Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to an intraoperative real-time ABI measurement and foot and ankle fixation device. Background Technology

[0002] Patients with lower extremity arterial diseases often experience involuntary lower limb movements during surgery due to pain and inability to cooperate with the procedure. This can severely affect the surgical outcome and progress. In particular, during endovascular treatment of lower extremity arteries, involuntary limb movements can increase X-ray exposure time, contrast agent dosage, and may even lead to the need for general anesthesia or termination of the surgery due to the patient's inability to cooperate. Therefore, a device that can fix the patient's affected limb during surgery is needed.

[0003] However, existing devices for immobilizing a patient's affected limb often have the following problems:

[0004] (1) The material of the device used to fix the patient’s limb often affects the penetration of X-rays and lacks specificity for different ulcer surfaces on the affected foot.

[0005] (2) The existing devices for fixing the patient’s affected limb cannot obtain the patient’s ankle-brachial index (i.e., the ratio between ankle artery pressure and brachial artery pressure by measuring the systolic pressure of the posterior or anterior tibial artery and the brachial artery at the ankle, which is the most commonly used and simplest indicator for the effect of lower limb arterial surgery).

[0006] (3) The existing Chinese utility model patent CN217014581U provides an operating table with an adjustable hand and foot fixation device, which is not suitable for patients undergoing lower limb vascular surgery. During the operation, it is impossible to further clarify the surgical effect through specific data (ankle-brachial index). Moreover, the Chinese utility model patent CN217014581U is large in size and lacks flexibility, which affects the doctor's operation on the lower leg. Utility Model Content

The position in which the second fixing part 32 snaps into the first mating part 10a is such that the ankle pad unit 30 is located between the ankle pressure measuring unit 20 and the embedding groove 10b.

[0052] Figure 5 This is a cross-sectional schematic diagram of an ankle support pad according to an embodiment of the present invention.

[0053] like Figure 5 As shown, the ankle support pad 33 is used for placing the patient's ankle on it. The bottom of the ankle support pad 33 is recessed with a downward-facing matching groove 33a. The matching groove 33a has a lateral recess around its interior, referred to as the snap-fit ​​groove 33b.

[0054] like Figure 1 , Figure 2 as well as Figure 5 As shown, the matching groove 33a is sized to fit and is embedded in the second main body 31; the snap-fit ​​groove 33b and the side protrusion 31a are matched and snap-fitted together (snap-fit ​​connection), so that the ankle pad 33 is placed on the second main body 31 and completely covers the upper surface and periphery of the second main body 31.

[0055] Specifically, in this embodiment, the ankle support pad 33 is made of soft material, and the side of the ankle support pad 33 used to place the patient's ankle is curved.

[0056] In a variation of this embodiment, the second main body 31 does not have a lateral protrusion 31a, and the ankle pad 33 does not have a matching groove 33a and a snap-fit ​​groove 33b; the second main body 31 and the ankle pad 33 are detachably connected by their respective built-in magnets.

[0057] Figure 6 This is a cross-sectional schematic diagram of the intraoperative real-time ABI measurement and foot and ankle fixation device of an embodiment of this utility model at the connection between the first base plate and the second base plate.

[0058] like Figure 1 , Figure 2 as well as Figure 6As shown, the second base plate 40 has an internal threaded hole 40a. The second base plate 40 is sized to match the embedding groove 10b of the first base plate 10 and is embedded and fixed therein, so that the planes of the second base plate 40 and the first base plate 10 are at 120° or 145° to each other.

[0059] In a variation of this embodiment, the first base plate 10 does not have an embedded groove 10b, the second base plate 40 is not connected to the first base plate 10 by a slot, but is directly connected by a hinge, and the adjustable angle between the second base plate 40 and the first base plate 10 is 120° to 145°.

[0060] like Figure 1 and Figure 2 As shown, the foot fixing unit 50 includes a fixing base plate 51 and a fixing strap 52.

[0061] The fixation base plate 51 is used to place the patient's foot and has a countersunk hole 51a without internal threads. The countersunk hole 51a and the internally threaded hole 40a are sized to match each other. The fixation base plate 51 is rotatably mounted on the second base plate 40 by bolts 1 passing through the countersunk hole 51a and the internally threaded hole 40a. The top of the fixation base plate 51 is at least 4 cm lower than the second base plate 40, thereby preventing the sterile sheet from pressing on the patient's foot and causing pressure when using the intraoperative real-time ABI measurement and foot and ankle fixation device 100.

[0062] Figure 7 This is a cross-sectional schematic diagram of the fixed substrate according to an embodiment of the present invention.

[0063] like Figure 7 As shown, at least one second mating portion 51b is provided on the fixed substrate 51. Specifically, in this embodiment, the second mating portion 51b is a channel structure that is narrow at both ends and wide in the middle.

[0064] The fixation strap 52 is disposed on the fixation base plate 51 and is used to bind the patient's foot to the fixation base plate 51.

[0065] Figure 8 This is an exploded view of the heel pad unit according to an embodiment of the present invention; Figure 9 This is a cross-sectional schematic diagram of the heel pad according to an embodiment of the present invention.

[0066] like Figure 1 , Figure 2 , Figure 8 as well as Figure 9 As shown, the heel pad unit 60 includes a third main body 61, a third fixing part 62, and a heel pad 63.

[0067] The third main body 61 serves as the main body of the heel pad unit 60.

Specifically, in this embodiment, the third fixing part 62 is two hollow strip-shaped structures that are narrow at both ends and wide in the middle. The third fixing part 62 and the second mating part 51b are matched and snapped into place, so that the entire heel pad unit 60 is detachably mounted on the fixing base plate 51.

[0069] The heel pad 63 is used for placing the patient's heel on it. The bottom of the heel pad 63 is recessed with a fitting groove 63a that matches the size of the third main body 61, so that the heel pad 63 is slotted into the third main body 61 and completely covers the upper surface and periphery of the third main body 61.

[0070] Specifically, in this embodiment, the heel pad 63 is made of soft material, and the side of the heel pad 63 used to place the patient's heel is curved.

[0071] like Figure 1 and Figure 2 As shown, the toe pressure measuring unit 70 is a pressure measuring cuff disposed on the fixed base plate 51, used to measure the pressure of the distal arterioles of the toes of the patient's foot, which is fixed to the fixed base plate 51.

[0073] In this embodiment, the various power-consuming components of the intraoperative real-time ABI measurement and foot and ankle fixation device 100 are powered by a storage battery. The intraoperative real-time ABI measurement and foot and ankle fixation device 100 in this embodiment is made of X-ray-transparent materials such as plastic and sponge.

[0074] The use and operation process of an intraoperative real-time ABI measurement and foot and ankle fixation device 100 in this embodiment includes the following steps S10 to S60:

[0075] S10, medical staff secure the patient's ankle to be operated on using the pressure-measuring cuff of the ankle pressure measuring unit 23, and place the patient's ankle on the ankle pad 33. During this process, by adjusting the engagement of the first fixing part 22 and the second fixing part 32 with different first mating parts 10a, the positions of the ankle pressure measuring unit 20 and the ankle pad unit 30 on the first base plate 10 are adjusted to suit the ankle lengths of different patients.

[0076] S20, the second base plate 40 is inserted into the corresponding 120° or 145° insertion groove 10b, and then the patient's foot is placed on the fixing base plate 51 and secured by the fixing strap 52. During this process, the angle between the fixing base plate 51 and the second base plate 40 is rotated to adapt to the angle of lateral inclination of the foot of different patients.

[0077] S30, place the patient's heel on the heel pad 63, and fix the toes with the pressure measuring cuff of the toe pressure measuring unit 70 to measure the pressure of the peripheral arterioles.

[0078] S40, by switching on the ankle pressure measuring unit 23 and the toe pressure measuring unit 70, the patient's ankle arterial pressure and peripheral arteriolar pressure are measured respectively.

[0079] S50, medical staff then measure the patient's brachial artery pressure separately, and combine the ankle artery pressure and brachial artery pressure to obtain the patient's ankle-brachial index.

[0080] The role and effect of the embodiments

[0081] According to this embodiment, an intraoperative real-time ABI measurement and ankle fixation device includes: a first base plate; an ankle pressure measuring unit, which is adjustablely positioned on the first base plate along its length direction for fixing the patient's ankle and measuring ankle arterial pressure; an ankle pad unit, which is adjustablely positioned on the first base plate along its length direction for placing the patient's ankle on it; a second base plate, which is adjustablely positioned at one end of the first base plate near the ankle pad unit along its length direction; and a foot fixation unit, which is disposed on the side of the second base plate near the ankle pad unit for fixing the patient's foot on it. The intraoperative real-time ABI measurement and ankle fixation device is made of X-ray transparent material.

[0082] Therefore, the intraoperative real-time ABI measurement and foot and ankle fixation device of this embodiment has the following beneficial effects:

[0083] (1) It is suitable for patients with lower extremity arterial diseases such as arteriosclerosis obliterans. When performing endovascular or open surgery, the foot and ankle are fixed, lower extremity blood pressure is measured and the ankle-brachial index is calculated, so as to compare the effects before and after surgery.

[0084] (2) The material is lightweight and X-rays can pass through it, so it can be used under DSA.

[0085] (3) All are modular units that can be disassembled and moved to accommodate patients with different sizes and conditions of foot.

[0086] (3) It is small in size, easy to place, and does not affect the operation of medical staff.

[0087] (4) It can safely, comfortably and efficiently immobilize the patient's affected limb. In addition, by combining the patient's brachial artery pressure measured in real time by medical staff, the patient's ankle-brachial index can be obtained, thus enabling a comparison of the effects before and after surgery.

[0088] (5) Applicable to fixation of the foot with ulcers in various locations.

[0089] Furthermore, the first base plate is recessed or has several arrayed first mating parts along its length. The foot and ankle pressure measurement unit includes: a first main body; a first fixing part, protruding below the first main body, the first fixing part and the first mating part being connected by a snap-fit ​​embedded fixing connection; and a foot and ankle pressure measurement part, which is a pressure measurement cuff, set above the first main body, for fixing the patient's foot and ankle and measuring ankle arterial pressure. This setting has the following beneficial effects: (1) The first mating part is inserted through the first base plate, rather than being recessed into an embedded groove, making it less likely to accumulate dirt and easier to clean; (2) The foot and ankle pressure measurement unit can measure the ankle pressure of the patient's foot and ankle while fixing the foot and ankle; (3) The foot and ankle pressure measurement unit is detachably connected to the first base plate, making the modular units of the entire intraoperative real-time ABI measurement and foot and ankle fixation device detachable and movable; (4) The foot and ankle pressure measurement unit can be detachably fixed in different first mating parts, thereby adapting to different patients' limb sizes and actual needs during surgery.

[0090] Furthermore, the first base plate is recessed or perforated along its length by a plurality of arrayed first mating parts. The foot and ankle pad unit includes: a second main body; a second fixing part, protruding below the second main body, wherein the connection between the second fixing part and the first mating part is a snap-fit ​​embedded fixing connection; and a foot and ankle pad, disposed on the second main body and at least covering the upper surface of the second main body, wherein the foot and ankle pad is used for the patient's foot and ankle to be placed on it. This configuration has the following beneficial effects: (1) The first mating parts are perforated on the first base plate, rather than recessed into an embedded groove design, which makes it difficult for dirt to accumulate and easy to clean; (2) The second fixing part is detachably connected to the first base plate, which makes the modular units of the entire intraoperative real-time ABI measurement and foot and ankle fixation device detachable and movable; (3) The second fixing part is detachably fixed in different first mating parts, thereby adapting to different patients' limb sizes and actual needs during surgery.

[0091] Furthermore, the ankle pad is made of soft material, and the side of the ankle pad used to place the patient's ankle is curved. The ankle pad completely covers the peripheral and upper surfaces of the second main body. The connection between the ankle pad and the second main body is a snap-fit ​​embedded connection. This design has the following advantages: (1) The snap-fit ​​embedded fixation between the second fixing part and the ankle pad is more reliable, and the ankle pad unit has a high degree of modularity, making it easy to disassemble, move, and clean; (2) The ankle pad is made of soft material and its curved design on the side used to place the patient's ankle makes it more suitable for the patient's ankle, improving the patient's comfort when the ankle is placed on it.

[0092] Furthermore, the first and second base plates are connected by a slot. The first base plate has at least one recessed groove along its length, near the end closest to the ankle pad unit. Along the length of the first base plate, the recessed groove forms an angle of 120° to 145° with the main plane of the first base plate. One end of the second base plate is fitted into the recessed groove. There are two recessed grooves, and along the length of the first base plate, the two recessed grooves form angles of 120° and 145° with the main plane of the first base plate, respectively. This arrangement allows for a modular and detachable connection between the first and second base plates, while also allowing for adjustment of the angle between them to accommodate different patients' normal resting foot positions.

[0093] Furthermore, the foot fixation unit includes: a fixation base plate, disposed on the second base plate, with the top of the fixation base plate being at least 4 cm lower than the second base plate; and a fixation strap, disposed on the fixation base plate, for binding the patient's foot to the fixation base plate. The intraoperative real-time ABI measurement and foot and ankle fixation device also includes a toe pressure measuring unit, which is a pressure measuring cuff disposed on the fixation base plate, for measuring the pressure of the distal arterioles of the toes of the patient's foot fixed on the fixation base plate. This configuration has the following beneficial effects: (1) The setting of the top of the fixation base plate being at least 4 cm lower than the second base plate can effectively protect the patient's foot and avoid pain caused by pressure from the sterile drape during surgery; (2) The setting of the fixation strap can better fix the patient's foot; (3) The setting of the toe pressure measuring unit can detect the pressure of the distal arterioles of the patient's toes in real time, thereby allowing medical staff to better compare the effects before and after surgery.

[0094] Furthermore, the fixing base plate has a countersunk hole without internal threads, and the second base plate has an internally threaded hole of the same size as the countersunk hole. The fixing base plate and the second base plate are rotatably connected by bolts passing through the countersunk hole and the internally threaded hole. This configuration allows the fixing base plate and the second base plate to be rotatably fixed, and the angle of the fixing base plate relative to the second base plate is adjustable to accommodate different patients' foot internal and external rotation scenarios.

[0095] Furthermore, the fixing base plate has a recessed or perforated second mating part. The intraoperative real-time ABI measurement and ankle fixation device also includes a heel pad unit, which includes: a third main body; a third fixing part protruding below the third main body, the third fixing part being connected to the second mating part in a snap-fit ​​embedded fixing relationship; and a heel pad covering the peripheral and upper surfaces of the third main body for the patient's heel to rest on. With this design, when the patient's heel skin is ulcerated, the heel pad unit can be removed to avoid pressure on the heel.

[0096] Furthermore, the heel pad is made of soft material, and the side of the heel pad used to support the patient's heel is curved. The connection between the heel pad and the third main body is a slot-type embedded fixed connection.
