Description

Technical Field

[0001] The utility model relates to the field of arthroscopic surgery, in particular to an arthroscopic irrigation device. Background Art

[0002] During arthroscopic surgery, it is necessary to continuously inject flushing fluid into the patient's joint cavity as a water medium to fill the joint cavity, maintain a certain pressure to reduce bleeding, and keep the surgical field clear. During arthroscopic surgery, not only does it require continuous infusion of flushing fluid, but it also needs to adjust the flushing fluid infusion pressure in time according to the patient's surgical situation. Only by uninterrupted flushing fluid supply and ensuring appropriate infusion pressure can the requirements of arthroscopic surgery be met and the safety of patients be guaranteed.

[0003] At present, the method of adjusting the perfusion pressure in clinical applications is mostly to manually adjust the perfusion height of the flushing fluid, and adjust the perfusion pressure of the flushing fluid by the pressure difference generated at different heights. This method not only consumes the time and energy of the staff, making it impossible for the staff to focus on the operation, but also the adjustment range of the perfusion pressure is limited, and it is impossible to achieve precise adjustment, which increases the risk of surgery. Utility Model Content

[0004] The purpose of the utility model is to provide an arthroscopic irrigation device to address the deficiencies of the prior art, so as to solve the problem that the method of adjusting the irrigation pressure of the irrigation fluid through the pressure difference generated at different heights in the prior art not only consumes the time and energy of the staff, making it impossible for the staff to concentrate on the operation, but also the adjustment range of the irrigation pressure is limited, and precise adjustment cannot be achieved, thereby increasing the risk of the operation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An arthroscopic irrigation device includes an infusion tank and an infusion tube. The infusion tube is connected to a flushing gun. The interior of the infusion tank is divided into an inflation zone and a liquid zone by a stretchable diaphragm. The diaphragm stretches to one side after being compressed. The inflation zone is connected to an air delivery mechanism, and the liquid zone is connected to the infusion tube. A liquid filling port is provided in the liquid zone, and a cover plug is provided at the liquid filling port.

[0007] Furthermore, the gas delivery mechanism includes an electric air pump, which is connected to the inflation area through an air delivery pipe.

[0008] Furthermore, the infusion tube is provided with an infusion regulator for adjusting the flow rate of the flushing liquid.

[0009] Furthermore, the infusion tank is made of transparent material.

[0010] Furthermore, scale marks are provided on the outer side of the liquid area.

[0011] Furthermore, a liquid level alarm is provided outside the liquid area.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with an infusion tank which is internally divided into an inflation zone and a liquid zone by a diaphragm. The inflation zone is inflated and pressurized or air is pumped and decompressed through a gas transmission mechanism to achieve the effect of increasing or decreasing the perfusion pressure of the flushing liquid. There is no need to frequently move the height of the flushing liquid, which saves time and effort, and can expand the adjustment range of the perfusion pressure to meet the requirements of arthroscopic surgery, accurately adjust the perfusion pressure of the flushing liquid, and minimize the surgical risks.

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0020] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0022] For easier understanding, see Figure 1 and Figure 2 This embodiment provides an arthroscopic irrigation device, including an infusion tank 1, the interior of the infusion tank 1 is divided into an inflation zone 3 and a liquid zone 4 by a stretchable diaphragm 2, the inflation zone 3 is connected to the gas delivery mechanism, the gas delivery mechanism is used to deliver air to the inflation zone 3, the liquid zone 4 for storing the flushing liquid is connected to the infusion tube 5, the infusion tube 5 is connected to the flushing gun to deliver the flushing liquid, and a liquid filling port is opened above the liquid zone 4, and a cover plug 6 is provided at the liquid filling port. Since the diaphragm 2 is stretchable, during the surgical preparation process, the staff continuously adds flushing liquid to the liquid zone 4 of the infusion tank 1 through the liquid filling port. When the volume of the liquid zone 4 is not enough to meet the continuous entry of the flushing liquid, the diaphragm 2 will be stretched to the inflation zone 3 side under pressure to expand the volume of the liquid zone 4 until the liquid addition action is completed. During the operation, when it is necessary to increase the perfusion pressure of the flushing liquid, the gas supply mechanism is used to inflate the gas area 3, so that the volume in the gas area 3 continues to increase, and the diaphragm 2 is pressed to stretch toward the liquid area 4, squeezing the flushing liquid in the liquid area 4, thereby increasing the perfusion pressure of the flushing liquid; when it is necessary to reduce the perfusion pressure of the flushing liquid, the air in the gas area 3 is extracted through the gas supply mechanism, so that the volume in the gas area 3 continues to decrease, and the volume in the liquid area 4 increases accordingly, and the pressure of the flushing liquid on the diaphragm 2 is reduced, thereby reducing the perfusion pressure of the flushing liquid. At the same time, during the operation, when the flushing liquid in the infusion tank 1 is insufficient, the cover plug 6 above the liquid area 4 can be opened to add flushing liquid to the liquid area 4 from the liquid filling port, so as to avoid the need for the staff to suspend the operation to replace the infusion tank 1, thereby reducing the risk of the operation.

[0023] For easier understanding, please refer to Figure 1 and Figure 2The gas delivery mechanism includes an electric air pump 7, which is connected to the top of the gas area 3 through an air delivery pipe 11. The electric air pump 7 can fill air into the gas area 3 through key control, and can also suck out the air in the gas area 3, so that the staff can adjust the perfusion pressure of the flushing liquid in time according to the surgical situation during the operation. At the same time, the electric air pump 7 can accurately control the amount of inflation or deflation, and accurately adjust the perfusion pressure of the flushing liquid. The infusion tube 5 is provided with an infusion regulator 8, and the staff can adjust the flow rate of the flushing liquid in the infusion tube 5 through the infusion regulator 8. The infusion tank 1 is made of transparent material, and the staff can directly observe the remaining flushing liquid in the liquid area 4 through the side wall of the infusion tank 1. A scale mark 9 is provided on the outside of the liquid area 4, which can more accurately judge the remaining flushing liquid in the liquid area 4. A non-contact liquid level alarm 10 is provided on the outside of the liquid area 4. When the liquid level alarm 10 detects that the liquid level of the flushing liquid in the infusion tank 1 reaches a preset value, the liquid level alarm 10 issues a warning to remind the staff to replenish the flushing liquid in time.

[0024] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
