fixing device 1G is adjustable.

[0098] Specifically, the one-handed fixing device 1G includes an accessory body 11G, a fixing member 12G, and an instrument opening 13G. The accessory body 11G is mounted on the outer sleeve 31 through the fixing member 12G, and the instrument opening 13G is provided on the accessory body 11G.

[0099] It is worth mentioning that the radial length of the accessory body 11 is adjustable, and the one-handed fixing member 1G includes an adjusting member 15G, which is provided at the side end of the accessory body 11G to adjustably control the radial size of the instrument opening 13. The instrument opening 13 allows a surgical instrument 2 to pass through.

[0100] The fixing member 12G includes a connecting assembly 121G, a fixing member 122, and a movable assembly 123G. The connecting assembly 121G is movably connected to the fixing member 122 via the movable assembly 123G, and the fixing member 122 is fixed to the supporting body 3. Unlike the previous embodiment, the connecting assembly 121G lacks a connecting rod. This allows the extension channel of the instrument port 13 to be parallel to an instrument channel 32 of the supporting body 3 when the accessory body 11 is mounted on the supporting body 3 via the fixing member 12. This allows the surgical instrument 2 to be closer to the supporting body 3 when mounted on the one-handed fixing member 1G, facilitating single-handed operation by the operator.
