Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an integrated curved cystoscope. Background Technique

[0002] The cystoscope is a commonly used endoscopic device in urological surgery, mainly used for examining and treating bladder diseases. With the development of technology, the integrated curved cystoscope has gradually become the mainstream product. However, the existing devices still have certain limitations, such as insufficient flexibility, poor durability, and room for improvement in imaging quality. Therefore, it is of great significance to improve the integrated curved cystoscope.

[0003] The prior art document with the publication number of CN219516221U provides an integrated curved cystoscope. In the related technology of this device, the urethra of the patient is directly dilated by using the curved part, and then it enters the predetermined lesion of the patient. At the same time, it is beneficial for patients with urethral stricture to undergo surgery, and the sheath is integrated, reducing the requirements for medical staff's clinical experience and the surgical process. At the same time, it can be operated with one hand, greatly simplifying the operation of the surgery.

[0004] Although the above prior art solution can achieve the related beneficial effects through the structure of the prior art, it still has the following defects: the curved part of the device is bent at a predetermined angle and cannot be subjectively bent for use. Therefore, the effect of the extension part inserted into the patient's urethra for bending use is not good.

[0005] In view of this, we propose an integrated curved cystoscope. Content of the Utility Model

[0006] In order to improve the problems proposed in the above background technique, the utility model provides an integrated curved cystoscope.

[0007] The integrated curved cystoscope provided by the utility model adopts the following technical solutions:

[0008] An integrated curved cystoscope, comprising:

[0009] A detachable sheath;

[0010] A lens body, fixedly connected to one end of the detachable sheath to form an integrated curved cystoscope;

[0011] A probe with a curved groove, fixedly installed at one end of the lens body through a bolt meeting medical requirements;

[0012] A silicone airbag, fixedly connected inside the probe with a curved groove;

[0013] An air intake pipe is fixedly installed at one end joint of the silicone airbag, passes through the lens body and the detachable lens sheath, and is fixedly connected with an extension pipe.

[0014] An air cylinder filled with sterile gas is fixedly connected to the other end of the extension pipe.

[0015] By adopting the above technical solution, the air cylinder transfers gas into the air intake pipe through the extension pipe, thereby expanding the silicone airbag into which the air intake pipe converges. The expanded silicone airbag adjusts the angle of the probe with a bending groove, enabling the integrated curved cystoscope to freely adjust the angle within the patient's urethra for insertion and detection, thus improving the flexibility of the device.

[0016] As an alternative solution of the technical solution of this utility model document, a ring groove is formed on the outside of the lens body relative to the bolt installation position, and an alloy ring meeting medical requirements is elastically clamped and installed in the ring groove.

[0017] By adopting the above technical solution, the alloy ring covers and protects the installation hole of the installation bolt, thereby preventing cell tissue residues at the installation hole of the installation bolt and causing bacterial growth.

[0018] As an alternative solution of the technical solution of this utility model document, a medical alloy insertion column meeting medical requirements is fixedly connected to one side of the probe equipped with a visual unit. The insertion column is inserted and matched with the lens body and fixed by bolt connection, and the probe is a column made of medical silicone material.

[0019] By adopting the above technical solution, the probe is inserted and installed between the alloy insertion column and the lens body, making the installation and replacement of the probe simple. Moreover, the probe made of silicone material has elastic characteristics, thus avoiding damage to the pipeline during insertion into the urethra and ensuring the safety of the device during insertion and detection.

[0020] As an alternative solution of the technical solution of this utility model document, alloy positioning cylinders meeting medical requirements are fixedly connected to a plurality of operation holes with different specifications formed in the probe.

[0021] By adopting the above technical solution, the alloy positioning cylinders can add fixed positioning between the probe inserted and installed through the alloy insertion column and the lens body, thereby ensuring the stability of the probe during installation and use.

[0022] As an alternative solution of the technical solution of this utility model document, the air cylinder includes a piston cylinder filled with sterile gas. A piston push rod that is slidably matched with it is slidably connected in the piston cylinder, and a spring member is sleeved outside the piston push rod.

[0023] By adopting the above technical solution, the transfer of sterile gas is achieved by utilizing the limiting pressure of the piston push rod in the piston cylinder, so that the transferred gas fills and expands the silicone airbag, thereby realizing the angle bending control of the probe. Moreover, the piston push rod can keep the probe in a horizontal state under the elastic limitation of the external spring part, which is convenient for flexible angle tilt adjustment.

[0024] In summary, the present invention includes at least one of the following beneficial technical effects:

[0025] 1. The utility model utilizes a gas cylinder to transfer gas into the airway tube through an extension tube, thereby inflating a silicone balloon introduced through the airway tube, so that the inflated silicone balloon adjusts the angle of the probe with a bending groove, thereby forming an integrated curved cystoscope that can be freely adjusted in the patient's urethra for insertion detection, thereby improving the flexibility of the device.

[0026] 2. The utility model utilizes the alloy plug-in column and the mirror body for plug-in installation, so that the probe can be easily installed and replaced. The probe is made of silicone material, which makes it elastic, thereby avoiding damage to the pipeline when inserted into the urethra, and ensuring the safety of the device for insertion detection.

[0033] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification.

[0034] Referring to Figure 1 and Figure 2 In the integrated curved cystoscope described in the embodiment of the present utility model, the lens body 2 is fixedly connected to one end of the detachable sheath 1 to form an integrated curved cystoscope;

[0035] The probe 3 provided with a bending groove is fixedly installed at one end of the lens body 2 through bolts meeting medical requirements;

[0036] The silica gel airbag 4 is fixedly connected inside the probe 3 provided with a bending groove;

[0037] The air guide tube 5 is fixedly installed at the joint at one end of the silica gel airbag 4, and penetrates through the lens body 2 and the detachable sheath 1 and is fixedly connected with an extension tube 6;

[0038] The air cylinder member 7 filled with sterile gas inside is fixedly connected to the other end of the extension tube 6.

[0039] For this integrated curved cystoscope, by using the air cylinder member 7 to transfer gas into the air guide tube 5 through the extension tube 6, the silica gel airbag 4 into which the gas flows through the air guide tube 5 is inflated, so that the inflated silica gel airbag 4 adjusts the angle of bending of the probe 3 provided with a bending groove, enabling the formed integrated curved cystoscope to freely adjust the angle inside the patient's urethra for insertion detection, thereby improving the flexibility of the device in use.

[0040] Referring to Figure 3 and Figure 1 In the integrated curved cystoscope described in the embodiment of the present utility model, there is a ring groove 21 starting from the outside of the lens body 2 relative to the bolt installation position, and an alloy ring 22 meeting medical requirements is elastically clamped and installed in the ring groove 21.

[0041] For this integrated curved cystoscope, by using the alloy ring 22 to cover and protect the installation holes of the installation bolts, the residual cell tissues at the installation holes of the installation bolts are avoided, preventing the growth of bacteria.

[0042] Referring to Figure 4 and Figure 1 In the integrated curved cystoscope described in the embodiment of the present utility model, on one side of the probe 3 equipped with a visual unit, there is a alloy insertion column 31 meeting medical requirements fixedly connected. The insertion column 31 is in insertion fit with the lens body 2 and is fixedly connected by bolts. Moreover, the probe 3 is a column made of medical silica gel material, and alloy positioning cylinders 32 meeting medical requirements are fixedly connected in a plurality of operation holes with different specifications opened inside the probe 3.

[0043] The integrated curved cystoscope is installed by inserting the alloy insertion post 31 into the mirror body 2, which makes the probe 3 easy to install and replace. The probe 3 made of silica gel material has elastic characteristics, thus avoiding damage to the pipeline during insertion into the urethra and ensuring the safety of the device during insertion and detection. The alloy positioning cylinder 32 can be used to fix and position the probe 3 inserted and installed through the alloy insertion post 31 between the probe 3 and the mirror body 2, thus ensuring the stability of the probe 3 during installation and use.

[0044] Referring to Figure 5 and Figure 1 , in the integrated curved cystoscope described in the embodiment of the present invention, the air cylinder member 7 includes a piston cylinder 71 filled with sterile gas inside, a piston push rod 72 slidably connected to the piston cylinder 71 and slidably adapted to it, and a spring member 73 sleeved outside the piston push rod 72.

[0045] In the integrated curved cystoscope, by limiting and pressing the piston push rod 72 in the piston cylinder 71, the transfer of sterile gas is realized, so that the transferred gas fills and expands the silica gel airbag 4, realizing the angle bending control of the probe 3. And under the elastic limit of the external spring member 73, the piston push rod 72 can keep the probe 3 in a horizontal state, facilitating flexible angle inclination adjustment.

[0046] Working principle: When the mirror body 2 needs to be bent and adjusted during insertion into the patient's urethra, the operating column presses the piston push rod 72 in the air cylinder member 7. As the piston push rod 72 drives the spring member 73 to be continuously compressed, the sterile gas filled in the piston cylinder 71 flows through the extension tube 6 and into the silica gel airbag 4 along the air guide tube 5, inflating the silica gel airbag 4;

[0047] At this time, the inflated silica gel airbag 4 drives the probe 3 provided with a bending groove to be limited and bent, so that the mirror body 2 is guided and inserted under the guidance of the bent silica gel material probe 3.
