Description

Technical Field

[0001] The present invention relates to the technical field of drainage devices, and specifically relates to an anti-blocking negative pressure drainage device for gynecological surgery. Background Art

[0002] The drainage device used in gynecological surgery is a medical device for helping to drain body fluid or blood in the body, or clearing blood stasis or tissues in the uterus. The use of such devices is usually to aspirate tissue specimens or clean the surgical field, etc. After the operation, tissue samples need to be retained for pathological detection using a microscope. Before the pathological detection of the tissue samples drained during the operation, different substances such as blood clots and flushing fluids usually need to be separated to avoid the influence of mixed substances on the detection results. In addition, if the size of the tissue samples or blood clots aspirated during the operation is large, it is also easy to cause blockage during the aspiration process. For this reason, we propose an anti-blocking negative pressure drainage device for gynecological surgery. Summary of the Invention

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-4 , the present invention provides a technical solution: an anti-blocking negative pressure drainage device for gynecological surgery, including a suction tube 1 and a negative pressure tank 5. One side of the suction tube 1 is penetrated with a distal suction device tube 2. A separation device 3 for crushing solid lesion samples is arranged inside the suction tube 1. The bottom of the separation device 3 is fixedly communicated with a separation and suction mechanism 4 for solid-liquid separation. The bottom of the separation and suction mechanism 4 is inserted into the negative pressure tank 5. One side of the negative pressure tank 5 is fixedly communicated with a negative pressure suction tube 6. A positioning mechanism 7 for fixing the bottom of the separation and suction mechanism 4 is arranged on the top of the negative pressure tank 5.

[0018] Among them, the arranged negative pressure tank 5 and negative pressure suction tube 6 are connected to an external suction device, so that the whole device can be provided with attraction force. Subsequently, the arranged distal suction device tube 2 can extract tissues, flushing fluid, etc. during the operation into the suction tube 1. Then, the separation device 3 can be used to stir and crush the lesion samples, so as to prevent the lesions from blocking the separation and suction mechanism 4. The arranged separation and suction mechanism 4 can complete solid-liquid separation, which is convenient for separating and centrally extracting solid lesions. When the separation and suction mechanism 4 is connected to the negative pressure tank 5, the positioning mechanism 7 can be used for connection, so as to prevent the separation and suction mechanism 4 from detaching from the inside of the negative pressure tank 5 during drainage.

[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 , the separation device 3 includes a driving motor 10, a stirring rod 11 and a separation rod 12. A first connection hole 8 communicated with the distal suction device tube 2 is opened on one side of the suction tube 1. A second connection hole 9 communicated with the separation and suction mechanism 4 is opened at the bottom of the suction tube 1. A driving motor 10 is fixedly installed on the top of the suction tube 1. The output end of the driving motor 10 is fixedly connected with a stirring rod 11 extending into the suction tube 1. The separation rod 12 is fixedly connected to the outside of the stirring rod 11.

[0020] After the tissue, the flushing liquid, etc. are sucked into the inside of the suction tube 1, the drive motor 10 operates, and the drive motor 10 drives the stirring rod 11 and the separating rod 12 to rotate rapidly. In this way, the separating rod 12 can be used to collide and break the tissue lesions, etc., so that the material can be broken.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the separation and suction mechanism 4 includes a separation and suction tube 13, a filter screen 14 and a tearing groove 15. A filter screen 14 is fixedly installed inside the separation and suction tube 13, and tearing grooves 15 are formed on both sides of the separation and suction tube 13.

[0022] After the separation mechanism 3 processes, it will flow into the inside of the separation and suction tube 13. Subsequently, liquid tissue fluid, etc. will be filtered out through the filter screen 14, while the remaining solid tissue, etc. will remain inside the separation and suction tube 13. When the drainage is completed, the set tearing groove 15 can facilitate tearing the separation and suction tube 13, so that it is convenient to centrally pick up the tissue inside the separation and suction tube 13.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the positioning mechanism 7 includes a first clamping block 16, a second clamping block 17, a locking rope 18, a loop fastener 19 and a hook fastener 20. The top of the negative pressure tank 5 and outside the separation and suction mechanism 4 are fixedly connected with a first clamping block 16 and a second clamping block 17 made of elastic material. A locking rope 18 is fixedly connected to one side of the second clamping block 17. A loop fastener 19 is fixedly connected to one side of the locking rope 18, and a hook fastener 20 bonded to the loop fastener 19 is fixedly connected to the other side of the locking rope 18.

[0024] When the separation and suction mechanism 4 is installed, it can be inserted between the first clamping block 16 and the second clamping block 17 made of elastic material, so that the preliminary clamping and positioning of the separation and suction mechanism 4 can be completed. Subsequently, the locking rope 18 is wound around the outside of the first clamping block 16 and the second clamping block 17, and the loop fastener 19 and the hook fastener 20 are bonded to each other, so as to prevent the separation and suction mechanism 4 from detaching from the negative pressure tank 5.

[0025] Please refer to Figure 1 and Figure 2 As shown in, a clogging prevention tube 21 is penetrated through the distal suction tube 2, and a sealing plug 22 is inserted into one end of the clogging prevention tube 21 away from the distal suction tube 2.

[0026] Wherein, when the distal suction tube 2 is blocked, the sealing plug 22 can be opened, and the syringe is connected to the anti-blocking tube 21, so that the syringe can be used to increase the pressure to punch and remove the blockage at the blocked position.

[0027] Please refer to Figure 1 and Figure 2 Both the top of the first clamping block 16 and the top of the second clamping block 17 are fixedly connected with a guiding block 23 with an arc-shaped top. The arc-shaped guiding blocks 23 provided at the tops of the first clamping block 16 and the second clamping block 17 can prevent the separation and suction mechanism 4 from being bent when it becomes loose.

[0028] During use, first, the set negative pressure tank 5 and the negative pressure suction tube 6 are connected to an external suction device, so that the entire device can be provided with suction force. Subsequently, the set distal suction tube 2 can extract tissues, flushing fluid, etc. during the operation into the inside of the suction tube 1. Then, the separation device 3 can be used to stir and crush the lesion sample, thereby preventing the lesion from causing blockage of the separation and suction mechanism 4. The set separation and suction mechanism 4 can complete solid-liquid separation, facilitating the separation and centralized extraction of solid lesions. When the separation and suction mechanism 4 is connected to the negative pressure tank 5, the positioning mechanism 7 can be used for connection, so that the separation and suction mechanism 4 can be prevented from detaching from the inside of the negative pressure tank 5 during drainage. After the tissue and flushing fluid, etc. are suctioned into the inside of the suction tube 1, the drive motor 10 operates, and the drive motor 10 drives the stirring rod 11 and the separation rod 12 to rotate rapidly, so that the separation rod 12 can collide and crush the tissue lesions, etc., so that the material can be crushed. After being processed by the separation mechanism 3, it will flow into the separation and suction tube 13. Subsequently, liquid tissue fluid, etc. will be filtered out through the filter screen 14, and the remaining solid tissue, etc. will remain inside the separation and suction tube 13. When the drainage is completed, the set tearing groove 15 can facilitate tearing the separation and suction tube 13, so that it is convenient to centrally pick up the tissue inside the separation and suction tube 13. When the separation and suction mechanism 4 is installed, it can be inserted between the first clamping block 16 and the second clamping block 17 made of elastic material, so that the preliminary clamping and positioning of the separation and suction mechanism 4 can be completed. Subsequently, the locking rope 18 is wound around the outside of the first clamping block 16 and the second clamping block 17, and the rough surface magic tape 19 and the hook surface magic tape 20 are bonded to each other, so that the separation and suction mechanism 4 can be prevented from detaching from the negative pressure tank 5. When the distal suction tube 2 is blocked, the sealing plug 22 can be opened, and the syringe is connected to the anti-blocking tube 21, so that the syringe can be used to increase the pressure to punch and remove the blockage at the blocked position.
