Description

Technical Field

[0001] This utility model relates to an auxiliary device for interventional cardiovascular and cerebrovascular procedures. More specifically, this utility model relates to an adjustable stent for interventional surgery. Background Technology

[0002] Interventional surgery is a minimally invasive treatment guided by imaging in clinical practice. Before the procedure, surgical drapes are used to isolate the patient from the external space, and then the surgery is performed using instruments such as catheters and guidewires. During the procedure, sterile drapes are directly laid on the patient, and an incision is made according to the patient's wound location. Especially during pacemaker implantation surgery, surgical drapes are usually used to directly cover the patient's entire face. Throughout the procedure, the patient's mouth and nose are constantly covered by sterile drapes, which can lead to feelings of pressure, difficulty breathing, anxiety, and even inability to cooperate with the surgery. To address this issue, the inventors developed an existing patent (CN211723842U) that provides an adjustable headrest for angiography machines. The adjustable headrest is installed on the treatment bed during use and needs to be removed when not in use. However, during use, it was found to have drawbacks such as a small adjustment range, inconvenient storage, and a large footprint. Existing patent (CN115813421A) also discloses an adjustable head support for CT interventional surgery, but it needs to be placed on the examination bed and cannot be stably placed during the operation, affecting the operator's operation; at the same time, its adjustment range is also limited by the width of the angiography machine. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide an intraoperative adjustable stent for interventional surgery, which can be installed on the operating table before surgery; its height and opening angle can be adjusted at will according to the needs of the surgery; it is convenient and quick to store and fold, occupies little space, and saves time and effort.

[0005] To achieve these objectives and other advantages according to the present invention, an intraoperative adjustable stent for interventional surgery is provided, comprising:

[0006] A support frame comprising at least two horizontal support rods arranged in an umbrella shape; the support frame, when opened, is umbrella-shaped and can provide maximum support for the surgical drape.

[0007] A connecting rod, comprising a telescopically connected head rod and tail rod; a support frame connected to the top of the head rod, the support frame rotating about the connecting rod as an axis; the connecting rod is a telescopic rod, which can be a circular tube, a square tube, or a telescopic track structure. The connecting rod is preferably made of stainless steel with a certain supporting strength.

[0008] The base is disposed at the bottom end of the tail rod; the base is detachably fixed to the treatment bed board. The base is used to fix the support frame at the head of the treatment bed before surgery; therefore, the base can be any mechanical component with a connecting function.

[0009] Preferably, the support frame further includes a connecting shaft, which is rotatably connected to the top of the first rod;

[0010] The connecting shaft includes: a shaft portion coaxially arranged with the connecting rod, the shaft portion being rotatably connected to the first rod; and a support rod connector extending upward from the top of the shaft portion, the horizontal support rod being rotatably arranged on the support rod connector to realize the switching of the support frame between the unfolded state and the closed state.

[0011] Preferably, the support rod connector has a receiving groove on its periphery for accommodating the horizontal support rod, and a limiting rod perpendicular to the axial direction of the horizontal support rod is provided in the receiving groove. The limiting rod has a square cross-section.

[0012] A limiting groove is provided at the connecting end of the horizontal support rod; an enlarged first adjusting ring extends from the limiting groove of the horizontal support rod; when the limiting rod passes through the limiting groove, the horizontal support rod remains open; when the horizontal support rod is pulled so that the limiting rod is placed within the first adjusting ring, the horizontal support rod can be rotated to fold downwards into a closed state. The support frame can also use gears, buckles, or other structures to achieve the switching between its open and closed states.

[0013] Preferably, the base includes: a fixing member comprising two clamping arms that are detachably clamped to the treatment bed board;

[0014] A square pin passes through the bottom end of the tail rod; the two clamping arms are respectively fixed to the two ends of the square pin. Thus, the connecting rod can be rotated away from the treatment bed, thereby allowing the support to be stored under the treatment bed's bed board.

[0015] Preferably, the bottom end of the tail rod is provided with a positioning groove for the square pin to pass through; a second adjusting ring for the square pin to rotate extends from the edge of the positioning groove.

[0016] Preferably, the horizontal support rods are three telescopic rods. However, there may also be multiple horizontal support rods.

[0017] Preferably, the horizontal support rod comprises: interlocking, extendable tubular bodies, each with a semi-circular cross-section. The horizontal support rod, for example, has a certain width for stable support of the surgical drape.

[0018] Preferably, the connecting rod includes a telescopic head rod, a middle rod, and a tail rod that are nested together. The connecting rod employs a sleeve design to increase its stability. The middle rod and the tail rod are, for example, hollow tubes, with the bottom end of the tail rod open to the air. A one-way exhalation valve can be installed on the tube wall of the middle rod and the tail rod, and a humidity sensor is connected to the one-way exhalation valve. When the humidity in the space around the patient's head and face reaches a predetermined threshold, the one-way exhalation valve opens, promptly expelling hot and humid air with the patient's breathing, thus resolving the patient's strong "suffocating feeling" and reducing the probability of claustrophobia triggering.

[0019] Preferably, the connecting shaft is a universal joint; the shaft portion is spherical; and the top end of the first rod has a circular groove for accommodating the shaft portion.

[0020] Preferably, the two clamping arms are sheet-like pieces with a length of not less than 50 cm.

[0021] In use, insert the two clamping arms of the base onto the bed board of the treatment bed, keep the connecting rod vertical and press it down so that the square pin of the base is engaged and fixed in the positioning groove of the tail rod, thus completing the installation. Subsequently, medical staff can adjust the height of the connecting rod according to the patient's body shape and surgical requirements. Finally, open the support frame and adjust its angle and opening width as needed. After use, the horizontal support rod can be folded downwards and fitted onto the connecting rod, then the connecting rod can be retracted and folded downwards under the treatment bed board. Alternatively, the two clamping arms of the base can be directly pulled out and folded for storage.

[0022] This utility model offers at least the following advantages: The intraoperative adjustable support for interventional surgery described in this utility model has a simple and reasonable structure, is quick to install and disassemble, folds up to occupy little space, and is easy to store. When the support frame is open, it supports the surgical drape, creating a larger space around the patient's head and face, preventing symptoms such as tension or claustrophobia. The support frame can be opened or closed at any time, and the connecting rod can also be extended or retracted as needed to adjust the height of the surgical drape, thereby adjusting the size of the space around the patient's head and face. This provides sufficient operating space for the surgeon while avoiding the direct covering of the patient's mouth and nose with heavy sterile drapes, reducing the feeling of suffocation and shortness of breath during breathing, thus ensuring the patient's emotional stability during surgery. It also facilitates observation of the patient's intraoperative changes by the surgeon and circulating nurse, greatly improving surgical efficiency and safety. The support frame can rotate omnidirectionally with the connecting rod as an axis, expanding the range of angle and width adjustment. The fixing component uses a two-clamping arm design, allowing for quick installation and removal by the operator. When not in use, the support frame, the connecting rod, and the base can be quickly folded into three sections, taking up little space when stored, which greatly improves the operational efficiency of medical staff.

[0023] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figure 1 and Figure 2 As shown, an intraoperative adjustable stent for interventional surgery includes:

[0030] A support frame 100 includes at least two horizontal support rods 101 arranged in an umbrella shape; the support frame 100 is connected to the top of the connecting rod 200 via, for example, a universal joint. The support frame 100 can switch between an open and closed state. When the horizontal support rods 101 are in the horizontally open state, they can provide maximum support for the surgical drape. There are three horizontal support rods 101, evenly spaced on one side of the top of the connecting rod 200.

[0031] A connecting rod 200 is provided, which telescopically connects a first rod 201 and a last rod 202. A support frame 100 is connected to the top of the first rod 201 and can rotate around the connecting rod 200 as an axis. The connecting rod 200 is a telescopic rod, for example, a square tube, and the first rod 201 and the last rod 202 are interlocked and telescopic. The connecting rod 200 is preferably made of stainless steel with a certain supporting strength.

[0032] The system includes a base 300, which is mounted on the bottom end of the tail rod 202; the base 300 is detachably fixed to the treatment bed board. The base 300 is used to fix the support frame 100 to the head of the treatment bed before surgery. When the support frame 100 is opened, it supports the surgical drape, creating a larger space around the patient's head and face, preventing tension or claustrophobia. The support frame 100 can be opened or closed at any time, and the connecting rod 200 can also be extended or retracted as needed to adjust the height of the surgical drape, thereby adjusting the size of the space around the patient's head and face. This provides sufficient operating space for the surgeon while ensuring the patient's emotional stability during surgery, greatly improving surgical efficiency and safety.

[0033] like Figure 2 As shown, in one embodiment, the support frame 100 further includes a connecting shaft 102, which is rotatably connected to the top end of the first rod 201;

[0034] The connecting shaft 102 includes: a shaft portion 1021, coaxially arranged with the connecting rod 200, the shaft portion 1021 being rotatably connected to the first rod 201; and a support rod connector 1022, extending upward from the top of the shaft portion 1021, the horizontal support rod 101 being rotatably mounted on the support rod connector 1022, enabling the support frame 100 to switch between an unfolded state and a closed state. The support frame 100 can rotate about the connecting rod 200 as an axis, thereby allowing for real-time adjustment of the position of the surgical drape and ensuring spatial stability of the patient's head and face.

[0035] like Figure 2As shown, in one embodiment, the periphery of the support rod connector 1022 is provided with a receiving groove 1023 for accommodating the horizontal support rod. A limiting rod 1024 perpendicular to the axial direction of the horizontal support rod 101 is provided in the receiving groove 1023. The limiting rod 1024 has a square cross section. The limiting rod 1024 is used to keep the horizontal support rod 101 in a horizontal state when it is opened.

[0036] A limiting groove 103 is provided at the connecting end of the horizontal support rod 101. The limiting groove 103 is, for example, square, and is used to fix the horizontal support rod 101 in a horizontal state after being tightly fitted with the limiting rod 1024. An enlarged first adjusting ring 104 extends from the end of the horizontal support rod 101 through the limiting groove 103. When the limiting rod 1024 passes through the limiting groove 103, the horizontal support rod 101 remains open. When the horizontal support rod 101 is pulled so that the limiting rod 1024 is placed in the first adjusting ring 104, the horizontal support rod 101 can rotate, and the operator can fold it downwards to close it. The connecting end of the horizontal support rod 101 can also use a rotatable and adjustable mechanical structure such as an adjusting gear to switch between its open and closed states. Thus, the operator can quickly open and close the support frame 100, improving the efficiency of preoperative preparation and postoperative cleaning. At the same time, when not in use, the support frame 100 can be folded and stored under the treatment bed board, without occupying the surgeon's operating space, and without the need for repeated installation and disassembly in different operating rooms, further improving the efficiency of preoperative preparation.

[0037] like Figure 2 As shown, in one embodiment, the base 300 includes a fixing member 301, which includes two clamping arms that are detachably clamped to the treatment bed board; in use, the two clamping arms are simply inserted into the treatment bed board.

[0038] A square pin 302 passes through the bottom end of the tail rod 202; the two clamping arms are respectively fixed to both ends of the square pin 302. The fixing member 301 is integrally formed with the square pin 302, for example. The fixing member 301 can be directly inserted into the treatment table, allowing for quick and convenient installation and removal, without occupying the surgeon's operating space.

[0039] like Figure 2As shown, in one embodiment, the bottom end of the tail rod 202 has a positioning groove 2021 for the square pin 302 to pass through; a second adjusting ring 2022 extends from the edge of the positioning groove 2021 for the square pin 302 to rotate. Therefore, during installation, the fixing member 301 is first inserted into the treatment bed board, and the connecting rod 200 is kept vertical and pressed downwards; the directional pin 302 is then engaged in the positioning groove 2021. When not in use, the operator lifts the connecting rod 200 upwards, moving the square pin 302 into the second adjusting ring 2022. The connecting rod 200 can then be folded in the opposite direction and rotated away from the treatment bed, thereby allowing the bracket to be stored under the treatment bed board.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the horizontal support rod 101 consists of three telescopic rods, evenly spaced on the support rod connector 1022. This increases the support area and stability of the surgical drape. Rotating the connecting shaft 102 also adjusts the support position, allowing for real-time adjustment of the position and size of the space formed in the patient's head and face according to the surgeon's operating habits and the patient's body shape, providing a comfortable space for both the patient and the surgeon.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the horizontal support rod 101 includes: interlocking telescopic tubular bodies, each with a semi-circular cross-section. Therefore, when stored, the horizontal support rod 101 can be folded into a circular shape and tightly fitted against the connecting rod 200, further reducing the space occupied.

[0042] like Figure 2 As shown, in one embodiment, the connecting rod 200 includes a telescopic head rod 201, a middle rod, and a tail rod 202 that are nested together. This increases the support height and strength of the invention. The connecting rod 200 employs a sleeve design, which enhances its stability.

[0043] like Figure 3 As shown, in one embodiment, the tail rod 202 has a hollow structure, and its bottom end has an opening 203 that communicates with the air. A one-way exhalation valve 204 is provided on the side wall of the tail rod 202. When opened, the one-way exhalation valve 204 discharges hot and humid gas through the opening 203. The one-way exhalation valve 204 is connected to a humidity sensor, for example. When the humidity of the gas in the space around the patient's head and face reaches a preset threshold, the one-way exhalation valve 204 is opened to facilitate the discharge of hot and humid gas from the space, thus solving the problem of the patient's strong "suffocating feeling" and reducing the probability of claustrophobia triggering.

[0044] like Figure 2 As shown, in one embodiment, the connecting shaft 102 is a universal joint; the shaft portion 1021 is spherical; and the top end of the first rod 201 has a circular groove (not shown in the figure) for accommodating the shaft portion. Of course, the connecting shaft 102 can also be other universal joint structures to allow the support frame 100 to be adjusted in angle and direction at will.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the two clamping arms are sheet-like pieces with a length of not less than 50 cm. The fixing member 301 adopts a relatively long sheet-like structure, which can be directly inserted into the bed board to increase its stability without affecting the patient's comfort.

[0046] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
