Description

Technical Field

[0001] The invention belongs to the technical field of medical waste liquid recovery, and in particular relates to an ophthalmic surgery fluid collection box. Background Art

[0002] Ophthalmic surgery is an important means of treating ophthalmic diseases. For example, ophthalmic phacoemulsification is currently the most advanced cataract treatment technology. Phacoemulsification can remove cataracts through an incision with a chord length of less than 3 mm, and implant a foldable intraocular lens through this small incision. However, during the operation, the control of fluid accumulation has always been a problem that troubles doctors. Most traditional ophthalmic surgical injection and suction tubes are integrated with the surgical fluid accumulation box and phacoemulsification handle. The fluid accumulation control method has certain limitations, such as complex operation, poor stability, low safety, and difficulty in accurately controlling the negative pressure flow. Although there are surgical effusion boxes in the prior art as independent structures for safe disposable use, such as the negative pressure effusion box device for ophthalmic phacoemulsification disclosed in Chinese patent CN110368533B, although the reaction speed is improved by negative pressure control, the patent scheme can only generate a vacuum through the mutual squeezing of a peristaltic pump and a silicone skin to generate power to draw out the cataract residues after the phacoemulsification handle is crushed. Since the negative pressure sensor is only matched with the peristaltic pump, this type of effusion box cannot be directly used for gravity dripping, and therefore, the convenience of use is insufficient. Summary of the invention

[0022] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] An ophthalmic surgery fluid collection box, such as Figures 1 to 5 As shown, it includes a shell structure consisting of a front shell 1 and a rear shell 2, and a liquid accumulation cavity is formed between the front shell and the rear shell; a liquid inlet pipe 3, an infusion pipe 4 and a suction pipe 5 are provided on the side plate 11 of the front shell, and a negative pressure regulating device and two groups of liquid inlet control components are provided on the panel 6 of the front shell. The negative pressure regulating device includes a silicone sheet 13 embedded in the front shell through a groove, and the silicone sheet is a detachable installation form, so the silicone sheet can be mass-produced and assembled on the front shell, which reduces the production cost. Each liquid inlet control component includes a flow regulating valve 7 and a negative pressure sensor 8, and a negative pressure sensor cover 9 is provided on the side of the negative pressure sensor facing the liquid accumulation cavity; a waste liquid bag 10 is detachably installed on the outer side of the panel of the rear shell, and a plurality of waste liquid ports 12 connected to the waste liquid bag are provided on the panel of the rear shell.

[0025] Typically, the middle of the silicone sheet has an inner concave portion that is sunken toward the side of the effusion chamber, so that it can be moved toward the side of the effusion chamber (recessed) or away from the side of the effusion chamber (convexed). Specifically, a mounting groove 15 is provided on the panel of the front shell, and the silicone sheet is installed in the mounting groove. Several guide grooves 16 are provided at the bottom of the groove, and liquid holes 17 that are connected to the effusion chamber are provided at both ends of the guide groove. A silicone sheet deformation accommodation space 18 is provided in the middle of the mounting groove, allowing the middle of the silicone sheet to squeeze into the accommodation space, increasing the displacement amplitude of the silicone sheet within the limited (thickness) space of the effusion box, which is more conducive to the establishment of negative pressure. In addition, a fixing groove is provided on the side wall of the mounting groove, and the fixing groove is used for the installation of the silicone sheet. Since the edge of the silicone sheet is pressed into the fixing groove, it not only ensures the stability of the structure, but also ensures the sealing. Such a structural design allows the silicone sheet to be mass-produced separately, rather than being integrally formed with the front shell of the effusion box, thereby reducing the production cost.

[0026] A plurality of connecting channels 19 are provided on the inner wall of the panel of the front shell, and each connecting channel connects the two guide grooves that are farthest apart. Each connecting channel is formed between two corresponding ribs. In addition, an auxiliary rib corresponding to the connecting channel is provided on the inner wall of the panel of the rear shell, that is, when the front shell and the rear shell are buckled and fixed, the auxiliary rib fits with the rib forming the connecting channel, and a complete channel is formed inside, and a stable support is formed between the auxiliary rib and the rib of the connecting channel, ensuring that the effusion box has high structural strength and good stability.

[0027] It should be pointed out that one set of liquid inlet control components is a commonly used option, and the negative pressure sensor included in it is directly linked to the surgical instrument, that is, it matches the liquid flow rate generated by the roller squeezing on the surgical instrument as the driving force, while the other set of liquid inlet control components is a backup option. When gravity dripping is required, it is only necessary to turn off the commonly used liquid inlet control component (negative pressure sensor) and make the backup liquid inlet control component work, so as to match the liquid inlet speed during gravity dripping. It is simple and convenient to use, and ensures the accurate and stable negative pressure.

[0028] The flow regulating valve adopts a rotation-controlled flow regulating valve, which is very convenient for controlling the liquid inlet speed. The front shell and the rear shell are both made of ABS material, which has good biocompatibility and corrosion resistance. The negative pressure regulating device realizes precise control of the negative pressure flow by pressing the silicone pad and rotating the flow regulating valve to ensure safety during the operation. The waste liquid bag is used to collect the effusion generated during the operation to avoid surgical field contamination. At the same time, the waste liquid bag can be detachably installed on the rear shell and has the characteristics of disposable use. In an optional embodiment, a card slot 15 is provided on the panel 14 of the rear shell, and a card block matching the card slot is provided on the waste liquid bag. In another optional embodiment, the waste liquid bag is glued to the panel of the rear shell. Of course, those skilled in the art can also fix the waste liquid bag in other ways, as long as the waste liquid bag can be conveniently installed on the rear shell and can be conveniently disassembled as needed.

[0029] The ophthalmic surgical fluid collection box provided by the invention can be applied to both gravity and main control modes, and only the corresponding liquid inlet control components need to be turned on. Specifically, one group of liquid inlet control components of the fluid collection box matches the roller extrusion on the surgical instrument as the driving force, while the other group of liquid inlet control components matches the liquid collection method of gravity dripping. The flow regulating valve is used to adjust the negative pressure and flow rate to stabilize the patient's anterior chamber fluid, monitor the pressure changes in the box body, and ensure the stability of the anterior chamber during surgery. Usually, the liquid inlet tube, perfusion tube and suction tube are all arranged on the side panel on the same side of the front shell. The two groups of liquid inlet control components are symmetrically arranged on the panel of the front shell. The front shell and the rear shell are fixed by ultrasonic welding. Three through holes are provided on the side panel of the front shell, and the liquid inlet tube, perfusion tube and suction tube are respectively inserted into one of the through holes and fixed by ultrasonic welding.

[0030] Working principle: During the operation, the roller on the surgical instrument can be used to squeeze the silicone sheet on the effusion box to provide negative pressure for the ophthalmic surgical effusion box. The negative pressure sensor that matches the roller extrusion of the surgical instrument as the driving force monitors the negative pressure in real time and transmits the data to the surgical instrument. The negative pressure value can be adjusted according to the surgical requirements based on the negative pressure regulating device to keep it within an appropriate range. According to the actual situation, when it is necessary to work by gravity dripping, another spare negative pressure sensor is used to work to adapt to the working mode of gravity drip flow rate. There is no need to replace or adjust it again. One-click switching to the spare liquid inlet control component can achieve matching. The effusion during the operation is collected through the waste liquid bag for easy postoperative processing. In addition, the effusion box has good sealing properties, which effectively prevents external microbial contamination.

[0031] The ophthalmic surgical effusion box provided by the invention has a liquid inlet tube, an infusion tube and a suction tube arranged along the length direction of the effusion box, which saves space and is convenient for pipe laying, and can avoid deformation of the pipes at the connection to affect the flow of liquid to the greatest extent, greatly reducing the difficulty of operation for doctors and improving the efficiency of surgery. It has the characteristics of disposable use, safety and no infection, convenient postoperative treatment, and is conducive to the classification and recycling of clinical waste. The effusion box has high reliability and better safety, and the anterior chamber is stable during surgery; the negative pressure control is convenient and accurate, the rise is fast, and the release is rapid. The silicone is easy to install without welding and fixing, and it is simple and convenient to use with low cost.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
