Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a hemostatic device after uterine surgery. Background Art

[0002] Some pregnant women who undergo cesarean sections do not have their cervix opened during the procedure. If bleeding occurs after the cesarean section, it is very difficult to deal with. In addition, how to cool the wound in the uterine cavity to slow down the bleeding is also a problem. Therefore, how to stop bleeding from the inner side of the uterus after surgery is a technical problem that needs to be solved urgently. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a post-hysterectomy hemostasis device.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A post-hysterectomy hemostasis device comprises a spiral elastic guide rod, a spiral elastic capsule sleeved on the elastic guide rod, and a first inflation / deflation unit for inflating or deflation of the spiral elastic capsule with gas or liquid. The two ends of the elastic capsule are fixed to the two ends of the elastic guide rod.

[0005] Preferably, the rear side of the spiral elastic sac has an annular elastic sac sleeved on the rear end of the elastic guide rod and a second inflation and deflation unit.

[0006] Preferably, the first inflation and deflation unit includes a first tube body connected to the rear end of the spiral elastic sac and a first valve connected to the first tube body; the second inflation and deflation unit includes a second tube body connected to the rear end of the annular elastic sac and a second valve connected to the second tube body.

[0007] Preferably, the elastic guide rod is a hollow and transparent guide rod, and the spiral elastic capsule is an elastic capsule made of a transparent material.

[0008] Preferably, the first inflation and deflation unit includes a first air hole on the inner wall of the rear end of the guide rod, a third tube body connected to the first air hole, and a third valve connected to the third tube body; the second inflation and deflation unit includes a second air hole on the inner wall of the rear end of the guide rod, a fourth tube body connected to the second air hole, and a fourth valve connected to the fourth tube body.

[0009] Preferably, the wall of the spiral elastic capsule gradually becomes thicker from front to back.

[0010] Preferably, an optical fiber endoscope is passed through the elastic guide rod.

[0011] The post-operative hemostatic device of the present invention is used by first rotating a spiral elastic guide rod and a spiral elastic capsule mounted on the elastic guide rod into the interior of the uterus from the cervical os. Then, the spiral elastic capsule is inflated with gas or liquid, causing the spiral elastic capsule to gradually expand, forming a cylindrical extrusion structure that compresses the inner wall of the uterus to stop bleeding at the post-operative site. Gas or liquid of a suitable temperature can be conveniently inflated as needed. After use, the device is drained of water or air, and then rotated out of the uterus from the cervical os.

[0012] Furthermore, the rear side of the spiral elastic sac is provided with an annular elastic sac which is sleeved on the rear end of the elastic guide rod. After the spiral elastic sac is filled with gas or liquid, the annular elastic sac can be filled with gas or liquid, so that the annular elastic sac expands into a spherical or pancake shape, becoming a fixed air bag of the internal cervical os, blocking the cervical os from the inside, and preventing the spiral elastic sac from falling out of the cervical os.

[0013] Furthermore, the elastic guide rod is a hollow and transparent guide rod, and the spiral elastic capsule is an elastic capsule made of a transparent material, so that an optical fiber endoscope can be inserted through the elastic guide rod to observe the condition of the inner wall of the uterus so as to adjust the treatment plan in time.

[0014] Furthermore, the wall of the spiral elastic sac gradually thickens from front to back. When gas or liquid is filled in, the spiral elastic sac deep in the uterus can be ensured to expand first. The spiral elastic sac expands from front to back and from inside to outside, ensuring the shape of the spiral elastic sac, avoiding the formation of dead angles, and better squeezing the inner wall of the uterus.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1 A device for stopping bleeding after uterine surgery, such as Figure 1 and Figure 3 As shown, it includes a spiral elastic guide rod 2, a spiral elastic sac 1 mounted on the elastic guide rod, and a first inflation and deflation unit for inflating and discharging gas or liquid for the spiral elastic sac, and the two ends of the elastic sac are fixed to the two ends of the elastic guide rod; the rear side of the spiral elastic sac is provided with an annular elastic sac 3 mounted on the rear end of the elastic guide rod and a second inflation and deflation unit; the elastic guide rod can be solid or hollow. In this embodiment, the elastic guide rod is a hollow and transparent guide rod. Specifically, the hollow guide rod can be made of an elastic transparent plastic tube; the spiral elastic sac is an elastic sac made of transparent material. In this embodiment, silicone material can be used, such as the material for making condoms; the sac wall of the spiral elastic sac gradually becomes thicker from front to back. In addition, the cross-section of the spiral elastic sac and the annular elastic sac can be circular or annular; when the cross-section is circular, the spiral elastic sac and the annular elastic sac respectively form an air / liquid storage cavity with the elastic guide rod, and when the cross-section is annular, the spiral elastic sac and the annular elastic sac themselves have an air / liquid storage cavity, and the spiral elastic sac and the annular elastic sac can be fixed between the elastic guide rods by bonding or tying with cable ties.

[0019] The first inflation and deflation unit includes a first tube body 4 connected to the rear end of the spiral elastic sac and a first valve 5 connected to the first tube body; the second inflation and deflation unit includes a second tube body 6 connected to the rear end of the annular elastic sac and a second valve 7 connected to the second tube body.

[0020] When using the post-uterine hemostasis device of this embodiment, the spiral elastic guide rod and the spiral elastic sac mounted on the elastic guide rod are first rotated from the cervical opening into the interior of the uterus, and then the spiral elastic sac is filled with gas or liquid, so that the spiral elastic sac gradually expands to form a cylindrical extrusion structure, which squeezes the inner wall of the uterus to stop bleeding at the post-operative position; gas or liquid of appropriate temperature can be very conveniently filled as needed. After use, the uterus can be removed from the cervical ostium by draining the water or air. The spiral elastic capsule has an annular elastic capsule on the rear side of an elastic guide rod. After the spiral elastic capsule is filled with gas or liquid, the annular elastic capsule can be subsequently filled with gas or liquid, causing the annular elastic capsule to expand into a spherical or pancake shape, blocking the cervical ostium from the inside and preventing the spiral elastic capsule from dislodging from the cervical ostium. The elastic guide rod is hollow and transparent, and the spiral elastic capsule is made of a transparent material. This allows a fiberoptic endoscope to be inserted through the elastic guide rod to observe the condition of the uterine inner wall and adjust the treatment plan in a timely manner. The capsule wall of the spiral elastic capsule gradually thickens from front to back, ensuring that the spiral elastic capsule deep in the uterus expands first when gas or liquid is added. The spiral elastic capsule expands from front to back and from the inside out, maintaining its shape, avoiding the formation of blind spots, and effectively squeezing the uterine inner wall.

[0021] Example 2 Different from Example 1, Figure 2 As shown, the first inflation and deflation unit includes a first air hole on the inner wall of the rear end of the guide rod, a third tube body 8 connected to the first air hole, and a third valve 9 connected to the third tube body; the second inflation and deflation unit includes a second air hole on the inner wall of the rear end of the guide rod, a fourth tube body 10 connected to the second air hole, and a fourth valve 11 connected to the fourth tube body.

[0022] The difference from the first embodiment is that an optical fiber endoscope (not shown) is passed through the transparent elastic guide rod.

[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical scope disclosed by the present invention and who makes equivalent substitutions and changes based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
