Technical Field

[0001] The utility model relates to the technical field of intestinal surgery, in particular to a specimen taking-out device for intestinal surgery. Background Art

[0002] During intestinal surgery under laparoscopy, after cutting off the intestinal lesion sample, the medical oval forceps insert the sterile plastic tube sleeve into the rectum through the anus. With the assistance of the leader, the assistant places the completely free rectal specimen into the sterile plastic tube sleeve and tightens the white edge band at the end of the sterile plastic tube sleeve. The assistant then pulls the specimen out of the body through the rectal lumen to complete the removal of the specimen.

[0003] If the diameter of the sterile plastic tube sleeve is designed to be large, the patient will feel obvious discomfort during the process of inserting it into the rectum; if the diameter of the sterile plastic tube sleeve is designed to be small, the assistant will not be able to put the resected specimen into the sterile plastic tube sleeve, and the operation is very inconvenient. Therefore, an intestinal specimen removal device is needed, which can realize the opening and locking actions of the sampling site through external operation during sampling. Utility Model Content

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] In the description of the present invention, it should be noted that if there are terms indicating orientation or positional relationship such as "upper", "lower", "inner", "back", etc., they are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, if there are terms such as "first", "second", etc., they are also used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] This embodiment relates to a specimen removal device for intestinal surgery, the overall structure of which is as follows: Figure 1-5 As shown, it includes:

[0037] A straight rod 1, wherein a through hole 101 is provided inside the straight rod 1, and a handle 102 is provided below the straight rod 1;

[0038] A specimen collection bag 2 is arranged on one side of the straight rod 1;

[0039] The straight rod 1 is provided with a tying elastic wire 3 for opening and locking the specimen collection bag 2.

[0040] The specimen collection bag 2 can be opened and locked and sealed by the tying elastic wire 3. When the specimen collection bag 2 is inserted into the rectum, it is in a contracted state and the overall diameter is small, so the patient basically does not feel any discomfort. When the specimen collection bag 2 enters the collection site, the specimen collection bag 2 can be opened from the outside by pushing the tying elastic wire 3 at the bottom of the handle 102, so as to facilitate the insertion of the intestinal sample.

[0041] A further optimized solution is that circular holes 103 are provided on both sides of the straight rod 1, and the circular holes 103 and the through hole 101 are vertically connected. One end of the tying elastic wire 3 passes through one of the circular holes 103 and is fixed at the position of the circular hole 103; the other end of the tying elastic wire 3 passes through the other circular hole 103 and passes out from the bottom of the through hole 101 of the straight rod 1.

[0042] See also Figure 3-Figure 5 As shown, when the elastic tying wire 3 is open, the end of the elastic tying wire 3 is pulled downward at the bottom of the handle 102, and the circular ring formed by the elastic tying wire 3 between the two circular holes 103 is reduced. The elastic tying wire 3 is continuously pulled to lock the circular ring part on the straight rod 1.

[0043] The elastic tying wire 3 has a certain toughness. When the elastic tying wire 3 is pushed upward, the corresponding ring expands, so that the ring can be expanded and locked by pushing and pulling the elastic tying wire 3 at the bottom of the handle 102.

[0044] A further optimized solution is that a connecting film 201 is provided on the outer periphery of the specimen collection bag 2, and a channel 202 is formed between the connecting film 201 and the specimen collection bag 2; the tying elastic wire 3 between the two circular holes 103 is provided on the outside of the straight rod 1 and passes through the channel 202 to form a supporting portion for opening and locking the specimen collection bag 2.

[0045] When the ring (support part) expands and contracts, it can drive the specimen collection bag 2 to expand or lock. When the specimen collection bag 2 is in the locked state, the overall diameter is small. When inserted into the rectum, the patient will basically not feel discomfort. When the specimen collection bag 2 reaches the collection position, the specimen collection bag 2 is opened to facilitate the collection of intestinal samples. When the intestinal sample is placed inside the specimen collection bag 2, the specimen collection bag 2 is tightened, and the intestinal sample can be locked and sealed inside the specimen collection bag 2, and the intestinal sample removal process will not cause pollution.

[0046] When sampling, the sampling site can be opened and locked by external operation. The intestinal sampling process is simple to operate and convenient to use.

[0047] The circular holes 103 , the elastic tying wires 3 and the supporting parts are arranged in multiple groups in the vertical direction of the straight rod 1 , so as to lock the specimen collection bag 2 at different positions.

[0048] A label plate 301 is arranged at the bottom of the elastic tying wire 3 , and numbers are marked on the label plate 301 for distinguishing the locking of different positions of the specimen collection bag 2 ; the specimen collection bag 2 at different positions can be opened and locked according to the label plate 301 at the bottom.

[0049] A further optimized solution is that a support tube 104 is provided under the handle 102, and a U-shaped groove 105 is provided on one side of the support tube 104 for fixing the label plate 301 at the bottom of the tying elastic wire 3; when the specimen collection bag 2 is locked, the label plate 301 at the bottom of the corresponding tying elastic wire 3 can be clamped in the position of the U-shaped groove 105 at the bottom of the handle 102 to prevent the tying elastic wire 3 from loosening and prevent the specimen collection bag 2 at the corresponding position from loosening.

[0050] It is worth mentioning that a cap 106 is provided on the top of the straight rod 1 to close the top of the through hole 101; the straight rod 1, the specimen collection bag 2 and the tying elastic wire 3 are all made of medical materials. The cap 106 is provided to close the top of the straight rod 1, and the top of the cap 106 is in an arc shape, which can ensure that the straight rod 1 is smoothly inserted into the rectum.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
