Description

Technical Field

[0001] The present invention relates to the field of interventional surgery auxiliary instruments, and in particular to an image interventional surgery treatment auxiliary device. Background Art

[0002] Interventional imaging surgery is a minimally invasive surgical method that uses guidewires, catheters and other instruments to diagnose and treat diseases under the guidance of imaging equipment. Its characteristics include small incisions (only the size of a grain of rice), small trauma, fast recovery, and good efficacy. Interventional imaging surgery is widely used in many fields, such as the treatment of tumors, hemangiomas, and various types of bleeding.

[0003] In addition to guidewires and catheters, the main instruments involved in imaging interventional surgery usually include vascular sheaths, also known as catheter sheaths. They are mainly used to establish an access channel from the skin to the vascular cavity to facilitate the repeated introduction of instruments such as catheters, guidewires or stents into the blood vessels, allowing interventional surgery to be performed more smoothly and safely.

[0004] During existing imaging interventional surgeries, when introducing instruments into blood vessels, the surgeon usually holds the instrument to be introduced into the blood vessel and the vascular sheath at the same time. In order to facilitate the repeated introduction of instruments, the vascular sheath is usually fixed in a simple way or not fixed at all. Although this method provides convenience for the process of introducing instruments into the blood vessels, the vascular sheath is prone to displacement during other operations of the imaging interventional surgery. In addition to affecting the surgical incision, it may also interfere with the operation of the instrument in the blood vessel. In summary, there is an urgent need for an auxiliary device that can facilitate the surgeon to take the vascular sheath for use at any time and can effectively fix the vascular sheath. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an image interventional surgery treatment auxiliary device, which is used to effectively fix the vascular sheath and ensure that the vascular sheath can be conveniently taken and used at any time.

[0008] Furthermore, the fixing ring includes a first elastic fixing band and a second elastic fixing band, one end of the first elastic fixing band and the second elastic fixing band are hinged to the fixing box, and the first elastic fixing band and the second elastic fixing band are respectively provided with a first adhesive portion and a first adhesive surface on the surface of the side away from the fixing box, and the first adhesive portion and the first adhesive surface are detachably connected.

[0009] Furthermore, the end surface of the fixing box close to the fixing ring is an arc-shaped structure, and an anti-slip gasket is arranged in the arc-shaped structure area.

[0010] Further, the telescopic assembly includes a telescopic cavity opened inside the fixed box, a first piston plate and a second piston plate slidably connected to the telescopic cavity, the first piston plate is located between the second piston plate and the top wall of the telescopic cavity, and the first piston plate does not contact the second piston plate, a tension spring is arranged between the first piston plate and the top wall of the telescopic cavity, and a compression spring is arranged between the second piston plate and the bottom of the telescopic cavity;

[0011] An elastic connecting belt is arranged on the top of the first piston plate, and one end of the elastic connecting belt away from the first piston plate is fixedly connected to the first connecting head. The telescopic cavity under the second piston plate is connected to the air intake mechanism, and the telescopic cavity under the second piston plate is connected to the negative pressure pump.

[0012] Furthermore, the number of the telescopic holes is three, and the three telescopic holes are distributed in a triangle on the top of the fixing box. Through holes are opened on the upper sides of the telescopic holes, and the through holes penetrate the fixing box. In the initial state, the first connector does not completely cover the through holes.

[0013] Furthermore, the air intake mechanism includes an air intake hole which is opened on the side wall of the fixed box and connected with the telescopic cavity, a limiting groove is opened on the side wall of the air intake hole, a plurality of air intake grooves are opened on the side wall of the limiting groove, a sealing plate is slidably connected in the limiting groove, the sealing plate is fixedly connected to a pressing handle at one end away from the telescopic cavity, a sealing ring is sleeved on the pressing handle between the sealing plate and the surface of the limiting groove at one end away from the telescopic cavity, and a return spring is arranged in the limiting groove between the sealing plate and the surface of the limiting groove at one end close to the telescopic cavity.

[0014] Furthermore, a connecting hole is provided at one end of the first connecting head close to the second connecting head, and a connecting shaft is provided at one end of the second connecting head close to the first connecting head; magnetic suction parts are provided at the bottom of the connecting hole and the top of the connecting shaft.

[0015] Furthermore, an arc-shaped fixing seat adapted to the outer surface of the vascular sheath is fixedly connected to the top of the fixing plate, and the fixing strap is a first elastic strap and a second elastic strap hinged at both ends of the arc-shaped fixing seat, and the first elastic strap and the second elastic strap are respectively provided with a second bonding portion and a second bonding surface on the surface of the side away from the arc-shaped fixing seat, and the second bonding portion and the second bonding surface are detachably connected.

[0016] Furthermore, two layers of arc-shaped electrical connection plates are arranged on the inner side wall of the telescopic hole, and the number of arc-shaped electrical connection plates on each layer is at least two. The side wall of the first connector is provided with electrical connection contacts corresponding to the number of arc-shaped electrical connection plates, and the electrical connection contacts are telescopic structures. A controller is arranged in the fixed box, and the controller is connected to the arc-shaped electrical connection plates and the negative pressure pump signal.

[0017] The controller is used to record the order in which the power contact point contacts the two layers of arc-shaped power contact pieces. When the power contact point contacts the lower arc-shaped power contact piece first and then the upper arc-shaped power contact piece, and when it is detected that the power contact point is separated from the upper arc-shaped power contact piece and then contacts the upper arc-shaped power contact piece again, the negative pressure pump is controlled to start running; when the power contact point contacts the upper arc-shaped power contact piece first and then the lower arc-shaped power contact piece, the negative pressure pump is controlled to stop running.

[0018] Furthermore, the controller is used to receive a contact time limit preset by the user. When the power contact first contacts the lower arc-shaped power contact piece and then contacts the upper arc-shaped power contact piece, the controller detects the time length for the power contact to contact with the upper arc-shaped power contact piece again after being separated from the upper arc-shaped power contact piece. When the time length for the power contact to contact with the upper arc-shaped power contact piece again meets the contact time limit, the negative pressure pump is controlled to start running.

[0019] The technical principles of the above scheme are as follows:

[0020] Basic fixing part: The fixing box can be conveniently fixed to the patient's limb through the fixing ring. For example, when performing an imaging interventional surgery based on the patient's radial artery, the puncture site is usually located at the radial artery at the patient's wrist. Therefore, the fixing box can be fixedly connected to the patient's wrist through the fixing ring. The main purpose of the fixing box is to provide a base for fixing the vascular sheath. The vascular sheath is fixed to the arc-shaped fixing seat by a fixing strap. Since the fixing seat can be separated from the arc-shaped fixing box, and the arc-shaped fixing seat is adapted to the shape of the vascular sheath, the two can be conveniently fixed and connected. The vascular sheath can be connected and fixed to the fixing box through the first connector and the second connector. Then, by starting the negative pressure pump, the first piston plate and the second piston plate in the telescopic chamber move downward, thereby pulling the first connector and the second connector and the arc-shaped fixing seat above them to move downward synchronously until the first connector is completely retracted in the telescopic hole and remains locked.

[0021] Intraoperative fixation part: When the vascular sheath needs to be held in the hand for coordinated use with the instrument, the pressing handle can be pressed to restore the telescopic chamber below the second piston plate in a negative pressure state to the same air pressure as the outside world, so that the first piston plate and the second piston plate are displaced upward and reset, and the first connecting head is restored to a released state, so that the medical staff can hold the vascular sheath and use it in coordination with the instrument; and after use, based on the contact situation of the arc-shaped power contact piece and the power contact point, the controller can automatically control the negative pressure pump to run again to completely retract the first connecting head into the telescopic hole and keep it in a locked state, thereby fixing the vascular sheath again.

[0022] The non-contact structure of the first piston plate and the second piston plate, during the downward movement of the second piston plate, the negative pressure is generated by the space retained between the two to pull the first piston plate downward. Since there are tension springs and compression springs in the initial stage of the downward movement of the first piston plate, the displacement speed of the first piston plate and the second piston plate can be limited, and as the connecting belt gradually drives the first connecting head to be telescopic into the telescopic hole, the through hole is gradually closed. Therefore, the first connecting head is subsequently carried downward gradually by the negative pressure in the space above the first piston plate, and finally locked in the telescopic hole by the negative pressure in the space above the first piston plate.

[0023] The above scheme has the following beneficial effects:

[0024] 1. The present invention can conveniently fix the vascular sheath by means of a detachable fixing box and a fixing plate, which are used to provide a fixing base and connect and fix the vascular sheath respectively; at the same time, through the structure that can conveniently separate the fixing box, it can provide stable and effective fixation for the vascular sheath during the interventional surgery, and can conveniently adjust the vascular sheath from a locked state to a released state when the operator needs to hold the vascular sheath, meeting the operator's use needs. Compared with the existing technology, it can meet both the fixation needs of the vascular sheath and the convenient holding and use needs of the vascular sheath.

[0025] 2. Compared with the fixing method using medical bandages, the present invention can be fixed and separated more conveniently, ensuring that medical staff can use it quickly during use and can quickly fix it after use; compared with the traditional detachable separation method, the connection is based on the corresponding connector and is locked and fixed by negative pressure, the fixing stability is stronger and the separation process is simpler.

[0026] 3. The present invention locks the first connecting head through the structure of the first piston plate and the second piston plate and the connecting belt and the through hole. This locking method is more stable during the process of retracting the first connecting head. When the operating power of the negative pressure pump remains unchanged, the speed of the first piston plate moving downward will gradually decrease due to the tension spring and the compression spring, and the speed of pulling the first connecting head to retract into the telescopic hole will also be slower. In the initial stage of the downward movement of the first piston plate, it is mainly driven by the connecting belt. When the first piston plate completely covers the through hole, it is driven by the connecting belt and negative pressure. At the same time, when the first connecting head is completely retracted into the telescopic hole, since it has completely covered the through hole, the negative pressure formed in the telescopic cavity can lock the first connecting head into the telescopic hole, thereby fixing the vascular sheath and reducing the impact on the contact position between the vascular sheath and the patient's wound during the contraction and locking process.

[0027] 4. The present invention, in combination with a controller, realizes automatic fixation of the vascular sheath. Based on the controller recording the displacement and separation of the first connector in the telescopic hole, it can intelligently judge the usage of the vascular sheath. After judging that the use of the vascular sheath is completed, it can actively control the operation of the negative pressure pump to realize automatic fixation of the vascular sheath.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1, as Figure 1-Figure 4 As shown: an image interventional surgery treatment auxiliary device, mainly including a fixing box 3 and a fixing ring, wherein the fixing box 3 serves to provide a fixing base, and the fixing ring serves to fix the fixing box 3; there is no restriction on the shape of the fixing box 3, but since the fixing box 3 involves contact with the patient's limbs, the end face of the fixing box 3 close to the fixing ring is preferably set to an arc structure, so that after the fixing box 3 is fixed, it can ensure that it is firmly fixed to the patient's limbs, while also avoiding fixed pressure on the surface of the patient's limbs. In addition, an anti-skid pad 14 can be bonded and fixed in the arc structure area, and the anti-skid pad 14 is preferably made of a material with good biocompatibility, such as polypropylene (PP), polyvinyl chloride (PVC), etc.

[0042] The fixing box 3 is arranged on the fixing ring, and the fixing box 3 can be fixedly connected to the patient's limbs through the fixing ring. Specifically, the fixing ring includes a first elastic fixing belt 1 and a second elastic fixing belt 2, and the first elastic fixing belt 1 and the second elastic fixing belt 2 are both made of materials with a certain elasticity, and need to have good biocompatibility to avoid excessive squeezing of the patient's limbs. One end of the first elastic fixing belt 1 and the second elastic fixing belt 2 are both hinged to the fixing box 3, and the first elastic fixing belt 1 and the second elastic fixing belt 2 are respectively provided with a first adhesive portion 16 and a first adhesive surface 17 on the surface of the side away from the fixing box 3, and the first adhesive portion 16 and the first adhesive surface 17 are detachably connected. The first adhesive portion 16 and the first adhesive surface 17 used in this embodiment are paired Velcro, so that the fixing box 3 can be conveniently fixed and can adapt to the limb conditions of different patients.

[0043] For example: when performing an imaging interventional surgery based on the patient's radial artery, the puncture site is usually located at the radial artery at the patient's wrist. Therefore, it is only necessary to wrap the first elastic fixing belt 1 and the second elastic fixing belt 2 around the patient's wrist and temporarily fix their positions through the first adhesive portion 16 and the first adhesive surface 17.

[0044] Combination Figure 5-Figure 7 As shown, a telescopic assembly is arranged inside the fixed box 3, at least one telescopic hole is opened on the top of the fixed box 3, a connecting assembly is arranged in the telescopic hole, the connecting assembly includes a first connector 4, and the telescopic assembly is used to control the displacement of the first connector 4 of the connecting assembly along the telescopic hole. Specifically, the telescopic assembly includes a telescopic cavity opened inside the fixed box 3, a first piston plate 20 and a second piston plate 21 slidably connected in the telescopic cavity, the first piston plate 20 is located between the second piston plate 21 and the top wall of the telescopic cavity, and the first piston plate 20 and the second piston plate 21 are not in contact, a tension spring 23 is arranged between the first piston plate 20 and the top wall of the telescopic cavity, and a compression spring 22 is arranged between the second piston plate 21 and the bottom of the telescopic cavity; the tension spring can gradually increase the difficulty of the first piston plate 20 moving downward along the telescopic cavity as the first piston plate 20 moves downward, and the second piston plate 21 is limited by the compression spring 22. Thus, the first piston plate 20 and the second piston plate 21 can move downward stably. The telescopic chamber below the second piston plate 21 is connected to a negative pressure pump 15, which is used to generate negative pressure below the second piston plate 21. The negative pressure pump 15 needs to be of a one-way air intake type. In the present embodiment, the air in the telescopic chamber is allowed to be discharged to the outside, and the outside air cannot enter the telescopic chamber through the negative pressure pump 15.

[0045] An elastic connecting belt 24 is hinged on the top of the first piston plate 20. The elastic connecting belt 24 is fixedly connected to the first connector 4 at one end away from the first piston plate 20. The elastic connecting belt 24 is relatively long and is not stretched in the initial state. And a through hole 11 is opened on the upper side of the telescopic hole, and the through hole 11 passes through the fixing box 3. In the initial state, the first connecting head 4 does not completely cover the through hole 11, that is, in the initial stage of the first piston plate 20 moving downward, since the through hole 11 is not completely covered, the upper space of the first piston plate 20 is in a state equal to the external pressure. As the second piston plate 21 moves downward, negative pressure is generated under the first piston plate 20, thereby promoting the first piston plate 20 to move downward more quickly, so that the elastic connecting belt 24 is quickly straightened, and then the first connecting head 4 is pulled to shrink into the telescopic hole. After covering the through hole 11, the upper space of the first plug plate is gradually in a negative pressure state, thereby increasing the difficulty of the first piston plate 20 moving downward, so that the first connecting head 4 continues to shrink into the telescopic hole at a slower speed, and finally locks it in the telescopic hole through the negative pressure formed in the upper space of the first piston plate 20.

[0046] The telescopic cavity below the second piston plate 21 is connected to an air intake mechanism, which is used to restore the pressure of the space below the second piston plate 21 to be equal to the external pressure, thereby resetting the second piston plate 21 through the elastic force of the compression spring 22. During this process, the first piston plate 20 is simultaneously reset upward, pushing the first connecting head 4 to extend out of the telescopic hole. When the first connecting head 4 is restored to not cover the through hole 11, the upper space of the first piston plate 20 is connected to the outside through the through hole 11, so that the first connecting head 4 is no longer pushed, thereby releasing the lock on the first connecting head 4.

[0047] The present embodiment provides a specific air intake mechanism structure, the air intake mechanism includes an air intake hole provided on the side wall of the fixed box 3 and connected to the telescopic cavity, a limiting groove 27 is provided on the side wall of the air intake hole, a plurality of air intake grooves 28 are provided on the side wall of the limiting groove 27, a sealing plate 30 is slidably connected in the limiting groove 27, the sealing plate 30 is fixedly connected to the pressing handle 12 at one end away from the telescopic cavity, a sealing ring 31 is sleeved on the pressing handle 12 between the sealing plate 30 and the surface of the limiting groove 27 at one end away from the telescopic cavity, and a return spring 29 is provided in the limiting groove 27 between the sealing plate 30 and the surface of the limiting groove 27 at one end close to the telescopic cavity. In order to facilitate the outside air to enter the telescopic cavity through the air intake hole, it is preferred to reserve a sufficient gap between the inner side wall of the air intake hole and the side wall of the pressing handle 12. Figure 7 As shown, in this embodiment, a circular groove is provided to limit the sliding of the pressing handle 12. In order to facilitate the outside air to enter the telescopic cavity through the air inlet hole, a corresponding through groove or through hole 11 is provided on the pressing handle 12. By pressing the pressing handle 12, the sealing plate 30 and the sealing ring 31 slide to the corresponding area of ​​the air inlet groove 28, and the outside air passes through the air inlet hole-the air inlet groove 28-the air inlet hole in sequence and finally enters the telescopic cavity.

[0048] The first connector 4 is detachably connected to the second connector 13. Specifically, a connection hole 25 is provided at one end of the first connector 4 close to the second connector 13, and a connection shaft 26 is provided at one end of the second connector 13 close to the first connector 4. Magnetic elements are provided at the bottom of the connection hole 25 and the top of the connection shaft 26. The magnetic elements used in this embodiment are ordinary permanent magnets. By bringing the second connector 13 close to the first connector 4 and inserting the connection shaft 26 into the connection hole 25, the two can be conveniently fixed by the magnetic attraction of the permanent magnet.

[0049] The second connector 13 is fixedly connected to a fixing plate 5 at one end away from the first connector 4, and an arc-shaped fixing seat 6 adapted to the outer surface of the vascular sheath is fixedly connected to the top of the fixing plate 5. A fixing band is provided on the arc-shaped fixing seat 6, and the fixing band is used to connect and fix the fixing plate 5 with the vascular sheath. The fixing band is a first elastic band 8 and a second elastic band 7 hinged at both ends of the arc-shaped fixing seat 6. The first elastic band 8 and the second elastic band 7 are respectively provided with a second adhesive portion 9 and a second adhesive surface 10 on the surface of the side away from the arc-shaped fixing seat 6, and the second adhesive portion 9 and the second adhesive surface 10 are detachably connected. The second adhesive portion 9 and the second adhesive surface 10 of this embodiment also use paired Velcro, so that the vascular sheath can be conveniently connected and fixed to the arc-shaped fixing seat 6. Since the vascular sheath is connected and fixed to the arc-shaped fixing seat 6 mainly based on the first connector 4 and the second connector 13 in the telescopic hole to realize its connection and fixation with the fixing box 3 as the base, the key to its stability also lies in the number of telescopic holes. This embodiment uses three telescopic holes, and adopts a triangular distribution method to ensure stability after fixation.

[0050] The specific implementation process is as follows: separate the first connector 4 and the second connector 13, and fix the fixing box 3 as the base on the patient's limb through the first elastic fixing belt 1 and the second elastic fixing belt 2, depending on the actual situation of the interventional surgery; fix the vascular sheath to the arc-shaped fixing seat 6 through the first elastic band 8 and the second elastic band 7, and then fix the first connector 4 and the second connector 13, start the negative pressure pump 15 to run until the first connector 4 is completely locked in the telescopic hole, thereby completing the fixation of the vascular sheath. When it is necessary to hold the vascular sheath for use, the first connector 4 is released by pressing the pressing handle 12, so that the vascular sheath can be held normally for use. After use, it needs to be fixed again, and it only needs to start the negative pressure pump 15 again until the first connector 4 is completely locked in the telescopic hole.

[0051] Embodiment 2, in order to further improve the convenience of the device during use, is different from Embodiment 1 in that: two layers (respectively located on the upper and lower sides of the telescopic hole, corresponding to the locking release position and the locking position of the first connector 4) of arc-shaped electrical contact plates 19 are fixedly connected to the inner wall of the telescopic hole, and the number of arc-shaped electrical contact plates 19 in each layer is at least two, and it is necessary to ensure that the surface of the arc-shaped electrical contact plate 19 is flush with the inner wall of the telescopic hole to avoid interference with the telescopic movement of the first connector 4.

[0052] The side wall of the first connector 4 is provided with power contact points 18 corresponding to the number of arc-shaped power contact pieces 19. The power contact points 18 are retractable structures. The specific structure can refer to the charging contact structure at hand, and will not be repeated in this embodiment. A controller is provided in the fixing box 3, and the controller is connected to the arc-shaped power contact piece 19 and the negative pressure pump 15 by signal.

[0053] The controller is used to record the order in which the power contact 18 contacts the two layers of arc-shaped power contact pieces 19. When the power contact 18 contacts the lower arc-shaped power contact piece 19 first and then the upper arc-shaped power contact piece 19, and when it is detected that the power contact 18 separates from the upper arc-shaped power contact piece 19 and then contacts the upper arc-shaped power contact piece 19 again (indicating that the operator releases the lock on the vascular sheath and puts the vascular sheath back after using it), the negative pressure pump 15 is controlled to start running to achieve the locking of the vascular sheath.

[0054] When the power contact 18 first contacts the upper arc-shaped power contact piece 19 and then contacts the lower arc-shaped power contact piece 19 (indicating that the first connector 4 is effectively locked), the negative pressure pump 15 is controlled to stop running.

[0055] In order to reduce the possibility of the controller misjudging and locking the vascular sheath in advance, the controller is also used to receive a contact time limit preset by the user. When the power contact 18 first contacts the lower arc-shaped power contact piece 19 and then contacts the upper arc-shaped power contact piece 19, the controller detects the time length for the power contact 18 to contact the upper arc-shaped power contact piece 19 again after separating from the upper arc-shaped power contact piece 19. When the time length for the power contact 18 to contact the upper arc-shaped power contact piece 19 again meets the contact time limit, the negative pressure pump 15 is controlled to start running.

[0056] In addition, the pressing control of the pressing handle 12 can also be achieved by setting an electromagnet in the limit groove 27 to prompt the pressing handle 12 to slide. After the electromagnet is connected to the controller signal, the air entering under the second piston plate 21 can be controlled based on the controller, further improving the operator's convenience during operation.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
