Description

Technical Field

[0001] The present invention belongs to the technical field of hemostasis, and in particular relates to a deformable hemostatic device. Background Art

[0002] In clinical practice, relatively deep wounds are often encountered. For example, gunshot wounds, penetration of hard objects through the skin, or minor surgical operations in emergency situations can all cause deep wounds with large bleeding amounts. If it is a wound at the limb end, usually a ligature is used to stop bleeding at the proximal end of the limb, completely blocking the blood circulation. Although this hemostatic method stops the bleeding at the bleeding site, it also blocks the blood circulation in other parts of the limb at the same time. If the hemostasis lasts for a long time, limb necrosis may occur. Or, the method of pressing to stop bleeding is adopted, but the effect of pressing to stop bleeding for deep wounds is not obvious. In addition, during uterine cavity examination and treatment, uterine cavity bleeding is also involved. Most of the existing hemostatic methods are to insert cotton balls near the uterine cavity. Especially when the contraction of the two uterine cornua or the lower uterine segment is poor and hemostasis is needed, the existing hemostatic methods have poor effects. Therefore, it is necessary to design a hemostatic instrument that can be applied to deep wounds, especially to the uterine cavity. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0028] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0029] A deformable hemostatic device, as Figures 1 to 5 shown, includes a tubular connecting body 1. By way of example, the connecting body is made of a transparent flexible tube. A balloon 2 is installed on the connecting body, and a distal drainage opening 3 is provided at one end of the balloon extending outside the connecting body. At least one proximal drainage opening 4 is provided on the side of the connecting body where the balloon faces outwards. Preferably, the connecting body penetrates through the balloon, and the distal drainage opening is arranged at the end of the connecting body.

[0030] An inner core 5 is connected to the balloon. The inner core passes through the connecting body. After pulling the inner core tightly towards the outer end of the connecting body, the balloon is sleeved at the end of the connecting body. The limiting ring 12 on the connecting body forms a limiting effect on the balloon. Moreover, a drainage channel is formed between the inner core and the inner wall of the connecting body, and the inner core has an operation section extending outside the connecting body. The balloon can be quickly installed by means of the inner core, and the balloon can be quickly inserted into the wound by means of the connecting body, solving the problem of difficult replacement clinically.

[0031] The end of the connector facing outward is provided with a flushing port 6 and an outer drainage port 7, and the flushing port and the outer drainage port are arranged obliquely relative to the connector. In order to achieve a better hemostatic effect, in an optional embodiment, the balloon surface is coated with a drug layer 8. In another optional embodiment, the balloon surface is coated with gauze. Further, the gauze is coated with a drug layer to achieve a better hemostatic effect.

[0032] As an example, the connector is provided with two proximal drainage ports on the side of the balloon facing outward, and the two proximal drainage ports are symmetrically arranged on both sides of the connector. Usually, the proximal drainage ports are axially perpendicular to the axis of the connector. The flushing port and the outer drainage port are symmetrically arranged on both sides of the connector. The flushing port is shorter than the outer drainage port.

[0033] In an optional embodiment, if Figures 2 to 5 As shown, two probes 9 are provided on the connector on the outward side of the balloon, and the two probes are symmetrically arranged on both sides of the connector. In a further improved scheme, support rods 10 are provided on the outward side of the balloon corresponding to the positions of the probes, and a driving mechanism for driving the support rods is provided in the connector.

[0034] As an example, Figure 6 As shown, the driving mechanism includes a lifting rod 11 arranged in the connecting body, and the inner end of the lifting rod is hinged to the support rod, such as Figure 7 As shown, by pulling the lifting rod, the two support rods can be expanded to both sides, and then the probe position corresponding to the balloon can be expanded, so that the probe can have a better field of view, and the bleeding position can be observed more clearly and intuitively, which is convenient for the hemostasis operation to be targeted. In addition, in actual use, the lifting rod can be pulled and retracted multiple times, so that the support rod can continuously perform the opening-closing-opening action, so that the field of view of the probe position is better. In addition, there is a proximal drainage port near the probe, and the proximal drainage port can be used to absorb the liquid near the probe. Therefore, through the synergistic effect of the support rod and the proximal drainage port, the field of view of the probe position can be maximized, which is more conducive to hemostasis and treatment.

[0035] When used for emergency treatment of intrauterine bleeding, a drainage bag can be connected to the external drainage port, and the hemostatic effect can be judged according to the drainage situation. After the balloon is inserted for hemostasis with the help of the connector, the hemostatic effect of the uterine cavity can be observed dynamically in real time through the probe. The shape of the balloon can change with the change of the shape of the uterine cavity, especially when the contraction of the uterine horns on both sides or the lower segment of the uterus is poor and hemostasis is needed, the conventional balloon cannot achieve a good compression hemostasis effect. The balloon in the invention can form an adaptive shape according to the shape of the uterus and the bleeding site, thereby achieving a good hemostatic effect.

[0036] The structure of the present invention is simple, reasonable in design and convenient to operate. By using a transparent hose as a connector, the balloon can be inserted into the inner side of a deeper wound through the hose for hemostasis. At the same time, an external connecting pipe is connected to the external drainage port to drain the liquid in the wound, effectively assisting in hemostasis. Moreover, the balloon can adaptively change its size with the contraction of the wound site, with strong adaptability and good hemostasis effect.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
