Description

Technical Field

[0001] The utility model relates to the technical field of hysteroscopic surgery, in particular to an infusion pump water injection tube for hysteroscopic surgery. Background Art

[0002] Hysteroscopic surgery refers to a minimally invasive surgery performed using a hysteroscope. Hysteroscope is an advanced device for diagnosing and treating diseases within the uterine cavity. It can clearly observe various changes in the uterine cavity and make a clear diagnosis.

[0003] When a patient undergoes hysteroscopic surgery, it is necessary to inflate or inject water into the uterine cavity in order to expand the uterine cavity so that the doctor can clearly observe the internal structure of the uterus. At this time, a water injection tube is needed to connect the water injection pump to the hysteroscope. For example, the patent publication number CN 215230938 is an infusion pump water injection tube for hysteroscopic surgery. By setting an exhaust membrane, when the uterine swelling fluid passes through the improved infusion pump water injection tube, the exhaust membrane will discharge the air in the uterine swelling fluid to ensure that there are no bubbles in the uterine swelling fluid, thereby preventing air embolism caused by air entering the patient's uterine cavity along with the uterine swelling fluid.

[0004] In the above-mentioned and similar technical solutions, when the water injection pump is connected to the hysteroscope and water is injected into the patient's uterine cavity, since the water injection pump is directly connected to the hysteroscope, when the water injection is completed and the water in the patient's uterine cavity needs to be sucked out, the water injection pipe needs to be removed and replaced with a drainage pipe, and the drainage pipe needs to be connected to the hysteroscope, and the whole operation steps are cumbersome. Utility Model Content

[0005] The utility model aims to provide an irrigation pump water injection tube for hysteroscopic surgery to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an irrigation pump water injection tube for hysteroscopic surgery, comprising a main tube and a secondary tube sealed and plugged into the outer wall of one end of the main tube, the top and bottom outer walls of one end of the main tube are fixedly connected with buckles, and the top and bottom circumferential outer walls and inner walls of the secondary tube are provided with card slots;

[0007] The circumferential inner wall of the main pipe is provided with a sealing component for sealingly connecting the main pipe and the auxiliary pipe, and the circumferential inner wall of the main pipe is provided with a flow limiting component for reducing the injection flow rate and flow rate.

[0008] Furthermore, the sealing assembly includes a first inner tube, and the first inner tube is fixedly connected to the inner wall of one end of the main tube, the inner wall of one end of the main tube is fixedly connected with an extrusion spring, and the outer wall of the other end of the extrusion spring is fixedly connected with an extrusion ring, and the outer wall of the other end of the extrusion ring is fixedly connected with a sealing sheet.

[0009] Furthermore, the extrusion ring is sealingly sleeved on the circumferential outer wall of the first inner tube, and the circumferential outer wall of the auxiliary tube is fixedly connected to a plurality of cross bars distributed at equal distances, and the inner wall of one end of the auxiliary tube is fixedly connected to the second inner tube.

[0010] Furthermore, the outer wall of the other end of the main pipe is fixedly connected to the second connecting pipe, and the outer wall of one end of the auxiliary pipe is fixedly connected to the first connecting pipe.

[0011] Furthermore, the flow limiting assembly includes a limiting ring, and the limiting ring is fixed to the circumferential inner wall of the second connecting pipe, and a clamping rod is fixedly connected between the inner walls on both sides of the other end of the main pipe, a pull rope is fixedly connected to the outer wall of one end of the clamping rod, and a limiting flow ball is fixedly connected to the outer wall of one end of the pull rope.

[0012] Furthermore, the flow-limiting balls are all hollow structures, and a truncated cone-shaped flow-limiting groove is formed on the outer wall of one end of the limiting ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The invention discloses an irrigation pump water injection tube for hysteroscopic surgery. When an auxiliary tube is inserted into a main tube, a buckle can be inserted into the outer wall of the auxiliary tube along a clamping groove, and the auxiliary tube can be rotated. At this time, the main tube and the auxiliary tube can be quickly and tightly connected. When it is necessary to suck out the water accumulated in the patient's uterine cavity, the auxiliary tube can be directly rotated to remove the auxiliary tube, and then the drainage pipe can be connected to the main tube in the same way, thereby achieving the effect of quick replacement and quick water absorption.

[0015] At the same time, when the water flows from the auxiliary pipe into the main pipe, the water flow velocity and flow rate are relatively small. At this time, the water flow can enter the second connecting pipe normally. When the water flow velocity and flow rate suddenly increase, the flow limiting ball can be directly flushed up under the impact of the water flow, and the gap between the flow limiting ball and the limiting ring will affect the flow velocity and flow rate of the water flow, thereby limiting the flow of water.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When installing the drain pipe, it is also necessary to check the sealing of the drain pipe and the hysteroscope again to prevent the situation where the connection between the drain pipe and the hysteroscope is not tight, resulting in the water in the patient's uterine cavity cannot be completely sucked out. The process is time-consuming and can easily lead to long-term accumulation of water in the patient's uterine cavity, causing damage to the patient's uterine cavity.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an irrigation pump water injection pipe for hysteroscopic surgery, comprising a main pipe 1 and a sub-pipe 2 sealed and plugged into the outer wall of one end of the main pipe 1, the top and bottom outer walls of one end of the main pipe 1 are fixedly connected with buckles 5, and the top and bottom circumferential outer walls and inner walls of the sub-pipe 2 are provided with card grooves 6; the circumferential inner wall of the main pipe 1 is provided with a sealing component 8 for sealing the main pipe 1 and the sub-pipe 2, and the circumferential inner wall of the main pipe 1 is provided with a flow limiting component 9 for reducing the water injection flow rate and flow rate.

[0024] It should be noted that when the auxiliary tube 2 is inserted into the main tube 1, the buckle 5 can be inserted into the outer wall of the auxiliary tube 2 along the slot 6, and the auxiliary tube 2 can be rotated. At this time, the main tube 1 and the auxiliary tube 2 can be quickly and tightly connected. When it is necessary to suck out the accumulated water in the patient's uterine cavity, the auxiliary tube 2 can be directly rotated to remove the auxiliary tube 2, and then the drainage pipe can be connected to the main tube 1 in the same way, which can achieve the effect of quick replacement and quick water absorption.

[0025] like Figure 3 The sealing assembly 8 includes a first inner tube 801, and the first inner tube 801 is fixedly connected to the inner wall of one end of the main tube 1, the inner wall of one end of the main tube 1 is fixedly connected with an extrusion spring 802, and the outer wall of the other end of the extrusion spring 802 is fixedly connected with an extrusion ring 803, and the outer wall of the other end of the extrusion ring 803 is fixedly connected with a sealing sheet 804.

[0026] like Figure 1 and Figure 3 The extrusion ring 803 is sealingly sleeved on the circumferential outer wall of the first inner tube 801 , and the circumferential outer wall of the auxiliary tube 2 is fixedly connected with a plurality of cross bars 7 distributed at equal distances, and the inner wall of one end of the auxiliary tube 2 is fixedly connected with the second inner tube 10 .

[0027] It should be noted that when the auxiliary tube 2 is inserted, the second inner tube 10 will contact the sealing sheet 804, and under the action of the extrusion spring 802, when the main tube 1 and the auxiliary tube 2 are connected, the sealing sheet 804 can maintain a sealed fit with the second inner tube 10, thereby preventing the formation of blisters when water is injected into the patient's uterine cavity.

[0028] like Figure 1 The outer wall of the other end of the main pipe 1 is fixedly connected to the second connecting pipe 4, and the outer wall of one end of the auxiliary pipe 2 is fixedly connected to the first connecting pipe 3.

[0029] It should be noted that during use, the first connecting tube 3 is connected to the water outlet of the irrigation pump, and the second connecting tube 4 is connected to the hysteroscope.

[0030] like Figure 3 The flow limiting assembly 9 includes a limiting ring 901, and the limiting ring 901 is fixed to the circumferential inner wall of the second connecting pipe 4, and a clamping rod 904 is fixedly connected between the inner walls on both sides of the other end of the main pipe 1, and a pull rope 903 is fixedly connected to the outer wall of one end of the clamping rod 904, and a limiting flow ball 902 is fixedly connected to the outer wall of one end of the pull rope 903.

[0031] like Figure 4 The flow-limiting balls 902 are all hollow structures, and a truncated cone-shaped flow-limiting groove is opened on the outer wall of one end of the limiting ring 901.

[0032] It should be noted that when the water flows from the auxiliary pipe 2 into the main pipe 1, the water flow can normally enter the second connecting pipe 4 when the flow velocity and flow rate are relatively small. When the flow velocity and flow rate of the water flow suddenly increase, the flow limiting ball 902 can be directly flushed up under the impact of the water flow, and the gap between the flow limiting ball 902 and the limiting ring 901 will affect the flow velocity and flow rate of the water flow, thereby limiting the flow of water.

[0033] Working principle: connect the first connecting tube 3 to the water outlet of the perfusion pump, connect the second connecting tube 4 to the hysteroscope, when the auxiliary tube 2 is inserted into the main tube 1, the buckle 5 can be inserted into the outer wall of the auxiliary tube 2 along the card slot 6, and the auxiliary tube 2 can be rotated, at this time, the main tube 1 and the auxiliary tube 2 can be quickly and tightly connected, when it is necessary to suck out the accumulated water in the patient's uterine cavity, the auxiliary tube 2 can be directly rotated to remove the auxiliary tube 2, and then the drainage pipe can be connected to the main tube 1 in the same way, which can achieve the effect of rapid replacement and rapid water absorption. When the auxiliary tube 2 is inserted, the second inner tube 10 will contact the sealing sheet 804. When the water flows from the auxiliary tube 2 into the main tube 1, the water flow is at a low flow rate and flow rate. At this time, the water flow can normally enter the second connecting tube 4. When the flow rate and flow rate of the water flow suddenly increase, the flow limiting ball 902 can be directly flushed up under the impact of the water flow.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
