As shown in fig. 1, the construction of the mouse uterus 5 is described: the livestock uterus is divided into three parts, namely a uterine horn 51, a uterine body 52 and a cervix 53. From the anterior end of the cervix 53 to the base of the uterus is the uterus 52. The anterior end of the cervix 53 is in communication with the uterus 52 and the posterior end protrudes into the vagina, referred to as the vaginal portion of the cervix 53. The tissue structure is serosa, myolayer and mucous membrane from outside to inside.
The medicine rod 4 is a medicine-containing solid rod, and the medicine rod 4 is placed into the uterus 5 of the mouse to directly act on the uterus 5 of the mouse, so that the therapeutic effect is achieved. Because some medicine sticks 4 are tough in texture and the mouse uterus 5 is soft in texture, and the thickness of the medicine sticks 4 is not very different from that of the mouse uterus 5, the medicine sticks 4 are difficult to put into the mouse uterus 5, and the medicine sticks 4 are not easy to fix at specific positions of the uterus. In order to solve the technical problems, the utility model provides a device for placing a medicine rod 4 into a mouse uterus 5.
As shown in fig. 2-4, in one embodiment of the present utility model, a device for inserting a medicine stick 4 into a uterus 5 of a mouse is provided, comprising: a sleeve 1 and a binding wire 3; the sleeve 1 comprises a penetrating section 13, a spike part 14 for penetrating the uterus 5 of a mouse is arranged at the end part of the penetrating section 13, a containing cavity is arranged in the penetrating section 13, and the inner diameter of the containing cavity is larger than the outer diameter of the medicine rod 4; the binding wire 3 penetrates through the medicine rod 4, two ends of the binding wire 3 protrude out of two ends of the medicine rod 4, and two ends of the binding wire 3 can be bound on the uterus 5 of the mouse to fix the medicine rod 4.
The sleeve 1 is a hollow sleeve 1 with a harder tip, the medicine rod 4 is a medicine-containing solid rod, the binding wire 3 is an operation wire (absorbable) embedded in the middle of the medicine rod 4, as shown in fig. 4, the position of the solid rod can be adjusted by pulling the binding wire 3, and after the solid rod is placed into the uterus 5 of a mouse, both ends of the operation wire can be knotted, so that the fixing effect is achieved.
When in use, the solid stick is put into the sleeve 1, as shown in figure 2, the spike part 14 of the sleeve 1 penetrates through the uterine wall to enter the cavity, the sleeve 1 is slowly moved forward to enable the traditional Chinese medicine stick 4 to enter a fixed position on one side of the uterus, then the sleeve 1 is continuously pushed forward, the spike part 14 penetrates through the uterine wall, the binding wire 3 is pulled on the opposite side to slowly withdraw the sleeve 1, the medicine stick 4 is remained in the uterus 5 of a mouse, the binding wires 3 at two ends of the medicine stick 4 are used for knotting, and the position of the medicine stick 4 is fixed.
Therefore, the medicine rod 4 is smoothly placed into the uterus 5 of the mouse through the sleeve 1 of the placement device, the problem that the flexible medicine rod 4 is difficult to place into the soft uterus is solved, the binding wires 3 at the two ends of the medicine rod 4 are used for knotting, the medicine rod 4 is ensured to be fixed at a specific position of the uterus 5 of the mouse, and the optimal treatment effect is realized.
