Detailed Description
The application claims a uterus sacculus support with a movable sheath, as shown in figures 1-2, comprising: a connection tube 100 having a guide wire lumen 110 and a balloon inflation lumen 120 independent from each other; an expandable balloon 200 configured to expand in response to air or water pressure applied to the interior of the balloon inflation lumen 120 at the interior thereof; a balloon sheath 300 sleeved outside the connection tube 100 and capable of sliding to a first position and a second position relative to the connection tube 100, wherein the balloon sheath has an inner cavity 310, the inner cavity 310 is used for accommodating the unexpanded expandable balloon 200 at the first position, and the inner cavity 310 is separated from the expandable balloon 200 at the second position; a multi-lumen connector, which is provided with a guide wire connector 410 communicated with the guide wire cavity 110 and an inflation cavity connector 420 communicated with the balloon inflation cavity 120, wherein the guide wire connector 410 and the guide wire cavity 110 are positioned on the same straight line, and the inflation cavity connector 420 is provided with a one-way valve 421; a guide wire (not shown) is inserted into the guide wire lumen 110 through the guide wire connector 410.
In the following, only the technical solution is explained in connection with the treatment process, the present application claims a uterus balloon stent with a movable sheath, which has an expandable balloon 200 and a balloon sheath 300, the balloon sheath 300 is sleeved outside the connecting tube 100 and can slide to a first position and a second position relative to the connecting tube 100, the balloon sheath 300 has an inner cavity 310, the inner cavity 310 is used for accommodating the unexpanded expandable balloon 200 at the first position, the inner cavity 310 is separated from the expandable balloon 200 at the second position, during the pushing the stent into the patient, the balloon sheath 300 is at the first position, so that the unexpanded expandable balloon 200 is compressed in the inner cavity 310 of the balloon sheath 300 until the inner end of the connecting tube 100 is pushed into the uterus, the balloon sheath 300 is pushed outwards to the second position, the expandable balloon 200 is released from the inner cavity 310, and then air pressure or water pressure is applied to the expandable balloon 200 to expand the expandable balloon, the stent is in contact with the uterine cavity wall to avoid adhesion, the expandable balloon 200 is protected in the process of pushing the stent into a patient, and compared with the existing stent which directly pushes the expanded expandable balloon 200 into the body of the patient, the vaginal extrusion in the pushing process is avoided, the foreign body sensation is reduced, and the vaginal damage is avoided; the expandable balloon 200 is inserted into the uterus and then taken out, the connecting pipe 100 is recovered to be soft, and the foreign body sensation of a patient is reduced; the inflation cavity joint 420 is provided with a one-way valve 421, so that when gas or liquid is inflated into the expandable balloon 200, backflow is prevented, continuous expansion of the expandable balloon 200 is ensured, repeated expansion and contraction of the expandable balloon 200 at an affected part are avoided, and pain of a patient caused by treatment is reduced.
It should be noted that, in the present technical solution, the balloon sheath 300 is configured to be slidable to the first position and the second position, and the balloon sheath 300 is always sleeved on the connecting tube 100 no matter at the first position or at the second position or at any position, and as for the specific position and the distance between the first position and the second position, the present application is not limited, but it should be noted that, when the balloon sheath 300 is located at the first position, the depth of the inner end of the balloon sheath 300 relative to the inner end of the connecting tube 100 entering the human body is certainly deeper, and the difference of the depth of the inner end of the balloon sheath 300 relative to the inner end of the connecting tube 100 is smaller than the thickness of the uterine cavity 310 of the general human body, however, when the stent reaches the designated position, the inner end of the connecting tube 100 is used as the reference, and is not related to the position of the inner end of the balloon sheath 300, and when the balloon sheath 300 is located at the first position, the balloon sheath 300, the medical staff can conveniently control the balloon sheath 300 to slide outwards to the second position, and when the balloon sheath 300 is at the second position, the depth of the inner end of the balloon sheath 300 entering the human body is necessarily shallower relative to the inner end of the connecting pipe 100.
It should be noted that the term "inner end" and "outer end" in this application are used to describe the ends of a component during treatment, the end of the component that enters the body first is the inner end, the end that enters the body last or does not enter the body as the catheter is gradually pushed into the body is the outer end, and there is no reference in the definition between the inner end and the outer end of different components. And "inward" and "outward" indicate movement toward and away from the human body, respectively.
As an improvement of the above technical solution, the balloon sheath 300 is transparent, and the connection tube 100 is provided with a positioning point 140 for marking the movement of the balloon sheath 300 to the second position, so that when a medical worker can specifically know that the balloon sheath 300 slides to the marking point during treatment, the inner end of the balloon sheath 300 is separated from the expandable balloon 200, the movement of the balloon sheath 300 is controlled more scientifically, and the accident that the expandable balloon 200 bursts the balloon sheath 300 due to the fact that the medical worker judges the balloon sheath by mistake depending on experience is avoided.
As an improvement of the above technical solution, the present application further provides another embodiment, a body temperature probe is disposed on the expandable balloon 200, the multi-lumen connector further includes a body temperature detection connector, and the connection pipe 100 further has a body temperature data transmission line for connecting the body temperature probe and the body temperature detection connector, so as to detect whether there is infection or damage during the tube placement and treatment process, so as to cause abnormal temperatures of vagina and uterus, and facilitate medical staff to take timely measures.
In order to detect whether the expandable balloon 200 enters the uterus in real time and improve the accuracy of tube placement, there are various means, as an improvement of the technical scheme, a plurality of scale marks 130 are marked on the connecting tube 100, and medical staff can judge whether the expandable balloon 200 enters the uterus according to the scales exposed outside the patient and the position area of organs in the body; certainly, the determination may also be made by acquiring image data in the body of the patient, specifically, the connection tube 100 is further provided with a camera and a camera lumen, the camera is arranged at the inner end of the connection tube 100, the camera lumen comprises a camera data transmission line and a light source fiber tube which are independent of each other, and the multi-lumen joint further comprises a video signal joint for receiving signals of the camera data transmission line; in addition, a visualization ring is disposed at the inner end of the connection tube 100, and the position of the visualization ring is tracked by an external device to determine whether the expandable balloon 200 enters the uterus of the patient.
Besides, in order to avoid the damage caused by the direct contact of the inner end of the guide wire with the inner wall of the vagina or the inner wall of the uterus, the inner end of the guide wire cavity 110 is arranged to be blocked, which is also an improvement of the technical scheme.
The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
