Abstract
Description
Technical Field
[0001] This invention relates to the field of ophthalmic medical devices, specifically to a pressure balloon capable of precise pressure positioning and control. Background Technology
[0002] Rhegmatogenous retinal detachment is a serious blinding eye disease, but timely surgical treatment can save the patient's vision. Currently, surgical methods are divided into internal and external approaches depending on the approach. Internal vitrectomy is relatively mature, but it also has the following disadvantages: firstly, because it alters the oxygen concentration distribution within the eye, the surgery can easily lead to the formation and development of cataracts; secondly, postoperative retinal retinal attachment requires extremely strict patient positioning. Furthermore, as an invasive procedure, this surgery carries risks such as infection, endophthalmitis, and iatrogenic retinal tears. Compared to the internal approach, the external approach, due to its less interference with intraocular structures, is particularly suitable for patients with relatively simple peripheral retinal tears and younger patients.
[0003] Currently, the most classic surgical procedures are scleral ligation and scleral buckling. The former is mainly for multiple or scattered eye tears, using a silicone band to apply pressure to the eyeball to close the tears, but it also has drawbacks such as affecting the shape and refractive state of the eyeball. The latter uses a solid silicone block or a pressure balloon as a local pressure agent. After precise positioning and cryotherapy, pressure is applied to the corresponding point on the outside of the eyeball to achieve surgical goals such as closing the eye tears and relieving vitreous traction.
[0004] In clinical practice, we have observed several shortcomings in existing pressure balloons, including: 1. The balloon's cylindrical or elongated ellipsoidal shape causes it to rotate and shift after implantation due to eye movement and friction with surrounding tissues, affecting precise positioning and reducing surgical success rates; 2. The outer contact surface protrudes beyond the conjunctival surface after media filling, resulting in significant foreign body sensation and poor comfort for postoperative patients; 3. During blinking, the pressure balloon may bounce on the ocular surface due to external force, causing transient excessive or insufficient pressure, leading to intraocular pressure fluctuations and vitreous traction; 4. In the later stages of treatment, because the retinal tear has closed, traditional pressure balloons, when punctured or removed, lack a slow release process to reduce pressure, which also affects retinal reattachment effectiveness to some extent.
[0005] Therefore, in summary, current pressure balloons have the following unresolved issues: 1. During balloon implantation, it is difficult to accurately fix the balloon at the retinal detachment location, resulting in inaccurate pressure placement. 2. The pressure applied by the balloon does not fully act on the retinal detachment site, leading to poor pressure application. 3. Postoperative eye movements can affect the balloon position, thus impacting the pressure application effect.
[0006] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention
[0007] To address the aforementioned technical challenges, we propose a pressure balloon that allows for precise positioning and pressure control. During operation, doctors can not only precisely position the balloon for pressure application but also accurately control the pressure exerted by the balloon on the eyeball.
[0008] To achieve the above objectives, the technical solution of the present invention is as follows:
[0009] A pressure balloon capable of precise pressure positioning and application includes a support member, a balloon, a drainage tube, and a drainage valve. The support member is made of a rigid, tensile-strength polymer material, and the balloon is made of a soft polymer material. A through-hole extends through the center of the upper surface of the support member, and the drainage valve is connected to the center of the lower surface of the balloon. The inner end of the drainage tube extends through the through-hole of the support member, with the inner end of the tube protruding from the center of the upper surface of the support member and contacting the drainage valve. The balloon is positioned above the center of the support member, clamping the drainage valve between the lower surface of the balloon and the upper surface of the support member. When the front section of the drainage tube moves inward along the through-hole of the support member, the inner end of the drainage tube can open the drainage valve. The rear end of the drainage tube is exposed outside the support member.
[0010] Preferably, the drainage valve includes a resilient valve seat, a connector, and a resilient fixing pin. The connector is disposed in the middle of the bottom surface of the resilient valve seat. The resilient valve seat is fixed to the middle of the lower surface of the balloon by two resilient fixing pins on both sides, and the connector is positioned close to the through hole opening in the middle of the upper surface of the support. The resilient valve seat blocks the space between the balloon opening and the through hole of the support, and can push the resilient valve seat upward when the inner end of the drainage tube moves inward through the connector.
[0011] Preferably, a tee tube is connected to the outer end of the drainage tube. The tee tube includes a main tube, an inlet tube, and a pressure measuring tube that are connected and interconnected at one end.
[0012] Preferably, the support member has a triangular structure. After locating the position requiring compression during balloon placement, the balloon's center of gravity is aligned with the compression point, and the balloon is then sutured and fixed. The through hole is located on the side of the support member, near one of its corners.
[0013] Preferably, the connector is made of elastic polymer material, and when the inner tube head of the drainage tube presses against the bottom of the connector, the elastic valve seat is pushed upward. When the inner tube head of the drainage tube is pulled out from the bottom of the connector, the elastic valve seat rebounds downward to seal the through hole in the middle of the upper surface of the support.
[0014] Preferably, the main pipe of the tee pipe is connected to the drainage pipe via a quick connector.
[0015] Through the above technical solution, the present invention comprises a support member, a balloon, a drainage tube, and a drainage valve. The support member is made of a rigid tensile-strength polymer material, and the balloon is made of a soft polymer material. A through hole extends through the middle of the upper surface of the support member, and the drainage valve is connected to the middle of the lower surface of the balloon. The inner end of the drainage tube can penetrate through the through hole of the support member, and the inner end of the drainage tube protrudes from the middle of the upper surface of the support member, and the inner end of the drainage tube contacts the drainage valve. The balloon is located in the middle of the upper part of the support member, and the drainage valve is clamped between the lower surface of the balloon and the upper surface of the support member. When the front part of the drainage tube moves inward along the through hole of the support member, the inner end of the drainage tube can push open the drainage valve. The rear end of the drainage tube is exposed outside the support member. Normally, the drainage valve seals the through-hole on the support, ensuring a sealed balloon. During balloon placement, after locating the area requiring pressure, the center of gravity of the balloon's triangular shape is aligned with the pressure point, and then three-point sutures are used for fixation. Applying pressure to the balloon at this point allows for precise application to the affected area, preventing displacement. If pressure adjustments are needed during or after balloon placement, the surgeon simply uses a drainage tube. This tube is inserted into the through-hole of the support, and the drainage valve is opened, allowing communication between the balloon and the outside. Pure fluid or partial fluid release is then injected into the balloon through the drainage tube. The drainage tube can also be connected to a pressure monitoring device to monitor the internal pressure. This provides the following benefits: 1. The surgeon can precisely control the balloon's pressure application position. The triangular shape of the balloon, aligned with the pressure point, allows for precise pressure control. 2. During surgery and follow-up, the balloon's pressure on the eyeball can be precisely controlled, ensuring appropriate pressure and improving the effectiveness of the pressure application. 3. Rigid support can restrict the direction of balloon expansion, allowing for targeted pressure on the patient without outward protrusion. The patient's eye movements do not affect the position and pressure of the balloon on the eyeball, and reduce the patient's postoperative foreign body sensation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.
[0026] Example
[0027] like Figure 1-5 As shown, a pressure balloon capable of precise pressure positioning and control includes a support 1, a balloon 2, a drainage tube 3, and a drainage valve 4. The support 1 is made of a rigid tensile polymer material, and the balloon 2 is made of a soft polymer material. A through hole 5 extends through the middle of the upper surface of the support 1, and the drainage valve 4 is connected to the middle of the lower surface of the balloon 2. The inner end of the drainage tube 3 can penetrate into the through hole 5 of the support 1, with the inner end of the drainage tube 3 protruding from the middle of the upper surface of the support 1 and contacting the drainage valve. The balloon 2 is positioned above the middle of the support 1, clamping the drainage valve 4 between the lower surface of the balloon 2 and the upper surface of the support 1. When the front section of the drainage tube 4 moves inward along the through hole 5 of the support 1, the inner end of the drainage tube 3 can push open the drainage valve 4. The rear end of the drainage tube 3 is exposed outside the support 1.
[0028] The drainage valve 4 includes an elastic valve seat 41, a connector 42, and an elastic fixing pin 6. The connector 42 is located in the middle of the bottom surface of the elastic valve seat 41. The elastic valve seat 41 is fixed to the middle of the lower surface of the balloon 2 by two elastic fixing pins 6 on both sides, and the connector 42 is close to the through hole 5 in the middle of the upper surface of the support member 1. The elastic valve seat blocks the space between the balloon opening and the through hole of the support member, and can push the elastic valve seat upward when the inner end of the drainage tube moves inward through the connector.
[0029] Simultaneously, a three-way connector 7 is connected to the outer end of the drainage tube 3. The three-way connector 7 includes a main tube 71 connected at one end and interconnected with each other, an inlet tube 72, and a pressure measuring tube 73. The inlet tube 72 can be connected to an external infusion device to inject fluid into the balloon 2, while the pressure measuring tube 73 can be connected to an external pressure measuring device to monitor the pressure inside the balloon 2 in real time. The main tube 71 of the three-way connector 7 is vertically connected to the drainage tube 3 to facilitate external connection to external infusion devices and external pressure measuring devices from the side. The main tube 71 of the three-way connector 7 and the drainage tube 3 are connected via a quick connector 8, allowing the doctor to quickly connect the two during the procedure.
[0030] To facilitate the insertion of the drainage tube 4 and fix the support member 1, the support member 1 has a triangular structure, and the through hole 5 is located on the side of the support member 1 near one of the corners of the support member 1.
[0031] In addition, the connector 42 is made of elastic polymer material, and when the inner tube head of the drainage tube 3 presses against the bottom of the connector 42, the elastic valve seat 41 is pushed upward. When the inner tube head of the drainage tube 3 is pulled out from the bottom of the connector 42, the elastic valve seat 41 rebounds downward to seal the through hole in the middle of the upper surface of the support member 1.
[0032] The support component 1 is a sheet of high-strength polymer material or silicone sheet with tensile strength. The drainage valve 4 is essentially a valve fixed at both ends, used to open and close the orifice 5 on the support component. The drainage tube 3 acts as a connecting channel; when inserted to the innermost part of the support component 1, it can open the drainage valve 4, opening the outside world and the inside of the balloon 2. This connecting channel, the drainage tube 3, has some rigidity; when it is inserted to the innermost part of the support component 1, it can contact the middle of the drainage valve 4, which is a protruding structure that can push the drainage valve 4 upwards. This opens the channel from the drainage tube 3 to the balloon 2, allowing the fluid in the drainage tube 3 to enter the balloon 2.
[0033] Normally, the drainage valve 4 seals the hole in the balloon 2, achieving a sealed state. When operation is needed, the drainage tube 3 is used to add or partially release liquid. After the drainage tube 3 opens the drainage valve 4, the pressure measuring tube 73 can also be connected to the pressure detection device to detect the internal pressure of the balloon 2, so as to achieve precise control and pressurization.
[0034] In this example, the present invention comprises a support member 1, a balloon 2, a drainage tube 3, and a drainage valve 4. The support member 1 is made of a rigid tensile polymer material, and the balloon 2 is made of a soft polymer material. A through hole 5 extends through the middle of the upper surface of the support member 1, and the drainage valve 4 is connected to the middle of the lower surface of the balloon 2. The inner end of the drainage tube 3 can penetrate into the through hole 5 of the support member 1, and the inner end of the drainage tube 3 protrudes from the middle of the upper surface of the support member 1, and the inner end of the drainage tube 3 contacts the drainage valve 4. The balloon 2 is located in the middle of the upper part of the support member 1, and the drainage valve 4 is clamped between the lower surface of the balloon 2 and the upper surface of the support member 1. When the front part of the drainage tube 3 moves inward along the through hole 5 of the support member 1, the inner end of the drainage tube 3 can push open the drainage valve 4. The rear end of the drainage tube 3 is exposed outside the support member 1. Normally, the drainage valve 4 seals the through-hole on the support 1, achieving a sealed state for the balloon 2. When operation is needed, the doctor uses the drainage tube 3, inserting it into the through-hole 5 of the support 1, and then opening the drainage valve 4 to connect the inside of the balloon 2 with the outside. Pure liquid or partially released liquid is then injected into the balloon 2 through the drainage tube 3. After the drainage tube 3 opens the balloon 2, it can also connect to a pressure detection device to monitor the internal pressure of the balloon 2. This allows the doctor to precisely control the balloon's pressure application position during operation. The balloon's overall triangular center of gravity is aligned with the pressure point, and it is then fixed with three-point sutures, enabling precise pressure control for the patient. Simultaneously, during surgery and subsequent patient follow-up, the pressure exerted by the balloon on the eyeball can be precisely controlled to maintain appropriate pressure and improve the pressure application effect. Furthermore, the rigid support restricts the balloon's expansion direction, allowing for targeted pressure application to the patient, preventing outward protrusion. Eye movements do not affect the balloon's pressure application position and reduce postoperative foreign body sensation. It achieved the goal of novel design, reasonable structure, and good application effect.
[0035] The above description is merely a preferred embodiment of the compression balloon of the present invention, which can accurately control the compression position and pressure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
