Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a radiation-proof screen for transjugular intervention surgery. Background Art

[0002] Interventional therapy is a minimally invasive surgery performed under the guidance of imaging equipment, and most of these interventional surgeries are performed under the guidance of a digital subtraction angiography (DSA). The DSA tube generates X-rays when it is working, and the rays pass through the human body to play a real-time X-ray guidance role. But at the same time, X-rays will inevitably cause ionizing radiation losses to the operator. Therefore, interventional surgery must have adequate safety protection. The basic principles of radiation protection are time protection, distance protection, and shielding protection, that is, to shorten the exposure time to radiation as much as possible, to increase the distance from the X-ray tube as much as possible, and to use various protective facilities and personal protective equipment. Transjugular approach for interventional surgery (including transjugular intrahepatic portosystemic shunt, transjugular liver puncture biopsy, transjugular inferior vena cava filter placement, etc.) is a common approach for interventional surgery. However, this approach requires the operator to stand on the head side of the DSA examination bed to perform the operation. There is no effective lead curtain to shield the operator, which causes the operator to be almost completely exposed near the DSA balloon. In addition, some interventional surgeries take a long time, and the operator's personal protective equipment such as lead clothes, lead skirts, and lead neckbands cannot meet the needs of radiation protection. In the long run, it will inevitably lead to occupational injuries to the operator. In order to strengthen the radiation protection of transjugular interventional surgery, the current approach relies on the operator to increase the number of protective equipment used, such as wearing multiple layers of lead clothes and lead skirts, but this method inevitably increases the burden on the operator and greatly increases the risk of the operator suffering from cervical, thoracic, lumbar and other diseases. During transjugular intervention, the operator needs to stand on the side of the patient's head, and all operations require the operator to hold his hands in the air, which can easily cause fatigue and reduce surgical accuracy. Chinese utility model CN214965802 U discloses a movable lead screen for transjugular intrahepatic portosystemic shunt, comprising a base, a fixed lead screen is mounted on the base, a sliding lead screen is arranged outside the fixed lead screen, upper and lower slide rails are fixed on both sides of the base, the upper and lower slide rails are cooperatively connected with the sliding lead screen, an operation notch is arranged on one side of the sliding lead screen, a small table that can be stored is arranged inside the sliding lead screen, and universal wheels are arranged at the bottom of the base. The above device provides arm support for the operator by arranging a small table inside the sliding screen and an operation notch, but the angle of the operator's arm placement is unchanged, and the operator will still feel tired after a long time, which affects the accuracy of the operation. Summary of the invention

[0003] The technical problem solved by the utility model is that during the transjugular interventional surgery, the operator needs to stand beside the patient's head and all operations require the operator to hold both hands in the air, which easily leads to fatigue and reduces the accuracy of the surgery.

[0004] The utility model provides a radiation protection screen for transjugular interventional surgery, comprising a radiation protection panel and an elbow support, the radiation protection panel comprising a lead plate and a support base, the lead plate being a rectangular plate, the lower end of the lead plate being connected to the support base, the elbow support being a structure with both sides bent upward and the middle portion concave, an adjustment component being connected to the lower portion of the elbow support, the adjustment component comprising a lifting rod and a movable base, the movable base comprising two parallel clamping blocks and a locking bolt, the upper ends of the two clamping blocks being connected by a connecting plate to form a mounting groove with an opening at the lower end, the mounting groove being buckled on the top of the radiation protection panel, one of the clamping blocks being provided with a locking hole, the locking bolt passing through the locking hole and abutting against the radiation protection panel for locking, a connecting pipe for being sleeved with the lifting rod being provided on the outer side of the other clamping block, an elastic clip for locking the lifting rod being provided on the top of the connecting plate, the lifting rod and the connecting pipe being clearance-matched, when the elastic clip is in a loosened state, the lifting rod can move up and down and rotate left and right relative to the movable base through the connecting pipe.

[0005] Furthermore, the elbow rest is a support pad made of rubber material.

[0006] Furthermore, the surface of the elbow rest is wrapped with a leather layer.

[0007] Furthermore, the support base is made of stainless steel.

[0008] Furthermore, the lead plate is 104 cm long, 5.5 cm wide and 86.5 cm high.

[0009] Furthermore, short stainless steel rods are connected between the two sides of the lower end of the rectangular plate and the support base.

[0010] The utility model has the following beneficial effects: (1) The elbow rest of the utility model is liftable, movable, and adjustable in angle. The position, height, and angle of the elbow rest can be adjusted according to the height of the operator and the operation habits of the operator, so as to comfortably support the operator's left arm. The right arm only needs to be suspended for operation, which significantly improves the stability and convenience of the operator's operation. (2) During transjugular intervention, the sterile surgical sheet needs to completely cover the patient's head, and the operation is performed only through a small opening on the sterile sheet, which often causes the patient to have difficulty breathing. The elbow rest of the device can also support the sterile sheet to facilitate the patient's normal breathing. (3) The radiation protection panel of the utility model is placed on the head side of the DSA examination bed, that is, between the X-ray tube and the operator, which effectively shields the rays emitted by the X-ray tube, reduces the operator's X-ray exposure during the operation, and plays a role in radiation protection.

[0012] In order to clearly illustrate the technical features of this solution, the solution is described below through specific implementation methods and in combination with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the utility model.

[0013] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0014] like Figure 1 As shown, a radiation-proof screen for transjugular interventional surgery includes a radiation-proof panel and an elbow rest. The radiation-proof panel includes a lead plate 1 and a support base 2. The lead plate 1 is a rectangular plate with a length of 104 cm, a width of 5.5 cm, and a height of 86.5 cm. The lower end of the lead plate 1 is connected to the support base 2, which is made of stainless steel. Stainless steel short rods are connected between the two sides of the lower end of the lead plate 1 and the support base 2 to form a triangular fixation. The fixing position of the stainless steel short rod is lower than the lowest edge of the C-arm of the DSA machine, which does not affect the anteroposterior and lateral rotation of the C-arm during the operation.

[0015] The elbow support 3 is a structure with two sides bent upward and a concave middle part. The elbow support 3 is a support pad made of rubber material, with a leather layer wrapped on the surface. The lower part of the elbow support 3 is connected to an adjustment component. The adjustment component includes a lifting rod 4 and a movable base. The movable base includes two parallel clamping blocks and a locking bolt 6. The upper ends of the two clamping blocks are connected by a connecting plate to form a mounting groove with an opening at the lower end. The mounting groove is buckled on the top of the radiation protection panel. One of the clamping blocks is provided with a locking hole. The locking bolt 6 passes through the locking hole and abuts against the radiation protection panel to lock it. When the locking bolt 6 is in a loose state, the position of the movable base on the radiation protection panel can be adjusted according to the surgical habit of the surgeon. The outer side of the other clamping block is provided with a connecting pipe 7 for sleeve connection with the lifting rod 4. The top of the connecting plate is provided with an elastic clip 5 for locking the lifting rod 4. The lifting rod 4 and the connecting pipe 7 are clearance-matched. When the elastic clip 5 is in a loose state, the lifting rod 4 can move up and down and rotate left and right relative to the movable base through the connecting pipe 7, thereby adjusting the height and angle of the elbow support 3.

[0016] During the operation, the DSA examination bed is raised to a comfortable height for the operator, and the device is inserted horizontally under the C-arm so that the device is located between the X-ray tube and the operator. A sterile sheet is laid, and the height and angle of the elbow support 3 are adjusted according to the height of the operator so that it supports the operator's left arm. The operator only needs to operate with the right arm suspended in the air, which significantly improves the stability and convenience of the operator's operation. At the same time, during the transjugular intervention, the sterile surgical sheet needs to completely cover the patient's head, and the operation is only performed through a small opening on the sterile sheet, which often causes the patient to breathe laboriously. The elbow support 3 of the device can also support the sterile sheet to facilitate the patient's normal breathing. The handheld radiation detector is located on one side of the X-ray tube and the DSA machine is working. The radiation dose is measured to be 0.193 uSv / h. After the device is removed, the radiation dose is measured again to be 11.040 uSv / h. The radiation dose differs by nearly 10 times, indicating that the device can effectively shield the X-rays generated by the DSA tube during the transjugular intervention surgery and significantly reduce the X-ray radiation dose received by the operator.
