Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a percutaneous bile duct puncture channel blocking device. Background Art

[0002] Percutaneous bile duct puncture is an interventional medical procedure used to treat or diagnose bile duct disease. During this procedure, the doctor will puncture the skin and then guide a catheter into the bile duct to treat bile duct obstruction. When the bile duct is obstructed, such as by gallstones or tumors, percutaneous bile duct puncture can help drain bile and relieve symptoms. After percutaneous bile duct puncture treatment, the puncture channel needs to be closed to prevent infection, bleeding, bile leakage or other complications.

[0003] During the current percutaneous bile duct puncture surgery, the puncture channel blocking method mostly uses spring coils and homemade gelatin sponge strips to block the tube wall. It has high technical requirements and cannot achieve the effect of rapid blocking. In addition, the incision site of the puncture skin lacks isolation from the external environment and is prone to bacterial infection. In order to solve the above problems, we propose a percutaneous bile duct puncture channel blocking device to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a percutaneous bile duct puncture channel blocking device, which solves the problem that the existing percutaneous bile duct puncture surgery takes a long time for puncture blocking, has high technical requirements, and cannot achieve a rapid blocking effect.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a percutaneous bile duct puncture channel blocking device, comprising a puncture tube, a sheath tube is arranged inside the puncture tube, an air bag is arranged inside the sheath tube, and a protective layer is arranged on the surface of the air bag; and

[0007] A barrier component is arranged on the surface of the puncture tube, and the barrier component includes a support tube, which is threadedly connected to the surface of the puncture tube, a first blocking pad is fixedly connected to the surface of the puncture tube, one side of the first blocking pad is fixedly connected to the blocking tube, and one end of the blocking tube is fixedly connected to the second blocking pad.

[0008] The present invention is further configured such that elastic strips are fixedly connected inside the first blocking pad and the second blocking pad, and the other side of the second blocking pad is in contact with the support tube.

[0009] The present invention is further configured such that the support tube and the second blocking pad are both slidably connected to the surface of the puncture tube, and the surface of the puncture tube is provided with threads;

[0010] When the puncture channel needs to be blocked, the medical staff inserts the sheath tube (101) into the puncture tube (1), and the sheath tube (101) drives the airbag (102) and the protective layer (103) to penetrate the puncture tube (1) and contact the puncture channel. Then, the external inflation device is started to allow high-pressure gas to enter the air inlet pipe (4) and inflate the airbag (102). After the airbag (102) is inflated, it expands rapidly and expands the protective layer (103) rapidly, so that the protective layer (103) quickly contacts the inner wall of the puncture channel. When the compressed gelatin sponge absorbs moisture from the surrounding tissue and expands, the pressure of the airbag (102) is gradually reduced, thereby achieving the effect of rapid blocking.

[0011] The present invention is further configured such that the protective layer is made of compressed gelatin sponge, and the first blocking pad and the second blocking pad are the same in size.

[0012] The present invention is further configured such that one side of the airbag is connected to an air inlet pipe, and the other end of the air inlet pipe penetrates to the outside of the puncture tube.

[0013] The present invention is further configured such that the surface of the support tube is fixedly connected with anti-slip rubber, and the airbag is made of medical silicone.

[0014] The present invention has the following beneficial effects:

[0015] The present invention provides an airbag, which can be moved into the puncture channel through the puncture tube after the puncture treatment is completed. The airbag is connected to the external inflation device through the air inlet pipe. The airbag can be inflated and expanded to compress the gelatin sponge of the protective layer used for blocking and make it fit with the tube wall to achieve the effect of rapid blocking. Through the setting of the barrier component, the first blocking pad and the second blocking pad can be used to block and shield the external wound of the patient during the puncture treatment to prevent bacteria from entering and play a protective role.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment 1

[0026] See also Figure 1-4 The present invention is a percutaneous bile duct puncture channel blocking device, comprising a puncture tube 1, a sheath tube 101 is arranged inside the puncture tube 1, an air bag 102 is arranged inside the sheath tube 101, and a protective layer 103 is arranged on the surface of the air bag 102; and

[0027] The barrier component 2 is arranged on the surface of the puncture tube 1, and the barrier component 2 includes a support tube 201, the support tube 201 is threadedly connected to the surface of the puncture tube 1, a first blocking pad 202 is fixedly connected to the surface of the puncture tube 1, a blocking tube 203 is fixedly connected to one side of the first blocking pad 202, and a second blocking pad 204 is fixedly connected to one end of the blocking tube 203.

[0028] Specifically, an internal thread is provided on the inner wall of the support tube 201, and an external thread is provided on the surface of the puncture tube 1. The internal thread and the external thread are matched with each other, so that the left and right positions can be adjusted when the support tube 201 is rotated. The first sealing pad 202 and the second sealing pad 204 are both made of medical silicone material, which can shield and protect the puncture wound of the patient. The sealing tube 203 is between the first sealing tube 203 and the second sealing tube 203. When the first sealing tube 203 and the second sealing tube 203 are squeezed against each other, the sealing tube 203 can achieve the effect of spacing. Specific embodiment 2

[0030] See also Figure 1-4 On the basis of the first specific embodiment, the first blocking pad 202 and the second blocking pad 204 are both fixedly connected with elastic strips 3, the other side of the second blocking pad 204 is in contact with the support tube 201, the support tube 201 and the second blocking pad 204 are both slidably connected to the surface of the puncture tube 1, and the surface of the puncture tube 1 is provided with threads.

[0031] Specifically, the elastic strip 3 is respectively fixed inside the first blocking pad 202 and the second blocking pad 204. When the first blocking pad 202 and the second blocking pad 204 are squeezed, the blocking pads are arched outward to achieve the effect of sealing the wound. The protective layer 103 is made of compressed gelatin sponge. The main function of the compressed gelatin sponge is to expand by absorbing moisture from the surrounding tissue, thereby filling the cavity or channel to achieve a sealing effect. The compressed gelatin sponge can usually seal blood vessels or other body cavities to a certain extent to prevent bleeding or liquid leakage. Specific embodiment three

[0033] See also Figure 1-4 On the basis of the first and second specific embodiments, the protective layer 103 is made of compressed gelatin sponge, the first blocking pad 202 and the second blocking pad 204 are of the same size, one side of the airbag 102 is connected to the air inlet pipe 4, and the other end of the air inlet pipe 4 passes through the outside of the puncture tube 1, the surface of the support tube 201 is fixedly connected with anti-slip rubber, and the airbag 102 is made of medical silicone.

[0034] Specifically, one side of the airbag 102 is connected to an air inlet pipe 4, which can connect the airbag 102 to an external inflation device to achieve the effect of quickly expanding the protective layer 103. The anti-slip rubber arranged on the surface of the support tube 201 can increase the friction of the surface of the support tube 201. The airbag 102 is made of medical silicone and has a good anti-infection effect.

[0035] The working principle of the present invention is as follows: during puncture treatment, the puncture tube 1 is inserted into the patient's body. When the puncture tube 1 moves, it will drive the first blocking pad 202 to move. When the first blocking pad 202 is completely moved into the patient's body, the medical staff manually rotates the support tube 201, and the support tube 201 moves to the right through the thread action. When the support tube 201 moves, it pushes the second blocking pad 204 to move. After the first blocking pad 202 and the second blocking pad 204 are squeezed, they will be arched at the inside and outside of the patient's wound at the same time, so as to achieve the effect of sealing the wound. Figure 4 As shown, bacteria are prevented from entering and the protective effect is improved. After the puncture treatment is completed, when the puncture channel needs to be blocked, the medical staff inserts the sheath 101 into the puncture tube 1, and the sheath 101 drives the airbag 102 and the protective layer 103 to penetrate the puncture tube 1 and contact the puncture channel. Then, the external inflation device is started to allow high-pressure gas to enter the air inlet pipe 4 and inflate the airbag 102. After inflation, the airbag 102 expands rapidly and the protective layer 103 expands rapidly, so that the protective layer 103 quickly contacts the inner wall of the puncture channel. When the compressed gelatin sponge absorbs moisture from the surrounding tissue and expands, the pressure of the airbag 102 is gradually reduced to achieve the effect of rapid blocking.
