[0002] Cystoscopic injection needles are used for injections into the urethra, bladder neck, and bladder wall via a cystoscope. The multi-point injection function means that multiple injections can be performed simultaneously in one procedure.
[0003] The existing cystoscopic injection needles for simultaneous multi-point injection are prone to shaking when the medication is injected into the bladder using a cystoscope to check the injection, which reduces the stability of the injection needle. At the same time, the device cannot disinfect or protect the needle during use, which could lead to accidental injury to medical staff when preparing the needle before the operation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a cystoscope injection needle for simultaneous multi-point injection, which has the advantages of clamping and fixing the needle body and disinfecting and protecting the multi-point needle tips, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a cystoscope injection needle for simultaneous multi-point injection, comprising a needle body, a scope body slidably sleeved on the outer wall of the needle body, a handle fixedly installed on the outer wall of the scope body, a fixing plate fixedly installed on the top of the handle, a cylinder fixedly installed on the top of the handle, a pull rod slidably sleeved on the inner wall of the cylinder, a needle tip fixedly installed on the bottom of the needle body, a locking block fixedly connected to the outer wall of the needle body, a protective sleeve installed on the outer wall of the locking block, a disinfection lamp fixedly installed on the inner wall of the protective sleeve, a first spring on the bottom inner wall of the protective sleeve, a circular plate fixedly installed at one end of the first spring, a second spring movably sleeved on the outer wall of the pull rod, a short rod fixedly installed on the outer wall of the pull rod, a clamping plate fixedly connected to the outer wall of the short rod, a connector fixedly installed on the outer wall of the scope body, a slot formed on the inner wall of the protective sleeve, and a switch fixedly installed on the outer wall of the protective sleeve.
[0006] As a preferred embodiment of this utility model: a push rod is slidably connected to the inner wall of the needle body, and a piston is fixedly installed at the bottom of the push rod.
[0007] As a preferred technical solution of this utility model: the inner wall of the protective sleeve is provided with a sliding groove, and the outer wall of the sliding groove is adapted to the outer wall of the card block.
[0008] As a preferred technical solution of this utility model: the switch and the disinfection lamp are electrically connected, and the outer wall of the circular plate and the inner wall of the protective sleeve are slidably connected.
[0009] As a preferred technical solution of this utility model: the outer walls of the clamping plate and the fixing plate are semi-arc-shaped, and the clamping plate and the fixing plate are symmetrically arranged with the needle body as the center.
[0010] As a preferred technical solution of this utility model: one end of the second spring is fixed to the outer wall of the push rod, and the other end of the second spring is fixed to the inner wall of the cylinder.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This cystoscope injection needle, capable of simultaneous multi-point injection, works by pulling a lever with external force. The lever causes a short rod to compress a second spring, allowing the short rod to slide along the inner wall of the cylinder. The clamping plate disengages from the outer wall of the needle body, allowing the operator to adjust the needle length according to their position for injection. Releasing the lever with external force causes the second spring to push the short rod, bringing the clamping plate into contact with the outer wall of the needle body for clamping. The endoscope is then used to examine the needle, preventing it from shaking and reducing its stability.
[0013] 2. This cystoscope injection needle for simultaneous multi-point injection utilizes the needle body to drive the locking block to slide through the groove to the top of the circular plate. With the needle tip at the top of the circular plate, external force causes the needle body to compress the first spring, which in turn causes the locking block to rotate on the inner wall of the protective sleeve. When the external force releases the protective sleeve, the first spring 12 is released elastically, and the circular plate pushes the locking block to engage with the locking groove, thus achieving installation. The control switch is used, and the needle tip is disinfected and sterilized using a disinfection lamp, improving the equipment's protective performance. Attached Figure Description

[0021] Please see Figure 1 - Figure 5 A cystoscope injection needle for simultaneous multi-point injection includes a needle body 1, a scope body 2 slidably sleeved on the outer wall of the needle body 1, a handle 5 fixedly installed on the outer wall of the scope body 2, a fixing plate 6 fixedly installed on the top of the handle 5, a cylinder 8 fixedly installed on the top of the handle 5, a pull rod 9 slidably sleeved on the inner wall of the cylinder 8, a needle tip 14 fixedly installed on the bottom of the needle body 1, a locking block 13 fixedly connected to the outer wall of the needle body 1, a protective sleeve 3 installed on the outer wall of the locking block 13, a disinfection lamp 16 fixedly installed on the inner wall of the protective sleeve 3, a first spring 12 on the bottom inner wall of the protective sleeve 3, a circular plate 21 fixedly installed at one end of the first spring 12, a second spring 17 movably sleeved on the outer wall of the pull rod 9, a short rod 20 fixedly installed on the outer wall of the pull rod 9, a clamping plate 7 fixedly connected to the outer wall of the short rod 20, a connector 11 fixedly installed on the outer wall of the scope body 2, a slot 18 opened on the inner wall of the protective sleeve 3, and a switch 4 fixedly installed on the outer wall of the protective sleeve 3.
[0022] In the above structure, by installing the needle 14, which has multiple needle tips, multiple injection sites can be injected simultaneously. During surgery, it is necessary to inject drugs into the upper, lower, left and right branching points of the bladder neck, thereby improving injection efficiency.
[0023] In a preferred embodiment, a push rod 10 is slidably connected to the inner wall of the needle body 1, and a piston 19 is fixedly installed at the bottom of the push rod 10.
[0024] In the above structure, a piston 19 is fixedly installed at the bottom of the push rod 10. The push rod 10 drives the piston 19 to push the drug on the inner wall of the needle body 1, so that the person can inject the drug during use.
[0025] In a preferred embodiment, the inner wall of the protective sleeve 3 is provided with a groove 15, and the outer wall of the groove 15 is adapted to the outer wall of the locking block 13.
[0026] In the above structure, the outer wall of the slide groove 15 is adapted to the outer wall of the locking block 13. The needle body 1 drives the locking block 13 to slide through the slide groove 15 to the top of the circular plate 21. The external force rotates the protective sleeve 3, which drives the locking groove 18 to engage with the locking block 13.
[0027] In a preferred embodiment: the switch 4 is electrically connected to the disinfection lamp 16, and the outer wall of the circular plate 21 is slidably connected to the inner wall of the protective sleeve 3.
[0028] In the above structure, the needle 14 is located at the top of the circular plate 21. The external force of the needle body 1 drives the needle 14 to press against the first spring 12, so that the needle body 1 drives the locking block 13 to rotate on the inner wall of the protective sleeve 3. The external force releases the protective sleeve 3, and the first spring 12 elastically releases and pushes the locking block 13 and the locking groove 18 through the circular plate 21 to achieve installation. The control switch 4 uses the disinfection lamp 16 to disinfect and sterilize the needle 14, thereby improving the protection of the equipment.
[0029] In a preferred embodiment, the outer walls of the clamping plate 7 and the fixing plate 6 are semi-circular, and the clamping plate 7 and the fixing plate 6 are symmetrically arranged with the needle body 1 as the center.
[0030] In the above structure, the clamping plate 7 and the fixing plate 6 are symmetrically arranged around the needle body 1. The clamping plate 7 and the fixing plate 6 are used to clamp the needle body 1 in close contact, so as to avoid the needle body 1 causing the needle tip 14 to shake and reduce the stability of the needle body 1 when the personnel use the endoscope 2 to check it during injection.
[0031] In a preferred embodiment, one end of the second spring 17 is fixed to the outer wall of the push rod 10, and the other end of the second spring 17 is fixed to the inner wall of the cylinder 8.
[0032] In the above structure, by pulling the lever 9 with external force, the lever 9 drives the short rod 20 to compress the second spring 17, so that the short rod 20 slides on the inner wall of the cylinder 8, and the clamping plate 7 is separated from the outer wall of the needle body 1. The personnel can adjust the length of the needle 14 according to the position for injection. By releasing the lever 9 with external force, the elastic force of the second spring 17 pushes the short rod 20 to make the clamping plate 7 fit against the outer wall of the needle body 1 to achieve clamping.
[0033] Working principle: The needle 14 has multiple tips, allowing simultaneous injection at multiple locations. During surgery, medication needs to be injected at several points along the superior, inferior, left, and right branching pathways of the bladder neck, improving injection efficiency. Pulling the lever 9 causes the short rod 20 to compress the second spring 17, allowing the short rod 20 to slide along the inner wall of the cylinder 8. The clamp 7 detaches from the outer wall of the needle body 1, allowing the operator to adjust the length of the needle 14 for injection. Releasing the lever 9 releases the force of the second spring 17, pushing the short rod 20 to clamp the clamp 7 against the outer wall of the needle body 1. The needle body can then be examined using the endoscope 2. 1. The needle 14 is driven to shake, reducing the stability of the needle body 1. When the needle body 1 is not in use, the needle body 1 drives the locking block 13 to slide through the slide groove 15 to the top of the circular plate 21. With the needle 14 at the top of the circular plate 21, the external force of the needle body 1 drives the needle 14 to press against the first spring 12, so that the needle body 1 drives the locking block 13 to rotate on the inner wall of the protective sleeve 3. The external force releases the protective sleeve 3, and the first spring 12 elastically releases and pushes the locking block 13 to engage with the slot 18 through the circular plate 21 to achieve installation. The control switch 4 uses the disinfection lamp 16 to disinfect and sterilize the needle 14, improving the protection of the equipment.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
