Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a conjunctival sac negative pressure suction device. Background Art

[0002] Ophthalmic surgery is a delicate operation. For many eye diseases, surgery is the preferred treatment method. Common ones include cataract surgery, glaucoma surgery, eye trauma surgery, and strabismus correction surgery. During the operation, the eyes need to be held open to fully expose the surgical site. However, due to the spherical shape of the eyeball, secretions and blood will appear in the patient's eyes during the operation. These secretions and blood will flow along the eyeball to the conjunctival sac and affect the clarity of the surgical field. Therefore, negative pressure suction of the conjunctival sac is often required.

[0003] The existing conjunctival sac negative pressure suction generally consists of a suction tube connected to a suction device, and then the suction tube is aimed at the conjunctival sac for negative pressure suction. However, in actual operation, an assistant is required to assist in holding the suction tube, and the coordination between the surgeon and the assistant is relatively difficult, and it affects the surgical field of view, which may affect the surgeon's surgical progress. In addition, holding the suction tube for a long time may cause fatigue to the assistant, affect the stability of the suction tube, and affect the effect of the operation. Therefore, in response to the above problems, we propose a conjunctival sac negative pressure suction device. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a conjunctival sac negative pressure suction device, so that the suction tube can be fixed around the eye for adjustment and fixation. During the operation, the assistant can avoid holding the suction tube, thereby reducing the difficulty of cooperation between the surgeon and the assistant and avoiding the poor stability of the suction tube affecting the effect of the operation.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is: a conjunctival sac negative pressure suction device, comprising a positioning strip one and a positioning strip two connected to the two ends of the positioning strip one, the positioning strip one and the positioning strip two are both arc-shaped with openings arranged opposite to each other, the positioning strip one is provided with a slide groove, a slider is slidably connected to the slide groove, a fixing component for fixing the slider is provided in the slide groove, the fixing component comprises a plurality of spring leaves, a plurality of the spring leaves are connected to the inner wall of one side of the slide groove, and a plurality of the spring leaves are equidistantly arranged along the length extension direction of the inner wall of the slide groove, a suction channel is provided in the slider, a suction tube connected to one end of the suction channel is provided at the upper end of the slider, a drainage tube connected to the other end of the suction channel is provided at the lower end of the slider, an arc-shaped through groove is provided on one side of the positioning strip one, one end of the drainage tube extends to the outside of the arc-shaped through groove and is connected to the negative pressure suction device through a connecting pipe.

[0006] The beneficial effects of the utility model are as follows: by placing the first positioning strip at the upper eyelid and the second positioning strip at the lower eyelid, the part that needs to be suctioned is determined, and the slider is slid to determine the position. Then, when the slider is fixed, the slider is inserted between two adjacent spring sheets to fix the slider. By turning on the negative pressure suction device, negative pressure is generated in the suction tube to absorb secretions and blood in the conjunctival sac, thereby avoiding the assistant holding the suction tube, reducing the difficulty of cooperation between the surgeon and the assistant, and avoiding the poor stability of the suction tube affecting the effect of the operation.

[0007] In order to collect the liquid that is not adsorbed in time;

[0008] As a further improvement of the above technical solution: the cross sections at both ends of the positioning strip 1 and the cross section of the positioning strip 2 are both concave.

[0009] The beneficial effect of this improvement is: when the doctor uses saline solution to flush the conjunctival sac during the operation, a large amount of saline solution will overflow. At this time, the suction tube may fail to absorb the saline solution in time during the adsorption process. At this time, the two ends of the positioning strip one and the depressions on the positioning strip two can collect the saline solution to prevent the saline solution from overflowing and contaminating the patient's face, and then the suction tube can absorb it.

[0010] In order to collect the physiological saline entering the depressions at both ends of the positioning strip 1 and the depressions on the positioning strip 2;

[0011] As a further improvement of the above technical solution: a guide pipe is provided inside the positioning strip 2, both ends of the guide pipe extend into the interior of the positioning strip 1, a plurality of water seepage holes connected to the guide pipe are provided on the positioning strip 1 and the positioning strip 2, and a water outlet pipe is connected to the guide pipe, and a collection bag is connected to the end of the water outlet pipe away from the guide pipe.

[0012] The beneficial effect of this improvement is that when the physiological saline enters the depressions at both ends of the positioning strip one and the depressions on the positioning strip two, the physiological saline will enter the guide tube through the seepage holes, and then flow into the collection bag through the outlet pipe, and then the liquid in the collection bag will be uniformly treated.

[0013] To improve surgical safety;

[0014] As a further improvement of the above technical solution: a valve is provided on the water outlet pipe.

[0015] The beneficial effect of this improvement is that after the physiological saline entering the depressions at both ends of positioning strip one and the depressions on positioning strip two is collected, the valve can be closed to prevent the liquid in the collection bag from flowing back and re-entering positioning strip two to contaminate the patient's eyes.

[0016] In order to fix the positioning strip 1 and the positioning strip 2 around the eye;

[0017] As a further improvement of the above technical solution: a film is provided on the side of the positioning strip 1 and the positioning strip 2 away from the suction tube.

[0018] The beneficial effect of this improvement is that, through the setting of the film, the film can be attached to the patient's eye area, so that there is no gap between the positioning strips 1 and 2 and the skin around the eyes, thereby preventing liquid from seeping out.

[0019] To improve the flexibility of the suction tube;

[0020] As a further improvement of the above technical solution: the suction tube is a metal shaped hose.

[0021] The beneficial effects of this improvement are: the metal shaped hose can be bent and twisted, can adapt to different angles and shapes, is easy to operate in complex parts such as the conjunctival sac, and better contacts and absorbs liquids. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the suction end of the suction tube 7 can be made of rubber, silicone and other materials, and the tube wall of the suction end is thin, so that it can touch the conjunctival sac during suction without causing damage to the conjunctival sac, thereby avoiding causing discomfort to the patient; the cross-sections of the two ends of the positioning strip 1 and the cross-section of the positioning strip 2 are both concave, and when the doctor uses physiological saline to flush the conjunctival sac during the operation , a large amount of saline will overflow. At this time, during the adsorption process, the saline may not be adsorbed in time by the suction tube 7. At this time, the two ends of the positioning strip 1 and the recessed parts on the positioning strip 2 can collect the saline to prevent the saline from overflowing and contaminating the patient's face, and then the suction tube 7 can adsorb it; the interior of the positioning strip 2 is provided with a guide tube 11, and both ends of the guide tube 11 extend to the interior of the positioning strip 1, and the positioning strips 11 and 2 are provided with a plurality of seepage holes 12 connected to the guide tube 11, and the guide tube 11 is connected with a water outlet pipe 13, and the end of the water outlet pipe 13 away from the guide tube 11 is connected to a collection bag 14. When the saline enters the recessed parts at both ends of the positioning strip 1 and the positioning strip 2, the water outlet pipe 13 is connected to the collection bag 14. When the physiological saline enters the depressions at both ends of the positioning strip 1 and the depressions on the positioning strip 2, the physiological saline will enter the guide tube 11 through the seepage hole 12, and then flow into the collection bag 14 through the outlet pipe 13, and then the liquid in the collection bag 14 is uniformly processed; the outlet pipe 13 is provided with a valve 15, and when the physiological saline entering the depressions at both ends of the positioning strip 1 and the depressions on the positioning strip 2 is collected, the valve 15 can be closed to prevent the liquid in the collection bag 14 from flowing back and re-entering the positioning strip 2 to pollute the patient's eyes; the positioning strips 1 and 2 are provided with a film 16 on the side away from the suction tube 7, and through the setting of the film 16, the film 16 can be attached to the patient's eye area, so that there is no gap between the positioning strips 1 and 2 and the skin around the eyes, preventing liquid from seeping out;The suction tube 7 is a metal shaped hose, which can be bent and twisted to adapt to different angles and shapes, making it easier to operate in complex parts such as the conjunctival sac and better contact and absorb liquid.

At this time, the slider 4 is stuck between two adjacent reeds 5 to fix the slider 4. Then, the adsorption position of the suction tube 7 is adjusted. When the doctor needs to flush the conjunctival sac during the operation, a large amount of physiological saline is flushed into the conjunctival sac, and at the same time, the negative pressure suction device 10 is turned on, and the suction tube 7 will flush the conjunctival sac. The saline is adsorbed by the physiological saline, which enters the suction channel 6 through the suction tube 7, and then is collected through the drainage tube 8 and the connecting tube 17. At the same time, the doctor can adjust the suction position of the drainage tube 8 at any time according to the part that needs to be sucked. Due to the large amount of physiological saline, some physiological saline will overflow at this time and flow into the depressions at both ends of the positioning strip 1 and the depressions on the positioning strip 2, and then enter the guide tube 11 through the seepage hole 12, and then enter the outlet pipe 13 and flow into the collection bag 14. When the conjunctival sac is flushed, the valve 15 is closed to prevent the liquid from flowing back. During the operation, the utility model can avoid the assistant holding the suction tube 7, reduce the difficulty of cooperation between the surgeon and the assistant, and avoid the poor stability of the suction tube 7 affecting the operation effect.
