Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of intraoperative instruments of endoscopic surgery. More specifically, the utility model relates to a kind of intraoperative specimen collection device of hysteroscopy surgery. BACKGROUND

[0002] Endoscopic surgery is a surgical method that surgeons complete in vitro by inserting camera lens and surgical instruments into the body. During the operation, the miniature camera head at the front end of the disposable camera suction tube is used to directly detect the uterine cavity, quickly and accurately locate abnormal tissues, and perform point negative pressure suction to suck out abnormal tissues in the abdominal cavity or uterine cavity. It is suitable for artificial abortion, diagnostic curettage, hysteroscopic endometrial polyp electroresection, etc. When specimens need to be collected during the operation, the operator needs to pause the operation, remove the suction tube at one end, then transfer the specimen tissue, and then insert the suction tube. When multiple collections are encountered, medical staff need to repeatedly insert and remove the suction tube, and surgical waste often contaminates surgical instruments and the environment. In addition, in clinical practice, some tissues often remain or stick to the inner wall of the suction tube, and medical staff need to repeatedly fold and squeeze the suction tube, which not only damages the suction tube, but also causes some specimen tissues to be unable to be transferred to the specimen container. Especially when there is less tissue, it is difficult to collect specimen tissue, which affects subsequent treatment. SUMMARY

[0003] An object of the present utility model is to solve at least the above problems and provide at least the advantages to be explained later.

[0004] Another object of the present utility model is to provide an intraoperative specimen collection device for hysteroscopy surgery, which can quickly transfer the required specimen tissue to the specimen container during the operation without repeatedly inserting and removing the suction tube. The abnormal tissue specimen remaining in the main pipe body can also be quickly and accurately transferred to the specimen container, and the postoperative specimen collection work can be quickly and accurately completed.

[0005] To achieve these objects and other advantages according to the present utility model, an intraoperative specimen collection device for hysteroscopy surgery is provided, which comprises:

[0006] A main pipe line comprising a main pipe body, the main pipe body having a suction tube connected at one end and a negative pressure suction device connected at the other end;

[0007] A collection pipe line comprising a branch pipe body passing through the main pipe body, the free end of the branch pipe body being detachably connected to a negative pressure source;

[0008] and control valves are respectively arranged on the main pipe body and the branch pipe body to control the opening and closing of the main pipe body and the branch pipe body. The control valves control the opening and closing of the main pipe line and the collection pipe line respectively. When the tissue is sucked in the operation, the main pipe line is kept open and the collection pipe line is closed. When the specimen is collected, the main pipe line is directly closed, the collection pipe line is opened, and the negative pressure source is started. The branch pipe body and the main pipe body can be integrally formed or detachably connected through a three-way piece. If the specimen collection is not needed, the branch pipe body can not be connected. When the main pipe line works, the abnormal specimen tissue is first sucked into the upstream section of the main pipe body. Then, the main pipe body is clamped, the branch pipe body is opened, and the negative pressure source is started to suck the specimen tissue into the branch pipe body and then into the specimen tube. The whole process does not need to plug and unplug the suction pipe line of the main pipe body. If part of the tissue is retained on the inner wall of the main pipe body, the type of the negative pressure source can be switched to increase the suction pressure.

[0009] Preferably, the control valve comprises a first valve body arranged on the main pipe body and located downstream of the interface between the branch pipe body and the main pipe body in the suction direction.

[0010] A second valve body is arranged on the branch pipe body. The first valve body and the second valve body can be automatic electromagnetic valves or manual valves, which can control the opening and closing of the main pipe line and the collection pipe line.

[0011] Preferably, the negative pressure source is a balloon. In the initial state, the second valve body is in the clamped state. After the balloon is emptied in the initial state, the second valve body is opened, and the specimen tissue is transferred into the branch pipe body by the air suction pressure of the balloon, which is convenient for the subsequent collection and transfer of the specimen.

[0012] Preferably, the negative pressure source is a negative pressure machine which is detachably connected to the free end of the branch pipe. In the initial state, the second valve body is in the clamped state. The negative pressure source is used to suck the specimen temporarily retained in the main pipe body into the branch pipe body, which is convenient for collection. Therefore, the negative pressure machine detachably connected to the free end of the branch pipe body can adjust the suction force according to the volume and type of the specimen, which effectively ensures the complete collection of the specimen.

[0013] Preferably, a filter is arranged between the free end of the branch pipe body and the negative pressure source. The filter is, for example, a filter screen which is, for example, pasted on the end of the free end of the branch pipe body to filter the unnecessary blood or waste water.

[0014] Preferably, the main pipe body and the branch pipe body are integrally formed. The main pipe body and the branch pipe body can also be detachably connected through a tee connector. The main pipe body and the branch pipe body are made of medical non-toxic transparent soft polyvinyl chloride plastic or high-performance polyolefin thermoplastic elastomer material. The commonly used infusion tube material is adopted to facilitate the modification of the existing pipeline and reduce the medical cost.

[0015] Preferably, the filter is a filter groove sleeved on the free end of the branch pipe body.

[0016] Preferably, a connecting hole is formed in the side wall of the main pipe body, and the connecting hole is communicated with the branch pipe body; and the diameter of the connecting hole is larger than the diameter of the main pipe body. When the diameter of the connecting hole is larger than the diameter of the main pipe body, a small amount of specimen can be retained.

[0017] Preferably, the first valve body and the second valve body are both Robert clamps. Thus, all components of the utility model can be made disposable; and cross infection is avoided.

[0023] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] As Figure 1 , Figure 2 indicated, the utility model provides a hysteroscope operation in -specimen collection device, it includes:

[0025] The main pipeline includes a main pipe body 100, one end 101 of the main pipe body 100 is connected with a suction pipe, the other end 102 is connected with a negative pressure suction device;

[0026] The collection pipeline includes a branch pipe body 200 through the main pipe body 100, and the free end of the branch pipe body 200 is connected with a negative pressure source 300;

[0027] And control valve 400 is arranged on the main pipe body 100 and branch pipe body 200 respectively, and the main pipe body 100 and branch pipe body 200 are controlled to be alternately connected and disconnected.The control valve 400 controls the main pipeline and the collection pipeline to be alternately connected and disconnected respectively;When suctioning tissue in operation, the main pipeline is kept through, and the collection pipeline is disconnected;When collecting specimen, the main pipeline is closed, the collection pipeline is opened, the negative pressure source is started, and the specimen tissue to be collected is suctioned into the branch pipe body, which is convenient for transferring into a specimen bottle.

[0028] When using, one end of the main pipe body 100 is connected to the negative pressure suction device, the other end is connected with the suction tube, the main pipe body 100 is communicated to carry out suction work, and the abnormal tissue removed in the uterine cavity is suctioned into the main pipe body 100;Then, the control valve on the main pipe body 100 is closed, and the control valve on the branch pipe body 200 is opened;The abnormal tissue specimen temporarily stored in the main pipe body 100 is suctioned into the branch pipe body 200 by starting the negative pressure source 300, which can be quickly transferred into a specimen container.In the process of collecting specimen, the main pipe body 100 does not need to be repeatedly plugged and unplugged, so that the required specimen can be quickly and accurately collected under the condition that the operation is normally carried out.The difficulty of collecting specimen is greatly reduced, and the required specimen tissue can be quickly and accurately obtained.

[0029] In one of the embodiments, as Figure 1 indicated, the control valve 400 includes a first valve body 401 arranged on the main pipe body 100, and the first valve body 401 is located downstream of the interface between the branch pipe body 200 and the main pipe body 100 in the suction direction;Thus, when collecting specimen tissue, the first valve body 401 can be started after observing that the specimen tissue reaches the predetermined position of the main pipe body 100, so that the suction pipeline is cut off, and the specimen tissue is temporarily stored in the main pipe body 100.

[0030] A second valve body 402 is arranged on the branch pipe body 200. The second valve body 402 is used to cut off the passage of the branch pipe body 200 in the initial state, and open the passage of the branch pipe body 200 when collecting specimen tissues, so that the negative pressure source 300 can suck the specimen tissues from the main pipe body 100 into the branch pipe body 200, and then transfer them into the specimen container. The first valve body 401 and the second valve body 402 are, for example, Robert clamps, which can be controlled by medical staff with one hand, thereby improving the efficiency and greatly reducing the medical cost.

[0031] In one embodiment, as shown in Figure 1 the negative pressure source 300 is an inflatable balloon. In the initial state, the second valve body 402 is in a clamped state. The negative pressure source 300 is, for example, an ear sucker. In the initial state, the medical staff first squeezes the ear sucker, then starts the second valve body 402 to pass through the branch pipe body 200, and finally releases the ear sucker to use its suction force to suck the temporarily stored specimen tissues into the branch pipe body 200.

[0032] In one embodiment, as shown in Figure 2 the negative pressure source 300 is a negative pressure machine. In the initial state, the second valve body 402 is in a clamped state. The negative pressure source 300 is used to suck the specimen tissues temporarily stored in the main pipe body 100 into the branch pipe body 200. The negative pressure source 300 is, for example, an electric negative pressure machine, which is detachably connected to the free end of the branch pipe body 200. When collecting specimens, the negative pressure machine is started. The negative pressure source 300 can be a gas source that can provide a certain suction force. The negative pressure machine can adjust its suction force in real time according to the type, required amount and collection times of the specimen tissues, thereby facilitating the control of the medical staff.

[0033] In one embodiment, as shown in Figure 1 a filter 600 is arranged between the free end of the branch pipe body 200 and the negative pressure source 300. The filter 600 is, for example, a filter tank, which includes a tubular member sleeved on the free end of the branch pipe body 200 and a filter screen arranged in the tubular member. The filter 600 can also be a filter membrane, which is, for example, adhered to the end of the free end of the branch pipe body 100, so as to filter the unnecessary blood or waste water.

[0034] In one embodiment, as shown in Figure 2As shown in the drawings, the main pipe body 100 and the branch pipe body 200 are integrally formed. The axis of the main pipe body 100 and the axis of the branch pipe body 200 have an included angle less than 90 degrees, for example; the branch pipe body 200 extends to the other end 102 of the main pipe body 100, so that the suction direction of the negative pressure source 300 is more inclined to the other end 102 of the main pipe body 100, facilitating rapid suction of the specimen tissue in the main pipe body 100 and improving specimen collection efficiency.

[0035] In one embodiment, as shown in the drawings, Figure 1 The main pipe body 100 and the branch pipe body 200 can also be detachably connected by a tee connector 500. Thus, when specimen collection is not required, the branch pipe body 200 can be disconnected, improving treatment efficiency. The main pipe body 100 and the branch pipe body 200 are made of medical non-toxic transparent soft polyvinyl chloride plastic or high-performance polyolefin thermoplastic elastomer material. The use of common infusion tubing facilitates the modification of existing pipelines to reduce medical costs.

[0036] In one embodiment, as shown in the drawings, Figure 1 The negative pressure source 300 is detachably connected to the free end of the branch pipe body 200. Thus, the negative pressure source 300 can be switched to different components according to the type and state of the postoperative specimen to provide appropriate suction force. In particular, for smaller or larger specimens, the negative pressure source can be switched in real time to ensure accurate specimen collection.

[0037] In one embodiment, as shown in the drawings, Figure 2 As shown in the drawings, a connecting hole 103 is formed in the side wall of the main pipe body 100, and the connecting hole 103 communicates with the branch pipe body 200; the diameter of the connecting hole 103 is greater than the diameter of the main pipe body 100. When the diameter of the connecting hole 103 is greater than the diameter of the main pipe body 100, a small amount of specimen can be retained directly at the connecting hole 103 during suction. When collecting the specimen, the negative pressure source 300 is started to suck the specimen retained at the inlet of the branch pipe body 200 into the branch pipe body 200, improving the efficiency of collecting the specimen.

[0038] In one embodiment, as shown in the drawings, Figures 1-2 As shown in the drawings, the first valve body 401 and the second valve body 402 are both Robert clamps. Thus, all components of the utility model can be made disposable; cross infection is avoided.

[0039] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
